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...

Abstract

The invention discloses a wireless meter reading method and system. The method and the system are used for forming a multichannel wireless meter reading system and avoiding the influence on power consumption of meters caused by being awoken frequently. The wireless meter reading method disclosed by the invention comprises the steps: first links between the meters and collectors or concentrators carry out wireless communication by adopting a first frequency point; second links between the meters and the collectors or concentrators carry out wireless communication by adopting a second frequency point; third links among the collectors and between the collectors and the concentrators carry out wireless communication by adopting a third frequency point.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless meter reading method and system. Background technique [0002] The traditional manual meter reading method has many disadvantages, such as high labor intensity, low efficiency, high management cost, and reading errors. With the emergence and development of wireless sensor networks, the application of wireless sensor network technology to meter reading systems has achieved Extensive research and application, the use of wireless meter reading can effectively solve the disadvantages of manual meter reading. [0003] At present, in the remote meter reading industry such as water meters and gas meters, remote wireless meter reading is a well-known problem. Because there is no mains electricity, batteries can only be used for power supply. At present, the micro-power wireless technology based on the FSK 433 / 470MHz frequency band is widely used, and the CC1100 or SI100...
