Vcr Head L Value Detection Sub-file Machine Design

In the digit, network and information society, the electrical control, instrument control, tube control, and information technique have gotten rapid development. To meet the demands of the development, opening PC-based control project has prevailed in the field of the industrial control technique. To meet the demands of the increasing yields of VTR head, a kind of opening auto control inductance rank division instrument that based on PC control.is designed.With the IPC-610 as its controlling processing kernel and 4277A LCR as its measuring terminal, the inductance rank division instrument transmit data through PCL-848, at the same time, to have the single tunnel 100-point continuous measuring ability, it has single shaft traverse motor servo system controlled by PCL-839 and 10-point switch relay group. Furthermore, to operate conveniently and have the ability of selecting heads manually, a 4*5 matrix keyboard and 10*10 matrix LED display circuit are designed. The overall inductance rank division instrument has full function and the design is concise, which can fulfill the duty of the inductance measuring and inductance rank division perfectly.As the inductance rank division instrument has the characteristic of opening and structural hard ware module composition, after it is successfully designed, it has great reference value in the research of many kinds of electrical components measuring instruments in CHMAVC , and make a foundation of flexible utility of PC-BASED industrial controlling project as well as the improvement of yield ability.
