Technical Field

Background
The route trigger is a core function of the vehicle-mounted ATS (Automatic Train Supervision, train automatic monitoring system) for realizing the automatic route of the train. In CBTC (Communication Based Train Control System, communication based automatic train control) systems, a corresponding physical segment is typically configured for a route, and when a communication/non-communication train occupies the segment, the trigger logic for the route is initiated by the on-board ATS. The resource occupation application is a core function in a train communication system, and in the running process of a train, the corresponding resource occupation application needs to be triggered according to the distance between the train and a resource point.
At present, although the route trigger logic in the ATS systems of the signal devices is different, the ATS systems generally automatically generate a route command according to train information and an interlocking device state and send the route command to the interlocking system by configuring a condition that a corresponding physical section occupies the route trigger logic, for example, when a train runs to a trigger rail section. However, since the trigger occupied by the physical section has a scene that the trigger track and the trigger path belong to different interlocking areas, the trigger logic needs to involve information interaction between the interlocking areas, so that the trigger logic is complex. And because the physical section has a certain length, the traditional way is used as a condition of route trigger logic according to whether the physical section enters the trigger rail section, the route is usually required to be triggered in advance, namely the trigger distance is larger than the distance required by various safety requirements of the train running, so that the train still needs to run for a certain distance after running for a sufficient safety distance to complete route trigger, the trigger distance is longer, the trigger efficiency is low, and real-time and accurate triggering cannot be realized. And the system resources during the period cannot be fully used due to the longer triggering distance, so that the utilization rate of the system resources is low.

Detailed Description
The invention is further described below in connection with the drawings and the specific preferred embodiments, but the scope of protection of the invention is not limited thereby.
As shown in fig. 1, the steps of the train driving path resource application method of the embodiment include:
and S01, generating path information of the train on the target line according to the connection relation between the line resources of the trackside equipment.
The route resources include switches, stations, parking areas, turning back tracks, etc., and the route information includes the sequence of trains passing through the stations, time, section information between the stations, distance information between the sections, etc. The path information generally contains only one piece of path information, and if there are subways mixed by different intersections and sizes, 2 to 3 pieces of path information exist. And generating all path information on the operation line according to the operation plan requirements by the vehicle-mounted ATS according to the connection relation of each line resource in the line.
In a specific application embodiment, drawing ATS system data through a trackside equipment layout diagram, wherein the data comprises bidirectional link relations of all trackside equipment such as track sections, stations and the like; then selecting a daily running route for compiling running path information for all train numbers in the day, wherein the path information comprises the sequence and time information of the train numbers passing through each station; then according to the plan operation information in the current operation chart, station information of each train number which runs on the current operation is obtained; and inquiring track section information and distance between sections contained between each station through ATS system data, and combining path information in the running chart and section length data in the line data to obtain path information of each train number on the running line, wherein the path information comprises the sequence of passing stations, time, sections between each station, distance information of each section and the like.
And S02, determining line resources to be applied according to the running path information of the train plan.
The running path information of the train plan can determine that the train needs to pass through the platform and the road section, so that the line resources required to be applied can be determined, and the line resources required to be applied are stored in the ATS system.
And S03, monitoring the position of a locomotive in the running process of the train in real time.
Step S301, the train reads information of the transponder every time the train passes the transponder arranged on the track;
s302, collecting measurement information of pulse speed measuring sensors arranged on wheels of a train;
and S303, determining the position of the train head in the line according to the read information of the transponder and the measurement information of the pulse speed measuring sensor.
In order to ensure the accuracy of the head position monitoring, the embodiment realizes the head position positioning by adopting a mode of combining a transponder with the speed measurement of the dual-speed sensor. Transponders are arranged at intervals in the center of the track, and when a train passes the transponders, the position of the train head in the line can be positioned by reading the information of the transponders. However, in practice, the train is subject to disturbances and errors due to irregular movements of the wheels, such as spin, slip, etc., and wear of the edges of the wheels. According to the embodiment, on the basis of transponder positioning, a double-speed sensor is further combined, the photoelectric pulse speed measuring sensor is arranged on wheels of a train, the wheels rotate when the train runs, the sensor measures the number of wheel rotation pulses to obtain the running distance of the train, the speed and the real-time accurate position of the train can be calculated by combining the time used by the accumulated number of pulses, and therefore the accuracy of path resource application is further ensured, and the path triggering distance of the path resource application is reduced as much as possible.
