导航装备轴角测试方法的研究

basic way ofmeasuring the position angle signal for sychrowas introduced,The scheme of axis angle test based on synchro and with high performance to price ratio is designed,Existing angle measurement equipments cost highly,which is a disadvantage at the large quantity for production,In order to meet the popular needs,In this paper,C8051F064 and TMS320F2812 are regarded as two chips with high performance to price rat,C8051F064 own two independent 16-bit A/D converter module,its conversion rate can reach 1M/s,TMS320F2812 with high-performance 32-bit CPU and 128K of Flash has SPI, SCI,McBSP serial interface and other peripherals.C8051F064 is used in the design of the perspective of signal A /D conversion and a simple filter to deal with, and then the signal is sent to the TMS320F2812, its signal is further processed in it. the design is the use of the method of the cut section coding for the ratio of sine to cosine combined with the look-up table encoding method,it s electric circuit is simple,the cost is low,and the function is easy to expand,the general need for experiment of angle measurement is satisfied.
