Open To The Database As The Core Coordinate Measuring Machine Control System Research And Development

Coordinate Measurement Machine (CMM) is a kind of new precision measurementinstrument in latest 30 years. It has been widely used in the field of mechanism, electron,mobile and aviation because it is currency, widely measuring scope, high precision,good efficiency.Now CMM develops fastly at home and aboard. But CMM's year number isdiminutive. and tailor-made control system is in the important status. In the conditionCMM has open, currency and flexible develops slowly.In this paper, we mainly advance a kind of CMM control system idea whosenucleus is database, and analyze the constitutes of database and nucleus of database. Atthe same time, we design the software and hardware about this system, and analyze allkind of numeration in the control system, advance new viewpoint. In the side ofhardware circuits, we discuss the way of raster signal subdivision, advance new designscheme, and discuss the hardware structure of count card which is the nucleus of system.We adopt a lot of new technology At last, discuss a lot of problem about real-timeindustry control under Wndows95 with detail and solve the timing interpolation andgathering data.As a result. It is a new way to use database controlling CMM under windows95, hasgeneral significance in numeric control, machine tool and other brainpower mechanismelectron facilities control system.
