Description

  The present invention relates to a remote controller including a control unit.

  As a remote controller, a remote controller used in, for example, an air conditioner has been conventionally proposed. Among such remote controllers, for example, there is one in which a touch panel is provided on a display unit such as a liquid crystal display and a touch panel operation function is mounted. The touch panel is generally provided with a detection coordinate correction mode in order to appropriately correct the detection coordinates. In order to prevent the detected coordinate correction mode from being shifted to the detected coordinate correction mode for the purpose of mischief during normal use, a password consisting of a plurality of numbers or characters is used as a transition condition. Input is required.

  As a technique similar to this, Patent Document 1 discloses a portable terminal device that can be switched from a normal operation mode to a monitoring mode based on information on the surrounding situation. In Patent Document 1, information obtained by, for example, an acceleration sensor or an illuminance sensor is used as information on the surrounding situation.

JP 2011-228872 A (Claims 1, 5 and 6)

  However, when a password is required to enter the detected coordinate correction mode, the detected coordinates of the touch panel may be shifted so much that it is impossible to input the password due to deterioration over time. In this case, even if an attempt is made to input a password using the touch panel, normal input cannot be made and the mode cannot be shifted to the detected coordinate correction mode. For this reason, a part other than the touch panel is normal, and if only the detected coordinates of the touch panel are corrected, there arises a problem that even if the remote controller can be used continuously, the remote controller itself must be replaced.

  Moreover, although the portable terminal device disclosed by patent document 1 is switched from an operation mode to a monitoring mode only by the information obtained by an acceleration sensor or an illuminance sensor, it is based only on the information obtained by these acceleration sensors or an illuminance sensor. If the display state is switched, a state in which the display state is easily switched unintentionally due to a slight change in the situation may occur. As described above, in Patent Document 1, there is a high possibility that a malfunction in switching the display state occurs.

  The present invention has been made against the background of the above problems, and provides a remote controller that does not require a password and suppresses a malfunction in which a display state is switched unintentionally.

  A remote controller according to the present invention detects a brightness, a display unit that displays information, a touch panel that is provided on the front surface of the display unit and that performs an input operation on the display unit, a human detection unit that detects a person, and the like Based on the brightness detection unit, the input result on the touch panel, the detection result on the human detection unit, and the detection result on the brightness detection unit, the display state on the display unit is switched from the normal mode to the management mode for displaying management information. And a control unit.

  According to the present invention, the display state on the display unit is switched from the normal mode to the management mode based on the input result on the touch panel, the detection result on the human detection unit, and the detection result on the brightness detection unit. For this reason, when switching the display state, it is not necessary to input a password, and a malfunction in which the display state is switched unintentionally is suppressed.

Embodiment 1 FIG.
FIG. 1 is a front view showing a remote controller 1 according to the first embodiment. The remote controller 1 will be described with reference to FIG. As shown in FIG. 1, the remote controller 1 is used for an air conditioner, for example, and includes a display unit 2, a touch panel 3, a person detection unit 4, a brightness detection unit 5, an LED 6, and a control. Part 10.

(Display unit 2)
The display part 2 displays each information, such as an air conditioner, and is provided with the liquid crystal panel 2a and the backlight 2b provided in the back surface. The display unit 2 is installed at the center of the remote controller 1, but the installation location may be the edge of the remote controller 1. Moreover, the magnitude | size can be changed suitably.

(Touch panel 3)
The touch panel 3 is provided on the front surface of the display unit 2 and an input operation to the display unit 2 is performed. By touching the numbers or characters displayed on the display unit 2 via the touch panel 3, information on the contacted part is reflected in the remote controller 1.

(Human detection unit 4)
The person detection unit 4 detects a person and can be, for example, a human sensor. The human detection unit 4 is provided at the upper part and the side part of the remote controller 1, but the installation location may be the lower part of the remote controller 1 and is not particularly limited. Moreover, the magnitude | size can be changed suitably.

(Brightness detection unit 5)
The brightness detection unit 5 detects brightness and can be, for example, an illuminance sensor. The brightness detection unit 5 is installed in the upper part of the remote controller 1 and in the vicinity of the human detection unit 4, but the installation location may be in the lower part of the remote controller 1 or in the side part. Further, it is not necessary to be in the vicinity of the human detection unit 4. Further, the size can be changed as appropriate.

