DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following detailed description, together with the accompanying drawings, is intended to illustrate exemplary embodiments of the invention and is not intended to represent the only embodiments in which the invention may be practiced.

Embodiments of the present invention propose a system that can secure the safety of a bicycle driver by controlling bicycle brakes and the like in a simple motion using a wearable device that can be worn by a bicycle driver.

1 is a configuration diagram of a control system such as a bicycle brake according to an embodiment of the present invention. Referring to FIG. 1, a control system 100, such as a bicycle brake, according to an embodiment of the present invention includes a wearable device 110 and a bicycle brake lamp 120.

The wearable device 110 is a device for controlling the bicycle brake lamp 120 as a device that a bicycle driver can wear on the body. Since the wearable device 110 is made of a flexible material, a wearer wearing a wearable device 110 can bend the wearable part. Specifically, the wearable device 110 senses the movement of the bicycle driver and recognizes the motion related to the bicycle travel state. The motion associated with the bicycle running condition may be set by matching various combinations of wearer's movements of the wearable device 110 with respect to various running conditions.

The bicycle brake 120 and the like can be mounted on the rear of the bicycle and the lighting state can be changed according to the motion recognition result of the wearable device 110. [ Specifically, the wearable device 110 displays a bicycle running state corresponding to the motion of the bicycle driver recognized by the wearable device 110. For example, the running condition may include at least one of slow, stop, left turn and right turn. However, the present invention is not limited to this, and may include various states that need to be displayed in order to secure the driving safety of the bicycle driver.

Hereinafter, each component of the wearable device 110 will be described.

The wearable device 110 may include a sensor unit 112, a control unit 114, and a communication unit 116. The sensor unit 112 may include one or more flex sensors for detecting bending of the wearable device 110 due to movement of the bicycle driver. The sensor unit 112 outputs the sensor data corresponding to the bending of the wearable part of the bicycle driver wearing the wearable device 110 to the control unit 114.

Flex sensors can be implemented in the form of strain gauges. The strain gauge detects the deformation of the surface of the object to be measured according to the change of the resistance value by using a metal or semiconductor whose resistance varies greatly depending on the magnitude of the applied force. Generally, a material such as a metal has a characteristic in which the resistance value increases as the length increases according to external force, and the resistance value decreases as the length decreases. When the resistance values of the respective flex sensors are changed, the magnitude of the electric signal output from each of the flex sensors is changed. The control unit 114 can determine the change of the output value of each flex sensor and determine the flexure. On the other hand, a flex sensor can be realized by a piezoelectric sensor or other bend sensor in addition to a strain gauge.

The control unit 114 may compare the sensor data received from the sensor unit 112 with at least one stored reference sensor data to determine whether the motion of the bicycle driver is related to the bicycle traveling state. The one or more reference sensor data is sensor data sensed when the wearer of the wearable device 110 performs motion related to one or more predetermined bicycle running conditions.

The control unit 114 determines whether the sensor data received from the sensor unit 112 and one or more stored reference sensor data are within an allowable error range. If the sensor data is within the tolerance range, It can be determined by the sensor data representing the related motion.

The communication unit 116 may transmit sensor data indicating the motion related to the bicycle traveling state among the sensor data received from the sensor unit 112 by the control unit 114 through a bicycle brake or the like.

The communication unit 116 may include a short-range communication module. The short-range communication module may include at least one of, for example, Wireless Fidelity (WiFi), Bluetooth, Near Field Communication (NFC), or Global Navigation Satellite System (GNSS).

Hereinafter, each component of the bicycle brake 120 will be described.

The bicycle brake 120 and the like may include a traveling state display unit 122, a control unit 124, and a communication unit 126. [ The display unit 122 may be implemented as an LED array including one or more LED light emitting elements, and may turn on / off one or more LED light emitting elements according to a control signal. Here, the control signal is a signal generated by the control unit 124 of the bicycle brake lamp 120 and is based on the sensor data of the wearable device 110. Examples of the lighting state shown in the traveling state display section 122 will be described later with reference to other drawings.

