It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In order to facilitate understanding of the present embodiment, first, a train testing method disclosed in the embodiments of the present application is described in detail, where an execution main body of the train testing method provided in the embodiments of the present application is generally a computer device with certain computing capability, and the computer device includes, for example: a terminal device, which may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle mounted device, a wearable device, or a server or other processing device. In some possible implementations, the method for testing a train may be implemented by a processor calling computer readable instructions stored in a memory.
The following describes a train testing method provided in an embodiment of the present application, taking an execution subject as a terminal device as an example.
Referring to fig. 1, a flowchart of a test method for a train provided in an embodiment of the present application is shown, where the test method includes steps S101 to S103, where:
s101: controlling a brake module of a train to be tested to apply a braking force to the train to be tested;
s102: after determining that the braking force is successfully applied, controlling a traction module of the train to be tested to apply traction to the train to be tested, and obtaining a traction application result; wherein the traction forces have different directions and values;
s103: and determining a traction test result of a traction module in the train to be tested based on the traction application result, and determining a brake test result of a brake module in the train to be tested based on the test state of the train to be tested in the test process.
According to the embodiment of the application, the system joint test is completed by utilizing the matching of the braking test and the traction test, so that the braking test and the traction test are completed on the premise that the train does not move, and the test efficiency of the train is improved.
The following describes each of the above-mentioned steps S101 to S103 in detail.
Firstly, in the above S101, the signal control center of the train to be tested may send a service brake application command to the train through a normal train control manner to apply a braking force to the train to be tested, and generally, the brake application command is a 100% brake application command to test the brake system.
In an embodiment of the application, before controlling a brake module of a train to be tested to apply a braking force to the train to be tested, the testing method further includes:
controlling the parking brake module of the train to be tested to apply parking brake force to the train to be tested, and detecting parking brake application state information of the parking brake module of the train to be tested in the test process; the parking brake applying state information comprises a parking brake applying state signal and the circulation time of the parking brake applying state signal;
determining whether the parking brake module is normally operated based on the parking brake application state information;
if the parking brake module does not normally operate, the current testing process is terminated, and the parking brake module of the train to be tested is determined to have a fault.
For example, to ensure the safety of the test process, the parking brake system of the train to be tested needs to be tested. In a fully automatic operation system, the train is generally specified in the operating regulations to be in a parking brake application state before waking up. Specifically, the signal control center sends a parking applying instruction to the train in a hard wire mode; the train collects the state of a parking brake pressure switch in an Input/Output (I/O) mode, and feeds back a parking application test result to a signal control center in a multifunctional train Bus (MVB) mode. Among them, the multifunction train bus is a serial data communication bus mainly used between interconnection devices having requirements for interoperability and interchangeability. Correspondingly, in the embodiment of the application, a parking mitigation test can be further included, and specifically, the signal control center sends a mitigation instruction of parking to the train in a hard-wire mode; the train collects the state of a parking brake pressure switch through network I/O, and feeds back a parking release test result to a signal control center through an MVB mode or an Ethernet.
In the embodiment of the application, in order to ensure that the test can be performed safely and smoothly, the brake system needs to be tested. Specifically, after the train is powered on, the air compressor is started, and generally, after the air pressure is greater than 7.5Bar, the braking system can smoothly complete self-checking and tests of various brake application and release, which is a basic premise of subsequent tests. The brake system carries out self-checking on the conventional performance of the system, and the signal system judges that the system fails when the self-checking fails or the feedback is overtime.
After the parking brake system and the brake system are determined to be normal, the signal control center can send a common 100% brake application instruction to the train in a normal train control mode, and apply braking force to the train to be tested.
In an embodiment of the present application, a method of determining success of application of the braking force includes:
acquiring brake application state information of the brake module in a test process; the brake application state information comprises a brake application state signal and the circulation time of the brake application state signal;
judging whether the braking force is applied successfully or not based on the brake application state information;
and if the braking force is not applied successfully, terminating the current test process.
For example, the brake System sends the single-frame 100% service brake application state to a Train Control and Management System (TCMS) through a network, and the Train TCMS sends the service application test result to the signal Control center through the test port after integration. And (4) receiving a feedback signal and feedback time of the application state of the 100% service brake sent by the train TCMS, and judging whether the test is successful or failed.
Secondly, in the above S102, after determining that the application of the braking force is successful, the traction module of the train to be tested can be controlled to apply the traction force to the train to be tested.
