Referring to FIG. 4, the illegal vehicle tracking process according to the operation of the illegal vehicle tracking system according to an embodiment of the present disclosure may be divided into a total of five steps.

In detail, the illegal vehicle tracking process recognizes a vehicle entering by a surveillance terminal installed in a parking lot and captures it through a camera function, extracts a license plate from a photographed image, recognizes a vehicle number, and recognizes the vehicle number. And comparing and storing the illegal vehicle number, and if the vehicle is determined to be an illegal vehicle, transmitting the vehicle information and the location information to the illegal vehicle tracking server, based on the information received through the monitoring terminal, on the illegal vehicle tracking server. 4 steps to send the illegal vehicle information, location information and illegal matter information (non-payment, cannon, human, etc.) to the enforcement team; finally, the enforcement team dispatched to the location information to arrest the illegal vehicle and driver or to detect illegal vehicles in question. It can be divided into five stages.

On the other hand, Figure 5 schematically shows the configuration of the illegal vehicle tracking system that recycled used smartphone according to an embodiment of the present invention.

Referring to FIG. 5, the illegal vehicle tracking system 1 according to an exemplary embodiment of the present invention includes a loop coil sensor 10, a breaker 20, a monitoring terminal 30, a repeater 40, and an illegal vehicle tracking server 50. ).

The loop coil sensor 10 detects a vehicle that is buried and entered in an entrance passage of a parking lot. However, the exemplary embodiment of the present invention is not limited thereto, and the vehicle may be recognized using the motion detection function of the mobile phone terminal 31 applied to the monitoring terminal 30. Thus, the loop coil sensor 10 may replace a vehicle detection function in a parking lot without or without equipment.

The breaker 20 opens and closes the breaker bar 21 by operating a driving motor (not shown) according to a control signal applied thereto.

The monitoring terminal 30 captures a vehicle image with a built-in camera of the mobile phone terminal 31, recognizes a vehicle number of the vehicle image by using an operating system (OS) based license plate recognition engine module, and previews the recognized vehicle number in advance. If it is determined that the illegal vehicle is compared with the registered illegal vehicle number, the identification information (ID), the installation location information (GPS coordinates and GIS coordinate information) of the monitoring terminal 30, including the recognized illegal vehicle number and recognition time The event message may be generated and transmitted to the illegal vehicle tracking server 50 through the repeater 40.

Here, the mobile phone terminal unit 31 refers to an unopened air system and does not incur a separate mobile communication fee, but is a terminal in which at least the performance of a camera, an operating system (OS) and a short range wireless communication module is normally operated. In addition, wireless communication (eg, LTE, WIBRO, etc.) is possible through a dongle or a dongle if necessary.

For example, the monitoring terminal 30 may be mounted to the blocking bar 21 of the breaker 20 through a fixing bracket 331 provided in the housing 33 for casing the mobile phone terminal 31.

The repeater 40 is installed in the parking lot and relays wireless communication between the monitoring terminal 30 and other devices.

For example, the repeater 40 may be configured as a dongle for connecting a wireless LAN / WiFi router or a mobile communication network (eg, LTE), and various wireless communication supported by a known smart phone. It can be configured as a repeater.

The illegal vehicle tracking server 50 matches the terminal ID, the GPS, and the installed building / parking GIS coordinate information of the monitoring terminal 30 to form a DB, and the terminal ID included in the event message received from the mobile terminal 31. The location information of illegal vehicles is identified based on the illegal vehicle number.

The illegal vehicle tracking server 50 may share the detected illegal vehicle location information with the intermittent authorities such as the police station 50a, the tax office 50b, and the like to the enforcement unit terminal.

On the other hand, Figure 6 is a block diagram schematically showing the configuration of a monitoring terminal according to an embodiment of the present invention.

Referring to FIG. 6, the configuration of the monitoring terminal 30 according to the embodiment of the present invention is largely divided into three parts: a mobile phone terminal 31 having a camera function, a power supply of the mobile phone terminal 31, and an external connection with the outside. It includes a power supply control unit 32 and the housing unit 33 constituting the appearance of the monitoring terminal 30 to support the interworking.

The mobile phone terminal 31 utilizes a used smartphone as a hardware platform, and utilizes the software platform to provide a separate software module for each function to determine whether the illegal vehicle is through illegal vehicle photographing, vehicle number recognition, and analysis thereof. Configure. At this time, the software module for each function is in the form of application software (Application software, APP) that implements the main functions required for illegal vehicle monitoring according to an embodiment of the present invention based on the basic OS (Android or ios) provided by the smartphone Can be configured.

