Weak current College】 【large lighting control system design and composition.

<br> In the design of the lighting control system of the programme should be actively modern television lighting construction requirements, taking into account system reliability, advanced design, rationality, and economics, the configuration is a set of "State <br> International advanced ., Chinese first-class ", control, flexibility, ease of operation, fully modernized, intelligent, networked lighting control system. Below, you will find details of lighting control system design and structure of function <br> 10%. <br> First ., the lighting control system functionality design <br> <br> As early as the mid-1990s, as the main development of ACN Protocol, a member of ShowNET lighting company networked lighting system signal interface for all devices, have been proud to fight " .ACNReady <br> "(ACN ready) bearing in mind; from 1993, San Francisco Opera, StrandShowNET networked lighting system in the world, especially Europe and the Lyric Theatre and TV Studio, have normal continuous working <br> Nearly 10 years. < .br> <br> "ShowNET" networked digital dimming system in Chinese TV station application, focused on behalf of the Chinese television lighting construction to the modernization and internationalization and the digitization, network towards the direction. Technically, <br> Truly the full implementation .of resource sharing, effective protection of the individual Studio light control DMX signal output reliability and consistency, greatly facilitates the creation and performances of light on stage lighting <br> Direct, monitor and remote control, with unparalleled value and broad application prospects. <br .> <br> 1. network control linkage design <br> <br> 1) linkage range: the studio lighting network control - television network interactive <br> <br> Television stations in several studios, each site's primary, Deputy (or backup .) lamp control console through a network of distributor and network nodes, and dimming Silicon Cabinet, formed the autonomous independent digital lighting control network <br> This complex, control of the stage and Auditorium lighting, the signal completely track the backup and control information sharing .through network communication interface, points set covering, control, remote control and monitoring. In addition, the entire electricity <br> TV announcements on the network Burean lighting network, through the unification of the TCP / IP protocol using fiber one, program management personnel .to the Central engine room monitoring the functioning of the Studio lights; the terrace Studio lighting <br> Room can also be sharing of resources, each can learn from each other, mutual calls, mutual monitoring, each backup, give full play to the television .station the studios control resources comprehensive utilization. <br> <br> 2) operation function <br> <br> A. communication function: network technologies meet the DPS and CISCO, and other digital communication technology development prospects and requirements to facilitate the implementation .of the remote control, remote diagnosis and factory technical support; <br> <br> B. monitoring capabilities: lighting operator can lighting control room or auditorium, directly by adjustable desk display, informed about the lighting system instant information and status of work on .all sites in a timely manner or the back lights <br> Optical surveillance, intervention or correction; you can also use the laptop plugged into any Ethernet interface for the whole network including SLD96 function monitoring or obtain lighting information report. <br> <br .> C. design features: a light 'variable lighting design "field" to "desktop design to facilitate the implementation of the" technical means can be remote or offline edit, shorten the loading station and light against the light time, improve work efficiency < .br>. .<br> <br> D. sharing features: wireless remote control unit can be the scene of each Studio room control system facilitated, flexible operation instructions. To popular iPag-Pocket Personal Assistant (PocketPC) <br> Strand remote control software. This .combination to wireless network (802.11b) and the working point (Accesspoint) attached to each Studio room "ShowNET" network. Remote controller can handle all the control console and backup machines <br> Control circuit, recording function and the scene was broadcast, .to stage lighting / light brought a great convenience, of course, with output DMX address to the features on the control loops. Use native network browser software <br> Easily through the network on all "ShowNET" SN110 outlets. <br> <br .