Description

SYSTEM AND METHOD FOR INCOMING AND OUTGOING VEHICLES IN PARKING FACILITIES

TECHNICAL FIELD The present invention generally relates to parking facilities, and more particularly to a system and a method for parking vehicles in a parking facility by detenmning locations for accommodating the vehicles on the basis of an entrance/exit frequency of the vehicles.

BACKGROUND ART Generally, an elevator-type parking facility is established on a ground. The elevator-type parking facility includes pallets for loading vehicles, lifters for moving the pallets, parking spaces for accommodating the vehicles, a manipulation module and control modules for controlling the operations of the elevator-type parking facility in an entrance-level floor. Hereinafter, a conventional elevator-type parking facility will be described in view of Figs. 1 to 3. Figs. 1 and 2 illustrate front and side views of a parking tower in the conventional elevator-type parking facility. As shown in the figures, the parking tower 100 includes a multiplicity of parking spaces 102, a hoist way 104, a plurality of pallets 106 and a multiplicity of lifters 108. Fig. 3 is a schematic diagram illustrating a vehicle entrance/exit system in the elevator-type parking facility. As illustrated in Fig. 3, the vehicle entrance/exit system of the elevator-type parking facility includes the parking tower 100, the manipulation module 200 and the control module 300. The control module 300 is connected to a driving motor 110 of the parking tower 100. A motor sensor (not shown) is installed in the motor 110 through a communication line LI 1. Floor sensors (not shown) are installed on each floor of the parking tower 100 through a communication line L12, while an entrance/exit station is placed at an entrance-level floor of the parking tower 100 through a communication line LI 3. Also, the control module 300 is connected to the manipulation module 200 through a communication line L14. The manipulation module 200 transmits vehicle entrance/exit instructions, which are inputted by the drivers of the vehicles or an operator of the parking facility, to the control module 300 through the communication line L14. The manipulation module 200 also receives data associated with an operation status of the parking tower 100, which is transmitted from the control module 300, and displays the operation status of the parking tower 100. The control module 300 controls entrance/exit operations of the vehicles on the basis of data collected from each sensor according to the vehicle entrance/exit instructions, which are inputted from the manipulation module 200. Fig. 4 is a block diagram showing the manipulation module 200 and the control module 300 of the conventional elevator-type parking facility. Since the parking tower 100 can be identically configured as illustrated in Figs. 1 and 2, the parking tower 100 is not illustrated in Fig. 4. As shown in Fig. 4, the manipulation module 200 includes a manipulation unit 202 and a vehicle number input unit 210. The manipulation unit 202 includes a switching unit 204, a display unit 206 and a lamp unit 208. The switching unit 204 of the manipulation unit 202 is connected to the control module 300 through the communication line L14. The vehicle entrance/exit instructions, which are inputted from the drivers of the vehicles or the operator of the parking facility, are outputted to the control module 300 through the switching unit 204. The display unit 206 displays a parking status and a vehicle number. The lamp unit 208 indicates a warning condition transmitted from the control module 300 through the communication line L14. The vehicle number input unit 210 outputs a vehicle number, which is inputted from the driver of the vehicle or the operator of the parking facility, to the control module 300. Also, as illustrated in Fig. 4, the control module 300 includes a programmable logic controller (PLC) 304 and an inverter 318. The control module 300 controls the whole operation of the vehicle entrance/exit system of the elevator-type parking facility. The PLC 304 includes a central processing unit (CPU) 306, a memory 308, an input unit 310, an output unit 312 and a communication unit 316. The CPU 306 controls the entrance/exit operations of the vehicles and the memory 308 stores data related to the vehicle numbers and the parking status of the parking tower 100. The input unit 310 receives data from the floor sensors and an entrance/exit station sensor, and further receives the vehicle entrance/exit instructions. The output unit 312 outputs a signal for controlling the driving motor 110 to an inverter 318, and also outputs a signal for controlling the opening and closing operations of a door 112. The communication unit 316 receives the vehicle number outputted from the vehicle number input unit 210. The PLC 304 controls an operation of the driving motor 110 through the inverter 