  The LED display unit 200 is provided on the outer side of the backpack body unit 100, for example, on the opposite side of the back-packing part of the backpack body unit 100, and can transmit a specific display to a person coming from behind, Since wireless communication with the external device 10 such as a smartphone is possible, symbols and messages including various figures, characters, and the like can be displayed according to a signal input from the external device 10.

  Examples of the symbols and messages that can be displayed on the LED display unit 200 include display of the progress direction such as forward, left turn, and right turn, and display of the progress status such as stop and emergency. Display is also possible.

  Other indications of progress or progress include slowing down, slowing down, accelerating, road attention (danger / caution), changing teams (proceeding in one row, proceeding in two rows, etc.), proceeding closely, allowing overtaking, Indications such as overtaking (overtaking the previous person, overtaking from the left, overtaking from the right, etc.), scattered freely to the next destination, etc. may be displayed in the form of predetermined symbols or text messages .

  In addition, as messages that can be transmitted in the form of characters, help expressions such as help, thank, sorry, etc. can be transmitted to people who follow from behind.

  The communication of such intention expression displayed on the LED display unit 200 may be performed by using a linked application installed in the external device 10 such as a smartphone that can communicate with the drive control unit 600 that controls the LED display unit 200. it can. In addition, the connection between the LED display unit 200 and the external device 10, that is, the connection between the LED display unit 200 and the external device 10 via the drive control unit 600, has a small power consumption instead of a short communication distance. A communication method such as Bluetooth can be used, but is not limited to this, and any wireless communication method can be used as long as power consumption is low and communication is not hindered.

  Meanwhile, the LED display unit 200 transmits the state of the LED display unit 200 to the external device 10 via the drive control unit 600 and displays what shape is displayed on the high-brightness LED mounted on the backpack. Or displayed on an external device.

  The backpack body unit 100 can store a power supply unit 300 that is detachably formed. The power supply unit 300 can be used to supply power to the LED display unit 200.

  Hereinafter, an embodiment of an illumination control unit for controlling the LED display unit of the multifunction smart backpack according to the present invention will be described in detail with reference to FIGS.

  FIG. 3 is an exemplary view showing a palm of the illumination control unit formed in a form of wearing a glove, and FIG. 4 is an exemplary view showing a back of the hand of the illumination control unit formed in a form of wearing a glove, FIG. 5 is a detailed block diagram of the illumination control unit, FIG. 6 is an exemplary diagram illustrating that the pressure recognition unit of FIG. 5 operates, and FIG. 7 illustrates that the motion recognition unit of FIG. 5 operates. FIG.

  In one embodiment of the multi-function smart backpack according to the present invention described above, whether the figure or characters displayed on the LED display unit 200 of the multi-function smart backpack is selected by operating the external device 10 such as a smartphone. Or whether it is displayed or not.

  When both hands are relatively free, for example, when climbing, it seems that there is no particular difficulty or danger in controlling the LED display unit 200 by operating the external device 10 in this way. It is not recommended to operate the external device 10 such as a smartphone in a situation where both hands are not free as in the case of traveling, because there is a risk of an accident. Accordingly, there is a need for means capable of controlling the LED display unit 200 of the multifunction smart backpack according to the present invention in such a state where the use of both hands is not free.

  For example, a glove-shaped illumination control unit shown in FIGS. 3 and 4 is a smart example of the illumination control unit 400 that can wirelessly transmit a signal instructing to display a graphic or a character on the LED display unit 200. It may be used as a stand-alone control unit that replaces a device, or as a subordinate control unit that is used while being wirelessly connected to a smart device.

  As shown in FIGS. 3 and 4, the illumination control unit 400 is formed by wearing gloves on both hands, and as shown in FIG. 5, the pressure recognition unit 420, the switch unit 430, and the motion recognition unit 440. , A motion recognition unit 450 and a command processing unit 460 may be included.

  As shown in FIG. 6, the pressure recognition unit 420 includes a pressure sensor 421 at a portion corresponding to the second joint of the index finger or little finger, and displays a stop display when a certain pressure is detected by the pressure sensor 421. A control signal is transmitted to the wireless communication module 490.

  In other words, when the pressure sensor 421 is attached to a portion that comes into contact with the brake when the brake is applied, and the pressure sensor 421 detects a pressure exceeding a predetermined reference, it can be determined that the brake is applied. If it is determined that the brake is applied, a stop display control signal is transmitted to the wireless communication module 490 so that a display corresponding to the stop can be displayed on the LED display unit 200.

  At this time, in order to prevent malfunction, a stop display control signal is generated and transmitted to the wireless communication module 490 only when there are two or more pressure sensors 421 in which a pressure exceeding a predetermined reference is detected. As described above, a pressure processing unit 422 may be further included. The pressure processing unit 422 is set to transmit the stop display control signal only when there are three or more pressure sensors 421 in which a pressure equal to or higher than a predetermined reference is detected, as necessary or selected. May be. The pressure processing unit 422 is preferably provided between the pressure sensor 421 and the wireless communication module 490.