> E. backup function: network dimming between mutual learning, mutual backup, backup table to the schema of the network and is connected to the primary and secondary control console and use the whole track backup mode on the console for learning, that is, two .tone <br> Parallel processing of optical bench, lighting engineer at any stage button, another you'll learn; when standby control console in any computer failure, another will automatically and immediately turn into real-time follow up output; in the event of .a network <br> Failure, the backup application is automatically put into the network. In this way can give full play to the role, the device resource and ensures that performance recording or Conference lighting control foolproof; <br> <br> F. .compatibility features: network systems firm, programming, hardware structure does not change, you can use a software upgrade for the system; when ACN agreement when global adoption, simply remove the SN110 node <br> Out to implementation. As a result of ShowNET systems .has been using the TCP / IP protocol for network communications, for the vast majority of today's international software suppliers are used (such as Microsoft's Windows O / S-led), <br> STRANDShowNET system can be used with other TCP / IP shared its .pipeline to reduce project costs significantly increased system compatibility and forward-looking, as well as television management towards information freeways, laying a solid foundation <br> Foundation. <br> <br> 2, network conflict prevention programme <br> <br> .1) network conflicts arise <br> <br> A wide open network provides us with unlimited resources shared space and versatility of charm, but also inevitably conflict with the scope. We at design time to fully considerHouseholds <br> Use any that might arise .could result in system failure and all, to provide reasonable and effective prevention programmes. The so-called light control network conflicts arise because of network ports open for the whole of the port address <br> Configuration conflicts. This mainly includes two aspects: < .br> <br> (1) multiple conflicts in network Burean: control-end refers to the control of lighting system console, remote control, and other control devices. Television mainly by the Studio, for network control, each <br> Studio is .an independent and open. When we use the network system completely open, the operation may have multiple console control signals of the same set of lights (such as a number of studios and 2 Studio 4 <br> Console at the same time control a number .of studios of dimming Cabinet), because the control signal of staggered control, in the absence of a comprehensive prevention programmes, which will inevitably result in the confusion of lighting control; <br> <br> (2) a single Studio in conflict: .the independent a Studio, the same situation is possible: the lighting network system in each network node can be set to the lighting control <br> System input port, therefore, arise in the same Studio, multiple unknown console at the same time control a .set of lighting control signals of the phenomenon is possible. <br> <br> 2) network priority determine the programme <br> <br> Network performance is good or bad, the key factor is how to prevent network conflicts. StrandShowNET system has .a comprehensive programme of prevention of conflicts: <br> <br> ① each device shall have only one IP address, Access automatically after the device has an address, you can also go to the network management software ShowNETConfiguration set it up. <br> .<br> ② each device can set the priority level of the control, a total of 255 levels. <br> <br> ③ each network console has a separate ID number, and the DMX node ID will be the default setting is 0. .Each port in the DMX node number 1-4. <br> <br> ④ in order to be able to better compatibility control work lamp / field lights, environmental lighting control system, in particular to its control system (skin tight Asian) set .up side-by-side handler. <br> <br> ⑤ According to the above set of flags to form a complete set of the judgment. <br> <br> 3, dimming conflict prevention measures <br> <br> 1 .) dimming control multifunctional set <br> <br> A Strand500 or 300 system consists of a 500 and 300 Control Panel and the associated processors that can run in StrandShowNET network. The network includes other systems, for example: other <br> A 500 .system or a 300 light control systems. All of these systems can share Studio currently using dimming circuit, and each system can be independent of the control. As long as the dimming circuit <br> Controlled circuit after HTP, LTP, MERGE set, you .can be more than one system. <br> <br> HTP (HighTakePrecedence): several signal source to the brightness level of high-priority output; <br> <br> LTP (LatestTakePrecedence): several signal source to the brightness level to .change the value of the final output. <br> <br> Merge: several signal source for graded assignments after merging to output. <br> <br> The above pattern settings, a single managed element can be ordered from one of these conventions ., which at the same time output accept several control element of the control. <br> <br> 2) dimming platform identity <br> <br> Strand500 or 300 system software guarantees that in more than one system of network application without dimming circuit .of control of the conflict. Because the system start, we have set up various dimming platform IP address <br> Positioning their different priorities, specifically its console, console or backup, and remote control machine, only when the