[0002] Gas detection alarm controller is a kind of on-site monitoring alarm equipment widely used in industrial enterprises. It is usually used to detect gas leakage in dangerous areas such as production or warehouses. For example, it is used in petrochemical, oil depot, liquefied gas station, gas station, gas station, paint room, sewage treatment and other places that need fire prevention and toxic gas leakage for safety detection and alarm.

[0003] Most of the existing gas detectors are installed in fixed positions. Due to the different heights, the gas concentration will also be different. The fixed installed gas concentration alarm device cannot be moved for detection, so it is impossible to detect the concentration at different heights, which reduces the accuracy of the detection.

This utility model can meet the installation requirements of different scenarios by setting up two data transmission methods: wired and wireless. In addition, the power module used includes a switching power supply and a battery, thereby improving the reliability of the operation of the gas detection alarm control device.

[0005] However, when in use, the device can only detect gas at a specific location. Due to the different altitudes, the gas concentration will also be different, and the fixed gas concentration alarm device cannot be moved for detection, so it is impossible to detect the concentration at different heights, reducing the accuracy of the detection. Utility Model Content
