[0027] 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 with reference to the accompanying drawings in the present invention. Apparently, 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 without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0028] To better illustrate the technical solutions of the embodiments of the present invention, the relevant technical background of the present invention will be described below first.

[0029] Currently, for two adjacent stations of a tram, single-track operation is adopted between the stations. Referring to Figure 1 the schematic diagram of the single-track section shown, track circuits or axle counters (i.e., track between stations) are installed between the stations. Generally, the following operation requirements and main technical conditions need to be met: 1. When changing the original receiving station to a departure station, as long as the section is idle, the departure route of the original departure station is in the unlocked state, and the original receiving station arranges the departure route. After the departure route is locked, the change of the operation direction is permitted. However, it must be ensured that the original departure route is first changed to a receiving station, and it is not permitted for the two stations to become departure states simultaneously, not even for an instant.

[0030] 2. When there is a train in the section, it is necessary to ensure that all the trains dispatched from the departure station have completely reached the receiving station before allowing the change of the running direction.

[0031] 3. When there is a train in the section, the station can continue to arrange the departure route in the same direction as the train running in the section.

[0032] Currently, the station connection interface of the interlocking system generally uses the inter-station connection circuit as the blocking equipment. This method has problems such as cumbersome interface circuits, large occupied space, and relatively high required equipment costs. Specifically, there are the following problems: 1. If the operation mode between stations adopts double tracks, the floor area is large and the investment is high. 2. If the operation mode between stations adopts single track and the inter-station blocking method is used, only one train can run between stations, and the operation / operating efficiency is low (that is, when there is a train running between stations, other trains are not allowed to run between this section of stations). 3. Since there are a large number of components in the inter-station connection circuit, due to reasons such as equipment aging, this will lead to complex fault troubleshooting, high later maintenance costs, and long maintenance cycles. 4. The inter-station connection circuit has the problem of non-modularity, which will also lead to a long construction period.

[0033] Based on this, the embodiment of the present invention provides a single-track two-way vehicle operation control method, which can solve the above technical problems.

[0034] The following combines Figures 2 - 6 to describe the single-track two-way vehicle operation control method of the embodiment of the present invention.

[0035] It should be noted that the execution subject of the embodiment of the present invention can be the single-track two-way vehicle operation control device of any station, or the electronic device of any station, or other control devices or equipment of any station. Here, no specific limitation is made. The following embodiments will take the electronic device of this station as an example as the execution subject for description.

[0036] Figure 2 is one of the flow diagrams of the single-track two-way vehicle operation control method provided by the present invention. As Figure 2 shown, the method includes the following steps: S102. Obtain the first message sent by the opposite station in the single-track section; the above first message includes the state of the first check relay variable, and the state of the first check relay variable is used to represent whether the opposite station allows this station to dispatch trains to the opposite station.

[0037] Among them, the single-track section refers to that there is only one line or one inter-station track (that is, the track laid on this line) between two adjacent stations, and this line or inter-station track connects these two adjacent stations. Here, this station and the opposite station are two relatively stations. For example, for Figure 1 Station A in, Station A is this station, and Station B is the opposite station. For another example, forFigure 1 For Station B in Figure 1 Figure 1 , Station B is the local station and Station A is the opposite station. Additionally, the stations here can also be referred to as turnout areas or areas under centralized management of turnouts. For example,

[0038] Generally, in a single-track section, station-to-station blocking is adopted for operation. That is, when a vehicle is running on the track between stations, other vehicles are not allowed to run on this section between stations, which will lead to low operation efficiency of vehicles in the single-track section. To solve this problem, in this step, a check relay variable (denoted as ZCJ) can be set for each of the two stations in the single-track section in advance, that is, one check relay variable is set for one station. This check relay variable has two states: picked up and dropped (or called disconnected). Among them, different states represent different meanings, specifically used to indicate whether the local station allows the opposite station to send a train to the local station. The dropped state of the check relay variable indicates that the local station does not allow the opposite station to send a train to the local station, and the picked-up state indicates that the local station allows the opposite station to send a train to the local station. Among them, the check relay variable of the opposite station is denoted as the first check relay variable, and the check relay variable of the local station is denoted as the second check relay variable.

