Farmland irrigation and drainage control system

Abstract

The invention discloses a farmland irrigation and drainage control system which comprises a detection module, a manual control module, an irrigation module and a discharge module, wherein the detection module is mounted in a farmland, the irrigation module is mounted at a water inlet of the farmland, the discharge module is mounted at a discharge port of the farmland, a frequency converter A on anirrigation water pump is electrically connected with a processor, and a frequency converter B on a discharge pump is electrically connected with the processor. According to the system, the detectionmodule comprises a rainfall monitoring module and can detect rainfall in raining, irrigation and drainage are automatically implemented by the system when raining is absent, manual operation is omitted, automation degree is high, the control module controls the irrigation module to irrigate crops according to the rainfall in raining, the irrigation water pump is closed in advance, irrigation wateris reduced, water resources and power sources are saved, the system is more environmentally friendly, the power of a discharge water pump is increased to discharge water according to the rainfall when water is discharged, damage caused by high-level water to the crops is avoided, and growth of the crops can be facilitated.

Description

technical field [0001] The invention relates to an irrigation and drainage control system, in particular to a farmland irrigation and drainage control system. Background technique [0002] As a large agricultural country, our country has made great progress in the construction of agricultural infrastructure. Agricultural irrigation and drainage are closely related to the growth and development of crops. Most of our country is located in subtropical regions, which is the basic condition for our country to be able to grow rice in large areas. However, due to my country's climate is hot and rainy in summer, and the area where rice is grown has a lot of rainfall and evaporation. Therefore, irrigation and drainage facilities are extremely important to the majority of growers. [0003] The irrigation and drainage control system in the prior art has the following defects: when the water level in the farmland is lower than the normal water level, the control system in the prior art w...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of farmland irrigation and drainage control system, to solve the following defects in the irrigation and drainage control system in the prior art proposed in the above-mentioned background technology: when the water level in the farmland is lower than the normal water level, the control in the prior art The system will irrigate the farmland in time, but when it is raining, the rainwater and irrigation water will irrigate the farmland at the same time, which will easily lead to the waste of water resources. At the standard water volume, the drainage pump will be closed at this time, but the rainwater continues to irrigate the farmland, causing the water level to be too high, which will damage the crops
