Description

Network standby power cut-off device for Internet of Things smart devices and its control method

[0001] The present invention relates to an Internet of Things (IoT) smart home / building system (hereinafter referred to as an “IoT smart system”), and more particularly, to a technology for reducing energy by blocking network standby power, which is power consumed by IoT smart electronic products (devices) (hereinafter referred to as “devices”) constituting the IoT system while simply waiting for the occurrence of an event without processing any event, and waste power wasted by the devices even when the devices are turned off.

[0002] Because it is impossible to turn off the devices in the current IoT smart system because it is not known when they will be controlled remotely, network standby power and wasted power are consumed.

[0003] This is leading to increased energy waste and carbon emissions, which is running counter to the global effort to achieve carbon neutrality.

[0004] Therefore, it is about a technology that reduces energy consumption and carbon emissions by turning off the power of devices when there is no event, thereby blocking network standby power and wasted power, and reducing wasted power to zero.

[0005] It also relates to a technology that allows you to manually 'turn off' the power of a device, rather than remotely, even when the device is nearby, thereby eliminating the hassle of having to control it remotely with a smartphone or other device even when the device is nearby.

[0006] To solve this, this is a technology that can intuitively turn the power of the device on and off, and can also be turned on and off remotely with a smartphone, while completely blocking network standby power and wasted power, thereby reducing carbon emissions and achieving carbon neutrality by killing two birds with one stone: convenience and energy savings.

[0007] IoT technology is currently being applied and expanded across various fields, and is being introduced into homes and buildings. As IoT technology becomes more widespread, interconnected IoT devices are constantly consuming network standby power and wasted power due to the uncertainty of when data will be transmitted or received, even when they are not performing any tasks or processing any events.

[0008] As the number of devices connected to the IoT increases exponentially, overall power consumption is expected to increase exponentially.

[0009] As a countermeasure to this increase in electricity consumption, the International Energy Agency (IEA) recommends that each country find and regulate measures to reduce unnecessary electricity waste.

[0010] Accordingly, the G20 summit has already selected an action plan to prepare measures to reduce such electricity consumption (January 2015).

[0011] However, to date, there remains no clear alternative other than minimizing the power consumption of individual semiconductor devices used in networks. Therefore, as the number of devices connected to the IoT increases, it's clear that the power consumption of these devices, both in standby mode and in standby mode, will increase exponentially.

[0012] To solve this problem, there still remains the issue of cost, as massive investments are needed to expand power plants and build related transmission and distribution infrastructure.

[0013] To address the aforementioned issues, standby power reduction devices disclosed in Korean Patent Application Nos. 10-2015-0003210, 10-2015-0009076, and 10-2015-0028858 filed by the applicant in the Republic of Korea have been proposed. However, these technologies are configured to connect a separate Ethernet connector or USB connector as a power supply means to control the supply of power to electronic devices only when necessary. This configuration may still cause inconvenience to users who must configure and connect a separate connector.

[0014] In addition, as a solution to the aforementioned problem, a system for completely blocking network standby power was proposed in patent application No. 10-2018-7026007 filed by the applicant in the Republic of Korea.

[0015] However, this technology completely blocks wasted power, but it has been difficult to commercialize because it requires a dedicated device connection device (outlet) and a dedicated power plug to deliver power for waking up the smart outlet and devices, and a control function to be added to the hub, so hub manufacturers, outlet manufacturers, and device manufacturers had to make modifications at the same time.

[0016] Additionally, manufacturing costs increased and many software products required significant modifications.

[0017] Additionally, there was the inconvenience of having to connect non-IoT devices and IoT devices that do not block network standby power to general outlets, and having to use separate IoT-only outlets for devices that block network standby power.

[0018] To solve this problem, a device connection device (outlet) is provided that can be used in common with three types of devices (non-IoT devices, general IoT devices, and network standby power blocking IoT devices of the present invention) in one type of device connection device (outlet).

[0019] Additionally, the device provides a network standby power cut-off, can be manually turned on and off, and can be remotely controlled even when the power is completely cut off.

