Description

Control device of temperature control system

The present invention relates to a control device of a temperature control system, and more particularly, to a temperature control system that can provide additional functions such as WiFi communication, voice output, TFT LCD, as well as basic functions for controlling a temperature control system. It relates to a control device.

The temperature control system includes various cooling / heating devices such as an air conditioner and a boiler for controlling room temperature, and a control device for controlling these devices. Cooling / heating devices (hereinafter, referred to as 'main units') are generally installed separately from the space where the user mainly works, such as the indoor ceiling and the utility room. Therefore, in order to allow the user to conveniently operate the claim value, a control device connected to the main device is separately provided. The control device is installed in a place where the user's operation is easy, such as an indoor wall, so that the user can comfortably control the claim value. That is, the user can operate the control device installed on the indoor wall to turn on / off the power of the main device or to raise or lower the room temperature.

The control device is connected to the main device by two DC power lines to receive power for operation from the main device and to communicate with the main device. The claimed value can be connected to a commercial power supply (eg AC 220 [V]) to supply the power necessary for the operation of the control unit via a DC power line. In addition, the main device and the control device may perform mutual communication by adjusting the voltage of the DC power line.

For example, the main unit (or control unit) recognizes '0' when more than 10 [V] is received from the control unit (or main unit), and recognizes as '1' when less than 10 [V] is received. It is assumed that the control device is set in advance to operate at a direct current 5 [V].

At this time, the assertion value may alternately transmit a voltage greater than 10 [V] and less than 10 [V], and the controller may recognize the signal received from the main device using the received voltage. In addition, the control device may be changed to a voltage of 5 [V] necessary for a basic operation such as control of the main device by smoothing the voltage received from the main device through the provided regulator.

However, when more current is used for the operation of the control device, the basic voltage transmitted from the main device falls, which causes a communication error or cannot generate a voltage required for the basic operation of the control device. In the previous example, the asserted value sent 12 [V] to the controller and sent a signal corresponding to '0'. However, when much current is used in the controller and the voltage of 12 [V] drops to 9 [V], the controller In this case, '0' transmitted by the main device may be misrecognized as '1', which may cause a communication error. In addition, in the above example, when a large amount of current is used in the controller and the basic voltage drops below 5 [V], the controller may not be able to perform the basic operation properly. Therefore, when the current used by the control device is greater than the predetermined current, there is a hassle that a separate power line is connected to the control device or the claim value needs to be replaced.

In accordance with the recent development of wireless communication, a color display (for example, TFT LCD, etc.), wireless communication (for example, Wi-Fi) as well as a function for controlling the power and / or temperature of the main device to the control device (hereinafter referred to as 'main function') , Bluetooth, etc.), voice output, such as more power consumption than the main function (hereinafter referred to as 'additional function') has been increased. As a result, the above-mentioned problems are further raised.

1 is a configuration diagram showing a temperature control system 10 according to an embodiment of the present invention.

Referring to FIG. 1, a temperature control system 10 according to an embodiment of the present invention may include a main device 100, a user device 200, and a control device 300.

The main device 100 may include a cooling / heating device and an air conditioner used in a home or a public building. For example, the main device 100 may include a boiler, an air conditioner and / or a hot air fan. The main device 100 may be connected to the control device 300 by two DC power lines to supply preset power to the control device 300 and to communicate with the control device 300. Therefore, the main device 100 may receive a signal corresponding to the user's operation from the control device 300 to control the output and / or power state.

For example, the user may operate the control device 300 to increase the room temperature, the control device 300 may generate a signal corresponding to the user's operation and transmit the signal to the main device 100 through the power line, The main device 100 may perform an operation for increasing the room temperature through a signal received from the control device 300. In another example, the user may operate the control device 300 to turn on or off the power supply of the main device 100, and the control device 300 may provide a signal corresponding to the user's operation. The power supply may be generated and transmitted to the main device 100 through the power line, and the main device 100 may be powered on or off through a signal received from the control device 300.

