[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] First, a further detailed description will be made of the technical background targeted by the embodiments of the present invention.

[0045] This embodiment mainly targets the application scenario of rail transit and is mainly used to detect the occupancy status of the logical sections of trains. Currently, the detection methods for the occupancy status of logical sections are mainly divided into two types: the "AND idle" method and the "OR occupied" method.

[0046] In the urban rail CBTC (Communication Based Train Control) system, when the ZC (Zone Controller) subsystem determines the occupancy status of the logical section, it uses the "AND idle" method, that is, when the physical section reported by the interlocking system is idle, and it is calculated based on the position information reported by the train that the smallest block section (also known as the block section) included in this physical section is idle, then the occupancy status of the logical section included in this physical section is idle. In other cases, the occupancy status of the logical section is determined to be occupied.

[0047] In the CTCS-3 train control system of main railways, when the RBC (Radio Block Center) subsystem determines the occupancy status of the logical section, it uses the "OR occupied" method, that is, when the physical section reported by the interlocking system is occupied, or it is calculated based on the position information reported by the train that the logical section included in this physical section is occupied, then the occupancy status of the logical section included in this physical section is occupied. In other cases, the occupancy status of the logical section is determined to be idle.

[0048] For the above two common detection methods for the occupancy status of logical sections, due to incomplete consideration of factors, the detection results are not accurate enough in some scenarios. At the same time, due to the inability to accurately locate the occupied position of the train, problems such as incorrect signal light turning off or increased train tracking intervals are likely to occur, and the safety of the detection process is low.

[0049] The following will further illustrate the detection method, device, train, and electronic device for the occupancy status of the logical section provided by the present invention in conjunction with the embodiments shown in the attached Figure 1 to Figure 5 The embodiments shown are used for further illustration.

[0050] Figure 1The following shows the method for detecting the occupancy status of a logical section provided by an embodiment of the present invention. The method includes:

[0051] Step 101: Obtain the occupancy status of a physical section, the position information of the train, the monitoring mode of the train, the front and rear end suspicious mark information, and the turnout condition of the logical section;

[0052] Step 102: Determine the occupancy status of the smallest block section in the physical section based on the monitoring mode of the train, the occupancy status of the physical section, the position information of the train, and the front and rear end suspicious mark information;

[0053] Step 103: Detect the occupancy status of the logical section based on at least one of the monitoring mode of the train, the turnout condition of the logical section, the occupancy status of the physical section, and the occupancy status of the smallest block section.

[0054] In this embodiment, the monitoring mode of the train, the position information of the train, and the front and rear end suspicious mark information can be reported by the train, and the occupancy status of the physical section can be reported by the interlocking system. The occupancy status of the physical section in this embodiment mainly involves two situations: occupied and idle of the physical section.

[0055] The monitoring mode of the train mainly involves the full monitoring mode and the guiding mode. When the on-board equipment on the train has all the basic data required for train control, including train data, movement authority, and track data, etc., the on-board equipment automatically enters the full monitoring mode; when the guiding signal or the departure signal is open and the front end of the train is far from the departure signal (for example, more than 250 m) at departure, it enters the guiding mode. The on-board equipment generates a target distance continuous speed control curve and displays the running speed, permitted speed, target speed, and target distance of the train through the DMI. The on-board equipment monitors the train operation according to a fixed limit, and the driver is responsible for checking the track occupancy status.

[0056] The occupancy status of the smallest block section mainly involves three situations: occupied by a communication vehicle (also known as AT occupancy), occupied by a non-communication vehicle (also known as UT occupancy), and idle. The turnout condition of the logical section mainly reflects whether there is a turnout in the logical section.

[0057] In this embodiment, by introducing the comprehensive analysis of the monitoring mode of the train, the front and rear end suspicious mark information, the turnout condition of the logical section, the occupancy status of the physical section, and the position information of the train, the occupancy status of the logical section is detected. Since the data for the determination basis is more comprehensive, the accuracy and reliability of the detection result are effectively improved.

