Embodiment 1
[0019] The embodiment of the present invention firstly discloses a wireless meter reading method, and the method is applied in a mixed networking system of concentrators and collectors. In this system, concentrators, collectors and meters communicate wirelessly, and the corresponding network structure is as follows figure 1 As shown, both the collector and the concentrator can be used as the gateway of a certain subnet, responsible for collecting the meter data in the subnet; and in the network topology diagram between the concentrator and the collector, as shown in figure 2 As shown, the concentrator can be regarded as the gateway of the entire system, and each collector determines which level of node it belongs to in the system according to the number of hops between it and the gateway.
[0020] In the wireless meter reading method disclosed in this embodiment, a multi-channel, multi-frequency point communication method is adopted. Specifically, it includes the following t...
