| Greenhouse is of great significance to the cultivation of Inverse-seasonal vegetable in the north.Research found that many agricultural greenhouses concentrated in the northern city of Shijiazhuang Gaocheng area.But it's regulation and control capability?management style and production efficiency needs much improved.In order to solve this question,the paper presents a program based on STM32 single-chip intelligent greenhouse control system.Which environment parameter can be automatic detection and control,the Intelligent?automatic and scientific will achieve the aim of it's performance requirements.In the paper,it carried out a detailed analysis to the habitat of plant,On this basis a In the paper,it carried out a detailed analysis to the habitat of plant,On this basis a scheme is presented for choosing the processor?sensor and communicating module.scheme is presented for choosing the processor?sensor and communicating module.From the practical point of view of the project,Select the highly integrated type of sensor,it can output standard analogue signal,the method of fabric distribution is analyzed.The system hardware and some interrelated circuits has been designed.In terms of what the parameters of environmental wants process,different types of data using different processing options,Regulation of timing is in a reasonable arrangement,based on these tasks the software programming have a clear thread.The greenhouse is a non-linear and large dead-time processes,there will be a discussion about the fuzzy control applied in green house in the paper.The Database-Monitor-StatsPack browser is simple and friendly will meet the demand of distributed control.The system was tested in the simulation environment,these tests have been proved reasonable of hardware system and communication networks.It has favorable effect in the paper about the methods of environmental parameter,the Pre-project basically meet the intelligent greenhouse design requirements. |
