单片机无线数据传输接口C程序设计

介绍一种抗干扰能力强的单片机无线数据传输接口的工作原理与软件设计。主控芯片采用AT89C51单片机,信方式采用抗干扰能力强、可靠性高的DTMF信号和单工调频的无线通信方式。十六DTMF信号码作为信息帧的十种位码,以及采用校验码进行检错和纠错,数据传输误码率几乎降到为零,极大地提高了无线数据传输质量。软件采C51模块化设计,可方便地进行移植以实现各种数据的区域无线传输。本接口可应用于实验室大型仪器设备的无线通自动登记和管理系统,也可应用于无线通信动抄表系统等。

-Single-chip wireless data transmission interface C Programming

A strong anti-interference ability of the single-chip wireless data transmission interface and software design principle. AT89C51 single-chip microcomputer control chip, the letter means the use of anti-interference ability, high reliability and the DTMF signal and FM simplex radio communication. Letter No. 16 as the DTMF information of the ten-bit code frame, as well as the use of checksum error code and error correction, so that data transmission error rate dropped to almost zero, has greatly improved the quality of wireless data transmission. C51 mining modular software design, can be easily transplanted to the region to achieve a variety of wireless data transmission. The interface can be applied to large-scale laboratory equipment wireless Automatic registration and management system, also can be applied to wireless communications, such as automatic meter reading system.
