Description

Technical Field

[0001] The utility model relates to the technical field of combustible gas leakage alarm systems, in particular to a gas leakage monitoring and alarm device. Background Art

[0002] A gas leak alarm is a system used to monitor the concentration of specific gases in the environment and sound an alarm when the dangerous threshold is reached. In an industrial production environment, there may be leakage of harmful gases, such as carbon monoxide and hydrogen sulfide. The gas leak alarm system can detect the leakage of these dangerous gases in time and remind staff to take corresponding safety measures, such as evacuating personnel, shutting off the gas source, etc., to avoid casualties and property losses; in the home, a gas leak alarm device can also be installed to monitor the leakage of natural gas, liquefied gas, etc., to ensure the safety of family members; a gas leak alarm system is usually composed of a gas sensor, a controller and an alarm device.

[0003] The gas sensor is responsible for detecting the gas concentration. When the concentration exceeds the set threshold, the signal is transmitted to the controller, which then triggers the alarm device to send out an audible and visual alarm signal. Some advanced gas leak alarm systems also have data recording and remote communication functions, which can transmit the detected data in real time to the monitoring center or the mobile phones of relevant personnel, so as to timely grasp the gas leakage situation and take countermeasures. The gas leak alarm system is an important equipment to protect people's lives and property safety, and is widely used in various places where there may be risks of gas leakage.
