[0044] CTCS (Chinese Train Control System) is a train operation control system that is designed to ensure safe train operation and meet the transportation needs of different lines in a graded manner. According to different lines, different information transmission methods and blocking technologies, CTCS is divided into five levels, namely CTCS0-CTCS4. Multiple application levels can be implemented on the same line, with downward compatibility to meet the speed requirements of different lines.

[0045] Among them, the CTCS2 train control system is the most widely used signal system in my country's high-speed railways, and has been widely used in trunk railways and intercity railways. The CTCS2 train control system is a point-to-point system based on point-to-point transponders and track circuits to transport train operation control information. It is basically divided into on-board systems and ground systems, of which the ground system includes the train control center, interlocking, temporary speed limit server, centralized dispatching system, track circuits and transponders. The train control center is an important ground equipment, which provides driving information such as messages and codes to the on-board ATP (Automatic Train Protection), interlocking to achieve interlocking relationships between stations and depots, establish routes, control the switching of switches and the opening of signals, and unlock routes to ensure driving safety.

[0046] The train control center and interlocking can meet the needs of stations and transportation operations of various sizes, ensure driving safety, and have large amounts of information and networking capabilities. The integrated train control and interlocking system integrates the functions of the train control center system and the computer interlocking system. The system can use electronic execution units to directly control trackside equipment such as transfer machines, signal machines, transponders, track circuits, etc., and also has the function of interfacing with trackside equipment and other equipment through relay interfaces. The integrated train control and interlocking system can effectively reduce the number of ground signal system equipment and external interfaces between systems, improve system safety, and reduce the complexity of the ground signal system and the maintenance cost throughout the life cycle.

[0047] At present, when maintenance, inspection or sudden failure is required between two stations, the whole station protection method is adopted for protection. Specifically, the integrated train control and interlocking system of the two stations and all other equipment between the two stations are disabled. The impact range of this protection method includes the section between the two stations and other areas under the jurisdiction of the integrated train control and interlocking system of the two stations, and the impact range is large.

[0048] To this end, the present application provides a protection method, device and integrated train control interlocking system for reducing the impact range of the protection.

[0049] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0050] See also Figure 1 and Figure 2 ,in, Figure 1 A flowchart of a protection method provided by an embodiment of the present application is shown. Figure 2 A structural schematic diagram of the train control interlocking integrated system provided by an embodiment of the present application is shown. A protection method provided by an embodiment of the present application, each section is respectively provided with a corresponding relay, each relay is respectively connected to the train control interlocking integrated system through a drive system, and the protection method is applied to the train control interlocking integrated system, which may include:

[0051] S11: Acquire the status of the relays corresponding to each section from each driving and mining system, and determine the prohibited passage information of each section according to the status of the relays corresponding to each section.

[0052] Each section of the train control system (specifically, the railway line between two adjacent stations) is divided into multiple sections. In the embodiment of the present application, each section in each section can be respectively provided with a corresponding relay, and the relay corresponding to each section is respectively connected to the train control interlocking integrated system through the drive and mining system. It should be noted that the train control system where the train control interlocking integrated system in the embodiment of the present application is located can be a CTCS-0 level train control system or a CTCS-2 level train control system, and the drive and mining system can specifically be an IO drive and mining system. Among them, each section can be respectively provided with a relay to be connected to the corresponding drive and mining system, or each section can also be respectively provided with at least two corresponding relays, one of which is connected to the train control interlocking integrated system as a main relay through the corresponding drive and mining system, and the remaining relays are used as standby relays. When the main relay fails, one of the available standby relays can be replaced as the main relay to be connected to the corresponding train control interlocking system to improve reliability.

[0053] When a certain section or certain sections suddenly fails or is otherwise abnormal, or when maintenance or overhaul is required for a certain section or certain sections, the corresponding relays of the corresponding sections can be controlled to act (for example, the corresponding relays can be controlled to fall). A control device connected to the relays corresponding to the corresponding sections can be provided, and the control device automatically controls the action of the relays corresponding to the corresponding sections, or the action of the relays corresponding to the corresponding sections can be manually realized.

