Description
INTERFACE DEVICE FOR COMMUNICATING BETWEEN ANALOGUE OR DIGITAL VIDEO DOOR ENTRY SYSTEMS AND TWO-WIRE MULTIMEDIA BUSES
The present invention refers to an interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses. More in particular, the interface device according to the invention permits achieving, inside each condominium apartment, all video door entry and home automation functions, which up to now could have only been implemented in single buildings.
Currently, intercom and video entry door systems permit the communication of a certain number of users, situated inside housing units, with one or more external calling stations.
The need to arrange an increasingly growing number of accessory functions and home automation applications, to be used in such systems and inside each housing unit, such as for example the audio call with secret conversation, the recording of images taken by the video entry door telecamera, the management of intercommunicating appliances or stair light lighting devices or electronic or electromechanical actuation devices, remote video-control, and the comfort and energy management, cause substantial problems with regard to the high number of electric cables to be installed. Such problems exponentially increase, with
respect to the number of required functions, the consequent costs and the need to employ specialised personnel to carry out the expected connections. In the specific case of condominiums, moreover, such systems must also permit carrying out renovations of the single housing units in a simple and fast manner, without having to change the common wiring parts of the video door entry installation. The new generation home automation systems must in addition be capable of communicating with the outside world, so to be able to interact with the building from fixed line and mobile telephones and/or from any PC, via local network or Internet, in order to prearrange the house for the desired reception, for example for activating the heating or turning on the washing machine, restoring electricity, turning on several light fixtures, opening a specific number of motorised rolling shutters, adjusting the ambient temperature in the rooms, etc. All this excessively increases the building wiring, which must above all allow for prearranging all the normal telephone functions, in addition to the communication functions between the telephone and the external video door entry station, activation of electric locks, stair lights or any other electric and/or electronic actuator. One object of the present invention is therefore that
of making an interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses, which permits making the video door entry system interact with a two-wire video door entry system, making possible the bidirectional audio and monodirectional video connection from the condominium cable duct of the analogue and/or digital video door entry installation of the building to the two-wire installation of every single condominium apartment.
Another object of the present invention is that of making an interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses that permits making, inside the apartment, a dedicated video door entry installation with independent internal phone station, adapted to communicate inside the home without occupying the condominium cable duct. Another object of the invention is that of making an interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses that permits making home video-control inside the apartment, by installing local telecameras and dedicated external stations, and the control of home automation functions, such as alarms, thermoregulation, sound diffusion, lights automation, etc.
Another object of the invention is that of making an interface system for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses that permits isolating the home automation installation from the common installation, permitting the carrying out of renovations of home units without substituting the common parts of the condominium video door entry installation. A further object of the present invention is that of making an interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses that results highly reliable and with relatively limited costs, with respect to the prior art, given the same executable functions. These objects, according to the present invention, are achieved by making an interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses, according to the attached claim 1; other technical detail characteristics are present in the subsequent claims .
Advantageously, the interface according to the invention is connected on the condominium cable duct of analogue and/or digital video door entry systems like a common internal station, so that inside each apartment it is possible to make a dedicated video door entry system, with independent sound intercom, that permits
communicating inside the home without occupying the cable duct.
It is moreover possible to make the home video-control system by installing local telecameras and dedicated external stations (for example, on the landing) .
The installation can finally be enhanced by being able to control all home automation functions can be controlled, such as alarms, thermoregulation, sound diffusion, automation and/or lights, by always employing only two non-polarised wires for the entire system, so as to obtain wiring speeds, both for new installations and in renovations, as well as ease and safety, since it is possible to pre-wire the entire system and install external and internal stations afterward, after the work has been completed.
The two-wire wiring is in fact simple and fast and is used for wiring the entire system, eliminating the risk of errors and device damage. Further characteristics and advantages of an interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses, according to the present invention, will be clearer from the following description, related to an exemplifying and non-limiting embodiment of the interface according to the invention, and referred to the attached drawings, wherein:
- Figure 1 is a front schematic view of the
interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses, according to the present invention; - Figure 2 is an approximate block diagram of the interface device functionality, according to the invention, employed between an analogue video door entry system and a two-wire multimedia bus;
- Figure 3 shows a possible circuit connection mode of the interface device according to the present invention.
With particular reference to the abovementioned figures 1 and 2, the interface device DF, according to the invention, made of DIN modules, permits interfacing the analogue/digital video door entry systems - employing external stations PE, connected to a condominium cable duct MN, with telecameras T, loudspeakers A and microphones M - with a two-wire multimedia bus BS, employing at least one video modulator MV, at least one sound section SF and/or at least one actuator AT.
