Simplicity ensured to a distributed control system for buildings, reduced costs through the constructive solution of multifunction controllers, configurability of control functions implemented al the level of multifunction controller, ease of instalation, operation and maintenance, fiability and precision of control due to use of digital sensors, automatic selection of local control functions, remote control and monitoring functions using the communication network
The invention relates to a distributed system for buildings, which implements lighting control, with light intensity variation, and temperatures control, using digital sensors. The system is implemented with multifunction controllers, identical from constructive point of view, which communicate into a network.
Distributed control system implemented with multifunction controllers, identical from constructive point of view. A controller is compound from control interface connected to a continous power supply, a single processor which firmware implements blocks for data coding and decoding, for lighting control, with light intensity variation, for temperature control using digital sensors, the processor keeps into internal memory working related and configuration informations, assigned for the selected control function, a group of optocuplers and the group of control outputs which are connected to main power supply line, each output drives electrical loads like electrothermic actuators, relay coils, bulbs with incandescent filaments; a group of 10 digital multifunctional inputs connected to push buttons, electrical contacts, or digital temperature sensors; for lighting control with light intensity variation a zero crossing detection device is connected; a group of 6 unassigned digital inputs connected to electrical contacts, an inputs conditioning interface, interface for displaying the status of outputs and a group of light emitting diodes. Multifunction controllers are connected into a communication network, for the purpose of monitoring and remote control functions implementation.
