Beidou Navigation Entertainment System Based On Driving Recorder Function

The Beidou navigation voice entertainment system with recorder function is an in-vehicle electronic device installed in the car.It integrates Beidou navigation function,voice entertainment and driving record function.The system can display the current road traffic condition while recording the vehicle running status in real time,reminding the driver to change the route in advance to avoid the congested road section which can save time and avoid traffic accidents;The recording function of Beidou navigation voice entertainment system can record the occurrence process of accidents,and the video information recorded can be used as evidence for the traffic police department to deal with traffic accidents,so as to objectively protect the rights and interests of victims,avoiding the incident of bumping the porcelain and the occurrence of unfair judgment of the cause of the accident.The goal of this article is to develop and design a Beidou navigation voice entertainment system with the function of driving recorder,which realizes the functions of voice entertainment and driving record while enjoying the navigation and position service.This article mainly introduces the hardware design and software framework design of the Beidou voice Navigation System with the function of the recorder,It introduces the relevant hardware design guidelines and design concepts that meet the requirements of vehicle regulation certification,and deeply studies the problems found in the design test stage and the ideas and methods to solve the problems.The Beidou navigation and voice entertainment system designed in this paper not only has the function of the aftermarket recorder,but also integrates the corresponding functions such as vehicle navigation and vehicle voice entertainment.The system takes the ARM minimum system as the core and uses the relevant car gauge chip and module to construct two subsystems,namely Beidou navigation voice entertainment system and driving recorder system.The Beidou navigation voice entertainment system receives satellite data through the vehicle antenna,and the satellite data received by the Beidou processing module is initially compiled and sent to the microcontrollers,and the data is further analyzed by the microcontrollers,and transmitted to the core ARM processing module.After the ARM processing calculation,the current position information is displayed intuitively in the map,and the position and navigation function is realized by corresponding application software APP algorithm.With a powerful information network,the network,the recorder system finally become a management system which can record and monitor the vehicle information real time and provide scientific and reasonable dispatching for vehicles,to ensure it plays an indispensable role in modern road traffic safe transportation and efficient logistics dynamic operation management.This article introduces the organizational framework of Beidou navigation voice entertainment system in detail,and describes the functions of each part in detail,and introduces the main framework.Finally,the function to be completed by the Beidou navigation voice entertainment system are realized.