318 on the basis of data collected by the input unit 310 from the floor sensors and the entrance/exit station sensor according to the vehicle entrance/exit instructions inputted from the manipulation module 200. This controls the entrance/exit operations of the vehicles. Fig. 5 is a flow chart showing a conventional vehicle entrance/exit method performed by the elevator-type vehicle entrance/exit system illustrated in Fig. 4. Hereinafter, a vehicle entrance process will be described in view of Fig. 5. First, if the vehicle entrance instruction is received from the switching unit 204 at step S302, the CPU 306 of the control module 300 outputs an opening signal through the communication line LI 3 to open the door 112. This is so that the vehicle can be loaded on the pallet 106 of the parking tower 100. The CPU 306 of the PLC 304 receives a vehicle number outputted from the vehicle number input unit 210 of the manipulation module 200 through the communication unit 316 at step S304. An input of the vehicle number may be implemented by the vehicle driver or the operator of the parking facility. Next, the CPU 306 of the PLC 304 retrieves data associated with the parking spaces 102 inputted to the input unit 310 from the floor sensors of the parking tower 100 for selecting one of empty parking spaces 102, which is nearest from the door 112. Then, a floor of the selected empty parking room is set as a target floor at step S306. The data inputted from the floor sensors represents accommodation conditions of each vehicle, that is, a parking status. The CPU 306 of the PLC 304 outputs data associated with the target floor to the manipulation module 200 through the output unit 312 for displaying information of the target floor on the display unit 206. The CPU 306 of the PLC 304 outputs a driving signal to the driving motor 110 through the inverter 318 for elevating the lifter 108 to the target floor at step S308. The lifter 108 delivers the pallet 106, which loads the vehicle, to the target floor. The CPU 306 of the PLC 304 determines whether the lifter 108 has arrived at the target floor on the basis of data received from the input unit 310 through the communication lines LI 1 and LI 2 at step S310. If the determination result in the step S310 is negative, that is, if the lifter 108 has not arrived at the target floor, the process returns to the step S308, thereby continuously elevating the lifter 108. On the other hand, if the determination result in the step S310 is positive, that is, if the lifter 108 has arrived at the target floor, the process proceeds to the step S312. At step S312, the CPU 306 of the PLC 304 outputs a stop signal to the driving motor 110 through the inverter 318, thereby stopping the movement of the lifter 108 at the target floor. The vehicle loaded on the lifter 108 is accommodated in the parking space 102 of the target floor by operating the lifter 108 under the control of the CPU 306 of the PLC 304 at step S314. Since the process for accommodating the vehicle in the parking space is well known, a detailed description will be omitted. After the vehicle is accommodated in the parking space 102 of the target floor, the CPU 306 of the PLC 304 outputs a driving signal through the inverter 318 for moving the lifter 108 to the entrance-level floor at step S314. This is so that the lifter 108 is on a standby state at the entrance-level floor in which the door 112 is installed so as to deliver another vehicle at step 318. At this time, the CPU 306 of the PLC 304 addresses data associated with the parking space and floor accommodating the vehicle with the vehicle number. It then stores the data into the memory 308. Next, the process returns to the step S302 and then the aforementioned process is repeatedly carried out. A vehicle exit process, which is not shown in Fig. 5, is carried out in a reverse order of the vehicle entrance process. The vehicle number, which is inputted by the driver or the operator of the parking facility, is retrieved from the memory 308. Then, the lifter 108 is elevated to a corresponding floor. Thereafter, the vehicle is moved to the entrance-level floor and exits through the door 112. Since the vehicle exit process is widely well known, a detailed description thereof is omitted herein.

DISCLOSURE OF THE INVENTION As described above, the conventional parking facility adopts a vehicle entrance/exit method accommodating the vehicle to a parking space, which is nearest from the entrance-level floor, or to an arbitrary parking space, hi case the vehicle is parked for awhile, the vehicle may be accommodated to a parking space, which is farthest away from the entrance-level floor, so that it takes a long time to deliver the vehicle. Therefore, there are problems in that the driver has to wait for a long time while the power consumption increases. Accordingly, a vehicle entrance/exit operation is inefficiently carried out.

