Description
Technical Field
The invention belongs to the field of rail transit, and particularly relates to a rail transit electronic map management method and a rail transit electronic map management system.
Background
The current common train operation control system comprises CTCS-0 level, CTCS-2 level and CTCS-3 level train control systems. The CTCS-0-level train control system monitors train operation based on a train operation monitoring and recording device (LKJ), an electronic map in the system is not transmitted in real time by ground equipment but is preset on a locomotive, if a line is modified, a complex reloading process needs to be carried out, and LKJ is extracted according to train coordinates when the electronic map is used, so that driving safety is endangered once errors occur.
The CTCS-2 level train control system depends heavily on a point type transponder, and an electronic map is preset in the transponder. When the train rolls over, the transponder sends electronic map to the mobile unit, therefore a large amount of transponders need to be laid to whole circuit, and the cost of circuit early-stage construction, later stage transformation upgrading and maintenance is high.
In the CTCS-3-level train control system, the driving permission transmitted from the ground center device to the in-vehicle device includes a part of the electronic map. Because the range of the line covered by each driving license is small, the electronic map cannot meet the requirement of the automatic driving function, and static information such as train grade switching and the like still needs to be sent to the train through the point type responder.
The ground center equipment in the CTCS-3 level train control system stores an electronic map in a certain area, and transmits the electronic map (only including static data such as line gradient, static speed limit and the like) in a driving permission range to the vehicle-mounted equipment along with driving permission in a wireless communication mode.
The complete train operation control system comprises vehicle-mounted equipment and ground equipment. Generally, a ground device sends an electronic map (i.e., fixed line data, such as line gradient, static speed limit, turnout information, static information of train control level switching, etc., in a train control system based on satellite positioning, including line longitude and latitude information, etc.) and dynamic driving signals or driving permission to a vehicle device, and the vehicle device monitors train operation according to the electronic map and the dynamic driving signals. The dynamic driving signal or the driving permission is dynamically generated in the driving process and is sent to the train in real time, the electronic map belongs to static data, and the line modification can cause change, so that the vehicle-mounted equipment is ensured to accurately and efficiently obtain the electronic map, the modification and maintenance cost is reduced, and the method is a subject worthy of research.

Fig. 1 is a schematic diagram showing the components of an electronic map management system according to an embodiment of the present invention. As shown in fig. 1, the electronic management system includes an in-vehicle apparatus, a first ground center apparatus, a second ground center apparatus, a wired communication system, and a wireless communication system. And wired communication connection is established between the first ground center equipment and the second ground center equipment, and wireless communication connection is established between the ground center equipment and the vehicle-mounted equipment.

After the train registration is completed, the first ground center device sends the number and version information of the local first electronic map to the train which has completed the registration.
After receiving the number and the version information of the first electronic map sent by the first ground center device, the vehicle-mounted device sends the number and the version information of the first electronic map stored in the vehicle-mounted device to the first ground center device.
And after comparing the number and version information of the local first electronic map with the number and version information of the first electronic map sent by the vehicle-mounted equipment, the first ground center equipment only sends electronic map blocks with different numbers and/or version information of the electronic map to the vehicle-mounted equipment.
And the vehicle-mounted equipment receives and updates the locally stored electronic map block and controls the train to run according to the latest electronic map.
When the train is about to run to the jurisdiction range of the second ground center equipment, the vehicle-mounted equipment calls the second ground center equipment through wireless communication, and communication session is established after the identity verification of the two parties is passed, so that the registration of the train to the second ground center equipment is completed.

Fig. 2 shows a schematic interaction flow diagram of the boundary electronic map according to the embodiment of the invention. As shown in fig. 2, the first ground center apparatus and the second ground center apparatus can both transmit and receive the boundary electronic map. At this time, if the first ground center device is the sender and the second ground center device is the responder, that is, the first ground center device sends the boundary electronic map information to the second ground center device, and after the second ground center device receives the information, the second ground center device replies confirmation information to the first ground center device, so that the first ground center device and the second ground center device complete the boundary electronic map information interaction.
Similarly, if the second ground center device is the sender, the first ground center device is the responder, so that the second ground center device sends the boundary electronic map information to the first ground center device, the first ground center device replies confirmation information to the second ground center device, and the boundary electronic map information interaction is completed, so that the electronic map sent to the vehicle-mounted device by the first ground center device and the second ground center device is continuously available.
The boundary electronic map information interaction between the first ground center equipment and the second ground center equipment ensures the continuity of the line, namely, the first electronic map jurisdiction of the first ground center equipment is in cross butt joint with the second electronic map jurisdiction of the second ground center equipment, and the train can continuously run in the electronic map jurisdictions of the first ground center equipment and the second ground center equipment.
