Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a platform door control system, method and storage medium. Background Art

[0002] The interconnection of high-speed rail, subway and intercity line networks is the current development trend of the industry. There are scenarios where trains of different models stop at the same platform. Due to the different train compositions and numbers of doors, the platform doors need to open correspondingly when different models enter the station. The risk of passengers falling onto the tracks due to opening the wrong door should be avoided.

[0003] The traditional platform door SIG, PSL, and IBP interfaces use pure hard-wired electrical signals to connect to the PSC cabinet, and then the safety relay of the PSC cabinet completes the priority, self-locking and interlocking logic. If pure hard-wired and relay logic are used to implement multi-vehicle control instructions, there will be defects such as many cables, large size, high cost, difficult wiring, and doubled fault points.

[0004] Therefore, there is an urgent need for a platform door control system with a simple structure and low cost, which can effectively reduce the complexity of the system while ensuring reliability and safety. Summary of the invention

[0005] In view of this, the present application provides a platform door control system, method and storage medium, which can effectively reduce the complexity of the system while ensuring reliability and security. The technical solution is as follows.

[0006] In a first aspect, the present invention provides a platform door control system, the system comprising: a vehicle type selection module, a signal sending interface module and a control module;

[0007] A plurality of signal interfaces are provided between the signal sending interface module and the vehicle type selection module, and the vehicle type selection module is provided with an optocoupler circuit corresponding to the plurality of signal interfaces;

[0008] The signal sending interface module is used to control the corresponding target signal interface to close according to the vehicle type information of the target train after the target train enters the station;

[0009] The vehicle type selection module is used to turn on the corresponding target optocoupler circuit when the target signal interface is closed, generate a target door opening signal, and send the target door opening signal and the vehicle type information of the target train to the control module;

[0010] The control module is used to control the corresponding target platform door to open according to the vehicle type information of the target train when the target door opening signal and the vehicle type information of the target train are received simultaneously.

[0011] In an optional embodiment, the control module includes: an interface module, a processing module and a gate control unit; the interface module is used to forward the target door opening signal to the gate control unit; the processing module is used to forward the vehicle type category information of the target train to the gate control unit; the gate control unit is used to control the opening of the corresponding target platform door according to the vehicle type category information of the target train when the target door opening signal and the vehicle type category information of the target train are received at the same time.

[0012] In an optional embodiment, the signal issuing interface module includes: a signal system interface module, a platform control panel interface module and an emergency control panel interface module; the signal system interface module is connected to the signal system, and is used to receive a door opening command issued by the signal system; the platform control panel interface module is connected to the platform control panel, and is used to receive a door opening command issued by the platform control panel; the emergency control panel interface module is connected to the emergency control panel, and is used to receive a door opening command issued by the emergency control panel; the door opening commands issued by the signal system interface module, the platform control panel interface module and the emergency control panel interface module have different priorities.

[0013] In an optional embodiment, the signal sending interface module also includes: a priority judgment module; the priority judgment module is used to receive door opening commands issued by the signal system interface module, the platform control panel interface module and the emergency control panel interface module, and judge the priority of the door opening command to control the closure of the signal interface corresponding to the door opening command with high priority.

[0014] In an optional embodiment, the priority judgment module is also used to: when receiving multiple door opening instructions of the same priority, confirm that the multiple door opening instructions of the same priority are invalid, and control the signal interfaces corresponding to the multiple door opening instructions of the same priority to remain disconnected.

[0015] The platform door control system provided by the present invention has the following advantages.

