Real-time monitoring system for state of automobile driver

Abstract

The utility model relates to a real-time state monitoring system, in particular to a real-time monitoring system for the state of an automobile driver, which comprises a pressure sensor, a respiration sensor, a three-direction acceleration sensor, shock absorbing springs, a communication interface module, a signal output interface, a signal acquisition and analysis module and an alarm module. The weight and the height of the driver can be assessed through various sensors of the monitoring system installed on a driver seat to realize the real-time monitoring of gravity center moving frequency and respiratory frequency, the early warning of a driving fatigue state is realized and data support is provided for the opening state of an air bag under emergency circumstances through the signal acquisition and analysis module, the alarm module and the communication interface of the air bag, and the output and the saving of monitoring data can be realized through the signal output interface. By using the real-time monitoring system for the state of the automobile driver, the weight and the height of the driver can be assessed, the fatigue state of the driver can be rapidly and accurately judged in real time, traffic accidents are avoided and the injuries caused by the traffic accidents are reduced.

Description

technical field [0001] The invention relates to a real-time monitoring system for the state of a car driver. Background technique [0002] With the rapid development of the modern automobile industry and the increase in the per capita ownership of vehicles, the monitoring of vehicle driving safety has been paid more and more attention. Among the causes of human death and morbidity, traffic accidents rank ninth, and driver fatigue and incorrect ejection of airbags are important causes of road traffic accidents and casualties. At present, the monitoring and control technologies for driver's fatigue driving include: image processing measurement method of monitoring the driver's eye movement, eyelid blinking, mouth opening and closing, body movement frequency, etc. through the camera, accelerator pedal depth monitoring method, brain function status monitoring law, etc. However, in practical applications, there are many problems such as high requirements on the brightness and d...
