Problems solved by technology

[0002] In traffic accidents, the proportion of accidents caused by fatigue driving is relatively large. According to statistics, the traffic accidents caused by the above reasons account for more than 50%. Unresponsive, if the driver is not reminded in time at this time, traffic accidents are likely to occur
Although many people at home and abroad have done relevant research, the cost is relatively high
The United States has developed an infrared eye scanner. When the lens is aimed at the driver, the scanner will continuously emit infrared rays to scan the white part of the driver's eye, thereby judging the driver's fatigue. eye, is contrary to humanism
Domestic research is an image recognition device, but it is easily disturbed by the environment and errors occur
There is also a blood pressure identification device, but it is troublesome to wear, and sometimes physiological phenomena will cause identification errors

Embodiment Construction

[0016] Fig. 1 is a block diagram of a fatigue driving reminding device, which includes a car power supply, a transformer circuit, a sensor, a timing circuit, a control circuit and a voice circuit. Among them, the transformer circuit changes the voltage provided by the car power supply to 5V, and provides voltage for sensors, timing circuits, and control circuits. The control circuit is connected with the sensor, timing circuit and voice circuit.

[0017] Fig. 2 is a circuit schematic diagram of the voltage dividing part of the fatigue driving reminding device. The transformer circuit converts the car power supply to 5V voltage. Here, it is recommended to use 7805, U is the car power supply, S0 is the switch of the whole device, and Uo is the 5V voltage used by the internal circuit of the whole device.

[0018] Fig. 3 shows the sensor distribution of the fatigue driving reminding device. FIG. 3 shows the distribution of sensors 1 and 2 in a cross section of the steering wheel...

Abstract

The disclosed device is in use for preventing driver from driving car in fatigue state such as unfixed hands to cause driving accident. The device includes following parts: car electrical source for supplying power source for the device; potential device for transforming voltage of car electrical source to desired voltages; induction set for inducting contacting pressure between hands and steering wheel; timing device capable of sending signal to the caution unit according to prearranged adjustable time; control circuit for processing relation of sensor signal; sound device for providing caution voice after receiving control signal and caution voice having been recorded. The sound device includes sound circuit and sound-producing device. In the invention, sensor installed on steering wheel sends signal to the voice caution unit, which sends control signal to driver.

Description

technical field [0001] The invention relates to a safe driving device installed on a vehicle that conforms to human psychology, and in particular relates to a kind of inert state shown by the human body that causes hand relaxation when driving is fatigued, causing a sensor mounted on the steering wheel to send a signal to a voice reminder device, The voice reminder device sends a warning signal to the driver to ensure the reminder device for driving safety. Background technique [0002] In traffic accidents, the proportion of accidents caused by fatigue driving is relatively large. According to statistics, the traffic accidents caused by the above reasons account for more than 50%. Unresponsive, if the driver is not reminded in time at this time, traffic accidents are likely to occur. Although many people at home and abroad have done relevant research, the cost is relatively high. The United States has developed an infrared eye scanner. When the lens is aimed at the driver...
