Description

Technical Field

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

[0002] The railway train dispatching system is an information system used to monitor, command and control railway train operations. It provides decision support for dispatchers by collecting, processing and analyzing information such as train shunting operation status, line conditions, signal equipment, etc., and realizes real-time monitoring and optimization of train shunting operation control. The train dispatching system is of great significance for optimizing transportation resource allocation, improving transportation efficiency, and solving problems such as daily transportation organization and train safety in emergencies.

[0003] Railway skylights refer to the time period reserved for construction and maintenance work when train lines are not drawn or adjusted or reduced in the train operation diagram. During this time period, no trains pass through the blocked section of the line, and railway staff can enter the line for maintenance or equipment repair work. Skylights are divided into V-shaped skylights and vertical skylights according to the scope of influence.

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

[0005] Vertical skylight: In double-track sections, the up and down lines are blocked and disabled at the same time to form a rectangular gap, which is suitable for operations that need to affect the up and down line driving equipment at the same time.

[0006] The train dispatching system must not only ensure the safety of daily railway transportation organization, but also ensure the fulfillment and safe implementation of the construction skylight, including the electrical test verification during the skylight period. The person responsible for the early acceptance management and daily operation and maintenance of the train equipment is the electrical personnel, and after delivery, it is operated and used by the train personnel for train control. After delivery, the electrical personnel can only directly operate the train equipment to perform complete skylight operations under the vertical skylight, when the up and down lines of the station are completely closed for construction and the train personnel have no train control needs. During the V-shaped skylight period, it is difficult for the electrical personnel to perform construction operations and test verification. Taking the suspension of the up line as an example, during the skylight operation, the train personnel can still operate the receiving and dispatching operations on the down line, and the electrical personnel can operate the maintenance operations on the up line. At present, there is only one operation terminal of the train dispatching system, and the objects of the up and down lines are integrated together. When the train personnel receive and dispatch the train or go out, the electrical personnel can only wait, and the maintenance operation can be verified when the train personnel are free, which seriously affects the construction and maintenance efficiency of the electrical personnel. Therefore, it is of practical significance to design and implement the electrical operation terminal and related systems for electrical personnel to control the driving equipment under the V-shaped skylight, improve the efficiency of V-shaped skylight operation, and reduce the impact of electrical skylight experiments on vehicle personnel's operations. Currently, there are mainly two solutions.

[0007] Solution 1: The electrician and the train crew share a set of train control terminals, and the electrician is constrained by technical regulations and operating specifications during the V-shaped skylight period. For example, the literature: Zhang Tongqiang. Research on the mental workload of station attendants at existing busy trunk lines of railways [D]. Tsinghua University, 2012. mentioned that the electrician and the train crew share a set of train control terminals, and the train crew needs to face one or several work tasks.

[0008] In Plan 1: the electrical personnel and the train personnel share a set of train control terminals, such as the station train terminal. During the V-shaped skylight period, the train personnel operate the train operation in the non-blocked area. When the train personnel are idle and on duty, the electrical personnel operate the train control terminal to perform intermittent experimental verification. Once the train personnel have an emergency to deal with or need to go out of the post, the electrical personnel must immediately interrupt the experiment, give up the equipment control authority, and let the train personnel handle the event or suspend the experimental verification. When the event is handled or the train personnel return to work and there is no other train business, the electrical personnel can continue the experiment.

[0009] However, the defects of Scheme 1 are as follows: (1) The priority of train operation is higher than that of electrical test. The electrical personnel need to wait for the train personnel to be free before they can use the train operation equipment for intermittent test verification. Moreover, the electrical test is easily interrupted by sudden / emergency events of train operation, resulting in low efficiency of the electrical test and difficulty in guaranteeing effective window time. (2) A single terminal cannot distinguish between operators, and cannot effectively record operations and divide responsibilities. (3) A single terminal has complete control rights, which may lead to the risk of misoperation (such as the electrical personnel operating the train operation equipment in an unblocked area). (4) The scheme does not have the function of station status snapshot and comparison, which may lead to the risk that the experimental equipment in the construction area is not reset after the electrical test is completed. (5) The electrical personnel and train personnel need to frequently switch working positions (one person works while the other needs to give up the workbench), which may cause many inconveniences in the idle and small station operation room.