[0020] Accordingly, the purpose of the present invention is to provide a network standby power cut-off device for IoT smart system devices and a control method thereof, which can reduce power consumption by supplying power to devices only when communication is required through a network while the devices are in a standby state or turned off (OFF) when no work is being performed by various devices connected to the Internet of Things (including, but not limited to, air conditioning and heating devices, TVs, refrigerators, washing machines, electric ranges, microwave ovens, dishwashers, security / disaster prevention devices, humidifiers / dehumidifiers, etc.).

[0021] Another object of the present invention is to provide a network standby power reduction device and a control method thereof, which can be configured by connecting a device connection device to an existing outlet in an existing building without separate construction, inserting a power plug of the device into the device connection device, and configuring an IoT smart system, and blocking the network standby power of the device and the standby power of the device itself when the device is turned 'off'.

[0022] To solve this problem, a device connection device (outlet) that can be used in common with three devices (general devices, IoT devices currently being produced and sold, and devices of the present invention) is provided.

[0023] Additionally, the device provides convenience and energy savings by blocking network standby power, allowing manual 'on' and 'off' operation, and remote control even when the power is completely cut off.

[0024] In order to achieve the above-described purpose, according to an exemplary aspect of the present invention, a device connection device (1) provides a means for always supplying power so that a general device, an IoT device, and a device (2) for blocking network standby power can be used in common, and a means for manually turning the device (2) on and off and remotely turning the device (2) on.

[0046] FIG. 1 is a drawing illustrating the configuration of one embodiment of an IoT smart system according to the present invention.

[0049] Figure 4 is a drawing illustrating an example of a configuration of a power 'on' and 'off' signal generation unit of IoT devices.

[0050] Hereinafter, with reference to the aforementioned FIGS. 1, 2, 3, and 4, the configuration and operating principle of one embodiment of the IoT smart system according to the present invention will be described in detail.

[0051] In Fig. 1, the configuration of the IoT smart system according to the present invention comprises: a smart hub (3) composed of a router that connects to an external network and a hub with added control functions, a device connection device (1) that supplies power to devices (2) that are connected to configure the system, and various devices (2).

[0052] Smart hub (3) can be installed in a specific location, such as a distribution panel, TV, or refrigerator in a house or building.

[0053] The device connection device (1) is composed of a communication unit (11) that communicates with the smart hub (3) and transmits data to the control unit (13), a power supply (12) that supplies power required for the device connection device (1), a control unit (13) that operates, analyzes, and stores data received from the communication unit (11) and controls the power 'on' and 'off' of the device (2) by including a memory and a processor, one or more power supply / cut units (14) that supply power to the device (2) according to the control of the control unit (13), one or more insertion ports (15) into which the power plug (500) of the device (2) can be inserted, and a power plug (500) that connects to a wall outlet (600).

[0054] In the case of a new building, the device connection device (1) can be installed by embedding it in the wall.

[0055] In the above, the power supply / cutoff unit (14) is configured to supply power to the insertion port (15) through a relay contact, and is configured with a transistor Q1 and a relay K1 so that power can be remotely supplied or cut off to the device (2) according to the control of the control unit (13).

[0056] Meanwhile, the configuration of the device (2) is composed of a power plug (500) inserted into the insertion port (15) of the device connection device (1) as a passage for supplying power to the device (2), a device power supply / cutoff unit (21) for supplying / cutting power to the device (2), a device power unit (22) for generating and supplying power required for the device when power is supplied, a device control unit (23) for collecting, calculating, storing, and controlling various data to control the device, and a communication unit (24) for performing communication with the outside when power is supplied to the device.

[0057] The device (2) is plug in and play when powered.

[0058] In addition, the configuration of the above-mentioned device power supply / cutoff unit (21) includes a manual power 'on', 'off' unit (220) configured with a power switch SW and FET Q3 to enable manual 'on' and 'off', a power supply detection unit (230) configured with a capacitor C2 and FET Q4 to detect when power is to be supplied remotely while the device is powered off, a driving unit (240) configured with FET Q5, FET Q6 and photocoupler PC1 to maintain the power supply / cutoff state by the control of the device control unit (23), an 'on, 'off' signal generating unit (210) configured with a diode D3, FET Q7 and photocoupler PC2 to generate an 'on', 'off' signal to transmit this signal to the control unit (23) when the power is manually turned 'on' and 'off', and a rectifier that rectifies when AC power is supplied through a power plug (500) and a bridge diode BR1 that rectifies. It consists of.

