METHOD AND SYSTEM FOR ROOM ACTIVITY COMMUNICATION

The invention relates to a method and system for room activity communication. In one embodiment, a tray sensing device detects the presence of a tray in a given location and forwards the information to a room controller. The tray can be a conventional tray for supporting food articles or can be supported or integral with a food cart. The system also includes a door lock/tag controller for monitoring door lock and door tag information. Information from the tray sensing device, door lock/tag controller is communicated to a room controller. The room controller of each room can include a wireless network to the tray controller and/or door lock/tag controller. The room controller can also monitor information of the room such as, for example, temperature, humidity and light intensity information, and receive information regarding room activities, such as, for example, room service ordering and status, housekeeping, minibar, phone messages and checkout routine. Information from the room controller can be forwarded to a central host controller for management of the information. The central host controller can display the information, activate an alarm or separate and send data to relevant controllers located, for example at security, service, housekeeping and front desk. The alarm can be an audio or visual alert. The alarm can be deactivated upon removal of the tray from the given location or acknowledgement of request.
