Description

Technical Field

[0001] This invention relates to the field of railway signaling technology, and in particular to a method for continuous train departure in sections based on a semi-automatic block circuit and the semi-automatic block circuit itself. Background Technology

[0002] On a single-track railway, only one train is allowed to run between two stations. To ensure that no two or more trains run between two stations, a combination of computer interlocking system and semi-automatic block circuit is commonly used to ensure the safety of train operation in the section.

[0003] With the development of society and the economy, higher demands are being placed on railway transportation capacity, making the promotion of moving block signaling technology a trend in the railway signaling industry. For single-track railways, the primary challenge in moving block signaling technology is how to ensure continuous train departures within the same section of track. Achieving this requires upgrading the existing station computer interlocking systems to meet the need for continuous train departures within the same section. However, upgrading the computer interlocking system involves comprehensive simulation testing and field trials by relevant station departments. Furthermore, the computer interlocking system communicates with other signaling systems (such as centralized dispatching systems and centralized signal monitoring systems), requiring varying degrees of functional upgrades and modifications to the related signaling equipment. Each upgrade and modification necessitates simulation testing and field trials by the station departments. Each upgrade increases project investment costs, and the associated testing extends the project construction period. Field trials of the computer interlocking system typically require halting existing station operations, reducing the original railway transportation capacity. The duration of the field trials depends on the size of the station.

[0004] Therefore, the above analysis shows that for single-track railways, the promotion of existing moving block signaling technology faces objective problems such as high project investment costs, long construction time, and impact on railway transportation efficiency during field testing. Summary of the Invention

[0005] In view of this, the present invention provides a method for continuous train departure in a section based on a semi-automatic block circuit. The main objective is to modify the existing semi-automatic block circuit at the station to meet the requirement of "how to continuously depart trains into the same section" in the moving block system, while without modifying the computer interlocking system, thereby solving the problems encountered in the promotion of the moving block system. Another objective of the present invention is to provide a semi-automatic block circuit suitable for the above method.

[0006] To achieve the above objectives, one technical solution of the present invention is to provide a method for continuous train departure in a section based on a semi-automatic block circuit. In the semi-automatic block circuit of the station, a continuous departure relay (LXFCJ) corresponding to the section entrance of the station is set up to control the continuous departure status of the section entrance of the station.

[0007] According to the start command for continuous departure, the continuous departure relay (LXFCJ) is activated to disable the operation of the semi-automatic block circuit that occurs as the train departs from the station.

[0008] Optionally, when the continuous departure relay (LXFCJ) operates according to the continuous departure start command, it disables the operation of the track relay (GDJ) in the semi-automatic block circuit of this station.

[0009] Optionally, when the continuous departure relay (LXFCJ) receives the start command for continuous departure, it disables the operation of the track relay (GDJ) caused by the operation of the first track section relay (DGJ) within the station.

[0010] The first track section relay (DGJ) inside the station corresponds to the first track section inside the station's entrance signal.

[0011] Optionally, according to the stop command for continuous departure, the continuous departure relay (LXFCJ) is driven to operate again to stop shielding the operation of the semi-automatic block circuit.

[0012] Optionally, the method for continuous departure within a section includes the following process:

[0013] Step 1: After completing the departure procedures at the station's section entrance and the receiving procedures at the adjacent station's section entrance, for this station, the block relay (BSJ), selection relay (XZJ), preparation to open relay (ZKJ), track relay (GDJ), and opening relay (KTJ) will be activated, and the departure indicator light at this station will turn green.

[0014] Step 2: For the adjacent station, the block relay (BSJ) drops, the train acceptance relay (TJJ) picks up, and the train acceptance indicator light at the adjacent station turns green;

[0015] Step 3: When continuous train departures are required to the station's section entrance, the station duty officer issues a continuous departure start command, which activates the continuous departure relay (LXFCJ). When the first train under continuous departure departs from the station and enters the first track section inside the station's entry signal, the activated continuous departure relay (LXFCJ) blocks the action of the first track section relay (DGJ) inside the station from falling, and in turn blocks the action of the station's track relay (GDJ) from falling, allowing several trains to continuously depart to the station's section entrance according to the set intervals.

