Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Fig. 1 is a schematic flow chart of a method for handling emergency braking of a train for testing a fully automatic running system according to an embodiment of the present application, and as shown in fig. 1, the embodiment of the present application provides a method for handling emergency braking of a train for testing a fully automatic running system. The method comprises the following steps:
and step 101, the TIAS receives the reason that the train currently carries out emergency braking and is sent by the vehicle-mounted controller VOBC.
Specifically, in the embodiment of the application, the On-Board signal system tester needs to record the emergency braking time and the stock track, and thoroughly record the operation performed by the train and the personnel On the Vehicle before the braking occurs, and record the event reported by the driver's cab On-Board Controller (VOBC) man-machine screen and the train control and management system (Train Control and Management System, TCMS) screen after the braking occurs.
When the man-machine screen of the VOBC outputs the train emergency braking, the VOBC reports the reason that the train currently applies the emergency braking to the central TIAS, and the TIAS receives the reason that the train sent by the VOBC currently applies the emergency braking. There may be various reasons for implementing emergency braking currently, for example, table 1 is a fault reason for causing emergency braking of a train, and as shown in table 1, different fault reasons have a fault typical scene and a fault processing mode corresponding to the fault reasons, so as to help signal testers and vehicle personnel on the train to quickly check the reasons and alleviate the reasons.
Table 1 causes of failure leading to emergency braking of the train
And 102, automatically relieving the emergency braking of the train according to the reason that the emergency braking is currently implemented by the train.
Specifically, after the reason for the current implementation of the emergency braking of the train is obtained, the emergency braking of the train is automatically relieved according to the reason.
In this embodiment of the present application, when the VOBC meets a certain condition, automatic emergency braking of the train may be successfully released, for example, table 2 is an emergency braking cause and an automatic release condition table, and as shown in table 2, some emergency braking causes may be automatically released to complete emergency braking recovery, where whether the fault cause is automatically released after being eliminated is judged by the VOBC to judge whether the fault cause may be automatically released, so that after the automatic recovery of the emergency braking condition, the fault is released without manual or remote participation.
TABLE 2 Emergency brake cause and automatic relief Condition Meter
And 103, under the condition of failure of automatic release, remotely and manually releasing the emergency braking of the train according to an emergency braking release instruction sent to the VOBC by the TIAS.
Specifically, in the case of failure in automatic release of emergency braking of a train, the TIAS transmits an emergency braking release instruction to the VOBC, through which emergency braking of the train is remotely and manually released.
Optionally, the remote manual mitigation includes remote mitigation of the fault and/or remote manual bypass of the fault.
In the embodiment of the application, two methods for judging that the emergency braking cannot be automatically relieved by a signal tester are mainly adopted, one method is that a word of ' the emergency braking cannot be relieved ' or other words with similar meanings appear by observing a driver's cab VOBC man-machine screen; a serial port printing is carried out through a VOBCATP cabinet, and an on-vehicle record analysis tool is connected to analyze the reason of emergency braking, so that specific reasons and whether information can be relieved or not can be checked in the reason of emergency braking.
In this embodiment of the application, the devices in the full-automatic running system capable of automatically alleviating (i.e. automatically resetting) and remotely and manually alleviating (i.e. remotely and manually resetting) are as follows: a head-end train automatic operation system (Automatic Train Operation, ATO) power supply circuit breaker, a tail-end ATO power supply circuit breaker, and the like. The behavior of the headend ATO supply circuit breaker after power failure includes: when the train is in a full-automatic driving mode (Full Automatic Mode, FAM), the headend ATO is powered off, the train is emergency, and after the power-on fault is relieved, the train waits for the center to confirm and then gets off. The actions of the tail-end ATO power supply circuit breaker after power failure include: when the train is in the FAM mode, the tail end ATO is powered off, the control end monitors the fault of the tail end ATO, gives an alarm to the center, and runs to the terminal station to wait for the tail end ATO to be powered on and continue to run after being normal.
