Description

Technical Field

[0001] The present invention relates to the technical field of railway train operation dispatching, and particularly to a signal operation terminal and related system for controlling train operation equipment under a V-shaped skylight. Background Art

[0002] A railway train operation dispatching system is an information system for monitoring, commanding, and controlling railway train operations. By collecting, processing, and analyzing information such as the running status of trains and shunting operations, line conditions, and signal equipment, it provides decision-making support for dispatchers and realizes real-time monitoring and optimization functions for the control of train and shunting operations. The train operation dispatching system is of great significance for optimizing the allocation of transport resources, improving transport efficiency, and solving problems such as daily transport organization and train operation safety in case of emergencies.

[0003] A railway skylight refers to a time period reserved in the train operation diagram without drawing train operation lines or adjusting / deducting train operation lines for construction and maintenance operations. During this time period, there are no trains passing through the blocked section of the line, and railway staff can enter the line for maintenance or equipment repair work. According to the affected scope, skylights are divided into V-shaped skylights and vertical skylights.

[0004] V-shaped skylight: In a double-track section, a "V"-shaped gap is formed in the operation diagram according to the up and down directions of the lines, which is suitable for operations that do not affect the operation of trains in the other direction.

[0005] Vertical skylight: In a double-track section, the up and down lines are blocked and deactivated simultaneously to form a rectangular gap, which is suitable for operations that need to affect the train operation equipment on the up and down main lines simultaneously.

[0006] The train operation dispatching system should not only ensure the safety of daily railway transportation organization, but also ensure the fulfillment and safe implementation of construction skylights, including the verification of signal and communication experiments during skylights. The early acceptance management and daily operation and maintenance of train operation equipment are the responsibilities of signal and communication personnel. After delivery, the equipment is operated by train operation personnel for train operation control. After delivery, signal and communication personnel can only directly operate the train operation equipment for complete skylight operations during vertical skylights when the up and down lines of the station are completely closed for construction and train operation personnel have no need for train operation control. During V-shaped skylights, it is difficult for signal and communication personnel to carry out construction operations and experimental verifications. Taking the suspension of operations on the up line as an example, during skylight operations, train operation personnel can still operate train receiving and dispatching operations on the down line, while signal and communication personnel operate maintenance operations on the up line. Currently, there is only one operation terminal for the train operation dispatching system, and the objects of the up and down lines are integrated. When train operation personnel are performing train receiving and dispatching operations or are away, signal and communication personnel can only wait and can only conduct experimental verifications of maintenance operations when train operation personnel are free, which seriously affects the construction and maintenance efficiency of signal and communication personnel. Therefore, designing and implementing an operation terminal and related system for signal and communication personnel to control train operation equipment under V-shaped skylights is of practical significance for improving the execution efficiency of V-shaped skylight operations and reducing the impact of signal and communication skylight experiments on train operation personnel's operations. Currently, there are mainly the following two solutions.

[0007] Solution 1: Signal and communication personnel and train operation personnel share a set of train operation control terminals, and the experimental schemes of signal and communication personnel during V-shaped skylights are restricted through technical regulations and operation specifications. For example, as mentioned in the literature: Zhang Tongqiang. Research on the Mental Load of Station Masters on Existing Busy Main Lines of Railways [D]. Tsinghua University, 2012., signal and communication personnel and train operation personnel share a set of train operation control terminals, and train operation personnel need to face one or several work tasks.

[0008] In Solution 1: Signal and communication personnel and train operation personnel share a set of train operation control terminals, such as the train operation terminal at the station. During V-shaped skylights, train operation personnel operate train receiving and dispatching operations in non-blocked areas. During the idle and on-duty period of train operation personnel, signal and communication personnel operate the train operation control terminal for intermittent experimental verifications. Once train operation personnel have an emergency to handle or need to go out and leave their posts, signal and communication personnel need to immediately interrupt the experiment, give up the equipment control authority, and let train operation personnel handle the event or suspend the experimental verification. After the event is handled or train operation personnel return to their posts and there are no other train operation operations, signal and communication personnel can continue the experiment.

