Description

ϊ 528876 V. Description of the invention (1) [Application field of the invention] The present invention relates to a judgment logic, and more particularly to a method and a device for judging a strong earthquake that can judge the occurrence of a strong earthquake. [Background of the Invention] The occurrence of an earthquake is not only unpredictable, but also causes heavy casualties and property losses in the area where the earthquake occurred. For example, the 1992 earthquake in Taiwan in 1988 was an obvious example. Among them, there are many causes of casualties and property damage, such as fires caused by building collapse, gas explosion or fire escape, or property damage caused by failure of precision equipment. Among these casualties and losses, some of the buildings depend on the increase in the strength of the building, while others, such as gas equipment and electrical equipment, can in fact still be used for earthquake warning and cutting by appropriate methods. Therefore, how to establish a reliable method for judging strong earthquakes, which is applied to equipment such as microcomputer gas meters, mass transit vehicles, precision instruments and equipment. When a strong earthquake occurs, a strong earthquake alarm can be accurately issued and the equipment power can be turned off to prevent larger disasters. In order to reduce the loss of personnel and property, it has become an important subject of research. At present, the technology for judging earthquakes and warning power outages has been considerably developed, which will be introduced one by one below. U.S. Patent No. 5,408,45 7 (Osaka Gas Co., Ltd; Kansai Gas Meter Co., Ltd) proposes to apply seismic sensors in gas meters. The method is to use a steel ball to place a In a suspended space, when the vibration occurs, the displacement of the steel ball will cause a 0 η-0 ff signal above the circuit. This signal gp can be used to represent the occurrence of vibration. The best advantage of this method

Page 4 k 528876 V. Description of the invention ⑵ The point is that its structure is simple and its power consumption is low (almost no power consumption), but the biggest disadvantage is that it cannot accurately measure the intensity of the earthquake. Therefore, a specific judgment logic must be combined to correctly determine the occurrence of an earthquake. In addition, it is prone to misjudgment due to external shock (shock), long pipelines or high-rise buildings. The Republic of China Patent No. 3 4 5, 6 1 1 (Japan Omron Co., Ltd.) proposed earthquake judgment logic for steel ball seismic sensors. The basis for judging earthquakes is the total time length of the vibration signal, The number of vibration cycles and the length of each cycle are summarized as a characteristic value of the earthquake determination and a judgment logic table is summarized. The biggest advantage of this method is that after the rule table of decision logic is established, the microcomputer control circuit will save a lot of work; and it has the disadvantages of the ball switch, which is the same as the previous patent. In addition, since the earthquake patterns in different locations are often different, this determination logic may not be applicable to the whole world.

Douglas P. Ardu ini, " Smart sensor requirements for second generation seismic gas shut — off valves " s-wave) will have a faster propagation speed. At the same time, the intensity and destructiveness of the vertical shock wave are much smaller than the horizontal shock wave. Therefore, John Andrew Michel in US Patent No. 5, 7 4 2, 2, 35 proposed a micro-vibration switch designed by a semiconductor process to detect vertical seismic waves as a precaution against earthquake disasters. The advantage of this patent is that the structure is very simple and the component cost is low; but in fact, according to the induction of seismic intensity data, it can be known that, in general,

528876 V. Description of the invention (3) The intensity of the vertical seismic wave (P-wave) is very small (about 0.01 g). Therefore, if a single vertical direction seismic sensing is used as the basis for seismic determination, it is easy to cause misjudgment. Therefore, it should be more suitable with other seismic determination methods. U.S. Patent No. 4,165,503 is a fluid-type seismic sensor that can be used to measure vibration and linear acceleration. It utilizes the joint effect of the sensing block and the sensing fluid on the pressure converter to produce a telecommunication output equivalent to a G value. The design of this sensor can be applied to a wide range of G values, which is limited only by the maximum value of the reading on the meter. The biggest difference between this design and the traditional design lies in the method of converting action into pressure output. The net pressure generated by the liquid when the vibrating block feels the pressure will be read out by the pressure converter, which is proportional to the acceleration load. U.S. Patent No. 4, 2 5 3, 1 64 is a multifunctional seismic converter. The reflection characteristics or conversion function of the output signal is a conversion function that can be arbitrarily changed to copy other seismic sensors. In particular, this change can be implemented at the measurement site. In this invention, a transfer function shaping filter (Transfer Function Shaping Filter) is provided, the center frequency of which can be adjusted to the natural frequency of the seismic sensor. The filter parameters are also designed to be tunable to match the damping effect and phase response of the seismic sensor. The transfer function of this invention includes a first transfer function of a first sensor (accelerometer or hydrophone Hydr 〇ph ο ne) to cooperate with a second sensor (ground sound sensor G e 〇ph ο ne ) Of the second conversion function. U.S. Patent No. 4,3 3 3,0 2 9 is a seismic sensor for plug-in detection, including a base, a cantilever member of piezoelectric material extending from the base, and a load cantilever member end Department of mass blocks. Base

