A method for modifying communication settings of a wireless communication network

Abstract

The invention discloses a communication setting modifying method of a wireless communication network. The communication setting modifying method comprises the following steps of enabling a host to set into broadcast personal local area network ID (identification) by self, sending a broadcast modifying instruction to a slave machine which can communicate with the host, controlling to modify all slave machines into the broadcast personal local area network ID, and receiving a first response signal which is returned after each slave machine is modified into the broadcast personal local area network ID; enabling the host to obtain the number of route levels of each slave machine according to the sequence of received first response signals in the communication process of each slave machine; enabling the host to gradually send the modifying instruction to the corresponding slave machine according to the increasing sequence of route levels, wherein the modifying instruction includes new personal local area network ID and / or channel information, so as to enable each slave machine to modify the self personal local area network ID and / or channel according to the new personal local area network ID and / or channel information, and return a second response signal to the host. The communication setting modifying method has the advantages that the modifying instruction is sent to the host from far to near, the generation of island can be avoided, 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"
