Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and in particular, to an interface circuit and a communication method between a full-electronic computer interlocking and a relay centralized interlocking. Background Art

[0002] With the rapid development of urban rail transit, the total length of operating lines has been increasing rapidly year by year, and the operating cycle of the lines has been continuously increasing, resulting in problems such as major overhauls, renovations, and equipment updates for most urban rail transit lines.

[0003] With the rapid popularization of full-electronic interlocking computer technology, its advantages of simple structure, less equipment floor space, flexible deployment, and convenient construction and maintenance have made full-electronic interlocking also show obvious advantages in urban rail transit major overhaul and renovation projects. However, due to the segmented situation in the current urban rail transit line renovation process, there is a part using full-electronic computer interlocking and a part using traditional relay centralized interlocking, and there is a situation of using relay interfaces between the full-electronic computer interlocking and the relay centralized interlocking. During the project renovation process, the vehicle depot needs to be renovated into full-electronic computer interlocking equipment, and the main line stations continue to use relay centralized interlocking. Most of the interfaces between the vehicle depot and the main line stations in the relay centralized interlocking are relay interfaces, that is, the information of the two interlocking areas of the vehicle depot and the main line station is mutually transmitted through the circuit built by relays between the two interlockings to realize the normal entry and exit of trains from the depot.

[0004] However, in urban rail transit major overhaul and renovation projects, some interlocking areas need to be newly built or renovated into full-electronic computer interlocking systems. Some projects still need to retain the relay interfaces of the relay centralized interlocking at one end of the main line or the vehicle depot and require the mutual transmission of information at the interfaces to remain unchanged. For example, the existing vehicle depot needs to be renovated into full-electronic computer interlocking, and the existing main line stations remain unchanged as relay centralized interlocking.

[0005] Therefore, how to realize the normal communication between the two interlocking areas of the full-electronic computer interlocking and the relay centralized interlocking is an urgent problem to be solved at present. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention 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. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Figure 1 It is a schematic structural diagram of the interface circuit between the all - electronic computer interlocking and the relay centralized interlocking provided by the present invention, asFigure 1 As shown in the figure, it includes:

[0031] A first circuit, including: a first signal machine checking relay in the all-electronic computer interlocking area and a first signal machine checking repeat relay in the relay interlocking area. The first circuit is used to determine whether to allow the handling of a first train route with a first signal machine as the terminal signal machine arranged in the all-electronic computer interlocking area according to the states of the first signal machine checking relay and the first signal machine checking repeat relay. The first signal machine checking relay and the first signal machine checking repeat relay are electrically connected;

[0032] A second circuit, including: a first target track section track relay in the all-electronic computer interlocking area and a second signal machine approach notice repeat relay in the relay interlocking area. The second circuit is used to determine the occupancy state of the first target track section according to the states of the first target track section track relay and the second signal machine approach notice repeat relay. The first target track section is determined according to the track section adjacent to the second signal machine. The first target track section track relay and the second signal machine approach notice repeat relay are electrically connected;

[0033] A third circuit, including: a first signal machine train signal relay in the all-electronic computer interlocking area, a first signal machine guiding signal relay in the all-electronic computer interlocking area, a first signal machine train signal repeat relay in the relay interlocking area, and a first signal machine guiding signal repeat relay in the relay interlocking area. The third circuit is used to determine whether to allow the first signal machine to open the first train route according to the states of the first signal machine train signal relay, the first signal machine train signal repeat relay, the first signal machine guiding signal relay, and the first signal machine guiding signal repeat relay. The first signal machine train signal relay and the first signal machine train signal repeat relay are electrically connected, and the first signal machine guiding signal relay and the first signal machine guiding signal repeat relay are electrically connected.

[0034] Optionally, the present invention can be applied when the relay interlocking part of urban rail transit is transformed into all-electronic computer interlocking equipment or when the existing line uses relay interlocking and the newly built extension line uses all-electronic computer interlocking. There is both an existing relay interlocking area and a transformed or newly built all-electronic computer interlocking area to realize the normal operation of trains on the whole line.

[0035] During the overhaul and transformation of urban rail transit into all-electronic computer interlocking, since some projects still need to retain the relay interface of the interlocking area at one end of the main line station or the vehicle depot, the vehicle depot and the existing interlocking use a relay interface, and the mutual transmission of information at the interface remains unchanged.

[0036] For example, during the renovation of the above-mentioned depot and main line station, if only the depot is renovated into a fully electronic computer interlocking area and the main line station remains unchanged as a relay interlocking area, an interface circuit is required to enable normal communication between the fully electronic computer interlocking area (i.e., the depot) and the relay interlocking area (i.e., the main line station).

