Description

Technical field

The technical solution relates to a home digital communication system, which essentially functions as an electronic doorman in the building in which it is installed. This means that it enables communication of the incoming person directly from the entrance to the object with the connected participants in the object, eventually also an automated entry of the incoming into the object by the contacted participant.

BACKGROUND OF THE INVENTION

At present, public address systems, such as larger households, housing units, hospitals and corporate buildings, use communication systems that require the connection of each subscriber to an electronic door harness with more than a minimum of five connecting wires.

These existing connections present a number of disadvantages. The main one is the necessity to build demanding cable routes and the associated high costs of implementing the system in the building. The complexity of the interconnection is also reflected in the later complexity of the service of current communication systems, which is given, for example, by the lack of clarity of the connection in the riser, the time complexity of troubleshooting, etc.

However, the current communication systems are also no longer satisfactory in terms of their design and customer requirements for their utility properties. It is practically impossible, for example, to extend the original number of subscriber telephones if the necessary design was not pre-designed in the system design. The communication systems used are often also problematic in terms of call transmission. E.g. When closing the home phone loop with the headset, there is feedback between the microphone and the loudspeaker, making communication impossible. The problem is also a breakdown of the telephone's plug, which, if not repaired immediately, may result in failure of the whole system and the possibility of damage to other electronic components. In connection with the above facts, subsequent complications arise with the control and monitoring of the entire system. For example, the current system does not notify the user in any way whether it has come from the entry panel to the subscriber or not.

The essence of the technical solution

The domestic digital communication system according to the present invention contributes to the elimination of the above-mentioned shortcomings. Its essence is that it consists of an outdoor panel containing, in particular, a set of subscriber buttons, a microprocessor control, speech circuits, possibly also an electric lock with a sensor of its function, whereby this panel is connected to individual subscribers via two wires.

In a preferred embodiment of the outdoor panel, a set of subscriber buttons is connected via an expander to a control microprocessor, to which is also connected an electric lock, a function sensor 1CZ 6044 Street of this electric lock and coding lock and service setup circuits, speech circuits, interface and power circuits.

Each of the subscriber phones preferably comprises a call decoder to which an electronic ringing element and a block of switching and powering circuits are connected, to which the speech circuits and the electric lock opening circuits are further connected.

The main benefit of the home digital communication system according to the present technical solution is, compared to the previously known communication systems, the simplicity of its connection via two wired buses and the associated system variability (more possibilities of connection and especially extension of the system to other subscriber phones) , its easy installation and low maintenance. This communication system is, for example, very easy to install wherever at least the bells have been installed as such (without the communication device). The possibility of using the existing bell duct as a two-wire system bus is particularly advantageous in buildings where there is no possibility of installing a new line - eg in historic buildings protected by the Heritage Office or in buildings where installing a new line is extremely technical and therefore costly .

BRIEF DESCRIPTION OF THE DRAWINGS

In order to clarify the essence of the solution, the attached drawings are shown, in which Fig. 1 shows a diagram of the overall connection of a home digital communication system in the building;

FIG. 2 is a block diagram of a preferred outdoor panel connection; FIG. 3 is a block diagram of a preferred subscriber telephone connection. Example of technical solution

The domestic digital communication system in the exemplary embodiment (see Fig. 1) consists of an outdoor VT board connected to the feeder N and connected via a two-wire S bus to individual subscriber phones DT-1 to DT- _1g2 ⁱⁿ apartments 1 to 192 object. (The VT outdoor panel may also contain a code lock - not shown in Figure 1). In this case, the number of DTs is 10 less.

Outdoor Repeater VT (see block diagram in Fig. 2) contains a set of buttons 1 subscriber (three blocks to B _12), which is connected through the expander to the control microprocessor 2 χ. To this control microprocessor 3 is also connected an electric lock 8, a sensor 6 of the function of this electric lock 8 and furthermore the setting and servicing circuits 4, speech circuits 5, interface circuits 7 and power circuits 9.

-2GB 6044 Ul

Each of the subscriber phones DT ^ to DT? (see block diagram in Fig. 3) includes a call decoder 10 to which the electronic ringing element 11 and the switch and power circuit block 12 are connected. Further, the speech and power circuit block 12 is then connected to the speech circuit 13 and the electric lock opener opening circuit 14. 8. The electronic ringing element 11 can be (according to the customer's wishes) a melodic generator, an electronic gong or a self-exciting piezo transducer or an optical bell for the deaf-mute.

The home digital voice communication system allows the incoming party to ring from the VT outdoor panel buttons to the relevant subscriber, the call between the called party (the subscriber) and the caller (the incoming party), and the electronic door opening; it is also equipped with anti-theft devices for the system components, means for remote fault detection and means for protecting the system against external voltage on the bus and signaling the bus interruption. The brain of the entire communication system is the control microprocessor 3, which allows, respectively. provides:

sensing the button 1 of the VT outdoor panel participant buttons pressed by the incoming person with a subsequent call (ringing) to the subscriber;

opening the door by operating the electric lock 8 to provide feedback to the subscriber;

- the function of the anti-theft subsystem of the VT outdoor panel;

- service circuitry and remote fault detection;

- controlling the direction of the call, excluding feedback;

- the function of the combined power supply circuits;

- a code lock function resolved from existing buttons and tableau illumination;

- short circuit or interruption check of S bus;

- expandability of the system by additional DT subscriber phones up to a maximum of 192 pieces.