BEST MODE FOR CARRYING OUT THE INVENTION Fig. 6 is a schematic block diagram illustrating a manipulation module and a control module of a vehicle entrance/exit system in an elevator-type parking facility in accordance with the present invention. The parking tower can be configured identically to that illustrated in Figs. 1 and 3. As such, a detailed description of the parking tower will be omitted herein. As shown in Fig. 6, the manipulation module 400 and the control module 500 communicate with each other through a communication line LI 4. The manipulation module 400 includes a manipulation unit 402 and a vehicle number input unit 410. The manipulation unit 402 includes a switching unit 404, a display unit 406 and a lamp unit 408. Since the functions of the manipulation module 400 are similar to those of the manipulation module 200 in Fig. 4, a detailed description of the functions of the manipulation module 400 will be omitted herein. The control module 500 includes a programmable logic controller (PLC) 504 and an inverter 518. The PLC 504 includes a central processing unit (CPU) 506, a memory 508, an input unit 510, an output unit 512, a customer comparing unit 514 and a communication unit 516. Since the PLC 504 in the control module 500 is similar to the PLC 304 in Fig. 4 except the memory 508 and the customer comparing unit 514, a detailed description for other parts except the memory 508 and the customer comparing unit 514 in the PLC 504 will be omitted herein. The memory 508 stores not only the data related to a vehicle number and a parking status, but also a floating customer table. The floating customer table is produced on the basis of a vehicle entrance/exit pattern and is configured with the data associated with customers, which tend to have a low vehicle entrance/exit frequency and a long parking time (hereinafter, referred to as floating customers), and data associated with the vehicle numbers of the floating customers. The entrance/exit pattern of the vehicles for classifying the floating customers includes a vehicle entrance/exit frequency and a parking time during a predetermined period (e.g., a day, a week, a month, a quarter or a year). If the vehicle entrance/exit pattern meets the predetermined requirement, that is, if the vehicle entrance/exit frequency is lower than the predetermined entrance/exit frequency and the parking time is longer than the predetermined parking time, then the customer is classified as the floating customer. Also, the floating customer can be classified with a plurality of classes according to the entrance/exit pattern of the vehicle. This is so that the classes can be used when the parking space is determined. The customer comparing unit 514 determines whether the customer parking the vehicle is the floating customer by comparing the vehicle number inputted by the driver or the operator with the vehicle numbers stored in the memory 508. If the customer corresponds to the floating customer in the comparison result of the customer comparing unit 514, then the CPU 506 of the PLC 504 controls the vehicle of the floating customer to be accommodated in the parking space, which is relatively farthest away from the entrance-level floor, among the multiplicity of empty parking spaces 102. On the other hand, if the customer does not correspond to the floating customer, the vehicle of the customer is accommodated to the parking room, which is relatively nearest to the entrance-level floor. Fig. 7 is a flow chart showing a vehicle entrance method in accordance with the present invention. Hereinafter, the vehicle entrance method in accordance with the present invention will be described in view of Figs. 1-3 and 6-7. If the vehicle entrance instruction is received from the switching unit 404 at step S502, then the CPU 506 of the PLC 504 outputs a door opening signal through the output unit 512 to open the door 112. This is so that the vehicle is loaded to the pallet 106 of the parking tower 100. The CPU 506 of the PLC 504 receives the data associated with the vehicle number outputted from the vehicle number input unit 410 of the manipulation module 400 through the communication unit 516 at step S504. The vehicle number is inputted by the driver or the operator of the parking facility, as mentioned above. The customer comparing unit 514 of the PLC 504 compares the vehicle number inputted from the communication unit 516 with the vehicle numbers of the floating customer table stored in the memory 508 and checks whether the inputted vehicle number exists in the floating customer table at step S506. If it is determined that the inputted vehicle number corresponds to the vehicle number of the floating customer at step S506, the CPU 506 of the PLC 504 controls a floor of a parking room, which is relatively farthest away from the entrance-level floor, to be set as a target floor at step S508. On the other hand, if it is determined that the customer does not correspond to the floating customer, the CPU 506 of the PLC 504 controls a floor of an empty parking space, which is relatively nearest to the entrance-level floor 112, to be set as a target floor. Next, the CPU 506 of the PLC 504 controls the data associated with the target floor to be outputted through the output unit 512 to the manipulation module 400 for display on the display unit 406. Further, the driving signal is outputted to the driving motor 110 through the inverter 518 such that the lifter 108 is elevated to the target floor at step S512. The CPU 506 of the PLC 504 checks whether the lifter 108 has arrived at the target floor on the basis of data received from the input unit 510 at step S514. If it is determined that the lifter 108 has not arrived at the target floor at step S514, then the process returns to the step S512 so as to continuously elevate the lifter 108. On the other hand, if it is determined that the lifter 108 has arrived at the target floor, the CPU 506 of the PLC 504 outputs a stop signal to the driving motor 110 through the inverter 518 so as to stop the elevation of the lifter at the target floor at step S516. Next, the CPU 506 controls the lifter 108 for accommodating the vehicle to the parking space of the target floor at step S518. After accommodating the vehicle within the parking space, the CPU 506 of the PLC 504 outputs the driving signal through the inverter 318 to the driving motor 110 so that the lifter 108 is moved at step S520. Therefore, the lifter 108 is on a standby