摘　　要：探讨了一种较为典型的红外遥控系统的设计思路,介绍了由PT2248作为发送器,MIM-R1AA38KHZ红外一体化接收解调器作为接收器的红外遥控系统的构建方法,并着重介绍了基于EDA技术的CPLD解码器的设计思想。在设计过程中,运用了当前EDA技术领域自顶向下的设计方法。系统原理简单,可靠性好,能够及时发现误码,防止误操作的产生。可应用于一般控制场合。Method for designing a typical infrared system is proposed. After introducing the general principles of transmitting and receiving, discussion on the design of an infrared remote controlled system based on PT2248, MIM -R1 AA38KHZ and CPLD decoder are performed in detail in the paper. Top - down method in EDA is involved during the design, The system shows the advantages of simplicity and good applicability. It can detect the error code and the improper operation therefore would be prevented.
