[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0046] In an exemplary embodiment, as shown in Figure 1 A train fault handling method is provided, applied to a locomotive control unit of a whole train, including the following steps S102 to S108. Wherein:

[0047] Step S102, receiving operation fault information sent by each train in the whole train; the operation fault information is sent when the running state of each train triggers a target fault condition.

[0048] The whole train is a complete train set composed of multiple train sets, and each train set can run cooperatively; the running fault information is related information generated when each train set appears a fault during running, which can include fault type, position, etc.; the running state is a real-time condition of each train set during running, which can include running speed, braking state, etc.; and the target fault condition is a preset standard for judging whether the train appears a fault, and the train is determined to have a fault when the running state meets the condition.

[0049] In step S104, the received running fault information is matched with the preset multiple instruction generation conditions.

[0050] The preset multiple instruction generation conditions are multiple standards set in advance for judging what kind of instruction should be generated, and correspond to different fault severities; and the matching is comparing the received running fault information with the preset instruction generation conditions to determine which instruction condition the running fault information of the train meets.

[0051] In step S106, if the received running fault information triggers the first instruction generation condition, a first fault train is determined, and a punishment braking instruction is sent to the first fault train.

[0052] The first instruction generation condition is a preset instruction generation standard corresponding to a relatively light fault condition; the first fault train is a train triggering the first instruction generation condition; and the punishment braking instruction is a braking instruction sent to the first fault train, which has a relatively weak braking strength and is used for properly controlling the fault train.

[0053] In step S108, if the received running fault information triggers the second instruction generation condition, a second fault train is determined, and an emergency braking instruction is sent to the second fault train; and the second instruction generation condition has a severity greater than that of the first instruction generation condition.

[0054] The second instruction generation condition is another preset instruction generation standard different from the first instruction generation condition, has a severity higher than that of the first instruction generation condition, and corresponds to a more serious fault condition; the second fault train is a train triggering the second instruction generation condition; and the emergency braking instruction is a braking instruction sent to the second fault train, which has a large braking strength and is used for quickly stopping the train to ensure safety in a serious fault.

[0055] In the train fault processing method, during train fault processing, the locomotive control unit of the entire train receives running fault information sent by each train in the entire train; the running fault information is sent when the running state of each train triggers a target fault condition; the received running fault information is matched with a plurality of preset instruction generation conditions; if the received running fault information triggers a first instruction generation condition, a first fault train is determined, and a penalty braking instruction is sent to the first fault train; if the received running fault information triggers a second instruction generation condition, a second fault train is determined, and an emergency braking instruction is sent to the second fault train; the severity of the second instruction generation condition is greater than that of the first instruction generation condition. Through the above process, the locomotive control unit of the entire train realizes the matching of the running fault information and the plurality of preset instruction generation conditions, and can match different instruction generation conditions according to the fault severity. The second instruction corresponding to the higher severity corresponds to emergency braking, and the first instruction corresponds to penalty braking, so that the fault processing is more targeted. In the case of more serious faults, emergency braking can maximize safety, and in the case of relatively minor faults, penalty braking can achieve effective control, avoid excessive braking affecting operation efficiency, and achieve the beneficial effects of improving train braking effect and reducing maintenance cost.

[0056] In one embodiment, the type of running fault information includes train signal loss and train pipe pressure loss; the target fault condition is that the timing duration corresponding to the running fault information is outside the preset time threshold; the first instruction generation condition is that the running fault information of at least two trains is train signal loss within a first preset time, or the running fault information of at least two trains is train pipe pressure loss; and the second instruction generation condition is that the running fault information of at least two trains includes train signal loss and train pipe pressure loss within a second preset time.

[0057] Wherein, the train signal loss refers to the interruption of communication signals between trains or between trains and the control center, which leads to the failure of normal information transmission and may affect train scheduling and coordinated operation, which may be caused by signal equipment failure, electromagnetic interference or line problems, etc. Train pipe pressure loss refers to the abnormal drop of train pipe pressure, which affects the normal play of braking function and threatens train driving safety, which is usually related to pipe leakage, valve failure and other factors. The preset time threshold refers to the time condition for each train to report to the control unit to realize the level fault operation, which can be 5 seconds.

[0058] More, the first preset time is a specific time range set for the first instruction, which is a time basis for determining whether to trigger the first instruction; the at least two trains ensure that the corresponding instruction is triggered by the fault of the train other than the single train; the train signal loss is that when the fault information of the train signal loss of the at least two trains occurs within the first preset time; the train pipe pressure loss is that when the fault information of the train pipe pressure loss of the at least two trains occurs within the first preset time, the first instruction generation condition is also met; the second preset time is a time basis for determining whether to trigger the second instruction; the at least two trains ensure the universality of the fault; the train signal loss and the train pipe pressure loss are included to indicate that the fault information of each fault train needs to contain the two types, indicating that the fault condition is more complex and serious, and therefore a higher level of braking instruction needs to be triggered.

