Description

Technical Field

[0001] The present 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 Art

[0002] The Centralized Traffic Control (CTC) system is a remote control and telesignaling system used by train dispatchers at a dispatching center to centrally control and monitor signaling equipment at stations within their jurisdiction, and to coordinate and direct train operations. The CTC system typically interfaces with systems such as the TDMS (Traffic Data Management System) and construction management systems to implement equipment locking and unlocking functions based on construction plans.

[0003] Railway train approach warning systems currently typically use high-precision Beidou satellite positioning, electronic maps, construction plans, station approach information, locomotive position information, etc. to provide on-site construction personnel with early warning of incoming trains. This railway train approach warning system provides certain train approach warning and protection functions for on-site construction personnel.

[0004] However, CTC systems typically implement access control by setting equipment blocking and unlocking conditions based on fixed construction plans from systems like TDMS and construction management systems. However, this blocking approach cannot dynamically set blocked equipment and areas based on the actual scope and content of on-site construction work. Furthermore, current railway train approach warning systems are typically non-safety auxiliary warning and protection systems, unable to accurately control locomotive stops. They primarily serve as early warnings, sending only warnings to on-site construction personnel when a train approaches, but unable to prevent locomotives from entering the construction area, thereby preventing collisions.

[0035] The following is a further detailed description of a railway train approach warning protection system and method based on a CTC system proposed by the present invention, in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will become clearer. It should be noted that the drawings are in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the drawings. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the implementation conditions of the present invention. Therefore, they have no technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0036] like Figure 1 As shown, this embodiment provides a railway train approach warning and protection system based on the CTC system, including: a train approach warning system 20, which is used to obtain the construction operation electronic fence in real time and extract equipment information from the construction operation electronic fence; a CTC system 10, which is communicated with the train approach warning system 20 and is used to generate a blocking instruction based on its own construction plan information or the equipment information sent by the train approach warning system 20; a computer interlocking system 30, which is communicated with the CTC system 10 and is used to execute the blocking instruction to realize the blocking of signal equipment and approach control in the construction operation area to prevent locomotives from entering the construction area.

[0037] This embodiment does not require the addition of locomotive-mounted positioning equipment. By using the construction operation electronic fence and the CTC system, that is, integrating the real-time construction operation area of ​​the early warning system and the construction blocking logic and access control function of the CTC system, locomotives are prevented from entering the construction operation area at the source.

[0038] Please continue to refer to Figure 1As shown, the CTC system includes a train operation terminal 101, a CTC server 102 and a CTC interface device 103. The CTC server 102 is in communication with the computer interlocking system 30. The train approach warning system includes an early warning server 202 and terminal equipment.

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

[0040] Please continue to refer to Figure 1 As shown, the terminal device may include a handheld terminal 203 and a monitoring terminal 204, each of which communicates with the early warning server 202. The station liaison officer can bind the construction worker information and handheld terminal 203 information for the construction plan to the monitoring terminal 204. After the construction plan is bound to the construction worker's handheld terminal 203, the early warning server 202 automatically transmits the corresponding construction plan information to the corresponding construction worker's handheld terminal 203, allowing the construction worker to view the construction plan content through the handheld terminal 203. At this time, the construction worker enters the work area within the construction work electronic fence at the construction plan start time. The terminal device, specifically the handheld terminal 203, provides the early warning server 202 with the construction worker's satellite positioning location information and a "prepare to go on the road" command. The CTC system 102 automatically generates a blockade command based on the "prepare to go on the road" command and the construction plan information. The blockade command is transmitted via the CTC server 102 to the computer interlocking system 30, which executes the blockade command to block the signal equipment in the work area and control the access route, preventing locomotives from entering the construction area.

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

[0042] Please continue to refer to Figure 1 As shown, the train approach warning system 20 further includes a warning interface machine 201 for communicating with the CTC interface machine 103 in the CTC system 10 .

[0043] Please continue to refer to Figure 1 As shown, this embodiment further includes a bidirectional network gatekeeper 31, through which the warning interface machine 201 communicates with the CTC interface machine 103. The bidirectional network gatekeeper 31 implements network security isolation between the train approach warning system 20 and the CTC system 10.

[0044] Please continue to refer to Figure 1 As shown, when on-site construction personnel need to deal with on-site emergency failures and other operations without a fixed construction plan, that is, 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 operation area. The monitoring terminal 204 generates a temporary construction plan based on the temporary construction request, and generates a construction operation electronic fence on the station vectorized electronic map of the monitoring terminal based on the temporary construction plan and the actual on-site operation area; and is also used to feedback the temporary construction plan and the construction operation electronic fence to the early warning server 202.

