Description

Technical Field

[0001] This invention relates to the field of early warning and protection technology, and in particular to a railway train approach early warning and protection system and method based on a CTC system. Background Technology

[0002] The Centralized Traffic Control (CTC) system refers to a remote control and signaling system in which train dispatchers centrally control and monitor the signaling equipment of each station within their jurisdiction at the dispatch center, and uniformly dispatch and command train operations. The CTC system can usually achieve equipment locking and unlocking functions based on construction plans through interfaces with systems such as TDMS (Train Data Management System) and construction management.

[0003] Railway train approach warning systems typically use high-precision BeiDou satellite positioning, electronic maps, construction plans, station route information, and locomotive location information to provide on-site construction personnel with early warnings of approaching trains. This system provides a certain level of protection for on-site construction personnel against train approach warnings.

[0004] However, CTC systems typically set equipment blocking and unlocking conditions based on fixed construction plans established by TDMS and construction management systems to control route access. This blocking method cannot dynamically set blocking equipment and areas based on the actual work scope and content on site. Furthermore, current railway train approach warning systems are usually non-safety auxiliary warning and protection systems, unable to accurately control locomotive stopping. They are mainly used as early warning alerts; when a train approaches, they only send a warning to on-site construction personnel, failing to prevent the locomotive from entering the construction area and thus preventing collisions. Summary of the Invention

[0005] The purpose of this invention is to provide a railway train approach warning and protection system and method based on a CTC system, which controls locomotives to prevent them from entering the on-site construction area, thereby preventing collision accidents.

[0012] The early warning server is also used to generate a construction operation area and delineate the construction operation electronic fence based on the construction plan content in the construction plan information and its own electronic map data.

[0013] And based on the satellite positioning information of the construction personnel, the current status of the station equipment and the location status of the construction personnel are displayed in real time on the station vectorized electronic map generated based on the electronic map data;

[0014] The early warning server is also used to feed back the preparation for track operation command to the CTC system, and the CTC system generates the blockade command based on the preparation for track operation command.

[0016] Optionally, the train approach warning system further includes: a warning interface unit for communicating with the CTC interface unit in the CTC system.

[0017] Optionally, it also includes: a two-way network gateway, wherein the early warning interface unit is communicatively connected to the CTC interface unit through the two-way network gateway.

[0018] Optionally, the equipment information includes at least signals, switches, and tracks.

[0019] On the other hand, the present invention also provides a railway train approach warning and protection method based on a CTC system, including: a fixed construction plan warning and protection process; the fixed construction plan warning and protection process includes: obtaining construction plan information from the CTC system through a train approach warning system, and automatically generating an electronic fence for construction operations on a station vectorized electronic map according to the construction plan content in the construction plan information; generating a blocking command through the CTC system according to the construction plan information;

[0020] The blocking command is executed by a computer interlocking system to block signal equipment and control access routes in the construction area.

[0030] 2. This invention can dynamically obtain the on-site work area and work content by having on-site construction personnel manually mark points to set up electronic fences or by having the system automatically calculate the dynamic activity range of construction personnel, which is more accurate and real-time than the traditional fixed construction plan for sealing off the site.

[0035] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the railway train approach warning and protection system and method based on a CTC system proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the embodiments of this invention. Please refer to the accompanying drawings to make the objectives, features, and advantages of this invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this invention, should still fall within the scope of the technical content disclosed in this invention.

[0036] like Figure 1 As shown, this embodiment provides a railway train approach warning and protection system based on a CTC system, including: a train approach warning system 20, used to acquire construction operation electronic fences in real time and extract equipment information from the construction operation electronic fences; a CTC system 10, which is communicatively connected to the train approach warning system 20, used to generate a blocking command based on its own construction plan information or the equipment information sent by the train approach warning system 20; and a computer interlocking system 30, which is communicatively connected to the CTC system 10, used to execute the blocking command to block signal equipment and control routes in the construction operation area, preventing locomotives from entering the construction area.

[0037] This embodiment does not require additional locomotive onboard positioning equipment. By using the construction operation electronic fence and CTC system, which integrates the real-time construction operation area of ​​the early warning system with the construction blockade logic and route control function of the CTC system, locomotives are prevented from entering the construction operation area from the source.

[0038] Please continue to refer to this. Figure 1As shown, the CTC system includes a train operation terminal 101, a CTC server 102, and a CTC interface unit 103; wherein, the CTC server 102 is communicatively connected to the computer interlocking system 30. The train approach warning system includes: a warning server 202 and terminal equipment.

[0039] When the CTC system 10 issues a fixed construction plan, the early warning server 202 is used to receive the construction plan information sent by the CTC system 10; and to generate a construction operation area based on the construction plan content in the construction plan information and its own electronic map data, and to delineate the construction operation electronic fence based on the construction operation area.

