Energy Saving System
The system comprises of a central control computer, which is connected through passive DirectBUS distributors to the control Modules. The control modules are located in the rooms or other selected areas to control.
The control modules are locally connected to the appropriate sensors and peripherals, in order to collect information or to activate devices.
a typical application, we may distinguish two types of control
modules: The room and the common modules. The room modules are
responsible for the room control, while the common modules are
responsible for the control of the other selected areas e.g. stairs,
breakfast room, lobby, machinery room, or other.
is a two-way digital communication path between the control modules
and the central computer. The computer sends control instructions to
all control modules and receives status information and data from
them. The physical connection is realized with UTP or FTP type cable.
The passive DirectBUS distributors facilitate the installation
and the transmission of the digital information.
multi-point interconnection may be freely designed as a star or loop
topology, to fit the building morphology.
room posses a module, which is connected to the local sensors and to
the controlled devices, such as the air-conditioning, the electric
switch box, or the television.
room module stores locally up to eight smart card access codes,
allowing up to eight different smart card holders the access. Usually
half of them are reserved for the customers and the rest to the
typical room has the following peripherals and features:
The common modules are installed in selected areas of the hotel to perform building management and also to provide fire detection. They are connected to the appropriate sensors, and also to the DirectBus. The critical areas are additionally connected to a separate fire alarm bus system to construct a redundant communication system. The following services are available:
detection is done using standard ionization type smoke detectors. Fire
alarm is provided using two redundant communication systems. The main
system is the DirectBus communication means. The redundant system is
realized using a separate utp line, interconnecting all the common
modules connected to smoke detectors, called fire alarm bus.
a typical installation, the room modules are not connected to the fire
alarm bus. Only the common modules, connected to smoke detectors
placed at critical areas usually have the double communication path.
The fire alarm bus ends in a specialized module, usually by the
reception. This module is also connected to the DirectBUS. The fire
alarm bus has functional priority over the DirectBUS, thus
implementing a robust design. This module has physical buttons to
pause momentarily the general fire alarm, though the horns connected
to the common module where the detector signaled an alarm, are
automatically and independently activated.
system may easily be adapted to any local fire regulations, using both
software and hardware modifications.
central computer provides constantly, a global view of any activated
smoke detector, or of any possible malfunction of the fire detection
central computer provides a global view of the hotel in real-time. At
the same time it creates logging files, where all the events that take
place in the hotel are recorded.
the hotel manager has full control over all the functional parameters
of the rooms and of the selected hotel areas.
access cards may be refreshed in real time for any individual room or
fire-alarm system is continuously monitored.
command, the log files may produce real time links to other hotel
managements applications, in order to transfer information, such as
billing information originating from the Pay TV or the internal credit
displayed information on the central computer screen is possible to be
relayed in real time on
another distant computer through LAN or Internet.
