detailed description

In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following embodiments specifically illustrate the principles, steps of use, and technical effects of the device for reminding and preventing fatigue driving of the present invention in conjunction with the accompanying drawings.

Example

Fig. 1 is a structural block diagram of the device for reminding and preventing fatigue driving of the present invention.

As shown in Figure 1, the device of reminding and stopping fatigue driving in the present embodiment is communicated with the traffic management center of the outside, has judgment controller 1 and the infrared scanner 2 that is connected with this judgment controller 1 two-way communication and data processing Device 3, signal generating transmitter 4, alarm device 5 and locator 6.

The infrared scanner 2 is arranged at the position facing the driver's eyes in the cab of the car, scans and acquires the driver's eye information in real time, and sends the eye information to the data processor 2 in real time.

The data processor 3 is communicated with the infrared scanner 2, analyzes and calculates the driver's eye frequent closing time t from the eye information.

The judging controller 1 judges whether the frequent eye closure time is greater than a predetermined fatigue judging threshold, and sends out a control instruction when the judging result is yes. The fatigue judgment threshold is determined according to different seasons and times. When the season is easy to sleepy summer or after nine o'clock in the evening, the fatigue judgment threshold is set at a lower level, which is 3-5 minutes. In this embodiment, it is set to 3.5 minutes. The rest of the time is increased accordingly, for 8-20 minutes.

Alarm 4, in the present embodiment, is a sound and light alarm, which sends an alarm after receiving a control command.

The locator 5, in this embodiment, the locator is a GPS locator, and after receiving the control command, record the position information at this time, which is the GPS position coordinates.

The signal generation transmitter 6 is connected to the locator 5 in communication, and after receiving the control instruction and obtaining the location information, it sends the judgment result and the location information to the traffic management center. After receiving the information, the traffic management center will focus on the driver's driving situation, check whether the car is equipped with a rotating driver, and send nearby traffic police to check at the first moment. After the alarm is eliminated, the traffic management center eliminates its monitoring.

After the fatigue driver receives the alarm, if there is a driver in rotation, after parking, the locator detects that the position does not change, and the judging controller sends an instruction to make the alarm stop alarming. At the same time, the alternate driver got off the passenger seat and entered the driver's seat, and then drove again. Now the infrared scanner 2 continues to scan in real time to obtain the eye information of the new driver. Since the new driver is not fatigued, after being scanned by the infrared scanner 2, the frequent eye closure time that is less than the fatigue judgment threshold will be sent correspondingly, thereby Make the alarm stop and drive normally.