[0016] The platform door control system of the present invention is used to control the platform door, and includes a vehicle type selection module, a signal sending interface module and a control module. A plurality of groups of signal interfaces are provided between the signal sending interface module and the vehicle type selection module, and the vehicle type selection module is provided with an optocoupler circuit corresponding to the plurality of groups of signal interfaces. The signal sending module includes a signal system interface module, a platform control panel interface module and an emergency control panel interface module. These three interface modules will close the corresponding signal interface according to the received door opening command, so that the corresponding optocoupler circuit in the vehicle type selection module is turned on, thereby sending a corresponding door opening signal. The vehicle type selection module will send the door opening signal and vehicle type category information to the control module. The control module includes an interface module, a processing module and a door control unit. The interface module forwards the door opening signal to the door control unit, and the processing module forwards the vehicle type category information to the door control unit. The door control unit will control the corresponding platform door to open only when the door opening signal and the vehicle type category information are received at the same time. In addition, since the signal sending interface module will receive door opening instructions of different priorities, the control module may receive multiple door opening signals at the same time, and these door opening signals may have different priorities. The system allows multiple door opening signals of different priorities to exist at the same time, but allows multiple door opening signals of the same priority to exist at the same time. If multiple door opening signals of the same priority are detected, these door opening signals are confirmed to be invalid and will not be processed. Therefore, the control module also sets a priority judgment module, which first determines whether these door opening signals are signals of the same priority. If they are signals of the same priority, these door opening signals are confirmed to be invalid. If they are signals of different priorities, the door opening signal with a higher priority is processed. When receiving a door opening signal, the door control unit will also determine whether the door opening signal is valid, that is, whether it is multiple signals of the same priority. Only when a valid door opening signal and vehicle type category information are received will the corresponding platform door be controlled to open. The platform door control system of the present invention has a simple structure, avoiding the doubling of the number of cables and relays caused by hard-wired signals of multiple models; it has high reliability, and uses isolated optocouplers on the external interface side to collect door opening signals of multiple models, which has low current, long life, and low failure rate; it has high safety, and the internal interface of this solution is based on the traditional platform door hard-wired control signal transmission mode. When the DCU receives the hard-wired door opening command and the door opening enable signal corresponding to the model, it can execute the door opening, avoiding the risk of accidental door opening; it has low cost, and compared with the method of realizing the transmission of control commands of multiple models by pure hard wires and relays, this solution has obvious cost advantages. It can effectively reduce the complexity of the system while ensuring reliability and safety.

[0020] In an optional embodiment, the door opening signal and the vehicle type category information are sent to a control module, and the control module is used to control the opening of the platform door corresponding to the vehicle type category information, including: forwarding the target door opening signal to a gate control unit through an interface module, and forwarding the vehicle type category information of the target train to the gate control unit through a processing module; and controlling the opening of the platform door corresponding to the vehicle type category information through the gate control unit.

[0021] In an optional embodiment, the method further includes: when receiving multiple door opening instructions, determining the priority of the multiple door opening instructions, and controlling the closure of a signal interface corresponding to a door opening instruction with a high priority.

[0022] In an optional embodiment, the method further includes: when receiving multiple door opening instructions of the same priority, confirming that the multiple door opening instructions of the same priority are invalid, and controlling the signal interfaces corresponding to the multiple door opening instructions of the same priority to remain disconnected.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0032] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0033] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0034] In an embodiment of the present application, "predefinition" can be achieved by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device). The present application does not limit its specific implementation method.

[0035] First, the terms involved in this application are introduced.

[0036] PSD: Safety door / platform door, composed of sliding door, fixed door, emergency door and end door, etc., installed on subway platform, the main purpose is to prevent passengers from contacting with train tracks and protect passengers; after the train enters the station, the platform door system receives the door opening signal sent by the signal system, and the PEDC controls the sliding door to open. Before the train leaves the station, the signal system will convert the door opening signal into a door closing signal, and the PEDC controls the sliding door to close;

[0037] ASD: Sliding doors are an important unit in the platform door composition. Passengers get on and off the train through sliding doors;

[0038] DCU: Door control unit, installed on the sliding door, receives control instructions from PEDC to execute door opening and closing, and feeds back the closing and locking status to PEDC;

[0039] PSC: Central interface panel, located in the platform door control room, is the main processing equipment for the platform door system interface. It is equipped with PEDC, terminal blocks, display and industrial computers, etc. Operation and maintenance personnel can query the working status and records of the platform door through the monitoring software on the industrial computer;

[0040] PEDC: Unit controller, processes control signals from signal systems, PSL and other interfaces, transmits control signals to all DCUs, monitors the status of all safety relays and DCUs, and transmits the status to the monitoring software;

[0041] SIG: Signal system. The opening and closing of platform doors are usually controlled by the signal system. When the train stops and is aligned with the platform door, the signal system will issue a command to open the platform door and the train door synchronously. Only after the train door and platform door are completely closed will the signal system allow the train to start and leave the platform.

