【摘要】：伴随新一轮科技革命的浪潮和国家产业升级转型的大趋势,制造业面向信息化和智能化的发展将加速。数控机床作为制造业之重,是现代化生产加工的管件,其发展水平决定了制造业的先进水平。我国虽然已经在制造业生产中普遍使用了数控机床装备,但与发达国家制造业相比,我国多数生产制造企业对数控机床的应用仍不够充分。目前,制造加工车间对数控机床运用存在管理程度低、生产过程不透明、存在信息化孤岛等问题。制造业迫切需要探讨如何建立完善的数控设备监控管理系统,提高设备管理效率。针对目前数控机床在国内的应用现状和发展趋势,本文以西门子SINUMERIK 840D sl数控机床的控制系统为研究对象,研究基于开源PLC通讯类库的数控机床通信技术,并开发了数控机床状态监控系统对相关技术进行了测试验证。本文主要工作如下:首先,本文研究了西门子840D sl数控系统的硬件系统与软件系统的特点,包括硬件架构方式、硬件连接通讯方式和数控系统数据定义类型与功能作用、840D sl数控系统的二次开发功能支持,为建立针对840D sl数控系统的数据采集通信方案做准备。其次,本文分析了840D sl数控系统现有二次开发功能对数据采集通信功能实现的不足之处。结合当前数控设备PLC应用及PC-PLC通讯技术发展的基础上,本文提出了基于PLC数据通信实现对数控机床的数据状态采集和控制。通过分析PLC通讯协议和监控系统开发的特点,本文提出采用合适的第三方通信组件作为设备通讯的底层基础。最后,在充分分析研究选择Snap7第三方通讯类库实现对840D sl数控系统PLC数据通信的可行性基础上,通过分析数控机床在生产实际中的数据采集和状态控制需求,本文设计了基于PLC通讯基础上的分布式DNC数控机床状态监控系统。根据设计需求特点规划了系统架构、数据库架构、应用程序功能实现方式等,并利用840D sl数控机床实验台进行了系统测试,验证本文提出思路的技术可行性。
[Abstract]:With the new wave of science and technology revolution and the trend of national industrial upgrading and transformation, the development of manufacturing industry towards information and intelligence will be accelerated. As the heavy of manufacturing industry, CNC machine tool is the pipe fittings of modern production and processing. The level of development determines the advanced level of manufacturing industry. Although China has widely used CNC machine tools in manufacturing production, but compared with the manufacturing industry in developed countries. The application of NC machine tools in most manufacturing enterprises of our country is still insufficient. At present, the management of NC machine tools in manufacturing workshops is low and the production process is not transparent. The manufacturing industry urgently needs to explore how to establish a perfect CNC equipment monitoring and management system to improve the efficiency of equipment management. In view of the current application status and development trend of CNC machine tools in China. In this paper, the control system of Siemens SINUMERIK 840D SL CNC machine tool is taken as the research object, and the communication technology of NC machine tool based on open source PLC communication class library is studied. And developed the CNC machine tool status monitoring system to test and verify the relevant technologies. The main work of this paper is as follows: first. This paper studies the characteristics of the hardware and software system of Siemens 840D SL CNC system, including hardware architecture, hardware connection and communication, data definition type and function of numerical control system. The secondary development function of 840D sl NC system is supported to prepare the data acquisition and communication scheme for 840D SL NC system. Secondly. This paper analyses 840D. The deficiency of the secondary development function of sl NC system to realize the data acquisition and communication function. On the basis of the current PLC application of numerical control equipment and the development of PC-PLC communication technology. In this paper, the data state acquisition and control of NC machine tools based on PLC data communication is proposed. The characteristics of PLC communication protocol and monitoring system development are analyzed. This paper proposes to use appropriate third-party communication components as the underlying basis of equipment communication. Finally. On the basis of fully analyzing the feasibility of choosing Snap7 third party communication class library to realize 840D SL NC system PLC data communication. By analyzing the demand of data acquisition and state control of NC machine tool in production practice. In this paper, a distributed DNC CNC machine tool condition monitoring system based on PLC communication is designed. According to the characteristics of the design requirements, the system architecture, database architecture, application function realization mode and so on are planned. The system test is carried out by using 840D SL CNC machine tool test bench, which verifies the technical feasibility of the idea proposed in this paper.
