Third rail heater control system
A system for remotely controlling third rail ribbon heaters is provided for preventing the accumulation of ice and snow on the rails. The system includes a plurality of switching assemblies that control a flow of electric current from the third rail of a railway to ribbon heaters mounted on the third rail. A remotely located digital controller provides switching commands to the switching assemblies via a radio link. The switching assemblies include current and voltage sensors that continuously provide current and voltage information that allows the digital controller to accurately predict when a heater failure condition is likely to occur so that ribbon heaters may be preemptively and safely replaced before failure. Each of the switching assemblies is contained in a junction box that includes both a door panel and a safety switch that disconnects the switching assembly from third rail current when the door panel is opened for improved safety.
Station building power supply device and charged-state detection method
A station building power supply device includes a circuit breaker to disconnect a connection with a train side, a circuit breaker to disconnect a connection with the station load side, a power converter disposed between the circuit breaker and the circuit breaker to convert the regenerative power into the AC power, a housing that houses the circuit breaker, the power converter, and the circuit breaker, a voltage sensor that detects a charged state of the housing, and a control unit that controls operations of the circuit breaker, of the power converter, and of the circuit breaker based on a detection result from the voltage sensor.
Method for Transmitting Traction Power Network Data
The present invention provides a method for transmitting the electric power data of a rail includes collecting electrical current analog signals from a conductor rail and transmitting the electrical current analog signals to a processing module; converting the electrical current analog signals into electrical current digital signals through the processing module; transmitting the electrical current digital signals to a monitoring platform through a wireless communication module. The electrical current information of the conductor rail is collected by an electric current sensor installed on a cable, which is connected to the conductor rail. The electrical current information collected by the electric current sensor is transmitted to the processing module after pre-processing comprising signal amplification and filtering. The present method effectively prevents problems of high bit error rates and faults with a negative impact on the data transmission with data message corrupted by noise during transmission.

CONTROL METHOD AND SYSTEM OF NEUTRAL SECTION PASSING OF MULTI-LOCOMOTIVE SHORT BROKE TRAINS
A control method and system of neutral section passing of multi-locomotive short broke trains. Distance traveled by a train after a primary multiple unit enters a neutral section is calculated in real time, so that a neutral section passing procedure of a secondary multiple unit is effectively controlled, thereby solving the problem that when the multi-locomotive short broke trains operate with double-raised pantographs, if the distance between the two pantographs is shorter than the length of a neutral zone of a neutral section and longer than the length of a no-electricity zone of the neutral section, when the two pantographs pass through the neutral sections, the two pantographs will span the two neutral sections and generate an interphase short circuit. The method improves safety of the EMU when it passing neutral section and ensure that the EMU can reliably pass through the neutral section with double-raised pantographs. The present invention has the advantages of being safe, reliable, easy to implement and convenient to promote and apply.