[0054] Each drive and mining system can respectively collect the state of the relay corresponding to the corresponding section at a fixed time or in real time (specifically, it can be divided into the suction state and the drop state), and can send the collected state of the relay corresponding to the corresponding section to the train control interlocking integrated system, so that the train control interlocking integrated system can obtain the state of the relay corresponding to each section. Among them, after the drive and mining system obtains the state of the relay corresponding to the corresponding section, it can first perform analog-to-digital conversion on the obtained state of the relay corresponding to the corresponding section, so as to convert the state of the relay corresponding to the corresponding section from an analog signal to a digital signal, and then send it to the train control interlocking integrated system, so that the train control interlocking integrated system can determine the prohibited passage information of the corresponding section based on the state of the relay corresponding to the corresponding section in the form of a digital signal.

[0055] Specifically, after the train control interlocking integrated system obtains the state of the relay corresponding to each section from each drive and mining system, it can determine the prohibited passage information of each section according to the corresponding relationship between the stored relay state and the prohibited passage information of the section and the state of the relay corresponding to each section obtained from each drive and mining system. For example, the corresponding relationship between the relay state and the prohibited passage information of the section can be that the relay falling state corresponds to the section prohibited passage information is valid, and the relay lifting state corresponds to the section prohibited passage information is invalid. Of course, it can also be other corresponding relationships. Among them, the prohibited passage information is valid, indicating that the section needs to be prohibited, and the prohibited passage information is invalid, indicating that the section does not need to be prohibited.

[0056] S12: Determine the prohibited area according to the prohibited passage information of each section, and set the prohibited area.

[0057] After the train control interlocking integrated system determines the prohibited passage information of each section according to the state of the relay corresponding to each section, it can determine the scope of the prohibited passage area according to the prohibited passage information of each section. Specifically, it can determine the scope of the prohibited passage area according to whether the prohibited passage information of each section is valid. After determining the prohibited passage area, the prohibited passage area can be set so that the prohibited passage area has a prohibited passage function.

[0058] S13: The information of the prohibited area is sent to the on-board equipment of the train through the track circuit, and the on-board equipment controls the train operation according to the information of the prohibited area; wherein, when the train is outside the prohibited area, the train is prohibited from entering the prohibited area; when the train is traveling in the prohibited area, the train is controlled to stop by emergency braking; when the train stops in the prohibited area, the train is prohibited from starting.

[0059] After setting the forbidden area, the integrated train control and interlocking system can send the information of the forbidden area to the on-board equipment on the train through the track circuit. Then, the on-board equipment on the train can control the operation of the train where the on-board equipment is located according to the information of the forbidden area, so that the forbidden area set by the integrated train control and interlocking system can actually take effect. Specifically, when the train is outside the forbidden area, the train can be prohibited from entering the forbidden area. Specifically, the permitted end point of the train can be controlled to be the entrance of the forbidden area, that is, the train can be controlled to stop at the entrance of the forbidden area; when the train is running in the forbidden area, the train is controlled to stop by emergency braking so that the train no longer moves; when the train stops in the forbidden area, the train is prohibited from starting, so that the forbidden area set by the integrated train control and interlocking system can play the forbidden function, that is, the forbidden area set by the integrated train control and interlocking system can actually take effect, thereby ensuring the driving safety of the train and the working safety of the on-site staff.

[0060] Compared with the current method of achieving full station protection by disabling the integrated train control interlocking system at both ends of the section and all other equipment in the section, the embodiment of the present application sets corresponding relays in each section of the section, determines the prohibited passage information of the section according to the state of the relay, determines and sets the prohibited passage area according to the prohibited passage information of the section, and allows the on-board equipment to control the operation of the train according to the information of the prohibited passage area to limit the protection range to the set prohibited passage area (specifically, limit the protection range to the section where the prohibited passage information is valid), so as to reduce the protection impact range, thereby improving the train passage efficiency and protection efficiency, and reducing the protection cost. And through the above process, the automatic setting of the prohibited passage area by using the integrated train control interlocking system is realized, so as to save labor costs, reduce economic losses caused by sudden accidents, improve operational efficiency, and bring significant economic benefits.