(LED6)
The LED 6 is a light emitting element that emits light when a voltage is applied. Although this LED 6 is provided in the lower part of the remote controller 1, the installation place may be the upper part of the remote controller 1 or a side part. Moreover, the magnitude | size can be changed suitably.

(Control unit 10)
Based on the input result on the touch panel 3, the detection result on the human detection unit 4, and the detection result on the brightness detection unit 5, the control unit 10 displays management information from the normal mode on the display state on the display unit 2. Switch to mode. In the normal mode, normal input on the touch panel 3 is performed. Further, as an example of the management mode, there is a detection coordinate correction mode, and this detection coordinate correction mode is for correcting the detection coordinates on the touch panel 3. In this case, the control unit 10 switches from the normal mode to the detected coordinate correction mode based on the input result on the touch panel 3, the detection result on the human detection unit 4, and the detection result on the brightness detection unit 5.

  FIG. 2 is a block diagram illustrating the control unit 10 according to the first embodiment. As shown in FIG. 2, the control unit 10 includes a person determination unit 11, an input determination unit 12, a brightness determination unit 13, and a pattern determination unit 14.

(Person determination means 11)
The person determination unit 11 determines whether or not the person detection unit 4 detects that there is no person. When the person determination unit 11 determines that there is no person, the person determination unit 11 transmits a signal including information that there is no person to the input determination unit 12.

(Input determination means 12)
The input determination unit 12 determines whether or not an input on the touch panel 3 has been performed. If the input determination unit 12 determines that an input has been made on the touch panel 3, the input determination unit 12 transmits a signal including information indicating that the input has been made to the brightness determination unit 13.

(Brightness determination means 13)
The brightness determination means 13 determines whether the brightness detected by the brightness detection unit 5 is equal to or greater than a predetermined brightness threshold. The determination result in the brightness determination unit 13 includes, for example, a bright state in which the brightness detected by the brightness detection unit 5 is equal to or greater than the brightness threshold, and the brightness detected by the brightness detection unit 5 is the brightness threshold. It is possible to obtain a light / dark pattern that is a combination with a dark state that is less than. If it is determined by the person determination means 11 that there is no person and the input determination means 12 determines that an input has been made, the process proceeds to a light / dark pattern input acceptance mode. And in this light / dark pattern input reception mode, it will be in the state which waits for the input of a light / dark pattern.

  The light / dark pattern is a combination of a light state and a dark state for each predetermined time. FIG. 3 is a timing chart showing the operation of the remote controller 1 according to the first embodiment. As shown in FIG. 3, it is determined that the person determination unit 11 determines that there is no person and the input determination unit 12 determines that an input has been performed, and then a light / dark pattern is acquired. One second after the time measurement is started, the brightness determination means 13 determines whether the light state is in effect. This is the first time. This is repeated four times, and the brightness determination means 13 performs determination each time in the first, second, third and fourth times.

The light / dark pattern is a combination of these four bright and dark states. FIG. 3 illustrates a light / dark pattern of the first time: dark state, the second time: dark state, the third time: bright state, and the fourth time: dark state. The brightness determination unit 13 transmits a signal including these light and dark patterns to the pattern determination unit 14.

The brightness determination unit 13 is configured to transmit a signal including this information to the pattern determination unit 14 when it is determined that the brightness detected by the brightness detection unit 5 is equal to or greater than the brightness threshold. May be. In this case, the light / dark pattern which is the determination result in the brightness determination means 13 is only in the first time: dark state.

(Pattern determination means 14)
The pattern determination unit 14 compares the determination result in the brightness determination unit 13 with a predetermined brightness reference pattern. More specifically, the pattern determination unit 14 determines that the brightness detected by the brightness detection unit 5 is greater than or equal to the brightness threshold and the brightness detected by the brightness detection unit 5 is less than the brightness threshold. A light / dark pattern which is a combination with a certain dark state is compared with a brightness reference pattern. Note that the brightness reference pattern is a combination of a bright state and a dark state four times in total. In the first embodiment, the brightness reference pattern is as follows: first time: dark state, second time: dark state, third time: bright state, fourth time: dark state.

