随着我国禽类养殖产业化发展，禽类养殖业对养殖环境要求不断提高。在禽舍环境控制中，由于温湿度之间的耦合关系，难以同时到达设定值。所以进行禽类环境控制器的研究，实时检测温湿度，以便满足禽类的生长环境。 针对此设计了一种基于模糊PID解耦算法的多功能禽舍环境控制器，主要是环境控制器系统硬件的设计与相关软件设计，具体包括控制器的各个功能模块设计和控制算法的设计。主控IC选用DSP作为处理器，计算更加精确，支持复杂的算法运算。显示采用3.2寸带SD卡扩展的触摸屏，使得操作界面更加人性化。利用无线通讯模块将数据发送给远程终端，实现远程监控的功能。系统还有上位机用于实时在线收集数据，便于统计与计算。基于手持端短信平台，更加方便了禽舍实时监控。数据采集模块与继电器组控制模块初始化，继电器组控制模块不仅控制18路常规输出，还控制温湿度的采集，对该部分的初始化至关重要。首先关闭所有输入输出，待AD采集模块及自整定模糊PID解耦控制算法初始化完毕后，开通温湿度采集通道，得到处理结果，进而控制18路的输出。建立了新式禽舍结构模型，根据禽类日龄与温湿度，通风量以及光照的关系，采用自整定模糊PID解耦控制算法，通过模糊控制算法将实时测量的数据处理得到PID调节参数，再利用单位阵解耦原理使得温湿度控制解耦。经试验和仿真证明该系统响应迅速，灵敏度高，稳定性好。

With the development of poultry aquaculture industrialization, poultry breeding environment need to be improved. To the control of birdhouse environment parameter, the coupling relationship between temperature and humidity makes it difficult to reach the set value at the same time. So it is necessary to do the poultry environment controller research, detect real-time temperature and humidity, to meet the growth of poultry environment. In this paper we will design a multi-function birdhouse environmental control system based on fuzzy PID decoupling algorithm, mainly do the environment controller system hardware design and relevant software design, including design of each function module and control algorithm. We choose DSP as Master IC, which calculates more accurate, support complex operation. 3.2 inch touch-screen with SD card extension makes the interface more humane. Wireless communication module sends the data to a remote terminal, which can realize the function of remote monitor. WINCC is used to real-time online data collection, easy to statistics and computation. Mobile phone client software application based on the android, bring more convenience for real-time birdhouses monitoring. Data acquisition module and relay control module initialize, relay control module controls 18 normal outputs, and acquisition of control temperature and humidity, which is crucial to the initialization. First close all the inputs and outputs, after the initialization of AD collection module and self-tuning fuzzy PID decoupling control algorithm, the open the temperature and humidity acquisition channel, get the processing results to control the18 outputs. Establish new birdhouse structure model, according to the poultry day-age and temperature and humidity, ventilation rate and light, use self-tuning fuzzy PID decoupling control algorithm. With the fuzzy control algorithm get real-time measurement data to get the PID adjust parameters, unit matrix decoupling principle makes the temperature and humidity control decouple. By the experiment and simulation, it shows that the system response is rapid, high sensitive good stable.
