摘　　要：过去的基于单片机的大棚温度控制系统,通过单片机控制温度模块、继电器模块实现对大棚内温度的检测,由于其未采用温度控制设备,造成温度控制的振荡频率大、响应速率慢的弊端。设计基于物联网的大棚温度联合智能控制系统。其基于物联网感知层、应用层和网络层的基础框架,采用分布式模块化设计方式设计系统总体架构,总体结构包括温度采集模块、网络传输模块以及远程控制模块,三个模块协同运行实现温度信号的采集、变换、存储以及监控。通过联合智能模糊PID控制器在远程控制模块中联合处理大棚内的温度信息,联合智能模糊PID控制器对系统静态误差进行实时调整减弱静态误差和振荡频率,再采用模糊PID算法调整回路输出结果,控制系统稳定性和响应速率。系统软件部分采用C5409A XDS510 Emulator仿真器对大棚室内温度控制的程序进行编写、接口控制以及编译连接等操作,共同对程序的编译进行加载,实现大棚内温度的自主控制。实验结果表明,所设系统可显著提升降低温度控制时的振荡频率和响应用时。Since the past greenhouse temperature control system based on the single chip microcomputer(SCM)realizes the indoor temperature detection of greenhouse by using the SCM to control the temperature module and relay module,large os-cillation frequency and slow response rate of temperature control are caused due to lack of temperature control equipment.There-fore,a greenhouse temperature joint intelligent control system based on Internet of Things(IoT)is designed.On the basis of the IoT foundation framework of the perception layer,application layer and network layer,the overall architecture of the system is designed by adopting the distributed modularized design pattern.The overall structure is composed of the temperature acquisition module,network transmission module and remote control module.The three modules operate coordinately to realize acquisition,transformation,storage and monitoring of temperature signals.The joint intelligent fuzzy PID controller is used to jointly process indoor temperature information of greenhouse in the remote control module,so that the static error of the system is adjusted in real time to reduce the static error and oscillation frequency.The fuzzy PID algorithm is used to adjust the output result of the loop,and control the stability and response rate of the system.For the software part of the system,the C5409A XDS510 Emula-tor is adopted to perform operations such as program compiling,interface control,and compilation connection for indoor tempera-ture control of greenhouse,so as to cooperatively upload the program compilation,and realize autonomous control of greenhouse temperature.The experimental results show that the designed system can significantly improve the oscillation frequency when the controlled temperature is decreased and shorten the system′s response time.