[0039] The above two stations can communicate and interact through a communication gateway. During the process of actually realizing train departure at the local station, it is necessary to combine relevant information detected at the local station, interlocking information, etc., and at the same time, it is also necessary to combine the state of the first check relay variable of the opposite station. Based on this, in the embodiment of the present invention, the local station can interact with the opposite station to receive a message sent by the opposite station, denoted as the first message. The first message may include the state of the first check relay variable of the opposite station, and of course, it may also include other information.

[0040] For the format of the first message, for example, it can be referred to as shown in Table 1 below.

[0041] Table 1

[0042] Among them, the local station in Table 1 refers to the station that sends the first message, that is, actually the opposite station itself in this embodiment. The check (1~N) ID in this Table 1 refers to the identifier of different check relay variables. Generally, each line of each station corresponds to a check relay variable, and N refers to the identifier of the line, generally greater than or equal to 1. In this embodiment, if it is a single-track section, the first message may only include one check relay variable and its related information.

[0043] In addition, the above Table 1 is an example of the message protocol format for the interaction of check information between the two stations. Through this message protocol format, the following functions are mainly realized: 1. Through the message header, you can effectively check whether the message information is correct and whether the sending order is normal.

[0044] 2. Through the data part of the message, take station A as an example. When station A receives a message from station B, if station A needs to check the status of the corresponding check 1 of station B before it can send a vehicle, when it is checked that the status of check 1 is down, it means that there is a vehicle at station B sending a vehicle to this station, then station A cannot arrange the departure route and cannot send a vehicle to station B. When the status of check 1 is up, station A can arrange the departure route. When the interlocking conditions of the continuous departure process and normal inspection are met, station A arranges the departure route and can send a vehicle to station B.

[0045] 3. The occupancy status of the station track ZJG in the message can prevent axle counting failures. Station A and Station B will send their acquired ZJG status to each other. When the ZJG status of this station is inconsistent with the status received in the message, the ZJG status of this station can be set to occupied according to the principle of guiding the safety side.

[0046] 4. The status of the receiving signal corresponding to the section of this station is transmitted to the other station. The dispatcher can see the status of the receiving signal of the other station through the meter operating machine of this station, which is convenient for dispatching operations.

[0047] S104, if it is determined based on the state of the first check relay variable that the opposite station allows the station to send a train to the opposite station, then the power-on unlocking state of the station is obtained; the power-on unlocking state includes the station being in the power-on unlocking state or the station not being in the power-on unlocking state.

[0048] In this step, as mentioned above, the communication gateway of this station can receive the first message sent by the opposite station, and forward the first message to the main control module (logic operation module, that is, electronic device) of this station. The main control module parses the first message to obtain the state of the first check relay variable included therein, that is, the check 1 state in the above table, and the check 1 state includes suction or drop.

[0049] If the state of the first check relay variable is down, it means that the opposite station does not allow this station to send trains to the opposite station. At this time, this station cannot arrange the departure route to send trains to the opposite station.

[0050] If the state of the first check relay variable is attracted, it means that the opposite station allows the station to send trains to the opposite station, then the station can obtain the power-on unlocking state of the station itself, that is, determine whether the station is in the power-on unlocking state. Here, it is assumed that the station is in the power-on unlocking state, that is, the station is in the reset state. If the power-on unlocking state is not released, all operations in the station cannot be carried out.

[0051] In addition, during the specific process of dispatching trains at this station, the station can first obtain a list of check relay variables of this station. The list of check relay variables includes at least one check relay variable and the line / section corresponding to each check relay variable for checking. Then, when dispatching a train for a certain line, it can check whether there is a check relay variable corresponding to this line in the list of check relay variables. If there is a check relay variable corresponding to this line, it can check the power-on unlocking status of this station, that is, determine whether this station is in the power-on unlocking state. If this station is in the power-on unlocking state, the status of the check relay variable corresponding to this line of this station is set to drop, that is, it is not allowed for the opposite station to dispatch trains to this station, thus ensuring the safety of vehicle operation. For example, if Station B is in the power-on unlocking state, the check relay variable of Station B is set to drop, and at this time, Station A cannot dispatch trains to Station B.

