Wireless network multichannel combination communication method

Abstract

The invention relates to a wireless network multichannel combination communication method. The method includes that S1, networking is performed on concentrators by a master station, and adjacent concentrators use different communication channels; S2, networking is performed on collectors by the concentrators, and adjacent collectors use different communication channels; S3, networking is performed on a terminal device by the collectors, the collectors use basic channels to send networking instructions in a broadcast mode to the terminal device, the terminal device receives the commutation channels of the collectors after networking succeeds, and the collectors and the terminal device are communicated with each other. The wireless network multichannel combination communication method has the advantages that multiple basic channels and wide basic channels are used for spacing, so that same frequency interference is avoided, mistaken awakening to the terminal device is prevented, power consumption of the terminal device is reduced and service life of the terminal device is prolonged; the adjacent collectors use the different communication channels, so that competition on the same channel during automatic data sending of the terminal device is lowered, real-time performance of network transmission is improved, system concurrent processing ability and system throughput are improved.

Description

technical field

[0001] The invention relates to the field of wireless network communication, in particular to a wireless network multi-channel combined communication method. Background technique

[0002] Currently, in wireless networks on the market, communication channels between devices mostly adopt a single-channel, single-frequency communication mode. The data transmission and reception capabilities of this technology are not excellent, and it is extremely prone to problems such as co-channel interference and channel competition that affect data transmission. At the same time, the data processing efficiency of this technology is also low. Multiple lower-layer devices use the same frequency to transmit data to the upper-layer device, and the upper-layer device receives all the data that can be received, and then screens and discards data that does not belong to the processing range. This processing method reduces the processing capability of the device and lowers the uti...