Automatic mitigation and remote manual mitigation resettable vehicle devices include: cab activation circuit breakers, TMC car pantograph control circuit breakers, MP car pantograph control circuit breakers, high-speed circuit breakers, air compressor start control circuit breakers, train control circuit breakers, safety loop power circuit breakers, travel section host circuit breakers, fire alarm circuit breakers, TRU circuit breakers, ATP1 circuit breakers, VOBC total circuit breakers, ATP2 circuit breakers, AT0+BTM circuit breakers, output circuit breakers, communication storage equipment circuit breakers, TAU1 circuit breakers, TAU2 circuit breakers, communication vehicle-mounted station circuit breakers, gate control circuit breakers, train gate control circuit breakers, vehicle door closed circuit breakers, NVR circuit breakers, PIS cab host circuit breakers, PIS passenger room host circuit breakers and the like.
And 104, carrying out local manual release on the emergency braking of the train under the condition that the release of the emergency braking release instruction fails.
Specifically, in the event of failure of remote manual mitigation, emergency braking of the train is locally manually mitigated, i.e., handled locally by the driver.
According to the train emergency braking coping method for the full-automatic running system test, the emergency braking reason and the relieving condition of the train are obtained in real time based on interaction between the TIAS and the VOBC, faults which cause emergency braking are relieved through multiple dimensions, real-time monitoring and timely relieving of the train emergency braking in the full-automatic running system are achieved, and safety of the train in the full-automatic running system is improved.
In some embodiments, the automatically relieving the emergency braking of the train according to the reason that the train currently applies the emergency braking comprises:
determining that the reason for the train currently implementing emergency braking is that the reset-allowed equipment fails;
under the conditions that the train is in a full-automatic driving mode or a full-automatic creeping mode, at zero speed and the driver cover plate is closed, the train is automatically reset once.
Specifically, the emergency braking of the train is automatically relieved according to the reason that the train currently applies the emergency braking, whether the reason that the train currently applies the emergency braking is a fault on equipment allowing resetting is firstly determined, if yes, the automatic relief/resetting can be judged, and then the train can be automatically reset only once under the condition that the train is in a full-automatic driving mode or a full-automatic creeping mode, the driver cover plate is closed at zero speed. If the reason for the current emergency braking of the train is not the fault occurring on the equipment which allows resetting, the fault is automatically relieved, and the fault is continuously reset by a remote manual relief mode or a local manual relief mode.
According to the train emergency braking coping method for the full-automatic running system test, the emergency braking reason and the relieving condition of the train are obtained in real time based on interaction between the TIAS and the VOBC, and the faults causing the emergency braking are automatically relieved remotely, so that the real-time monitoring and timely relieving of the train emergency braking in the full-automatic running system are realized, and the running safety of the train is guaranteed.
In some embodiments, before the remote manual alleviation of emergency braking of a train according to the emergency braking alleviation instruction sent by the TIAS to the VOBC, the method further comprises:
the TIAS receives an emergency braking reason sent by the VOBC; the emergency braking cause is reported to the VOBC by the TCMS.
Specifically, when the vehicle outputs an emergency braking that cannot be automatically released, i.e., fails in automatic release, the VOBC forwards the emergency braking cause reported by the TCMS to the central TIAS, and then the TIAS generates an emergency braking release instruction according to the emergency braking cause, and sends the emergency braking release instruction to the VOBC for remote manual release.
According to the train emergency braking coping method for the full-automatic running system test, the emergency braking reason and the relieving condition of the train are obtained in real time based on interaction among the TIAS, the VOBC and the TCMS, and the faults which cause the emergency braking are relieved remotely and manually through the emergency braking relieving instruction, so that the real-time monitoring and timely relieving of the train emergency braking in the full-automatic running system are realized, and the running safety of the train is guaranteed.
In some embodiments, the emergency brake mitigation command includes a remote reset command; the remote manual alleviation of emergency braking of a train according to an emergency braking alleviation instruction sent by the TIAS to the VOBC comprises:
under the condition that the train is in a full-automatic driving mode or a full-automatic creeping mode, at zero speed and the driver cover plate is closed, forwarding a remote reset instruction sent by the TIAS to a train network control and monitoring system TCMS by utilizing the VOBC;
and the TCMS executes one-time fault resetting on faults which cause emergency braking of the train according to the remote resetting instruction, and responds to a fault resetting result.
