The present invention relates to an energy harvesting remote control device, and more particularly, to an energy harvesting remote control device capable of generating operating energy and individually remotely controlling an electric device using a low-power communication method.

Various types of electrical equipment are installed in the building. For example, a number of installations, such as lighting fixtures, water-saving devices, and water exchangers, are installed at various locations in a home.

In the past, these facilities were controlled by operating individual switches. For example, in order to operate the lighting fixture in the kitchen, the lighting fixture in the kitchen could be operated by opening and closing a switch located in the kitchen.

In recent years, as Internet of Thing (IoT) technology and short-range network technology have developed, it is possible to control each electric device by connecting to a network. However, recently introduced IoT and local area networks have been pointed out as a problem in that individual electric devices are discharged or the battery of the controller is easily discharged because a lot of power is consumed due to frequent signal transmission and reception between individual facilities and control devices.

As the concept of low-power communication has been introduced to solve this, low-power wireless communication technologies such as BLE (Bluetooth Low Energy) have been established as a method of communicating with electric devices. In order to control an electric device using such a low-power wireless communication method, there is a need for development of a new type of control technology.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a block diagram illustratively illustrating an energy harvesting remote control device according to an embodiment of the present invention. Referring to FIG. 1, the energy harvesting remote control device 100 includes a transmitting and receiving unit 110, a button unit 120, a storage unit 130, a control unit 140, and a setting button unit 150.

The transmitter/receiver 110 may perform wireless communication with a remote control target electric device. At this time, the transceiver 110 may be implemented by applying Bluetooth Low Energy (BLE) technology. The transceiver 110 may communicate with a device supporting Bluetooth communication or a device supporting BLE.

Specifically, when the button 120 is pressed by the user to generate the operating energy (operating voltage), the transmitting/receiving unit 110 then transmits the control signal generated by the control unit 140 to the controlled electric device. At this time, the transmitting and receiving unit 110 may transmit a control signal in a broadcasting manner. The transmitting and receiving unit 110 may also be implemented in a method other than a broadcasting method.

The transmitter/receiver 110 uses only BLE technology, which is a wireless communication technology optimized for low power consumption than the maximum data transmission rate, and thus consumes only a minimum of one hundredth of the average power required by Bluetooth Classic. In addition, the transceiver 110 has a peak current consumption of at least 15mA, so it is 3 minutes 1 level higher than that of the Bluetooth classic (more than 40mA).

According to an embodiment of the present invention, the transmitting and receiving unit 110 operates at low power. That is, the transmission/reception unit 110 may have different power consumption according to the advertising packet transmission interval. For example, if the advertising packets are transmitted at 1000 ms intervals, the current consumption per hour is tens to hundreds of microamperes (A). The current consumption can be sufficiently operated by operating energy (instantaneous power = about 0.33 mWs) generated by the button unit 120 described below.

The transmitting and receiving unit 110 may be applied with a low-power Bluetooth beacon (BLE beacon) technology that can transmit data to a corresponding electrical device without receiving a separate authentication procedure from another electrical device.

The button unit 120 generates a control signal for controlling the electric device to be controlled. The button unit 120 is provided with an energy harvesting device to generate operating energy (operating voltage) by the energy harvesting device when the key button of the button unit 120 is pressed. Detailed description of this will be described with reference to a separate drawing. In addition, the button unit 120 may generate a specific control signal for controlling a specific control target device according to the operation mode of the remote control device set by the setting button unit 150 described below.

The storage unit 130 temporarily stores operating software, firmware, various setting values, GPIO information, mode information, and the like for driving the energy harvesting remote control device 100. The storage unit 130 may modify or overwrite pre-stored information under the control of the control unit 140. The storage unit 130 may be configured as a memory element integrated in the controller 140 or may be configured as a separate memory element. The storage unit 130 may be composed of a combination of various types of temporary or non-transitory memory elements such as ROM, EPROM, EEPROM, RAM, and SRAM.

The control unit 140 controls the overall operation of the transmission/reception unit 110, the button unit 120, the storage unit 130, and the setting button unit 150. The control unit 140 may be implemented with a central processing unit (CPU), a micro processing unit (MPU), and a micro controller unit (MCU). The control unit 140 may be implemented as a micro control unit (MPU) configured inside a low power Bluetooth. When the key button of the button unit 120 is pressed, the control unit 140 is driven by operating energy generated instantaneously. Next, the control unit 140 checks (recognizes) the operation mode set by the setting button unit 150 and checks and confirms the set value of the energy harvesting remote control device 100 according to the checked (recognized) operation mode. A control signal is generated according to the set value, and the generated control signal is controlled to be wirelessly broadcast through the transceiver 110.

