Research on Carrier Communication Technology by Railway Train Catenary in Industrial and Mining Enterprises

The frequency shift track circuit is usually used to transmit the information needed by the normal operation of electric locomotive. Frequency shift track circuit requires more equipment, and its parameter debugging is more troublesome.In addition, the workload of the frequency shift track circuit is large, and it is not easy to find fault when the equipment fails. The railway train catenary carrier technology can simplify the equipment needed for the communication of electric locomotive.The utility model has the advantages of small volume, easy to find fault, and low cost.
