Hereinafter, some embodiments of the present invention will be described with reference to the drawings.

1 is a configuration diagram of a system for performing a method of returning a shared bicycle equipped with a locking device according to an embodiment of the present invention.

Referring to FIG. 1, a system for returning a shared bicycle equipped with a locking device may include a bicycle locking device 100 and an operator terminal 200 attached to a bicycle to be locked. However, this is only a preferred embodiment for achieving the object of the present invention, and of course, some components may be added or deleted as necessary. Hereinafter, for convenience of description, the bicycle lock device 100 will be referred to as a'lock device'.

The locking device 100 is a device that is attached to a bicycle to be locked to perform a locking or unlocking operation on the bicycle to be locked, and is a device in which a hardware and/or software prevention design for an abnormal locking problem is implemented. In FIG. 1, the lock device 100 is illustrated as being attached to a front wheel wheel of a bicycle to be locked. However, if the movement of the bicycle to be locked can be restrained, the attachment position of the locking device 100 may be varied as much as possible. In addition, depending on how the locking device 100 restrains the movement of the bicycle to be locked, the locking device 100 may be implemented to be removable. In this case, the attachment position of the locking device 100 may be changed by the operator of the bicycle to be locked.

The locking device 100 may automatically perform a locking operation or an unlocking operation in response to a locking event or an unlocking event according to a specified condition. For example, a lock event or a unlock event may occur according to a command of the operator input to the operator terminal 200. As another example, when an operator's lock command or unlock command is input to an input device provided in the lock device 100, a lock event or a unlock event may occur. In addition, conditions for generating the lock event or the unlock event may vary. However, the scope of the present invention is not limited to specific conditions.

In this embodiment, the locking device 100 determines in real time the driving state of the bicycle to be locked. In addition, if it is determined that the bicycle to be locked is in the current driving state, the locking operation is not performed even if a locking event occurs. This is because the locking operation during driving can be a great threat to the safety of the driver. For the same reason, the locking device 100 does not perform a locking operation even if it is determined that the bicycle to be locked is in a pause state while driving.

The operator terminal 200 is a computing device carried by a driver of a bicycle to be locked. As illustrated in FIG. 1, the computing device may be, for example, a handheld device such as a smart phone, but is not limited thereto.

According to some embodiments of the present invention, the operator terminal 200 may provide the driving information or return information input by the operator to the locking device 100. The operation information may include, for example, a place of departure, a destination, and the like, and the return information may include, for example, a return time and a place for return. The driving information and the return information may be used for the purpose of performing locking by the locking device 100. This will be described later.

In this embodiment, the locking device 100 and the operator terminal 200 may communicate through a network. For example, the network may be implemented with all types of wireless networks, such as Bluetooth and a wireless local area network (LAN). However, the scope of the present invention is not limited thereto.

So far, referring to FIG. 1, a system for performing a method of returning a shared bicycle equipped with a locking device according to an embodiment of the present invention has been described.

Next, a configuration of a system according to another embodiment of the present invention will be described. Referring to FIG. 2, a system for returning a shared bicycle equipped with a locking device may further include a server 300. Using the server, the service provider can remotely control the locking device to perform a method of returning the bicycle to be locked.

The configuration and operation of the locking device 100 according to the embodiment of the present invention will be described with reference to FIGS. 3 to 7.

3 is a block diagram showing a locking device 100 according to another embodiment of the present invention.

Referring to FIG. 3, the locking device 100 includes a storage unit 110, a sensor unit 120, a power supply unit 130, a lock prevention unit 140, a lock operation unit 150, a communication unit 160, and a control unit ( 170). However, only components related to the embodiment of the present invention are illustrated in FIG. 3. Therefore, it can be seen that a person skilled in the art to which the present invention pertains may include other general-purpose components in addition to the components shown in FIG. 3.

Looking at each component, the storage unit 110 is the sensing data measured by the sensor unit 120, the lock status information analyzed by the lock status analysis unit 178 to be described later, the operation received from the operator terminal 200 Various data such as information may be temporarily or non-temporarily stored. In particular, the storage unit 110 may store at least one program or application for performing a shared bicycle return method according to an embodiment of the present invention.

