Description

Big data analysis system

Technical field

The present invention relates to big data field, more particularly to a kind of big data analysis system.

Background technology

The drawbacks of inherent be present in the artificial anti-mode taken on the sly：First, if auditorium area is larger, need to arrange for a lot Staff carries out field monitor, it means that needs substantial amounts of cost of labor；Secondly, the mode of staff's naked eyes scanning is imitated Rate is low, and the mode of direct surveillance easily occurs to let off the person of taking on the sly of some corner locations because of burnout；Finally, seeing Many modes for nearby setting staff bring discomfort to the spectators of normal viewing performance, have impact on them and appreciate the heart of performance Feelings.

As can be seen here, the artificial anti-mode taken on the sly has inborn deficiency, in order to overcome above-mentioned drawback, reduces and prevents what is taken on the sly Operation cost, the anti-operating efficiency taken on the sly is improved, operator always searches for the anti-mode taken on the sly of electronics and carries out on-site supervision, electricity Anti- take on the sly of son has two kinds of developing direction, and a kind of made an issue of on the mobile terminal held in spectators, when mobile terminal is shot certainly Dynamic detection is taken on the sly behavior, but this mode may be because that the person of taking on the sly is avoided to the selection of mobile terminal, another kind be The scene of taking on the sly disposes electronic jamming device, and this mode can avoid evading for the person of taking on the sly.

The existing anti-electronic jamming device taken on the sly is that a kind of infrared facility is placed in the back side of curtain or stage, Infrared facility sends the sightless infrared ray of human eye, infrared if the person of taking on the sly is moving terminal or video camera shooting Line will disturb the video camera imaging of the person of taking on the sly, the image or lower picture quality for causing the person of taking on the sly to obtain, can not commercially sell Sell and propagated on network, so as to effectively safeguard copyright interest.

But this mode needs to launch infrared ray always, and the transmitting of infrared ray is large-scale, it is necessary to from each Infrared ray is all launched in position, and cost is higher and poor feasibility.Therefore the anti-equipment of taking on the sly of the electronics at scene also needs to find others Break through direction.

Therefore, the present invention proposes a kind of anti-electronic equipment taken on the sly in new scene, can be by audience seat The behavioral value of spectators and determine to whether there is in audience seat the person of taking on the sly by the parameter extraction to site environment, and The position where the person of taking on the sly can be positioned in time, in order to take corresponding orientation warning measure.
