Remote video monitoring device

Abstract

The invention discloses a remote video monitoring device which effectively solves the problem that in the prior art, due to the fact that the electromagnetic environment is complex, the phenomena of 'crossways', 'ripples' or a plurality of disordered flying spots and the like existing in monitoring video images of an elevator car cannot be completely eliminated. The remote video monitoring device comprises a signal collecting module, a signal transmission module and a monitoring center, wherein a signal push-pull circuit and a signal compensation circuit are arranged between the signal transmission module and the monitoring center, the signal push-pull circuit receives monitoring signals transmitted by the signal transmission module through a push-pull device, frequency results are obtained after the monitoring signals pass through a frequency selector, the frequency results and the monitoring signals are transmitted to the signal compensation circuit, the signal compensation circuit enables the frequency result to pass through the converter and then conduct the compensator, and the compensator transmits a monitoring signal to the monitoring center, so that the situation that watching of a monitoring video of the elevator car by a worker is affected is avoided.

Description

Technical field [0001] The present invention relates to the field of video surveillance, particularly a remote video surveillance device. Background technique [0002] In recent years, with the development of the Internet, and the construction needs of smart cities, security, finance, road traffic, electricity and other monitoring projects, remote monitoring video technology that uses cameras has become an indispensable part of people's work. However, in the actual use of the office building, it was found that the signal acquisition module transmitted by the signal transmission module such as the monitoring signal of the camera collected and displayed after the monitoring center, found that the displayed image was mixed with messy "crosswind", "ripple" or A messy fly point, thorns, linear interference, occurrence of image blur, distortion, jitter, roll, etc., such as figure 1 As shown, in particular, the monitoring video responsible for collecting the camera transmission of the e...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a remote video monitoring device, which effectively solves the problem of "horizontal road" and "cross track" in the existing technology that cannot be completely eliminated in the monitoring video image of the elevator car due to the complex electromagnetic environment in the prior art. Phenomena such as "ripples" or bursts of random flying spots
