Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
At present, the development of the railway network is advanced, and the radio block system is developed to indicate the safety and high efficiency of the train running on the railway. The wireless block system can reduce the dependence on the occupancy detection equipment, so the application of the wireless block system greatly reduces the maintenance cost of the whole railway signal system. At present, in the initial stage of the wide application of the radio block system, the radio block system is frequently upgraded or updated, and after the radio block system is upgraded or updated, a new radio block system needs to be tested first, so that the setting function of the radio block system needs to be tested.
In addition, the radio block system may limit train operation by transmitting a movement authorization for safety during train operation. One element in mobile authorization is the provision of a fail safe area, across which authorized trains cannot cross, to avoid the danger of a train entering the fail safe area. Therefore, how to test the setting function of the fault protection area of the radio block system is a problem to be solved in the field.
Based on the above, the present application provides a test system of a radio block system, as shown in fig. 1, the test system of the radio block system includes three major parts: the system comprises a target wireless blocking system, external simulation equipment and test result detection software. And the target wireless block system receives the instruction and information of the external simulation equipment, and outputs the result to the test result detection software after the fault protection area is set. The external simulation device is a plurality of devices simulating communication with a target wireless blocking system, wherein the adjacent RBC simulation software is used for simulating the wireless blocking system adjacent to the target wireless blocking system. The vehicle-mounted simulation software is used for simulating and testing the train. And the dispatching centralized simulation software is used for sending dispatching instructions to the target wireless blocking system. The interlocking simulation software is responsible for controlling access, signal machines, turnouts and the like, and can send section direction information to the target wireless block system. The temporary speed limit simulation software is used for simulating a speed limit server, namely, simulating to send temporary speed limit information to a target wireless block system. The test result detection software can monitor and analyze a target radio block system test result, wherein the variable detection device detects a variable related to a target radio block system fault protection area setting function. The data packet analyzer can explain the information packets of the captured RBC and the vehicle-mounted or interlocking equipment, and the like, and compare, analyze and judge the result. The maintenance terminal can record information interaction in real time in the running process of the target wireless block system and store the information, and meanwhile, the maintenance terminal can also provide an interface display function, so that the related information of a fault protection area set by the current target wireless block system can be conveniently checked.
Corresponding to the foregoing test system, a method for testing a radio block system is provided, and the specific implementation steps of the embodiment of the present application are shown in fig. 2, and include:
s101: and burning off-line data beside the track of the section paved with the ZPW-2000S system track circuit to a target wireless block system.
The ZPW-2000S system track circuit is one of the current common track circuit types, adopts an integrated structure, has a simple interface, adopts a dynamic detection technology to improve the shunt sensitivity and improve the shunt failure, adopts a multiple safety check mechanism, adopts a closed-loop detection technology to protect a frequency shift signal from receiving crosstalk interference and guiding the frequency shift signal to a dangerous side, and has strong power gasification harmonic interference protection capability. The method and the device test the fault protection area setting function of the target wireless block system by using the railway track section paved with the ZPW-2000S standard track circuit. It should be noted that the railway track section is divided into an intra-station section and an inter-zone section, and the inter-zone section is specifically designated in this application.
The trackside off-line data is data of a real site and can comprise track section information, logic section information, ZPW-2000S system track circuit data and the like, and the target wireless block system can know the site condition of the test train in operation through the trackside off-line data.
In the embodiment of the application, before testing the target wireless block system, off-line data beside the track of the section where the ZPW-2000S standard track circuit is laid needs to be burned into the target wireless block system, so as to simulate a real site applying the target wireless block system.
It should be noted that the embodiment of the present application is not only suitable for simulation testing in a laboratory, but also suitable for field testing. It should be noted that before the test step is executed, the running direction of the test train may be selected, and the running direction of the test train includes: an uplink positive direction, an uplink negative direction, a downlink positive direction and a downlink negative direction. According to the embodiment of the application, the target wireless block system can be tested for multiple times by selecting different running directions of the test train, so that the test accuracy is improved. Also, before the test step is executed, it may be set whether the target radio block system checks a small track in the ZPW-2000S system track circuit. In practical application, whether the small track is included in the inspection can be selected according to engineering requirements, and the embodiment of the application has the function of including or not including the small track. Wherein, the small track is a logic track in ZPW-2000S track circuit. In the ZPW-2000S system track circuit, the track is divided into a main track and a small track. The track section divided by the electric insulation joints, and a line between the transmitting end tuning unit and the receiving end tuning unit is called a main track. The electric insulation section divides the track section, and a tuning area for isolating signals is arranged between two adjacent main tracks, and the section of the circuit is called a small track.
