Description

DETAILED DESCRIPTION OF THE INVENTION α) Confronting field of the invention In order to notify the downstream area of a rise in water level prior to the discharge of water from a dam, the master station uses a discharge alarm control device having a combiator to notify the upstream slave stations of the rising water level. This invention relates to a discharge alarm control system which enables overlapping operations of a plurality of sequential controls, and relates to a discharge alarm system in which alarms are issued sequentially from warning devices of downstream slave stations.

(Oi) Technical Background When a dam releases water, alarm devices are installed at slave stations installed at intervals of several hundred meters to several meters to notify residents of rising water levels in the downstream area, and the master station releases water. Approximately 30 minutes before the water level rises, a speaker, siren,
A warning is issued on a display device, etc. The speed at which water flows changes depending on the amount of water discharged here. For this reason, the master station installed at the dam has several types of discharge amounts, and depending on the discharge, a table of control items such as the time of alarm issuance of each slave station and siren, speaker, etc., is set based on the master station. have. In general dams, the scenery rarely changes during discharge, but when water is used for power generation, the amount of water used changes depending on the amount of electricity required, so the water that is initially discharged changes. The discharge amount may be increased before it reaches the most downstream slave station.

The invention relates to this case.

(3) Prior art and problems Figure 1 shows a conceptual diagram of a discharge alarm system. -8 is alarm device, 6-1.6-2
indicates a siren, 7-1 to 7-8 indicate speakers, and ANH indicates a slave station name.

Issue a discharge alarm from the master station (command the discharge amount and activation from the console 2, send a control signal wirelessly (or wired) from the discharge alarm control device 1, and send the discharge alarm several hundred meters downstream. Alarm devices 5-1 to 5 of slave stations A to H installed at several intervals from
-6 is activated, siren 6-1~6-2, speaker 7
-1 to 7-8 can be moved to notify the rising water level. To notify residents, a rotating light ◆ may also be turned on, and sirens may also be placed on all subsidiary stations. At this time, write a map of the downstream area and the installation locations of the slave stations A-H on the display device 3, display the alarm issuance status with a return signal, etc. to confirm the issuance of the alarm, and also display the activation time of the master station. , the issuing time of the slave station, etc. are recorded by a typewriter 4. In the conventional example, the combination read-only memory in the discharge alarm control device 1 stores the alarm issuance time interval and each slave station's alarm issuing time interval based on the master station according to several predetermined discharge amounts. It has a table of control items for slave station speakers, sirens, and other alarm issuing devices, and when you press the discharge amount instruction button and start button from the console 2, the computer calculates the start time based on the table in the read-only memory mentioned above. Compare it with the clock in the discharge alarm control device 1 as a reference, and if the alarm issuing time += is reached, the alarm devices 5-1 to 5-8 of the downstream slave stations are operated sequentially from the upstream slave station, and the siren 6 is activated. -1 to 6-2 and speakers 7-1 to 7-8 are activated. However, with this method, only one sequential control can be operated. Therefore, if there is additional discharge, switch to manual mode and check the table of alarm issuing times for each slave station based on the master station according to the discharge amount. However, when the alarm issuance time comes, the alarm is issued at each slave station one after another by pressing the button for the name of the slave station, the start button, and the button for the control item (tape broadcast siren, etc.) using the operation 42.

In addition, if the discharge amount at the time of additional discharge is greater than the previous discharge amount,
A slave station with water released later may overtake the water released earlier, so the difference between the alarm issuance time for each slave station due to the water released earlier and the time the alarm is issued for water released later is not constant. It's complicated. Therefore, it is time-consuming and may lead to operational errors.

(4) Object of the Invention An object of the present invention is to provide a discharge alarm device that is capable of automatically performing a plurality of sequential control operations at the same time in order to eliminate the above-mentioned drawbacks.

(5) Structure of the Invention: By controlling the discharge alarm control value with the computer of the master station,
In a discharge alarm system that issues an alarm from an upstream slave station to a downstream slave station's alarm device, when the discharge alarm control device starts issuing an alarm, the predetermined amount of water to be discharged at this time. Create a table showing the time to issue an alarm at each slave station by adding the time interval between the master station and the six slave stations according to the control items, and if the table has been created first, the alarm will be issued. When the alarm issuance time of a slave station due to the earlier activation has caught up with the alarm issuance time of a later activation, the alarm issuance time of the downstream slave station is as follows. A table creation program that creates a table with the alarm activation time that was activated by him,
A control program is provided that controls the issuance of an alarm to each slave station in accordance with the control contents according to the order of the table, and a table created by the table creation program described above is provided when the discharge alarm control device is activated. This discharge alarm control device is characterized in that each slave station issues an alarm under the control of a control program according to the alarm issuing time and control items.

