I. Overview
With the continuous development of social economy and technology, intelligent lighting and multimedia application solutions for museums and other large venues are increasingly valued by owners and designers.
The multimedia sound and light synchronous demonstration technology is a successful combination of intelligent lighting technology, multimedia presentation technology, dance art and exhibition art. The accuracy, reliability and ease of operation of networked and intelligent synchronization are the highlights of the museum's natural landscape demonstration control system.
Second, the system network composition
The museum demonstration system uses the SHOW-CONTROL multimedia sound and photoelectric synchronous performance system in the HDL-BUS system. The core part is SHOW-CONTROL multimedia linkage control software, which is a multimedia centralized control software integrating lighting control, audio control, video control, performance control, etc. It provides a third-party control interface to facilitate system expansion.
SHOW-CONTROL multimedia sound and photoelectric synchronous performance system is mainly composed of multimedia synchronous performance server, basic lighting control module, stage effect light controller, multi-function control panel and remote infrared remote control.
The projector for playing video files is connected to the multimedia synchronous performance server through the video data line; the stage effect lamps (computer lights, hoods, LED lights, etc.) and the DMX performance controller are connected by an international standard DMX512 signal, and then The TCP/IP network signal output port of the DMX control module itself is connected to the network switch by Ethernet; the multi-function control panel and the basic lighting module are connected by RS485 bus, and converted into TIP through the HDL-BUS bus switch. The /IP network signal is connected to the network switch.
Third, the system main hardware
HDL-BUS system hardware used
12-channel 10A intelligent dimmer: Dimming control of high-power PAR lamps and spotlights in the exhibition area, combined with natural changes in the scene to achieve changes in the illumination of animal specimens.
6-channel fluorescent dimming module: dimming the fluorescent lamps in the background painting in the exhibition area to create natural effects such as sunrise, sunset and dusk.
DMX control module: Scene control of effect lights such as computer moving head lights and color changing lights used in the exhibition area.
Multi-function programmable control panel: used to store lighting scenes and performance programs.
SHOW-CONTROL multimedia linkage control software: installed in the lighting control server, it can control the audio and video system according to user needs. At the same time, the HDL-BUS system, the HDL-NET system, and the systems or devices provided by third parties can be controlled through the network. Through the combination of art and technology, a series of user needs or satisfactory effects are achieved, so as to achieve the purpose of simultaneous sound and light performance, giving people a refreshing sense of body and mind.
Infrared remote control: used to remotely launch performance programs and lighting scenes.
6-channel intelligent switch module: switch control of conventional switch lighting fixtures, strobe lights and other lamps in the exhibition area.
Fourth, the system settings
The functional requirements of modern museums and multi-purpose venues are increasing, and new requirements are placed on the control systems and display technologies used in the venues. In the means of display, it is necessary to make full use of modern art techniques and advanced multimedia control techniques. In addition to the traditional display, the specimens are brought closer to the audience in an interactive manner, so that the natural objects and people are perfectly integrated.
Modern museums and multi-purpose exhibition spaces use a wide range of lamps. Its functions and control methods are different.
Track dimmable downlight: used as backlight and face light for animal specimens, PAR light is equipped with a color changer, used as a backlight for animal specimens. The system hardware uses the HDL-MD1210 intelligent dimming controller for dimming control.
Fluorescent lamp (with dimmable electronic ballast): used as a change in the background painting of the exhibition area, such as blue sky and sunset. The system hardware uses the HDL-MRDA06 digital dimming interface module for dimming control.
Cloud lights, rain lights, strobe lights, water lights: used as running clouds, projected on the surface of the lake, water, lightning and electric flash. The system hardware is controlled by the HDL-MR 0610 intelligent switch module.
Multimedia Acousto-Optical Control Server: used to load audio, video, and SHOW-CONTROL multimedia linkage control software.
The above equipments are installed in the central control room respectively. The control panel can be installed in the exhibition hall with the standard 86-box wall installation. The HDL-BUS building intelligent control product hardware is intelligently controlled by an HDL-BUS bus. The wiring installation is very Flexible, it can be co-located with strong power, and the multimedia sound and light control server of the central control room is connected with system hardware by Ethernet signal.
Linkage with other systems: The system can receive the dry node signals from other systems or staff through system components, and realize the linkage of fire protection system, security system, sound system and conference system, so that the controlled lights or equipment can be changed in time.
V. System superiority
1. Simple wiring and easy maintenance.
The lighting circuit is simple in design, easy to install, and easy to operate and maintain. According to the changes of the environment and user needs, only the software modification settings or a small number of line transformations can realize the change and function expansion of the lighting layout distributed control system.
2, colorful artistic effects.
A variety of lighting effects to achieve a variety of lighting control methods, can make the animal specimens in the museum have a variety of artistic effects, adding a lot of color to the animal specimens. The light of different colors gives the museum vitality, making the whole scene more vivid and artistic, giving a rich visual effect and beauty. According to different time, different use, different effects, using the corresponding preset scenes for control, can achieve rich artistic effects.
3. Easy management and maintenance.
HDL building intelligent lighting control system is mainly controlled by modular automatic control, supplemented by manual control. The parameters of lighting preset scene are stored digitally in the control panel. The setting and replacement of these information is very convenient. Lighting management and equipment maintenance in the museum has become easier. At the same time, the entire demo program is also stored on the panel. When a visitor enters, the interpreter will simply turn off all the unwanted lighting scenes and enter a sound and photoelectric synchronized performance program with a single click.
4. Extend the life of the light source.
Extending the life of the light source not only saves a lot of money, but also greatly reduces the workload of replacing the luminaire, reduces the operating cost of the lighting system, and makes management and maintenance simple. Whether it is a thermal radiation source or a gas discharge source, fluctuations in the grid voltage are a major cause of damage to the source. Therefore, effectively suppressing fluctuations in the grid voltage can extend the life of the light source.
5. Good energy saving effect.
HDL building intelligent lighting control system uses various "pre-set" control methods and control components to accurately set and manage the illuminance of different environments at different times to achieve energy saving. This method of automatically adjusting the illuminance only lights up or points to the required brightness when necessary, and uses the minimum energy to ensure the required illuminance level. The power saving effect is very obvious, generally up to 30%. In addition, the intelligent lighting control system performs dimming control on the fluorescent lamps in the hall. Since the fluorescent lamp adopts the dimmable electronic ballast with active filtering technology, the harmonic content is reduced, the power factor is improved, and the low voltage is reduced. Power loss.