[0016] Optionally, the method for continuous departure within a given section further includes the following process:

[0017] Step 4: When continuous train departures to the station's section entrance are no longer needed, the station duty officer issues a stop command for continuous departures, causing the continuous departure relay (LXFCJ) to drop. When the last train under continuous departures departs from this station and enters the first track section inside the station's entry signal, the corresponding first track section relay (DGJ) inside the station drops. For this station, the track relay (GDJ) drops, the block relay (BSJ) drops, the ready-to-open relay (ZKJ) drops, the positive relay (ZDJ) is activated, the opening relay (KTJ) drops, and the station's departure indicator light turns red. At this point, this station can no longer send trains to the station's section entrance.

[0018] Furthermore, when the positive relay (ZDJ) of this station is activated, for the adjacent station, the main line relay (ZXJ) is activated, the departure notification relay (TCJ) is activated, the track relay (GDJ) is activated, the train acceptance relay (TJJ) is deactivated, and the train acceptance indicator light of the adjacent station is displayed in red.

[0019] Step 5: After the last train in continuous departures enters the first track section inside the entrance signal of the adjacent station, the first track section relay (DGJ) inside the adjacent station corresponding to this section drops, the track relay (GDJ) of the adjacent station drops, and the receipt arrival relay (HDJ) of the adjacent station is activated.

[0020] Step 6: After the last train in continuous departures clears the first track section inside the entrance signal of the adjacent station, the duty officer of the adjacent station presses the reset button set in the operation display of the computer interlocking system to restore the semi-automatic block circuit of this station and the adjacent station to the initial state; if the train is to depart again, the two stations need to re-process the block procedures.

[0021] Optionally, this station can be any station on the railway line, and the railway between this station and the adjacent station receiving the train is a single track.

[0022] Optionally, a continuous departure button corresponding to the section entrance of this station is provided on the control panel in the station operations room;

[0023] When the station duty officer presses the continuous departure button, he gives the start command for continuous departure, which drives the continuous departure relay (LXFCJ) to be activated, so that the semi-automatic block circuit is shielded from the semi-automatic block circuit operation when the first train under continuous departure departs from this station.

[0024] When the last train in continuous departure mode enters the departure route, the station duty officer presses the continuous departure button again to give a stop command for continuous departure, which drives the continuous departure relay (LXFCJ) to drop, restoring the semi-automatic block circuit operation for the last train departing from the station.

[0025] Optionally, the continuous departure button is normally displayed in red;

[0026] After pressing the continuous departure button and giving the start command for continuous departure, the continuous departure button will display green;

[0027] Press the continuous departure button again to give a stop command for continuous departure, and the continuous departure button will turn red.

[0028] Optionally, the departure routes of this station include any of the following:

[0029] The track section between the exit signal and the entrance signal of the main line at this station;

[0030] The track section between the exit signal and the entrance signal of the siding track at this station.

[0031] Another technical solution of the present invention is to provide a semi-automatic block circuit for any of the above-mentioned continuous train departure methods in the section;

[0032] In the semi-automatic block circuit of the station, a continuous departure relay (LXFCJ) corresponding to the section opening of the station is set up to control the continuous departure status of the section opening of the station.

[0033] The continuous departure relay (LXFCJ) is equipped with an instruction issuing element, which is used to provide instructions to drive the continuous departure relay (LXFCJ) to operate; the instructions include a continuous departure start instruction, which is used to drive the continuous departure relay (LXFCJ) to operate, thereby disabling the operation of the semi-automatic block circuit that occurs as the train departs from the station.

[0034] Optionally, the instruction may further include a stop instruction for continuous departure, used to drive the continuous departure relay (LXFCJ) to activate again and stop shielding the operation of the semi-automatic block circuit.

