Thermal disaster detecting device used in confined space

Abstract

The invention relates to a thermal disaster detecting device used in a confined space. The thermal disaster detecting device is characterized by comprising a mounting substrate (1), a thermal disasterdetecting sensor (2), a bus structure (3) and a controller (4). Through forming a plurality of the thermal disaster detecting sensors into an array, the problem that a single thermal disaster detecting sensor has limited sensing range in a confined space, the plurality of sensors are connected by means of the bus structure, the specific position where a thermal disaster occurs can be positioned precisely by means of the sensors while sending out a thermal disaster alarm; and since the plurality of the thermal disaster detecting sensors are adopted to form the array, and the failure of a single sensor does not affect the normal monitoring operation of other sensors, thereby avoiding the situation that the entire detection process fails due to the failure of the single sensor; meanwhile, the sensors are detected in an array, thus the detection sensibility is higher than that of a single sample.

Description

technical field [0001] The invention belongs to the technical field of thermal disaster detection, and in particular relates to a thermal disaster detection device used in a confined space. Background technique [0002] Thermal disasters are a common disaster phenomenon that occurs frequently in the fields of electric power and chemical industry. The existing countermeasures are generally to install infrared thermal imaging devices near the location of the equipment to be monitored for thermal disaster detection, or to use smoke, temperature, infrared , Ultraviolet method to detect fires in the late stage of thermal disasters. However, none of the existing detection and detection products can be installed in a small space, such as a battery cabinet with a compact space, and a large area of ​​narrow gaps with only a few centimeters between the battery and the casing. Conventional infrared thermal imaging products, smoke, temperature and Infrared and ultraviolet products cann...

Problems solved by technology

However, none of the existing detection and detection products can be installed in a small space, such as a compact battery cabinet, a large area of ​​narrow gaps with only a few centimeters between the battery and the casing, conventional infrared thermal imaging products, smoke, temperature and Infrared and ultraviolet products cannot be installed normally at all, so it is impossible to realize comprehensive and effective thermal disaster monitoring and early warning for monitoring equipment
