【摘要】 坦克炮塔试验台由上位PC机、MAX197和AT89C52及软件组成。PC机以无线方式与AT89C52通信。数据采集以AT89C52单片机为主处理器,P2.7作片选信号,通过控制字的写入初始化MAX197,以确定其采集转换通道、量程和极性等,输出无符号二进制或二进制补码数据。其控制和通信软件用C开发。更多还原

【Abstract】 The test-bed for tank gun-control system consists of upper PC, MAX197, AT89C52 controller and software. The upper PC communicates with AT89C52 controller by wireless mode. AT89C52 controller is the key controller of the data acquisition system. P2.7 pin of AT89C52 used as chip selecting signal, MAX197 is initialized through writing control byte, to confirm its input channels, input voltage ranges and polarity. The output data format is unsigned binary in unbipolar mode or twos-complement binary in bipolar mode. The control and communication software is programmed with C Language.更多还原
