Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the application provides a method for testing the temporary speed limit received in a novel train control system complete mode, as shown in fig. 1, and the following specific steps are provided for the embodiment of the application:
101. setting up a simulation test environment for executing the test, wherein the layout in the simulation test environment at least comprises: the system comprises vehicle-mounted equipment, a human-computer interface unit (Driver-Machine Interface, DMI), a Radio Block Center (RBC), a positioning simulation device, a train tail simulation device, a temporary speed limiting server and a trackside simulation device.
In the embodiment of the application, in order to realize the simulation test of temporary speed limit, a simulation test environment is built in advance, and a structural schematic diagram of a novel train control system is shown in fig. 2. The on-board devices (e.g., train overspeed protection device (Automatic Train Protection, ATP)) and DMI devices as shown in fig. 2 are real devices; RBC, global satellite navigation system (Global Navigation Satellite System, GNSS), tail-of-line (EOT), temporary speed limit server (Temporary Speed Restriction Server, TSRS), and trackside are simulation devices. Specific applications of the simulated test environment are explained below in connection with steps 102-105.
102. And providing a transponder arranged on the simulated track line in a simulation test environment based on cooperation of the temporary speed limiting server, the trackside simulation device and the positioning simulation device.
In the embodiment of the application, an electronic map is pre-imported in the temporary speed limiting server, the electronic map comprises virtual transponder data which are distributed, and the pre-imported physical transponder data are in the trackside simulation equipment. It should be noted that, many physical transponders and virtual transponders are also distributed on the real railway, so that the following functions are achieved: for complex road conditions on railways, the difficulty of installing entity transponders in some places is high, and virtual transponders can be used for replacing the entity transponders; or because the distance between the two entity transponders is relatively far, the effective positioning of the train is not facilitated, and virtual transponders can be additionally arranged between the two entity transponders so as to reduce the distance between the transponders.
In the technical field of rail transit, the transponder is mainly used for positioning, but the transponder alone is not safe enough, so that positioning simulation equipment (such as GNSS simulation equipment) is adopted to achieve the purpose of positioning correction in the embodiment of the application. For example, when there is satellite positioning, the virtual transponder is only active and the train passes the virtual transponder and receives the message from the virtual transponder.
Above, according to this, the embodiment of the application adopts interim speed limit server, the pararail emulation equipment and location emulation equipment collaborative work, provides the transponder of laying on the simulation track circuit under simulation test environment.
103. And in the process of running the train on the simulated track line, controlling the RBC to send a temporary speed limiting message to the vehicle-mounted equipment when the train is switched into a full mode.
In a real running scene of the train, after RBC generates a running license and sends the running license to the vehicle-mounted equipment, the train is transferred into a complete mode after RBC authorization to run the train in a corresponding control area is obtained. After the train is switched into the complete mode, when the condition of the road in front of the running of the train is complex, for example, when the train passes through a road which is not suitable for high-speed sports cars, such as a bridge tunnel, the RBC can send a temporary speed limiting message to the vehicle-mounted equipment, so that the running speed of the train is reduced, and the running safety is ensured.
In the embodiment of the application, when the RBC starts to send the temporary speed limit message to the vehicle-mounted equipment as a test time starting point, relevant test operation of receiving the temporary speed limit is executed.
104. And calculating and generating a target MRSP curve by using vehicle-mounted equipment according to the temporary speed limit message and the allowable speed determined by the driving permission of the train, and outputting and displaying by using the DMI equipment.
Wherein a most restrictive speed profile (Most Restrictive Speed Profile, MRSP) is displayed on the DMI device, and the MRSP profile is displayed as a relationship between train operation "speed and distance".
For example, an MRSP curve illustrated in the embodiment of the present application is shown in fig. 3, and in fig. 3 (a), an MRSP curve in which an provisional speed limit message is not received is shown, wherein the abscissa represents a distance of a train operation and the ordinate represents "maximum allowable speed of train operation (SSP) determined based on a driving license", whereby a relationship between "speed and distance" is indicated according to the abscissa.
However, after receiving the temporary speed limit message, the vehicle-mounted device recalculates the MRSP curve, assuming that the temporary speed limit interval determined by the temporary speed limit message is D1 to D2 and the temporary speed limit value is "V", and "V" is smaller than "SSP", and after receiving the temporary speed limit message, the MRSP curve as shown in (b) of fig. 3 is recalculated.
