Abstract
This paper have a study of the wireless group control system applied in plantation irrigation system. China is a fresh water resources scarce country, agricultural irrigation occupies a large part of the water resources. Because long-term use of traditional farming patterns, low utilization rate of irrigation water, irrigation water wasted is a very serious problem. In order to improve the irrigation efficiency and spare the water resource, based on an example of a large plantation in Shandong Province, this study designs a wireless group control system according to the specific situation of the irrigation wells dispersed. It realizes the communication between the main control room and 13 dispersed wells through wireless network. In the distributed sub-stations, we use the Frequency Converter to drive the lift pump to achieve the precise allocation of irrigation water, the saving effect is significant. Besides, the paper especially introduces the software realization of the wireless communication.
Highlights
China is a fresh water resources scarce country, the per capita water amount accounts for only 1/4 of the world
We open up the thinking and apply the wireless group control system to the irrigation projects in the plantation, put it into practice (Ding, 2010)

Summary
China is a fresh water resources scarce country, the per capita water amount accounts for only 1/4 of the world. In order to improve the irrigation efficiency and spare the water resource, based on an example of a large plantation in Shandong Province, this study designs a wireless group control system according to the specific situation of the irrigation wells dispersed. It realizes the communication between the main control room and 13 dispersed wells through wireless network. The main control room issued substation pumping values to the various sub-station controllers according to the water demand and the actual supply of water in the plantation.
