Description

Technical Field

[0001] The present invention relates to a train signal control system, and more particularly to a protection device, method, equipment and medium for abnormal opening of platform doors in a FAM (Fully Automatic Driving Mode) system. Background Art

[0002] The platform door is installed on the side edge of the subway platform near the track, and is a device that separates the platform area from the track area. When the train arrives, the electric doors on the glass curtain wall are opened for passengers to get on and off the train. The main purpose of setting up the platform door is to prevent people from falling onto the track and having accidents, reduce the operating energy consumption of the station air conditioning and ventilation system, reduce the impact of train operation noise and piston wind on the station at the same time, provide a safe and comfortable waiting environment for passengers, avoid delaying operations due to platform accidents, improve the service level of rail transit, and create necessary conditions for the rail transit system to achieve full automatic driverless operation.

[0003] For fully automatic driverless lines, the signal system automatically controls the opening and closing of the platform doors according to corresponding conditions. During the process of entering and leaving the station, the train will continuously detect the closed state of the platform doors. Once the on-vehicle control system detects that the platform doors are opened, it will immediately control the train to brake emergently. However, when the train is far from the platform before entering the station, if the platform doors are abnormally opened and then closed instantaneously, the train will not be able to judge when it enters the station. If there are people or foreign objects falling into the platform track area during the abnormal opening and closing of the platform, casualties will surely occur during the train's approach to the station, bringing great safety risks to passengers and train operations. Even if the station staff can timely discover that there are people or foreign objects falling into the platform track area due to abnormal opening of the platform doors, it is very difficult to timely control the approaching train to stop.

[0004] Therefore, how to make the platform door system continuously protected after abnormal opening, improve the system response efficiency, improve the train operation safety, and reduce the labor intensity of platform staff has become an urgent problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a protection device, method, equipment and medium for abnormal opening of platform doors, which improves the automatic linkage level, response efficiency and train operation safety of the signal and platform door systems, and reduces the labor intensity of platform staff.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] According to the first aspect of the present invention, a protection device for abnormal opening of platform screen doors is provided. The device is used in the FAM system. The protection device includes a zone controller ZC, a vehicle controller CC, an interlocking system, a platform screen door system, and an ATS system. The interlocking system is communicatively connected to the zone controller ZC, the vehicle controller CC, the platform screen door system, and the ATS system respectively. The zone controller ZC is communicatively connected to the vehicle controller CC and the ATS system respectively;

[0008] The zone controller ZC is built-in with a safety protection software module. When the zone controller ZC receives the loss of the closing and locking information of the platform screen doors at a certain platform and does not receive the door enabling information calculated by the vehicle controller CC and / or the vehicle door opening instruction, the safety protection software module immediately establishes a protection area for the platform track area of this platform.

[0009] As a preferred technical solution, the interlocking system collects the closing and locking information of the platform screen doors and the unlocking of the interlock through a relay interface and sends it to the zone controller ZC.

[0010] As a preferred technical solution, after the train enters the station and stops stably and accurately, the vehicle controller CC calculates the door opening enablement and the vehicle door or platform screen door opening instruction. When the stop time ends, the vehicle door or platform screen door closing instruction is calculated, and the door opening enablement information is sent to the zone controller ZC.

[0011] As a preferred technical solution, the platform screen door opening and closing commands of the vehicle controller CC are all sent to the interlocking system.

[0012] As a preferred technical solution, after receiving the opening and closing instruction, the interlocking system forwards it to the platform screen door system through a relay interface.

[0013] As a preferred technical solution, the ATS system gives an alarm for abnormal opening of the platform screen doors and displays the safety protection of the platform track area on the central / station dispatching workstation terminal.

[0014] As a preferred technical solution, the ATS system provides an operation to manually cancel the protection area on the central / station dispatching workstation. After the protection area for the platform track area is established, the staff can confirm that there is no risk and then cancel the protection area.

[0015] As a preferred technical solution, the ATS system provides operations to manually establish and cancel the protection area for the platform track area on the central / station dispatching workstation terminal.

