Presupposition for stadium lighting control

Characteristics of lighting control Although the lighting control of the comprehensive stadium is flexible, it still has certain rules to follow. Generally speaking, there are several lighting control modes as follows: 211 single control means that the minimum number of lights is the basic unit, and each unit can be independently switched. Since the understanding of the basic unit is different, the practice is different. Some lights are used as a basic unit, while others have a set of lights as a basic unit. The number of lamps in each group of lamps is small or small, ranging from 2 to 3 lamps, and more than 6 to 9 lamps. This depends on the specific lighting conditions and function. From the actual use situation, we believe that it is not advisable to use one lamp as a basic unit. On the one hand, in terms of necessity, no matter what kind of sports or conference activities, it is impossible to use only one light. Even if the training light usually requires at least one set of lights or several sets of lights; on the other hand, economically speaking It is also inappropriate to use one lamp as the basic light-on unit. It will multiply the number of power supply circuits and double the number of electrical control components and piping wiring, resulting in unnecessary waste. For example, a gymnasium has a total of 154 iodine-tungsten lamps, and one lamp is used as the basic lighting unit, for a total of 154 units.

The scientific and intelligent intelligent lighting control system can detect and locate fault lights or damaged lights in the stadium by using integrated special software and hardware, and can prompt on the central monitoring computer screen. This is a maintenance and repair belt for large stadium lighting fixtures. It is very convenient. The control system can also be connected to a PC or Building Automation Management System (BAS) via an international standard interface and specialized software for monitoring, operating or modifying pre-sets of the entire lighting system, scientific management, and management of overlapping settings. system.

For the stadium lighting control system map. The system uses an intelligent lighting controller. Control all the lights in the above competition venue; control all the lights on the auditorium for the thyristor dimming module. We collectively refer to these two modules as functional modules. Each module is powered by a three-phase power supply, 12 single-phase outputs, and each output loop is directly connected to each group of lamps. The intelligent lighting controller can have 64 kinds of lighting scene pre-setting schemes, and the stadium only can be turned on by single control, centralized control, total control, etc., and only 14 schemes can be set to flexibly realize various lighting scenes. Presets to meet the lighting needs of venue cleaning, ball games, training competitions, gatherings, recreational activities and safe evacuation.

The system can automatically adjust the lighting of various venues in order of group to avoid large current impact caused by simultaneous lighting, thus ensuring the safety of electrical circuits and preventing voltage fluctuations of other power supply equipment. The system is simple and intuitive to operate. The user only needs to press a button on any operation panel in the auditorium entrance, the lighting control room and the movie screening room, and the system can automatically enter the preset state corresponding to the key. The system connects seven functional control modules with six operating panels through two pairs of common data lines to form a complete communication network. Under various working conditions, each module only responds to the network by “calling”. If a module fails, only the function related to the module fails, without affecting the normal operation of other modules in the network, the administrator can quickly find The point of failure is conducive to maintenance and repair.
