Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a gate control system for controlling the opening and closing of a water discharge gate of a dam or the like.

(Prior Art) Conventionally, this type of gate control system has two processing devices 1 and 2, as shown in FIG. During normal operation, actual measurement data such as the water level and opening degree obtained from the water level needle 3 and the gate opening meter 41 of the gate 4 is input to the processing device 1 via the input/output control device 5, and the processing device 1 imports the measured data. Calculate the discharge amount, inflow amount, etc. from the actual measurement data,
The calculation results are supplied to the gate operation console 6. The operator opens and closes the gate while looking at the display on the gate operation console 6. The processing device 1 performs gate control not only during the above-mentioned normal times but also during actual floods, and at this time the processing device 2 is in a standby state. Incidentally, when calculating the above-mentioned discharge amount and inflow amount, the processing device 1 retrieves and uses the program management data (conditions and rules regarding gate opening/closing) for calculation from the magnetic disk 7, and also uses the input/output control device. Actual measurement data taken in via 5 is stored.

On the other hand, when conducting a mock test, switch the changeover switches 8 and 9 shown in Figure 4 to the terminal side, input the actual measurement data to the processing device 2 side, and make the opening/closing control backup of the gate 4 equivalent to that of the processing device 1. The processing device 2 having a processing capacity of Instead, the processing device 1 includes a mock test device 10.
A mock test was conducted by inputting information from the gate operator and in combination with the gate operation console 6. However, in order to conduct a mock test using the conventional system, it is necessary to have duplex equipment using two processing devices 1 and 2, which has the disadvantage of increasing the system price and making it difficult to introduce. Rarely.

Also, while the mock test is running, the gate operation console 6 will be moved into the mock test system, making it impossible to operate the actual gate, so the mock test should only be conducted on days with good weather conditions and stable weather. The disadvantage is that it is rarely possible.

(Problem to be solved by the invention) In the conventional gate control system mentioned above, in order to conduct a mock test, the processing equipment must be duplicated, making the system expensive and difficult to introduce. There were drawbacks. Furthermore, since it is not possible to perform actual gate operations during the mock test, the test must be conducted on days with good weather conditions, resulting in restrictions on the timing of the test. Therefore, the present invention aims to eliminate the above-mentioned drawbacks, and aims to provide a gate control system that can perform simulation tests independently of the original gate control regardless of weather conditions and has a low system cost. It is said that

[Structure of the Invention] (Means for Solving the Problem) The present invention performs opening/closing control of a discharge gate of a reservoir, and simulates opening/closing control of the discharge gate to conduct a simulation test of the water level, discharge amount, etc. of the reservoir. The discharge gate control system is equipped with a processing device that inputs the water level and the gate opening degree in real time and executes the opening/closing control of the discharge gate in real time. In addition, there is a human-powered device that inputs the data necessary for conducting a mock test, a gate control simulator that executes the mock test based on the data from this input device, and a display that displays various data and mock operation results associated with the mock test. a simulation system equipped with a display device, and the simulation system has a calculation request control means for interrupting the processing device of the discharge gate control system to perform various calculation processes necessary for execution of the mock test. It has become.

(Function) In the gate control system of the present invention, the simulation-based gate control simulator executes a mock test based on data obtained from the input device, and at this time, the calculation request control means performs calculations necessary for executing the mock test. Therefore, the processing device of the discharge gate control system, which is independent from the simulation system, is requested to perform the processing. Therefore, the configuration of the gate control simulator can be made simpler and cheaper than the configuration of the processing device. In addition, the discharge gate control system can always perform gate discharge control of the reservoir simply by calculating the simulated operation using an interrupt, so a simulation test of the simulation system can be performed at any time regardless of the weather.

(Example) An example of the present invention will be described below with reference to the drawings, in which the same parts as those of the conventional example are denoted by the same reference numerals. FIG. 1 is a block diagram showing an embodiment of the gate control system of the present invention. 1 is a processing device that performs calculations related to opening/closing control of the gate 4 and calculations for simulation; 3 is a water level needle that measures the water level of the dam; 41 to 4o are gates for releasing water from the dam; 5 is data input/output control 6 is a gate operation console from which the operator gives instructions to open and close the gate; 7 is a magnetic disk that stores calculation programs, management data, actual measurement data, etc.; 11 is a gate for performing gate mock tests. Gate control simulator 1 is a control simulator device.
10. It consists of a keyboard 111 for inputting initial values of water level and gate opening degree, etc. to this simulator 110, and a CRT display device 112 for displaying interaction with the gate control simulator 110, mock test results, etc. 12 is a gate driving device 411 that drives the gates 41 to 4° to open and close them;
41 is a gate opening meter that measures the opening degree of the gates 41 to 4o. Here, the processing device described in the claims is the processing device 1 in FIG. 1, and the discharge gate control system is the first processing device.
The simulation system corresponds to the system including the processing device 1, gate console 6, input/output control device 5, etc. shown in the figure, and the simulation system corresponds to the gate control simulator @11 shown in Fig. 1. In simulator 10,
The input device corresponds to the keyboard 111 in FIG. 1, and the display device corresponds to the CRT display device 112 in FIG. The calculation request control means is the gate control simulator 10 shown in FIG.
This corresponds to the program.