[0035] Optionally, in the semi-automatic block circuit of this station, the excitation circuit of the track relay (GDJ) is configured with one set of acquisition and drive contacts from each of the following relays: continuous departure relay (LXFCJ), preparation to start relay (ZKJ), notification departure relay (TCJ), and the first track section relay (DGJ) within the station; each set of acquisition and drive contacts includes a front contact, a middle contact, and a rear contact.

[0036] The first track section relay (DGJ) inside the station corresponds to the first track section inside the station's entrance signal.

[0037] The front and rear coils of the track relay (GDJ) are connected in series. Normally, it is in a demagnetized and falling state. The rear coil of the track relay (GDJ) is connected to the negative power supply (KF).

[0038] The front coil of the track relay (GDJ) is connected to the connection point of the front contact of the ready-to-activate relay (ZKJ) and the front contact of the notification-to-depart relay (TCJ).

[0039] The connection point of the intermediate contact of the preparation to activate relay (ZKJ) and the connection point of the intermediate contact of the notification departure relay (TCJ) are connected to the connection point of the front contact of the first track section relay (DGJ) within the station and the connection point of the front contact of the continuous departure relay (LXFCJ).

[0040] The center contact of the first track section relay (DGJ) within the station and the connection point of the continuous departure relay (LXFCJ) are connected to the positive power supply (KZ).

[0041] Initially, the preparation to activate relay (ZKJ), the notification departure relay (TCJ), and the continuous departure relay (LXFCJ) are all in the open state, while the first track section relay (DGJ) within the station is in the closed state.

[0042] Optionally, the instruction issuing element includes a continuous departure button corresponding to the section entrance of this station, which is set on the control panel in the station operation room of this station;

[0043] When the station duty officer presses the continuous departure button twice, the instruction given switches between the start instruction and the stop instruction of the continuous departure, which is used to drive the continuous departure relay (LXFCJ) to switch between the lifting and lowering actions.

[0044] Optionally, the continuous departure button is normally displayed in red;

[0045] After pressing the continuous departure button and giving the start command for continuous departure, the continuous departure button will display green;

[0046] Press the continuous departure button again to give a stop command for continuous departure, and the continuous departure button will turn red.

[0047] Optionally, this station can be any station on the railway line, and the connection between this station and the receiving neighboring station is a single-track railway. In the semi-automatic block circuit of the neighboring station, there is a continuous departure relay (LXFCJ) and its command issuing element corresponding to the section gate of the neighboring station, which is used to control the continuous departure status of the section gate of the neighboring station.

[0048] Compared with the prior art, the present invention has the following advantages:

[0049] 1. No modification to the computer interlocking system is required;

[0050] 2. When not using the moving block system, it is completely consistent with the existing industry semi-automatic block system standards;

[0051] 3. When using the moving block signaling system, continuous train departures to the same section of track can be achieved;

[0052] 4. The project construction and maintenance work is simple. Attached Figure Description

[0057] Detailed Implementation

[0058] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0059] In existing technology, station computer interlocking systems are combined with semi-automatic block circuits to achieve semi-automatic block signaling functions. Figure 1For example, this is a schematic diagram of the signaling equipment between two stations on a railway line in the existing technology, where A and B are adjacent stations, and the railway between the two stations is a single track. Figure 1 The diagram shows the entrance signal S, exit signals X3, XII, X1, and shunting signal D2 at station A; the entrance signal X and exit signals S3, SII, and S1 at station B, along with their respective light positions; the mainline track IIG, siding tracks 1G and 3G at stations A and B; the first track section inside the entrance signal S (in this example, the switchless section IIBG); the approach track SJG outside the entrance signal S; and the approach track XJG outside the entrance signal X (the dashed section between SJG and XJG represents the section without track circuits); "1", "2", "3", and "4" are the numbers of the four single-action turnouts, and 1DG, 2DG, 3DG, and 4DG are the track sections corresponding to these turnouts. In this example, section 1DG is the first track section inside the entrance signal X.