[0052] S106. If the power-on unlocking status is that this station is not in the power-on unlocking state, obtain the occupancy status of the track between this station and the opposite station and the occupancy status of the target section between this station and the opposite station; the target section is the last section of the departure route of this station or the first section of the receiving route.

[0053] In this step, if the judgment result obtained after judging whether this station is in the power-on unlocking state is that this station is not in the power-on unlocking state, that is, this station may be in operation. To facilitate the operation of multiple trains in a single-track section, in this step, the occupancy status of the track between this station and the opposite station (denoted as ZJG) can be continuously obtained, and the occupancy status of the target section between this station and the opposite station can be obtained. Generally, the track between stations may be divided into multiple sections. Here, the target section can be the last section of the departure route of this station or the first section of the receiving route of this station. The departure route is the route for dispatching trains to the opposite station, and the receiving route is the route for receiving trains dispatched from the opposite station.

[0054] Among them, the occupancy status of the track between stations includes the track between stations being occupied or the track between stations being idle (i.e., not occupied). The occupancy status of the track between stations detected by this station can be determined by the identifier of the track between stations displayed on the operation table machine (station connection operation interface) of this station. For example, if the identifier of this track between stations is lit, it means the track between stations is occupied, and if the identifier of this track between stations is off, it means the track between stations is idle. Similarly, the occupancy status of the target section can include the target section being occupied or the target section being idle, and the occupancy status of the track between stations detected by this station can also be determined by the identifier of the target section displayed on the operation table machine (station connection operation interface) of this station. For example, if the identifier of this target section is lit, it means the target section is occupied, and if the identifier of this target section is off, it means the target section is idle.

[0055] S108, if at least one of the occupancy status of the track between stations and the occupancy status of the target section is occupied, control this station to continue dispatching trains to the opposite station.

[0056] In this step, if either the track between stations or the target section is occupied, or both the track between stations and the target section are occupied, it indicates that there is a train running on the current single-track section. Generally, the running train is the one dispatched from this station according to the above judgment. If the status of the first check relay variable of the opposite station is picked up, that is, this station is allowed to dispatch trains to the opposite station, then this station can continue to arrange the departure route and continue to dispatch trains to the opposite station, as long as the running interval between adjacent trains is well controlled. That is to say, this station can continuously dispatch trains to the opposite station without waiting for the track between stations and / or the target section to be cleared before continuing to dispatch trains, thus achieving the purpose of running multiple trains in one direction on the single-track section.

[0057] Similarly, for the opposite station, it can also be regarded as this station to execute the above steps of this embodiment to obtain the result of whether it can continuously dispatch trains to its opposite station, thereby achieving the purpose of two-way and multi-train operation on the single-track section and improving the operation / operation efficiency of the vehicles on the single-track section.

[0058] In this embodiment, by obtaining the first message sent by the opposite station in the single-track section, which includes the status of the first check relay variable, and obtaining the power-on unlocking status of this station when it is determined that the opposite station allows this station to dispatch trains to the opposite station according to the status of the first check relay variable. If the power-on unlocking status is that this station is not in the power-on unlocking state, obtain the occupancy status of the track between this station and the opposite station and the occupancy status of the target section between this station and the opposite station, and control this station to continue dispatching trains to the opposite station when at least one of these two occupancy statuses is occupied; wherein, the status of the first check relay variable is used to represent whether the opposite station allows this station to dispatch trains to the opposite station, the power-on unlocking status includes that this station is in the power-on unlocking state or this station is not in the power-on unlocking state, and the target section is the last section of the departure route of this station or the first section of the receiving route. In this method, since it is possible to quickly and accurately know whether the opposite station allows this station to dispatch trains to it through the check relay variable in the message sent by the opposite station, and when the opposite station allows this station to dispatch trains and this station is not in the power-on unlocking state, by judging that at least one of the occupancy status of the track between this station and the departure section or the receiving section is occupied, this station is allowed to continue dispatching trains to the opposite station, so that the purpose of running multiple trains simultaneously in one direction on the single-track section can be achieved, that is, the vehicle operation efficiency on the single-track section can be improved.

