The Bluetooth module 110 may receive a short range wireless communication signal (hereinafter referred to as a Bluetooth signal) from the smart phone 10 through the line L4 of FIG. 1.

The Bluetooth module 110 may be equipped with a 256 Kb memory and a 32-bit ARM CPU. The Bluetooth module 110 may support Bluetooth 4.0 to communicate in the 2.4Ghz frequency band. The Bluetooth module 110 may perform bidirectional communication. The Bluetooth module 110 may further include an acceleration sensor or a temperature sensor. The Bluetooth module 110 may be implemented as, for example, "HBT2X3N".

When the Bluetooth module 110 transmits a Bluetooth signal (eg, beacon signal) containing the ID of the parking lot terminal, the smart phone (example 10) receives the transmitted beacon signal within the reach of the beacon signal. According to an embodiment of the present invention, the smart phone 10 may be equipped with an operating system of Android 4.3 or higher. In addition, the Bluetooth device in the smartphone 10 is in an activated state.

In addition, the smart phone 10 is installed a service application (or app) with a beacon SDK built-in. Therefore, when the smart phone 10 serves as a master, the Bluetooth module 110 of FIG. 2 may serve as a slave. As a result, the Bluetooth module 110 may serve as a beacon output device.

The Bluetooth module 110 and the emergency bell button input unit 160 may be accommodated in the same case 170, but the present invention is not limited thereto. The Bluetooth module 110 is connected to the MCU 120 through a line (L10). The line L10 may be a UART communication line. The MCU 120 is connected to the call circuit 130 and the communication unit 140 through a line L20. The line L20 may be a communication bus.

When the emergency button is pressed, the MCU 120 may recognize an emergency situation by receiving an input of the emergency button. When an emergency occurs, the MCU 120 may output an emergency occurrence signal informing of an emergency occurrence through the communication unit 140. MCU 120 may be implemented using "ATmega128L".

3 is an exemplary configuration block diagram of the smartphone in FIG. 1.

Referring to FIG. 3, the smart phone (Example 10) may include a Bluetooth module 210, a microcontroller unit (MCU) 220, a sensor unit 230, a battery 240, and a button input unit 260. .

The Bluetooth module 210 may transmit a user terminal short range wireless communication signal. The Bluetooth module 210 may support 2.4Ghz Bluetooth 4.0. In embodiments of the present invention, the Bluetooth module 210 may perform unidirectional communication for transmission only. In addition, in the embodiments of the present invention, the Bluetooth module 210 may perform bidirectional communication that performs both transmission and reception of a short range wireless communication signal.

The Bluetooth module 210 may communicate with the Bluetooth module 110 of FIG. 2. The Bluetooth module 210 may provide a vehicle number of the vehicle 1 or residence location information of the user to the Bluetooth module 110.

The smartphone 10 of FIG. 3 may perform the parking position recognition by receiving beacon signals transmitted from the Bluetooth module (eg 110) of the parking terminal group 100 after the start time of the parking position recognition is determined.

The Bluetooth module 210 of the smart phone 10 may transmit a beacon signal including the ID of the smart phone as a near field wireless communication signal after the start time of the parking position recognition is determined. Therefore, the Bluetooth module 110 of FIG. 2 may receive the beacon signal transmitted from the Bluetooth module 210 within the reach of the beacon signal.

In FIG. 3, the sensor unit 230 may include at least one of an acceleration sensor, a geomagnetic sensor, and a gyro sensor. The acceleration sensor may also include a function of detecting gravity acceleration.

The acceleration sensor is a sensor that detects activity information of the smart phone user, such as movement or walking. The acceleration sensor detects the increase / decrease ratio of speed for linear movement in any direction to detect the movement of the smartphone user. As a result, the acceleration sensor outputs the magnitude of the acceleration applied to the object.