(6) Examples of the invention An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a graph showing the relationship between alarm issuing time and slave stations when two sequential operations overlap. FIG. 3 is a diagram showing a table on the main storage device in the case of the first sequential operation shown in FIG. 2a in the case of FIG. 1 of the embodiment of the present invention, and FIG. Fig. 2 for the example shown in Fig. 1 is a diagram showing a table on the main memory in the case of the second sequential operation already shown.◎A-H in the figure indicates the names of slave stations, and station A is Located close to the main station, tape broadcasts and sirens are broadcast over loudspeakers.
shall be carried out. The example in Figure 1 will be cited for the method of notifying residents using other slave stations. Further, in the example of FIG. 2, for the sake of explanation, the alarm issuance intervals of the slave stations are equal, but they do not have to be equal.

If water is to be released around 6:30 at the amount shown in Figure 2, the alarm will be issued at the slave station at 6:00.

In this case, Combi Island in the discharge alarm control device 1 - Yu is by the table creation program! As shown in FIG. 3, memory address 0001 on the main memory of the discharge alarm control device 1 of FIG.
~0010, the slave station name ANH corresponding to the startup time of 6 o'clock and the control item..., taking into account the alarm issuance time interval of each slave station A to H, and store the control contents in order of earliest alarm issuance time. The time is compared with the clock in the discharge alarm device 1 in the order of memory addresses 0001 to 0010 of this stored content, and the control program causes the alarm devices 5-1 to 5-8 of each slave station A-H to be activated when it is time to issue an alarm. Depending on the control item, the content of the tape transmitted from the discharge alarm control device 1 of the master station is broadcast on the speakers 7-1 to 7-8, or the siren 6-1.6 is activated.
-2 will be blown to notify residents of the rising water level. Next, at around 7:30 a.m., if a larger amount of water is to be released than what was released earlier, the alarm will be activated at 7:30. This causes the table creation program to be started by interrupt. If a table like the one shown in Figure 3 had been created earlier, this water would have been created by comparing the first and second alarm issuing times and sorting them in descending order. When the second alarm issuance time catches up with the alarm issuance time at the slave station Toru, the slave station G downstream from this.

H is designed to create a table that is controlled based on the second alarm issuing time, so by controlling the combination in the discharge alarm system ML, the second starting time is 7 o'clock. The slave station names A-H and control items corresponding to this discharge amount, the alarm issuing times of each slave station A-H taking into account the alarm issuing time interval of each slave station A-H, and the first Compare the alarm issuing times for the first time, change the alarm issuing time from the earliest to the next, and change the memory address 0001-0012 on the main memory of the discharge alarm device 1 to 7 o'clock as the initial value to generate an alarm as shown in Fig. 4. Stores a table of issue time, slave station name, and control items. In the evening, the discharge alarm control device 1 compares the alarm issuing time with the clock in the discharge alarm control device 1, and according to the control program, the discharge alarm control device 1 stores the memory addresses 0001 to 0012 in the order of the alarm issuing time. Depending on the station and control items, the slave station alarm device B-
Activate steps 1 to 5-8 to issue an alarm.

Since slave stations A, B, and O have already issued their first alarm at 7 o'clock, the table in Figure 4 shows [Slave stations A, B, and O show the second alarm. Also, after station O, the amount of water is the sum of the water released in the first time and the water released in the second time, and flows all at once, so only one amount of water is shown. Of course, if the water from the second pewter discharge does not overtake the water from the first discharge, a discharge alarm will be issued twice.

By doing so, a plurality of overlapping sequential control operations can be performed by a human operator simply by pressing the discharge amount setting switch and start switch on the console 2.

Furthermore, it is also possible to configure a fully automatic system by receiving commands for setting and starting the discharge amount from the dam gate automatic control system.

(η) Effects of the Invention As explained in detail above, according to the present invention, multiple sequential control operations can be automatically performed by simply instructing the discharge amount and start-up time, which is advantageous in that it does not require much effort and can prevent operational errors.
