Manual control
All operations of the system are done manually, such as the opening and closing of pumps, valves, the length of irrigation time, when to irrigate and so on. The advantage of this type of system is that the cost is low, the technical content of the control part is not high, it is easy to use and maintain, and it is very suitable for promotion in the vast rural areas of our country. The disadvantage is that the convenience of use is poor, and it is not suitable for controlling large-scale irrigation.
Fully automatic control
The system does not require direct participation of human beings, and can automatically open and close the water pump for a long time and automatically irrigate according to a certain rotation sequence through the pre-programmed control program and certain parameters reflecting the water demand of crops. The role of people is only to adjust the control program and overhaul the control equipment. In this system, in addition to irrigators, pipes, fittings, water pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensor, temperature sensor, pressure sensor, water level sensor, rain sensor, etc.) and wires.
semi-automatic control
There is no sensor installed in the irrigation area in the system, and the irrigation time, irrigation amount and irrigation cycle are all controlled according to the pre-programmed program, rather than the feedback information of crop and soil moisture and meteorological data. The degree of automation of such systems varies, and some parts are automatically controlled, and some parts are automatically controlled.
