Abstract

The invention provides a remote greenhouse temperature control system composed of a management unit, a wireless transmission unit and a control unit. The management unit accesses the control unit through the wireless transmission unit and monitors the real-time temperature state of a greenhouse. The control unit adjusts the temperature of the greenhouse in real time through a control algorithm based on single neural element PID. The greenhouse temperature object generally fluctuates in a crop tolerable temperature range, and at the moment, a heating element is controlled to realize a temperature adjustment function; and only when the greenhouse temperature object exceeds a highest crop tolerable temperature, the temperature reducing element is controlled to carry out water spraying for temperature reduction. According to the invention, a WI-FI network is used as a transmission medium, the monitoring range is flexibly enlarged or shortened by the multi-layer distributed wireless network, the number of required greenhouse temperature monitoring nodes can be conveniently increased or reduced, and the greenhouse temperature control efficiency is simultaneously improved; in addition, a neural network calculation principle and a routine PID control algorithm are combined, the control efficiency is improved, and the system performance is optimized.

Description

technical field [0001] The invention relates to a greenhouse temperature monitoring system, in particular to a greenhouse temperature monitoring system based on a WI-FI wireless data transmission method and a single neuron PID control algorithm. Background technique [0002] With the development of my country's national economy, people's living standards are improving day by day, and the market for greenhouse vegetables in winter is expanding day by day, especially in northern regions where vegetables are cultivated in plastic greenhouses in cold winter, which reflects economic value. Greenhouse temperature control, that is, according to the needs of crop growth and development, through sensor technology, microcomputer, single-chip microcomputer technology and artificial intelligence technology to realize the automatic adjustment of greenhouse temperature, so that crops can obtain better than outdoor growth in off-seasons that are not suitable for growth and development. env...
