Embodiment Construction

[0018] Such as figure 1 Shown, the planning method of a kind of static Zigbee network that the present invention provides, comprises the steps:

[0019] Step 1, configure the Zigbee wireless node as three types of wireless nodes: coordinator node, router node and terminal node;

[0020] Step 2, measuring the effective communication distance of wireless nodes in the installation environment of Zigbee wireless network;

[0021] Step 3, according to the monitoring area of ​​the Zigbee wireless network and the effective communication distance, set the number and position of router nodes in the Zigbee wireless network, so that each router node can communicate through one-hop or multi-hop data packets, and The wireless signal of the Zigbee wireless network can cover the entire monitoring area;

[0022] Step 4, set up the Zigbee tree-like network topology structure according to the quantity and the position of the router node, and determine the parent-child relationship of each rou...

Abstract

The invention discloses a planning method for a static Zigbee network, which comprises the steps of configuring Zigbee wireless nodes as three types of wireless nodes; measuring an effective communication distance in an installation environment; setting the number and positions of router nodes; establishing a Zigbee tree-shaped topological network structure; allocating a network address to each router node and an address pool of management; and allocating a network address and an extended address to a terminal node. According to the planning method, the static tree-shaped topological structure is established; limitation to the layer number is overcome; meanwhile, the two-byte extended address is used for distinguishing the terminal node; network capacity is greatly improved; and an application range of a monitoring network is expanded.

Description

technical field [0001] The invention relates to a wireless network planning method, in particular to a static Zigbee network planning method. Background technique [0002] At present, in the existing Zigbee protocol, according to the address calculation method of the Cskip algorithm, its network depth is up to 16 levels, beyond which the address cannot be obtained; the DAAM mechanism is used to assign addresses to all network nodes, and the maximum number of layers is set limit. However, when the application scope of the monitoring network is expanded, or when the terrain is complex, it is difficult to achieve full coverage of the monitoring area. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing Zigbee protocol is difficult to meet the network coverage requirements of a large-scale and complex terrain environment. [0004] In order to solve the above-mentioned technical problems, the invention provides a ...