[0037] The interface circuit may specifically include a first circuit, a second circuit, and a third circuit. The first circuit may specifically include a first signal aspect checking relay and a first signal aspect checking repeat relay. The first signal is the XJC signal. The first signal aspect checking relay may specifically be XJC-ZCJ (including XJC-AZCJ and XJC-BZCJ), and the first signal aspect checking repeat relay may specifically be XJC-ZCJF. Among them, the first signal aspect checking relay XJC-ZCJ is deployed in the fully electronic computer interlocking area, the first signal aspect checking repeat relay XJC-ZCJF is deployed in the relay interlocking area, and the first signal aspect checking relay XJC-ZCJ is electrically connected to the first signal aspect checking repeat relay XJC-ZCJF.

[0038] The state of the first signal aspect checking relay XJC-ZCJ may specifically include two states: dropping and picking up. The state of the first signal aspect checking repeat relay XJC-ZCJF may specifically include two states: dropping and picking up. The first circuit may specifically be used to determine whether to allow the handling of the first train route arranged in the fully electronic computer interlocking area with the first signal XJC as the terminal signal based on the state (dropping or picking up) of the first signal aspect checking relay XJC-ZCJ and the state (dropping or picking up) of the first signal aspect checking repeat relay XJC-ZCJF. For example, when the state of the first signal aspect checking relay XJC-ZCJ is dropping and the state of the first signal aspect checking repeat relay XJC-ZCJF is also dropping, it is determined that the first train route is allowed to be handled.

[0039] The second circuit may specifically include a first target track section track relay and a second signal approach pre-warning repeat relay. The second signal is the F4 signal. The first target track section may specifically be the track section adjacent to the second signal F4 signal, more specifically the track section closest to the F4 signal. For example, refer to Figure 2 1 / 7DG in Figure 2 which is a schematic diagram of the layout of the interface position equipment between the fully electronic computer interlocking area and the relay interlocking area provided by the present invention.

[0040] The first target track section track relay can specifically be 1 / 7DG-GJ (including 1 / 7DG-AGJ and 1 / 7DG-BGJ), and the second signal approaching pre-warning repeat relay can specifically be F4-JYJF. Among them, the first target track section track relay 1 / 7DG-GJ is deployed within the all-electronic computer interlocking area, and the second signal approaching pre-warning repeat relay F4-JYJF is deployed within the relay interlocking area, and the first target track section track relay 1 / 7DG-GJ is electrically connected to the second signal approaching pre-warning repeat relay F4-JYJF.

[0041] The states of the first target track section track relay 1 / 7DG-GJ can specifically include two states: dropping and picking up, and the states of the second signal approaching pre-warning repeat relay F4-JYJF can specifically include two states: dropping and picking up. The second circuit can specifically be used to determine the occupancy state of the first target track section 1 / 7DG according to the states (dropping or picking up) of the first target track section track relay 1 / 7DG-GJ and the second signal approaching pre-warning repeat relay F4-JYJF. For example, when 1 / 7DG-BGJ drops and F4-JYJF also drops, it is determined that 1 / 7DG is occupied by a train.

[0042] The third circuit can specifically include the first signal train signal relay and the first signal guiding signal relay within the all-electronic computer interlocking area, as well as the first signal train signal repeat relay and the first signal guiding signal repeat relay within the relay interlocking area. The first signal train signal relay can specifically be XJC-LXJ (including XJC-ALXJ and XJC-BLXJ), and the first signal train signal repeat relay can specifically be XJC-LXJF, and the first signal train signal relay XJC-LXJ is electrically connected to the first signal train signal repeat relay XJC-LXJF. The first signal guiding signal relay can specifically be XJC-YXJ (including XJC-AYXJ and XJC-BYXJ), and the first signal guiding signal repeat relay can specifically be XJC-YXJF, and the first signal guiding signal relay XJC-YXJ is electrically connected to the first signal guiding signal repeat relay XJC-YXJF.

[0043] The states of the train signal relay XJC-LXJ of the first signal machine, the train signal repeat relay XJC-LXJF of the first signal machine, the guiding signal relay XJC-YXJ of the first signal machine, and the guiding signal repeat relay XJC-YXJF of the first signal machine can each specifically include two states: falling and picking up. The third circuit can specifically be used to determine whether to allow the first signal machine XJC to open the first train route based on the states of the train signal relay XJC-LXJ of the first signal machine, the train signal repeat relay XJC-LXJF of the first signal machine, the guiding signal relay XJC-YXJ of the first signal machine, and the guiding signal repeat relay XJC-YXJF of the first signal machine. For example, when XJC-LXJ is picked up, XJC-LXJF is picked up, XJC-YXJ is picked up, and XJC-YXJF is also picked up, the first signal machine XJC is allowed to open the first train route.