[0061] In addition, through the above process, the integrated train control and interlocking system has the function of setting a prohibited area. Specifically, when a certain area needs maintenance, overhaul or a sudden failure occurs, the corresponding area can be set as a prohibited area through the above process. That is, compared with the current integrated train control and interlocking system, the embodiment of the present application adds a function of setting a prohibited area to the integrated train control and interlocking system based on its existing functions. When a certain area needs maintenance, overhaul or a temporary failure occurs, the integrated train control and interlocking system can set the area as a prohibited area. Figure 3As shown, it shows a schematic diagram of the functions of the integrated train control and interlocking system provided in the embodiment of the present application, which may specifically include: route control, turnout control, signal control, interlocking logic operation, track circuit processing, dual-machine switching, dual-machine synchronization, section block partition occupancy logic check, platform door control and protection, track circuit coding, station signal degradation, temporary speed limit processing and signal degradation processing, station repeater function, section signal lighting, section direction control, transponder message control and prohibited area setting function.

[0062] In the above technical solution disclosed in the embodiment of the present application, each section is respectively provided with a corresponding relay, and the relay corresponding to each section is respectively connected to the train control interlocking integration through the driving and mining system. The train control interlocking integration system obtains the status of the relay corresponding to each section from the driving and mining system, determines the prohibited passage information of each section according to the status of the relay corresponding to each section, and determines the prohibited passage area and sets the prohibited passage area accordingly. Then, the information of the prohibited passage area is sent to the on-board equipment through the track circuit to control the prohibition of trains outside the prohibited passage area from entering the prohibited passage area, the emergency braking and stopping of trains running in the prohibited passage area, and the prohibition of starting of trains parked in the prohibited passage area, so as to ensure the driving safety of the train and the working safety of the staff in the prohibited passage area. Through the above process, the protection range is limited to the set prohibited passage area by using the train control interlocking integration system, so that the protection influence range can be reduced and the train passage efficiency can be improved.

[0063] See also Figure 4 and Figure 5 ,in, Figure 4 It shows the schematic diagram of the prohibited area code provided by the present application. Figure 5 A schematic diagram of setting a prohibited area provided in an embodiment of the present application is shown. A protection method provided in an embodiment of the present application, setting a prohibited area, may include:

[0064] Set an H code for the prohibited area, and set an information code for the rear section of the prohibited area according to the H code of the prohibited area;

[0065] The information of the prohibited area is sent to the on-board equipment of the train through the track circuit, which may include:

[0066] The H code of the prohibited area and the information code of the section behind the prohibited area are sent to the track circuit, and then sent to the rails of the corresponding section by the track circuit, so that the on-board equipment of the train can obtain the information code of the current section through the rails of the current section, and control the train operation according to the information code of the current section.

[0067] In the embodiment of the present application, the specific process of setting the prohibited area by the train control interlocking integrated system can be: setting the determined prohibited area as H code, and setting the information code for the rear section of the prohibited area according to the H code set for the prohibited area and the tracking code issuance sequence. In the aforementioned process, the prohibited area is set according to the permitted end point, that is, the permitted end point of the train is the entrance of the prohibited area, that is, the driving permission of the rear train is to the starting point of the prohibited area.

[0068] In the above-mentioned information codes, the H code indicates that emergency stopping measures are required immediately. The rear section of the prohibited area is determined according to the running direction of the train, such as Figure 4 As shown, the tracking and coding sequence is: L5→L5→L4→L3→L2→L→LU→U→HU→H, L5 means that there are at least 7 free block sections ahead of the train, L4 means that there are 6 free block sections ahead of the train, L3 means that there are 5 free block sections ahead of the train, L2 means that there are 4 free block sections ahead of the train, L means that there are 3 free block sections ahead of the train, LU means that there are 2 free block sections ahead of the train, U means that there is 1 free block section ahead of the train, and HU means that parking measures are required in a timely manner. By setting the H code for the restricted area and setting the information code for the section behind the restricted area according to the tracking and coding sequence and the H code of the restricted area, the train movement authorization point is calculated to facilitate the control of train operation. It should be noted that Figure 4 The white unfilled area (the area in the rectangle and the area in the circle) can be specifically corresponding to green, the horizontal line filled area (the area in the rectangle and the area in the circle) can be specifically corresponding to yellow, and the oblique line filled area (the area in the rectangle and the area in the circle) can be specifically corresponding to red. Figure 5 The two circles in the middle represent traffic lights. The circles filled with slashes represent that the traffic lights are red. The black bold lines at the blocked restricted areas correspond to red, indicating restricted areas.

