Abstract
Description
Technical Field
[0001] This invention relates to the field of rail transit testing technology, and in particular to a heavy-haul train simulation ATP model and a heavy-haul train simulation testing system. Background Technology
[0002] Heavy-haul railways refer to railways with high total train weight, high traffic density, and high transport capacity, primarily used for transporting large raw material goods. Since the construction and operation of the Datong-Qinhuangdao Railway in 1983, China's railways have developed a complete heavy-haul transportation technology system with independent intellectual property rights. However, in recent years, the development of heavy-haul railways has failed to meet the ever-increasing demands for high safety in terms of transportation, and its transport capacity has also failed to meet the growing capacity and volume requirements of my country's heavy-haul railways.
[0003] To address the aforementioned issues, a high-density automatic operation control technology for heavy-haul freight trains using an ad hoc network has been proposed. This ad hoc network technology enables information exchange between trains through vehicle-to-vehicle communication, grouping multiple physical trains into a train group. Ground equipment controls the train group, effectively shortening train tracking intervals, reducing the difficulties of multi-level synchronous operation, and lowering transportation costs such as labor and energy consumption.

[0097] GCC is an abbreviation for Group Control Center. ATP is an abbreviation for Automatic Train Protection.
[0098] S102: When the following train's ATP is a real ATP, the train status information of the following train is sent to the preceding train according to the real ATP configuration information and the group command;
[0099] Alternatively, when the following train's ATP is a simulated ATP, the train status information of the following train is sent to the preceding train according to the configuration information of the simulation database and the group command.
[0100] The train status information includes the train's ID. After the preceding train obtains the train's ID, it can compare it with the following train's ID in the received group command. When the two IDs match, it means that the following train is the one that needs to be connected.
[0101] S103: Based on the group command and the train status information, establish a train formation connection between the following train and the preceding train.
[0102] In the simulation test system for the heavy-haul train group control system, a simulated ATP (Automatic Train Protection) is established in the simulation support layer module; the physical interface layer module in the test system can also connect to a real ATP. The test environment consists of the simulation support layer module and the physical equipment.

Figure 3 As shown, the ATP of the preceding train determines whether to detach from the following train based on the group command issued by the GCC.
[0117] When the preceding vehicle's ATP determines whether to de-encode or de-encode the preceding vehicle based on the group command...
[0118] The preceding ATP sends a decompilation message to the following ATP;
[0119] Based on the received decoding message, the rear ATP triggers the rear ATP to send a disconnection confirmation message to the front ATP.
[0120] Based on the disconnection confirmation message, the train group connection between the rear train and the front train is disconnected, and the train grouping is completed.
[0121] In this embodiment, the preceding ATP sends decoding messages to the following ATP at a first preset frequency. In this embodiment, the first preset frequency is one decoding message sent per second.
[0122] The following ATP vehicle sends a disconnection confirmation message to the preceding ATP vehicle at a second preset frequency. In this embodiment, the second preset frequency is three confirmation messages sent per second.

Within the simulation host, the vehicle-to-ground information calculation module manages ground trackside equipment information and calculates train position information in real time. When a group of trains is running on the track, the vehicle-to-ground information calculation module calculates and updates the train position, sending relevant trackside information (track circuits, transponder messages, etc.) to the physical ATP or simulated ATP system via the train model.