A 3-axis acceleration sensor with a sensing range of x, y, and z directions can measure acceleration in three-dimensional space. That is, the movement of the object may be detected based on the inclination angle of the object and the acceleration in each direction based on the gravity acceleration. Earth's gravity is 1G in the vertical direction. Therefore, the tilted state of the object and the ground direction are detected by the detection of the acceleration of gravity. As a result, gravity acceleration can be used to detect the vehicle getting off of the smartphone user.

Geomagnetic sensor is a sensor for detecting the flow of magnetic field generated from the earth. Geomagnetic sensors can be used to detect a bearing like a compass. Geomagnetic sensors are used to detect the direction of movement of the smartphone user. Geomagnetic sensors use the Earth's magnetic field to detect azimuth. The three-axis geomagnetic sensor includes sensors that detect the strength of the magnetic field in the X, Y, and Z directions. Once the output vector sum of the sensors is calculated, the direction of movement of the object is measured.

Gyro sensor is a sensor for detecting the rotational inertia of an object. The gyro sensor is an angular velocity sensor that detects a value of an angle of rotation of an object in unit time with respect to one axis. The gyro sensor can detect whether an object (here, a smartphone) moves left or right or up or down. When an object moves, Coriolis forces are generated. Using this formula, Coriolis forces can be used to detect the angular velocity acting on the inertial system. In general, MEMS (Micro Electro Mechanical System) gyro accuracy is 10 ~ 100 deg / hr, if the sensor signal processing well can be used as 1deg / hr. The 1deg / hr class means that the posture changes by 1 degree for 1 hour when there is no input. Precision compensation of the gyro sensor may be implemented by the acceleration sensor.

After parking the vehicle, the smart phone user may get off the vehicle and start walking. The walking cycle of a smartphone user is defined as the time interval between two consecutive identical events that occur for the same foot while the user walks. The walking cycle consists of two phases: the step phase, when the foot contacts the ground, and the swing phase, where the foot moves off the ground and moves on to the next step. An event that occurs at the start of a stepping step is called a heel strike, and an event that occurs at the start of a turning step (or at the end of a stepping step) is called a heel off.

Logically, the gravitational acceleration of the user's body is local max at heel strike and local min at heel off during the user's walking cycle. In other words, if one user touches the ground while the other foot is in contact with the ground (heel strike), the gravitational acceleration is maximal. Then, if one foot falls off the ground (heel off) while the other foot hits the ground, the gravitational acceleration is minimal. This phenomenon occurs similarly when the user runs. In other words, if the user steps down the ground with the other foot (heel strike) while one foot is in the air, the gravitational acceleration is maximal. Then, if one foot in the air touches the ground and the other foot falls off the ground (heel off), the gravitational acceleration becomes minimal.

As a result, two adjacent pairs of points immediately before the gravitational direction acceleration becomes maximum and immediately after the gravitational direction acceleration become minimal correspond to one step. Accordingly, the use of consecutive maximum-minimum peak pairs of gravitational acceleration may determine the user's start of blackness and the number of steps. Therefore, the starting point of the parking position recognition in the present invention can be obtained from the process of determining the number of steps of the user based on the maximum-minimum peak of the one-dimensional sequence with respect to the gravity direction acceleration.

An example of a method for searching for a continuous maximum-minimum peak is disclosed in Korean Patent Publication No. 10-2016-0109712, which was invented by the inventor Kwon Yong-jin and published on September 21, 2016, and a method for controlling a terminal providing a pedometer function. Terminal ".

The sensor unit 230 applies a movement detection signal to the MCU 220 as activity information when the smartphone user is in a walking state after getting off the vehicle.

The MCU 220 may calculate, for example, the moving direction and the moving distance of the smart phone user based on the sensor value (or measured value) of the gyro sensor, the sensor value of the acceleration sensor, and the sensor value of the geomagnetic sensor. The MCU 220 may grasp the up, down, left, and right movements of the smart phone user or the smart phone from the sensor value of the gyro sensor. The sensor value of the acceleration sensor is used to determine the moving distance over time. The sensor value of the geomagnetic sensor is used to determine the direction in which the smartphone user moves. The grasp of the travel distance can be more accurately calculated using the sensor value of the acceleration sensor and the RSSI.

