Description

  The present invention relates to a technique for reducing power consumption of a remote control device and standby power of an electric device main body in a remote control device for remotely controlling the electric device and an electric device to be controlled.

  An electrical device that is operated by a remote control device includes a receiving unit, a switch unit, an internal circuit, and the like. The receiving unit receives electromagnetic waves from the outside and generates electric power. The power generated by the receiving unit is sent to the switch unit. When power is supplied to the switch unit, the power is turned on by the power. When the power is turned on, the switch unit is configured to conduct the current supplied from the external power source to the internal circuit of the electric device and operate the electric device (for example, Patent Document 1).

Embodiment 1 FIG.
A configuration example of remote control system 100 according to Embodiment 1 of the present invention is shown in FIG. As shown in FIG. 1, the remote control system 100 includes an electric device control unit 1 and a remote control device 2.

  The electric device control unit 1 includes a control unit 11, a transmission / reception unit 12, a radio wave detection unit 13, an antenna 14, an operation unit 15, and a power source 16. The electric device control unit 1 is a component of an electric device that operates using electricity, and controls the electric device based on information transmitted from the remote control device 2 or information input from the operation unit 15.

  The control unit 11 controls the original function and communication function of the electric device controlled by the electric device control unit 1. The control unit 11 includes a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores an operation program of the CPU, a RAM (Random Access Memory) that serves as a work area, and the like.

  The transmission / reception unit 12 exchanges information with the remote control device 2 by radio signals.

  The radio wave detection unit 13 detects a radio signal (transition signal) from the remote control device 2. The radio wave detection unit 13 detects a radio wave having a frequency in the same band as the frequency transmitted and received by the transmission / reception unit 12. The radio wave detection unit 13 includes a filter, a multi-stage detection circuit, a rectifier circuit, a low power consumption type amplifier that operates with a current of several microamperes, a voltage comparator that similarly operates with several microamperes, and the like. That is, the radio wave detection unit 13 is configured to operate with standby power of about several microwatts. Note that, with such a low power consumption design, the signal intensity that can be detected by the radio wave detection unit 13 is lower than the signal intensity that can be processed by the transmission / reception unit 12.

  The antenna 14 receives a radio signal from the remote control device 2. The antenna 14 transmits a radio signal to the remote control device 2.

  The operation unit 15 is an interface for a user to operate an electric device. The operation unit 15 includes switches, buttons, various keys, and the like. The operation unit 15 inputs operation information corresponding to a user operation to the control unit 11.

  The power source 16 generates power consumption of the electric device control unit 1 of the electric device from a commercial AC power source or the like. The power source 16 may be a battery having a capacity capable of supplying power necessary for the operation of the electric device control unit 1 of an electric device, such as a dry battery or a secondary battery.

  The electric device control unit 1 is configured to be switchable between a standby mode with low power consumption and a normal mode that is a normal operation mode as an operation mode.

  In the standby mode, the function of the transmission / reception unit 12 is turned off to reduce power consumption. In the normal mode, the function of the transmission / reception unit 12 is turned on. The control unit 11 switches to the standby mode according to the program stored in the control unit 11 and switches to the normal mode according to a signal from the radio wave detection unit 13 or the operation unit 15. In the standby mode, other configurations of the electric device control unit 1 may be switched so as to suppress power consumption.

  The remote control device 2 includes a control unit 21, a transmission / reception unit 22, a radio wave detection unit 23, an antenna 24, an operation unit 25, a display unit 26, and a battery 27. The remote control device 2 is a device for a user to operate an electric device.

  The control unit 21 controls a remote control function and communication with the electric device control unit 1. The control unit 21 includes a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores a CPU operation program, a RAM (Random Access Memory) that serves as a work area, and the like.

  The transmission / reception unit 22 exchanges information with the electrical device control unit 1 by radio signals.

  The radio wave detection unit 23 detects a radio signal from the electric device control unit 1. The radio wave detection unit 23 detects a radio wave having a frequency in the same band as the frequency transmitted and received by the transmission / reception unit 22. The radio wave detection unit 23 includes a filter, a multi-stage detection circuit, a rectifier circuit, a low power consumption type amplifier that operates with a current of several microamperes, and a voltage comparator that similarly operates with several microamperes. That is, the radio wave detection unit 23 is configured to operate with standby power of about several microwatts. Note that, with such a low power consumption design, the signal strength that can be detected by the radio wave detection unit 23 is lower than the signal strength that can be processed by the transmission / reception unit 22.

