How does Shanghai Xunshi equipment realize hotel wake-up service?

The "morning call service" of the hotel is to call the guests to get up at the time specified by the guests in the morning, or to have dinner in the morning, or to have something important the next day. Wake-up service usually enables guests to sleep peacefully without worrying about oversleeping and missing important things. Xunshi equipment cooperates with the middle-layer software of the third-party hotel management system (PMS) to realize the information interaction between OM and PMS, and realize the functions of wake-up service, check-in/check-out, bill charging and so on. 1000 yuan can build a simple wine pipe system.