The MCU 220 may determine when the activity information after parking of the user, that is, the movement detection signal is received, through the sensor unit as a starting point of the parking position recognition. Meanwhile, the MCU 220 may retroactively determine the first starting point of the movement as the starting point of the parking position recognition when the smart phone user moves a certain distance. For example, in the case of the operation of the pedometer, no indication is made on the display until the user moves about three steps. Then at the moment the user moved 4 steps the pedometer displays the number "4". Similarly, in an embodiment of the present invention, after detecting a user's walking at a certain distance, a determination about a starting point of parking location recognition may be retroactively applied.

In addition, the MCU 220 may determine a start point of the parking position recognition by using a walking navigation algorithm using a step detection technique, a stride length estimation technique, or a progress direction estimation technique.

The MCU 220 may transmit a user terminal short range wireless communication signal when a start time of parking position recognition is determined. On the other hand, when the start point of the parking position recognition is determined, the MCU 220 transmits the short range wireless communication signals received from the parking lot terminal group 100 as a valid signal for parking position recognition without transmitting a short range wireless communication signal to the user terminal. Can handle As a result, the MCU 220 may determine when the activity information of the smart phone user having the smart phone 10 is detected as a start point of the parking position recognition. Activity information of the smart phone user may be detected by analyzing the detection signals provided from the sensor unit 230 embedded in the smart phone 10.

The button input unit 260 may be used to control various control operations of the smart phone 10, for example, set, reset, on, or off.

4 is a timing diagram illustrating a parking position communication signal of the smart phone 10 in FIG. 1.

Referring to FIG. 4, section ⓐ represents a reception possible section of the Bluetooth module of the smartphone, and ⓑ represents a reception OFF section of the Bluetooth module of the smartphone. In the OFF period of the Bluetooth module, the Bluetooth module of the smart phone is turned off and does not receive a beacon signal. Ⓓ represents a transmission section of the beacon signal, ⓔ represents a transmission waiting section of the beacon signal. Ⓕ indicates the transmission period of the beacon signal. Thus, k indicates that reception of the beacon signal is valid, and k indicates that reception of the beacon signal is invalid.

The waveform ① shows the operation timing of the Bluetooth reception cycle of the smartphone. ② shows the case where the beacon signal is received in the middle of the receiving section. ③ shows the case where the beacon signal is received at the end of the reception interval. ④ shows the case where the beacon signal is received at the beginning of the reception section, and waveform ⑤ shows the case where the beacon signal is received at the start of the reception section. In the case of ②, ③, and ④, the beacon signal is effectively provided to the smartphone. Meanwhile, in the case of ⑤, the beacon signal received at the end of the reception period may be treated as valid.

The reception timing of FIG. 4 may be implemented by setting or changing an application program mounted on the smart phone.

5 is an exemplary view showing parking position communication modes of the smart phone of FIG. 1. Referring to FIG. 5, parking position communication modes may be divided into first, second, and third modes. In the first mode, the ON period of the Bluetooth module 110 is shorter than that of the second mode. For example, the on period of the first mode may be 1/10 second, and the on period of the second mode may be 1/5 second. Therefore, the power consumption of the first mode is less than that of the second mode. In the third mode, the on period of the Bluetooth module 110 is longer than that of the second mode. For example, the on period of the third mode is 1/2 second. Therefore, the power consumption of the third mode is higher than that of the second mode. In the third mode, the information is started. Information disclosure may mean transmitting a beacon signal through the Bluetooth module 210.

In the case of Figure 5, the parking position communication modes are divided into three modes, but this is only an embodiment and the present invention is not limited thereto.

As described above, the smart phone 10 may determine the starting point of the parking position recognition. When the start time is determined, the smart phone 10 may transmit a short range wireless communication signal to the user terminal. Finally, the smart phone 10 may function as an element that directly or indirectly recognizes a parking position.

