Embodiment Construction

[0018] The driver maintains an upright sitting posture according to the instructions of the alarm module 10 at the beginning of driving, and evaluates the driver's height and weight through the pressure sensor 1 and pressure sensor 5, providing data support for fatigue driving monitoring and the size and direction of airbag opening in an emergency. During the driving process, the three-way acceleration sensor 6 and the three-way acceleration sensor 9 are collected simultaneously, and combined with the pressure sensor 5, the moving frequency of the center of gravity of the driver's up, down, front, back, left, and right and the sag of the body posture during driving are obtained. In this situation, the driver's fatigue degree is analyzed. Simultaneously, the respiration sensor 2 monitors the driver's respiration rate in real time, and judges the fatigue state of the driver through the variation of the respiration rate. The driver's fatigue status information obtained by the acc...

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...
