The sensor is powered on regularly, after the sensor transmits the data acquired by the sensor to the processor 1, namely the sensor does not transmit the acquired data to the processor 1, the processor 1 immediately controls the power management module 6 to stop supplying power to the sensor, so that the sensor can work regularly, different acquisition frequency requirements of users are met, and power consumption can be further reduced.
The processor 1 of this embodiment is provided with two working modes, namely, active polling and active reporting, for periodically reading and processing data collected by the sensor, and transmitting the collected data to the server in the form of a data packet through the wireless module 2. Specifically, in this embodiment, the acquisition frequency of the sensor is set to be 1 h/time, and the power supply time to the sensor is 15s during each acquisition, so that the sensor can be powered for 5.35 years according to the electric quantity of the power supply 3, thereby greatly reducing the power consumption of the wireless deployment device.
