Explanation of the invention.

Thus, and concretely, the invention consists in a composite intercom and access control system by various devices, which are connected each other using corresponding connection cables (replaceable  optionally by wireless systems), comprising essentially: a MODEM-GSM equipped with a SIM card, a PLC, a fixed telephone terminal, a tone decoder, a communications panel and a communications terminal for each resident.

The communications panel will be located at each of the entrances to the enclosure, and incorporates a keyboard number intended to be able to enter the residence number to which you want to access, a speaker and a microphone.

Said communications panel is located properly connected to a PLC and a fixed telephone terminal provided with a numerical rosette, said PLC being the basic unit of the whole system, to which the other elements are connected, formed by a GSM-RTC MODEM, a numeric keypad alternative, in case the resident wants to access the enclosure and do not have your telephone terminal, a decoder of tones and the corresponding motorized doors.

In this way, the invention manages the Voice communication between two users, one who wishes to access the enclosure and another that, being already in it, has the control of access, with the possibility of accessing the enclosure, by residents themselves or people authorized, by inserting a code on a keyboard numeric housed in access doors, together or in a way  independent of the communication panel.

Furthermore, the invention advantageously allows that Any user can access the site if they have a communications terminal (a mobile phone) whose number is is registered in the PLC database.

The intercom system and control of programmable telephone access therefore represents a innovative structure of structural features and constitutives unknown so far for that purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is attached herein descriptive, as an integral part of it, of a game of planes, in which with an illustrative and non-limiting nature, represented the following:

Figure number 1.- Shows a diagram of blocks in which the main ones are shown schematically elements that comprise the intercom and control system programmable telephone access according to the invention as well as the arrangement and connection between them.

Preferred Embodiment of the Invention

In view of the aforementioned figure 1 and only, and according to the numbering adopted therein, a preferred embodiment of the system comprising the parts indicated and described in detail below.

Thus, and according to the numerical references indicated in said figure 1, the system in question is essentially constituted from a communications panel (1) located at each of the entrances to the enclosure, which incorporates a numeric keypad (2) designed to enter the number of residence you wish to access, a speaker (3) and a microphone  (4).

Said communications panel (1) is located properly connected to a PLC (5) and a telephone terminal fixed (6) provided with numerical rosette (7), said PLC (5) being the basic unit of the entire system, to which a MODEM is connected GSM-RTC (8) equipped with a SIM card, a keyboard alternative number (9), in the case that the resident wants access the premises and do not have your telephone terminal, a tone decoder (10), and the corresponding doors motorized (not shown).

On the other hand, each resident has a communications terminal (11) whose number will be found conveniently registered in the PLC database (5), by which the drive of the mentioned ones is controlled doors, allowing both access to third parties from the inside of each residence, such as access from outside to one's own user, as long as you carry it with you.

Thus, the operation of the system Intercom and programmable telephone access control according to The invention is produced as follows:

The operation begins with the introduction in the keypad (2) of the communication panel (1) of the residence number to which you want to access. The signal from the communications panel (1) it reaches the PLC (5), which identifies it and associates it with a number of phone that is previously loaded in your database, and that  corresponds to the resident's communications terminal (11) correspondent.

Next, the PLC (5) makes the call to said number through the fixed terminal (6) and enables telephone communication between the communications terminal (11) the resident and communication panel (1), through the speaker (3) and of the microphone (4) that it has, as it has been mentioned.

If the resident decides to order the drive of the door, it will mark a numerical key previously programmed in the PLC (5), whose tones will be received by the decoder of tones (10) and will be sent to the PLC itself (5), which will manage the activation of the relevant mechanisms that allow door opening.

The PLC (5) is capable of receiving the signal from a such number of communication panels (1) as access doors to the enclosure exist, and establishes the connection to a number of terminals of communications (11) as registered users.

Once the connection between a panel of communication (1) and a communication terminal (11) and established voice communication, the PLC (5) discriminates the rest of requests for entry from that same door, since for each door Only one voice communication will be possible.

On the other hand, if the resident is outside the residential complex, and carries with it the terminal of communications (11), you must dial a specific telephone number to contact the GSM-RTC MODEM (8), which as It has been said that it has a SIM card.

The PLC (5) verifies that the terminal number of communications (11) of the caller is registered in his base of data, and if it is, it activates the opening of the door.

Otherwise it does nothing, since the PLC (5) identifies incoming calls and only considers authorized the terminal numbers of residents who have previously been entered in your database.

If the resident is outside the complex residential but does not have its communications terminal (11), or having the same service restricted Caller ID, you can access the site by entering a second numeric key, previously inserted in the base of PLC data (5), through the alternative keyboard (9), housed in the outside of the enclosure, and that transmits the data to the PLC (5).

The PLC (5) recognizes this key and, where appropriate, will order the opening of the door.
