And a route switching method at the fault stage of the train.
Background
The method comprises the steps that a train operation control system (a typical train autonomous operation system or a train operation control system based on vehicle-to-vehicle communication) supporting vehicle-mounted equipment is a train handling route (a train walking path on a track is different from a traditional interlocking route taking a signal machine as a starting end), under a normal condition, the vehicle-mounted equipment of the train handles the route for the train, resources related to the route are obtained, driving permission is calculated according to the resources, under a fault condition (such as vehicle-mounted equipment fault, communication fault and the like), degradation route management equipment handles the route for a fault train, and the resources related to the route are obtained, and the driving permission is calculated according to the resources.

1) The method comprises the following steps of canceling an original route (transacting by degraded route management equipment) and transacting a new route (transacting by vehicle-mounted equipment) again, and the like, and carrying out manual intervention, wherein a train needs to be stopped in the process;
2) And after the train which is recovered to be normal continues to run to the destination platform according to the degradation mode, the original route is automatically unlocked, and the normal running of the train is recovered by the way that the vehicle-mounted equipment handles the route and the like.
Both of the above two modes have the problem that the operation of the advanced mode (such as CM, AM, FAM and the like) cannot be quickly recovered after the train is recovered to be normal.
Disclosure of Invention
In this summary, a series of simplified form concepts are introduced that are simplifications of the prior art in this field, which will be described in further detail in the detailed description. This summary of the invention is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
The invention aims to provide a train fault stage route switching system and a train fault stage route switching method, which are applied to a train operation control system for supporting a vehicle-mounted device to handle a route for a train (a train walking path on a track, which is different from a traditional interlocking route taking a signal machine as a starting end), can be immediately and automatically upgraded to a high-grade mode (such as CM (CM), AM (amplitude modulation), FAM (failure mode) and the like) to operate in a train fault stage and/or a train fault recovery stage, and realize degraded route and vehicle-mounted route seamless switching.
In order to solve the above technical problem, the route switching system for a train failure stage provided by the present invention includes a degraded route and a vehicle-mounted route, and the train failure stage includes a train failure stage and/or a failed train recovery operation stage, including:

it should be noted that the route sent to the on-board device or the route sent to the degradation route management device carries information of an actual user-train of the route;
the resource management and registration equipment is used for managing and registering the holding condition of the resource, and the recorded information at least comprises a requester of the resource, a user of the resource and the use state of the resource;
optionally, in a normal case (in some cases, a certain type of resource may be used by multiple devices together, and the exception does not affect the content of the patent), the right of use of the resource on the route has mutual exclusion and exclusivity between routes, that is, multiple routes are not allowed to obtain the right of use of the resource at the same time, when routes are arranged, a method of obtaining the resource on the route first and then calculating the driving permission on the obtained resource is adopted, so that when multiple trains or multiple devices are arranged for routes, the driving permissions of multiple routes do not overlap with each other, and further, train collision is prevented; the resource sharing in the general sense refers to that resources are shared among a plurality of devices, for example, a plurality of trains share a certain resource, since train bodies cannot be overlapped physically, and the resources on a common driving path of the trains cannot be used by the plurality of trains simultaneously, therefore, the sharing is subject to a limited condition, for example, the resources in a non-overlapping area of shared routes (limited in space), or the resources in an overlapping area of shared routes but limited by other technical means to not be used simultaneously (limited in time), two routes share the resources in an overlapping area of routes as described in the patent, and when the resources in the overlapping area are held by one route of the train, two routes of the same train can authorize the train to use the resources in the overlapping area simultaneously, and are essentially one device and one train resource.
When a train fails, after receiving the route of the failed train, the degradation route management equipment requests to hold resources related to the route, the requested resources are registered and managed by the resource management equipment, applicants of the resources are the degradation route management equipment, and users are (failed) trains;
after the train is recovered to normal, the vehicle-mounted equipment receives the route request and requests to hold the resources related to the route, because the resources acquired by the degradation route management equipment are used by the fault train, the resources requested by the vehicle-mounted equipment are also used by the same train, namely the two routes and the users of the resources on the routes are the same train, the vehicle-mounted equipment can share the resources acquired by the degradation route management equipment, namely the two routes handled by the two equipment for the same train share the resources in the overlapping area on the routes, and at the moment, the vehicle-mounted equipment and the degradation route management equipment handle the routes for the same train at the same time and calculate the driving permission at the same time.

Optionally, the route switching system at the fault stage of the train is further improved, and resources no longer needed by the train passing area are released or handed over when the vehicle-mounted equipment and the degraded route management equipment jointly confirm that the resources are no longer needed;
or, the selection is released or handed over by the vehicle-mounted equipment
Or, alternatively, released or handed over by the original requester.
It should be noted that the resources of the same train can only be shared by the onboard device of the train and the degraded route management device for managing the degraded route for the train, and the resources in the route overlapping area cannot be shared between the onboard device and the onboard device, and between the degraded route management device and the degraded route management device.
Optionally, the route switching system in the train fault stage is further improved, when the on-board device transacts the route, the degraded route management device shares resources in the route overlapping area with the on-board device of the train, and during the route resource sharing period, the degraded route management device does not receive and does not execute a new route request or an extended route request of the train.
Optionally, the route switching system in the train failure stage is further improved, and if the consumption of the degraded route handled by the degraded route management device for the degraded train is completed, or an operator cancels or manually unlocks one of the routes, the degraded route management device and the vehicle-mounted device of the train terminate sharing the resources in the overlapping area of the routes.
In order to solve the technical problem, the invention provides a route switching method for a train at a fault stage, which comprises the following steps:
s1, after receiving a route request, the trackside equipment transacts a route for a fault train, requests resources, calculates driving permission and manually drives the train to run according to the driving permission;

or the running permission calculated by the train meets the requirement of upgrading the running mode to the advanced mode running or can maintain the normal running of the train in the current mode, the trackside equipment is not informed, and the train and the trackside equipment handle the approach respectively;
and S6, if the degraded route management equipment consumes the degraded routes handled by the degraded train, or an operator cancels or manually unlocks one of the routes, the degraded route management equipment and the vehicle-mounted equipment of the train terminate the sharing of the resources in the route overlapping area.

Optionally, the route switching method at the train fault stage is further improved, and if the consumption of the degraded routes handled by the degraded route management device for the degraded train is completed, or an operator cancels or manually unlocks one of the routes, the degraded route management device and the vehicle-mounted device of the train terminate sharing the resources in the route overlapping area.
It should be noted that, the on-board device and the degradation route management device both have control right of resources in the route overlapping area, and control commands of them are consistent except for the traffic signal, and the resource control device can select to execute the control command of the on-board device or the degradation route management device.
For controlling the signal machine, the degradation route management device outputs the display command of the signal machine according to the principle of fixed blocking, and the vehicle-mounted device outputs the display command of the signal machine according to the principle of fixed blocking or moving blocking according to different driving modes of the train. And when receiving a permission signal display command of the vehicle-mounted equipment or the degradation route management equipment, the resource control equipment controls the annunciator to display a permission signal.
The situations related to the switching of the degraded access and the vehicle-mounted access in the invention are as follows:
1) When a fault train is recovered to operate, the train enters the route after the degraded route, and the operation of the condition has the requirements of no-stop, automatic and noninductive upgrading;
2) When a train fails, a degraded route is formed after the prior train route, and in the situation, manual intervention is usually required in operation, so that the requirement for seamless switching of the train route to the degraded route is not high, but the technical scheme is also suitable for the situation.