[0016] According to the second aspect of the present invention, a protection method using the protection device for abnormal opening of the platform screen doors is provided, including the following steps:

[0017] Step S1: After the train stops at the station, after the on-vehicle controller CC detects that the train has stopped stably and accurately, it calculates the door opening enablement and the door opening command for the train doors or platform screen doors, and sends the door opening enablement information to the zone controller ZC and sends the platform screen door opening command to the interlocking system;

[0018] Step S2: After receiving the door opening command, the interlocking system forwards it to the platform screen door system through the relay interface;

[0019] Step S3: After receiving the door opening command, the platform screen door system executes the door opening. After the platform screen door system controls the platform screen door closing and locking interface relay of the interlocking system to drop, the interlocking system collects that the platform screen door closing and locking relay has dropped, determines that the platform screen door has been opened and forwards it to the zone controller ZC;

[0020] Step S4: When the stop time ends, the on-vehicle controller CC calculates the door / platform screen door closing command and sends the platform screen door closing command to the interlocking system;

[0021] Step S5: After receiving the door closing command, the interlocking system forwards it to the platform screen door system through the relay interface;

[0022] Step S6: After receiving the door closing command, the platform screen door system executes the door closing. After the platform screen door is closed and locked, it controls the platform screen door closing and locking interface relay of the interlocking system to pick up. The interlocking system collects that the platform screen door closing and locking relay has picked up, determines that the platform screen door has been closed and forwards it to the zone controller ZC;

[0023] Step S7: After the on-vehicle controller CC determines that the departure conditions are met, it automatically controls the train to leave the station;

[0024] Step S8: When the train does not enter the station or does not stop accurately at the station, the platform screen door causes the platform screen door closing and locking interface relay of the interlocking system to drop. The interlocking system collects that the platform screen door closing and locking relay has dropped, determines that the platform screen door has been opened and forwards it to the zone controller ZC. If the zone controller ZC does not receive the door opening enablement information sent by the on-vehicle controller CC, it determines that the platform screen door has been abnormally opened, and establishes a safety protection area for the platform track area. The zone controller ZC determines that other trains have entered or are approaching the protection sub-area, and will send a trigger for emergency braking to prevent normal trains from entering the platform track area as much as possible and prevent safety accidents from occurring.

[0025] As a preferred technical solution, the abnormal opening of the platform screen door in step S8 also includes the situation where the platform screen door recovers instantly when it is opened.

[0026] As a preferred technical solution, the method further includes:

[0027] Step S9: After the safety protection area for the platform track area is established, an alarm for abnormal opening of the platform screen door and a safety protection display for the platform track area will be given at the central / station ATS dispatching terminal.

[0028] As a preferred technical solution, the method further includes:

[0029] Step S10: After ensuring safety, the staff manually operate to cancel the safety protection area of the platform track at the central / station ATS dispatching terminal.

[0030] As a preferred technical solution, the staff ensure safety by confirming through a camera or on-site that there are no personnel or foreign objects invading the track area.

[0031] As a preferred technical solution, the method further includes:

[0032] Step S11: When the staff find any abnormality in the platform track area, they operate on the central / station ATS dispatching workstation terminal to establish and cancel the safety protection area of the platform track.

[0033] According to the third aspect of the present invention, there is provided an electronic device, including a memory and a processor, wherein a computer program is stored on the memory, and when the processor executes the program, the method as described above is implemented.

[0034] According to the fourth aspect of the present invention, there is provided a computer-readable storage medium, on which a computer program is stored, and when the program is executed by a processor, the method as described above is implemented.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] 1. When the signal system detects an abnormal opening of the platform door in the present invention, the ZC system automatically establishes a safety protection area for the platform track without manual operation, improving the system safety and reducing the labor intensity of the staff.

[0037] 2. When the signal system detects an abnormal opening of the platform door in the present invention, the ZC system automatically establishes a safety protection area for the platform track, and this protection area requires manual operation to cancel, preventing the train from moving due to misoperation.

[0038] 3. When the signal system detects an abnormal opening of the platform door in the present invention, the ZC system automatically establishes a safety protection area for the platform track, preventing the train from entering the track area due to untimely manual operation, causing safety accidents, ensuring the property and personal safety of passengers, and improving the train operation safety.

[0039] 4.

Description of the Drawings

[0040] Figure 1 It is a schematic structural diagram of the device of the present invention;

[0041] Figure 2 This is the specific flowchart of the method of the present invention. Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0043] As Figure 1 shown, a protection device for abnormal opening of platform doors in the present invention is used in the FAM system. The protection device includes a zone controller ZC (Zone Controller), a vehicle controller CC (Carbone Controller), an interlocking system, a platform door system, and an ATS (Automatic Train Supervision) system. The interlocking system is communicatively connected to the zone controller ZC, the vehicle controller CC, the platform door system, and the ATS system respectively. The zone controller ZC is communicatively connected to the vehicle controller CC and the ATS system respectively. The zone controller ZC is built-in with a safety protection software module. When the zone controller ZC receives the loss of the door closing and locking information of a certain platform and does not receive the door enabling information calculated by the vehicle controller CC and / or the door opening instruction of the vehicle, the safety protection software module immediately establishes a protection area for the platform track area.