[0042] PSL: Platform control panel, which has a higher control priority than the signal system. When the signal system fails or the platform door needs to be operated, the operation and maintenance personnel can operate the platform door through PSL;

[0043] IBP: Emergency control panel, installed in the station control room, with a higher control priority than PSL. When a fire occurs in the station or emergency evacuation is required, station staff can operate the IBP panel to open the platform door in whole or in part, so as to achieve the purpose of personnel evacuation and fire smoke exhaust;

[0044] PEDC-CPU: responsible for processing commands and data from the signal system (SIG), local control panel (PSL), emergency control panel (IBP) and other input sources;

[0045] PEDC-SIG: It is the interface module between PEDC and the signal system (SIG), and can also be used to receive commands and data from the local control panel (PSL) and the emergency control panel (IBP).

[0046] In recent years, urban rail transit has achieved tremendous development. However, due to factors such as design and planning concepts and historical causes, most rail transit lines are operated independently and adopt a "special car running on a special line" operation mode. This operation mode can no longer meet the diverse travel needs of passengers.

[0047] In order to further improve the utilization rate of line network resources, reduce construction and operation costs, and improve passenger travel efficiency, building a new operation mode of rail transit interconnection that is multi-level, integrated, and public transportation-oriented is an important development trend of rail transit. One of the main manifestations of the new operation mode of interconnection is the interconnection of multiple lines, including the interconnection between subway lines in the same city, the interconnection between urban railroads, the interconnection between urban railroads and subway lines, the interconnection between subway lines in different cities, and the interconnection between high-speed rail and intercity rail.

[0048] The interconnection of high-speed rail, subway and intercity line networks is the current development trend of the industry. There are scenarios where trains of different models stop at the same platform. Due to the different train compositions and numbers of doors, the platform doors need to open correspondingly when different models enter the station. The risk of passengers falling onto the tracks due to opening the wrong door should be avoided.

[0049] The following are typical requirements for mixed-use application scenarios: For example, the platform doors of a certain intercity rail transit station are designed to be compatible with the mixed operation modes of four-car and eight-car trains, with two types of CRH6 EMUs running at 160km / h and 200km / h, and have the technical conditions reserved for the reconnection of four-car EMUs. Among them, the 8-car model corresponds to full door opening for the two models with speeds of 160km / h and 200km / h; the 4-car model corresponds to the forward door opening of 4-carriage of 160km / h car, the forward door opening of 4-carriage of 200km / h car, the reverse door opening of 4-carriage of 160km / h car, and the reverse door opening of 4-carriage of 200km / h car. In addition, the door opening of 4-carriage reconnection of 160km / h car and 200km / h car is reserved.

[0050] The traditional platform door SIG, PSL, and IBP interfaces use pure hard-wired electrical signals to connect to the PSC cabinet, and then the safety relay of the PSC cabinet completes the priority, self-locking and interlocking logic. If pure hard-wired and relay logic are used to implement multi-vehicle control instructions, there will be defects such as many cables, large size, high cost, difficult wiring, and doubled fault points.

[0051] In order to solve the defects of the existing platform door control method, the present invention provides a platform door control system that combines hard-wired signals with software control to simplify wiring while ensuring the reliability and safety of the system.

[0052] The platform door control system provided by the embodiment of the present invention is as follows: Figure 1As shown, it includes: a vehicle type selection module, a signal sending interface module and a control module; a plurality of groups of signal interfaces are arranged between the signal sending interface module and the vehicle type selection module, and the vehicle type selection module is provided with optocoupler circuits corresponding to the plurality of groups of signal interfaces.

[0053] The signal sending interface module is used to control the closure of the corresponding target signal interface according to the vehicle type information of the target train after the target train enters the station.

[0054] Optionally, the signal sending interface module includes: a signal system interface module, a platform control panel interface module and an emergency control panel interface module; the signal system interface module is connected to the signal system, and is used to receive the door opening command issued by the signal system; the platform control panel interface module is connected to the platform control panel, and is used to receive the door opening command issued by the platform control panel; the emergency control panel interface module is connected to the emergency control panel, and is used to receive the door opening command issued by the emergency control panel; the door opening commands issued by the signal system interface module, the platform control panel interface module and the emergency control panel interface module have different priorities.

