Detailed Description

In the process of implementing the application, the inventor finds that along with the development of rail transit, the full-automatic unmanned technology of rail transit is more mature, and under the normal operation condition, the automatic equipment can replace a driver to automatically drive a train to operate on an operation route in a full-line mode at present. Before the unmanned train is delivered out of a warehouse and is sent out every day, the unmanned train firstly needs to be automatically awakened according to an operation plan, dynamic testing is carried out on the train when the unmanned train is awakened, and if the dynamic testing fails, the automatic awakening fails.

In the existing scheme, most of the existing schemes adopt a Train operation mode of a driver on duty, namely, a worker maintains and overhauls the Train before the Train is delivered out of a warehouse, the intelligent degree of the scheme is not high, the dynamic test of the Train is realized by a signal System or manual work through hard line inspection, a Train and vehicle Control management System (TCMS) hardly participates, the state detection of each device of the Train is manually inspected after being electrified, the remote Control automatic test cannot be realized, more manpower and material resources are required, and the maintenance and operation cost is higher.

In addition, the current dynamic test for the automatic wake-up of the unmanned train is mainly realized by an information interaction and instruction sending module of a Zone Controller (ZC) of a signal system, and a method for dynamically testing the automatic wake-up of the vehicle by a vehicle and a vehicle control management system is not used.

In order to solve the above problem, an embodiment of the present application provides a train dynamic test method and a train, where the method is applied to the train, and the method includes: the VOBC receives a train awakening instruction, powers on the train and starts a train-mounted subsystem of the train; after the static test is successful, the VOBC judges whether the train meets the dynamic test condition; if the dynamic test condition is met, the VOBC applies for dynamic test authorization of the train; after obtaining the authorization, the VOBC initiates a dynamic test instruction; and the TCMS dynamically tests the train through the dynamic test instruction, wherein the dynamic test comprises a jump test. The train automatic test system has the advantages that the train is automatically awakened through the TCMS and the VOBC, so that remote automatic dynamic test and check before the unmanned train is dispatched are realized, the intelligent degree of the train is improved, the operation and maintenance cost of the train is reduced, and meanwhile, safety guarantee is provided for the dispatching and operation of the train.

In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict.

In the unmanned mode, an Automatic Train monitoring system (ATS) of the control center automatically sends an Automatic wake-up instruction to the Train according to a Train schedule, and after the Train receives the Automatic wake-up instruction, the Train is electrified and the vehicle-mounted subsystems are started, so that the Automatic wake-up control of comprehensive self-detection test is performed on the vehicle-mounted subsystems. The train-mounted subsystem of the train mainly comprises a traction system (TCU), an auxiliary system, a brake system (BCU), a vehicle door system, an air conditioning system, a smoke and fire alarm system, a Passenger Information System (PIS), a storage battery management system, a bow net monitoring system, an illuminating system, an obstacle detection system, a walking part online detection system and the like.

After all automatic awakening programs are finished, the train reports an automatic awakening result to the ATS, if the automatic awakening is unsuccessful, a control center (OCC) performs manual intervention according to fault information, and if the automatic awakening of the train is successful, the train can be put into operation according to an operation plan and waits for a new command sent by a signal system.

Optionally, during the automatic wake-up process of the train, the train also needs to be dynamically tested. After the static test of the train is successful, the train enters the test of the next stage of the automatic awakening process, namely the dynamic test, in the dynamic test process, the train can feed back the test result of each stage of the dynamic test to the control center OCC in time according to the test condition, if the dynamic test is successful, the train enters the next stage of the automatic awakening process, and if the dynamic test is unsuccessful, the control center OCC performs manual intervention according to the fault information result fed back by the train until the dynamic test of the train is successful.

Referring to fig. 1, fig. 1 is a flowchart of a dynamic train testing method provided in an embodiment of the present application, where the method is applied to a train, the train includes a train, a train control management system TCMS, and a vehicle controller VOBC, and the method includes:

and step S11, the VOBC receives the train awakening instruction, powers on the train and starts each vehicle-mounted subsystem of the train.