Generally, in order to realize reliable operation of a train, the subway train can be subjected to maintenance work of different levels such as daily maintenance, monthly maintenance, fixed maintenance, rack maintenance, overhaul and the like according to regulations after the train returns to a warehouse. In daily maintenance, part of non-fully-automatic driving trains can be subjected to system test on the traction and braking performance of the trains manually according to the manual motor cars aiming at the traction and braking system, the fully-automatic driving trains are controlled by a control center in a dynamic test mode at present without manual participation, and the traction and braking system is tested by controlling the front and back jumping of the two ends of the trains respectively. With the increase of the technical development and the operation experience of the full-automatic operation system, the train can test and guarantee traction braking and the whole system by properly optimizing the static test content of the train traction braking system in the operation period under the condition of effectively finishing the monthly overhaul and the fixed repair of the train according to the regulations.
Specifically, the test of the traction braking system in the automatic wake-up process of the full-automatic driving train is divided into a self-checking part and a dynamic test part. And finishing equipment self-checking of each system in the static test process of the train, wherein the train which is finished by self-checking has a traction braking dynamic test condition. The detection of the traction brake system is mainly focused on the dynamic test process. After the static test of the train is finished, a vehicle-mounted Controller (VOBC) sends a dynamic test authorization application to a Zone Controller (ZC), and after the VOBC receives dynamic test authorization information returned by the ZC, the VOBC controls the train to jump, so that the train finishes the long jump in the direction far away from the garage door and the direction close to the garage door, and then is switched to the other driving end of the train to repeatedly jump. And the VOBC outputs traction with preset duration and preset size to the train, and when the train runs at zero speed, the VOBC outputs a jump completion mark. And if the jumping result is normal, the dynamic test of the driving end is passed. Therefore, reliable work of the traction system and the braking system of the train to be tested is realized.
However, the above methods have certain disadvantages, including: in order to meet the requirement of completing dynamic testing when a dormant train is awakened, the parking train inspection line, the weekly and monthly inspection line and the drawing line need to be lengthened, and the length of each double-train inspection position needs to be increased by at least 15 meters, so that the floor area of a train section is greatly increased, and the construction cost is increased; the dynamic test consumes a long time when the train is awakened, each end takes about 3 minutes, and both ends take 6 minutes, so that the operation efficiency is influenced. When the train moves at an unexpected position in the dormancy stage, the unexpected collision between the train and an adjacent train or a building is easily caused in the dynamic test process of the train when the train is awakened according to the memorized position; each train needs to carry out bidirectional jump dynamic test, and the energy consumption and equipment loss of the train are increased in the test process.
In order to solve the problems, the dynamic test is cancelled, and the system joint test is completed by matching the brake test and the traction test. Normally, when applying braking, it is not possible to issue a traction command for applying traction. In order to solve the problem, before traction test is carried out in a common brake application state, a signal control center and a TCMS are matched together to complete the brake non-release software bypass, so that a traction inverter can normally output traction current, and after the traction test is completed, the brake non-release software bypass is cancelled.
In an embodiment of the present application, before controlling a traction module of the train to be tested to apply traction to the train to be tested, the testing method further includes:
acquiring a self-checking feedback signal of a traction module;
determining a self-checking result based on the self-checking feedback signal and the feedback time of the self-checking feedback signal;
and if the self-checking result shows that the fault exists, terminating the test process.
Illustratively, the signal control center sends a braking self-test instruction to the train TCMS through the network, waits for the train TCMS to feed back a self-test result or judge overtime, and sends a static test result of the traction system to the vehicle-mounted VOBC by detecting fault feedback of the traction system.
In addition, in the embodiment of the present application, a direction instruction test should be further included, specifically, the signal control center sends forward and backward instructions with the current activation end as a forward direction, respectively. The TCMS feeds back the direction instruction receiving state to the signal control center.
Thirdly, in the above S103, after applying the brake and the traction to the train to be tested, the corresponding test information is obtained, and the final test result can be determined based on the information.
For a traction test result, the traction application result comprises a traction current generated by the traction module during the test;
the determining a traction test result of a traction module in the train to be tested based on the traction application result comprises the following steps:
acquiring a traction current value generated by the traction module in a test process, and judging whether the traction current value meets a preset current value interval corresponding to the traction force or not based on different traction forces;
and if so, determining that the traction module normally operates.
