  • a well-designed EMS can reduce not only the number of hours the system is used each day, but can also reduce the average power required.
  • the EMS can set back the HNAC temperature whenever a room is not rented and, when rented, whenever a guest is not in the room.
  • the EMS will turn off lamps and lights when the guest or housekeeping leaves the room.
  • the EMS can turn off the television when the room is not rented, and it can open or close the drapes to control heat exchange with the outside.
  • the EMS is part of a larger guest room control system, which also includes direct digital control (DDC) of the HNAC system, guestroom controls and a central electronic lock system (CELS).
  • DDC direct digital control
  • CELS central electronic lock system
  • the guestroom controls allow a guest to remotely control the lamps, lights, drapes, television, and other appliances from a single control station.
  • the CELS connects guestroom doorlocks to a central computer in the hotel for logging keycard access operations and for enabling and canceling access cards.
  • Guest room control systems are typically comprised of a control computer or device for each room.
  • the control computer receives data from various sensors throughout the room and, in response to the feedback provided by the sensors, operates a number of remote room control devices.
  • remote sensors include, for example, motion sensors, temperature sensors, smoke detectors, and door and other closure switches.
  • remote room control devices include, for example, thermostats and associated relays for heating, ventilation and air conditioning (HNAC) equipment, electronic locks, lighting control switches and relays, and motors and switches for opening and closing drapes.
  • HNAC heating, ventilation and air conditioning
  • the central control computer uses the data and control devices to, for example, adjust the room's temperature, determine and annunciate whether the room is occupied or unoccupied, determine and annunciate whether the room's mini-bar has been accessed, sound fire and emergency alarms, turn lights on or off, permit or deny access to the room, open and close drapes, turn audio-visual equipment on or off, and perform other functions related to controlling equipment or annunciating status in rooms.
  • the central control computer located in each room can be tied to a single master central control computer.
  • the central computer from each room provides data to the master central control computer from which such data is disseminated to display and control terminals at housekeeping, front desk, security, engineering or any number of other locations in order to provide hotel personnel with access to the data and with the ability to remotely control various room functions or settings from such terminals.
  • a telephone console fitted with a touch screen acts as the control computer for the room. It obtains room temperature information from internal sensors, target temperature information from the guest through the touch screen, and room status information (rented/vacant) from the master central control computer via a twisted pair of low voltage wires connecting all of the rooms through a network structure.
  • the control computer decides if the various appliances in the room should be adjusted and controls the appliances by providing control signals to the appliances accordingly.
  • Such guest room control systems work well to provide conveniences to the guest. For example, a guest can control many functions in the guest room through a bedside telephone console. Such guest room control systems also provide convenience to housekeeping staff. For example, a housekeeper would simply refer to the screen on the master central control computer to determine if the guest room was occupied or if the minibar needs re-stocking. Moreover, guest room control systems work well to conserve energy in a guest room. However, modern guest room control systems have limitations as well. Applications that depend on a faster and unconditional link to the master central control computer, such as digital video, cannot be implemented under this architecture. To overcome this limitation, additional data lines are required to be installed. However, the installation of additional data lines in an existing hotel is expensive and increases the maintenance required for the hotel.

  • Operating system 176 also includes various device drivers and a network layer process 262 for handling network layer protocols (e.g., the CINET protocol used in Inncom International Inc. commercially available guest room control systems) used in legacy guest room control system 126.
  • Process 264 is a laptop traffic management process, which allows microprocessor 168 to manage any traffic from guest laptop 20.
  • Process 266 is a legacy data management process, which allows microprocessor 168 to manage all of the legacy data (e.g., CINET frames) received on the secondary Ethernet port 112 (i.e., via LAN 55).

  • Process 270 routes traffic to and from the various room devices 18 and 30.
  • Process 272 is a database image creation process that updates the room process image 180 every time the smart router 50 receives information from the room devices 18 and 30.

