Research based on real time monitoring system of digitized agricultural water supply

Abstract

Real time monitoring system of digitized agricultural water supply is a complex engineering. In this paper, the software and hardware design principal of real time monitoring and management system in water resources and the integrated characteristics of structure are introduced. The general planning of real time monitoring system in integrated system in agriculture water supply is proposed. This system, which is based on info technology and relies on computer technology, remote controlling and automatic technology, collects, transports and processes the water resource and its related info in the managed area in real time. The water resources are dispatched and distributed using scientific decisive mathematical model. The whole structure of the system can be divided into three parts: central management system, wireless communication net and enterprise subnet system. Some critical problems are discussed and demonstrated fully. This system has advanced performance and applicable prospect. The great social and economic benefit has been created by using real time monitoring system of agricultural water supply in the North area in Shandong province, China. By contrasting the year of 2005, the effect of conventional analysis is that the volume of scarcity of water in agricultural water supply system reaches 49.16 million m3. While the volume of scarcity of water is 35.48 million m3 by scientific management, so the volume of scarcity of water decreases 13.68 million m3. This means that we can save 13.68 million m3 water every year by optimizing the existing water resource. So it is necessary to dispatch the existing water resource scientifically on time and space, and the profit is great. The system has opened a new way for agriculture in China.
