Description

AN ELECTRICAL SOCKET SYSTEM AND A METHOD FOR AN ELECTRICAL SOCKET
SYSTEM
FIELD OF THE INVENTION
The present invention relates to an electrical socket system and a method for an electrical socket system.
BACKGROUND OF THE INVENTION
Known home automation systems are centralised systems comprising a plurality of sensors and controls. The home automation systems are typically expensive and customized to the home.
Power strips are used when several electrical devices are in proximity.
Known power strips can have a mechanical master switch to turn all connected electrical devices on and off.
However, known electrical sockets and power strips comprise only an operation which switches the connected electrical device on or off. Therefore, there is a need for an electrical socket and a power strip which allow the mode of operation of the electrical device to be monitored, identified and controlled.
BRIEF DESCRIPTION OF THE INVENTION
An object of the present invention is to provide an electrical socket system and a method for an electrical socket system such as the disadvantages of — the prior art are dissolved or at least alleviated.
The objects of the invention are achieved by an electrical socket system according to an independent claim 1 and a method for an electrical socket system according to an independent claim 13. The preferred embodiments of the invention
D are disclosed in the dependent claims.
N 25 The invention is based on the idea of providing an electrical socket 5 system. The electrical socket system comprises a power inlet, a power outlet o comprising a socket opening for accommodating a plug, a controller coupled to the
T power inlet, an electronic switch coupled to the power inlet, the electronic switch a coupled between the power outlet and the controller, and an electricity meter = 30 coupled between the power outlet and the electronic switch. The system is
S configured to identify a stand-by mode of operation of a plugged electrical device > when the electrical device is set to a stand-by mode, where the controller is configured to close the electronic switch allowing current to flow through it, the electricity meter is configured to measure a stand-by power, and the controller is configured to save the stand-by power, or the system comprises a communication unit and a server system, the communication unit is configured to provide communication between the controller and the server system, the server system is configured to instruct the controller to identify the stand-by mode, where the controller is configured to close the electronic switch allowing current to flow through it, the electricity meter is configured to measure a stand-by power, the communication unit is configured to communicate the measured stand-by power to the server system, the server system is configured to analyse the measured stand-by power to provide the stand-by power, the communication unit is configured to communicate the stand-by power to the controller, and the controller is configured to save the stand-by power. The system is configured to monitor a mode of operation of the plugged electrical device, where the electricity meter is configured to measure the power. The system is configured to control the mode of operation of the plugged electrical device, where the controller is configured to open the electronic switch preventing current to flow through it when the measured power corresponds the stand-by power.
An advantage of the invention is that it monitors, identifies and controls the plugged electric devices individually. In the invention the power consumption of the plugged electric device in the stand-by mode is determined by measuring it with an electricity meter. As the electrical socket system detects based on the power consumption of the plugged electric device and the measured stand-by power of the plugged electric device that the plugged electric device is in a stand- by mode it automatically switches off the power outlet. This reduces the cost of a continuous stand-by energy consumption by reducing the stand-by time.
The electrical socket system may be a stand-alone system meaning it > can perform its function without being integrated for instance to an expensive
DO house automation system. This means the electrical socket system monitors, = identifies and controls the plugged electric devices locally. The electrical socket = system provides a cost-effective way to control individual electrical devices and it
T 30 isan easy system to install. = The electrical socket system may also comprise a server system and a + necessary communication unit for a communication between the controller and 3 the server system. The server system, which comprises an external server system 2 or a part of the controller, provides analysis for the electrical socket system. The
N 35 analysis comprises for instance: calculating an arithmetic mean power, defining a lowest /highest power and/or calculating standard deviation.
In an embodiment of the invention the electrical socket system may comprise the controller which is configured to open the electronic switch after a delay when the measured power is lower than the stand-by power plus a margin, where the margin comprises 5-50% of the stand-by power and the delay comprises 0-60 min. Preferably, the margin comprises 10-20% of the stand-by power.
Preferably, the delay comprises 5-15 min.
The use of a margin reduces the risk that a temporary lower power usage of the electronic device is interpreted as a stand-by mode which causes the electric device to be switched off. Further, the use of a delay prevents a repeated switching on and off of the electrical device in a short period of time.