  Then, when the pattern determination unit 14 determines that the determination result in the brightness determination unit 13, that is, the light / dark pattern and the brightness reference pattern match, information that the light / dark pattern matches the brightness reference pattern is displayed. The included signal is transmitted to the display unit 2. As a result, the display state of the display unit 2 is switched from the normal mode to the detected coordinate correction mode.

  Next, the operation of the remote controller 1 according to the first embodiment will be described. FIG. 4 is a flowchart showing the operation of the remote controller 1 according to the first embodiment. As shown in FIG. 4, when the control of the remote controller 1 is started, first, the person determination unit 11 determines whether or not the person detection unit 4 detects that no person is present (step S1). When it is determined by the person determination means 11 that there is a person (No in step S1), the process returns to step S1 again. On the other hand, when it is determined by the person determination means 11 that there is no person (Yes in step S1), the process proceeds to step S2.

  In step S <b> 2, the input determination unit 12 determines whether or not an input on the touch panel 3 has been performed. If the input determination means 12 determines that no input has been made (no input) (No in step S2), the process returns to step S1. On the other hand, when the input determination means 12 determines that an input has been made (input is present) (Yes in step S2), the process proceeds to a light / dark pattern input acceptance mode (step S3).

  In step S3, a determination result obtained by the brightness determination unit 13, that is, a light / dark pattern is acquired. Thereafter, the light / dark pattern and the brightness reference pattern are compared by the pattern determination means 14 (step S4). Note that switching between the bright state and the dark state in the light / dark pattern is performed by, for example, the user operating the remote controller 1 covering the brightness detection unit 5 with a finger. In this case, the bright state is obtained by exposing the brightness detection unit 5, and the dark state is obtained by covering the brightness detection unit 5 with a finger.

  When the pattern determination unit 14 determines that the light / dark pattern is different from the brightness reference pattern (No in step S4), the process returns to step S1. On the other hand, when the pattern determination unit 14 determines that the light / dark pattern matches the brightness reference pattern (Yes in step S4), the normal mode is shifted to the detected coordinate correction mode (step S5). When the detected coordinates on the touch panel 3 are corrected in the detected coordinate correction mode, the processing is completed and the normal mode is restored.

  As described above, in the remote controller 1, the display state on the display unit 2 is switched based on the input result on the touch panel 3, the detection result on the human detection unit 4, and the detection result on the brightness detection unit 5. For this reason, it is not necessary to input a password when switching the display state.

  That is, the first embodiment shifts to the detected coordinate correction mode without inputting a password even if the detected coordinates of the touch panel 3 are shifted so that normal input by the touch panel 3 is impossible due to deterioration over time. can do. For this reason, if the remote controller 1 can be used continuously as long as the parts other than the touch panel 3 are normal and only the detected coordinates of the touch panel 3 are corrected, the detected coordinates are corrected in the detected coordinate correction mode. The remote controller 1 itself can be used continuously without replacing the product.

  Further, since the display state is switched based on three pieces of information, that is, an input result on the touch panel 3, a detection result on the human detection unit 4, and a detection result on the brightness detection unit 5, the display state is not intended. The malfunction which switches is suppressed. On the other hand, for example, if the display state in the display unit 2 is switched based only on the illuminance information such as the illuminance sensor, the display is easily and unintentionally displayed depending on the brightness of the room where the remote controller 1 is used. A state in which the state is switched occurs.

  In the first embodiment, when the person determination unit 11 determines that there is no person, the person determination unit 11 transmits a signal including information that there is no person to the input determination unit 12. If the input determination unit 12 determines that an input has been made on the touch panel 3, the input determination unit 12 transmits a signal including information indicating that the input has been made to the brightness determination unit 13. As a result, the process shifts to the light / dark pattern input acceptance mode.

