Enterprise-class ZigBee network seamless roaming method and system

Abstract

The invention discloses an enterprise-class ZigBee network seamless roaming method, which comprises the following steps of: dividing and configuring ZigBee networks in a range pre-covered by an enterprise-class wireless sensor network, setting corresponding device identification information for each network receiver and exciter of each ZigBee network, wherein the network configuration comprises the step of distributing a corresponding network identifier for each ZigBee network, and at least saving the network identifier for each ZigBee network and the device identification information of the network in an upper computer; uploading information including the device identification information of the exciter to the upper computer through a network convergence device of the original ZigBee network via a terminal label when the terminal label triggers the exciter; and receiving the information through the upper computer, and judging whether the ZigBee network where the exciter is positioned and the ZigBee network where the original terminal label is positioned are the same network, if not, performing network switching on the terminal label.

Description

Problems solved by technology

[0007] If a single ZigBee network is used in an enterprise-level wireless sensor network, there may be the following disadvantages: (1) There are too many network nodes, nodes in the same frequency band will collide when sending data, and data delays are likely to occur; (2) Network nodes Too many, the depth of the self-organizing network is not easy to control, and the network bandwidth is not enough, there may be communication delays and data loss, which greatly reduces the stability and reliability of the network; (3) Too many network nodes, the network is too large , resulting in inconvenient system logic management; (4) In a single network, the number of effective and reliable network nodes is far from meeting the needs of practical applications
