摘 要：構(gòu)建了一種基于RT-Linux操作系統(tǒng)的坐標(biāo)測量機(jī)開放式控制系統(tǒng)。該系統(tǒng)利用RT-Linux作為操作系統(tǒng)，以模塊化方式實(shí)現(xiàn)了坐標(biāo)測量機(jī)的運(yùn)動(dòng)控制、相關(guān)I/O控制、測量數(shù)據(jù)采集和人機(jī)界面顯示等功能，并且這些模塊完全開放，從而使控制系統(tǒng)具有互操作性、可移植性、可縮放性和可互換性，大大提高了坐標(biāo)測量機(jī)控制系統(tǒng)的適應(yīng)能力。

Abstract: An open controlling system based on RT-Linux operating system was constructed for coordinate measuring machine（CMM）. This open controlling system achieved the functions of motion control, related I/O control, measuring data acquisition, human-machine interface display, and so on by modularizations with RT-Linux operating system. And these modules were completely open. Thus, the controlling system possesses many features such as interoperability, portability, scalability and exchangeability. All those improved the compatibility of CMM control system greatly.
Key words: Open; Coordinate measuring machine; RT-Linux OS; Embedded
