Automatic farmland irrigation system and irrigation method

Abstract

The invention provides an automatic farmland irrigation system, which is characterized by comprising a water source, a water pump, a current-carrying gate valve, a fertilizer applicator, a filter, a solenoid valve, a pressure regulator, a sprinkler, a controller, sensors and a PC. The amount of water needed for irrigation and the length of irrigation time can be adjusted by the control and sensortechnologies according to the different crop types, soil conditions, air temperature and humidity and weather conditions in different regions. The task of the sensors is to collect the the data of temperature and humidity in farmlands, the process of collection is dynamic, and the collected data is processed by a single chip microcomputer so that the values of temperature and humidity are displayed on the display screen. Eventually, the collected information is sent to the PC through a wireless module. People can irrigate farmlands by controlling the PC, and the human-computer interaction function is achieved very well.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to an automatic farmland irrigation system and irrigation method. Background technique [0002] my country has been a large agricultural country since ancient times. In the past, the irrigation methods were very simple, basically relying on artificial irrigation. It was not until modern agricultural facilities were developed. But the effect is not too obvious, and there are only a few kinds of crop irrigation methods that can provide people with convenience. Such as irrigation, drip irrigation, flood irrigation, drip irrigation, etc., but the water utilization rate is not high, such as droppers, the water utilization rate is only 40%. Low water utilization rate is the biggest problem of all irrigation methods. Although some technologies have been applied to improve the utilization rate of water resources, they have not solved the problem from the root. For example, in the pr...

Problems solved by technology

However, the irrigation automatic control equipment imported from abroad is designed according to the specific conditions of their own country, and does not take into account the weather and soil conditions of our country.

Moreover, the types of crops in our country are not all the same as those in other countries, so we cannot give full play to its advantages

Due to the high cost of introducing a complete set of equipment, it is urgent to develop an automatic irrigation control system that is affordable and in line with our country's conditions.