  Usually, when an input is performed by the touch panel 3, there is a person near the remote controller 1 on which the touch panel 3 is mounted. The present embodiment 1 intentionally creates a situation that cannot occur during normal use in which input is performed by the touch panel 3 even when there is no person, and only in this situation is the mode shifted to the light / dark pattern input acceptance mode. It is configured. Thereby, the malfunction which a display state switches unintentionally can be suppressed more.

  As described above, when the input determination unit 12 determines that the input on the touch panel 3 has been performed, the input determination unit 12 transmits a signal including information indicating that the input has been performed to the brightness determination unit 13. The information that the information has been broken may include coordinate data, or the coordinate data may be omitted.

Embodiment 2. FIG.
Next, the remote controller 100 according to Embodiment 2 will be described. FIG. 5 is a timing chart showing the operation of the remote controller 100 according to the second embodiment. The second embodiment is different from the first embodiment in that the notification unit 7 notifies the timing of changing the determination result in the brightness determination means 13 to a bright state and a dark state. In the second embodiment, portions common to the first embodiment are denoted by the same reference numerals, description thereof is omitted, and differences from the first embodiment will be mainly described.

  In the second embodiment, the LED 6 provided in the remote controller 100 is used as the notification unit 7. As shown in FIG. 5, it is determined that the person determination unit 11 determines that there is no person and the input determination unit 12 determines that an input has been performed, and then a light / dark pattern is acquired. After the time measurement is started, the LED 6 notifies the timing of changing the determination result in the brightness determination means 13 to the bright state and the dark state.

  Specifically, the LED 6 is lit for 0.2 seconds after 0.2 seconds after the time measurement is started. Then, the user operating the remote controller 100 can know the first timing for selecting whether to expose the brightness detection unit 5 or cover it with a finger by turning on the LED 6. This is repeated four times, and the LED 6 is lit for 0.2 seconds at the first time, the second time, the third time, and the fourth time, respectively.

  The lighting time and the light-off time can be selected as appropriate, and may be 0.5 seconds and 0.5 seconds, respectively. Moreover, the alerting | reporting part 7 may use the backlight 2b in the display part 2 other than LED6. Furthermore, the display part 2 is good also as a speaker etc., In this case, it alert | reports by emitting a sound.

  Next, the operation of the remote controller 100 according to the second embodiment will be described. FIG. 6 is a flowchart showing the operation of the remote controller 100 according to the second embodiment. As shown in FIG. 6, when the control of the remote controller 100 is started, first, it is determined by the person determination means 11 whether or not the person detection unit 4 has detected that there is no person (step S11). When it is determined by the person determination means 11 that there is a person (No in step S11), the process returns to step S11 again. On the other hand, when it is determined by the person determination means 11 that there is no person (Yes in step S11), the process proceeds to step S12.

  In step S <b> 12, the input determination unit 12 determines whether or not an input on the touch panel 3 has been performed. If the input determination means 12 determines that no input has been made (no input) (No in step S12), the process returns to step S11. On the other hand, when it is determined by the input determination means 12 that an input has been made (input is present) (Yes in step S12), the process proceeds to a light / dark pattern input acceptance mode (step S13).

  Then, in step S14, the timing of the bright state and the dark state is notified by turning on and off the LED 6. In step S14, a determination result obtained by the brightness determination unit 13, that is, a light / dark pattern is acquired. Thereafter, the pattern determination means 14 compares the light / dark pattern with the brightness reference pattern (step S15).

  If the pattern determination unit 14 determines that the light / dark pattern is different from the brightness reference pattern (No in step S15), the process returns to step S11. On the other hand, when the pattern determination unit 14 determines that the light / dark pattern matches the brightness reference pattern (Yes in step S15), the normal mode is shifted to the detected coordinate correction mode (step S16). When the detected coordinates on the touch panel 3 are corrected in the detected coordinate correction mode, the processing is completed and the normal mode is restored.

  As described above, in the second embodiment, the notification unit 7 notifies the timing when the determination result in the brightness determination unit 13 is changed to the bright state and the dark state. For this reason, the user who operates the remote controller 100 can easily recognize the timing for selecting the bright state and the dark state in the brightness detection unit 5. Therefore, the second embodiment has an effect that the usability of the remote controller 100 is improved in addition to the effect obtained in the first embodiment.