The storage unit 110 includes a flash memory type, a hard disk type, a solid state disk type, an SDD type (Silicon Disk Drive type), and a multimedia card micro type. type), card type memory (e.g. SD or XD memory, etc.), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable EEPROM and a storage medium of at least one type of read-only memory (PROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk. However, in addition to the above example, the storage unit 110 may include a computer-readable recording medium in any form well known in the art.

The sensor unit 120 measures the driving state of the bicycle to be locked in real time, and outputs sensing data regarding the driving state. The sensing data is used by the driving state determination unit 176, which will be described later, to determine in real time the driving state of the lock target bicycle.

According to an embodiment of the present invention, the sensor unit 120 may be configured to include a plurality of sensors 120a to 120n as shown in FIG. 4. That is, the sensor unit 120 may output various sensing data measured by the plurality of sensors 120a to 120n. Therefore, even if a measurement error is included in some sensing data, since the driving state determination unit 176 can determine the current state of the bicycle to be locked using some other sensing data, the accuracy of the driving state determination may be improved. In addition, reliability of the sensor unit 120 and/or the locking device 100 may also be improved. For reference, the measurement error may be caused by various reasons, such as when a measurement value is not output from some sensors or when circuits of some sensors are broken.

The plurality of sensors 120a to 120c may be composed of different types of sensors, and at least some of the sensors may be configured of the same type of sensors. That is, the first sensor 120a and the second sensor 120b may be composed of different types of sensors, or the same type of sensors may be configured. As such, the type and number of sensors included in the sensor unit 120 may vary depending on the embodiment.

Examples of the sensors included in the sensor unit 120 may include an acceleration sensor, a gyro sensor, a geomagnetic sensor, a magnetic sensor that detects rotation of a bicycle wheel, a position sensor such as a pressure sensor, GPS, and an image sensor such as a camera. Can.

Depending on the embodiment, some of the sensors included in the sensor unit 120 may be positioned independently of the locking device 100. For example, in the case of a sensor equipped with a wireless communication function, the measurement may be spaced apart from the locking device 100 for accuracy. For a more detailed example, the pressure sensor may be installed on the saddle of the bicycle to be locked to accurately determine whether the driver is on board, and the locking device 100 may be installed spaced apart from the position illustrated in FIG. 1.

In addition, according to an embodiment, a part of the sensing data that the locking device 100 collects to determine the current state of the bicycle to be locked may be collected by the operator terminal 200. For example, the locking device 100 may receive the sensing data measured by the sensor provided in the operator terminal 200 to determine the current state of the bicycle to be locked.

According to an embodiment of the present invention, the plurality of sensors 120a to 120c included in the sensor unit 120 may be formed as a plurality of sensor groups by the control unit 170. In addition, the state of the bicycle to be locked can be individually determined using the sensing data measured by each sensor group. For example, the first state of the bicycle to be locked may be determined using the sensing data measured by the first sensor group, and the second state of the bicycle to be locked using the sensing data measured by the second sensor group. Can be judged. The detailed description of this embodiment will be described later with reference to FIG. 7. For reference, the sensor group may include at least one sensor, and the sensor group may be logically formed such that at least one sensor included in each sensor group is a different sensor.

Referring back to FIG. 3, the power supply unit 130 applies or blocks power to each component constituting the locking device 100 in response to a control signal from the power control unit 174 to be described later. To this end, the power supply unit 130 may include a battery for supplying power and a switch that provides a power supply and shutdown function.

The lock operation unit 140 performs a lock operation or a unlock operation on the bicycle to be locked in response to a control signal from the lock control unit 172, which will be described later. As described above, the manner in which the locking operation unit 140 physically restrains the movement of the bicycle to be locked through the locking operation may be any method.

The lock prevention unit 150 physically blocks the lock operation of the lock operation unit 140 in response to a control signal from the lock control unit 172. If the locking operation can be physically blocked, the lock prevention unit 150 may be implemented in any form.

