Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The door control method for a rail vehicle provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0033] Figure 1 A schematic flow chart of a door control method for a rail vehicle provided by the present invention is shown in FIG. Figure 1 As shown, the present invention provides a door control method for a rail vehicle, and the method may include the following steps.

[0034] Optionally, the execution entity of the following steps is a door controller.

[0035] S100, executing a first judgment on whether the rail vehicle is preparing to or starting to leave the platform, and if the first judgment obtains an affirmative result, sending a first signal to lock the auxiliary lock.

[0036] Optionally, a basis for obtaining a positive result of the first judgment includes: obtaining a closing signal of the vehicle door.

[0037] Optionally, obtaining the door closing signal is based on triggering of a door fully locked switch.

[0038] S200, obtaining a vehicle speed signal. When it is determined that the vehicle speed is greater than a predetermined threshold, obtaining a status signal of the auxiliary lock. If the status signal indicates that the auxiliary lock is not locked, sending a second signal to lock the auxiliary lock.

[0039] Optionally, the vehicle speed is provided to the door controller via a Train Control and Management System (TCMS).

[0040] Optionally, when the vehicle is about to enter the platform and starts to decelerate, when the vehicle speed is lower than a predetermined speed, the door controller controls the auxiliary lock to unlock in advance.

[0041] Optionally, TCMS provides the platform side information that needs to be unlocked to the door controller. The door controller only unlocks the auxiliary lock on the platform side and does not take any action on the non-platform side.

[0042] Optionally, when the vehicle arrives at the station and stops, the door controller performs door opening and door closing actions on the platform side.

[0043] In this embodiment, when the vehicle leaves the platform and starts to speed up, when the vehicle speed exceeds a certain speed, the door controller performs a second confirmation on the auxiliary lock status. The unlocked auxiliary lock will be locked, and the locked auxiliary lock will not be activated, thereby improving safety.

[0044] Further, based on the above-mentioned embodiment, in another embodiment, this embodiment provides a door control method for a rail vehicle, the method further comprising:

[0045] Confirm that the status signal of the auxiliary lock has failed;

[0046] Execute a second determination of whether a vehicle zero speed signal is obtained;

[0047] If the second determination yields an affirmative result, a third signal for unlocking the auxiliary lock is issued.

[0048] It should be noted that obtaining a vehicle zero speed signal means that the vehicle is stationary or almost stationary.

[0049] Optionally, if the second judgment obtains a negative result, no operation is performed.

[0050] Optionally, confirming the failure to obtain the status signal of the auxiliary lock includes that a vehicle communication failure occurs, and the door controller cannot obtain the status signal of the auxiliary lock. At this time, the operation is performed only by relying on the presence or absence of a vehicle zero speed signal.

[0051] This embodiment realizes automatic control of the auxiliary lock by relying on the vehicle zero speed signal when the vehicle communication fails.

[0052] Further, based on the above-mentioned embodiment, in another embodiment, this embodiment provides a door control method for a rail vehicle, the method further comprising:

[0053] Obtain the status signal of the auxiliary lock and the emergency unlocking signal when the rail vehicle is in an emergency;

[0054] executing a third determination of whether a vehicle zero speed signal is obtained;

[0055] If the third judgment obtains a positive result, a fourth signal is issued to unlock the auxiliary lock; if the third judgment obtains a negative result and the auxiliary lock is not locked, a fifth signal is issued to instruct the unlocking motor of the vehicle door to enter a locked state, so that the unlocking motor continues to output a blocking torque in the opposite direction to the door opening torque.

[0056] Optionally, if the third judgment obtains a negative result and the auxiliary lock is locked, no operation is performed.

[0057] Optionally, if the door controller obtains the vehicle zero speed signal and emergency unlocking signal, the door controller controls the auxiliary lock solenoid valve to cut off power, the auxiliary lock is unlocked, the door is unlocked and opened by the emergency unlocking wire rope, and the door can be opened and closed manually.

[0058] Optionally, if the door controller fails to obtain the vehicle zero speed signal and obtains the emergency unlocking signal at the same time, if the auxiliary lock is in the pressed state, the door cannot be opened and there will be no action; if the auxiliary lock is in the unlocked state and the door is unlocked, the door controller will control the unlocking motor to block.

[0059] In an emergency scenario, this embodiment determines whether the vehicle has stopped. If it is determined that the vehicle has not stopped, the blocking unlocking motor outputs a blocking torque to prevent the door from opening and prevent people from being thrown out. If it is determined that the vehicle has stopped, the auxiliary lock is unlocked to achieve automatic control of the vehicle's doors in an emergency.

[0060] Further, based on the above-mentioned embodiment, in another embodiment, this embodiment provides a door control method for a rail vehicle, the method further comprising:

[0061] An isolation signal indicating that the vehicle door has a closing fault is obtained;

[0062] A sixth signal is issued to lock the auxiliary lock.

[0063] Optionally, the door closing failure includes: a fully closed switch of the door and / or a fully locked switch of the door cannot be triggered.

[0064] Optionally, the isolation signal is obtained by the door controller after the isolation lock is locked.

[0065] This embodiment enables automatic control of the auxiliary lock in the event of a door failure.
