Monitoring System Design Of Motor Vehicle Driving Based On GNSS Speed Measurement And Drunk Driving Detection

Statistics show that more than half of all deaths caused by drivers' illegal activities involve drunk driving and overspeed.It is not uncommon for the driver to suffer injuries due to drunk driving and overspeed.With the continuous upgrading of automobile technology,the power of the car on the market is getting stronger and stronger,which brings convenience to the speeding of the car.In order to reduce the incidence of such accidents,it is particularly important to detect real-timely drive and overspeed of the driver.Once the detection system discovers drunk driving and overspeed problems,it automatically performs an alarm or even performs necessary vehicle braking to prevent traffic accidents.In this thesis,a monitoring system of drunk driving and overspeed is designed and implemented based on the actual situation of the car driving.When the driver enters the car,he first needs to conduct an alcohol test to detect the alcohol residue in the driver's body.The car is allowed to catch fire after the test passes.When the vehicle is in the running state,the system monitors the vehicle speed through the global navigation satellite system(GNSS)module based on the GNSS speed measurement technology.At the same time,the actual vehicle speed of the vehicle and the safety parameters of the system settings are displayed through the LCD screen.When the vehicle speed is found to exceed the maximum value set by the system,the buzzer starts to alarm and the warning light flashes continuously to remind the driver to decelerate.At the same time,the system can locate the vehicle through the GNSS,and then transmit the alarm position to the duty room through the global system for mobile communication(GSM).At this time,through human intervention,the supervision and management of the driver can be strengthened to prevent the occurrence of safety accidents.The system design scheme not only satisfies the intelligence and network required for anti-drunk driving and ultra-speed system data collection,but also has many advantages such as low cost,high reliability and easy maintenance.Therefore,the system meets the needs of practical applications and has certain practical and promotional value.