[0059] Further, when one train signal loss and one train pipe pressure loss occur, the second instruction is also generated, and the emergency braking instruction is triggered, so that the train can be braked in time.

[0060] In an exemplary embodiment, as shown in Figure 2 applied to any train in the whole train set, comprising steps S202 to S206, wherein:

[0061] S202, when the running state of the train triggers the target fault condition, the running fault information is sent to the locomotive control unit of the whole train set; the locomotive control unit is used for receiving the running fault information sent by each train in the whole train set, matching the received running fault information with the preset multiple instruction generation conditions, if the received running fault information triggers the first instruction generation condition, determining the first fault train, sending the punishment braking instruction to the first fault train; if the received running fault information triggers the second instruction generation condition, determining the second fault train, sending the emergency braking instruction to the second fault train; the severity of the second instruction generation condition is greater than that of the first instruction generation condition; S204, when the punishment braking instruction returned by the locomotive control unit is received, the punishment braking operation is performed on the train; S206, when the emergency braking instruction returned by the locomotive control unit is received, the emergency braking operation is performed on the train.

[0062] The penalty braking instruction is a braking instruction issued by the locomotive control unit for a relatively less serious fault (triggering the first instruction generation condition), the braking strength and emergency response level of which are lower than the emergency braking, and is used for moderately controlling the fault train to limit its running state; the current train is a specific train receiving the braking instruction and executing the braking operation, and is the main body of fault handling; the execution of the penalty braking operation is a specific braking action of the fault train after receiving the penalty braking instruction; the emergency braking instruction is a braking instruction issued by the locomotive control unit for a serious fault (triggering the second instruction generation condition), the braking strength of which is the largest and the response priority is the highest, and the purpose is to quickly stop the train in an emergency and minimize the safety risk; the execution of the emergency braking operation is a key action of the fault train after receiving the emergency braking instruction, which starts the braking system to apply the maximum braking force to stop the train running in the shortest distance.

[0063] In the embodiment, any train in the whole train set sends the running fault information to the locomotive control unit of the whole train set when monitoring that the running state of the current train triggers the target fault condition; the locomotive control unit is used for receiving the running fault information sent by each train in the whole train set, matching the received running fault information with the preset multiple instruction generation conditions, the instruction matching process is the same as described above, and when the penalty braking instruction returned by the locomotive control unit is received, the penalty braking operation is executed on the current train; in the above process, the matching of the running fault information with the preset multiple instruction generation conditions is realized by any train in the whole train set, and different instruction generation conditions can be matched according to the fault severity, the second instruction corresponding to the emergency braking and the first instruction corresponding to the penalty braking for the higher severity, so that the fault handling is more targeted, the safety can be maximally guaranteed by the emergency braking in the relatively serious fault, the effective control can be realized by the penalty braking in the relatively slight fault, the over-braking affecting the running efficiency is avoided, and the beneficial effects of improving the braking effect of the train and reducing the maintenance cost are achieved.

[0064] In one embodiment, the type of the running fault information includes train signal loss and train pipe pressure loss; the method further includes: automatically controlling the current train to execute the penalty braking operation when it is monitored that the running state of the current train is the train signal loss or the train pipe pressure loss within the first preset time; automatically controlling the current train to execute the emergency braking operation when it is monitored that the running state of the current train is the train signal loss or the train pipe pressure loss outside the first preset time; automatically controlling the current train to execute the penalty braking operation when it is monitored that the running state of at least two other trains is the train signal loss or the train pipe pressure loss within the first preset time; and automatically controlling the current train to execute the emergency braking operation when it is monitored that the running state of at least two other trains is the train signal loss or the train pipe pressure loss outside the first preset time.

[0065] The first preset time is a specific time range set in advance, which is a time limit for distinguishing fault handling methods, and is used to define different braking strategies that the train should adopt when the same type of fault occurs at different times. The length of time can be pre-configured according to the train operation characteristics and safety requirements; the train is the specific train that monitors the abnormal running state and executes the braking operation, and is the direct subject of fault monitoring and braking execution; the running state is the real-time driving condition parameter and system state of the train; the automatic control refers to a mechanism that the train can trigger and execute the braking operation autonomously according to the preset rules without human intervention; and the first preset time is beyond the pre-set time range.

[0066] In this embodiment, by adopting differential processing for train signal loss and train pipe pressure loss at different times, the limitations of a single braking mode are avoided, the flexibility of fault response is improved, and the automatic control mechanism allows the train to autonomously execute the braking operation without human intervention, greatly shortening the fault response time and reducing the risk of human delay.

[0067] Further, in one embodiment, after the automatic control of the train to execute the emergency braking operation, the method further comprises: generating a signal loss message when monitoring the train or receiving the running state of at least two other trains as train signal loss; generating a pipe pressure loss message when monitoring the train or receiving the running state of at least two other trains as train pipe pressure loss; and sending the signal loss message or the pipe pressure loss message to the locomotive control unit.