Fig. 3 shows a boundary electronic map range diagram of an embodiment of the invention. As shown in fig. 3, the electronic map is an electronic map block unit, and each electronic map block includes three kinds of information, i.e., a number, a version, and specific content. The first ground center device stores the electronic map blocks within its map jurisdiction, and the second ground center device stores the electronic map blocks within its map jurisdiction. The first electronic map, the second electronic map and the boundary electronic map comprise a plurality of groups of electronic map blocks, numbers and version information of the electronic map blocks.
The boundary electronic map is an overlapped part of the first electronic map and the second electronic map.
Illustratively, the electronic map blocks stored by the first ground center device include n map blocks including "block 1_ 1" … …, "block 1_ m" and "block 1_ n", and in order to better embody the process of train movement, the n map blocks of "block 1_ 1" … …, "block 1_ m" and "block 1_ n" of the first ground center device are sequentially arranged in sequence. Similarly, the electronic map blocks stored by the second ground center device include s map blocks of "block 2_ 1", "block 2_ 2" … … and "block 2_ s", that is, "block 2_ 1", "block 2_ 2" … … and "block 2_ s" of the second ground center device are arranged in sequence. The first electronic map includes (n + 1) map blocks of "block 1_ 1" … …, "block 1_ m," "block 1_ n" and "block 2_ 1", the second electronic map includes (s + 1) map blocks of "block 1_ n," "block 2_1," "block 2_ 2" … … and "block 2_ s", and the boundary electronic map ranges from "block 1_ n" to "block 2_ 1". The first ground center device sends the block 1_ n to the second ground center device, and the second ground center device sends the block 2_1 to the first ground center device, so that the boundary electronic map interaction is completed.
After the train finishes registering to the second ground center equipment, the vehicle-mounted equipment receives the second electronic map and compares the boundary electronic map in the second electronic map with the boundary electronic map in the first electronic map. And if the boundary electronic map in the second electronic map is the same as the boundary electronic map in the first electronic map, switching the operation of the train controlled by the vehicle-mounted equipment according to the first electronic map into the operation of the train controlled according to the second electronic map.
For example, when the train is about to travel to the jurisdiction of the first ground center device, the train registration is completed with the first ground center device. The first ground center device sends the numbers and version information of the map blocks '1 _ 1' … …, '1 _ m', '1 _ n' and '2 _ 1' to the train, and the on-board device sends the numbers and version information of the corresponding map blocks stored in the first ground center device after receiving the numbers and version information. The first ground center device compares the number and version information of the map blocks "block 1_ 1" … …, "block 1_ m," "block 1_ n," and "block 2_ 1" stored locally with the number and version information of the corresponding map blocks sent by the vehicle-mounted device, and then only sends the electronic map blocks with different electronic map numbers and/or version information to the vehicle-mounted device. The vehicle-mounted equipment receives and updates the locally stored electronic map blocks, and controls the train to sequentially pass through the areas where the map blocks are located, namely the map block 1_1 … …, the map block 1_ m, the map block 1_ n and the map block 2_1 according to the latest electronic map.
When the train is about to run to the jurisdiction range of the second ground center equipment, the train registration is completed to the second ground center equipment, and the train logout is completed to the first ground center equipment. And the second ground center equipment transmits the numbers and version information of the map blocks 'block 1_ n', 'block 2_ 1', 'block 2_ 2' … … and 'block 2_ s' to the train, and after the vehicle-mounted equipment receives the numbers and version information, the vehicle-mounted equipment judges that the boundary electronic map blocks 'block 2_ 1' transmitted by the first ground center equipment and the second ground center equipment are the same, and then the vehicle-mounted equipment controls the train to operate according to the first electronic map and switches to control the train to operate according to the second electronic map. That is, the on-board device of the train switches to the second electronic map governed by the second ground center device, and the second electronic map includes the boundary electronic map blocks "block 1_ n", "block 2_ 1", and other electronic map blocks "block 2_ 2" … … and "block 2_ s".
When the first ground center equipment sends the first electronic map to the vehicle-mounted equipment, the map blocks in the first ground center equipment are used as units for sending, and therefore the map transmission speed is improved. And the transmission of the first electronic map is stored and transmitted through the first ground center equipment, so that the use of the transponder is reduced, and the construction and maintenance cost is reduced.