According to an embodiment of the present invention, the lock prevention unit 150 may be implemented to be circuitly separated from the lock operation unit 140. Accordingly, even if the lock operation unit 140 malfunctions due to an incorrect control signal, the lock prevention unit 150 can block the malfunction of the lock operation unit 140 without being affected by this, and the reliability of the shared bicycle return function is reliable. This can be further improved. For the same reason, it may be desirable for the lock prevention unit 150 to be provided with a power cutoff module that performs a power supply and cutoff function separately from the lock operation unit 140.

According to an embodiment of the present invention, the lock prevention unit 150 may be implemented to circuitly detect the lock operation of the lock operation unit 140. For example, it is implemented in a circuit so that the switch can be turned on or off according to the locking operation of the locking operation unit 140, and the locking prevention unit 150 may be implemented to detect the state of the switch. In addition, the locking prevention unit 150 may be implemented in any way as long as it can detect the locking operation.

In the present embodiment, while the lock target bicycle is in the driving state, when the lock operation of the lock operation unit 140 is detected, the lock prevention unit 150 locks the operation even if a lock blocking signal is not input from the lock control unit 172 It may be implemented to block the locking operation of the unit 140.

The communication unit 160 supports wired/wireless communication of the locking device 100, and can transmit and receive various information with an external device. The communication unit 160 may be provided with information, such as driving information and/or lock prevention information, to perform a method according to an embodiment of the present invention from an external device, for example, the operator terminal 200. In addition, the communication unit 160 may receive user input regarding various selections and commands from the operator terminal 200, and may transmit various processing results in response to the user input to the operator terminal 200.

For example, the communication unit 160 is a Bluetooth communication unit, a Bluetooth Low Energy (BLE) communication unit, a near field communication unit (Near Field Communication unit), a WLAN (Wi-Fi) communication unit, a Zigbee communication unit, an infrared (IrDA, infrared data association) A communication unit, a WFD (Wi-Fi Direct) communication unit, a UWB (ultra wideband) communication unit, an Ant+ communication unit, and the like may be included, but is not limited thereto.

The control unit 170 controls the overall operation of each component of the locking device 100. The control unit 170 may include a CPU (Central Processing Unit), an MPU (Micro Processor Unit), an MCU (Micro Controller Unit), or any type of processor well known in the art. The control unit 170 may also include a memory, for example, a RAM. Also, the control unit 170 may store at least one application or program for executing a method according to an embodiment of the present invention.

For example, the controller 170 may store and execute a shared bicycle return program according to an embodiment of the present invention. When the control unit 170 executes the shared bicycle return program, the shared bicycle return method according to an embodiment of the present invention may be performed.

Specifically, in order to perform the method for returning a shared bicycle according to an embodiment of the present invention, the control unit 170, as shown in Figure 5, the lock control unit 172, the power control unit 174, the driving state determination unit 176 ) And the locked state analysis unit 178.

The lock control unit 172 controls the lock operation or the unlock operation of the lock operation unit 140 in response to a lock event or a unlock event according to a specified condition. Specifically, the lock control unit 172 controls the unlock operation of the lock operation unit 140 by outputting a lock release signal when a lock event occurs according to a specified condition, and a lock signal when a lock event occurs according to a specified lock condition To control the locking operation of the locking operation unit 140.

According to an embodiment of the present invention, the lock control unit 172 may not output a lock signal even if a lock event occurs according to the determination result of the driving state determination unit 176.

For example, the driving state determining unit 176 may determine a pause state during driving based on the locking state of the locking device 100. That is, the locked state of the lock device 100 analyzed by the locked state analysis unit 178 may be utilized to determine a pause state while driving. When it is determined that the vehicle is temporarily stopped while driving, the current state of the lockable bicycle is determined to be the driving state, and the lock control unit 172 may not output a lock signal even if a lock event occurs. According to the present exemplary embodiment, an abnormal locking operation may be prevented while driving, and a bicycle accident due to the abnormal locking may be prevented.

In addition, in some embodiments of the present invention, even if a lock event occurs according to the determination result of the lock state determination unit 178 in the lock control unit 172, the lock signal may not be output. It will be described with reference to FIG. 6.

