Fire sign detection device and method

Abstract

The invention provides a fire sign detection device and method. The device comprises a shell, a shading hood, a suction fan, a master control unit and a detection assembly. The suction fan, the master control unit and the detection assembly are arranged in the shell, the suction fan is located at a suction inlet of an upper cover, the input end of the suction fan is connected with a fan control output end of the master control unit, a detection chamber of a maze structure is disposed in the inner space of the shell, the detection assembly arranged in the detection chamber comprises a light source module and a scatter receiving detection amplifier circuit module, the light source module comprises two emitting tubes and two collimating lenses, and the input ends of the two emitting tubes are connected with the light source control output end of the master control unit. Multi-information synthesis detection is combined with a sunk detection light path structure of special design so that sensitive detection of micro sign information in the pyrolysis process in a fire breeding stage can be achieved, meanwhile, categories of pyrolysis particles with different attributes are judged, early sign detection is achieved, and meanwhile reliability of a detector is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of fire sign detection, and in particular relates to a fire sign detection device and method. Background technique [0002] Fires caused by electrical reasons account for a quarter of the fire accidents over the years. Therefore, electrical fire prevention is the top priority in fire safety, especially all kinds of power distribution cabinets, switch cabinets, control cabinets, etc., which carry electrical energy. For important functions such as transmission and distribution or signal decision-making, early detection of fires for such cabinet-type electronic control equipment has always been a practical need in safety production, and it is of great significance to prevent fires, protect people's lives and property, and avoid huge economic losses. [0003] In all kinds of cabinet-type electronic control equipment, although there are overcurrent or residual current monitoring and protection devices to prevent ...

Problems solved by technology

However, due to the weak sign information, it is easy to be submerged with the disturbances in the environment. High-sensitivity detection may lead to an increase in the false alarm probability of the sign detector in some cases. The sign detector is a feature of high-sensitivity signs The specific implementation of attribute recognition and detection technology, the selection of key components, the design of recognition algorithms, the design and improvement of circuit systems, the optimization of optical paths and the cooperation of various structural components all require repeated testing, analysis and adjustment during the development process.
