Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention is applicable to fire alarm equipment, gas leak alarm equipment, theft prevention equipment, etc., which are composed of a receiver and a plurality of terminal devices connected to the receiver. The present invention relates to a testing device for disaster prevention equipment, and in particular to a testing device that automatically processes test result information in order to determine abnormalities in terminals 1m3 in such disaster prevention equipment.

[Conventional technology] Conventionally, testing of terminal equipment in disaster prevention equipment has been performed from the start of the test to the processing of the collected test results by a human or operator while checking the display, determining whether to start the test, and processing the collected test results. They judged the quality of the test results, as well as the time it took for the test results to be displayed.

Problems to be Solved by the Invention According to this conventional configuration, the operator must first wait until the test results are displayed and then judge whether the time taken to display them is good or bad. Furthermore, after being properly displayed, the displayed test results are processed to determine whether or not an abnormality has occurred in the terminal equipment.
Because it relies on human judgment in this way, it is less reliable,
There was an inherent possibility that a mistake in judgment could lead to a serious accident.

Therefore, an object of the present invention is to eliminate the need for humans to wait until the test results are displayed, and to automatically process the test results of terminal equipment without relying on judgment between two people. The purpose of the present invention is to provide a testing device for disaster prevention equipment.

Means for Solving the Problems] To achieve this object, according to the present invention, a receiver connected to a plurality of terminal devices collects information from the terminal devices by a first means, In the disaster prevention equipment that discriminates various events based on the information of terminal devices collected by the first means, the second means stores unique information of a plurality of terminal devices; and a test start command. a third means for energizing a timer means and sending a test start command to each of the terminal devices based on the test result information from each of the terminal devices in accordance with the test start command; fourth means for processing the test result information collected from the terminal device based on the unique information of the second means after a predetermined time set in the timer means has elapsed; Provided is a test device for disaster prevention equipment characterized by comprising the following.

Thus, the third means activates the timer (FIG. 2; block 220) and automatically sends the test start command (FIG. 2; blocks 106a and 112); Fourth means automatically process the collected test result information (FIGS. 2 and 4; block 40).
0), the problem of operator error in judgment is eliminated.

In addition, if a timer means is used to collect test result information and process it within a predetermined time, and if an abnormality occurs, it will be automatically displayed and V-reported, so that the operator can wait until the test is finished. There's no need.

[Example code] An embodiment of the present invention will be described below.

FIG. 1 shows the present invention by taking a polling type disaster prevention equipment as an example, and in the figure, receivers R and E are connected to a plurality of terminal devices SE, that is, SRI to SEn. For convenience of explanation, terminal devices SEI to SEn are shown here.
All of these are fire detectors that send analog quantities of detected fire phenomena as digital signals to the receiving fiRE, but in reality, various types of terminal equipment required for disaster prevention, such as fire phenomena exceeding a predetermined value, are used as fire detectors. It will be understood by those skilled in the art that on/off fire detectors or repeaters that output a fire signal when a fire signal is detected may be connected together.

In the receiver RE, the CPU is a microcomputer, ROM] ~ ROM3 is a read-only memory, and ROM1 is used for polling terminal equipment and determining whether the received signal is test result information or fire information. , a program for determining whether a fire has occurred based on fire information and displaying the result, and for analyzing test results from test result information is stored in ROM2, which is used when executing the program in ROM1. Discrimination reference values for each terminal device, that is, fire discrimination values, test start tolerance values, test result discrimination values, etc., are stored in the ROM3, and the addresses of the connected fire detectors SE1 to SEn are stored in the ROM3. A terminal map indicating the sensor type and its type, such as heat sensor, smoke sensor, gas sensor, etc., is stored. TMI is the test timer used during the test, DP is the display section equipped with indicators such as a fire area display window or CRT display, and various lamps, and OP is the terminal with various switches such as the sound stop switch and recovery switch. This is a scratching section provided with a test switch SW, a terminal selection switch, etc. RAM1 and RAM2 are random access memories;
M1 is used for polling and various types of discrimination, and R
AM2 is used to store status information received from each terminal device. TR is a transmitting/receiving section having a serial/parallel conversion circuit, a transmitting circuit, and a receiving circuit.

The analog fire detectors SE1 to SEn have similar internal configurations, so the details of the configuration are shown representatively only for SE1.

