Sports venues can be classified in different ways according to different methods: According to the construction area, they can be divided into: main competition venues, general competition venues, and supporting functional areas. According to functional requirements, it can be divided into: site lighting, general lighting, auditorium lighting, emergency lighting, architectural facade lighting and road lighting systems; according to competition items and level standards can be divided into: lighting during competition, lighting during training, live TV Lighting, usual lighting and so on.
No matter from which point of view, the standard illuminance, the function and the control method of illumination are not the same in these occasions.
1, stadium main stadium
The control of lighting in the main stadium of the stadium is a functional, highly technical and difficult control system; it is necessary to meet the requirements of various sports competitions to the greatest extent, which is conducive to the optimal play of athletes’ technical level, and is beneficial to referees. The judgment of the government will help the audience to integrate the game and the game in a comfortable environment and enjoy the passion of the game. Especially in the real-time broadcast of color television during the game, we must be able to ensure the clear and vivid colors of the relayed images, and close-up close-ups of the athlete's special actions, good coverage of the audience seats and surrounding scenes and emergencies. The same effect, but also to meet the use of theatrical performances, exhibitions, ballads and other occasions, but also to ensure the safety of the audience during the entrance, exit, and watch.
To achieve these functions, we must first do a relatively accurate calculation of the effect of lighting, in order to maintain the lighting of the entire competition lighting, lighting quality and stability, which requires lighting vertical illumination, uniform illumination, three-dimensional, color rendering index Ra, The color temperature of the light source should reach a certain standard, and understanding of the light source and luminaire and how to complete various controls. The lighting of the comprehensive stadium should be suitable for the competition, training and other use requirements of various types of sports. In many cases, the playing field is not only a piece but two or three pieces of space are simultaneously in progress; in addition, the same kind of match is played on the same field. The lamp mode is also different at different time periods. Such as: audience entry, opening, preparation for the competition, formal competitions, breaks in the field, end of the breakouts, etc. For the control of each scene, if the traditional lighting mode has been more difficult to accurately represent the requirements of each game scene; The lamp status is used for real-time monitoring and centralized timing control; this is also difficult to achieve with conventional control equipment.
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-close mode, television broadcast mode, professional training mode, international competition mode, and domestic Game mode, auditorium lighting mode, emergency lighting mode.
2, stadiums general competition venue
Other venues are mainly used for general competitions. According to the different items and levels of the competition, the basic control modes for each venue are: competition mode, television broadcasting mode, training mode, audience entry and exit fields, cleaning mode, and emergency lighting mode.
At the same time, due to the particularity of lighting control in the arena, the following functions have been added to its control strategy:
In order to reduce the starting current of the entire circuit, each luminaire or each luminaire to be started in each mode is started in order. l Other control systems can be remotely controlled via the interface as required.
The statistical record records the use time of each luminaire or group of luminaires, estimates the lifetime of the luminaires, and reports in advance the luminaires that need to be replaced for the upcoming lifetime.
The luminance sensor detects the illumination of the venue, and records and displays whether the illumination required by different levels of lighting scenes meets the requirements. If it fails to meet the requirements, an alarm is reported and the switch status of the light set is promptly changed.
3, supporting functional area lighting control
Parking and entrance
Intelligent lighting system control panel is installed in the entrance management office of the garage, which is used for the manual control of the garage lighting. Under the control of the central control system of the system, the garage lighting is under automatic control. Garage lighting is divided into several states according to usage: official competition, training period and other time. At night when the official competition is in progress, the vehicle is busy and the garage lighting is fully on. During the day, due to the sunlight, the illumination can be appropriately reduced and energy consumption can be saved. When you are not racing, only turn on the lane light. If you need to observe the vehicle, you can turn on the local lighting on the spot and close it after the delay. The area of ​​the channel adopts a smart mobile detection sensor. When a person or a car moves, the corresponding local lighting is turned on. After the vehicle is parked or the person and the vehicle leave, the light is turned off and delayed. When the car moves, it can be displayed by the host. Facilitate the management of security and management personnel. According to the actual lighting and the use of the vehicle, the lighting of the day can be divided into several periods, such as five hours in the morning, noon, afternoon, evening, and late night. Through the software settings, the number of automatic opening and closing of the lamps during these hours is controlled. In order to achieve different illumination in the control area for lighting, so that the lighting has been effectively used, which greatly reduces the power waste, while protecting the lamp, extending the lamp life. If you have special needs, you can manually turn on or off the lighting in the management room with the key panel. When the external conditions meet the requirements of automatic control, the system will automatically return to automatic operation without manual reset.
Dressing room and home and away team lounge
The use of infrared mobile sensors, such as automatic lights when someone enters, the delay after the person left to close. At the same time provide central monitoring, according to the specific circumstances of opening and closing the relevant lighting. Provides automatic and manual switching control, switching from automatic sensing control to on-site manual control as needed.