[0069] On the basis of the above, when the integrated train control and interlocking system sends the information of the prohibited area to the on-board equipment of the train through the track circuit, it can specifically send the H code of the prohibited area and the information code of the section behind the prohibited area to the track circuit, and the track circuit sends the H code of the prohibited area and the information code of the section behind the prohibited area to the rails of the corresponding sections respectively, so that the on-board equipment of the train can obtain the information code of the section where the train is currently located through the rails of the section where the train is currently located, and control the operation of the train according to the information code of the section where the train is currently located. For example, when the information code of the section where the train is currently located is L5 code, the train can be controlled to continue to run at the specified speed. When the information code of the section where the train is currently located is HU code, the train can be controlled to take stopping measures in time. When the information code of the area where the train is currently located is H code (i.e., prohibited area), the train is controlled not to move (specifically, the train traveling in the prohibited area is controlled to emergency brake and stop, and the train that has stopped in the prohibited area is not allowed to start). Among them, in the aforementioned process, specifically, the TCR (TrackCircuit Reader) in the on-board equipment of the train obtains the information code of the current section of the train through the rails of the current section of the train, and first performs analog-to-digital conversion on the information code of the current section of the train to convert it into a digital signal and then sends it to the control module in the on-board equipment. The control module in the on-board equipment controls the train according to the information code of the current section of the train.

[0070] Through the above process, the protection range can be accurately limited to the prohibited area, so as to reduce the impact range when dealing with maintenance, inspection or sudden failures, improve train operation efficiency and reduce protection costs.

[0071] A protection method provided in an embodiment of the present application may further include: when setting an H code for a prohibited area and setting an information code for a rear section of the prohibited area according to the H code of the prohibited area.

[0072] Set the status of the signal corresponding to the corresponding section.

[0073] In the embodiment of the present application, when the train control interlocking integrated system sets an H code for the prohibited area and sets an information code for the section behind the prohibited area according to the H code of the prohibited area, the state of the signal corresponding to the corresponding section can be set according to the information code set for each section. For example, for the prohibited area with the information code of the H code, the state of the corresponding signal is set to red light, indicating a prohibited signal. For details, see Figure 4 , Figure 4 The circle on the left side of the corresponding section represents the traffic light.

[0074] By setting the status of the signal lights corresponding to the corresponding sections, train operation information is transmitted to the driver and train dispatcher, so as to accurately display the command line, shunting orders, etc.

[0075] A protection method provided in an embodiment of the present application may further include:

[0076] The H code of the prohibited area, the information code of the section behind the prohibited area and the status of the signal corresponding to the corresponding section are sent to CTC.

[0077] After setting the H code for the restricted area, setting the information code for the section behind the restricted area, and setting the status of the signal corresponding to the corresponding section, the integrated train control and interlocking system can send (specifically, send in real time) the H code of the restricted area, the information code of the section behind the restricted area, and the status of the signal corresponding to the corresponding section to CTC (Centralized Traffic Control System), so that CTC can perform train scheduling based on the above information, thereby improving the rationality of train scheduling, thereby improving train operation efficiency, and ensuring the safety of on-site personnel.

[0078] A protection method provided in an embodiment of the present application may further include:

[0079] When it is determined that the restricted area needs to be lifted, tracking and coding are carried out according to the information code of the corresponding section before the restricted area is set, and the information code of each section obtained by tracking and coding is sent to the rails of the corresponding section through the track circuit, so that the on-board equipment of the train can obtain the information code of the current section through the rails of the current section, and control the train operation according to the information code of the current section.

[0080] In the embodiment of the present application, when the train control interlocking integrated system determines that the prohibited area needs to be released, it can track and send codes according to the information code of the corresponding section before the prohibited area is set (the corresponding section is specifically the section included in the prohibited area), that is, it can track and send codes according to the information code of the corresponding section when the prohibited area is not set, and it can re-track and send codes according to the actual occupancy of the corresponding section of the prohibited area. In addition, the train control interlocking integrated system can send the information code of each section obtained by tracking and sending codes to the track circuit, and the track circuit sends the information code of each section to the rails of the corresponding section, so that the on-board equipment of the train can obtain the information code of the section where the train is currently located through the rails of the section where the train is currently located, and control the train operation according to the information code of the section where the train is currently located, so that the train can operate according to the original driving plan.

