[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 the data of the vehicle-mounted reader through the vehicle-mounted antenna, send the data to the trackside application system, receive the trackside equipment information sent by the trackside application system, and send the trackside equipment information to the vehicle-mounted reader through the vehicle-mounted antenna; the active tag 13 is specifically used for:

[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 vehicle-mounted antenna. When the vehicle-mounted reader passes by, the trackside equipment information is reported to the vehicle-mounted 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 signal in the exit direction of the platform, in the middle of the platform inside the platform, in front and behind the turnout in the switch area, and in the transfer track area where the depot / depot enters the mainline area.

[0034] The trackside application system 14 is used to receive the data sent by the active tag, realize 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, thereby realizing the on-board processing of the exit route.

[0037] The platform door linkage realized through the vehicle application system 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 switches 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 to realize on-board control of the switch.

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

[0042] When a train passes by an active tag arranged 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 front and back order of all trains on the line, thereby 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 solution of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0046] like Figure 1As shown in the figure, the system mainly includes: on-board application system: used to realize functions such as train route handling and turnout switching, and can send relevant information to the on-board reader through the communication line; on-board reader: can store and delete information related to trackside equipment; on-board antenna: realize information transmission with ground tags; active tag: reads the information of the on-board reader through the on-board antenna and sends it to the trackside application system, the trackside application system sends the status of the trackside equipment to the active tag, and the active tag sends it to the on-board reader through the on-board antenna, and then informs the on-board application system; trackside application system: receives the information of the active tag, and realizes information collection and drive control of trackside signal machines, switch machines and other equipment. Related equipment is connected through communication lines.

[0047] Active tags require external communication cables for power supply and provide RS485 communication interface. Fixed information is pre-stored in active tags. Active tags and receiving antennas use RFID technology to achieve data transmission. When the vehicle-mounted reader passes, the active tag will report the trackside equipment information to the vehicle-mounted equipment, realizing ground-to-vehicle uplink communication. When the vehicle-mounted reader passes the active tag, it can also realize vehicle-to-ground downlink communication. The data received by the active tag is transmitted to the trackside application system through RS485 communication.

[0048] Storage information of the vehicle reader:

[0049] The on-board reader supports 1024kb of data storage, 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 layout principles of tags: 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 Turnout area: An active tag is set in front and behind the turnout, see Figure 4 Depot / parking lot entering the mainline area: Set an active tag in the transfer track area where the depot / parking lot enters the mainline. Figure 5 shown.

[0051] System functions such as Figure 1As shown, exit route processing: before the train passes an active tag, the driver inputs the green light command of the signal through the man-machine interface (MMI), and sends the command to the on-board reader through 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 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, thereby realizing the on-board processing of the exit route.

[0052] Platform door linkage: an active tag is set at the center of the platform. After the train stops at the platform, the driver inputs the platform door opening command through the man-machine interface (MMI), and sends the command to the on-board reader through 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 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 by the on-board equipment;

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

[0054] Train sequence management: The on-board reader on each train stores the unique ID of its own device. When the train passes the active tag arranged on the trackside, the active tag will record the ID information from the on-board reader and inform the trackside application system of the train ID information. The trackside application system will arrange and manage the front and back order of all trains on the line, thereby realizing the sequence management and tracking of online trains, making it convenient for operators to locate trains with communication failures in a timely manner and improve the efficiency of equipment repair.

[0055] Train positioning: The active tag will store its own location information in advance. 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, so as to realize the train's application for trackside resources, and the ground equipment's management of the online train sequence in line operation ensures the continuous tracking of train numbers, improves the availability of the signal system in the degraded mode, and reduces the impact of the interruption of the vehicle-to-ground wireless communication on the operation.

[0057] In summary, the embodiment of the present invention proposes a train resource management system in a degraded mode. When the wireless communication between the train and the ground is interrupted, the system can still be used to realize functions such as route handling, platform door linkage, switch operation, train sequence management, and train positioning. The autonomy of the on-board system is improved through driver operation when the wireless communication between the train and the ground 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 fault scenarios is greatly improved, reducing the impact on operations.