When the lock state determination unit 178 is composed of a plurality of lock state determination units 176a to 176n as illustrated in FIG. 5, it is determined that at least one lock state determination unit 176a to 176n does not satisfy the lock condition. If it does, the lock control unit 172 may hold the output of the lock signal during the lock hold signal.

In addition, according to an embodiment of the present invention, even if a lock event occurs and it is determined that the bicycle to be locked is in a stopped state by the driving state determination unit 176, the lock control unit 172 outputs a lock signal during the lock hold time. Can be withheld. In the present embodiment, the lock control unit 172 may output a locked lock signal only when the stationary state of the lock target bicycle is maintained during the lock hold time. According to this embodiment, the lock control unit 172 detects an additional state change during the lock hold time and strictly controls the lock operation, so that the reliability of the automatic lock function provided by the lock device 100 is more reliable. Can be improved.

The lock hold time may be a preset fixed value, or may be a variable value that fluctuates depending on the situation.

In one embodiment, the communication unit 160 may receive the driving destination information of the bicycle to be locked input to the operator terminal 200 by the operator. In addition, the control unit 170 may adjust the lock hold time based on the received information. Specifically, the lock hold time may vary depending on the distance between the current location of the bicycle to be locked and the driving destination. For example, when the distance between the current position of the bicycle to be locked and the driving destination is within a preset distance, the lock holding time may be updated to a smaller value than before. This is because if the driver has reached the driving destination, there is a high probability that the bicycle to be locked will be parked.

In addition, according to an embodiment of the present invention, when the occurrence of a lock event is detected while a condition such as the time corresponding to the return condition time or entering a location around the return condition place is satisfied, the operator terminal 200 ) To provide a notification according to the occurrence of the lock event. In this case, whether or not to perform the locking operation may be determined according to the operator's selection.

The power control unit 174 controls power application and shutdown for each component included in the locking device 100. Specifically, the power control unit 174 outputs a power supply application signal or a power supply shutdown signal to the power supply unit 130 to control power supply and shutdown for each component.

According to an embodiment of the present invention, as the unlocking signal is output by the locking control unit 172, the power control unit 174 may output a power cutoff signal to cut off the power of the locking operation unit 140 to the power supply unit 130. Can. According to this embodiment, it is possible to prevent the locking operation unit 140 from abnormally operating due to an incorrect control signal or noise on the circuit during driving.

The driving state determination unit 176 determines whether the bicycle to be locked is in a running state, a stopped state, or a temporarily stopped state while driving using the sensing data regarding the driving state measured by the sensor unit 120.

According to an embodiment of the present invention, in order to improve the accuracy of the driving state determination, the driving state determination unit 176 may be configured to include a plurality of driving state determination units. In addition, each driving state determination unit may perform driving state determination for the lock target bicycle based on sensing data measured by each sensor group.

On the other hand, since the operator may temporarily stop the bicycle for various reasons while the bicycle is running, the driving state determining unit 176 needs to distinguish the stationary state from the temporary state during driving.

In one embodiment, the driving state determining unit 176 may detect whether the driver is on board or not by using a pressure sensor attached to the saddle of the bicycle to be locked, and determine a pause state during driving based on the driving state. For example, even if a change in sensing value is not observed by an acceleration sensor, a gyro sensor, etc., if the pressure value measured by the pressure sensor is greater than or equal to a threshold value, the driving state determination unit 176 pauses while the bicycle to be locked is driving You can judge that

In one embodiment, the driving state determination unit 176 may detect the left and right inclination of the lock target bicycle by using a tilt sensor, and determine a pause state during driving based on the sensing state. Here, the tilt sensor may be configured of any sensor as long as it can measure the left and right tilt of the bicycle to be locked. For example, the tilt sensor may include a gyro sensor, an acceleration sensor, and the like, and a tilt calculation algorithm well known in the art may be incorporated by reference herein.

