[Abstract]:With the continuous development of computer technology, network technology and sensor technology, a new round of science and technology has emerged in the 21st century. Following the publication of the "Industry 4.0" strategy by Germany and the national strategic plan for advanced manufacturing industry put forward by the United States, China published the "made in China 2025" strategy in 2015. Intelligent manufacturing based on the deep integration of industrialization and information technology has become the breakthrough point and the main direction to build the new competitive advantage of the national manufacturing industry. The digital, networked, intelligent and humanized manufacturing industry is the core goal of intelligent manufacturing. The networked monitoring of NC equipment is the basic link of intelligent manufacturing, which realizes the networked real-time monitoring and management of NC equipment. It can effectively improve the utilization rate of CNC equipment, reduce the failure rate of machine tools, and promote the management level of enterprises and the core competitiveness of enterprises. The purpose of this paper is to study a general networked real-time monitoring and management system for CNC equipment. Based on the analysis of the actual demand of enterprise network and information, a new distributed information collection and centralized management system solution based on PLC, numerical control, computer and wireless transmission technology is put forward. And I-DNC equipment network monitoring system is designed and developed. The main contents of this thesis are as follows: 1. According to the actual demand of enterprise equipment networking, combined with the open interface of NC machine tool and the information that can be collected, the solution of bottom data acquisition is put forward. Through the RS232 communication interface of CNC machine tool, the functions of uploading, downloading and DNC on-line machining are realized. The internal machining data is collected by macro command feedback, and the current signal of each electric axis of CNC machine tool is collected by external current sensor. The SMART200 PLC is used to connect with the PLC inside the machine tool. I / O output signals can be collected, such as tool changing signal, coolant switch, machine tool working state, etc. Based on the analysis of the existing communication modes of CNC machine tools, the communication scheme of CNC workshop network based on industrial Ethernet PLC and wireless serial port server is put forward. In this scheme, Modbus-RTU communication protocol is used to realize the communication with current sensing, and the current situation of each electric shaft of NC machine tool is collected in the process of machining. OPC communication technology is used to realize the communication connection between PLC and the upper management system. The PLC has strong anti-interference ability and stable communication. The SmartLine1000IE configuration software is used to compile a good human-computer interactive machine tool state monitoring interface. Through wireless serial port server, the communication mode of serial port to Ethernet is realized, which solves the problems of difficult wiring and short transmission distance of serial port in engineering center, realizes the communication between i-DNC management system and machine tool effectively, and achieves the purpose of monitoring NC machine tool. Based on the object-oriented programming method, the monitoring system is developed by using the modular design idea. This software is based on Windows operating system, adopts WPF technology under. Net platform, uses C # programming language VS2010 development tool to develop machine tool monitoring system, and uses SQL server 2008 database to store and manage the relevant information inside the monitoring system. The research results show that the system can monitor the machining status of machine tools and collect processing information in real time. It has the characteristics of stable communication, reliable analysis results, strong anti-interference ability, easy management, good expansibility, and so on. It has good application and promotion value.
