Description

Technical Field

[0001] This invention relates to the field of rail transit train control technology, and in particular to a dual-end train door opening control system and method. Background Technology

[0002] Road transport vehicles (such as buses) typically have only one driver's cab, usually operate in one direction, and park close to the roadside. The driver controls the door to open on the right side of the cab, and there is usually no door on the left side. For special scenarios like island platforms, a door may be installed on the left side. Unlike rail transit, road transport vehicles do not typically consist of multiple vehicles forming a train, nor do they have centralized door opening. Usually, each door has a separate switch on the driver's console for independent control. When stopping at a station, the driver usually decides whether to open the left or right door by observing the platform.

[0003] Rail transit trains (such as subway cars) are typically composed of multiple cars, each with a driver's cab at both ends. They can operate without turning around at the end, only needing to reverse direction; therefore, doors must be installed on both sides of the train. The opening and closing of both doors are authorized and controlled via a signaling system. Doors on the side with the platform will only be allowed to open when the train meets the opening and closing conditions. Doors on the side without the platform will not be allowed to open. If a door opens incorrectly, passengers could fall onto the tracks, leading to a serious safety accident.

[0004] In special circumstances, such as fires, terrorist attacks, or other situations requiring rapid escape, or when door permission signals malfunction and necessitate forced door opening, rail transit vehicles typically have a door permission bypass switch with a protective cover installed in the control cabinet or at a location on the driver's cab. Activating this bypass switch requires requesting permission from the dispatch center and obtaining authorization before the switch can be opened, thus forcibly issuing a door opening permission signal. For rubber-tired trains operating on road surfaces, the vehicles possess the characteristics of rail trains: they have dual-end driving capabilities, do not require turning around, have doors at both ends, have multiple doors throughout the train, and all doors are centrally controlled by the driver. The operating routes and environment are similar to those of bus routes: they run on road surfaces, the platform height difference from the ground is only about 300mm, and other vehicles will be operating in other lanes of the road. Due to these two characteristics, rubber-tired trains have higher safety requirements compared to buses, and their control and management methods are comparable to rail transit.

[0005] Therefore, providing a dual-end train door opening control system and method that can effectively improve the safety of passengers during the operation of rubber-tired trains is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a dual-end train door opening control system and method. The system has a simple structure, is safe, effective, reliable and easy to operate, and can effectively improve the safety of passengers, thereby reducing safety problems caused by train door opening.

[0007] Based on the above objectives, the technical solution provided by the present invention is as follows:

[0008] A dual-end train door opening control system, comprising a door control console, a vehicle controller, signaling devices, and a dispatch control center;

[0009] The two door control consoles are symmetrically arranged at both ends of the train interior;

[0010] The dispatch control center is connected to the door control console via the signal device;

[0011] The vehicle controller is located between the signal device and the door control panel;

[0012] The dispatch control center is used to send a door opening permission signal to the door control console via the signal device;

[0013] The vehicle controller is used to collect door opening parameters and send the door opening parameters to the door control panel;

[0014] The door control console is used to control the opening of the train doors according to the opening parameters and the opening permission signal.

[0015] Preferably, the door control console includes: a signal acquisition module, a door control module, and an instrument display module;

[0016] The signal acquisition module is connected to the door control module and the instrument display module respectively;

[0017] The signal acquisition module is used to acquire the door opening permission signal and the door opening parameters, and control the door control module to open / close according to the door opening permission signal and the door opening parameters;

[0018] The door control module is used to control the door to open according to the control command of the signal acquisition module, and to collect relevant parameters of the door opening.

[0019] The instrument display module is used to display the door opening parameters and the door opening permission signal.

[0020] Preferably, the door control module includes: a door switch and a door switch signal submodule;

[0021] The door switch is connected to the signal acquisition module and the door switch signal submodule, respectively;

[0022] The door switch is used to control the opening and closing of the door;

[0023] The door switch signal submodule is used to collect door switch parameters.

[0024] Preferably, the door control panel further includes: an emergency module;

[0025] The emergency module is connected to the door control module and the instrument display module respectively;

[0026] The emergency module is used to generate and send an emergency signal to the door control module when the signal acquisition module malfunctions or the train is in a preset special state.

[0027] Preferably, the emergency module includes: a judgment submodule and a signal generation submodule;

[0028] The judgment submodule is connected to the door switch signal submodule and the signal generation submodule, respectively;

[0029] The judgment submodule is used to perform multiple judgments according to the door opening parameters and the door opening parameters, and generate a first emergency judgment result.

