Abstract

The invention discloses a driver vitality sign detection device and method. The device is composed of a signal collection unit, a front-end signal filtering amplification unit, a central processing unit DSP arithmetic unit and a rear-end alarm unit, wherein the signal collection unit is installed at the frequent-touch position of a steering wheel and is a touch miniature photoelectric measuring instrument. Sign feedback signals of a driver are collected for rear signal processing and operation to obtain the accurate heart rate and blood oxygen concentration of the driver. The physical state of the driver is judged according to a preset threshold value or limit, and an alarm signal is given correspondingly. According to the driver vitality sign detection device and method, a packaged touch sensor is customized according to the principle that the infrared absorption and red light absorption of human body blood oxygen content are different, detection of the human body vitality sign of the driver is simplified, discomfort of a traditional testing method is eliminated, the physical state of the driver can be continuously reflected in time, the accurate and effective alarm remind can be provided, and life safety of persons inside an automobile is ensured.

Description

technical field [0001] The present invention relates to a driving safety device and its usage method, in particular to a driver's vitality characteristic detection device and its detection method for automobiles, which can detect the driver's heart rate and blood oxygen concentration in real time and continuously through compact software and hardware to ensure Technology solutions for safe driving. Background technique [0002] At present, in the automotive industry, the detection of the vitality characteristics of the driver in the car is basically blank, because it is basically impossible to move the complete set of equipment from the hospital into the car, and the simplified test has always been a technical problem that needs to be broken through. [0003] The current common testing methods are generally direct blood sampling or finger clip type, but it is basically impossible or unusable convenience in the car. Especially the clip-on type, there are problems such as pre...
