The invention is applied to an automatic wireless meter reading system composed of a central station, a concentrator and terminals. First, each terminal makes the competition testing to determine which terminal can carry the reliable communication with itself and stores the addresses of these terminals. Then, the concentrator collects the reliable connection information of the each terminal as well as builds and stores the reliable connection information table. Finally, the concentrator builds and stores the route tables and the establishment status table of each terminal route. The inventionrealizes the automatic wireless communication between the concentrator and the terminals, and reduces the hand labor greatly as well as lowers the managing cost.
