Low-power-consumption wireless monitor and control system for agricultural greenhouse

Abstract

The invention discloses a low-power-consumption wireless monitor and control system for an agricultural greenhouse. The system comprises a remote Web server, a gateway and wireless monitor and control nodes. The wireless monitor and control nodes are responsible for monitoring soil temperature and humidity of a parcel and executing a control command sent from the gateway; the gateway receives data from each wireless monitor and control node and displays the data on a screen in real time, and realizes data interaction with the remote Web server through a 3G network; and the remote Web server provides a monitor and control method with which a farmer can realize remote access by utilizing a browser on a mobile phone and a computer. The wireless monitor and control nodes are powered by lithium batteries, and software and hardware can work for a long time stably by utilizing the low-power-consumption design, so that the system can be arranged at any place of the greenhouse conveniently without being limited by wiring difficulty.

Description

technical field [0001] The invention relates to the technical field of precision agriculture, in particular to a low-power wireless measurement and control system for agricultural greenhouses. Background technique [0002] At present, my country's agriculture is transitioning from the traditional intensive farming method to intelligent modern agriculture. The characteristic of intelligent modern agriculture is to realize intelligent measurement and control of the growth and development process of crops and environmental elements through various modern monitoring methods. According to specific conditions, finely and accurately adjust the utilization of various resources to obtain the highest yield and maximum economic benefits while saving resources and protecting the ecological environment. An agricultural method. [0003] The Internet of Things is called the third wave of information technology, and the application of Internet of Things technology in agriculture will greatly...

Problems solved by technology

[0005] Most of the existing systems of this type use wired methods to supply power and transmit sensor monitoring data, such as "an agricultural greenhouse temperature and humidity monitoring system" with the patent application number CN201310335933. On the other hand, most of the sensors can only be deployed around the greenhouse and the edge of the plot, which will inevitably affect the accuracy and effectiveness of the collected data

[0006] Another example is the patent application number CN201320023281 "a new type of solar wireless sensor networking system", which uses a wireless method to transmit sensor monitoring data and uses solar power for power supply. Most of these systems are used in field environments such as fields and forests. If the solar panel The charging efficiency is relatively low when installed in a greenhouse, and for wireless measurement and control nodes with control functions, the wireless radio frequency module is always in the monitoring state and consumes a lot of power. If there are continuous cloudy days, the wireless measurement and control nodes may be powered off and stop working
