IC card wireless Lora gas meter performance characteristics:
1) Strong timeliness: The data management center maintains real-time connection with every gas meter and data collection point. It can effectively meet the real-time requirements of the system for data collection and transmission;
2) Automatic networking: The concentrator automatically searches for surrounding nodes without manual intervention, with short networking time, simple system debugging, and easy operation; When the routing table in the table fails, the node will initiate the process of re entering the network autonomously;
3) Remote control: It can achieve remote control of gas meters, including data reading, parameter adjustment, switch control, and other operations;
4) Wide range of data collection: GPRS has a wide coverage area, unlimited expansion, and unlimited access locations. Can meet the access needs of mountainous areas, townships, and cross regional areas;
5) GPRS transmission has high data security and accuracy, without specialized wiring, low initial investment, quick results, and low upgrade and maintenance costs in the later stage; And the equipment is easy to install and maintain;
The wireless remote transmission gas meter has automatic networking and routing functions, greatly saving the installation quantity of collectors