The setting button unit 150 functions as a button for setting the operation mode of the energy harvesting remote control device 100. The operation method of the setting button unit 150 may be implemented in various ways, such as a sliding method, a rotary method, a button method, or a combination thereof. Hereinafter, when the sliding method is mainly described as an operation method, a user may select an operation mode of the energy harvesting remote control device 100 as a first mode using the setting button unit 150. Here, selecting the operation mode means selecting a type of control target device that can be controlled by the energy harvesting remote control device 100. For example, when the user starts the operation of the energy harvesting remote controller 100 by pressing the button 120 while the first mode is selected using the setting button unit 150, the corresponding energy harvesting remote controller 100 Will operate in the first mode. Here, when the first mode is a setting mode for controlling light 1, the corresponding energy harvesting remote control device 100 may execute various controls for light 1. If the user selects the second mode using the setting button unit 150 of the energy harvesting remote control device 100, the energy harvesting remote control device 100 operates in the second mode. As described above, according to the present invention, various types of electric devices can be individually controlled by one energy harvesting device 100. Hereinafter, a principle in which an operating voltage is generated by pressing a key button of the button unit 120 will be described.

2 is a view for explaining the structure of the button portion of the energy harvesting remote control device according to an embodiment of the present invention by way of example. Referring to FIG. 2, the button unit 120 may include one or more key buttons. According to an embodiment, the button unit 120 may include a plurality of key buttons. The button unit 120 shown in FIG. 2(a) is an example consisting of one keypad and one energy harvesting device.

Specifically, the button unit 120 is composed of a keypad 121, an energy conversion means 122 and a signal generation means 123 under the keypad 121. The keypad 121 is implemented by a mechanical keyboard method. In the case of a mechanical keyboard method, it may be implemented as a contact type or a contactless type. The lower portion of the keypad 121 includes an energy harvesting device that converts mechanical energy into electrical energy. The energy harvesting device converts mechanical energy into electrical energy by the energy conversion means 122 when a mechanical force F is applied to the keypad 121.

The energy conversion means 122 shown in FIG. 2(b) changes the magnetic force lines formed by the magnets and coils by changing the positions of the magnets and coils by the mechanical force F. Due to the change in the magnetic force line, an induced voltage is generated according to electromagnetic induction. This method is a principle in which mechanical energy applied by an external force is converted into electrical energy by a coil-magnet method provided in the energy conversion means 122.

3 is a view for explaining an energy harvesting device according to an embodiment of the present invention by way of example. The energy conversion means 122 shown in FIG. 3 operates in a coil-magnet method. When the energy conversion means 122 receives mechanical energy by external force, the position of the magnet becomes relatively variable with respect to the coil, so that the primary induction voltage (electrical energy) according to electromagnetic induction due to the change in the magnetic force line between the coil and the magnet ) Occurs. The generated primary induced voltage is rectified, and the rectified voltage is converted to generate a direct current operating voltage.

4 is a view exemplarily showing a cross-section of the energy conversion means shown in FIG. 3. Referring to Figure 4 (a), the energy conversion means 122 according to an embodiment of the present invention includes a magnetic force conversion device 12, the coil core 14 and the coil 16. In addition, the energy conversion means 122 includes a magnetic element having a permanent magnet 1220 and two coil pieces 1240. The magnetic force conversion device 12 is U-shaped and has a connection part for connecting between two parallel legs and two legs. The connecting portion has a through opening in the middle. The coil core 14 is rod-shaped. The end of the coil core 14 is pushed through the opening of the connection portion of the magnetic force conversion device 12. The coil core 14 is arranged in the middle between them in parallel with the legs of the magnetic force conversion device 12. The coil 16 has a number of windings wound around the coil core 14. The coil 16 may fill the space between the coil core 14 and the leg of the magnetic force conversion device 12. The electrical insulating layer occurs between the coil 16 and the coil core 14 and between the coil 16 and the magnetic force conversion device 12, respectively. The free ends of the ribs of the magnetic force conversion device 12 and the coil core 14 may each be designed to be the same length as the extensions of the free ends of the coil 16 toward the magnetic component. It is possible to make the legs and the coil cores 14 end to each other. The legs and the free ends of the coil core 14 form a contact to the coil piece 1240 of the magnetic component.

