Embodiment Construction

[0026] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0027] Such as figure 1 As shown, the FPGA-based irrigation control system consists of three parts: controller 1, control panel 2, and drive circuit 3. The FPGA module 4 in the controller is connected with the communication module 5 and the control panel 2 to realize the communication with the upper computer and the control panel. The LED display and keyboard control module in the control panel 6 and the field block status module 7, the keyboard input module 8 is connected with the digital tube display module 9 to realize manual control and display. The power supply circuit 10 and the solenoid valve driving circuit 11 in the driving circuit are both connected to the controller 1 to perform irrigation operations.

[0028] The controller 1 is composed of an FPGA module 4 and a communication module 5, and is the core of the entire irrigation control system....

Abstract

The invention relates to an irrigation control system based on an FPGA (Field Programmable Gate Array), which comprises a controller, a control panel, a drive circuit and an electromagnetic valve, wherein the electromagnetic valve is used for opening and closing a pipeline, and the controller is connected with an upper computer and the control panel and used for receiving an irrigation command from the upper computer and a control command which is manually input and analyzing and processing the irrigation command and the control command, so that the drive circuit is controlled to open and close the electromagnetic valve so as to implement irrigation. According to the irrigation control system, an FPGA module is adopted, all control logics are realized through Verilog HDL (Hardware Description Language), and therefore, the irrigation control system has the advantages of user programmability, strong function and convenience in development. According to the irrigation control system, the FPGA module is adopted, the quantity of I / O pins is large, a plurality of greenhouses or fields can be simultaneously controlled to be irrigated without an additional peripheral interface circuit, the debugging is easy, and the production cost is low. According to the irrigation control system, the automatic control and the manual control can be simultaneously realized. A decision and the control command sent by a system can be received through a communication module, and additionally, the manual regulation and control can be completed through the control panel.

Description

Technical field [0001] The invention belongs to the technical field of agricultural irrigation control, and relates to an irrigation control system based on FPGA. Background technique [0002] Irrigation is a very important link in agricultural production and an important factor affecting production output. Automatic control of irrigation is an effective means to improve agricultural production. With the application of information technology in agricultural production, intelligent and efficient irrigation systems have become the direction of development. Under the dual constraints of water scarcity and ecological environment, it is of great significance to combine information technology with agricultural irrigation and develop an intelligent irrigation system suitable for the current situation of agricultural production in my country. [0003] The 2012 International Remote Sensing Conference published an intelligent water-saving irrigation system based on STC89C52 MCU. Due to the ...
