A dome machine cloud platform control system

Abstract

The invention discloses a ball machine pan-tilt control system. The ball machine pan-tilt control system is connected with a plurality of ball machines with video channels; the video channels of a plurality of video channels are connected with a video channel selection circuit, so that breakover video signals in the breakover video channels of the ball machines are transmitted to a display for displaying; a processor receives a pan-tilt operation signal and transmits the signal to a singlechip; a video synchronizing signal split circuit receives the video signals transmitted by the video channel selection circuit, generates a video synchronizing signal and transmits the signal to the singlechip; according to the video synchronizing signal, the singlechip controls and outputs a pan-tilt operation signal to metal oxide semiconductor (MOS) tube superposed circuit for superposing and generating a coding video signal which is sent to the ball machines through the video channel selection circuit, and the ball machines decode the signal to split the pan-tile operation signal for executing corresponding operation to the pan-tilt. By using the ball machine pan-tilt control system, the video signals and the pan-tile operation signal can be transmitted at the same time, so that wires and cost of wiring and labors are saved, and the complexity of a security-protection wiring space is reduced.

Description

technical field [0001] The invention relates to the technical field of security video monitoring, in particular to a dome camera pan-tilt control system. Background technique [0002] Dome camera, the full name is dome camera, is the representative of the development of modern TV monitoring. It integrates multi-functions such as color integrated camera, pan / tilt, decoder, and protective cover. It is easy to install and use, but powerful in function. It is widely used in the monitoring of open areas and can be used in different occasions. [0003] Among them, the pan / tilt is the support device for the fixed ball machine. Under the action of the control signal, the camera on the PTZ can not only automatically scan the monitoring area, but also track the monitoring object under the control of the personnel on duty in the monitoring center. Among them, PTZ (abbreviation of Pan / Tilt / Zoom) pan / tilt can control the magnification and zoom of the pan / tilt moving up, down, left, and...

AI Technical Summary

Problems solved by technology

[0004] At present, to realize the PTZ pan / tilt control of the analog dome camera, most of them adopt the method of adding an additional 485 twisted pair to transmit the control signal while the video signal line transmits the video signal shot by the dome machine, which increases the It increases the cost of wire and wiring personnel, and also increases the complexity of the security wiring space