Next, the operation of this embodiment will be explained. The processing device 1 takes in measured data such as water level and gate opening from the water level needle 3 and gate opening gauges 411 to 41o via the input/output control device 5, and uses this measured data to calculate the amount of inflow into the dam and from the dam. Furthermore, the target gate opening degree of the dam is calculated based on the management data at that time, and this is supplied to the gate operation console 6. The operator issues a command to open and close the gate until the target gate opening degree displayed on the gate operation console is reached, and this command is fed back to the gate opening/closing drive device 12 via the input/output control device 5 to control the opening and closing of the gate. It will be done. This discharge gate control system is always connected, and the opening/closing of the gates 41--4o is controlled in any case.

Next, the operation of the gate control simulator device 11 will be explained according to the gate control simulation operation algorithm shown in FIG. In order to operate the gate control simulator 11, time-series data of the inflow amount is input in advance into the gate control simulator 110 from the keyboard 111 as inflow amount hydro data. This corresponds to the amount of water flowing into the dam. In addition, in order to start the mock test, the starting water level Ha and the opening degrees P1 to Po of each gate are required, and these are also input in advance from the keyboard 111 to the gate control simulator 110.
Enter it and open it. In this state, the keyboard 111
The gate control simulator 11 receives a gate control start instruction from the gate control simulator 11.
When 0 is input, the gate control simulator 110 extracts the inflow amount Qi from the inflow hydrodata town indicated by A to the first dam indicated by mouth, and calculates the sum of the discharge amounts 01 to Q of each gate indicated by 8. The difference between a certain gate discharge amount Q and the inflow amount Qi is determined. At this time, the gate control simulator 110 requests the processing device 1 to perform this subtraction process by interrupt. As a result, the processing device 1 has an inflow amount Qi and an outflow amount Q.

Perform the operation to find the difference. The inflow amount Q and the discharge amount Q
The difference causes the water storage amount V and water storage level Ha to change. Therefore, the gate control simulator 110 again requests the processing device 1 to perform calculations to derive changes in the water storage tv and the water storage level Ha.

As a result, the processing device 1 changes the water storage amount V shown in △
(2) is calculated, and from this calculation result, the change ΔHa in the water storage level H shown in (e) is calculated and notified to the gate control simulator 10. Next, gate control simulator 10
is determined based on the relationship between the inflow LiQi, the gate discharge amount Q, and the storage water level Ha.The target gate opening degree (of the gates 41 to 4o) Hereinafter, it will simply be referred to as the gate opening degree.〉P1~
The processing device 1 is requested to perform arithmetic processing to obtain P by interrupt. As a result, the processing device 1 calculates the discharge IQ1 to Qo of each gate, which indicates how much water should be discharged from each gate, based on the gate control method, and further calculates the discharge IQ1 to Qo of each gate shown in G corresponding to this. The opening degrees P, ~Po are calculated and these data are output to the gate control simulator 10. For this reason, the gate control simulator 10
The gate opening degrees P1 to P0 of the gates 41 to 4o are displayed on the screen of the CRT display device 112. The operator looks at the gate opening degree ~Pn and selects the gate 41 from the keyboard 111.
A command is issued to set ~4o as the gate opening degree P1~P.

On the other hand, the processing device 1 further includes discharge amounts 01 to Q indicated by H,
is added to give the gate discharge IQ, which is used in the next step shown in 8.

Calculate. Next, the gate control simulator 10 again takes out the inflow IQi+i to the dam at the next timing from the inflow amount hydro data H'/ shown in A, and repeats the above simulation process. In the end, the gate control simulator device 11 sequentially extracts the inflow amount Qi from the inflow amount hydro data H7 according to the procedure shown above and performs a gate control simulation operation.

By the way, the gate control simulator 10 calculates not only the gate opening degree ~P mentioned in the above simulation procedure, but also the inflow amount Q. and the gate discharge amount Q.

Each time the processing device 1 calculates the six values of water level H and discharge amount 01 to Q, the CRT display device 112 is controlled to display the flood control diagram shown in FIG. 3, which is the result of a mock test. indicate. This flood control diagram shows the inflow fiQ and the gate discharge amount Q. This figure shows temporal changes in the water level Ha and water level Ha in a simulated test.Gates 41 to 4 are opened and closed in a simulated manner in response to changes in the inflow amount Q, and the gate discharge amount Q.

By changing the water level Ha as shown in the figure, the change in the water level Ha of the dam is kept within an approximately allowable range.

According to this embodiment, the gate control simulator 110 of the gate control simulator device 11 causes the processing device 1 to perform calculation processing for the mock test by interrupt, and performs the mock test processing. It can be made simple and inexpensive, and the system cost can be reduced. Moreover, since the gate control simulator 110 does not perform calculation processing as described above, the load is very light and gate control simulation test processing can be performed at high speed. or,
During a simulation test for operator training, the simulation test process can be performed in the same real time as the actual gate control performed by the processing device 1, and the execution time of the simulation can be arbitrarily specified. Further, the processing device 1 performs calculation processing requested by the gate control simulator 110 in response to an interrupt, but other than that, the processing device 1 performs calculation processing requested by the gate control simulator 110, but otherwise performs calculation processing requested by the gate control simulator 110. Since the gate control processing is performed, the simulated operation of the gate control simulator 110 can be performed independently of the actual control processing of the gates 41 to 4o, and the simulation is performed except on days when the weather is good, as in the past. This eliminates the inconvenience of not being able to do things.

[Effects of the Invention] As described above, according to the gate control system of the present invention, a mock test can be conducted independently of the original gate control regardless of weather conditions, and the system cost can be reduced. be able to.
