Embodiment Construction

[0031] In the present invention, as the bottom unit of the whole control system, PLC plays an important role in the data collection and processing of the whole control system. It completes the collection of soil moisture data, and converts the collected soil moisture data through the A / D conversion module. The converted data is processed by fuzzy control technology, and the output signal is sent to the solenoid valve module to realize the purpose of automatic irrigation. At the same time, the upper computer module monitors the internal data of the PLC in real time.

[0032] A kind of irrigation method of fuzzy irrigation control system based on PLC, comprises the following steps:

[0033] S1: According to the soil moisture information detected by the soil moisture sensor, determine whether watering is required;

[0034] S2: According to the water level information of the reservoir detected by the water level sensor, when the water level of the reservoir is lower than the mini...

Abstract

The invention discloses a programmable logic controller (PLC)-based fuzzy irrigation control system and an irrigation method thereof. The system comprises a PLC controller, a power supply module, a sensor module and a photovoltaic pump, wherein the sensor module is connected with the PLC controller; the power supply module is used for supplying power for the PLC controller and the photovoltaic pump; an output end of the PLC controller is connected with the photovoltaic pump by means of an electromagnetic valve; the electromagnetic valve is connected with a fuzzy-PID controller used for controlling the opening degree of the electromagnetic valve for performing irrigation. The PLC controller is used as a control core, and a fuzzy control technology is used for controlling the crop irrigation, so that the system cost is lowered, and the irrigation production benefit is increased; the PLC-based fuzzy irrigation control system is high in stability, strong in anti-interference capability andlong in service life.

Description

【Technical field】 [0001] The invention belongs to the technical field of automatic irrigation, and in particular relates to a PLC-based fuzzy irrigation control system and an irrigation method thereof. 【Background technique】 [0002] At present, most of my country's farmland irrigation uses water pumps and other equipment for drainage and irrigation or sprinkler irrigation. In greenhouse cultivation of crops, uncontrolled drip irrigation is used. In the above irrigation methods, most of them need manual operation, or control the switch water valve by timing method, which may cause crop drought due to untimely watering, or excessive watering will cause a lot of waste of water resources. In addition, the power of the water pumps for agricultural irrigation is relatively large, and electric energy needs to be provided. Usually, the areas that need to be irrigated in the vast rural areas of our country are far away from the agricultural power grid, and special lines need to be ...