It should be noted that, for the sake of brevity and clarity of showing the "whether a temporary speed limit message is received or not" the embodiment of the present application only uses fig. 3 to schematically illustrate the MRSP curve, and those skilled in the art should know that the curvature and the change of the curve are also complex, and the details of the MRSP curve are not described in detail in the embodiment of the present application.
105. Based on the position relation between the temporary speed limit section and the transponder determined by the temporary speed limit message, monitoring whether the target MRSP curve is abnormally changed which does not accord with the temporary speed limit or not in the process that the train runs to the temporary speed limit section until the train leaves, so as to complete the test of receiving the temporary speed limit in the complete mode.
The train runs at the allowable speed V of the temporary speed limit zone, and the target MRSP curve is abnormal which does not accord with the temporary speed limit in two cases: the rate limit of the MRSP curve decreases and the rate limit of the MRSP curve increases. When the speed limit of the MRSP curve is reduced, the running speed of the train exceeds the maximum running speed allowed by the MRSP curve, so that overspeed is caused, and the DMI equipment can emit dripping sound to give an alarm prompt.
When the speed limit of the MRSP curve is increased, the running speed of the train is lower than the maximum running speed allowed by the MRSP curve, and a round speed dial on the DMI equipment can display the current running speed and the allowed speed for a certain interval, so that the MRSP curve is abnormal.
And the embodiment of the application also exemplifies an exemplary implementation method for calculating the change of the train speed in the process that the train runs through the temporary speed limit zone, and the method comprises the following steps:
the temporary speed limiting messages sent by the RBC to the vehicle-mounted equipment are all sent based on the transponder, and if the current transponder through which the train passes is transponder A, the temporary speed limiting messages sent by the RBC mainly comprise the following information:
d_lrbg (unit: meters): the distance from the transponder A to the starting point of the front temporary speed limit section;
l_lrbg (unit: meters): the length of the temporary speed limiting section is D_lrbg;
V (unit km/h): the speed of the temporary speed limit section, namely the speed limit of the section taking D_lrbg as a starting point and L_lrbg as a section.
In the full mode, the speed of the vehicle-mounted current operation, namely the initial speed SSP, is known, the acceleration a of the train operation can be read from an acceleration module (wherein the acceleration module can calculate the acceleration according to the initial speed and the final speed), and the following formula (1) is adopted according to a speed displacement formula:
SSP 2 -V 0 2 =2as formula (1);
the displacement s and the current running speed V of the train can be obtained 0 The relation is then that the allowable speed during the train operation is:
interval [ D_lrbg-s, D_lrbg]The allowable speed between is V 0 ；
The allowable speed between the intervals [ D_lrbg, D_lrbg+L_lrbg ] is V;
interval [ D_lrbg+L_lrbg, D_lrbg+L_lrbg+s ]]The allowable speed between is V 0 。
In the embodiment of the present application, the target MRSP curve calculated in step 104 is generated by immediately executing the calculation operation when the temporary speed limit message is received, but the train does not actually run to the corresponding temporary speed limit zone, and the test in the embodiment of the present application aims at verifying whether the temporary speed limit function is reliable and stable in the complete mode of the novel train control system if the target MRSP is abnormal and not conforming to the temporary speed limit when the temporary speed limit zone passes.
In the test process, in order to prevent the occurrence of the condition that the running speed of the train is suddenly raised due to the fact that the temporary speed limiting information is deleted after the train passes through the transponder, the test scheme designed by the embodiment of the application is that a plurality of constraint conditions for testing are added based on the position relation between the temporary speed limiting area and the transponder, which is determined by the temporary speed limiting information.
Illustratively, various constraints for the test are added, such as: 1. the end point of the temporary speed limit zone is far away and does not reach the position of the transponder yet; 2. the temporary speed limit area covers the position of the transponder; 3. the start of the temporary speed limit interval exceeds and is far from the location of the transponder but does not reach the location of the next transponder. And (3) the constraint conditions are that whether the target MRSP curve is abnormally changed which does not accord with the temporary speed limit or not is tested in the process that the train runs to the temporary speed limit zone until the train leaves.
If abnormal changes, such as sudden rising, occur, the temporary speed limiting control function in the complete mode of the novel train control system is indicated to be defective, and related abnormalities should be timely alarmed or prompted to be reported to research and development personnel for debugging.