I. V. Description of the invention (4) Forming receiving cantilever beams Accepting metal wires. The line forms a 45-degree angle, and the jacket covers the whole. This helps to mention that the U.S. patent contains a central ring circumference. , You can transport the shaft for the length. When tilting can be sensed. This ring structure has four teeth or is installed upright. When the steel ball of the national patent is placed, the small steel blockage can be required. The national patent can be used mainly for automobiles. It can increase the chute at one end of the inclined member when the design occurs, and there are holes perpendicular to the groove direction. The arrangement of the metal conductor pins enables the cantilever beam member to be level, so that the sensor has both X and Y direction induction at the same time. A sensor with another foot extending from the base end to lift the mechanical fit between the sensor and the mounting surface. The patent No. 4,3,617,740 is a seismic sensor, which is a package-shaped member. The central ring-shaped member has a conductive member arranged coaxially on a jacketed central post. Middle extended surface groove that can be inserted into the first and second contact flanges. The contact member allows the sensor to be applied in four different ways as described in the 5,8 2 3, 2 2 3 patents, one on a small plate. When the earthquake exceeds the set capacity, the beads will slide out of the small plate and fall into the middle of the pipeline to enter the effect of blocking. Not only the structure is simple and the cost is low. Adjust the shape and size of the small plate. The tilt sensor of the 4,9 7 2,5 9 5 patent is a uniaxial sensor, which improves the problem that the traditional tilt sensor is too large. The traditional tilt sensor is a long horizontal sensor, so the horizontal axis must have a valley-shaped groove, and a circle is placed on the bottom of the valley. The circle climbs up the slope and the sensor on the slope angles. This sensor can be embedded in the circuit board of a car

528876 V. Description of the invention (5) U.S. Patent Nos. 4, 3, 8, 2, 4 and 9 are mainly used for earthquake emergency interruption. The principle is to install a movable magnet rod on the outside of the pipeline to drive the steel balls in the pipeline. The front end of the magnet rod gently rests on the spring switch. When the earthquake is too large, the magnet rod slides off the spring switch, and the steel balls in the guide pipe will cut off the pipe urgently. Many of the above-mentioned patents related to seismic judgment and occlusion technology cannot make a comprehensive consideration of the occurrence of earthquakes. For example, if a vibration is emitted by a drilling machine, it is in fact a kind of noise; or, a slight earthquake has a different effect on high-rise buildings than on low-rise buildings. In addition, in the logic of earthquake judgment, the above-mentioned technology is mainly used for the acceleration parameters generated when an earthquake occurs. It also does not consider the different attributes of the earthquake comprehensively. In other words, how can we develop a set that can take into account the height factors of different floors, as well as the generation of noise to avoid misjudgment caused by external interference (the vibration frequency of an earthquake is 0 ~ 2 0 Η z); or It can also take into account the earthquake judgment methods caused by earthquake factors with different energies, etc., and then develop a device that can immediately judge and block equipment such as gas and electrical equipment when an earthquake occurs, which has become an important research direction. . [Objective and Summary of the Invention] In view of the problems of the above-mentioned conventional technologies, an object of the present invention is to provide a method for judging strong earthquakes, so as to establish a method for analyzing changes in seismic acceleration waveforms and judging strong earthquakes. Another object of the present invention is to provide a method and a device for judging a strong earthquake, which are used to improve the shortcomings of the traditional On-Of f earthquake sensor and the method for judging a strong earthquake.

