Hereinafter, a method for providing parking lot information based on the above-described configurations with reference to FIG. 11 will be described in detail.
11 is a flowchart showing a method of providing parking lot information according to an embodiment of the present invention.
First, the terminal requests first information, which is information on the number of available parking spaces of the first parking lot, which is at least one of the plurality of parking lots, in the server (S10).
That is, the terminal receives the input of the parking lot from the user through the user input unit, and requests the server for the first information, which is information on the number of possible additions of the inputted parking lot.
In this step, the terminal may transmit the location information of the terminal together with the server.
Next, the server requests the first information to the counting system of the first parking lot (S20).
That is, the server requests the transmission of the first information to the counting system of the first parking lot in response to the request received from the terminal.
Next, the counting system of the first parking lot provides the server with the first information (S30).
That is, in response to a request for the counting system of the first parking lot, the counting system transmits information on the number of parking spaces of the first parking lot to the server.
Next, the server determines whether the number of available parking spaces of the first parking lot is less than a predetermined number (S40).
That is, in this step, it is judged whether or not information about another parking lot, which can be parked more easily, is provided if the first parking lot lacks the parking space.
If it is determined in step S40 that the number of available parking spaces of the first parking lot is equal to or less than the predetermined number, the server requests the second information, which is information on the number of parking spaces, to the counting system of the second parking lot located within a predetermined radius from the first parking lot S41).
This step is to guide the vehicle to the parking lot by providing information of other nearby parking lots when the parking space is insufficient in the first parking lot.
Next, the counting system of the second parking lot provides the server with the second information (S42).
Next, the server provides the first information to the terminal (S50).
