2, the bicycle theft prevention apparatus 100 includes a communication unit 110, a sensor unit 120, a main control unit 130, a power source unit 140, and an input / output unit 150 ).

The communication unit 110 generates current location information of the bicycle anti-theft device 100 and transmits current location information to the smart device of the user when the theft occurs.

Also, the communication unit 110 performs data communication with the smart device and SMS transmission function, and transmits a theft occurrence message to the smart device when a theft occurs.

In addition, the smart device is a general term for mobile devices capable of wireless communication such as a smart phone and a tablet PC.

The communication unit 110 includes a broadband wireless communication module 111, a location information reception module 112, and a short-range wireless communication module 113.

Also, the broadband wireless communication module 111 connects to a broadband wireless communication network (WCDMA network, LTE network) and transmits / receives data to / from the smart device through a telephone communication network.

The broadband wireless communication module 111 includes an internal location information receiving device 111a that is connected to a communication company's base station and performs an A-GPS (Assisted-GPS) function and an MS-based GPS (Mobile Station-based GPS) ).

In addition, the A-GPS function requires acquiring at least four pieces of satellite information in order to determine the current position in the GPS module (112, GPS module) using the network assisted GPS function. However, when the A-GPS function is used, Satellite information from the neighboring base stations, it is possible to acquire the satellite information and obtain the satellite information to determine the current position.

In addition, the A-GPS function continuously utilizes the secondary satellite even in an environment where it is difficult to continuously acquire more than four satellites due to disturbance of the radio wave environment such as a building densely populated area, .

In addition, the MS-based GPS function serves to shorten the time to first fix (TTFF) of four satellites at the time of initial positioning by a network interworking positioning shortening function, The time error between the satellite and the receiver, and the time error between the satellite and the receiver.

The position information reception module 112 receives the latitude and longitude values from the satellite and calculates a positional correction error value received from the DGPS (Differential GPS) reference station, Accurate positioning function is performed by correcting the error value.

The main control unit 130 determines whether the bicycle is stolen according to the signal detected by the sensor unit 120 and transmits the current position information to the smart device from the communication unit 110 when the theft occurs.

The main control unit 130 integrally controls the functions of the communication unit 110, the sensor unit 120, the power unit 140, and the input / output unit 150.

The power supply unit 140 supplies power to the communication unit 110 and the main control unit 130.

The power supply unit 140 may include a battery 141 for charging or discharging power or a charging / discharging unit for charging the battery 141 with external power or converting the charging power of the battery 141 into primary power, And a voltage conversion module 143 for converting the primary system power to the secondary system power and supplying the secondary system power to the communication unit 110 and the main control unit 130.

The power conversion unit 143 converts the voltage of the power source to a secondary system power source that is an operation power of the communication unit 110 and the main control unit 130 because the power source unit 140 receives a power of 5V through a USB port It serves as a supplier.

The input / output unit 150 turns on / off the operation of the main control unit 130 and the power supply unit 140 or supplies external power to the power supply unit 140.

The input / output unit 150 transfers data input from the outside to the main control unit 130 or outputs data from the main control unit 130 to the outside.

The input / output unit 150 includes a power switch 151, a function operation switch 152, a first USB port 153, a second USB port 154, a buzzer 155, a status display LED 156 And a function setting switch 157.

The power switch 151 allows the primary system power to be output from the charge / discharge module 142 to the voltage conversion module 143, and the voltage conversion module 143 is connected to the main control unit 130 And the secondary system power of the voltage conversion module 143 is supplied to the communication unit 110 under the control of the main control unit 130. [

That is, the power switch 151 serves to efficiently use the power charged in the battery 141 by supplying or cutting off power to the entire apparatus.

In addition, the function operation switch 152 allows the power to be supplied from the power supply unit 140 to the main control unit 130).

In addition, the function operation switch 152 has substantially the same function as the magnetic sensor 123.

The first USB port 153 applies external power to the charge / discharge module 142 or transmits / receives data to / from the main control unit 130.

That is, the first USB port 153 is a port that can also serve as data transmission / reception and charging.

Also, the second USB port 154 applies external power to the charge / discharge module 142 and is used for charging only.

However, the second USB port 154 is only an example of the components constituting the input / output unit 150, and is not necessarily included.

The buzzer 155 is connected to the main control unit 130 and generates a buzzer sound when the main control unit 130 receives the buzzer generation signal.

