【摘要】：對于當前商場、火車站等大型空間的VAV中央空調末端裝置普遍采用有線、單點的采集方式,不能準確表征整體空間環(huán)境特征,并且末端控制器控制效果較差的問題�；贏RM9和無線傳感器網絡,采用模糊PID控制策略,設計并實現(xiàn)了一個可無線、多點采集溫濕度的中央空調末端智能控制器。其借助TinyOS操作系統(tǒng)組建無線傳感器采集網絡,實時對空調房間內多點溫濕度進行無線采集,并采用模糊推理方法,在線校正PID參數,解決了大空間結構的溫度難以準確測量及所具有非線性、不確定性和時變性的控制問題。實驗結果表明,該末端控制器數據采集準確,對控制系統(tǒng)多種復雜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.