  The antenna 24 receives a radio signal from the electric device control unit 1. The antenna 24 transmits a radio signal to the electric device control unit 1.

  The operation unit 25 is an interface for a user to operate an electric device. The operation unit 25 includes switches, buttons, various keys, and the like. The operation unit 25 inputs operation information corresponding to the user operation to the control unit 21.

  The display unit 26 is configured by an LCD (Liquid Crystal Display) or the like, and appropriately displays an operation state (control state) of an electric device, an operation screen, and the like. In addition, you may comprise the operation part 25 and the display part 26 with a touchscreen type display.

  The battery 27 supplies power consumption of the remote control device 2. The battery 27 has a capacity capable of supplying power necessary for the operation of the remote control device 2, such as a dry battery or a secondary battery.

  The remote control device 2 can be switched between an operation mode between a standby mode with low power consumption and a normal mode that is a normal operation mode.

  In the standby mode, the function of the transmission / reception unit 22 is turned off to reduce power consumption. In the normal mode, the function of the transmission / reception unit 22 is turned on. The control unit 21 switches to the standby mode according to the program stored in the control unit 21, and switches to the normal mode according to signals from the radio wave detection unit 23 and the operation unit 25. This point is the same as that of the electric equipment control unit 1.

  In addition, since the remote control device 2 includes the display unit 26, the display on the display unit 26 is also switched to low power consumption in the standby mode.

  For example, the display unit 26 needs to continuously display that the electric device main body is operating. The display unit 26 is composed of an LCD, and its power consumption depends on the refresh rate and the number of segments that drive the liquid crystal for display. Hereinafter, control in the standby mode of the display unit 26 will be described.

  By limiting the number of segments for driving the liquid crystal, it is possible to display at a reduced frame rate without deteriorating the appearance. Using this characteristic, as shown in FIG. 3, immediately after the operation, the frame rate is increased to a predetermined normal speed, and during the period of the standby mode, the number of segments to be displayed is, for example, 1/2, 1 In addition to the minimum necessary number such as / 3 and 1/4, the frame rate is suppressed and the power consumption is reduced.

  As another method of controlling the display unit 26 in the standby mode, the standby mode period is displayed by intermittently displaying the liquid crystal display only for a predetermined period, for example, within a few seconds as shown in FIG. Power consumption can also be reduced. Further, the limitation on the number of segments, the reduction in refresh rate, and intermittent display may be combined. For LCDs with a backlight, transflective liquid crystal is used, and the backlight is used only for a part of the normal mode, including part of the normal mode or part of the operation. Turn on the light. Then, during the period of the standby mode, the backlight may be turned off and the power consumption may be suppressed together with the low power consumption display method described above. These controls are performed by the control unit 21.

  In the standby mode, other configurations of the remote control device 2 may be switched so as to reduce power consumption.

  Next, the operation of the remote control system 100 will be described. When the user operates the operation unit 25 of the remote control device 2, the operation unit 25 sends an operation signal corresponding to the operation to the control unit 21. When receiving the signal, control unit 21 switches the operation mode of remote control device 2 from the standby mode to the normal mode. Then, the control unit 21 creates transmission data to be transmitted to the electric device control unit 1 based on the information input by the operation unit 25, and transmits the transmission data from the transmission / reception unit 22 via the antenna 24.

  The transmission data transmitted at this time is composed of a transition signal and a communication frame as shown in FIG. The transition signal is a signal for shifting the operation mode of the electric device control unit 1 from the standby mode to the normal mode. The communication frame is data for causing the electric device control unit 1 to perform an operation corresponding to the information input from the operation unit 25.

  In the standby mode, the transmission / reception unit 12 is not operating and cannot receive a communication frame. The radio wave detector 13 can detect a transition signal even in the standby mode.

  The reception sensitivity of the radio wave detection unit 13 is lower than the reception sensitivity of the transmission / reception unit 12 in the normal mode. Therefore, the transition signal transmitted from the remote control device 2 needs to have a sufficient signal strength to be detected by the radio wave detection unit 13. Therefore, the signal strength of the transition signal is set to a level (for example, several times) higher than the communication frame.

