Description

Technical Field

[0001] The present invention belongs to the field of railway control technology, and in particular, relates to a method, system, device and medium for controlling section coding within a terminal approach of a field connection. Background Art

[0002] The two stations in a field-linked relationship are controlled by different interlocking systems. The field-linked TCC (Train Control Center) obtains the approach information on its own side from the interlocking equipment. The TCC equipment at the station at the starting end of the field-linked approach needs to obtain the approach information at the end of the field-linked approach through inter-station communication to realize functions such as sending the external active balise message of the signal at the starting end of the field-linked approach, speed limit reduction of the starting end signal, and coding of the approach approach section and the track section within the route. The equipment of the TCC at the station at the end of the field-linked approach realizes the coding of the track section within the route at the end of the field-linked approach according to the approach conditions sent by the interlocking equipment on its own side.

[0003] For ZPW-2000 series track circuits, different carrier frequencies are required to be sent in adjacent track sections and adjacent lines. For cross-line operations, frequency switching codes are used to announce frequency switching. When the train enters the turnout, the frequency switching code is sent. After the train receives the frequency switching code, it starts to receive the corresponding carrier frequency. The carrier frequencies of track circuits should be arranged alternately. The alternating arrangement principles are as follows:

[0004] 1) Downward: 1700-1, 2300-1, 1700-2, 2300-2;

[0005] 2) Uplink: 2000-1, 2600-1, 2000-2, 2600-2.

[0006] The problem of the prior art is that when there are two stations in a field connection relationship and there is a field connection splicing route between the two train yards, the starting station of the field connection route splices a complete field connection route according to the interlocking route conditions on the own station side and the interlocking route conditions on the adjacent station side, and controls the track circuit coding of the throat section of the field connection route on the own station side according to the field connection route status; the terminal station of the field connection route only controls the track circuit coding of the route throat section according to the interlocking route status on the own station side. When the field connection terminal route corresponds to multiple field connection starting end splicing routes, and the coding principles of the sections within the field connection route are different (such as: track-coded stations, the field connection terminal route is straight, and the direction of the starting end route has two situations: lateral and straight. The section within the straight field connection route is coded according to the route departure section, and the section within the lateral field connection route sends a detection code), the terminal station of the field connection route cannot distinguish and control the coding of the section within the terminal route according to the starting end route status on the adjacent station side.

[0007] Therefore, it is necessary to provide a new field-linked terminal access intra-section coding control method, system, equipment and medium to solve the above-mentioned technical problems. Summary of the invention

[0008] The purpose of the present disclosure is to provide a method, system, device and medium for controlling segment coding within a field-linked terminal access route in order to solve the above-mentioned problems.

[0009] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0010] A method for controlling the section coding in the terminal route of a field connection is applicable to the scenario where two stations have a field connection relationship and there is a field connection splicing route between the two stations. The station that controls the terminal route coding is set as the station, and the station that controls the starting route coding is set as the adjacent station. The method is characterized by comprising the following steps:

[0011] The same terminal route corresponds to multiple field-linked routes, and the section coding principle of the terminal station route of the field-linked route is established;

[0012] Receive relevant route information from the interlocking center of this station and the train control center TCC of the neighboring station;

[0013] The relevant route information is updated based on a preset judgment condition to obtain updated relevant route information;

[0014] The section coding within the field-linked terminal route is controlled based on the section coding principle within the terminal station route of the field-linked route and the updated related route information.

[0015] As a further optimization scheme of the present disclosure, the section coding principle of the terminal station approach of the field connection approach includes:

[0016] The communication with the neighboring station is interrupted, and the throat section of the field connection access road on the station side is controlled to send a detection code;

[0017] When only handling the access road on the station side, control the throat section in the field access road on the station side to send the detection code;

[0018] This station has handled the field joint approach. When the approach condition at the beginning of the adjacent station is the lateral approach, the inner branch area of ​​the terminal approach at this station is controlled to issue codes according to the lateral approach conditions until the approach at this station is cancelled or completely unlocked.

[0019] This station has handled the field-connected approach. When the starting approach condition on the adjacent station side is a straight approach, the inner branch area of ​​the terminal approach on this station side is controlled to issue codes according to the straight approach condition until the approach on this station side is cancelled or completely unlocked.

[0020] As a further optimization scheme of the present disclosure, the section coding principle of the terminal station approach of the field connection approach also includes:

[0021] When there is a frequency change in the lateral approach to the track-coded station or the starting approach to the adjacent station, the section within the terminal approach sends a detection code.

[0022] As a further optimization solution of the present disclosure, the relevant route information of the train control center TCC receiving the interlocking of the local station and the adjacent station includes:

[0023] Receive terminal route information from this station interlocking;

[0024] Receive the starting route information from the train control center TCC of the neighboring station.

