[0033] The flipping pedal 1, flipping mechanism 2, flipping motor 3, flipping motor controller 4, telescopic in-position detection switch 5, and door operator controller 6 are multiple groups, and the number is the same as the number of safety doors on one side of the rail transit vehicle. The platform clearance of each safety door.

[0034] The present invention also includes an emergency operation switch 8 which is connected with the flipping motor 3, and in an emergency state, the operation of the flipping motor 3 is manually controlled.

[0035] The door operator controller 6 is also connected with a manual unlocking switch 9 and an isolating switch 10, and the isolating switch 10 is used to isolate the high-voltage and low-voltage sides of the platform gap compensation system to improve the safety and reliability of the system.

[0036] The turning mechanism 2 is a multi-link hinge mechanism. The turning pedal 1 is movably installed at the bottom of the outer side of the safety door sill 13 through a multi-link hinge mechanism. The turning pedal 1 is flush with the safety door sill 13 after being unfolded. The dead center of the hinge mechanism ensures that the movable flipping pedal 1 will not fall due to power failure or external force. The flipping pedal 1 is also connected with a bypass switch 11 and a limit switch 12.

[0037] Such as image 3 As shown, the door operator controller 6 is provided with five input ports and two output ports. The five input ports are the signal of turning pedal in position, the signal of turning pedal received, the signal of turning pedal bypass, the signal of turning pedal manual unlocking and Flip pedal fault feedback signal, flip pedal extension signal, flip pedal received position signal is directly connected to telescopic in-position detection switch 5, used to detect the current flipping state; flip pedal bypass signal and a pair of normally open bypass switch 11 The contacts are connected to monitor whether the current pedal is in an obstacle state. The manual unlocking signal of the flap is connected with the manual unlocking switch 9 to detect whether the flap is in the manual unlocking state; the pedal fault feedback signal is controlled by the intermediate relay and the flap motor The two output ports of the door machine controller 6 are the unfolding or retracting signal of the flipping pedal, the flipping pedal enable signal, and the flipping pedal enable signal. It is used to control and turn the pedal into working state to improve safety performance.

[0038] The two input ports of the flipping motor controller 4 are the flipping pedal enable signal and the flipping pedal expansion or retracting signal, which are connected to the door machine controller 6 to receive, and one output signal is the electric flipping fault signal, which passes through the intermediate relay. Connect with door machine controller 6.

[0039] The control method based on the above-mentioned urban rail transit platform gap automatic compensation mechanism control system includes the following steps:

[0040] Step (1): When the rail transit vehicle arrives at the station, the door operator controller 6 of each safety door receives the door opening signal, and the door operator controller 6 outputs the unfolding and turning pedal signal to the flap motor controller 4;

[0041] Step (2), the flipping motor controller 4 controls the flipping motor 3 to rotate, and the flipping motor 3 drives the flipping mechanism 2 to flip to realize the flipping pedal 1 is extended upward;

[0042] Step (3), after the delay, the door machine controller 6 controls the opening of the safety door, and at the same time detects the extension in position signal sent by the telescopic in-position detection switch 5, the door machine controller 6 outputs the unfolding and flipping pedal signal. After the delay, if not received If the position signal is received, it is judged as a fault, and an audible and visual alarm is output; if the extension signal is received, the rollover pedal 1 is normally deployed;

[0043] Step (4), before the rail transit vehicle leaves the station, the door operator controller 6 of the safety door receives the door closing signal, closes and locks the safety door, and outputs the retractable pedal signal to the flap motor controller 4;

[0044] Step (5), the flipping motor controller 4 controls the flipping motor 3 to rotate, and the flipping motor 3 drives the flipping mechanism 2 to flip to realize the flipping pedal 1 is retracted downward;

[0045] Step (6): After the delay, the door machine controller 6 detects the received bit signal sent by the telescopic in-position detection switch 5. If the received bit signal is not received, it is judged as a failure and an audible and visual alarm is output; if the received bit signal is received , The folding pedal 1 is normal;

[0046] Step (7), the limit switch 12 is triggered after the flip pedal 1 is retracted, and the contact of the limit switch 12 is connected to the loop of the safety door system. When all the limit switches on the pedal 1 on one side of the rail transit vehicle are flipped When the contacts of (received position) are closed, the rail transit vehicle exits the station safely.

[0047] Among them, the delay time after the delay of steps (3) and (6) is 3S, and the door machine controller 6 outputs the unfolding and flipping pedal signal. After the waiting delay, the waiting delay time is 5S, and the time is adjustable.

[0048] Wherein, in step (2), the flipping motor 3 drives the flipping mechanism 2 to flip to realize the upward deployment of the flipping pedal 1 and a method for preventing the extrusion of the flipping pedal 1 is provided, including the following steps:

[0049] (1) During the extension process of the turning pedal 1, the door operator controller 6 detects whether there is an obstacle. If there is an obstacle, stop the extension movement and fold it; if there is no obstacle, the turning pedal 1 is normally deployed;

[0050] (2) When the flip pedal 1 is stowed and held for 1 second, the time can be adjusted. The flip pedal 1 will continue to perform the upward unfolding process. If there are still obstacles, the flap motor 3 will stop rotating, and the flip pedal 1 will stay at the obstacle. The maximum unfolding position of, output acousto-optic alarm; if the obstacle is eliminated, the flip pedal 1 will unfold normally.

[0051] Wherein, in step (5), the flipping motor controller 4 controls the rotation of the flipping motor 3, and the flipping motor 3 drives the flipping mechanism 2 to flip to realize the flipping pedal 1 is retracted downwardly, and the flipping pedal 1 is also provided to retract the anti-crush The pressure method includes the following steps,

[0052] (1) During the retracting process of the turning pedal 1, the door machine controller 6 detects whether there is an obstacle. If there is an obstacle, stop the retraction movement and extend it; if there is no obstacle, the turning pedal 1 is normally stowed;

[0053] (2) When the flip pedal 1 is extended and held for 1 second, the time is adjustable. The flip pedal 1 continues to perform the downward retracting process. If there is still an obstacle, the flip motor 3 stops rotating, and the flip pedal 1 stays When the obstacle is encountered, the maximum stowed position will output sound and light alarm; if the obstacle is eliminated, the flip pedal 1 will be retracted normally.
