Research On Control System Of Water Saving Irrigation In Modernized Agriculture Facilities

The phenomenon of wasting water in agriculture in our country is serious and the efficiency of using water is very low. A automatic irrigation control system used in installed agriculture will be introduced. It is small,low-cost ,simple and stable. According to measurement and the nature of the crop in requirement of water, the soil moisture and temperature can be measured. In order to save water in high efficiency, it can irrigate timely and precisely. The irrigation control technology enable the people to get rid of the tradition all to depend on the experience the irrigation pattern. The irrigation goal of highly effective saving water have been achieved .It is very the count for much that the phenomenon of short water in agriculture in our country have been alleviating .This control system has great significance for saving water , producing in high quality and developing the modern agriculture.The automatic control system of saving water irrigation is designed to use the Sensor technology and the monolithic integrated circuit technology, industry observation and control technology and agricultural planter and irrigation technology union method. Two aspects is mainly included. One is measured, namely the gain soil moisture information, and needs the water characteristic according to the soil moisture information and the crops to decide the irrigation time and irrigation quantity how many. This formerly only the irrigation pattern will be gotten rid of which irrigated depending on the experience, caused the crops irrigation decision-making establishment above the science foundation. Two is controls, how has to study according to the soil condition, the soil moisture information and the crops needs the water characteristic to carry on the reasonable irrigation decision-making, soon the tradition depends on the experience to change by the artificial manual valve control irrigation way automatically carries on at the right moment right amount, according to needs the precise irrigation control. The entire control system mainly has four modules: examination module, data processing module, digital module and control module. Revolves these four big modules to carry on the following work: The soil moisture measurement system design, the soil temperature measurement system design, controls the instrument the design and so on.Through the laboratory, really the test result indicated that, the automatic control irrigation system of saving water is able to determine the soil the moisture content and the temperature, according to supposes the set point control irrigation, the entire control system could the normal work, realize, according to has at the right moment needed the precise irrigation, achieved highly effective saving water goal.
