Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit control, and in particular relates to a platform-associated platform screen door control method and system. Background Art

[0002] With the rapid development of urban rail transit, platform shield doors, as a type of isolation equipment between platform areas and track areas, play an important role in heat preservation and dust prevention, passenger isolation, and safety. In actual operation, when a train enters a station to stop and drop off passengers or leaves a station to pick up passengers, the doors will be "opened" or "closed". At this time, if the platform shield doors cannot be "opened" or "closed" at the same time, it will not only affect passengers getting on and off the train, but also bring about the danger of passengers being caught in the gap between the door and the platform shield door and falling off the platform. Therefore, realizing the linkage function between the door and the platform platform shield door is of great significance in saving operating costs, improving operating efficiency, and ensuring the safety of passengers getting on and off the train.

[0003] There are many methods for realizing the linkage function between doors and shielding doors in the currently disclosed technologies. A shielding door switch control device and a door shielding door linkage control method are proposed in Chinese patent CN104847210A. The method is to obtain the door movement state information through a sensor and realize the shielding door switch linkage function corresponding to the door through a control module. The efficient and reliable wireless transmission communication system is abandoned, and the sensor is directly used to collect the door state information. Although the linkage function between the doors of trains with a smaller number of formations than the platform shielding doors and the corresponding platform shielding doors is solved, the door induction sensors arranged on the platform are difficult to apply to complex rail stations such as underground tunnels or viaducts, and have poor scalability. They are easily disturbed by environmental factors such as light, obstructions, magnetic fields, and sound waves, and the wrong door opening information is collected, thereby performing the wrong shielding door linkage operation, which is easy to cause safety accidents.

[0004] In addition, Chinese patent CN102127998A proposes a platform screen door linkage method based on a wireless communication train control system, which is mainly initiated by the train and sends the platform screen door opening and closing command to the ground system through the wireless communication network. The ground system implements the platform screen door linkage function through the interface with the platform screen door control system. Although an efficient and reliable wireless communication transmission system is adopted, which has the characteristics of high efficiency and flexibility, it can only realize the linkage function of all platform screen doors opening or closing at the same time. Figure 1 As shown in the figure, when the train doors 01-06 are opened, the platform screen doors 01-08 are linked at the same time, which may easily cause the risk of passengers falling onto the platform from the platform screen doors 07 and 08. The platform screen doors that are opened by mistake may cause the passengers to fall onto the platform, causing safety accidents. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] Terminology explanation: RSSP-I is a TCP / IP-based network protocol used to implement point-to-point data exchange. It supports a variety of data types, including text, images, audio, etc., and can use encryption technology to ensure data security.

[0024] RSSP-II is a network protocol based on HTTP, mainly used to implement Web services. RSSP-II supports multiple data formats, including HTML, XML, JSON, etc., and can achieve secure data transmission through SSL / TLS protocol.

[0025] like Figure 2 As shown, a platform-associated screen door control system according to an embodiment of the present disclosure includes: On-board system ATP, ground zone control system ZC, ground interlocking system CI and shield door system PSD.

[0026] The on-board system ATP is connected to the ground zone control system ZC via a wireless communication network; the wireless communication network adopts the RSSP-I communication protocol or the RSSP-II communication protocol; the ground zone control system ZC is connected to the ground interlocking system CI via a wired communication network; the wired communication network adopts the RSSP-I communication protocol.

[0027] The on-board system ATP is used to generate a platform-associated screen door switch command list, which is used to send it to the ground zone control system ZC through a wireless communication network to determine whether the departure conditions are currently met; when it is determined that the train doors and platform screen doors are both closed, the departure conditions are met and the train is dispatched. In this embodiment, the switch status of the platform screen door is judged by the screen door switch status list fed back by the screen door system PSD.

[0028] The ground zone control system ZC is used to generate a platform-associated platform screen door control list according to the platform-associated platform screen door switch command list, and transmit the platform-associated platform screen door control list to the ground interlocking system CI through a wired communication network; In this embodiment, the platform shielding door data information configured by the ground zone control system ZC includes the platform shielding door external number, the platform shielding door internal number and the line left and right side attributes.