[0030] The signal generation submodule is used to generate the emergency signal based on the first emergency judgment result.

[0031] Preferably, the emergency module further includes: a signal cancellation submodule;

[0032] The signal cancellation submodule is connected to the judgment submodule;

[0033] The judgment submodule is also used to perform multiple judgments according to the door opening parameters and the door opening parameters, and generate a second emergency judgment result.

[0034] The signal cancellation submodule is used to cancel the emergency signal based on the second emergency judgment result.

[0035] A method for controlling the opening of doors on a train at both ends, implemented based on any of the aforementioned dual-end train door opening control systems, is characterized by comprising the following steps:

[0036] S1. Obtain the door opening permission signal;

[0037] S2. Collect door opening parameters;

[0038] S3. Control the train doors to open according to the door opening permission signal and the door opening parameters.

[0039] Preferably, if obtaining the door opening permission signal fails or the train is in a preset special state, the following steps are included before step S2:

[0040] S11. Obtain emergency signals;

[0041] Specifically, step S3 involves controlling the train doors to open based on the emergency signal and the door opening parameters.

[0042] Step S11 includes the following steps:

[0043] Obtain the door opening / closing parameters;

[0044] Determine whether the train has stopped based on the stated door opening parameters;

[0045] If so, then determine whether the door switch pressing time is within the range of the preset first time and the preset second time based on the door switch parameters;

[0046] If so, then the emergency signal is generated;

[0047] Based on the door switch parameters, determine whether the door switch has been released;

[0048] If so, then send the generated emergency signal.

[0049] Preferably, if the train leaves the preset special state and the emergency signal exists, the following steps are included after step S11 and before step S1:

[0050] S12. Delete the emergency signal;

[0051] Step S12 includes the following steps:

[0052] Obtain the duration of the emergency signal;

[0053] Based on the door opening and closing parameters, determine whether the corresponding door has been opened.

[0054] If not, then determine whether the door switch has failed based on the door switch parameters.

[0055] If not, determine whether the duration of the emergency signal exceeds a preset third time.

[0056] If not, then determine whether the train's traction speed is greater than zero speed based on the aforementioned door opening parameters;

[0057] If so, then the emergency signal is eliminated.

[0058] The dual-end train door opening control system provided by this invention includes a door control console, a vehicle controller, a signaling device, and a dispatch control center. The door control console, vehicle controller, and signaling device are located inside the rubber-tired train, while the dispatch control center is located near the ground along the train track. The door control console is located at both ends of the train interior, i.e., in the driver's cab. The signaling device is located inside the vehicle, with one end connected to the door control console and the other end connected to the dispatch control center. The vehicle controller is located between the signaling device and the door control console.

[0059] During operation, the dispatch control center sends a door opening permission signal to the door control console via a signaling device. The door opening permission signal indicates that the door on one side of the rubber-tired train is allowed to be opened. The vehicle controller collects door opening parameters such as zero speed signal, brake application signal, and door opening command signal, and sends the door opening parameters to the door control console. The door control console summarizes the door opening parameters and the door opening permission signal, and controls the corresponding train door to open according to the door opening parameters and the door opening permission signal.

[0060] This invention requires acquiring opening parameters and an opening permission signal when opening a train door. The zero-speed signal in the opening parameters confirms that the train speed has reached zero; the braking application signal in the opening parameters confirms that the train has applied brakes; and the opening command signal in the opening parameters confirms that the train is ready to open the doors. In summary, this system determines that the train is ready to open the doors based on the opening parameters, and then opens the corresponding door based on the opening permission signal issued by the dispatch control center. Compared to existing technologies, this invention does not directly open the door after receiving the opening permission signal. Instead, it waits until it receives the opening parameters collected by the vehicle controller, confirms that the train is ready to open the doors, and then opens the door on the corresponding side based on the opening permission command. This effectively improves passenger safety and reduces safety issues caused by train door opening.

[0061] The present invention also provides a method for controlling the opening of doors on a train at both ends. Since it solves the same technical problem as the control system for opening doors on a train at both ends and belongs to the same technical concept, it should have the same beneficial effects, and will not be described in detail here.

[0069] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0070] The embodiments of this invention are written in a progressive manner.

[0071] This invention provides a dual-end train door opening control system and method. It primarily addresses the technical problem in the prior art where opening the door upon receiving a single signal reduces passenger safety.

[0072] like Figure 1 As shown, a dual-end train door opening control system includes a door control console, a vehicle controller, a signaling device, and a dispatch control center.