In fig. 1, if the number and version information of the electronic map block are the same, the first ground center device does not send the electronic map block to the vehicle-mounted device; the vehicle-mounted equipment controls the train to run according to the stored electronic map blocks:
the train operates from the first ground center device jurisdiction to the map jurisdiction of the second ground center device. When the train moves in the jurisdiction range of the first ground center equipment map, the first ground center equipment sends the first electronic map containing the boundary electronic map to the train, so that the train can conveniently run in the jurisdiction range of the first ground center equipment map. When the train runs into the area of the boundary electronic map overlapped by the first ground center equipment and the second ground center equipment, the vehicle-mounted equipment completes train registration to the second ground center equipment, and after the train is cancelled to the first ground center equipment, the vehicle-mounted equipment receives the second electronic map of the second ground center equipment and compares the boundary electronic map in the second electronic map with the boundary electronic map in the first electronic map. And if the boundary electronic map in the second electronic map is the same as the boundary electronic map in the first electronic map, the vehicle-mounted equipment controls the train to operate according to the first electronic map and switches to control the train to operate according to the second electronic map. The train can then travel from the first electronic map range of the first ground center to the second electronic map range of the second ground center, and likewise the train can travel from the second electronic map range of the second ground center to the first electronic map range of the first ground center.
If the numbers and/or version information of the electronic map blocks are different, the first ground center equipment sends the different electronic map blocks to the vehicle-mounted equipment; the vehicle-mounted equipment receives the different electronic map blocks, updates the corresponding locally stored electronic map blocks and controls the train to run according to the latest electronic map:
the train operates from a first ground center device map jurisdiction to a second ground center device map jurisdiction. When the ground center equipment electronic map information is updated, the first ground center equipment and the second ground center equipment should interact with the boundary electronic map, so that the updated first electronic map and the second electronic map are obtained. And then the vehicle-mounted equipment compares whether the boundary electronic map of the first ground center equipment is consistent with the boundary electronic map of the second ground center equipment. If the two maps are consistent, the train can run from the jurisdiction range of the first ground center equipment map to the jurisdiction range of the second ground center equipment map; if not, the train cannot run from the first ground center equipment map jurisdiction to the second ground center equipment map jurisdiction.
For example, when the on-board unit of the train operates using the electronic map of the first version of the first ground center unit, the electronic map of the first ground center unit is updated to the second version, and the first ground center sends the updated electronic map different from the first version to the on-board unit of the train, so that the train can conveniently acquire and use the electronic map of the first ground center unit in real time.
And the first ground center equipment and the second ground center equipment respectively store the boundary electronic map.
When the first ground center device and the second ground center device are restarted or communication is interrupted, the first ground center device deletes the boundary electronic map sent by the second ground center device, and the second ground center device deletes the boundary electronic map sent by the first ground center device. And when the first ground center equipment and the second ground center equipment are started or the communication is restored again, the first ground center equipment and the second ground center equipment interact the boundary electronic map again.
Before the first ground center device is restarted or communicated with the second ground center device in a communication mode, the boundary electronic map from the second ground center device in the first ground center device may change, and if the first ground center device continues to use the conventional boundary electronic map, the boundary electronic map error may occur, so that the normal operation of the train is influenced. When the first ground center device is started to communicate with the second ground center device and is interrupted and then recovered, the first ground center device and the second ground center device need to update the boundary electronic map information of each other, so that the map consistency between the first ground center device and the second ground center device is ensured.
The invention also comprises a rail transit electronic map management system,
the system comprises first ground center equipment, second ground center equipment and vehicle-mounted equipment;
the first ground center device is used for sending a first electronic map containing a boundary electronic map.
And the second ground center equipment is used for sending a second electronic map containing the boundary electronic map.
And the vehicle-mounted equipment is used for receiving and controlling the train to operate according to the first electronic map or the second electronic map.
The first ground center equipment is also used for respectively comparing the electronic map block number and the version information sent by the vehicle-mounted equipment with the electronic map block number and the version information stored in the first ground center equipment;
if the numbers and/or version information of the electronic map blocks are different, the first ground center equipment sends the different electronic map blocks to the vehicle-mounted equipment;
the vehicle-mounted equipment receives the different electronic map blocks, updates the corresponding locally stored electronic map blocks and controls the train to run according to the latest electronic map;
if the number and the version information of the electronic map block are the same, the first ground center equipment does not send the electronic map block to the vehicle-mounted equipment;
and the vehicle-mounted equipment controls the train to run according to the stored electronic map.
The invention stores and transmits the electronic map by using the first ground center equipment and performs centralized management on the electronic map, thereby greatly reducing the use of the transponder and reducing the construction and maintenance cost. The first ground center equipment can send the electronic map in the map area range to the vehicle-mounted equipment in a short time, and the vehicle-mounted equipment is convenient to use. The first ground center equipment and the second ground center equipment mutually transmit the boundary electronic map, so that the maintenance cost is reduced compared with a static overlapped configuration mode of the boundary electronic map, the continuity of the electronic maps of the first ground center equipment and the second ground center equipment is ensured, only map blocks with inconsistent electronic map versions are sent to the vehicle-mounted equipment, and the wireless bandwidth resource is saved.
