The invention relates to a method and system for monitoring room activity. A tray sensing device detects the presence of a tray in a given location and forwards the information to a tray 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 monitoring door lock and door tag information. Information from the tray sensing device, door lock/tag controller and is received at a room controller. The room controller of each room can include a wireless network to the tray controller, door lock/tag controller. The room controller can also monitor information of the room such as, for example, temperature information and light intensity information, and receive information regarding room activities, such as, for example, room service ordering, housekeeping minibar and checkout routine. Information from the room controller can be forwarded to a central information system. The central information system can display the information or activate an alarm. The alarm can be an audio or visual alert. The alarm can be deactivated upon removal of the tray from the given location or upon dispatching of personnel to the given location.

What is claimed is: 1. A method for monitoring room activity comprising the steps of: providing a tray sensing device for sensing a tray in a vicinity of the tray sensing device, said tray sensing device adapted for communicating tray information of the presence of a tray to a tray controller; providing a door lock, said door lock being activated by a door lock card, said door lock adapted for communicating door lock information of said door lock card to a door lock/tag controller; providing a door tag, said door tag including an associated RFID tag, said RFID tag adapted for communicating door tag information of said RFID tag to said door lock/tag controller; a room controller receiving one or more of said tray information from said tray controller, said door lock information from said door lock/tag controller and said door tag information from said door lock/tag controller, and associating a room address with said tray information, said door lock information and said door tag information; and forwarding said associated room address and said tray information, said door lock information and said door tag information from said room controller to a central information system. 2. The method of claim 1 further comprising the step of: activating an alarm at said host controller upon receipt of said one or more of said tray information from said tray controller, said door lock information from said door lock/tag controller and said door tag information from said door lock/tag controller, said room controller. 3. The method of claim 2 further comprising the step of: deactivating said alarm upon receipt of second information from a respective one or more of said tray controller, said door lock/tag controller, said door lock/tag controller and said room controller. 4. The method of claim 1 further comprising the step of: continuing to forward said tray information from said tray sensing device while said tray is at said given location until said tray is removed from said given location and deactivating said alarm when said information is no longer forwarded. 5. The method of claim 2 further comprising the step of deactivating said alarm upon dispatching of personnel to said given location. 6. The method of claim 1 wherein said tray sensing device further comprises a tray sensor coupled to a surface of said tray, said tray sensing device is positioned at said given location and said tray sensing device reads said tray sensor. 7. The method of claim 6 wherein said given location is a hallway and said tray sensing device is an antenna positioned in said hallway, said antenna reads said tray sensor. 8. The method of claim 7 wherein said tray sensing device and said tray sensor is respectively either a transmitter or a receiver for sending or receiving a signal. 9. The method of claim 1 wherein said door lock card includes a unique card entry code. 10. The method of claim 9 further comprising the step of storing said door lock information received at said central information system in memory of said central information system. 11. The method of claim 9 further comprising the steps of determining if said door lock card deactivated said door lock; if said door lock card did not deactivate said door lock, forwarding from said door lock/tag controller an identification of said door lock and said card entry code to said room controller; forwarding said identification of said door lock and said card entry code to said central information system; determining if said identification of said door lock and said card entry code are correct, if said identification of said door lock and said card entry code are correct, forwarding lock activation information from said central information system to said room controller; said lock activation information being used to activate said door lock card. 12. The method of claim 11 further comprising the step of monitoring power of a battery of said door lock with said door lock/tag controller; and if said power is below a threshold, forwarding an alert from said door lock/tag controller to said room controller. 13. The method of claim 1 further comprising the steps of: sensing room temperature information with said room controller; and forwarding said room temperature information from said room controller to said central information system. 14. The method of claim 1 further comprising the steps of: sensing room light intensity information with said room controller; and forwarding said room light intensity information from said room controller to said central information system. 15. The method of claim 1 further comprising the step of: navigating a screen display of said room controller for inputting room information at said room controller; and forwarding said room information to said central information system. 16. A system for monitoring room activity comprising: a tray sensing device for sensing a tray in a vicinity of the tray sensing device, said tray sensing device adapted for communicating tray information of the presence of a tray to a tray controller; a door lock, said door lock being activated by a door lock card, said door lock adapted for communicating door lock information of said door lock card to a door lock/tag controller; a door tag, said door tag including an associated RFID tag, said RFID tag adapted for communicating door tag information of said RFID tag to a lock/tag door; and a room controller receiving one or more of said tray information from said tray controller, said door lock information from said door lock/tag controller and said door tag information from said door lock/tag controller, and associating a room address with said one or more of said tray information, said door lock information and said door tag information; and means for forwarding said associated room address and said tray information, said door lock information and said door tag information from said room controller to a central information system. 17. The system of claim 16 wherein said tray controller, said door lock/tag controller, and said door lock/tag controller are connected to said room controller with a wireless network. 18. The system of claim 16 further comprising: means for activating an alarm at said central information system upon receipt of said one or more of said tray information from said tray controller, said door lock information from said door lock/tag controller and said door tag information from said door lock/tag controller, said room controller. 19. The system of claim 18 further comprising: means for deactivating said alarm upon receipt of second information from a respective one or more of said tray controller, said door lock/tag controller, said door lock/tag controller or said room controller. 20. The system of claim 16 wherein said tray sensing device further comprises a tray sensor coupled to a surface of said tray, said tray sensing device is positioned at said given location and said tray sensing device reads said tray sensor. 21. The system of claim 20 wherein said given location is a hallway and said tray sensing device is an antenna positioned in said hallway, said antenna reads said tray sensor. 22. The system of claim 21 wherein said tray sensing device and said tray sensor is respectively either a transmitter or a receiver for sending or receiving a signal. 23. The system of claim 20 wherein said door lock card includes a unique card entry code. 24. The system of claim 20 further comprising means for monitoring power of a battery of said door lock with said door lock/tag controller; and means for forwarding an alert from said door lock/tag controller to said room controller if said power is below a threshold.
