[Abstract]:Numerical control technology is a national strategy technology, numerical control system field bus is the core key technology of high-grade numerical control system, foreign high-grade numerical control system has been widely used, but domestic numerical control system is still not involved. The development of high-grade CNC system in our country is seriously restricted. Therefore, it is of great significance to develop the field bus and bus signal monitoring device with independent intellectual property rights, which can monitor the field bus in real time, high reliability and full information. The main contents of this paper are as follows: a system design scheme based on NCUC-Bus (NC Union of China Fieldbus) bus monitoring platform is proposed. The architecture and network topology of NCUC-Bus bus are analyzed, and the communication mechanism and real-time performance of bus monitoring platform are studied. Technical features of reliability and full information. The high performance ARM FPGA is used as the core processing chip to form the hardware platform, which supports the communication of NCUC-Bus fieldbus, realizes the data acquisition, processing and analysis of NCUC-Bus fieldbus, and supports the application of man-machine interactive display interface and Ethernet interface. This paper studies the construction and transplantation of embedded WinCE operating system of bus monitor platform, analyzes the process of bus data processing, realizes the driver of stream interface for bus communication and the design of embedded bus monitor application program. The data frame structure and the basic link of the bus link are analyzed. The experimental platform of fieldbus monitoring is built, and the function test of the bus monitoring platform is carried out. The characteristics of the whole information of the bus monitoring are verified, and the real-time test of interface delay time and ARM interrupt response are carried out. The reliability of the bus monitoring platform is verified and analyzed. The developed monitoring platform based on NCUC-Bus bus has been applied and verified in the high-grade CNC system of Huazhong NC, and its validity and reliability have reached the design requirements.