[0009] However, the drawbacks of Solution 1 are as follows: (1) The priority of train operation business is higher than that of signal maintenance experiments. Signal maintenance personnel need to wait for train operation personnel to be idle and on duty before they can borrow train operation equipment for intermittent experimental verification. Moreover, signal maintenance experiments are easily interrupted by sudden / urgent train operation events, resulting in low efficiency of signal maintenance experiments and difficulty in ensuring effective skylight time. (2) A single terminal cannot distinguish operators, making it impossible to record operations effectively and divide responsibilities. (3) A single terminal has complete control rights, posing a risk of misoperation (such as signal maintenance personnel operating train operation equipment in an unblocked area). (4) The solution does not have a function of taking snapshots and comparing the station yard status, leaving a hidden danger that the experimental equipment in the construction area is not reset after the signal maintenance experiment. (5) Signal maintenance personnel and train operation personnel need to frequently switch their working positions (when one person is working, the other person needs to vacate the operation console), which causes many inconveniences in the small and idle train operation rooms of some stations.

[0010] Solution 2: Split out two sets of train operation control terminals, and train operation personnel and signal maintenance personnel operate their respective terminals to conduct independent train operation business and signal maintenance experiments. For example, in the Chinese invention patent "Station yard centralized display and control method, equipment and medium based on CTC3.0" with the authorization announcement number CN114296422B, the train operation terminal can centrally display the station yard displays of multiple stations and realize the centralized control of the station yard equipment and route sequences of multiple stations by the central station. Considering the several defects existing in the situation where signal maintenance personnel and train operation personnel share a set of train operation control terminals mentioned in Solution 1, it is natural to consider arranging two sets of train operation terminals, and one set is provided for signal maintenance personnel to complete signal maintenance experiments.

[0011] In Solution 2: On the station sub - interface server of the existing train operation dispatching system, add a complete set of train operation terminals. During the V - type skylight period, signal maintenance personnel operate the newly added train operation terminal, and train operation personnel operate the existing train operation terminal to conduct signal maintenance experiments and train operation business in the blocked area and the unblocked area respectively. In fact, both sets of terminals have complete control rights, and external operation specifications and other means are needed to restrict personnel to operate only within their authority and not to have any operation behaviors that affect the business of the other end.

[0012] Compared with Solution 1, the continuity and execution effectiveness of signal maintenance experiments in Solution 2 are guaranteed, but due to the over - expansion of permissions, new problems are introduced: (1) The complete permissions of the two sets of terminals are extremely likely to lead to out - of - bounds operations, cross - interference between signal maintenance experiments and train operation, resulting in the impact on train operation business or introducing potential risks to train operation. (2) Exposing the complete permissions of the train operation terminal to signal maintenance personnel, the complex operation interface reduces the simplicity and directivity of signal maintenance experiments, increases the difficulty for signal maintenance personnel to learn and get started, and also increases the risk of misoperation by signal maintenance personnel. (3) Similarly, there is no function of taking snapshots and comparing the station yard status, leaving a hidden danger that the experimental equipment in the construction area is not reset after the signal maintenance experiment. Summary of the Invention

[0013] The object of the present invention is to provide a signal operation terminal and related system for controlling train operation equipment under a V-shaped skylight. Signal workers can freely arrange experimental contents on an independent terminal without being restricted by train operation personnel / operations. Each operator only operates within their respective authority ranges, which can ensure operation safety and prevent illegal / dangerous operations that may affect the opposite area.

