Remote irrigation control method and system

Abstract

The invention relates to a remote irrigation control method and system. The method comprises following steps: judging the 4G signal strength by a centralized control station; when the 4G signal strength is strong enough for data transmission, sending a work command to all centralized control stations by a cloud server through 4G transmission; when the 4G signal strength is not strong enough for data transmission, sending a work command to all centralized control stations by the cloud server through a network bridge; receiving the work command by the centralized control stations; receiving a water pump starting command by a pump station, and starting a water pump. A field to be irrigated is provided with a plurality of center pivot sprinkling machines. The cloud server can send a work command to the centralized control stations of all center pivot sprinkling machines. When the 4G signal around the centralized control stations is not stable, communication between the centralized controlstations and the cloud server is established through a network bridge so that centralized control stations of all center pivot sprinkling machines can receive the work command from the cloud server. Remote control and management of irrigation are realized, and the labor strength is reduced for farmers.

Description

technical field [0001] The invention relates to the field of remote irrigation control, in particular to a remote irrigation control method and system. Background technique [0002] There is a large area of ​​cultivated land in our country. In the cultivation of agricultural crops, it is necessary to irrigate the crops to promote the growth of the crops and replenish the water needed for the growth of the crops. The central pivot type sprinkler is also called the pointer type. The rotating shaft of the sprinkler is fixed in the center of the irrigation area, fixed on the reinforced concrete support, and the upper end is connected with the rotating elbow through the rotating mechanism (collector ring), and sprays water to the crops through the spraying system on the truss. Water-increasing irrigation machinery. At present, my country's agricultural development has tended to be automated and intelligent.

In the cultivation of agricultural crops, it is necessary to irrigate the crops to promote the growth of the crops and replenish the water needed for the growth of the crops. The central pivot type sprinkler is also called the pointer type. The rotating shaft of the sprinkler is fixed in the center of the irrigation area, fixed on the reinforced concrete support, and the upper end is connected with the rotating elbow through the rotating mechanism (collector ring), and sprays water to the crops through the spraying system on the truss. Water-increasing irrigation machinery. At present, my country's agricultural development has tended to be automated and intelligent. Multiple irrigation machines are controlled by 4G transmission for sprinkling irrigation. However, due to the area to be irrigated reaches tens of thousands of acres, the 4G signal coverage near some sprinkler irrigation machines is not good. Establish communication with cloud server through 4G