S102: and transmitting train registration information to the target wireless block system.
When a target fault protection area setting function test of a target wireless block system is started, a test train is firstly registered in a section where a ZPW-2000S standard track circuit is laid, namely, a test train is driven in the section, and the train is registered on the track, which indicates that the current test train is positioned on the track. At this time, since the target radio block system is a radio block system that controls the section, the target radio block system may receive train registration information corresponding to the test train transmitted by the test system, the train registration information indicating that the test train is located on the first track of the section. After the target wireless block system receives the train registration information, the condition that the target wireless block system sends the movement authorization to the test train is met, and then the target wireless block system can set a target fault protection area aiming at the test according to the front condition of the test train.
S103: simulating a fault point on a second track of the section ahead of the test train travel.
The failure point in the embodiment of the present application refers to a failure point considered by the target radio block system. For example: 1. the target wireless blocking system receives the information that a certain track is occupied from the interlocking simulation software when no train exists on the track of the section, and the target wireless blocking system sets the track fault at the moment; 2. testing communication interruption between the train and a target wireless block system in the running process; 3. a failure of the axle counting device, etc.
After receiving the information of the fault point, the target wireless block system sets a target fault protection area for the test train according to the position of the fault point and the information of the track near the fault point, wherein the information of the track near the fault point is obtained according to the off-line data beside the track, so as to prevent the test train from crossing the target fault protection area.
S104: and monitoring whether the target wireless block system outputs the target fault protection area, and if the target fault protection area is output, determining that the fault protection area setting function of the target wireless block system is normal.
After the fault point is simulated, the test system monitors whether the target wireless block system outputs the target fault protection area, if the target fault protection area is output, the fault protection area setting function of the target wireless block system is normal, and if the target fault protection area is not output, the fault protection area setting function of the target wireless block system is abnormal.
In the embodiment of the application, a target wireless block system is tested by simulating a fault point on a section where a ZPW-2000S system track circuit is laid. The method and the device realize the judgment of whether the setting function of the fault protection area of the wireless block system is normal or not and improve the reliability of the setting function of the fault protection area of the wireless block system.
On the basis of the embodiment shown in fig. 2, in another embodiment of the present application, for a test train to simulate a fault point on a second track, specific steps are shown in fig. 3, and include:
s201: simulating that the second track is in an occupied state, so that the target wireless block system sends a conditional emergency stop message (CEM) to the test train.
When the target wireless blocking system receives the information that the second track in front of the running test train is in the occupied state, the target wireless blocking system sends a CEM (Conditional Emergency Stop Message) to the test train so that the test train can judge whether the train occupying the second track is a self train or other trains, if the train is other trains, the test train replies CEM considering information to the target wireless blocking system, and if the train is the self train, namely the test train occupies the self train, the test train replies CEM ignoring information to the target wireless blocking system. And the target wireless block system judges whether a target fault protection area is set or not according to the received reply information of the test train.
Note that the CEM check is not performed on the sector before the fault point is simulated.
S202: detecting whether the target radio block system receives CEM consideration information of the test train responding to the CEM.
The CEM consideration information is used to indicate that the fault point exists before the test train approves travel. After the vehicle-mounted simulation software, namely the test train, replies the CEM consideration information to the target test system, the test system can detect whether the target wireless block system receives the CEM consideration information replied by the test train through packet capture.
S203: if so, continuing to execute the subsequent test.
S204: and if not, displaying that the setting function of the fault protection area of the target wireless block system is abnormal.
According to the method and the device, the rail in front of the advancing direction of the test train is simulated to be occupied, the target wireless block system is triggered to carry out CEM (cellular element management) inspection, and then the message is considered according to the CEM replied by the test train, so that the target wireless block system sets the target fault protection area. In the testing process, whether the target wireless block system receives the CEM consideration information replied by the target testing system or not is detected, so that whether the setting function of the fault protection area is normal or not can be timely known in the process of setting the fault protection area by the target wireless block system, and if the target wireless block system does not receive the CEM consideration information, the testing system directly displays that the setting function of the fault protection area of the target wireless block system is abnormal, so that the testing time is shortened.
On the basis of the embodiment shown in fig. 2, in another embodiment of the present application, for a test train to simulate a fault point on a second track, specific steps are shown in fig. 4, and include:
s301: setting the second track to be in close proximity to the first track so as to trigger the target wireless block system to perform close proximity occupancy check.
