Communication setting modification method for wireless communication networking

Abstract

The invention discloses a communication setting modification method for wireless communication networking. The method comprises the steps that a host sends a pre-modification instruction to each slave after determining that all slaves can communicate with itself, the slave stores the pre-modification instruction and returns a first response signal to the host after receiving the pre-modification instruction, meanwhile starts a timing operation, and modifies an own personal local area network ID and / or channel according to a new personal local area network ID and / or channel information after the timing time reaches a preset delay time, then the host confirms whether the first response signals sent by all slaves are received, and if not, the host resends the pre-modification instruction to the slave that does not send the first response signal. According to the invention, it is guaranteed as much as possible that the routing slave forwards the pre-modification instruction to the remote slave before modifying its own personal local area network ID and / or channel, that is, it is guaranteed as much as possible that the pre-modification instruction is sent to all slaves to avoid the occurrence of the ''islanding phenomenon'', and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of wireless communication networking, in particular to a method for modifying communication settings of a wireless communication networking. Background technique [0002] Wireless communication networking technologies are widely used today, for example, ZigBee is a low-power, low-cost, and high-reliability wireless communication networking technology. ZigBee adopts self-organizing network and dynamic routing to establish and maintain the network, and uses PANID (Personal Area Network ID) to distinguish each independent network. Networks under different PANIDs can operate independently without interfering with each other. [0003] Since the devices in the wireless communication network need to be in the same personal area network ID and channel to perform complete communication. When the wireless signal of the master cannot directly radiate to the remote slave, other slaves are needed for routing and relayin...

AI Technical Summary

Problems solved by technology

When for some reason it is necessary to modify the personal area network ID and / or channel of all slaves in the wireless communication network, if the routing slave immediately switches to the new personal area network ID and / or channel after receiving the setting command, a The routing slave first receives the modification instruction to switch to a new personal area network ID and / or channel, so that the routing slave and the distant slave personal area network ID and / or channel are different, which will cause the remote The slave machine can no longer receive the modification instructions relayed by the routing slave machine, resulting in the failure of the modification, which is the "island phenomenon"
