A new air artillery counter
Office of the analog signal. Data Processing Module - the data collection (continued on page 4) * Fuxing Zhen, male, students in 1958, Lecturer, Bachelor of Engineering, the main weapons in the air teaching and research work 14 · e. Profile of automatic analysis with the evaluation function. 4 error correction CMM in manufacturing, there is space geometric error, positioning error and nonlinearity error, referred to as systematic error, which affects the accuracy of coordinate measuring machines. Systematic error is generally divided into fixed and variable error of error, the error value is obtained through the corresponding experimental methods, and be eliminated by amending compensation. To do this,[link widoczny dla zalogowanych], \Indication error correction before and after the contrast in Figure 5. - \ / A V. - \,. . * * * 'M) 2OO4006008001000 Figure 5 shows space network error after error correction of the contrast can be seen from Figure 5, the amendment before the accuracy of 65/zm, the revised accuracy of 12 /. tm. Accuracy is greatly improved. 5 Experimental results according to GB/T16857.2-1997 ((Part 2: performance evaluation of coordinate measuring machines \axis straightness 10tnnx, Y, z axis perpendicular to each other degrees 10pan (on the next page 14) sent the signal filtering module, conversion, calculation and other aspects of treatment, the results based on an effective signal. Display Module - according to need to display different information (such as payload, the remaining number of artillery shells, gun cumulative number of shots, and system self-test results, etc.). When the gun switches connected after the power supply will be connected to the counter, the counter is automatically self-test if fault counter automatically suspended. If there is no failure, display self-test results, 1 minute and changed to the display load of bombs. then you can enter as payload. If you do not enter the payload,[link widoczny dla zalogowanych], the counter will last the number of firing artillery shells left after the show as the payload. gun fire, the sensor output pulse signal input via the interface the host computer,[link widoczny dla zalogowanych], and then through the process identification,[link widoczny dla zalogowanych], treatment and operations, and calculate the number of remaining rounds, give it away display display. When flying 4 axial length measurement repeatability 14/.tm measure the maximum indication error: x-axis 14.6tmaY 8.1/.tmz shaft axis of a maximum length measurement of a 16.2tma indication error of measurement : 23.6tma measurement error: 12tma all test results meet specification requirements. 6 Conclusion In summary, \coordinate measuring machine. It implements the following technical innovation: enhancing the level of arm rigid body special. The agency increased the rigidity of the horizontal arm, and the deflection caused by the deformation of the regulation, effectively ensure the stability of cantilever measurement system sex. The technology for the domestic unique. Space Network Application Error Correction Method. The instrument used successfully network error correction method of space, significantly improve the measurement accuracy. the compensation method used in this data correction cantilever measurement system , is a national first position 0. host suspension device. The device can move the host into a rectangular coordinate system, the measurement is vast, open, convenient to a variety of measurement requirements. floating coordinate measuring machines for the domestic unique . \and implementation of industrial products. References 1GB/T16857.2-1997 (Part 2: performance evaluation of coordinate measuring machines \into the data storage module to facilitate air, ground crew information. 4 Conclusion The high rate of fire gun I play the successful development of counter space to effectively solve the target problem of training and operations. The device has a visual display clear, complete and accurate records etc., by the use of personnel at home. Reference 1 Mullan. microcomputer principle and interface technology [M].
