Problems solved by technology

[0002] At present, in the equipment used in the remote command system, it is very difficult to expand the number of the remote end of the system, especially in the case of multiple users, and it is impossible to monitor and return the remote end; The end loudspeaker cannot be used selectively, such as using a certain remote or several remote
In addition, the way of wired connection limits the distance of the far end. If optical fiber transmission is used, it will be difficult to match with the optical fiber transmission system, and it is difficult to carry out long-distance transmission.

Embodiment Construction

[0019] The technical solution will be described in detail below with examples.

[0020] The remote command system of the present invention is a system specially designed for remote command. The system includes a central terminal and several remote audio and video equipment and optical transmission equipment. The optical transmission equipment includes a central terminal optical terminal 2, an optical fiber 3 and several remote optical terminal 4. . The audio and video equipment at the central end has a multi-signal input and output processing unit for gating the audio and video equipment at the far end; the audio and video signals of the audio and video equipment at the central end are transmitted to the audio at the far end through optical transmission equipment The audio and video equipment is used for commanding, and the audio and video signals of the remote audio and video equipment are transmitted back to the central audio and video equipment through the optical transmiss...

Abstract

The invention relates to a remote commanding system, including: broadcast hosts, microphones and monitors at the center-side; and amplifiers, speakers, microphones, image acquisition devices and detectors at remote end. The broadcast host includes an MCU center processor, a multi-signal input and output processing unit, a channel controller, an input interface, a channel interface and/or a USB interface. The amplifier includes an interface recognizing and squelching unit, and a low-frequency suppression unit below 100Hz. The optical transmitter and receiver includes a digital signal processor, an interface identifier, a D/A converter and an A/D converter, a pre-amplifier, an optical drive and optical interfaces. The inventive remote commanding system has advantages of: easy expansion of the number of the remote terminals which are composed by optical fiber transmission and flexible matching outdoor type amplifiers; capability of optionally selecting the remote region and monitoring and returning back to the remote; reliable signal transmission; easy operation; and dependable guarantee to the remote command.

Description

technical field [0001] The invention relates to a control device, in particular to a remote command system. Background technique [0002] At present, in the equipment used in the remote command system, it is very difficult to expand the number of the remote end of the system, especially in the case of multiple users, and it is impossible to monitor and return the remote end; The end loudspeaker cannot be used selectively, such as using a certain far end or several far ends. In addition, the way of wired connection limits the distance of the far end. If optical fiber transmission is used, it will be difficult to match with the optical fiber transmission system, and it is difficult to carry out long-distance transmission. In order to solve the above problems, it is urgent to innovate the transmission technology and equipment used in the remote command system. Contents of the invention [0003] The purpose of the present invention is to provide a remote command system that ...
