Power adjustment method for WIA-PA wireless network

Abstract

The present invention relates to a power adjustment method for a WIA-PA wireless network. According to the method, firstly, a WIA-PA wireless network is established, and whether the current WIA-PA wireless network is a long period type wireless network or not is judged. If the current WIA-PA wireless network is a long period type wireless network, the power adjustment is completed according to the long period type power adjustment method of the WIA-PA wireless network. If the current WIA-PA wireless network is a short period type wireless network, the power adjustment is completed according to the short period type power adjustment method of the WIA-PA wireless network. According to the technical scheme of the invention, the power adjustment and control of wireless equipment in the network is realized, and the stability of the communication link is ensured. Meanwhile, the energy consumption is saved. The energy consumption can be balanced under different temperature environments. The service life of battery-powered wireless equipment in the network is prolonged. Meanwhile, the interface among different WIA-PA wireless networks or the interface of the WIA-PA wireless network on other wireless networks adopting the 2.4 GHz ISM frequency band is reduced.

Description

technical field [0001] The invention relates to industrial wireless sensor network technology in the field of communication, in particular to a power adjustment method suitable for WIA-PA wireless network. Background technique [0002] Industrial wireless sensor network technology is widely used in industrial sites. At present, the main industrial wireless sensor network technology WIA-PA wireless network, Bluetooth, WIFI, Zigbee, WirelessHART and other private protocol wireless networks all use the 2.4GHz ISM free frequency band. However, the 2.4GHz ISM free frequency band has limited frequency resources, which leads to WIA-PA wireless network and WirelessHART adopting CSMA-CA carrier sense multiple access / collision avoidance method and TDMA time division multiple access technology to expand communication resources and avoid interference; Bluetooth, WIFI , Zigbee, and other proprietary wireless networks use only the CSMA-CA carrier sense multiple access / collision avoidance...