backup automatic confirmation of the " .host "status console fails automatically on-line. Of course, in large <br> Performance are often available through the menu selection Division processing, such as the host for the traditional lamp control, a control console for the color picker control, etc. ., you can set function to create a second or even third or fourth control input to the system as <br> Console role on a bifurcation. In remote control mode, each console has its own independent input commands and display, and the control circuit data .for "Partitioned" (segmentation) and recorded. <br> This feature allows a console independent record control circuit of the primary CUE farm, while at the same time, other lighting engineers can utilize their loop segmentation and performs in the same CUE farm. .With the display and all alone <br> A list of the loop, the loop for each console is the entire system can be divided by any part, in order to meet the program requirements of the performances. <br> <br> 4, .the system uses the life design <br> <br> Lighting system life cycle need to be considered from two aspects: <br> <br> First, you need to consider all of the system itself is composed of equipment components, component failure rate .. <br> <br> Electronic equipment damage often six reasons: <br> <br> 1) wear: frequency of use, contact parts wear consumption; <br> <br> 2) insulation material cracking: some cracking deformation; < .br> <br> 3) dust: circuit board after powerup dust can cause fever, abnormal temperature will cause the rapid aging of parts; <br> <br> 4) contact oxidation: causing bad, contact resistance increase resulting in fever, the .formation of oxide layers, due to open slowly <br> <br> Road phenomenon; <br> <br> 5) vibration: weak vibration can cause Terminal, connector contact surface displacement, thereby causing poor contact; <br> <br> .6) after years of aging: electronic components particularlyDC power supply and its associated circuit board components on the relative service life as compared with other parts of the electronic circuit is short, the need regular maintenance and, if necessary, to be replaced. <br .> <br> Lighting system and feature software, version from early 1.0 after 1.1 (ah), 1.2 (aj) to present the latest 2.6d, product features and techniques constantly update and move forward, not backward. <br> <br> .As previously described, the networking programme to fiber-optic cable and the integration of the data distribution Cabinet link into the network, the future line extension and needs, so we put the fiber-optic cable used condition is defined as: <br> < .br> The first pair of light dimming control signals and the second alternate <br> <br> Third on network information fourth on standby <br> <br> To facilitate the increase of managed at any time. <br> <br> In .addition, this system at the beginning of the design to control devices are designed for daily use, and is expected to be powered until the required maintenance work when the power-off check. <br> <br> Secondly, the need to consider the .equipment upgrade and spare parts supply period. <br> <br> Second, the lighting control system network constitutes <br> <br> 1. network infrastructure <br> <br> Television regardless of rank, size, Studio, its lighting network .is available to the television station backbone network and studio lighting control system network made up of two parts. Backbone network is responsible for various studios <br> And technology, production and management of data transfer between departments, system connection sharing. The main use of .advanced, stable, high-speed single-mode fiber Gigabit Ethernet technology. TV system network Burean lighting control <br> System, Studio audio control system, Studio video control system, such as Studio computer systems resource sharing becomes a scientific and rational and convenient .. <br> <br> Television network system design including backbone network design and network design for a single system. <br> <br> 1) backbone fiber network: backbone network is the television of various physical point such as Studio, technical Office ., warehouse, Program Director, etc. contact network of control. Backbone network because the line is long, the transmission of information <br> Many classic fast Ethernet network 100BASE-T oneself does not meet the modern needs of users, representing up to this .responsibility is based on single-mode fiber Gigabit Ethernet network system. <br> <br> Following is some kind of network media transmission distance of comparison: <br> <br> Various wire signal transmission distance comparison table <br> <br> .Tape standard name Media medium Distance (max) transmission distance <br> <br> 1000Base-SX <br> <br> Wavelength 850nm62.5 micron multimode fiber 1KM <br> <br> 50 micron multimode fiber 2KM <br> <br .