本文介绍了寄生传输线的信道特性和信道模型，寄生传输线具有衰减大、输入阻抗
小、很强的时变性和干扰大的特点。信道模型为一线性时变系统。整个信息寄生传输系统由控制中心主机部分和监测点终端部分组成，最后说明了系统的软件设计。本文介绍的信息寄生传输系统已成功应用到仓库报警和温湿度检测中。
关键词：温湿度；时变系统； 信道模型；单片机；寄生传输
Abstract: This paper introduces the channel characteristics and the channel model for the
parasitical transmission line. The parasitical transmission line has characteristics of great
attenuation, small input resistance, time variant and big interference. The channel model is a
linear time variant system. The parasitical transmission system for information is composed of
the host computer in the control center and the terminal in the monitoring locale. Finally, the
paper describes the software design of system. The introduced system in this paper has
successfully been used in the alarm and the temperature and humidity detecting for the storage.
Keyword: temperature and humidity detecting; time variant system; channel model;
microcontroller; parasitical transmission
