Description

Parking control method of parking system

The present invention relates to a parking system, and more particularly, to a parking control method of a parking system to perform a normal operation even if a position error occurs.

In general, the parking system is as shown in the schematic configuration of FIG.

First, in the case of wearing the vehicle, as shown in FIG. 2, when the vehicle is positioned on the lift 101 through an entrance and exit, the lift 101 has an empty space by the operation of the lifting driving unit 110 receiving the wearing command. Will move to that location.

Thereafter, when the lift 101 reaches the corresponding position, the tray 102 moves to the center and intersects with the lift 101 so that the vehicle is moved to the tray 102.

After that, the tray 102 moves to the empty space to put the car on, and the lift 101 moves to the initial position.

In addition, as shown in FIG. 3, when the vehicle is shipped, the lift 101 is moved to the corresponding position by the operation of the lifting driver 110 receiving the release command, and the lift 101 reaches the corresponding position. The vehicle is loaded on the tray 102 and moved to the center.

Thereafter, as the lift 101 and the tray 102 cross each other, the vehicle is moved on the lift 101.

After that, when the tray 102 moves to the empty space and the lift 101 moves to the initial position, the tray 102 changes the direction of the vehicle, if necessary, to be released to the outside.

Operation for entering and exiting the vehicle as described above is performed by a general parking control device as shown in the block diagram of FIG. 4.

That is, when the lift 101 is to be moved to an arbitrary position for entering and leaving the vehicle, the controller 130 transmits a motor driving command to the motor driving unit 120.

At this time, the motor driving unit 120 outputs a motor driving signal corresponding to the motor driving command to the lifting driving unit 110 to drive the motor 112.

Accordingly, the sheave 111 is rotated in the corresponding direction by the motor 112 to move the lift 101 to an arbitrary position, thereby making the vehicle in and out.

In this case, the controller 130 checks the floor height through a position detector (not shown) as the lift 101 moves, and requests the current position of the lift 101 from the motor driving unit 120 to compare with the floor height. The lift 101 is controlled to move to the floor.

The prior art is performed through the same process as the signal flow diagram of FIG. 5.

First, in order to move the lift 101 to a predetermined position, the controller 130 transmits the position data to be moved from the control unit 130 to the motor driving unit 120 and transmits a command for the movement. The motor 112 is driven to move the lift 101 to a desired position.

For example, if the lift 101 is on the first floor and the vehicle is to be parked on the third floor, it is assumed that the motor driver 120 has position data regarding the first floor. The position data about the floor is transmitted and a command to move the lift 101 is transmitted, and the motor driver 120 drives the motor 112 to move the lift 101.

At this time, the control unit 130 checks the floor height through a position detector (not shown) as the lift 101 moves. If the second floor reaches the second floor, the control unit 130 sends the motor driving unit 12 to the motor driving unit 12. The current position of the lift 101 is required.

Accordingly, the controller 130 compares the height data measured by the position detector (not shown) with the position data transmitted from the motor driver 120 to calculate the difference value and to compare the difference value with the tolerance (tol). do.

Therefore, if the difference value is within the tolerance (tol), it is regarded as normal and continues to move while checking whether the lift 101 is to be stopped, and when the lift 101 reaches the third floor, the elevation data and the lift are above. After performing the operation of comparing the current position data of 101, the lift 101 is stopped when it is within the tolerance.

If the difference is greater than the tolerance (tol), the controller 130 determines that an error has occurred, transmits a stop command to the motor driver 120, outputs an error code to the monitor or display, and processes the error again. The system will start up.

However, this conventional technology unconditionally stops the operation of the system when the motor drive command or position data is broken by noise, or when an error occurs in the program itself or due to a mechanical effect. There is a problem that not only satisfies users, but also wastes time.

Therefore, in order to improve the conventional problem, when the location is checked during the loading and unloading operation of the vehicle, even if an error occurs, the system automatically recovers the error without stopping the operation of the system so that the vehicle can be normally driven to a desired position. It is an object of the present invention to provide a parking control method of the inventive parking system to improve the stability and efficiency of operation.

In order to achieve the above object, the present invention compares a current position value and a previous position value during a lift movement, calculates an actual movement distance, and compares whether the actual movement distance is greater than the constant speed traveling value, and wherein the actual movement distance is If it is greater than the constant speed value, it is regarded as an error and transmits a low-speed driving command, detects the value of the floor close to the moving direction, corrects the position data of the current floor, and operates the lift at a constant speed with the corrected position data. If the actual moving distance is within the constant traveling value, the step of detecting the current floor height value and the position value, and comparing the current floor height value and the current position value in the above to compare whether the difference is within the tolerance (tol) And stopping the movement of the lift if the difference value is within an allowable error.

Hereinafter, the present invention will be described in detail with reference to the drawings.

The apparatus for an embodiment of the present invention is the same as the block diagram of FIG.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

In the present invention, it is assumed that the lift 101 is on the first floor and the vehicle is to be parked on the third floor, and the motor driver 120 has the position data regarding the first floor.

First, the control unit 130 transmits the position data about the third floor to the motor drive unit 120 and sends a command to move the lift 101 to the third floor, the motor drive unit 120 of the lifting drive unit 110 By driving the motor 112, the lift 101 is moved to the third floor.

At this time, a timer is set in driving the motor 112 to move the lift 101 to a predetermined position, and the program is executed by the set timer every time.

Here, when the timer value is '0.001 seconds' and the maximum speed of the lift 101 is '60M / min', the maximum distance that the lift 101 can move for '0.001 seconds' is '1 mm', Let's call it constant speed.

Therefore, after the timer time has passed '0.001 second', the controller 130 requests the current position of the lift 101 from the motor driving unit 120 and calculates the actual moving distance by comparing the current position value with the previous position value. Then, it compares whether the actual travel distance is larger than the constant speed travel value (= 1 mm).

At this time, if the actual moving distance is larger than the constant speed traveling value (= 1mm), the controller 130 considers it to be an error and transmits a low-speed driving command to the motor driving unit 120 and moves to a floor close to the moving direction (for example, the rising direction). The position detector (not shown) is checked to detect the corresponding floor height value.

Accordingly, upon detecting the corresponding floor height value, the controller 130 increases the value of the current floor by '1', simultaneously corrects the position with the floor height value, and transmits the corrected position data to the motor driver 120 again. Move the lift 101 at a normal speed.

When the '0.001 second' has elapsed while the lift 101 is moving, if the actual moving distance is within the constant traveling value (= 1 mm), it is determined to be normal and the position detector (not shown) is checked to determine the corresponding floor height value. Will be measured.

In this case, when the corresponding height value is measured, the controller 130 increases the value of the current floor by '1' and requests the current position value from the motor driver 120 to compare the height data with the current position data.

Accordingly, when the difference between the height data and the current position data value is within the tolerance (tol), the control unit 130 transmits a stop command to the motor driving unit 120 to stop the movement of the lift 101.

If the difference is more than the tolerance (tol), the above operation is repeated until the lift 101 reaches the desired position.

Therefore, the vehicle is entered and exited by moving the lift 101 to a desired position by performing the above operation.

As described in detail above, the present invention provides the safety and safety of the parking operation by moving the position data to a desired position without stopping the operation of the system even if a position error occurs while moving the lift for entering and leaving the vehicle. By improving efficiency, there is an effect of providing time waste and user satisfaction.