The user device 200 may be connected to the temperature control device 300 to control the temperature control device 300. For example, the user device 200 may include a remote controller and / or Near Field Communication (NFC), Bluetooth, Zigbee, Wi-Fi, and Wireless. It may be a terminal supporting local area communication such as a wireless LAN. In addition, the user device 200 may be connected to the temperature control device 300 through the Internet to control the temperature control device 300 remotely. This is because the temperature control device 300 can be connected to the Internet through wired or wireless.

The user may operate the user device 200 to control the temperature control device 300, the user device 200 may generate a signal corresponding to the user's operation and transmit it to the connected temperature control device 300. The temperature control device 300 may perform an operation corresponding to a signal received through the user device 200. Accordingly, the user may control the operation of the master device 100 even by remotely operating the user device 200.

The control device 300 may be connected to the main device 100 through a power line to receive power and communicate with the main device 100. That is, the control device 300 may operate by receiving power from the main device 100 through a power line, and may exchange various signals with the main device 100. The control device 300 may generate a signal corresponding to a user's manipulation and transmit the signal to the master device 100. Accordingly, the main apparatus 100 may perform an operation corresponding to the manipulation of the user. In addition, the control device 300 may provide visual information to the user by displaying the signal received from the main device 100 through the screen provided. As such, the operation of controlling the temperature of the main device 100 and displaying the current operating state of the main device 100 corresponds to the main function of the control device 300.

Meanwhile, in addition to the main function, the control device 300 communicates with the user device 200 connected through a wireless communication network, outputs a current operation state of the main device 100 by voice, or drives a color display. Function can also be performed. These additional functions consume more power than the main functions. However, since the main device 100 may be set to transmit power corresponding to the main function operation of the control device 300, the control device 300 operates the additional function by using the power supplied from the main device 100. In order to provide a separate power source. Hereinafter, the operation of the control device 300 will be described in more detail with reference to FIG. 2.

2 is a block diagram of the control device 300 according to an embodiment of the present invention.

Referring to FIG. 2, the control device 300 includes a control unit 310, a main function unit 320, an input unit 330, a charging unit 340, a first switch unit 350, an additional function unit 360, and a first operation unit. 2 may include a switch 370, the main power supply 380, the main power monitoring unit 385 and the third switch 390.

Power supplied from the main device 100 may be input to the main power supply unit 380. The main power supply 380 may include a regulator. Therefore, the power supplied from the main device 100 may be smoothed to a voltage (hereinafter, referred to as 'main voltage') required for the main function in the main power supply unit 380.

The main function unit 320 may perform a main function of the control device 300 with a main voltage input from the main power supply unit 380. For example, the control device 300 may sense an indoor temperature using a temperature sensor (not shown) provided and display information on the indoor temperature. In this case, the indoor temperature information may be displayed through a black and white display (not shown) instead of a color display (not shown). The main function unit 320 may include a temperature sensor, a black and white display, a backlight LED of a black and white display, and the like.

Power supplied from the master device 100 may be input to the communication unit 395. The communication unit 380 may determine the voltage supplied from the main device 100 and recognize the signal transmitted from the main device 100. For example, it is assumed that the communication unit 395 is set in advance to determine '0' when recognizing a voltage of 10 [V] or more and '1' when recognizing a voltage of 10 [V] or less. At this time, when the voltage supplied from the main device 100 is determined to be 12 [V], the communication unit 395 recognizes a signal corresponding to '0', and when the voltage supplied from the main device 100 is determined to be 8 [V]. A signal corresponding to '1' can be recognized. The communicator 395 may output the recognized signal to the controller 310. `

On the other hand, the user may operate the input unit 330 to set the room temperature, the input unit 330 may generate a signal corresponding to the user's operation to output to the control unit 310. The controller 310 may control the communicator 395 to transmit a signal input through the input unit 330 to the master device 100. The communication unit 395 may change the voltage supplied from the main device 100 under the control of the controller 310. As a result, the communicator 395 may transmit a signal corresponding to the control of the controller 310 to the master device 100. Since the communication unit 395 transmits a signal to the main device 100, it will be apparent to those skilled in the art, so a detailed description thereof will be omitted.

