Abstract

Installation of intercom with bidirectional access to telephone line, of the type of facilities that comprise a series of intercom panels that are distributed by the accesses to the house, and that each controls its respective lock, connected to an indoor telephone, whose intercom panels incorporate telephone circuits and connect to a control module that incorporates a DTMF circuit connecting to the telephone line to establish two-way communications through said line with a programmed telephone number. The control module incorporates a call retention and forwarding circuit. The control module is connected to the domestic telephone system. The control module incorporates an output that can be connected to an intrusion detector to establish a two-way telephone communication with the programmed number in case of intrusion.

Description

Installation of intercom with access bidirectional telephone line.

Object of the invention

The present invention relates to a intercom installation with bidirectional line access telephone, through any dialing telephone multifrequency, allowing communication and / or opening from the door from any of them with the doorman plate corresponding bidirectionally, and enabling switching between different established communications.

Background of the invention

Currently the facilities lines intercom and the conventional telephone line are separatives, that is, they are not interconnected, which makes impossible to establish direct communications from the terminals of the intercom's street with the inhabitant of the house if this one is absent, and therefore they make it impossible to answer calls made on the street signs if the tenant is missing in the house

Description of the invention

The installation of the invention enables the bidirectional and switched communication between different terminals or intercom doorplates and a local telephone (from own address) or remote through the telephone line as well how to activate the door opening from any of them, incorporating, in addition, the call waiting features, consultation, transfer, telephone line retention, diversion External door phone call and intruder detection.

According to the invention, the installation comprises a series of intercom panels, distributed for access to housing, each of which controlling the corresponding lock.

The plates are connected to a control module based on programmable logic and connectable to the telephone line conventional by means of a DTMF marker circuit. This device connects directly to the network termination point of the telephone line, and the other telephones of the installation Domestic are then connected to the control module. He control module also incorporates a retention circuit of line and diversion, which allows, through control DTMF, Switch between the different communications established between Different doorman plates and the telephone line.

The goalie plates incorporate two complete telephone circuits that allow establishing a Telephone communication through the control module.

The control module incorporates a connection for a motion detector, which allows to detect intrusions. In In this case, the dialer circuit makes a phone call to a programmed number, establishing two-way communication to through a microphone and headset that incorporates the module control.

The control module also has a additional output capable of operating an electric lock, directly, and independently of those governed by the plates Goalkeeper

In the case of community housing, the license plate community doorman feeds through an external source, and control the communication between her and the different neighbors, inhibiting any other communication if there is already an established one, and not enabling other communications until free state. In addition, it incorporates a voice detector circuit for, if due to a bad use or operation a communication is blocking the equipment, deactivate the block deactivating the cause (after a good hung will be operational again) and allowing operation the rest.

All communication between the control module and the goalie plates are made only by two wires, switching the control module, using relays preferably, between the different operating voltages of each state.

The installation of the invention is also similar to video intercom installations, incorporating in this case two additional wires for the transmission of the signal of video.

Brief description of the drawings

Figure 1 shows an installation scheme of the invention.

Figure 2 shows a variant embodiment of the installation of the invention.

Description of a practical embodiment of the invention

The installation 1 of the invention comprises two 2 intercom panels distributed by the access to the housing, each of which controls the corresponding lock 3, and incorporates the call button and microphone and Communication speaker, not represented.

The plates 2 are connected to a module 4 of control that is inserted in series in the telephone connection domestic, just after the network termination point (PTR) 5, and before referrals of telephone terminals 6 domestic

In a variant embodiment of the invention for single-family homes that is reflected in figure 1, the module 4 has an output 7 capable of operating a third lock electric 8 independent of those controlled by the plates 2.

In community facilities, as seen in the Figure 2, one of the plates 2 is communal, feeds on a external source 9, and is responsible for switching voltages to the module 4, controlling their status, establishing Communications with the different neighbors. Established one communication, the possibility of communication of the other neighbors until a preset time of Inactivity of established communication (prevents misuse by part of some neighbor that could block the rest), which detects by means of a voice detector 9a that incorporates its own community board.

Module 4 also connects to a detector of optional movement 10, which allows to detect intrusions. He module incorporates a DTMF 11 circuit for connection to the line telephone, and a circuit 12 of line retention and diversion to switch, through control tones, between the different established communications.

Both goalkeeper plates 2 also incorporate two complete telephone circuits 2a to establish the direct communication with the telephone line through the module Four.

The operation is as follows: making a called from any of the goalkeeper plates, it can be attended by the inhabitant of the house, if found present, through module 4 or domestic terminals 6, being able to also control through these elements the opening of the corresponding door, or directly from the Module 4 the third lock.

In case of absence, you can schedule a telephone number in module 4 and a divert command from call. In this case, a call from any of the plates 2, after a certain timing, it will make module 4 make a call to the programmed phone number, setting a two-way communication, and allowing the tenant, absent of housing, talk to your interlocutor, and even activate the locks

Likewise, and by means of a switch, not shown, of module 4, and after a certain timing, it will cause module 4, and in case of any intrusion picked up by detector 10, to establish a telephone call with the programmed telephone number, so that the Absent user will be able to speak with the interior of the house through a hands-free circuit, not represented, with a headset and microphone, which incorporates the module
Four.

Connection 13 of module 4 with plates 2 is performs using 2 wires, switching module 4 the different operating voltages
