基于Java 3D的激光微造型机远程操作与控制系统研究
|
摘要
随着计算机、通信和网络技术的发展,制造系统正向着柔性化、智能化、网络化方向发展。同时,由于人们环境意识的增强,创造宜人化生产环境成为制造系统发展的另一个重要方向。数控设备作为制造系统的核心装备,是反映企业生产能力和生产水平的一个重要指标,因此,实现数控设备网络化远程操作与控制成为制造业未来发展的重要趋势。
首先,详细介绍了激光微造型机的整体结构、控制系统原理、以及控制系统的硬件实现,在此基础上,根据激光微造型机的实际加工需求,将远程操作与控制系统功能模块划分为五部分:系统信息、任务管理、安全管理、远程操作与控制、在线交流。
其次,对构建远程操作与控制系统框架所涉及到的计算机网络理论体系进行了讨论,并对基于Client/Server和Browser/Server模式的远程操作与控制系统进行了对比,提出了基于Browser/Server模式的激光微造型机网络化远程操作与控制系统的总体框架。系统分为三层:客户层、中间层、和现场设备层,客户层采用嵌入浏览器页面的Java 3D模型代替传统的视频图像,为用户提供友好的远程交互操作界面,中间层应用服务器配置系统的控制逻辑,现场设备层负责机床运行状态的数据采集和指令执行。
最后,详细阐述了激光微造型机远程操作与控制系统开发过程中的关键技术及其具体实现方法:系统采用Java 3D技术对激光微造型机进行了三维可视化建模;采用多线程技术实现了激光微造型机运行状态数据的采集和存储;通过Applet-Servlet-Database模式完成了客户端、服务器和数据库之间分布式对象的数据通信;运用Java本地接口方法实现了激光微造型机远程操作与控制。运行测试结果表明,该系统可以满足实际应用的要求。
With the developing of computer technology, communication and network technology, manufacturing systems are undergoing the simultaneous trends of flexibility, intelligence, and networking. Meanwhile, for the enhancement of people's environmental consciousness, man-beneficial has been one more trend for the manufacturing system. Computerized numerical control machine tools are regarded as the key equipments of the manufacturing systems, and which stand for the productivity and level of the enterprise. It will be an important trend for the manufacturing industry to make the CNC machine tools be operated and controlled remotely in the future.
Firstly, the thesis expounded the overall structure, control system principle, and the hardware implementation of the control system of the laser micro-texturing machine. On the basis, according to the practical manufacturing demand, the function module of remote operation and control system was divided into five parts, and they were system information module, task management module, safety management module, remote operation and control module and online communication module.
Secondly, the thesis discussed the theoretical system of computer network, which was referred to the construction of the remote operation and control system, and comparing with the remote monitoring and control systems in Client/Server and Browser/Server mode, the thesis proposed the overall framework of Browser/Server-based networked monitoring and control system on the laser micro-texturing machine. The system was divided into three layers, client layer, intermediate layer and field-devices layer. In this system, the browser embedded with Java 3D models offered cliens friendly and interactive interfaces. The application server in the intermediate layer answered for the control logic of the system. The field-devices layer presided over the data collecting of the running status and excuting the demands.
Thirdly, the thesis expounded key technologies and the specific realization methods in the whole developing process of the system development. It adopted Java 3D technology to implement the 3D visualization modeling of the laser micro-texturing machine, and multi-thread technology to accomplish data collecting and storing for running status. Applet-Servlet-Database mode was to accomplish the data communication between distributed objects of client, server, and database, and Java native interface was used to realize the remote monitoring and operation on the laser micro-texturing machine. Testing results showed that the system could satisfy the practical application.