In this embodiment, the driving state determining unit 176 may determine that the locking target bike is in a pause state while driving, when the left and right slopes of the locking target bike measured by the tilt sensor are less than a preset threshold. . This is because there is a very low probability that a bicycle in a running state or in a paused state while driving is laid over a certain angle. Here, the threshold value may be a preset fixed value or a variable value adjusted according to the driving pattern of the driver. In addition, the threshold value may be set by the operator through the operator terminal 200.

The locked state analysis unit 178 may analyze the locked state of the operator based on the sensing data measured by the sensor unit 120 and the history of performing the lock stored in the storage unit 110. Here, the lock state may include, for example, a lock position at which the lock operation was performed, a time at which the lock operation was performed, a distance between the position at which the unlock operation was performed, and the position at which the lock operation was performed, or a time at which the unlock operation was performed. It may include a time difference between the time at which the lock operation is performed, a speed pattern, and the like.

More specifically, the lock status analysis unit 178 may analyze the history of performing the lock and derive the location and time at which the lock operation is performed more than a predetermined number of times as lock status information. In FIG. 7, it is assumed that the lock status determination unit 178 includes only the first lock status determination unit 178a, the second lock status determination unit 178b, and the third lock status determination unit 178c.

Referring to FIG. 7, the first lock state determination unit 176a may determine the first state of the bicycle to be locked based on the sensing data measured by the first sensor group 121, and determine the second lock state The unit 176b may determine the second state of the bicycle to be locked based on the sensing data measured by the second sensor group 122. Similarly, the third lock state determining unit 176c may determine the third state of the bicycle to be locked based on the sensing data measured by the third sensor group 123.

As illustrated in FIG. 7, each sensor group 121, 122, and 123 may include only one sensor or may include a plurality of sensors. In addition, although FIG. 7 shows that one sensor belongs to one sensor group as an example, according to an embodiment, the one sensor may belong to a plurality of sensor groups.

In this embodiment, the plurality of locked state determination units 176a to 176c provide a plurality of state information determined based on sensing data measured by different sensor groups. Also, as described above, the lock control unit 172 may strictly control the lock operation in consideration of all of the plurality of state information. For example, the lock control unit 172 may operate to output a lock signal only when all of the plurality of state information indicates a stop state.

Meanwhile, in the above-described embodiment, it has been described that the lock control unit 172 controls the lock operation in consideration of all of the plurality of state information determined by the first to third lock state determination units 176a to 176c. However, according to another embodiment of the present invention, the lock control unit 172 may control the lock operation in consideration of only some state information.

For example, when an abnormality is detected in a sensor included in the first sensor group 121 through a periodic built-in test, the lock control unit 172 may determine the second and third driving states 176b , 176c), the lock operation may be controlled.

As another example, the accuracy scores of each of the first to third lock status determination units 176a to 176c are calculated, and the lock control unit 172 is based only on the determination results of the two lock status determination units having the relatively high accuracy scores. The locking operation can be controlled. Likewise, if there are n lock status determination units, the lock control unit 172 may use only the determination result of the top k (where k is a natural number of 1 or more and n or less) based on the accuracy score. Here, the accuracy score can be given in various ways. For example, the same initial score is assigned to each lock state determination unit, the accuracy state is further assigned to the lock state determination unit that derives a relatively accurate state determination result, and the driving state derives a relatively inaccurate determination result. The determination unit may calculate the accuracy score by subtracting the accuracy score. At this time, whether the determination result is relatively accurate or inaccurate may be determined based on the determination result derived from the majority of lock status determination units. For example, when the majority of the lock state determination unit determines that the lock state is the stop state, the lock state and the pause state during driving may be determined as a result of a relatively inaccurate judgment.

Meanwhile, a method of determining a locked state of each locked state determining unit may also vary according to a type of sensor included in each sensor group. This will be briefly described as an example.

For example, when the first sensor group includes at least one of an acceleration sensor, a gyro sensor, and a geomagnetic sensor, the first lock state determination unit changes the sensing data measured by the first sensor group for a predetermined time. When is greater than or equal to the threshold, it may be determined that the bicycle to be locked is in a driving state. Here, the threshold value may be a preset fixed value or a variable value adjusted according to the driving pattern of the driver. In addition, the threshold value may be set by the operator through the operator terminal 200.