[0010] Solution 2: Split out two sets of train control terminals, and let the train operators and electrical operators operate their own terminals to conduct independent train operations and electrical experiments. For example, in the Chinese invention patent "Station centralized display and control method, equipment and medium based on CTC3.0" with the authorization announcement number CN114296422B, the train terminal can centrally display the station display of multiple stations, and realize the central station to centrally control the station equipment and route sequence of multiple stations. "Combined with the situation mentioned in Solution 1 that there are several defects in the electrical and train operators sharing a set of train control terminals, it is natural to consider arranging two sets of train terminals, one of which is provided to the electrical operators to complete the electrical experiments.

[0011] In the second solution, a complete set of train service terminals is added to the station extension interface server of the existing train dispatching system. During the V-shaped skylight period, the electrician operates the newly added train service terminal, and the train service personnel operate the existing train service terminal, respectively, to conduct electric service experiments and train operation in the closed area and the unclosed area. In fact, both sets of terminals have complete control rights, and external operation specifications are required to restrict personnel to operate only within the scope of authority, and no operation behavior that affects the business of the other end is allowed.

[0012] Compared with Scheme 1, the continuity and effectiveness of the electrical experiment in Scheme 2 are guaranteed, but due to the excessive expansion of permissions, new problems are introduced: (1) The full permissions of the two terminals can easily lead to cross-border operations, cross-interference between electrical experiments and train operations, resulting in the impact on train operations or the introduction of hidden risks in train operations. (2) The full permissions of the train terminal are exposed to electrical personnel, and the complicated operation interface reduces the simplicity and direction of electrical experiments, increases the difficulty of learning for electrical personnel, and increases the risk of misoperation by electrical personnel. (3) There is also no snapshot and comparison function of the station status, and there is a hidden danger that the experimental equipment in the construction area is not reset after the electrical experiment is completed. Summary of the invention

[0013] The purpose of the present invention is to provide an electrical operation terminal and related systems for controlling vehicle equipment under a V-shaped sunroof. Electrical personnel can freely arrange experimental content on an independent terminal without being restricted by vehicle personnel / operations. Each operator only operates within the scope of their respective authority, which can ensure operational safety and prevent illegal / dangerous operations that affect the opposite area.

[0014] The objective of the present invention is achieved through the following technical solutions: A railway traffic dispatching system comprises: a central dispatching system, an external system and a station dispatching system, wherein the station dispatching system comprises: an electric operation terminal and a train operation terminal; wherein: Before construction under the V-shaped skylight, the configuration files generated by dividing the station area are pre-stored in the electrical operation terminal and the vehicle operation terminal. The vehicle operation terminal has the control right of the entire station area, while the electrical operation terminal has no control right; During the construction period under the V-shaped skylight, after the central dispatching system marks a certain area of ​​the station as a blocked area, the electric service operation terminal sends a control right request for the blocked area to the vehicle service terminal in combination with the configuration file; if the electric service operation terminal receives a consent receipt from the vehicle service terminal, it means that the vehicle service terminal transfers the control right of the area to the electric service operation terminal, and then the electric service operation terminal controls the driving equipment in the area with control right in combination with the station status snapshot and comparison function configured by itself, and completes the electric service experiment; The electric service operation terminal periodically sends permission maintenance heartbeat information to the vehicle service terminal; when the vehicle service terminal times out and fails to receive the permission maintenance heartbeat information from the electric service operation terminal, or receives a control termination message sent by the electric service operation terminal, the control interaction under the V-shaped sunroof is terminated.

[0015] An electrical operation terminal for controlling train 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 dispatching system for controlling train equipment and completing electrical experiments.

[0016] It can be seen from the technical solution provided by the above invention that by adding some terminals (i.e., electrical operation terminals), the control and experimental functions of the driving equipment by the electrical personnel under the V-shaped skylight can be realized. At the same time, the station 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 electrical experiment is completed; and a regional control authority interaction mechanism is provided to realize dynamic division of authority, so that each operator can only work within the scope of their respective authority, which can ensure operational safety. In general, the present invention improves the execution efficiency of the V-shaped skylight operation and reduces the impact of the electrical skylight experiment on the operation of the vehicle personnel.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0022] The following is a detailed description of an electric service operation terminal and related systems for controlling a V-shaped sunroof driving device provided by the present invention. The contents not described in detail in the embodiments of the present invention belong to the prior art known to professionals in the field. If no specific conditions are specified in the embodiments of the present invention, the conventional conditions in the field or the conditions recommended by the manufacturer shall be followed. If the manufacturer of the instruments used in the embodiments of the present invention is not specified, they are all conventional products that can be purchased commercially.

