Description

The invention relates to a central unit of a door communication system.

A method for controlling a door intercom is known from DE 102 54 273 B4, wherein the door station transmits a control signal via a network device to an apartment intercom, the network device or a switching unit associated with the network device converting the control signal into the KNX-EIB signal of the building bus system and transmits it to the apartment intercom through a bus coupler. The apartment intercom or switch unit associated with the apartment intercom receives the KNX-EIB signal from the bus system of the building using a bus coupler. The apartment intercom can generate a KNX-EIB signal through a microcontroller and connect to the building bus system via a bus coupler, after which the network device, after receiving this KNX-EIB signal, unlocks the voice signal transmission between the door station and the apartment intercom. In an embodiment of a door intercom comprising a door station, a network device and at least one apartment intercom, the door station is connected via a connecting line to a network device, and the apartment intercom is connected to a network device. The network appliance and / or the apartment intercom have a corresponding KNX-EIB bus coupler to which the building's bus system can be connected. Alternatively or additionally, the switching unit associated with the network device and / or the apartment intercom contains this bus coupler.

The basis of the invention is the task to offer an optimized central unit of the door communication system, which can additionally be connected to the building systems technology.

This task in accordance with the invention is solved using the Central unit of the door communication system containing

a door communication system interface for connecting door communication system devices, such as at least one door station and at least one home station, via a door communication system bus,

- the interface of building systems for connecting building system devices, such as actuators and / or sensors, via the building system bus,

- programmable evaluation logic connected to both the door communication system interface and the building system engineering interface, and

- a programming interface coupled to programmable evaluation logic,

- moreover, the programmable evaluation logic independently performs the functions of control and switching and

- converts events activated in one direction by the devices of the door communication system into the switching and / or control functions that must be performed by the devices of the building’s system engineering, in particular by the actuating elements,

- converts events activated in the opposite direction by devices of the building system engineering, in particular by sensors, into the switching and / or control functions to be performed by the devices of the door communication system.

In an embodiment of the invention, for configuring direct interaction between devices of a door communication system and devices of a building’s system engineering, the programming interface sets the order,

- what events in the building system equipment devices initiate functions in the door communication system devices and how these initiated functions should be performed in detail, and

- what events in the devices of the door communication system initiate the functions in the devices of the building system engineering and how these initiated functions should be performed in detail.

The advantages achieved by the invention consist in particular

- the possibility of universal combination of events of building systems engineering with events of the door communication system - without any restrictions,

- the possibility of programming the conditioned dependencies of the two communication technologies combined with each other, that is, the building systems technology and the door communication system.

By integrating the building systems interface into the central unit of the door communication system and by selecting the appropriate protocols, both the functions of the door station (s) and the apartment station (s) can be initiated through events related to the building systems. At the same time, it is possible, in a desirable programmable manner, also to initiate events related to the building systems from a door communication system.

The invention is further illustrated by examples, illustrated by drawings, which show the following:

FIG. 1 is a schematic diagram for communicating at least one door station of at least one apartment station, as well as actuating elements and / or sensors of a building system engineering, through a central unit of a door communication system,

FIG. 2 - an example of execution with a musical installation connected to the control device of the building systems engineering,

FIG. 3 is an example of execution with stairwell lighting / outdoor lighting connected to the actuating element of the building system engineering,

FIG. 4 - an example of execution with a timer built into the building system engineering,

FIG. 5 is an example of execution with a motion sensor built into the building system engineering.

In FIG. 1 is a schematic diagram for communicating at least one door station of at least one apartment station, as well as actuating elements and / or sensors of a building system through a central unit of a door communication system. The central unit 1 of the door communication system is shown, which contains

- interface 2 door communication system,

- interface 3 of the building systems engineering (interface device),

- programmable logic 4 ratings,

- programming interface 5.

At least one door station 9 and at least one home station 11 are connected to the interface 2 of the door communication system as devices of this door communication system via a bus 6 of the door communication system. Of course, any other door stations and / or apartment stations can be connected to the interface 2 of the door communication system or to the bus 6 of the door communication system, as shown by a dotted line in the figures.

