Hereinafter, the working principle and embodiments of the present invention will be described with reference to the accompanying drawings.

First, an electric vehicle charged at an electric vehicle charging station according to the present invention will be briefly described. A vehicle that can be charged at an electric vehicle charging station has a motor. Therefore, a high-voltage battery is required to store power for driving the motor. Even in a general internal combustion engine vehicle, an auxiliary battery is provided on one side of the engine room. However, in the case of the electric vehicle vehicle 100, a large-capacity high-voltage battery is required.

A charging socket is provided in the electric vehicle vehicle 100 . The charging connector 151 of the external slow charger 150 is connected to the charging socket, so that the high voltage battery inside the electric vehicle can be charged. That is, when the charging connector 151 of the slow charger 150 is connected to the charging socket of the electric vehicle 100, the high voltage battery of the electric vehicle 100 is charged.

Hereinafter, it is assumed that the electric vehicle vehicle 100 is parked on the first surface of the parking lot where the slow charger 150 is installed, and the electric vehicle charging station occupancy monitoring system according to the present invention will be described.

1 and 2 are block diagrams illustrating the connection of an electric vehicle charging station occupancy monitoring system 10 and a slow charger 150 capable of charging an electric vehicle according to an embodiment.

An electric vehicle charging station occupancy monitoring system 10 according to an embodiment of the present invention may include a camera 11, a processor 12, a memory 13, a communication unit 14, and an input unit 15.

The camera 11 may acquire images of each side of the parking lot in which the slow charger 150 is installed. Here, 'surface' means a parking surface to be parked, and images of each of at least one parking surface included in the parking lot may be obtained. That is, the camera 11 acquires an image of a parked vehicle for each side, and thus obtains a license plate number of the parked vehicle.

In addition, when the vehicle is parked in the image, the camera 11 may record the vehicle information together with the video along with the entry time at which the vehicle was parked. It can be recorded with video.

At this time, the location where the camera 11 of the electric vehicle charging station occupancy monitoring system 10 is installed may vary. For example, a camera 11 may be installed in contact with the slow charger 150 to capture an image of the parking surface. That is, it is possible anywhere as long as it is easy to take an image including a parking surface.

However, it should be a location that does not interfere with the user parking the vehicle on the parking surface, and it is preferable that the location is easy to photograph the number of the vehicle. Therefore, the camera 11 is located inside the parking surface so that it is possible to photograph the number located at the lower end of the front of the vehicle when the vehicle is parked in front, or to photograph the number located at the lower end of the rear of the vehicle when the vehicle is parked backward. can be installed

The camera 11 may photograph the parking surface at regular time intervals. For example, the camera 11 photographs the parking surface at intervals of 20 minutes.

For example, even if the actual entry time of the vehicle is 1:50, if the camera 11 captures images at 1:40 and 2:00, 2:00 may be recorded as the entry time.

In addition, even if the actual departure time of the vehicle is 10:10, if the camera 11 captures images at 10:00 and 10:20, 10:20 may be recorded as the departure time.

Next, the processor 12 is responsible for the overall process of the electric vehicle charging station occupancy monitoring system 10 . That is, information obtained by photographing vehicles entering and exiting the parking surface is received from the camera 11, and the vehicle number is recognized by analyzing the received image information.

That is, the processor 12 performs vehicle number recognition from the input image information through a number recognition algorithm. At this time, the processor 12 facilitates number recognition even when number recognition is difficult due to light reflection or light bending, when number recognition is difficult from various license plate types, or when number recognition is difficult due to various parking types of a vehicle. A prepared number recognition algorithm may be included.

Specifically, the camera 11 may be positioned to face the license plate of the vehicle so that it may be easy to recognize the number of the license plate when taking a picture. there is. In this case, the processor 12 analyzes the image received from the camera 11 and obtains the license plate number.

In addition, the processor 12 analyzes the image of the camera 11 to secure the entry time and exit time, and calculates the occupancy time of the vehicle from the secured entry time and exit time. That is, the vehicle occupancy time can be secured by calculating the time interval (t2-t1) between the entry time t1 and the exit time t2.

