The magnetic contact sensor 120 can sense whether the pedal 17 is rotating or not. The magnet contact sensor 120 can generate an output signal when the reed switch 120a and the magnet 120b are paired and the reed switch 120a and the magnet 120b are brought close to each other. The magnet contact sensor 120 may be mounted on the body frame 14 and the pedal 17 on which the saddle 12 of the bicycle 10 is installed.

The optical sensor 130 may sense the rotation of the wheel 11. [ The optical sensor 130 is a sensor that outputs light and senses a reflected object in a forward direction. The optical sensor 130 may be mounted on a wheel frame connecting the main body frame 14 and the wheel 11 so as to output light toward the wheel 11. [ At this time, the wheel 11 may be provided with a circular plate 500 including a plurality of absorption regions 500a and reflection regions 500b. Accordingly, the optical sensor 130 outputs light toward the circular plate 500 rotating according to the rotation of the wheel 11, and can sense light reflected from the circular plate 500.

The clock sensor 140 may measure the time. The clock sensor 140 may be zs-042 as a real-time clock sensor, for example.

The Wi-Fi beacon 150 is a module that enables Wi-Fi communication of the safety device 1000 for a bicycle. The Wi-Fi beacon 150 may scan an AP signal installed nearby to record the SSID value and the RSSI value.

The GPS sensor 160 can confirm the real-time position of the bicycle 10. [ The GPS sensor 160 may obtain the latitude and longitude values for the current position of the bicycle 10. [

The switch sensor 170 can detect whether or not the occupant 11 is in contact with the saddle 12 or the both knobs 13. [ The switch sensor 170 may be a sensor that generates an output signal when a pressure is applied and the switch is closed. The switch sensor 170 can be mounted on the saddle 12 and both the grips 13, respectively.

The control unit 200 can control the overall operation of the safeguard apparatus 1000 for bicycle. In particular, the control unit 200 receives the output signal of the sensor unit 100 to obtain driving information including the driving speed, the road surface condition, the current position and the posture of the occupant, and compare the driving information and the safe driving reference. In addition, the control unit 200 can record the acquired driving information in the memory unit 300. [ For this purpose, the control unit 200 may include a travel information obtaining unit 210 and a travel information comparing unit 220.

The travel information obtaining unit 210 can check whether the pedal 17 is rotating and whether the rider 13 or the saddle 12 is in contact with the occupant 11 to check whether the bicycle 10 is running. The travel information obtaining unit 210 can check whether the pedal 17 is rotated according to the output value of the magnet contact sensor 120. [ The travel information obtaining unit 210 can check whether or not the handle 13 and the saddle 12 of the passenger 11 are in contact with each other according to the output value of the switch sensor 170. [ The travel information obtaining unit 210 can determine that the bicycle 10 is traveling when the pedal 17 is rotating and the touch of the handle 13 or the saddle 12 of the occupant 11 is confirmed.

The driving information obtaining unit 210 can calculate the traveling speed of the bicycle 10 while driving. The driving information obtaining unit 210 may calculate the number of rotations of the wheel 11 according to the output value of the optical sensor 130. [ For example, when the circular plate 500 is implemented to have three reflection areas 500b and absorption areas 500a as shown in FIG. 4, when the wheel 11 rotates once, the photosensor 130 detects light Absorption can be repeated three times. Therefore, the travel information obtaining unit 210 can increase the count value at the boundary where the light sensor 130 absorbs light, and can be regarded as the wheel 11 rotating once when the count value becomes 3 times. The driving information obtaining unit 210 can calculate the number of revolutions of the wheel 11 in this manner. The travel information obtaining unit 210 may calculate the travel distance using the rotation number of the wheel 11 and the radius value of the wheel 11 stored in advance. The travel information acquiring unit 210 can confirm the travel time from the clock sensor 140.

