Intelligent Systems - Smart solutions for home and building automation

What is Smart-house?Smart-house systerm is a field bus systerm that offers unique solutions for a wide range of applications in building automation, water distribution, energy management and many other areas. The system is capable of transmitting multiple digital and analog signals over several km, via an ordinary 2-wire cable. And its modular design and simple operating principle enable even novices to implement in new or existing applications. Solutions are engineered by combining products from the wide range of Smart-house modules, including digital and analog I/O modules, PLC and PCinterfaces, user interface and Modems. All modules in an installation connect to the same 2-wire cable which is used to exchange data between modules and between a central controller and modules.The Smart-house signals can be transmitted not only on copper wire, but also on fiber optic cable, via radio modem, on leased telephone lines or via GSM Modem. Smart-house has proven its performance in more than 150,000 installations worldwide since 1986. And even though the latest ASIC technology is used today, the new Smart-house modules are still compatible with those installed 20 years ago

Why use Smart-house?Many criteria have to considered when selecting a fieldbus system. These include transmission dl-stance capabilities, easy operation, noise immunity, topology and response-time. And cost-effectiveness, of course, is always a factor. Therefore, it is important to define the key application requirements in order to optimize the bus system for the specific task. The strength of the Smart-house system lies in a unique set of features that enable elegant, flexible and cost-effective solutions for a wide range of applications. Most of these features orignate from the effective time-division multiplex technology used. The efficiency of the protocol allows a low carrier frequency of 1 kHz, providing long transmission dl-stance and superior noise immunity. Hence, Smart-house is capable of transmitting multiple digital and analog signals over distances up to 10 Km, via a non-shilded, non-twisted 2-wire cable, without using repeaters. These unique Smart-house features provide considerable cost savings in many installations, expecially when existing ordinary calbes are available for use. Another important characteristic is easy handing in all project phases.It does not take an engineering degree to work with Smart-house. No PC is required, since the coding of addresses and testing is carried out by means of slimple handheld devices. There is no need for special cables and terminations, and there are no cable routing restrictions as known from many other systerm. It is so simple and easy to implement, that many customers do their own installation, troubleshooting and maintenance, thus eliminating the need for costly and installation contracts. Smart-house is system independent and open for interfacing with basically any kind of controller. Serial interfaces with Modbus and Dedicated PLC protocols, together with gateways for Profibus-DP and Devicent, enable easy and flexible interfacing to PLCs, PCs and dedicated controllers.