[0025] As a further optimization solution of the present disclosure, the relevant route information is updated based on a preset judgment condition, and the updated relevant route information includes:

[0026] Determine whether the terminal route on the station side exists; if not, delete the field-linked route that has been successfully combined with the current terminal route in the TCC route information table of the train control center of the station, and obtain the updated relevant route information; if yes, proceed to the next step;

[0027] Determine whether the terminal route start signal on the station side is open. If not, update the signal status of the field-linked route that has been successfully combined with the current terminal route in the TCC route information table of the station train control center to obtain the updated relevant route information; if yes, proceed to the next step;

[0028] Determine whether the communication between the station and the neighboring station is interrupted. If so, delete the field link route that has been combined with the terminal route on the station side to obtain the updated relevant route information; if not, proceed to the next step;

[0029] Determine whether the conditions for the starting route on the adjacent station side are not met or whether the starting route signal on the adjacent station side is closed. If so, maintain the TCC route information table of the train control center of this station and obtain the updated relevant route information.

[0030] As a further optimization scheme of the present disclosure, it is determined whether the conditions for the starting route on the adjacent station side are not met or whether the route signal on the adjacent station side is turned off. If not, it is continued to be determined whether all the conditions for the starting route on the adjacent station side are met. If not, the TCC route information table of this station is maintained to obtain the updated relevant route information; if so, the route that is successfully combined with the current terminal route is added to the TCC route information table of the train control center of this station, and the route that has been successfully combined with the terminal route on the station side is deleted from the TCC route information table of the train control center of this station to obtain the updated relevant route information.

[0031] As a further optimization scheme of the present disclosure, based on the section coding principle of the terminal station route of the field-linked route and the updated related route information control coding, the following are included:

[0032] Determine whether there is any field-connected combined approach corresponding to the terminal approach on the station side in the TCC approach information table of the station train control center. If so, based on the section coding principle of the terminal station approach of the field-connected approach, the terminal approach branch area is controlled by the TCC of the station train control center to send a detection code; if not, based on the section coding principle of the terminal station approach of the field-connected approach, the terminal approach is controlled by the TCC of the station train control center to control the coding according to the current combined approach design requirements.

[0033] A section coding control system within a terminal approach of a field connection is applicable to a scenario where two stations have a field connection relationship and a field connection splicing approach exists between the two stations. The two stations are described as an adjacent station and a local station respectively, including:

[0034] The coding principle construction module is used to correspond the same terminal route to multiple field-linked routes and to construct the coding principle of the terminal route section of the field-linked route;

[0035] Information receiving module, used to receive the relevant route information of the neighboring station TCC and the interlocking of this station;

[0037] A coding control module is used to control the coding of the sections within the terminal route of the field-linked route based on the coding principle of the sections within the terminal route of the field-linked route and the updated related route information.

[0041] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements a method for controlling segment coding within a field-linked terminal approach.

[0042] The beneficial effects of the present disclosure are:

[0043] The present invention aims at the shortcomings of the prior art. When the terminal station interlocking approach of the field-linked approach corresponds to multiple field-linked spliced ​​approaches, and the coding principles of the sections within the field-linked approaches are different, the field-linked approach terminal station issues codes according to the field-linked terminal approach conditions on the station side, the field-linked approach conditions at the starting end of the adjacent station side, and the status of the departing section. When the field-linked approach is a straight approach, the section within the control terminal approach is coded according to the coding principle for the straight approach; when the field-linked approach is a lateral approach, the section within the control terminal approach is coded according to the coding principle for the lateral approach. For cross-field approaches, the terminal station can issue codes according to the different control branch areas of the combined field-linked approaches, so that the field-linked approach coding control is applicable to more scenarios.

[0050] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0051] like Figure 1 As shown, a method for controlling the section coding within the terminal approach of a field connection is applicable to the scenario where two stations have a field connection relationship and there is a field connection splicing approach between the two stations. The station for controlling the terminal approach coding is set as the station (i.e., the field connection B station), and the station for controlling the starting approach coding is set as the adjacent station (i.e., the field connection A station), including the following steps:

[0052] The same terminal route corresponds to multiple field-linked routes, and the section coding principle of the terminal route of the field-linked route is established;

[0053] Receive relevant route information from the interlocking center of this station and the train control center TCC of the neighboring station;

[0054] The relevant route information is updated based on a preset judgment condition to obtain updated relevant route information;

[0055] The section coding within the field-linked terminal route is controlled based on the section coding principle within the terminal station route of the field-linked route and the updated related route information.

[0056] Specifically, Figure 2 As shown, the relevant route information of receiving station A and station B includes:

[0057] Receive the terminal route information of the field route from the interlocking of station B;

[0058] Receive the starting route information of the adjacent station of the field connection route from the train control center TCC of station A.

