Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking induction and collision notification apparatus for guiding a vehicle from a parking lot to a parking space and notifying a possibility of collision between incoming and outgoing vehicles.

Recently, the spread of vehicles is rapidly increasing, and the parking space is getting scarce because the population is concentrated in the cities. Especially, it requires more parking space in large buildings, department stores, government offices, sports facilities, performance facilities and viewing facilities, which are used by many people with a lot of floating population and efficiently manage entry and exit vehicles, It is necessary to increase the parking efficiency and eliminate the vehicle lag.

That is, when the occupancy rate of the parking space is low in the parking facility, that is, when the parking space is sufficient, it is easy to identify the empty parking space and the parking lot can easily be parked in the vehicle. However, Since the identification of the parking space is difficult, the driver has to repeat the roaming within the spearhead or wait until the parking space is empty. Further, in consideration of this point, there is a limit in guiding the space of the large parking lot even when the parking guide is arranged, and the parking management cost such as an excessive labor cost is increased when a large number of the guide sources are arranged.

In consideration of this point, recently, a detector for recognizing whether or not parking has been installed in each parking space, and a flashlight is installed on the back of a parking space or a ceiling of a parking space according to a signal of a detector, or blinks red or green, And a method of guiding a vehicle to be parked is being applied.

However, according to the conventional method, there is a problem that the installation cost is increased, the maintenance such as failure is difficult, and the cost is increased because a detector, a blinking light or a guide light must be installed in each parking space.

In addition, since the driver of the vehicle entering the vehicle in the wide parking space finds a vacant parking space or finds or watches only an indicator lamp that indicates an empty parking space, the driver can not recognize the vehicle entering the negotiation section from the other side, There is a high possibility of an accident, and problems such as multiple vehicles entering along a narrow parking induction path may become entangled in a crossing section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a parking induction and collision notification apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1 and 2, a parking induction and collision notifying device according to an embodiment of the present invention includes a vehicle collision detection device for detecting a collision in a crossing area A1, A2, ... between a vehicle movement path 10, And to guide the vehicle by checking the number of parking spaces by the parking zones (B1, B2, B3., B4, B5, B6, ...).

The parking induction and collision notifying apparatus 100 according to an embodiment of the present invention includes a signal output unit 110, a first sensing unit 120, a second sensing unit 130, a third sensing unit 140, A storage unit 150, and a control unit 160.

The signal output unit 110 outputs a collision avoidance signal and a parking induction signal to the vehicle 30 entering and exiting the intersection areas A1, A2, ... among the vehicles moving along the movement paths 10, . Specifically, the signal output unit 110 includes an anti-collapse blinker 111 and a parking guide lamp 113. The collision-preventive blinker lamp 111 is installed at the center of the crossing areas A1, A2, ... and is flickered in accordance with the control signal of the control unit 160 so as to approach the crossing areas A1, A2, The driver of the vehicle is guided to check whether there is a vehicle approaching the intersecting areas A1, A2, ... so as to enable slow running so as to prevent collision in the intersecting areas A1, A2, ... .

The parking guide lamps 113 are arranged on the entrance side of the parking zones B1, B2, B3, B4, B5, B6, ... in the intersecting zones A1, A2, And is provided to output a parking induction signal to the parking zone as a lighting signal. That is, three or four parking guide lamps 113 are provided for each of the intersection areas A1, A2, ..., and are symmetrically arranged in three directions to four directions with the collision-resistant flasher 111 as the center. The parking guide lamp 113 may be illuminated green when parking is guided, and may be illuminated with red or the like in an unlit state when parking guidance is not performed.

In addition, the lighting colors of the parking guide lamps 113 are displayed on the basis of the places where the number of parking spaces is large for each parking area (B1, B2, B3., B4, B5, B6, It is possible. For example, it may be configured to be divided into a green light, a yellow light, and a red light. Therefore, when the number of parking spaces is the largest, or when the number of parking spaces is equal to or greater than the reference number, green lights are turned on to induce parking. If the number of parking spaces is less than the number of parking spaces, So that the parking area can be controlled to turn on or off the red light. Accordingly, the driver can find parking spaces with more room for parking.

The parking guide lamps 113 are divided into green lights, yellow lights, and red lights based on the occupancy rates of the parking spaces by the parking zones B1, B2, B3., B4, B5, B6, And may be controlled to be displayed. For example, when the occupancy rate is 50% or less, green may be displayed. When the occupancy rate is 50% to 99%, a yellow color may be displayed. When the occupancy rate is 100%, red may be displayed to indicate parking.