  When the electrical device control unit 1 receives the transition signal by the antenna 14, the radio signal detection unit 13 filters the transition signal at a predetermined frequency, then rectifies and smoothes it by a multistage detection circuit, and then the DC voltage by the rectification circuit. Convert to This is amplified to a predetermined level by an amplifier. Then, it is determined whether or not the amplified signal has a signal level equal to or higher than a predetermined level by a voltage comparator. If the signal level is equal to or higher than a predetermined level, it is input to the control unit 11 as a transition trigger signal. The transition trigger signal is input to an interrupt terminal, for example. When this signal is input, the control unit 11 switches the transmission / reception unit 12 from the standby mode to the normal mode.

  The remote control device 2 transmits a communication frame at a predetermined signal level after a predetermined time (time for the electric device control unit 1 to switch from the standby mode to the normal mode) elapses after the transition signal is transmitted. This transmission level is determined by the reception sensitivity of the transmission / reception unit 12 and the distance between the remote control device 2 and the electrical device.

  When the communication frame is received by the antenna 14 of the electric equipment control unit 1, the communication frame is converted into an electric signal by the transmission / reception unit 12 and input to the control unit 11 as control information. The control unit 11 controls the function of the electric device main body based on the input control information.

  Thus, before transmitting the communication frame for controlling the function of the electric device main body from the remote control device 2, the transition signal having a signal strength stronger than that of the communication frame is transmitted, so the operation mode of the electric device control unit 1 is set. It can be switched appropriately. Moreover, since the electric equipment control part 1 can be set as standby mode until it receives a transition signal, it can reduce power consumption.

  Next, an operation when the control state of the electric device acquired by the electric device control unit 1 is displayed on the remote control device 2 will be described. An electrical device that is activated by a radio signal from the remote control device 2 and receives predetermined control information is controlled by a control state (for example, an operation state (for example, an operation mode such as cooling or heating for an air conditioner) or an operation target value ( For example, the set temperature etc.) is changed.

  The control unit 11 monitors this control state. When the state changes, the control unit 11 switches the operation mode from the standby mode to the normal mode, generates transmission data corresponding to the information, and transmits the transmission data as a radio signal by the transmission / reception unit 12.

  The remote controller 2 switches the operation mode from the normal mode to the standby mode in order to reduce power consumption after a predetermined period (for example, several seconds to several tens of seconds) immediately after the operation. This control is performed by the control unit 21.

  When transmitting information to the remote control device 2 in the standby mode, the control unit 11 transmits a transition signal using the transmission / reception unit 12 in the same manner as the procedure for transmitting a signal from the remote control device 2 to the electrical device control unit 1. After the elapse of time, a radio signal including information is transmitted from the antenna 14. Thereafter, the procedure until the control unit 21 of the remote control device 2 receives the information is the same as that of the electric device control unit 1, and thus the description thereof is omitted.

  Based on the information received from the electrical device control unit 1, the control unit 21 displays on the display unit 26 the control state of the electrical device acquired by the electrical device control unit 1. The control unit 21 switches the transmission / reception unit 22 and the like to the standby mode immediately after the information is received to reduce power consumption.

  As described above, in the first embodiment, the electric device control unit 1 and the remote control device 2 can be set in a standby state in which signals can be constantly received, and can be switched to the normal mode as necessary. . As a result, the battery life can be extended while displaying on the remote control device 2 appropriately. Furthermore, bidirectional and real-time information exchange between the electric equipment control unit 1 and the remote control device 2 can be realized.

Embodiment 2. FIG.
A configuration example of remote control system 200 according to Embodiment 2 of the present invention is shown in FIG. Note that the same reference numerals in the second embodiment denote the same parts as those in the first embodiment, and a description thereof will be omitted. As shown in FIG. 5, the electric device control unit 41 of the second embodiment is different from the electric device control unit 1 of the first embodiment in that a sensor 17 is provided.

  The sensor 17 is a sensor that detects, for example, temperature, radiant heat, humidity, CO2, odor, brightness, illuminance, presence of people, acceleration, and the like. The sensor 17 sends the detected information to the control unit 11.

  The remote control device 42 according to the second embodiment is different from the remote control device 2 according to the first embodiment in that a sensor 28 is provided.

  The sensor 28 is a sensor that detects, for example, temperature, radiant heat, humidity, CO2, odor, brightness, illuminance, presence / absence, acceleration, and the like. The sensor 28 sends the detected information to the control unit 21.

  The operation of the remote control system 200 will be described. Here, the case where the room air conditioner 3 shown in FIG. 6 is used as an electric device will be described. The sensor 28 will be described as a triaxial acceleration sensor.

