Wireless remote gas meter communication function

1. Ultra-long communication distance:

     A. Using the latest spread spectrum technology SX1278 wireless chip, the coverage in sparse environment can reach 8 kilometers, and it can also reach 2 kilometers in dense environment;

     B. The actual receiving sensitivity reaches -129.5dBm;

2. Wireless routing function:

     A. With two-way communication function, it can undertake the task of forwarding data;

     B. The maximum routing level is 8, and the signal coverage is wide;

     C. Multiple backup paths to automatically balance the power consumption of intermediate nodes;

3. Wireless automatic networking function:

    A. Automatically search for surrounding nodes without manual intervention, and the system debugging is simple;

    B. The networking time is short;

    C. When the route in the table fails, the node autonomously initiates the re-entry process;

4. Real group copy function can be realized:

    A. The entire network is awakened in a unified manner to realize the real meaning of group copying;

    B. Precise clock control to ensure orderly return of data;

    C. Reasonable TDMA (Time Division Multiple Access) backoff algorithm to reduce the probability of data collision;

5. Simplified installation of centralized meter reading equipment:

    A. The number of concentrators and repeaters is greatly reduced (according to empirical estimates, for a community of 2,000 households, only one concentrator can be installed to cover the entire community);

    B. The requirements for the installation location of the concentrator are reduced;

    C. The debugging of the system is relatively simple.
