【摘要】：对于当前商场、火车站等大型空间的VAV中央空调末端装置普遍采用有线、单点的采集方式,不能准确表征整体空间环境特征,并且末端控制器控制效果较差的问题。基于ARM9和无线传感器网络,采用模糊PID控制策略,设计并实现了一个可无线、多点采集温湿度的中央空调末端智能控制器。其借助TinyOS操作系统组建无线传感器采集网络,实时对空调房间内多点温湿度进行无线采集,并采用模糊推理方法,在线校正PID参数,解决了大空间结构的温度难以准确测量及所具有非线性、不确定性和时变性的控制问题。实验结果表明,该末端控制器数据采集准确,对控制系统多种复杂特性均具有良好的控制效果。
[Abstract]:For the current VAV central air conditioning terminal devices in large space, such as shopping malls and railway stations, cable and single point acquisition methods are generally used, which cannot accurately represent the overall spatial environment characteristics. Based on ARM9 and wireless sensor network, a wireless controller is designed and implemented with fuzzy PID control strategy. The intelligent controller of central air conditioning terminal based on multi-point temperature and humidity collection, with the help of TinyOS operating system, is used to set up a wireless sensor collection network, to collect air conditioning room temperature and humidity wireless in real time, and to adopt fuzzy reasoning method. By on-line correcting PID parameters, the temperature of large space structure is difficult to be measured accurately and the nonlinear, uncertain and time-varying control problems are solved. The experimental results show that the end controller is accurate in data acquisition. It has good control effect on many complex characteristics of control system.