[0060] Figures 2-9 This refers to the existing semi-automatic block signaling circuit installed at Station A (described in detail below), which includes 13 types of relays: Positive relay ZDJ, used to send positive block signals; Negative relay FDJ, used to send negative block signals; Positive line relay ZXJ, used to receive positive block signals; Negative line relay FXJ, used to receive negative block signals; Block relay BSJ, used to monitor and indicate the status of the block machine. It is energized when the block machine is in the positioning state, indicating that the section is clear. When the station is in operation, it is de-energized when a train occupies the section, indicating that the section is blocked; Arrival receipt relay HDJ, together with TJJ, forms an automatic receipt circuit to send receipt signals and record train arrivals; Approval to receive relay TJJ, used to record the departure request signal from the other station and switch the block machine to the receiving state, and together with HDJ, forms an automatic receipt circuit; Notification of departure relay TCJ, used to record the train departure notification signal from the other station. The KTJ relay is used to record the acceptance signal from the receiving station and control the opening of the departure signal. The XZJ relay is used to select and distinguish between automatic acknowledgment signals and reset signals; it monitors whether the departure signal is open during departure processing. The ZKJ relay is used to record the automatic acknowledgment signal from the other station. The FUJ relay is used to receive the reset signal and reset the block mechanism. The GDJ track relay is a repeater relay for the field track relays, monitoring train departures and arrivals.

[0061] Figures 2-9The diagram also shows the relays IIBG-GDJ corresponding to the IIBG track section. The receiving red light relay JDHJ, receiving yellow light relay JDUJ, receiving green light relay JDLJ, departure red light relay FDHJ, departure yellow light relay FDUJ, and departure green light relay FDLJ are used to reflect the status of the corresponding indicator lights. The blocking button relay BSAJ, reset button relay FUAJ, and emergency button relay SGAJ reflect the status of the corresponding buttons BSA, FUA, and SGA, respectively. Additionally, the departure locking relay FSBJ, receiving locking relay JSBJ, and train departure terminal relay LFZJ, driven by the interlocking system, are shown.

[0062] Figures 2-9 In the diagram, "↑" indicates the relay is activated, and "↓" indicates the relay is deactivated. The numbers "1", "2", "3", "4", "5", "6", "7", and "8" on each relay represent the relay's data acquisition and drive contacts. A single relay can include multiple sets of data acquisition and drive contacts, distinguished by different numbers (each set has a front contact, a middle contact, and a rear contact). "S" represents the name of the section gate at station A; "X" represents the name of the section gate at station B. This invention uses the semi-automatic block circuit at station A as an example for illustration (each relay will be represented by its symbol). Figures 2-9 After replacing “S-” with “X-”, it becomes the semi-automatic block circuit set up at station B.

[0063] To achieve continuous train departures within a section based on a semi-automatic block circuit, the present invention includes the design of a continuous departure button and modifications to the semi-automatic block circuit.

[0064] 1. Continuous departure button design

[0065] The station operations room control panel, where station duty officers work daily, is equipped with continuous departure buttons for each section of the station. Figure 1 Taking the railway line shown as an example, station A needs to add a continuous departure button at section S. Section S refers to the section between station A's entrance signal S and station B's entrance signal X.

[0066] 1) The continuous departure button at the S section entrance is normally displayed in red;

[0067] 2) When continuous departures are required at the S section gate, press the S section gate continuous departure button. The S section gate continuous departure button will turn green, and at the same time, the corresponding S section gate continuous departure relay (S-LXFCJ) will be activated.

[0068] 3) When the S-section continuous departure button is pressed again, the S-section continuous departure button will turn red, and the corresponding S-section continuous departure relay (S-LXFCJ) will drop.

[0069] Figures 2-9 The existing semi-automatic block signaling circuit shown is briefly described below:

[0070] 1) Once the departure procedures at the S section entrance of Station A and the receiving procedures at the X section entrance of Station B are completed, the departure indicator lights at Station A (S-BSJ↑, S-XZJ↑, S-ZKJ↑, S-GDJ↑, S-KTJ↑) will turn green.