[0014] The object of the present invention is achieved through the following technical solutions:

[0015] A railway train operation dispatching system includes: a central dispatching system, an external system, and a station dispatching system. The station dispatching system includes: a signal operation terminal and a train operation terminal; wherein:

[0016] Before construction under the V-shaped skylight, both the signal operation terminal and the train operation terminal are pre-stored with a configuration file generated by dividing the station yard area. The train operation terminal has the control right over the entire station yard area, and the signal operation terminal has no control right;

[0017] During the construction period under the V-shaped skylight, after the central dispatching system designates a certain area of the station yard as a blocked area, the signal operation terminal sends a request for the control right of the blocked area to the train operation terminal in combination with the configuration file; if the signal operation terminal receives an approval receipt feedback from the train operation terminal, it means that the train operation terminal transfers the control right of this area to the signal operation. After that, the signal operation terminal performs train operation equipment control and completes signal experiments within the area with the control right in combination with the snapshot and comparison function of the station yard status configured by itself;

[0018] The signal operation terminal regularly sends permission-holding heartbeat information to the train operation terminal; when the train operation terminal does not receive the permission-holding heartbeat information from the signal operation terminal within the timeout period, or receives a control right termination message sent by the signal operation terminal, the control interaction under the V-shaped skylight ends.

[0019] A signal operation terminal for controlling train operation equipment under a V-shaped skylight runs in a newly added physical machine or an existing machine in the form of a software program and is set in the station dispatching system of the aforementioned railway train operation dispatching system for performing train operation equipment control and completing signal experiments.

[0020] It can be seen from the technical solutions provided by the present invention above that by adding some terminals (i.e., signal operation terminals), the function of signal workers controlling train operation equipment and conducting experiments under the V-shaped skylight is realized. At the same time, the snapshot and comparison function of the station yard status is configured to avoid the hidden danger that the experimental equipment in the construction area is not reset after the signal experiment. And a regional control right interaction mechanism is provided to realize dynamic division of permissions, enabling each operator to only operate within their respective authority ranges, which can ensure operation safety. Generally speaking, the execution efficiency of operations under the V-shaped skylight is improved through the present invention, and the influence of signal skylight experiments on train operation personnel operations is reduced.

The content not described in detail in the embodiments of the present invention belongs to the prior art well-known to those skilled in the art.

[0030] Embodiment 1

[0031] An embodiment of the present invention provides a railway train operation dispatching system, as Figure 1 shown, which mainly includes: a central dispatching system, an external system, and a station dispatching system. The central dispatching system and the external system are both existing systems, and the present invention will not elaborate on them; the station dispatching system also belongs to an existing system, which includes: a tracking server, a signalman terminal, an autonomous machine, and a train operation terminal. On this basis, the present invention adds an electrical operation terminal to realize the independent control functions of electrical and train operation personnel for station train operation equipment under the V-shaped skylight; at the same time, the existing train operation terminal and signalman terminal are also modified accordingly. The overall workflow can be described as follows: Before construction under the V-shaped skylight, the electrical operation terminal and the train operation terminal both pre-store the configuration file generated by dividing the station yard area. The train operation terminal and the signalman terminal have the control right of the entire station yard area, and the electrical operation terminal has no control right; during the construction period under the V-shaped skylight, after the central dispatching system (dispatching order desk) identifies a certain area of the station yard as a blocked area, the electrical operation terminal combines the configuration file to send a control right request for the blocked area to the train operation terminal; if the electrical operation terminal receives the consent receipt feedback from the train operation terminal, it means that the train operation terminal transfers the control right of this area to the electrical operation terminal. After that, the electrical operation terminal combines the snapshot and comparison function of the station yard state configured by itself to control the train operation equipment in the area with the control right and complete the electrical experiment; the electrical operation terminal regularly sends heartbeat information to the train operation terminal to maintain the control right of the blocked area; when the train operation terminal does not receive the heartbeat information of the electrical operation terminal within the timeout period, or receives the control right termination message sent by the electrical operation terminal, the control interaction under the V-shaped skylight ends.

