In order to describe the above embodiment in more detail, as shown in fig. 5, the embodiment of the present invention further details a specific implementation method for generating a test scenario in a tool, and the following specific steps are provided for the embodiment of the present invention:
201. and after receiving the station information input by the user, determining a target station to be tested.
In the embodiment of the invention, a user can input station information through a human-computer interaction interface of the tool, and the tool automatically determines the target station to be tested according to the station information.
202. And determining the active transponder installed in the target station by searching the transponder position table.
On the tool side, after a target station to be detected is determined, the information of an active transponder installed in the target station is acquired by searching a transponder position table pre-stored in an engineering data table, and the method at least comprises the following steps: active transponder type and active transponder location information.
203. And determining the route associated with the active transponder by searching the route information table to obtain the target scene information formed by the active transponder and the corresponding route.
On the tool side, according to the logical association relation among a plurality of data tables in the engineering data table, a plurality of routes associated with the searched active transponder are obtained by searching the route information table, and the active transponder and the corresponding route form target scene information.
It should be noted that, in the embodiment of the present invention, since the constructed test scenarios may also exist differently due to different routes and different types of active transponders, the target scenario information is constructed based on these two main factors. In addition, the test method according to the embodiment of the invention adopts a critical point test method, namely a series of speed limits from the lowest speed limit value to the highest speed limit value are issued in the interval of the fixed range of the inner side and the outer side of the critical point and the interval of the fixed range of the crossing critical point, and the critical points are selected to have difference for different target scene information.
204. And obtaining a target test critical point corresponding to the target scene information by searching a preset mapping relation between the pre-constructed scene information and the test critical point.
In the embodiment of the invention, in order to realize the automation of generating the test case side by using a tool, a preset mapping relation between scene information and a test critical point is constructed in advance, so that for each group of different scene information, the position of the critical point is not required to be calculated manually, but after the target scene information is determined in step 203, the preset mapping relation is called and the corresponding test critical point is found by using a pre-edited control program, so that the core key (namely, the test critical point) of the critical point test method is found by using automatic replacement manual processing.
205. And generating a test scene corresponding to the target scene information by using the target test critical point and preset parameter information, wherein the preset parameter information at least comprises preset speed limit value information.
Wherein, the preset parameter information comprises: the number of block partitions for each line from the highest code to the red-yellow code in the forward and reverse directions is related to the highest speed of the railway line allowed to run.
For example: and the highest code in the forward direction and the reverse direction of a certain line is the code L5, the number of the block partitions which are reduced from the highest code to the red-yellow code is 8(L5- > L4- > L3- > L2- > L- > LU- > U- > HU), and the number of the block partitions is related to the highest speed of the railway line allowed to operate. Wherein, the L code permits the train to run according to the regulated speed, the locomotive signal machine displays a green light; the LU code is that the train is permitted to operate according to the specified speed, and the locomotive signal displays a half green and half yellow light (only suitable for getting on station and getting off the train); the U code requires the train to pay attention to the operation, and the locomotive signal machine displays a yellow light; HU code requires timely taking parking measure, and the locomotive signal machine displays a half red and half yellow light. The track circuit encoding is referenced to a cab signal information definition and assignment criterion (TB/T3060).
The preset parameter information further includes: and setting a temporary speed limit value in the test case, wherein the temporary speed limit value is lower than the maximum speed allowed by the railway line, such as: positive line speed limit value: 45. 75, 80, 120, 200km/h. side line speed limit: 45. 80 km/h. These temporary speed limit values are speed limit values set at critical points, and thus the critical point test method is adopted in the embodiment of the present invention.
In the embodiment of the invention, the preset parameter information is input into the tool in advance according to the test requirement, and the number of the block subareas in the preset parameter information and the preset temporary speed limit are combined, so that the temporary speed limit is set in the railway range of the block subareas to construct the test scene.
Specifically, for the step 205, the test scenario refinement statement corresponding to the target scenario information generated by using the target test critical point and the preset parameter information is as follows:
firstly, selecting an inner preset threshold and an outer preset threshold of a target test critical point to obtain a temporary speed-limiting interval crossing the target test critical point and consisting of the inner preset threshold and the outer preset threshold.
In the embodiment of the present invention, the obtained route scenarios are different according to different target scenario information, so that the transponder jurisdiction ranges determined according to the information content recorded in the engineering data table are also different, and in the embodiment of the present invention, a target test critical point is selected from the transponder jurisdiction ranges, for example, a route scenario and the transponder jurisdiction range determined in the scenario are listed, as shown in fig. 6:
the train control center one-way temporary speed limit jurisdiction range is to increase a braking distance from the station entrance to the station exit (or the second active transponder group of the relay station) in front, and the braking distance covers all block partitions from the highest allowable code of the line to the HU code and extends for 100 m. For this jurisdiction, active transponder locations are selected as target test critical points.
In the embodiment of the invention, the corresponding obtained transponder management ranges are different in different access scenarios, and the temporary speed limit technical specifications are specifically found in a Q-CR 662 and 2018 train control system issued by a railway department.
The key point of the embodiment of the invention lies in how to specifically realize the adoption of the critical point test method, and the key point is to select the temporary speed limit interval, namely, select the inner preset threshold and the outer preset threshold of the target test critical point to obtain the temporary speed limit interval which crosses the target test critical point and consists of the inner preset threshold and the outer preset threshold.
For example: respectively selecting the range of 1 meter inside and the range of 1 meter outside the target test critical point, and obtaining the temporary speed limit intervals of 1 meter inside and outside ranges by crossing the target test critical point.
Secondly, according to the target scene information, determining the line direction, such as: and the line is forward or reverse, so that the speed limit starting point and the speed limit end point corresponding to the temporary speed limit section are determined according to the line direction.
And finally, forming a test scene corresponding to the target scene information according to the route, the speed limit starting point and the speed limit end point contained in the scene information and the preset speed limit value information.
In the embodiment of the invention, the generated test scene comprises the route information (route number, signal machine switch state and signal machine color) and the temporary speed limit information (line number, speed limit starting point, speed limit end point and speed limit value). Wherein the route information is obtained from the target scene information and the project data table.
