Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of on-board fault emergency disposal of city regional rapid rail train, in particular to a fault emergency disposal method, device, medium and equipment of on-board navigation type pop-up screen. BACKGROUND

[0002] The city regional rapid rail line vehicle has the operation characteristics of high-speed rail and subway, and the operation mode has the characteristics of fast start and stop, rapid boarding and alighting, and large passenger capacity. It faces complex working conditions such as large load, high impact force, frequent start and stop, and wide speed range, and has the characteristics of various diseases and frequent occurrence. Therefore, sudden train failure will cause more serious impact, and the requirement of fault emergency disposal on the driver is more stringent.

[0003] In the prior art, only the fault state of the equipment of the train is diagnosed, and the fault code and processing suggestion are output according to the diagnosis result. Since the diagnosis principle is for the equipment itself, the following problems are caused:

[0004] (1) Since the output fault code and processing suggestion are inaccurate, the driver cannot effectively handle according to the processing suggestion.

[0005] (2) In addition, since the current train fault processing system only considers the fault signal of the train itself, and does not pay attention to the actual operation demand of the driver, the output fault code and processing suggestion are not related to the fault content that the driver urgently needs to handle, that is, the operation intention of the driver is poor.

[0006] (3) In the case where the equipment itself has no fault, the system cannot remind and correct the problem caused by improper operation of the driver himself.

[0007] (4) In the prior art, the fault content itself is generally sorted according to the priority, without considering the constraint relationship between the faults and the constraint relationship between the repair actions to be executed for repairing the faults, so that when the driver disposes in order according to the priority of the fault content itself, the disposal order may violate the constraint relationship between the faults or the constraint relationship between the repair actions, resulting in that the fault cannot be repaired or a new fault occurs due to the repair operation itself in a particular case.

[0054] S4: prioritize the fault codes and the emergency treatment suggestions;

[0055] Specifically, the multiple emergency treatment suggestions in the multiple fault codes obtained at present are prioritized, the priority levels of the fault codes and the emergency treatment suggestions are determined according to the influence of the faults corresponding to the fault codes, the influence caused by the emergency treatment suggestions, and the constraint relationship between the faults corresponding to different fault codes, and the fault codes and the emergency treatment suggestions are sorted according to the priority levels;

[0056] The application is to ensure the rapid and accurate disposal of faults in train operation. According to the influence of the fault corresponding to the fault code, the influence caused by the fault emergency disposal suggestion, and the constraint relationship between the faults corresponding to different fault codes, the priority level of the fault code and the fault emergency disposal is determined to be sorted, and the fault processing suggestion is output according to the priority sorting order. Instead of outputting multiple fault processing suggestions at a time, the sequence of the repair actions performed by the driver when executing the operation steps in the fault processing suggestion may violate the constraint relationship between the repair actions, resulting in the failure to repair the fault or the occurrence of a new fault due to the repair operation itself in certain cases. Further, the driver ensures to follow the train on-board pop-up information to interact in sequence and execute the steps of the multiple fault processing suggestions in order until the fault is repaired, so as to achieve clear indication of the fault processing suggestion, guide the driver to perform emergency disposal, and greatly improve the real-time response efficiency and level of sudden faults.

[0057] S5: Display and output the fault code and the fault emergency disposal suggestion according to the priority sorting.

[0058] Specifically, the display and output of the fault code and the fault emergency disposal suggestion are performed according to the priority sorting of the fault code and the fault emergency disposal suggestion. The output content specifically includes: sorting according to the priority of the fault code and the fault emergency disposal suggestion; the fault emergency disposal suggestion includes multiple disposal operation suggestions; sorting and outputting the fault code and the fault emergency disposal suggestion according to the response level of the target fault code, the constraint relationship between the target fault codes, and the constraint relationship between the target fault emergency disposal suggestions; displaying the text information of the fault code, the fault name, and the fault emergency disposal suggestion with the highest priority in a pop-up box on the train human-computer interaction display, such as Figure 2 As shown, the driver is informed of the current problems and disposal suggestions. The fault code is displayed above the pop-up box, the fault emergency disposal operation steps are displayed below the pop-up box, and the confirmation button is displayed on the right side of the pop-up box. The pop-up box will disappear only after the driver clicks the confirmation button on the train human-computer interaction display. If multiple faults exist at the same time, the driver will be displayed with the next fault code, fault name, and fault emergency disposal suggestion with a lower priority after confirmation, until all faults are correctly processed.

