Description

Network for electrical energy and computer data transport.

The present invention relates to a network for electrical energy and computer data transport.

More specifically, the invention is intended for transporting electrical energy and computer data in one integrated and cooperating network.

It is known that fossil fuels as an energy source are increasingly being replaced by renewable energy sources such as wind energy and solar energy, from which green electrical energy is drawn.

The transport of this green energy is traditionally done via an alternating voltage network. However, the traditional alternating voltage network is overloaded by, for example, more distributed energy generation by solar panels and wind turbines and an increasing storage in batteries of electric cars, for example.

The traditional alternating-voltage network is a legacy from the past and is threatened by the rise of semiconductors and DC devices. Every device with a logical chip on board operates on direct current. Various sensors, LED lighting, ventilation, IT, multimedia, television sets, but also household appliances including white goods and heat pumps require direct current.

BE2018 / 5133

Currently, the first step in these devices is an inverter that converts AC voltage to DC voltage.

Distributed electrical energy generation also requires the conversion of direct current from solar panels, for example, to alternating current in order to be able to deliver the harvested solar energy to the alternating current network. This is done in an inverter between the solar panels and the AC grid.

Electric cars with their associated battery storage require an inverter to convert the alternating current on the traditional alternating current network to direct current. Electric carriages are not only consumers of electrical energy, but can also store it temporarily in their batteries and return this energy to the alternating current network if desired, whereby conversion from direct current to alternating current is required.

All these inverters lead to energy loss, because the conversion from alternating current to direct current or vice versa, is always accompanied by energy loss.

These new developments raise the question of whether the alternating current network itself is better replaced by a direct voltage network.

The direct current network could make all the inverters superfluous, which could lead to simpler and cheaper electrical devices.

BE2018 / 5133

One of the reasons why AC distribution was preferred in the past is that AC voltage could be transformed to a much higher voltage through a transformer, which was not possible with DC voltage.

The use of a DC network makes it easier to connect distributed energy sources including electric vehicles to the DC network. This is because a DC network offers higher compatibility with distributed energy sources and renders synchronization of the frequency superfluous, which leads to more efficient and reliable connections with the distributed energy sources.

Where in a traditional alternating-voltage network the consumption of electrical energy was measured in an electricity meter installed at the customer, at best by a smart meter, which wirelessly communicates its measurements to a central server of the energy supplier, a direct-current network will give rise to the necessity of measuring multiple current draws and current outputs to the direct current network, where the supplier of the electrical current is not limited to one central supplier, but several distributed energy suppliers must be able to measure the electrical energy supplied by them and have it reimbursed by several distributed energy consumers.

BE2018 / 5133

This presupposes the presence of meters in the DC network at every point of energy consumption or energy supply and the ability to manage all these measurements through data communication.

The present invention has for its object to provide a solution to the aforementioned and other problems in that it provides a network for electrical energy and computer data transport, the network being an integrated network of a direct-current distribution network for supplying and recording electrical energy and a computer data network for recording and supplying computer data.

The network is preferably provided with smart sockets, each of which is provided with an electrical voltage channel and a computer data channel.

An advantage of such smart sockets is that it is possible to connect both DC-requiring devices and devices that require computer data.

The electrical voltage channel is preferably connected to a direct voltage network.

The computer data channel is preferably connected to an optical fiber data transport cable or to a wireless communication network, for example a 5G network. A similar computer data channel allows high data rates

BE2018 / 5133 in real time to an application server for example.

Furthermore, each smart socket preferably comprises one or more measuring units that measure the amount of electrical energy that is output and input via the electrical voltage channel of the smart socket and each smart socket is also connected to a data controller that measures the amount of computer data that is input and output via the computer data channel of the smart socket.

An advantage of these units of measurement and the data controller is that they make separate meters for electrical energy and for computer data and reading them superfluous.

Preferably, the measurements of the one or more units of measurement and the measurements of the computer data are transmitted by a data controller via the computer data channel wirelessly or via a cable or optical fiber to one or more central application servers of the network for electrical energy and data transport, so that no meter readings have to be passed on by the user or by an internet provider.

The one or more application servers pass on the amount of electrical energy consumed or produced and the amount of computer data transported to the providers of electrical energy and computer data, to allow the providers to invoice the consumers for the energy and data communication provided,

BE2018 / 5133 and to that end can also use the network for electrical energy and computer data transport.

Each smart socket is preferably provided with means for converting the electrical input voltage into a touch-proof electrical voltage that remains low enough to be safe for the user.

Each smart socket can connect the voltage channel and the computer data channel to the computer application modules via the outputs of the relevant smart socket in a touch-safe manner.

Hereby one or more computer application modules can be implemented for the public benefit, for a private consumer or producer, or for the benefit of both.

An advantage of such computer application modules is that they can be controlled by a public administration, for example for controlling public utilities such as street lighting, but can also be controlled by a private consumer to use the utility for private purposes.

An example of a computer application module is an application that controls the lighting of the public road by controlling an LED street lighting on a lighting pole that is itself part of the network for electrical energy and data transport. This application allows a public administration to dynamically control the street lighting _ΒΕ ΒΕ2018 / 5133 as desired at specific times and places.

Another example of a computer application module is an application that controls the charging or discharging of an electric vehicle or an electric battery when an electric vehicle or battery uses a smart socket on a charging pole, or on a lighting pole that serves as a charging pole.

Such a computer application will have to register the identity of the buyer and pass on the charged or discharged amount of electricity to the provider of the electrical energy.