In addition, the buzzer 155 may output a burglar alarm output during theft and a function-completed buzzer sound output when the specific function is performed.

The status LED 156 may indicate a charged state of the power supply unit 140 or a functional operation state of the main control unit 130.

In addition, the status LED 156 may be a multicolor LED, and the color or lighting method may be different depending on the state of charge or function.

The function setting switch 157 serves to set whether the main control unit 130 operates by the magnetic sensor 123 or the function operation switch 152 in the initial operation.

This is to prevent the non-user from initially operating the bicycle anti-theft device of the present invention.

Hereinafter, a bicycle theft prevention method according to an embodiment of the present invention will be described in detail with reference to FIG.

In addition, the method for preventing bicycling according to an embodiment of the present invention is performed through the bike anti-theft device 100 and the user's smart device.

First, when the power switch 151 of the input / output unit 150 is turned on (S1000) and the mode of the function setting switch 157 is switched to the function operation switch mode The main control unit 130, the acceleration sensor 121 and the gyro sensor 122 are activated (S1200) if there is an input of the function operation switch 152 (S1120).

However, when the function setting switch 157 is set to the magnetic key mode, when the magnetic sensor 123 senses the magnetic key, the main control unit 130, the acceleration sensor 121 and the gyro sensor 122 are activated (S1200).

That is, since the initial activation method can be determined according to the setting of the user, the use of others can be restricted.

Next, the main control unit 130 causes the power supply unit 140 to apply power to the communication unit 110, and the broadband wireless communication module 111, the position information reception module 112, The operation of the controller 113 is started (S1300).

At this time, the status LED 156 is flickered, and the user can be notified of the initial startup status.

In addition, the acceleration sensor 121 and the gyro sensor 122 may be started first in the case of the wideband wireless communication module 111 of the communication unit 110 in about 50 seconds for interlocking with the network, The initial response may fail.

The modules of the communication unit 110 are preferably operated in the order of the near field wireless communication module 113, the location information receiving module 112, and the wideband wireless communication module 111.

As described above, in the case of the wideband wireless communication module 111, when it takes a certain time to interwork the network and the network congestion occurs, it is difficult to transmit SMS messages or data communication. Therefore, And communicates with the smart device through communication.

Next, the communication unit of the user's smart device and the communication unit of the bicycle anti-theft device 100 are interlocked with each other through the network (S2000), and the communication unit 110 generates current position information and transmits the current position information to the main control unit 130.

Also, the current position information can be precisely obtained through the DGPS function. Acquisition of the positional information has been described above, and a detailed description thereof will be omitted.

Next, theft monitoring begins.

However, if the power switch 151 is turned off during the theft monitoring, it returns to the start step (S2000).

When the magnetic sensor 123 or the operation switch 152 is detected during the theft monitoring (S2200), the main control unit 130 checks the operating state of the buzzer 155 (S2400) (S2500), and then returns to the start step.

That is, after the operation is started, the function of the apparatus is stopped when a signal is inputted from the magnetic sensor 123 or the function operation switch 152 again.

For example, when the magnetic sensor 123 detects the magnetic key for 3 seconds or more, or when the function operation switch 152 is pressed for 3 seconds or more, the function can be stopped.

After the start of the operation, the thief may contact the magnet sensor 123 or press the function operation switch 152 to stop the function, so that the user can operate the magnetic sensor 123 and the function The function of the operation switch 152 can be stopped.

For example, when the main control unit 130 receives the function stop command of the magnetic sensor or the function operation switch from the smart device of the user (S2100), if the function stop command is not received from the smart device (S2300) The functions of the main control unit 130 and the communication unit 110 are maintained without stopping even when there is an input to the sensor 123 and the function operation switch 152. [

When the function stop command is received from the smart device (S2300), the main control unit 130 determines whether the operation state of the buzzer 155 (S2400), stops the operation of the modules of the communication unit 110 (S2500), and returns to the start step.

However, if there is no function stop command from the smart device and there is a buzzer on / off command (S5000), the buzzer sound is stopped (S5100), a buzzer sound is generated (S5200) If there is a stop command of the position information receiving module 112 or the wideband wireless communication module 111 in step S5300, the corresponding function is stopped in step S5400.