[0044] The interface circuit between the all-electronic computer interlocking and the relay interlocking provided by the present invention can achieve normal communication between the all-electronic computer interlocking area and the relay interlocking area when there are both all-electronic computer interlocking areas and relay interlocking areas on the train operation line, ensuring the safe operation of the train.

[0045] Further, in one embodiment, the interface circuit may specifically further include:

[0046] The fourth circuit includes: the second signal machine check repeat relay in the all-electronic computer interlocking area and the second signal machine check relay in the relay interlocking area. The fourth circuit is used to determine whether to allow the locking of the second train route arranged in the relay interlocking area with the second signal machine as the terminal signal machine based on the states of the second signal machine check repeat relay and the second signal machine check relay. The second signal machine check repeat relay and the second signal machine check relay are electrically connected;

[0047] The fifth circuit includes: the second signal machine train signal repeat relay in the all-electronic computer interlocking area and the second signal machine train signal relay in the relay interlocking area. The fifth circuit is used to determine whether to allow the handling of the third train route arranged in the relay interlocking area with the second signal machine as the starting signal machine based on the states of the second signal machine train signal repeat relay and the second signal machine train signal relay. The second signal machine train signal repeat relay and the second signal machine train signal relay are electrically connected;

[0048] The sixth circuit includes: a first signal approach pre-warning repeat relay within the all-electronic computer interlocking area and a first signal approach pre-warning relay within the relay interlocking area. The sixth circuit is configured to determine the occupancy status of a second target track section based on the statuses of the first signal approach pre-warning repeat relay and the first signal approach pre-warning relay. The first signal approach pre-warning repeat relay and the first signal approach pre-warning relay are electrically connected. The second target track section is determined based on the track section adjacent to the first signal.

[0049] Optionally, the interface circuit may further specifically include a fourth circuit, a fifth circuit, and a sixth circuit. The fourth circuit may specifically include a second signal check repeat relay and a second signal check relay. The second signal check repeat relay may specifically be F4-ZCJF (including F4-AZCJF and F4-BZCJF), and the second signal check relay may specifically be F4-ZCJ. Among them, the second signal check repeat relay F4-ZCJF is deployed within the all-electronic computer interlocking area, the second signal check relay F4-ZCJ is deployed within the relay interlocking area, and the second signal check relay F4-ZCJ is electrically connected to the second signal check repeat relay F4-ZCJF.

[0050] The statuses of the second signal check relay F4-ZCJ and the second signal check repeat relay F4-ZCJF may both specifically include two states: dropping and picking up. The fourth circuit may specifically be used to determine, based on the status of the second signal check repeat relay F4-ZCJF and the status of the second signal check relay F4-ZCJ, whether to allow the locking of a second train route arranged within the relay interlocking area with the second signal as the terminal signal. For example, when the status of the second signal check relay F4-ZCJ is dropping and the status of the second signal check repeat relay F4-ZCJF is also dropping, it is determined that the locking of the second train route is allowed to be handled.

[0051] The fifth circuit may specifically include a second signal train signal repeat relay and a second signal train signal relay. The second signal train signal repeat relay may specifically be F4-LXJF (including F4-ALXJF and F4-BLXJF), and the second signal train signal relay may specifically be F4-LXJ. Among them, the second signal train signal repeat relay F4-LXJF is deployed within the all-electronic computer interlocking area, the second signal train signal relay F4-LXJ is deployed within the relay interlocking area, and the second signal train signal relay F4-LXJ is electrically connected to the second signal train signal repeat relay F4-LXJF.

[0052] The states of the train signal relay F4-LXJ of the second signal machine and the train signal repeat relay F4-LXJF of the second signal machine can both specifically include two states: dropping and picking up. The fifth circuit can specifically be used to determine whether to allow arranging the third train route starting with the second signal machine F4 as the starting signal machine in the relay interlocking area based on the states of the train signal repeat relay F4-LXJF of the second signal machine and the train signal relay F4-LXJ of the second signal machine. For example, when F4-LXJ is picked up and F4-LXJF is also picked up, it is determined that the third train route can be arranged.