In addition, the smart phone 10 communicates with the parking lot terminal (Example 101) so that the parking lot terminal (Example 101) of FIG. 1 functions as a parking lot identification unit. That is, the parking lot terminal 101 may obtain the vehicle number of the vehicle 1 or the residence location information of the user through communication with the smart phone 10.

6 is a diagram illustrating a near region in a parking lot according to an embodiment of the present invention.

Referring to FIG. 6, the parking lot 202 may be divided into a near region 204 and a normal region 206 based on the entrance and exit 302. When the number of parking surfaces is 150, for example, parking surfaces 1 to 30 may be included in the near area 204. Meanwhile, parking surfaces 31 to 150 may be included in the normal area 206. The near area 204 is set based on the entrance and exit 302 and may vary according to circumstances.

7 is a diagram illustrating a setting near area in a parking lot according to another embodiment of the present disclosure.

Referring to FIG. 7, the parking lot 202 may be divided into a set near area 204 and a normal area 206 regardless of the entrance and exit 302. When the number of parking surfaces is 150, for example, parking lots 12 to 25 may be determined as the setting near area 204 by the user's setting. Meanwhile, parking surfaces 1 to 11 and 26 to 150 may be included in the normal area 206. The setting near area 204 may be designated by the user's setting regardless of the entrance and exit 302. For example, in the case of an electric vehicle, if the charging connector is installed on the parking surfaces 12 to 25, the parking surfaces 12 to 25 may be the set near area 204.

FIG. 8 is an exemplary view illustrating lighting / flashing of parking surfaces and a parking lot induction lamp of a parking lot applied to FIGS. 6 and 7.

Referring to FIG. 8, a plurality of parking surfaces PA1-PA12 are partitioned in the parking lot 202, and a parking position identification unit (Example B1B1) is provided for each parking unit of three units. The plurality of parking position identification units B1A1-B1A3 and B1B1-B1B3 serve as coordinates for identifying parking positions in the parking lot. The parking terminal (Example 101) of FIG. 1 may be provided for each of the plurality of parking position identification units B1A1-B1A3 and B1B1-B1B3 or part of them. Therefore, the parking lot terminal 101 has a unique terminal ID for the operation of the parking position.

In FIG. 8, for example, only two parking surfaces PA5 and PA6 in the parking lot 202 are empty without the vehicle MC1 being parked. In this case, if the two parking surfaces PA5 and PA6 belong to the near area or the near home area, the man-vehicle induction lamp installed near the first camera CA1 is turned on or blinks to induce near parking.

Manhole car induction lamp may be included in the parking guide. Manhole car guide lamps may be displayed in a different color than normal manhole car guides for near parking guidance. For example, if the tolerance is displayed in green when inducing normal parking, the tolerance may be displayed in orange or yellow when inducing near parking. The display of color may be implemented using the inherent light emission color of the light emitting diode.

The first camera CA1 may be installed on the raceway RA together with the second camera CA2. The first and second cameras CA1 and CA2 may function as a parking surface manager that manages whether each of the parking surfaces in the parking lot 202 is full or empty due to a vehicle parked previously.

The first camera CA1 monitors whether the six parking surfaces PA1-PA6 have empty cars. Meanwhile, the second camera CA2 monitors whether the six parking surfaces PA7-PA12 have empty cars. When performing parking plane management using cameras, the sensor unit corresponding to each parking plane may be removed.

The parking guidance unit preferentially finds a parking surface PA5 or PA6 corresponding to a near area for providing convenience to a user of the vehicle when the vehicle guides the vehicle entering the parking lot to one of the empty parking surfaces. .

If there is no parking surface corresponding to the near area, normal normal parking guidance may be performed. Normal parking guidance means to guide a vehicle to an empty parking surface within a parking lot.

9 is a view provided to explain parking guidance using a smart phone and a guide display panel according to an embodiment of the present invention.