[0029] The ground interlocking system CI is used to perform the switch operation of the platform-associated platform shielding door through the IO relay interface of the platform shielding door system PSD according to the platform-associated platform shielding door control list; In this embodiment, the ground zone control system ZC and the ground interlocking system CI interactive interface are configured with a common data correspondence table, which includes the equipment information within the jurisdiction of the ground zone control system.

[0030] The platform screen door system PSD is used to feed back the switch status list of the platform-associated platform screen doors to the ground interlocking system CI, the ground interlocking system CI forwards it to the ground zone control system ZC, and the ground zone control system ZC forwards it to the vehicle-mounted system ATP.

[0031] Based on the above system, Figure 3 As shown, the embodiment of the present disclosure also provides a platform-associated platform screen door control method corresponding to the above system, including: Step 1: When the train envelope overlaps with the platform and the train stops accurately and steadily, the onboard system ATP sends the train position, train running direction and platform-related screen door switch command list to the ground zone control system ZC through the wireless communication network; In this embodiment, the platform-associated screen door switch command list includes the screen door external number. The screen door external number is used for interaction between the train and the platform interface. Each screen door on the platform has a one-to-one corresponding screen door external number. The external numbers of all screen doors in the entire line are configured in the on-board system ATP. The screen door external number of each screen door on a running line is unique.

[0032] Step 2: the ground zone control system ZC matches the platform-associated platform screen door according to the platform-associated platform screen door switch command list, determines the line left and right side attributes of the corresponding platform-associated platform screen door according to the train position and the train running direction, performs a mutual exclusion check on the platform-associated platform screen door switch command list through the line left and right side attributes of the corresponding platform-associated platform screen door, and then determines the platform-associated platform screen door control list. The platform-associated platform screen door control list is sent to the ground interlocking system CI through the wired communication network; In this embodiment, if Figure 4 As shown, the platform shielding door data information configured by the ground zone control system ZC includes the internal number of the platform shielding door, the external number of the platform shielding door and the left and right side attributes of the line.

[0033] It should be noted that a common data correspondence table is configured between the ground zone control system ZC and the ground interlocking system CI, and the data correspondence table includes information of all equipment under the jurisdiction of the ground zone control system ZC, such as shield doors, emergency closing buttons, switches, etc.

[0034] The internal number of the platform screen door is used for communication within the jurisdiction of the ground zone control system ZC; the internal number of the platform screen door corresponds to the external number of the platform screen door. The left and right side attributes of the line are determined according to the direction of travel of the train and the platform location. Figure 4 In the example, the train travels from right to left, the platform is located on the right side of the train, and the line left and right side attributes of the platform-associated platform platform screen door are on the right side, that is, the platform platform screen door is located on the right side of the train running line.

[0035] Step three, the ground interlocking system CI finds the platform-associated shielding door according to the platform-associated shielding door control list and the shared data correspondence table, and performs switch operation on the platform-associated shielding door through the IO relay interface of the shielding door system PSD.

[0036] Step 4: the platform-associated platform-associated door system PSD feeds back the switch status list of the platform-associated platform-associated door to the ground interlocking system CI, and the ground interlocking system CI sends it to the ground zone control system ZC through the ground wired communication network.

[0037] Step 4: the ground zone control system ZC sends the switch status list of the platform-associated screen doors to the vehicle-mounted system ATP through the wireless security network.

[0038] Step 5: The on-board system ATP determines whether the train is departing based on the switch status list of the platform-associated screen doors and the train door status information.

[0039] Example 1 like Figure 5-6 As shown, there are n platforms within the jurisdiction of the ground zone control system ZC, each platform includes 8 platform screen doors, the train entering the station is a 6-car formation, and the platform is located on the right side of the train running direction. The control process of the platform screen door is as follows: Step 1: After the train stops accurately and steadily, the onboard system ATP sends the train position, train direction and platform-related screen door switch command list to the ground zone control system ZC through the wireless communication network. Since the platform 1 screen door is located on the right side of the train and the train length is less than the radiation range of the platform 1 screen door, only the right screen doors 01-06 are included in the data configuration table of the onboard system ATP, and the right screen doors 07 and 08 are not included.