Page 8 528876 V. Description of the invention (6) Another object of the present invention is to provide a method and device for judging strong earthquakes, which can use correction parameters for high-rise buildings to eliminate the amplification effects of floor height on acceleration, speed, and displacement values. Impact, especially low frequency earthquakes. For example, when the ground surface has an acceleration of 0.2 g, there may be 0.6 g at 12 storeys. In order to achieve the above purpose, the present invention provides a method for judging a strong earthquake, according to the maximum acceleration value and vibration energy obtained when an earthquake occurs. Index data, which can calculate the acceleration threshold and energy index upper limit, middle limit and lower limit, etc., and determine whether an earthquake occurs according to the above data when a vibration occurs, including the following steps: sampling the acceleration of the vibration to obtain a maximum Acceleration value; calculating the energy of the vibration to obtain an energy value; comparing the maximum acceleration value with the acceleration threshold and the energy value and the energy index to obtain a strong earthquake judgment index; determining the occurrence of a strong earthquake according to the strong earthquake judgment index. Among them, the strong earthquake judgment index can be obtained according to the following criteria: When the measured maximum acceleration is greater than the upper limit of the acceleration threshold and the energy value is greater than the lower limit of the energy index, the strong earthquake judgment index is given as a strong earthquake; if the energy value is less than the energy index If the lower limit is set, the strong earthquake judgment index is given that no strong earthquake has occurred; when the measured maximum acceleration is less than the upper limit of the acceleration threshold and greater than the middle threshold of the acceleration threshold, and the energy value is greater than the middle limit of the energy index, the strong earthquake determination index is given as A strong earthquake occurs; if the energy value is less than the middle limit of the energy index and greater than the lower limit, the first conditional earthquake determination is performed; if the energy value is less than the middle limit of the energy index and less than the lower limit, the strong earthquake judgment index is given as the strong earthquake has not occurred

528876 V. Explanation of the invention; and, if the energy index is less than the earthquake criterion, a limit is set and the value is increased by a fixed value, as an example; ^ In addition, if the vibration frequency is determined by a strong earthquake, it is obtained. When the safe speed shift is greater than the maximum; and, the large safety value and energy are a strong earthquake (7), and the energy is determined when the maximum upper limit is set; if the third lower limit, the conditions are the most secure, such as a hundred safe zones, but also shake The frequency is less than the occurrence of this issue, but yes, if the maximum safety is shifted, the index. In order to determine the speed of the installation, the energy value on the given index is within six domains of the full displacement of the given earthquake. Increasing its rate is greater than the low-pass filter. It is also possible to increase the rate to determine the strong displacement and the speed is small. The comparison is less than the strong earthquake limit and the magnitude is greater than the strong earthquake determination, or the maximum is ten. In other words, his judgment of the low-pass filtering frequency is based on the two most finger-breaking steps. The earthquake judgment is given by the maximum vigorous mouth velocity acceleration judgment by the middle energy finger; if the judgment can be made, the strong earthquake frequency can be set, and the regular wave frequency is used. The high speed scale can be as follows: The index is the safe speed value of the strong earthquake and the above method can be practically operated. The present invention also provides a device, which is produced according to the above judgment method. The door is planted in the middle limit and labeled as strong earthquake. If the value is less than 100% of the rated speed that can be marked as a safe speed in a safe area and a large number of values are smaller than the rated speed, such as 0, for example, if you have a force, stop the comparison and the maximum bit. If the transmission acceleration occurs at the maximum velocity, a strong earthquake occurs; the judgment index is degrees and the energy value of the maximum acceleration threshold is large; if the second condition is at the lower limit, it occurs in the quantitative index. Judgment, if the fractional ratio is a judgment value, judge the low-pass filter and vibration judgment; step. Calculate the value by shifting the index to a value greater than the maximum.

Description of the invention (8) Contains: Electricity sensing mode value; Micro-acceleration and acceleration indication signals and numbers are sent and displayed for detailed description [Based on the number of large earthquakes, including threshold number of inventions Both are helpful for birth, can be compared, and so on. First, let's do the basics. "Figure 1_ Analysis of the province's acceleration acceleration power supply module to supply the power required by the device; an acceleration group to sense the acceleration value of the vibration and calculate the energy controller module It has an earthquake sensing program for receiving the upper degree value, and comparing the maximum acceleration threshold value and the vibration energy index value with the energy value to determine the occurrence of a strong earthquake, and sends an alarm and a status signal; an alarm output module, It is used for receiving the warning signal alarm; and, a status display module is used for receiving the status of the status signal. The features and implementation of the present invention are shown in the figure for the best implementation example as follows: Detailed description] When an earthquake occurs ( For example, the relevant data obtained in 1982) of the Republic of China can sort out several useful parameters: maximum acceleration value, vibration energy index, exceeding the maximum speed of the acceleration gate, maximum displacement and vibration frequency, etc. ◦These six parameters establish the logic of judging the intensity of the earthquake, that is, the number of six dads measured at the vibration 'can be judged by adding the test value to the number of earthquakes. The intensity of the dynamic occurrence, and whether it is an earthquake, etc., can be judged by the occurrence of the earthquake with the maximum acceleration value of the vibration and the vibration energy. For the parameters of these two dimensions, please refer to! The seismic waveforms of a major earthquake, 900 points from 60 to 180 seconds in the measurement station, and the north-south orientation file, the characteristic distribution maps obtained. Known technology only

