Fig. 3 is a schematic structural diagram of an interactive control system of a power system according to an embodiment of the present invention. Referring to Fig. Gates and circuit breakers, air conditioning equipment, electric heating equipment, lighting equipment and water pumps, the collector collects real-time information from the above subsystems and transmits them to their respective control units, such as perimeter alarm control unit, fire alarm control unit, equipment status control unit, Air conditioning remote control unit, heating remote control unit, lighting remote control unit, centralized drainage control unit. The above-mentioned control unit sends the received real-time information of each subsystem to the protocol control host of the internal network, and finally transmits it to the system command center or the local client. The system command center or the local client controls the abnormal subsystem through the controller.

Fig. 4 is a schematic diagram of the connection of multiple subsystems of the interactive control system of the power system according to an embodiment of the present invention. Referring to Fig. 4 for details, the above-mentioned subsystems are preferably: fire alarm system, drainage monitoring system, perimeter alarm system, and remote lighting control system, heating remote control system, air conditioning remote control system, secondary equipment status linkage system.

Through the above embodiments, it can be seen that the entire power system is composed of eight preferred modules, involving video linkage, perimeter linkage, fire linkage, equipment status linkage, air conditioning remote control, heating remote control, lighting remote control, centralized drainage monitoring and so on. The system structure is as follows: Video access control unit: responsible for the access and control of the video system, and the mutual linkage with other systems. Perimeter alarm control unit: responsible for the access of the perimeter alarm system and the linkage with the video system. Fire alarm control unit: responsible for the access of the fire alarm system and the linkage with the video system. Equipment status control unit: responsible for the access of the equipment status alarm system and the linkage with the video system. Air conditioner remote control unit: responsible for the remote start and control of the air conditioner system. Heating remote control unit: responsible for remote monitoring and status collection of the heating system. Lighting remote control unit: responsible for remote control and status acquisition of the lighting system. Centralized drainage monitoring unit: responsible for remote monitoring and status collection of the centralized drainage system.

Specifically, the video monitoring system is an unattended key system in the substation. The video monitoring system is placed in the place where the auxiliary equipment operates. When the auxiliary equipment has abnormal conditions, it is reflected in the video information of the client, and the equipment can be operated through the software platform. And management, such as shutdown and regulation, if the situation is serious, you can immediately notify the relevant personnel to go to the scene for emergency repair or rescue. The alarm signals of all equipment are displayed in the video system. After receiving the alarm signal, the control center needs to call out the video image of the alarm scene or go to the alarm scene to check whether it is a false alarm. This period of time may have been missed. The number of false alarms will cause paralysis of monitoring personnel. The linkage between video and alarm, you can see the video image of the alarm scene, monitor the sound of the scene, and control the lighting and other equipment at the alarm scene at the same time as the alarm.

In the same way, the state linkage of high-voltage operating equipment, the position switching of high-voltage operating equipment such as circuit breakers and isolating switches, is the key equipment operation, which is very important for the safety of substations. When the position of high-voltage operating equipment is switched, the video system can be triggered according to the device and the position, turn to the switching area in time, so that the monitoring personnel can quickly grasp the on-site situation and judge whether the on-site situation meets the requirements, and the video linkage of the position change of the isolating switch can record the switching status of the equipment in time, which is convenient for the operation and maintenance personnel to view and handle. The close-up tracking and monitoring method of video moving targets based on the linkage structure uses a panoramic surveillance camera to identify the knife switch change and key operations in the monitoring area, and after determining whether the knife switch change and key operations meet the requirements, the information is transmitted to the PTZ The close-up tracking camera that controls the steering, the close-up tracking camera close-ups the locked target, zooms in and tracks, and displays the close-up picture of the switch switch, so as to obtain more information about the target. It can not only monitor the panorama, but also automatically judge suspicious targets, and realize the function of close-up tracking.