Above, the embodiment of the application provides a test method for receiving temporary speed limit in a novel train control system complete mode, and the embodiment of the application pre-builds a simulation test environment for executing test, and the layout at least comprises: the system comprises vehicle-mounted equipment, DMI equipment, RBC, positioning simulation equipment, train tail simulation equipment, a temporary speed limiting server and trackside simulation equipment; under the simulation test environment, the train running condition can be simulated to realize the issuing of temporary speed limiting information to the vehicle-mounted equipment, so that the vehicle-mounted equipment is utilized to calculate and generate a corresponding target MRSP curve, and a plurality of transponders arranged on the simulated track line are also provided under the simulation test environment; therefore, based on the position relation between the temporary speed limit section and the transponder determined by the temporary speed limit information, whether the target MRSP curve is abnormally changed which does not accord with the temporary speed limit or not is monitored in the process that the train runs to the temporary speed limit section until the train leaves, so that the test of receiving the temporary speed limit in the complete mode is completed. Compared with the prior art, the embodiment of the application provides an effective test scheme for realizing temporary speed limit of receiving in a complete mode by using the built simulation test environment.
Further, for more detailed explanation, the embodiment of the present application further provides another testing method for receiving temporary speed limit in the full mode of the novel train control system, as shown in fig. 4, and the following specific steps are provided for this embodiment of the present application:
201. setting up a simulation test environment for executing the test, wherein the layout in the simulation test environment at least comprises: the system comprises vehicle-mounted equipment, DMI equipment, RBC, positioning simulation equipment, train tail simulation equipment, a temporary speed limiting server and trackside simulation equipment.
202. And providing a transponder arranged on the simulated track line in a simulation test environment based on cooperation of the temporary speed limiting server, the trackside simulation device and the positioning simulation device.
203. And in the process of running the train on the simulated track line, controlling the RBC to send a temporary speed limiting message to the vehicle-mounted equipment when the train is switched into a full mode.
In the embodiment of the present application, the explanation of steps 201 to 203 is referred to steps 101 to 103, and will not be repeated here.
204. And calculating and generating a target MRSP curve by using vehicle-mounted equipment according to the temporary speed limit message and the allowable speed determined by the driving permission of the train, and outputting and displaying by using the DMI equipment.
For the test of temporary speed limit in the complete mode of the novel train control system, the embodiment of the application firstly generates an MRSP curve based on the allowable speed determined by the driving license, and then recalculates and generates a target MRSP curve based on the received temporary speed limit message.
The embodiment of the application fully considers two different situations that one temporary speed limiting message or a plurality of temporary speed limiting messages are received at the same moment, and correspondingly provides the following two schemes for generating the target MRSP curve, which are specifically as follows:
one scheme is: and when a temporary speed limit message is received at the same moment, namely the temporary speed limit message issued by the RBC to the vehicle-mounted equipment is one, re-calculating and generating a new target MRSP curve on the basis of the MRSP curve generated without receiving the temporary speed limit message before according to the temporary speed limit interval and the temporary speed limit determined by the temporary speed limit message. MRSP curves shown in each of (a) and (b) in fig. 3 as exemplified in the examples of the present application.
The other scheme is as follows: and when a plurality of temporary speed limiting messages are received at the same moment, namely, when the number of temporary speed limiting messages issued by RBC to the vehicle-mounted equipment is multiple, performing superposition processing on each temporary speed limiting message to obtain a target temporary speed limiting section and a target temporary speed limiting executed on the target temporary speed limiting section, and according to the target temporary speed limiting section and the target temporary speed limiting, recalculating and generating a new target MRSP curve on the basis of a curve generated by the fact that the temporary speed limiting messages are not received before.
In the following, the embodiment of the present application uses two temporary speed limit messages received at the same time as an illustration, but it needs to be explained in advance, and for the case that more than two temporary speed limit messages are received at the same time, the adopted superposition processing principle is the same, that is, the superposition processing principle is equivalent to the combination processing to obtain a temporary speed limit data with a target temporary speed limit interval and a target temporary speed limit, so that the embodiment of the present application is not repeated in enumeration.
For example, for two temporary speed limiting messages received at the same time, denoted as TRS1 and TRS2, assuming that the speed limiting start point of TSR1 is D1, the speed limiting end point is D2, and the speed limiting value is V1, the speed limiting start point of TSR2 is D3, the speed limiting end point is D4, and the speed limiting value is V2, and the allowable speed determined by the train driving license is SSP, the following 12 test scenarios will be obtained by performing the superposition processing on the two temporary speed limiting messages on the premise that the positional relationship with the transponder is temporarily not considered:
example 1: if TSR1 and TSR2 are non-overlapping, i.e., D1< D2< D3< D4, according to the three cases where V1> V2, v1=v2, and V1< V2 exist, 3 test scenarios will be obtained, and the target MRSP curve will be recalculated, as shown in fig. 5.
