Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0053] figure 1 The WIA-PA wireless network topology diagram of the present invention. The WIA-PA wireless network topology is a mixed network of MESH network and star network. The gateway device and routing device form a MESH network, and the routing device and node device form a star network. The message is sent by the node device, via the routing device, to the communication link of the gateway device or the communication link sent by the routing device to the gateway device is an uplink; the message is sent by the gateway device, via the routing device, to the gateway device. The communication link of the node device or the communication link sent by the gateway device and sent to the routing device is a downlink.

[0054] The child node device is a wireless device in the network with a single destination address, and the parent node dev...

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...