If the current time is not the wakeup time preset by the smart device (S5500), the function is automatically stopped without a separate function stop command (S5600)

In addition, the steps S5100, S5400, and S5600 may be inserted at any stage of the entire process without a preceding step.

Next, when theft monitoring is started, the main control unit 130 detects vibration and tilting in the sensor unit 120 (S3000), and if vibration occurs for a predetermined time (for example, 5 seconds) And recognizes the occurrence of a theft, and generates a strong burglar alarm through the buzzer 155 (S3200).

Next, the main control unit 130 determines whether the local area wireless communication module 113 and the smart device are interlocked with each other to perform local area wireless communication (S3300). If local area wireless communication is possible, (S3400).

However, if short-range wireless communication is not possible, a thief occurrence message is transmitted to the smart device through the broadband wireless communication module 111 (S3500).

Next, the current location information is transmitted to the smart device (S3700).

If the current position information is not generated, the communication unit 110 generates the current position information (S3600).

Next, if there is no additional movement (S4000), if the vibration does not occur for a predetermined time (S4010), it is determined that the occurrence of theft is canceled and the process returns to the step of starting the theft monitoring.

However, if vibration is generated for a predetermined period of time, the main control unit 130 generates a buzzer sound through the buzzer 155 (S4020) ).

Next, if an additional location movement occurs, the location change message is transmitted to the user's smart device (S4100).

In addition, the message transmission method is classified into a direct communication method, an indirect communication method, and a method combining direct communication and indirect communication. Direct communication is a method of transmitting an SMS message directly to a telephone number of a smart device such as an SMS transmission, The communication method is a method in which the message data is first transmitted to the data server in the Internet protocol manner and the data server transmits the message data to the smart device. In the method of direct communication and indirect communication, the battery capacity and communication environment are checked, And indirect communication is selectively used.

Next, the main control unit 130 transmits current position information to the smart device at predetermined time intervals.

However, when a message is continuously transmitted in the same phone number (terminal ID), the smart device recognizes the received message as a spam message and blocks the reception, so that only when there is a location information transmission command from the smart device S4300) The current location information can be transmitted.

Next, the smart device generates a tracking route using the current position of the bicycle received from the bicycle anti-theft device 100 as a starting point and the location information of the smart device as a destination, and displays the tracking route on the electronic map.

In addition, the tracking path is updated and output when the updated current position information is received from the bicycle anti-theft device 100. [

4, the current position of the smart device at time t1 is S1, the current position of the bicycle is D1, and the tracking path is P1.

Next, the user moves to the current position of the bicycle along the tracking path P1. When the current position D2 of the updated bicycle is received at time t2, a tracking path P2 between the current position S2 of the smart device and the D2 is generated and displayed on the electronic map do.

Next, the user moves to the position of the bike along the tracking path P2, and when the current position D3 of the bicycle born at the time t3 is received, the tracking path P3 between the current position S3 of the smart device and the D3 is generated and displayed on the electronic map .

This process is repeated so that the user can catch the bicycle thief at the tracking path P4.

In addition, the smart device of the user is provided with an electronic map in which a tracking path is displayed, as well as an operation state indicating a battery state, a buzzer state, a sensor state, a connection state of a broadband wireless communication module, A display window, a message status display window indicating whether the message reception method is a direct communication method or an indirect communication method, a status information reception status display window displaying reception status of status information, and the like, An electronic map control window can be popped up which can set environment such as accumulation and direction.

Next, the main control unit 130 checks the battery state of the power source unit 140 (S4500), determines whether the battery charging power source is an operable power source (S4600), and if not, (S4610), transmits the location information transmission disabled message to the smart device, and terminates (S4620).

However, if the battery state of the power source unit 140 is the operable power source, the battery information is transmitted to the smart device (S4700), and further the process returns to step S4200 of monitoring whether the positional change occurs.

3, the steps S4500, S4600, and S4700 of checking the battery status and transmitting battery information are performed after the theft occurs. However, after the start of the bicycle theft prevention method of the present invention, .

Therefore, according to the bicycle anti-theft device and method of the present invention, the accurate current position of the bicycle can be actively generated, and the generated current position information and various messages can be indirectly communicated, It is possible to transmit without failure by using indirect communication and direct communication, and it is advantageous for the recovery of the stolen bicycle because the tracking route can be continuously updated using the updated location information.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation in the present invention. Various changes and modifications will be possible.
