Description

Substation infrared temperature measurement alarm and data processing system

technical field

The utility model relates to a power grid safety device, in particular to an infrared temperature measurement alarm and data processing system for a substation.

Background technique

A substation is an important power equipment that can convert voltage and current and realize the acceptance and distribution of electrical energy. Substations usually have complex lines, harsh working environment, high electromagnetic interference, high temperature, high voltage and other characteristics. Once the local temperature is too high, it is easy to catch fire and burn. Therefore, the fire warning/monitoring system of substations is particularly important.

At present, there are various types of alarm systems for power grids on the market. CN209841198U discloses a high-voltage power distribution cabinet with a temperature measurement function. The infrared heat distribution inside the power distribution cabinet is monitored by infrared thermal imaging technology, and an alarm is issued once abnormal. CN208313439U discloses a temperature detection device, which also monitors changes in infrared characteristics of important power facilities through an infrared thermal imaging device, and wirelessly transmits the monitoring results to remote managers through a wireless communication device. However, these monitoring and alarm systems have a very simple structure and a single data source, and basically rely entirely on infrared cameras. Once they fail or their status changes due to various reasons (such as wind blowing, maintenance collision, etc.), the monitoring results may be caused. There is an abnormality and a false alarm occurs, which often happens in reality. In addition, such existing monitoring and alarm systems cannot efficiently analyze and process the collected data. Once the amount of data is large or there are many substations that need to be monitored, it will bring great trouble to management. Finally, the existing monitoring and alarm systems of this type are often only one-way communication (substation to management terminal), and detailed on-site images cannot be obtained in time for management personnel to analyze and make decisions after an abnormality occurs in the equipment.

The utility model uses the infrared camera to collect the temperature data of the substation, and additionally adds a microphone array and a motion detection module in order to ensure the multiplicity and reliability of the data sources. This is because the abnormal temperature of the substation is often accompanied by abnormal noises (such as burning, explosion), and these sound information can assist in verifying the early warning results of the infrared camera. In addition, the microphone array can also monitor the abnormal invasion of the substation caused by the activities of external animals or people, so as to prevent damage to the substation. The motion detection module is to ensure the consistency and reliability of the position status of the infrared camera and the microphone, so as to ensure the authenticity of the collected data and prevent false warning messages. The main server and its software can receive the collected infrared images and process them, and display the processing results intuitively and vividly, which greatly reduces the difficulty of management. Compared with the existing similar equipment, the system provided by the utility model has the advantages of simple structure, many sources of warning data information, and high reliability.

Detailed ways

In order to make those of ordinary skill in the art fully understand the technical solutions and beneficial effects of the present invention, further description will be given below with reference to specific embodiments.

As shown in Figure 1, a substation infrared temperature measurement alarm and data processing system mainly includes in-station equipment installed around the substation, a remote main server and a mobile terminal. The equipment in the station includes a camera array, a microphone array, a motion detection module, a control module and a communication module that are electrically connected to each other. The camera array includes several 100W pixel infrared cameras based on the OV7725 camera module and 1080P high-definition night vision cameras based on the USB camera module arranged in the key monitoring parts of the substation, and motion detection is fixed on the two cameras and the microphone array. module. Infrared cameras and high-definition night vision cameras are used to collect infrared temperature information and real-time image information of the substation, respectively, the microphone array is used to detect abnormal noise information in the surrounding area of the substation, and the motion detection module is used to monitor the position and motion status of the camera array and microphone array. change information.
