摘要
针对矿用带式输送机综合保护系统供电和通信距离长、线缆成本高的情况,将低压直流载波通信技术引入系统应用,可有效减少供电和通信电缆芯数,降低系统成本。低压直流载波通信技术采用满幅电压发送、电流信号回传的方式,提高了通信的抗干扰能力。
Based on comprehensive protection system of belt conveyor for mine with long power supply and communication distance and high cable cost,low voltage DC carrier communication technology was introduced to the system to reduce number of power supply and communication cable cores and system cost.Low voltage DC carrier communication technology adopted full voltage transmission,current signal back transmission to improve anti-interference capability of communication.
