4 is a view showing the configuration of the drunk driving prevention device of FIG.

Hereinafter, for convenience of explanation, the drunk driving prevention apparatus 100 of this embodiment will be described with reference to FIGS. 1 to 3 described above along with FIG. 4 .

Referring to the drawings, the device for preventing drunk driving 100 may include a sensor unit 102 and a body 101 connected to the sensor unit 102 through an electric wire 103 .

The sensor unit 102 of the apparatus 100 for preventing drunk driving may detect a user's biosignal, for example, at least one of a heart rate and oxygen saturation. To this end, the sensor unit 102 may be disposed on the handlebar 22 of the handle portion 20 of the bicycle 10 to which the driver's hand is in contact. The sensor unit 102 may include a heart rate sensor 110 and an oxygen saturation sensor 120 .

The heart rate sensor 110 may be in contact with the driver's finger to sense the driver's heart rate. The heart rate sensor 110 may provide a first detection signal, eg, a heart rate signal, according to the detection result to the main body 101 through the wire 103 .

The heart rate sensor 110 may be a photoplethysmography (PPG) sensor that generates a first detection signal related to a heart rate according to the intensity of light reflected from the driver's finger artery, but is not limited thereto.

The oxygen saturation sensor 120 may be in contact with the driver's finger to sense the oxygen saturation amount in the driver's blood. The oxygen saturation sensor 120 may provide a second detection signal according to the detection result, for example, an oxygen saturation amount signal to the body 101 through the wire 103 .

The oxygen saturation sensor 120 may be a finger pulse oximeter that generates a second detection signal related to an oxygen saturation amount according to a ratio of light absorbed by the driver's finger, but is not limited thereto.

Meanwhile, according to another embodiment of the present invention, the sensor unit 102 may be in the form of a wearable device worn on the driver's body. For example, the sensor unit 102 may be implemented in a watch worn on the driver's wrist or a ring worn on the driver's finger. In this case, the sensor unit 102 is further provided with a communication unit (not shown) for performing wireless communication to transmit a detection signal to the main body 101 .

The main body 101 of the drunk driving prevention device 100 is connected to the sensor unit 102 through the electric wire 103, and by analyzing the detection signal provided from the sensor unit 102, it is possible to determine whether the driver is drinking. . In addition, the main body 101 may control the operation of the brake system 50 of the bicycle 10 according to the result of determining whether or not to drink.

For example, as shown in FIG. 2 , the main body 101 may be connected to the brake wire 60 and the brake system 50 through the second sub-wire 105 . And, if it is determined whether the driver is drinking, the main body 101 may pull the second sub-wire 105 with a predetermined traction force to pull the brake wire 60 connected thereto. Accordingly, in the brake system 50 , the brake pads 53 are in close contact with the tire rims of the wheels 40a and 40b , and thereby the bicycle 10 is braked and does not move.

To this end, the main body 101 may include an analysis unit 130 and a braking unit 140 .

The analysis unit 130 may analyze the detection signal provided by the sensor unit 102 , that is, the first detection signal and the second detection signal to determine whether the driver is drinking.

In this case, the analysis unit 130 may first determine whether the driver is intoxicated according to the analysis of the first detection signal, and may secondarily determine whether the driver is intoxicated by analyzing the second detection signal according to the result.

Accordingly, the analysis unit 130 may determine whether the driver is intoxicated from the first determination result, or may determine whether the driver is intoxicated by synthesizing the first determination result and the second determination result.

The braking unit 140 may control the operation of the brake system 50 based on the determination result of the analysis unit 130 .

For example, when the analysis unit 130 determines that the driver is drinking, the braking unit 140 pulls the second sub-wire 105 according to the determination result, thereby operating the brake system 50 to brake the bicycle 10 . can do.

At this time, the braking unit 140 may pull the second sub-wire 105 with a traction force to the extent that the wheels 40a and 40b of the bicycle 10 are completely in a braking state, that is, not to move.

