Description

Communication repeater of parking management system

The present invention relates to a communication repeater of a parking management system for use in a large building or a large parking lot, and in particular, the license plate and the height of the vehicle according to the license plate of the vehicle entering the entrance while recognizing whether there is a vehicle parked in the parking area of the large parking lot. The present invention relates to a communication relay of a parking management system that enables efficient management of guidance and access to a parking area by allowing communication to be stably and quickly performed to properly guide a vehicle to a parking area after recognizing the type.

Nowadays, the increasing number of vehicles has led many people to drive their cars to their destinations, which often requires them to be parked in a parking lot until they have finished their work.

Therefore, in places such as department stores, public offices, large buildings, or parking buildings, where the vehicle is frequently accessed, the vehicle is in a state of controlling only the entrance of the vehicle while collecting the parking fee.

That is, when the vehicle enters through the entrance, if the driver takes a ticket to collect the fare, the driver opens the breaker to allow the vehicle to enter the interior, and when the parked vehicle exits the exit, it enters the entrance time recorded in the ticket. Therefore, after the appropriate fee was paid, the breaker must be opened after the fee was paid so that the vehicle could exit the parking lot.

However, in the conventional parking management system as described above, since the vehicle enters the interior of the parking lot and finds an empty parking space by itself, it takes a lot of time, and also pollutes the air by traveling at a low speed inside the parking lot for parking. In addition, many accidents occur such as time consuming and contact accidents of vehicles in a narrow space.

Therefore, a recent parking management system checks whether a vehicle is parked by sequentially calling each of the parking sensors from a central computer with a parking sensor that recognizes the presence or absence of a vehicle parked at each parking position. It is configured to induce parking.

However, in the conventional parking management system as described above, it is possible to select whether the vehicle is parked in the parking area of the parking lot or by using an ID and an internal sensor and driving units for guiding the state of receipt or leaving of the vehicle. Since there is no function, communication efficiency is not high, and each sensor or driving unit does not have a microprocessor for self-control, and thus, a lot of operating time is required, which makes fast and stable management difficult.

Accordingly, the present invention has been made to solve the above shortcomings, and an object of the present invention is to recognize whether a vehicle is parked in a parking area of a large parking lot while recognizing the type of vehicle according to the license plate and the height of the vehicle entering the entrance. It is to provide a communication repeater of the parking management system to enable the communication to guide the vehicle properly to the parking area after the stable and fast to enable efficient management according to the guidance and access to the parking area.

In order to achieve the above object, the present invention provides an ultrasonic sensor unit for recognizing whether a vehicle is a parking lot in a parking space, a beam array for measuring the height of the vehicle, a license plate recognition unit for recognizing a vehicle number, and a parking vehicle. A main controller that controls internal operations such as a fare calculator, a fare checker and a parking ticket issuing machine, while receiving a signal according to the presence or absence of a signal, information on the height of the vehicle, and information on the number of the vehicle, In the parking management system, which consists of guide signs and guides to guide the vehicle, the cables to which the parts are connected are routed through the communication repeater, and the data for communication is connected to the plurality of terminal blocks through the TTL logic of the resistor and condenser. The internal microprocessor receives the ID assigned to itself through the ID selector. By performing the operation by the program stored in the ROM while checking whether the vehicle is parked in the parking area, the license plate of the vehicle entering the entrance and the type of vehicle according to the height are recognized. It is configured to enable efficient management according to the guidance and entrance to the parking area by ensuring that the communication for guidance is performed stably and quickly.

Hereinafter, a parking management system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 schematically shows a parking management system according to an embodiment of the present invention. As shown in FIG. 1, the present invention recognizes whether a vehicle is parked in each parking space formed on several floors. A plurality of ultrasonic sensor units 1, a beam array 2 for measuring the height of a vehicle which is installed at the entrance of the parking lot and the branching points and the exit of each floor, respectively, and the entrance and the exit of the parking lot, respectively, The license plate recognition unit 3 for recognizing the number of the outgoing vehicle, and the signal according to whether there is a vehicle in the parking space of the vehicle from the ultrasonic sensor unit 1, the beam array 2 and the license plate recognition unit 3 and While receiving the information according to the height of the vehicle and the information according to the number of the vehicle, while controlling the operation of the communication controller (7), fare calculator (8), fare checker (9) and parking ticket machine (10), That is less control and a main controller (4).

In addition, the present invention under the control of the main controller (4) and the greetings for guiding the vehicle divided by the number and height of the vehicle to the empty parking space of the shortest distance and the guidance according to the number and parking position of the vehicle Guide signs (5) displayed in letters, and under the control of the main controller (4) are installed on the path that the vehicle proceeds to the parking space a plurality of guide lights for guiding the vehicle accurately by the state of sequential dots, lights out sequentially (6) is provided.
