Abstract:

In order to improve the detecting precision and the response time of the electrical fire detection system, the wireless infrared temperature measurement system based on STM32F, was designed on the basis of the traditional electrical fire detection system. Infrared temperature measurement technology was used in this system to detect the temperature signal of the electrical power distribution box. Temperature signal and A/D converted data were real-time collected by the microprocessor, then data process and algorithm analyses were proceed. And use the ZigBee wireless network technology to form a network that could realize the reliable transmission of temperature data. It shows that the electrical fire wireless infrared temperature measurement system has a high sensitivity through the experimental results. The accuracy of wireless infrared temperature measurement system is up to 99.37% and the response time is 20.5 s. It can precisely detect the temperature of electrical distribution box and prevent the electrical fire.
