Physiologic signal monitoring system and method of driver

Abstract

The invention discloses a physiologic signal monitoring system and a method of a driver. The system comprises a sensor module, an amplifying circuit, a filter circuit, a self-learning module, a CPU (Central Processing Unit) and an automobile control system, wherein the sensor module comprises a plurality of sensors for detecting a plurality of physiologic signals of the driver; the amplifying circuit is connected with the sensors of the sensor module and used for amplifying the physiologic signals detected by the sensors; the filter circuit is used for filtering the amplified physiologic signals to remove interfering signals; the self-learning module carries out self-learning to statistically obtain normal values of the physiologic signals of the driver and takes the normal values as reference values for judging whether the driver is in a fatigue driving state; the CPU acquires the physiologic signals of the driver and compare the physiologic signals with the reference values to judge whether the driver is in a drunk driving wait or fatigue driving state, and transmits a control signal to the automobile control system according to a compared result; and the automobile control system is controlled by the control signal transmitted by the CPU. The system and the method realize real-time monitoring of the physiologic signals of the driver.

Description

technical field [0001] The invention relates to the technical field of detecting physiological signals of drivers in public transportation, in particular to a monitoring system and method for physiological signals of drivers. Background technique [0002] In recent years, with the increase in the number of cars and the expansion of road construction scale, traffic accidents and other issues have become increasingly prominent, among which drunk driving and fatigue driving are the main causes of traffic accidents. [0003] For drunk driving, although the traffic police department has strengthened supervision on drunk driving, the alcohol content tester is a passive inspection device. examine. Only by eliminating drunk driving can we reduce drunk driving accidents, so we need a device to prohibit the activation of the car control system (SBC) when the alcohol concentration exceeds the set value. [0004] Fatigue driving refers to the fact that the driver is tired during drivi...