[0055] Optionally, the signal sending interface module also includes: a priority judgment module; the priority judgment module is used to receive door opening commands issued by the signal system interface module, the platform control panel interface module and the emergency control panel interface module, and judge the priority of the door opening command to control the closure of the signal interface corresponding to the door opening command with a high priority.

[0056] Specifically, the priority judgment module is also used to: when receiving multiple door opening instructions of the same priority, confirm that the multiple door opening instructions of the same priority are invalid, and control the signal interfaces corresponding to the multiple door opening instructions of the same priority to remain disconnected.

[0057] The vehicle type selection module is used to turn on the corresponding target optocoupler circuit when the target signal interface is closed, generate a target door opening signal, and send the target door opening signal and the vehicle type information of the target train to the control module;

[0058] The control module is used to control the corresponding target platform door to open according to the vehicle type information of the target train when the target door opening signal and the vehicle type information of the target train are received simultaneously.

[0059] Optionally, the control module includes: an interface module, a processing module and a gate control unit; the interface module is used to forward the target door opening signal to the gate control unit; the processing module is used to forward the vehicle type category information of the target train to the gate control unit; the gate control unit is used to control the opening of the corresponding target platform door according to the vehicle type category information of the target train when the target door opening signal and the vehicle type category information of the target train are received at the same time.

[0060] In summary, the platform door control system provided by the embodiment of the present invention is used to control the platform door, including a vehicle type selection module, a signal sending interface module and a control module. A plurality of groups of signal interfaces are provided between the signal sending interface module and the vehicle type selection module, and the vehicle type selection module is provided with an optocoupler circuit corresponding to the plurality of groups of signal interfaces. The signal sending module includes a signal system interface module, a platform control panel interface module and an emergency control panel interface module. These three interface modules will close the corresponding signal interface according to the received door opening command, so that the corresponding optocoupler circuit in the vehicle type selection module is turned on, thereby sending a corresponding door opening signal. The vehicle type selection module will send the door opening signal and the vehicle type category information to the control module. The control module includes an interface module, a processing module and a door control unit. The interface module forwards the door opening signal to the door control unit, and the processing module forwards the vehicle type category information to the door control unit. The door control unit will control the corresponding platform door to open only when the door opening signal and the vehicle type category information are received at the same time. In addition, since the signal sending interface module will receive door opening instructions of different priorities, the control module may receive multiple door opening signals at the same time, and these door opening signals may have different priorities. The system allows multiple door opening signals of different priorities to exist at the same time, but allows multiple door opening signals of the same priority to exist at the same time. If multiple door opening signals of the same priority are detected, these door opening signals are confirmed to be invalid and will not be processed. Therefore, the control module also sets a priority judgment module, which first determines whether these door opening signals are signals of the same priority. If they are signals of the same priority, these door opening signals are confirmed to be invalid. If they are signals of different priorities, the door opening signal with a higher priority is processed. When receiving a door opening signal, the door control unit will also determine whether the door opening signal is valid, that is, whether it is multiple signals of the same priority. Only when a valid door opening signal and vehicle type category information are received will the corresponding platform door be controlled to open. The platform door control system of the present invention has a simple structure, avoiding the doubling of the number of cables and relays caused by hard-wired signals of multiple models; it has high reliability, and uses isolated optocouplers on the external interface side to collect door opening signals of multiple models, which has low current, long life, and low failure rate; it has high safety, and the internal interface of this solution is based on the traditional platform door hard-wired control signal transmission mode. When the DCU receives the hard-wired door opening command and the door opening enable signal corresponding to the model, it can execute the door opening, avoiding the risk of accidental door opening; it has low cost, and compared with the method of realizing the transmission of control commands of multiple models by pure hard wires and relays, this solution has obvious cost advantages. It can effectively reduce the complexity of the system while ensuring reliability and safety.

[0061] Here we take an actual platform door control system logic structure as an example to illustrate the above platform door system. Figure 1 The signal sending interface module includes Figure 1The signal system, PSL and IBP modules in the control module adopt the PEDC-CPU module for the processing module and the PEDC-SIG module for the interface module.