[0068] Further, in one embodiment, after the automatic control of the train to execute the emergency braking operation, the method further comprises: generating a signal loss message when monitoring the train or receiving the running state of at least two other trains as train signal loss; generating a pipe pressure loss message when monitoring the train or receiving the running state of at least two other trains as train pipe pressure loss; and sending the signal loss message or the pipe pressure loss message to the locomotive control unit.

[0069] Further, the signal loss message is a standardized information carrier for recording and transmitting the train signal loss condition, which can include fault train identification, fault occurrence time and other key contents, to facilitate the locomotive control unit to master the specific situation of the signal loss fault; the pipe pressure loss message is a standardized information carrier for recording and transmitting the train pipe pressure loss condition, which can include pressure abnormal value, fault position and other information, to provide basis for the locomotive control unit to analyze the braking system fault; and the sending to the locomotive control unit is to deliver the generated message to the control center of the whole train, so that the locomotive control unit can summarize the fault information of each train and provide comprehensive data support for subsequent fault troubleshooting, forming a closed loop of fault handling.

[0070] In this embodiment, by receiving the fault states of at least two other trains, it is ensured that the fault information collection is universal, and the misjudgment caused by occasional abnormalities of a single train is avoided, and the information reliability is improved; by respectively generating a signal loss message and a pipe pressure loss message for the two types of core faults of signal loss and pipe pressure loss, the fault information is classified clearly and standardized in content, which facilitates the locomotive control unit to quickly and accurately identify the fault type and the involved range, and by feeding back the message to the locomotive control unit, complete data support can be provided for subsequent whole train scheduling adjustment, and the train operation efficiency is improved.

[0071] The present application provides a train fault processing method. In order to better understand the process of the above train fault processing method, the specific process of a train fault processing method of the present application is described in detail as follows: Figure 3

[0075] Further, when the vehicle receives the signal loss fault message of other vehicles, at this time if the signal loss timer does not exceed 5s, the train automatically implements the punishment brake, at this time if the pressure loss timer does not exceed 5s, the train automatically implements the emergency brake, when the signal loss timer and the pressure loss timer do not exceed 5s, the emergency brake is implemented, when the signal loss timer and the pressure loss timer exceed 5s, the signal loss fault timer starts timing; When the vehicle receives the train pipe pressure loss fault message of other vehicles, at this time if the train pipe pressure loss timer does not exceed 5s, the train automatically implements the punishment brake, at this time if the signal loss timer does not exceed 5s, the train automatically implements the emergency brake, when the signal loss timer and the pressure loss timer do not exceed 5s, the emergency brake is implemented, when the signal loss timer and the pressure loss timer exceed 5s, the train pipe pressure loss fault timer starts timing.

[0076] Further, the whole set of trains is provided with a control board card and a pressure detection and brake control module, the control board card is responsible for receiving the brake instruction of the locomotive control unit, and performing the train signal and train pipe pressure loss diagnosis, and sending the status message of itself to the locomotive control unit; The locomotive control unit is provided with a control board card control module, the control board card is responsible for receiving the vehicle brake state reply, and sending appropriate instructions according to the train signal and the loss of the vehicle.

[0077] Through the above embodiments, the train can be ensured to implement correct punishment or emergency braking when a system fault occurs, to ensure safe parking of the train, neither because of train cable breakage, the rear vehicle does not generate braking force due to not receiving train braking, nor because of a single fault (train signal fault or train pipe pressure signal), causing emergency braking to affect the order of train operation (classifying the single fault such as train signal fault or train pipe pressure signal fault as a non-serious fault, only triggering punishment braking, the punishment braking strength is moderate, only moderately controlling the fault vehicle, and will not cause the whole train to stop urgently, thereby reducing the interference to the overall train operation order), when a serious accident such as train derailment or broken hook occurs, the train pipe and train signal will be lost at the same time, at which time the system will automatically implement emergency braking to ensure parking in the shortest time, and ensure the timeliness and accuracy of train fault judgment.

[0078] In addition, the train signal loss fault and the train pipe pressure signal can also be divided into two categories, only one type of fault triggers train punishment braking, and only when both types of faults occur simultaneously does emergency braking occur. The alternative solutions that can be implemented are as follows: the train signal loss fault and the train pipe pressure signal are divided into one category, and when the train signal loss fault or the train pipe pressure signal loss occurs, emergency braking occurs, at which time the fault logic is relatively simple, but the train can still be ensured to stop; the train signal loss fault and the train pipe pressure signal are divided into one category, and when the train signal loss fault or the train pipe pressure signal loss occurs, punishment braking occurs, at which time the fault logic is relatively simple, but the train can still be ensured to stop.