[0032] Preferably, the train operation terminal periodically sends heartbeat messages to the other terminals. The heartbeat messages carry the area information over which each of the other terminals has control rights. The other terminals confirm the areas over which they have control rights based on the heartbeat messages received from the train operation terminal. Among them, both the train operation terminal and the signalman terminal are configured with primary and standby units, and the train operation terminal that interacts with the electrical operation terminal is the main unit of the train operation terminal. Herein, the other terminals include: the standby unit of the train operation terminal and the primary and standby units of the signalman terminal. When ending the control interaction under the V-shaped skylight, the train operation terminal sends control right update information to the other terminals, resets the control rights, and the train operation terminal and the signalman terminal obtain the control rights over all areas of the station yard.

[0033] In the embodiment of the present invention, before construction, the train operation terminal has the control rights over the entire area; during the construction period, the train operation terminal cedes the control rights over the blocked area, but still retains the control rights over the non-blocked area; after the construction is completed, the train operation terminal takes back the control rights of the electrical operation terminal and resumes the control rights over the entire area, including the control rights over the blocked area. In addition, usually, the train operation terminal and the signalman terminal are the train operation control devices for the station train operation personnel during daily train operation and have the control rights over the entire area. Generally, the two terminals perform different operations according to the business division of labor. For example, the train operation terminal performs the operation of confirming the route sequence, and the signalman terminal performs the operation of opening the signal. Both are operations on the same (entire) area.

[0034] In the embodiment of the present invention, the electrical operation terminal is communicatively connected to the branch server of the station. The branch server is used to forward the data streams among the electrical operation terminal, the train operation terminal, and the signalman terminal. The data streams include: control right requests, heartbeat messages sent by the train operation terminal, and heartbeat messages sent by the train operation terminal. Generally speaking: each terminal is generally interconnected in the form of a network Socket (socket). The station branch server is the transfer center of the station. The station equipment is network-connected to the station branch server, and the station branch server performs information transfer and distribution.

[0035] Preferably, independent of Figure 1 outside the production system structure, the system provides an auxiliary tool: a station yard object splitting tool, which is used to divide the station yard into different areas, generate corresponding configuration files, and then provide them to the electrical operation terminal and the train operation terminal.

[0036] Preferably, the working process of the station yard object splitting tool includes: initially selecting areas in the station yard through a human-computer interaction method, and then fine-tuning the addition and deletion of station yard objects through a human-computer interaction method to achieve the calibration of the downlink area and the uplink area; grouping and naming the downlink area and the uplink area respectively, and ensuring that each station yard object is in a single group, and finally forming a configuration file. This configuration file serves as the basis for the electrical operation terminal and the train operation terminal to divide the control areas.

[0037] Those skilled in the art can understand that the human-computer interaction method refers to the operation of the yard object splitting tool according to the received user instructions.

[0038] Preferably, the signal operation terminal is further configured to receive and display the yard status information, and control the interlocking equipment in the area with control authority according to the input instruction, so as to realize train operation equipment control and complete signal experiments.

[0039] The above system provided by the embodiment of the present invention realizes the control and experiment functions of signal personnel on train operation equipment under the V-shaped skylight by adding a signal operation terminal. At the same time, the yard status snapshot and comparison functions are configured to avoid the hidden danger that the experimental equipment in the construction area is not reset after the signal experiment; and a regional control authority interaction mechanism is provided to realize dynamic authority division, so that each operator can only operate within their respective authority ranges, which can ensure operation safety. Generally speaking, the execution efficiency of V-shaped skylight operations is improved through the present invention, and the impact of signal skylight experiments on train operation personnel operations is reduced.

[0040] In order to more clearly show the technical solutions provided by the present invention and the technical effects produced, the system provided by the embodiment of the present invention will be described in detail below with specific embodiments.

[0041] 1. Introduction to the overall structure of the system.

