In the field of fire protection and security equipment technology, the front-end hardware equipment of traditional smoke detection systems is of single type and low intelligence. In the case of sudden, variable, smoke toxicity and transient fire conditions, it is impossible to provide timely and effective on-site status support for the fire control center's action decision making and on-site command, which seriously endangers the safety of life and property of rescuers and the people. As a front-line monitoring equipment, the fire alarm system puts forward higher requirements for the highly intelligent integration and linkage coordination of smoke detectors. The front end of the detector integrates various information acquisition modules such as microwave radar, smoke, and temperature. The core is designed based on the multi-source heterogeneous system architecture system. It can timely judge the defects of personnel and flames, reduce the occurrence of misjudgments, and use low-power narrowband communication technology to solve the problem which the traditional 4G/WiFi communication method has the defects of low transmission efficiency and short working life.
