Design Of Human-machine Interaction Software On V2X-based Vehicular Terminal

In the context of the rapid growth in the number of cars,traffic accidents caused by cars occur frequently.In order to avoid the huge losses caused by traffic accidents,V2X(Vehicle-To-Everything)car networking technology has been rapid development.V2 X car network for vehicle driving safety warning,to avoid congestion and dangerous sections,improve traffic safety,reduce the occurrence of traffic accidents.The existing V2 X technology can solve the vehicle and vehicle,vehicle and non-vehicle communication problems between the realization of V2 X communication.As the application of V2 X technology,bring a lot of new applications,real-time response due to V2 X communications brought human-computer interaction problems,such as real-time,customizable choice.In this regard,this paper through the study of V2 X communication technology,to achieve the typical application of V2 X communication human-computer interaction and customization,to solve the V2 X communication after the human-computer interaction.The main work of this paper includes the following aspects:First of all,this paper designs the system framework.According to the functional requirements of the system,the network topology of the system is analyzed and designed,and the whole network architecture is built through the wifi network and the mobile cellular network with V2 X terminal,human-computer interactive terminal and information service platform.Based on the system network architecture,to achieve the software to run the communication environment.The software uses MVC software framework design mode,the functional code and business display interface time-sharing,improve the program reusability and maintainability.Based on the system architecture design,the software business function becomes easy and reliable,and the application functions such as vehicle position display,collision prevention warning,fatigue detection,traffic light display,intercourse short message and emergency message are realized.Secondly,this paper designs the commonality of V2 X human-computer interaction.The key issues are the following:(1)Heterogeneous network communication stability and implementation of humancomputer interaction.According to the needs of the system network connection,the connection between the human-computer interaction terminal and the V2 X terminal is analyzed and researched from the hardware connection and the software connection,and the point-to-point connection method and the real-time monitoring method are summarized.Service connection between the service platform,this paper uses the detection of reconnection method.For different connection methods,the use of heterogeneous connection method,and ultimately achieve a reliable and stable communication connection.(2)human-computer interaction model and implementation method.Event-object model(E-O model)is used to describe the human-computer interaction mechanism.Through the vehicle information,roadside information and other vehicle information as the event in the human-computer interaction model,the corresponding interactive object is triggered by the event through the service control module.In the software design,the interactive object can be the corresponding business function display interface,or the entity in the communication.Events lead to interactive activities,the object of interaction is the activities of the bear,time-driven,object as the core,with object-oriented style,but also take into account the independence of the principle of dialogue and semantic feedback requirements.(3)human-computer interaction can be customized design.According to personal preference,the software application interface can be defined by the user's own display location.Users only need to configure the function menu preferences,you can achieve the application interface of the heart show.Finally,this paper designs and develops the typical application of human-computer interaction.Vehicles through the V2 X communication can be obtained vehicle information,such as the body speed,direction,location information,and the vehicle around the information,including road test information,other vehicle information.Based on the system network construction,human-computer interactive terminal can display vehicle information and vehicle information in real time.Through Baidu map coverage method,application interface design,and push the news communication and reality,and ultimately to achieve the application display.
