摘　　要：浏览器里的Web应用和计算机的串口硬件进行通信时,需要针对不同的浏览器开发不同的插件。采用HTML5内置的WebSocket技术和QT开发框架,通过WebSocket协议连接本地服务,并通过本地服务绑定串口完成全双工通信的方案,实现了跨浏览器的Web应用与客户端计算机串口通信的技术,解决了为不同浏览器产品及版本开发多种插件的问题。经过测试验证,达到了预期目标。In the communication of Web applications in browsers with the computer’s serial hardware,it is required to develop the different plug-ins in different browsers.The full-duplex communication scheme is implemented by using WebSocket technology provided by HTML5 and QT development framework,connecting local service with WebSocket protocol and bounding the serial device with local service.The across-browser communication is realized between Web application and computer serial communication,which solves the problem of developing different plug-ins for different browser products and versions.The test results show that it achieves the expected goal.