Yet another example of a computer application module is a module that controls the operation of one or more surveillance and identification cameras, which may be mounted on or to one or more lighting posts or on a building, and which use a smart socket on a lighting pole that is itself part of the network for electrical energy and computer data transport.

Such an application allows the images recorded via the one or more surveillance and identification cameras to be transmitted via the computer data channel of a smart socket on a light pole to an application server for real-time display or for storage of the images in an archive.

Another example of a computer application module is one

BE2018 / 5133 module that controls the computer data communication for a 5G network, wherein an antenna for wireless communication is arranged on several public light poles, which antenna is connected to the computer data channel of a smart socket on a light pole on which the antenna is placed.

This makes it possible for every few tens of meters to have an antenna over which a large flow of computer data can be transmitted in real time.

DC generated by solar panels or wind turbines or other green energy sources can be stored via the DC network in storage batteries connected to the DC network via other smart sockets on the DC network, making the DC network more robust and reliable and suitable for computer application modules that have a long operating time and high computer data require a transfer speed. The storage batteries can be part of electric vehicles, home batteries in homes or decentralized batteries

With the insight to better demonstrate the characteristics of the invention, a few preferred embodiments of a network for electrical energy and computer data transport according to the invention are described below, with reference to the accompanying drawings, in which:

Figure 4 shows an electrical diagram for a smart socket 4 according to the invention, in which case a distribution voltage 16 is introduced as a two-phase voltage of +750 V and -750 V.

The data controller 23 is also provided with a power supply unit 30 which receives voltage from the voltage converter 19 and a separate voltage converter 34 which jumps in case the data controller 23 is disconnected from the mains.

The computer data network 3 is connected with its fiber optic cable 31 to an optical fiber to, for example, an ethernet converter 32 and via, for example, an ethernet switch 33 to the outputs 21. The data controller 23 registers and manages the energy and computer data consumption and is provided with an input port 35 to configure the smart socket and of a separate power supply unit 34, characterized in that the controller 23 remains active if the device is disconnected from the mains due to a short circuit, for example, so that in the event of an emergency, the data controller 23 can still reach the server.

The operation of the device 1 is simple and as follows.

The network according to the invention allows renewable or non-renewable electrical energy in the form of

BE2018 / 5133 direct voltage to be supplied via a public network to customers but also to be taken from producers and this via smart sockets · The electrical energy at the smart sockets is converted from a higher mains voltage to a lower and contact-safe direct voltage.

To this touch-safe DC voltage, multiple computer outputs can connect multiple computer application modules via different outputs, each of which can perform a different application.

For each computer application module, the amount of electrical energy consumed or supplied by a measuring unit is measured at the smart socket. These measurement data are exchanged or forwarded via a computer data network, the computer data network being connected to each output on the smart socket and this via an optical fiber network or via a wireless communication network.

Blockchain technology is used for securing data exchange and registering transactions. This technology ensures that customers and producers of electrical energy, but also customers and producers of computer data, receive correct information about the amount of energy and computer data supplied or received.

The number of different computer application modules is almost limitless.

BE2018 / 5133

A computer application module can, for example, be responsible for the street lighting and can control the LED lighting installed on lighting posts. It may be useful here to use the existing lighting poles to build in a suitable smart socket, or a separate housing for electronic devices and a smart socket can be provided at the lighting pole.

Another computer application module can, for example, provide for camera surveillance and identification by sending facial recognition or license plate recognition by cameras mounted on posts of light, or on surrounding buildings, and sending the recorded images to a surveillance room, or to archive recorded images. These cameras can be equipped for face recognition or number plate recognition, for example.

Yet another computer application module can control the charging or discharging of an electric vehicle 12 or an electric battery when a vehicle or battery uses a smart socket 4 on a charging station 13, or on a lighting pole 8 which serves as a charging station.

Another computer application module can manage and record direct current generated by solar panels 10 or wind turbines or other green energy sources that can be supplied via the network 1 to batteries of electric cars 12, for example, or to storage batteries in homes connected to the network 1 via other smart sockets 4 on the network 1.

BE2018 / 5133

Another computer application module can take care of the management of loudspeakers, mounted on the connected light poles, for example to broadcast in certain zones or at certain moments. For example, it is conceivable to send spoken messages on train platforms in this way.

Other computer application modules can provide security because they can use the input of all kinds of sensors to prevent or report risks such as fire, burglary or air pollution. Such modules can also provide security for the network itself. This allows them to detect and report unauthorized access to the housing of the smart sockets to a central server.

The computer application modules can also take the form of electronic fuses that measure the continuous direct current via a unit of measurement and, if a set value for peak current or differential current is exceeded, disconnect the electrical installation from the network, and distribute the necessary warnings via the computer data communication network.

The computer application modules can also take a form that makes it possible to guide self-driving vehicles in streets, but can also increase safety for steered vehicles, by driving warning signs with text or with traffic signs where this is useful.

BE2018 / 5133

All this leads to the fact that separate consumption meters in the homes no longer have to be read for solar cells and that the measurements for other utilities can be transmitted wirelessly via a nearby smart socket to the producers of these utilities.

All this can lead to the network and its components becoming increasingly smarter, by introducing new computer applications for internetof-things, as is still the case for portable telephones.

The present invention is by no means limited to the embodiments described by way of example and shown in the figures, but an integrated and cooperating network for electrical energy and computer data transport according to the invention can be realized in all shapes and sizes without departing from the scope of the invention as defined in the following claims.