> 1000Base-LX <br> <br> Wavelength 1300nm62.5 micron multimode fiber 1.5KM <br> <br> 50 micron multimode fiber 3KM <br> <br> Single-mode fiber 5KM <br> <br> 150M 1000Base- .CX coaxial cable <br> <br> 100Base-T4 on 5 twisted-pair 100M <br> <br> DMX5125 core signal line 330 m <br> <br> At present, many television network system design concept is fairly complete, each .have their own computer network system, system of trunk connections between considering transmission distance and signal quality and system in the future <br> Expansion through the Media Converter converts the signal source for transmission of optical signals. As a result based on single-mode fiber .Gigabit Ethernet technology, the expansion of the overall network and the connection is relatively simple. Trunk light <br> Fiber network to be fully compatible with Studio network system, thus saving both investment and make rational use of resources, so that the whole system features .. As long as the cable signals for direct access television network <br> Complex optical fiber transceiver, you can use Internet resources within a resource sharing computer network. Lighting systems, audio systems, video systems, the computer system is used for file sharing; .at the same time, by calculating the <br> Computer network and Internet connections to the INTERNET, convenient for system on the Internet simple realization system upgrades and maintenance of Remote Diagnostics. <br> <br> 2) lighting control network system (Studio .Ethernet / DMX lighting network) <br> <br> Lighting control network system refers to the Studio of networked lighting control system. Using Ethernet / DMX network control, the entire control system strictly follow the TCP / IP communications protocol and USITTDMX512 Protocol <br .> (1990). Lighting control system into a star distribution, the Studio signal to focus on their respective thyristor unit, through a hub distribution Ethernet node, data transmission medium used six class Ethernet signal cable; DMX letter <br> Letter from network provides .numerous SN110 network node. Each SN110 has a LCD display to provide information, instruction and two DMX interface. Each interface can take advantage of networking with software or browser to be set. This <br> Function allows to set processes from each of the Studio's .central computer or any wireless scene done on the remote control. All the work power SN110 directly from the network cable from the network (International latest standard IEEE802.3af) <br>. .All mobile-network unit can directly use the plug-in and the walls of the network interface is connected and powered on. By StrandSN1XXNODE (network node) for Ethernet control signal and DMX signal of mutual <br> Conversion, and a reasonable distribution of .the DMX signal at the Studio. Lighting network configuration with a dedicated network configuration software, and can provide various information in the network node unified configuration, amend. Network with Ethernet control <br>, DMX control, wireless remote control, cable remote control, .and can add admission to light control system as well as environmental lighting control system. <br>> <br> In this scenario the use of technology, to introduce a lighting company, the world's developed and continuously improved, now is the world leader of .StrandShowNET technologies, including the latest wireless network <br> System, the latest work in the power of the network wire River walk, etc. to provide the flexibility of the control system. It will light control system fully into a network system, and seamless .integration, focus on lighting control <br> Technology systems integration and expansion, makes the light network control more convenient. Application ShowNETTCP / IP protocols, and software, to the lighting control brings the latest technological innovations. <br> <br> Studio lights .digital control system devices can be used by the system of uniform control, no signal compatibility issues. Apply powerful StrandShowNETConfiguration network configuration <br> Editing software through the user-friendly interface allows any placement information system implementation, but also from any specific zone update SN1XXNode ., avoids to run from one network to another network to update the system cumbersome <br>. .The software can be set to assigned to assign all Ethernet location information, IP, gateway, multicast group and branch network information to each network. It can be said is on traditional StrandShowNET DMX512 of <br> Significant technological innovations, is a lighting control system .for a qualitative leap, which thoroughly solve thousands of loop big Studio (or multi-function TV Theatre) circuit distribution and more dimming and control the same set of dimming Cabinet and NC <br> Equipment, and a series of single application could not be .implemented by DMX512 network of technology challenges. <br> <br> In the lighting control system of the terminal equipment we picked a StrandSN102 (with network video terminal for network nodes), the device can set the network is connected to the lighting control system .with any information in the <br> (Including the running of the lighting console work interface) for real-time monitoring, allows central control room system maintenance personnel can timely understanding of control systems and equipment for all signals, including dimming, <br> .Cabinet of signals, timely processing of lighting equipment for technical breakdowns, the rational use of resources for the device, make the equipment utilization. In addition, the device data transfer protocol is the standard TCP / IP Protocol, it may <br> To place .in any network control line offices, other Studio etc as long as the backbone network of the region. In addition, use the remote controller, such as Remotehandheld so that lighting control more comprehensive, more <br> Plus system and easier. <br> .