[0059] The following embodiments illustrate the process of determining the locked state of the departure route of this station before obtaining the occupied states of the inter-station track and the target section between this station and the opposite station respectively.

[0060] In some embodiments, before the step of "obtaining the occupied state of the inter-station track between this station and the opposite station and the occupied state of the target section between this station and the opposite station" in S106 above, the method may further include the following steps: Determine whether there is a target route according to the departure route list of this station; the departure route list includes at least one route for this station to depart to the opposite station, and the target route is the departure route for which the status of the second checking relay variable needs to be checked, and the status of the second checking relay variable is used to indicate whether this station allows the opposite station to depart to this station; If there is a target route and the station corresponding to the target route is not in the state of unlocking after power-on, set the locked state of the departure route of this station to departure locked and set the status of the second checking relay variable to dropped.

[0061] Among them, the departure route list of this station is an arranged departure route list, that is, all existing routes of this station, including at least one arranged departure route for this station to depart to the opposite station, and the identifiers of different routes are different. In advance, a checking relay variable can be set for some departure routes with checking requirements, and a checking relay variable does not need to be set for departure routes without checking requirements. Here, the checking requirement means that the departure route needs to determine whether to turn on or off the light according to the status of the checking relay variable.

[0062] After arranging the departure route list above, the departure routes in the departure route list can be checked, and it can be obtained whether there is a departure route that requires a checking relay variable through the previous setting. If there is, mark the existing departure route as the target route, and at the same time check whether this station is in the state of unlocking after power-on. If it is not in the state of unlocking after power-on (i.e., not unlocked), the locked state of the departure route of this station can be set to departure locked (for example, if the locked state of the departure route of this station here can be marked as flag 1, then the status of flag 1 can be set to departure locked), and at the same time, the status of the second checking relay variable can be set to dropped, that is, this station can depart to the opposite station through this target route.

[0063] Optionally, if there is no target route, set the locked state of the departure route of this station to departure unlocked; if the locked state of the departure route is departure unlocked, determine the status of the second checking relay variable according to the occupied state of the inter-station track, the occupied state of the target section, and the interlocking state of this station.

[0064] That is to say, if there is no route that needs to check the variables of the check relay, it means that there may be no vehicles sent from this station to the opposite station through the track direction between single-track stations. At this time, the locking state of the departure route of this station can be set to departure unlocking. At this time, the occupancy state of the inter-station track, the occupancy state of the target section, and the interlocking state of this station can be combined to determine the state of the second check relay variable of this station. The interlocking state here can include when the departure route is arranged, when the departure route is unlocked, when the interlocking of this station is powered on and unlocked, when the departure route of this station is not arranged (the vehicle occupying the inter-station track ZJG is not sent from this station), and after the interlocking of this station is powered on and unlocked.

[0065] For example, taking this station as an example, for several situations of the state of the second check relay variable of this station (i.e., the holding state of ZCJ), the interlocking check condition table shown in Table 2 below can be referred to.

[0066] Table 2

[0067] The interlocking system or the main control module of this station can periodically determine the state of the second check relay variable through the above input conditions and the interlocking state, and change the state of the second check relay variable ZCJ itself according to the determined state. The state of the ZCJ variable is determined according to the input conditions obtained by the main control calculation of this station and sent to the opposite station through the network.

[0068] In this embodiment, before obtaining the occupancy states of the inter-station track and the target section respectively, the locking state of the departure route of this station can also be determined, specifically by whether there is a route that needs to check the variables of the check relay. In this way, the locking state of the departure route of this station can be accurately and quickly determined, and then the state of the corresponding check relay variable can be set to ensure the train operation safety in the single-track section. In addition, when the departure route of this station is unlocked, the occupancy state of the inter-station track, the occupancy state of the target section, and the interlocking state of this station can be combined to determine the state of the second check relay variable of this station. In this way, the state of the check relay variable of this station can be accurately determined, further ensuring the train operation safety in the single-track section.

