vb串口使用简介,对初学vb串口编程的人有帮助的。-vb use profiles for beginners vb serial programming of help.

云台根据其回转的特点可分为只能左右旋转的水平旋转云台和既能左右旋转又能上下旋转的全方位云台。一般来说，水平旋转角度为0°～350°，垂直旋转角度为+90°。恒速云台的水平旋转速度一般在3°～10°/s，垂直速度为4°/s左右。变速云台的水平旋转速度一般在0°～32°/s，垂直旋转速度在0°～16°/s左右。在一些高速摄像系统中，云台的水平旋转速度高达480°/s以上，垂直旋转速度在120°/s以上 -Yuntai rotation in accordance with its characteristics can be divided into only about the level of rotation and can rotate around Haeundae rotating up and down while rotating omni-directional PTZ. In general, the level of rotation angle 0 ° ~ 350 °, vertical rotation angle for+ 90 °. The level of constant rotation speed Yuntai generally 3 ° ~ 10 °/s, the vertical speed of 4 °/s or so. The level of variable rotation speed Yuntai generally 0 ° ~ 32 °/s, vertical rotation speed 0 ° ~ 16 °/s or so. In some high-speed camera system, the level of Yuntai rotating at speeds of up to 480 °/s or more, vertical rotation speed 120 °/s over