[0058] In an exemplary embodiment, based on the monitoring mode of the train, the occupancy status of the physical section, the position information of the train, and the front and rear end suspicious mark information, to determine the occupancy status of the smallest block section in the physical section, it may specifically include:

[0059] When the monitoring mode of the train is the full monitoring mode or the guiding mode and the position information of the train is unknown, determine the occupancy status of the minimum block section based on the occupancy status of the physical section;

[0060] When the monitoring mode of the train is the full monitoring mode or the guiding mode, the position information of the train includes the minimum block section, and the front and rear end suspicious mark information indicates that there are no front and rear end suspicious marks, the occupancy status of the minimum block section is occupied by the communication vehicle;

[0061] When the monitoring mode of the train is the full monitoring mode or the guiding mode, the position information of the train includes the minimum block section, and the front and rear end suspicious mark information indicates that there is a front end suspicious mark or a rear end suspicious mark, the occupancy status of the minimum block section is not occupied by the communication vehicle;

[0062] When the monitoring mode of the train is neither the full monitoring mode nor the guiding mode, the occupancy status of the minimum block section is not occupied by the communication vehicle.

[0063] In this embodiment, based on the monitoring mode of the train, the occupancy status of the physical section, the position information of the train, and the front and rear end suspicious mark information, comprehensively analyze the occupancy status of the minimum block section. First, the detection direction of the occupancy status of the minimum block section can be determined according to the monitoring mode of the train. Specifically, if the monitoring mode of the train is neither the full monitoring mode nor the guiding mode, regardless of other conditions, the occupancy status of the minimum block section is UT occupancy, that is, not occupied by the communication vehicle;

[0064] If the monitoring mode of the train is the full monitoring mode or the guiding mode, further determination is required based on other relevant information. Specifically, if the train does not report its position (i.e., the position information is unknown), regardless of the front and rear end suspicious mark information, the occupancy status of the minimum block section can be directly determined by the occupancy status of the physical section;

[0065] If the train reports its position (i.e., the position information can be obtained), the position information includes the current minimum block section to be detected, and there are no front and rear end suspicious marks (i.e., there are no front and rear end suspicious marks), regardless of the occupancy status of the physical section, the occupancy status of the minimum block section is AT occupancy, that is, occupied by the communication vehicle;

[0066] If the train reports its position, the position information includes the current minimum block section to be detected, and it is determined that there is a front end suspicious mark or a rear end suspicious mark based on whether the train head or the train tail occupies the current minimum block section, regardless of the occupancy status of the physical section, the occupancy status of the minimum block section is UT occupancy, that is, not occupied by the communication vehicle.

[0067] Based on the above process, it is possible to comprehensively analyze various data and accurately detect the occupancy status of the smallest block section within the physical section.

[0068] Furthermore, determining the occupancy status of the smallest block section based on the occupancy status of the physical section may specifically include:

[0069] If the occupancy status of the physical section is that the physical section is occupied, then the occupancy status of the smallest block section is occupied by a non - communicating vehicle;

[0070] If the occupancy status of the physical section is that the physical section is idle, then the occupancy status of the smallest block section is idle.

[0071] This embodiment is directed to the situation where the monitoring mode of the train is the full monitoring mode or the guiding mode and the position information of the train is unknown. In this case, the occupancy status of the smallest block section can be determined by the occupancy status of the physical section. If the physical section is occupied, then the occupancy status of the smallest block section is occupied by a UT, that is, occupied by a non - communicating vehicle; if the physical section is idle, then the smallest block section is also in an idle state.

[0072] In an exemplary embodiment, based on at least one of the monitoring mode of the train, the turnout condition of the logical section, the occupancy status of the physical section, and the occupancy status of the smallest block section, the occupancy status of the logical section is detected. Specifically, it may include:

[0073] When the monitoring mode of the train is neither the full monitoring mode nor the guiding mode, the occupancy status of the logical section is occupied by a non - communicating vehicle;

[0074] When the monitoring mode of the train is the full monitoring mode or the guiding mode, based on the turnout condition of the logical section, the occupancy status of the physical section, and the occupancy status of the smallest block section, the occupancy status of the logical section is determined.