[0069] In some embodiments, refer to Figure 3The schematic flowchart for checking whether the departure route meets the arrangement requirements as shown. In this embodiment, it is also possible to check whether the departure route of this station meets the arrangement requirements. The specific checking process is as follows: First, the return value can be set to "check passed", and then all interlocking devices are traversed (i.e., all interlocking relay variables. In advance, all the interlocking relay variables of this station can be grouped together) to determine whether there is a network interlocking device that matches the incoming route (i.e., to determine whether there is a corresponding interlocking relay variable for the departure route in the departure route list). If not, the process ends directly; if there is an interlocking device, it is determined whether the interlocking device is within the departure route. If not, the process ends directly; if it is within the departure route, it is determined whether the state of the interlocking device is picked up. If it is not picked up but dropped, the process ends directly. If it is picked up, the occupancy status of the interlocking section (between stations) and the target section is obtained and it is determined whether they are occupied. If they are occupied, "check not passed / error" is returned, and this station will not arrange the departure route. Otherwise, "departure route allows arrangement" is returned.

[0070] In this embodiment, by checking whether the departure route of this station meets the arrangement requirements, misarrangement of the departure route can be avoided, ensuring the safety of two-way train operation in a single-track section.

[0071] The following embodiments illustrate the situation where neither the inter-station track nor the target section is occupied.

[0072] In some embodiments, the above method may further include the following steps: If both the occupancy status of the inter-station track and the occupancy status of the target section are idle, the state of the second interlocking relay variable of this station is set to picked up; the above-mentioned picked up is used to indicate that this station allows the opposite station to send a train to this station; The state of the interlocking relay variable of this station is encapsulated in the second message and sent to the opposite station.

[0073] Among them, if the interlocking state of this station is after power-on unlocking, that is, not in the state when power-on unlocking, or this station has not arranged a departure route (the vehicle occupying ZJG is not sent from this station), at this time, if this station detects that both the occupancy status of the inter-station track and the occupancy status of the target section are idle, it means that there is temporarily no vehicle running between this station and the opposite station. At this time, the state of the second interlocking relay variable of this station can be set to picked up, that is, allowing the opposite station to send a train to this station.

[0074] If the interlocking state of this station is in the departure route arrangement state, at this time, if it is detected that both the occupancy status of the inter-station track and the occupancy status of the target section are idle, it means that this station is in the process of sending a train. At this time, the state of the second interlocking relay variable needs to be set to dropped, that is, not allowing the opposite station to send a train to this station.

[0075] Of course, the status of the second check relay variable of this station can also be determined under various conditions according to the input conditions in Table 2 above and the interlocking status of this station. Generally, the status of the second check relay variable is fixed at a certain moment. After determining the status of the second check relay variable at a certain moment, the main control module of this station can encapsulate the status of the second check relay variable in a message, form a second message, and send it to the opposite station through the communication gateway, so that the opposite station can timely learn whether this station allows the opposite station to depart and make a timely response, improving the safety of single-track two-way multi-vehicle operation.

[0076] In this embodiment, by determining the status of the second check relay variable of this station and forming a second message to send to the opposite station, it is convenient for the opposite station to timely learn whether this station allows the opposite station to depart and make a timely response, improving the safety of single-track two-way multi-vehicle operation.

[0077] The following embodiments will illustrate the process of determining the status of the second check relay variable when this station is in the power-on unlocking state.

[0078] In some embodiments, the above method may further include the following steps: If the power-on unlocking state is that this station is in the power-on unlocking state, obtain the occupancy status of the above inter-station track and the occupancy status of the target section; If at least one of the occupancy status of the inter-station track and the occupancy status of the target section is occupied, set the status of the second check relay variable of this station to drop; dropping is used to indicate that this station does not allow the opposite station to depart to this station.

