[Abstract]:Numerical control machine tools play an important role in the manufacturing and processing industry of our country, promote the development of our country's manufacturing industry, and are of great importance to the development of the whole national economy of our country. However, at present, the technology of domestic machine tools is backward, the development of machine tools is slow and the level of intelligence is not high, so it can not meet the requirements of the development of manufacturing industry at the present stage of our country, nor can it meet the requirements of the development of information strategy for manufacturing enterprises This requires that China's machine tools to constantly improve their overall manufacturing level. With the rapid development of network technology, automation technology and intelligent reasoning technology, networked and intelligent manufacturing is the development direction of the whole machine tool industry, and multi-function embedded terminal system can help NC machine tools to realize network and intelligence. In order to improve the networked and intelligent manufacturing level of NC machine tools, this paper studies the supporting platform and key technologies of intelligent lifting terminal system of machine tools, and realizes the development of prototype system. Verify the correctness of the relevant theory and the practicability of the system. This paper first states that the intelligence level of CNC machine tools in China is backward, the independent intellectual property rights are insufficient, the heavy dependence on imports and the networking and intelligentization of machine tools are of great and far-reaching significance to the whole manufacturing industry of our country. The intelligent lifting terminal, the intelligent lifting terminal system, the supporting platform of the terminal system and its configurable requirements are analyzed, and the framework of the intelligent terminal system supporting platform is put forward and described in detail. Then, the key technology of intelligent terminal system supporting platform is studied. The key technologies include: 1) Information interaction between CNC system and terminal system. In this paper, the realization of information exchange between the mainstream CNC system and the terminal system under the open architecture of CNC system is studied. In this paper, a dynamic configurable .2 (2) technology of information interaction between NC system and terminal system based on C / S model scheme is presented, and the technology of information interaction between machine tool ontology and terminal system is presented. This paper studies the dynamic configurable technology of intelligent lifting terminal system of machine tool based on plug-in and priority based on FCFS hardware interface scheduling to realize data acquisition and control of sensor, intelligent instrument, data acquisition card and so on. The network support technology of intelligent lifting terminal platform for machine tool is studied, including TCP/IP network communication, serial port communication and TCP/IP communication. Then, based on the analysis of the supporting platform framework of intelligent lifting terminal system of machine tools and the research of key technologies, the hardware platform of the terminal system is first built, and then the embedded operating system is transplanted according to the hardware platform. Finally, the key technologies involved in the supporting platform are developed and implemented, and the application program interface is formed for the application layer to call, so as to realize the network and intelligence of intelligent machine tools. Finally, the prototype system is developed and run in a gear hobbing machine bed in Chongqing, which reduces the difficulty of developing the function module of the terminal system, shortens the development cycle, and improves the utilization ratio of the related resources of embedded terminal. For the realization of CNC machine tool networking and intelligence laid a solid foundation.
