Hotel Reservation System Interface to BACnet

If you're a developer of facility automation systems or controls for hotels and facilities that use BACnetTM communications software, chances are you've had a hard time finding ways to interface BACnet equipment with the hotel reservation system. If you've looked at the BACnet standard, you know that even simple communications functions can present some daunting problems, and you probably don't have the time to become that much of a BACnet expert. The hotel reservation system itself is probably proprietary and completely unfamiliar. You need a quick way to interface between popular proprietary hotel reservation systems and BACnet-based automation systems. You need BACroomTM.

BACroomTM is the industry's first easy-to-use BACnet interface for hotel reservation systems. BACroom runs under Windows 98/Me/NT4/2000 and XP, and provides a robust and proactively supervised interface tailored to the needs of BACnet designers.

BACroom uses our famous fifth-generation BACdoor Client technology to deliver fast and reliable performance. BACroom works with both Ethernet 8802-3 and ARCNET local area network types using NDIS-compliant drivers, and supports BACnet/IP. You can even use MS/TP through any standard serial COM port with an external EIA232-485 converter, or PTP through any standard serial COM port.

BACroom operates as a middle man between a hotel reservation system (HRS) and BACnet devices that control HVAC for rooms. Up to 2000 rooms can be configured at one time. Periodically, the HRS sends a message to BACroom that indicates whether a given room is vacant or occupied. BACroom periodically transmits this occupancy status, using BACnet, to BACnet-based HVAC controllers. Each room is configured to have a correspondence with one BACnet object property in one BACnet device. Each room may use a different BACnet device, object and property, and all are individually configurable.

The value that is poked to (written to) the BACnet device is configured by specifying a BACnet device instance, object identifier and property identifier. Array properties are not supported. The property to be written must accept an unsigned enumeration, or real, type of value and all of the rooms must use the same data type for values to be written. The value that is written typically represents 0=vacant, 1=occupied, but other values can also be used.

BACroom depends on receiving a message from HRS at a periodic interval to indicate that HRS is alive. This supervision can be disabled for HRS that do not provide supervision signaling.

A typical system connects the hotel reservation system PC (in this case Micros-Fidelio) on the same Ethernet LAN with the facility automation system using BACnet. BACroom communicates with Fidelio to get occupancy information and relays this status to BACnet device(s) using BACnet.

BACroom is designed to be customized for different kinds of HRS interfaces. A number of widely used interfaces for Ethernet, TCP/IP, and various serial port protocols are available without requiring customization. Please contact us for a custom quotation.
