Description

  The present invention relates to a gate control device that controls a gate of a dam, and more particularly, to a gate control device that enables a target opening to be changed during a gate opening adjustment operation.

  A conventional gate control device has a target opening table that associates a gate number (gate designation information) assigned to each gate with a target opening degree for each operation such as the first time and the second time. An operation order table in which numbers are arranged is held, and when a gate operation request is given from the operation terminal, target opening for each operation specified in the target opening table in the order of gate numbers specified in the operation order table is performed. The control command corresponding to the target opening is given to the drive system of each gate.

Japanese Patent Laid-Open No. 5-125713

  However, in the conventional gate control device, since the gate control information is set as a table (array), when the operation request is given once, the target opening degree is set until the operation is completed or unless the operation is forcibly terminated. Could not change. For this reason, for example, when the amount of water flowing into the dam suddenly increases and the water discharge cannot catch up with the initial target opening, the conventional gate control device changes the target opening during the gate opening adjustment operation. However, there was a problem that the response was delayed.

  The present invention has been made in view of the above-described conventional problems, and provides a gate control device capable of continuously performing gate operation based on different gate control information even when the gate is operating. It is aimed.

  In order to solve the above problems, a gate control device according to the present invention is a gate control device for controlling the gate of a dam, and includes gate control information storage means for storing gate control information indicating the control content of each gate; Gate control means for controlling each gate based on the gate control information stored in the gate control information storage means, and the gate control information includes gate designation information and a target opening. Is a linked list connected to other data elements by pointers.

  In the gate control device according to the present invention, the gate control information stored in the gate control information storage means can be rewritten in response to an external operation request for each gate.

  Unlike the table, the linked list does not have a continuous address space. Therefore, it is possible to change the contents of data elements, change the link relationship, and add or delete data elements in units of data elements. Therefore, since the gate control information can be changed by simple update (overwriting), the gate control information can be rewritten without interrupting the gate operation even when each gate is operating. For this reason, even if the gate is in operation, the gate operation can be continuously performed based on different gate control information.

  Further, in the gate control device according to the present invention, the gate control information includes all operations from full gate full closure to full gate operation upper limit opening or full operation from full gate operation upper limit opening to full gate full closure, Each gate is divided into a plurality of operation units, and is created based on a basic operation list in which all operation units are arranged in the operation order.

  According to the gate control device of the present invention, even when each gate is operating, the gate control information can be rewritten without interrupting the gate operation. The gate operation can be performed continuously.

  Embodiments of a gate control device according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing a gate control apparatus according to an embodiment of the present invention.
As shown in the figure, the gate control device 10 of the present embodiment is detected by a control unit 11 that outputs a control command code in response to an operation request from an operation terminal 20 operated by a dam manager, and a water level gauge 21. A drive control unit that adjusts the opening of each gate 23a, 23b,... 23n by applying a drive control signal corresponding to the dam water level and the control command code from the control unit 11 to each gate drive device 22a, 22b,. 12. The drive control unit 12 corresponds to the gate control means in the claims.

  Hereinafter, the control unit 11 and the drive control unit 12 included in the gate control device of the present embodiment will be described in detail.

  First, the control unit 11 includes an operation request reception unit 13 that receives an operation request from the operation terminal 20, and a gate control information generation unit 14 that generates gate control information in response to the operation request given to the operation request reception unit 13. The gate control information storage unit 15 that stores the gate control information generated by the gate control information generation unit 14, and the control command code is generated and driven based on the gate control information stored in the gate control information storage unit 15. A gate control command output unit 16 that outputs to the control unit 12 is provided.

  The gate control information creation unit 14 creates the gate control information 17 corresponding to the operation request based on the base operation list stored in the storage unit 14a corresponding to the gate control information storage unit in the claims. And a storage unit 14a for storing a basic operation list. The base operation list divides all operations when the gates 23a, 23b,... 23n are operated from all gates fully closed to all gate operation upper limit openings into operation units (basic operations) for the gates 23a, 23b,. All operation units are listed in the order of operation with “gate number”, “target opening” and “rank position” as operation units. FIG. 2 shows an example of the basic operation list. The example shown in FIG. 2 is an example in which the number of gates is 2, the upper limit of operation is 200, and the rank is 50, and gate numbers “0” and “1” are assigned to the two gates, respectively, and the operation is performed alternately. Show. As shown in the figure, two types of basis operation lists are prepared: an opening direction basis list applied when the gate is opened and a closing direction basis list applied when the gate is closed.

  Further, as shown in FIG. 3A, the gate control information created by the gate control information creating unit 14 includes a plurality of data elements 30 (30a) each comprising a data part 31 and a pointer part (forward pointer) 33. , 30b,..., 30n) and is stored in the gate control information storage unit 15. The data portion 31 of each data element 30a, 30b,... 30n is configured by a set of a gate number 31a and a target opening 31b corresponding to the gate designation information in the claims. In the pointer section 33, the storage destination address of the next data element 30 is described.

  In the present embodiment, when a change in the target opening, the operation target gate, the operation order, or the like is instructed while the gates 23a, 23B,. The gate control information 17 can be rewritten by changing the contents of the data element, changing the link relationship, and adding or deleting the data element 30 in units of data elements 30. Since the gate control information 17 is a linked list, the pointer unit 33 is rewritten as necessary so that the link relationship of the data elements 30 is consistent. For example, as shown in FIG. 3B, when the fourth data element 30d is deleted, the pointer portion 33 of the third data element 30c is changed from the address of the fourth data element 30d to the address of the fifth data element 30e. To be rewritten.

  The gate control command output unit 16 sequentially reads the data elements 30a, 30b,... 30n from the gate control information storage unit 15, creates a control command code corresponding to each data element, and sequentially outputs it to the drive control unit 12 It is.

  Further, the drive control unit 12 sends a drive control signal based on the control command code sequentially sent from the gate control command output unit 16 and the dam water level detected by the water level gauge 21 to each gate drive device 22a, 22b,. To adjust the opening of each gate 23a, 23b,... 23n.

  As described above, the gate control device according to the present embodiment creates the gate control information 17 composed of the linked list based on the operation request from the operation terminal 20 and each data element constituting the gate control information 17 Based on 30a, 30b,... 30n, control command codes for adjusting the opening degree of each gate 23a, 23b,... 23n are sequentially generated, and each gate is generated according to the sequentially generated control command code and dam water level. Drive devices 22a, 22b,... 22n are driven and controlled. Unlike the table, the linked list does not have a continuous address space. Therefore, it is possible to change the contents of data elements, change the link relationship, and add or delete data elements 30 in units of data elements 30. Therefore, since the change of the gate control information 17 can be realized by simple update (overwriting), the gate control information 17 can be rewritten without interrupting the gate operation even when each of the gates 23a, 23b,. Can do. For this reason, even if the gate is operating, the gate operation can be continuously performed based on the different gate control information 17.

  Therefore, even if the amount of water flowing into the dam suddenly increases and the water discharge cannot catch up with the initial target opening, it is possible to respond quickly by changing the target opening etc. on the operation terminal 20. Can do. Further, even if an incorrect operation request is made, it can be dealt with promptly only by correcting the operation request without stopping the operation of the gate.

  In the present embodiment, the case of a dam having a plurality of gates has been described as an example. However, the present invention can also be applied to a gate control device for a dam having only one gate.