state at the entrance-level floor for entrance of the next vehicle at step S522. At this time, the CPU 506 stores data matching the vehicle parking floor with the vehicle number, which represents a parking status, in the memory 508. Next, this process returns to the step S502 for performing the above process again. Fig. 8 is a flow chart showing a vehicle exit method in accordance with the present invention. Hereinafter, the vehicle exit method in accordance with the present invention will be described in detail in view of Figs. 1-3 and 6-7. At step S602, the CPU 506 of the PLC 504 receives the vehicle exit instruction from the switching unit 404 of the manipulation module 400 through the input unit 510 and data associated with the exit vehicle number from the vehicle number input unit 410 of the manipulation module 400 through the communication unit 516. The customer comparing unit 514 of the PLC 504 checks whether the inputted vehicle number accords with the vehicle number in the floating customer table stored in the memory 508 at step S604. If it is determined that the vehicle number does not correspond to the vehicle number of the floating customer, the lifter 108 is moved to the entrance-level floor at step S610. On the other hand, if it is determined that the vehicle number corresponds to the vehicle number of the floating customer, the CPU 506 of the PLC 504 retrieves data stored in the memory 508 to check whether the entrance/exit frequency of the vehicle in the vehicle entrance/exit pattern exceeds the predetermined frequency at step S606. Although the customer is classified as the floating customer, if the entrance/exit frequency is gradually increased by over the predetermined entrance/exit frequency, the customer can be excluded from the floating customer at step S606. If it is determined that the entrance/exit frequency is less than the predetermined frequency at step S606, the customer is maintained as the floating customer, although the entrance/exit frequency is higher than the usual entrance/exit frequency. This is so that the process proceeds to the step S610. On the other hand, if it is determined that the entrance/exit frequency exceeds the predetermined frequency at step S606, then the process proceeds to the step S608 in order to exclude the customer from the floating customer. At step S608, the CPU 506 of the PLC 504 deletes the data associated with the customer corresponding to the currently inputted vehicle number from the floating customer table stored in the memory 508, thereby updating the floating customer table. Next, the CPU 506 of the PLC 504 outputs the driving signal to the driving motor 110, thereby elevating the lifter 108 to the target floor in which the vehicle is accommodated at step S610. Thereafter, the vehicle is delivered to the entrance-level floor by the lifter 108 and exits through the door 112 at step S612. After the vehicle exits, the CPU 506 of the PLC 504 deletes the data associated with the outgoing vehicle number from the memory so that the parking status data stored in the memory 508 is updated at step S614. Thereafter, the process is completed. As described above, while the present invention exemplarily describes the process, in which the steps S608 to S614 are sequentially carried out, it will be apparent that variations and modifications are possible according to applications of the vehicle entrance/exit system and method. Namely, in case of excluding the floating customer from the floating customer table, after the vehicle exits, the parking status stored in the floating customer table and the memory 508 can be updated. Alternatively, after the parking status stored in the floating customer table and the memory 508 is updated, the vehicle can exit. In accordance with another embodiment of the present invention, the vehicles can be accommodated by using a resident table, a visitor table and an important customer table in addition to the floating customer table. For example, if the parking facility is established at buildings for residence and office, the resident table and the visitor table can be made by classifying the residents and visitors. Then, the vehicles can be accommodated to predetermined parking spaces similar to the method described in view of Fig. 7. This is so that the parking facility can be efficiently utilized. Namely, in case of the residents, the vehicle can be accommodated at an empty parking space, which is relatively far away from the parking door. In case of visitors, the vehicle can be accommodated at an empty parking room, which is relatively near the parking door. Also, if the parking facility is established at a business building such as a department store, the customers may be classified with important customers in addition to the floating customers. Then, the important customer table may be made. As the vehicle of the important customer is accommodated to an empty parking space, which is relatively nearest to the door, the vehicle entrance/exit can be rapidly carried out. This is so that a time waiting for the vehicle entrance/exit of the important customer can be reduced. Therefore, service satisfaction can be improved.

INDUSTRIAL APPLICABILITY In accordance with the present invention, the vehicles are accommodated after classifying the customers into the floating customers and non-floating customers on the basis of the entrance/exit pattern of the vehicles. The vehicles of the floating customers are accommodated to the empty parking spaces, which are relatively farthest away from the parking door. The vehicles of the non-floating customers are accommodated to the empty parking spaces, which are relatively nearest from the parking door. Therefore, the parking facility can be efficiently managed. Further, the life time of the parking facility may be lengthened and the cost for operating the parking facility can be reduced. Also, since the vehicles are accommodated by making the resident table, the visitor table and the important customer table in addition to the floating customer table, the parking facility can be efficiently utilized. While the present invention has been described and illustrated with respect to a preferred embodiment of the invention, it will be apparent to those skilled in the art that variations and modifications are possible without deviating from the broad principles and teachings of the present invention which should be limited solely by the scope of the claims appended hereto.
