Control Precision Test Equipment Design of an Anti-Aircraft Gun Servo System

Control precision of the anti-aircraft gun servo system related directly to the artillery firing accuracy, and it is a very important item in performance test of the fire control system. In order to test the control precision of an anti-aircraft gun servo system and correct the firing data, the shaft angle conversion circuit and digital signal interface circuit are designed based on the industrial computer platform and the data acquisition module of PCI bus. In that way, software arithmetic of shaft angle conversion based on the general A/D is realized. In the practical application the arithmetic has a good performance.