Referring to FIG. 9, a vehicle user may receive a parking guidance service of a near area or a near home area through a screen of the smart phone 10. In this case, the map of the parking lot is displayed on the smart phone 10, and an induction route for parking guidance may be displayed.

In addition, the vehicle user may receive a parking guidance service for the near area or the near home area through the guide display board 280. The parking state is displayed on the screen 282 of the guide display panel 280, and the lighting / flashing state of the manhole vehicle induction lamp 284 is also shown. Therefore, the vehicle user can drive the vehicle to preferentially park to the near area or the near home area.

When the vehicle user enters the parking lot, the color of the man-vehicle guidance lamp 284 provided near the first camera CA1 of the parking surface manager 200 indicates that the near area or the near home area exists. Accordingly, the vehicle user may attempt to park on the empty parking surface while checking the color of the manhole vehicle induction lamp 284.

Upon completion of parking, the full vehicle guidance ramp 284 is turned off or displayed in a color indicating fullness.

10 is a flowchart of the parking guidance control according to an embodiment of the present invention.

Referring to FIG. 10, in operation S610, the parking guidance unit 400 checks whether vehicle entry exists. The vehicle entry check may be implemented by receiving a vehicle entry signal from the vehicle identification unit 150, the entrance beacon device 250, or the parking lot terminal (eg, 101).

In operation S620, the parking guide part 400 obtains a vehicle number. Acquisition of the vehicle number may be implemented by receiving vehicle number information provided from the vehicle identification unit 150. Acquisition of the vehicle number may be implemented by receiving customer information / resident information or vehicle number information provided from the parking lot terminal 101.

In operation S630, the parking guidance unit 400 checks whether the vehicle is a near area target vehicle. The parking guidance unit 400 may check whether the vehicle that is entered is a vehicle that is subject to a near area parking guidance service based on the vehicle number or residence information. The parking guide unit 400 may operate a parking surface management table as shown in FIG. 12.

In operation S640, the parking guidance unit 400 searches for user information corresponding to the entry vehicle. The parking guidance unit 400 searches for user information (usually driver information) through the parking surface management table.

In operation S650, the parking induction part 400 checks whether a near area parking surface exists. The presence of the near area parking surface is confirmed by receiving parking surface full vehicle information through the parking surface management unit 200.

If the near area parking surface exists, in operation S660, the parking induction part 400 controls the man-vehicle induction lamp to the near area induction mode. Accordingly, the manhole difference induction lamp installed near the camera CA1 of FIG. 8 displays a color indicating near area parking induction.

On the other hand, if the near area parking surface does not exist, in operation S670, the parking guidance unit 400 controls the man-vehicle guidance lamp in the normal induction mode.

In operation S680, the parking induction unit 400 checks whether parking completion has been performed. Performing the parking completion can be achieved by parking location recognition via the smart phone (10).

When parking completion is performed, in operation S690, the parking guidance unit 400 controls the man-vehicle guidance lamp to display the color of the parking completion state. In this case, the color of the parking completion state may be displayed in red. In another case, the parking vehicle induction lamp may be turned off in the parking completion state.

The near area control service of FIG. 10 may be suitable for inducing parking of public buildings, such as department stores.

11 is a flowchart of a parking guidance control according to another embodiment of the present invention.

Referring to FIG. 11, in operation S710, the parking guidance unit 400 checks whether vehicle entry exists.

In operation S720, the parking inducing unit 400 may receive a wireless communication signal provided from the smart phone 10 through the parking lot terminal 101. In another case, the parking guidance unit 400 may receive vehicle number information through the vehicle identification unit 150.

In operation S730, the parking guidance unit 400 obtains a vehicle number through the vehicle identification unit 150 or the parking lot terminal 101.

In operation S740, the parking guide part 400 checks whether the vehicle is a near home object.

In operation S750, the parking induction unit 400 searches for lake number information of the apartment house corresponding to the entry vehicle. For example, 112-507 corresponds to 57-ma6473 vehicle in the table of FIG.