In this embodiment, if the second track is close to the first track, the target radio block system is triggered to perform close occupancy check. Specifically, the second track is a next track of the first track in the traveling direction of the test train. During the process of running of the test train, the target wireless blocking system performs an adjacent occupation check once when the test train runs on one track, so as to detect whether the next adjacent track (second track) of the track (first track) where the current test train is located is in an occupied state, and if the adjacent track is in the occupied state, the target wireless blocking system authorizes the test train to stop.
It should be noted that the section is not immediately checked for occupancy until the simulated failure point.
S302: and simulating the falling of a relay corresponding to the second track in the ZPW-2000S system track circuit.
The ZPW-2000 series track circuit takes a steel rail as a conductor and is used for automatically and continuously detecting whether a line is occupied by a train, and when a relay corresponding to a second track falls down, the ZPW-2000 series track circuit is interrupted, so that the close occupation inspection of a target wireless block system is influenced. At this point, the target radio block system will receive information that the close occupancy check failed. When the adjacent occupancy check fails, the target wireless block system cannot know whether the adjacent track of the test train is in an occupied state, and the target wireless block system equates the adjacent occupancy check failure to the adjacent second track having a fault, so that the target wireless block system sets a target fault protection area according to the second track.
S303: detecting whether the target radio block system receives close occupation check failure information.
When the target wireless blocking system carries out the close proximity occupancy check, the test system can detect whether the target wireless blocking system receives a close proximity occupancy check failure message or not through packet capture.
S304: if so, continuing to execute the subsequent test.
S305: and if not, displaying that the setting function of the fault protection area of the target wireless block system is abnormal.
The close proximity occupancy check is a check frequently performed in the operation process of the target wireless block system, that is, the probability of setting the fault protection area through the failure of the close proximity occupancy check is higher, and the embodiment of the application selects a scene with higher probability to perform the test, so that the test accuracy is improved.
On the basis of the embodiment shown in fig. 2, in another embodiment of the present application, before monitoring whether the target radio block system outputs the target fail-safe region, the method further includes the following steps:
and verifying whether the position of the target fault protection area is accurate.
The embodiment of the application can test whether the target wireless block system can output the target fault protection system or not and can test the position accuracy of the target fault protection area set by the target wireless block system.
In an implementable manner, the following steps are specifically included:
s401: after the target wireless block system determines a first fault protection area according to the fault point, verifying whether the first fault protection area is the second track.
When the target radio block system receives the information of the fault point, the target radio block system firstly sets the track where the fault point is located as a first fault protection zone, that is, the length of the first fault protection zone is the length of one track. And resetting the target fault protection area on the basis of the first fault protection area. In the embodiment of the application, the fault point is simulated on the second track, so that the test system can judge whether the target wireless block system uses the second track as the first fault protection area, that is, the test system can judge whether the wireless block system finds the position of the fault point accurately.
S402: if so, acquiring the target fault protection area determined by the target wireless block system according to the first fault protection area and the trackside offline data.
When the test system detects that the first fault protection area set by the target wireless block system is the second track, the target fault protection area set by the wireless block system can be obtained, the target fault protection area set by the wireless block system is compared with the estimated fault protection area calculated by the test system, and the accuracy of the target fault protection area is determined.
S403: and determining the pre-estimated fault protection area according to the fault point, the section direction information of the section and the boundary condition of the fault protection area.
The direction information of the sector includes a sector directional direction and a sector non-directional direction. The sector oriented direction may be the sector direction being an uplink direction and the sector direction being a downlink direction. If the section has no direction, the test train can run towards any direction at two sides.
After the target radio block system determines the first fault protection zone, the fault protection zone needs to be extended according to the zone direction information and the boundary condition of the fault protection zone, so as to obtain the target fault protection zone.
The fault protection zone boundary condition refers to that in the process of extension, the nearest one of the relevant boundaries of the fault protection zone is selected as the boundary of the target fault protection zone, wherein the relevant boundaries of the fault protection zone are, for example: 1. counting the axis boundary between stations in front; 2. another zone boundary with the front already set; 3. estimating a rear end of the front communication train; 4. the RBC jurisdiction boundary of the front CTCS-N (China Train Control System-Next Generation) level is operated.
In one case, the method specifically comprises the following steps:
s4031: when the section has a direction, the fault point is taken as a starting point, a boundary which is closest to the fault point in the related boundaries of the plurality of fault protection regions is searched according to the direction of the section, the fault point is taken as the starting point, the searched boundary is taken as an end point, and the estimated fault protection region is determined.
It should be noted that the starting point in the embodiment of the present application refers to an end point on the second track corresponding to the fault point, which is close to one end of the test train.
S4032: when the section has no direction, the fault point is taken as a starting point, the boundary which is closest to the fault point in the related boundaries of the plurality of fault protection areas is respectively searched for two sides, the two searched boundaries are respectively taken as a starting point and an end point, and the estimated fault protection area is determined.
