基于单片机和无线数传电台的流速仪信号器的研制

传统水文缆道使用"有线"或"无线"回路进行流速信号传输,但是这两种回路都存在结构复杂、电参数不稳定等固有缺点,所以造成传输不稳定、故障排查困难等问题,严重影响了测流工作的正常进行。本文提出采用单片机作为控制核心,使用无线数传电台建立传输信道来进行流速信号传输,经过实用取得了较好效果。

Development of Current Meter Annunciator Based on SCM and Wireless Data Radio

The traditional hydrological cableway use "wired" or "wireless" loop to transport the signal of current meter, but these two loops has the inherent disadvantages such as complicated structure, unstable electricity parameter, so the transmission is not stable and the troubleshooting is difficult, which has seriously affected the work of discharge measurement. This paper presented single chip microcomputer as control core and wireless data radio as channel to transport the signal of current meter, which has obtained the good effect in practice.
