According to the problems of long period,difficult attitude adjustment,low level of automation and efficiency about aircraft weight and gravity center measurement,a kind of automation measurement scheme was proposed for aircraft weight and gravity,and a set of measurement control system about weight and gravity was designed and developed.This system was composed of PC and PLC,and combined with the ways of laser ranging,angle sensing detection and servo control.The functions of attitude automatic adjustment,weight automation measurement and gravity center automation calculation,realtime status monitoring display,remote monitoring and controlling were realized.The application shows that this designed measurement device control system changes traditional attitude adjustment,measurement calculation and the ways of analysis and treatment,manual labor intensity is reduced,the measuring efficiency and the level of automation are promoted,system feasibility and safety reliability are verified.