In another embodiment of the invention the electrical socket system may be configured to identify a standard mode of operation of the electrical device, where the controller is configured to close the electronic switch, the electricity meter is configured to measure a standard power, and the controller is configured — to save the standard power, or the system comprises a communication unit and a server system, the communication unit is configured to provide communication between the controller and the server system, the server system is configured to instruct the controller to identify the standard mode of operation, where the controller is configured to close the electronic switch, the electricity meter is configured to measure a standard power of the electrical device during an operation mode, the communication unit is configured to communicate the measured standard power to the server system, the server system is configured to analyse the measured standard power to provide the standard power, the communication unit is configured to communicate the standard power to the controller, the controller is configured to save the standard power. The system is > configured to monitor the mode of operation of the electrical device, where the
O electricity meter is configured to measure the power of the electrical device during = an operation mode. The system is configured to control the mode of operation of = the electrical device, where the controller is configured to open the electronic
T 30 switch when the measured power is higher than the standard power plus a second = margin. The second margin may comprise 5-40% of the standard power. + Preferably, the second margin comprises 10-15% of the stand-by power. 3 In the identification of the standard mode of the operation of the
O
5 plugged electrical device the power consumption of the plugged electrical device is
N 35 monitored over a time period. The time period may be an operation cycle of the electric device, a predetermined time period or a time period defined by the user.
The defining of the time period by the user may be performed with a user device to the controller or through the server system. The standard power is defined from the measured energy consumption data and it is the peak power, for instance.
The identification of the standard mode of the operation of the plugged electrical device provides additional safety for the user. If the energy consumption of the electrical device increases suddenly from it's ordinary energy consumption it can indicate a technical obsolescence, wear and tear or a technical failure of the electrical device. The electrical socket system can monitor the mode of the operation and when a limit value is exceeded, i.e. the measured power consumption is more than the standard power plus a second margin, the electrical socket system automatically switches off the power outlet. Providing the standard power at the controller reduces the response time of the system.
In a further embodiment of the invention the margin as a percentage may be higher than a second margin as a percentage.
The first margin is related to the energy consumption of an electrical device and the second margin is related to a safe operation of an electrical device.
Therefore, the user may find the safe operation more relevant than the energy saving and reguire a more accurate action.
In a further another embodiment of the invention the system may comprise a main switch coupled to the controller, and the controller is configured to switch on or switch off the electrical connection of the main switch.
The controller can prevent the manual operation of the main switch when necessary. For instance, the manual use of the main switch may be disabled during the night time in order to prevent its use by a pet.
In a yet further another embodiment of the invention the controller may > be configured to save energy consumption data from the electricity meter. This
O allows tracking of energy consumption on-line and history information. For = instance, if the energy consumption of the electric device increases slowly in the = course of time it can indicate a technical obsolescence and wear and tear.
T 30 In an embodiment of the invention the electrical socket system may be = remotely operable with a user device. The user device may comprise a smart phone + or a tablet. The remote operation may use Wi-Fi or ZigBee wireless communication 3 systems, for instance. The use of Wi-Fi allows an over-the-air update, e.g. the
O
5 wireless delivery of new software to the controller or the wireless delivery of data
N 35 from controller to a user device.
The user device may communicate with a server system if the server system is provided. For instance, the user may use the user device to communicate with an external server system, and the external server system communicates with the controller by means of a communication unit.
In another embodiment of the invention the controller may comprise 5 oneormoreprocessors,a memory and input/out peripherals, or a microcontroller, or a system on a chip.
In a further embodiment of the invention the electrical socket system may comprise two or more power outlets each comprising the electronic switch and the electricity meter coupled between the power outlet and the controller. The electrical socket system allows each power outlet comprising a socket opening for accommodating a plug to be monitored, identified and controlled independently of the other power outlets.
In a further another embodiment of the invention the electrical socket system may comprise a wall socket provided on a wall of a building connected to mains electric power.
In an embodiment of the invention a power strip comprises an enclosure for a socket and an electrical power cable connected to the enclosure, the electrical power cable comprising a plug for connecting the power strip to a power supply, and the enclosure comprises the electrical socket system.
The power strip may comprise 1-10 socket openings and preferably 2- 6.
