水文缆道信号传输的研究

Study on Signal－transmission of Hydrological Cableway

利用缆道回路传递流速、水面、河底、采样等多信号问题，至今尚未彻底解决，严重影响了我国水文缆道测验技术的发展。根据近期研制的全自动水文缆道测流系统和近20多年的缆道测验实践，提出了缆道的交流等效概念和多信号的产生与传输以及实施方案。

： The problem of multi－signal transmission by cableway loop has not been solved yet． It seriously affects the development of hydrological cableway technology in China． Based on the recent research practice of hydrological cableway automation system for velocity and current measurement， as well as the experience of around 20 years work in the field， the author brought forward the concepts of alternating equivalent circuit． The production and transmission of multi－signal has been analyzed， an implementation plan using cableway to transmit multi－signal has been presented．