[0023] Embodiment 1 The embodiment of the present invention provides a railway traffic dispatching system, such as Figure 1 As shown, it mainly includes: a central dispatching system, an external system and a station dispatching system. Both the central dispatching system and the external system are existing systems, and the present invention will not elaborate on them; the station dispatching system also belongs to the existing system, which includes: a tracking server, a signalman terminal, an autonomous machine, and a vehicle terminal. On this basis, the present invention adds an electrical operation terminal to realize the independent control function of the electrical personnel and vehicle personnel on the station's operating equipment under the V-shaped skylight; at the same time, the existing vehicle terminal and signalman terminal have also been modified in a matching manner. The overall workflow can be described as follows: before the construction under the V-shaped skylight, the configuration file generated by dividing the station area is pre-stored in the electric operation terminal and the vehicle terminal. The vehicle terminal and the signalman terminal have the control right of the entire station area, and the electric operation terminal has no control right; during the construction period under the V-shaped skylight, after the central dispatching system (dispatch console) marks a certain area of ​​the station as a blocked area, the electric operation terminal sends a control right request for the blocked area to the vehicle terminal in combination with the configuration file; if the electric operation terminal receives a consent receipt from the vehicle terminal, it means that the vehicle terminal transfers the control right of the area to the electric operation terminal, and then the electric operation terminal controls the driving equipment in the area with control right and completes the electric experiment in combination with the station status snapshot and comparison function configured by itself; the electric operation terminal sends heartbeat information to the vehicle terminal regularly to maintain the control right of the blocked area; when the vehicle terminal does not receive the heartbeat information from the electric operation terminal after timeout, or receives the control right termination message sent by the electric operation terminal, the control interaction under the V-shaped skylight is terminated.

[0024] Preferably, the vehicle service terminal will periodically send heartbeat information to the remaining terminals, and the heartbeat information carries information about the areas where the remaining terminals have control rights. The remaining terminals confirm the areas where they have control rights based on the heartbeat information from the vehicle service terminal; wherein the vehicle service terminal and the signalman terminal are both configured as master-slave, and the vehicle service terminal that interacts with the electrical operation terminal is the vehicle service terminal host, and the remaining terminals mentioned here include: a vehicle service terminal standby machine and a signalman terminal master-slave machine; when the control interaction under the V-shaped skylight is ended, the vehicle service terminal sends control authority update information to the remaining terminals, the control rights are reset, and the vehicle service terminal and the signalman terminal obtain control rights over all areas of the station.

[0025] In the embodiment of the present invention, before construction, the train service terminal has the control right of the complete area; during the construction period, the train service terminal transfers the control right of the blocked area, but still retains the control right of the non-blocked area; after the construction is completed, the train service terminal takes back the control right of the electrical operation terminal and restores the control right of the complete area, which also includes the control right of the blocked area. In addition, under normal circumstances, the train service terminal and the signalman terminal are the driving control equipment used by the station train staff in daily driving, and have the control right of the complete area. The two terminals generally perform different operations according to the division of business, such as the train service terminal performs the route sequence confirmation operation, and the signalman terminal performs the signal opening operation, both of which are operations on the same (complete) area.

[0026] In the embodiment of the present invention, the electric service operation terminal is connected to the extension server of the station in communication, and the extension server is used to forward the data stream between the electric service operation terminal, the train terminal and the signalman terminal; the data stream includes: control right request, heartbeat information sent by the train terminal and heartbeat information sent by the train terminal. Generally speaking: each terminal is generally interconnected in the form of a network socket, the station extension server is the transfer center of the station, the station equipment network is connected to the station extension server, and the station extension server performs information transfer and distribution.

[0027] Preferably, independent of Figure 1 In addition to the production system structure, the system provides auxiliary tools: the station object splitting tool, which is used to divide the station into different areas, and generate corresponding configuration files and provide them to the electrical operation terminal and the vehicle operation terminal.

