Embodiment 1

[0059] This embodiment provides a method for fault diagnosis of train display screens, which can be used for fault diagnosis of display screens in a train network control system. The method can be executed by a fault diagnosis device, and can be implemented in the form of software and / or hardware. The fault diagnosis device can be arranged in a computer, and the computer is connected with the train display screen.

[0060] figure 1 It is a flow chart of the fault diagnosis method for the train display screen provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the fault diagnosis method of the train display screen provided by the present embodiment includes the following steps:

[0061] Step 101. The fault diagnosis device creates fault data according to the preset fault signal list. The fault data includes at least one fault, and each fault corresponds to a fault trigger parameter. The fault trigger parameters include: fault activation mode, and the...

Embodiment 2

[0077] This embodiment further improves the fault diagnosis method of the train display screen on the basis of the above embodiments.

[0078] figure 2 It is a flow chart of the fault diagnosis method for the train display screen provided by Embodiment 2 of the present invention. Such as figure 2 As shown, on the basis of the above steps 101 to 104, the fault diagnosis method of the display screen also includes the following steps:

[0079] Step 105, the fault diagnosis device receives a fault setting signal input by the user.

[0080] In addition to the above-mentioned OPC server being able to send a fault signal list to the fault diagnosis device, the user can also directly input a fault setting signal to the fault diagnosis device, that is, operate on the control interface provided by the fault diagnosis device to provide a fault diagnosis device. Fault set signal. The fault setting signal is used to directly set one or several faults.

[0081] Step 106, the fault di...

Embodiment 3

[0092] This embodiment further improves the fault diagnosis method of the train display screen on the basis of the above embodiments.

[0093] The above-mentioned fault triggering parameters also include: a fault clearing mode, and the fault clearing mode is simultaneous clearing or interval clearing.

[0094] The fault diagnosis device sets the fault clearing method for each fault in the fault data as simultaneous clearing or interval clearing. If it is cleared at the same time, it will clear the faults of the corresponding items at the same time; if it is cleared at intervals, it will be cleared according to the set interval time and interval order to clear the faults of the corresponding items in turn.

[0095] For example: two air-conditioning units are arranged in a carriage, which are called the first air-conditioning unit and the second air-conditioning unit. Wherein, the first air conditioner unit is provided with two compressors, which are referred to as: the first c...

Abstract

The invention provides a fault diagnosis method and device for a train display screen. The method comprises the steps that fault data is created according to a preset fault signal list; the fault datacomprises at least one fault, and each fault corresponds to fault trigger parameters; the fault trigger parameters include a fault activation mode, and the fault activation mode is cyclic activationor sequential activation; a first fault log is generated based on each fault in the fault data and the fault trigger parameters and according to first preset rules; the fault data and the fault trigger parameters are sent to a train display screen device so that the train display screen device can generate a first fault text based on the fault data and the fault trigger parameters and according tothe first preset rules; and the first fault text is compared with the first fault log, and a fault diagnosis result is generated. Through the fault diagnosis method and device for the train display screen, the efficiency of performing fault diagnosis on the display screen can be improved.

Description

technical field [0001] The invention relates to a fault diagnosis technology for a train display screen, in particular to a fault diagnosis method and device for a train display screen. Background technique [0002] The network control system of the train is to connect the signal system, traction system, braking system, auxiliary power supply system, air conditioning system, door control system, passenger information system, and fire alarm system in the train through the data bus, and through the input The output module is connected with the control circuit and the electric circuit in the train. The display screen is an important part of the network control system, which is used to display the operating data and fault data of each system. Running software is set in the display screen, which is used to analyze and process the data packets sent by the external device, and drive the display screen to display. If there is an error in the display of the fault data on the displa...
