1) Automatic control:
In common areas such as walkways and elevators, two-in-one sensors can be installed to monitor the illumination of the current environment and whether there is any activity, and to realize automatic control. In the case of sufficient illumination (such as sunny days, noon), someone or no one, the lamp will not light; in the case of insufficient illumination (such as rainy days, nights), someone lights on, people go, the delay lights out.
The illuminance sensor is installed in the window position of the classroom, the teacher's office and other functional areas, and the current illumination situation is monitored in real time. When the illumination is sufficient, the lamp in the window position is automatically closed, and the natural illumination is fully utilized.
2) manual control:
Each classroom, office door is equipped with Smart panel, which can realize manual control of room lighting. Panel can achieve one-to-one, one-to-many control.
3) scene control:
For the school landscape lighting, teaching building hall lighting, important conference room lighting can be based on the control needs of different scenes, set up a variety of scene modes in advance, and by the staff on duty one-click switch.
4) timing control:
According to the time of school early reading and next evening self-study, the system sets the timing switch to complete the automatic control of lighting and ensure the reduction of energy consumption during non-working hours.
5) computer centralized monitoring:
The computer end control page mainly has the home page, the floor control page composition. It can realize remote centralized control, feedback the switch state of field loop in real time, and facilitate remote monitoring of duty personnel.
Monitoring software consists of title bar, task bar and working interface. Title bar: mainly reflects the project name and time. Navigation bar (task bar): you can switch between any page, select. Work interface: according to the floor and room layout, the control is simply divided, can achieve single lamp control, multi-loop control and other control functions.