It should be noted that, when the section has no direction, it needs to extend to both sides of the fault point to search for a boundary, and when the boundary close to the side of the test train is determined, if a boundary related to the fault protection area is not found between the fault point and the test train, the end point of the track adjacent to the current test train is used as the boundary of the estimated fault protection area.
S404: and comparing the positions of the target fault protection area and the estimated fault protection area.
And comparing the target fault protection area set by the target wireless block system with the position of the target fault protection area determined by the test system so as to judge whether the position setting of the target fault protection area is accurate.
S405: if the positions are the same, the subsequent tests are continuously executed.
S406: and if the positions are different, displaying that the setting function of the fault protection area of the target wireless block system is abnormal.
The embodiment of the application aims to test the setting function of the fault protection area of the target wireless block system, so whether the position of the target fault protection area is accurate is an important index for evaluating the setting function. According to the embodiment of the application, the position of the first fault protection area is judged, and then the position of the target fault protection area is judged, so that the function of setting the fault protection area of the target wireless block system can be accurately tested, and the test standard is improved.
On the basis of the above embodiment, in another embodiment, the CEM and the close proximity occupancy check may be combined to test the target radio block system, and the CEM may be used to simulate a fault point to test whether the target radio block system has set one target fail-safe region, and then the close proximity occupancy check is used to simulate the fault point to test whether the target radio block system has set another target fail-safe region. That is, in the process of testing performed once, different multiple target fail-safe regions are set, and the function of setting multiple target fail-safe regions by the target radio block system can be tested.
In an implementation manner, the section in which the ZPW-2000S Track circuit is laid is a Train Track Detect (TTD) section, the T _ occupancy of the TTD section continues to be an occupancy state without a Train safety envelope, and the TTD section has no fault protection area and is not subjected to a CEM check and an adjacent occupancy check, and is an interval section. If the target radio block system sets a target fail-safe region for the TTD zone, the first fail-safe region may be extended as follows to obtain the target fail-safe region.
When the section has a direction, the first fail-safe region can be propagated to the following nearest positions of the section according to the section direction:
(1) Counting the axle boundary between stations in front;
(2) The front has been set as the boundary of the guard area;
(3) Estimating a rear end of the front communication train;
(4) Run the current RBC jurisdictional boundary of the previous CTCS-N level.
When the section has no direction, the first fail-safe region may be extended to the following nearest positions of the section according to the left and right sides of the TTD section, respectively:
(1) Counting the axle boundary between stations in front;
(2) The front has been set as the boundary of the guard area;
(3) Estimating a rear end of the front communication train;
(4) Run the present RBC jurisdictional boundary for the previous CTCS-N level.
Before the test is executed, if the small track is selected to be taken into the inspection, the following specific conditions can be provided according to the running direction of the test train:
1. in the forward downward direction, as shown in fig. 5 a:
and registering the test train on the 1G main track, and when the 2G changes from idle to occupied, the target wireless blocking system makes CEM for the track section, and the target wireless blocking system sets an emergency stop point as the 2G main track entrance, namely a point c, in a CEM message sent for the test train. If the CEM check fails, the target radio block system sets a first failure protection zone in the cd (main track) of 2G, and extends the first failure protection zone to obtain a first target failure protection zone.
And then, carrying out close-proximity occupancy check on the 2G, and when the close-proximity occupancy check fails, extending the second first fault protection area by the target wireless block system in the second first fault protection area of the cd (main track) of the 2G to obtain a second target fault protection area. The boundary positions of the first target fail-safe zone and the second target fail-safe zone are the same.

If the CEM check fails, the target wireless block system sets a first fault protection area in 2G dc (main track), and extends the first fault protection area to obtain a first target fault protection area.
And then, carrying out close-proximity occupancy check on the 2G, and when the close-proximity occupancy check fails, extending a second first fault protection area of the target wireless block system in the second first fault protection area of the dc (main track) of the 2G to obtain a second target fault protection area. The boundary positions of the first target fail-safe zone and the second target fail-safe zone are the same.
3. For a mechanical insulation joint, as shown in fig. 5 c:
the track section only consists of a main track, a test train is registered on the track before 1G, when 1G is changed from idle to occupied, the target wireless blocking system does CEM on the track section, and the target wireless blocking system sets an emergency stop point as the entrance of the 1G main track, namely a point b, in a CEM message sent for the test train. If the CEM check fails, the target wireless block system sets a first fault protection area in ba (main track) of 1G, and extends the first fault protection area to obtain a first target fault protection area.
