A serious lack of water resources in China, accounting for 80% of total water consumption and waste water for agricultural use is very common.further aggravate the water shortage problems.Meanwhile, traditional irrigation methods and crops on soil moisture in light of the demand characteristics of the different irrigationnot the best environment for the growth and crop growth cycles, thereby affecting the crop harvest.Human duplication of investment, backward infrastructure, extensive management, causing tremendous waste of human resources, the waste of water resources.Higher crop harvest is not a series of problems.

       


        (System Operate Interface)


　　 The automatic watering systems can automatically monitor soil moisture and crop water requirement under the operational control of the irrigation system,achieve energy savings of manpower, water saving, the effect of increased crop harvest。
　　 The automatic watering system is divided into three subsystems : Acquisition System for monitoring subsystems, and control subsystem.
　　· Acquisition of equipment acquisition subsystem through real-time acquisition of farmland scene all the basic information.
　　· The transmission subsystem based monitoring system to collect data and crop water requirement making.
　　· Control subsystem based on the monitoring system and controlling the exercise machine with automatic irrigation purposes.
　　 Embedded systems using the embedded control system hardware and software form a complete industrial control computer systems.with data acquisition, sequential control, PID control, and man-machine interface configuration, network communications, and other functions.Embedded control of the stations as well as the embedded Linux operating system developed by the embedded control system configuration softwareIntegrated PLC control, PID control, and man-machine interface and other functions.fully consider the characteristics and the optimization of embedded systems, which occupied the whole software system resources small,operational speed, but it also has powerful functions and excellent scalability.

Both manual and automatic control systems supported :
　　 In manual mode, can be arbitrary to the remote switching solenoid valve and pumps, irrigation to control whether those stations for irrigation,those sites do not irrigation.In this way, managers can play to their rich experience in irrigation, irrigation prior to the beginning of time.Each station continuation of irrigation, irrigation,Each station crew activated the irrigation methods and the basic parameters for each station into a central controller.thus the preparation of a set of procedures and issued the directive will automatically open and close the unit in accordance with the order of rotation for irrigation。
　　 In automatic mode based on soil moisture can control solenoid valve switching, thereby realizing unmanned automatic irrigation.In this manner, the system not directly involved, the acquisition subsystem will be irrigated areas (such as :soil moisture, etc.) transmitted to the system, through a pre-established control procedures and work out an extension of time for irrigation water.Irrigation and other variables, and issued instructions, the system automatically according to a certain order of rotation for irrigation.
　　 The irrigation system is a flexible way : through the support of friendly interface, managers can set up different parameters.proceed in a different way for irrigation.
　　 Since the ability to maintain a strong system :For the misoperation caused by the operation of the system or for other reasons of the damage,systems of prevention and self-maintenance capabilities.If the whole system : voltage and current overload protection device; Each of the stations are equipped with insurance switch;In the absence of irrigation sites can under the circumstances, the pump can not be opened; pipes are installed in both the main pressure relief valveThe pressure in the pipeline to ensure security inside.
　　 System also supports remote control function : Internet,management of the system can be realized in any place custody and control.Meanwhile, a number of sub-system control center can be in any one of those sub-control system control center.

　　Lead levels：Irrigation water technology and management systems to achieve a more advanced level at home and abroad.
　　Scientific efficiency：According to the crops needed water system environment for the growth characteristics of crops and irrigation systems to control,create more suitable for crop growth cycle of the small environment, improve production efficiency of labor, increase production and increase their income.
　　 Conservation：System to overcome the drawbacks of the traditional flood irrigation, conservation of water resources.Liberate a lot of duplication of human input, saving manpower resources and reduce the costs of agricultural production.
　　 User-friendly：System is a good man-machine interface, simple and easy to administer and operate.
　　 Quick time：The introduction of a real-time system for monitoring crop growth environment, and based on the actual situation, implementation of real-time decision-making, real-time control.
　　 Remote Control：With the system Internetconnection，facilitate management remote control.
　　 Highly modular：Modular system, structural design, enhanced system reliability, but also to facilitate future system upgrades.to upgrade and expand to meet automatic irrigation has been improved and meet the requirements of development.
　　 Flexibility：System according to the different crops and water demand characteristics make a decision at any time in accordance with the actual implementation of the results,Irrigation water levels and weather changes in the factors affecting the user's requirements and the introduction of amendments and adjustments, active management.

This automatic irrigation system is suitable for many kinds of places:
　1）：The farmland irrigates
　2）：The botanical garden irrigates
　3）：Green irrigates
　4）：Industry and mining dustproof
