The remote gateway part included in the LoRa wireless water meter reading system can also be called a concentrator or a base station. Generally, CAN2.0 Communication Module there is a base station distributed in a community, and this base station is responsible for copying the LoRa wireless water meters in the entire community.
A gateway can correspond to multiple node devices, and data collection can be realized by polling. The gateway is connected to the back-end server through standard IP. These communications can be bi-directional. The communication between the node device and the gateway is based on different communication frequencies and air transmission rates, and the selection of the air transmission rate requires a trade-off between transmission distance and message delay.
It can be seen from the above that the gateway does not process the data. The function of the gateway is to receive the data from the LoRa wireless water meter, and then transmit it to the back-end server through the operator's 3G or 4G network. At the same time, the gateway can also receive commands from the back-end server and send the commands to the LoRa wireless water meter.
The server part of the LoRa wireless water meter reading system needs to store and process data, and also includes various systems. The server mainly includes user management system, operation management system, business system, maintenance system, etc.
The functions of the user management system include adding new users, deleting and modifying old users, etc.; the functions of the operation management system include regular meter reading, water consumption statistics, table export, and user query; DC-DC isolation type the functions of the business system include payment entry And detailed statistics, low water reminders, etc.; the functions of the maintenance system include LoRa wireless water meter operation status collection and fault detection.
