一、Design and effect of intelligent control system for public area lighting

After using the Shanghai DICON CNCOMATE intelligent lighting system, the lighting system can work in the fully automatic state. The system will switch several basic working states according to the preset settings, and automatically switch between various states according to the set time.

For example, when working in the daytime and the light is sufficient, part of the lighting will be automatically turned off to adjust to the most comfortable visual state; When the weather is dark, the indoor lights will be turned on automatically to keep the indoor illumination constant (according to the preset illumination value). When night comes, the system will automatically enter the "off duty" mode, automatically close some lighting circuits, and maintain the minimum monitoring and emergency requirements. In addition, the staff can also conduct on-site control through the manual panel.

At present, most of the high-rise residential buildings under construction and under construction have multiple entrances and exits for personnel and vehicles. Due to the large area and poor light of these corridors, a large number of lighting equipment are required for long-term lighting. If the normal control method is used, the required line is long and the circuit is complex. Because there is not a simple one-to-one correspondence between the exit and return routes, it is difficult to use a simple strong current control method to achieve automatic control of public area lighting. Generally, only continuous lighting can be used to form a "permanent light". In some places, although infrared or voice control switches are used to control lighting, automatic control can only be achieved for a small area (such as the entrance and exit of the stairs), but cannot be achieved for public area lighting. This not only causes huge energy waste and equipment loss, but also brings great economic burden to property management.
Investment effect:
Intelligent and convenient, it can provide sufficient lighting for the office building staff to enter and exit conveniently, quickly and safely.
Durable and reliable, stable performance, simple daily maintenance and management.
Energy conservation and environmental protection, significantly reduce operating costs, and improve the overall animal husbandry management and service image.
High return on investment and remarkable results.
2、 Specific implementation mode
The emergency lighting, walkway lighting I, walkway lighting II and toilet lighting of each floor are controlled separately, scene control and time control.
Shanghai Dikong CNCOMATE intelligent lighting can be preset according to different time of the day and different lighting scenes for different purposes (it can be set to full close mode, energy-saving mode, cleaning mode, normal business mode, and welcome mode). When using it, you only need to directly call the preset best lighting scene from the central control computer or the field panel. By opening and setting the timing function on the monitoring host (up to ten time modes can be set at the same time), the scene mode runs automatically without manual intervention, saving time, effort and energy. The lighting control in this area is centralized in the relevant management room, and the corresponding lighting can be controlled with the staff according to the specific situation.
Docking with security cooperation:
Shanghai DICON CNCOMATE intelligent lighting control system is equipped with fire emergency interface (AUX). A pair of passive normally open contact signals are introduced from the fire cabinet to the fire interface (AUX) of Shanghai Dicontrol CNCOMATE intelligent lighting system. When a fire alarm occurs, the fire signal is sent to the control module, which forces the control module to open the lighting circuit of the control module to facilitate escape. After the fire alarm, the fire signal is released, and the CNCOMATE intelligent lighting system of Shanghai Dicontrol automatically recovers to the lighting state before the fire alarm.
For example, the mobile infrared mobile sensor, intelligent control module and LED lamps are perfectly combined to form a unique intelligent light control system.
When the control system detects that someone is moving in the corridor and toilet in the area, the LED light is fully on, with a power of 15 watts and a luminous flux of more than 1080 LM. Its surface brightness is equivalent to the original 36WT8 fluorescent lamp (with a total power of about 42 watts), and the site has sufficient illumination; It is convenient for people to use. When people are moving in the sensing area, the light stays on. When people leave the sensing area (about 30s, adjustable), some LED enter the fully off state.

When the control system detects that there is no one in the area, the light is turned off. This method achieves a maximum power saving effect. Due to the integration of sensors and intelligent controllers, the concept of "lighting on demand" is truly realized; After the lamp is triggered to full brightness, there is a time delay (adjustable). Therefore, when people frequently enter and exit, the lamp will display continuous full brightness lighting to avoid discomfort caused by frequent changes in illumination.