  • 82 and LAN 55 or PMS 74 is accomplished at the application levels of primary and secondary network processing systems 152 and 154. That is, data communication between LAN 63 or modem 82 and LAN 55 or PMS 74 is handled by applications 164 and 178. As can also be seen in Figure 4, data communication between portions of legacy guest room control system 126 is accomplished between network layers processes 209 and 262. In other words, smart router 50 acts as a network layer bridge between portions of legacy guest room control system 126.
  • Each frame includes a frame header containing addressing information for a specific room gateway 28 and a specific device 30, a frame sequence number, a control flag that can disable a reply to the frame, and a field that defines the type of the frame (e.g., query by smart router 50, query by room gateway 28, response by smart router 50, or response by room gateway 28).
  • Smart router 50 can off-load data to a device 30 via room gateway 28 by using a series of query frames with their control flags set to disable any reply. For example, when a guest checks in to hotel 14, a desk clerk enters guest information into a terminal (not shown) connected to PMS server 74. The guest information is stored as a record in the PMS server 74, and the PMS server 74 provides the data to smart router 50 via serial port 108.
  • Room status process 274 receives the data via sockets layer 250, stores the data in non- volatile memory, and initiates the transfer of room status data to EMS 32 by calling traffic separation process 270.
  • Traffic separation process 270 establishes a link with room gateway 28 over LAN 55 and sends frames containing the room status information to the room gateway 28 via LAN 55.
  • Room gateway 28 strips the header from the frame and determines the destination of the device 30.
  • Room gateway 28 then converts the data from the packet into a protocol understood by EMS 32 (e.g., Inncom International's IR5 protocol as described in U.S. Patent Number 5,128,792).
  • EMS 32 accepts the data and acts according to preprogrammed, rented-status logic. For example, EMS 32 may switch the room heating or air conditioning system from an energy savings mode to a guest comfort mode.
  • Room status process 274 periodically resends room status data to EMS 32.
  • EMS 32 Upon the guest's check out, the process is repeated with PMS providing the guest information to the smart router 50, and room status process 274 providing the room status data to EMS 32.
  • PMS providing the guest information to the smart router 50
  • room status process 274 providing the room status data to EMS 32.
  • EMS 32 accepts the data and acts according to its pre-programmed, vacant- status logic. For example, EMS 32 may switch the heating or air condition system from the guest comfort mode to an energy savings mode.
  • smart router 50 can query a device 30 via room gateway 28 using one or more frames having their control flags set to enable a response. Upon receiving these frames, room gateway 28 will strip the header from the frame and send the data to the appropriate device 30. Room gateway 28 saves the frame sequence number in anticipation of the response. Upon response from the device 30, room gateway 28 encapsulates the response data within a frame and includes the frame sequence number in the appropriate field. Upon receiving the frame, smart router 50 identifies the response using the frame sequence number and processes the response data from the frame.
  • Devices 30 may be configured to provide an event message in response to some event within room 12.
  • An event message may include the opening of a door to minibar 34 or operation of door lock 36 by someone in guest room 12, for example.
  • room gateway 28 Upon receiving such an event message, room gateway 28 encapsulates the event message into one or more frames. Each frame includes addressing information from the device 30. Room gateway 28 sends the frames to smart router 50, which uses the addressing information to determine the origin and appropriate response to the event message.
  • the query and reply frames are also used to synchronize data stored in smart router 50 and room gateway 28. Synchronization is performed periodically, as initiated by the room status process 274 in smart router 50.
  • Room status process 274 initiates a query containing a number of attributes (parameters) that impact on the operation of guest room 12. These parameters are retrieved from the room process image 180 for the particular room 12 and from the hotel process image 182 for the hotel 18.
  • the parameters include, for example: rented status of the room, outside temperature, water temperature in the HVAC supply piping, system-wide energy demand situation, fire condition (i.e., if a fire alarm has been activated), central
  • the query frames contain a number of attributes that indicate status information from the guest room 12.
  • occupancy status i.e., if the room is unoccupied or occupied by the guest or by staff

  • Hotel process image 182 includes hotel- wide information such as outside temperature, water temperature in the HVAC supply piping, system- wide energy demand situation, fire condition (i.e., if a fire alarm has been activated), and central HVAC settings.
  • the information in hotel process image 182 can be changed remotely from remote server 84 via VPN 86 router 66 and LAN 63. Remote changing of hotel- wide information, in conjunction with the synchronization process described above, allows an operator at web browser station 90 attached to remote server 84 to alter the configuration of devices 30 in one or more hotels 14. This feature is particularly important for a remote server 84 that services a number of hotels 14.
  • remote server 84 by changing the system-wide energy demand situation setting, can change the power consumption in hundreds or thousands of rooms 12 simultaneously. hi effect, remote server 84 aggregates these rooms 12 into a single power consumer. As a single power consumer, the operator of remote server 84 can negotiate with electric utility companies for better power rates in exchange for promising to lower power consumption during peak demand times.
  • Data from hotel process image 182 and one or more room process images 182 are periodically provided by microprocessor 168 in secondary network processing system 154 to microprocessor 156 in primary network processing system 152. This data is then stored in FIFO queue 166. If the smart router is constantly connected to remote server 84 through LAN 63, router 66 and VPN 86, the data is sent immediately to remote server 84. If the connection is of the dial-up type, smart router 50 periodically establishes a connection with remote server 84 via modem 82 and VPN 86. This data can be viewed through web browser station 90.
  • remote server 84 In addition to receiving off-loaded data from smart router 50, remote server 84 is able to provide data to any individual device 18 or 30 in room 12. To accomplish data transfer to devices 18 or 30, remote server 84, smart router 50 and other information servers 64 are provided with a network address translation (NAT) table 184 such as that shown in Figure 5.
  • NAT network address translation
  • NAT table 184 is a mix of static (persistent) data and dynamically acquired data, hi NAT table 184, "Room Address” is the logical room number, which is used as the real address for applications. "Wiring Address” indicates the port number of the floor switch (hub) 58 to which the room hub 16 attached. "Suite ID” indicates a grouping of room hubs 16 for servicing a guest suite. "CINET Address” indicates an address for a legacy guest room control system. "MAC Address” indicates a medium access control address assigned to a specific device 18 or room gateway 28 in room 12. “ff Address” indicates an Internet protocol address for a device 18 or room gateway 28 (or an application in device 18).
  • Device Type/Status identifies the device 18 or room gateway 28 and indicates whether the device 18 or room gateway 28 is present on the network

Moreover, centralized guest room control system 10 allows any number of rooms to be aggregated into a single power consumer. As a single power consumer, the operator of centralized guest room system 10 can negotiate with electric utility companies for better power rates in exchange for promising to lower power consumption during peak demand times.