In operation S760, the parking guide part 400 checks whether a near home parking surface exists.

If the near home parking surface exists, in operation S770, the parking guidance unit 400 controls the man-vehicle induction lamp in the near home induction mode.

If the near home parking surface does not exist, in operation S780, the parking induction part 400 controls the man-vehicle induction lamp in the normal induction mode.

In operation S790, the parking inducing unit 400 checks whether parking completion has been performed.

When the parking completion is performed, in operation S792, the parking guidance unit 400 controls the man-vehicle guidance lamp to display the color of the parking completion state.

Meanwhile, when the vehicle is parked, the manhole vehicle guidance lamp may be turned off based on the manhole vehicle management of the parking surface manager.

In addition, when the vehicle is parked, the man-vehicle guidance lamp may be turned off based on the parking position recognition of the parking lot terminal 101.

12 is an exemplary view of a parking surface management table applied to FIG. 11.

Referring to FIG. 12, the residence information corresponding to the vehicle number and the area setting of the parking surface are shown in the parking surface management table. For example, the residence information corresponding to vehicle number 57M6473 is 112-507. In the case of the vehicle, since the near home area is not set separately, the near home area may be selected as the automatic mode. Therefore, the number of parking surfaces corresponding to the near home area is set from 1 to 30.

Vehicle number 57M6473 When the vehicle enters the parking lot, if the number of empty parking surfaces in the near home area is 16 or 17, the near home parking guidance may be directed to the 16 parking surface. If the vehicle is departed after the vehicle has been parked, the withdrawal check mark on parking side 16 becomes "0". When the exit check mark becomes "0", parking side 16 becomes an empty parking side again.

In this case, the near home area is set to parking lots 12 to 25 by the user of 112-510. Vehicle number 57M6473 If the vehicle is not parked after parking, the parking check mark on parking side 16 is "X". When the exit check mark is "X", parking side 16 becomes the full parking side.

In addition, there is no empty parking surface in the near home area when the vehicle No. 32H6162 enters the parking lot. In this case normal induction is performed.

13 is a flowchart of providing parking position recognition that can be linked with the parking guidance of the present invention.

In operation S610, the smart phone (for example 10) checks whether the user of the smart phone 10 is in the vehicle.

In operation S620, the smartphone 10 may switch the operation mode from the first mode of FIG. 5 to the second mode. That is, the smart phone 10 may switch the operation mode for the Bluetooth communication to the second mode when the vehicle is in the vehicle. As a result, when the smart phone user rides in the vehicle, the Bluetooth module 110 may be turned on every 1/5 second which is the on cycle of the second mode. The smart phone 10 may operate in the second mode when the smart phone user rides in the vehicle.

Checking the vehicle boarding may be performed by the user manually operating the smart phone 10 or the smart phone 10 may automatically perform the check operation of the vehicle boarding. In the case of automatically performing the check-in operation of the vehicle, the smartphone 10 detects the detection signals of the sensor unit 230 of FIG. 3 based on whether the GPS signal and the short-range wireless communication signal of the parking lot terminal group 100 are received. Can be analyzed. That is, when entering a parking lot for parking, a GPS signal is received, but a short range wireless communication signal of the parking lot terminal group 100 is not received. In addition, analyzing the detection signals of the sensor unit 230 of FIG. 3 may detect the operation of the vehicle.

In operation S630, the smartphone 10 may only check whether a beacon signal is received from the entrance beacon device 250. The complex entrance here refers to the entrance to a common house such as an apartment complex. A beacon device 250 that transmits a beacon signal may be installed at the entrance of the apartment complex to facilitate the parking position operation operation.

If a beacon signal is received from the only entrance beacon device 250 when the vehicle passes only the entrance, in operation S640, the smartphone 10 may secure parking lot related map information. Securing the parking lot-related map information may be implemented by the web server receiving the parking lot-related map data by the smart phone 10. On the other hand, irrespective of this, parking lot-related map information, for example, parking lot map data, may be stored in advance in the smart phone 10 through downloading.