As a result, the main apparatus 100 may perform an operation corresponding to the manipulation of the input unit 330 of the user. For example, when the user manipulates the input unit 330 to maintain the room temperature at 18 degrees, the input unit 330 may generate and output a signal corresponding to the user's operation, and the control unit 310 may When the signal is input, the temperature setting information may be generated and transmitted to the master device 100 (via the communication unit 395). Therefore, the main device 100 may be operated to maintain the room temperature at 18 degrees according to the received temperature setting information. According to the method described above, the control device 300 may control the output of the main device 100 to correspond to the temperature set by the user.

As described above, the input unit 330 may output a signal corresponding to the user's manipulation to the controller 310. The input unit 330 may include a keypad, a touch pad, and the like, and generate a signal for power on / off, temperature control, and / or activation of additional functions according to a user's operation. 310).

The main power may be supplied to the controller 310, the main function unit 320, the input unit 330, and / or the additional function unit 360 to perform the main function of the control device 300.

In addition, the power supplied from the main device 100 may be supplied to the charging unit 340 to charge the charging unit 340. The charging unit 340 may include components capable of charging and supplying power such as a rechargeable battery and a charging circuit. The charging unit 340 may supply power charged by the control unit 310 to the additional function unit 360 (hereinafter referred to as “charging power”). The charging source supplied from the charging unit 340 to the additional function unit 360 may be electric power of the main power or more. For example, it is assumed that the current required for normal operation of the main function is 100 [mA] and the current required for normal operation of the additional function is 300 [mA]. In this case, the current of the charging source provided to the additional function unit 360 by the charging unit 340 may correspond to 300 [mA].

The additional function unit 360 may include at least one of a wireless communication unit (not shown), a speaker unit (not shown), and a color display unit (not shown). For example, the additional function may be one or more of a voice output function through a speaker (not shown) and a color output function through a color display. Additionally, the additional function may include a wireless communication function such as a near field communication (NFC) function, a Bluetooth communication function, a Zigbee communication function, and a Wi-Fi communication function.

The additional function unit 360 may be operated using the main voltage supplied from the main power supply unit 380 or the charging pressure supplied from the charging unit 340. The additional function unit 360 may be selectively supplied with a main voltage or a charging pressure under the control of the controller 310. First, it is assumed that the main voltage is supplied to the additional function unit 360. Hereinafter, the case where the additional function unit 360 is operated by the main voltage is referred to as 'main power mode'. In the main power mode, the additional function unit 360 may perform a limited operation. For example, assume that the additional function unit 360 includes a wireless communication module. Since the wireless communication module may not use much current when receiving data, the wireless communication module may operate normally in the main power mode. In addition, the speaker unit (not shown) of the additional function unit 360 may be activated in the main power mode to maintain the standby state (without the audio output). In addition, the color display unit (not shown) of the additional function unit 360 may be activated in the main power mode to maintain a standby state (without outputting an image).

In the main power mode, the first switch unit 350 may connect the main power unit 380 and the additional function unit 360 in an activated state. In the main power mode, the second switch unit 370 may not connect the charging unit 340 and the additional function unit 360 in an inactive state.

When a preset event occurs, the controller 310 may activate the second switch unit 370 and inactivate the first switch unit 350 to connect the charging unit 340 and the additional function unit 360. . Hereinafter, the case where the additional function unit 360 is operated by the charging pressure is referred to as the 'charging power mode'.

For example, the controller 310 may control the additional function unit 360 to operate in the charging source mode according to a user's manipulation of the input unit 330. The user may operate the input unit 330 to output the current set temperature as a voice. The speaker unit (not shown) may not be able to output voice normally with main power. This is because the speaker unit (not shown) uses a large amount of current when outputting voice, thereby lowering the voltage of the main power supply below a preset voltage. Accordingly, the controller 310 may output an activation signal to the second switch unit 370 to operate the additional function unit 360 in the charging source mode through the signal input from the input unit 330. In addition, the controller 310 may output an inactivation signal to the first switch unit 350 so that the additional function unit 360 operates in the charging source mode through the signal input from the input unit 330. The second switch unit 370 may connect the charging unit 340 and the additional function unit 360 by an input of an activation signal. The first switch unit 350 may release the connection between the main power supply unit 380 and the additional function unit 360 by the input of the deactivation signal.

