The SCOPE of the INVENTION

The present invention relates to a digital communication system, specially designed to replace the distribution of signals in the residential, social, administrative and similar buildings to avoid installation of different networks, voice traffic, video, intercom, Internet, transmitted over the radio music and alarm systems, including systems control of heating and air conditioning and activating different electrical devices.

The aim of the present invention is to provide a universal system that replaces the above-mentioned network, grouping them into a single network, and this system should be simple, robust, adaptable, reusable with minimal implementation costs and is very easy to install.

BACKGROUND of the INVENTION

The use of communication networks is currently widespread, and we can split them into two main types: branch and a ring-shaped network.

It should be noted that although the ring-shaped network and retain the functionality of the network between terminals in the case of a connection failure, this type of topology is typically more complex than the network of the branch type, because most of this topology, which requires a closed communication between all terminals forming the network.

On the other hand, the current communication network, and is used in residential, social, administrative and similar buildings are designed to join two or more services, such as voice traffic, music, transmitted by radio, data transmission, etc. and their design is usually designed specifically for these purposes, and this means that they are expensive, they are difficult to modify and/or update, if necessary, new services or expansion of the network.

Description of the INVENTION

The proposed communication system for residential buildings, office buildings and similar places provides a fully satisfactory solution to the aforementioned problems while using one installation of internal and external traffic speech, music, transmitted by radio, an alarm system and temperature sensors to control heating and air conditioning in each terminal, including remote control of various devices associated with the terminal, and transmitting video signals, and the optional message is encrypted, and the optional use of the compression procedure for information.

In particular, the proposed system is based on a scheme with multiple terminals, which terminals are connected to the digital education network with two data bus - bus read and bus write - through differential data transmission system with a hybrid that is ologia connection combining Duhring and ring topology.

The first terminal when the ring is open, should create empty frames, which are then transferred by bus write, and while passing through the bus records, including the first terminal, these frames are filled with the terminal. When the frame passes all bus write and reaches the terminal end of the network, this latter terminal is automatically configured in a closed loop, and the output record bus is connected with the input bus read. This is the point at which to start the bus reading frames and then pass through the terminal, which reads the necessary information from these frames, thus providing communication between the different terminals.

Each terminal can update certain fields in frames transmitted by the bus records, and, in addition, can read any of the fields to frames transmitted by the bus reading.

When the footage again reach the open end of the first terminal (or terminal responsible for the creation of these frames), frames are lost.

This is a very robust configuration, as in the case of denial of any connection of two networks, acting separately, will be automatically set to continue, providing data transfer between different terminals participating in the specified process. The terminal, not on uchumi footage from the record bus, will be automatically configured as a first terminal, creating empty frames, and the terminal is not receiving frames from the bus reading, connect its output bus to the input bus read, automatically configuring itself as the last terminal in the topology.

Due to the use of differential signaling bus read and write consist of a single pair of cables. This type of signaling reduces the power required for transmission, at the expense of increasing the noise immunity while reducing the radiation level of the transaction.

Each terminal connected to another terminal to the next or previous cable with unshielded twisted pair, which contains four cables with twisted pairs. One pair is used to record bus, the other bus reads and two twisted pairs remain free to extend the capabilities of the system, such as access to the Internet, video inputs/outputs of any of these terminals, as well as paralleling network connections, simplifying its structure to reduce the cost. In addition to the cable with unshielded twisted pair can be used Quadrifilar telephone cable. In addition, the system can be configured for time division multiplex buses read and write, and to connect terminal requires only one twisted pair. Inthis case, the connection terminals can also be used bifilar telephone cable. Finally, the terminal can be connected by optical fiber made of plastic or glass, wireless or electrical network, with the regulation of the services available to the bandwidth of the connection procedures between the terminals in each case.

Frames transmitted on the specified bus read and write, is structured in the following way: they are divided into the header control field and different transmission channels for music, speech, images and data, depending on the bandwidth of the used cable. Control field consists of the information transmitting equipment and corresponding control information, including the type of the control message, the receiver and the status of any existing alarm device.

When the detection terminal of its identification number in the appropriate frame he knows that the control field of the frame allocated to it, and that he should fill this field with the appropriate information.

As already mentioned, the implementation of a system based on a modular principle, so that all functions can be obtained by connecting to the base terminal of additional cards. Each base terminal comprises a card PLD (programmable logic device), which includes a programmable logic device, main and interface cards. If you want the tees to more music and/or video channels can connect add-in card; in addition, you may connect card remote control and alarm systems, if the system requires these functions.

Map PLD includes a programmable logic device, designed to control and monitor the work of all other cards in a few appropriate connectors that enable you to program the card through a connecting port of a personal computer or the card storage device.

The main map is intended to provide basic functionality any type of network, with the ability to maintain the channel of the transmitted music while listening to another channel, to meet the requirements of voice communication, to read temperature and to perform the functions calendar/clock. For these purposes, the card has two AC and CA audio Converter, designed for analog-to-digital and digital-to-analog conversion channel music and speech, as well as analog circuits for processing these signals. In addition, this map contains access schemes and connectors designed to connect the above mentioned modules.

In addition, the main card has two integrated circuits used for issuing hourly/calendar information, as well as information about room temperature terminal which includes a battery with a charging system in which avoid loss of hourly information.

Map user interface can be used to configure different options of the device using the menu system, which the user can browse for the configuration of different music channels and channels of images, transmitting or receiving information, ongoing challenges, while managing sensors and alarm, remote control, calendar and temperature conditions. This card has a display and keypad, as well as several piezoelectric buzzers, inform the user of various conditions.

Optionally, the card can contain RF and/or infrared transmitter/receiver for transmitting control data over a specified network, and the device required for establishing voice communication directly through the terminal. This function can be performed when connecting to map the user's regular telephone terminal.

In addition, the module can be supplemented with one or more cards for the expansion of various AC and CA converters such as AC and CA converters the main map, and the corresponding cascade audio adaptation to increasing the number of channels transmitted music. In addition, in the specified map expansion or a separate map with their respective cascades adaptation may have several p is OBRAZOVATEL to provide input and output different video channels, the phone line connection to the Internet or line of intercom.

This structure may be supplemented card remote control and alarm systems that will be used to connect different sensors alarm (such as fire, burglar or sensors flooded with signals from sensors connected to the specified map, providing remote control or activate multiple devices using a relay associated with this map.

Messages transmitted over the network, you can optionally encrypt and shrink depending on the program of the programmable logic device.

Thus, the modular communication system, the modules which can be connected to combine multiple functions at lower cost, and which can easily be scaled using the above expansion cards.

When frames are on the bus records (3), they are terminals or modules(1), (1'), (1"), and after the frame has passed the bus account and filled out by each terminal, he reaches the terminal end of the network (1ⁿ), where the ring closes and the specified terminal (1ⁿ) is designed so that the output record bus (3) is connected to the input bus read (2). After this point shots will pass through different terminals, which will read the necessary information from these frames, providing a link between terminals. Each terminal can update certain fields in the frames passing through the bus entry. Once the frame reaches the open end of the topology, i.e. the first terminal (1), responsible for the creation of this frame, it will be lost.
