Fatigue driving warning device and fatigue driving warning method

The invention relates to driving safety; in particular to a fatigue driving warning device and a fatigue driving warning method.

Driving is less likely to be self-conscious, and often has a wrong estimate of physical strength and barely on the road, or because of long-distance driving for a long time, the spirit is not good enough, and the attention can not be concentrated, resulting in traffic accidents. Because fatigue driving can't be avoided by the personal will of driving, it is more difficult to prevent road safety factors than drunk driving; therefore, how to judge the fatigue of driving in driving, it becomes safe for maintenance. A big topic.

There are a number of conceptual methods for judging driving fatigue, such as the blinking frequency of driving or facial expression changes (such as yawning) to determine their fatigue, etc., but the accuracy of these explicit "body language" It is not as good as the physiological characteristics of the body, and the fact that the blood oxygen concentration can be used as the basis for fatigue is known to the medical community. However, the existing oximeters are mostly finger-clip design, and the oximeter needs to be clamped to the fingers. The head is used to detect the blood oxygen concentration. This kind of detection will make the driver tie the foot and is not suitable for the vehicle.

In view of the above, the object of the present invention is to provide a fatigue driving warning device and a fatigue driving warning method capable of determining the fatigue degree by detecting the blood oxygen concentration of the driving without affecting the general operation of the driving to the vehicle. Can further boost the spirit of driving.

In order to achieve the above object, the fatigue driving warning device provided by the present invention comprises an oximeter, a message receiving unit and an audio playing unit; the oximeter is worn on a driving body and has a sensing unit. The sensing unit is configured to measure a blood oxygen concentration of the driving earlobe portion, and send a warning message when the blood oxygen concentration of the driving is lower than a threshold value; the message receiving unit is configured to receive the blood oxygen machine The warning message sent by the sensing unit sends a start message after receiving the warning message; the audio playback unit is configured to receive the start message sent by the message receiving unit, and play after receiving the start message An audio message.

The fatigue driving warning method provided by the present invention comprises the steps of: measuring a blood oxygen concentration of a driving earlobe portion; and sending a warning message if the measured blood oxygen concentration is lower than a threshold value; receiving the warning message and converting into A start message is used to control the broadcast of an audio message.

Thereby, the fatigue driving warning device and the fatigue driving warning method provided by the present invention can measure the fatigue degree without affecting the operation of the vehicle, and can further enhance the spirit.

1 is a schematic view of a preferred embodiment of the fatigue driving warning device of the present invention; FIG. 2 is a perspective view of the oximeter of the preferred embodiment of the present invention; FIG. 3 is a flow chart of the fatigue driving warning method of the present invention; 4 is a schematic view of another preferred embodiment of the fatigue driving warning device of the present invention.

In order to explain the present invention more clearly, the preferred embodiment will be described in detail with reference to the drawings. Referring to FIG. 1 to FIG. 3, the fatigue driving warning device 100 of the first preferred embodiment of the present invention includes a The oximeter 10, a message delivery unit 20 and an audio playback unit 30. The oximeter 10 has a clamping member 12, a photosensitive member 14 and a illuminating member 16; the clamping member 12 is sandwiched on a driving earlobe, and the clamping member 12 has two opposite clamping faces 12a. And the photosensitive member 14 and the illuminating member 16 are combined into a sensing unit, and the photosensitive member 14 and the illuminating member 16 are disposed on the clamping surface 12a and abut against the earlobe surface of the driving. It should be noted that, in this embodiment, the photosensitive member 14 and the illuminating member 16 are simultaneously disposed on the clamping surface 12a, so the sensing unit adopts a reflective blood oxygen concentration measurement method; in other embodiments, The photosensitive member 14 and the illuminating member 16 can also be respectively disposed on the clamping surface 12a and the other clamping surface 12b. If designed according to the design, the sensing unit adopts a penetrating blood oxygen concentration. Test method.

The fatigue driving warning method provided by the present invention can be used in conjunction with the fatigue driving warning device 100; the oximeter 10 is disposed on the earlobe of the driving through the clamping member 12, and the photosensitive member 14 and the illuminating member are 16 measures the blood oxygen concentration of the driving earlobe portion; if the blood oxygen concentration measured by the blood oxygen meter 10 is lower than a threshold value, it means that the fatigue of the driving may have reached the degree of fatigue driving, the blood oxygen machine 10 A warning message W is sent to the message delivery unit 20 via Bluetooth technology.

In the embodiment, the message receiving unit 20 is a vehicle device installed on the vehicle, but is not limited thereto. The message receiving unit 20 is responsible for receiving the warning message from the oximeter 10 . W, and after receiving the warning message W, sends a start message P, and transmits the start message P to the audio play unit 30 through the Bluetooth technology. The audio playback unit 30 is located on the oximeter 10, and the audio playback unit 30 has an optical player 10 and an earphone 34. The oximeter 10 is mounted on the driver. When the ear is suspended, the earphone 34 can be placed in the ear of the driving; after receiving the activation message P, the audio playback unit 30 can play an audio through the earphone 34; the audio can be It is a wake-up reminder sound, or a music that can inspire the driving spirit. It is to be noted that in the embodiment, the oximeter 10, the message delivery unit 20 and the audio playback unit 30 use Bluetooth technology to transmit the alert message W and the activation message P. In other embodiments, Different connection methods are also available.

FIG. 4 is a schematic diagram of a fatigue driving warning device 200 according to a second preferred embodiment of the present invention. The structure is substantially the same as that of the first preferred embodiment, and the details are not described herein except that the audio playback unit 40 is different. It is not located above the oximeter 10, but exists independently. In practice, the audio playback unit 40 can be used in conjunction with the sound system of the vehicle.

Thereby, the fatigue driving warning device and the fatigue warning method provided by the invention can measure the fatigue degree without affecting the driving operation of the vehicle, and timely boost the driving spirit when the driving may be in a dangerous driving situation. To avoid dangers.