Also, the processor 12 obtains information about the charging time of the parked vehicle from the slow charger 150 . That is, when the charging connector 151 of the slow charger 150 is connected to the charging socket of the electric vehicle vehicle 100, the high voltage battery of the electric vehicle 100 is charged, and the processor 12 starts charging from the slow charger 150. Information on the required time from the point in time until the battery is fully charged may be obtained. In this case, when receiving corresponding information from the slow charger 150, the corresponding information may be obtained through the communication unit 14 of the electric vehicle charging station occupancy monitoring system 10.

At this time, a method for the communication unit 14 to receive the buffer information from the slow charger 150 can be both wired or wireless communication, and the communication unit 14 will be described in detail below.

The processor 15 may inform the user of information about a fully charged time point by comparing information about a fully charged charging time of the parked vehicle from the slow charger 150 with an entry time t1 of the parked vehicle.

For example, when the vehicle enters the vehicle at 2pm (2pm) and the vehicle charging time required (9h) is received from the slow charger 150, the user is notified of information about the charging end point (t3: 11pm). can

That is, the processor 15 calculates the buffer end time t3 from the buffer required time and the entrance time, and informs the user of information about the corresponding buffer end time. At this time, the corresponding information is transmitted to the user through the communication unit 14 of the electric vehicle charging station occupancy monitoring system 10.

In addition, the information transmitted to the user through the communication unit 14 of the electric vehicle charging station occupancy monitoring system 10 includes not only information about the charging end point, but also charging status information. That is, the processor 12 may calculate charging status information upon a user's request and deliver the corresponding information to the user again.

It is common for the communication unit 14 to inform the user of information about the buffer end point by performing a wireless communication method, which will be described in detail below.

As an example, assuming that wireless communication is supported so that the user performs data communication with the electric vehicle charging station occupancy monitoring system 10, when the user checks the charging amount information in the electric vehicle charging station occupancy monitoring system 10, The EV charge occupancy monitoring system 10 may deliver information about the current state of charge, the amount of remaining charge, and the estimated time required to fully charge again to the user.

Also, when the corresponding vehicle is not taken out of the vehicle even at the buffer end time point t3, the processor 12 may notify the user that the vehicle is fully charged again at the buffer end time point t3.

That is, the processor 12 transmits the corresponding information to the user through the communication unit 14 of the electric vehicle charging station occupancy monitoring system 10, similarly, if the corresponding vehicle continues to be occupied after the entry time t1 at the fully charged end time point t3. send out At this time, as to whether or not the occupancy continues, a case in which the vehicle maintains its position without moving in the image information photographed from the camera 11 may be regarded as the continued occupancy state. In addition, it is common for the communication unit 14 to notify the user that the battery is fully charged by performing a wireless communication method, which will be described in detail below.

In addition, the processor 12 may notify the user of the buffer end time point t3 and at the same time send information indicating that the vehicle must leave the vehicle after a predetermined critical time. For example, the processor 12 may transmit information to the user indicating that the vehicle must be parked within 1 hour (threshold time) from the buffer end point t3.

However, when the vehicle maintains the continuous occupancy state and the buffer end point t3 is early in the morning or late at night, the corresponding threshold time may be changed to a time after dawn of the next day.

For example, if the buffer end point t3 is expected to end between 10 pm and 8 am, information indicating that the vehicle should be removed at 9 am after 1 hour, which is a critical time, from 8 am may be transmitted to the user.

The processor 12 may employ wireless communication of the communication unit 14 to transmit information on the buffer time, information on the buffer end point, and departure time information to the user.

That is, the communication unit 14 can perform both wireless communication and wired communication. At this time, wired communication may be used to receive vehicle buffer information from the slow charger 150 .

In addition, if the slow charger 150 has a dial pad, the vehicle number input by the user and the mobile phone number of the user input by the user may be input through the communication unit 14 . Specifically, as another embodiment of the present invention, FIG. 2 is a block diagram illustrating a case in which a user's vehicle number and a user's mobile phone number can be input through the display 152 included in the slow charger.

