USB接口信息电话机的数据采集与处理

Data sampling and processing of the Caller-ID telephone with USB Interface

用摩托罗拉公司的FSK解码芯片MC14LC5447完成对来电显示数据的解码,用AT89C2051单片机系统进行数据采集处理和数据存储,通过DLL动态链接库控制USB203(8位并行输入USB传输模块),完成对存储数据的传输,并对采集的数据进行分析处理。使用改进后的软件接口进行数据传输,实现了可用于VC、VB和DELPHI语言编程环境的接口函数。

The electronic equipment used is based on the Call - ID technology. The data of the Call - ID carried on by the telephone circuit is decoded by the FSK decoding chip of Motorola. Then, data are collected and stored by using the AT89C2051 MCU, data transmission by the modularized USB device which is controlled by the DLL interface function. Moreover, it uses the interface function to separate the data from the Caller - ID package. The equipment has the functions of collection, analysis and management of the CID data which use the interface function to transmit the data. Therefore, the interface function can also be edited by such as programming languages VC, VB or Delphi.
