Stage and stand related security monitoring system

Abstract

The invention provides a stage and stand related security surveillance system which comprises a control unit, a first step lifting control unit and a second step lifting control unit, wherein the first step lifting control unit is used for controlling a first step; the second step lifting control unit is used for controlling a second step; a pressure sensing unit is used for sending a descend starting signal to the control unit when the sensed pressure rises from a value lower than a first preset pressure value to a value higher than a second preset pressure value; and when the control unit receives a descend starting signal sent by a light receiving unit, the light receiving unit sends descend index signals to the first step lifting control unit and the second step lifting control unit, so that the first step lifting control unit controls to cause the first step to enter into a falling position, and the second step lifting control unit controls to cause the second step to enter into the falling position.

Description

technical field [0001] The present invention relates to the field of stage design, and more specifically, the present invention relates to a security monitoring system associated with a stage and stands. Background technique [0002] The stage is the space provided for actors to perform in the theater, which can make the audience's attention focus on the actor's performance and obtain the ideal viewing effect. The stage usually consists of one or more platforms, some of which can be raised and lowered. The types of stage are proscenium stage, extension stage, ring stage and revolving stage. [0003] However, with the rich and colorful people's cultural life, there are more and more stage performances; what follows is that stage safety incidents frequently occur during the organization of performances. Therefore, the issue of stage safety has become an issue of increasing concern. [0004] For stage safety protection, some measures such as adding guardrails have been propo...

But, the measures of these prior art can not prevent the generation of safety accident well

[0005] Among them, one of the stage safety accidents is that people in the stands ran to the stage for no reason, thereby disturbing the host of the host or the performance of the actors.