For example, the mobile phone terminal 31 may include an agent module 311, a communication module 312, a location information module 313, a camera control module 314, a vehicle number recognition module 315, and an illegal vehicle determination module 316. It may be configured to include.

The agent module 311 is modified to replace the ROM file mounted when the used smartphone is released to support the functions necessary to utilize the illegal vehicle monitoring terminal according to an embodiment of the present invention.

The agent module 311 controls the automatic booting function of the mobile phone terminal 31 to be described later, authorizes to control the function of each module for illegal vehicle monitoring, and connects external power and external communication. Interlock with the power supply control unit 32.

In particular, the automatic booting function is operated by the terminal itself without manipulating the power button and booting power when the power is turned off due to complete discharge of the battery while the external power supply of the cellular phone terminal 31 is cut off for various reasons. on) is not possible, and the illegal vehicle monitoring function in the field (on-site) and the illegal vehicle tracking server (50) side connection is impossible to manage because it is difficult to manage.

For example, the automatic booting function is a battery held by the mobile terminal 31 when the power supply from the outside is cut off due to various reasons such as power failure, system off test, light out, etc. When is discharged, the power is turned off. After that, even when the external power supply is resumed, the mobile phone terminal unit 31 cannot be turned on without the operation of the power button.

Therefore, the agent module 311 enters the sleep mode to turn off the power after forcibly terminating the running module (app) when the remaining power of the battery falls below the previous standard value when the external power is cut off. do. At this time, the agent module 311 transmits the sleep mode state information to the illegal vehicle tracking server 50, terminates the operation of the remaining modules except the communication module 312, and performs booting for reoperation with the remaining amount of the battery. Ensure sufficient maximum waiting time.

After that, when the external power supply and the external power on signal are received, the agent module 311 turns on the power by the automatic booting function and executes each module (app) to operate the illegal vehicle monitoring function normally. Control it as you can.

In more detail, when the external power supply is resumed in the sleep mode and the remaining battery capacity rises above a predetermined threshold value, the agent module 311 switches the sleep mode to a standby mode and changes its state information. The illegal vehicle tracking server 50 transmits the data. Thereafter, the agent module 311 may operate the mobile phone terminal 31 by automatic booting when a power-on signal is received from the illegal vehicle tracking server 50.

In addition, the agent module 311 sets the system environment to limit unnecessary functions basically installed in the mobile phone terminal 31 and to operate only essential functions necessary for implementing the parking lot access control system.

The agent module 311 acquires OS administrator authority through rooting of the mobile terminal 31, and customizes the camera in the system, license plate recognition function, illegal vehicle determination function, and battery management function through customization. In addition to the operation of the data storage function and the wireless communication function, use of unnecessary functions (app) can be restricted.

As such, the reason why the agent module 311 restricts unnecessary functions is to reduce battery power consumption, prevent collisions due to activation of unnecessary functions, and secure memory to extend system stabilization and endurance life.

For example, unlike the original mobile phone function, the mobile phone terminal 31 does not require the operation of the display (touch screen) when used for access control of the parking lot, so that the agent module 311 always turns off the display. The battery power consumption can be reduced.

The agent module 311 registers the illegal vehicle tracking server 50 interworking with the mobile phone terminal 31 as a master and manages the system environment to operate as a slave.

That is, the agent module 311 provides a control state of the slave mobile phone terminal 31 to the illegal vehicle tracking server 50 as a master through a mirroring screen, and the control command of the illegal vehicle tracking server 50. You can control the system environment. In other words, the illegal vehicle tracking server 50 checks the control state through the mirroring screen of the mobile terminal 31 which is the slave, and operates in the operating state and the standby mode of the mobile terminal 31 remotely through wireless communication. You can remotely control the autoboot function.

The communication module 312 connects wireless communication and wired communication of the mobile phone terminal 31.

The communication module 312 may connect the relay 40 and wireless communication to transmit an event message detected by vehicle number recognition to the illegal vehicle tracking server 50.

In addition, the communication module 312 may receive the vehicle entry signal detected by the loop coil sensor 10 through the power control unit 32 connected through the mobile phone charging terminal (USB cable), the mobile terminal 31 The detected vehicle number may be transmitted to an external device (eg, the building owner's computer OR smartphone) through the power control unit 32 to support the same function as the LPR system in the small parking lot without the LPR system.

