Problems solved by technology

In addition, if the signal is transmitted through the general public communication network, it is often limited by the bandwidth, so that the quality of the image must be sacrificed, which reduces the quality of the monitoring system
It is worth noting that only point-to-point optical fiber signal transmission will also increase the cost of optical fiber line setup

Embodiment Construction

[0034] The optical fiber signal mixer of the present invention and the optical fiber audio-visual monitoring system using the optical fiber signal mixer can effectively increase the distance and quality of monitoring, and can increase the number of audio-visual signals transmitted by the optical fiber, and can be controlled by remote or near The end directly controls the fiber optic signal mixer, so that the monitoring personnel can easily adjust the equipment from the remote end. The spirit of the present invention will be described in detail below in conjunction with the accompanying drawings. After those skilled in the art understand the preferred embodiments of the present invention, they can be changed and modified by the technology disclosed in the present invention, but it does not depart from the spirit of the present invention. with range.

[0035] see figure 1 , which is a schematic diagram of a preferred embodiment of the optical fiber audio-visual monitoring syste...

Abstract

The invention relates to an optical fiber signal mixer. The optical fiber signal mixer comprises a first optical signal transceiver, at least one signal input port, a controller and a second optical signal transceiver. The first optical signal transceiver receives an original optical image signal; the controller converts an image signal from the signal input port into an additional cable TV imagesignal and mixes the additional cable TV image signal with an original cable TV image signal; and the second optical signal transceiver converts the mixed cable TV image signal into a mixed optical image signal so as to carry out the remote-end monitoring. In addition, the invention also discloses an optical fiber video monitoring system using the optical fiber signal mixer.

Description

technical field [0001] The present invention relates to an optical fiber signal mixer, in particular to an optical fiber signal mixer of a closed high-bandwidth optical fiber audio-visual monitoring system. Background technique [0002] In recent years, as public security incidents have received more and more attention in our daily life, such as: personal safety issues, theft or traffic accidents, in order to reduce the damage caused by such public security incidents to society, image Basic monitoring systems are widely used to monitor various abnormal event conditions in real time. [0003] The monitoring system can effectively prevent the occurrence of social problems through the archiving and monitoring of audio-visual materials, and at the same time avoid the problem that both parties hold their own opinions and cause the truth to be difficult to distinguish. Therefore, the real-time monitoring function and identification accuracy of the monitoring system become very im...