[0079] Among them, this station can detect whether the power-on unlocking flag exists. If it exists, it means that this station has just completed the power-on unlocking at this time, that is, when this station is in the power-on unlocking state, it is necessary to check the occupancy status of the inter-station track and the occupancy status of the target section at this time. If at least one of the two is occupied, that is, there is a vehicle driving between this station and the opposite station, and at this time it is impossible to determine whether the vehicle has left this station or a vehicle has just entered this station.

[0080] For the safety of train operation, at this time, it is necessary to set the status of the second check relay variable of this station to drop, that is, not to allow the opposite station to depart to this station.

[0081] In this embodiment, when this station has just completed the power-on unlocking, if at least one of the inter-station track and the target section is occupied, it is necessary to set the status of the check relay variable of this station to drop in order to prohibit the opposite station from departing to this station and ensure the safety of train operation in the single-track section.

[0082] The following embodiments illustrate the process of determining the state of the second check relay variable of this station when the state of the first check relay variable sent to the opposite station is dropped.

[0083] In some embodiments, the above method may further include the following steps: If it is determined according to the state of the first check relay variable that the opposite station does not allow this station to depart to the opposite station, then set the state of the second check relay variable of this station to dropped; dropped is used to indicate that this station does not allow the opposite station to depart to this station; Determine to prohibit arranging a departure route from this station to the opposite station.

[0084] Among them, after parsing the first message, if the obtained result includes that the state of the first check relay variable of the opposite station is dropped, at this time, it can be determined that the opposite station does not allow this station to depart to it. At this time, in order to ensure train operation safety, the state of the second check relay variable of this station can be set to dropped, that is, if the state of the second check relay variable of this station is dropped, then continue to maintain the dropped state. If the state of the second check relay variable of this station is picked up, then update the state of the second check relay variable to dropped.

[0085] After maintaining or updating the state of the second check relay variable of this station to dropped, it is also necessary to prohibit this station from continuing to arrange a departure route, that is, it cannot continue to arrange a departure route.

[0086] In this embodiment, when the state of the first check relay variable sent by the opposite station is dropped, the state of the second check relay variable of this station can be set to dropped, which can ensure train operation safety within a single-track section.

[0087] The following embodiments illustrate the process of determining the state of the second check relay variable when the inter-station track occupancy status determined by this station is inconsistent with the inter-station track occupancy sent by the opposite station.

[0088] In some embodiments, the above method may further include the following steps: Receive the occupancy status of the inter-station track sent by the opposite station, and obtain the occupancy status of the inter-station track detected by this station; If the occupancy status of the inter-station track sent by the opposite station is inconsistent with the occupancy status of the inter-station track determined by this station, then set the state of the second check relay variable of this station to dropped; dropped is used to indicate that this station does not allow the opposite station to depart to this station.

[0089] Among them, this station can receive the occupancy status of the inter-station track sent by the opposite station at regular intervals or periodically. The occupancy status of the inter-station track sent by the opposite station is obtained by the opposite station's own measurement. The occupancy status of the inter-station track sent by the opposite station can be sent to this station by the opposite station alone through a message, or carried in the first message and sent to this station. For example, the occupancy status of the inter-station track detected by the opposite station is carried in the first message shown in Table 1 above. For example, the "status of the inspection 1 section" among them is the status of the inter-station track ZJG obtained / detected by the opposite station itself.

[0090] At the same time, this station itself can also detect the occupancy status of the inter-station track at regular intervals, periodically or in real time, and obtain the occupancy status of the inter-station track detected by itself. Then this station can compare the occupancy status of the inter-station track detected by itself with the occupancy status of the inter-station track sent by the opposite station. If the two are inconsistent, it means that there may be a fault in the inter-station track or a detection error in any one of the stations. At this time, according to the safety-oriented principle, it is necessary to set the status of the second inspection relay variable of this station to drop, that is, the opposite station is not allowed to send a train to this station to ensure the train operation safety in this section. If the occupancy status of the inter-station track detected by this station itself is consistent with the occupancy status of the inter-station track sent by the opposite station, it means that the train operation is normal, and at this time, trains can be sent or received normally.