[0045] After the early warning server 202 receives the temporary construction plan and the construction operation electronic fence issued by the monitoring terminal 204, it extracts the equipment information contained in the construction operation electronic fence after processing (the equipment information includes equipment on the line such as signals, switches and tracks), and sends the extracted equipment information to the CTC server 102 of the CTC system 10 through the early warning interface machine 201 and the CTC interface machine 103. The CTC server 102 generates a blocking instruction, and the computer interlocking system 30 is used to execute the blocking instruction to realize the equipment blocking and access control of the temporary construction operation area to prevent locomotives from entering the construction area.

[0046] Specifically, the CTC server 102 also sends a blocking instruction (the blocking instruction includes information about the equipment to be blocked) to the vehicle service terminal 101, and the vehicle service terminal 101 manually confirms the information about the equipment to be blocked. If the confirmation is passed, the construction operation electronic fence is valid, and the blocking instruction is sent to the computer interlocking system 30; if it is not passed, the early warning server 202 is controlled to send a temporary construction plan creation failure message to the monitoring terminal 204 to interrupt this temporary construction plan.

[0047] Furthermore, the station liaison officer can bind the construction worker information and handheld terminal 203 information of the temporary construction plan on the monitoring terminal 204. After the temporary construction plan is bound to the construction worker's handheld terminal 203, the early warning server 202 is further configured to send the valid construction operation electronic fence and temporary construction plan to the handheld terminal 203. The construction worker can view the temporary construction plan on the handheld terminal 203 and enter the construction area according to the construction operation electronic fence to carry out on-road work. After that, the CTC server 102 sends a blocking instruction to the computer interlocking system 30, which executes the blocking instruction, thereby blocking equipment in the temporary construction area and controlling access to the road, preventing locomotives from entering the construction area.

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

[0049] Specifically, at this time, the on-site construction personnel log in to the handheld terminal 203 with a special work identity. After manually going on the road to the designated work area according to the actual situation, they can use the handheld terminal 203 to manually mark on the station vectorized electronic map to set up temporary construction work electronic fences and temporary construction work tasks. The handheld terminal 203 sends the set construction work electronic fences and temporary construction work tasks to the early warning server 202 via wireless communication.

[0050] After the early warning server 202 receives the temporary construction work task and the construction work electronic fence issued by the handheld terminal 203, it extracts the equipment information contained in the construction work electronic fence after processing (the equipment information includes equipment on the line such as signals, switches and tracks), and sends the extracted equipment information to the CTC server 102 through the early warning interface machine 201 and the CTC interface machine 103. After the CTC server 102 generates a blocking instruction and verifies that the construction work electronic fence is valid through the vehicle service terminal 101, the computer interlocking system 30 is used to execute the blocking instruction to realize the equipment blocking and access control of the temporary construction work area to prevent locomotives from entering the construction area.

[0051] Furthermore, if on-site construction personnel are unable to dynamically set a fixed construction area based on on-site construction requirements, i.e., if they are unable to generate an electronic fence for construction work, the early warning server 202 can dynamically demarcate the electronic fence for construction work based on the satellite positioning information of the construction personnel for the special operation and the set individual activity range (single-person activity radius). The early warning server 202 calculates the equipment information (such as signals, switches, and tracks) contained in the electronic fence based on the automatically generated electronic fence and combined with electronic map data. The early warning server 202 then sends this equipment information and the electronic fence for construction work to the CTC server 102 via the early warning interface 201 and the CTC interface 103. Upon receiving the electronic fence and equipment information, the CTC server 102 prompts a manual confirmation window on the train service terminal 101 to confirm the validity of the electronic fence. After confirmation by the train service personnel at the station, the CTC server 102 generates and sends a blockade command to the computer interlocking system 30. The computer interlocking system 30 executes the blockade command to block the equipment in the temporary construction area and control access to the road, preventing locomotives from entering the construction area.

[0052] In this embodiment, on-site construction workers can manually mark and set up electronic fences for construction operations, or the system can automatically calculate the dynamic activity range of construction workers to dynamically obtain on-site work areas and work contents to generate electronic fences for construction operations. This is more accurate and real-time than traditional fixed construction plans in achieving blockades.

[0053] This embodiment can achieve automatic equipment and area blocking of railway lines through two methods: a fixed construction plan issued by the CTC system and real-time dynamic acquisition of on-site construction areas. At the same time, combined with the manual confirmation method of the train service terminal and the actual start time of on-site construction, it ensures the safety of on-site construction operations and the precise implementation of equipment blocking, thereby improving the safety of on-site construction operations and the efficiency of transportation operations.

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

[0055] Fixed construction plan early warning and protection process and temporary construction plan early warning and protection process.

[0056] The fixed construction plan warning protection process is a protection process in which the train approach warning system 20 receives the construction plan sent by the CTC system 10, and the construction personnel go on the track to work 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 construction plan information to the early warning server and starts equipment pre-lockdown according to the construction plan information.

