摘要

为进行多领域空调系统的整体性能分析,基于Modelica建立了串口通信模型和空调模型,利用自编程的信号调理电路和已建立的串口通信模型将空调模型与空调控制器进行连接,建立了空调半实物仿真系统,仿真实验结果证明了本系统的有效性.本空调半实物仿真系统为多领域系统的半实物仿真提供了一套新的解决方案,可有效提高产品研发效率,降低研发成本.%To analyze the whole performance of the air-conditioning system containing different domains, the models of serial port communication and air-conditioning are established based on the multi-domain unified modeling language Modelica, the air-conditioning hardware in the loop(HIL) simulation system is created by connecting and air-conditioning controller and model with the serial port communication model and the signal process circuitry, and the result of simulation shows the effectiveness of the system. The HIL simulation system of air-conditioning provides a new method of HIL simulation for multi-domain systems, which improves the efficiency of production design and reduces the cost evident-ly.