In the fire detector SEL, the CPU is a microcomputer, the FD is a heat type or smoke type fire detection unit, and the ADC.
is an analog-to-digital converter that converts the analog quantity signal output from the fire detection section FD into a digital signal, and in this case, the fire detection section FD and the analog-to-digital converter ADC function as the abnormal phenomenon detection section. It consists of TC is a test circuit that is a part of the test means, and if the fire detection unit FD is a thermal type having a thermistor, for example, 9
A heater or the like is provided to heat the thermistor to a predetermined temperature. ROM21 is a read-only memory that stores programs, RAM21 and RAM22 are random access memories, RAM21 is used for work, and RAM22 is used to store the AD-converted fire detection section immediately before the test starts. Used to store the detection output of the FD. TM21 is a timer that is started at the start and end of the test, and the operating time is, for example, when the fire detection unit FD is a thermal type of thermistor and the test circuit TC has a heater, the timer is activated by the heater at the start of the test. The time required for the output of the heated thermistor to stabilize, and the time required for the output of the thermistor to stabilize after the heater stops heating the thermistor at the end of the test are each set to be slightly longer. TR is a transmitting/receiving section, and has the same configuration as that of the receiver RE.

Next, the operation of the present invention will be explained using the flowcharts shown in FIGS. 2 to 6.

First, the operation during normal fire monitoring will be explained with reference to FIG.

The CPU of the receiver RE performs an operation of polling the terminal devices SE1 to SEn in order. Block 10 where the nth fire detector is set to be polled.
2> The determinations in blocks 103 to 107 following @ are all "No" during normal fire monitoring, so a control command is created for terminal No. 0 by checking the work RAMI in block 108. It is determined whether it is necessary to do so. If the fact that a control request has been issued to terminal No. 0 during polling operation is not stored in the working RAM 1, a normal status information request command code is created after block 109), and if it is stored again. After creating the corresponding control command code (block 110), erasing the corresponding terminal number n in RAM1 (block 111), adding address code 0 to the command code and sending it to the signal line (block 112).

When the status information in response to the sent instruction code is received from the terminal device No. 0, it is sent as the status information! (block 113) and determines whether there is a test result code (T flag) in the status information (block 114). . In this case, since this is normal status monitoring operation and not test operation, the T flag does not exist, so the ROM 3 is then referred to and the status information is the signal from the sensor (block 115). , it is determined whether the signal is from a sensor (block 116), and if it is a sensor, the fire discrimination value corresponding to the sensor is read out from the ROM 2 (block 117), and it is compared with the status information to determine the fire discrimination value. It is determined whether there is a fire or not by determining whether or not the above is the case (block 118).If it is a detector, it is determined whether there is a fire signal in the status information or not (block 119). Display the fire area, perform main/area sound processing, etc. (Block 1)
20).

Here, the term "sensor" refers to a type of fire detector that outputs an analog quantity, and it is possible to obtain various status information based on the analog quantity. This refers to something that only outputs an on/off signal.

If it is not a sensor or a detector, but the status information of the terminal, for example, if the control circuit of a repeater is operating, it is decoded and the status of the terminal is displayed. (block 121). Thereafter, through blocks 122, 123 and 102, the process moves to polling for the next terminal number.

In addition, in blocks 120 and 121, if there is a terminal to be controlled in relation to it, its terminal number and control contents (commands) are stored in RAM 1, so that when the next n-th terminal is polled, the required information is executed in block 108. Control is determined, and a control command code is sent to the nth terminal (block 1
10, ]11, and 112).

Next, the operation during the test will be explained.

Test start switch provided on the operation unit OP (not shown)
is operated, a test start interrupt occurs (“YES” in block 103), and the process goes to the test start processing program 200.
The details of 0 are shown in the flowchart of FIG.

Note that the test shown here is started by a human operating the test start switch, but the test can be started automatically, for example once a day or once a week. It is also possible to generate an interrupt, and even in such a case where an interrupt is automatically generated, the determination in block 103 is YES.

In the flowchart shown in FIG. 3, k is used instead of H as the general terminal number of N terminal devices. First, referring to the contents of ROM3, it is determined whether or not the k-th terminal is the test target (block 2
03). Here, since the device to be tested is a repeater connected to an analog sensor or a fire detector, other terminal devices are excluded from the test object.

If the k-th terminal is not the terminal device to be tested, the process goes through decision blocks 210 and 202 to determine whether the next terminal is the terminal to be tested, and if it is the terminal to be tested, then the Read the status information of the terminal (block 204), if it is a sensor, read the status information of the terminal
Block 206) reads out the test start tolerance value of terminal No. 2 from R, OM 2), and reads out the status information of terminal No. 2 from RAM 2, that is, the fire phenomenon detected by the fire detection unit FD. The analog amount is ROM2
(block 207).

Here, the test start tolerance value is set to a value between the reference value at which it is determined that a fire has occurred and the value under normal conditions. It is set to a value such that it is too early to do so, but testing should be aborted.

If the determination in block 205 is that it is not a sensor, it is a sensor, so a determination is made as to whether or not it is in a fire signal state (block 208). Here, the fire signal state is defined as if there is a fire signal in the status information. , that is, state 3 is when the storage circuit or storage timer is operating when it is on or in response to a fire signal.

