Wireless sensor network-based greenhouse temperature control system

Abstract

The invention discloses a wireless sensor network-based greenhouse temperature control system which includes a video data acquisition module, a sensor module composed of a plurality of monitoring nodes internally provided with Beidou modules, an outdoor environment acquisition module, a central processor, an environmental control module in a greenhouse and a three-dimensional simulation module. Through the arrangement of the sensor monitoring nodes with the Beidou modules, the temperature, humidity, and carbon dioxide concentration in the greenhouse are detected, and control commands of the environmental control module in the greenhouse are output according to detected data through the central processor, so that the environment in the greenhouse is automatically controlled; panoramic videocapture is adopted for video capture, to improve the coverage of video monitoring, and real-time monitoring of the situation in the greenhouse is achieved; through the design of the three-dimensionalsimulation module, the three-dimensional delivery of greenhouse conditions is achieved, monitoring workers can observe the conditions in the greenhouse personally on the scene, and thus various reasonable environmental control schemes can be formulated conveniently.

Description

technical field [0001] The invention relates to a temperature control system, in particular to a temperature control system in a greenhouse based on a wireless sensor network. Background technique [0002] Greenhouses, also known as greenhouses, can transmit light, keep warm and heat, and are mostly used to cultivate crops. For greenhouses, the most important management factor is temperature control. If the temperature is too low, vegetables will freeze to death or stop growing. If the temperature is too high It is also not conducive to the growth of vegetables, so in the process of vegetable cultivation, the temperature of the greenhouse must always be controlled within the range suitable for vegetable growth. However, at present, the temperature control of greenhouses mainly relies on manual control. This method of temperature control not only consumes a lot of manpower, but also is prone to errors. A little carelessness will cause irreparable damage to the planted crops a...
