Description

The invention relates to a control system, in particular for a Building control, and a method for controlling consumers in one or more buildings or other real estate. It goes without saying that consumers can also be controlled who are not immediately located in the property. The control system according to the invention and In principle, the method can also be used in mobile devices find, such as in trains, caravans, ships and the like.

Two types of building control systems in particular are known today. Firstly, this is the generally known control by means of the circuit of relays for example for the control of lighting systems. The Control has a limited range of functions, since with it only Boolean links can be mapped, and the "data" consist exclusively of electrical impulses.

On the other hand, there are still little used today Building controls with intelligent components, in which the intelligent components are connected via bus lines. The disadvantage of these systems is that they are self-contained, and only special components - such as buttons, sensors, Consumer - can be used with one to the bus system suitable interface. This is the use of this Systems extremely inflexible, complicated to install, and it can be in usually no other existing control systems be involved, since these often do not have the required compatible Have interfaces.

The subsequent installation in a building proves to be particularly disproportionately difficult. Because only special, for the system bus compatible components can be used are the known  intelligent systems very expensive. Another significant disadvantage lies the fact that if one component fails, the entire system is disturbed.

The invention has for its object a control system, in particular for a building control system that can be used flexibly can, has a wide range of functions, works reliably and is inexpensive. Furthermore, a flexible, fail-safe procedure for Control of consumers, especially in and around a building being represented.

This task is performed by a control system with the characteristics of Claim 1 and a method having the features of claim 16 solved. The sub-claims describe further particularly advantageous Embodiments of the invention.

The control system according to the invention includes a basic system one or more modules. At least one module of the basic system is an active module.

For example, it is possible that the database system contains data and Control signals from the basic system or the logic system records and evaluates and develops behavioral patterns. at Any faults that occur in the basic or logic system become these Behavioral patterns are then used to generate control signals, which control the building or the consumer in such a way that Malfunctions do not occur. For example, the control of Roller shutter motors depending on the measured values of an outside house called lying light sensor. The electric motors as consumers are controlled by the control system so that when Darkness close the shutters. Now falls after a while Light sensor off, so by using the stored behavior patterns Shutters are still closed at the right time.  

The storage and evaluation of the data and signals of the basic system can also be optimized independently, for example one Optimization of the energy consumption of heating systems possible. Also the storage of functions in the database system with particularly high Security must be carried out or customized to individuals should be adjusted is possible.
