As can be seen in the figure, the drive unit comprises a drive drum device D1, a wire rope traction device; the driving reel device D1 includes a motor reducer, a reel shaft, a reel, and a reel bearing seat (for simplification, the driving reel device D1 is simplified in the drawing, and the motor reducer, the reel shaft, the reel, and the reel bearing seat are not explicitly shown), and the related assembling relationships are as follows: the motor speed reducer is fixedly arranged on the ground on one side, far away from the lane, of the parking space pit A4 in the vehicle length direction, and the axis of the output component is vertical to the vehicle length direction of the parking space pit A4; the number of the winding drums is two, and the two winding drums are tightly installed on a winding drum shaft; the winding drum shaft is tightly installed on the ground of one side, far away from the lane, of the parking space pit A4 in the vehicle length direction through the winding drum bearing seat, the winding drum shaft is tightly connected with the output part of the motor speed reducer, the axis of the winding drum shaft is overlapped with the axis of the output part of the motor speed reducer, and the effective working intervals of the two winding drums are opposite to the side line of the parking space pit A4 in the vehicle width direction.

The process of transitioning the state of fig. 2 to the state of fig. 1 is described as follows:

the first step is as follows: and the user operates the human-computer interface unit to give an instruction for lifting the parking equipment.

The second step is that: the equipment control unit receives the instruction, namely sends a driving signal of inward retraction to the anti-falling device E1 of the safety unit, so that the supporting part of the anti-falling device E1 is in an inward retraction state; meanwhile, the equipment control unit sends a signal to related components of the power supply system to enable a motor reducer of the driving unit to operate in a forward direction, the motor reducer rotates to drive a winding drum of the driving unit to rotate in a forward direction (clockwise direction shown in the figure), and the winding drum rotates in the forward direction to wind a steel wire rope D4 of a steel wire rope traction device, so that a bottom layer vehicle carrying plate B1 of the bottom layer vehicle carrying plate unit vertically rises along a stable guide upright post B2 of the bottom layer vehicle carrying plate unit under the traction of the steel wire rope D4.

The third step: the bottom layer vehicle carrying board B1 rises to the right, and the rising right detection device of the safety unit is triggered to send a right signal.

Fourthly, the equipment control unit receives the in-place signal, namely sends a driving signal for resetting the support to the anti-falling device E1 of the safety unit, so that the support part of the anti-falling device E1 returns to the state of the resetting support; meanwhile, the equipment control unit sends a signal for stopping the motor reducer of the driving unit to relevant components of the power supply system, so that the motor reducer stops running, and the bottom layer vehicle carrying board B1 stops rising.

The state shown in fig. 2 is now changed to the state shown in fig. 1.

The process of illustrating the state transition of fig. 1 to the state of fig. 2 is described as follows:

the state shown in fig. 1 is a normal state of the parking equipment and the bottom layer vehicle carrying board B1 is located at the highest position of the parking space pit a 4; the parking equipment can only execute descending action, and the control flow and relevant logic of the equipment control unit are as follows:

The second step is that: the equipment control unit receives the instruction, namely sends a driving signal of inward retraction to the anti-falling device E1 of the safety unit, so that the supporting part of the anti-falling device E1 is in an inward retraction state; meanwhile, the equipment control unit sends a signal to related components of the power supply system to enable the motor reducer of the driving unit to run reversely, the motor reducer rotates to drive the winding drum of the driving unit to rotate reversely (anticlockwise in the drawing), and the winding drum rotates reversely to release the steel wire rope D4 of the steel wire rope traction device, so that the bottom layer vehicle carrying plate B1 of the bottom layer vehicle carrying plate unit vertically descends along the stable guide upright post B2 of the bottom layer vehicle carrying plate unit under the traction of the steel wire rope D4.

The third step: the bottom layer vehicle carrying board B1 descends to the right position, and the tension sensor of the safety unit is triggered to send a right position signal with zero load.

Fourthly, the equipment control unit receives the in-place signal, namely sends a driving signal for resetting the support to the anti-falling device E1 of the safety unit, so that the support part of the anti-falling device E1 returns to the state of the resetting support; meanwhile, the equipment control unit sends a signal for stopping the motor reducer of the driving unit to relevant components of the power supply system, so that the motor reducer stops running, and the bottom layer vehicle carrying board B1 stops descending.

The state shown in fig. 1 is now changed to the state shown in fig. 2.