[0042] Also refer to Figure 1 , in terms of the overall structure, a signal operation terminal is mainly added to realize the independent control functions of signal / train operation personnel on the station train operation equipment under the V-shaped skylight. The signal operation terminal is communicatively connected to the branch server of the station, and data interaction and service interaction with other subsystems in the station are realized through the branch server, including the train operation terminal and the self-discipline machine, etc.

[0043] (1) In terms of the influence scope, Figure 1 only the signal operation terminal needs to be added and the train operation terminal and the signalman terminal need to be adapted and modified in the system shown, and no modification is required for other components including the self-discipline machine, the branch, and the tracking server.

[0044] (2) In terms of the data flow, only a new authority interaction data flow between the signal operation terminal and the train operation terminal needs to be added through the branch server. Other functions such as the signal operation terminal receiving the yard status and the signal operation terminal sending control commands to the self-discipline machine are all existing functions of the branch server or the train operation dispatching system.

[0045] (3) In terms of project promotion, during the construction of introducing the signal operation terminal, only the train operation terminal / signalman terminal needs to be upgraded, and at the same time, a new connected user (signal operation terminal user) needs to be added in the branch server.

[0046] The present invention makes minor changes to the structure of the existing train operation dispatching system, with a small construction impact scope. In particular, no modifications are required for the self-discipline machines and tracking of the core train operation control terminals, and neither the equipment of the central dispatching system nor the external systems need to be modified. The engineering development cycle is short, it is cost-effective, and the online implementation difficulty is low, which is conducive to on-site promotion.

[0047] 2. Yard basic data management.

[0048] During the V-shaped skylight period, the operation areas of the station operation personnel and the signal and communication personnel are divided according to the up and down lines. Some multi-direction stations may involve more area divisions. Therefore, the present invention provides a yard object splitting tool to achieve the splitting of yard basic equipment objects, as well as the functions of data production, verification, maintenance, and management.

[0049] As Figure 2 shown, a yard basic data splitting example is provided. Without loss of generality, the area is divided according to the up and down lines, that is, the dotted line in the middle of the figure. The upper part of the dotted line is the down-line area controlled by the station operation, and the lower part of the dotted line is the up-line area controlled by the signal and communication.

[0050] The yard object splitting tool opens the station static data, and conducts a rough area selection (multi-object selection) by multi-selection with the mouse, and then fine-tunes by adding or deleting single objects to achieve the function of selecting the down-line area above the dotted line and calibrating the up-line area below the dotted line in the figure. After confirming the calibration of each area, the configuration file VObjGroupCfg.ini (the configuration file name is only an example) is automatically output. The objects that need to be split include yard sections, non-switch tracks, tracks, switches, train operation signals, and train operation buttons. Regarding the yard object splitting and file output functions:

[0051] (1) Each split area can be grouped and named. For example, it can be the upper and lower two parts of the area described above. Of course, for some special yard types or large and complex yards, it may be split into multiple areas, such as the S area, X area, SW area, etc. The key information of each area includes the area ID, area name, total number of objects in the area, and information of each object.

[0052] (2) Each object in the yard is only allowed to be in one group. Objects that do not belong to any group are assigned to the train operation control equipment (station operation terminal / signalman) for use.

[0053] (3) After splitting, the groups form a configuration file VObjGroupCfg.ini. The file name and file format (suffix) are only examples, as long as the group information can be recorded.

[0054] For the interlocking switch groups that belong to different areas after splitting, each area can handle the routes of the switches passing through this area, but the switch states of the other areas cannot be affected. Take Figure 2Taking the No. 1 turnout and No. 3 turnout as examples, they belong to the up and down line areas respectively. The approach via the No. 1 turnout can be handled at the terminal of the down line area, but the operations involving any objects in the up line area (including the No. 3 turnout) cannot be handled. That is, only the normal position approach of the No. 1 turnout can be handled in the down line area.