[0040] Please continue to refer to this. Figure 1 As shown, the terminal equipment may include a handheld terminal 203 and a monitoring terminal 204 that communicate with the early warning server 202 respectively. The station liaison officer can bind the construction personnel information and handheld terminal 203 information of the construction plan to the monitoring terminal 204. After the construction plan is bound to the handheld terminal 203 of the construction personnel, the early warning server 202 automatically sends the corresponding construction plan information to the handheld terminal 203 of the corresponding construction personnel. The construction personnel can view the construction plan content through the handheld terminal 203. At this time, the construction personnel enter the work area within the electronic fence of the construction operation according to the start time of the construction plan. Specifically, the handheld terminal 203 feeds back the satellite positioning information of the construction personnel and the order to prepare for track work to the early warning server 202. The CTC system 102 automatically generates a blocking instruction based on the order to prepare for track work and the construction plan information. The blocking instruction is sent to the computer interlocking system 30 through the CTC server 102. The computer interlocking system 30 executes the blocking instruction to block the signal equipment in the work area and control the route, preventing locomotives from entering the construction area.

[0041] In addition, the early warning server 202 is also used to display the current status of station equipment and the location status of construction personnel on the station vectorized electronic map generated based on the electronic map data in real time, based on the satellite positioning information of construction personnel on site fed back by the handheld terminal 203.

[0042] Please continue to refer to this. Figure 1 As shown, the train approach warning system 20 also includes a warning interface unit 201, which is used to communicate with the CTC interface unit 103 in the CTC system 10.

[0043] Please continue to refer to this. Figure 1 As shown, this embodiment also includes a two-way network gateway 31, through which the early warning interface unit 201 is communicatively connected to the CTC interface unit 103. The two-way network gateway 31 enables network security isolation between the train approach warning system 20 and the CTC system 10.

[0044] Please continue to refer to this. Figure 1 As shown, when on-site construction personnel need to handle on-site emergency faults or other work without a fixed construction plan, i.e., when there is a temporary construction plan, the station liaison officer can send a temporary construction request to the monitoring terminal 204 based on the actual on-site work area. The monitoring terminal 204 generates a temporary construction plan based on the temporary construction request, and generates an electronic fence for construction work on the station vectorized electronic map of the monitoring terminal based on the temporary construction plan and the actual on-site work area; and is also used to feed back the temporary construction plan and the electronic fence for construction work to the early warning server 202.

[0045] After receiving the temporary construction plan and construction operation electronic fence issued by the monitoring terminal 204, the early warning server 202 processes and extracts the equipment information contained in the construction operation electronic fence (the equipment information includes equipment on the line such as signals, switches and tracks). The extracted equipment information is sent to the CTC server 102 of the CTC system 10 through the early warning interface 201 and the CTC interface 103. The CTC server 102 generates a blockade command, and the computer interlocking system 30 executes the blockade command to realize the equipment blockade and route control of the temporary construction operation area, preventing locomotives from entering the construction area.

[0046] Specifically, the CTC server 102 also sends a blocking command (which includes information about the equipment to be blocked) to the vehicle terminal 101. The vehicle terminal 101 manually confirms the information about the equipment to be blocked. If the confirmation is successful, the electronic fence for the construction operation is effective, and the blocking command is sent to the computer interlocking system 30. If the confirmation fails, the early warning server 202 is controlled to send a temporary construction plan creation failure message to the monitoring terminal 204, thus interrupting the temporary construction plan.

[0047] Furthermore, the station liaison officer can bind the construction personnel information and handheld terminal 203 information of the temporary construction plan to the monitoring terminal 204. After the temporary construction plan is bound to the construction personnel's handheld terminal 203, the early warning server 202 is also used to send the effective construction operation electronic fence and the temporary construction plan to the handheld terminal 203. The construction personnel can view the temporary construction plan on the handheld terminal 203 and enter the construction operation area according to the construction operation electronic fence to carry out track work. After that, the CTC server 102 sends a blocking command to the computer interlocking system 30. The computer interlocking system 30 executes the blocking command to realize the equipment blocking and route control of the temporary construction operation area, preventing locomotives from entering the construction area.

[0048] Please continue to refer to this. Figure 1As shown, when there is no fixed construction plan and no station liaison, and on-site construction personnel need to go to the track to handle work without a fixed construction plan, the handheld terminal 203 is used to generate the electronic fence for the construction work according to the manual trigger command.

