Fire detection, prevention and control system of electronic control cabinet and control method thereof

Abstract

The invention relates to a fire detection, prevention and control system of an electronic control cabinet. The fire detection, prevention and control system comprises a data acquisition device, a fire extinguishing device and a main control device which are arranged in an electronic control cabinet body, wherein the data acquisition device is used for acquiring detection data of each detection node in the electronic control cabinet in real time, and transmitting the detection data to the main control device; the fire extinguishing device is used for accepting a control signal sent by the main control device, and carrying out fire control and processing on an area with a fire early warning; a fire extinguishing control module is used for sending a control signal to the fire extinguishing device according to the instruction of a CPU (central processing unit) core module. The invention further discloses a control method based on the system. The control method comprises the following steps: transmitting the CO and smoke concentration acquired in real time to the CPU core module; processing by a pre-detection data filter model to obtain a characteristic extraction value; if fire early warning standards are met, sending an early warning or starting the fire extinguishing device. The fire detection, prevention and control system and the control method disclosed by the invention are capable of performing real-time detection on a small space such as the electronic control cabinet, eliminating fire in the bud, and reducing the false alarm rate of fire early warning.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to an electric control cabinet fire detection prevention control system and a control method thereof. Background technique [0002] With the rapid development of modern technology, electric control cabinets have become an important part of the automation system, such as high and low voltage switch cabinets, PT cabinets, communication cabinets, control cabinets, electric vehicle charging cabinets, wind power control cabins, etc., such small There are more and more applications of space electrical function boxes. The functions are becoming more and more complete, and the degree of system correlation is getting higher and higher. A small fire will cause very serious consequences and major economic losses. For example, in recent years, building fires caused by electrical short circuits etc. have occurred frequently. According to statistics, in numerous fire accidents, the fire...

Problems solved by technology

These traditional treatment methods have the following defects: First, because most of the operating equipment in the computer room are power distribution cabinets, network cabinets, and cable tunnels or bridges, etc., most of the sources of fire exist in these relatively closed local spaces. The measures cannot monitor and automatically extinguish the fire in a confined space in real time, so the source of the fire cannot be controlled.

When a fire occurs in the cabinet, the video surveillance in the computer room cannot be detected in time, and the fire protection system can only be activated when the fire expands to a certain extent. At this time, the equipment in the computer room has caused serious losses; The agent will pollute other equipment in the computer room, and the follow-up cleaning is very cumbersome; third, because the cabinet is a closed or semi-closed space, it is not easy to implement fire monitoring in it by manual observation, and it depends entirely on the judgment of the device, so it is very important to reduce the false alarm rate to the greatest extent. Important; in addition, the method of hanging fire-fighting containers outside the cabinet destroys the cabinet structure, and most cabinets cannot be installed due to their location