[0044] The information transmission process between each component is as follows:

[0045] The interlocking system collects the platform door closing and locking, and interlock release information through a relay interface and sends it to ZC. After the vehicle-mounted CC stops stably and accurately when the train enters the station, it calculates the door enabling (conditions for opening the door) and the door opening instruction for the car door / platform door. When the stop time ends, it calculates the door closing instruction for the car door / platform door. The door enabling information is sent to ZC, and the platform door opening and closing commands are sent to the interlocking system. After receiving the door opening and closing commands, the interlocking system forwards them to the platform door system through the relay interface. After receiving the door opening and closing commands from the interlocking system, the platform door system controls the opening and closing of the platform doors. The ATS system gives an alarm for abnormal opening of the platform doors and displays the safety protection of the platform track area on the central / station dispatching workstation terminal. The ATS system provides an operation to manually cancel the protection area on the central / station dispatching workstation. After the protection area is established for the platform track area, the staff can confirm that there is no risk and cancel the protection area. The ATS system provides operations to manually establish and cancel the protection area for the platform track area on the central / station dispatching workstation terminal.

[0046] The above is the introduction of the device embodiment. The following further illustrates the solution of the present invention through method embodiments.

[0047] As Figure 2 shown, the protection method of the platform screen door abnormal opening in the FAM system of the present invention includes the following steps:

[0048] Step S1: After the train enters the station and stops, after the on-vehicle CC detects that the train has stopped stably and accurately, it calculates the door opening enable and the door / platform screen door opening command, and sends the door opening enable information to the ZC and sends the platform screen door opening command to the interlocking system.

[0049] Step S2: After receiving the opening command, the interlocking system forwards it to the platform screen door system through the relay interface.

[0050] Step S3: After receiving the opening command, the platform screen door system executes the opening. After the platform screen door gives the relay of the platform screen door closing and locking interface of the interlocking system to drop, and the interlocking collects that the relay of the platform screen door closing and locking drops, it judges that the station door has been opened and forwards it to the ZC.

[0051] Step S4: When the stop time ends, the on-vehicle CC calculates the door / platform screen door closing command and sends the platform screen door closing command to the interlocking system.

[0052] Step S5: After receiving the closing command, the interlocking system forwards it to the platform screen door system through the relay interface.

[0053] Step S6: After receiving the closing command, the platform screen door system executes the closing. After the platform screen door is closed and locked, it gives the relay of the platform screen door closing and locking interface of the interlocking system to pick up. After the interlocking collects that the relay of the platform screen door closing and locking picks up, it judges that the station door has been closed and forwards it to the ZC.

[0054] Step S7: After the CC judges that the departure condition is met, it automatically controls the train to leave the station.

[0055] Step S8: When the train does not enter the station or does not stop accurately when entering the station, the platform screen door gives the relay of the platform screen door closing and locking interface of the interlocking system to drop. After the interlocking collects that the relay of the platform screen door closing and locking drops, it judges that the station door has been opened and forwards it to the ZC. If the ZC does not receive the door opening enable information sent by the CC, it judges that the platform screen door has been abnormally opened (even if the platform screen door returns instantly after opening), and establishes a safety protection area for the platform track area. The ZC judges that other trains have entered or approached the protection partition and will send a trigger for emergency braking to prevent normal trains from entering the platform track area as much as possible and prevent the occurrence of safety accidents.

[0056] Step S9: After the safety protection area of the platform track area is established, an alarm for abnormal opening of the platform screen door and a display of the safety protection of the platform track area will be given at the central / station ATS dispatching terminal.

[0057] Step S10. After the staff confirm that there are no personnel or foreign objects invading the track area through the camera or on-site inspection and ensure safety, they can manually cancel the safety protection area of the platform track at the central / station ATS dispatching terminal.

[0058] Step S11. When the staff find abnormalities in the platform track area, they can also operate on the central / station ATS dispatching workstation terminal to establish and cancel the safety protection area of the platform track.

[0059] Through the above process, the present invention greatly improves the automatic linkage level, response efficiency and train operation safety of the signal and platform door systems, and reduces the labor intensity of platform staff.
