Description

technical field [0001] The present invention relates to wireless communication technology, specifically an industrial wireless communication method based on IEEE 802.15.4. Background technique [0002] Compared with wired networks, wireless networks have the characteristics of no wiring, easy maintenance, high flexibility, and fast implementation, which is undoubtedly a huge advantage for industrial applications. With the maturity of wireless communication technology and the reduction of cost, industrial network wireless has become one of the trends. A typical industrial wireless measurement and control network such as figure 1 As shown, a large number of wireless sensor nodes are distributed in various monitoring points of the industrial site, and these nodes form a network together with nodes with routing functions, and the on-site monitoring data is transmitted back to the gateway device node in a multi-hop manner. While the wirelessization of industrial networks brings ...