That is, although it has been described above that the slow charger 150 has a dial pad, the user's vehicle number and mobile phone number are received through the display 152 including a touch screen, and the information is received through the communication unit 14. can

If the slow charger 150 does not have a dial pad, the user may receive a vehicle number or a mobile phone number of the user through the input unit 15 provided in the electric vehicle charging station occupancy monitoring system 10.

That is, when the vehicle number is input through the input unit 15, the electric vehicle charging station occupancy monitoring system 10 compares the image captured by the camera 11 with the number recognized by the processor 12 to determine the vehicle number. can

In addition, when the user's mobile phone number is input through the input unit 15 or when the user's mobile phone number is input from the slow charger 150, the communication unit 14 in the electric vehicle charging station occupancy monitoring system 10 transmits the user's mobile phone number. Information on the buffer time, information on the end of the buffer, and departure time information are sent to the mobile phone number.

At this time, the input unit 15 is composed of a touch pad or a dial pad, and various methods of receiving a number from the user may be possible.

In addition, the processor 12 may analyze a usage pattern based on the entry time, exit time, and buffer information of the entered vehicle. At this time, the processor 12 only stores the entry time, exit time, buffer information, etc. of the entered vehicle, and a server (not shown) of the system 10 may also analyze the use pattern of the corresponding data.

For example, it is possible to analyze usage patterns according to spatial characteristics in which the electric vehicle charging station occupancy monitoring system 10 according to the present invention is installed. Specifically, a usage pattern of the first monitoring system 10A installed in an apartment and the second monitoring system 10B installed in a department store may be analyzed and transmitted to a server that comprehensively manages the electric vehicle charging station occupancy monitoring system 10 . That is, it is possible for the server to analyze the usage pattern, and the system 10 to differently set the threshold time to perform mobile parking (exiting) after buffering based on the analyzed usage pattern.

As another example, it is possible to analyze usage patterns according to temporal characteristics in which the electric vehicle charging station occupancy monitoring system 10 according to the present invention is installed. Specifically, it is possible to induce an increase in the circulation rate of parking by analyzing the difference in use patterns by day and night. As described above, when the vehicle maintains the continuous occupancy state, when the buffer end point t3 is early in the morning or late at night, the corresponding threshold time may be changed to a time after dawn of the next day. there is.

As another example, it is possible to analyze usage patterns according to user characteristics in which the electric vehicle charging station occupancy monitoring system 10 according to the present invention is installed. Specifically, it is possible to analyze different usage patterns according to vehicle types (large/medium/small).

That is, by installing the electric vehicle charging station occupancy monitoring system 10 according to the present invention, big data is analyzed to derive a solution to prevent long-term parking by analyzing the spatial characteristics of the electric vehicle charging station, temporal characteristics, and user characteristics. collection may be possible.

Next, the communication unit 14 will be described in detail later. Wireless communication of the communication unit 14 included in the electric vehicle charging station occupancy monitoring system 10 according to the present invention can be adopted by changing the existing router structure to a communication modem through modularization. In addition, communication may be performed using a data-only USIM to reduce communication charges of the communication unit 14 included in the electric vehicle charging station occupancy monitoring system 10 .

In addition, the communication unit 14 may be used by a national agency (e.g.: Korea Transportation Safety Authority) in case the input unit 15 does not operate properly (malfunction) or in the case of the electric vehicle charging station occupancy monitoring system 10 in which the input unit 15 does not exist. Corporation) It is possible to secure the user's mobile phone number that matches the vehicle number from the server. However, since the user's mobile phone number corresponds to personal information, it may be possible to secure the mobile phone number only when it falls under the smart city regulatory sandbox. Here, 'regulatory sandbox' refers to a space that allows empirical testing with restrictions on time, place, and scale to support the smooth progress of new technologies and services. That is, in a city corresponding to a smart city, it may be allowed to secure a mobile phone number of a parked vehicle limited to a place where an electric vehicle charging station occupancy monitoring system is installed based on the present invention.

Next, the memory 13 included in the electric vehicle charging station occupancy monitoring system 10 stores various types of information for smooth operation of the electric vehicle charging station occupancy monitoring system. Specifically, the memory 13 can store various data necessary for the operation of the processor, and includes flash memory, ROM (Read Only Memory) as well as volatile memory such as S-RAM and D-RAM. ), Erasable Programmable Read Only Memory (EPROM), and Electrically Erasable Programmable Read OnlyMemory (EEPROM).