If the determination in block 207 is below the allowable value, or if the determination in block 208 is not in the fire signal state, k
R as the test start terminal that is allowed to start the test.
After storing in AM1 (block 209), a similar determination is made in block 203 for the next terminal number. In this way, when it is determined that all the test target terminals are test start terminals (YES in block 210), block 211
), the test timer TMI is turned on, and the test start interrupt caused by the test start switch is canceled (block 220), thereby terminating the test start processing program.

If there is even one terminal for which the determination in block 207 is greater than the allowable value or the determination in block 208 is in a fire signal state, such a terminal is discovered in order to prevent the terminal test from being performed. Block 2 to erase all the numbers of test starting terminals stored in RAM 1 up to this point.
12) Display on the display unit DP that the test start is not accepted; block 213); cancel the test start interrupt caused by the test start switch on the operation unit and end the test start processing program.

If the test start processing program determines that the test can be started, the process returns to FIG. 2 and returns to the polling operation from block 102.

Since the test start interrupt has been canceled, the determination in block 103 is No. Next, it is determined whether or not a test end interrupt has been performed (block 104). This test end interrupt is used when you want to forcefully end the test.
This occurs by operating the test end switch provided in the processing section.

When a test end interrupt occurs, the process goes to the test end processing program 300, and this test end processing program 300
The details are shown in the flowchart of FIG. In this test completion processing program 300, all terminals to be tested (blocks 303 and 305) are stored in RAM 1 as test completion terminals (block 304).
, turn off the test indicator light turned on in block 2]-1 of FIG. 3 (block 306), cancel the test end interrupt, and then return to FIG. timer TM1 (block 132 in FIG. 2). As a result, the determination in block 107 will be Y during the next polling operation during normal fire monitoring.
ES, a test end command code is created in block 107a, and the test end command is sent to each terminal device (blocks 111 and 112).

If no test end interrupt occurs (block 1
No. 04) Next, it is determined whether the test timer TM1 is in operation (block 1.05), and since the test timer TMI is turned on in block 220,
Next, in block 130, it is determined whether the time measured by the test timer T M 1 has reached a predetermined time. Since the predetermined time has not yet passed, the process goes to block 106, where T'(
AM ] is stored as a test start terminal. The device in question is RAMI as the test start device.
If the address code is registered in block 111), you want to create a test start instruction code.After block 106a), erase the memory of the test start required for the terminal number in RAMI.Add the address code to the instruction code and write it to the signal line. Send directly.

After that, the terminal starts the test operation in response to the test start command, and the corresponding reply information from the terminal is r(
AM 2 is stored in the corresponding address area (block 1
13). On the receiver side, it is determined whether the stored information has a T flag indicating that it is test information (block 114), and if there is a T flag, nothing is done here and polling is performed for the next terminal number. (block 122 and], 02). Then test timer TM
When the clock time at I passes a predetermined time (block 13
0 (YES), then the test result processing program 400 will be executed based on the test information collected from the terminal into the RAM 2.
The details are shown in the flowchart of FIG.

Note that the predetermined time in block 130 is set to be longer than the time necessary for all terminals to be in a state where they can send stable trial @fi information.

Also, during this predetermined time period, as described below, information from the same terminal may be collected multiple times, so the terminal is configured to send out test information at the time of collection.

In the test result processing program shown in FIG. 4, it is determined based on the contents of ROM 3 whether or not terminal k is the terminal to be tested (block 403), and if it is not the terminal to be tested, the same determination is made for the next terminal. Move. If it is the terminal to be tested, the status information of the k-th terminal is read from the RAM 2 (block 404), and then it is determined whether or not there is a T flag in the information. Without the T flag,
Block 406) to store in RAM 1 that the k-th terminal has not responded in the test; block 407) to turn on the indicator light corresponding to the terminal that has not responded to the test, that is, the test non-responsive terminal indicator light; The process moves on to the determination in block 403 for the terminal.

In the determination of block 405, if the T flag is present, R
Referring to the contents of OM3, it is determined whether the corresponding terminal is a sensor (block 408).

If it is not a sensor, it is a sensor, so a determination is made as to whether the test result was normal, that is, whether or not the on signal was normally output as a result of the test (block 409).
). If it is a sensor, then the upper limit and lower limit values for determining the test result of the second terminal are read out from ROM2 (block 41o), and the sensor state information at the time of the test read out from RAM2 is read out. A determination is made as to whether the output of the phenomenon detector is within these reference values (block 411).

