[0025] System Example

[0026] According to an embodiment of the present invention, a train resource management system in a degraded mode is provided for use when train-ground wireless communication is interrupted.

[0029] The vehicle-mounted antenna 12 is connected to the vehicle-mounted reader and is used to realize information interaction between the vehicle-mounted reader and the ground active tag;

[0030] The active tag 13 is used to read data from the on-board reader via the on-board antenna and send the data to the trackside application system; receive trackside equipment information sent by the trackside application system and send the trackside equipment information to the on-board reader via the on-board antenna; the active tag 13 is specifically used to:

[0031] It is powered by an external communication cable and provides an RS485 communication interface. It pre-stores fixed information and uses RFID technology to transmit data with the on-board antenna. When the on-board reader passes by, the trackside equipment information is reported to the on-board reader, realizing ground-to-vehicle uplink communication and vehicle-to-ground downlink communication, and the received data is transmitted to the trackside application system via RS485 communication.

[0032] According to different control requirements, the active tag 13 is set at:

[0033] In front of the platform exit signal, in the middle of the platform inside the station, in front and behind the switch in the switch area, and in the transfer rail area where the depot / depot enters the mainline area.

[0034] The trackside application system 14 is configured to receive data sent by the active tag, implement information collection and drive control of the trackside equipment based on the data, and send the trackside equipment information to the active tag.

[0035] Specifically, the train route management implemented through the on-board application system includes:

[0036] Before a train passes an active tag, the on-board application system obtains the green light command from the signal and sends the green light command to the on-board reader. The on-board reader first informs the ground active tag of the train ID and route opening information through the on-board antenna. When the train passes the active tag, the active tag informs the trackside application equipment of the route opening information through the communication cable. After checking that there is no hostile route, the trackside application equipment drives the signal to green light, realizing the on-board processing of the exit route.

[0037] The platform door linkage achieved through the vehicle application system specifically includes:

[0038] After the train stops at the platform, the on-board application system obtains the platform door opening command and sends the platform door opening command to the on-board reader. The on-board reader informs the ground active tag of the train ID and the platform door opening command through the on-board antenna. When the train passes the active tag, the active tag informs the trackside application equipment of the platform door opening command through the communication cable. After checking that the platform door opening conditions are met, the trackside application equipment drives the platform door to open, thereby realizing the control of the platform door switch.

[0039] The specific implementation of turnout control through the on-board application system includes:

[0040] Before the train enters the switch area, the on-board application system obtains the switch switching command and sends the switch switching command to the on-board reader. The on-board reader informs the ground active tag of the train's on-board ID and the switch switching command through the on-board antenna. When the train passes the active tag, the active tag informs the trackside application equipment of the switch switching information and the occupancy information of the switch section through the communication cable. The trackside application equipment turns the switch to the corresponding position and locks the switch. When the train passes the switch section and passes the active tag behind the switch, the active tag obtains the train's on-board ID through the on-board antenna and informs the trackside application equipment through the communication cable. The trackside application equipment unlocks the switch in front of the active tag, and the switch switching command is reopened. Subsequent trains continue to requisition this switch, realizing on-board control of the switch.

[0041] The train sequence management implemented through the on-board application system includes:

[0042] When a train passes an active tag placed on the trackside, the active tag records its own device ID from the on-board reader and informs the trackside application system of its own device ID. The trackside application system arranges and manages the order of all trains on the line, realizing sequence management and tracking of online trains.

[0043] The specific implementation of train positioning through the on-board application system includes:

[0044] The active tag stores its own position information in advance. After the train passes the active tag, the on-board reader receives the position information sent from the active tag, and the train's own position is corrected based on the position information.

[0045] The above technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] like Figure 1As shown in the figure, the system mainly includes: an onboard application system: used to implement functions such as train route management and switch operation, and can send relevant information to an onboard reader via communication lines; an onboard reader: can store and delete information related to trackside equipment; an onboard antenna: realizes information transmission with ground tags; an active tag: reads the information from the onboard reader via the onboard antenna and sends it to the trackside application system, which transmits the status of the trackside equipment to the active tag, which sends it to the onboard reader via the onboard antenna, and then informs the onboard application system; the trackside application system: receives the information from the active tag and realizes information collection and drive control of trackside equipment such as signal machines and switch machines. The relevant equipment is connected by communication lines.

[0047] Active tags require an external communication cable for power and provide an RS485 communication interface. They contain pre-stored fixed information and utilize RFID technology to transmit data between the active tag and the receiving antenna. When a vehicle-mounted reader passes by, the active tag transmits information from the trackside equipment to the vehicle-mounted equipment, enabling ground-to-train uplink communication. When the vehicle-mounted reader passes by the active tag, vehicle-to-ground downlink communication is also possible. Data received by the active tag is transmitted to the trackside application system via RS485 communication.