Aiming at the brake test result, the test state of the train to be tested in the test process comprises whether the train to be tested moves or not;
the determining the brake test result of the brake module in the train to be tested based on the test state of the train to be tested in the test process comprises the following steps:
if the train to be tested does not move in the testing process, determining that the brake module normally operates;
and if the train to be tested moves in the testing process, determining that the brake module has a fault, and controlling the brake module to apply parking brake force to the train to be tested.
Illustratively, since during the traction test, if 100% service braking is in order, the normal output of traction does not cause movement of the train. If the train moves unexpectedly, the signal control center applies parking brake to the train. Specifically, the signal control center sends a direction instruction and a short-time 10% level traction application instruction to the train in a normal train control mode. The traction inverter generates traction current and reports the traction current to the signal system through the TCMS, and in the test process, the train applies 100% braking state to ensure that the train can not actually move. If the movement occurs, the signal should immediately apply parking brake to the train and alarm. Correspondingly, the signal control center sends a direction instruction and a short-time 75% level traction application instruction to the train in a normal train control mode. The traction inverter generates traction current and reports the traction current to the signal control center through the TCMS, and in the test process, the train applies 100% braking state to ensure that the train can not actually move. If the movement occurs, the signal should immediately apply parking brake to the train and alarm. In the whole test process of the traction system, the train applies 100% brake, and the state and the performance of the traction equipment of the train are tested to meet the requirements. The existing dynamic test of awakening is replaced by a combined mode of testing the brake system and testing the traction system, the requirement that the train does not need the motor car to realize the dynamic test is met, and the mode that the existing motor car jumps to realize the dynamic test is replaced.
Because the train does not move, the testing distance can be shortened, the construction land is saved, and the detection time is shortened. Because the train does not run, the cost can be reduced, the energy consumption and the equipment loss are saved, and the transformation of a non-full-automatic driving line is facilitated.
In the embodiment of the application, the test items in the test items of the traction brake system can be properly adjusted according to different specific product models and characteristics. The sequence of the traction test and the brake test in the traction brake system test project can be optimized and adjusted according to different products. The pull level may also be adjusted.
In the embodiment of the present application, in addition to testing the application of braking force, the method further includes: and controlling the brake module of the train to be tested to stop applying the braking force to the train to be tested, and acquiring a brake release test result corresponding to the brake release test based on the brake release test for stopping applying the braking force.
Illustratively, the signal control center sends a service brake release instruction to the train in a normal train control mode, namely, a hard wire does not output a brake effective instruction, meanwhile, the signal control center disconnects a brake maintaining output contact, when the train TCMS receives a service brake release test instruction sent by the signal control center through the MVB, the train TCMS sends a brake maintaining release instruction, and the brake system releases the brake maintaining. And the train TCMS judges the state of a relay of the brake release ring and feeds back a common release test result to the signal control center.
In this embodiment of the application, in order to ensure the safety of the whole testing process, after the brake module controlling the train to be tested stops applying the braking force to the train to be tested, the testing method further includes: and controlling a parking brake module of the train to be tested to apply parking brake force to the train to be tested.
In addition, in the embodiment of the application, because the dynamic test is cancelled, the dynamic test has the advantage of complete whole-system test of the motor train aiming at an unmanned system, and aiming at the blind spot, the embodiment of the application starts from the interior of the train and can accurately make final system guarantee confirmation when the rail is switched and parked. In this application, the operational requirements of the train when the switch rail is parked are not taken as part of the wake-up, but if the train cannot normally move and park, the fault can be fully exposed in the process. If the vehicle can be stopped accurately, the number of the vehicle can be issued and received according to the plan, and if the vehicle cannot be stopped, the vehicle can be alarmed and fed back. Namely, the train is adjusted to be stopped before leaving the warehouse according to the operation rule setting. If the train can not accurately stop at the first stop, the system can give an alarm in time and quit the operation and return to the warehouse for maintenance when the train is serious.
In the embodiment of the application, after the test is finished, the vehicle-mounted VOBC triggers the train to change the end, the test is repeated after the end is changed, and under the condition that the tests on both ends are finished, the train is considered to be awakened successfully in a remote mode.
In addition, in this embodiment of the present application, the test method further includes: and after receiving an emergency brake application command, controlling an emergency brake module of the train to be tested to apply emergency brake force to the train to be tested.