Several actuating elements and / or sensors (switching or control devices) of the building system or devices 16, 18, 21, 22 of the building system, such as, for example, switching actuators or motion sensors.

The integration of the interface 3 of the building systems and programmable logic 4 ratings into the central unit 1 of the door communication system is of high importance. For this, the central unit of the door communication system, for example, the power supply unit, is expanded to the corresponding physical interface, and a suitable protocol stack is implemented. Programmable logic 4 evaluation can independently perform the functions of control and switching and

- converts events activated in one direction by the devices of the door communication system into the switching and / or control functions that must be performed by the devices of the building’s system engineering, in particular by the actuating elements, and

- converts events activated in the opposite direction by devices of the building system engineering, in particular by sensors, into the switching and / or control functions to be performed by the devices of the door communication system.

In general, a protocol stack in data transmission is understood as a conceptual architecture of network protocols, and individual protocols are located one above the other as stacked layers layers numbered in order. Each level uses a correspondingly lower level in the protocol stack to perform its specific task.

The following are a few examples to illustrate the various possibilities provided by the invention:

In FIG. 2 shows an example of execution with a musical installation connected to the control device of the building's building equipment. The user rings the doorbell of the house, that is, activates the doorbell button 15 of the door station 9. In order for the tenant not to miss the sound of the doorbell 12 of the home station 11, the volume of the running music installation 17 is automatically reduced. For this, the musical installation 17 is connected to the control device 16 of the building system engineering. The doorbell control signal (message) is sent via bus 6 of the door communication system not only to the apartment station 11, but also via the interface 2 of the door communication system, programmable logic 4 ratings, interface 3 of the building system engineering and bus 7 of the building system to the control device 16, which causes a decrease in the volume of the musical installation 17 in a programmable manner.

In FIG. Figure 3 shows an example of execution with staircase lighting / outdoor lighting connected to the actuating element (switching device) of the building system engineering. When leaving the house, the tenant presses the key 14 of the absence of the apartment station 11. Thus, the stairwell lighting / exterior lighting is automatically activated / turned on, but all other (or pre-installed) apartment light sources are automatically turned off. For this, stairwell lighting / outdoor lighting 19 and all (or pre-installed) light sources (or other electrical consumers or controlled functions) 20 of the apartment are connected to the actuating element 18 of the building system switching. The absence control signal (message) is received via bus 6 of the door communication system, via interface 2 of the door communication system, programmable logic 4 ratings, interface 3 of the building systems and bus 7 of the building systems to a switching actuator 18, which includes stairwell lighting / outdoor lighting 19 and turns off all (or pre-set) light sources / consumers / functions 20 of the apartment.

In FIG. Figure 4 shows an example of execution with a timer built into the building system engineering. The timer 21 sends a programmed time signal (message) "the beginning of a night's rest." In the morning, night rest ends with a signal (message) “end of night rest” of timer 21. These timer signals (messages) are received via bus 7 of the building’s system engineering, via interface 3 of the building’s system engineering, programmable logic 4 ratings, interface 2 of the door communication system and bus 6 the door communication system to the apartment station 11 and the doorbell 12 is automatically turned off there for a certain period of time between both timer signals (messages): “start of night rest” and “end of night rest” (silent adjustment circuit).

In FIG. 5 shows an example of execution with the motion sensor of the building systems engineering The motion sensor, which is built into the external area of the building’s system engineering, activates, as a result of the movement, a detection signal (message), which is received via the building’s system bus 7, through the building’s system 3 interface, 4 evaluation logic, 2 door communication system interface and 6 door communication system to the door station 9, whereby the camera 10 of the door station 9 is automatically turned on so as to register a possible unwanted visitor. After activating the camera 10 through the bus 6 of the door communication system, the display 13 of the home station 11 is additionally activated to be able to monitor the shooting from the camera.

The programming interface 5 is an important component for configuring the direct interaction between the door communication system and the building systems technology. Using the programming interface 5, the order is set:

- what events or incidents, incidents related to the building's building systems, initiate functions in the door communication system and how these initiated functions should be performed in detail, and

- what events or incidents, incidents related to the door communication system, initiate functions in the building systems engineering and how these initiated functions should be performed in detail.