In the above-described example, the speaker unit (not shown) has been described as an example among various functions included in the additional function unit 360, but this is only an example. When the color display unit (not shown) outputs an image, much current is used as in the case where the speaker unit (not shown) outputs an audio, and thus the same operation as the above example may be performed. In addition, since a wireless communication unit (not shown) (for example, a Wi-Fi module, a Bluetooth module, etc.) uses a lot of current when transmitting data to the user device 200, the same operation as the above example may be performed. Therefore, the controller 310 may control the additional function unit 360 to operate in the charging source mode when a preset operation is performed because a large amount of current is used in the additional function unit 360. Hereinafter, a signal for allowing the additional function unit 360 to operate in the charging source mode is referred to as a 'charging mode signal'.

For another example, the controller 310 may control the additional function unit 360 to operate in the charging source mode based on the charging source mode information received from the main device 100. The main device 100 may transmit the charging source mode information (for example, information for notifying that the power of the main device 100 is ON / OFF) to the controller 310 about the current operation state. The controller 310 outputs a voice through a speaker unit (not shown) or an image through a color display unit (not shown) to notify the user when charging source mode information on the current operation state of the main apparatus 100 is input. The information may be outputted or transmitted to the user device 200 connected through a wireless communication network. In this case, the controller 310 may output an activation signal to the second switch unit 370 so that the additional function unit 360 operates in the charging source mode. In addition, the controller 310 may output an inactivation signal to the first switch unit 350. The second switch unit 370 may connect the charging unit 340 and the additional function unit 360 by an input of an activation signal. The first switch unit 350 may release the connection between the main power supply unit 380 and the additional function unit 360 by the input of the deactivation signal.

For another example, the controller 310 may control the additional function unit 360 to operate in the charging source mode by the charging source mode signal received from the user device 200. The user device 200 may transmit a charging source mode signal to the wireless communication module of the additional function unit 360 to transmit information about the current set temperature to the user device 200 according to a user's manipulation. As described above, the wireless communication module may normally receive a signal from the user device 200 even in the main power mode. Therefore, the controller 310 may control the additional function unit 360 to operate in the charging source mode in order to transmit the information about the current set temperature to the user device 200 according to the charging source mode signal. This is because a large amount of current may be used by the wireless communication module to transmit data to the user device 200. In this case, the controller 310 may output an activation signal to the second switch unit 370 to operate the additional function unit 360 in the charging source mode. In addition, the controller 310 may output an inactivation signal to the first switch unit 350 so that the additional function unit 360 operates in the charging source mode. The second switch unit 370 may connect the charging unit 340 and the additional function unit 360 by an input of an activation signal. The first switch unit 350 may release the connection between the main power supply unit 380 and the additional function unit 360 by the input of the deactivation signal.

For another example, the controller 310 may monitor the current used by the additional function unit 360 to control the additional function unit 360 to operate in the charging source mode. The controller 310 may output an activation command to the second switch unit 370 when the current used by the additional function unit 360 becomes greater than or equal to a preset threshold current. In addition, the controller 310 may output an inactivation command to the first switch unit 350 when the current used by the additional function unit 360 becomes greater than or equal to the threshold current. The second switch unit 370 may connect the charging unit 340 and the additional function unit 360 by an input of an activation signal. The first switch unit 350 may release the connection between the main power supply unit 380 and the additional function unit 360 by the input of the deactivation signal.

Thereafter, the controller 310 may determine whether to release the charging source mode. For example, the controller 310 may release the charging source mode when the operation of the additional function unit 360 according to the manipulation of the input unit 330 of the user is completed. The controller 310 may cancel the charging source mode when the audio output of the speaker unit (not shown) is completed, the image output of the color display unit (not shown) is completed, or data transmission to the user device 200 is completed. . For another example, the controller 310 may release the charging source mode when the operation of the additional function unit 360 according to the signal received from the main device 100 is completed. For another example, the controller 310 may release the charging source mode when the operation of the additional function unit 360 according to the signal received from the user device 200 is completed. As another example, the controller 310 may release the charging source mode when the current used by the additional function unit 360 is less than the threshold current. In this case, the controller 310 may release the charging source mode when the state in which the current used by the additional function unit 360 is less than the threshold current is maintained for a predetermined time or more. This is because the current used by the additional function unit 360 may momentarily be lower than the threshold current and then become higher than or equal to the threshold current.