In this way, not only the large parking lot equipped with the LPR system but also the small parking lot without the LPR system may provide the vehicle number recognized by the access recognition by simply connecting an external communication device, thereby inducing the installation of the landlord's monitoring terminal 30. .

The location information module 313 serves to generate location information including the ID of the assigned mobile phone terminal 31, GPS information on the currently installed location, and GIS coordinate values, and provide the location information to the illegal vehicle tracking server 50. (I.e., ID + location).

Only one mobile phone terminal 31 may be installed at the parking lot entrance (IN) through which the vehicle enters, but may be installed at the parking lot exit (OUT) to determine that the vehicle is entering. In addition, in the case of a large parking lot, if the entrance or exit is a large area or a multi-storey, such as a multi-storey mobile phone terminal 31 may be additionally installed on the wall or aisle in the parking lot, the terminal ID according to the location installed in the same parking lot Are each given to prevent chaos.

The location information may be generated in conjunction with the GIS coordinates based on the precise GPS information recognized by the location information module 313, and may provide precise sensing location information in which the monitoring terminal 30 is installed.

The camera control module 314 is programmed to be an optimal condition for photographing an entering vehicle and controls the function of the high resolution camera mounted on the mobile phone terminal 31.

At this time, the camera control module 314 may receive a vehicle entry signal from an external loop coil sensor 10 or generate a vehicle entry signal by detecting motion through a motion sensor when the vehicle entry signal is implemented by itself. have.

The camera control module 314 may control size adjustment (eg, resolution adjustment of a stored image), aperture adjustment, focusing adjustment, etc. of the captured image when the vehicle is entered.

The camera control module 314 may be programmed to model and store the shape of the license plate and to focus on the license plate of the entered vehicle.

The vehicle number recognition module 315 analyzes the vehicle image photographed by the camera control module 314 to extract the license plate, and interprets the license plate extracted by the number recognition engine by a character recognition algorithm to recognize the vehicle number.

In this case, the vehicle number recognition module 315 may recognize the vehicle number by extracting the text TEXT from the license plate and detecting letters and numbers matching the text from the stored data. The vehicle number recognition module 315 may be configured in two types, namely, Android or iOS (iPhone OS) to fit the OS of the mobile terminal 31 mounted thereon.

The illegal vehicle determination module 316 stores the illegal vehicle number which is periodically or aperiodically updated from the illegal vehicle tracking server 50 in an illegal vehicle table in the memory. The illegal vehicle table includes vehicle number and illegal matter information (eg, arrears, crime, cannon, etc.), and may further include driver (owner) information and vehicle type (model, color).

The illegal vehicle determination module 316 compares the vehicle number recognized through the number recognition engine with a stored illegal vehicle table to determine whether the illegal vehicle is present according to whether the same number exists.

When the illegal vehicle determination module 316 is determined to be an illegal vehicle because the recognized vehicle number exists in the illegal vehicle table, the illegal vehicle determination module 316 generates an event message according to the illegal vehicle detection and tracks the illegal vehicle through the communication module 312. Can be sent to the server 50.

At this time, the illegal vehicle determination module 316 may generate an event message including the vehicle number, illegal information, terminal ID, location information, shooting time, and captured image of the illegal vehicle.

The illegal vehicle tracking server 50 has a higher control authority operating as a master for the monitoring terminal 30 operating as a slave.

8 is a block diagram schematically illustrating a configuration of an illegal vehicle tracking server according to an exemplary embodiment of the present invention.

Referring to FIG. 8, the illegal vehicle tracking server 50 according to the embodiment of the present invention includes a communication unit 51, a terminal registration unit 52, an illegal vehicle management unit 53, a database 54, and a controller 55. do.

The communication unit 51 includes wired / wireless communication means, and is connected to the monitoring terminal 30 by wireless communication to transmit and receive data for illegal vehicle monitoring and information for management.

In addition, the communication unit 51 collects illegal vehicle information and arrangement release information from a related agency server such as a police station 50a or a tax office 50b connected to the Internet.

The terminal manager 52 matches the terminal ID, GPS, and installed building / parking GIS information of the monitoring terminal 30 distributed in the parking lots for each region to make a DB, and manages an operation state of each monitoring terminal 30.