[0073] Two door control consoles are symmetrically located at both ends of the train interior;

[0074] The dispatch control center is connected to the door control console via signaling devices;

[0075] The vehicle controller is located between the signal device and the door control panel;

[0076] The dispatch control center is used to send door opening permission signals to the door control console via signaling devices;

[0077] The vehicle controller is used to collect door opening parameters and send them to the door control panel.

[0078] The door control panel is used to control the opening of train doors based on opening parameters and opening permission signals.

[0079] The dual-end train door opening control system provided by this invention includes a door control console, a vehicle controller, a signaling device, and a dispatch control center. The door control console, vehicle controller, and signaling device are located inside the rubber-tired train, while the dispatch control center is located near the ground along the train track. The door control console is located at both ends of the train interior, i.e., in the driver's cab. The signaling device is located inside the vehicle, with one end connected to the door control console and the other end connected to the dispatch control center. The vehicle controller is located between the signaling device and the door control console.

[0080] During operation, the dispatch control center sends a door opening permission signal to the door control console via a signaling device. The door opening permission signal indicates that the door on one side of the rubber-tired train is allowed to be opened. The vehicle controller collects door opening parameters such as zero speed signal, brake application signal, and door opening command signal, and sends the door opening parameters to the door control console. The door control console summarizes the door opening parameters and the door opening permission signal, and controls the corresponding train door to open according to the door opening parameters and the door opening permission signal.

[0081] In this embodiment, the door control consoles are located in the driver's cabs at both ends of the rubber-tired train, with one door control console corresponding to the left door of the train and the other door control console corresponding to the right door of the train; the signal device specifically adopts a wireless transmission device; and the vehicle controller specifically adopts a VCU.

[0082] It's important to note that wireless transmission devices, also known as wireless audio / video transmitters, are devices that transmit audio and video signals from a signal source (computer or HD playback device) to a remote HDTV or HD projector. They require no software installation, are plug-and-play, and can achieve 1080p / 60p and 3D wireless transmission. Wireless transmission devices rely on WHDI technology, short for Wireless Home Digital Interface. Based on the mature 5GHz free frequency band, with a bandwidth of approximately 20-40Mbps, it theoretically achieves a transmission rate of up to 3Gbps. It supports uncompressed 720p / 1080i / 1080p resolution, 60Hz refresh rate HD video, and 7.1 channel, 24bit / 192kHz sampling rate lossless audio transmission. It supports HDCP 2.0 digital rights management protocol, has a coverage range of up to 30 meters, latency of less than 1 millisecond, and can penetrate and pass through walls. Given the diversity of wired and wireless devices, the aim is to achieve compatible connectivity for all devices through a single standard.

[0083] The Vehicle Control Unit (VCU), as the central control unit of the train, is the core of the entire control system. The VCU collects motor and battery status data, accelerator pedal signals, brake pedal signals, actuator and sensor signals, and, after comprehensively analyzing the driver's intentions and making corresponding judgments, monitors the actions of the lower-level component controllers. It is responsible for the train's normal operation, brake energy feedback, energy management of the entire vehicle's drive system and power battery, network management, fault diagnosis and handling, and vehicle status monitoring, thereby ensuring the vehicle operates normally and stably with good power performance, high economy, and high reliability.

[0084] The zero-speed signal, brake application signal, door opening command signal, and traction command signal in the door opening parameters are all obtained by the VCU in the train through detection and judgment.

[0085] like Figure 2 As shown, preferably, the door control console includes: a signal acquisition module, a door control module, and an instrument display module;

[0086] The signal acquisition module is connected to both the door control module and the instrument display module.

[0087] The signal acquisition module is used to acquire the door opening permission signal and door opening parameters, and control the door control module to open / close according to the door opening permission signal and door opening parameters;

[0088] The door control module is used to control the door to open according to the control commands from the signal acquisition module, and to collect relevant parameters for door opening.

[0089] The instrument display module is used to display door opening parameters and door opening permission signals.

[0090] In practical application, the door control console is equipped with a signal acquisition module, a door control module, and an instrument display module. The signal acquisition module is connected to both the door control module and the instrument display module. During operation, the signal acquisition module receives door opening parameters sent by the vehicle controller and door opening permission signals sent by the dispatch control center via signal devices. It then combines these signals to generate control commands and sends them to the door control module to open / close the door. The door control module, based on the received control commands, controls the door to open and collects relevant door opening parameters. The signal acquisition module also sends the acquired door opening parameters and permission signals to the instrument display module for operator reference.

