An automatic irrigation system based on farmland moisture monitoring

Abstract

The present invention provides an automatic irrigation system based on farmland moisture monitoring, the system includes a wireless sensor network for monitoring the moisture status of crops in the farmland, and the wireless sensor network includes sink nodes and sensors randomly deployed in various places in the field Node, the sensor node collects the crop moisture status data at the monitored location and sends it to the sink node; the system also includes a data analysis device for analyzing irrigation demand based on the crop moisture status data sent by the sink node; the sensor node is connected to control the irrigation device The DC solenoid valve, and receive the signal of the data analysis device in real time; the data analysis device sends a control signal to the corresponding sensor node when the crops need to be irrigated, so that the sensor node controls the corresponding DC solenoid valve according to the control signal, opens the irrigation device, and implements Precision irrigation.

Description

technical field [0001] The invention relates to the field of agricultural monitoring devices, in particular to an automatic irrigation system based on farmland water monitoring. Background technique [0002] The existing crop moisture status real-time monitoring system also has the following obvious deficiencies: [0003] (1) The communication technology mainly adopts wired communication technologies such as serial bus technology and field bus technology. Although it has the advantages of good equipment interoperability and strong anti-interference ability, the actual application environment has long-term high temperature, humidity, soil and The air has the characteristics of high acidity and alkalinity, which can easily lead to the aging of communication cables, thereby reducing the reliability of the system; [0004] (2) The sensor works in a wired mode. In actual agricultural production applications, sensor nodes need to be densely distributed to achieve effective covera...

Problems solved by technology

[0003] (1) The communication technology mainly adopts wired communication technologies such as serial bus technology and field bus technology. Although it has the advantages of good equipment interoperability and strong anti-interference ability, the actual application environment has long-term high temperature, humidity, soil and The air has the characteristics of high acidity and alkalinity, which can easily lead to the aging of communication cables, thereby reducing the reliability of the system;

[0004] (2) The sensor works in a wired mode. In actual agricultural production applications, sensor nodes need to be densely distributed to achieve effective coverage of the monitoring area. This will lead to criss-crossing cables inside agricultural facilities, and the cost of system installation and maintenance will increase sharply.

These factors greatly limit the promotion and application of research results in actual production.