[0059] This rectifier can directly connect the power (DC) stored in the ESS by generating solar power without converting it to AC by the inverter, thereby reducing energy waste by eliminating the energy loss that occurs when converting to AC by the inverter.

[0060] When explaining the operation of the present invention, first, the method of supplying power to the device (2) is explained. The contacts a, c and contacts a1, c1 of the relay K2 constituting the power supply / cutoff section (14) of the device connection device (1) are always connected, so that power is always supplied to the insertion port (15), so that the currently distributed and used general devices and IoT devices can be used like a general outlet by inserting a power plug into the insertion port (15).

[0061] In addition, in the case of the devices (2) of the present invention, power is always supplied to the device (2) regardless of whether the power is 'on' or 'off', but when the power is 'off', the power is cut off by the power supply / cutoff unit (21), so that the network standby power and wasted power in the device become zero.

[0062] Initialization setup steps

[0063] After the IoT smart system is built, power is supplied

[0064] Device registration

[0065] In order to register devices (2) in the device connection device (1), when a registration command signal is received in the control unit (13) through the hub (3), the communication unit (11) of the IoT device connection device (1), and the device communication unit (24) of the device (2), the corresponding output O1,... On is controlled in the microcomputer of the control unit (13) to set the corresponding #1,...#n, and necessary information such as the ID of the device (2) connected to the insertion port (15) to control the devices (2) is registered in the memory of the control unit (13).

[0066] Power supply / cutoff to device (2)

[0067] Since the power supply / cutoff part (14) of the device connection device (1) must always be kept powered on for the general devices and IoT devices currently in use, the contacts a, c of the relay K2 and the contacts a1, c1 are always connected, so that power is always supplied to the insertion port (15), and the general devices and IoT devices currently in use can be used like a general outlet by inserting a power plug into the insertion port (15).

[0068] In addition, there is a method of manually supplying and cutting off power to the device (2) of the present invention and a method of remotely supplying / cutting off power to a device whose power has been cut off.

[0069] The operation of the device power supply / cutoff unit (21) is explained based on Fig. 3.

[0070] Manual power 'on' operation

[0071] When power is supplied through the power plug (500) of the device (2), it is rectified at the bridge BR and divided by the resistors R1 and R2, and Vs is applied to one side of the power switch SW. When the power switch SW is pressed, the voltage VS is applied to the gate of FET Q3, so that FET Q3 is turned on, and current flows from Oa to Ob of the device power unit (22), so that the device power unit (22) generates the power required for the device (2) and supplies it to the device control unit (23) and the device communication unit (24).

[0072] At this time, the device control unit (23) controls the output O4 to light the photocoupler PC1 LED of the driving unit (240). At this time, the transistor of PC1 is turned on, and the voltage of the transistor collector is applied as 0 V, which is applied to the gate of FET Q6, so that FET Q6 is turned off, and VS is applied to the gate of FET Q5, so that FET Q5 is turned on, and even if the switch SW is 'opened', power is continuously supplied to the device power unit (22).

[0073] Manual power 'off' operation

[0074] When the power switch SW is pressed once to turn the device (2) 'off' while it is in operation, voltage VS is applied to the gate of FET Q7 through diode D3 only while B of the 'on', 'off' signal generating unit (210) is being applied, so that FET Q7 is turned 'on', and the LED of photocoupler PC2 lights up, turning the transistor 'on'. At this time, an 'off' signal is transmitted to the device control unit (23) through A of the transistor collector.

[0075] When this signal is detected, the device control unit (23) controls the output O4 to turn off the LED of the photocoupler PC1 of the driving unit (240) to turn off the transistor, so that the voltage VS is applied to the gate of the FET Q6 through the resistor R3, and the FET Q6 is turned on. At this time, 0 V is applied to the gate of the FET Q5, so that the FET Q5 is turned off, thereby blocking the current flowing to the device power supply unit (22), and thus the power supplied to the device (2) is blocked, so that the wasted power becomes zero. When the resistance values ​​of the resistors R1 and R2 are 500 MΩ, a current of approximately 0.44 μA flows, and the wasted power becomes zero to the point of being negligible.

