technical field

The utility model relates to the technical field of on-line monitoring of electric power equipment, in particular to an intelligent substation video monitoring device.

Background technique

A substation is an assembly of some equipment to cut or connect, change or adjust voltage. In the power system, the substation is the assembly point of power transmission and distribution. It is a power facility that transforms voltage, receives and distributes power, controls the flow of power and adjusts voltage. It connects the power grids of all levels of voltage through its transformers. The realization of power transformation and transmission of the entire substation is completed through the cooperation of various equipment. Any failure of any equipment will cause the substation to fail to work normally. Therefore, monitoring of substation equipment is essential. Only when the substation is guaranteed Only when the environment is normal can the power transmission be completed smoothly, providing users with better and more stable power usage.

At present, the most important monitoring method for the substation environment is video monitoring combined with manual inspection. Among them, manual inspection is to regularly inspect all the equipment in the substation one by one by electric workers holding monitoring tools. This method not only consumes a lot of manpower and is inefficient, but also requires the inspector to have enough patience and care. It may lead to errors in detection data, false reporting of equipment status, and even cause great damage to the work of the entire substation. There are increasing requirements in terms of performance, economy, safety, reliability and ease of use; the video surveillance method mainly uses the cameras installed in multiple places in the substation to transmit the pictures captured everywhere to the general control in real time in an all-round way The operating desk in the substation is monitored by the on-duty personnel at any time. Usually, in order to cover most of the substation area, a large number of cameras need to be installed, and so many video image information are transmitted to the general control room at the same time. The control room is also equipped with a TV wall to view each camera scene. Not only is the cost high, but the entire video transmission data volume is also quite large, which brings a lot of burden to the substation video surveillance system.

Therefore, it is urgent to find a more efficient, more reliable, more automatic and intelligent substation equipment monitoring method, and the purpose of substation video monitoring can be achieved by using a small amount of data transmission, which is very important in the substation equipment monitoring work. Necessary, but also has a good application prospect.

The shooting screen is transmitted to the general control room, which reduces the manual inspection rate on the one hand and saves a lot of manpower. On the other hand, it can realize self-identification of abnormal conditions in the environment, greatly reducing the amount of video data transmission, and making resource allocation and utilization more efficient. Reasonable, while greatly improving the intelligence and automation level of the video surveillance device.

In order to solve the above problems, the utility model adopts the following technical solutions:

A video monitoring device for a smart substation, comprising: a camera unit, a storage unit connected to the camera unit, a central control unit, a wireless communication unit, and a power supply unit; wherein an infrared hotspot sensing unit is set at the camera unit, and the infrared The hotspot sensing unit is connected to the central control unit; the storage unit is connected to the wireless communication unit through the central control unit; the power supply unit is connected to the camera unit, storage unit, infrared hotspot sensing unit, and central control unit respectively. Unit and wireless communication unit connection.

Preferably, the storage unit is a hard disk memory.

Preferably, the central control unit is a single-chip microcomputer or PLC.

Preferably, the wireless communication unit is a GSM, or CDMA, or satellite communication module, and a unique binding transmission is established with the general control room.

Owing to adopting above-mentioned technical scheme, the utility model has following advantages:

1. An infrared hotspot sensor is added to the camera, which can effectively perceive infrared hotspots, and monitor the equipment based on the changes of infrared hotspots. It does not require the staff to manually detect the substation equipment one by one on site, saving a lot of workload and making it more automated. ;

2. Real-time monitoring and analysis of infrared hotspots, intelligently detect whether there are abnormal hidden dangers in the monitored area;

3. Using wireless communication technology, the video image information captured by the camera is wirelessly transmitted to the main control room host, saving the use and maintenance of long-distance cables;

4. When the infrared hotspot sensor has an abnormal prompt, the real-time shooting picture corresponding to the area will be transmitted to the main control room host, and the shooting pictures of other normal areas will only be stored in the corresponding storage unit, and do not need to be transmitted to the main control room , This greatly reduces the amount of video data transmission, makes the allocation and utilization of resources more reasonable, and makes video surveillance more intelligent and automated.