[0075] Regarding the occupancy status of the logical section, it is also possible to first determine the detection direction based on the monitoring mode of the train. If the monitoring mode of the train is neither the full monitoring mode nor the guiding mode, regardless of the occupancy status of the physical section and the smallest block section, the occupancy status of the logical section is occupied by a non - communicating vehicle;

[0076] If the monitoring mode of the train is the full monitoring mode or the guiding mode, then it is necessary to further determine the occupancy status of the logical section according to the turnout condition of the logical section, the occupancy status of the physical section, and the occupancy status of the smallest block section.

[0077] Furthermore, based on the turnout condition of the logical section, the occupancy status of the physical section, and the occupancy status of the smallest block section, determining the occupancy status of the logical section may specifically include:

[0078] If the turnout condition of the logical section is without turnout, determine the occupancy status of the logical section based on the occupancy status of the minimum block section;

[0079] If the turnout condition of the logical section is with turnout, determine the occupancy status of the logical section based on the occupancy status of the physical section and the occupancy status of the minimum block section.

[0080] This embodiment mainly aims at the situation where the train monitoring mode is the full monitoring mode or the guiding mode. In this situation, the turnout condition of the logical section can be further judged. If the turnout condition of the logical section is without turnout, the occupancy status of the logical section can be directly determined based on the occupancy status of the minimum block section; if the turnout condition of the logical section is with turnout, the occupancy status of the logical section can be determined based on the occupancy status of the physical section and the occupancy status of the minimum block section.

[0081] Furthermore, determining the occupancy status of the logical section based on the occupancy status of the minimum block section may specifically include:

[0082] If the occupancy status of the minimum block section is occupied by a communication vehicle, the occupancy status of the logical section is occupied by a communication vehicle;

[0083] If the occupancy status of the minimum block section is not occupied by a communication vehicle, the occupancy status of the logical section is not occupied by a communication vehicle;

[0084] If the occupancy status of the minimum block section is idle, the occupancy status of the logical section is idle.

[0085] This embodiment is aimed at the situation where the turnout condition of the logical section is without turnout. In this situation, the occupancy status of the logical section is the same as the occupancy status of the minimum block section, mainly involving three states: occupied by a communication vehicle, not occupied by a communication vehicle, and idle.

[0086] Furthermore, determining the occupancy status of the logical section based on the occupancy status of the physical section and the occupancy status of the minimum block section may specifically include:

[0087] If the occupancy status of the physical section is occupied by the physical section and the occupancy status of at least one minimum block section is not occupied by a communication vehicle, the occupancy status of the logical section is not occupied by a communication vehicle;

[0088] If the occupancy status of the physical section is occupied by the physical section and the occupancy status of at least one minimum block section is occupied by a communication vehicle, the occupancy status of the logical section is occupied by a communication vehicle;

[0089] If the occupancy status of the physical section is idle of the physical section and the occupancy status of all minimum block sections are idle, the occupancy status of the logical section is idle.

[0090] This embodiment mainly focuses on the situation where there is a turnout in the logical section. In this case, it is necessary to comprehensively judge the occupancy status of the logical section based on the occupancy status of the physical section and the occupancy status of each minimum block section in the physical section.

[0091] In the actual application process, within one cycle, under various train monitoring modes, the occupancy status of the physical section, the position information of the train, and the occupancy status of the block section (i.e., the minimum block section), the occupancy status of the logical section can be seen in Table 1 below.

[0092] Table 1 Various situations of the occupancy status of the logical section

[0093]

[0094] This embodiment considers the influencing factors for detecting the occupancy status of the logical section from multiple aspects and angles. Based on the occupancy status of each physical section reported by the interlocking system, the position information reported by the train, the train monitoring mode, and the front and rear end suspicious mark information, etc., the occupancy status of the minimum block section is calculated. Then, according to the inclusion relationship between the minimum block section and the logical section, the occupancy status of the logical section is detected. Specifically, it is based on at least one of the train monitoring mode, the turnout status of the logical section, the occupancy status of the physical section, and the occupancy status of the minimum block section to detect the occupancy status of the logical section.