[0091] In this embodiment, when the occupancy status of the inter-station track determined by this station is inconsistent with the occupancy status of the inter-station track sent by the opposite station, the status of the second inspection relay variable of this station is set to drop, which can ensure the train operation safety in this single-track section.

[0092] To facilitate a better understanding of the technical solutions of the embodiments of the present invention, a detailed embodiment is given below. Refer to Figure 4 the continuous train departure service flow chart shown. The continuous train departure process of this station is as follows: A vehicle or the dispatching sends an instruction to arrange a train departure route to the main control. When the ZCJ (inspection relay variable) of the opposite station is pulled up, this station starts to arrange the train departure route. If the conditions are met, the departure signal is opened to allow the vehicle to leave this station and drive towards the opposite station. During the opening of the signal, the route conditions are checked in real time. When the signal opening conditions are not met (for example, when a vehicle enters the train departure route and there is a problem in the route that does not meet the continued opening of the signal), the signal is closed.

[0093] During the train departure process of this station, refer to Figure 5Schematic diagram of the continuous departure check relay variable detection process shown. After starting the departure, it is possible to traverse the check relay variables of this station (i.e., traverse the check devices). When there are no check devices in the section network, continue to traverse the check devices of this station; when there are check devices in the section network, it is possible to determine whether this station is in the power-on unlocking state, and when it is in the power-on unlocking state, set the state of the ZCJ (check relay variable) of this station to drop. When this station is not in the power-on unlocking state, it is possible to check the occupancy status of the inter-station track between this station and the opposite station and the occupancy of the last section of the departure route of this station, and when there is at least one occupancy, set the state of the ZCJ (check relay variable) of this station to drop. When there is no occupancy, determine whether this station is not in the power-on unlocking state, and when it is not in the power-on unlocking state, set the state of the ZCJ (check relay variable) of this station to pick up, and then set the check flag of this station to not check; or when it is in the power-on unlocking state, directly set the check flag of this station to not check.

[0094] When this station is not in the power-on unlocking state, if the occupancy status of the inter-station track and the occupancy of the last section of the departure route of this station are not checked, the departure route lock state flag can be set to unlocked. At the same time, traverse the dynamic route table (departure route table), and when there is a check in the route, obtain the number of sections in the route. Then traverse the sections, obtain the section numbers and determine whether the sections belong to the turnout sections. When the section belongs to the turnout section, the section is locked and not released in the route, set the lock state flag of the departure route to locked, and update the timestamp of the departure route lock state. Then subtract one from the traversed section number and continue to return to traverse the sections; when the section does not belong to the turnout section or is not section-locked and not released in the route, subtract one from the traversed section number and continue to return to traverse the sections.

[0095] After the dynamic route table traversal is completed, set the occupancy status of the section between stations / tracks between stations and the occupancy flag of the last section of the departure route of this station to unoccupied. Then, when the departure route is locked, determine whether the section between stations / tracks between stations and the last section of the departure route of this station are occupied. When occupied, set the occupancy status of the section between stations / tracks between stations and the occupancy status of the last section of the departure route of this station, and when not occupied, set the departure route status to unlocked. When the departure route is not locked, continue to determine whether the departure route locking flag is locked. When it is not locked, set the departure route locking status to locked, and continue to determine whether the section between stations / tracks between stations is occupied, whether the first section inside the receiving signal of this station is occupied, and whether the departure is locked. When the judgment result is yes, set the status of the ZCJ (check relay variable) of this station to drop; or when the judgment result is no, determine whether the delayed unlocking is completed. If so, set the status of the ZCJ (check relay variable) of this station to pick up. If not, return to continue traversing the check equipment, and end the process after the traversal of the check equipment of this station is completed.

[0096] Through the above-mentioned check process for continuous departures, even if the departure route of this station is unlocked and the train is in the section, the check relay variable of the departure station remains dropped, so that when the train of the departure station has not reached the opposite station but the departure route of this station is unlocked, the departure route can be arranged continuously to send a train to the opposite station, thus realizing the function of multi-train operation on a single-track section of a full electronic interlocking system.

