[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Figure 1FIG. 1 is a flow chart of a double-ended train testing method described in an embodiment of the present invention. Figure 1 As shown, including:

[0035] Step S1, the double-end train test model selects an activation end device according to the cab activation change information of the first-end vehicle-mounted device and the cab activation state change information of the second-end vehicle-mounted device;

[0036] Step S2: adjusting the speed information of the first vehicle-mounted device and the speed information of the second vehicle-mounted device according to the selected activation terminal device.

[0037] Specifically, the first onboard device and the second onboard device described in the embodiment of the present invention respectively refer to ATP / ATO devices carried at both ends of the same double-ended train.

[0038] The cab activation change information described in the embodiment of the present invention is obtained by the vehicle-mounted device according to the conversion process of the cab activation state of the previous cycle and the cab activation state of the current cycle.

[0039] Since the on-board devices at both ends may output activation (or inactivation) at the same time, it is impossible to determine the activation end simply by the activation status of the current cycle. The main scenarios are:

[0040] 1) Misjudgment of vehicle head

[0041] When turning back, if the final end 1 is the front of the train before the turn-back, and the end 2 is the front of the train after the turn-back (new front of the train), but during the folding process, due to problems such as double-end ATP communication transmission and status synchronization, it takes time for end 1 to change from activated to inactivated and for end 2 to change from inactivated to activated. During this period, both ends may be activated at the same time. At this time, if only which end is activated in this cycle is determined, end 1 may be considered to be activated, which is a misjudgment.

[0042] 2) When the object under test undergoes a brief change and then recovers, its fault cannot be identified.

[0043] In case 1), if the second end is already a new locomotive, the first end briefly changes from inactive to active, and then immediately becomes inactive. In this case, due to the short time, the train model locomotive judges that there is a short error and then corrects it. From the final train operation results, the fault of the object under test cannot be identified. Therefore, the embodiment of the present invention proposes a solution to select the activation end device based on the situation of two cycles before and after a certain end.

[0044] When the double-end train test model receives the cab activation change information of one end vehicle-mounted device, which is in the inactive state in the previous cycle and in the active state in the current cycle, the end where the vehicle-mounted device is located is selected as the head of the train, that is, the activated end device.

[0045] There is another situation where the cab activation change information of the first-end on-board device and the cab activation status change information of the second-end on-board device both satisfy the condition that they were activated in the previous cycle and inactive in this cycle. At this time, the first-end on-board device and the second-end on-board device are both inactive, indicating that in the current section, the double-end train test model cannot select the active end device and is in a "no locomotive state". There are only two situations for the train to show to the outside, namely with a locomotive and without a locomotive. Through analysis, it is known that the end at the locomotive should be the end that "changes from inactive to active"; only when both ends are inactive at the same time can the train be considered to have no locomotive.

[0046] In addition, the ATP outputs at both ends may change from inactive to active at the same time, but this kind of failure rarely occurs in actual processes, and the model will give an alarm at this time.

[0047] The embodiment of the present invention jointly manages two on-board devices through a double-end train test model, which is convenient for management and effectively reduces consumption. When the on-board devices at both ends and the on-board devices at the first end and the second end meet the conditions for activating the end devices at the same time, the double-end train test model that jointly manages the two on-board devices can better coordinate this situation and ensure the smooth progress of the double-end train test.

[0048] Based on the above embodiment, the cab activation change information is specifically information on the conversion of the cab activation state of the previous cycle to the cab activation state of the current cycle.

[0049] The cycle described in the embodiment of the present invention refers to a working cycle of the test simulation process, which may refer to a double-ended train passing a preset distance or a preset time, which is a time period.

[0050] The previous cycle described in the embodiment of the present invention refers to the cycle before the current cycle.

[0051] Based on the above embodiment, the cab activation change information specifically includes: the previous cycle was inactive and the current cycle is inactive, the previous cycle was inactive and the current cycle is active, the previous cycle was active and the current cycle is active, or the previous cycle was active and the current cycle is inactive.

[0052] Specifically, if the previous cycle is inactive and the current cycle is inactive, then this indicates that the end is still inactive; if the previous cycle is inactive and the current cycle is active, then this indicates that the end has become active, that is, the end must be the locomotive. If the ATP fails and there is a "short change", since this method only judges the locomotive once when the "inactive to active" state switches, it will eventually be considered that the faulty end is the locomotive, and the abnormality can be directly identified from the train running direction; if the previous cycle is active and the current cycle is active, it means that the end must not be the active end, and it cannot be considered "no locomotive" at this time. It should be considered that the other end is also "inactive" at the same time before it can be considered "no locomotive"; if the previous cycle is active and the current cycle is active, it means that the end may be the active end or the inactive end. If it is detected that both ends may be inactive, then enter the next cycle, and try to select the active end device in the next cycle. At this time, the current cycle will become the previous cycle of the next cycle.

