[Abstract]:The Xinjiang production and Construction Corps is located in the arid and semi-arid area, and the contradiction of water resources supply and demand is prominent, which puts forward higher requirements for the development of water-saving irrigation technology. The timely and accurate collection, transmission and storage of soil moisture, environment temperature of crop growth and the feedback state of solenoid valve are very important for making the decision of automatic control of water-saving irrigation. In this paper, the current situation of water saving irrigation automation control system in Xinjiang is investigated on the spot, and the demand of field information collection for water saving irrigation automation control system is analyzed in combination with related literature analysis. The overall scheme of water-saving irrigation data collector is designed by using GSM short message communication mode. It is determined that the collector has the functions of collecting, transmitting and storing soil moisture, temperature, solenoid valve opening and closing state, as well as the opening and closing control function of solenoid valve. The data collector uses low-power CY8C29466 microprocessing controller as the core. Under the PSoc Designer development environment, C language is used to complete the main program. The communication module MC37ir3 receives the "open:1.1" short message and enters the control solenoid valve to open the interrupt program. The microcontroller transmits the control instruction to the P89LPC934 single-chip microcomputer P89LPC934 on the driving circuit board to output the high level corresponding to the pin of the solenoid valve. The boost module of the driving circuit provides the voltage for the driving solenoid head to open the solenoid valve, and the solenoid valve opens. When the pressure of the flow through the solenoid valve is greater than that of the 0.03Mpa, the current pushes the sector action mechanism of the valve position sensor. The change of the action of the valve position sensor will be sensed by the feedback signal acquisition pin of the microcontroller and enter the solenoid valve feedback signal collection interrupt subroutine. The microcontroller drives the short message module to the first control short message machine or the farmer's mobile phone. Sending the opening and closing information of the solenoid valve to realize the function of accurately feedback the opening and closing state of the solenoid valve. The data collector can detect soil moisture and temperature at predetermined intervals and send them to farmers' mobile phones in the form of short messages. At the same time, farmers can also actively send short messages of soil moisture, temperature, "query vwctempp?" When the microcontroller detects the correct short message query string, it enters the interrupt soil moisture query subroutine. After the microcontroller collects the data, the communication module automatically sends the short message of soil moisture and temperature to the farmers. If the soil moisture measured exceeds the irrigation threshold, a short message will be sent to remind farmers to stop irrigation. Through the analysis of the test results of the data collector, it is found that the data collector can accurately collect soil moisture, soil temperature, solenoid valve feedback signals and integrate the control function of the solenoid valve at the same time. At the same time, it simplifies irrigation system and saves system cost.
