Courtyard long-distance irrigation system

Abstract

The invention relates to a courtyard long-distance irrigation system. The system comprises a long-distance controller and a plurality of detection point sub-systems; data interaction is carried out between each detection point sub-system and the long-distance controller through Ethernet; and each detection point sub-system comprises a temperature and humidity detection module, a singlechip and an electromagnetic valve driver module. According to the system, one long-distance controller can control a plurality of detection point sub-systems to automatically irrigate, and the long-distance controller and the detection point sub-systems communicate with each other through Ethernet. The detection point sub-systems send acquired environmental information to the long-distance controller, and the long-distance controller sends a control command to the detection point sub-systems to control the detection point sub-systems to work. Through Ethernet communication, each detection point sub-system does not need to be connected with the controller by lines; the system cost is obviously reduced; and simultaneously, the problem that the transmission of wireless network is unstable is also solved.

Description

technical field [0001] The invention relates to the field of automatic watering, in particular to a remote system for garden watering. Background technique [0002] Agriculture is the foundation of the national economy. Reasonable agricultural water use is related to agricultural development and economic benefits. China is a large agricultural country with a large population, less arable land, and water shortage. The special climate, geography and other natural and social conditions determine that China's agriculture must follow the development of irrigated agriculture. the way. At present, surface irrigation accounts for more than 95% of the total irrigated area in my country, and it will still be the main irrigation method of my country's agriculture for a long period of time in the future. Establishing and vigorously promoting various improved surface irrigation engineering technologies is the key to improving the level of water-saving irrigation in my country. fundament...

Problems solved by technology

Although the reliability of the wireless module has been greatly improved, there will always be problems at certain times, coupled with other human factors, which may cause the disconnection of the established TCP connection, which requires the selected wireless module to support disconnection The continuous function has virtually increased the complexity and price ratio of the system. At the same time, practice has proved that this type of system is easily affected by lightning, air electromagnetic waves and power supply pollution, and has high requirements for lightning protection and anti-interference capabilities: the system There are lightning arresters connected to the transmitting antennas, which can effectively prevent lightning, but also increase the cost and complexity of the system

Moreover, there are many irrigation control points in this system, the pipe network system is relatively complex, and the data monitoring points are scattered. Various reasons have led to the lack of full development and application of wireless methods.