As another example, when the second sensor group includes a magnetic sensor that is mounted on the wheel of the bicycle to be locked to detect the rotation of the wheel, the second lock state determination unit detects the rotation of the wheel by the second sensor group If it is, it can be determined that the bicycle to be locked is in a driving state.

As another example, if the third sensor group includes a position measurement sensor for measuring the position of the bicycle to be locked, the third driving lock determination unit detects a change in the position of the bicycle to be locked by the third sensor group, It can be determined that the bicycle to be locked is in a running state.

As another example, when the fourth sensor group includes an image sensor for photographing the surrounding image of the bicycle to be locked, the fourth lock state determination unit may detect the change in the surrounding image by the fourth sensor group, and then lock the image. Target bicycle It can be determined that the bicycle is in a driving state.

Using the above-described lock state information, the lock state determination unit 178 may accurately determine a pause state during driving.

In one embodiment, even if the driving of the lock target bike is not sensed in the sensing data, the lock state determining unit 178 has a distance between the lock position included in the lock state and the current position of the lock target bike equal to or greater than a preset distance. In this case, it may be determined that the lock target bicycle is in a pause state while driving. This may be understood as using a high probability that the target bicycle is re-parked around a parking place or a favorite place frequently used by bicycle operators.

So far, some embodiments have been described in which the lock state determination unit 178 determines the pause state while driving using the lock state information. The locked state determination unit 178 may determine the state of the bicycle to be locked according to any one of the several embodiments described above, and a combination of some embodiments may cause the locked target bike to pause while driving. You can also decide if you are in. Meanwhile, although not illustrated, the locking device 100 may be configured to further include an input unit (not shown) and a display unit (not shown).

The input unit (not shown) receives various data, commands, and/or information from the operator. In particular, the input unit (not shown) may receive information about a command indicating a locking operation or unlocking of the locking device 100 from the operator. The input unit (not shown) may include any type of input means well known in the art.

The display unit (not shown) displays various data, commands, information, and/or GUIs to the user. Specifically, the display unit (not shown) may display lock state information of the lock device 100, driving information calculated based on sensing data, and the like. The display unit (not shown) may include any type of display means well known in the art.

The locking device 100 may include at least some of the above-described components. That is, not all of the above-described components are essential components of the locking device 100, and the locking device 100 may be configured by excluding some components.

Each component of FIGS. 3 to 7 may mean software or hardware such as a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). However, the above components are not limited to software or hardware, and may be configured to be in an addressable storage medium, or may be configured to execute one or more processors. The functions provided in the above components may be implemented by more detailed components, or may be implemented as a single component that performs a specific function by combining a plurality of components.

So far, the configuration and operation of the locking device 100 according to an embodiment of the present invention have been described with reference to FIGS. 3 to 7, but those skilled in the art will describe in detail with reference to FIGS. 3 to 7. It will be clearly understood that embodiments of the present invention can also be referred to as a shared bicycle return method, which will be described later. Next, a method for returning a shared bicycle according to another embodiment of the present invention will be described in detail with reference to FIGS. 8 to 15.

Hereinafter, each step of the method for returning a shared bicycle according to an embodiment of the present invention may be performed by the operator terminal 200 controlling the locking device 100 unless otherwise specified. However, for convenience of description, description of the subject of the operation for performing each step may be omitted. In addition, each step of the shared bicycle return method may be an operation performed by the operator terminal 200 by executing the shared bicycle return program by the operator terminal 200.

8 is a system configuration diagram of a method for returning a shared bicycle according to an embodiment of the present invention

Referring to FIG. 8, when the state of the bicycle to be locked is recognized as a normal locked state rather than a lock while driving through the lock device 100, unique identification information (eg QR code) is displayed through the display unit attached to the locked target bike. Is displayed. As the locking device 100, a locking device described with reference to FIGS. 3 to 7 may be used. However, it is not limited thereto.

