Abstract

The present disclosure relates to a portable safety terminal based method for processing rail transit resources, and a system for the method. The method includes: in a degradation mode, performing interaction between a portable safety terminal and a wayside controller; providing a driver with safety display of an environment where a train is located, and obtaining a location of the train and information of a relationship between a front train and a rear train; and providing the driver with a means to apply for line resources, such that the driver can, according to the train environment, autonomously apply for the line resources, and release the resources for use by subsequent trains after driving the train to pass through a zone. Compared to the prior art, the present disclosure has the advantages of improving the safety of train driving and field maintenance operation, etc.

First claim

The invention claimed is:

1. A portable safety terminal based method for processing rail transit resources, the method comprising: in a degradation mode, performing interaction between a portable safety terminal and a wayside controller; providing a driver with safety display of an environment where a train is located, and obtaining a location of the train and information of a relationship between a front train and a rear train; and providing the driver with a means to apply for line resources, such that the driver can, according to the train environment, autonomously apply for the line resources, and release the resources for use by subsequent trains after driving the train to pass through a zone.

2. The portable safety terminal based method for processing rail transit resources according to claim 1 , wherein the interaction between a portable safety terminal and a wayside controller comprises interaction between safety display information and interaction between safety control commands.

3. The portable safety terminal based method for processing rail transit resources according to claim 2 , wherein the interaction between safety display information specifically comprises:
obtaining, by the portable safety terminal, information of the line resources and a status of wayside equipment from the wayside controller, and performing display on a display interface.

4. The portable safety terminal based method for processing rail transit resources according to claim 3 , wherein the obtained information of the line resources and status of wayside equipment comprise: the location of the train, a status of track occupation, a position of a switch, a status of a signal, a status of zone blocking, a status of a platform door, a status of a platform emergency close button, and a working status and alarm display of the equipment.

5. The portable safety terminal based method for processing rail transit resources according to claim 2 , wherein the interaction between safety control commands specifically comprises:
Step 1): after a status of wayside equipment in the environment where the train is located is obtained, applying to the wayside controller for track resources required for train operation and a control authority of the wayside equipment by an operating button on the portable safety terminal, and after the wayside controller confirms that the track resources are not occupied by other controller or the portable safety terminal, authorizing the portable safety terminal to control the track resources;
Step 2): after the control authority of the wayside equipment is obtained, selecting, by the portable safety terminal, corresponding elements, icons, or menus on a display interface to control the corresponding wayside equipment to act; and
Step 3): after the control on the wayside equipment is completed and the line resources are obtained, autonomously driving the train to pass through the control zone according to the display on the portable safety terminal; and after the train passes through the control zone, releasing the line resources via the operating button on the portable safety terminal, and returning the control authority of the wayside equipment for continued use by the subsequent trains or the wayside controller.

6. The portable safety terminal based method for processing rail transit resources according to claim 5 , wherein the operating button is a physical button or a touch screen.

7. The portable safety terminal based method for processing rail transit resources according to claim 5 , wherein the control authority of the wayside equipment is executed by secondary confirmation, a user name/password, or a biological recognition technology, or is executed by combination of a plurality of means.

8. The portable safety terminal based method for processing rail transit resources according to claim 5 , wherein actions in Step 2) comprise: handling of a train route, individual operation of a switch to a normal position/a reverse position, individual locking/individual release of the switch, blocking of a signal/the switch/a section, and activation of a platform emergency close button.

9. The portable safety terminal based method for processing rail transit resources according to claim 5 , wherein location information of the train is displayed on the portable safety terminal in various ways; and obtaining the location information of the train specifically comprises:
a) obtaining an active train location obtained by the train through a balise and speed and distance measuring equipment via long term evolution (LTE), wireless fidelity (Wifi), fifth-generation (5G), or waveguide tube wireless communication;
b) obtaining the location of the train via Beidou or a global positioning system (GPS); and
c) determining a kilometer post of the train on a track by manual confirmation.

10. A system for the portable safety terminal based method for processing rail transit resources according to claim 1 , comprising a portable safety terminal and a wayside controller, wherein the portable safety terminal communicates with the wayside controller via a wireless channel independent of a main system;
the portable safety terminal interacts with the wayside controller for controlling a train in a degradation mode; or the portable safety terminal interacts with wayside equipment for line maintenance, a status of the wayside equipment is obtained via the portable safety terminal, and a corresponding zone can be blocked, such that a lower track can be maintained.
