Description

一种智能手机与智能车机互联及控制的方法
技术领域
本发明涉及智能手机和智能车机技术领域，尤其是涉及一种智能手机与智能车机互联及控制的方法。
背景技术
在现在的生活中，随着手机功能的日益强大，人们对手机的依赖越来越深，日常工作生活都已离不开手机。而在互联网的大环境下，汽车智能化将是未来很长一段时间内不变的话题，越来越多的车企开始在汽车中安置尺寸越来越大的屏幕，以满足用户更多的娱乐需求。于是两个屏幕的结合成为了一种不可避免的趋势。
目前市面上有许多通过无线连接将手机屏幕镜像到车机屏幕的方案，但都只能做到镜像屏幕或者对单个app镜像，对手机的操作还是得在手机上进行，对车机屏幕操作并不能控制手机，并且无线连接存在不稳定及传输速度慢的问题。
鉴于人们在车辆中的一些手机使用需求，例如导航，大屏的观看和操作会更加方便直观，通过有线连接传输速度会更快更稳定。因此需要一种可以在车机屏幕操作手机屏幕的稳定的解决方案。
发明内容
本发明的目的是提供一种智能手机与智能车机互联及控制的方法，其具有在车机端控制手机端并且通过有线连接实现高速、稳定的数据传输的效果。
本发明的上述发明目的是通过以下技术方案得以实现的：
一种智能手机与智能车机互联及控制的方法，包括将手机端与车机端通过数据线连接，包括以下步骤：
手机端：首先，手机端与车机端通过私有协议建立通信连接；然后手机端实现投屏服务，该服务利用android的MediaCodec类以及VirtualDisplay类去读取Android的屏幕流，再转化为H264视频流，将视频流通过Socket传输给车机端；最后，手机端接收到车机端传回的坐标后，做出相应的响应；
车机端：首先，车机端在检测到设备接入时，主动弹出连接提示，用户同意后与手机端建立连接；然后，车机通过Socket接收手机端传过来的图像数据信息，然后解压缩显示车机屏幕上；最后，当用户点击车机屏幕时，获取点击的坐标，通过比例换算转化成实际手机分辨率的坐标，再通过Socket将坐标值传回给手机端。
综上所述，本发明的有益技术效果为：
手机端与车机端之间通过数据线互联，提高了数据传输的速度和稳定性；通过获取Android手机的屏幕视频流并通过H264进行编码传输给车机端，让画面显示的更加流畅；通过Socket接收Android 客户端传过来的图像数据信息解压缩显示到车机端上面，当用户点击车机端屏幕时获取点击的坐标，通过比例换算转化成实际Android真机的坐标，然后Android图像的变化再通过Socket实时传输给车机端记住坐标系变化，实现了车机端反向控制手机，驾驶员操作更为便捷。
附图说明
图1是本发明实施例的整体结构示意图。
具体实施方式
参照图1，本发明公开了一种智能手机与智能车机互联及控制的方法，首先，手机端实现私有协议及截取屏幕的功能，然后车机端实现私有协议，展示传屏数据，截获屏幕坐标及转换坐标的功能。将手机与车机用USB线连接在一起，车机端在检测到设备接入时，主动弹出连接提示请求，手机端提示是否屏幕共享。用户点击同意后，车机端与手机成功建立连接，车机屏幕上会展示手机目前的画面。车机屏幕上点击对应区域，会在手机屏幕上有相应的响应，同时车机屏幕上的显示也会随着手机画面显示而变化。
利用android的MediaCodec类以及VirtualDisplay类去读取Android的屏幕流，然后转化为H264视频流，实现屏幕的截取。将视频流压缩编码后通过Socket传输给车机端，车机端接收手机端传输的视频流后解压缩并显示在车机屏幕上，实现投屏。
在车机屏幕上点击对应区域时，在车机端根据比例换算进行坐标转换，变换为手机端坐标，发送坐标值至手机端，手机端接收坐标并相应。响应后手机端页面更新，重新编码传输视频流，通过Socket发送更新后页面编码视频流至车机端，车机端接收后解码显示。不断传输和回传，实现手机端与车机端的互联和控制。
本具体实施方式的实施例均为本发明的较佳实施例，并非依此限制本发明的保护范围，故：凡依本发明的结构、形状、原理所做的等效变化，均应涵盖于本发明的保护范围之内。