And step S12, after the static test is successful, the VOBC judges whether the train meets the dynamic test condition.

And S13, if the dynamic test conditions are met, the VOBC applies for dynamic test authorization of the train.

Step S14, after obtaining the authorization, the VOBC initiates a dynamic test instruction.

And S15, the TCMS performs dynamic test on the train through the dynamic test instruction.

Wherein the dynamic test comprises a jump test.

The TCMS and the VOBC carry out automatic awakening dynamic test on the train, so that remote automatic dynamic test and check before the unmanned train is dispatched are realized, the intelligent degree of the train is improved, the operation and maintenance cost of the train is reduced, and meanwhile, safety guarantee is provided for the dispatching and operation of the train.

In this embodiment, in the dynamic test process when the train is automatically awakened, certain dynamic test conditions need to be satisfied. As shown in fig. 2, fig. 2 is a schematic diagram of dynamic test conditions provided in the embodiment of the present application. In this embodiment, after the static test is successful, the vehicle-mounted controller VOBC comprehensively judges the self-detection state and the train dynamic test condition state judged by the TCMS, if the dynamic test condition is satisfied, the VOBC applies for train dynamic test authorization to the control center OCC, and after obtaining the authorization, the VOBC initiates a dynamic test instruction to perform the dynamic test; and if the condition is not met, the VOBC feeds back the reason and the result of the train not meeting the test condition to the control center.

Optionally, in this embodiment, the dynamic test conditions include that the preset train mode is an unattended train operation UTO mode, the VOBC is successfully powered on and self-checked, the TCMS feeds back the train self-check successfully, the TCMS feeds back the direction handle at 0 bit, the TCMS feeds back the main control handle at 0 bit, the VOBC detects that the driver key is at the OFF bit, the VOBC at both ends of the train is normally communicated, the manually operated wake-up button is powered on, the overhaul button is not pressed, and the TCMS feeds back the train static test successfully.

After the train meets all the conditions in the dynamic test conditions, the VOBC applies for train dynamic test authorization to the control center OCC, after the authorization is obtained, the VOBC initiates a dynamic test instruction to perform dynamic test, and feeds back the dynamic test condition to the VOBC, and the VOBC feeds back the test result to the OCC.

Optionally, referring to fig. 3, fig. 3 is a flowchart illustrating sub-steps of step S14 according to an embodiment of the present disclosure. In the present embodiment, step S14 includes:

step S141, after obtaining the authorization, the VOBC sends a dynamic test valid signal to the TCMS, and initiates a cab selection command to the cab.

And step S142, judging whether the activation information fed back by the selected cab is received.

Step S143, if the VOBC does not receive the activation information fed back by the selected cab, the VOBC sends the information of the automatic wakeup failure.

And step S144, if the VOBC receives the activation information fed back by the selected cab, the VOBC sends a dynamic test instruction to the TCMS of the cab activated by the train.

In the above steps, the train usually includes two cabs, a front cab and a rear cab, and when performing dynamic testing, the cabs at the front and rear of the train need to be dynamically tested respectively. Thus, after obtaining authorization, the VOBC first sends a dynamic test valid signal to the TCMS and initiates cab selection commands to the cab in a preset sequence.

For example, a cab selection command is initiated to the cab of the locomotive, if activation feedback information of the cab of the locomotive is received, it is indicated that the cab is activated, and a subsequent dynamic test can be performed, otherwise, the cab is not activated, and the subsequent dynamic test cannot be performed, and at this time, the VOBC needs to send information of automatic wakeup failure to the OCC, and departure is not allowed.

When the cab is activated, the VOBC can output UTO signal hard lines, direction instructions and other dynamic test instructions to the cab end activated by the train, and then various tests are completed.