Similarly, the perimeter alarm is an important alarm device in the substation. When the device alarms, the video system can turn to the alarm area in time according to the alarm device and its location. The video tracking linkage of the perimeter security alarm, when the perimeter alarm alarm (normally open alarm signal), the camera image is automatically switched to the monitor, the on-site sound is monitored, and the alarm status of the equipment is recorded in time, which is convenient for operation and maintenance personnel to view and monitor. deal with. Perimeter alarms require video linkage. After receiving the alarm signal, the control center needs to call out the video image of the alarm scene or go to the alarm scene to check whether it is a false alarm. Too many alarm times will paralyze the monitoring personnel. The linkage between video and alarm, you can see the video image of the alarm scene, listen to the sound of the scene, and control the lights and other equipment on the alarm scene at the same time as the alarm.

In the same way, the air conditioning system can only be controlled locally in the traditional system, and it is very difficult to manage and maintain unattended substation equipment. In this system, the equipment can be managed and controlled locally, and remotely managed and controlled through the internal network of the substation. This system can observe the current operating status of the air-conditioning system in the monitoring center, and understand the specific conditions of the air-conditioning system in real time. Once the equipment fails, it can know the status quo in time, and can promptly notify the maintenance personnel to carry out maintenance, and record the results of the judgment status down. And it can be remotely controlled to start or stop manually or automatically according to the indoor air conditioner.

Similarly, the heating system can only be controlled locally in the traditional system, and it is very difficult to manage and maintain unattended substation equipment. In this system, the environmental parameter acquisition system can be used to remotely monitor the operating status of the electric heater. This system can observe the current operating status of the heating system in the monitoring center, and understand the specific situation of the heating system in real time. Once the equipment fails, it can understand the status quo in time, and can promptly notify the maintenance personnel to carry out maintenance, and record the results of the judgment status down. And can carry out remote monitoring according to the indoor heating system.

Similarly, the fire fighting system is very important to the safety of the substation. When the fire alarm equipment alarms, the video system can turn to the alarm area in time according to the alarm equipment and location, so that the monitoring personnel can find the fire at the first time and notify the firefighters in time. Control the fire scene, and you can easily check the conditions of the equipment that caused the fire and the equipment involved in the fire, and the fire alarm video linkage can record the alarm status of the equipment in time, which is convenient for operation and maintenance personnel to view and deal with. Fire alarm requires video linkage. After receiving the alarm signal, the control center needs to call out the video image of the alarm scene or go to the alarm scene to check whether it is a false alarm. During this period, the real alarm may have been missed, and the false alarm Too many times will cause the paralysis of the monitoring personnel. The linkage between video and alarm, you can see the video image of the alarm scene, listen to the sound of the scene, and control the lights and other equipment on the alarm scene at the same time as the alarm.

In the same way, the lighting system in the station can only be controlled locally in the traditional system, which is very difficult for the management and maintenance of unattended substation equipment. In this system, the equipment can be managed and controlled locally, and remotely managed and controlled through the internal network of the substation, and the status results can be recorded. The system can transmit the working parameters (including voltage, current, active power, power factor, power consumption, lighting rate, frequency, etc.) of each substation on site to the computer in the central control room. low limit, high voltage limit, low current limit, high current limit, lighting during the day, low lighting rate) timely anti-dial number alarm, especially the lighting rate of each substation, anti-dial number alarm for daytime lighting, high current limit anti-dial alarm Dial-up alarm, so that you can know the working situation of the substation in time without sending people to inspect, and arrange manual maintenance in time, which not only ensures the lighting rate and equipment safety, but also improves the management to a higher level.

In the same way, the state of the centralized drainage system is very important for the safe and stable operation of the substation, but in the traditional system, it can only be controlled locally, and remote monitoring cannot be realized. The drainage remote centralized monitoring system automatically monitors the ambient temperature, humidity and fire prevention, anti-theft, waterproof, water pump working status, water level, flow and other conditions of the computer room, and combined with remote control, it can completely realize unattended. It can highly intelligently analyze and judge the alarm status of various parameters, and promptly report the name, location, and nature of the fault to the monitoring center, such as water pump failure, fire alarm, equipment power failure, and excessive pipe network pressure. The information is recorded and processed through the monitoring center, and office automation is also realized. Remote image monitoring can also be realized for important computer rooms. The system can not only monitor the centralized drainage system in real time, record the specific conditions of the centralized drainage system, but also remotely monitor the centralized drainage system and report the status signals step by step through the existing multi-level network of the substation, which is convenient for unified management and maintenance. The management of personnel has brought great convenience.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
