The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the present application provides a vehicle door control system, as shown in fig. 1, which is applied to a railway vehicle, where the railway vehicle includes multiple carriages, each carriage includes a first vehicle door and a second vehicle door distributed on two sides of the carriage, and the vehicle door control system includes: a controller 30, a plurality of first gate control units 10, a plurality of second gate control units 20, a plurality of first detection means and a plurality of second detection means; wherein the content of the first and second substances,
one of the first detecting devices is disposed at (near/below) an outer side of one of the first doors, and is configured to send a first signal to the controller 30 and the first door control unit 10 corresponding to the first detecting device when a station is disposed at the outer side of the first door;
one of the second detection devices is disposed outside (near/below) one of the second doors, and is configured to send a second signal to the controller 30 and a second door control unit 20 corresponding to the second detection device when a station is disposed outside the second door;
the controller 30 is configured to determine the station position according to all the received first signals or all the received second signals, and send a first enable signal to the first gate control unit 10 or send a second enable signal to the second gate control unit 20 according to the station position;
the first door control unit 10 is configured to control a first door corresponding to the first door control unit 10 to open or close according to a first door control signal when receiving the first door control signal, the first signal and a first enable signal;
the second gate control unit 20 is configured to control, when receiving a second gate control signal, a second signal, and a second enable signal, a second door corresponding to the second gate control unit 20 to open or close according to the second gate control signal.
In fig. 1, VCC represents an operating power supply of the vehicle door control system. Reference numeral 11 denotes that the first detection means is connected to the control signal of the first door control unit in the form of a first relay contact, and specifically, when the first detection means sends a first signal, the first relay contact 11 is closed, and the first signal is transmitted to the controller 30. Similarly, reference numeral 21 denotes that the second detection device is connected to the control signal of the second gate control unit in a manner of a second relay contact, and specifically, when the first detection device sends out the second signal, the second relay contact 21 is closed, and the second signal is transmitted to the controller 30.
In the present embodiment, a first door corresponds to a first detecting device and a first door control unit 10, and a second door corresponds to a second detecting device and a second door control unit 20.
The first and second detection devices may be respectively disposed at positions outside (near/below) the first and second doors, where the platform can be detected, the first and second doors may respectively refer to left and right doors of the rail vehicle, and each car may simultaneously have a plurality of first doors and a plurality of second doors, each of the first doors corresponds to one of the first detection devices, and each of the second doors corresponds to one of the second detection devices.
When the first detecting device detects the station, it sends a first signal to the controller 30 and the corresponding first door control unit 10 to indicate that the first door has the station outside, and the door can be opened. Similarly, when the second detecting device detects the landing, it sends a second signal to the controller 30 and the corresponding second door control unit 20 to indicate that the second door has the landing outside, and the door can be opened.
The first door control signal is a door opening signal or a door closing signal, and similarly, the second door control signal is a door opening signal or a door closing signal. When the first door control unit 10 corresponding to a certain first door receives the first signal, the first enable signal and the first door control signal at the same time, the corresponding first door is controlled to open, any one of the first door control signal, the first signal and the first enable signal is lost, and the first door control unit controls the corresponding first door to automatically close.

In addition, it should be noted that since the platform can be located on only one side of the rail vehicle, the first enable signal and the second enable signal cannot be triggered simultaneously, and if the controller simultaneously sends the first enable signal to the first gate control unit and the second enable signal to the second gate control unit, it is considered that a fault occurs, and the crew member can be reminded to check in a manner of sending an alarm.
Alternatively, the first gate control signal and the second gate control signal may be generated by the first gate control module 41 and the second gate control module 42, respectively.
Namely, the vehicle door control system further includes: a first door control module 41 and a second door control module 42; wherein the content of the first and second substances,
the first gate control module 41 is configured to send a first gate control signal to the first gate control unit when triggered;
the second gate control module 42 is configured to send a second gate control signal to the second gate control unit when triggered.
In addition to the above embodiments, in an embodiment of the present application, the first detection device is disposed at an outer side (near/below) of the first door, a detection surface of the first detection device faces a side away from the second door, and the first detection device is specifically configured to detect an obstacle distance in a direction of the first detection device away from the second door, and send a first signal to the controller 30 and the first door control unit 10 corresponding to the first detection device when the obstacle distance is smaller than a first preset value;
the second detecting device is disposed at an outer side (near/below) of a second vehicle door, a detection surface of the second detecting device faces a side away from the first vehicle door, and the second detecting device is specifically configured to detect an obstacle distance of the second detecting device in a direction away from the first vehicle door, and send a second signal to the controller 30 and a second door control unit 20 corresponding to the second detecting device when the obstacle distance is smaller than a first preset value.