[0059] In some embodiments, as shown in Figure 3 The step S1 further includes the steps of:

[0060] S11: continuously monitor the plurality of instruction signals, analyze the arrangement combination relationship of the plurality of instruction signals, and match the arrangement combination relationship of the plurality of instruction signals with a pre-stored instruction signal arrangement combination template; when the arrangement combination relationship of the plurality of instruction signals matches at least one pre-set instruction signal arrangement combination template, output the driver operation intention corresponding to the matched instruction signal arrangement combination template as the current operation intention of the driver;

[0061] Specifically, the plurality of instruction signals are transmitted to the train control unit in real time through the train control network, the train control unit continuously monitors the plurality of instruction signals, and analyzes the arrangement combination relationship of the plurality of instruction signals. The system pre-stores instruction signal arrangement combination templates, each of which corresponds to a train driver operation condition. When the arrangement combination relationship of the plurality of instruction signals matches at least one pre-set instruction signal arrangement combination template, the current operation intention of the driver can be obtained according to the matched pre-set instruction signal arrangement combination template.

[0062] Among them, the current operation intention of the driver includes: the driver's intention to operate the opening / closing door, the driver's intention to operate the rising / falling bow, the driver's intention to operate the traction / braking, the driver's intention to operate the closing / opening vacuum circuit breaker, the driver's intention to operate the emergency stop, and the driver's intention to operate the bypass switch.

[0063] In this embodiment, the arrangement combination relationship of the plurality of instruction signals is determined based on the signal type, signal value, and signal timing.

[0064] The present application continuously monitors the plurality of instruction signals, analyzes the arrangement combination relationship of the plurality of instruction signals, matches the arrangement combination relationship of the plurality of instruction signals with a plurality of pre-set instruction signal arrangement combination templates pre-stored, and when the arrangement combination relationship of the plurality of instruction signals matches at least one pre-set instruction signal arrangement combination template, outputs the driver operation intention corresponding to the matched instruction signal arrangement combination template as the current operation intention of the driver. The operation intention of the driver is accurately determined through the arrangement combination relationship of the plurality of instruction signals.

[0065] S12: continuously monitor the plurality of feedback signals, obtain one or more feedback signal detection models matched with the operation intention from the pre-set storage module based on the current operation intention of the driver, and perform correlation analysis on the plurality of feedback signals based on the one or more detection models to determine whether the intention of the driver operation is achieved.

[0066] Specifically, when the driver performs a specific operation, the train control system generates corresponding feedback signals in response to the operation. When multiple feedback signals are transmitted in real time to the train control unit through the train control network, the train control unit continuously monitors the input multiple feedback signals, and acquires one or more feedback signal detection models matching the operation intention from the preset storage module according to the current operation intention of the driver, and performs correlation analysis on the multiple feedback signals by using the one or more detection models. If the correlation analysis of the feedback signal detection model corresponding to the current operation intention of the driver on the monitored multiple feedback signals is incorrect, the current operation of the driver does not get system response, and the intention of the driver's operation is not achieved. On the contrary, if the correlation analysis of the feedback signal detection model corresponding to the current operation intention of the driver on the monitored multiple feedback signals is correct, the current operation of the driver gets system response, and the intention of the driver's operation is achieved.

[0067] In some embodiments, as shown in Figure 4 The step S2 further includes the following steps:

[0068] S21: determining the reason for failure to achieve according to the multiple feedback signals and the current operation intention of the driver;

[0069] Specifically, the system pre-stores a standard feedback signal template, which includes all possible combinations of one or more feedback signals obtained by the train in response to the current operation of the driver. The corresponding standard feedback signal template is determined according to the current operation intention of the driver, the combination relationship of the multiple feedback signals is analyzed and compared with the standard feedback signal template, the inconsistent content of the feedback signal combination relationship and the standard feedback signal template is determined, and the reason for failure to achieve the current operation intention of the driver is determined according to the inconsistent content.

[0070] S22: determining the target fault code and the corresponding target fault content according to the current operation intention of the driver and the reason for failure to achieve.

[0071] Specifically, a plurality of corresponding relationships among fault content, fault code, operation intention and reason for failure to achieve are pre-set, the current operation intention of the driver and the reason for failure to achieve are matched with the pre-set plurality of corresponding relationships among fault content, fault code, operation intention and reason for failure to achieve, and the corresponding target fault code and the corresponding target fault content corresponding to the current operation intention of the driver and the reason for failure to achieve are determined.

[0072] In some embodiments, as shown in Figure 5 Before the step S1, the following steps are further included:

[0073] The digital signals of the low-voltage control circuit of the train and the analog signals of the voltage and current in the running of the train are collected in real time, and the digital signals and the analog signals are classified and converted into a plurality of instruction signals and a plurality of feedback signals respectively.

[0074] Specifically, the high and low level signals of the 110V low-voltage control circuit of the train and the electrical signals of the voltage and current in the running of the train are collected, the functions thereof are classified by a signal conversion unit of the train control system, and the functions are converted into a plurality of instruction signals and a plurality of feedback signals respectively.