The controller 310 may output an activation command to the first switch unit 350 to release the charging source mode, and may output an inactivation command to the second switch unit 370. The first switch unit 350 may connect the main power supply unit 380 and the additional function unit 360 by an input of an activation command. The second switch unit 370 may release the connection between the charging source unit 340 and the additional function unit 360 by the input of the deactivation command. As a result, the additional function unit 360 may be operated in the main power mode again.

Meanwhile, the power supplied from the main device 100 may be input to the charging unit 340 to charge the charging unit 340. In this case, the charging unit 340 may receive power through the main power monitoring unit 385 or the main power supply unit 380. Also, the charging unit 340 may be connected to the main power monitoring unit 385 or the main power supply unit 380 through the third switch unit 390.

The main power monitoring unit 385 may monitor the power supplied from the main device 100 to prevent the charging unit 340 from using the excessive power to lower the voltage of the main power. For example, the main power monitoring unit 385 may monitor the voltage of the main power output from the main power unit 380. The main power monitoring unit 385 may output an inactivation command to the third switch unit 390 so that the charging unit 340 cannot consume power when the voltage of the main power becomes less than or equal to a preset threshold voltage. As the third switch unit 390 is deactivated, the connection between the main power monitoring unit 385 and the charging unit 340 may be released. When the threshold voltage is set to 4.5 [V] in advance, the main power monitoring unit 385 may deactivate the third switch unit 390 when the main power becomes 4.5 [V] or less.

For another example, the main power monitoring unit 385 may monitor the voltage supplied from the main device 100. In the main power monitoring unit 385, when the voltage supplied from the main device 100 is less than or equal to a preset threshold voltage, the third switch unit 390 may be deactivated so that the charging unit 340 cannot consume power. This is to allow the main power supply unit 380 to output a constant main power supply by smoothing the voltage supplied from the main device 100. However, when the voltage supplied from the main device 100 is lower than the threshold voltage by the power used by the charging unit 340, the main power supply unit 380 may not be able to output a constant main power. Accordingly, the main power monitoring unit 385 may output an inactivation command to the third switch unit 390 when the voltage supplied from the main device 100 becomes less than or equal to a preset threshold voltage. In this case, the threshold voltage can be set to a value higher than the main voltage. The third switch unit 390 may release the connection between the main power monitoring unit 385 and the charging unit 340 according to the deactivation command.

By the above operation, the charging unit 340 may not perform the charging operation.

To perform the operation. In this case, the main power monitoring unit 385 may send an activation command to the third switch unit 390 when the state in which the voltage supplied from the main device 100 and / or the main voltage exceeds the threshold voltage is maintained for a predetermined time or more. You can print This is because the voltage supplied from the main device 100 and / or the main voltage may momentarily exceed the threshold voltage and fall back below the threshold voltage.

In the above description, the main power monitoring unit 385 controls the third switch by monitoring the voltage and / or the main voltage supplied from the main device 100, but the operation of the main power monitoring unit 385 is performed by the controller 310.

Referring to FIG. 3, the control device 300 may be installed at a location that can be easily manipulated by a user such as an indoor wall to control the main device 100. The control device 300 may detect the indoor temperature and output the indoor temperature information on the screen. In addition, the user may perform a button input for setting the indoor temperature. For example, if the user desires the room temperature to 26 degrees, the set temperature may be set to 26 degrees by using the button input for temperature control and the set temperature information displayed on the screen. Accordingly, the control device 300 may transmit a signal for controlling the output of the main device 100 to the main device 100 according to the temperature set by the user.

For example, it is assumed that the set temperature of the control device 300 is set to 18 degrees by the user. In this case, the control device 300 may generate a signal for operating the main device 100 and transmit the signal to the main device 100, and the main device 100 may be activated by the signal to perform an operation for lowering the room temperature. . On the other hand, when the room temperature falls below 18 degrees, the control device 300 may generate a signal for stopping the operation of the main device 100 and transmit the signal to the main device 100, and the main device 100 may not be fired by the signal. Can be activated.

