On April 17, 2018, the Guangdong Press, Publication, Radio, Film and Television Bureau hosted the technical achievement appraisal meeting of the 1600m2 studio lighting and hanging system project of Guangdong Radio and TV Station jointly declared by Guangdong Radio and TV Station and Guangzhou Squande Lighting Co., Ltd. in Guangzhou. The meeting was chaired by Zhuang Wei, Director of the Science and Technology Department of the Guangdong Press, Publication, Radio, Film and Television Bureau. The director of the appraisal committee was Mr. Du Baichuan, deputy director of the Science and Technology Commission of the State Administration of Radio and Television. The experts of the appraisal committee were Mr. Wang Jingchi from the Central Radio and Television Station and doctoral students from Tianjin University of Technology. Tutor Niu Pingjuan, Mr. Zhong Guohong of Guangzhou Radio and TV Station and relevant leaders of Guangdong Press, Publication, Radio and Television Bureau.
The appraisal committee listened to the project's work report, technical report, inspection report, new report, user report, and project implementation and inspected the relevant data, scene change effects, and three-dimensional integrated high-precision lighting of the large-scale studio. The actual operation of the hanging system.
After argumentation and testing, the expert group agreed that:
The hanging system consists of hanging basic structure, control system and hanging equipment. The system can perform three-dimensional control and cover the entire studio without blind spots. It adopts full digital closed-loop multi-axis control, which can control multiple hanging equipment and perform multiple For different movements, with the help of incremental encoders and other technologies, the vertical positioning accuracy reaches ±2mm. A total of 112 three-dimensional hanging units, 29 horizontal hanging units, and 40 electric hoists are equipped. It can meet the needs of many different types of program production, realize the beauty of the dance in the entire studio, multi-dimensional lighting effects, and no blind spot coverage. It can meet the needs of many different types of program production.
The system adopts a number of key technologies such as three-dimensional integrated boom, automatic inline rope technology, self-lifting technology, anti-loosening rope technology and anti-swing design, which simplifies the technological structure of the light layer and exceeds the level of static lighting and scenery. In the process of the program, it can meet the needs of the program to produce dynamic effects and enrich the program production methods.
The project system has the functions of upper and lower logical limit, upper and lower limit protection, horizontal walking anti-collision limit protection, anti-crushing limit protection, loose rope protection, overload protection, overspeed protection, emergency cut-off switch and automatic stop of light pole, etc. Increased safety and reliability.
The system adopts all-digital closed-loop control system, adopts dynamic backup, programmable control, frequency conversion control, position detection and other technologies to centrally and synchronously control all equipment, and can realize grouping movement, real-time scene call transformation, high-precision lighting scheme call And other functions.
The system has excellent construction technology and concealed works in this project. The line troughs and line pipes are neatly arranged and clearly marked; the connection positions of all line troughs and line pipe transfer boxes are bridged with special grounding cables to ensure safe and reliable grounding protection; The system uses a large amount of wire and is heavy. The corners and key overlapping parts are fixed with ribs, which is beautiful and convenient for heat dissipation.
The project system has been running since September 2016, and so far has carried out "I am a live singer", "National Music Festival", "Pearl Channel Channel Promotion Evening", "Nanpai Documentary Awarding Evening", "2017 Spring Festival Gala" , “Guangdong and Hong Kong Popular Songs Ranking Evening Party”, “Maiwang Contend for Hegemony” and more than 100 large-scale programs, with significant social and economic benefits.
In summary, experts of the appraisal committee believe that the project has stable system performance, strong technicality, excellent construction technology and innovation, reaching the international leading level, and has strong market promotion value.
