信息融合技术及其在温湿度控制中的应用

Information Fusion Technique and its Application in the Control of Temperature and Humidity

介绍了将信息融合技术和DSP(DigitalSignalProcesser)技术结合起来应用于温室的温湿度控制中。信息融合技术提高了系统获取信息的能力,利用信息融合技术对多传感器的信息进行融合,得到的信息比单一传感器的信息全面、准确,对提高系统的控制精度起到了很好的作用。利用数字信号处理器TMS320LF240DSP作为CPU实现对控制对象的控制,算法简单、运算速度快、实时性好。系统运行结果表明,该控制方法与通常对温湿度进行解耦的控制方法相比较,控制比较简单,而且控制精度得到了提高。

The technic to the controlling of the tempreture and humidity by combining the technic of information fusion and Digital Signal Processer is applied. Information Fusion inproved the system ability of capturing information. The information, obtainedby multi-sensor information fusion, is more complete and accurate than the information obtained by singl sensor. So the technic has good effect on inhencing the system controlling precision. By using TMS320LF240 DSP as CPU achieved the con-trollingcansimply thearithmetic and improve the operation speed. The system running indicated that the controllingmethod is more simple and precision than the general controlling method of discompling the tempreture and humidity.