[0081] The integrated train control and interlocking system lifts the prohibition on restricted areas through the above process, so that the train can run according to the normal driving plan and ensure the normal operation of the train.

[0082] Of course, after lifting the prohibition of the restricted area, the train control and interlocking integrated system can also send the information code of each section obtained by tracking and sending codes to CTC, so that CTC can dispatch trains according to the information code of each section. In addition, after lifting the prohibition of the restricted area, the status of the signal corresponding to each section can be reset according to the information code of each section obtained by tracking and sending codes, so that the signal can correctly display the status of the corresponding section.

[0083] A protection method provided in an embodiment of the present application, for determining a prohibited area to be lifted, may include:

[0084] Acquire the status of the relay corresponding to the section included in the prohibited area in real time, and determine the prohibited passage information of the prohibited area according to the status of the relay corresponding to the section included in the prohibited area;

[0085] If the prohibited passage information of the prohibited area is invalid, it is determined that the prohibited area needs to be lifted.

[0086] In an embodiment of the present application, the drive and extraction system connected to the relays corresponding to the sections included in the prohibited area can collect the status of the relays corresponding to the sections included in the prohibited area in real time, and send the real-time collected status of the relays corresponding to the sections included in the prohibited area to the train control interlocking integrated system in real time, so that the train control interlocking integrated system can promptly and quickly determine whether the prohibited area needs to be lifted.

[0087] Accordingly, the train control interlocking integrated system can obtain the status of the relays corresponding to the sections included in the forbidden area in real time, and determine the prohibited passage information of the forbidden area according to the status of the relays corresponding to the sections included in the forbidden area, and judge whether the prohibited passage information of the forbidden area changes from valid to invalid. If the prohibited passage information of the forbidden area is invalid, it means that the forbidden area does not need to play the prohibited function (that is, the forbidden area allows passage), that is, it is determined that the forbidden area needs to be released, and at this time, the operation of releasing the forbidden area can be performed. If the prohibited passage information of the forbidden area is valid, it means that the forbidden area needs to play the prohibited function, and at this time, the state of the forbidden area is maintained.

[0088] Of course, the train control interlocking integrated system can also obtain the set duration of the prohibited area. When the set duration of the prohibited area exceeds the preset duration, it can be determined that the prohibited area needs to be released. Among them, the preset duration can be set by relevant personnel according to the maintenance duration of the area.

[0089] A protection method provided in an embodiment of the present application, which determines a prohibited area according to prohibited passage information of each section, may include:

[0090] When the prohibited passage information of a section is valid, the section with the prohibited passage information being valid is determined as a prohibited passage area;

[0091] When the prohibited passage information of multiple consecutive sections is valid, the multiple consecutive sections where the prohibited passage information is valid are determined as prohibited passage areas;

[0092] When the no-travel information of multiple non-continuous sections is valid, each section where the no-travel information is valid and non-continuous is determined as a no-travel area; wherein, if the no-travel information is valid and there are at least two continuous sections where the no-travel information is valid among the multiple non-continuous sections, the continuous sections where the no-travel information is valid are determined as a no-travel area.

[0093] In the embodiment of the present application, the specific method for the integrated train control and interlocking system to determine the prohibited area according to the prohibited passage information of each section may be:

[0094] (1) When the prohibited passage information of a section is valid, the section with the prohibited passage information is determined as a prohibited passage area;

[0095] (2) When the prohibited passage information of multiple consecutive sections is valid, the multiple consecutive sections with the prohibited passage information are determined as prohibited areas; for example, when the prohibited passage information of three consecutive sections, section 3, section 4, and section 5, is valid, the three consecutive sections, section 3, section 4, and section 5, can be determined as prohibited areas.

[0096] (3) When the prohibited passage information of multiple non-continuous sections is valid, each section where the prohibited communication information is valid and non-continuous is determined as a prohibited passage area, wherein, when the prohibited communication information of at least two consecutive sections is valid among the multiple sections where the prohibited passage information is valid and non-continuous, the consecutive sections where the prohibited passage information is valid are determined as a prohibited passage area. For example, when the prohibited passage information of three non-continuous sections, sections 1, 3, and 9, is valid, the three non-continuous sections, sections 1, 3, and 9, are respectively determined as a prohibited passage area; when the prohibited passage information of three sections, sections 1, 8, and 9, is valid, since sections 8 and 9 are continuous, the two consecutive sections, sections 8 and 9, are determined as a prohibited passage area, and section 1 is determined as a prohibited passage area alone.

