Monitoring system and monitoring method for dangerous operation behaviors of driver on cloud platform

Abstract

The invention relates to the field of cloud technology, and discloses a monitoring system and a monitoring method for dangerous operation behaviors of a driver on a cloud platform. The monitoring system comprises an on-vehicle end and a cloud-end server. The on-vehicle end is provided with an on-vehicle sensor module, a data acquisition system, a wireless communication module, a GPS receiver, a voice prompting and early-warning system, and a switch unit. Wireless communication technology is used for transmitting acquired sensor data information to the cloud-end server in real time, and furthermore a driver can selectively switch on the switch for realizing the function. The cloud-end server comprises a data storage system, a real-time road condition acquisition system, an expert system and a driving behavior analysis system. According to the expert system, a China national highway geographic information system, a road-side system and a GPS navigation system, the dangerous operation behavior of the driver is identified from the acquired sensor data information through the driving behavior analysis system, and furthermore dangerous behavior alarm information which is output according to decision of the cloud-end server is transmitted to the on-vehicle end and prompting is performed so that a vehicle owner masters the dangerous driving behavior himself in real time.

Description

technical field [0001] The invention relates to the field of cloud technology, in particular to a monitoring system for dangerous operation behaviors of car drivers under the cloud platform. Background technique [0002] With the continuous increase of car ownership, traffic safety has become the focus of restricting the harmonious development of society. The number of deaths caused by traffic accidents in the world exceeds 600,000 every year, and the direct economic loss is about 12.5 billion US dollars. Among these accidents, 70% of catastrophic accidents are related to dangerous driving behavior. Improper driving behavior not only affects the normal traffic order, but also poses a certain threat to the safety of vehicle drivers. Statistics show that when a traffic accident occurs, if the driver's reaction can be half a second faster, 60% of the traffic accidents can be avoided. [0003] In recent years, governments, non-governmental organizations and major automobile co...

Problems solved by technology

[0004] In order to overcome the shortcomings of the existing behavior monitoring system that may cause privacy leakage through camera monitoring, insufficient real-time performance of a single vehicle's autonomous offline judgment, mandatory monitoring that does not follow the owner's subjective wishes, unclear definition of dangerous driving behavior, and lack of voice reminders and early warning functions, first , the behavior monitoring system of the present invention will directly use the existing throttle opening position sensor, steering wheel position sensor and vehicle speed sensor of the car, and add the brake pedal position sensor and steering wheel pressure sensor to carry out behavior monitoring data collection, effectively avoiding the camera The privacy leakage problem that monitoring may cause; Second, the present invention expands the driver's operation behavior monitoring to cloud platform online monitoring, fully utilizes the data resource library (expert system) that cloud server contains a large amount of operation behaviors, improves the real-time performance of operation behavior monitoring , and combined with the real-time road condition data obtained from the real-time road condition acquisition system, the accuracy and effectiveness of real-time monitoring will be further improved; thirdly, the present invention will add a switch unit of the wireless data communication module at the vehicle end, and the driver can choose whether to open or not The data transmission function can effectively avoid the forced monitoring of the driver's operation behavior; fourth, the present invention will clearly define and distinguish the situation of the driver's dangerous operation behavior, mainly including 8 kinds of dangerous operation behaviors: rapid acceleration, sharp turn, sudden braking , snake-like driving, one-handed driving, continuous acceleration, mistakenly stepping on the accelerator and turning in the wrong direction; fifth, the present invention will further add a voice reminder module on the vehicle-mounted end, so that the results of cloud decision-making output can be transmitted to the vehicle-mounted end in real time, reminding driver and make corrections