[0053] The sixth circuit can specifically include a first signal approach pre-warning repeat relay deployed in the all-electronic computer interlocking area and a first signal approach pre-warning relay deployed in the relay interlocking area. The first signal approach pre-warning repeat relay can specifically be XJC-JYJF (including XJC-AJYJF and XJC-BJYJF), the first signal approach pre-warning relay can specifically be XJC-JYJ, and the first signal approach pre-warning repeat relay XJC-JYJF is electrically connected to the first signal approach pre-warning relay XJC-JYJ.

[0054] The states of the first signal approach pre-warning repeat relay XJC-JYJF and the first signal approach pre-warning relay XJC-JYJ can both specifically include two states: dropping and picking up. The sixth circuit can specifically be used to determine the occupancy state of the second target track section based on the states of the first signal approach pre-warning repeat relay XJC-JYJF and the first signal approach pre-warning relay XJC-JYJ. The second target track section can specifically be the track section adjacent to the first signal machine XJC, and more specifically, the track section closest to the XJC signal machine (for example, see 4DG in Figure 2 . For example, when XJC-JYJF drops and XJC-JYJ is also picked up, it is determined that 4DG is occupied by a train.

[0055] Furthermore, in one embodiment, the first signal check relay, the first target track section track relay, the first signal train signal relay, the first signal guiding signal relay, the second signal check repeat relay, the second signal train signal repeat relay, and the first signal approach pre-warning repeat relay are all European standard relays.

[0056] Optionally, the first signal machine checking relay XJC-ZCJ, the first target track section track relay 1 / 7DG-GJ, the first signal machine train signal relay XJC-LXJ, the first signal machine guiding signal relay XJC-YXJ, the second signal machine checking repeat relay XJC-ZCJF, the second signal machine train signal repeat relay F4-LXJF, and the first signal machine approach warning repeat relay XJC-JYJF all adopt European standard relays. The design uses two European standard relays to replace the original gravity-type relays, and collects the dual-channel contacts of the two European standard relays to ensure that the safety of the interface circuit is not reduced.

[0057] It should be noted that referring to Figures 3 - 4 , in the all-electronic computer interlocking area, there is no LXJ and YXJ. In addition to driving the ZCJ, the interlocking needs to drive conditions such as LXJ and YXJ separately and perform feedback collection.

[0058] The all-electronic computer interlocking area needs to make the status of the collected 1 / 7DG-GJ into relevant driving commands, re-drive 1 / 7DG-AGJ and 1 / 7DG-BGJ, and send the occupancy status (occupied or cleared) of the 1 / 7DG in the vehicle depot to the main line station.

[0059] In addition, the all-electronic computer interlocking software needs to add relevant functions for the relay interface.

[0060] When the vehicle depot handles the route, after checking that the interlocking conditions (F4-ZCJ is pulled in, the opposing signal is not established, the track sections in the route are idle, etc.) are met, the route is locked and the XJC-ZCJ is driven to drop. After the main line interlocking collects the information that the XJC check drops, it is not allowed to arrange a route from the main line to the vehicle depot. During the signal opening process, the above interlocking conditions are continuously checked. If they are not met, the signal is closed, and the signal needs to be manually reopened after the interlocking conditions are met. When the train completely clears the 1 / 7DG track section and enters the main line, the XJC-ZCJ in the vehicle depot resumes being pulled in.

[0061] When the main line station handles the first train route with the XJC signal machine as the terminal signal machine, it is necessary to check that the XJC-ZCJ is pulled in before the route can be locked, and the F4-ZCJ is driven to drop. During the signal opening process, the above interlocking conditions are continuously checked. If they are not met, the signal is closed, and the signal needs to be manually reopened after the interlocking conditions are met. The approach locking section of the first signal machine XJC is 4DG.

[0062] The interface circuit between the all-electronic computer interlocking and the relay interlocking provided by the present invention can realize the normal communication between the all-electronic computer interlocking area and the relay interlocking area when there are both all-electronic computer interlocking areas and relay interlocking areas on the train operation line. At the same time, in the all-electronic computer interlocking area, two European standard relays are used to replace the original gravity-type relays, so that the safety of the relay interface circuit will not be reduced.

[0063] The communication method provided by the present invention will be described below. The communication method described below is implemented based on the interface circuit between the all-electronic computer interlocking and the relay centralized interlocking described above.

