The Design Of The System For Measuring Diameter Of The Gun-Barrel Inside Chamber

A measuring system which can be used to measure the diameter of the Gun-Barrel inside chamber is developed. The paper presents the design idea and implement scheme of the measuring system.Moire principle and photo electricity detect technology are applied in designing the intelligent photoelectric measuring system . In order to realize the system can do the measuring job with automation and intellect , IBM-PC used as controlling and managing system and single-chip microcomputer as the core of the measuring system. Also, the computer assessment of the Diameter error are completed.This system can also be used in the measuring for the diameter of other accessory ,such as holes.