It will be appreciated that other manners of positioning the head position may be adopted according to actual needs, besides the foregoing manners of positioning the head position.
And S04, judging whether to trigger a resource acquisition application according to the distance between the head position of the train and the line resource required to be applied in front, wherein when the head position of the train reaches a preset path trigger distance value from the line resource required to be applied in front, triggering and sending the resource acquisition application.
In this embodiment, the preset path trigger distance value may be obtained by superimposing a vehicle braking distance and a train running distance in response time, where the train running distance in response time includes a train running distance in a time required for issuing a command by the vehicle-mounted ATS, a train running distance in response time of the vehicle-mounted ATS, a train running distance in corresponding time of the track bypass line resource management system, and a train running distance in turnout moving time. For example, the preset path trigger distance value can be obtained by using the train service braking distance, the train running distance in the ATS command issuing time, the train running distance in the on-board ATP response time, the train running distance in the resource controller response time and the train running distance in the switch moving time.
The train is driven to a certain resource at a speed V, and when the train is distant from the resource by S meters, the system sends a resource acquisition application, wherein S is the path trigger distance. In a specific application embodiment, the deceleration b, the approach speed V, the resource end point SHP, the braking distance SB, and the train running distance SR within the system response time are defined, where the train running distance SR within the system response time includes the interlock t1, the ATP, and the train response time t2, the path trigger distance S may be calculated according to the following formula:
from the above, the path trigger distance S that can satisfy the train safety requirement can be accurately calculated after the deceleration b of the train and the approach speed V are obtained. After the path trigger distance S is calculated, whether the route resource passing through the head and the front of the train reaches the path trigger distance S or not can be monitored in real time, so that the application of the path resource can be accurately triggered, the triggering mode based on the triggering track section as a triggering condition does not need to trigger in advance like the traditional triggering mode, the triggering accuracy can be greatly improved, the path trigger distance is shortened, and the real-time and accurate application of the path resource is realized.
It can be understood that the path trigger distance value can also be configured in a specific calculation mode according to actual requirements.
In this embodiment, triggering the sending a resource acquisition application specifically includes:
the vehicle-mounted ATS system sends a resource application command to the vehicle-mounted ATP system;
after receiving the resource application command sent by the vehicle-mounted ATS system, the vehicle-mounted ATP system applies for distributing corresponding line resources to the track side line resource management system.
In this embodiment, triggering the sending a resource acquisition application further includes:
the vehicle-mounted ATP system periodically receives allocation status information of the track bypass line resources sent by the track bypass line resource management system;
if the permission of using the corresponding line resource is obtained, the MA (driving license) is operated according to the MA (driving license) calculated by the vehicle-mounted ATP system;
and after judging that the corresponding line resources are used, the vehicle-mounted ATP system sends a trackside resource release application instruction to the trackside line resource management system.
The embodiment also provides a train driving path resource allocation management method, which comprises the following steps:
receiving a resource application allocation request sent by a train-mounted ATP system according to the path resource application method;
when a resource application allocation request sent by a train-mounted ATP system is received, carrying out line resource conflict security verification;
and after the safety verification is passed, corresponding line resources are distributed to the application train, and distribution state information is sent to the vehicle-mounted ATP system.
In a specific application embodiment, as shown in fig. 3, the ATS system generates path information of all lines, and at the same time, the ATS system sends planned operation path information to the vehicle-mounted ATC based on the operation plan; the system judges whether the communication vehicle exists on the line, if so, the system determines the line resource needing to be triggered in the path of the communication vehicle based on the planned running path information. When the distance between the accurate position of the train head in the range of the planned running path and the line resource (switch, parking area, garage door and the like) to be passed in front reaches the preset path triggering distance in the running process of the train, the ATS starts to send a path request command of the resource to the train, and when the vehicle-mounted ATP receives the resource application command of the ATS, the ATS sends a path resource application to a track side line resource management system (OC) to request to allocate the resource of corresponding equipment.
The trackside resource management system (OC) is responsible for managing the allocation status management of all line resources (switches, stations, return tracks, etc.) within the local control zone. After the trackside resource management system (OC) receives the application of the controlled communication train for allocating the trackside line resources, the application resources are allocated in a first-to-first-obtained mode, and the trackside resource management system (OC) comprehensively manages the allocation state of the line resources, so that the same resources can only be occupied by a train at the same time. Meanwhile, the resource controller performs the line resource conflict safety check, and after the check condition is passed, the line resource is distributed to the application train. And if the conflict security check fails, sending an alarm prompt to the ATS and the train application. And after the trackside resource management system (OC) completely allocates the resources, sending the resource allocation status information to the vehicle-mounted ATC system.