The crash-proof blinker lamp 111 and the parking guide lamp 113 having the above-described structure are preferably embedded in the floor, and may be installed in an upper space of a certain height from the floor surface .

The first sensing unit 120 senses and counts the vehicle 30 approaching the intersection areas A1, A2, .... The first sensing unit 120 is installed to be spaced apart from the vehicle moving path 10 or 20 in the direction of vehicle movement so as to sense a vehicle entering the intersecting zone A1, And a pair of first and second proximity sensors 121 and 122. That is, the first and second approach sensors 121 and 122 are provided for each of the vehicle movement paths 10 and 20 on the basis of the intersection areas A1, A2, ..., and the intersection areas A1, A2, ) For each lane of the travel route. Accordingly, when the first approach detecting sensor 121 detects the vehicle first and then the second approach detecting sensor 122 detects the vehicle, the vehicle enters the crossing areas A1, A2, ... It is possible to count the incoming vehicle.

The second sensing unit 130 senses a vehicle passing through the intersection areas A1, A2, ... and counts the vehicle. The second sensing unit 130 senses the vehicle passing through the crossing areas A1 and A2, ... sensed by the first sensing unit 120 in the vehicle movement paths 10 and 20, And first and second passage sensors 131 and 132 spaced apart from each other with respect to a moving direction of the vehicle. The first passage sensing sensor 131 is installed closer to the intersection areas A1, A2, ... than the second passage sensing sensor 132. [ Therefore, when the first passage sensing sensor 131 senses the vehicle and then the second passage sensing sensor 132 senses the vehicle, the vehicle passing through the intersection areas A1, A2, The moving direction of the vehicle can be detected. Therefore, since it is easy to check where the parking area the vehicle that has passed through the intersection areas A1, A2, ... enters for parking, it is possible to calculate and manage the number of parking spaces in the parking area, The occupancy rate and the number of parking spaces can be easily identified and managed.

Of course, the first sensing unit 120 senses a vehicle coming from the parking zone and transmits the counted information to the control unit 160, so that the number of parking spaces for each parking zone can be calculated again and stored in the storage unit 150 .

The third sensing unit 140 is installed at a position farther from the intersection areas A1, A2, ... than the first and second sensing units 120 and 130 to detect a vehicle. Respectively. The vehicle detection sensor 141 senses the vehicle at a position farther than the intersection areas A1, A2, ... before the first sensing unit 120 senses the vehicle and outputs a collision prevention signal, To prevent the vehicle from overtaking at a distance from the zones A1, A2, ... and traveling to the intersecting zones A1, A2, ....

Each of the first sensing unit 120, the second sensing unit 130, and the third sensing unit 140 may be embedded in the floor surface or installed on the ceiling of the parking lot.

The storage unit 150 stores and manages the number of vehicles to be accommodated and the occupancy rate information for each parking area of the parking lot B1, B2, B3, B4, B5, B6,. That is, in the storage unit 150, information on the number of parking spaces of the entire parking lot, the number of parking spaces for each parking zone as well as the information of parking and departing vehicles are received in real time, do.

The control unit 160 controls the signal output unit 110, that is, the parking guide lamp (not shown), based on the information sensed by the first sensing unit 120 and the second sensing unit 130 and the information stored in the storage unit 150 113) so as to output a vehicle induction signal for guiding the vehicle to the parkable parking area. Specifically, the control unit 160 controls the first sensing unit 120 to detect the presence of the vehicle in the parking area in which the vehicle has entered and the parking area in which the vehicle has come in according to the counted vehicle information detected by the second sensing unit 130 And the updated information is stored in the storage unit 150 and managed. Accordingly, the control section 160 controls the lighting operation of the parking guide lamp 113 in consideration of the newly updated occupancy rate of each parking zone, etc., thereby guiding the vehicle to the parking zone or the parking zone having a low occupancy rate.

The control unit 160 receives the vehicle sensing signal from the first sensing unit 120 and the third sensing unit 140 and controls the operation of the collision-preventing blinking light 111 so that the intersection areas A1, A2, . By providing an anti-collision signal to the vehicle, it is possible to prevent collision due to vehicle overspeed. That is, when the third sensing unit 140 senses a vehicle far from the intersection areas A1, A2, ..., the flashing blinker 111 for blink prevention is driven to blink, (A1, A2, ...) at the overspeed. Since the first sensing unit 120 can sense the vehicle coming from the parking zone close to the intersection areas A1, A2, ..., the collision-preventing blinker 111 is blink-driven to effectively perform the vehicle collision .