[0097] For the entire business process, that is, there is only a single track in the main line turnout section and there is a demand for two-way departures. The operation scenarios can be summarized into 9 business scenarios. The operation of the route can be controlled by the status of the check relay variable (ZCJ) to achieve the goal of protecting the trains sent from the opposite station when the ZJG (track between stations, there is only one axle counter section between stations) is occupied and ensuring that the trains in the departure direction can continuously send trains to the ZJG.

[0098] Continue with Figure 1 Taking Station A and Station B in Scenario 1: After the interlocking system of Station A is restarted (Station A enters the power-on unlocking state), if the ZJG is occupied or there is a section occupied on the departure route of Station A, the ZCJ of Station A drops and no departure route can be arranged for Station A.

[0099] Scenario 2: After the interlocking system of Station B is restarted (Station B enters the power-on unlocking state), if the ZJG is occupied or there is a section occupied on the departure route of Station B, the ZCJ of Station B drops and no departure route can be arranged for Station B.

[0100] Scenario 3: After the interlocks at both Station A and Station B are restarted simultaneously (both Station A and Station B enter the electrolytic unlocking state), if ZJG is occupied or there is a section occupied on the departure route of this station, then the ZCJ at both Station A and Station B drops, and no departure route can be arranged to Station A and Station B. Only after ZJG becomes idle can the ZCJ pick up.

[0101] Scenario 4: When the ZCJ of this station picks up, the opposite station can arrange a departure route to this station; when this station handles a departure route and the route is locked, the ZCJ of this station drops, and the opposite station cannot arrange a departure route to this station.

[0102] Scenario 5: After the departure route is unlocked, if the status of ZJG or the first section inside the receiving signal is occupied, the ZCJ remains dropped. It is not until the status of both ZJG and the first section inside the receiving signal of this station (the last section of the departure route) becomes clear that the ZCJ picks up.

[0103] Scenario 6: When the ZCJ of this station picks up and ZJG is occupied, this station cannot arrange a departure route. For example: when the ZCJ of Station A and Station B picks up and ZJG is clear, if ZJG suddenly becomes occupied, neither Station A nor Station B can arrange a departure route to the opposite station.

[0104] Scenario 7: This station has arranged a departure route to the opposite station, the ZCJ of this station drops, and ZJG is in a clear state. At this time, ZJG suddenly becomes occupied. The ZCJ of this station continues to remain dropped, and the departure is not affected.

[0105] Scenario 8: When this station successfully handles a departure route and the ZCJ drops, if the check relay at the receiving station drops, then the departure signal of this station cannot be opened (it must be extinguished if opened) and an alarm will be prompted.

[0106] Scenario 9: When there is no departure route at this station and a section included in the departure route is occupied, at this time, the adjacent station can handle a departure route to this station under the condition of meeting the interlock conditions.

[0107] As can be seen from the descriptions of the above embodiments, in the embodiments of the present invention, the function of two-way multi-train operation in a single-track section of a full-electronic interlock can be realized through software logic. Specifically, the multi-train operation in the single-track section can be controlled by information such as the status of the check relay variable, the occupancy status of the track between stations, and the occupancy status of the last section of the departure route. In addition, in the embodiments of the present invention, information interaction between two stations can also be realized through a network protocol. See Figure 6Schematic diagram of the station network architecture shown, where each of the two stations is provided with an operation table machine with a station connection operation interface, a main control module including a logical operation module, and a communication gateway. Messages between the two stations can be exchanged through the communication gateways of the two stations, and the messages are check interaction information sent through the network.

[0108] During the departure process, through the above network structure, information interaction between two stations can be realized, specifically including information interaction in each stage of route establishment, signal opening, section clearing, and route unlocking, and the signal machine control method of this station. In this way, the function of multi-vehicle operation in a single-track section can be realized in a fully software digital manner, thus solving the problem that the multi-vehicle operation in a single-track section of a tram currently must adopt the section blocking method, and having the technical effects of improving the operation efficiency of the tram, reducing the floor area, reducing the equipment investment cost, being easy to construct and debug, reducing the housing requirements, having lower later use and maintenance costs, and being easy to expand, and the interaction information can be flexibly customized.
