Embodiment Construction
[0067] according to Figures 1 to 7 As shown in any figure, on the basis of the high-speed ball body, it specifically includes:
[0068] The high-speed dome body is equipped with a monitoring circuit for the video signal of the integrated movement. The circuit uses LM1881 to synchronize and separate the video signal. The obtained line synchronization signal VIDEO_CHK is sent to the external interrupt IO of the microcontroller for monitoring. When the high-speed dome system has video The signal and synchronization signal are separated by LM1881; the external interrupt of the single-chip microcomputer can regularly monitor the falling edge of the synchronization head; when the video of the high-speed ball system is lost, the synchronization signal disappears; the single-chip microcomputer fails to monitor the synchronization head regularly, and it is confirmed that the video signal is lost;
[0069] The high-speed ball body is equipped with a temperature acquisition circuit. The...