The permanent magnet 1220 has a magnetic N pole and a magnetic S pole. With regard to the magnetic force conversion device 12, the permanent magnet 1220 has a first pole of the permanent magnet 1220 on the side of the first rib, and a second pole of the permanent magnet 1220 on the side of the other rib. It is oriented so that. Thus, the magnetic field lines extend in parallel to the concept line connecting the legs of the magnetic force converting device 12 in the permanent magnet 1220 transverse to the longitudinal extension direction of the coil core 14. The permanent magnet 1220 may be configured as a rectangle. The coil piece 1240 is in the form of a plate arranged on both sides of the permanent magnet 1220. In particular, the coil piece 1240 is arranged on the end surface of the permanent magnet 1220 forming the coil. Each coil piece 1240 extends beyond the permanent magnet 1220. The extension is placed on the side of the permanent magnet 1220 facing the coil 16. The permanent magnet 1220 is in a position spaced from the end face of the coil core 14. Among the extensions of the coil piece 1240, the coil piece 1240 protrudes into an intermediate space between the coil core 14 and the leg of the magnetic force conversion device 12. The permanent magnet 1220 has a first coil piece 1240 of the coil pieces 1240 projecting into an intermediate space between the coil core 14 and one of the first ribs of the magnetic force converter 12, and the second coil piece ( 1240) defines a space between the coil core 14 and the second leg of the magnetic force conversion device 12. The contact surface of the first coil piece 1240 and the second coil piece 1240 facing the first leg, the contact surface of the coil core 14 and the contact surface of the first rib facing the first coil piece 1240 and the second coil piece It is equal to the distance between the contact surfaces of the coil core 14 facing (1240).

The magnetic component composed of the permanent magnet 1220 and the coil piece 1240 can be moved relative to the coil core 14 and the magnetic force conversion device 12. To this end, the magnetic components are arranged to be movable. In particular, the magnetic component can move along a conceptual line connecting the legs of the magnetic force conversion device 12. In the first position, the magnetic component is biased toward the first leg. In this case, the first contact surface of the first coil piece 1240 contacts the contact surface of the first rib, and the first contact surface of the second coil piece 1240 contacts the first contact surface of the coil core 14. In the second position, the magnetic component is biased towards the second leg. In this case, the second contact surface of the first coil piece 1240 contacts the second contact surface of the coil core 14, and the second contact surface of the second coil piece 1240 is the first coil piece of the contact surface of the second rib The first and second contact surfaces of 1240 are respectively disposed to face each other. Likewise, the first and second contact surfaces of the coil core 14 and the coil piece 1240 are disposed opposite each other. As indicated by the arrow, the magnetic flux at the first position passes through the first coil piece 1240 into the first end of the magnetic force converting device 12, the connection portion of the magnetic power converting device 12 to the coil core 14 And the coil core 14 is inserted into the second coil piece 1240.

When the magnetic component is in the first position, when the magnetic body is in the second position, the direction of magnetic flux of the coil core 14 is opposite to the direction of magnetic flux of the coil core 14. When the magnetic component changes from the first position to the second position or vice versa, the direction of magnetic flux of the coil core 14 is reversed and a voltage is induced in the coil 16. When the magnetic component is moved by an external force applied from the top in this way, the applied mechanical energy can be converted into electrical energy.

5 is a view for explaining the control mode change of the control target device according to the operation of the setting button unit according to an embodiment of the present invention by way of example. Referring to FIG. 5, the control unit 140 controls the transmission/reception unit 110 to transmit a control signal to the control target device. At this time, the control unit 140 generates different control signals for the same key according to the setting state of the setting button unit 150.

In FIG. 5, the sliding type setting button unit 150 is illustrated. The mode can be switched by sliding the setting button unit 150 in the X direction. In addition, it may be implemented by a push button type or a rotation button type. The physical implementation form of the setting button unit 150 may be variously designed and changed. Hereinafter, a description will be given focusing on an example implemented with a sliding button method.

Specifically, when the user places the setting button unit 150 in the first mode (see FIG. 5(b)), the control unit 140 starts the operation when the energy harvesting remote controller 100 is the first GPIO. Recognize that you are in a state The process of the controller 140 recognizing the operation state is as follows. The control unit 140 starts an operation according to an operating voltage generated when the button unit 120 is pressed.

Here, the button unit 120 may include at least one button or may be composed of a plurality of buttons. When configured with a plurality of key buttons, it can be divided into a power key for generating operating power and a function key for controlling a control target device. When the user presses the power key among the button units 120, operating energy is generated, and when the function key is pressed, a control signal is generated according to a key value corresponding to the pressed function key. At this time, the power key of the button unit 120 has an energy conversion means 122, but the function key does not have an energy conversion means 122. The function key may be composed of a plurality of key buttons, and the key values of the plurality of key buttons are matched with the key value table according to the control mode.

The control unit 140 in which the operation is started can recognize that the setting of the energy harvesting remote controller 100 is GPIO 1 because the setting button unit 150 is in the first mode position. The control unit 140 reads the key value table mapped to the GPIO 1 from the storage unit 130 and reads the first set value of the energy harvesting remote control device 100. The controller 140 controls the transceiver 110 to generate a first control signal according to a key value generated when a (function) key is pressed by a user, and transmit the generated first control signal in a broadcasting manner. Here, the first control signal is all transmitted to the peripheral electric device, but it is possible to control the lighting 1 matched with GPIO 1. If there are other electrical devices set to GPIO 1, they can be controlled together.