The non-volatile memory can semi-permanently store a control program and control data for controlling the operation of the electric vehicle charging station occupancy monitoring system 10, and the volatile memory reads the control program and control data from the non-volatile memory and temporarily stores them. and temporarily store various sensor information and various control signals output from the main processor.

The schematic diagram of (a) schematically shows the charging amount display screen of the camera 11 (CCTV), the router of the communication unit 14, and the slow charger 150 for photographing the vehicle parked on the parking surface of the first surface.

That is, the electric vehicle charging station occupancy monitoring system 10 photographs the vehicle number of the occupied vehicle through the camera 11 (CCTV), and internally the processor 12 analyzes the image to secure the vehicle number. That is, the vehicle number recognized in the embodiment of FIG. 3 is '52 week 3108'. In addition, the electric vehicle charging station occupancy monitoring system 10 can secure the entry time and exit time of the vehicle through the camera 11 . In addition, it is possible to secure charge amount information and full charge time information from the slow charger 150 .

Next, the schematic diagram of (b) shows occupancy vehicle number, occupancy time, and buffer time information stored or calculated in the processor 12 and memory 13 in the electric vehicle charging station occupancy monitoring system 10.

In addition, the schematic diagram of (b) shows that when user information corresponds to some regulatory sandbox, driver information (mobile phone number) can be received from the server and secured in the processor 12 and memory 13.

Therefore, as shown in the schematic diagram of (c) shown based on the occupied vehicle number, occupancy time, buffer time, and driver information shown in (b), text message or data communication notifying the user to move the vehicle with charging information based notifications can be delivered.

4 and 5 are flowcharts illustrating an operation of an electric vehicle charging station occupancy monitoring system according to an embodiment.

First, as shown in FIG. 4 , the camera 11 of the electric vehicle charging station occupancy monitoring system 10 photographs the parking surface (400). That is, the camera 11 may photograph the parking surface at regular time intervals to capture whether or not the vehicle is occupied, such as entering or exiting the vehicle.

When the vehicle is entered (vehicle parking) (YES in 410), the electric vehicle charging station occupancy monitoring system 10 determines that the occupancy starts (420). Accordingly, the system 10 obtains charge amount information from the slow charger 150 . At this time, the information on the amount of charging to be obtained includes information on the charging time and information on the charging end point, which includes a charging required time.

If the occupied vehicle continues to occupy the vehicle until the charging end point (YES in 440 and 450), the system 10 performs buffer information and vehicle exit notification to the user (460). However, when the vehicle maintains the continuous occupancy state and the buffer end point t3 is early in the morning or late at night, the corresponding threshold time may be changed to a time after dawn of the next day.

Next, FIG. 5 is a block diagram illustrating an embodiment in which a user obtains vehicle charging information using the electric vehicle charging station occupancy monitoring system 10 according to an embodiment.

First, it is assumed that the occupancy of the vehicle starts on the first surface of the parking lot in which the electric vehicle charging station occupancy monitoring system 10 is installed (S510). Step S510 may be the same as determining (420) that the occupancy monitoring system 10 of the electric vehicle charging station starts occupying the vehicle in FIG. 4 (vehicle parking) (Yes of 410).

When the vehicle is occupied, the system 10 transmits the occupancy start information to the user terminal 1000 (S520). That is, it can be assumed that the wireless communication between the user and the system 10 can be connected at any time by transmitting the occupancy start information to the user terminal 1000 . At this time, the wireless communication between the user and the system 10 is when the user inputs the user's mobile phone number through the display 152 of the slow charger 150 or the user enters the user's mobile phone number through the input unit 15 of the system 10. A connection of wireless communication between the two may be established through a method of inputting .

If the user requests the system 10 to check the vehicle charge amount information through the user terminal 1000 (S530), the system 10 checks the charging information from the slow charger 150 (S540), and the corresponding information may be delivered to the user terminal 1000 again (S550).
