In addition, the parking zone controller 18 compares vehicle presence detection information with information on the number of available parking lots and transmits parking state information including information on the number of parking spaces in which the parking space of the corresponding parking zone is full or empty to the upper link. do. The entrance allowance lamp 19 may be implemented as a red lamp that does not allow entry and a green lamp that allows entry.

The parking zone controllers 18 are connected to a main controller 20 located on the upper link. The main controller 20 stores information on the maximum number of available parking spaces for all parking areas PAi of the parking lot in an internal memory, and analyzes parking state information transmitted from the parking area controllers 18 by analyzing the parking state information transmitted from the parking area controllers 18. The number of available parking spaces for each parking area (PAi), the number of available parking spaces for the entire parking lot, and the parking area (PAi) to guide the vehicle entering the parking area (PAi), which is close to the entrance of the parking lot and can be parked. Drive a display lamp of the direction indicators 22 located in the passage state of the lamp.

Each of the direction indicators 22 is configured of a lamp of red, green, etc. to indicate the direction of travel under the control of the main controller 20 to guide the entering vehicle.

FIG. 3 illustrates a connection relationship between a loop coil and a driving sensor embedded in the stopper shown in FIG. 2 and a connection relationship between neighboring driving sensors. Referring to FIG. 3, located inside the parking detection stopper 10 installed in one parking space (OCPAi, OCPAj: where "i and j" are integers 1 to 4 as "i ≠ j"). The loop coil 12 is connected to the drive detector 14. The drive detector 14 provides a predetermined frequency signal to the loop coil 12, and detects a change in inductance of the loop coil 12 to detect whether or not a vehicle exists in the parking space OCPAi. In addition, the drive detector 14 further adds its own identification number to the parking detection data and transmits it through the daylines connected in parallel as shown in FIG. 3. In Fig. 3, reference numeral 16a is a power supply line, and 16b is a data line connected in parallel.

FIG. 5 is a view illustrating a control flowchart of a parking zone controller 18 in a parking guidance apparatus using a stopper having a parking sensor according to a preferred embodiment of the present invention.

6 is a flowchart of a parking guidance control of the main controller 20 of the parking guidance apparatus according to the preferred embodiment of the present invention.

With reference to FIGS. 1 to 6, an operation process of properly displaying and controlling the direction indicators 22 for guiding parking guidance to a driver riding in the vehicle will be described in detail with reference to FIGS. 1 to 6.

First, referring to FIGS. 3 and 4, an operation of detecting the presence or absence of a vehicle by the stopper 10 installed in the parking space OCPAi in each parking area PAi of FIG. 3 will be described below. When power is supplied to the power line 16a of FIG. 3 and the drive controller 14 is power-on reset in step S10 of FIG. 4, the drive controller 14 performs initialization in step S12. Set the reference frequency value (REF). As described above, the reference frequency value is a detected frequency value when the vehicle, which is set to determine the presence of the vehicle, is not parked.

In operation S14, the driving controller 14 provides a predetermined frequency signal to the loop coil 12 to detect a frequency value corresponding to the inductance value of the loop coil 12. Thereafter, the driving controller 14 compares the frequency value detected corresponding to the inductance value of the loop coil 12 with the preset reference frequency value REF in step S16 of FIG. 4 and stores the result in the internal memory according to the result. Stores vehicle presence detection information.

For example, when the detected frequency value corresponding to the inductance value of the roof coil 12 is larger than the reference frequency value REF, the drive controller 14 determines that there is a vehicle in the parking space OCPAi and the internal part at step S18. Vehicle detection information indicating that the vehicle is present is stored in the memory. If the detected frequency value corresponding to the inductance value of the roof coil 12 is smaller than the reference frequency value REF, the drive controller 14 determines that there is no vehicle in the parking space OCPAi and the internal part at step S20. Vehicle detection information indicating no vehicle is stored in the memory. The drive controller 14 that detects the parking presence by the initial power reset operation adds its own identification number to the parking detection information and connects the parking zone controller 18 linked to the upper level through the data line 16. Is sent to.

