Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for processing a train fault, as shown in fig. 1, including:
s101, judging whether the train has a fault.
Specifically, the train can be preliminarily diagnosed in real time according to the self network diagnosis logic of the train, and whether the current train has a fault or not is judged.
In the implementation process of this embodiment, if it is determined that the train has a fault, step S102 is executed.
Optionally, in another embodiment of the present invention, as shown in fig. 2, an implementation manner of step S101 includes:
s201, train information of the train is obtained.
Wherein, the train information includes: status information and parameter information. The state information can be whether the train can be started or stopped at present, whether the train door can be started normally, and the like; the parameter information may be current instrument information of the train, data information of devices on the train, etc.
S202, judging whether the train information of the train is consistent with the preset train information.
The preset train information may be standard train information of a train where the train leaves a factory and is provided by itself, or preset train information which is subsequently set according to actual conditions by an expert group.
Specifically, if the train information of the train is determined to be inconsistent with the preset train information, it is determined that the train has a fault.
Taking the example that the train left side door cannot be opened, in the actual operation process, after a driver presses a 'open left door' button, after waiting for 10s after giving a 'open left door' instruction to the train, the speed of the train is detected to be 0 at the same time, and the train automatic control system (automatic train control, ATC) allows the door to be opened, but at the moment, the train left side door cannot be opened, which indicates that the train left side door at the moment breaks down. The ATC uploads the situation to an internal system of the train after entering the network description logic, for example, after the train receives a train left door opening instruction, a pulse signal lasting for 3s (which can be directly interrupted by a left door closing instruction) is triggered after the train delays for 6s, and in the effective period of the pulse signal, when the train is static and the train does not receive the left door closing instruction, no left side vehicle door feedback door is in an open state, and the state continuously exceeds 1 s.
S102, acquiring fault information of the fault.
Specifically, specific information that the current train has a fault is obtained, such as that a left side door of the train cannot be opened, the train cannot be started, and the like. Simultaneously can also number the trouble that the train appears, the serial number that the left side door of train can't be opened is 20000 etc..
And S103, matching to obtain a fault tree corresponding to the fault information.
The fault tree is a logic causal graph of an inverted tree corresponding to the fault. Taking a train emergency brake failure as an example, as shown in fig. 3, a train emergency brake failure tree is shown.
It should be noted that the fault tree is a large database formed by establishing different fault trees for different faults in the emergency manual of the subway operation company.
In the specific implementation process of this embodiment, matching may be performed according to information such as a name and a number in the fault information, and a fault tree corresponding to the fault information is obtained in the fault tree group.
Optionally, in another embodiment of the present invention, one implementation manner of step S103 includes:
and matching in a fault tree group according to the state information in the fault information to obtain a fault tree corresponding to the fault information.
In a specific implementation process of this embodiment, matching may be performed according to information such as a name and a number in the state information, and a fault tree corresponding to the fault information is obtained in the fault tree group.
And S104, generating a solution strategy corresponding to the fault according to the pre-stored train emergency manual data and the data in the fault tree, and displaying a fault processing page included in the solution strategy to a driver.
The fault processing page is used for guiding a driver to process faults. Taking the failure that the right full-row door cannot be opened as an example, as shown in fig. 4, the failure processing page is a failure processing page for "the right full-row door cannot be opened". According to the name and the fault code of the fault, the fault code is the fault number in the embodiment, the fault grade can be judged once, and the time of the fault occurrence is recorded so as to facilitate the subsequent operation process; the solution strategy for processing the faults is divided into a plurality of steps, for example, the solution strategy of 'the right side all-train door cannot be opened' is 7 steps, the first step is 'pressing a' right door closing 'button of the train, using a' enabling bypass 'of the right side train door, and pressing the' right door opening 'button of the train again to try to open the door'. Each step can be divided into a plurality of small steps, for example, the steps are divided into step 1, and a button for closing the right door of the train is pressed; step 2, using a right side vehicle door 'enable bypass'; and step 3, pressing the button of opening the right door of the train again. And after the driver needs to press a 'next step' button after each step of operation, the system further prompts the operation method.
Optionally, in another embodiment of the present invention, as shown in fig. 5, an implementation manner of step S104 includes:
s501, obtaining the specific reason of the fault according to the current state information of the train, the current parameter information of the train and the fault tree in the fault information.
In the specific implementation process of this embodiment, the specific cause of the fault is found in the pre-stored fault tree according to the current state information of the train and the current parameter information of the train. As shown in fig. 3, when it is determined that the train fault is "emergency braking", the train fault is determined for the first time according to the current state information of the train, and a first determination result is obtained, as shown in fig. 4 as S2 — the train has a direction of 0; e3_ abnormal emergency braking equals 1. And further judging according to the current parameter information of the train to obtain a second judgment result, such as E31, E32, E33 and the like in fig. 3. It should be noted that the second determination result may be further determined according to a related variable, where the related variable may be a main air duct pressure of the train, a current speed limit of the train, a current speed of the train, all brake release states, a single brake release state, and the like.
And S502, combining the pre-stored train emergency manual data and the specific reasons of the fault, and generating a solution strategy corresponding to the fault information.
In the specific implementation process of this embodiment, the solution strategy corresponding to the fault information may be generated by querying in the pre-stored train emergency manual data according to the specific cause of the fault.
And S503, displaying a fault processing page included in the solution strategy to the driver.
Optionally, in another embodiment of the present invention, as shown in fig. 6, the method further includes:
s601, acquiring processing information of a driver for processing the fault.
The processing information comprises operation information of a driver in the fault processing process and a solution strategy corresponding to the fault information.
It should be noted that, after the driver processes the fault, the state information of the train and the parameter information of the train may also be obtained, so as to compare the state information of the train and the parameter information of the train when the train fails, further analyze the cause of the failure of the train, and reduce the deviation of the system when analyzing the fault.
And S602, sending the processing information to a server.
It should be noted that, when the driver processes the operation information during the fault, the processing information is sent to the server every time the driver performs one step. So that the technical personnel on the ground can monitor the relevant operation behaviors of the driver in real time, and the fault deepening of the train caused by the misoperation of the driver is avoided. And if the fault of the train still cannot be solved after the driver processes the fault according to the fault processing page, the expert can more conveniently and more accurately remotely guide the driver to repair the fault of the train through the historical experience of the expert.
In a specific implementation process of this embodiment, the operation interface in the ground system may be as shown in fig. 7A and 7B, and may include: the method comprises the following steps of basic information of a fault of the train, reference handling steps, driver station button signals, feedback records, handled steps and the like. Technical personnel, experts and the like on the ground can detect the operation behavior of a driver and the state information of the train in real time, when the driver cannot process faults, the technical personnel, the experts and the like on the ground make decisions quickly, and negative influences brought by the fault of the train are further reduced.