The operator terminal 200 recognizes this and transmits it to the server 300. The server 300 determines whether the location of the bicycle to be locked corresponds to a designated return location or the locked state of the bicycle to be locked based on identification information of the bicycle to be locked.

If all the criteria are satisfied, the server 300 may activate the return button of the operator terminal 200. It will be described in detail through FIGS. 9 to 14 below.

9 is a flowchart of a shared bicycle return method that may be performed in response to a lock event. However, this is only a preferred embodiment for achieving the object of the present invention, and of course, some steps may be added or deleted as necessary.

In step S100, a lock event is received. Referring to FIG. 10, it is determined in step S101 whether the vehicle is locked while driving. When the vehicle is temporarily stopped while driving, a lock pending signal is output in step S102. This is to prevent accidents while driving by increasing the accuracy of judgment on the lock event.

If it is determined in step S101 that the lock event is not a pause while driving, it is requested to receive identification information in step S103. The identification information refers to identification information unique to the bicycle to be locked. The identification information may be an image or a unique number. For example, the identification information may be a QR code or a barcode assigned to each bicycle.

9, the first state is determined in step S200. The first state refers to whether the bicycle is located at a designated return location or place.

Referring to FIG. 11, it is determined whether the return position is designated in step S201. This is because the return should be made only when the bicycle is located at a designated location or location (virtual station) for returning the non-mounted shared bicycle. The virtual station may be arbitrarily designated by a service provider or may be designated or automatically generated on a map according to specific conditions. You may not be able to return it only at locations or locations that you have set in reverse.

For example, the designated location may be a location where a bicycle has already been returned in the vicinity. At this time, when the operator terminal scans the surrounding lock device and there is a lock device other than the lock device attached to the bicycle to be locked, a virtual station may be created. At this time, the GPS embedded in the driver's terminal or the locking device may be used to determine whether it is a designated location.

If it is not the designated return position, it is led to the designated return position in step S202. For example, in the case of attempting to return at a position that cannot be returned, the state indicator attached to the lockable bicycle can be guided to move by displaying the most possible position along with the notty that the return is not possible. At this time, the status indicator may be changed along with the notifies that the location is continuously checked by using the GPS and returned when it is possible to return.

In addition, in a non-returnable position, the speaker embedded in the locking device may continuously display an alarm sound or may be displayed in a different color according to the state by using the LED embedded in the locking device.

Referring to FIG. 9 again, the second state is determined in step S300. This will be described in detail with reference to FIG. 12. First, it is judged in step S301 whether it is possible to judge the return condition. If it is not possible to determine the return condition, in step S303, photography and transmission of the locked bicycle and surrounding pictures are induced.

For example, when such a situation is detected by a sensor or the like, the normal return mode is automatically changed to a photo shooting mode. In the photographing return mode, a photograph is automatically taken and transmitted to the server even when the return button of the operator terminal is pressed.

There are various methods for more accurately grasping the surrounding situation in the photography return mode. For example, in a general situation, if the QR code attached to the A portion of the bicycle to be locked is set to be returned, if a specific situation is detected, the code attached to the B portion is photographed to be returned to be returned. . At this time, the code mounted on the B part can be coded only when the user is further away from the bicycle to be locked, and the surrounding situation will be naturally photographed.

Alternatively, in the photographing and returning mode, the operator terminal may recognize the bicycle by image recognition so that it can be returned. In this case, machine learning may be used for image recognition.

As another example, a specific pattern may be put in the bicycle to be locked so that the bicycle to be locked is recognized through a camera. The image may be analyzed based on the specific pattern to determine whether the lockable bicycle satisfies the return condition.

If it is possible to determine the return condition in step S301, it is determined whether the return condition is satisfied in step S302. The return conditions may include whether the bicycle is lying down, indoors, whether there is no damage.

For example, by using a temperature sensor built into the locking device, it can be classified into indoor and outdoor, so that it cannot be locked indoors. Alternatively, in the case of a temperature that differs by more than a threshold value compared to room temperature, locking may be impossible.

