Technical Characteristics
◆The point-to-point communication distance can reach 2KM;
◆ Fully self-organizing network, automatically optimizing routing, automatically discovering and deleting nodes;
Under the spread spectrum reception mode, the maximum reception sensitivity of the wireless module can reach -148dBm;
◆ Adopting spread spectrum modulation with strong anti-interference ability, ensuring effective and stable data transmission;
◆Without replacing the existing mechanical water meter, remote data transmission can be achieved by installing a wireless communication LORA module;
◆The routing function between relay modules adopts a robust mesh like (MESH) structure, which greatly increases the stability and reliability of the system's performance;
◆ Separate structure design, the water supply management department can install the ordinary water meter first according to the needs, and then install the remote transmission electronic module when there is a need for remote transmission. Laying the foundation for IoT remote transmission and smart water technology, implementing them step by step, making them more flexible and convenient.
Application Functions
◆ Active data reporting mode: Proactively report meter reading data every 24 hours;
◆ Implement time-division frequency reuse, which can copy several networks in the entire area with one frequency;
◆ Adopting a non magnetic communication design to avoid magnetic adsorption and extend the service life of the mechanical parts;
The system is based on LoRa communication technology and adopts a simple star network structure, with low communication delay and long and reliable transmission distance;
◆ Synchronous communication time unit; Frequency modulation technology avoids co frequency interference to improve transmission reliability, and adaptive algorithms for transmission rate and distance effectively improve system capacity;
◆ No complex construction wiring is required, with a small amount of work. The concentrator and water meter form a star shaped network, and the concentrator forms a network with the backend server through GRPS/4G. The network structure is stable and reliable.