The control device 300 may execute the additional function according to the user's operation. It is assumed that a user manipulates a button to use an additional function. In this case, the control device 300 may enable the additional function to operate using the rechargeable battery provided in order to allow the additional function corresponding to the user's operation to be normally operated. The control device 300 may transmit data to the user device 200 connected through the wireless communication network using the provided rechargeable battery. In addition, the control device 300 may output a voice using the provided rechargeable battery. For example, when the user changes the set temperature, the control device 300 may output the temperature information according to the voice using the rechargeable battery. In addition, when the user presses a heating use button, a hot water use button and other buttons, the control device 300 may output a voice message for notifying the start and end of an operation corresponding to the button using a rechargeable battery.

In addition, since the control device 300 may be connected to the user device 200 through a wireless communication network, the user operates the user device 200 to control the temperature of the main device 100 and control the power on / off, change the set temperature, and reserve the bedtime. You can also use features such as hot water. In this case, the control device 300 may transmit the information indicating that the operation corresponding to the user's operation is normally performed to the user device 200 by using the rechargeable battery.

In addition, the control device 300 uses a color display device such as a TFT LCD to display the set temperature information, power state, indoor temperature information, and / or hot water and heating functions of the main device 100 using the provided rechargeable battery. You can also output a variety of images. The control device 300 may not only display simple information such as text, but also output the temperature change in a graph in real time, or may output a variety of colors and videos so that the user state information is easily recognized.

4 is a flowchart illustrating a method of using power of a control apparatus according to an embodiment of the present invention.

Hereinafter, a power usage method of the control device 300 according to an embodiment of the present invention will be described in detail with reference to FIG. 4. Each step to be described below may be steps performed by each component of the control device 300 described with reference to FIG. 2, but collectively referred to as being performed in the control device 300 for convenience of understanding and description. Explain. Therefore, the subject performing the steps performed below may be omitted.

In step S410, the additional function is operating in the main power mode.

In operation S420, a preset event is generated to determine whether to operate through a rechargeable battery equipped with additional functions. The preset event is one of a case in which a user manipulates an input device, a signal from the main device 100 is input, a signal from the user device 200 is input, and a current used by the additional function unit is greater than or equal to a threshold current. May correspond to one or more.

In operation S430, when it is determined in operation S420 that the battery is to be operated through the rechargeable battery having the additional function, the first switch is inactivated and the second switch is activated. As a result, the additional function may be disconnected from the main power source and connected to the rechargeable battery.

In step S440, the additional function is operated in the charging source mode.

In step S450, it is determined whether the charging source mode is released. For example, when the operation according to a preset event is completed, the charging source mode may be released. For another example, when the current used by the additional function is less than the threshold current, the charging source mode may be released. In this case, the charging source mode may be released when the current used by the additional function unit is maintained below the threshold current for a predetermined time or more.

In step S460, when it is determined that the charging source mode is released, the first switch is activated and the second switch is inactivated. As a result, the additional function may be connected to the main power and disconnected from the rechargeable battery.

In step S470, the bookkeeping function is again operated in the main power mode.

Hereinafter, a charging method of the control device 300 according to an embodiment of the present invention will be described in detail with reference to FIG. 5. Each step to be described below may be steps performed by each component of the control device 300 described with reference to FIG. Explain. Therefore, the subject performing the steps performed below may be omitted.

In step S520, the power supplied from the main device 100 is monitored. This is to prevent the charging unit 340 from lowering the voltage of the main power supply using excessive power. For example, the controller 300 may determine whether the voltage of the main power supply (which is output by smoothing the power supplied from the main device 100) is equal to or less than the threshold voltage. As another example, the control device 300 may determine whether the voltage supplied from the main device 100 is less than or equal to the threshold voltage.

In operation S530, when the voltage of the main power supply is less than or equal to the threshold voltage or the voltage supplied from the main device 100 is less than or equal to the threshold voltage, the third switch may be deactivated.

In operation S540, since the rechargeable battery is not supplied from the main device 100 by deactivation of the third switch, the charging operation cannot be performed.

In operation S550, when the voltage supplied from the main apparatus 100 and / or the main voltage exceeds a preset threshold voltage, the third switch may be activated (operation S560).

In operation S570, the rechargeable battery may be supplied with power from the main device 100 by the activation of the third switch to perform the charging operation.
