Empty Parking Lot Indicator {Indication of Empty Parking Lot}

The present invention relates to an empty parking space notification indicator, in particular, in a large parking lot so that vehicles entering the parking lot can check the parking indicators displayed on the passage part of each parking space so that the available space can be easily found and parked. One empty parking space alert indicator.

As the number of vehicles gradually increases, and the number of people who seek convenient things increases, the number of people who go to various large department stores and buildings use their own vehicles is increasing the parking space, and thus the parking lot is becoming larger and larger. In addition, as the parking lot becomes larger, companies or buildings with convenient parking facilities are becoming a preferred destination for visitors. However, despite the increase in the number of large parking lots, the parking management system often fails to meet user needs.

If you want to park your car in a large parking lot up to now, check the indicator at the entrance of the parking lot or get a guide to check the empty parking floor and enter the vehicle, and go through the parking space where several cars are parked and check the empty parking space. There was a problem to park. In addition, for this purpose, it is difficult for the parking lot manager to improve the parking facilities due to the burden on the cost of expanding the parking facilities and installing various facilities.

The empty parking space notification indicator according to the present invention, in order to solve the inconvenience of parking, the vehicle enters the entrance of the parking lot and simultaneously checks the empty parking space so that the vehicle can be parked easily. It reduces congestion, reduces the time used for parking, and makes it easier to use the parking lot. This reduces the time spent on parking, thereby reducing the wasted fuel costs (Gas) and reducing emissions from vehicles, thereby minimizing the pollution of the surrounding air. In addition, by reducing the number of personnel required for the management of parking spaces, labor costs of personnel required for management can be reduced, and the burden of expanding and improving parking facilities can be reduced by facilitating the installation and management of empty parking space notification indicators. There is a purpose.

The empty parking space notification indicator according to the present invention serves as an empty space indicator for displaying an empty parking space of the parking lot. To this end, the transmitter / receiver of the sensor for detecting the presence of the vehicle on the ceiling of each parking space; The controller controls the sensor and displays the signal input through the lamp through the lamp; so that it can be individually managed by installing a separate, and if the integrated control of the empty parking space indicator managed separately, each device, A sub controller configured to connect a data line connected to the installed control unit; A central controller to display information on each floor or in a predetermined area, and to control the data line of the sub controller; By connecting to the control room so that you can see the current status of the entire parking space at a glance, by processing the signal sent by the central control unit, the display board to visually display this so that the driver knows how many parking spaces are empty; Through this, it is easy to know at the entrance of the parking lot, so that the car can easily find an empty parking space when entering the parking lot.

The present invention is to solve the temporary congestion at the entrance of the parking lot by installing a lamp (Lamp) that functions to tell that the empty space and not the empty space in each parking space to easily find the empty parking space at the entrance of the parking lot, Finding a parking space to eliminate the inconvenience of having to go around the parking lot. This reduces the amount of gas (Gas) required for parking and reduces the waiting time to find a parking space, thereby reducing the amount of exhaust gas emitted during the waiting time, thereby reducing air pollution in the parking space. In addition, when the central control unit is installed, it is possible to install and use only individual sensors and control units installed in each parking space that can be managed individually instead of replacing them entirely.

Hereinafter, an empty parking space notification indicator will be described with reference to the accompanying drawings.