Accordingly, when the parking guidance guide device configured as shown in FIG. 2 is operated, the plurality of parking detection stoppers 10 installed in each parking area PAi may have no capacity in the corresponding parking space by the operation of the above power-on reset. It detects and transmits the result via the data line 16 to the corresponding parking area controllers 18. Each of the parking zone controllers 18 installed in correspondence with each parking zone PAi has parking capacity information of the corresponding parking zone PAi in an internal memory, and is transmitted from the parking detection stoppers 10. The parking detection signal detects a parking available state of the corresponding parking area PAi.

Referring to FIG. 5, the parking zone controller 18 reads the output of the parking detection stopper 10 installed in the corresponding parking zone PAi and detects the vehicle presence of the parking space OCPAi in step S22. Searches for an empty parking space (OCPAi). If it is determined in the search of the step S24 that there is no empty parking space OCPAi in the corresponding parking area PAi, the corresponding parking area controller 18 receives an entrance ramp installed at the entrance of the parking area PAi in step S26. 19) is driven into the entry disabled state, and the parking state information is transmitted to the main controller 20 located in the upper link with full parking.

If it is determined in step S24 that there is an empty parking space (OCPAi), the parking zone controller 18 determines the current parking space status information (OCPA_CT: One Car Parking Area_Current Table) and previous parking space status information in step S28. After comparing (OCPA_PT: One Car Parking Area_Past Table), it is determined whether the two information values are the same in step S30 to determine the parking state of the corresponding parking area PAi. That is, it is determined whether the vehicle parked in the parking area PAi is increased or decreased or there is no change.

If it is determined that the values of OCPA_CT and OCPA_PT are the same in the search result of step S30 of FIG. 5, since there is no change in the parking state, the parking area controller 18 jumps to step S22 and repeats the routine.

However, if it is determined that the values of OCPA_CT and OCPA_PT are different, the parking state of the parking area PAi is changed. And store, and drive the entrance indicator lamp 19 installed at the entrance of the corresponding parking area in a state of allowing (e.g., lighting a green light).

The parking zone controller 18 performing the S32 process transmits the parking state information, that is, the current parking space state information OCPA_CT, to the main controller 20 located in the upper link in the S34 process. At this time, the parking state information transmitted to the main controller 20 includes parking area identification information uniquely assigned to each parking area.

Meanwhile, in operation S36 of FIG. 6, the main controller 20 stores parking state information (for example, full vehicle information and available parking number) transmitted from the parking zone controllers 18 located in each parking zone PAi in the parking lot. If it is determined that the received parking space information) is received, the parking area PAi included in the data field received in step S38 is analyzed. Thereafter, the main controller 20 stores the state information OCPA_CT of the current parking space of the parking area PAi received in step S40 of FIG. 6 in the parking area state information area provided in the internal memory.

By the data reception analysis and storage operation as described above, the state information OCPA_CT of the current parking space for all parking areas PA1-PA4 is stored in the memory of the main controller 20. That is, it is possible to grasp the state of parking in the parking lot. Using this information, the main controller 20 can display the total number of parking lots in the parking lot on the indicator.

The main controller 20 performing the step S40 compares the values of all the parking areas PA1-PA4 at step S42, detects the parking area PAi having the smallest value, and is close to the parking lot entrance while empty. Sort the parking area PAi with lots of parking spaces (OCPAi). Thereafter, the main controller 20 calculates a value for lighting control of the direction indicator 22 positioned on the entry / exit passage of the parking area PAi in step S44 of FIG. 6, and in step S46, the direction indicator ( 22) to make it easier to find a parking area (PAi) with lots of empty parking spaces (OCPAi) close to the entrance to the parking lot.

In the above-described embodiment, the driving of the direction indicator 22 to guide the parking by receiving the sensing information of the parking area PAi has always been described, but may be operated differently. For example, as indicated by the dotted line in FIG. 6, after calculating the lighting control value of the direction indicator for inducing parking, the process returns to a process of searching for data reception, and when the vehicle is detected to enter, step S44 is performed. It is possible to apply a method of driving the direction indicator 22 for a predetermined time only when the vehicle is entered so that the vehicle is performed.

As described above, the parking guidance guide apparatus according to the present invention detects a vehicle parked in a plurality of parking zones and displays a parking entry permit / deny of the corresponding parking zone and transmits the information to the upper link at the same time. By appropriately driving the direction indicator located on the passage of the guided runner zone with a lot of empty parking spaces close to the entrance can make the use of the parking lot more convenient.