On the other hand, if the analysis unit 130 does not determine that the driver is drinking, the braking unit 140 does not pull the second sub-wire 105 according to the determination result. Accordingly, the brake system 50 may be operated according to the operation of the brake lever 21 of the handle portion 20 described above.

In this way, the drunk driving prevention device 100 of the present embodiment detects the biosignal of the driver who wants to drive the bicycle 10 to determine whether or not to drink alcohol, and the brake system 50 of the bicycle 10 according to the determination result. You can control the action. Therefore, the drunk driving prevention device 100 can prevent the driver from driving the bicycle 10 in a drunk state in advance, thereby preventing the safety of the driver and others from being threatened.

On the other hand, it has been described as an example that the above-described body 101 is disposed at a position not obstructing the driver's steering of the handlebar 22 , that is, disposed in the center of the handlebar 22 . However, the present invention is not limited thereto, and the main body 101 may be disposed in various positions that do not interfere with the steering of the bicycle 10 , for example, the frame 30 .

5 is a view showing a method for preventing drunk driving of a bicycle according to an embodiment of the present invention.

Referring to the drawings, the sensor unit 102 of the apparatus 100 for preventing drunk driving may detect one or more biosignals, ie, heart rate and oxygen saturation, from the driver's finger in contact with the handlebar 22 . Next, the sensor unit 102 may output a heart rate signal and an oxygen saturation signal according to the detection result, that is, a first detection signal and a second detection signal ( S10 ).

In this case, the bicycle 10 may be in a state in which the brake system 50 is being operated by the drunk driving prevention device 100 , that is, in a state locked by the brake system 50 .

In other words, in the initial state, the drunk driving prevention device 100 is pulling the second sub-wire 105 with a predetermined traction force, and accordingly, the brake system 50 is operated by the brake wire 60 and the bicycle ( 10) can be braked to maintain the immobile state.

Next, the analysis unit 130 of the main body 101 may analyze the first detection signal and the second detection signal provided from the sensor unit 102 to determine whether the driver is drinking.

First, the analysis unit 130 may compare the first detection signal with the first reference value Ref1, and may first determine whether the driver is drinking according to the comparison result (S20).

In this case, when the first detection signal, that is, the heart rate is equal to or greater than the first reference value Ref1 (Y), the analysis unit 130 may determine the driver's drinking state (S40). Here, the first reference value Ref1 may be one of approximately 150 to 160 values.

On the other hand, if the first detection signal is less than the first reference value Ref1 (N), the analysis unit 130 compares the second detection signal, that is, oxygen saturation with the second reference value Ref2, and from the comparison result, the driver's Whether or not drinking may be secondarily determined (S30).

As a result of the comparison, if the second detection signal is equal to or greater than the second reference value Ref2 (Y), the analysis unit 130 may determine the driver's drinking state (S40). Here, the second reference value Ref2 may be . (Please tell us the standard range of oxygen saturation level.)

On the other hand, when the second detection signal is less than the second reference value Ref2 (N), the analysis unit 130 may determine that the driver is in a non-drinking state (S45).

Subsequently, when the driver's drinking state is determined by the analysis unit 130 (S40), the braking unit 140 maintains the state in which the second sub-wire 105 is pulled, so that the bicycle by the brake system 50 The braking state of (10) can be maintained (S50).

On the other hand, when the driver's non-drinking state is determined by the analysis unit 130 (S45), the braking unit 140 releases the state in which the second sub-wire 105 is pulled, so that the bicycle ( The braking state of 10) may be released (S55).

Accordingly, the driver may brake the bicycle 10 by operating the brake system 50 through the brake lever 21 of the handle unit 20 while driving the bicycle 10 .

As described above, in the present embodiment, it is possible to determine whether the driver is drinking by sequentially analyzing two different bio-signals sensed from the driver. Therefore, the drunk driving prevention method of the present embodiment can accurately determine the drunk driving state of the driver and block the driver from driving the bicycle 10 in the drunk state in advance.
