LoRa wireless remote transmission system

LoRa technology is an ultra-long-distance low-power data transmission technology based on 1GHz and below released by the American semtech company. LoRa technology is applied to remote meter reading of water meters. The first-level meter reading distance between the concentrator and the water meter is about 1km. Through up to five-level relay routing, the farthest meter reading distance is about 5km. The system follows the data transmission management mode of the three-level structure of the line remote meter reading system and the two-level transmission. The system can monitor the water volume data, valve status, abnormal alarm and other meter status of the terminal meter online in real time.
