The Software Design Of The Multi-threaded Data Recording Device

With the increase of the number of vehicles and the development of relatedpositioning technology, the owners of vehicles tend to pay more attention to the safety ofvehicles. More and more people want to record and track, and schedule the real-timemotion status of the monitored vehicles in a simple and intuitive way.This article designed a data recording device for real-time motion status of theelectric cars. The system is mainly aimed at tracking, managing and monitoring thereal-time motion status of the vehicles through collecting and calculating the real-timeGPS satellite positioning signals and related parameters which were received by thereceiver module of the data recording device, and the received GPS data were processed,saved and updated in the computer monitoring center.The thesis is mainly focused on the concrete realization and related algorithms of themonitoring software part of the multi-threaded data-recording device. A software programbased on multi-threaded communication mechanism is developed in the Visual C++development environment, in order to achieve data reception and display in the softwareinterface. Moreover, the data analysis and partial algorithm is used for the processing ofthe received GPS data, which provides an effective method for the accurate display andpositioning in a two-dimensional map. In addition, the effectiveness of the algorithms andfeasibility of the system is demonstrated by the analysis and comparison of parametersbefore and after using the algorithm. Thus it provides an effective way to solve theproblem of positioning, scheduling, monitoring and safety of the vehicles, and there is alsocertain practical significance for people’s dynamic monitoring of their vehicles.