After the driver's cab at the head end of the train completes the dynamic test, the driver's cab selection command can be continuously sent to the driver's cab at the tail end of the train, and the steps are repeated until the driver's cab at the tail end of the train completes each dynamic test.

Optionally, in this embodiment, the head and the tail of the train are only a relative concept to indicate two ends of the train, and in practical applications, the two ends of the train may be the head or the tail of the train, which is not specifically limited herein.

In the above steps, the jump test result may also be sent to the OCC, when the dynamic test is performed on the train, the jump test needs to be performed on the head car and the tail car of the train in sequence according to a preset sequence, if the jump test on the head car fails, the reason for the dynamic test failure and failure (the jump test on the head car) is directly fed back to the OCC, if the jump test on the head car succeeds, the jump test on the tail car is performed, if the jump test on the tail car succeeds, the dynamic test success is fed back to the OCC, and if the jump test on the tail car fails, the reason for the dynamic test failure and failure (the jump test on the tail car) is fed back to the OCC.

Further, in this embodiment, in step S151, performing a jump test on the head train of the train includes:

the TCMS of the head vehicle carries out jump test on the head vehicle according to a jump instruction sent by the VOBC of the head vehicle; judging whether the jump test of the head car is successful or not, wherein the jump test comprises a forward jump test or a backward jump test; if the forward jump test or the backward jump test is unsuccessful, judging that the head vehicle jump test fails; and if the forward jump test and the backward jump test are successful, judging that the head car jump test is successful.

In the above steps, when the skip test is performed on the head car, the TCMS of the head car receives the skip instruction sent by the VOBC of the head car, and performs the skip test on the head car according to the skip instruction, where the skip test includes a forward skip test and a backward skip test, and when both the forward skip test and the backward skip test of the head car are successful, the skip test of the head car is successful, and otherwise, the skip test of the head car is failed.

the TCMS of the head car receives a whistle instruction sent by the VOBC of the head car and controls the whistle of the head car through hard line output DO; the TCMS of the head car receives a jump instruction sent by the VOBC of the head car, and forwards the jump instruction to a traction system TCU and a brake system BCU through a network communication bus; the TCMS of the head vehicle receives a target jump distance, a traction level and a brake level sent by the VOBC of the head vehicle; the TCMS of the head car forwards the traction level to the TCU and forwards the brake level to the BCU; and controlling the train to run and stop through the traction level and the braking level. Calculating the actual running distance of the train; judging whether the actual running distance is within a preset error range of the target jump distance; if so, judging that the jump test of the head vehicle is successful; if not, the skip test of the head car is judged to fail.

In the above steps, taking forward skip test of the head car as an example, the TCMS of the head car receives a whistle instruction sent by the VOBC of the head car, and outputs DO control to the whistle of the head car through a hard line, the VOBC first outputs the forward instruction to the forward train line through the hard line, the TCMS monitors the state of the forward train line and the backward train line through DI input of the hard line to judge the comprehensive direction of the train, then the TCMS of the head car receives a skip instruction sent by the VOBC of the head car, and sends the forward instruction and the skip instruction to the TCU and the BCU through a network communication bus, the tcc further outputs a traction instruction or a brake instruction to the traction or brake train line through the hard line, the TCU and the BCU monitor the state of the traction and brake train lines, the TCMS of the head car further receives a target skip distance, a traction level and a brake level sent by the VOBC of the head car, and forwards the traction level to the TCMS, and the brake level to the BCU, and the brake level of the train, and the traction level and the brake level of the train are controlled according to the running state, the traction level and the stop of the train. And then the TCMS calculates the actual forward running distance of the train, judges whether the actual forward running distance is within the error range (for example, within +/-20 cm) of the target jump distance, if so, the test of the forward jump of the head train is successful, otherwise, the forward jump fails.

It is worth to be noted that the backward jump test flow of the head car is the same as the forward jump test of the head car, and the jump test of the tail car is only carried out when the forward jump test and the backward jump test of the head car are both successful.