[0091] Preferably, the door control module includes: a door switch and a door switch signal submodule;

[0092] The door switch is connected to the signal acquisition module and the door switch signal submodule, respectively.

[0093] Door switches are used to control the opening and closing of car doors;

[0094] The door switch signal submodule is used to collect door switch parameters.

[0095] In practical application, the door control module is equipped with a door switch and a door switch signal submodule. The door switch is connected to both the signal acquisition module and the door switch signal submodule. During operation, the door control module receives control commands, determines which side of the train should open the door, and how many doors should be opened, then controls the door switch to open, and the door opens. After passengers disembark, the door switch is controlled to close, and the door closes. During the door opening process, the door switch signal submodule collects relevant parameters of the door switch.

[0096] In this embodiment, the specific parameters of the door switch are: door switch pressing time, door switch release status, door opening status, and door switch failure status.

[0097] like Figure 3 As shown, preferably, the door control panel also includes an emergency module;

[0098] The emergency module is connected to both the door control module and the instrument display module.

[0099] The emergency module is used to generate and send an emergency signal to the door control module when the signal acquisition module malfunctions or the train is in a preset special state.

[0100] In actual use, an emergency module is also set up; the emergency module is connected to the door control module and the instrument display module respectively; during operation, when the signal acquisition module fails or the train is in a preset special state, the emergency module starts to work, generates an emergency signal, and sends an emergency signal to the door control module.

[0101] In this embodiment, the preset special states are: the train has not entered the platform, the dispatch control center cannot give the door opening permission signal, the signal fluctuation causes the signal acquisition module to be unable to obtain the door opening permission signal, and the train is being debugged.

[0102] That is, when the signal acquisition module malfunctions, or when the train is in the aforementioned special state, the train doors can be opened without a door opening permission signal. Therefore, an emergency door opening mode is set up to open the doors via an emergency signal.

[0103] Preferably, the emergency module includes: a judgment submodule and a signal generation submodule;

[0104] The judgment submodule is connected to the door switch signal submodule and the signal generation submodule, respectively;

[0105] The judgment submodule is used to perform multiple judgments based on the door opening and closing parameters and according to the first preset rule to generate the first emergency judgment result.

[0106] The signal generation submodule is used to generate emergency signals based on the first emergency judgment result.

[0107] In practical application, the emergency module is equipped with a judgment submodule and a signal generation submodule. The judgment submodule is connected to the door switch signal submodule and the signal generation submodule. During operation, the judgment submodule reads the door switch parameters from the door switch signal submodule, combines them with the door opening parameters transmitted by the vehicle controller, and performs multiple judgments according to the first preset rule to obtain the first emergency judgment result, which is used to determine the conditions for emergency door opening. The signal generation submodule generates an emergency signal based on the first emergency judgment result.

[0108] In this embodiment, considering that the emergency door opening mode is not the regular door opening mode, certain conditions should be set to limit the generation of the emergency signal. Therefore, a first preset rule is set, and multiple judgment conditions are formulated based on the door opening and closing parameters to obtain multiple judgment results. Finally, a first emergency judgment result is obtained, and an emergency signal is generated based on the first emergency judgment result.

[0109] Preferably, the emergency module further includes: a signal cancellation submodule;

[0110] The signal cancellation submodule is connected to the judgment submodule;

[0111] The judgment submodule is also used to perform multiple judgments based on the door opening and closing parameters and the second preset rules to generate a second emergency judgment result;

[0112] The signal cancellation submodule is used to cancel emergency signals based on the second emergency judgment result.

[0113] In practical application, the emergency module is also equipped with a signal cancellation submodule. The signal cancellation submodule is connected to the judgment submodule. During operation, the judgment submodule reads the door opening parameters from the door opening signal submodule, combines them with the door opening parameters transmitted by the vehicle controller, and performs multiple judgments according to the second preset rule to obtain the second emergency judgment result, which is used to determine the conditions for canceling the emergency signal. The signal cancellation submodule cancels the emergency signal according to the second emergency judgment result.

[0114] In this embodiment, since an emergency door opening mode is adopted, the emergency signal may still exist when the train returns to normal. At this time, the emergency signal will interfere with the normal door opening of the train. The emergency signal should be eliminated so that the train can return to the normal door opening mode.

[0115] It should be noted that the first and second preset rules in this embodiment will be illustrated with examples below, and will not be repeated here.

[0116] like Figure 4 As shown, a dual-end train door opening control method, implemented based on any of the aforementioned dual-end train door opening control systems, is characterized by comprising the following steps:

[0117] S1. Obtain the door opening permission signal;

[0118] S2. Collect door opening parameters;

[0119] S3. Control the opening of the train doors according to the door opening permission signal and door opening parameters.

