Embodiment
The embodiment of the arenas suspension rod safety control platform of the present invention is described in detail below with reference to accompanying drawings.
Stage or theater development mainly have following characteristics at present：Plant equipment has high-tech content.In plant equipment
Largely use high-tech achievement, such as computer technology, Numeric Control Technology, hydraulic technique, sensor feedback technology, fieldbus skill
Art, DCS technologies etc..
In the design of stage or theater machinery, manufacture, detection, examination, maintenance etc., Germany, Austria, the machine of Japan
Tool is in addition to the universal standard for performing national machinery industry, the also application specific standard of stage or theater machinery, professional stage or theater
Some mechanical equipment set and formed basic model, set special stage or theater machinery to set always according to the specific story of a play or opera sometimes
Standby be specific directory service, and the trend that stage or the oriented maximization of theater plant equipment develop.
Public staging platform is the process that stage or theater can most reflect a country present age development of civilization, one
Staging platform is a collection aesthetics, architecture, architectural acoustics, electroacoustics, electronics and electronic technology, computer networking technology, electricity
Depending on that technology, stage machinery, light of stage, monitoring, Modern Decorative, theatrical art etc. be multidisciplinary, multiple solutions are combined closely is grand
Science and art systems engineering.
The development of modern public staging platform is inseparable with modern science and technology, and he produces with the progress of science and technology
Raw change with rapid changepl. never-ending changes and improvements, he is that stage or theater art create more development spaces in limited stage or theater,
The possibility of more more options is provided to director, dance ＆ art personnel.For this mechanical industry of staging platform, the design of basic machine,
Manufacture, processing, installation difference not too many compared with other machinery industries, he is also in compliance with the general of Development of Machine Industry
