红外接收器的设计研究
摘要：随着科学技术的发展，单片机因其该可靠性和高性价比，在智能化家用电器仪表仪器等恒多领域得到极为广泛的应用。在很多实际单片机系统中，常常使用非电信号，如光信号，超声波信号等，来传播信息，以实现遥控和遥测的功能，其中红外遥控是目前最广泛的一种通信和控制手段。
由于红外线遥控装置具有体积小、功耗低、功能强、成本低,抗干扰强等特点，因而，继彩电、录像机之后，在录音机、音响备、空凋机以及玩具等其它小型电器装置上也纷纷采用红外线遥控。
本课题掌握52系列单片机和红外技术为目的，以红外线为信息传输载体，对受控对象进行短距离无线控制。

The Design And Research of Infrared Receiver
Abstract：With the development of science and technology， SCM because of its high reliablityand cost-effective,in the home appliaances,instrumentation and many otner areas has been widely a lot of practical single-chip microcomputer systemys, non-electrical signal is widely used to comumicate information, and to achieve the function of remote control and remote sensing, including infrared remote control is the most extensive a communication and control ways.
As the infrared remote control device with small size, low power consumption, stronger function and lower costs, the tape recorder, audio equipment, air conditioning machines and other small electric equipment toys take use of infrared remoe control one after another following TVS, VCRS.
For the purpose of mastering MCS-52 and infrared technology,this topic treats the infrared as information carrier, controls objects in wireless short-range.
