In the field of security monitoring, the smart dome camera system can realize 360° full-range monitoring without blind spots, and realize more intelligent monitoring through preset positions, track scanning, guard positions, pattern scanning, alarms, etc. The system has been widely used in the field of security monitoring. The realization of 360° rotation monitoring and some intelligent functions must be realized through slip ring devices; traditional slip rings only transmit electrical signals, and video and control signals are unstable due to the instability of contact resistance, resulting in reduced reliability of the transmission signals and resistance to Reduced interference. Due to the influence of slip ring factors, the transmission rate and bit error rate of the smart dome camera system are difficult to increase. It can only transmit ordinary analog data signals and electrical signals, and cannot transmit high-definition digital signals.
The technical problem that Jiujiang Ingiant wants to solve is to provide a slip ring for the smart dome camera system to achieve more reliable and higher-speed data signal transmission for the smart dome camera system, and to overcome the inability of the smart dome camera system in the existing technology to transmit high definition. Defects of digital signals. The following technical solution is adopted: a slip ring of a smart dome camera system, including a stator, a rotor installed in the stator, an upper wire harness connected to the slip ring on the rotor, a sliding brush in contact with the slip ring on the rotor, and The lower wire bundle connected by the sliding brush is characterized in that the lower optical fiber bundle is fixed at the lower part of the stator, the upper optical fiber bundle is fixed at the central axis of the rotor, there is a gap between the upper optical fiber bundle and the lower optical fiber bundle and they are coaxially focused.
By adopting the above technical solution, in the slip ring of the smart ball camera system, on the one hand, the electric signal is transmitted through the wire to power the smart ball camera and the motion mechanism, and on the other hand, the optical signal is transmitted through the optical fiber to realize the transmission of the image and command data of the smart ball camera. This optoelectronic hybrid data transmission method has the advantages of strong anti-interference ability, higher data transmission rate and lower bit error rate, which meets the needs of the smart ball camera system in the field of security monitoring to transmit high-definition digital signals.