  When the user lifts the remote control device 42 for any operation or information browsing, the sensor 28 outputs an interrupt signal to the control unit 21 when the acceleration or angle at the time of lifting exceeds a predetermined threshold. .

  When detecting a signal from the sensor 28, the control unit 21 switches the operation mode from the standby mode to the normal mode. Then, the control unit 21 creates monitor command transmission data for monitoring the latest state of the electrical device control unit 41, and transmits a radio signal from the transmission / reception unit 22 via the antenna 24.

  The transmission data at this time is the same as in the first embodiment, and is composed of a transition signal and a communication frame as shown in FIG. A monitor command is transmitted as a communication frame. The operation when the electric equipment control unit 41 that has received the transition signal switches the operation mode from the standby mode to the normal mode is the same as that in the first embodiment.

  When determining that the communication frame is a monitor command, the control unit 11 of the electrical device control unit 41 creates transmission data corresponding to the current control state of the electrical device, and transmits a radio signal from the antenna 14 via the transmission / reception unit 12. Send it out. The remote control device 42 receives the radio signal by the antenna 24, demodulates the signal by the transmission / reception unit 22, and inputs it to the control unit 21.

  Based on the received information, the control unit 21 displays the control state of the electrical device on the display unit 26. The control unit 21 switches the transmission / reception unit 22 and the like to the standby mode immediately after receiving the information to reduce power consumption. Further, the display unit 26 is appropriately switched to low power consumption.

  Next, an operation when displaying information detected by the sensor 17 of the electric device control unit 41 on the remote control device 42 will be described. Here, description will be made assuming that the sensor 17 is a radiant heat sensor mounted on the room air conditioner 3.

  The sensor 17 measures the temperature of a wall surface or a floor, for example. For example, when it is detected that a specific wall surface is hotter than other parts, a scene is assumed where the western sun enters the room and heats the wall surface. In this case, since the heat load can be reduced by closing the curtain or the like, when the electric device is the room air conditioner 3 or the like, it leads to energy saving.

  Since it is necessary for the user to perform actions such as closing the curtain, it is necessary to display this information on the remote control device 42 in order for the user to recognize this.

  When the sensor 17 detects that the specific wall surface is at a higher temperature than other parts, the control unit 11 switches the operation mode from the standby mode to the normal mode, and generates transmission data indicating that, The transmission / reception unit 12 transmits the radio signal.

  Since the procedure until the control unit 21 of the remote control device 42 receives information is the same as that of the electric device control unit 41 of the electric device, the description thereof is omitted.

  Based on the received information, the control unit 21 uses the information detected by the electric device control unit 41 of the electric device on the display unit 26 as a specific action to be taken by the user and its effect. Is displayed. The control unit 21 switches the transmission / reception unit 22 and the like to the standby mode immediately after the information is received to reduce power consumption.

  As described above, in the second embodiment, detection information of sensors mounted on both sides can be reflected in real time, and control such as energy saving control can be expanded. In addition, although an example of an individual room air conditioner has been described, the same effect can be obtained even when applied to a multi air conditioner or an air conditioner using water as a heat medium.

  Next, as a specific application example of the remote control systems 100 and 200 of the above embodiment, a case where the remote control system 100 and 200 is applied to the television 4 will be described.

When the user presses a power-on button, for example, on the operation unit 25 of the remote controller 2 or 42, a sequence transition signal shown in FIG. 2 and a power-on signal (communication frame) are transmitted. Upon receiving the transition signal, the electric device control unit 1 or 41 of the television 4 switches the operation mode from the standby mode to the normal mode, and operates the television 4 based on the power ON signal.

  In addition, when the television 4 receives various types of information (for example, disaster information such as earthquakes and tsunamis) that can be detected by the television 4, for example, the electric device control unit 1 or 41 of the television 4 is based on a similar sequence. By transmitting the received radio signal, the detected information can be displayed on the display unit 26 of the remote control device 2.

  As described above, when the television 4 is operated by the remote control device 2 or 42, it is not necessary to always wait for a command such as turning on the television, and standby power can be reduced. In addition, information detected by the television 4 can be transmitted to the remote control device 2 or 42 in real time and provided to the user. In this case, it is not necessary for the remote control device 2 or 42 to be in a standby state for constantly receiving information, and standby power can be suppressed and battery life can be extended.
