从串口读取，并解析NMEA格式的GPS数据的程序。将解析后的数据显示到界面上。需要和发送端的程序配合使用。-read from the serial port and analytic NMEA GPS data formats procedures. Analysis of the data shows that the interface. Needs and transmitter used in conjunction with the procedure.

串行通信接口标准经过使用和发展，目前已经有几种。但都是在RS-232标准的基础上 经过改进而形成的。所以，以RS-232C为主来讨论。RS-323C 标准是美国EIA(电子工业联合 会）与BELL等公司一起开发的1969 年公布的通信协议。它适合于数据传输速率在0～ 20000b/s 范围内的通信。这个标准对串行通信接口的有关问题，如信号线功能、电器特性 都作了明确规定。由于通行设备厂商都生产与RS-232C制式兼容的通信设备，因此，它作为 一种标准，目前已在微机通信接口中广泛采用。-Serial communication interface standard through the use and development, now has several. However, in the RS-232 standard on the basis of an improved formed. So to the main RS-232C for discussion. RS-323C standard is the United States EIA (Electronics Industry Association) and BELL, such as the development of the company in 1969 with the publication of the communication protocol. It is suitable for data transfer rate at 0 ~ 20000b/s within the scope of communication. The standard serial communication interface of the relevant issues, such as signal line features, electrical characteristics have been clearly defined. Because of prevailing production and equipment manufacturers have standard RS-232C compatible communications equipment, t

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