When V1> V2 in (a) of fig. 5, the target MRSP curve satisfies: the speed limit in the interval D1-D2 is V1, and the speed limit in the interval D3-D4 is V2. When v1=v2 in (b) of fig. 5, the target MRSP curve satisfies: the speed limit in the interval D1-D2 is V1, and the speed limit in the interval D3-D4 is V2. In fig. 5 (c), when V1< V2, the MRSP curve satisfies: the speed limit in the interval D1-D2 is V1, and the speed limit in the interval D3-D4 is V2.
Example 2: if TSR1 and TSR2 are connected end to end, i.e. d1< d2=d3 < D4, according to the three cases where V1> V2, v1=v2 and V1< V2 exist, 3 test scenarios will be obtained, and the target MRSP curve is recalculated, as shown in fig. 6.
When V1> V2 in (a) of fig. 6, the target MRSP curve satisfies: the speed limit in the interval D1-D2 is V1, and the speed limit in the interval D3-D4 is V2. When v1=v2 in (b) of fig. 6, the target MRSP curve satisfies: the speed limit in the interval D1-D4 is V1 (V2). In fig. 6 (c), when V1< V2, the target MRSP curve satisfies: the speed limit in the interval D1-D2 is V1, and the speed limit in the interval D3-D4 is V2.
Example 3: if TSR1 and TSR2 are overlapping regions, i.e., D1< D3< D2< D4, according to the three cases where V1> V2, v1=v2, and V1< V2 exist, 3 test scenarios will be obtained, and the target MRSP curve will be recalculated, as shown in fig. 7.
When V1> V2 in (a) of fig. 7, the target MRSP curve satisfies: the speed limit in the interval D1-D3 is V1, and the speed limit in the interval D3-D4 is V2. When v1=v2 in (b) of fig. 7, the target MRSP curve satisfies: the speed limit in the interval D1-D4 is V1 (V2). In fig. 7 (c), when V1< V2, the target MRSP curve satisfies: the speed limit in the interval D1-D2 is V1, and the speed limit in the interval D2-D4 is V2.
Example 4: if TSR1 contains TSR2, i.e., D1< D3< D4< D2, 3 test scenarios will be obtained according to three cases of V1> V2, v1=v2, and V1< V2, and the target MRSP curve will be recalculated, as shown in fig. 8.
When V1> V2 in (a) of fig. 8, the target MRSP curve satisfies: the speed limit in the D1-D3 interval is V1, the speed limit in the D3-D4 interval is V2, and the speed limit in the D4-D2 interval is V1. When v1=v2 in (b) of fig. 8, the MRSP curve satisfies: the speed limit in the interval D1-D2 is V1 (V2). In fig. 8 (c), when V1< V2, the MRSP curve satisfies: the speed limit in the interval D1-D2 is V1.
It should be noted that, in the embodiment of the present application, based on the test scenarios determined based on the two schemes, constraint conditions of positions between the temporary speed limit interval and the transponder are added to expand, so as to obtain test contents with richer and more diversity in each test scenario, and the test method is applied to test the temporary speed limit function in the complete mode of the novel train control system. For any one test scenario, the constraint condition for increasing the position between the temporary speed limit interval and the transponder mainly comprises the following steps: 1. according to the running direction of the train, the speed limiting end point of the temporary speed limiting section is the position which does not reach the transponder; 2. covering the temporary speed limit area to the position of the transponder; 3. the start point of the temporary speed limit section exceeds and is far from the position of the transponder, but does not reach the position of the next transponder, according to the running direction of the train.
Based on this constraint, the test: and in the process that the train runs to the temporary speed limit section until the train leaves, monitoring whether the target MRSP curve recalculated based on the temporary speed limit message is abnormally changed which does not accord with the temporary speed limit, so that the purpose of one-time complete test is achieved. Based on such test requirements, the present embodiments employ at least 3 transponders in adjacent locations on the analog track line to complete one test.