[0076] Remote power 'on' operation

[0077] When the device (2) is operated remotely from a smartphone or cloud while the power is cut off, if the IP, Mac address, ID, etc. are received through the smart hub (3), the control unit (13) of the device connection device (1) controls the transistor Q1 of the power supply / cutoff unit (14) to turn it 'on', thereby energizing the relay K1 and 'opening' the relay contacts a, c, a1, c1, and then turns the transistor Q1 'off' again to de-energize the relay K1 and connect the relay contacts a, c, a1, c1, thereby cutting off the power supplied to the insertion port (15) and then controlling it to supply the power again.

[0078] In this way, the power supplied to the device (2) is momentarily cut off and then supplied again, and the capacitor C2 of the power supply detection unit (230) of the device power supply / cutoff unit (21) is momentarily short-circuited, so that voltage VS is applied to the gate of FET Q4, and FET Q4 is turned on.

[0079] At this time, current flows from Oa to Ob of the device power supply unit (22), so that the device power supply unit (22) generates the power required for the device and supplies it to the device control unit (23) and the device communication unit (24). When power is supplied, the device control unit (23) controls the output O4 to light the photocoupler PC1 LED of the driving unit (240).

[0080] At this time, the transistor of the photocoupler PC1 is turned on, and the voltage of the transistor collector is 0 V, which is applied to the gate of FET Q6, so that FET Q6 is turned off, and the voltage VS is applied to the gate of FET Q5, so that FET Q5 is turned on, and even if the switch SW is 'opened', power is continuously supplied to the device power supply unit (22). When power is supplied, the device executes an event by plugging in and playing.

[0081] Meanwhile, when the capacitor C2 is fully charged, the circuit is in an 'open' state, so that the voltage applied to the gate of FET Q4 is blocked, and FET Q4 is turned 'off'. In this way, power can be supplied remotely even when the power of the device (2) is 'off', that is, the network standby power and wasted power are blocked and zero.

[0082] This provides an IoT smart system that provides convenience and prevents energy waste.

The control circuit (13) may be configured to control the switch to re-establish the electrical connection after the electrical connection is disconnected, so as to provide power provided from the power plug (500) to the external electronic device (2).

[0086] For example, the control circuit (13) may be configured to receive the signal through the communication circuit (11) while the external electronic device (2) is turned off.

[0087] For example, the control circuit (13) may be configured to control the switch to re-establish the electrical connection in order to turn on the external electronic device (2).

[0088] For example, the control circuit (13) may be configured to control the switch to transmit an AC signal of the power plug (500) to the external electronic device (2) connected to the socket (15) while the electrical connection is established.

[0089] For example, the electronic device (1) may further include a transistor (Q1) having a gate electrode connected to the control circuit (13), a source electrode connected to ground, and a relay (K1) connected to a drain electrode of the transistor (Q1). The control circuit (13) may be configured to change the states of the transistor (Q1) and the relay (K1) to control the switch to release the electrical connection based on receiving the signal while the electrical connection between the power plug (500) and the socket (15) is established through the switch. The control circuit (13) may be configured to change the states of the transistor (Q1) and the relay (K1) again to control the switch to re-establish the electrical connection after the electrical connection is released.

[0090] For example, the switch may be a first switch. The first switch may be composed of a second switch and a third switch. The control circuit (13) may be configured to control the second switch and the third switch to change the states of the transistor (Q1) and the relay (K1) to release the electrical connection based on receiving the signal while the electrical connection between the power plug (500) and the socket (15) is established through the second switch and the third switch. The control circuit (13) may be configured to control the second switch and the third switch to change the states of the transistor (Q1) and the relay (K1) again to re-establish the electrical connection after the electrical connection is released.

[0091] For example, the electronic device (1) may further include a converter (12) connected to the power plug (500). The converter (12) may be configured to transmit a direct current signal from an alternating current signal of the power plug (500) to the communication circuit (11) and the control circuit (13).

[0092] For example, the control circuit (13) may include a memory. The control circuit (13) may be configured to receive another signal for registration of the external electronic device (2) through the communication circuit (11) before receiving the signal. The control circuit (13) may be configured to store information about the external electronic device (2) in the memory to control the external electronic device (2) based on receiving the other signal while the electrical connection between the power plug (500) and the socket (15) is established through the switch.

[0093] For example, the switch may be a first switch. The socket (15) may be a first socket (15). The external electronic device (2) may be a first external electronic device (2). The electrical connection may be a first electrical connection.
