[0063] See attached Figure 1 , the method of the present invention comprises:

[0064] S1. Acquire track circuit status information, convert the track circuit status information into physical section status information, and combine it with train position information to form logical section information;

[0071] Wherein, when the interlocking logic unit determines that the communication with the electronic module is interrupted, the state of the interlocking internal section corresponding to the fault is set to an illegal value, and the train operation unlocking logic is no longer executed in the section;

[0072] Wherein, when the interlocking logic unit determines that the group control center handles a fault, the state of the interlocking internal section corresponding to the fault is set to an illegal value, and the section no longer executes the train operation unlocking logic;

[0073] Among them, when the communication between the interlocking logic unit and the group control center is interrupted, the physical section status information is used to form the interlocking internal section status information to identify the train running unlocking interlocking approach;

[0074] Wherein, the method is applied to a heavy-load group operation control system.

[0075] Specifically,

[0076] 1. Acquire track circuit status information, convert the track circuit status information into physical section status information, and combine it with train position information to form logical section information.

[0077] Acquire track circuit status information, convert the track circuit status information into physical section status information, and combine it with train position information to form logical section information, including:

[0078] The track circuit status information is obtained through the electronic module and sent to the interlocking logic unit;

[0079] The interlocking logic unit converts the track circuit status information into physical section status information and sends it to the group control center;

[0080] The group control center forms logical section information based on the physical section status information and train position information, and sends it to the interlocking logic unit.

[0081] 1. The electronic module obtains the track circuit status information and sends it to the interlocking logic unit.

[0082] In this embodiment, the occupation and idle status of the track circuit is obtained through the electronic module in the track circuit and sent to the CBI interlocking logic unit.

[0083] The electronic modules in each track circuit in the computer interlocking (CBI) are connected to the outdoor rails respectively to detect the occupation and idle status of the corresponding track circuit; the electronic modules send the collected track circuit occupation and idle status as track circuit status information to the CBI interlocking logic unit through the interlocking internal control network.

[0084] 2. The track circuit status information is converted into physical section status information and sent to the group control center (GCC).

[0085] In this embodiment, the interlocking logic unit converts the track circuit status information collected by the electronic module into physical section status information according to the preset group control center (GCC)-computer interlocking (CBI) interface specification, and sends it to the group control center (GCC).

[0086] The physical segment status information is: "occupied" or "free".

[0087] 3. Based on the physical section status information and combined with the train position information, logical section information is formed and sent to the interlocking logic unit.

[0088] The group control center forms logical section information based on the physical section status information and train position information, and sends it to the interlocking logic unit.

[0089] In this embodiment, the group control center converts the physical section status information and train position information into logical section information according to the preset group control center (GCC)-computer interlocking (CBI) interface specification, and sends the logical section status information to the computer interlocking logic unit.

[0090] The logical segment status information is: "communication vehicle occupied", "non-communication vehicle occupied" or "idle".

[0091] 2. Based on the logical section status information, the interlocking internal section status information is formed to identify the train running unlocking interlocking route.

[0092] The computer interlocking logic unit forms the interlocking internal section status information based on the logical section status information, which is used to identify the interlocking route for train operation unlocking.

[0093] The computer interlocking logic unit receives the logic section status information to form the interlocking internal section status information, and identifies the train running unlocking interlocking route.

[0094] In this embodiment, when the computer interlocking logic unit identifies the train running unlocking interlock, it can adopt the three-point inspection logic commonly used in the industry.

[0095] 3. When there is a fault in the unlocking interlocking route, abnormal protection is executed.

[0096] When the interlocking logic unit determines that there is a fault in the unlocking interlocking route, the state of the interlocking internal section corresponding to the fault is set to an illegal value, and the section no longer executes the train operation unlocking logic.

[0097] 1. When the interlocking logic unit determines that the electronic module is faulty, the state of the interlocking internal section corresponding to the fault is set to an illegal value, and the section no longer executes the train operation unlocking logic.

[0098] When the interlocking logic unit receives a fault information report sent by the electronic module, it determines that the electronic module is faulty.

[0099] In this embodiment, when the interlocking logic unit communicates with the electronic module in the track circuit, the electronic module sends 2 bits of information for each section to indicate the state of the corresponding track circuit, including: 01, indicating occupation; 00, indicating failure; 11 indicating idle. When the electronic module in the track circuit detects a fault in itself, it sends 00 information to the interlocking logic unit. When the interlocking logic unit receives 00 information, it determines that the corresponding electronic module is faulty, sets the interlocking internal section state of the section to an illegal value, and the section no longer executes the train operation unlocking logic. When the section becomes idle, the interlocking logic unit does not unlock the section.

[0100] In this embodiment, without performing abnormal protection, when the electronic module of the track circuit fails, the corresponding section status is "occupied", indicating that the train has entered the section; when the electronic module of the track circuit fails and there is no train in the section, the corresponding section status is "idle", indicating that the train has left the section. If multiple track circuit electronic modules fail and recover, the track circuit status information sent by the electronic module may be the same as the timing of the train occupying the route section and clearing the route section, which may lead to the incorrect unlocking of the interlocking route.

