A Micro-Power Wireless Communication Method and Device for Local Detection and Control

A micro-power wireless communication method for local detection and control, which has been awarded two invention patents by State Intellectual Property Office of the People's Republic of China(Patent No. : ZL200510041064.7 ; No : ZL200710162785.2), includes forming star topological dynamic tree structure by setting relay with each node using micro-power to emit and receive signal, using time delay and identification mark to shield the other channel to form the only dynamic transmission channel between root node and leaf node at certain time for realizing signal transmission. The device for realizing the method is also disclosed. By setting two groups of eight switches, various nodes in the hierarchical structure may use same devices, resulting in advantages of low cost, simplicity and universality.
