An alarm protection structure for the main board of a gas detector

Abstract

A alarm protection structure of the motherboard of the gas detection instrument, including: including power supply unit, display unit, dust alarm unit, temperature and humidity alarm unit, sound and light alarm control unit.The alarm unit and the sound light alarm control unit are connected to the motherboard of the gas detector instrument, which includes a dust filtering alarm device with a temperature and humidity alarm unit with temperature sensors and humidity sensors.The purpose of the present invention is to provide a alarm protection structure of a gas detection instrument. It has the role of alarm warning when the motherboard of the gas detection instrument in a harsh environment at the same time meets a certain condition, and has the advantages of facilitating the accumulation of dust stacking.

Description

technical field [0001] The invention belongs to an alarm device structure, in particular to an alarm protection structure for a main board of a gas detector. Background technique [0002] In the industrial production environment, the gas detector is used to detect and display the concentration of a specific type of gas, which is an indispensable standard equipment in the industrial production process. [0003] Aiming at a large-scale gas detector used in the space environment of petroleum, chemical industry, pharmaceutical, smelting and other fields, the detector has been in an environment with poor air quality, and the poor air quality includes relatively high content of volatile gases. Many, large gas dust content and other conditions. [0004] The main body of the gas detector is the main body of the gas detector, which carries the tasks of information processing, command transmission and power transmission in the gas detector equipment. During the use of the main board,...

Problems solved by technology

[0004] The main body of the gas detector is the main body of the gas detector, which carries the tasks of information processing, command transmission and power transmission in the gas detector equipment. During the use of the main board, the traditional gas detector will not protect the state of the main board. And early warning, this will cause the motherboard room of the gas detector in extreme air quality to work in an environment with poor air quality, and the motherboard running in this working state for a long time will be damaged due to dust, temperature, humidity, etc. The impact will seriously interfere with the normal operation of the motherboard and reduce the service life. In serious cases, it may cause emergencies that endanger the staff
