Abstract

The invention relates to a fatigue driving monitoring system and monitoring method based on flexible electronic skin. The monitoring system comprises a wink signal collection unit, a signal conversion unit, a counting decoding driving unit, an LED display unit, a threshold comparison module, and an alarm prompting unit. The monitoring system uses a flexible electronic skin sensor attached to the periphery of orbicularis oculi muscle to detect wink movements of a user under different body conditions, counts obtained wink signals through the counting decoding driving unit, identifies the wink frequency p of the driver at the moment, and achieves real-time monitoring of fatigue driving. The monitoring system is simple in structure, convenient for use, light in weight, high in reliability, easy for carrying, low in cost, and easy for industrialization. As a novel intelligent fatigue-prevention detection system, the monitoring system is highly practical.

Description

technical field [0001] The present invention relates to the fields of sensor, signal processing technology, wireless sensor network, Internet of Things, etc., and in particular to a fatigue driving monitoring system and monitoring method based on flexible electronic skin, belonging to the field of intelligent control and Internet of Things. Background technique [0002] In recent years, with the continuous advancement of nanotechnology, flexible tactile sensors that can be used to detect multidimensional forces are becoming more and more important for the development of future smart instruments.
