Problems solved by technology

The above research is still based on wired sensors and wired controllers, without reducing the large number of signal transmission lines and power lines inside the greenhouse, so it does not fundamentally solve the defects of the existing greenhouse measurement and control system
[0009] (3) In 2006, Luo Huiqian, Zhang Xin, etc. developed wireless sensors for greenhouse environment monitoring, but only initially realized a single wireless sensor detection, and did not develop a complete wireless network measurement and control system that can suit the characteristics of greenhouses
Research on exploring the common core technologies of digital agriculture, establishing a wireless sensor network greenhouse measurement and control system, and realizing wireless optimal control of greenhouse environment and crop growth has not yet been reported.

Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Figure 1 shows the wireless sensor network architecture of the entire greenhouse measurement and control system. The sensor network in each greenhouse consists of several convergence nodes (1), several sensor nodes (2), several control nodes (3) and a control station (8). Wherein the control station (8) plays the role of the sensor network task manager, and the control center (9) performs unified management and monitoring for all greenhouses. In each greenhouse, the sink node (1) is the bridge connecting the sensor node (2), the control node (3) and the control station (8), and all collected data are sent to the control station ( 8), and the control command is sent by the control station (8) to the control node (3) through the sink node (1), and the control node (3) drives the actuator (7) to perform the control task. Deploy the mobil...

Abstract

This invention relates to greenhouse variable structure self-organizing wireless sensor network and its building method, which sets up the convergence nodes during the mobile process, the sensor and control nodes within the coverage to form Star network, and then the convergence nodes connects the control site and control center in turn. It lays the plastic track and wire of toughness as Live Wire lanyard on the top of greenhouse, fixes the aggregation nodes on the lanyard with both ends of wheel connecting electricity, installs cooling fins and fans on the aggregation nodes, to dynamically collect the greenhouse surrounding parameters acquired by different sensor nodes through aggregation nodes, and then sent to the control site, and the instructions issued by the control site is sent to the control nodes through the aggregation nodes.

Description

technical field [0001] The invention relates to a wireless sensor network architecture, in particular to a variable-structure self-organizing wireless sensor network and a construction method applied to a greenhouse measurement and control system. technical background [0002] Greenhouse environment control is based on making full use of natural resources, by changing environmental factors such as temperature, humidity, light intensity, etc. to obtain the best conditions for crop growth, so as to increase crop yield, improve quality, adjust growth cycle, and improve economic benefits. Purpose. The greenhouse environment control technology in the Netherlands, Japan, the United States, Israel and other countries has been quite advanced and has reached the level of comprehensive control of multiple factors. In recent years, my country has also obtained a lot of research results in greenhouse control. [0003] Wireless sensor network integrates sensor technology, embedded comp...