Specifically, the remote manual mitigation means that only when the train is in FAM or full-automatic peristaltic mode (Creep Automatic Model, CAM) (the signal system is normally communicated with TCMS), the train is at zero speed and the driver's cover is closed, the remote reset can be performed through the central TIAS, i.e. the TIAS sends a remote reset instruction to the VOBC, the VOBC forwards the remote reset instruction to the TCMS and performs fault reset, a fault reset result is generated and responded to the VOBC, the vehicle TCMS responds to the remote reset instruction only 1 time, and the TCMS is instructed not to execute for a plurality of times.
According to the train emergency braking coping method for the full-automatic running system test, the emergency braking reason and the relieving condition of the train are obtained in real time based on interaction among the TIAS, the VOBC and the TCMS, and the faults which cause the emergency braking are remotely reset through the remote resetting instruction, so that the real-time monitoring and timely relieving of the train emergency braking in the full-automatic running system are realized, and the running safety of the train is guaranteed.
In some embodiments, the emergency brake mitigation command further includes a remote bypass command; the remote manual alleviation of emergency braking of a train according to an emergency braking alleviation instruction sent by the TIAS to the VOBC comprises:
and under the condition that the fault reset result is a reset failure, the TIAS remote manual bypass causes the fault of train emergency braking.
Specifically, if the fault reset result is a reset failure, that is, if the fault that causes the train emergency braking cannot be reset remotely, the central tia s needs to bypass remotely and manually to cause the train emergency braking fault.
According to the train emergency braking coping method for the full-automatic running system test, the emergency braking reason and the relieving condition of the train are obtained in real time based on interaction between the TIAS and the VOBC, and the fault which cannot be reset remotely is bypassed manually, so that real-time monitoring and timely relieving of the train emergency braking in the full-automatic running system are realized, and the running safety of the train is guaranteed.
In some embodiments, in the event that the cause of the train currently implementing emergency braking is a fire alarm, the method further comprises:
transmitting an in-car picture of the train, shot by the vehicle-mounted camera, at a fire alarm position to the TIAS;
and confirming that the cause of the fire alarm of the train is non-fire according to the picture in the train where the fire alarm of the train occurs.
Specifically, for emergency braking caused by vehicle fire alarm, an in-car picture of a train where the fire alarm occurs, which is shot by a vehicle-mounted camera, is sent to the TIAS in time, and when the central TIAS vehicle regulates that the cause of the fire alarm of the train is non-fire or emergency according to the in-car picture of the train where the fire alarm occurs, the central TIAS vehicle regulates that the fire alarm of the train is forwarded to the vehicle TCMS through the vehicle-mounted VOBC, and the vehicle TCMS is responsible for executing fault reset.
According to the train emergency braking coping method for the full-automatic running system test, whether the cause of the fire alarm is fire or not is accurately identified by timely acquiring the picture of the fire alarm part of the train, if not, remote resetting is carried out, real-time monitoring and timely relieving of the train emergency braking in the full-automatic running system are achieved, and train running safety is guaranteed.
In some embodiments, the method further comprises:

and carrying out vehicle-mounted broadcasting on passengers by the train condition in a manual broadcasting mode, and determining whether to continue to carry out full-automatic operation system test according to the train condition.
Specifically, in the embodiment of the application, the personal safety condition of personnel on the vehicle is also monitored, the personnel on the vehicle can use the vehicle-mounted CCTV to check the condition (image) in the vehicle shot by the vehicle-mounted camera, and the center can manually call the vehicle-mounted CCTV through TIAS to check the condition in the vehicle shot by the vehicle-mounted camera, for example, whether the conditions such as collision, falling injury and the like occur; meanwhile, TIAS sends the passenger the train exterior image shot by the interval camera corresponding to the interval position of the train, for example, whether emergency braking occurs or not, and the center passenger can check through CCTV; train conditions (including in-car and out-of-car images) are monitored by CCTV and corresponding on-board broadcasts are made to passengers by manual broadcasts.
