红外收发模块在家用水表中的应用

摘要

For realizing the function of getting the information of water meter system at a distance, the design of remote communications with infrared transceiver module and the hardware and software design of the system are proposed. The infrared part of the hardware uses the infrared transceiver module TFBS6614 and endec IC TOIM4232. The program is completed with the software ICC AVR. The waveform of signals can be got rightly. The system is characterized by operating simply and communicating exactly after practice. The system is suitable for the design.%为了实现远程获取水表系统中的信息，提出了使用红外收发模块远程通信的设计方案，并完成系统的软硬件设计。硬件中红外部分采用串行红外收发模块TFBS6614及其调制解调模块TOIM4232，软件采用ICCAVR编程。能够得到正确的信号波形。实际应用表明，该系统具有操作简便、通信准确的特点。达到了设计要求。
