Intelligent agricultural greenhouse monitoring and controlling system based on wireless passive technology

Abstract

The invention discloses an intelligent agricultural greenhouse monitoring and controlling system based on a wireless passive technology. The system comprises a control terminal, a master control machine room and a plurality of greenhouses, a remote control network is formed by the control terminal and the master control machine room through the internet, an inter-greenhouse ad-hoc network is formed by the master machine room and the greenhouses through a net-shaped ZigBee ad-hoc network, a single-greenhouse central control module, an execution module and a wireless passive ZigBee sensing module are arranged in each greenhouse, and a single-greenhouse sensing control network is formed by the single-greenhouse central control module, the execution module and the wireless passive ZigBee sensing module in the single greenhouse through a star-shaped ZigBee ad-hoc network. The wireless passive sensing modules based on the EnOcean wireless communication standards are adopted by wireless sensing equipment, and a ZigBee wireless networking technology is matched to achieve a passive wireless ad-hoc network so that the problem of energy supply of the greenhouses under the condition of no wire arrangement or little wire arrangement can be solved.

AI Technical Summary

Problems solved by technology

[0012] The existing greenhouse adopts ZigBee wireless networking technology, which solves the problem of wireless transmission of monitoring and control data. The energy-consuming components in a single greenhouse are powered by solar energy. However, due to the large number of wireless sensing devices, if all of them use solar power , a large amount of wiring is required in the greenhouse, which is relatively complicated. If a single battery without wiring is used, it is not easy to replace and maintain. Therefore, how to solve the problem of energy supply in the greenhouse under the condition of no wiring or less wiring is an urgent need. Important research topics addressed
