What is the principle of passenger control system?

As for the principle of the guest control system, this is a matter of turning over books, but just before I was in charge of this work in our hotel, 1, the TV was controlled by the room card and my own high-voltage switch. 2. The wardrobe light is controlled by the room card and the wardrobe travel switch. 3. The system uses the weak point scattered reset switch to control the lighting and exhaust fan in the guest room. 4. When the guest pushes the door open, the porch light will light up automatically, and the time of the porch light can be adjusted. 5. After the guest inserts the room card, the corridor light will light up continuously, and the left/right bedside lamp will light up automatically. 6. When the guest presses the main switch, turn off all the lights. 7, infrared induction control lights, etc. Zunbao, Chem-Trend and Xiaomi are all first-line brands. If you want to be a hotel guest control, Xiaomi is a rising star. Chem-Trend and Zunbao have been established manufacturers for a long time, and there are service offices all over the country, which are all good. If you insist on which one I recommend, I will recommend Chem-Trend Intelligent.
