本文叙述了有关架线机车载波通讯的特点,并提出了有关通讯方式的选择意见.作者认为矿井中使用单工双向载波机较为合适.本文较详细地讨论了设计这种载波机时需要考虑的一些问题,并提出一种新的单工双向载波机电路,以及这种载波机的电气性能及现场试验结果.试验证明这种载波机灵敏度较高,杂音较小,通讯距离较远,适于矿井应用.本文并提出了在不同供电方式的架线上减弱电气杂音干扰的方法.
This paper describes the characteristics of carrier communication of wired locomotives and puts forward some suggestions about the communication methods.The author thinks it is more suitable to use simplex bidirectional carriers in mines.In this paper, Some problems and put forward a new simplex bi-directional carrier circuit, as well as the electrical performance of this carrier and the field test results.Experiments show that this carrier has high sensitivity, small noise, communication distance, suitable Mine application.This paper also put forward the method of reducing the interference of electrical noise on the different power supply lines.