If the determination in block 409 is normal or the determination in block 411 is within the reference value range, the terminal is determined to be normal as a test result;
If the determination of 09 is abnormal or the determination of block 411 is outside the reference value range, that terminal is determined to be abnormal as a test result, and the fact that the kth terminal is abnormal is stored in RAMI (block 412). At the same time, the abnormal terminal indicator light on the display section DP is turned on (block 413), and then the process moves to test result determination for the next terminal.

Note that the test non-responsive terminal indicator light in block 407;
The abnormal terminal indicator light in block 413 can also be used as a terminal failure indicator light.

When the test results for all terminals have been determined in this way (YES in block 414), the process goes to test completion processing program 415. This test completion processing program 415 is the same as the test completion processing program 300 shown in FIGS. 1 and 5. That is, blocks 303 and 305) that are attached to all test target terminals, block 304) that is stored in RAM 1 as a test-required terminal,
The testing indicator light on the display section that was turned on in block 211 of FIG. 3 is turned off (block 306). Then the fourth
Returning to the figure, after printing the abnormal terminal number and test non-response terminal number stored in RAM1 in blocks 406 and 412, and making an abnormal sound (block 416), the abnormal terminal number and test non-response terminal number stored in RAM1 are printed. Delete the test non-responsive terminal number (block 417).

After that, the test timer TMI is cleared (block 1
32), return to normal fire monitoring operation.

Finally, the operation related to the test of a terminal device suitable for use in the disaster prevention equipment of the present invention will be explained with reference to the flowchart of FIG. 6, taking a sensor, that is, an analog type sensor, as an example. However, the terminal device is not limited to the one shown in FIG. 6, and various other devices can be used.

A test start interrupt occurs on the receiver side (block 103 in Figure 2), a test start command code is created (block 106a in Figure 2), and the command code is sent to the signal line (block 103 in Figure 2). Block 112), when the address is received by the terminal device, the terminal device determines whether it matches its own address stored in the ROM 21, for example (block 502), and if it matches, then , decodes the received command code, and determines whether it is a wall block 503) which is a test start command or a wall block 504) which is a test end command. Since this is a test start command, next, in order to store the detection output immediately before the test starts, the detection output of the fire detection unit FD is stored in the RAM 22.
(block 505), and the test circuit TC and timer T M 21 are turned on (block 506).
). When the test circuit is turned on, a heater or the like heats the fire detection section FD, for example, in order to test whether the fire detection section equipped with a thermistor detects a fire normally. Thereafter, the detection output stored in the RAM 22 is read out and sent to the signal line (block 507).

The next instruction code transmitted from the receiver is the status information request instruction code created in block 10 of FIG. This is because the test start interrupt has already been cleared as described in block 211 of FIG. As a result, the determinations in blocks 503 and 504 are both NO, and since the timer TM21 is still operating (YES in block 508), the terminal device again sends out the detection output of the fire detection unit FD stored in the RAM 22. This happens (block 507).

The terminal equipment that received the test start command in this way starts the timer T.
While M21 is operating, the detection output of RAM22 is sent out,
This transmits the detection output immediately before the test starts until the transient and unstable detection output of the fire detection unit FD at the start of the test stabilizes, thereby preventing incorrect judgment on the receiver side. It's for a reason. Therefore, the set time of timer TM21 is the fire detection section r? The time is set to be slightly longer than the time required for D to stabilize.

When the timer TM21 times up, the next status information request command code sent from the receiver is block 50.
8, it is determined whether the test is in progress or not in block 50. Since the test is in progress, that is, the test circuit is on, the status information at the time of the test is sent to the detection output of the fire detection unit FD. A T flag is added to indicate that the test information is present, and the test information is sent to the signal line, and stable test information is sent back to the receiver. Similarly, this same detection output with the T flag added is returned.

After that, a predetermined period of time has elapsed on the receiver side (block 130 of the second country), the test result processing program 400 is executed, and the test end command code created in block 107a is transmitted from the receiver side. Y of special block 504
ES), the test circuit is turned off, timer TM21 is turned on (block 511), and in block 505 the RA
The detection output immediately before the start of the test stored in M22 is sent to the signal line (block 507).

Next, when a status information request command code is transmitted from the receiver side, if the timer TM21 is operating, the contents of the RAM 22 are similarly returned via YES in block 508, and the timer TM21 is turned off. Then, the normal monitoring operation is resumed and the detection output of the fire detection section is sent out (block 512).

[Effects of the Invention] As described above, according to the present invention, based on the test start command, the timer means is energized, the test start command is automatically sent out, and the test result information collected from the terminal equipment is transmitted. Since the process is performed automatically, it has the effect of eliminating judgment errors by the operator. In addition, a timer means is used to collect test result information and process it within a predetermined time, and in the event of an abnormality, it is automatically displayed and alarmed, so there is no need for the operator to wait until the test is completed. It also has the effect of not having any.
