Telephone system of locomotive under coupled running mode

Abstract

The invention provides a telephone system for locomotives under a coupled running mode, comprising telephones and coupled running telephone lines, wherein the telephones are arranged in all the locomotives; the coupled running telephone lines are connected with the telephones in all the locomotives; each telephone comprises a phone body, a microphone, four telephone interfaces and a telephone circuit; the telephone circuit comprises a phone power circuit, a ringing triggering circuit, a ringing circuit and a speaking circuit; the phone power circuit comprises a power port light-emitting diode, a filtering circuit and a phone power output end; the filtering circuit consists of an inductor and a capacitor; the ringing triggering circuit mainly comprises an NE555 integration module, a transformer, a switch relay and a plurality of capacitors and resistors; the speaking circuit mainly comprises a speaking chip TEA1062, an inductor, a voltage-stabilizing diode and a plurality of capacitors and resistors; the phone body is provided with an embedding groove; and the microphone and the embedding groove are provided with magnets with high and strong magnetism. According to the telephone system, the operation is simple and convenient, the performance is reliable and the smoothness for communication among drivers and passengers of the locomotives under the coupled running mode can be ensured.

Description

technical field [0001] The invention relates to a communication device between locomotives in a double-connected operation mode, in particular to a telephone system for communication between locomotive drivers and passengers in a double-connected operation mode. Background technique [0002] With the continuous development of railway transportation, in the operation of main railway lines, one locomotive traction for each train sometimes cannot meet the transportation requirements, and multiple locomotive traction is required. Using multiple locomotive traction can greatly increase the passing capacity of the line and improve Economic indicators of rail transport. When multi-machine traction is used for trains on the main line, several drivers can operate one locomotive and each locomotive cooperates with each other, or the electrical lines of each locomotive can be connected to each other through the multi-core cable plugs at both ends of the locomotive. A driver operat...

AI Technical Summary

Problems solved by technology

However, if a locomotive trips due to a fault during operation, in order to restore the locomotive after the fault is eliminated, sometimes the other locomotive must be de-energized to the initial state of starting to restore the faulty locomotive, thus making all locomotives lost traction

Therefore, locomotives with low-quality locomotive parts and unreliable work are not suitable for heavy-duty operation
