摘要
采用STC12C5A60S2单片机作为系统控制单元,由其PCA定时器产生PWM信号控制云台水平和垂直方向的舵机,将旋转编码器与舵机同轴相连,单片机定时器0与定时器1对水平和垂直旋转编码器转动产生的脉冲分别进行计数,确定当前角度,以控制吊舱中摄像装置进行全方位监测。介绍了控制模块硬件结构及软件实现。通过实际系留飞艇的验证,此模块能够在地面站的控制下,控制云台摄像机进行全方位地面监测。
By adopting STC12C5A60S2 as a system control unit, generating PWM signal by PCA timer to control horizontal and vertical steering gears on PTZ, we connect rotary encoder coaxial to steering , Timer 0 and Timer 1 of single chip count the pulses that generated by turnning rotary encoder in horizontal and vertical directions to determine the current point of view, in order to control the camera device in pod to monitor all-round. This paper describes hardware and software of the control module. Veri- fied by actual tethered airship, this module can control PTZ camera to monitor full-ground under the control of ground station.