To this end, the driving information obtaining unit 210 may receive the traveling speed information and may receive the angular velocity value measured by the direction sensor 110. [ The driving information obtaining unit 210 can confirm whether the road surface is up, down, or flat by reflecting both the running speed and the variation width of the angular speed value. For example, the travel information obtaining unit 210 monitors changes in the y and z axes of angular velocity values measured by the direction sensor 110, and when the change width is larger than the preset up or down change width, It can be confirmed that the road surface is uphill or downhill. Otherwise, the driving information obtaining unit 210 can confirm that the vehicle is on the flat surface. In addition, the travel information obtaining unit 210 can confirm the road surface state of the uphill or downhill event when the current running speed is less than or equal to the predetermined uphill speed, or is lower than the downhill speed.

The driving information obtaining unit 210 can obtain the current position of the bicycle 10. [ The travel information obtaining unit 210 obtains the primary position using the Wi-Fi beacon 150, acquires the secondary position using the GPS sensor 160, compares the primary position and the secondary position, Location can be obtained.

For example, the running information obtaining unit 210 can check the SSID value and the RSSI value of the AP installed in the vicinity recorded in the Wi-Fi beacon 150. The driving information obtaining unit 210 can identify the three APs closest to the bicycle 10 according to the RSSI value recorded in the Wi-Fi beacon 150, substitute the SSID value of the corresponding AP into the match function, The hardness value can be obtained. The driving information obtaining unit 210 may calculate the first position value of the bicycle 10 in such a manner that the obtained latitude and longitude values are converted into x, y, and z values and applied to the triangulation algorithm. The driving information obtaining unit 210 may calculate the latitude and longitude values obtained by the GPS sensor 160 as the second position value of the bicycle 10. [ The driving information obtaining unit 210 compares the first position value and the second position value, and when the error is less than or equal to a predetermined threshold value, either the first position value or the second position value can be acquired as the current position of the bicycle have. This is to increase the accuracy of the current position of the bicycle 10.

The driving information obtaining unit 210 can obtain the driving posture of the occupant 11. The travel information acquiring unit 210 can confirm whether the passenger 11 is in a sitting position on the saddle 12 by holding both the grips 13. [ The driving information obtaining unit 210 can confirm whether or not the occupant 11 has fallen. The travel information obtaining unit 210 can check whether the passenger 11 grasps both the grips 13 according to the output value of the switch sensor 170 and confirm whether or not the sled 11 is seated in the saddle 12.

Specifically, the travel information acquiring unit 210 monitors changes in the x and z axes of angular velocity values measured by the direction sensor 110, and when the change width is greater than a preset change width, for example, If the gyro value measured in real time by the direction sensor 110 after time passes has converged to 0, it can be confirmed that the passenger 11 has fallen. In this case, the travel information obtaining unit 210 may store the travel information at the time of the fall, i.e., the traveling speed, the road surface state, the current position, the current time, etc. separately in the memory unit 300.

The traveling information comparison unit 220 compares the traveling speed, the road surface condition, the current position, and the traveling information of the occupant's traveling posture with the safety traveling reference preset for each traveling information, So that the map notification sound is output through the output unit 400. [

When the traveling state comparison unit 220 determines that the road surface state is flat, the traveling speed and the occupant's traveling posture can be compared with the safe traveling reference, respectively.

The traveling information comparator 220 compares the traveling speed with a predetermined safe traveling speed and controls the traveling information comparator 220 to output a driving map notification sound (for example, "reduce the speed") when the traveling speed is equal to or greater than the safe traveling speed can do. At this time, the safe running speed may be set by the guardian of the passenger, or may be set according to the traveling pattern analysis result in the management server 20 described later.

The travel information comparison unit 220 can compare a plurality of travel postures to which a risk value is assigned stepwise with the travel posture. The travel information comparing unit 220 can check which of the plurality of travel positions the travel position corresponds to thereby obtain the risk value of the travel position. The travel information comparing unit 220 can control the output of the driving map alarm sound (for example, "catch both handles") corresponding to the traveling posture if the risk value of the traveling posture is equal to or greater than a predetermined risk value have.