The vehicle-mounted ATP periodically receives allocation status information of the track side line resources (turnout, parking area and garage door) sent by the OC, and if the allocation status information is acquired to occupy the resources, the vehicle-mounted ATP has control and use rights on the resources. When the train judges that the resources are used up, the vehicle-mounted ATP sends a trackside resource release application instruction to the OC. The trackside resource management system (OC) is configured to receive and execute only release instructions for a target train held by the resource.
According to the method, the distance between the accurate position of the train head and the resource to be passed in the front path is calculated in real time, the distance between the position of the train head and the path resource is used as the path triggering distance, when the condition that the path triggering distance is met is judged, the path resource application is triggered, after the train receives a resource request command, the trackside resource controller is applied for a request for occupying the resource, the path resource application can be accurately triggered based on the position of the train head, compared with the traditional method based on whether the track section is triggered as a triggering condition or not, the triggering distance can be set more accurately without triggering in advance, so that the resource request is more accurate, the limitation of the position of a physical section or an interlocking area is avoided, the occupation information of the physical section is not required, and the method can be suitable for realizing more flexible path resource application in the whole range of the train.
To further illustrate the effectiveness of the present invention, taking fig. 4 as an example, there is a train running to the left on TTT04 track (white filled light band indicates train body, grid filled light band indicates movement authorization of train, no. 62 switch is 50 meters long in reverse, TTT02 section is 250 meters long, TTT03 section is 250 meters long), and No. 61 switch resource needs to be applied. The distance from the boundary B point on the left side of the TTT03 to the No. 61 turnout is 300 meters, and the triggering distance from the No. 61 turnout is 302 meters, and the TTT03 track is provided.
The traditional path resource application mode based on the trigger track section is that when a train just enters a TTT03 track, the system judges that the train enters the TTT03 trigger track, and then starts to apply for triggering No. 61 resources, and at the moment, the train head is triggered at a distance of 248 meters from No. 61 turnout 550 meters earlier than the expected distance of 302 meters. In the timing system, the triggering is always performed at a certain position in the section, so that the resource application is triggered each time. By adopting the path resource application method, the distance between the accurate position of the train head and the No. 61 turnout is used as a trigger condition, and the ATS starts to trigger the application of the No. 61 turnout to the vehicle-mounted ATP only when the train head reaches the point B, so that the application of the path resource can be accurately triggered according to the accurate resource application time, the application is prevented from being triggered in advance, the path trigger distance is shortened, and the use efficiency of system resources (key resources such as turnouts, platforms and turning back rails) is effectively improved, thereby improving the system tracking efficiency.

the application triggering unit is used for judging whether to trigger the resource acquisition application according to the distance between the head position of the train and the line resource required to be applied in front, wherein when the head position of the train reaches a preset path trigger distance value from the line resource required to be applied in front, the resource acquisition application is triggered and sent.
The path generating unit, the resource determining unit and the position monitoring unit are arranged in the vehicle-mounted ATS system, the application triggering unit comprises a resource application command transmitting subunit and a resource application request transmitting subunit, the resource application command transmitting subunit is arranged in the vehicle-mounted ATS system and used for transmitting a resource application command to the vehicle-mounted ATP system, and the resource application request transmitting subunit is arranged in the vehicle-mounted ATP system and used for applying for distributing corresponding line resources to the on-track line resource management system after the vehicle-mounted ATP system receives the resource application command transmitted by the vehicle-mounted ATS system.
In this embodiment, the system further includes a resource allocation status monitoring unit connected to the application triggering unit, so as to periodically receive allocation status information of the track bypass line resource sent by the track bypass line resource management system; if the permission of using the corresponding line resource is obtained, operating according to MA calculated by the vehicle-mounted ATP system; and after judging that the corresponding line resources are used, sending a trackside resource release application instruction to a trackside line resource management system, wherein the resource allocation state monitoring unit is arranged in the vehicle-mounted ATP system.
It can be understood that the main body for triggering the occupation of the resources is implemented by the ATS system, but the function can also be put on the vehicular ATC, and the vehicular ATC triggers the path resource application command according to the distance between the accurate position of the vehicle head and the resource point in front of the path.
