wtb contact deoxidation circuit

Abstract

The invention provides a WTB contact deoxidation circuit. The circuit comprises an isolation power supply, a filter circuit, a relay switch circuit and a processor interface circuit connected in sequence, wherein the isolation power supply is used for providing a power-up clear power supply; the filter circuit is used for filtering the power-up clear power supply; the relay switch circuit is used for applying the filtered power-up clear power supply to a WTB contact according to control signals, and sending a power-up clear action feedback signal to the processor interface circuit; the processor interface circuit is used for outputting the control signals to the relay switch circuit; and the control signal comprises the power-up clear action signal and the power-up clear action feedback signal. According to the WTB contact deoxidation circuit, the oxidation problem of the WTB contact is solved, and the reliability of WTB communization is improved.

Description

Technical field [0001] The invention relates to a vehicle control technology, in particular to a wire train bus (Wire Train Bus, WTB) contact deoxidation circuit. Background technique [0002] WTB is a communication bus widely used in trains and vehicles that require dynamic marshalling. It can automatically marshal vehicles after the configuration of the trains and vehicles changes to form a new vehicle topology. WTB bus contacts are usually on the outside of the train. Due to the weather, the contacts are prone to oxidation, leading to poor contact and affecting bus communication. Summary of the invention [0003] The present invention provides a WTB contact deoxidation circuit to solve the problem of WTB contact oxidation and improve the reliability of WTB communication. [0004] The present invention provides a WTB contact deoxidation circuit, comprising: an isolated power supply, a filter circuit, a relay switch circuit and a processor interface circuit connected in sequence; ...

AI Technical Summary

Problems solved by technology

WTB bus contacts are usually on the outside of the train. Due to the climate, contact oxidation is prone to occur, resulting in poor contact and affecting bus communication.