The terminal manager 52 may collect status information from the monitoring terminal 30 registered in the DB to determine at least one management situation of a normal mode, a sleep mode, a standby mode, and a failure mode. Here, the normal mode is a state in which the external power is applied to monitor the illegal vehicle normally, the sleep mode is a state in which the external power supply is interrupted and the battery level is lower than a predetermined reference value to terminate the monitoring function, the standby mode is the sleep In this mode, the external power supply resumes and waits for restart. In the failure mode, the power of the monitoring terminal 30 is forcibly turned off due to battery discharge after the sleep mode or normal communication is impossible due to a device failure. Each can mean.

When the standby mode information is received from the monitoring terminal 30, the terminal manager 52 may transmit a power-on signal to the monitoring terminal 30 to control the automatic booting function of the agent module 311. .

In addition, the terminal manager 52 may instruct the maintenance work by transmitting the location information of the monitoring terminal 30 to the field worker terminal when the communication of the monitoring terminal 30 is a failure mode.

The illegal vehicle management unit 53 collects illegal vehicle information and arrangement release information from a related agency server such as a police station 50a or a tax office 50b and updates them in real time with the latest illegal vehicle information in the DB 54.

In addition, the illegal vehicle manager 53 may share the illegal vehicle information added and released (deleted) information by transmitting illegal vehicle information updated in the DB 54 to each monitoring terminal 30 at regular intervals.

The database 54 stores various programs and data for operating the illegal vehicle tracking server 50 according to an embodiment of the present invention, and stores data generated according to the operation.

The controller 55 is a central processing unit of the illegal vehicle tracking server 50 according to an embodiment of the present invention, and executes at least one program stored in the DB 54 to control the overall operation of each unit for illegal vehicle tracking. do.

The controller 55 analyzes the event message according to the detection of the illegal vehicle in the monitoring terminal 30 and extracts at least one of the vehicle number, illegal information, terminal ID, location information, shooting time and shooting image of the illegal vehicle. do.

The controller 55 verifies whether the vehicle number included in the event message matches the latest illegal vehicle information updated in real time in the DB 54 and finally determines whether the illegal vehicle is illegal.

When the vehicle number is finally determined to be an illegal vehicle, the controller 55 determines the location information of the illegal vehicle based on the terminal ID included in the event message and the installation location information.

The controller 55 maps the location information of the monitoring terminal 30 in which the illegal vehicle is detected to map information MAP, displays and links the information included in the event message, and transmits the information to the intermittent terminal (not shown). .

Through this, the enforcement unit may be dispatched to the location information of the illegal vehicle to arrest / manage the illegal vehicle and the driver.

However, the controller 55 determines whether the illegal vehicle enters the parking lot entrance IN or the parking position in the parking lot based on the terminal ID or the GPS / GIS MAP-based location information in the process of determining the location information of the illegal vehicle. Or you can find out more if you have entered the parking lot exit (OUT).

For example, the controller 55 may identify ID_IN as entering a parking lot and ID_OUT may be regarded as having exited the parking lot in view of the configuration of the terminal ID assigned to the monitoring terminal 30. In addition, the control unit 55 tracks whether or not the illegal vehicle exists in the parking lot based on the location information of the monitoring terminal 30 installed at the parking entrance (IN) side, the exit (OUT) side, and the wall / ceiling in the parking lot. In consideration of this, it is possible to decide whether or not to start the crackdown. Through this, if it is finally detected that the illegal vehicle has exited to the parking lot exit OUT side, unnecessary dispatch of the enforcement team may be restricted.

On the other hand, based on the configuration of the illegal vehicle tracking system 1 according to the embodiment of the present invention described above, the illegal vehicle tracking method according to the interworking of the monitoring terminal 30 and the illegal vehicle tracking server 50 is shown in FIG. Explain through

9 is a flowchart illustrating a illegal vehicle tracking method according to interworking of a monitoring terminal and an illegal vehicle tracking server according to an exemplary embodiment of the present invention.

Referring to FIG. 9, the monitoring terminal 30 installed at the entrance of the parking lot optimizes the illegal vehicle monitoring function by installing internal hardware and software when power is applied (S1).

At this time, the monitoring terminal 30 may optimize the system by executing each module for detecting the vehicle, photographing the license plate, recognizing the license plate number, and determining whether the vehicle is illegal.

