Step 2: When the central controller detects that a bicycle is stored in the parking space closest to the borrowing column, the central central controller does not act, and the bicycle needs to be manually taken out through the borrowing gap; when the central controller detects that the bicycle is closest to the borrowing column When there is no bicycle parked in the parking space, the central controller drives the third motor corresponding to the bicycle closest to the borrowed column to act, the third motor rotates in the reverse direction, and the corresponding bump moves away from the conveyor belt. The wheel and the bump are gradually disengaged. When the central controller detects that the second pressure sensor on the bump becomes smaller to a predetermined value, the central controller determines that the bicycle falls on the conveyor belt; the central controller drives the second motor to rotate to convey the The belt conveys the bicycle to the direction of the borrowing column, and at the same time, the faucet of the bicycle assists the bicycle to move toward the direction of the borrowing column;

During the movement of the bicycle toward the borrowing column, when the first signal transmitter in the sleeve and the first signal receiver on the end of the guide rod close to one end of the borrowing column face up and down, the first signal receiver receives to the in-position signal from the first signal transmitter, and the first signal transmitter sends the in-position signal to the central controller, and the central controller controls the second motor to stop rotating, and then manually takes out the bicycle from the self-borrowing gap;

Step 3: After the predetermined time, the central controller controls the linear motor in the borrowed column to reverse, and the insertion rod on the borrowed column extends toward the return column, and the inserted rod on the borrowed column is inserted into the guide rod. When the rod end of the plunger in the column touches the third pressure sensor at the bottom of the slot, the real-time pressure information sent by the third pressure sensor to the central controller changes, and when the pressure sent by the third pressure sensor reaches a predetermined value , the central controller determines that the insertion rod is in place, and drives the linear motor in the borrowing column to stop rotating; at this point, the borrowing process ends.

step 1, a car borrowing card is used for swiping a card in a car returning and card swiping area, and a car returning signal receiver receives a signal transmitted by a car borrowing and returning signal transmitter in the car borrowing card and sends the signal to a central controller; the central controller judges whether a vehicle returning mode exists or not according to the signals transmitted by the first pressure sensor, if no vehicle returning mode exists, the central controller does not stop acting, if no vehicle returning mode exists, the central controller drives the linear motor in the vehicle returning column to rotate forwardly according to the received signals from the vehicle returning signal receiver, the linear motor in the vehicle returning column is started, the inserting rod on the vehicle returning column contracts inwardly of the vehicle returning column, the inserting rod on the vehicle returning column is separated from the guide rod and exposes a vehicle returning gap for placing a vehicle, and when the linear motor in the vehicle returning column runs for a preset time, the central controller drives the linear motor in the vehicle returning column to stop running;

step 2, manually sleeving a sleeve of the bicycle on the guide rod through a returning gap, and simultaneously placing a rear wheel of the bicycle on the conveying belt; when a first signal transmitter on the sleeve is opposite to a first signal receiver on the end of the guide rod up and down, the first signal receiver receives an in-place signal transmitted from the first transmitter, the first signal receiver transmits the in-place signal to the central controller, the central controller drives the second motor to rotate forwards and the first motor to rotate forwards, the conveying belt moves towards the direction of the car borrowing column, meanwhile, the sliding block moves towards the direction of the car borrowing column, and the driving rod drives the sleeve to move towards the direction of the car borrowing column, so that the car head and the car tail synchronously move towards the direction of the car borrowing column;

step 3, the first pressure sensor on each parking space transmits the pressure information to the central controller in real time, and the central controller judges whether a bicycle is parked on the parking space according to the received pressure information; the central controller controls the bicycle to move to an empty parking space closest to the bicycle borrowing column, and drives the first motor and the second motor to stop rotating after the central controller monitors that the pressure of the parking space reaches a preset value;

step 1, swiping a card in a card swiping area of a car borrower by using a car borrower card, receiving a signal transmitted by a borrowing and returning signal transmitter in the car borrower card by a car borrower signal receiver, and transmitting the signal to a central controller; the central controller judges whether a bicycle can be borrowed according to the pressure information transmitted by the first pressure sensor, if no bicycle can be borrowed, the central controller does not act any more, if the bicycle can be borrowed, the central controller drives the linear motor in the bicycle borrowing column to rotate forwards according to the received signal from the bicycle borrowing signal receiver, the inserted rod on the bicycle borrowing column contracts towards the inside of the bicycle borrowing column, the inserted rod on the bicycle borrowing column is separated from the guide rod and exposes a bicycle borrowing gap for taking the bicycle, and when the linear motor in the bicycle borrowing column runs for a preset time, the central controller drives the linear motor in the bicycle borrowing column to stop running;

step 2, when the central controller detects that the bicycle is stored in the parking space closest to the bicycle borrowing column, the central controller does not act and needs to manually take out the bicycle through the bicycle borrowing space; when the central controller detects that no bicycle is parked at the parking place closest to the bicycle borrowing column, the central controller drives a third motor corresponding to the bicycle closest to the bicycle borrowing column to act, the third motor rotates reversely, the corresponding bump moves towards the direction far away from the conveying belt, the rear wheel of the bicycle is gradually separated from the bump, and when the central controller detects that a second pressure sensor on the bump is reduced to a preset value, the central controller judges that the bicycle falls onto the conveying belt; the central controller drives the second motor to rotate, the conveying belt conveys the bicycle towards the bicycle borrowing column, and meanwhile, the handle of the bicycle is held by hands to assist the bicycle to move towards the bicycle borrowing column;

in the process that the bicycle moves towards the direction of the bicycle borrowing column, when a first signal transmitter in the sleeve and a first signal receiver on the end head of the guide rod close to one end of the bicycle borrowing column face to each other up and down, the first signal receiver receives a target-in-place signal from the first signal transmitter, the first signal transmitter transmits the target-in-place signal to the central controller, the central controller controls the second motor to stop rotating, and then the bicycle is manually taken out from a bicycle borrowing gap;

step 3, after the preset time, the central controller controls the linear motor in the car borrowing column to rotate reversely, the inserted link on the car borrowing column extends towards the direction of returning the car to the car, the inserted link on the car borrowing column is inserted into the guide rod, when the rod end of the inserted link in the car borrowing column touches the third pressure sensor at the bottom of the slot, the real-time pressure information transmitted to the central controller by the third pressure sensor changes, and when the pressure transmitted by the third pressure sensor reaches the preset value, the central controller judges that the inserted link is in place and drives the linear motor in the car borrowing column to stop rotating; the vehicle borrowing process is now complete.