1 is a block diagram of a device according to the present invention. Referring to the configuration of the device according to the present invention with reference to the accompanying drawings as follows. In the equipment installed in each parking space, the power input through the power line (6, 220V power line) is converted into the use power through the power supply unit (5, Adapter) is supplied to the control unit (4). Each control unit 4 has a different serial number. The control unit 4 transmits a signal including a unique number through the transmitting unit 3 of the sensor to check whether the vehicle is parked in the parking space. The transmitted signal is reflected by the parked vehicle and input through the receiver 7 of the sensor, and the receiver 7 transmits the input signal to the controller. The transmitted signal is analyzed through the control unit 4 (comparative analysis of the transmitted unique number and the received unique number, and self-diagnostic function analysis) to determine whether the vehicle is parked or not, and whether the device is abnormal. It is indicated through part (1). In addition to a plurality of individual controllers, if a sub-controller (9, Sub Controller) is used for management of each floor or a certain area, vehicle parking of each parking space is additionally determined through a data line (8) connected to each control unit (4). The information sent to the control unit 9 and analyzed and analyzed is displayed on the display board. In order to centrally control the system managed by each floor or zone, the information of each sub-control unit 9 is collected by the central control unit 10, and the central control unit processes the information input from each sub-control unit to display the display board 99. Visualize and send information for integrated management to computer (x) so that it can be managed for each floor and device. In addition, by attaching a timer (99) to the power supplied to each device, it is possible to adjust the start time and end time of the operation of the device, to identify the time when the parking lot is utilized by floors and zones, When not in use, it stops operating without supplying power to the device to prevent power consumption.

2 is a view showing a transmission and reception method of sensor utilization for realizing the device according to the present invention. Hereinafter, a method of transmitting and receiving a sensor (a detection method of a parked vehicle) using a sensor for realizing a device according to the present invention will be described with reference to the accompanying drawings. A is a graph showing a transmission / reception distance of a sensor according to a resistor value. B is a diagram for explaining the transmission and reception distance of the sensor according to the resistance value (Block Diagram). In the control using an infrared sensor (I / R Sensor), changing the register value of the sensor stage changes the distance between the signals transmitted and received. In Fig. 2-A, when the resistance value of R1 is attached to the sensor transmitting end, the signal is transmitted and received at a distance of D. When the resistance value of R2 is attached to the sensor transmitter, the signal is transmitted and received at the distance of C, which reduces the transmission and reception distance. A detailed description using the above principle is shown in FIG. FIG. B is a diagram illustrating a method of self-diagnosing when there is a vehicle in a parking space and when there is no vehicle due to a transmission / reception distance of a sensor in FIG. Since the signal with the resistance value of R1 is transmitted and received at the distance as D, the distance from the ground to the signal can be received d (the distance from the sensor to the floor, d = D / 2-n, 0 <n≤40cm, D is By setting the round trip distance that the sensor can transmit and receive, it is set to be shorter than D, the distance at which the signal with the resistance value of R1 is transmitted and received, so that the transmitted signal must be received. Since the resistance value R1 is used as a self-diagnosis program, it functions to signal when a transmitted signal is not received. Since the signal with the resistance value of R2 is transmitted and received at the distance of C, the distance to the target point is set to c (the distance from the sensor to the target point to the height when a small car such as a passenger car is parked so that the signal can be received). C = C / 2-n, 0 <n≤40cm, where C is the round trip distance that the sensor can transmit and receive) and set it to be shorter than C, the distance at which the signal with the resistance of R2 is transmitted and received. If there is a small car such as a passenger car, the signal is received. If there is a vehicle that is receiving a signal and parked, check whether the parking space is turned off. If there is no vehicle parked because no signal is received, check the parking space. Turn on the power. Since the signal with the resistance value of R3 is transmitted and received at the distance as B, the distance to the target point is b (the distance from the sensor to the target point to the height of the vehicle, such as bongo, etc. B = B / 2-n, 0 <n≤40cm, where B is the round trip distance that the sensor can transmit and receive), and shorter than B, the distance at which the signal with the resistance of R3 is transmitted and received. If there is a small car such as a parked car, a signal is received. If there is a vehicle that is receiving a signal and parked, check the parking space. Turn on the power. Since the signal with the resistance value of R4 is received at the distance A, the distance to the target point is set to a (the distance from the sensor to the target point, which is not received at the height of the general vehicle, so that the signal can be received. , a = A / 2-n, 0 <n ≦ 40cm, where A is the round trip distance that the sensor can transmit and receive. A, which is the distance at which the signal with the resistance value of R4 is transmitted and received, is a distance that cannot be received at the height of a general vehicle, and thus no signal is received in all cases. Since the resistance value R4 is used as a self-diagnosis program, when the transmitted signal is received, it is treated as an error, and it checks whether the system has failed and makes an error signal when the error is confirmed.