In operation S650, the smartphone 10 may switch the operation mode from the second mode to the third mode. The third mode is a mode in which information disclosure can be performed.

The operations S610 to S650 are exemplary and the present invention is not limited thereto. That is, operations S610 to S650 may be omitted as necessary.

In operation S660, the smart phone 10 determines the starting point of the parking position recognition using the sensor unit 230 of FIG. That is, the smart phone 10 detects whether the smart phone user started walking after parking.

As such, the starting point of the parking position recognition may be determined when the activity information of the smart phone user is detected. Activity information of the smart phone user may be detected by analyzing information provided from a sensor (eg, an acceleration sensor) embedded in the smart phone.

The beacon signals transmitted from the parking lot terminals 101-105 of the parking lot terminal group 100 are treated as valid signals for performing the parking position recognition after the start time of the parking position recognition is determined.

In operation S670, the smartphone 10 searches for a signal having the largest signal strength among the beacon signals received from the parking lot terminals 101-105. The smartphone 10 may detect the received field strength (RSSI) of the beacon signals, and process the detected received field strength (RSSI) by a triangulation algorithm. Accordingly, the smart phone 10 may recognize the location of the parking lot terminal (Example 101) located closest to the smart phone.

The smartphone 10 may display the installation area of the parking lot terminal (Example 101) as the parking position on the parking lot related map information. That is, when the parking position is displayed on the map of the parking lot, the user may check the parking position through the display screen of the smart phone 10. In addition, the parking position data may be stored in the smart phone 10 in the form of a message or text.

When the web server is installed in FIG. 1, the recognized parking position information may be transmitted to the web server by the smart phone 10. The web server may transmit the recognized parking position information to a parking guidance device or a home network server. The home network server may be connected with an elevator call controller and / or generation wall pad. Accordingly, the parked user can automatically call the elevator without pressing the elevator call button. That is, the user calls the elevator only by the parking behavior of the vehicle itself. The wall pad is installed for each generation and can communicate with the home network server. Therefore, the parking position information may be displayed on the monitor screen of the wall pad.

As another example, when the web server is installed, the performing agent for recognizing the parking position may vary. That is, in operation S670, the smart phone 10 receives a plurality of beacon signals and delivers them to the web server. The web server finds the beacon signal having the strongest signal strength among the received beacon signals. The web server may measure the received field strength (RSSI) of the beacon signals, respectively, and process the measured field strength (RSSI) by a triangulation algorithm. Accordingly, the web server can recognize the location of the parking terminal (Example 101) installed closest to the smart phone 10 as the parking position. The web server may transmit the recognized parking location information to the smart phone 10 through 3G, 4G, 5G, or Wi-Fi network.

Therefore, the smart phone 10 can display the installation area of the parking lot terminal (Example 101) as a parking position on the map of the said parking lot. In addition, the smart phone 10 may store the installation area of the parking terminal 101 as parking location information. In this case, the user can know the parking position of the vehicle by checking the message of the smart phone 10.

On the other hand, when there is no web server, the parking guidance unit 400 communicating with the parking terminal group 100 may be the subject of parking location recognition. In operation S670, the smart phone 10 which is disembarked with the user in the parked vehicle is unique every predetermined period through the Bluetooth module 110 after determining the starting point of the parking position recognition using the sensor unit 230 of FIG. 3. The signal may be transmitted as the user terminal short range wireless communication signal.

The unique signal may be in the form of a beacon signal as described above. In this case, the parking lot terminals 101-105 receive the beacon signal as the user terminal short range wireless communication signal. In this case, the parking terminal (101) located closest to the smart phone 10 will receive the beacon signal of the smart phone 10 at the strongest electric field strength.

