Energy-saving method for distributed self-adaption industry wireless network

Abstract

The invention relates to a distributed self-adapting industrial wireless network energy saving method for reducing the energy consumption of nodes in industrial wireless monitoring network, belonging to industrial wireless communication technology field. The energy saving project comprises: sorting all devices in the whole wireless network into node device (ND) for acquiring and sending data, energy manager for gathering and transmitting data and managing the energy consumption of the node devices, and gateway (GW) for communicating between the wireless network users and transferring monitoring data and energy managing data. By using energy manager to control the energy consumption of each node, the method provided in the invention enable the industrial wireless network to prolong network life cycle, adjust the dormancy time of the node self-adaptingly and enlarge the information amount of wireless messages, consequently, reduces the energy consumption of nodes in industrial wireless monitoring network and furthest reduces communication energy consumption.

Description

technical field [0001] The invention belongs to the technical field of industrial wireless communication, relates to a node energy-saving technology in industrial wireless communication, and is used for reducing energy consumption of nodes in an industrial wireless monitoring network. Background technique [0002] Industrial wireless monitoring network is the application of wireless communication technology in the industrial field. Battery power supply is a common way to supply power to wireless communication nodes, but the battery energy is limited. If the energy consumption problem of nodes cannot be solved, the life cycle of the wireless network will be affected. , especially in the harsh conditions of the industrial site, it is very difficult to replace the battery, and the life cycle of the network becomes more important. [0003] There are many ways to improve the entire network lifetime in wireless sensor networks, such as the literature FanYe, Gary Zhong, Songwu Lu, ...

Problems solved by technology

For example, Ren C.Luo Fellow, IEEE, Liang Chao Tu, OgstChen "An Efficient Dynamic Power Management Policy on Sensor Network" Proceedings of the 19th International Conference on Advanced Information Networking and Applications (AINA'05) 1550 445X 2005IEEE. Using node sleep Energy saving, five sleep modes are proposed, but it does not mention the mode that the radio frequency part sleeps while other parts work, because it does not perform radio frequency sleep in the data collection, storage, and parameter calculation stages, which affects the energy saving effect

[0005] The energy-saving technologies proposed in the prior art are all wireless sensor network technologies. For industrial wireless networks, there is no application in this area. In addition, the above-mentioned technologies are all energy-saving achieved in a separate way. How to adopt a comprehensive Yes, there is no complete solution for the energy-saving method combining various technologies and the corresponding energy management mechanism