[0048] Storage information of the vehicle reader:

[0049] The onboard reader supports 1024kb of data storage capacity, and the storage content includes: ID information of all online trains, its own equipment ID, and switch position status ID (positioning, reverse position).

[0050] Trackside tag placement principles: Platform exit direction: Set an active tag in front of the signal (such as the platform exit position and other positions in front of the signal), see Figure 2 Inside the platform: set up an active tag in the middle of the platform, see Figure 3 Switch area: an active tag is set in front and behind the switch, see Figure 4 As shown. Depot / parking lot entering the main line area: Set an active tag in the transfer track area where the depot / parking lot enters the main line. Figure 5 shown.

[0051] System functions such as Figure 1As shown, exit route processing: before a train passes an active tag, the driver inputs a green light command for the signal through the human-machine interface (MMI), and sends the command to the on-board reader via the on-board application system. The on-board reader first informs the ground active tag of the train ID and route opening information through the on-board antenna. When the train passes the active tag, the active tag notifies the trackside application equipment of the route opening information through the communication cable. After checking that there is no hostile route, the trackside application equipment drives the signal to green, thereby realizing the on-board processing of the exit route.

[0052] Platform door linkage: An active tag is installed at the center of the platform. After the train stops at the platform, the driver enters the platform door opening command through the human-machine interface (MMI). The command is sent to the on-board reader via the on-board application system. The on-board reader first informs the ground active tag of the train ID and the platform door opening command through the on-board antenna. When the train passes the active tag, the active tag notifies the trackside application equipment of the platform door opening command through the communication cable. After checking that the platform door opening conditions are met, the trackside application equipment drives the platform door to open, thereby realizing the control of the platform door opening by the on-board equipment.

[0053] Switch control: A pair of active tags are set in front of the switch. Before the train enters the switch area, the driver inputs the switch switching command (positioning, reverse position) through the human-machine interface (MMI) and sends the command to the on-board reader via the on-board application system. The on-board reader first informs the ground active tag of the train's onboard ID and switch switching command through the on-board antenna. When the train passes the active tag, the active tag informs the trackside application equipment of the switch switching information and the occupancy information of the switch section through the communication cable. The trackside application equipment moves the switch to the corresponding position and locks the switch. When the train passes the switch section and passes the active tag behind the switch, the active tag obtains the train's onboard ID through the on-board antenna and informs the trackside application equipment through the communication cable. The trackside application equipment unlocks the switch in front of the active tag, and the switch switching command can be reopened. Subsequent trains can continue to requisition this switch, thereby realizing on-board control of the switch.

[0054] Train sequence management: The onboard reader on each train stores its own unique ID. When a train passes an active tag placed on the trackside, the active tag records the ID information from the onboard reader and notifies the trackside application system of the train ID information. The trackside application system arranges and manages the order of all trains on the line, thereby realizing the sequence management and tracking of online trains, making it easier for operators to locate trains with communication failures in a timely manner and improving the efficiency of equipment repair.

[0055] Train positioning: The active tag will pre-store its own location information. After the train passes the active tag, it will receive the location information sent by the active transponder, thereby realizing the correction of the train's own position.

[0056] It can be seen from the above technical solutions that the technical solutions of the embodiments of the present invention are applied to the vehicle-to-vehicle communication signal system in the degraded mode. The vehicle-to-vehicle communication signal system in the main mode realizes data interaction between the train and the ground equipment through the vehicle-to-ground wireless communication technology. When the vehicle-to-ground wireless communication is interrupted, the corresponding American beacons can be set in the key areas of the line, and the relevant train information can be stored in advance, thereby realizing the train's application for trackside resources and the ground equipment's management of the online train sequence in line operation, ensuring the continuous tracking of train numbers, improving the availability of the signal system in the degraded mode, and reducing the impact of the interruption of the vehicle-to-ground wireless communication on operations.

[0057] In summary, the embodiment of the present invention proposes a train resource management system in a degraded mode. When the train-ground wireless communication is interrupted, the system can still be used to implement functions such as route handling, platform door linkage, switch operation, train sequence management, and train positioning. This improves the autonomy of the on-board system through driver operation when the train-ground wireless communication fails. For safety functions such as route handling and switch operation, the trackside application equipment will check the corresponding interlocking conditions and inform the driver whether the processing is successful through the signal display status, thereby effectively ensuring the safety of the train. The embodiment of the present invention ensures that when the main system is unavailable, the train can still achieve effective turnover and train tracking on the line. The availability of the system in failure scenarios is greatly improved, reducing the impact on operations.
