The processing module carries out certain processing operation on the pulse value obtained from the sensor, and judges whether the equipment runs normally or not by judging whether the pulse value reaches a set threshold value or not with the temperature value set by a user. The device wakes up once every ten seconds to sample, and after the sampling is completed, the device will continue to sleep. If the sampled temperature value exceeds the set temperature threshold value or reaches the sending period, sending temperature and alarm data to the background through the wireless module, and helping maintenance personnel to better judge the running state of the equipment so as to find equipment problems more quickly.
After the data is analyzed, the data is temporarily stored in the memory of the device. When the number of samples has reached the transmission period, or the parameters of the read sensor exceed a preset value, the device will transmit data to the background via the wireless module. The adopted wireless module is an NB module, the module has small volume, low development cost and lower transmission power consumption, and is particularly suitable for the low-power consumption scene.