  As described above, when the stop display (brake display) is configured to be displayed by the detection of the pressure sensor, a sudden burst situation in which it is difficult to operate the illumination control unit 400 with a finger occurs. However, since the stop display appears on the LED display unit 200 at the same time as the brake is naturally applied, it is further effective in improving safety.

  As shown in FIGS. 3 and 4, when the switch unit 430 is positioned at a corresponding portion between the thumb and the index finger and the switch unit 430 corresponding to the left hand is pressed, the left turn display control signal is applied to the right hand. When the switch unit 430 is pressed, a right turn display control signal is transmitted to the wireless communication module 490.

  Unlike the stop display, the left-turn display or the right-turn display that informs the driving intention is preferably performed manually rather than automatically because it is necessary to notify in advance in which direction the vehicle turns during driving. However, since it is dangerous to release the hand from the handle at this time, it is preferable to be able to display left or right turn while holding the handle, and for that purpose, switch to the corresponding part between the thumb and index finger. The switch unit 430 can be pushed by bringing the thumb close to the forefinger side to inform the user in advance in which direction he / she will change direction.

  As shown in FIGS. 3 and 4, the motion recognition unit 440 includes an IMU (Internal Measurement Unit) in which a 3-axis acceleration sensor, a 3-axis gyro sensor, and a 3-axis geomagnetic sensor are included in a part corresponding to a hand or a finger. , An inertial measurement device) provided with a sensor module.

  The acceleration sensor detects the acceleration generated from the movement of the user's finger, the gyro sensor detects the angular velocity rotated around a certain axis generated by the movement of the user's finger, and the geomagnetic sensor measures the earth's magnetic field. To do.

  The acceleration data is integrated to obtain the velocity, and this value is integrated again to obtain information on the distance the sensor has moved, and the angular velocity data can be integrated to obtain rotation angle information about the three axes of the sensor. .

  An IMU (Internal Measurement Unit) sensor module can measure the direction in which the sensor heads using values of acceleration, gyroscope, and geomagnetic sensor. That is, direction information can be output, which consists of yaw, roll, and pitch (yaw, roll, pitch). The yaw is the angle at which the sensor is rotated from the direction indicated by the compass with respect to the axis parallel to the direction of gravity, and the pitch is the angle at which the sensor is rotated relative to the plane parallel to the ground with respect to the y-axis of the sensor. The roll means an angle rotated with respect to a plane parallel to the ground with respect to the x-axis of the sensor.

  As shown in FIG. 7, when the motion recognition unit 450 senses a motion in space from the motion recognition unit 440, the motion recognition unit 450 performs an effective motion based on preset sensitivity information or preset motion information. Judging. Here, the sensitivity information refers to information that has moved a certain distance or more at a certain speed, and the preset motion information refers to information that corresponds to the shape of the hand.

  That is, the movement generated during general riding is ignored, and when a specific movement is detected, it is determined as an effective movement. This is because there is an unavoidable movement during riding, but when determining whether or not it is a command for all such movements, there is a problem that the amount of data processing increases rapidly. is there.

  As shown in FIG. 7, when the motion recognition unit 440 determines that there is a command corresponding to the effective motion, the command processing unit 460 checks whether there is a command corresponding to the valid motion. The control signal is transmitted to the LED display unit 200.

  This is for transmitting an intention to express to another person based on the movement of the hand or finger, and can be exemplified by a hand signal exchanged during riding. Most riders have a promised hand signal that is used to communicate. However, it is difficult to utilize such hand signals at night, and in order to solve this, using the multi-function smart backpack according to one embodiment of the present invention including the lighting control unit as described above, You can also use hand signals at night.

  When the illumination control unit 400 in the form of a glove as described above is used, the LED display unit 200 is configured to decode the signal of the illumination control unit 400 by itself and display graphics and characters corresponding to the signal. obtain. Such an illumination control unit 400 corresponds to a stand-alone control unit, and can display graphics or characters displayed on the LED display unit 200 even when there is no external device 10 such as a smartphone. Selection and display can be controlled within a limited range.

  Unlike this, the illumination control unit 400 may be configured to be paired and interlocked with the external device 10 such as a smartphone instead of the LED display unit 200 and transmit the control signal only to the external device 10. In this case, the control signal of the illumination control unit 400 is decoded by the external device 10, and the external device 10 transmits the decoded signal such as a figure or a character to the LED display unit 200 so that the LED display unit 200 displays the signal. can do. In this case, the illumination control unit 400 does not control the LED display unit 200 alone, but is used as a subordinate control unit subordinated to the external device 10 in cooperation with the external device 10 such as a smartphone. .

  Hereinafter, another embodiment of the multifunction smart backpack according to the present invention will be described with reference to FIGS.