Page 11 528876 V. Explanation of the invention (9) The acceleration value (series, horizontal axis) is used to judge the occurrence of earthquakes. Another important parameter of strong earthquakes is often ignored, the vibration energy index (vertical axis). Because when the warehouse & volume index is high, even if the acceleration value is not large, serious injury will still be caused. Therefore, by using the above two parameters, it is possible to divide the range of occurrence of multiple strong earthquakes, that is, the first region 101, the second region 102, the third region 103, the fifth region 105, the sixth region 106, and the ninth region. 109. Secondly, in the "Figure 1", for safety reasons, some safety zones can be established in the fourth zone 104, the seventh zone 107, and the eighth zone 108, and it can be judged as a strong earthquake within the safe range. Finally, in order to exclude non-earthquake vibrations (for example, man-made vibrations), another criterion can be added, namely the frequency of vibrations. Since the frequency of an earthquake is between 0 and 2 0 Η z, any frequency greater than this frequency can be considered as interference. Moreover, the other three parameters mentioned above: the number of times that the acceleration threshold is exceeded, the maximum speed and the maximum displacement can also be used as the criterion for occurrence of strong earthquakes. In practical applications, they can be taken into consideration. Especially in high-rise buildings, the maximum velocity and maximum displacement are larger than the ground in earthquakes of the same magnitude. Therefore, the above-mentioned three parameters can be taken into consideration in determining the occurrence of strong earthquakes. The above six parameters can obtain corresponding reference values from the seismic data around the world. Therefore, the basic seismic parameters can be obtained as the standard value for judging strong earthquakes according to local conditions. As long as the reference values of seismic parameters in different places are used as a basis for comparison, the intensity and occurrence of earthquakes around the world can be judged. Next, the judgment of the occurrence of a strong earthquake of the present invention will be specifically described with reference to the drawings.

Page 12 528876 V. Description of the invention (ίο) Breaking method and judging device for occurrence of strong earthquake. First, in order to obtain the above six seismic parameters, the present invention uses an accelerometer to monitor the seismic waveform changes, and uses a microcontroller (MCU) with a built-in judgment logic program to analyze the characteristics of strong seismic waveforms. Acceleration changes, calculation and analysis of the above-mentioned various seismic characteristic parameters, and then use these six characteristic parameters to make a strong earthquake judgment. Please refer to "Figure 2", the block diagram of the module of the strong earthquake judgment device of the present invention, which includes a battery power module 20, a microcontroller module 30, an acceleration sensing module 40, and an alarm output module 50, status display module 60, and earthquake sensing program 70. Among them, the battery power module 20 provides the power required by the microcontroller module 30 and the accelerometer sensing module 40. The accelerometer sensing module 40 records the seismic waveform (acceleration change) and transmits the data. Go to the microcontroller module 30. The Microcontroller J module 3 0 reads out the built-in seismic sensing program 70 and immediately analyzes the six characteristic parameters of the seismic waveform and the reference value force α of the seismic parameter in the module to compare and determine whether the earthquake Occurs and sends the result to the status display module 60 or the alarm output module 50. Among them, the microcontroller module 30 includes a microcontroller (MCU), a seismic sensing program 70, and a memory unit for recording seismic reference parameters; while the status display module 60 can use a liquid crystal display or a seven-segment display; an alarm The output module 50 can use the buzzer. Or output a signal to an external device for safety measures such as turning off the power. The seismic sensing program 70 mainly includes several functions: reset function 7 1. temperature compensation function 7 2. detection function 7 3. filter function 7 4. high-rise building correction function 7 5 and strong earthquake determination function 7 6. Please refer to "Figure 3", the strength of the invention

