Embodiment 1

[0018] According to an embodiment of the present invention, an embodiment of a method for fault diagnosis of a rail vehicle lighting system is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be implemented in a computer system such as a set of computer-executable instructions and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0019] figure 1 It is a flow chart of a method for fault diagnosis of a rail vehicle lighting system according to an embodiment of the present invention, such as figure 1 As shown, the lighting system includes: a fault detection circuit, and the method includes the following steps:

[0020] Step S102, detecting the operating state of the lighting system through the fault detection circuit.

[0021] Specifically, the aforementioned running status may include: normal running an...

Embodiment 2

[0050] According to an embodiment of the present invention, an embodiment of a system for fault diagnosis of a rail vehicle lighting system is provided, figure 2 is a schematic diagram of a system for fault diagnosis of a rail vehicle lighting system according to an embodiment of the present invention, combined with figure 2 As shown, the system includes:

[0051] The fault detection circuit 20 is used to detect the operating state of the lighting system. When it is detected that the operating state of any module in the lighting system is faulty, obtain fault data, encode the fault data, and transmit the coding result to the track Vehicle control and management systems;

[0052] The rail vehicle control and management system 22 is connected with the fault detection circuit, and is used to obtain fault data by decoding the encoding result.

[0053] It can be seen from the above that the above-mentioned system of the present application detects the operating state of the lig...

Abstract

The invention discloses a method, device and system for diagnosing faults of a rail vehicle lighting system. The lighting system comprises a fault detection circuit. The method comprises the following steps: detecting the running state of the lighting system through the fault detection circuit; acquiring fault data under a condition that the running state of an arbitrary module in the lighting system is detected to be failed; coding the fault data, and transmitting the coding result to a rail vehicle control and management system; and decoding the coding result by the rail vehicle control and management system to acquire fault data. The method, device and system can be used for solving the technical problem in the prior art of large maintenance difficulty when the light system of a rail vehicle is failed.

Description

technical field [0001] The invention relates to the field of rail vehicle control, in particular to a fault diagnosis method, device and system for a rail vehicle lighting system. Background technique [0002] At present, the lighting fixtures on rail vehicles play an important role in the transportation of vehicles and the comfort of passengers. Once the lighting fixtures break down, it is necessary for the staff to repair the broken lighting fixtures in time. However, rail vehicles usually have multiple carriages, and multiple lamps are deployed in each carriage. Therefore, during maintenance, staff need to check one by one to find out the fault point, and then replace or maintain it, which is a waste of human resources. [0003] Aiming at the problem that the lighting system of the rail vehicle in the prior art is difficult to repair when it fails, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provi...