The electrical socket system allows each power outlet comprising a socket opening for accommodating a plug to be monitored, identified and controlled independently of the other power outlets provided in the same power — strip. > In another embodiment of the invention the power strip may further
O comprise an electric switch button configured to start the system configured to = identify a stand-by mode of operation of a plugged electrical device when the = electrical device is set to a stand-by mode, and/or configured to start the system
T 30 configured to identify a standard mode of operation of the electrical device. = By means of the electric switch button the user can manually start the + identification of the stand-by power and/or the identification of the standard 3 power. For instance, each power outlet may be connected to a corresponding 2 electric switch button.
N 35 The invention is based on the idea of providing a method for an electrical socket system for monitoring, identifying and controlling a mode of operation of an electrical device connected to the electrical socket system. The method comprises connecting a power inlet of the electrical socket system to a power supply for providing electricity to a controller and an electronic switch of the electrical socket system and connecting a plug of an electrical device to a power outlet of the electrical socket system. The method comprises identifying a stand-by mode of operation of the electrical device by: setting the electrical device to a stand-by mode, closing the electronic switch allowing current to flow through it with the controller, measuring a stand-by power with an electricity meter of the electrical socket system coupled between the power outlet and the electronic — switch, and saving the stand-by power to the controller, or instructing the controller to identify the stand-by mode with a server system, where closing the electronic switch allowing current to flow through it with the controller, setting the electrical device to a stand-by mode, measuring a stand-by power with an electricity meter of the electrical socket system coupled between the power outlet and the electronic switch, communicating the measured stand-by power to the server system with a communication unit, analysing the measured stand-by power with the server system providing the stand-by power, communicating the stand- by power to the controller with the communication unit, and saving the stand-by power to the controller. The method comprises monitoring the mode of operation — of the electrical device by: measuring the power with the electricity meter. The method comprises controlling the mode of operation of the electrical device by: opening the electronic switch preventing current to flow through it with the controller when the measured power corresponds the stand-by power.
An advantage of the invented method is that the plugged electric devices are monitored, identified and controlled. As a plugged electric device is > detected to be in a stand-by mode the power outlet is automatically switched off. It
O reduces the cost of a continuous stand-by energy consumption by reducing the = stand-by time. = In an embodiment of the invention the method may comprise opening
T 30 the electronic switch with the controller after a delay when the measured power is = lower than the stand-by power plus a margin, where the margin comprises 5-50% + of the stand-by power and the delay comprises 0-60 min. Preferably, the margin 2 comprises 10-20% of the stand-by power. Preferably, the delay comprises 5-15 5 min.
N 35 The use of a margin reduces the risk that a temporary lower power usage of the electronic device is interpreted as a stand-by mode. Further, the use ofa delay prevents a repeated switching on and off of the electrical device in a short period of time.
In another embodiment of the invention the method may comprise identifying a standard mode of operation of the electrical device by: setting the electrical device to an operation mode, closing the electronic switch with the controller, measuring a standard power with an electricity meter of the electrical socket system coupled between the outlet and the electronic switch, and saving the standard power to the controller, or instructing the controller to identify the standard mode of operation with a server system, where closing the electronic — switch with the controller, setting the electrical device to an operation mode, measuring a standard power with an electricity meter of the electrical socket system coupled between the power outlet and the electronic switch, communicating the measured standard power to the server system with a communication unit, analysing the measured standard power with the server system providing the standard power, communicating the standard power to the controller with the communication unit, saving the standard power to the controller. The method comprises monitoring the mode of operation of the electrical device by measuring the power with the electricity meter. The method comprises controlling the mode of operation of the electrical device by opening the electronic switch with the controller when the measured power is higher than the standard power plus a second margin.
In the method the identification of the standard mode of the operation of the plugged electrical device provides additional safety for the customer. If the energy consumption of the electrical device increases suddenly it can indicate a technical obsolescence, wear and tear or a technical failure of the electrical device. > The electrical socket system can monitor the mode of the operation and when a

T 30 The identification of the mode of the operation of the plugged electrical = device is preferably performed after plugging an electrical device to a power outlet. + It is not necessary to repeat the identification of the mode of the operation of the 3 plugged electrical device if the same electrical device remains plugged to the same