[0059] The relevant route information is updated based on the preset judgment condition, and the updated relevant route information includes:

[0060] Determine whether the terminal route on the B station side exists; if not, delete the route that has been successfully combined with the current terminal route in the TCC route information table of the train control center of the B station, and obtain the updated relevant route information; if yes, proceed to the next step;

[0061] Determine whether the terminal route start signal on the B station side is open. If not, update the route signal status that has been successfully combined with the current terminal route in the TCC route information table of the B station train control center to obtain the updated relevant route information; if yes, proceed to the next step;

[0062] Determine whether the communication between station B and station A is interrupted. If so, delete the route that has been combined with the route on the side of station B to obtain the updated relevant route information; if not, proceed to the next step;

[0063] Determine whether the access conditions on the station A side are not met or whether the access signal on the adjacent station (i.e., station A) side is closed. If so, maintain the TCC access information table of the station B train control center to obtain updated relevant access information; if not, continue to determine whether all access conditions on the station A side are met. If not, maintain the TCC access information table of the station B station to obtain updated relevant access information; if so, add the access that is successfully combined with the current terminal access to the TCC access information table of the station B train control center, and delete the access that has been successfully combined with the station B side access from the TCC access information table of the station B train control center to obtain updated relevant access information.

[0064] The section coding principle of the terminal route based on the field-linked route and the updated related route information control coding include:

[0065] Determine whether there is any field-linked combined approach corresponding to the terminal approach in the TCC approach information table of the station B train control center. If so, based on the section coding principle within the terminal approach of the field-linked approach, the station B train control center TCC controls the terminal approach branch area to send a detection code; if not, based on the section coding principle within the terminal station approach of the field-linked approach, the station B train control center TCC controls the terminal approach and controls the coding according to the current combined approach design requirements.

[0066] In this embodiment, for cross-field routes, the terminal route needs to determine the scenario of the route section coding based on the handling of the first route. The same terminal route is mapped to multiple field-linked routes, and the terminal station route section coding of the field-linked route follows the following principles:

[0067] 1) The communication with the neighboring station is interrupted, and the throat section of the side field connection route of the station (i.e. station B) is controlled to send a detection code;

[0068] 2) When only handling the access route on the station side, control the throat section in the field access route on the station side to send the detection code;

[0069] 3) When the station has handled the field connection approach and the condition of the starting approach at the adjacent station is the lateral approach, the branch area in the terminal approach at the station side is controlled to send codes according to the lateral approach conditions (when the lateral approach at the station is coded, or when there is a frequency conversion at the starting approach at the adjacent station side, the section in the terminal approach sends a detection code) until the approach at the station side is cancelled or completely unlocked;

[0070] 4) This station has processed the field-connected approach. When the starting approach condition on the adjacent station side is a straight approach, the inner branch area of ​​the terminal approach on this station side is controlled to issue codes according to the straight approach condition until the approach on this station side is cancelled or completely unlocked.

[0071] like Figure 3 and Figure 4 As shown in the scenario. The TCC splicing of the field connection route from SJ or SJF at field connection station A to 5G at field connection station B is realized. The ND208 virtual signal point is set between the 125# / 127# turnouts at field connection station A and field connection station B. SJ (SJF) -> ND208 is controlled by the TCC at field connection station A, and ND208 -> S5 route is controlled by the TCC at field connection station B. Figure 3 As shown in the figure, there is uplink and downlink carrier frequency conversion in the SJ port to 5G field connection combined approach, and the branch area sends a 27.9Hz detection code. Figure 4 As shown, there is no uplink and downlink carrier frequency conversion from the SJF port to the 5G field-linked combined route, and the branch area sends codes according to the full route. As the terminal station of the field-linked station B, the ND208->S5 route branch area needs to control the coding in combination with the route situation of station A. The specific implementation plan is as follows:

[0072] 1. Receive relevant route information:

[0073] The TCC of the field-linked station B receives the route information sent by the interlocking and the starting route information required for the field-linked combined route sent by the TCC of the adjacent station A;

[0074] 2. Update relevant route information:

[0075] If the received interlocking information exists in the terminal route ND208->S5 of station B:

[0076] 1) The ND208->S5 route signal is open, the TCC communication between station B and station A is interrupted, and the field-linked route that has been successfully combined with the ND208->S5 route in the TCC route information table of station B is cleared;

[0077] 2) ND208->S5 route signal is open, station B and station A TCC communication is normal, but station A route does not exist or the signal is not open, and the field link route information in station B TCC route information table is not updated;

[0078] 3) ND208->S5 route signal is open, station B and station A TCC communication is normal, station A route exists and the signal is open, add the current successfully combined field-linked route information to the station B TCC route information table, and delete the previously combined field-linked route information in the route information table;

[0079] 4) ND208->S5 route signal is turned off, and the current combined successful field route information is updated in the TCC route information table of station B;

[0080] If the received interlocking information does not contain the terminal route ND208->S5 information of station B, the field interlocking route information that is successfully combined with ND208->S5 will be deleted from the TCC route information table of station B.

[0081] 3. Control coding according to relevant route information:

[0082] For the TCC route information table of station B, if there is no field-linked combined route related to the ND208->S5 route, the control branch area 121-127DG will send a detection code;

[0083] If there is a field-linked combination route related to the ND208->S5 route, the coding shall be controlled according to the design requirements of the corresponding field-linked combination route.
