Design of Smoke-temperature Composite Detector Based on HWD32

Aiming at the problem that traditional fire detectors can only detect single hazard feature, a domestic smoke-temperature composite detector based on HWD32 is designed. The functional requirements of the detector are proposed, the hardware circuit and software algorithm of the detector are designed, and the functional performance tests of smoke and temperature sensing are carried out according to GB4715 and GB4716. The results show that the designed detector can collect smoke and temperature information at the same time, process and send action signals through data analysis and functional algorithm, and the functional performance meets the requirements.
