I. Introduction

Modern large-scale comprehensive sports stadiums (hereinafter referred to as sports stadiums), which not only can meet various large-scale competitions and cultural performances, but also can undertake different large-scale exhibitions and gatherings; the museum is divided into main stadiums and general stadiums, usually They all include badminton halls, table tennis halls, volleyball halls, tennis courts, basketball courts and other venues.

Lighting is one of the important aspects of the stadium's function. The focus of stadium lighting is sports field lighting, which is competition lighting. Secondly, general lighting, auditorium lighting, emergency lighting, site lighting, building facade lighting and roads. Lighting system is an important part of stadium lighting; how to meet the scene lighting of various competition venues, unified treatment of each part of the lighting system, so that color temperature, illumination, glare, color rendering index have reached the prescribed standards; It is the choice of lamps and light sources. It also depends on the choice of control system and how to arrange the coordination of various parts to accurately express the requirements of various competitions. The intelligent lighting management system is a modern comprehensive function stadium. The necessary choice.

Sports venues usually have the characteristics of multiple lighting circuits, high power, and scattered lights, and different scenes are needed to meet the functional requirements of different occasions.

The traditional lighting circuit is connected from the circuit breaker to the switch to the luminaire. Because there are many circuits in the stadium, there are many cables to the control room, so the bridge size is getting bigger and bigger, and at the same time, many wires and bridges are consumed.

The output relay of the intelligent lighting control system is installed in the distribution box together with the circuit breaker. Multiple distribution boxes are distributed in various places in the stadium area. Five types of twisted pairs are used to connect multiple distribution boxes. The five types of twisted pairs are connected to the on-site control panel and then connected to the control room. In the control room, panels can be used to control the lighting of the entire stadium. In this way, a large number of wires and bridges can be saved.

In the traditional way, if the complex functions such as multi-point and regional control are realized, the circuit is particularly complicated; and the intelligent lighting control system realizes the functions of multi-point control, regional control and the like, and the circuit is very simple.

l Scene control

In the public area, the control of the light area is performed according to the preset scene through the scene control panel, and the opening, closing, and time delay can be defined, for example, the automatic delay is turned off after the light is turned on.

l Timing control

In some public areas, the time of the light can be controlled according to the normal working time, so that the lights can be turned on and off periodically.

l Infrared mobile control

The infrared motion sensor automatically controls the lighting of public areas (such as corridors, lounges, stairwells, etc.), and the working status can be changed by the central monitoring computer according to actual needs.

l Field panel control

Each light zone can be controlled not only automatically (timed or computer), but also on-site control to facilitate the automatic (timed or computer) state of the local control light switch state when a special situation occurs.

l Centralized switch control

Through the monitoring software with graphic display used on the central monitoring computer customized for the stadium, the end user is provided with a simple and clear interface, easy to operate and friendly graphical interface, so that non-professionals can also use normally, control each lamp. Or each set of lights is turned on and off.

l Group combination control

Through the central monitoring host, all the lighting points can be combined and controlled by large scenes. During the holidays, the lighting of the whole building can be transformed by the preset lighting effects to form the overall effect change of the entire building lighting.

l Linkage with other systems

Through the interface, it can be linked with other systems (such as building control, fire protection, security, etc.), and the entire lighting system and other systems can be controlled according to specific needs.

l Wide area control

According to the needs, the working status of the entire lighting system can be remotely monitored through the Internet or a mobile phone.

Stadiums can be classified differently in different ways:

According to the construction interval, it can be divided into: main competition venue, general competition venue and supporting functional zone.

According to functional requirements, it can be divided into: site lighting, general lighting, auditorium lighting, emergency lighting, building facade lighting and road lighting systems;

According to the competition items and level standards, it can be divided into: lighting during competition, lighting during training, live TV lighting, and usual lighting.

Regardless of the angle of view, the standard illuminance values, usage functions, and control methods for these occasions are not the same:

1. Main venue of the stadium

The control of the stadium main venue lighting is a functional, technical and difficult control system; to meet the requirements of various sports competitions, it is conducive to the best performance of athletes' technical level and is beneficial to the referees. The political judgment makes it possible for the audience to watch the game and the game in a comfortable environment, and enjoy the passion of the game. In particular, in the real-time broadcast of the color TV during the game, it is necessary to ensure that the broadcast image is clearly transmitted and the color is vivid. The close-up shots of the athlete's special actions, the auditorium and the surrounding scenes and emergencies can be well reported. The same effect must be satisfied with the use of performances, exhibitions, singing competitions, etc., as well as ensuring the safety of the audience during the entry, exit and viewing.

To achieve these functions, we must first make a more accurate calculation of the effect of the illumination to maintain the illumination of the entire area and the quality of the illumination. This requires vertical illumination, uniform illumination, stereoscopic perception, color rendering index Ra, The color temperature of the light source should reach a certain standard, the understanding of the light source and the light fixture and how to complete various control. The lighting of the integrated sports venues should be suitable for the competition, training and other use requirements of many types of sports. In many cases, the venue is not only one but two or three venues are being carried out at the same time. Moreover, the same competition is performed on the same venue. The mode of the lights varies from time to time. Such as: the audience enters the scene, the opening, the preparation of the game, the official competition, the rest of the field, the end of the field, etc., the control of each scene, if the traditional lighting mode has been difficult to accurately represent the requirements of each game scene; how to the venue Real-time monitoring and centralized timing control with lamp status; this is also difficult to achieve with conventional control devices.

The main venue is the main part of the stadium. According to the competition requirements, the main venue lighting is usually divided into 8 different lighting control modes: full-open mode, full-off mode, TV broadcast mode, professional training mode, international competition mode, domestic Competition mode, auditorium lighting mode, emergency lighting mode.