Office area Because of the large office area, the entire office can be divided into several independent lighting areas. Use the scene control panel to turn on lighting in the corresponding area as needed. Due to the large number of entrances and exits, it is necessary to achieve more control within the office and to facilitate the use of personnel. That is, all the lights in the entire office area can be turned on and off at each entrance and exit, and lights in nearby office areas can also be easily controlled as needed. At the same time, it can be controlled according to the time, for example, the light is automatically turned off at 8 o'clock in the evening. If someone works overtime, it can be switched to a manually controlled switch light. Office lighting can be integrated into the central monitoring computer for monitoring.
corridor
With automatic lighting control, normal working hours are fully open, and non-working hours are changed to only a part of the lights. When no one is on holiday, only a small number of lights can be used as basic lighting. Each entrance is provided with a manual control panel, which can be manually controlled according to the needs of the nearby light switch.
staircase
Staircases use timing control and infrared movement control. During the competition, all of them are turned on. The infrared movement control mode is activated at ordinary times, and people automatically turn on the lights. After the people leave, they are turned off and turned off to save energy.
Public access
When an official game is played, all of them are opened so that the audience can enter and exit. After the end of the game, the audience will be closed after leaving. This operation can be controlled locally on the spot, or controlled by a central monitoring computer, and time control (such as basketball game) can also be set. At the same time, according to the actual flow of people to decide what kind of way to control, the entire control point is placed in the duty room or the corresponding functional room, in order to prevent the audience or non-permitted staff from operating at will.
Toilet
All the restrooms are controlled by infrared movements. People automatically turn on the lights, and the lights go off. The control method can be changed as needed. For example, when the audience is large, the system changes its lighting state to constant light, and switches to automatic sensing control when the number of people is small.
Front office (including ticket office and entrance hall)
When the official game is played, all of them are opened to facilitate the entry and exit of the audience. After the end of the game, the audience is closed after leaving. The lighting control in this area is concentrated in the relevant management room, and the staff controls the corresponding lighting according to the specific conditions. The operation can be controlled locally on site or controlled by a central monitoring computer. Time control can also be set.
Auditorium
Local control and computer control are two kinds of control methods. During the match, according to the conditions of sunshine, with the game process controlled by the computer or through the time sequence, such as at night large-scale activities (opening or closing ceremony or large-scale theatrical performances, etc.) scene lighting requires auditorium lighting to cooperate, can be through the computer Pre-booked scenes undergo unified changes to achieve a rich lighting mix. At the same time, the local control scene panel is set to control the illumination of the auditorium in the relevant area on demand.
Function Room
The multifunctional hall uses local control and provides remote control, scene control and other control methods. Some of the important multi-purpose halls can also provide dimming control to achieve the fading and fading of the scene, the gradual change of light. It can realize switching, automatic dimming of lamps (including incandescent lamps, spotlights, fluorescent lamps, and energy-saving downlights) as well as scene control, centralized monitoring and timing control. It can also cooperate with other multimedia systems (TV, AUDIO, AIR CONTROL, etc.) to achieve single-key operation and realize the combined environment scene control of lighting and corresponding functions.
Roof lighting
The scene mode is used to control the lighting, and the scene switches under different lighting modes are set by the computer. The lights involved in various modes are set to be turned on in sequence; they can be controlled independently, and can also be composed of lighting in different areas such as lighthouses and auditoriums. The scene moves at the same time. To facilitate maintenance, local control is provided and each lighting point can be controlled accordingly.
VIP room
For some VIP rooms, dimming control and local control are also provided. Local control includes scene control, dimming control, and remote control. For the important VIP rooms or private rooms, touch screens are used to control the scene. The entire light adopts the dimming technology, so that the entire room's light fades and the scene lights fade in and out. Improve the overall room level. At the same time, it can cooperate with other multimedia systems to implement single-key operation and realize the combined environment scene control of lights and corresponding functions.
Functional room (eg gym, etc.)
The use of computer control and local control, according to their respective functions to divide the different lighting areas, the illumination of each lighting area can be turned on alone, but also through the need to set different lighting scenes to achieve scene lighting control.
Building Landscape Lighting
The landscape lighting of the entire building mainly adopts timing control. For example, the lighting of the entire landscape lighting is turned on at 6 o'clock in the evening, and some lighting lamps of landscape lighting are turned off at 10 o'clock. Only the necessary lighting fixtures are left after 12 o'clock. The specific time can also be automatically adjusted according to the changes in the length of day and night throughout the year and holidays. If special circumstances can be changed to special lighting control status, with the need to change. At the same time, there are also local control panels on the maintenance roads, which are convenient for maintenance or special local control.
Lighthouse lighting
Sports venues generally have four lighthouses. Each lighthouse has lighting fixtures ranging from a few dozen to a hundred lights. Each lighthouse is a control loop. The lighting control of the four lighthouses is controlled by a computer. Various scene modes, turn on different lights. In order to reduce the inrush current at the start, each mode is set to start in sequence. At the same time on the computer also for each light source to open the time statistics, when the light source open time reaches 80% of the rated life, prompts on the computer, to facilitate management personnel to prepare for replacement in advance. At the same time, local control is set in the equipment room on each lighthouse to facilitate maintenance and maintenance.
The opening and closing status of each circuit in the lighting of the entire stadium can be displayed directly on the graphic on the central monitoring computer, and the opening and closing of each circuit or the opening and closing of each group of lighting fixtures can be directly controlled by the computer. It can also record the lighting status of each circuit, open and close time, and count the total opening time of the entire luminaire to facilitate management and maintenance.
