Description

Anti-fatigue driving alarm

technical field

The utility model relates to a fatigue driving alarm device, in particular to an alarm device for preventing fatigue driving.

Background technique

The use of automobiles has become an important part of nation building and human life. However, traffic accidents in our country are also increasing day by day. In recent years, the annual death toll resulting therefrom is all about 80,000; especially the driver is driving on the expressway, and the accidents caused by fatigue driving are increasing unabated. How to reduce or avoid driver's fatigue driving has become a major problem in my country's transportation. Although the country has adopted a series of management measures in this regard, it has not been effectively solved so far with the improvement of economic benefits and people's pursuit of money.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides an alarm device for preventing fatigue driving, which solves the problem of alarming when the driver is fatigued and improves driving safety.

The utility model is realized by the following technical scheme: an alarm device for preventing fatigue driving, comprising a camera for collecting information on eye closure, an image analysis circuit connected with the camera, a processor connected with the image analysis circuit, and a processing An alarm connected to the alarm, a power circuit connected to the image analysis circuit, and a power supply connected to the alarm, the camera and the power circuit respectively.

The beneficial effects of the utility model are:

1. Solve the problem of alarm when the driver is fatigued and improve the safety of driving;

2. Small and compact, does not take up space, easy to install and maintain;

3. Simple and clear, easy to operate, timely reminder;

4. The manufacture is simple and does not require specific materials or production methods;

5. Low cost and easy to popularize.

Description of drawings

Below in conjunction with accompanying drawing and strength the utility model is further described.

Fig. 1 is a block diagram of the utility model.

Detailed ways

As shown in Figure 1, the anti-fatigue driving alarm device has a camera for collecting information on people's eye closure, an image analysis circuit connected to the camera, a processor connected to the image analysis circuit, an alarm device connected to the processor, and an image analysis circuit. The power circuit connected to the circuit is respectively connected to the power supply of the alarm, the camera and the power circuit.

In this embodiment, the power supply is a vehicle-mounted power supply. The camera is a small camera device, which is installed near the instrument panel at the lower end of the steering wheel of the car. The lens of the camera device is aimed at the driver's eyes, so that the internal chip technology locks the driver's eyes, and with the driver's As the eye moves, its lens moves with it. When the driver enters the cab and starts the car to enter the running state, the camera equipment also enters the working state at the same time. After the camera monitors the action information of human eyeballs and blinking, it compares it with the information stored in the system, and the camera device transmits the collected signals to the processor for analysis through the image analysis circuit. When the eyes are closed for more than a certain period of time, the processor sends a signal to the alarm to sound an alarm after analyzing and judging. The alarm is a buzzer or a voice alarm. When the alarm is a buzzer, it will remind the driver to pay attention to safe operation through sound; when the alarm is a voice alarm, it will remind the driver to pay attention to safe operation through voice. ``

During driving, if the driver's eyes are closed or the eyes do not turn for more than a certain period of time (the specific time can be set according to the driver's situation), for example, when the driver's eyes are closed for more than 2 seconds (when the speed of the car is 120km/h h, that is, 3.33m/s), or when the eyes do not move for more than 3 seconds, the alarm will sound immediately to remind the driver to pay attention to driving and prevent fatigue driving accidents.

Claims (3)

1. one kind prevents the fatigue driving alarm, it is characterized in that: comprise that one is used for gathering the camera of the closed information of eye, the graphical analysis circuit that is connected with camera, the processor that is connected with the graphical analysis circuit, the alarm that is connected with processor, the power circuit that is connected with the graphical analysis circuit, the power supply that is connected with alarm, camera and power circuit respectively.

2. the fatigue driving alarm that prevents according to claim 1 is characterized in that: described power acquisition vehicle power.

3. the fatigue driving alarm that prevents according to claim 1 and 2, it is characterized in that: described alarm is phonetic alarm or hummer.