Page 13 528876 V. Description of the invention (11) Function block diagram of the method for judging earthquakes. The functions are as follows: Reset function 7 1: Automatic horizontal zero correction after installation. This strong earthquake judgment device may be slightly inclined when installed. If the inclination angle is within the allowable range, the reset function will average the gravity acceleration value for a long time, and use the average value as the zero value of acceleration to automatically do the level return to zero. Amended. Temperature compensation function 7 2: Eliminate the influence of temperature on the reading of the acceleration sensor. The reading of the accelerometer will slightly shift with temperature, so the acceleration reference zero will be updated as the temperature changes to compensate for the effect of temperature. Detecting function 7 3: The function of detecting tilt. If the tilt angle is too large, the device will be judged to tilt and an alarm will be issued. Filter function 7 4: Eliminate noise, eliminate high frequency vibration, shock and other factors caused by misjudgment of earthquake. High-rise building correction function 7 5: Exclude the amplification effect of high-rise building on acceleration value. Strong earthquake determination function 76: Analyze various seismic characteristic parameters to confirm the occurrence of earthquakes. By achieving the above functions, the present invention can successfully detect the occurrence of a strong earthquake. Among them, the reset function 7; 1, the temperature compensation function 7 2 and the detection function 7 3 are completed before the vibration occurs, and the other three functions operate when the vibration occurs. Next, the method of judging the strong earthquake of the present invention and how the filtering function 7 4, the high-rise building correction function 7 5 and the strong earthquake judging power warehouse & 76 will be described through the actual operation process of the present invention. To determine whether a strong earthquake has occurred, first, capture a set time frame

Page 14 528876 V. Explanation of the invention (12) The acceleration is changed to 4 daggers, and various seismic characteristic parameters are calculated and analyzed; then, the earthquake determination method of the present invention can be used to judge the occurrence of strong earthquakes. Please refer to "Fig. 4". The present invention acquires a flow chart of seismic parameters when a vibration occurs. First, set a lower sampling rate (step 801); then, take a sample of the acceleration value and set the corrected acceleration value according to the floor height setting (step 802), and check whether the sampling value is greater than the acceleration threshold (step 803) If it is not, continue to use the 4 氐 sampling rate to capture the next point of acceleration; if it is, then open the sampling time box L and set a higher sampling rate (step 8 0 4), and start calculation and analysis of acceleration changes. At the same time, T 0 is started (step 8 0 5). The above is the realization of the filtering function 74 and the tall building correction function 75. After each acceleration value is retrieved, after the acceleration value is corrected according to the building height setting (step 806), the following actions will be performed: (1) Check whether the acceleration value A exceeds the acceleration threshold (step 807), and if yes, accumulate The number of times the sampled part exceeded the acceleration threshold (step 8 0 8) ◦ (2) Check whether the acceleration value A has undergone positive and negative changes (if the positive value becomes negative or changes from negative value to positive value) (step 8 0 9), If yes, accumulate the number of positive and negative changes in the acceleration waveform (step 8 1 0). (3) Calculate speed V (step 8 1 1), check whether speed V is the maximum speed (step 8 1 2), and if yes, update the maximum speed record (step 8 1 3).

Page 15 528876 V. Description of the invention (13) Repeatedly extract and analyze the change in acceleration until the time frame length ends (this is step 8 1 8). At the end, the six characteristics of the seismic waveform in the time frame will be obtained. The maximum acceleration value (obtained from step 8 0), the acceleration exceeding the sample number (obtained from step 8 0 8), and the maximum velocity (from step 8 8ΐι ~ 813 & get) the largest #bit private (obtained from step 8 1 4 ~ 8 1 6), vibration energy index (obtained from step 817) and vibration frequency (obtained from step 8).

After taking the characteristic parameters of the 彳 inch / item, you can perform the comparison with the seismic reference parameters. 'Please refer to "Figure 5". The strong earthquake determination flowchart of the present invention includes the following steps. · First, From the acceleration change in the time frame = the obtained seismic characteristic parameters, when A> AthreshQld (the acceleration value is greater than the acceleration two gate $ value), the seismic waveform characteristic parameters are obtained (step 9101). Next, determine the non-high frequency and impact noise (step 902). If it is noise, go back to step 1. If it is not noise, first determine whether the maximum speed is greater than the maximum speed limit (step 9). 3) If the number of times the threshold is exceeded is greater than the lower limit (step, then it is determined to be earthquake (step 905). Among them, the determination of noise is transparent ^; the wave state is considered to be realized, as described in the above-mentioned strong earthquake determination device .

