Abstract

The proposed wire-and-wireless communication system can be used for data communication when using a power transmission line as a communication line.

Description

Description of the invention

The utility model relates to communication systems and can be used to exchange information via power lines 2.

Various variants of information transmission systems through power lines are known, which are used to organize an element of the Internet access network, to build local computer networks, as well as to build information networks for combining household electronics with the possibility of centralized control. The advantage of this technology is the prevalence of electrical networks, the absence of additional costs 70 for the construction of communication lines, reliability due to the physical strength of power transmission lines, the type of used modulation |11.

When data is transmitted over power lines, OBYOM modulation is used, in which the signal is divided into many streams with a lower speed, which are then transmitted simultaneously at several different frequencies (subcarriers), which are orthogonal, which makes it possible to demodulate modulated oscillations even in conditions of 79 partial overlapping of bands individual carriers. In addition, frequency-selective attenuation of the propagation medium or narrowband interference in the channel blocks only some carriers, not the entire signal, which can be easily corrected by the carrier selection algorithm. The main advantages of OBOM modulation are the reduction of the amount of crosstalk during transmission and the provision of high resistance to intersymbol interference (21.

The closest to the claimed useful model, in technical terms, is a local area network built on power lines, consisting of an electric bus, on which power is supplied to devices and data transmission within the network, devices for protection against current and voltage surges, and network filters . Electrical devices are connected to the network through plug sockets, through which data exchange is carried out between them and the local network.

However, in a number of cases when it is not possible to exchange information from power lines with some device, it is suggested to partially transmit data directly over electric wires, and where this is not possible, to exchange information wirelessly between the local network and this device. At the same time, the electric wires will act as a receiving and transmitting antenna, for the signal amplification of which special transceivers will be used. at

The useful model is based on the task of expanding the coverage area of the local network, organized along power lines, by organizing a wired-wireless communication system.

The task is solved by the fact that in the communication system, which includes electric wires, which are used as a bus for data transmission, electric sockets for connecting routers and ipe adapters, according to which devices (for example, computers computers, printers, scanners, household appliances, etc.) are included in the 325 common bus, an adaptive filter is introduced, and which are included directly in the data bus in areas where there is a high level of interference or where a useful signal is emitted, regenerators are included Through electrical outlets in areas where the signal experiences the strongest attenuation, and wireless adapters connected to the corresponding devices with which a wireless connection is established. "

In comparison with the prototype in the proposed technical solution, what is new is that adaptive filters have been introduced, C 70 which, in addition to increasing the interference immunity of the transmitted signal due to blocking, which will raise the BOTH of the modulated signal, which experience strong attenuation due to the properties of the environment or the presence of narrow-band interference, analyze guidance created by other emitters operating in the same frequency range and exclude subcarriers with corresponding frequencies, thereby increasing the electromagnetic compatibility of the entire system as a whole; wireless adapters for organizing reception and transmission of the signal emitted by electrical wires, as well as regenerators for amplification and retransmission of the received signal directly in the local network itself. (se) Where the property of the proposed wired-wireless communication system is new, because in the prototype only wired communication or communication through an optical interface is assumed between the devices. Due to this, the coverage area of this network is limited to the area where the wires are located. Application of adaptive filters for av! 20 filtering of the ORGOM-modulated signal, wireless adapters for connecting devices to the network and regenerators for amplifying and retransmitting the received signal directly in the local network itself allows to expand the coverage area of the local network organized by power supply lines.

The diagram shows the scheme of the proposed wired-wireless communication system. (see Fig. 1, Fig. 2).

Wired-wireless communication system consists of electric wires 1, used as a bus for 52 data transmission, electric sockets 2 for connecting Roucheg and ipe adapters C, with the help of which devices 4 s (for example, computers, printers, scanners, household equipment, etc.) included in the common bus, adaptive filters 5, which are included directly in the data bus in areas where there is a high level of interference or where a useful signal is emitted, regenerators b, included through electrical sockets in areas where the signal is tested the strongest attenuation, and wireless adapters 7, which are connected to the respective devices with which wireless communication is established.

The proposed wired-wireless communication system works as follows.

Information exchange between devices is carried out over electrical wires using Roughegg technology

Mpe. In those cases when the access of electrical wires to any device is difficult or there is a transformer between the considered local network and the device, which does not allow to organize a wired connection, the useful signal, passing through adaptive filters, which cut out from its spectrum what will raise, that experience a strong attenuation due to the influence of interference in the wires, due to the frequent non-selective properties of the wires themselves, due to the guidance created by other emitters operating in the same frequency range, is transmitted due to the radiation created by the electric wires when transmitting data along them. The emitted signal is received by the wireless adapter, processed by it and sent directly to the input of the device.

Due to the fact that, in addition to the obstacles existing in the wires themselves, adaptive filters analyze the guidance created by other emitters operating in the same frequency range as the wired-wireless communication system, and cut out what will be transmitted, matching the guidance frequencies, it is possible to ensure electromagnetic compatibility with other communication systems.

Taking into account the principle of reciprocity, electric wires can also act as a receiving antenna. In this case, the signal from the device is transmitted through the adapter and received by the wires, which in this case act as a receiving antenna. Regenerators are used to amplify the received signal, which then transmit it to other devices in the network.
