The ATS issues a plan to the train, plans a path required by train operation according to information such as an operation plan issued by the train, a train safety position, a line condition and the like, and inquires whether corresponding resources can be applied to the ATS. After the train obtains ATS approval, the corresponding line resource is applied to the OC, and the mutual exclusion lock is added to the resource on the path through the OC, so that the resource is contended and allocated by multiple trains. The train can only control and pass through turnouts, cross crossover lines and the like on the running path after acquiring the corresponding resource lock, so that the safety protection of the running path of the train is realized.
The current driving resource calculation is extremely dependent on ATS communication and a plan issued by ATS, and the application process and mode of the driving resources are to be further improved:
1. the train uses the planning computing resource of the ATS, and if the ATS communication fails, the train cannot acquire an operation plan, resulting in inefficient operation of the line.
2. When the train applies for the resources, the train firstly inquires whether the ATS can apply for the resources, and then applies for the resources from the OC after obtaining the approval, so that the process can be simplified.
3. When the train obtains the planned turnout needing to be controlled, the train sends a control command to the OC, and the process and the mode can be simplified.
4. The running specific end point of the train-to-train communication system is mutually communicated and calculated by trains, and the mode can be simplified.

And the object controller OC is used for logically controlling and managing trackside resources, receiving the resource allocation of the ATS, locking the resources for the train in advance, checking whether the resources meet the use conditions or not, and sending the resources to the corresponding train to prevent the train from being incapable of driving into the unallowed resources. The ATS transmits the plan and resource allocation to the OC, and the plan and resource allocation are not sent to the train, and the train does not inquire whether the ATS resource can be applied and then the OC applies for the resource. And the OC calculates the resource information, sends the locking state and the allowed use state of the resource to the train, and calculates the required resource by the train according to the running state. If the resource in front of the train can be applied for use by the train, the resource is applied to the OC, and the train can only drive into the corresponding resource area after the permission of use is replied. After the train leaves the area, a resource release command is sent to the OC. And releasing the resources after the OC receives the request, and reallocating the resources according to the actual plan.
An embodiment of the present invention provides an electronic device, which is characterized by including: a memory; a processor; and a computer program; wherein the computer program is stored in the memory and configured to be executed by the processor to implement a resource application method.
An embodiment of the present invention provides a computer-readable storage medium, which is characterized in that a computer program is stored thereon; the computer program is executed by a processor to implement a resource application method.
In the car signal system provided by the embodiment of the invention, the section and the turnout are used as the resources of the travelling crane, wherein the resources of the section are allocated, applied, used and released by taking the virtual section as a unit, and the resources are uniformly scheduled by the ATS according to the virtual section. The switch resource will be included in the switch and the locking of the switch will be stuck with the virtual segment locking. The switch positions of the switches are embodied in the virtual segment description as static configuration data.
The train application method comprises the following steps:
as shown in fig. 3, the train inquires about the nearest traffic signal from the tail of the train and applies for a virtual section between the tail of the train and the traffic signal. The train starts to inquire the signal machine nearest to the train from the tail position of the train to the head direction of the train, and inquires whether the signal machine exists in each axle counting section, and finds out the main signal machine with the first protection direction being the same as the train direction as the nearest signal machine. And counting all virtual sections from the tail to the signal machine, and applying for the locked virtual section resources from the tail to the signal machine according to the locking state of the virtual sections sent by the OC.
As shown in fig. 4, the train inquires about the route according to the traffic signal and applies for virtual zone resources of the route. And the train inquires a route associated with the main signal machine according to the actual states of the electronic map and the turnout, and the route is configured in static data. When the routes associated with the signallers are not unique, a unique route can be confirmed by comparing the corresponding states of the turnout points contained in the routes one by one with the actual states of the turnout points. Acquiring a starting point and an end point of a route, and counting virtual section information between the starting point and the end point. The train is compared with the locked virtual zone resource sent by the OC, and the resource of the route is applied to the OC only when the virtual zone resource of the whole route is completely locked.
As shown in fig. 5, the train will check the protected section of the route. In static configuration data, a route may be configured with protection segments. When the protected zone does not contain switches and is unique, the train can directly determine the protected zone. If the protection section contains a turnout, the train can match a unique protection section according to the actual state of the turnout, if the turnout is four-way or the table is lost, the protection section is considered to be not locked, and the protection section is to be inquired subsequently. The protection zone may include a plurality of virtual zones, the train may check the locking state of the virtual zones one by one, and if all the virtual zones are locked, the protection zone is considered to be locked, and a use application is initiated to the OC.
As shown in fig. 6, the train will request as many successive routes as possible. In the static configuration data, the end signal of one route is the start signal of the next route. When one access is completely locked, if the access has no platform area or is a jumping-off platform area, the train can inquire whether the virtual section of the next access is completely locked or not until the access comprises a non-jumping-off platform area or the access is not completely locked.
When the train turns back, the train will apply for the approach in the reverse direction. The OC sends a retracing virtual section to the train, the train is completely positioned in the virtual section, the train stops accurately in a platform area or stops stably in a non-platform area, and a retracing flow is triggered. Under the turning-back flow, if the train is not turned back, the train uses the head position to inquire the route towards the tail direction; if the train turns back, the train uses the tail to inquire the route in the direction of the head.
As shown in fig. 7, the train will maintain the resources. The resource has the states of not having the application condition, having the allowed use, and the like, and corresponds to the attributes of not locking, having the locked permission, and the like. The condition that the train does not have the application condition means that the train cannot apply for the virtual section in the locked virtual resource list sent by the OC; the virtual zone is positioned in a locked virtual resource list sent by the OC and waits for the application of the train; the permitted use refers to a permitted use state which is sent after the OC agrees after the train applies for. The train checks the state of the resource, if the virtual section is changed from unlocked to locked, the virtual section is recorded as having the application condition, and a use application is initiated to the OC; if the locking is allowed, the application is considered to be successful and no application is required; if the request is changed from the allowed request to the locked request, the request is determined to be required to initiate a use application to the OC; if the locking is changed from the allowed locking state to the unlocked state, the lock is considered to be required to wait for the application.
To sum up, in the car-to-car signal system of the present application, the resource is uniformly scheduled by the ATS according to the virtual zone. And the ATS carries out dispatching distribution of section resources for the train on the line in advance according to the driving plan. Unlike the route handling in existing systems, the ATS system has various section scheduling assignment commands including automatic path locking, automatic section locking, route handling, and the like. In addition, the application and the release of each virtual zone resource in the application are initiated by the train, and the OC feeds the locking state and the use condition back to the train in time after logic judgment.