[0053] The embodiment of the present invention uses different cab activation change information to better select the activation end device, thereby ensuring the smooth progress of the double-end train test.

[0054] On the basis of the above embodiment, the step of selecting the activation end device according to the cab activation change information of the first end vehicle-mounted device and the cab activation state change information of the second end vehicle-mounted device in the double-end train test model specifically includes:

[0055] The double-end train test model uses the on-board device as the on-board device with preset cab activation change information as the activation end device;

[0056] The preset cab activation change information is that the last cycle was in an inactive state and the current cycle is in an active state.

[0057] The double-end train test model further includes the step of selecting an activation end device according to the cab activation change information of the first end vehicle-mounted device and the cab activation state change information of the second end vehicle-mounted device;

[0058] If the cab activation change information of the first-end vehicle-mounted device and the cab activation state change information of the second-end vehicle-mounted device are both preset cab activation change information, an alarm message is generated and the test ends.

[0059] Specifically, if the cab activation change information of the first-end vehicle-mounted device and the cab activation state change information of the second-end vehicle-mounted device are both preset cab activation change information, then it should be determined that the first-end vehicle-mounted device and the second-end vehicle-mounted device are both locomotives, but the train state cannot have both ends being locomotives, so it can be determined that the ATP output of the object under test is abnormal, and an alarm is given at this time to end the test. The embodiment of the present invention effectively ensures that the double-end train is simultaneously valid during the test process, and can also ensure that the train test proceeds smoothly.

[0060] On the basis of the above embodiment, after the step of selecting the activation end device according to the cab activation change information of the first end vehicle-mounted device and the cab activation state change information of the second end vehicle-mounted device, the method further includes:

[0061] Obtain the acceleration information of the activation end device, and determine the step distance of the activation end device in the current cycle by combining the dynamic model formula;

[0062] The train-to-ground communication module determines the position information of the double-end trains according to the stepping distance of the current cycle of the activated end device.

[0063] Specifically, the direction information of the push-up direction handle and the level information of the traction handle in the virtual driving console are obtained. In FAO mode, the ATP / ATO sends the direction information and level information to the train model; the train running direction is determined according to the direction information; according to the level information, the dynamic parameter table is checked, and the acceleration / deceleration is determined by considering factors such as slope; then the step distance of the cycle operation is calculated according to the dynamic model formula. The step distance message is sent to the vehicle-ground communication module for position calculation, specific track ID and offset, and sent to the operation diagram, which displays the train position in real time.

[0064] On the basis of the above embodiment, other vehicle control IO quantities such as the ATO mode are stored in two variables, with vehicle control related parameters provided at both ends respectively, and each variable is changed in a rising edge / falling edge manner to reduce the amount of calculation.

[0065] The embodiments of the present invention may be more conducive to the conduct and observation of the test by calculating the speed and position.

[0066] Figure 2 A simulation system framework diagram described in an embodiment of the present invention is shown in FIG. Figure 2As shown in the figure, the on-board equipment at both ends will send the cab activation change information to the train model through their respective on-board interface platforms and train agents, and the train model will also obtain speed information from the simulated driving console, and then send the speed information to the train agents at both ends respectively. The agents will send the speed to the corresponding on-board interface platforms and finally to ATP / ATO; the train-to-ground signal is used to receive the step distance of the current cycle, and determine the double-end train position according to the step distance of the current cycle, that is, the position of the front and rear of the double-end train, and then send the double-end train position to the operation diagram display.

[0067] Figure 3 This is a flow chart of the calculation of the kinetic model described in one embodiment of the present invention, such as Figure 3 As shown, first create a train, then create an instance process, then perform virtual driver operations (in FAO mode, cancel virtual driver operations, activate ATP output cab, and perform automatic driving by ATP / ATO), then calculate dynamic parameters: acceleration, speed and step displacement, send the calculated speed and step displacement to the vehicle-ground signal, perform position advancement, then calculate train position and other information, and finally display the train position in the operation diagram.

Figure 4 As shown, it includes: an activation end selection module 410 and a speed adjustment module 420; wherein the activation end selection module 410 is used for a double-end train test model to select an activation end device according to the cab activation change information of a first-end vehicle-mounted device and the cab activation state change information of a second-end vehicle-mounted device; wherein the speed adjustment module 420 is used to adjust the speed information of the first-end vehicle-mounted device and the speed information of the second-end vehicle-mounted device according to the selected activation end device.
