Abstract

PURPOSE:To attain an integrated and centralized remote supervisory and controlling system including a non-remote control device, by providing an information area for a non-remote control device at a memory part for supervisory and controlling performed at a control center. CONSTITUTION:A temporary position data part 20b having the same form as a real position data part 20a is allocated to a processing information memory part 20 for a non-remote control device. An operation equal to the input of control information on the remote control device is carried out by means of an input means of a monitor board 26. Thus the information on the device and others are written for each position by the processing of a supervisory/ control part 22. While the information on the part 20b is displayed on a CRT24 and the board 26 via the part 22. It is just required to rewrite the position type in case a non-remote control device is converted into a remote control device.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a remote monitoring and control system applied to power equipment, for example.

Kunikira's technology〉 Remote monitoring and control systems have been applied to electric power equipment for a long time, and systems are gradually becoming more centralized. The basics of a remote monitoring and control system is that the status information of each field device at the controlled station is transmitted to the control center by a remote monitoring and control device (hereinafter referred to as TC device), and the status of the field devices is displayed and monitored at the control center. At the same time, the control information generated at the control station #2 is transmitted to the controlled station by the TC device, and all the field devices are controlled as specified.

<Problems to be solved by the invention> The great significance of remote monitoring and control is labor saving and integration (centralization). By remotely monitoring and controlling on-site equipment, the number of operation and maintenance personnel can be reduced, which is labor-saving. Integration and centralization are, for example, a means of monitoring and controlling the relationship between scattered devices or power equipment in the overall movement of the entire process, by centrally controlling several locations from the center of the process. It is intended to remotely monitor equipment in one facility, and is mainly aimed at high quality and efficient operation, such as controlling equipment in other facilities using information from one facility's equipment.

In the latter case, the result is still the same labor-saving as the former, but while the former's main purpose is rationalization by reducing personnel, the latter's goal is to improve the quality of the overall plant finish. Due to the demands of
The difference is that the main focus is to comprehensively understand the entire plant. Therefore, in the latter case, it is unavoidable even if labor savings cannot be achieved. In other words, in some cases, the controlled facility may not be completely unmanned.

Particularly in the transitional period in which the centralization of remote monitoring and installation systems is being promoted, some field equipment will inevitably be excluded from the scope of remote monitoring due to constraints on the transmission capacity of TC devices. Devices that are not covered by these devices (referred to as non-remote control devices)
In the future, many will be made remote controlled. In the case of power transmission/distribution service leaks, the secondary disconnect switch of the main transformer is often routed to non-remote control equipment.

Regarding conventional remote monitoring and control systems, the above-mentioned integration and centralization of non-remotely controlled equipment have not been taken into account, making it difficult to comprehensively understand the entire plant. In addition, there were other problems such as the troublesome changes to be made when converting a non-remote control device to a remote control device.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to integrate and centralize the system, including non-remote control equipment, and to achieve high-quality and highly efficient operation of the entire plant. It is an object of the present invention to provide a nine-distance monitoring and control system that can be realized and easily changed when converting a non-remote control device to a remote control device.

Therefore, in the present invention, non-remote control equipment (non-remote control equipment) is stored in the storage unit for supervisory control in a control center in the same format as the information area of remote control equipment (monitoring and control target equipment). Provide an information area for the target device, make it possible to identify from the stored information whether it is a remote control device or a non-remote control device, and display the stored information of both devices equally; A means of changing memory information was established.

In the system of the present invention, non-remote control equipment is treated in the same manner as remote control equipment in the control center, and the status of the non-remote control equipment is displayed on the display together with the remote control equipment. Is displayed. In addition, the status information and display of non-distant control devices can be freely changed by operating the control panel.

<! i! Fabric Example> FIG. 1 shows a system configuration according to a -*m example of the present invention. A large number of field devices 10 are scattered at the controlled station, some of which are remotely controlled devices and others are non-remotely controlled devices. The remotely controlled field equipment 0 is connected to the TC coupling section 16 of the control center 14 via a large number of TCC devices 12 via a data transmission path.

The control center 14 is composed mainly of computers), and includes an online input/output information storage section 18, a processing information storage section, a monitoring control section n, a CRT wing for visual control, a general monitoring panel, etc. have

The state information of the remote control device is transmitted to the TC coupling section 16 via the TC device 12t, where the information format is converted and stored in the TC online input data section 18a of the storage section 18. The format of this TC on-twin input data section 18a is shown in FIG. As shown in Figure 2, each TC device 1
The word received from 2 corresponds to the word in the storage unit 18,
Each word includes a remote control position data section (for 10 positions) representing the device status and a flag section.

The monitoring control unit n compares the TC online input in the storage unit 18 with the previous manual data, detects data with a state change, and writes it into the corresponding area of the processing information storage unit. The storage unit includes both an actual position data section 20a, which is an information area for remote control equipment, and a temporary position data section 20b, which is an information area for non-remote control equipment. Figure 3 shows the format of this memory section. The data structures of the actual position data section 20a and the temporary position data section 20b are the same and consist of position type (7), equipment information (a), and other information (b). The position type (to) includes an identifier indicating whether it is a remote control device or a non-remote control device.

The difference between data 520jL and 20b is the position type (7
) information.

In the case of remotely controlled equipment, the equipment information (ON/OFF status information) transmitted by the TC device eL2 is processed by the monitoring control unit as described above, and the actual position data unit 20a is processed.
The person is seen in the relevant area.

The information in the actual position data section 20a is displayed on the CRT 24 and the monitoring board through processing by the monitoring control section n.

Further, remote control equipment is controlled by the input means of the CRT 24 or the monitoring panel. First, the device O to be controlled
Specify the position, then control details (ON-OFF'
). This control information is read by the supervisory control section n and inserted into the control output section 18bK of the storage section 18. The control information of the control output section 18 fi is transmitted from the TC coupling section 18 to the corresponding TC device 12 according to a predetermined transmission procedure. According to the control information, the relevant on-site equipment IO is controlled. Zero or more are the flow and processing of information related to remotely controlled equipment. For non-remote control devices, there is no information exchange path between the TC device 12 and the TC coupling unit 16, and they are connected to the control center 14 by other means such as using telephones and human hands.

For non-remote control devices, please contact TC Online Data Department 18
a, control output parts ta and b are not assigned, but
As described above, a temporary position data section 20b having the same structure as the actual position data section 20a is assigned to the processing information storage section. Device information (fAf) and other information (fAf) for each position in the temporary bonding data section 20b
I can relate to fi. This control is performed by the process of the monitoring control unit n when an operation equivalent to inputting control information of the remote control device is performed on the monitoring panel manually. Also, the information in the temporary position data section 20b is controlled by the monitoring control cape section 4 in the same way as the information in the actual position data section 20a.
Displayed on RT 24 and monitoring board.

That is, the supervisory control unit ρ distinguishes the information in the processing information storage I based on the position type (7). If the input means receives a control input for the device, if the specified position is a remotely controlled device, the above-mentioned control output O online processing will be performed, and if the specified position is a non-remotely controlled device, the corresponding data in the storage bank will be processed. Performs only the process of updating the . Actual position data section 20
Since both a and the temporary position data section 20b have the same format, the handling by the monitoring control section η may be the same. In addition, when a non-remote control device is converted to a remote control device, it can be easily handled by simply changing the position type (7). <Effects of the Invention> As explained above in detail in 5, the remote monitoring system according to the present invention With the installation system, it is possible to centrally understand the entire process, including non-remotely controlled equipment, resulting in high quality integration and
A centralized system can be easily configured. Also,
Changing the system when converting non-remote control equipment to remote control equipment will also be very difficult.
