Problems solved by technology

[0005] On the other hand, existing communication networks for residential and custodial environments, offices, etc. are designed to integrate two or more services, such as telephony services, cable broadcast music, data transmission, etc., so that their designs are usually Tailor-made for this purpose, which means expensive and difficult to modify and / or update if new services or network expansion are required

Embodiment Construction

[0031] According to the accompanying drawings, it can be seen that the communication system of the present invention contains a plurality of different modules (1), (1 '), (1 n )..., these modules are connected to each other by two buses, the read bus and the write bus. These buses are connected to each other by means of a differential transmission system, which produces greater immunity to noise, thereby reducing the power required for this transmission, and at the same time reducing the level of electromagnetic radiation.

[0032] The read-out bus (2) and the write-in bus (3) synthesize a single UTP data transmission cable (4), which includes four unshielded twisted pairs, and only needs to set up the read-out bus ( 2) and write to the bus (3), so that different connection configurations can be formed between the modules, which will be explained later in this specification.

[0033] In any case, the first terminal (1) of the network is configured in an open-loop arrangement ...

Abstract

The system is based on the arrangement of a plurality of terminals (1), (1')...(1 n ), which are interconnected with one another to form a digital network by means of two databuses, one write and one read, by means of differential transmission, with a hybrid connection topology based inter alia on UTP-type cables (4). Each terminal is constituted by a DLP-type card (7), which contains a programmable logic device for the management of a series of cards associated with the card (7), said cards being a main card (8) and a user-interface card (9), which enable the user to configure the various system options, it being possible, also, to incorporate one or more extension cards (11-11') for the input and output of audio / video signals, the Internet, a telephone line or an automatic-door-entry line, and also a remote-control and alarm card (10) for activating external loads, activating alarms and receiving signals originating from sensors.

Description

[technical field] [0001] The present invention relates to a digital communication system specially designed to replace signal distribution systems in homes, custodial environments, offices, etc., the purpose of which is to avoid the need to assemble different voice, video, door intercom, Internet, cable broadcast music and Alerts operational networks, including heating and air conditioning systems and activation of different electrical equipment. [0002] The object of the present invention is to provide a multifunctional system that can replace the above-mentioned networks and combine them in a single network, which is simple, reliable, easy to retrofit, recyclable, inexpensive to implement and easy to install. [Background technique] [0003] At present, the communication network has been widely used, and we can divide the communication network into two main categories: branch network and ring network. [0004] However, while a ring network can maintain network functionali...
