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...
