摘要
在水文缆道上采用半双工的传输方式来实现多路信号传输。由于传输介质是水文缆道,因此在整个传输的过程中,存在干扰的问题。在硬件电路设计上通过抑制干扰源、切断干扰传输路径、提高敏感元件抗干扰能力等方式做到抗一定幅度的干扰:在软件设计上选用优选算法,配合硬件来提高抗干扰的能力,从而提高测量的精度和设备使用的可靠性。本文主要阐述在水文缆道上实现多路信号传输通信的原理,硬件、软件设计以及实际应用问题。
The multi-channel signal is generally transmitted at half-duplex mode on the hydrometric cableway.Since the transmission media is cableway,a problem of interference exists in transmission.In order to solve this problem,some measures can be made,such as designing to resist interference at a certain degree by controlling the interference source in circuit,cutting off transmission path of interference and improve anti-interference capability of sensors.As for the software design,optimization algorithm should be adopted in combination with the hardware to improve the anti-interference capability so that the accuracy of measurement and reliability of equipments can be improved.This paper expounded the theory of multi-channel signal transmission on the hydrometric cableway,design of the hardware and software,and some issues related to application.
