Drunk driving monitoring system and method based on GPS navigation and positioning and NB-IOT technology

Abstract

The invention discloses a drunk driving monitoring system and method based on GPS navigation and positioning and the NB-IOT technology. The drunk driving monitoring system comprises a vehicle-mountedcontrol terminal, the vehicle-mounted control terminal comprises: an alcohol concentration sensor for obtaining alcohol concentration information according to exhaled gases of a driver; a GPS module for positioning the location information of a vehicle; a main controller respectively connected with the alcohol concentration sensor and the GPS module for judging the state of the driver according tothe alcohol concentration information obtained by the alcohol concentration sensor, and further judging a driving state of the vehicle according to the location information of the vehicle, when the main controller judges that the driver is in a drunk driving state; and an NB-IOT module connected with the main controller for sending the alcohol concentration sensor and the location information toa public security transportation network according to an instruction sent by the main controller, when the main controller judges that the vehicle is in a driving state. The technical problems of missed detection, delayed detection, false detection, high labor cost, low efficiency and the like in the drunk driving detection are effectively solved.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a system and method for monitoring drunk driving based on GPS navigation and positioning and NB-IoT technology. Background technique [0002] Drunk driving refers to driving a motor vehicle after the driver has drunk alcohol. During the driving process, due to the anesthesia effect of alcohol, the sensitivity of the driver's hands and feet to touch is lower than usual, so that he cannot normally control the accelerator, brake and steering wheel. In addition, the judgment ability of the driver will be reduced, the reaction time to stimuli such as light and sound and the time of instinctive reflex actions will be prolonged, and the coordination function between sensory organs and motor organs (such as eyes, hands, feet) will be impaired. , so that the driver cannot correctly judge the distance and speed. In addition, the driver's vision will be damaged to a certain extent afte...