[0028] Preferably, the working process of the station object splitting tool includes: preliminary selection of areas in the station through human-computer interaction, and then fine-tuning the station objects through human-computer interaction to achieve the calibration of the downlink area and the uplink area; grouping and naming the downlink area and the uplink area respectively, and making each station object in a single group, and finally forming a configuration file. The configuration file serves as the basis for the electric operation terminal and the vehicle operation terminal to divide the control area.

[0029] Those skilled in the art can understand that the human-computer interaction method refers to the site object splitting tool performing relevant operations according to the received user instructions.

[0030] Preferably, the electrical operation terminal is also used to receive and display station status information, and to manipulate the interlocking equipment in the area with control authority according to input instructions, so as to control the driving equipment and complete electrical experiments.

[0031] The above system provided by the embodiment of the present invention realizes the control and experimental functions of the driving equipment by the electricians under the V-shaped skylight by adding an electrician operation terminal. At the same time, it configures the station status snapshot and comparison function to avoid the hidden danger that the experimental equipment in the construction area is not reset after the electrician experiment is completed; and provides a regional control authority interaction mechanism to realize dynamic authority division, so that each operator can only work within the scope of their respective authority, which can ensure the safety of operation. In general, the present invention improves the execution efficiency of the V-shaped skylight operation and reduces the impact of the electrician skylight experiment on the operation of the vehicle personnel.

[0032] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the system provided by the embodiment of the present invention is described in detail with reference to a specific embodiment below.

[0033] 1. Introduction to the overall system structure.

[0034] See also Figure 1 The overall structure mainly adds an electrical operation terminal to realize the independent control function of the station's operating equipment by the electrical / train personnel under the V-shaped skylight. The electrical operation terminal is connected to the station's extension server for communication, and realizes data and business interaction with other subsystems in the station through the extension server, including the train terminal and autonomous machine.

[0035] (1) Scope of impact: Figure 1 The system shown only needs to add an electrical operation terminal and adapt and modify the vehicle terminal and signalman terminal. Other parts including autonomous machines, extensions, tracking servers, etc. do not need to be modified.

[0036] (2) In terms of data flow, it is only necessary to add a new permission interaction data flow between the electric operation terminal and the train operation terminal through the extension server. Other functions, including the electric operation terminal receiving the station status and the electric operation terminal sending control commands to the autonomous machine, are all existing functions of the extension server or the train dispatching system.

[0037] (3) In terms of project promotion, when introducing the electric service operation terminal into the construction, it is only necessary to upgrade the train terminal / signalman terminal and add new connected users (electric service operation terminal users) to the extension server.

[0038] The present invention makes little structural change to the existing vehicle dispatching system, and the construction has a small impact range. In particular, no modification is required to the autonomous machine and tracking of the core vehicle control terminal, and the equipment and external system of the central dispatching system also do not need to be modified. The project development cycle is short, economical and affordable, and the difficulty of going online is low, which is conducive to on-site promotion.

[0039] 2. Basic data management of stations.

[0040] The operation areas of train and electric personnel under the V-shaped skylight are divided according to up and down directions, and some multi-directional stations may involve more area divisions. To this end, the present invention provides a station object splitting tool to achieve station basic equipment object splitting, as well as data production, verification, maintenance and management functions.

[0041] like Figure 2 As shown, an example of splitting the basic data of a station is provided. Without loss of generality, the area is divided according to the uplink and downlink, that is, the dotted line in the middle of the figure. The upper part of the dotted line is the downlink area of ​​vehicle control, and the lower part of the dotted line is the uplink area of ​​electrical control.

[0042] The station object splitting tool opens the station static data, performs rough area selection (multi-object selection) by multi-selecting with the mouse, and then fine-tunes by adding, deleting, and adjusting a single object to achieve the functions of selecting the upper downward area of ​​the dotted line and calibrating the lower upward area of ​​the dotted line in the diagram. After confirming the calibration of each area, the configuration file VobjGroupCfg.ini is automatically output (the configuration file name is only an example). The objects that need to be split include station yard sections, non-turnouts, tracks, turnouts, train shunting signals, and train shunting buttons. About the station object splitting and file output functions: (1) Each split area can be grouped and named. For example, it can be the upper and lower areas mentioned above. Of course, some special site types or complex large sites may be split into multiple areas, such as 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 about each object.

[0043] (2) Each object in the station yard is only allowed to be in one group. Objects that do not belong to any group are assigned to the train control equipment (train terminal / signalman) for use.