[0101] 2. When the interlocking logic unit determines that the communication with the electronic module is interrupted, the state of the interlocking internal section corresponding to the fault is set to an illegal value, and the section no longer executes the train operation unlocking logic.

[0102] When the interlocking logic unit does not receive the electronic module data within a preset time, it is determined that the communication with the electronic module is interrupted.

[0103] In this embodiment, the interlocking logic unit uses the RSSP-I communication protocol widely used in the industry to communicate with the electronic module in the track circuit, and the communication delay time can be preset to 3 seconds. When the interlocking logic unit does not receive valid electronic module data within 3 seconds, it is determined that the communication with the corresponding electronic module is interrupted.

[0104] When the interlocking logic unit determines that the communication with the electronic module is interrupted, the state of the internal section of the interlocking is set to an illegal value, and the train operation unlocking logic is no longer executed in this section.

[0105] 3. When the interlocking logic unit determines that the group control center handles a fault, the state of the interlocking internal section corresponding to the fault is set to an illegal value, and the section no longer executes the train operation unlocking logic.

[0106] When the interlocking logic unit checks that the group control center has not received the corresponding logic section information within the preset communication delay tolerance time, it is determined that the group control center has processed a fault.

[0107] In this embodiment, after the interlocking logic unit sends the physical section status information to the group control center (GCC) based on the track circuit status information collected by the electronic module of the track circuit, if the time for receiving the corresponding logical section status information sent by the group control center exceeds the communication delay tolerance time, it is judged that the group control center has processed a fault, and the internal section status of the interlocking is set to illegal, and the section no longer executes the train operation unlocking logic.

[0108] In this embodiment, it is assumed that after the electronic module detects that a certain section is occupied, it sends the track circuit status information "occupied" to the interlocking logic unit; after receiving the "occupied" status, the interlocking logic unit checks the received GCC logic section status information. If the information received by the GCC shows that the section status is "idle", it means that there is an inconsistency between the information; if the correct GCC logic section status information is not received within the preset communication delay tolerance time, that is, "idle" is always received, it is judged that the GCC processing logic section status is abnormal, and the interlocking internal section status corresponding to the fault is set to an illegal value, and the section no longer executes the train operation unlocking logic.

[0109] In this embodiment, without performing abnormal protection, when the interlocking logic unit receives the GCC logical segment status, if a serious abnormality is found by comparing the physical segment status information collected and sent by the interlocking side track, and the interlocking side does not perform protection, there may be risks in fully trusting the GCC equipment in this case.

[0110] In this embodiment, when the communication between the interlocking logic unit and the group control center is interrupted, the physical section status can be used to form the interlocking internal section status information to identify the train running unlocking interlocking route.

[0111] Under normal circumstances, interlocking preferentially adopts the segment status processing path of "track circuit status information - physical segment status information - logical segment information - interlocking internal segment status information". This processing has two sources of information, one is the information of the track circuit module, and the other is the information of the train position. More information sources can improve the reliability and safety of the track segment status module.

[0112] However, when the communication between the interlocking logic unit and the group control center is interrupted, the physical section status can be directly used to form the interlocking internal section status information, and the train operation unlocking interlocking route can be identified based on the information of the track circuit module to ensure that the train operation can still maintain safety and stability during the communication interruption.

[0113] The computer interlocking track section abnormality protection method of this embodiment can be applied to the heavy-load group operation control system. The heavy-load group operation control system is an advanced dispatching and control system specifically for heavy-load railway transportation, mainly used to improve the efficiency and safety of bulk cargo transportation.

[0114] In this embodiment, the interlocking logic unit converts the track circuit status information collected by the electronic module into physical section status information in accordance with the "Group Control Center (GCC)-Computer Interlocking (CBI) Interface Specification for Heavy-Load Train Group Operation Control System" and sends it to the group control center (GCC); the group control center converts the physical section status information and train position information into logical section information in accordance with the "Group Control Center (GCC)-Computer Interlocking (CBI) Interface Specification for Heavy-Load Train Group Operation Control System", and sends the logical section status information to the computer interlocking logic unit.

[0115] The definition of the physical section status message packet sent by CBI to GCC in the "Heavy-load Train Group Operation Control System Group Control Center (GCC)-Computer Interlocking (CBI) Interface Specification" is shown in Table 1.

Figure 3 In the computer interlocking (CBI), each track circuit is provided with an electronic module: track circuit 1 electronic module, track circuit 2 electronic module, ..., track circuit n electronic module. Each electronic module is connected to the outdoor rail to detect the occupation and idleness of the track circuit. The electronic module sends the occupation and idleness of the track circuit to the CBI interlocking logic unit through the interlocking internal control network.

[0128] The interlocking logic unit converts the occupied and idle status of the track circuit electronic module into a physical section status message: "occupied" or "idle", and sends it to the group control center (GCC). The group control center (GCC) forms logical section information based on the physical section status message and train position information: "communication car occupied", "non-communication car occupied" or "idle", and sends the logical section status information to the interlocking logic unit.
