【摘要】：對于當(dāng)前商場、火車站等大型空間的VAV中央空調(diào)末端裝置普遍采用有線、單點(diǎn)的采集方式,不能準(zhǔn)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(wǎng)絡(luò),采用模糊PID控制策略,設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)可無線、多點(diǎn)采集溫濕度的中央空調(diào)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(wǎng)絡(luò),實(shí)時(shí)對空調(diào)房間內(nèi)多點(diǎn)溫濕度進(jìn)行無線采集,并采用模糊推理方法,在線校正PID參數(shù),解決了大空間結(jié)構(gòu)的溫度難以準(zhǔn)確測量及所具有非線性、不確定性和時(shí)變性的控制問題。實(shí)驗(yàn)結(jié)果表明,該末端控制器數(shù)據(jù)采集準(zhǔn)確,對控制系統(tǒng)多種復(fù)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.
