Lighting Overview of the construction Unit: The Sports center of Xinhua County is located in the entire peninsula region south of Baishazhou Road and north of Zishui of Xinhua County, north to Baishazhou Road, south to Yanjiang Avenue and flood prevention dike leisure scenic belt, Meiyuan South Road, Xuefu South Road through the north and south, Shengjiao Road connecting east and west, belonging to the modern large-scale comprehensive stadium. Its function should not only be able to meet all kinds of large-scale competitions, but also can undertake different large-scale artistic performances, gatherings and other tasks. The stadium is divided into the main court and the general court, usually including badminton pipe, table tennis pipe, volleyball hall, tennis hall, basketball hall, track and field hall and its supporting functional areas, etc. With a total construction area of 100,451 square meters and a span of 330 meters and a height of 129 meters, it can accommodate nearly 50,000 people. For the first time, the cable-arch structure of bridge engineering is applied to civil buildings. It is equipped with a standard circular track with a circumference of 400 meters, a standard football field and various field events, and is equipped with multifunctional lawn protection boards for holding large-scale cultural performances and commercial promotion activities of different scales. It has the largest open-closed roof in Asia. It is the largest, most complete and highest standard comprehensive open-closed top stadium in Inner Mongolia.

Lighting is one of the important links to fully embody the function of the stadium. The key point of the stadium lighting is the stadium lighting, that is, the competition lighting. This is followed by general lighting, auditorium lighting, emergency lighting, venue lighting, building lighting, interior lighting and road lighting. These are an important part of the stadium lighting; How to satisfy the scene lighting of various competition venues? Agree to treat each part of the lighting system so that the color temperature, illuminance, glare, color rendering index, etc. meet the specified standards. It is not only the choice of stapes and light sources, but also the choice and distribution of lighting systems. Accurately express the lighting requirements of all kinds of competitions, choosing intelligent lighting control system is the necessary choice of modern comprehensive functional stadium. Ii. Demand analysis: According to the above characteristics of the lighting system in this building and the usage characteristics of different functional areas, the functional requirements for the lighting control system are analyzed as follows: 1. As stipulated in TY/T 1002.1-2005 Requirements and Inspection Methods for Sports Lighting, the stadium requires different lighting effects according to different competition specifications and different competition types. For example, TV broadcast mode, no broadcast mode, international game mode, domestic game mode, training mode and so on. The control function is very complex, if the traditional manual control is very easy to appear misoperation, affect the game effect. Therefore, simple operation is needed to operate a variety of complex modes, fast, convenient, accurate, to prevent misaction; 2, for the rest hall, toilet, corridor, stairwell, equipment warehouse and other indoor auxiliary rooms, need to carry out automatic control of the lamp on and off; 3. For outdoor or well-lit areas such as entrance ramps and open lounges, in addition to the automatic control of lights coming on and off, the lights should also be turned off according to the outdoor illumination conditions. If the outdoor lighting is good, the lights should not be turned on; 4, conference rooms, VIP rooms, reception rooms and other high-grade rooms often need to undertake the reception of foreign guests and other important tasks, so it is necessary to have higher requirements for the lighting level. More functions such as scene dimming, mode control, wireless remote control, remote control, blinds and curtain linkage should be designed according to the application scenarios. 5, the stadium, indoor basketball court, badminton court, etc. have different modes of lighting control for games, cleaning, practice, etc.; 6. For the parking lot, flower bed and landscape lighting outside the stadium, the lights should be automatically turned on and off according to the sunrise and sunset time; 7. Monitoring and control of the overall lighting of the stadium can be carried out in the central control room to save a lot of manpower for monitoring and patrolling the lighting system; Iii. Corresponding solution: According to the lighting control system requirements of our museum and the characteristics of modern stadium lighting control system, the following scheme is designed to meet the above lighting control requirements. 1. By connecting the lighting circuit in the stadium to the intelligent lighting system, edit the switch and dimming mode of the lighting circuit and set the corresponding mode control panel to implement the lighting mode of different events according to the lighting arrangement effect of different sports events and performance tasks undertaken by the stadium. The mode control panel of the intelligent lighting system is an irreversible execution switch, that is, the same mode will be executed when pressed for several times, without misoperation. At the same time, the intelligent control panel has the indicator function, which can indicate the effect state of the field light, convenient field monitoring. 2, sports venues are public places, generally do not install control panel in public areas. By connecting the lighting circuit in the corridor and other public areas to the lighting control system, and installing a hot wire sensor in the appropriate ceiling position in the public area, by monitoring the temperature difference and displacement between the human body and the surrounding environment, the control of the public area circuit is realized, and the effect of lights on when people come and lights off when people go is achieved. 3, for the entrance ramp, open lounge and other outdoor or good lighting areas, can also use the hot wire sensor head with illumination induction ability, so that when the indoor illumination level is the same, even if people pass by, the lamp will not be lit, the maximum use of natural light energy saving. The sensor also has a delay setting function of 10 seconds to 30 minutes, which can be set arbitrarily according to the use of the controlled area, to eliminate the damage to the life of the lamp frequent switching lamp; 4. In order to highlight the control and management level and lighting level of the stadium, the meeting room, VIP room, reception room and other high-grade rooms of the stadium meet the needs of leaders and foreign guests. The lighting circuit can be connected to the intelligent remote control switch for control, and the dimming ballast of the dimming lamp can be connected to the dimming module for dimming control. Electric blinds are selected for blinds in the room, which are controlled by the motor module of the system. Wireless sensors are installed on the ceiling of the room, and the indoor lamps and blinds are remote controlled by guests from the seats. In its wireless remote control and the control panel on the wall, multiple modes such as meeting scene, rest scene and receiving scene are preset, so that guests or staff can carry out "one-click" operation. With scene dimming, mode control, wireless remote control, remote control, shutter linkage and other rich functions. Provide guests with more advanced and comfortable lighting experience, and a good meeting atmosphere. 5, according to the stadium has the competition, cleaning, practice, etc. to carry out different mode of lighting control needs; Different lighting circuits can be reasonably combined and allocated into different lighting control modes or groups to cope with the stadium's daily lighting competition, cleaning, practice and other different states, and the realization of these modes and groups can be controlled by simple Settings on the control switch. For example, the "cleaning" switch is set in the cleaning studio. When cleaning, the cleaning personnel press the "cleaning" switch, and the lamps are lit at intervals to maintain the visible state, while not wasting too much power. After the cleaning, the cleaning personnel return to their own studio to organize the items, and the "cleaning" mode is closed at the same time. This can easily do a person's duty, easy to control. 6, for the stadium location, landscape lighting is generally used in major holidays, or important games, some venues outdoor lighting is more flexible. It can edit the different effects of outdoor lighting into different modes in the central control room. According to the different needs of the outdoor scene of the stadium, the central control room can directly control, so as to facilitate the management of landscape lighting. 7. For the demand of centralized control and monitoring of the stadium, in order to monitor and control the overall lighting situation in the central control room, two options are provided. On the one hand, the control panel with the same number as the lighting circuit of the whole stadium is installed in the central control room; In this way, the switching state of each loop can be seen effectively and intuitively. On the other hand, the system is equipped with CNCOMATE central monitoring software (network control system); Through CNCOMATE software, the staff in the central control room can visually and clearly see the real-time switching status of each circuit in the stadium plan.