[0097] The above method can realize accurate determination of the prohibited area and reduce the coverage of the prohibited area as much as possible, so as to reduce the impact range of protection as much as possible.

[0098] A protection method provided in an embodiment of the present application may further include, after determining a prohibited area according to prohibited passage information of each section:

[0099] Set the protection status corresponding to the prohibited area to prohibited, display the protection status of the prohibited area, and send the protection status of the prohibited area to CTC.

[0100] In an embodiment of the present application, after determining the prohibited area based on the prohibited passage information of each section, the protection status corresponding to the prohibited area can be set to prohibited passage, and the protection status of the prohibited area can be displayed (specifically, the protection status of the prohibited area can be displayed on the operation display of the integrated train control and interlocking system), and the protection status of the prohibited area can also be sent to CTC, so that relevant personnel can intuitively and quickly determine the prohibited area through the protection status of the prohibited area, and enable CTC to perform train scheduling according to the protection status of the prohibited area.

[0101] The scenarios in which the train is located can be divided into the scenarios of leaving the storage line / depot, the mainline maintenance scenario, the train entering the depot for maintenance, the temporary parking scenario, etc. The train control and interlocking integrated system can perform the following prohibited area settings and removal processing for the aforementioned scenarios:

[0102] (1) Leaving the parking line / garage scene

[0103] When the integrated train control interlocking system determines that the prohibited passage information of the prohibited area is valid according to the relay status transmitted by the driving and mining system, it sends the H code to control the train not to move, and reports the protection status of the prohibited area to CTC; when the prohibited passage information of the prohibited area is determined to be invalid according to the relay status transmitted by the driving and mining system (that is, the prohibited area is allowed to pass), according to the normal driving plan, the trains on the storage line are subjected to train-level static and dynamic tests, and the trains are allowed to automatically leave the storage line / depot.

[0104] (2) Mainline maintenance scenario

[0105] When routine maintenance is required in the train mainline area, in order to ensure the safety of maintenance personnel, according to the start time of the maintenance plan, the integrated train control and interlocking system receives the corresponding section information and relay status transmitted by the drive and mining system, sets the area corresponding to the maintenance as a prohibited area, sends the corresponding area as an H code, and sets the driving permission of the rear train to the starting point of the prohibited area. Trains that have entered the prohibited area output emergency braking, trains that have stopped are prohibited from starting, and trains behind are prohibited from entering the prohibited area. When the maintenance is completed, the integrated train control and interlocking system determines that the prohibited passage information of the prohibited area is invalid (that is, the prohibited area allows passage) according to the relay status transmitted by the drive and mining system. At this time, according to the actual occupancy of the prohibited area, the code is re-tracked and the prohibition of the prohibited area is lifted. The status of the relevant area is sent to CTC.

[0106] (3) Train depot maintenance scenario

[0107] The train has completed its operation plan and needs to be put into the depot for maintenance. After the train returns to the depot and stops, the traction is cut off, and the integrated train control interlocking system determines that the prohibited passage information of one or some sections is valid according to the relay status transmitted by the drive and mining system, sets the area corresponding to the garage as a prohibited area, and sends the H code. After the vehicle stopped in the depot receives the H code, it applies the brakes to ensure that the train does not move. When the maintenance is completed, the integrated train control interlocking system determines that the prohibited passage information of the prohibited area is invalid according to the relay status transmitted by the drive and mining system, and then lifts the prohibition of the prohibited area. The status of the relevant area is sent to CTC.

[0108] (4) Temporary parking scene

[0109] When a sudden fault or other abnormal situation occurs in a certain area on the line, the train in this area needs to be stopped urgently and the rear train is prohibited from entering the area. At this time, the integrated train control interlocking system can determine that the prohibited passage information of the prohibited area is valid according to the relay status transmitted by the drive and mining system, set the H code for the prohibited area, and set the driving permission of the rear train to the starting point of the prohibited area. When the regional fault or other abnormality is restored, the regional prohibition is lifted according to the relay status transmitted by the drive and mining system. The relevant regional status is sent to CTC.