If the illegal vehicle information is received from the illegal vehicle tracking server 50 connected by wireless communication (S2), the monitoring terminal 30 updates the illegal vehicle table stored in the memory (S3).

The monitoring terminal 30 waits for the vehicle to enter the parking lot while the illegal vehicle monitoring function is in operation (S4; No), and when the vehicle entry to the parking lot is detected (S4; Yes), the mobile terminal 31 Shooting with the camera starts.

At this time, the operation method for detecting the vehicle entry to the position where the monitoring terminal 30 is installed is largely two ways, the sensing method using the loop coil sensor 10 or the motion detection of the monitoring terminal 30. Can be applied.

For example, when the roof coil sensor 10 is installed in the parking lot, the vehicle entrance using the same may receive a detection signal from the monitoring terminal 30 to start photographing through a camera. On the other hand, when the loop coil sensor 10 is not installed in the parking lot, the vehicle entrance may be detected and photographing may be started by using a motion detecting technology through an internal camera of the monitoring terminal 30 itself. Operation of the above two methods is almost the same, but whether the vehicle entry detection is recognized by using the external input signal equipped with the vehicle entry detection, or when analyzing the vehicle number by using the motion detecting function of the monitoring terminal 30 itself. It has the same operation algorithm besides the difference of perception.

If it is determined that the surrounding illumination is a night that is less than the threshold (S5; YES), the IR LED light is turned on (S6), and the vehicle is entered through the camera (S7).

On the other hand, if it is determined that the ambient illumination is in the daytime of the threshold or more (S5; no), the monitoring terminal 30 may photograph the vehicle entered through the camera without operating the IR LED lighting (S7).

The monitoring terminal 30 analyzes the photographed vehicle image to extract the license plate, and interprets the license plate extracted through the number recognition engine by using a character recognition algorithm to recognize the vehicle number (S8).

The monitoring terminal 30 compares the recognized vehicle number with the illegal vehicle table to determine whether the vehicle is illegal according to whether the same vehicle number exists (S9).

At this time, the monitoring terminal 30 is mismatched with the illegal vehicle table and determines that it is not an illegal vehicle unless the same vehicle number exists (S9; no), and continues to monitor the next vehicle entry.

On the other hand, the monitoring terminal 30 is matched with the illegal vehicle table (Table) and if the same vehicle number exists, determine that the illegal vehicle (S9; Yes), and generates an event message according to the illegal vehicle detection (S10). In this case, the monitoring terminal 30 may generate an event message including at least one of a vehicle number, illegal matter information, a terminal ID, location information, a shooting time, and a captured image determined as the illegal vehicle.

In addition, the monitoring terminal 30 transmits the event message to the illegal vehicle tracking server 50 connected by wireless communication (S11).

In addition, when the contact information of the control unit terminal in charge of the area installed at the same time as the above is registered, the monitoring terminal 30 can send the event message to the control unit terminal to promptly respond to the monitoring position of the illegal vehicle in the early stage of discovery. .

On the other hand, when the illegal vehicle tracking server 50 receives the event message from the monitoring terminal 30 (S11), the latest illegal vehicle of the DB that is updated in real time from the relevant authority by verifying the vehicle number included in the event message If matched with the information is finally determined as an illegal vehicle (S12).

The illegal vehicle tracking server 50 maps the location information of the monitoring terminal 30 in which the illegal vehicle is detected to map information MAP (S13), and maps the information included in the event message to the map information MAP. The display and link is transmitted to the intermittent terminal (not shown) (S14).

Thereafter, the enforcement unit may drive to the location information of the illegal vehicle displayed on the map information MAP to arrest / manage the illegal vehicle and the driver.

As such, according to an embodiment of the present invention, a monitoring terminal manufactured by recycling inexpensive unused used smartphones is installed at an entrance of a parking lot, and illegal vehicles and their location information which are entered and operated by an unmanned operation are collected and managed in real time from a central location. Providing an intelligent system can reduce the manpower and incidental costs of illegal vehicles.

In addition, by simply mounting the client program (APP) based on the OS of the second-hand smartphone mounted on the monitoring terminal, through this, it is possible to construct an illegal vehicle tracking system at a low cost by managing the operation state centrally.

In addition, by installing the monitoring terminal attached to the breaker or installed on the wall / ceiling of a specific location, the angle for optimizing the vehicle number is optimized, and due to the nature of the parking lot, illegal parking is parked for a certain period of time without moving. Improve your chances of arrest.