When the traveling state comparison unit 220 determines that the road surface state is an uphill or downhill state, it can control so that a driving guidance sound (for example, "pull off the bicycle and go away"

The travel information comparison unit 220 can compare the current location with the safe travel reference. The travel information comparing unit 220 may compare the current position with a predetermined dangerous position. Here, the dangerous position may be set in advance by a guardian of the passenger 11 to a position not suitable for driving the bicycle 10, such as a construction site. The traveling information comparator 220 can control the output of the driving map notification sound (for example, "out of the current position") if the present position corresponds to the preset dangerous position.

In addition, the travel information comparing unit 220 can compare the distance from the starting point with the predetermined safety distance. The travel information comparing unit 220 can control the output of a driving map alarm sound (e.g., "return to the starting point") when the distance to the current position is equal to or greater than the preset safety distance from the starting point.

The memory unit 300 may store a program for processing and controlling the safeguard apparatus 1000, and may perform a function for temporarily storing input / output data. In particular, the memory unit 300 may record driving information acquired by the control unit 200, and the driving information may be transmitted to the management server 20 via the Wi-Fi beacon 150. Alternatively, the memory unit 300 may be implemented as an SD card, read the SD card from the user terminal 30, and transmit the travel information to the management server 20.

The output unit 400 may output a driving guidance sound according to the control of the controller 200, and may be implemented as a speaker. At this time, the driving guidance sound may be a voice recorded directly by the guardian of the occupant 11. To this end, the bicycle safety device 1000 may further include a separate microphone module.

The bicycle safety device (1000) can extract the traveling pattern by analyzing the traveling information by the driving date. For example, the safety device for a bicycle 1000 can extract a traveling pattern such as overspeed at a specific position, speed control according to traveling time, number of times of falling during one traveling, number of times of falling for each traveling speed, and the like.

The traveling pattern extracting unit 23 can provide the traveling pattern to the user terminal 30. [ For example, the driving pattern extracting unit 23 can provide a driving pattern to the user terminal 30 in a manner of constructing and uploading a web site. The user terminal 30 outputs such a driving pattern, and training for correct driving habit settlement can be performed based on the driving pattern.

The safe running reference updating unit 24 can update the safe running reference by comparing the running pattern by date. The safe driving reference renewal unit 24 can compare the driving pattern extracted at the time of the previous driving with the driving pattern extracted at the time of the current driving to check whether the driving habit improves according to a predetermined rule. For example, the safe running criterion updating unit 24 compares the number of times the vehicle falls down, and can confirm whether the driving habits are improved by reflecting the number of times the vehicle falls.

The safe running reference renewal unit 24 can update the safe running criterion according to a predetermined rule when it is confirmed that the driving habit is improved. The safety driving criterion is a criterion for determining whether or not the safe driving guidance sound is output from the safety device for cycling (1000). If the driving habit improves, the user can add fun to the bicycle by adjusting the standard. For example, the safe running criterion updating section 24 can increase the safe running speed if it is confirmed that the driving habit is improved.

The safe driving reference updating unit 24 can directly transmit the information to the safety device for cycling 1000 so that the updated safety driving standard can be reflected. Alternatively, the safe running criterion updating section 24 can update the safe running criterion stored in the safeguard apparatus 1000 for bicycles via the user terminal 30.

The management server memory unit 25 may store a program for processing and controlling the management server 20 and may perform a function for temporary storage of data to be input / output.

Hereinafter, the control method of the management server 20 shown in Fig. 8 will be described with reference to Fig.

9 is a flowchart of a control method of the management server shown in FIG.

Referring to FIG. 9, the management server 20 can receive the driving information acquired by the safety device 1000 for a bicycle (900).

The management server 20 collects driving information for each driving date (910) and extracts the driving pattern (920).

The management server 20 compares the travel pattern of the previous date with the travel pattern of the current date (930), and confirms whether the safe travel reference update is possible (940). The management server 20 can confirm whether the safe running reference update is possible by checking whether the driving pattern is improved according to a predetermined criterion.

The management server 20 may update the safe driving criteria (950) if it is confirmed that the safe driving criteria update is possible (940).