The parking lot terminals 101-105 transmit beacon signals of the received smart phone 10 to the parking induction unit 400, respectively. The parking induction unit 400 may measure the received field strength (RSSI) of the beacon signals, respectively, and process the measured received field strength (RSSI) by a triangulation algorithm. Accordingly, the parking induction unit 400 may recognize the location of the parking lot terminal (example 101) that received the strongest beacon signal of the smart phone 10 as the parking position. The parking induction unit 400 transmits the recognized parking position back toward the parking terminals 101-105. The parking lot terminals 101-105 apply the recognized parking position information to the smart phone 10.

Therefore, the smart phone 10 can display the installation area of the parking lot terminal (Example 101) as a parking position on the map of the said parking lot. In addition, the smartphone 10 may store the installation area as parking location information in the form of text. As a result, even in this case, the user can check the parking position through the display screen of the smart phone 10.

Meanwhile, the smart phone 10 transmits the user terminal short-range wireless communication signal through the Bluetooth module 110 after determining the starting point of the parking position recognition, but the present invention is not limited thereto.

For example, after the smart phone 10 determines the starting point of the parking position recognition, the smart phone 10 may receive the Bluetooth signal of the parking lot terminal group 100 and then transmit the short-range wireless communication signal to the user terminal. That is, two-way communication is performed between the smart phone 10 and the parking lot terminal group 100.

In operation S680, the smartphone 10 checks whether the beacon signals provided from the parking lot terminal group 100 are below a set reception sensitivity. If the beacon signals transmitted from the parking lot are below the set reception sensitivity or are not received, the user's smart phone 10 may be said to be out of the parking lot. As a result, operation S690 is executed when the beacon signals are below the set reception sensitivity.

In operation S690, the smartphone 10 may switch the operation mode from the third mode to the first mode. Accordingly, the battery consumption of the smart phone 10 in the first mode will be significantly reduced compared to the case of the third mode.

Since the low power communication is basically supported in the case of a communication specification of Bluetooth 4.0 or higher, the mode switching may be selectively performed only when necessary. Such switching of the operation mode is merely exemplary, and the present invention is not limited thereto.

Parking location recognition using the smart phone as described above may be fused with the near home parking guidance of the present invention.

The Bluetooth module 110 functions as a wireless signal reader. The Bluetooth module 110 may obtain a vehicle number of the vehicle 1 or residence location information of the user by receiving a radio signal transmitted from the smart phone 10. Therefore, the parking lot terminal 102 including the Bluetooth module 110 also serves as a parking identification unit.

On the other hand, the emergency bell button input unit 160 may be installed on the wall surface of the parking lot. When the emergency bell provided in the emergency bell button input unit 160 is pressed, an emergency signal is wirelessly transmitted.

The MCU 120 may recognize the occurrence of an emergency situation by receiving the emergency signal transmitted wirelessly. The MCU 120 may apply an emergency signal to the communication unit 140.

As a result, the first and second camera modules 1100 and 1200 used in the embodiment of the present invention are much more compact in size than the general camera recognition camera module or CCTV camera module.

The first and second camera modules 1100 and 1200 and the Bluetooth module 210-1 may be combined in one component unit and installed in the raceway 181.

The controller 2000 receives a first image from the first camera module 1100. The controller 2000 receives a second image from the second camera module 1200. The controller 2000 may convert the first and second images and output the first and second images for each channel.

The controller 2000 may be implemented with, for example, "ASC8852A" which is a processor for a high resolution security camera. In addition, the controller 2000 may extract a still cut, that is, a still image, to be used for vehicle number recognition from the first and second images. The still image may be transmitted through one channel of the plurality of channels.

The image processor 3000 is connected to the controller 2000. The image processor 3000 may receive the first and second images and the still image. The image processor 3000 may process or compress the first and second images and the still image. Accordingly, the transmission efficiency of the image data transmitted can be increased.

The communication unit 4000 is connected to the image processing unit 3000. The communication unit 4000 receives image data of the image processing unit 3000 through a line I / O. The communication unit 4000 outputs the received image data to the transmission line. Here, the transmission line may be a TCP / IP communication line for Ethernet communication. In addition, the transmission line may be a wireless communication channel.
