In the monitoring alarm using process, the main control module can receive the alarm signal transmitted by the monitoring protection device through the Bluetooth communication module.
Because the Bluetooth communication has the characteristics of high transmission rate and low power consumption, point-to-point transmission can be realized. Therefore, based on the Bluetooth communication module, the point-to-point communication between the monitoring alarm device and the corresponding monitoring protection device can be realized, and a higher transmission rate is kept.
