Wireless intelligent measurement and control system of greenhouse

Abstract

The invention relates to the field of microcomputer automatic control and in particular relates to a wireless intelligent measurement and control network system of a greenhouse. The system comprises wireless sensor nodes, wireless sink nodes, wireless control nodes and an optimal control station, wherein the wireless sensor nodes are used for acquiring different environmental information and biological information and transmitting data to the wireless sink nodes in a wireless multi-hop routing manner; the wireless sink nodes are used for carrying out appropriate sensing information fusion on the data obtained from the wireless sensor nodes and transmitting sensing information to the optimal control station through a middle-long distance wireless data transmission module; the optimal control station is used for calculating an optimal control strategy based on the sensing information by utilizing a crop expert system or generating a control command according to a command of a remote user or a short-range user in combination with status of various control equipment and sending the control command to the wireless sink nodes; and the wireless sink nodes are used for forwarding the control command to the wireless control nodes so as to control an executive device, thus achieving the purpose of optimal control on the environmental information.

Description

technical field [0001] The invention relates to the field of microcomputer automatic control, in particular to a wireless intelligent measurement and control system for a greenhouse. Background technique [0002] With the rapid development of my country's agricultural modernization, agriculture is becoming more sophisticated, energy-saving, efficient and environmentally friendly, and the requirements for the environment are becoming more and more stringent. The breeding, growth, flowering, and fruiting of rare landscape plants are strictly controlled by various Due to the influence of various natural environments, precious plants have high requirements for growth environmental factors and require very fine control. However, there is a direct link between factors such as light, temperature, and moisture. For example: irrigation can increase moisture, but also reduce temperature and reduce light (water mist); shading can reduce light and reduce temperature to increase moisture...

AI Technical Summary

Problems solved by technology

Most of my country's high-end greenhouse measurement and control systems need to be imported from abroad, which are expensive and difficult to adapt to the growth patterns of cultivated crops in different regions of my country. Therefore, there is an urgent need to develop low-cost and high-efficiency wireless greenhouse measurement and control systems with independent intellectual property rights.
