    基于SOPC技術的三坐標測量機運動控制核心

    2008-06-19

    摘  要:設計了一種新型的基于SOPC技術的三坐標測量機控制核心。該控制核心以數字脈沖的方式實現三坐標的運動控制和相關I/O接口控制功能。該核心的測量機控制系統以PC機作為上位機,利用串口進行上、下位機的通信,所有對實時性要求高的功能都在片內實現,包括插補運算、測點鎖存和測頭保護等。用SOPC技術開發的坐標測量機控制核心簡化平臺硬件結構,系統具有開放、性能可靠且本身結構緊湊等特點,并且可以靈活的實現定制應用。   關鍵詞:SOPC(可編程片上系統);FPGA(現場可編程門陣列);坐標機運動控制;測點鎖存;測頭保護   中圖分類號:TP311.52;TP273        文獻標識碼:A         文章編號:1672-4984(2008)03-0107-03   CMM motion control core based on SOPC technology   JIANG Zhou, ZHOU Dan-hua, LAN bo   (National Institute of Measurement and Testing Technology,Chengdu 610021,China)   Abstract: A new kind of CMM (coordinate measuring machine) control core was designed based on SOPC (system on a programmable chip) technology. This control core controls the tri-coordinate motion and the functions of the related I/O through the mode of digital pulses. And it takes PC as upper system, used a serial port to communicate between the upper system and the lower system, and all functions needing high speed and real-time were performed in the chip, include interpolation, measuring point latching, probe protecting, etc. The CMM control core based on SOPC technology has simplified the structure of motion controller hardware, and its system has features such as open structure, reliable performance, compact structure, and so on. Thus, this CMM motion control core could be achieved at custom-made applications flexibly.   Key words: SOPC; FPGA; CMM motion control; Measuring point latch; Probe protect   Editor:liyan  ...