The control unit 124 generates a control signal for causing the traveling state display unit 122 to indicate the bicycle traveling state corresponding to the motion of the bicycle driver according to the sensor data representing the motion of the bicycle driver received from the wearable device 110 . That is, the control unit 124 generates a control signal for controlling the operation of the driving state display unit 122 so that the predetermined LED array corresponding to the sensor data representing the motion of the bicycle driver is lit.

The communication unit 126 can receive the sensor data representing the motion of the bicycle driver from the wearable device 11. [

The communication unit 126 may include a local communication module. The short-range communication module may include at least one of, for example, Wireless Fidelity (WiFi), Bluetooth, Near Field Communication (NFC), or Global Navigation Satellite System (GNSS).

Hereinafter, a specific example in which a bicycle driver wearing a wearable device 110 according to an embodiment of the present invention controls the bicycle brake lamp 120 through motion will be described with reference to FIGS. 2, 3A to 3D.

2 is an exemplary view of a wearable device according to an embodiment of the present invention.

FIGS. 3A, 3B, 3C, and 3D are views showing examples of a running status indicator of a bicycle brake or the like according to an embodiment of the present invention.

2, the wearable device 110 according to an embodiment of the present invention may be embodied as a glove-shaped device 200 in which one or more flex sensors 210, 220 for detecting bending are embedded in a finger portion have. The wearable device 110 is not limited to the glove shape shown in FIG. 2 but may be implemented in various forms including a helmet, clothes, and the like. One of the parts of the body where the bicyclist can most easily move without disturbing safety during his / her travel is a hand, so that it is preferably implemented in the form of a glove.

2, one flex sensor 210 and 220 are respectively mounted on the detection and stop portions of the glove-shaped device 200, but a flex sensor may be mounted on another finger portion, and a plurality of A flex sensor may be installed. In such a case, the motion associated with the bicycle running condition may include one or more actions to bend or straighten the bicycle driver's one or more fingers to indicate the running condition.

For convenience of explanation, in the following example, the bicycle driver wears the glove-shaped device 200 and controls the bicycle brake lamp 120 by the motion of only detecting and stopping, while the bicycle traveling state is the state of slowing down, As shown in FIG.

3A shows the running state display section 122a of the normal bike brake lamp 120 without changing the running state of the bicycle driver. When the driving status display unit 122a is implemented as an LED array, each LED light emitting device 122-1 is turned on and off according to a control signal of the control unit 124. [ The state shown in FIG. 3A can be obtained when the bicycle driver bends both the index finger and the stop finger. Bicycle drivers usually wrap their handles around the bicycle when driving.

FIG. 3B shows the running state display portion 122b when the bicycle driver makes a left turn. For example, when the bicycle driver performs a motion in which only the index finger is bent while both the index finger and the stopper are bent, an arrow shape indicating the leftward direction may appear in the driving status indicator 122b.

3C shows the running state display section 122c when the bicycle rider makes a right turn. For example, when the bicycle driver performs a motion in which only the stop and the stop are both in the bent state and only the stop is performed, an arrow shape indicating the right direction may appear in the running state display portion 122c.

Fig. 3D shows the running state display portion 122d when the bicycle rider is stopped while driving. For example, when the bicycle driver performs a motion of both detecting and stopping in a state in which both the detection and stop are bent, an X-shape may appear in the driving state indicator 122d.

In the case of the above-described example, by using a finger (in particular, sensing and stopping), which is the most movable body part during bicycling, the bicycle driver notifies pedestrians or other drivers of the driving state by only a simple motion, There is an effect that can be done. In particular, the motions exemplified in FIGS. 3A to 3D are operations that the driver intuitively can take in connection with the bicycle travel, which is effective in easily controlling the bicycle brakes and the like.