[0055] In addition to realizing the object splitting and configuration file output functions, the station yard object splitting tool can also realize the verification of the split objects and the function of viewing the identification. The tool provides simple verification means. For example, by clicking the up and down line area buttons, the highlighted display of the objects in the selected area can be realized, and the unselected area is displayed in dark color. The bright and dark display is only an example, and the function of viewing the area object identification can also be realized by only displaying the objects in this area and other methods.

[0056] 3. Design and implementation of the signal maintenance operation terminal.

[0057] The signal maintenance operation terminal is deployed in the station operation room and runs on a newly added physical machine or reuses the existing machine (with low requirements for hardware resources). The signal maintenance operation terminal does not start running under normal conditions. During the construction experiment stage of the V-shaped skylight, the signal maintenance operation terminal starts to realize the control and experimental verification functions of the train operation equipment in the construction blocking area. The signal maintenance operation terminal does not receive the dispatching command information and stage plan information of the train operation dispatching system, nor does it have the function of displaying and controlling the approach sequence. The main functions of the signal maintenance operation terminal include:

[0058] (1) Station yard display function, including the real-time operation status of the train operation equipment in the station yard, interlocking status (such as the normal and reverse positions of turnouts, the lamp positions of signal lights, the interlocking route arrangement, etc.), and at the same time, the train number tracking display function is carried out.

[0059] (2) Interlocking equipment control function, including turnout operations (single operation, single locking, single blocking), signal light on / off operations, button route arrangement, three-point inspection in the section and other interlocking operations. The signal maintenance operation terminal retains the expansion ability, and the CTC operation function (such as functions of setting shunting defects, anti-rolling, power supply cut-off, etc.) can be realized according to requirements in the future. Both the signal maintenance operation terminal and the station operation terminal need to perform interlocking operations and CTC operations within the terminal permission area according to the construction scope, permission interaction and configuration file. The operations in each area shall not affect the operations of the opposite terminal due to factors such as linked turnouts, protecting turnouts, and 301 train shunting safety control.

[0060] (3) Login and operation record function. During project deployment, the electrical and signal operation terminal is normally in a shutdown state. After the electrical and signal operation terminal is started, it receives the username and password entered by the operator (electrical and signal personnel). After successful verification, it logs in to the railway train operation dispatching system. Then, it can send a request for the control right of the blocked area according to the operator's instructions, control the train operation equipment according to the operator's instructions, and complete electrical and signal experiments. Among them, the username and password are uniformly verified through the remote database in the way of branch network interaction, or are stored locally in ciphertext in advance (such as hard disk files or registry) and directly verified locally. In addition, the login information of the electrical and signal operation terminal and various operation records during the operation process are sent to the maintenance desk of the train operation dispatching system in a set protocol format for storage recording and later responsibility determination. The maintenance desk here includes the central general maintenance desk and the station sub-maintenance desk, which are responsible for the status monitoring and process recording functions of the train operation dispatching system.

[0061] (4) Snapshot and comparison function. After the electrical and signal operation terminal is started and at key time nodes, it automatically stores the status of the station field signal equipment (manual storage of the current station field signal equipment status is also supported). When exiting or at the next key time node (or manually selecting the comparison time), it can (automatically or manually) compare the current station field signal equipment status with the previously stored station field signal equipment status, output the corresponding change status, and highlight the change status of the relevant equipment.

[0062] Among them, weight factors (weight values) are marked for interlocking operation events that affect train operation safety and efficiency. From the start or the previous key time node to the current moment, if the weighted value (sum of weight values) of the interlocking operation events that have occurred exceeds the set threshold, it indicates that the current moment is a key time node.

[0063] As shown in Table 1, an example of the default comparison content is provided. In actual project applications, due to different line conditions and construction experiment requirements of each station, the system can supplement and set the comparison content of other equipment statuses not reflected (such as switch positions, alarm light colors, etc.) according to the needs of the railway administration.

[0064] Table 1: Comparison Content of Equipment Status

[0065]

[0066] 4. Regional control authority interaction solution.

