| With the increase of vehicles, road safety is a serious problem, bad traffic accident in which the driver’s driving behavior leads to even more uncommon. How the driver’s driving behavior in real-time monitoring has become a priority. My job was design and implementation of the driving behavior of real-time monitoring subsystem in the fleet management system when I worked as a traineeinthe Beijing Jingwei Hirain Technologies Co.Ltdlnternet of Vehicle and automotive aftermarket department.The subsystem includes:real-time data processing module, driver behavior analysis calculation module, data storage module, Real-time monitoring display module.It is involved in system design, development, testing, summarized as follows:(1) Participated in and completed the system requirement analysis. In-depth studiedof the characteristics of the fleet vehicle signals, calculated and compared to the traditional way of computing and the stream computing, combined with the business requirements of the system, Iparticipated inpreparationof the requirements documents.(2) Participatedand completedof the system topology design and software architecture design. Based on the industry’s popular real-time processing of the big data solutions, combined with the characteristics of real-time monitoring of business, I engaged in the planning and design of real-time data processing platform topology, as well as for the design of streaming data computing. I also involved in software architecture design of the Real-time monitoring display part.(3) Participatedin realization of the relevant module. Including:real-time analytic signal ofvehicles, driving behavior in real-time computing, fast storage of the big data, and the Web monitoring of vehicle-related signals and driving behavior.(4) Wrote the unit test code of relatedmodule and test. Also did the stress testand analysis the result.The system architecture design is reasonable.It can support the 1000 car to send the signal real-time processing.The monitoring performance is good, delay time is small.The bad driving behaviorjudgment and the vehicle travel route is accurate. The system not only provides the driver behavior and vehicle real-time monitoring, but also ensure the transport be safe, high efficient, energy-efficient. |