In such a manner, the interface DF makes possible the bidirectional audio and monodirectional video connection from the condominium cable duct MN of a condominium or residential building to each apartment APP of the condominium or building, isolating, by means of the galvanic isolation IS present inside the interface DF, the home automation system present inside
the apartment APP from the common video door entry system belonging to the condominium cable duct MN. In particular, the interface device DF permits coupling the two-wire multimedia buses with the digital video door entry systems and with the analogue video door entry systems, with or without an exchange. The interface device DF, object of the invention, has an analogue side comprising a connector LA, for example of 12 -way screw type, a two-way connector INTl for the connection of the non-polarised two-wire multimedia SCS bus BS, a video adjuster or trimmer RVl, a receiving audio adjuster or trimmer RV2 , a transmitting audio adjuster or trimmer RV3, an LED Ll, adapted to signal the status of the device, and a series of configuration seats of a configurator SS, which permits selecting the type of system to which the device DF must be interfaced.
Alternatively to the connector INTl for the bus BS connection, it is possible to wire the device with "patch cord" (pre-wiring) , using the suitable seat INT2 provided at the front of the interface DF. The bus BS is a non-polarised two-wire bus and the two wires of the bus BS support the device power supply, the baseband sound signal, the stereophonic signal of a sound diffusion system and the modulated video signal of the two-wire video door entry system. In addition, the LED Ll signals the status of the
interface device DF with a different flashing, depending on whether the system is at rest, if a conversation is underway between the apartment APP and the cable duct MN or if a conversation is underway inside the apartment APP.
For the interface device DF, the configuration is also provided for by means of the configurator SS, as a function of the system with which it must be interfaced. For example, in figure 3, a typical circuit configuration is shown, in which the interface device DF permits the coupling between an N-wire analogue system equipped with level shunt CG positioned on the cable duct MN, external station PE, power supply AL and internal stations Pl, P2 and P3 , and an apartment APP, equipped with internal stations MT, connected with an audio/video node NAV, that permits its wiring by means of non-polarised two-wire multimedia bus cables BS. In the apartment APP, the two-wire installation can provide for all system functionalities, since internal station and external station monitors MT and/or private telecameras PL can be installed; moreover, intercommunicating calls can be carried out in apartment APP with independent sound, two-wire sound diffusion devices can be installed and/or be interfaced with other possibly present home automation systems, such as antitheft systems, thermoregulation systems and
light or motor automation systems, etc.
From the standpoint of the apartment APP, the two-wire video door entry installation is analogous to a single family installation, and in particular takes on the internal configuration at an apartment interface.
The call from the public external station PE of the analogue or digital system connected with the condominium cable duct MN is switched in the apartment APP into General Broadcasting mode, by means of the microcontroller MC of the interface DF (fig. 2) .
Thus, the same situation is obtained inside that is found in a single-family installation, since all internal stations ring, but only the (predetermined) main station is lit up. The possible local external stations PL are configured starting with 1, while the common parts are reachable at the address 0 of the external stations PE. In this manner, by configuring 0 on the internal stations MT at the apartment APP, it is possible to make auto- ignitions and/or cyclings (if provided by the system) on the common external stations PE, according to analogue system rules .
In general it is not possible to access the common external stations PE in a directed manner, since they are indistinguishable both in analogue systems and in 8 -wire digital systems (in this case they are only distinguishable downstream of the level shunt CG and
thus not by the internal stations Pl, P2 , P3) .
From the description • carried out, the characteristics of the interface device for communicating between analogue and/or digital video door entry systems and two-wire multimedia buses, which is the object of the present invention, are clear, as its advantages are clear.
In particular, the advantages regard the following aspects : - possibility to make a two-wire bus system interact with a video door entry system of a residential building of analogue and/or digital type, so to achieve inside each apartment all video door entry functions, home video-control and home automation functions, such as the management of alarms, thermoregulation, sound diffusion, light and motor automation, etc.;
- possibly to send commands and/or signals between the two-wire bus system and the video door entry system of the residential building;
- possibility to galvanically and functionally isolate the home automation installation from the common video door entry installation, so to permit complete renovations of the various housing units without having to substitute the common parts of the video door entry installation;
- reduction of the overall cost of the wiring
operation, with respect to the prior art;
- possibility to employ relatively little- specialised personnel, due to the fact that the installation operations are substantially facilitated with respect to the prior art;
- no use of electronic control units and consequent absence of actual electronic programming states, and thus consequent decrease of possible failures, programming errors and/or malfunctions of the entire installation;
- relatively limited overall cost of the used components, maintenance and employed workforce with respect to traditional connection systems, given the same executable accessory functions and by virtue of the attained advantages.
Finally, it is clear that numerous variants can be made to the interface device in question, without departing from the novelty principles inherent in the inventive idea, as it is clear that, in the practical actuation of the invention, the materials, shapes and sizes of the illustrated details can be of any type depending on requirements and the same can be substituted with other technically equivalent elements.