[0040] Step 2: The ground zone control system ZC includes the external numbers of the platform screen doors, the internal numbers of the platform screen doors, and the left and right side attributes of the line of N platforms in the data configuration table; the ground zone control system ZC finds the platform screen door 01-06 in the platform 1 according to the platform-associated platform screen door switch command list, and configures the platform screen door 01-06 as the right side attribute of the line according to the train position and the train running direction. The platform-associated platform screen door switch command list is subjected to a mutual exclusion check according to the right side attribute of the line of the platform screen door 01-06. Then, the internal numbers of the platform screen doors 01-06 are obtained, and the platform-associated platform screen door control list is generated, and the platform-associated platform screen door control list is sent to the ground interlocking system CI through the ground wired communication network.

[0041] Step 3: the ground interlocking system CI finds the platform-associated shielding door according to the platform-associated shielding door control list, and performs the switch operation of the platform-associated shielding door through the IO relay interface of the shielding door system PSD.

[0042] Step 4: the platform shielding door system PSD feeds back the switch status list of the platform shielding door to the ground interlocking system CI, and the ground interlocking system CI sends the switch status list of the platform shielding door to the ground zone control system ZC through the ground wired communication network.

[0043] Step 5: The ground zone control system ZC sends the switch status list of the platform-associated platform screen doors to the vehicle-mounted system ATP through the wireless communication network.

[0044] Step 5: The on-board system ATP determines whether the train meets the departure conditions based on the switch status list of the platform-associated screen doors and the switch status information of the train doors.

The platform screen doors 01-06 in the ground zone control system ZC are configured as platform platform screen doors 01-06 with the right side of the line attribute.

[0046] The on-board system ATP sends the platform-associated screen door switch command list to the ground zone control system ZC through the wireless communication network.

[0047] The ground zone control system ZC generates a platform-associated platform screen door control list according to the platform-associated platform screen door switch command list, and performs a mutual check on the platform-associated platform screen door control list through the right-side attributes of the platform screen door line; then the platform-associated platform screen door control list is sent to the ground interlocking system CI.

[0048] The ground interlocking system CI finds the platform-associated platform shield door control list and drives the IO relay interface of the platform shield door 01-06 to perform the switch operation on the platform shield door 01-06.

[0049] The shield door system PSD sends the switch status list of shield doors 01-06 to the ground interlocking system CI, and the ground interlocking system CI forwards the switch status list of shield doors 01-06 to the on-board system ATP through the ground zone control system ZC.

The platform screen doors 01-06 in the ground zone control system ZC are configured as the left side of the line.

[0052] The on-board system ATP sends the platform-associated screen door switch command list to the ground zone control system ZC through the wireless communication network.

[0053] The ground zone control system ZC generates a platform-associated platform screen door control list according to the platform-associated platform screen door switch command list, and performs a mutual check on the platform-associated platform screen door control list through the right-side attributes of the platform screen door line; then the platform-associated platform screen door control list is sent to the ground interlocking system CI.

[0054] The ground interlocking system CI finds the shielding door 01-06 through the platform-associated shielding door control list; through the IO relay interface of the shielding door 01-06, the shielding door 01-06 is switched on and off.

[0057] Example 4 like Fig. 9As shown in the figure, the train runs from right to left and is a 6-car train. The platforms are located on both sides of the train. Platform 1 is equipped with platform screen doors 01-04, and platform 2 is equipped with platform screen doors 05-08. The platform-related platform screen door switch command list generated by the onboard system ATP includes left-side platform screen doors 01-04 and right-side platform screen doors 05-06. The platform screen door configuration in the ground zone control system ZC is that platform 1 platform screen doors 01-04 are on the left side of the line, and platform 2 platform screen doors 05-06 are on the right side of the line.

[0058] The on-board system ATP sends the platform-associated screen door switch command list to the ground zone control system ZC through the wireless communication network.

[0059] The ground zone control system ZC generates a platform-associated platform screen door control list according to the platform-associated platform screen door switch command list, and cross-checks the platform-associated platform screen door control list through the line left and right side attributes of the platform screen door; then the platform-associated platform screen door control list is sent to the ground interlocking system CI.
