The core control unit 1 is an XWT series communication management machine, and the core control unit 1 includes an embedded ARM9 industrial-grade main card, Samsung S3C2440ACPU, Ethernet port, serial interface, USB interface, and CDT, 101, 104, DNP, 1801. MODBUS protocol.

The core control unit 1 is burnt with video control self-programming software.

The horizontal physical isolation device 2 is used to configure various information of the isolated equipment, and to control the establishment and application of various access control rules of the isolated equipment (see Figures 1-2).

The substation scada monitoring information and video linkage control system can control the scada monitoring information linkage of not less than 200 substation cameras at the master station, without affecting the operating structure and existing functions of the existing integrated self-system. Monitor system security.

On the one hand, the core control unit 1 receives and analyzes the remote control displacement information of each substation sent by the real-time switch 3 of the data network, and issues instructions to the hard disk video recorder 7; Send instructions. The hard disk video recorder 7 controls the corresponding camera after receiving the instruction issued by the core control unit 1 .

The original integrated automation system and video system at the substation end are two independent systems. Through the joint control of the substation scada monitoring information and video linkage control system at the end of the station, the integrated automation system and video system at the end of the substation can be effectively integrated. , to maximize the role of the video system, and fully improve the application value of the video system. Realize one signal (an uplink or downlink message) to start the rotation of multiple cameras to achieve the purpose of all-round video surveillance; multiple signals (any combination of remote signaling and remote control) respectively start the rotation of the same camera, so that the same camera can be rotated in different Monitor different devices at all times to achieve the purpose of making full use of the camera.

The working process of the substation scada monitoring information and video linkage control system is as follows:

Appropriately supplement and adjust the number and position of cameras according to the original video system configuration on site.

Install the core control unit 1 on the basis of the original video system on site, and improve the protocol interface with the hard disk video recorder 7 of the station-side video system and the dispatching data network of the station-side integrated automation system.

The camera power supply and the working power supply of the core control unit 1 are 220V alternating current, which can be provided by the substation.

In order to ensure network security, a horizontal physical isolation device 2 is added. Between the real-time switch 3 of the dispatching data network and the core control unit 1, the substation is safely isolated through the horizontal physical isolation device 2 to meet the requirements of secondary protection.

Through the monitoring of network messages, the protection action signal, alarm information, remote control command and other information in the scada monitoring information are separated, combined with the control of the hard disk video recorder 7, the linkage between the scada monitoring information and the video system is realized.

By programming the video software of the core control unit 1, the core control unit 1 directly controls the hard disk video recorder 7 through the video network at the main station end, thereby realizing the linkage control of the camera of the station end video system 8.

All scada monitoring information can be monitored at the mirror port of the data network real-time switch 3, requiring the receiving capacity of the intelligent communication network card to be no less than 100M bytes/second.

Remote operation monitoring: according to the downlink 'preset' command operated by the supervisor, the camera near the operation unit at the substation station will automatically rotate and aim at the corresponding electrical equipment 'opening/closing' instructions, and the supervisor can monitor through the video surveillance screen The whole process of remote control operation (before, during and after operation);

Circuit breaker trip monitoring: When the electrical equipment at the substation end trips abnormally, the integrated automation system will send uplink remote signaling messages such as "protection exit" and "circuit breaker division". The core control unit 1 intercepts and analyzes the IEC104 network message of the scheduling communication between the communication host 4 of the integrated automation system and the dispatching system 5 of the master station through the mirror port configured by the data network real-time switch 3, and then starts the control process of the core control unit 1, Start the hard disk video recorder 7 to mobilize the camera pan/tilt of the station-side video system 8. At this time, the camera near the tripping circuit breaker automatically rotates and aligns with the corresponding electrical equipment "open/close" indicator. On the basis of judging the operating status of the equipment based on the change of the message, the independent visual judgment basis is added to make the control operation more accurate and reliable.

Although the original monitoring system and station-side integrated automation system can meet the needs of substation remote operation monitoring and remote control operations, they only judge and control through the "indirect monitoring" method. After using the substation scada monitoring information and video linkage control system, monitoring personnel You can visually observe the position and status of electrical equipment through the video screen to see if the operation is in place. It supplements and improves the operation specified in the "State Grid Corporation of Electricity Safety Work Regulations (Transformation Part)", which fully meets the "State Grid Corporation of Electricity Safety Work Regulations (Transformation Part)" 5.3.6.6 of the Electrical Part) (2013 Edition) requires: "The position inspection of electrical equipment after operation should be based on the actual position of each phase of the equipment. When the actual position cannot be seen, indirect methods, such as equipment mechanical Position indication, electrical indication, electrified display device, instrument, and various telemetry, remote signaling and other signal changes. When judging, there should be at least two indications of different principles or non-homologous corresponding changes, and all of these determinations The instructions have changed correspondingly at the same time, and then it can be confirmed that the equipment has been operated in place. The above inspection items should be filled in the operation ticket as inspection items. If any other signals are found to be abnormal during the inspection, the operation should be stopped and the cause should be found out. If remote control operation is performed, the above-mentioned indirect method or other reliable methods can be used to determine the location of the equipment", which greatly improves the frequency and value of the 8 cameras of the station-side video system. The actual use of the substation scada monitoring information and video linkage control system in the county-level power grid substations of Hubei Province shows that the work is stable and reliable, the information is accurate, the work is stable and reliable, and the monitoring operation efficiency is improved.

The above is only the specific implementation of the utility model, and the above examples do not limit the essential content of the present utility model. Those of ordinary skill in the art can modify or deform the above-mentioned specific implementation after reading this specification. Without departing from the spirit and scope of the present utility model.