[0044] (3) After the split, the groups form a configuration file VobjGroupCfg.ini. The file name and file format (suffix) are only examples, and they can be used to record group information.

[0045] For the linkage turnout groups that belong to different areas after splitting, each area can handle the route through the turnouts in its own area, but it cannot affect the turnout status of the other area. Figure 2For example, the 1# turnout and 3# turnout in the figure belong to the up and down areas respectively. The down area terminal can handle the route through the 1# turnout, but cannot handle the business involving any objects in the up area (including the 3# turnout), that is, the down area can only handle the 1# turnout positioning route.

[0046] In addition to object splitting and configuration file output, the site object splitting tool can also verify and view the split objects. The tool provides a simple verification method, such as clicking the up and down area buttons to highlight the selected area objects and display the unselected areas in dark colors. The light and dark display is only an example, and the area object identification function can also be viewed by only displaying the objects in this area.

[0047] 3. Design and implementation of electrical operation terminals.

[0048] The electrical operation terminal is deployed in the station operation room and runs on a newly added physical machine or reuses an existing machine (with low hardware resource requirements). The electrical operation terminal does not start running under normal circumstances. During the V-shaped skylight construction experiment phase, the electrical operation terminal is started to realize the control and experimental verification functions of the driving equipment in the construction blockade area. The electrical operation terminal does not receive the dispatching command information and stage plan information of the driving dispatching system, and does not have the route sequence display and control function. The main functions of the electrical operation terminal include: (1) Station display function, including the real-time operating status of station equipment, interlocking status (such as turnout reverse position, signal light position, interlocking routing, etc.), and train tracking display function.

[0049] (2) Interlocking equipment control functions, including turnout operation (single operation, single sealing, single locking), signal machine light-on and light-off operation, button routing, section three-point inspection and other interlocking operations. The electrical operation terminal retains the expansion capability, and CTC operation functions (such as poor branching, anti-slip, power outage and other setting functions) can be realized according to demand in the future. Both the electrical operation terminal and the train operation terminal must perform interlocking operations and CTC operations within the terminal authority area according to the construction scope, authority interaction and configuration files. Operations in each area shall not affect the operation of the opposite terminal through factors such as interlocking turnouts, protective turnouts, and 301 train shunting safety card control.

[0050] (3) Login and operation record function. During project deployment, the electrical operation terminal is normally in the shutdown state. After the electrical operation terminal is started, it receives the user name and password entered by the operator (electrical personnel), and logs into the railway train dispatching system after verification. After that, it can send a control request for the blocked area according to the operator's instructions, and control the train equipment according to the operator's instructions, and complete the electrical experiment. Among them, the user name and password are uniformly verified through the remote database in the form of extension network interaction, or are pre-stored in the local area in ciphertext (such as hard disk files or registry) and verified directly locally. In addition, the login information of the electrical operation terminal and various operation records during the operation process are sent to the maintenance station of the train dispatching system in the set protocol format for storage and later responsibility determination. The maintenance station here includes the central main maintenance station and the station sub-maintenance station, which are responsible for the status monitoring and process recording functions of the train dispatching system.

[0051] (4) Snapshot and comparison functions. After startup and at key time nodes, the electric service operation terminal automatically stores the status of the station signal equipment (and supports manual storage of the current station signal equipment status). When exiting or at the next key time node (or manually selecting the comparison time), it can (automatically or manually) compare the current station signal equipment status with the previously stored station signal equipment status, output the corresponding change status, and highlight the change status of the relevant equipment.

[0052] Among them, weight factors (weight values) are marked for interlocking operation events that affect driving safety and efficiency. If the weighted value (sum of weight values) of the interlocking operation events that occur from the start or the last critical time node to the current moment exceeds the set threshold, it indicates that the current moment is a critical time node.

[0053] As shown in Table 1, an example of the default comparison content is provided. In actual engineering applications, due to different line conditions and construction test requirements at each station, the system can supplement the comparison content of other equipment states that are not reflected (such as: switch position, alarm light color, etc.) according to the needs of the railway bureau.

[0054] Table 1: Equipment status comparison content

[0055] 4. Regional control authority interaction plan.