[0095] Figure 2 and Figure 3 respectively show the inclusion relationship between the logical section and the minimum block section. Figure 2 shows the positions of the logical section D2G and the two minimum block sections BK_D2G1 and BK_D2G2 corresponding to this logical section, the positions of the logical section D3G and the two minimum block sections BK_D3G1 and BK_D3G2 corresponding to this logical section, the positions of the logical section C2G and the two minimum block sections BK_C2G2 and BK_C2G1 corresponding to this logical section, and the positions of the logical section C3G and the two minimum block sections BK_C3G2 and BK_C3G1 corresponding to this logical section.

[0096] Figure 3Shows the positions of the logical section 20-1DG-A and its corresponding minimum block section BK_20-1DG-A, the logical section 20-1DG-B and its corresponding minimum block section BK_20-1DG-B, the logical section 20-1DG-C and its corresponding minimum block section BK_20-1DG-C, the logical section 20-3DG-C and its corresponding minimum block section BK_20-3DG-C, the logical section 20-3DG-B and its corresponding minimum block section BK_20-3DG-B, and the logical section 20-3DG-A and its corresponding minimum block section BK_20-3DG-A.

[0097] In the actual application process, when the interlocking system reports the occupancy of the physical section within the signal-protected route, and at this time the train is outside the signal, according to the position information reported by the train and the monitoring mode, it can be known that the minimum block section within this physical section is idle. At this time, based on the occupancy status of the minimum block section, it can be comprehensively judged that the logical section is idle. Since the position where the train is pressing can be accurately located, the situation of the signal being wrongly turned off will not occur, effectively solving the problem of being unable to accurately judge the occupancy status of the logical section in the above scenario, and realizing accurate and reliable detection of the occupancy status of the logical section.

[0098] The detection device for the occupancy status of the logical section provided by the present invention will be described below. The detection device for the occupancy status of the logical section described below can be mutually corresponding and referred to the detection method for the occupancy status of the logical section described above.

[0105] When the monitoring mode of the train is the full monitoring mode or the guiding mode, the position information of the train includes the minimum block section, and the suspicious mark information at the front and rear ends indicates that there are no suspicious marks at both the front and rear ends, the occupancy status of the minimum block section is occupied by the communication vehicle;

[0106] When the monitoring mode of the train is the full monitoring mode or the guiding mode, the position information of the train includes the minimum block section, and the suspicious mark information at the front and rear ends indicates that there is a front-end suspicious mark or a rear-end suspicious mark, the occupancy status of the minimum block section is not occupied by the communication vehicle;

[0107] When the monitoring mode of the train is not the full monitoring mode and not the guiding mode, the occupancy status of the minimum block section is not occupied by the communication vehicle.

[0108] Further, the first processing module 402 can specifically determine the occupancy status of the minimum block section based on the occupancy status of the physical section through the following process:

[0109] If the occupancy status of the physical section is that the physical section is occupied, the occupancy status of the minimum block section is not occupied by the communication vehicle;

[0110] If the occupancy status of the physical section is that the physical section is idle, the occupancy status of the minimum block section is idle.

[0111] In an exemplary embodiment, the second processing module 403 can specifically be used for:

[0114] Further, the second processing module 403 can specifically determine the occupancy status of the logical section based on the turnout condition of the logical section, the occupancy status of the physical section, and the occupancy status of the minimum block section through the following process:

[0115] If the turnout condition of the logical section is that there is no turnout, determine the occupancy status of the logical section based on the occupancy status of the minimum block section;

[0116] If the turnout condition of the logical section is that there is a turnout, the occupancy status of the logical section is determined based on the occupancy status of the physical section and the occupancy status of the minimum block section.

[0117] Further, the second processing module 403 can specifically implement determining the occupancy status of the logical section based on the occupancy status of the minimum block section through the following process:

[0123] If the occupancy status of the physical section is occupied by the physical section and the occupancy status of at least one minimum block section is occupied by a communication vehicle, the occupancy status of the logical section is occupied by a communication vehicle;