[0120] In step S1, after the train comes to a complete stop, the dispatch control center sends a door opening permission signal to the train through the signaling device inside the train, and the door control console inside the train receives the door opening permission signal.

[0121] In step S2, the vehicle controller in the column collects the door opening parameters inside the vehicle;

[0122] In step S3, the door control console inside the train controls the opening of the corresponding door based on the door opening permission signal and door opening parameters.

[0123] like Figure 5 As shown, preferably, if obtaining the door opening permission signal fails or the train is in a preset special state, the following steps are included before step S2:

[0124] S11. Obtain emergency signals;

[0125] Step S3 specifically involves controlling the train doors to open based on the emergency signal and door opening parameters.

[0126] Step S11 includes the following steps:

[0127] A1. Obtain door opening / closing parameters;

[0128] A2. Determine whether the train has stopped based on the door opening parameters;

[0129] A3. If so, then determine whether the door switch pressing time is within the range of the preset first time and preset second time based on the door switch parameters;

[0130] A4. If so, determine whether the door switch has been released based on the door switch parameters;

[0131] A5. If so, an emergency signal will be generated.

[0132] In actual use, if the train does not receive the door opening permission signal sent by the dispatch control center, or if the train is in a preset special state, the train will adopt the emergency door opening mode. At this time, before step S2, an emergency signal should also be obtained. In step S3, the train controls the corresponding door to open according to the emergency signal and door opening parameters.

[0133] In step A1, the door control module in the door control console acquires the door opening and closing parameters and sends them to the judgment submodule in the emergency module of the door control console; at the same time, it sends the door opening parameters to the judgment submodule.

[0134] In step A2, the judgment submodule determines whether the train has stopped, i.e., the train speed is zero, based on the door opening parameters; in this embodiment, it determines whether a zero-speed signal exists, and if so, the train stops.

[0135] In step A3, if the train has stopped, the judgment submodule determines whether the door pressing time is within a preset time range based on the door switch parameters. In this embodiment, it determines whether the door switch pressing time is between 200ms (preset first time) and 2S (preset second time). When the door switch pressing time is less than 200ms, the signal generated by the door switch is an interference signal. When the door switch pressing time is greater than 2S, the signal generated by the door switch is a long press signal, generating a door opening enable.

[0136] In step A4, if the door switch is pressed within the specified time range and the door opening enable is already available, then the door switch release status is further used to determine whether the door switch has been released.

[0137] In step A5, if so, the judgment submodule sends the first emergency judgment result to the signal generation submodule, and the signal generation submodule generates an emergency signal based on the first emergency judgment result.

[0138] like Figure 6 As shown, preferably, if the train leaves the preset special state and an emergency signal is present, the following steps are included after step S11 and before step S1:

[0139] S12. Eliminate emergency signals;

[0140] Step S12 includes the following steps:

[0141] B1. The duration of the emergency signal;

[0142] B2. Based on the door opening / closing parameters, determine whether the corresponding door has been opened.

[0143] B3. If not, determine whether the door switch has failed based on the door switch parameters;

[0144] B4. If not, determine whether the duration of the emergency signal exceeds the preset third time.

[0145] B5. If not, determine whether the train's traction speed is greater than zero speed based on the door opening parameters;

[0146] B6. If so, then cancel the emergency signal.

[0147] In actual use, if the train has left the preset special state and the emergency signal still exists, the train should cancel the emergency signal and return to the normal door opening mode; at this time, the emergency signal should be canceled after step S11 and before step S1.

[0148] In step B1, a timing tool is added to the emergency module to obtain the duration of the emergency signal, and the duration of the emergency signal is sent to the judgment submodule.

[0149] In step B2, the judgment submodule determines whether the car door has been opened based on the door opening and closing status;

[0150] In step B3, if the door fails to open, the judgment submodule determines whether the door switch has failed based on the door switch failure status.

[0151] In step B4, if the door switch is not malfunctioning, determine whether the emergency signal has existed for more than 1 minute (preset third time).

[0152] In step B5, if the emergency signal exists for no more than 1 minute, the judgment submodule determines whether the train traction speed is greater than zero speed based on the traction command signal (i.e., the train has not stopped but is in traction operation state).

[0153] In step B6, if the train traction speed is greater than zero speed, the judgment submodule generates a second emergency judgment result and sends the second emergency judgment result to the signal cancellation submodule; the signal cancellation submodule cancels the emergency signal.