In order to achieve comprehensiveness and accuracy of the temporary speed limiting function test, the embodiment of the application can further expand the test scheme to be as follows: a plurality of target transponder groups are formed based on the target transponders of optionally 3 adjacent locations from among the plurality of transponders laid out on the simulated track line, and a test for receiving the temporary speed limit in the full mode is repeatedly performed based on the plurality of target transponder groups. It should be noted here that optionally 3 transponders form the target transponder group, which is only exemplary, for example, alternatively more than 3 transponders may be selected, which is only necessary here for the purpose of performing the test operation in a plurality of iterations.
In the following, in order to avoid redundant explanation testing process, the embodiment of the present application takes receiving a temporary speed limiting message at the same time as an example, and optionally 3 transponders are grouped on a simulated track line, for example, a first transponder, a second transponder and a third transponder adjacently ordered according to a train driving direction, so as to construct a testing scenario, and the following testing process of steps 205-207 is provided, which is specifically explained as follows:
205. And at a preset distance before the train reaches the position of the first transponder, issuing a first temporary speed limiting message to the vehicle-mounted equipment by utilizing the RBC, and executing a test process.
(here, in the embodiment of the present application, in order to distinguish the temporary speed limit messages issued in the steps 205, 206 and 207 respectively, the identifiers "first", "second" and "third" are used for reference), and a test procedure is performed.
And at a preset distance before the train reaches the position of the first transponder, issuing a first temporary speed limit message to the vehicle-mounted equipment by utilizing the RBC, wherein the first temporary speed limit message determines a first temporary speed limit zone, and the speed limit end point of the first temporary speed limit zone is the position which does not reach the first transponder. Accordingly, the vehicle-mounted device recalculates the target MRSP curve based on the first temporary speed limit message (temporary speed limit section and speed limit value) and the allowable speed determined by the previous train driving permission.
For example, assuming that the allowable speed determined by the driving license is SSP, the temporary speed limit section determined by the first temporary speed limit message is D1 to D2 and the temporary speed limit is V (V < SSP), and the first transponder is identified as "transponder B", the target MRSP curve is recalculated as shown in (a) of fig. 9.
The whole test process is as follows: and monitoring whether the target MRSP curve obtained based on the first temporary speed limit message is abnormally changed which does not accord with the temporary speed limit or not in the process of running the train to the first temporary speed limit zone until the train leaves.
206. After the train runs past the location of the first transponder, a second temporary speed limit message is issued to the vehicle device using the RBC, and a testing procedure is performed.
After the train runs through the position of the first transponder, a second temporary speed limit message is issued to the vehicle-mounted device by utilizing the RBC, the second temporary speed limit message determines a second temporary speed limit zone, and the second temporary speed limit zone covers the position of the second transponder. Accordingly, the vehicle-mounted device recalculates the target MRSP curve based on the second temporary speed limit message (temporary speed limit section and speed limit value) and the allowable speed determined by the previous train driving permission.
For example, assuming that the allowable speed determined by the driving license is SSP, the temporary speed limit section determined by the second temporary speed limit message is D1 to D2 and the temporary speed limit is V (V < SSP), and the second transponder is identified as "transponder C", the target MRSP curve is recalculated as shown in (b) of fig. 9.
The whole test process is as follows: and monitoring whether the target MRSP curve obtained based on the second temporary speed limit message is abnormally changed which does not accord with the temporary speed limit or not in the process of running the train to the second temporary speed limit section until the train leaves.
207. And before the train runs through the second temporary speed limit zone but does not reach the position of the third transponder, issuing a third temporary speed limit message to the vehicle-mounted equipment by utilizing the RBC, and executing a test process.
Before the train runs through the second temporary speed limit section but does not reach the position of the third transponder, a third temporary speed limit message is issued to the vehicle-mounted device by utilizing the RBC, the third temporary speed limit section is determined by the third temporary speed limit message, and the speed limit starting point of the third temporary speed limit section is the position exceeding and far from the third transponder and does not reach the position of the next transponder. Accordingly, the in-vehicle apparatus recalculates the target MRSP curve based on the third temporary speed limit message (temporary speed limit section and speed limit value) and the allowable speed determined by the previous train running permission.
For example, assuming that the allowable speed determined by the driving license is SSP, the temporary speed limit section determined by the third temporary speed limit message is D1 to D2 and the temporary speed limit is V (V < SSP), and the third transponder is identified as "transponder D", the target MRSP curve is recalculated as shown in (c) of fig. 9.
The whole test process is as follows: and monitoring whether the target MRSP curve obtained based on the third temporary speed limit message is abnormally changed which does not accord with the temporary speed limit or not in the process of running the train to the third temporary speed limit zone until the train leaves.
