摘要
当前较常见的是单独借用某一种线路进行数字信号传输 ,而利用单片机技术综合运用多介质进行数据传输尚不多见。本文结合运用于某仓库系统的安全环境智能测控系统 ,就数字信号在电力线和普通电话线中的传输技术进行了探讨。最后介绍了衰减模型的建立和实验。
It is common to utilize some line in digital signal transmission but less common to utilize single chip computer technology and multimedia comprehensively in data transmission. This article, based on the safety environment intelligent test and control system applied in our storehouse,introduces the application of the single chip computer in data communication by power lines and common phone lines. With the experimental data of digital signals transmitted in different medium.
