基于Web的货车检修工序监测系统的研制

介绍了铁路货车检修工序进展监控与管理软件的设计.系统通过Web服务器的串口所连接的无线通信模块与现场的无线手持机通信.主机通过轮询方式查询手持机发送的作业进展信息,利用多线程协调完成通信信息的获取与分析.同时,系统采用B/S模式在浏览器页面能对检修工序进展进行实时监视.在Web服务器端,利用Spring任务定时实现每天工作的启停,以及用Spring编写REST风格的Web服务.在浏览器端,利用AJAX技术实现对Web服务的访问,以及将显示结果在页面上动态显示.Web服务通过Json变换向浏览器传递对象消息.

Development of Truck Maintenance Procedures Monitor System Based on Web

The paper discusses the software design of the train repair procedure monitoring and management.In the monitor system,wireless communication is applied for the data transmission between the wireless handsets and communication module connected with the web server serials.Then the host computer inquires work progress from handsets through polling,and the acquisition and analysis of communication information is fulfilled through multi-threaded coordination.Meanwhile,the system realized by B/S mode carries out the real-time monitoring maintenance process in the browser page.On the Web server,the Spring is used to program daily task start and stop in REST style Web service.While AJAX technology is adopted to achieve access to the Web service and the dynamic display of the results on the page,the object message is transmitted to the browser by Json transform.