Effects of the parking induction and collision avoidance apparatus according to the embodiment of the present invention having the above-described configuration will be described in detail.

First, as shown in FIG. 1, when the vehicle 30 enters the vehicle movement path 10 at an entrance, the vehicle detection sensor 141 detects the vehicle, and the detection signal is transmitted to the control unit 160 . The control unit 160 controls the collision avoidance blinker 111 installed in the adjacent crossing area A1 to be flickered based on the signal detected by the vehicle sensor 141 so that the driver can overspeed the intersection zone A1 It is possible to induce the user to carefully drive and pass while checking the surroundings slowly without passing through.

1 and 3, when the occupancy rate of the B4 parking zone is 100%, and the occupancy rate of the B3 parking zone and the B5 and B6 parking zones are not 100%, the controller 160 The parking guide lamp on the B4 side of the parking guide lamp 113 lights up in red and the parking guide lamp on the B3 side and the parking guide lamp 113 on the next intersection area A2 are lit in green so that the driver can turn on the green induction signal of the parking guide lamp 113 Therefore, it is possible to enter the parking zone B3 which can be parked. That is, in FIG. 3, the vehicle 30 passes through the crossing area A1 and can turn right into the parking area B3 as shown by a virtual line in accordance with the parking induction signal. Then, the vehicle 30 entering the parking zone B3 is detected and counted by the first and second passage sensors 131 and 132. Accordingly, the controller 160 determines that the vehicle has entered the B3 parking zone through the vehicle and the vehicle traveling direction detected by the first and second passage sensors 131 and 132, and counts the number of parking spaces in the B3 parking zone It is possible to store and manage the data in the storage unit 150.

 4, when the vehicle 30 'parked in the parking zone B4 leaves the parking space and enters the vehicle movement path 20, the vehicle detection sensor 141 detects the vehicle 30' And transmits it to the control unit 160. Then, the control unit 160 controls the blinking blinker 111 to be blinkingly driven, so that drivers of other vehicles can be prevented from approaching the intersection area A1 by speed, and can be guided to approach with care.

In addition, the vehicle 30 'coming out of the B4 parking area and entering the crossing area A1 is sequentially sensed by the first and second proximity sensors 121 and 122 provided at the exit side of the B4 parking area, 160, respectively. Accordingly, the controller 160 confirms that one vehicle 30 'is out of the B4 parking zone, updates the number of parking spaces of the B4 parking zone to be one, and stores and manages it in the storage unit 150. [

When the vehicle 30 'that has exited the B4 parking area and has passed the intersection area A1 is moved to the right by turning to the exit side as shown in FIG. 5, the first and second passage detecting sensors 131 and 132 detect the vehicle 30 ') in the direction of movement of the vehicle 30', thereby confirming that the vehicle has moved to the exit side. Of course, entrance and exit sensors can be installed on the entrance side to detect the entry and exit of the vehicle, so that the entry and exit vehicles can be counted.

As described above, according to the parking induction and collision notifying apparatus according to the embodiment of the present invention, the moving direction of the vehicle is detected on the vehicle moving paths 10 and 20 of the parking lot, B1, B2, B3., B4, B5, B6, ...) and update the number of vehicles entering the vehicle in real time. Accordingly, it is possible to easily grasp and manage the number of parking spaces (occupancy rates) of the parking zones B1, B2, B3., B4, B5, B6, ... using the first and second sensing units 120, So that the control unit 160 can selectively turn on green, yellow, and red lights on the parking guide lamp 113 in the intersecting areas A1, A2, ... so as to guide the vehicle to the parkable parking area do.

In addition, by causing the collision-resistant blinker 111 installed in the crossing areas A1, A2, ... to be flickered when the vehicle approaches the crossing areas A1, A2, ..., The collision can be effectively prevented.

In particular, in the case of the present invention, it is not necessary to provide sensors for detecting a vehicle for each parking space for each parking area, 1 and the second sensing units 120 and 130 are installed, it is possible to minimize the number of sensors installed, thereby reducing the cost of the parking lot facility and reducing the maintenance cost, It is advantageous in that the cost of managing the parking of the vehicle can be remarkably reduced compared with the conventional one.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Those skilled in the art will readily appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