[0049] Specifically, at this time, the on-site construction personnel log in on the handheld terminal 203 as special operation personnel. They can manually go to the designated work area according to the actual situation and then manually mark points on the station's vectorized electronic map using the handheld terminal 203 to set up temporary construction operation electronic fences and temporary construction operation tasks. The handheld terminal 203 sends the set construction operation electronic fences and temporary construction operation tasks to the early warning server 202 via wireless communication.

[0050] After receiving the temporary construction task and construction operation electronic fence issued by the handheld terminal 203, the early warning server 202 processes and extracts the equipment information contained in the construction operation electronic fence (the equipment information includes equipment on the line such as signals, switches and tracks). The extracted equipment information is sent to the CTC server 102 through the early warning interface 201 and the CTC interface 103. The CTC server 102 generates a blocking command, and after the train terminal 101 verifies the validity of the construction operation electronic fence, the computer interlocking system 30 executes the blocking command to realize the equipment blocking and route control of the temporary construction operation area, preventing locomotives from entering the construction area.

[0051] In addition, if on-site construction personnel cannot dynamically set a fixed construction area based on on-site construction needs, i.e., they cannot generate an electronic fence for construction operations, the early warning server 202 can dynamically delineate the electronic fence for construction operations based on the satellite positioning information of the special operation personnel and the set single-person activity range (single-person activity radius). Based on the automatically generated electronic fence for construction operations and combined with electronic map data, the early warning server 202 calculates the equipment information (such as signals, switches, tracks, etc.) included in the electronic fence for construction operations. Then, it sends the equipment information and the electronic fence for construction operations to the CTC server 102 through the early warning interface 201 and the CTC interface 103. After receiving the electronic fence for construction operations and the equipment information, the CTC server 102 prompts for manual confirmation of the validity of the electronic fence for construction operations through a pop-up window on the train operation terminal 101. After confirmation by the station train operation personnel, the CTC server 102 generates and sends a blocking command to the computer interlocking system 30. The computer interlocking system 30 executes the blocking command to achieve equipment blocking and route control in the temporary construction operation area, preventing locomotives from entering the construction area.

[0052] This embodiment can dynamically obtain the on-site work area and work content to generate an electronic fence by having on-site construction personnel manually mark points or by having the system automatically calculate the dynamic activity range of construction personnel. This is more accurate and real-time than the traditional fixed construction plan for achieving closure.

[0053] This embodiment can achieve automatic equipment and area blockade of railway lines through two methods: fixed construction plans issued by the CTC system and real-time dynamic acquisition of on-site construction operation areas. At the same time, it combines manual confirmation by train operation terminals and the actual start time of on-site construction to ensure the safety of on-site construction operations and the precise implementation of equipment blockade, thereby improving the safety of on-site construction operations and the efficiency of transportation operations.

[0054] This embodiment also provides a railway train proximity warning and protection method based on a CTC system, including:

[0055] The early warning and protection process for fixed construction plans and the early warning and protection process for temporary construction plans.

[0056] The fixed construction plan early warning and protection process is the process by which the train approach warning system 20 receives the construction plan sent by the CTC system 10, and the construction personnel carry out the protection work on the track according to the construction plan.

[0057] Among them, such as Figure 3 As shown, the fixed construction plan early warning and protection process includes:

[0058] Step S1: The CTC system sends the construction plan information to the early warning server and initiates equipment pre-lockdown based on the construction plan information.

[0059] Step S2: The early warning server generates the construction operation area based on the construction plan content in the construction plan information (such as the name of the work station, the name of the work equipment, and the work time), combined with its own electronic map data (which includes station information, equipment element names, and coordinate information).

[0060] Step S3: The early warning server delineates an electronic fence based on the generated construction operation area, thus forming an electronic fence for the construction operation.

[0061] Step S4: The station liaison officer associates the construction plan information with the construction personnel through the monitoring terminal. That is, the construction personnel's name is added to the personnel option of the construction plan information, and then the construction personnel log in to their respective handheld terminals.

[0062] Step S5: The station liaison officer distributes the construction plan information to the construction workers, who can then view their construction plan on their logged-in handheld terminals.

[0063] Step S6: When construction personnel receive the construction plan information through their handheld terminals and prepare to enter the construction work area (within the electronic fence of the construction work area), they manually trigger the preparation to enter the work area command through their handheld terminals. After receiving the preparation to enter the work area command, the early warning server triggers the construction work area blockade start command and forwards it to the CTC system. After receiving the construction work area blockade start command, the CTC system generates a blockade command according to the construction plan information and executes the blockade command through the computer interlocking system to control the road blockade and control of the construction area to prevent locomotives from entering the construction area.