[0071] 2) At Station B, the X-BSJ↓, X-TJJ↑, and the arrival indicator lights are green;

[0072] 3) After the first train departs from Station A, it enters the IIBG section of Station A. The train departure indicator lights at Station A turn red. From this point on, Station A can no longer send trains to the S section entrance.

[0073] 4) Following item “3)”, after S-ZDJ↑ at station A, X-ZXJ↑, X-TCJ↑, X-GDJ↑, X-TJJ↓ at station B, and the arrival indicator light at station B will turn red;

[0074] 5) After the train enters the 1DG section of station B, 1DG-DGJ↓, and X-GDJ↓ and X-HDJ↑ at station B;

[0075] 6) After the train clears the 1DG section of Station B, the station B duty officer presses the reset button on the control panel of the computer interlocking system, and the semi-automatic block circuits of both Stations A and B are reset to their initial state. Figures 2-9 The middle state is the initial state of the semi-automatic block circuit. If a train is to depart again, both stations A and B need to re-apply for block procedures.

[0076] 2. Modification of semi-automatic block circuit

[0077] This invention addresses the original Figure 8 The circuit diagram of the intermediate track relay was modified to set up a continuous departure relay (S-LXFCJ) at the S section entrance of Station A. A dashed box was added to the section, as shown below. Figure 10 As shown.

[0078] Original Figure 8In this configuration, the front and rear coils of S-GDJ are connected in series. Normally, it is in a demagnetized, fallen state. The fourth coil is connected to the negative power supply KF, and the first coil is connected to the front contacts of S-ZKJ6 and S-TCJ4 (S-ZKJ6 represents the sixth group of acquisition drive contacts of S-ZKJ, and S-TCJ4 represents the fourth group of acquisition drive contacts of S-TCJ; the representation of relays and their respective acquisition drive contacts is similar below and will not be repeated). The middle contacts of S-ZKJ6 and S-TCJ4 are connected to the front contacts of IIBG-DGJ, and the middle contact of IIBG-DGJ is connected to the positive power supply KZ. Initially, the front contacts of S-ZKJ6 and S-TCJ4 are open, while the front contact of IIBG-DGJ is closed.

[0079] like Figure 10 As shown, the front contact of the S-LXFCJ of this invention is connected in parallel with the front contact of the IIBG-DGJ, and is also connected to the middle contact of the S-ZKJ6 and the middle contact of the S-TCJ4; the middle contact of the S-LXFCJ is connected in parallel with the middle contact of the IIBG-DGJ, and is connected to the positive power supply KZ. Initially, the front contact of the S-LXFCJ is open.

[0080] In the continuous train departure method of the present invention, firstly, in accordance with the existing semi-automatic block signaling technology requirements, the departure procedures at the S section entrance of station A and the receiving procedures at the X section entrance of station B are completed, and the S-ZKJ and S-GDJ of station A are increased.

[0081] If Station A needs to continuously dispatch trains to Section S, the station operator presses the "Continuous Departure from Section S" button, which activates the S-LXFCJ relay, thus blocking the S-GDJ↓ caused by IIBG-DGJ↓. This prevents the semi-automatic block circuit from operating as the first train departs from Station A, meaning that the above "3) to 6) processes will no longer be executed from the first train onwards.

[0082] When Station A does not need to continuously dispatch trains to Section S, when the last train enters the departure route, the station operator presses the "Continuous Departure from Section S" button again. The S-LXFCJ relay drops, restoring the existing semi-automatic block circuit, that is, resuming the execution of the above "3) to 6) process for the last train.

[0083] Specifically, the departure routes of Station A are: 1) X1-S departure route, including sections 4DG, 2DG, and IIBG; 2) XII-S departure route, including sections 4DG, 2DG, and IIBG; and 3) X3-S departure route, including sections 2DG and IIBG.

[0084] The continuous departure function of section X and section S is the same, and will not be described again here. In this invention, during continuous departures, the spatial interval between adjacent trains is controlled by other signaling systems.