On the contrary, if the maximum speed is not greater than the safe upper limit of the speed or the number of people exceeding the f1 f is not greater than the lower limit, then it is determined whether the maximum displacement is greater than the displacement safety (step 906). If the maximum displacement is greater than the displacement safety on-line, judge the number of times exceeding the threshold is greater than the lower limit (step 9G7), if yes, judge it (step 905); if not, proceed to the next step, that is, the judgement table is large Whether the acceleration is greater than the upper limit of acceleration (step 908). If the maximum Λ ϋ speed is greater than the upper limit of acceleration, it is determined whether the energy index is greater than the following steps 9 G 9). If the energy index is greater than the lower limit, it is determined as a strong earthquake (y

528876 V. Description of the invention (14) Step 9 0 5); If the energy index is not greater than the lower limit, it is judged as a non-strong earthquake (step 9 1 9). If the maximum acceleration is not greater than the upper limit of acceleration, a determination is made as to whether the maximum acceleration is greater than the middle limit of acceleration (step 9 1 0). In step 910, if the maximum acceleration is greater than the middle acceleration limit, determine whether the energy index is greater than the middle limit (step 9 1 1); if the energy index is greater than the middle limit, determine as a strong earthquake (step 9 0 5); if the energy index If the energy index is not greater than the middle limit, it is determined whether the energy index is greater than the lower limit (step 9 1 2). In step 9 1 2, if the energy index is greater than the lower limit, a conditional earthquake determination is performed (step 9 1 3); if the energy index is not greater than the lower limit, it is determined to be a non-strong earthquake (step 9 1 9). In step 9 1 0, if the maximum acceleration is not greater than the middle limit of acceleration, it is determined whether the energy index is greater than the upper limit (step 9 1 4), and if it is, it is determined as a strong earthquake (step 9 0 5); if not, proceed to Determine whether the energy index is greater than the middle limit (step 9 1 5). In step 9Η, if the energy index is greater than the middle limit, conditional earthquake determination 2 is performed (step 9 1 6); if the energy index is not greater than the middle limit, then it is determined whether the energy index is greater than the lower limit (step 9 1 7). In step 9 1 7, if the energy index is greater than the lower limit, Bayer performs conditional earthquake determination 3 (step 9 1 8); if the energy index is not greater than the lower limit, it is determined to be a non-strong earthquake (step 9 1 9). To organize the above-mentioned strong earthquake judgment process, first, first check whether the maximum speed and maximum displacement exceed the set safety upper limit. If it is and the lower limit of the acceleration threshold is exceeded, it is judged that a strong earthquake occurs (step 9 0 3 ~ 9 0 4, 9 0 6 to 9 0 7); if not, continue the judgment process. According to the magnitude of the maximum acceleration value, it can be determined in three parts: (1) The maximum acceleration is greater than the set acceleration limit: check the average

Page 17 528876 V. Description of the invention (15) Whether the vibration energy is greater than the lower limit of the set energy, if yes, it is judged that a strong earthquake occurs; if not, it is judged that a non-strong earthquake occurs (steps 9 0 8 to 9 0 9). (2) The maximum acceleration is greater than the set acceleration limit: According to the size of the average vibration energy, it can be determined in three parts (step 9 1 0 ~ 9 1 3) ·· (2. 1) The average vibration energy is greater than the set energy The middle limit was judged to be a strong earthquake. (2.2) If the average vibration energy is greater than the lower limit of the set energy, the conditional strong earthquake judgment 1 is performed. (2.3) If the average vibration energy is less than the lower energy limit, it is judged that a non-strong earthquake occurs. (3) The maximum acceleration is greater than the set lower limit of acceleration, and it can be determined in four parts according to the average vibration energy (step 9 1 4 ~ 9 1 8): (3.1.) The average vibration energy is greater than the set upper energy limit ' For strong earthquakes. (3.2) If the average vibration energy is greater than the set energy limit, the conditional strong earthquake judgment 2 is performed. (3. 3) If the average vibration energy is greater than the lower limit of the set energy, conditional strong earthquake judgment III is performed. (3.4) If the average vibration energy is less than the lower energy limit, it is judged that a non-strong earthquake occurs. In fact, the criteria for the determination of strong earthquakes in steps 9 0 to 9 1 8 are based on the area divided by the "Figure 1", that is, the relationship between the maximum acceleration and the average vibration energy is used to make the determination. Among them, the third area 10 3, the sixth area 106, and the ninth area 10 9 are of course strong earthquake areas, which are also determined based on the acceleration of the conventional technology.

The conditions of conditional earthquake determination 1 are the eighth area 10 8 in the "Figure 1", but set up A safe area determination, that is, a determination condition is added to determine whether the maximum displacement Dm ax is greater than the safe displacement upper limit D 1 imit (step 9 1 3 a) of a rated percentage m, for example, sixty percent. Conditional earthquakes The condition of decision 2 is the fourth zone 1 0 4 in the "picture 1".