[0062] The signal system, PSL and IBP form a three-level control, and the priority order is: signal system <PSL <IBP. Each level is only allowed to send one type of door opening signal at each time. Multiple types of door opening signals are not allowed to be valid at the same level, but different levels are allowed to have different door opening commands. The system only executes the highest priority door opening command. When there are multiple door opening signals at the same level, the system considers the door opening signal invalid and maintains the last execution status unchanged.

[0063] There are several groups of signal interfaces between the signal sending interface module and the vehicle model selection module. Figure 1 For example, there are eight groups of door opening command interfaces between the signal system and the platform door vehicle model selection module, and each interface is 2 pairs of dry contact signals. Each door opening signal input terminal is two pairs of dry contact signals. When the two pairs of contacts are closed, the door opening signal is valid, and when they are disconnected, the door opening signal is invalid.

[0064] Before the train enters the station, it will send a corresponding door opening signal, i.e., a dry contact closing signal, to the platform door through the signal system according to its vehicle type. After the train enters the station, the signal system will control the door opening command interface contacts corresponding to the vehicle type selection module to close; at this time, the two pairs of closed dry contacts will conduct the detection signal optocoupler input end of the vehicle type selection module, and the vehicle type selection module will detect that the optocoupler is turned on and it is a valid signal.

[0065] After the door opening signal is generated, the vehicle type signal is sent to the PEDC-CPU board through the RS485 communication interface, and a 24V door opening signal is sent to the PEDC-SIG input interface. Finally, the DCU door opening command input interface receives the 24V door opening signal sent from the PEDC-SIG output interface, and receives the current train model information sent by the PEDC-CPU through the CAN bus interface. When the door opening command has a 24V signal and the current train type is the type that the DCU needs to open the door, the DCU executes the door opening. The control logic of the PSL and IBP modules is similar to the signal system, which will not be repeated here.

[0066] For example, suppose the model category of train A corresponds to Figure 1 The door opening signal 3 in the figure corresponds to all odd-numbered platform doors. Figure 1The door control units DCU1, DCU3, DCU5...DCU23 in the station. Before train A enters the station, the signal system recognizes that it needs to send the door opening signal 3. After train A enters the station, the signal system controls the dry contact corresponding to the door opening signal 3 to close. Then, the door opening signal 3 and the vehicle type of train A are sent to the door control units DCU1, DCU3, DCU5...DCU23 through the control module to control the opening of these door control units. When train A leaves the station, the signal system sends a door closing signal to close all platform doors. Similarly, assuming that the vehicle type of train B corresponds to Figure 1 The door opening signal 7 in the figure, the platform doors corresponding to the door opening signal 7 are the platform doors corresponding to the door control units DCU4, DCU8, DCU12, DCU16, DCU20, and DCU24. When train B enters the station, the system sends the door opening signal 7 to control the platform doors corresponding to the door control units DCU4, DCU8, DCU12, DCU16, DCU20, and DCU24 to open. When train B leaves the station, the signal system sends the door closing signal to close all platform doors.

[0067] In summary, the platform door control system of this example has a simple structure, avoiding the doubling of the number of cables and relays caused by hard-wired signals of multiple models; high reliability, the external interface side uses isolated optocouplers to collect door opening signals of multiple models, with low current, long life and low failure rate; high safety, the internal interface of this solution is based on the traditional platform door hard-wired control signal transmission mode, when the DCU receives the hard-wired door opening command and the corresponding door opening enable signal of the model, it can execute the door opening, avoiding the risk of accidental door opening; low cost, compared with the method of realizing the transmission of control commands of multiple models by pure hard wires and relays, this solution has obvious cost advantages. It can effectively reduce the complexity of the system while ensuring reliability and safety.

[0068] Based on the above embodiment, the embodiment of the present invention further provides a platform door control method, which uses the platform door control system provided by the above embodiment. The method flow of the method is as follows: Figure 2 As shown, the following steps are included:

[0069] S201. When a door opening command is received, the corresponding target signal interface is controlled to close according to the vehicle type information indicated by the door opening command to generate a door opening signal.

[0070] Optionally, in step S201, the target door opening signal is forwarded to the gate control unit through the interface module, and the vehicle type category information of the target train is forwarded to the gate control unit through the processing module; the platform door corresponding to the vehicle type category information is controlled to open by the gate control unit.
