Remote variable frequency irrigation monitoring system based on ZigBee and general packet radio service (GPRS)

Abstract

The invention discloses a remote variable frequency irrigation monitoring system based on ZigBee and general packet radio service (GPRS). In the prior art, wires are arranged complexly and are difficult to extend. The system comprises a field monitoring part and a remote monitoring center, wherein the field monitoring part comprises a data acquisition node, a frequency converter control node, an electromagnetic valve control node and a field convergence node; a wireless ZigBee communication protocol is adopted in the communication of the field monitoring part; the remote monitoring center consists of a personal computer (PC) machine and monitoring software; the data acquisition node, the frequency converter control node and the electromagnetic valve control node are used for acquiring theinformation of an irrigation field, and the information is transmitted to the field convergence node and transmitted to the remote monitoring center through a GPRS network; the remote monitoring center is used for displaying the information of the irrigation field in real time and accurately controlling the irrigation by controlling the frequency converter control node and the electromagnetic valve control node; and the system realizes unmanned remote irrigation monitoring by combining the ZigBee technology and the GPRS technology.

Description

technical field [0001] The invention relates to the technical field of agricultural water-saving intelligent irrigation, in particular to a remote monitoring system for variable frequency irrigation based on ZigBee and GPRS. Background technique [0002] my country's water resources are already in a state of shortage, of which agricultural water consumption accounts for about 75% of the total water consumption, but at present the utilization rate of agricultural irrigation water in my country is only 45%, and the waste phenomenon is serious. It is imperative to develop automatic paste water-saving irrigation technology must do. With the rapid development of electronic information technology, automated water-saving irrigation systems have been greatly developed. In the traditional irrigation monitoring system, the two-level system consisting of the upper computer and the lower computer is mostly used in the wired connection mode. The lower computer is generally an embedded si...

However, the wiring of such systems is complex and difficult to move

Especially when the monitoring range is large and there are many sensors and control nodes, it will be very difficult to install and move the wiring, and the large-scale wiring is also an expensive investment.