When the bicycle to be locked is an electric bicycle, the return condition may be satisfied only when the electric bicycle is recognized as being charged. This is to check whether the electric bicycle is properly charged because the next user has no inconvenience in using the electric bicycle.

The case of being recognized as being charged means a case where the position of the bicycle to be locked is the location of a bicycle charging station or it is confirmed that the battery pack of the electric bicycle has been charged through the sensor of the locking device.

The condition may be determined through image analysis using the photographed picture. Alternatively, it may be determined through sensor data generated while driving the bicycle to be locked.

If the return condition is not satisfied, it is induced in step S304 to satisfy the return condition.

For example, if the return condition determination is made through sensor data, and the impact level of the lockable bicycle is measured, if a shock greater than a reference value is generated while driving, it may be induced to be photographed.

Referring to FIG. 9 again, when both the first state and the second state are satisfied, the return button is activated in step S400. That is, if the bicycle to be locked is not in a designated position through the first state determination, payment is not made and returns are not made even if a payment request is made through the payment equipment connected to the bicycle or the lock target. Similarly, if the bicycle to be locked is not in a normal state through the determination of the second state, payment is not made even if a payment request is made through the payment device connected to the bicycle or the lock target, and no return is made.

If the user leaves the bicycle without attempting to return it, if it is a returnable location, it is automatically locked and returned, but in the case of a non-returnable location, the operator terminal until the lock is performed remotely and returned to the specified location In the notty can continue to be received. At this time, the operator may apply for remote return by paying an additional fee through the operator terminal.

13 to 14 are exemplary views of a screen of the operator terminal 200. Hereinafter, a screen showing a returnable position will be described with reference to FIGS. 13 to 14.

Referring to FIG. 13, a return location search function is being executed through the display unit 220 of the operator terminal. First, the user can input the origin 221 and the destination 222. 13, a home address (Seongnam-si, Gyeonggi-do) is entered as a departure point 221, and a company address (Seongnam-si, Gyeonggi-do) is entered as a destination 222.

When the setting of the starting point 221 and the destination 222 is completed, the predicted route map 223 is displayed. At this time, the returnable location may be displayed together. This will be described in detail with reference to FIG. 14.

14, returnable locations 2231 and 2232 are also displayed on the predicted route map 223. The return locations 2223 and 2232 may be changed according to surrounding environment, time, weather, and user. By analyzing the surrounding environment, time, weather, and user data, it is possible to automatically adjust the number and conditions of locations that can be returned. This will reduce the service provider's workload and reduce management costs.

That is, a return location of the bicycle may be managed according to a specific situation by displaying different returnable locations for each bicycle or user. For example, different returnable locations may be displayed for each inspection cycle. These conditions have the effect of facilitating management by collecting bicycles with similar inspection cycles.

Alternatively, users with high creditworthiness may show more returnable locations, thereby increasing the usability of the bicycle by creditworthiness.

In addition, it is possible to limit the number of bicycles that can be returned to one returnable location. In this case, if the number of bicycles that can be returned exceeds, the location may not be displayed. In addition, the number of bicycles that can be returned may be written together on the map in Arabic numerals. In FIG. 14, seven bicycles are currently available for returning at position 1 2223, and four are available for returning position 2 2232.

The concept of the present invention described so far with reference to FIGS. 1 to 14 may be embodied as computer readable code on a computer readable medium. The computer-readable recording medium may be, for example, a removable recording medium (CD, DVD, Blu-ray Disc, USB storage device, removable hard disk), or a fixed recording medium (ROM, RAM, computer-equipped hard disk). Can. The computer program recorded on the computer-readable recording medium may be transmitted to another computing device through a network such as the Internet and installed on the other computing device, and thus used on the other computing device.

Although the operations are shown in a specific order in the drawings, it should not be understood that the operations must be performed in a specific order or in a sequential order, or all illustrated operations must be executed to obtain a desired result. In certain situations, multitasking and parallel processing may be advantageous. Moreover, the separation of various configurations in the above-described embodiments should not be understood as such a separation is not necessarily necessary, and the described program components and systems may generally be integrated together into a single software product or packaged into multiple software products. It should be understood that there is.