[0059] Step S2: The early warning server generates a construction area according to the construction plan content in the construction plan information (the construction plan content includes, for example, the name of the work station, the name of the work equipment, and the work time, etc.) combined with its own electronic map data (the electronic map data includes station information, equipment element names, and coordinate information).

[0060] Step S3: The early warning server demarcates an electronic fence based on the generated construction operation area to form a construction operation electronic fence.

[0061] Step S4: The station liaison officer associates the construction plan information with the construction personnel through the monitoring terminal, that is, adds the name of the construction personnel in 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 issues the construction plan information to the construction personnel, and the construction personnel can view their own construction plans on the logged-in handheld terminal.

[0063] Step S6: After receiving the construction plan information through their handheld terminals, when the construction personnel are ready to enter the construction area (within the construction electronic fence) for operation, they manually trigger the prepare-to-go-on-the-road operation command through the handheld terminals. After receiving the prepare-to-go-on-the-road operation command, the early warning server triggers the construction area blockade start command and forwards it to the CTC system. After receiving the construction 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 construction area access blockade and prevent locomotives from entering the construction area.

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

[0065] like Figure 2 As shown in FIG, when the warning server does not receive the construction plan information sent by the CTC system and the on-site construction personnel receive a temporary construction task (such as emergency handling of on-site equipment failure), they execute the temporary construction plan warning protection process, including:

[0066] Step S2.1: Is there a station liaison officer for the current temporary construction task? If yes, proceed to step S2.2; if not, proceed to step S2.4;

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

[0068] Specifically, a temporary construction plan is generated by the monitoring terminal, and the construction operation electronic fence is generated on the station vectorized electronic map of the monitoring terminal according to the temporary construction plan and combined with the actual operation area on site, and fed back to the early warning server.

[0069] Step S2.3: The on-site liaison associates the temporary construction plan (and the construction operation electronic fence) with the construction personnel and the handheld terminal. The construction personnel log in to the handheld terminal as normal. Then proceed to step S2.6.

[0070] Step S2.6: The monitoring terminal sends the generated construction operation electronic fence to the CTC system via the early warning server. The CTC system prompts a window to manually confirm whether the construction operation electronic fence is valid. If not, the system returns to step S2.1; if valid, the system proceeds to step S2.7.

[0071] Specifically, after receiving the equipment information (also known as line equipment information) contained within the construction electronic fence from the early warning system, the CTC system generates construction blockade equipment information based on the equipment information within the construction electronic fence. A pop-up window appears on the train terminal prompting station train personnel to confirm the construction blockade equipment information. If the train personnel do not confirm or select "Confirm" within the specified manual confirmation timeout, the CTC system initiates the equipment blockade and sends an approach blockade instruction to the computer interlocking system, prohibiting access to the blocked equipment. The CTC system then feeds back the result of the manual "Confirm" selection to the early warning server.

[0072] If the user manually selects "Cancel" within the timeout period, the CTC system will not initiate the blockade of related equipment and will feed back the result of the manual selection of "Cancel" to the early warning server.

[0073] That is, when the construction operation electronic fence 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. The construction personnel check the handheld terminal to enter the construction operation electronic fence and start working on the road.

[0075] Specifically, when the construction operation electronic fence is valid, the warning server is controlled to send the construction operation electronic fence to the handheld terminal and the monitoring terminal in the train approach warning system;

[0076] The handheld terminal feeds back a preparation-for-road-operation command and construction worker satellite positioning information to the warning server;

[0077] The early warning server combines the electronic map data and the satellite positioning information of the construction personnel to display the current station equipment status and the construction personnel position status in real time on the station vectorized electronic map.

[0078] Step S2.8: After the construction workers start working on the road, the construction work start instruction in the early warning server is triggered and sent to the CTC system. The CTC system starts the route blockade and performs early warning protection.

[0079] Specifically, the early warning server extracts equipment information from the effective construction electronic fence and sends it to the CTC system; and sends a construction start instruction to the CTC system. After receiving the construction start instruction, the CTC system generates a blocking instruction based on the equipment information; and uses a computer interlocking system to execute the blocking instruction to achieve signal equipment blocking and access control in the construction area.

[0080] Step S2.4: The construction worker logs into the handheld terminal with a special identity and proceeds to step S2.5.

[0081] Step S2.5: The early warning server allows construction workers to use the handheld terminal to mark and set up the construction operation electronic fence in the work area based on the special identity authority of the handheld terminal. If the construction workers do not manually mark and set up the construction operation electronic fence, the early warning server will automatically define the construction workers' construction operation area and generate the construction operation electronic fence based on the construction workers' position and activity range on the track line (the activity radius can be configured, generally the default is 3 meters), and then enter step S2.6.

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