[0064] Figure 5 It is a schematic flowchart of the communication method provided by the present invention. As Figure 5 shown, it includes:

[0065] Step 110: Determine whether to allow the first train route with the first signal as the terminal signal to be arranged in the all-electronic computer interlocking area according to the states of the first signal aspect checking relay and the first signal aspect checking repeat relay in the first circuit. The first signal aspect checking relay is deployed in the all-electronic computer interlocking area, the first signal aspect checking repeat relay is deployed in the relay centralized interlocking area, and the first signal aspect checking relay and the first signal aspect checking repeat relay are electrically connected;

[0066] Step 120: Determine the occupancy state of the first target track section according to the states of the first target track section track relay and the second signal approach warning repeat relay in the second circuit. The first target track section track relay is deployed in the all-electronic computer interlocking area, the second signal approach warning repeat relay is deployed in the relay centralized interlocking area, the first target track section is determined according to the track section adjacent to the second signal, and the first target track section track relay and the second signal approach warning repeat relay are electrically connected;

[0067] Step 130: Determine whether to allow the first signal to open the first train route according to the states of the first signal train signal relay, the first signal train signal repeat relay, the first signal guiding signal relay, and the first signal guiding signal repeat relay in the third circuit. The first signal train signal relay and the first signal guiding signal relay are deployed in the all-electronic computer interlocking area, the first signal train signal repeat relay and the first signal guiding signal repeat relay are deployed in the relay centralized interlocking area, the first signal train signal relay and the first signal train signal repeat relay are electrically connected, and the first signal guiding signal relay and the first signal guiding signal repeat relay are electrically connected.

[0068] Further, in one embodiment, the method further includes:

[0069] When the states of both the first signal aspect checking relay and the first signal aspect checking repeat relay are dropped, it is determined that the first train route is allowed to be handled;

[0070] When it is determined that it is allowed to handle the first train route, control the track relay of the first target track section and the approach warning repeat relay of the second signal to drop.

[0071] When it is determined that it is allowed to handle the first train route, control the train signal relay of the first signal, the train signal repeat relay of the first signal, the approach signal relay of the first signal, and the approach signal repeat relay of the first signal to pick up.

[0072] Optionally, see Figures 1 - 2 , based on the first to third circuits, the all-electronic computer interlocking area (depot) sends the following information to the relay interlocking area (main line station):

[0073] The XJC-A / BZCJ in the depot is normally picked up, and through the interface circuit, the XJC-ZCJF in the main line station is also normally picked up; when the first train route with the XJC signal as the terminal signal is arranged in the depot, the XJC-A / BZCJ in the depot drops, and the XJC-ZCJF in the main line station drops accordingly; after the last section 1 / 7DG of the route is unlocked, it resumes picking up. This relay (XJC-A / BZCJ) is reserved in the interface circuit between the depot and the main line station, and the all-electronic computer interlocking can drive this relay (XJC-A / BZCJ) alone to implement the action logic of this relay (XJC-A / BZCJ).

[0074] Since the F4-JYJ interlocking logic cannot be implemented in the interface circuit of the all-electronic computer interlocking, after the transformation, the occupied state of 1 / 7DG-A / BGJ in the all-electronic computer interlocking area is used to replace the train approach state. The 1 / 7DG-A / BGJ in the depot is normally picked up, and through the interface circuit, the F4-JYJF in the main line station is also normally picked up; when there is a train occupying the 1 / 7DG in the approach section of the F4 signal, the 1 / 7DG-A / BGJ drops, and the F4-JYJF in the main line station drops accordingly; after 1 / 7DG is unlocked, it resumes picking up.

[0075] The XJC-A / BLXJ in the depot is normally dropped, and through the interface circuit, the XJC-LXJF in the main line station is also normally dropped; when the first train route is opened at the XJC signal, the XJC-A / BLXJ picks up, and through the interface circuit, the XJC-LXJF in the main line station picks up accordingly; after the last section of the first train route is unlocked, it resumes dropping. Realize the information transfer from the depot to the main line station. After the transformation, the all-electronic computer interlocking area drives this relay (XJC-A / BLXJ) alone to implement the action logic of this relay (XJC-A / BLXJ), and this relay (XJC-A / BLXJ) is reserved in the interface circuit between the depot and the main line station.

[0076] The relay XJC-A / BYXJ in the depot is in the normally dropped state, and the relay XJC-YXJF on the main line in the relay circuit is also in the normally dropped state; when the first train route is set for the XJC signal, the relay XJC-A / BYXJ picks up, and the relay XJC-YXJF at the main line station in the interface circuit picks up accordingly; after the last section of the first train route is unlocked, it returns to the dropped state.
