Abstract

The invention relates to a fatigue driving early warning wristband which integrates heart rate and driving action, and belongs to the technical field of smart wristbands and driving assistance systems. The heart rate sensor on the back of the bracelet, the heart rate sensor module embedded in the bracelet shell, the three-axis acceleration sensor module and the microprocessor chip. The method is to measure the heart rate of the human body and output real-time heart rate signals; detect the action acceleration of the driver's hand in the three dimensions of X, Y, and Z, and output real-time three-dimensional action acceleration information; Comprehensive judgment of fatigue driving situation. If it is judged that the current driving state is fatigued, the micro vibration motor will be driven to generate vibrations for fatigue warning. The bracelet of the present invention fuses and analyzes the detected two types of information, thereby realizing accurate judgment and early warning of fatigue driving.

Description

technical field [0001] The invention belongs to the technical field of smart wristbands and driving assistance systems, and in particular relates to a method and technology for judging and early warning of fatigue driving by utilizing the product form of the wristband. Background technique [0002] A smart bracelet is a wearable smart electronic device worn on the human wrist. Through various built-in sensors, such as three-axis acceleration sensor, three-axis gyroscope, GPS (Global Positioning System), heart rate sensor, temperature sensor, light sensor, noise sensor, bio-impedance sensor, etc., the location, distance, route, etc. Sports conditions, health conditions such as heart rate and skin temperature, as well as environmental conditions such as brightness and noise can be monitored, and functions such as sleep monitoring, emotional analysis, and fatigue reminders can be further realized. Through the built-in communication interface, such as Bluetooth, the smart brace...