[0064] In this embodiment, the fixed construction plan early warning and protection process further includes: construction personnel feeding back their satellite positioning information to the early warning server through the handheld terminal; and the early warning server combining the electronic map data and the construction personnel's satellite positioning information to display the current station equipment status and construction personnel location status in real time on the station's vectorized electronic map.

[0065] like Figure 2 As shown, when the early warning server does not receive construction plan information from the CTC system, and on-site construction personnel receive temporary construction tasks (such as emergency handling of on-site equipment failures), the temporary construction plan early warning protection process is executed, including:

[0066] Step S2.1: Is there a station liaison officer for the current temporary construction task? If so, proceed to step S2.2; otherwise, proceed to step S2.4.

[0067] Step S2.2: The station liaison officer creates a temporary construction plan and an electronic fence for construction operations on the station monitoring terminal;

[0068] Specifically, a temporary construction plan is generated through the monitoring terminal, and based on the temporary construction plan and the actual work area on site, an electronic fence for the construction operation is generated on the station vectorized electronic map of the monitoring terminal and fed back to the early warning server.

[0069] Step S2.3: The on-site liaison officer associates the temporary construction plan (and the electronic fence for construction operations) with the construction personnel and their handheld terminals. The construction personnel log in to their handheld terminals with normal identities and proceed to step S2.6.

[0070] Step S2.6: The monitoring terminal sends the electronic fence for construction operations it generates to the CTC system through the early warning server. The CTC system pops up a window for manual confirmation of whether the electronic fence for construction operations is valid. If it is invalid, return to step S2.1; if it is valid, proceed to step S2.7.

[0071] Specifically, after receiving the equipment information (also known as line equipment information) contained in the construction operation electronic fence sent by the early warning system, the CTC system generates construction closure equipment information based on the equipment information within the construction operation electronic fence. This information is then displayed as a pop-up notification on the train operation terminal, prompting station staff to confirm the construction closure equipment information. If the staff does not confirm or select "confirm" within the specified manual confirmation timeout period, the CTC system initiates the equipment closure and sends a route closure command to the computer interlocking system, prohibiting any route to the closed equipment. The CTC system also feeds back the result of the manual "confirmation" selection to the early warning server.

[0072] If the user manually selects "cancel" within the timeout period, the CTC system will not initiate the relevant device blocking and will send the result of the manual "cancel" selection back to the early warning server.

[0073] When the electronic fence for the construction operation is invalid, the early warning server is controlled to send a temporary construction plan creation failure message to the handheld terminal and the monitoring terminal, thereby interrupting the temporary construction plan.

[0074] Step S2.7: The monitoring terminal sends the construction operation electronic fence to the handheld terminal, and the construction personnel enter the construction operation electronic fence to carry out the work on the track by viewing the handheld terminal.

[0075] Specifically, when the construction operation electronic fence is effective, the control system sends the construction operation electronic fence to the handheld terminal and monitoring terminal in the train approach warning system.

[0076] The handheld terminal sends a command to prepare for track work and satellite positioning information of the construction personnel to the early warning server.

[0077] The early warning server, in conjunction with the electronic map data and the satellite positioning information of the construction personnel, displays the current status of the station's equipment and the location of the construction personnel on the station's vectorized electronic map in real time.

[0078] Step S2.8: After the construction personnel start working on the track, the construction operation start command in the early warning server is triggered and sent to the CTC system. The CTC system then initiates route blocking and performs early warning protection.

[0079] Specifically, the early warning server extracts and sends equipment information from the valid electronic fence of the construction operation to the CTC system; and sends a construction operation start command to the CTC system. After receiving the construction operation start command, the CTC system generates a blocking command based on the equipment information; and a computer interlocking system is used to execute the blocking command to realize the blocking of signal equipment and route control in the construction operation area.

[0080] Step S2.4: Construction personnel log in to the handheld terminal with a special identity and proceed to step S2.5.

[0081] Step S2.5: The early warning server, based on the special identity permissions of the handheld terminal, allows construction personnel to use the handheld terminal to mark points and set up electronic fences for construction work in the work area. If the construction personnel do not manually mark points and set up electronic fences for construction work, the early warning server will automatically delineate the construction work area of ​​the construction personnel and generate electronic fences based on the location and activity range of the construction personnel on the track line (the activity radius can be configured, and it can generally be 3 meters by default). Then proceed to step S2.6.

[0082] In summary, this embodiment can achieve automatic equipment and area blockade of railway lines through two methods: construction plan issued by the CTC system and real-time dynamic acquisition of on-site construction operation areas. At the same time, it combines the manual confirmation method of CTC station with the actual start time of on-site construction to ensure the safety of on-site construction operations and the precise implementation of equipment blockade, thereby improving the safety of on-site construction operations and the efficiency of transportation operations.