<br> In order to protect the system reliability and stability, we each central control room use uninterruptible power supply UPS, recommend the use of United States APC UPS products. The uninterruptible power supply (UPS) is online <br> Type (ON- .LINE) system, it can provide for load frequency, voltage, uninterrupted high-quality pure sinewave AC. The system can effectively overcome supply power directly from the outside power grid caused frequent power quality issues <br>, If the voltage is too high, .too low, power surge or instant sharp wave, power line noise interference, power supply interruptions or outages, etc., in order to ensure the normal operation of equipment, prevent computer and data processing Department <br> Marketing information missing, UPS uninterruptible power .supply is especially designed for a variety of micro-computer network, small computer, workstation, and precision electronic equipment design, run extremely reliable, but also can increase the battery back-up power supply extension <br> Time to meet on cut-down .for long times by users' special needs. <br> <br> 2, network wiring <br> <br> In this scenario, network wiring, wiring and connection box of the process are required to do very detailed design work. In all .networks using the Neutrik Ethercon series of "with" <br> Lock connectors; all network devices in production and erection are consistent with international industry standards, including outsourcing some of them is the selection of industry leading products such as "HP" and "Linksys ."or" 3Com ", effectively enhanced <br> System of high level and stability; junction box includes various circuit of strong electricity output and signal transmission power interface, with international advanced production technology, eliminates any signal interference asked <br> Problem. Wire ., connectors are in line with international electrical certification, retarding wire have been; cable and Connector for connection requires the use of welding technology for processing, complete elimination of spark plug; global routing according to the <br> Studio of architecture and the circuitry layout .standards, reasonable layout, unified planning. Full show TV modern, automated lighting control system for advanced, flexibility and stability. <br> <br> 3. system hardware <br> <br> Television stations in the network Burean STRANDShowNET lighting control system ., mainly consists of the following parts: ⅰ ⅱ dimming platform network node ⅲ PC computer <br> <br> ⅳ network distributor ⅳ networked dimming Silicon Cabinet <br> <br> Dim table as the center of the entire system, and also the .action interface.

Backup to network infrastructure and console connection and to use fully tracked by <br> (FullTrackingBackup) mode on the console. That is, two dimming platform parallel processing, at any stage, .the key is another quick learning, performing synchronization output signal. This kind of "fully tracked by <br> A" traditional "hot backup" operation that is first in the host programming, and then on to a floppy disk, and then on to .back up the stage, once thePerformances will be needed from the middle of failed backup Taichung emergency operations out of die <br> For comparison, with greater effectiveness and security. Remote control computer-based control console of the control console, in the large performance .often available through the Division of labour to deal with, such as the host for the traditional lamp control, a control console for the color picker control, etc. <br>, You can set function to create a second or even third or fourth control .input to the system as a console role. In remote control mode, each console has its own independent input and display <br> And the control circuit data for "Partitioned" (segmentation) and recorded. This feature allows a console independent record control circuit .of the primary CUE farm, while at the same time, other users may <br> Use their loop segmentation and performs in the same CUE farm. With the display of all alone and the only loop list, each console loop segmentation can be any part .of the overall system, thus to meet the stage <br> On a variety of needs. The operation is absolutely flexible and maneuverability is strong, able to cope with different performance needs change. <br> <br> The advantage of this design is .that it uses a network of multiple level backup structure, thus ensuring that the system runs perfectly. Also featured is the network node in the network for electricity, which facilitates the lighting load and <br> Site move, avoiding the long distance transmission signal attenuation .effects.