[0067] In the embodiment of the present invention, the authority interaction process between the electrical and signal operation terminal and the station control terminals (train operation terminals, signalman terminals, etc.) of other train operation dispatching systems is defined:

[0068] 1. The central train dispatcher's console in the dispatching system plots the V-shaped construction symbol, and the dispatching order console issues the construction dispatching order. The central dispatcher manually (such as by phone) notifies the construction personnel at the station.

[0069] 2. The signal maintenance personnel start the signal operation terminal. After entering the username and password, they log in to the system, and the system automatically sends a login confirmation message to the maintenance console.

[0070] 3. The signal maintenance personnel operate the signal operation terminal. By right-clicking on the alarm light (pre-defined up / down line authority lights) or left-clicking on the menu, etc., they apply for the control right of the blocked area to the train operation terminal (taking the up-line construction block as an example). If the host of the train operation terminal refuses, the interaction ends, and the signal operation terminal cannot conduct signal experiments in the up-line area; if the host of the train operation terminal agrees, the train operation terminal records the success of this interaction, and the signal operation terminal can control the down-line area. The signal operation terminal confirms that it can control the up-line area according to the interaction consent receipt.

[0071] In the embodiment of the present invention, the train operation terminal has a primary and a standby setting. This part mainly sends an application to the host of the train operation terminal.

[0072] 4. After the interaction is completed and the control right is obtained, the signal operation terminal can conduct signal experiments, and through the snapshot and comparison functions, ensure that the signal experiments do not affect the actual train operation service.

[0073] 5. During the operation of the signal operation terminal, it regularly sends heartbeat messages to the host of the train operation terminal to maintain the up-line control right of this machine. The host of the train operation terminal immediately and regularly sends heartbeat messages to the other control terminals (the heartbeat contains the control areas of each terminal). The other control terminals include: the standby of the train operation terminal (B machine), the primary and standby of the signalman terminal (A machine and B machine). The other terminals confirm the control range of this machine according to the heartbeat message.

[0074] 6. When the train operation terminal does not receive the heartbeat message from the signal operation terminal within the timeout period, or receives the control right termination message sent by the signal operation terminal, it ends the control interaction under the V-shaped skylight and sends a new control right update message to the other terminals to reset the control rights of each terminal in the system.

[0075] 7. Both the signal operation terminal and the train operation terminal can actively end the control interaction under the V-shaped skylight without the consent of the other party.

[0076] 8. When abnormal situations occur such as the loss of messages for the train operation terminal to end the control interaction under the V-shaped skylight, the signal operation terminal will continue to send permission-holding heartbeat information under normal working conditions. Since the train operation terminal host has confirmed the end of the control interaction under the V-shaped skylight, when it receives the permission-holding heartbeat information from the signal operation terminal, it immediately sends the end command for the control interaction under the V-shaped skylight again to confirm that the control interaction under the V-shaped skylight can be ended in a timely manner in case of network packet loss anomalies.

[0077] Figure 3 It shows the data flow of the signal operation terminal interacting with other train control terminals for permission. In this process, the signal operation terminal only interacts with a single terminal (the train operation terminal host in the following figure).

[0078] In the embodiments of the present invention, the functions of the signal operation terminal and the train operation terminal to dynamically apply and dynamically adjust the permission area and the range of controllable objects are retained. For example, through reasonable protocol design, the signal personnel can block the downlink IG track and perform signal experiments.

[0079] 5. Modify the adaptability of other terminals.

[0080] To implement the present invention, existing train control terminals such as the train operation terminal and the signalman terminal need to be modified for adaptability:

[0081] (1) Combine with the signal operation terminal to implement the regional control permission interaction service, including the permission application / approval interaction service, permission-holding heartbeat service, permission (forced) termination service, etc. of the train operation terminal.

[0082] (2) Implement the configuration file output by the splitting tool to achieve the safety control function of only operating within the control area during the V-shaped skylight. As mentioned above, the control area is jointly determined by the permission interaction service and the configuration file.