When the user places the setting button unit 150 in the second mode in the same manner (see FIG. 5(c)), the control unit 140 recognizes the setting of the energy harvesting remote control device 100 as GPIO 2, GPIO The second set value table matched to the second mode corresponding to 2 is read from the storage unit 130, and the second set value of the high energy harvesting remote control device 100 is read. The key value of the function key of the button unit 120 is mapped to the second set value table, which generates a second set of control signals for controlling the water saver.

When the user places the setting button unit 150 in the third mode in the same way (see FIG. 5(d)), the control unit 140 recognizes the setting of the energy harvesting remote control device 100 as GPIO 3 and GPIO The third set value table matched to the third mode corresponding to 3 is read from the storage unit 130, and the third set value of the energy harvesting remote control device 100 is read. The key value of the function key of the button unit 120 is mapped to the third set value table, which generates a third set of control signals for controlling the exchanger.

6 is a view for explaining the control signal generation operation according to the type of key in the first mode according to an embodiment of the present invention. Referring to FIG. 6, the first mode refers to an operation mode of the energy harvesting remote controller 100 when the button position of the setting button unit 150 is in the first position P_1. At this time, when the first key (Key_1) is pressed, a control signal for turning on lighting 1 is generated (see FIG. 6(a)). Similarly, when the second key (Key_2) is pressed, a control signal for turning off lighting 1 is generated (see FIG. 6(b)). That is, in the first mode state, the function keys of the button unit 120 respectively generate a control signal according to the information matched with the first set value table. The case of changing the mode will be described below with reference to a separate drawing. Depending on the embodiment, a button equipped with an energy harvesting device may be configured as a one button, and when a single button is pressed once, twice in succession, three times in succession, or controlled multiple times in succession. It can be configured to control the device to be controlled by generating different signals.

7 is a view for explaining an operation of switching from the first mode to the second mode according to an embodiment of the present invention. Referring to FIG. 7, when the button position of the setting button unit 150 is positioned at the first position P_1 (see FIG. 7(a) ), it means operating in the first mode, and the setting button unit 150 When the button position is positioned at the second position P_2 (see FIG. 7(b)), it means that the button operates in the second mode. In the first mode operation, the lighting 1 can be controlled, and in the second mode operation, the water saving can be controlled. Accordingly, when the first key (Key_1) is pressed in the first mode operation, a control signal for turning on the lighting 1 is generated, and when the first key (Key_1) is pressed in the second mode operation, a control signal for turning on the water-storage is generated. . The operation control process of the energy harvesting remote control device 100 and the control target device 200 will be described below with reference to separate drawings.

8 is a diagram illustrating various modified embodiments of a setting button unit for controlling a GPIO according to another embodiment of the present invention. Referring to FIG. 8, the energy harvesting remote controller 100 according to another embodiment of the present invention may be configured with a plurality of rotary method buttons (see FIG. 8(a) ). Alternatively, the energy harvesting remote controller 100 according to another embodiment of the present invention may be configured with a plurality of on-off type buttons (see FIG. 8(b)). According to various embodiments of the present invention, the structure of the setting button unit 150 for adjusting the value of GPIO is implemented in a physical manner, but configured to control three or more digits of GPIO, and can be set to a plurality of GPIO setting modes. .

9 is a view for explaining an operation of controlling a control target device in a first mode operation according to an embodiment of the present invention. Referring to FIG. 9, when the user sets the setting button of the setting button unit 150 in the first mode (GPIO 1 setting mode), the user presses at least one key (power key) of the button unit 120 to operate. Energy (operating voltage) is generated. The operation of the control unit 140 is started by the generated operation energy. The control unit 140 recognizes the setting position of the setting button unit 150 to recognize the operation mode of the energy harvesting remote control device 100. The control unit 140 generates a first control signal (control object: GPIO 1 device, control content: brightness UP) matched to the pressed key according to the recognized operation mode and broadcasts it through the BLE transmitter 110.

At this time, the two electric devices L_1 and D_1 both receive the first control signal. The illuminator L_1 is set to GPIO 1, and the water saver D_1 is set to GPIO 2. When the first control signal is received, a control operation according to the received control signal is executed when the GPIO value included in the control signal matches the GPIO value included in the control signal.

In FIG. 9, since the first control signal is to control the electric device set to GPIO 1, the water saver D_1 is set to GPIO 2, so even if the first control signal is received, it is not controlled according to the first control signal. On the other hand, since the illuminator L_1 is set to GPIO 1, when the first control signal is received, it is controlled according to the first control signal, thereby performing an operation to increase the brightness of the illumination.
