Strawberry greenhouse wireless monitoring and control system based on adaptive control

Abstract

The invention relates to the technical field of crop planting and particularly relates to a strawberry greenhouse wireless monitoring and control system based on adaptive control. Multi-link precise control over a strawberry growing environment in a greenhouse can be realized. The system comprises sensors, a cloud platform and an upper computer. A plurality of sensors are set. Sensor data is forwarded to the cloud platform through utilization of a bus network. Cloud platform data is synchronized with the upper computer. The upper computer stores a control method and preset parameters. The system also comprises an adjustment device. The adjustment device is controlled by the upper computer. The control method comprises adaptive Smith estimation control, adaptive internal model control and simple switching quantity control. The sensors uploads data measured in a greenhouse to the cloud platform, the upper computer adjusts the environment of the greenhouse through comparison of the presetparameters and the measured data, and in three different modes of the adaptive Smith estimation control, the adaptive internal model control and the simple switching quantity control, different parameters can be adjusted.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a wireless monitoring and control system for strawberry greenhouses based on adaptive control. Background technique [0002] my country is one of the earliest countries to use agricultural greenhouses. As early as 2000 years ago, various protective measures have been used to protect the growth of crops. This can be regarded as the earliest agricultural greenhouses. Until the 1960s, my country’s agricultural facilities have been in a Low level, extremely slow developing condition. In the 1970s, plastic film mulching technology was introduced to China, which played a certain role in keeping crops warm. In the 1980s, solar greenhouses and plastic greenhouses appeared in China. Since the 1990s, my country’s agricultural greenhouse technology has been significantly improved, and national scientific research projects have been launched one after another. On the basis of continuou...

Problems solved by technology

[0005] China's greenhouse construction, whether in terms of greenhouse facilities or cultivation management, is mostly simple in structure, with very limited adjustment and control of the environment, and mostly based on traditional experience, which is far from the requirements of quantification and indexization. The large gap and the lack of theory on the control system also lead to high equipment operating costs
