Description

Mobile network repeater with inductive power supply

Field of technology

The present invention relates to a mobile network repeater with inductive power for building and expanding mobile networks.

Current state of the art

Currently, repeaters with autonomous or stationary power sources are used to build and expand wireless networks, which requires complex installation and preliminary preparation of the installation site. However, there are situations where it is not possible to extend the mobile network due to difficult accessibility of the site or terrain.

In the file US 2007109088, the principle of inductive consumption of electrical energy is described with the help of magnetic induction coils at the point of creation of a magnetic field between two conductors. The solution is primarily focused on the arrangement of components in the housing of the communication device.

In the file US 2003234713, a coupling device for mounting on a conductor of a high voltage network is described. The housing, in which the electronic circuits are stored, consists of two longitudinal parts. In each of the two parts, half of the detachable toroidal core of the induction coils for powering the electronic circuits of the coupling device is stored.

Both mentioned devices have the following disadvantage. When mounting the device on the electrical network conductor, it is necessary to at least partially dismantle the device case. There is a risk of damage to the components stored in the device case during subsequent assembly on the wire.

US 2016149635 describes a repeater for a wireless Wi-Fi network. The repeater includes a microprocessor that is configured by control information to convert data packets from 5 GHz to 2.4 GHz and from 2.4 GHz to 5 GHz as needed.

The essence of the invention

The above-mentioned shortcomings are largely eliminated by a mobile network repeater with inductive power supply containing induction coils for extracting electrical energy from the conductor, an AC/DC converter for powering the repeater electronics, a receiver/transmitter, a first communication antenna and a second communication antenna for two-way information transmission and configuration module for setting the operating parameters of the repeater, according to the present invention.

The first communication antenna is for the upward direction and the second communication antenna is for the downward direction. The configuration module is connected to the monitoring center via the configuration channel.

This repeater is arranged in an elongated housing having a first end portion and an opposite second end portion. Each of the two end parts comprising the split-head inductor is made in part as a surface provided with a depression for placement on a mains conductor. An opposite handle fitted with an opposite surface with a recess rests on this surface. This is how a detachable handle is created for connection to the electrical network conductor.

The repeater components AC\DC converter, receiver/transmitter, first communication antenna, second communication antenna and configuration module are provided with covering even during mounting of the repeater on the wire.

In this design of the inductively powered mobile network repeater, the power for operation is taken directly from the high voltage electrical wires. The repeater can be configured remotely using signals transmitted through the configuration channel. Here, the configuration channel is understood as a wireless communication channel or the use of communication over a high-voltage electric wire.

The task was to build a mobile network repeater, which is powered from a high-voltage line using an induction coil with the possibility of quick configuration via the configuration channel.

The proposed repeater enables the expansion of wireless networks mainly in areas with difficult access or time-limited deployment.

Clarification of drawings

The mobile network repeater with inductive power according to the present invention is described in detail on a specific example of implementation with the help of the attached drawings, where Fig. 1 shows the overall appearance of the mobile network repeater with inductive power and its placement on two or one high-voltage conductor. Fig. 2 shows a block diagram of the internal wiring of a mobile network repeater with inductive power supply.

Examples of implementation of the invention

Conductor 1 is part of a high-voltage power line. The repeater is mounted on the high-voltage electrical conductor 1 so that the induction coil 2 is wrapped around the conductor 1. The induction coil 2 has a split head that allows the repeater to be mounted directly on the conductor 1.

The voltage induced in the coil 2 is fed to the AC/DC converter 3, which is the power source for the remaining modules, i.e. the receiver/transmitter 4 and the configuration module 8.

Receiver/transmitter 4 serves as a signal amplifier for both directions of communication, up and down. Transmission and reception of signals are provided by the first communication antenna 5 for the upward direction and the second communication antenna 6 for the downward direction.

Access point 7 is a point that creates a wireless network or signal in the vicinity of the repeater. The wireless network created in this way is used to connect and communicate among network participants. If it is an access point 7 with a signal, it can be used as a radio beacon or navigation point.

Configuration module 8 ensures the setting of the entire mobile network repeater with inductive power supply.

The monitoring center 9 communicates with the configuration module 8 using the configuration channel 10. This principle allows the configuration settings of the repeater to be determined and at the same time to be changed according to requirements.

The repeater is installed on two adjacent conductors of 1 high-voltage lines instead of a standard safety bridge. If it is a very high voltage line, for example over 200 kV, where this jumper can affect the operation of the line, e.g. a breakdown through the repeater housing, then it is possible to install the repeater on one wire 1.

It is assumed that multiple repeaters will be installed on the line at certain intervals. This creates a basic communication channel up and down. The repeater communicates with the access point of the mobile network. This can be an access point of a Wi-Fi network according to the IEEE 802.11 standard or other standards. The cell created in this way will enable communication with a classic Wi-Fi device.

By deploying multiple repeaters, the coverage of wireless networks near high-voltage power lines is extended without the use of stationary repeaters with autonomous power sources.

A typical use of an inductively powered cellular network repeater can be seen in the following applications.

As a repeater of a wireless network, where the repeater will only act as a wireless signal amplifier. In this case, it will be appropriate to use directional antennas, which will ensure two-way communication.

As a terminal access point of a wireless network (AP - access point), the repeater will serve as an access point of a wireless network according to IEEE 802.11 standards or other standards. In this case, it will be appropriate to use a directional antenna for upward communication and an omnidirectional antenna for downward communication.

As a radio beacon, in this case it will be appropriate to install a narrowly directional antenna, where the beacon will clearly define the direction.

Industrial applicability

The invention finds application in all areas of communications. Especially in the case of a short-term need to build a communication network in areas with poor infrastructure.