[0056] In the embodiment of the present invention, the authority interaction process between the electric operation terminal and the station control terminals (train operation terminal, signalman terminal, etc.) of other train dispatching systems is defined: 1. The dispatching system center draws a V-shaped construction symbol, and the dispatching command station issues a construction dispatching order. The center dispatcher manually (by phone or other means) notifies the station construction personnel.

[0057] 2. The electrical personnel starts the electrical operation terminal, enters the user name and password, logs into the system, and the system automatically sends a login confirmation message to the maintenance station.

[0058] 3. The electrician operates the electrician operation terminal and applies to the vehicle terminal for control of the blocked area (taking the blockade of the uplink construction as an example) by right-clicking the alarm light (pre-defined uplink and downlink permission lights) or left-clicking the menu. If the vehicle terminal host refuses, the interaction ends and the electrician operation terminal cannot perform the electrician experiment in the uplink area; if the vehicle terminal host agrees, the vehicle terminal records the success of this interaction and the electrician operation terminal can control the downlink area. The electrician operation terminal confirms that it can control the uplink area based on the interaction consent receipt.

[0059] In the embodiment of the present invention, the vehicle service terminal is configured with a master and a slave, and this part mainly sends an application to the vehicle service terminal host.

[0060] 4. After the interaction is completed and control is obtained, the electrical operation terminal can conduct electrical experiments and use snapshot and comparison functions to ensure that the electrical experiments do not affect actual driving operations.

[0061] 5. During the operation of the electric operation terminal, heartbeat information is sent to the vehicle terminal host at regular intervals to maintain the uplink control of the terminal. The vehicle terminal host immediately and regularly sends heartbeat information to the other control terminals (the heartbeat includes the control area of ​​each terminal). The other control terminals include: vehicle terminal standby terminal (B machine), signalman terminal main and standby terminals (A machines and B machines). The other terminals confirm the control range of the terminal based on the heartbeat information.

[0062] 6. When the vehicle service terminal times out and fails to receive the heartbeat information from the electrical operation terminal, or receives a control termination message sent by the electrical operation terminal, the control interaction under the V-shaped skylight is terminated, and new control authority update information is sent to the remaining terminals to reset the control rights of each terminal in the system.

[0063] 7. Both the electrical operation terminal and the vehicle operation terminal can actively end the control interaction under the V-shaped sunroof without the other party's consent.

[0064] 8. When the vehicle service terminal loses the message of ending the control interaction under the V-shaped skylight under abnormal circumstances, the electric service operation terminal will continue to send the permission to maintain the heartbeat information under normal working conditions. Since the vehicle service terminal host has confirmed the end of the control interaction under the V-shaped skylight, when it receives the permission to maintain the heartbeat information from the electric service operation terminal, it immediately sends the end command of the control interaction under the V-shaped skylight again to confirm that the control interaction under the V-shaped skylight can be ended in time under abnormal network packet loss.

[0065] Figure 3The data flow of the power operation terminal interacting with other vehicle control terminals is shown. In this process, the power operation terminal only interacts with a single terminal (the vehicle terminal host in the figure below).

[0066] In the embodiment of the present invention, the dynamic application of the electric operation terminal and the vehicle operation terminal is retained in the future, and the functions of dynamically adjusting the authority area and the range of controllable objects are adjusted. For example, through reasonable protocol design, the electric personnel can block the downlink IG track and perform electric test functions.

[0067] 5. Other terminal adaptability modifications.

[0068] To implement the present invention, existing driving control terminals such as vehicle operation terminals and signalman terminals need to be adaptively modified: (1) Cooperate with the electric service operation terminal to realize the regional control authority interaction service, including the authority application / approval interaction service of the vehicle service terminal, the authority maintenance heartbeat service, and the authority (forced) termination service.

[0069] (2) Implement the safety card control function of operating only within the control area during the V-shaped skylight according to the configuration file output by the splitting tool. As mentioned above, the control area is determined by the permission interaction business and the configuration file.

[0070] Embodiment 2 An embodiment of the present invention also provides an electrical operation terminal for controlling train equipment under a V-shaped skylight, which runs in a new physical machine or an existing machine in the form of a software program, and is arranged in the station dispatching system of the railway train dispatching system provided in the aforementioned embodiment, for controlling train equipment and completing electrical experiments.

[0071] Considering that the electric service operation terminal and its interaction with other terminal permissions have been introduced in detail in the above embodiments, they will not be described in detail.

[0072] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
