Remote control circuit based on vehicle equipment power supply board card and control method thereof

Abstract

The invention provides a remote control circuit based on a vehicle equipment power supply board card and a control method thereof, and the circuit comprises a 110V input power supply module which is used for providing an input voltage for the vehicle equipment power supply board card; a remote turn-off control signal conditioning module which is used for generating a control signal to the 5V output power supply module and the 3.3 V output power supply module according to the input voltage signal transmitted by the input power supply module; a 5V output power supply module which is used for responding to the control signal and providing 5V input voltage for a rear-end vehicle equipment power supply board card; and a 3.3 V output power supply module which is used for responding to the control signal and providing 3.3 V input voltage for the rear-end vehicle equipment power supply board card. When the remote control voltage is 110 V, the remote control voltage unit is switched on, the output of the 5V output voltage unit and the output of the 3.3 V output voltage unit are switched off, and when the remote control end is suspended, the remote control voltage unit is not switched on, and the 5V output voltage unit and the 3.3 V output voltage unit output normally.

Description

Technical field[0001]The invention relates to the technical field of remote control of vehicle equipment power supply boards, and in particular, to a remote control circuit based on vehicle equipment power supply boards and a control method thereof.Background technique[0002]With the rapid development of my country's economic level, cities have vigorously developed rail transit to provide convenience for people to travel, and at the same time promote the continuous improvement of the economy. It is precisely in such a good development environment that the rail transit industry grows and grows rapidly. With the vigorous development of the rail transit industry, the good performance of on-board equipment is becoming more and more important, and the performance of the on-board equipment power system is extremely critical. In some cases where the operating environment is severe or abnormal interference is serious, the on-board equipment may appear If the performance is abnormal, even the...

Problems solved by technology

With the vigorous development of the rail transit industry, the good performance of the on-board equipment is becoming more and more important, and the performance of the power supply system of the on-board equipment is extremely critical. In the case of abnormal performance, even the soft reset of the device cannot solve the abnormal problem, which affects the normal function of the device or the stable operation of the vehicle. At this time, a hard reset of the device is required

At present, the power board generally does not have the function of remote power off or hard reset restart. When an abnormal condition of important equipment occurs and soft reset cannot be resolved, it may be necessary for the relevant staff to perform on-site operations after the train stops or returns to the warehouse. Unable to solve fault problems in real time through remote control