Because the platform is generally positioned below the outer side of the vehicle door, the first detection device is arranged right below the first vehicle door, and the second detection device is arranged right below the second vehicle door, so that the detection precision of the platform is improved, and the interference of other objects to the platform detection process is avoided.
Optionally, the first detection device and the second detection device are both distance detection sensors.
And the distance detection sensor can be selected from an ultrasonic ranging sensor, a laser ranging sensor, an infrared ranging sensor, a radar ranging sensor and the like.
Based on the above embodiments, one embodiment of the present application provides a specific process for the controller 30 to determine the position of the station according to all the received first signals and all the received second signals, including:
when the number of the first signals sent by the first detection device with continuous positions exceeds a first preset number and the number of the received second signals is less than a second preset number, determining that the platform is positioned at one side of the first door;
when the number of the second signals sent by the second detection device with continuous received positions exceeds a first preset number and the number of the received first signals is less than a second preset number, determining that the platform is positioned at one side of the second door;
when the first signals sent by the first detection devices with continuous positions exist, the middle is invalid (namely the first detection device at the middle position does not send the first signals), and the other stations are valid (namely the first detection devices at the two side positions send the first signals), the first detection device at the middle is judged to be in failure;
when the second signal transmitted by the second detection device with continuous positions exists in the middle, the station is invalid (namely the second detection device at the middle position does not transmit the second signal), and the other stations are valid (namely the second detection devices at the two side positions transmit the second signal), and the second detection device at the middle of the transmission is judged to be in fault.
When the number of the received second signals sent by the second detection device exceeds a first preset number, if the number of the first signals sent by the first detection device is larger than zero and smaller than a second preset number, judging that the first detection device sending the first signals breaks down;
when the number of the received first signals sent by the first detection device exceeds a first preset number, if the number of the second signals sent by the second detection device is larger than zero and smaller than a second preset number, judging that the second detection device sending the second signals has a fault;
when the number of the received first signals sent by the first detection device exceeds a first preset number and the number of the received second signals sent by the second detection device also exceeds the first preset number, the first detection device sending the first signals is judged to be in fault or the second detection device sending the second signals is judged to be in fault.
And when the number of the received first signals sent by the first detection device exceeds a second preset number and the number of the received second signals sent by the second detection device also exceeds the second preset number, judging that the first detection device sending the first signals fails or the second detection device sending the second signals fails.
In this embodiment, the first detecting devices with continuous positions refer to that the first doors arranged by the first detecting devices are adjacent, for example, a train of railway vehicles comprises carriages numbered 1, 2 and 3 … …, each carriage comprises two first doors and two second doors, then the four first doors and the four second doors of the carriage No. 1 and the carriage No. 2 are numbered A, B, C and D in sequence, and then the A, B, C, D first detecting device or the second detecting device corresponding to the four first doors or the four second doors is referred to as the first detecting device or the second detecting device with continuous positions.
The values of the first preset quantity and the second preset quantity can be determined according to actual conditions, and in general, the value of the first preset quantity is larger than the value of the second preset quantity.
Optionally, the fault alarm is a buzzer sound and/or a warning light.
Accordingly, when the number of the first signals transmitted by the first detection device having consecutive receiving positions exceeds a first preset number and the number of the received second signals is greater than zero and less than a second preset number, it may be determined that a misjudgment has occurred in the second detection device transmitting the second signals, where the misjudgment may be caused by the presence of an environmental obstacle or a failure of the second detection device itself.
Similarly, when the number of the second signals transmitted by the second detection devices with consecutive receiving positions exceeds a first preset number and the number of the received first signals is greater than zero and less than the first preset number, it may be considered that the first detection device transmitting the first signal has a misjudgment, which may be caused by the presence of an environmental obstacle or a fault of the first detection device itself.
Therefore, optionally, the controller 30 is further configured to determine that the first detection device sending the first signal is faulty when the number of the second signals sent by the second detection devices with consecutive receiving positions exceeds a first preset number and the number of the received first signals is greater than zero and less than a second preset number, and prompt the worker to repair the first detection device that may be faulty.
The controller 30 is further configured to determine that the second detection device sending the second signal fails when the number of the first signals sent by the first detection device with consecutive receiving positions exceeds a first preset number and the number of the received second signals is greater than zero and smaller than a second preset number, and prompt the worker to overhaul the second detection device that may fail by sending corresponding second detection device failure information.
The controller 30 is further configured to send a failure alarm when the number of the received first signals and the number of the received second signals both exceed a first preset number, or the number of the received first signals and the number of the received second signals both exceed a second preset number, and determine that the first detection device that sends the first signal has a failure or the second detection device that sends the second signal has a failure.
