Embodiment Construction
[0041] A smart watch-based early warning system for driver fatigue driving, which is characterized by comprising: a GPS module, a three-axis accelerometer, a CPU processor, and a vibration motor; the CPU processor communicates with the vibration motor through three I / O interfaces. The control terminal, the three-axis accelerometer, and the GPS module are electrically connected.
[0042] The three-axis accelerometer is installed in a smart watch on the wrist of a car driver to obtain real-time acceleration of the car driver's wrist swinging on the X-axis, Y-axis and Z-axis, and send it to the CPU processor.
[0043] The GPS module is installed in the smart watch on the wrist of the car driver, and is used to calculate the speed of the car in real time and send it to the CPU processor.
[0044] The CPU processor is used to receive the acceleration of the car driver’s wrist swinging on the X-axis, Y-axis and Z-axis in real time, and determine the motion characteristics of the car driver...

The invention discloses a smartwatch-based fatigue driving prewarning system for a driver. The basic thinking is that the wrist motion feature is monitored through a GPS module and a triaxial accelerometer which are built in a smartwatch to judge whether a car driver is in a dangerous driving state, if yes, a CPU built in the smartwatch monitors the wrist motion changes of the car driver through the triaxial accelerometer to further judge whether the car driver is in the fatigue driving state, if the car driver is in the fatigue driving state, the CPU triggers the control terminal of a vibrating motor to enable the vibrating motor to remind the car driver in a vibrating mode, and if the fatigue driving state is relieved, reminding is stopped. The smartwatch-based fatigue driving prewarning system for drivers can realize fatigue driving prewarning for the car driver.
Description
Technical field [0001] The invention belongs to the technical field of fatigue driving early warning, and in particular relates to an early warning system and an early warning method of a driver's fatigue driving based on a smart watch. Background technique [0002] Fatigue driving is one of the important causes of traffic accidents, and there are more and more studies on fatigue driving. At present, a variety of fatigue driving early warning systems have been developed at home and abroad, mainly using facial recognition technology, physiological detection equipment and sensing equipment to detect the driver’s fatigue state, but they all require additional auxiliary equipment, which is not only costly and mobile Poor sex and not conducive to marketization. [0003] The inventor found that with the continuous advancement of technology, three-axis accelerometers, GPS modules and vibration motors are installed on popular smart watches. The inventors use smart watches to develop drive...
