Also, when using ultrasonic waves, the data compression ratio can be made higher than when using sound waves in the audible range.

FIG. 2 is a diagram showing the functional configuration of the remote controller 100 shown in FIG. 1. As shown in FIG. The remote controller 100 has a sound wave communication section 110 and a control section 140 . The sonic wave communication unit 110 has a sonic wave receiving unit 120 and a sonic wave transmitting unit 130 .

The sonic communication unit 110 performs sonic communication using sonic signals with the mobile terminal 200 .

FIG. 3 is a diagram showing an example of a hardware configuration for realizing the functions of the remote controller 100 shown in FIG. 2. As shown in FIG.

The functions of the sound wave communication unit 110 of the remote controller 100 include a sound collector 121, an A/D (Analog/Digital) conversion circuit 122, a filter circuit 123, an envelope detection circuit 124, and a D/A (Digital/Analog) conversion circuit 131. , the sound generator 132 . Among these components, the sound collector 121 , the A/D conversion circuit 122 , the filter circuit 123 , and the envelope detection circuit 124 are used to realize the function of the sound wave receiving section 120 . Among these components, the D/A conversion circuit 131 and the sound generator 132 are used to implement the function of the sound wave transmission section 130 . The functions of the control section 140 of the remote controller 100 can be implemented using an MCU (Micro Controller Unit) 141 .

The sound collector 121 is a sound collector that outputs ambient sound waves as analog values. The sound collector 121 is, for example, a microphone module. An analog value output by the sound collector 121 is input to the A/D conversion circuit 122 and the filter circuit 123 . The A/D conversion circuit 122 converts the input analog value into a digital value and outputs the digital value. A digital value output from the A/D conversion circuit 122 is input to port a of the MCU 141 . Port a is the first port through which the MCU 141 takes in the output signal of the A/D conversion circuit 122, and the number of ports need not be one.

The filter circuit 123 filters analog values input from the sound collector 121 in a predetermined frequency band. The envelope detection circuit 124 extracts the envelope included in the output waveform of the filter circuit 123 with an arbitrary threshold value. The output of envelope detection circuit 124 is input to port b of MCU 141 . A port b is a second port for the MCU 141 to receive a start signal. The start signal is a signal transmitted at a predetermined frequency and timing between the mobile terminal 200 and the remote controller 100. The start signal is transmitted before starting communication of transmission data and indicates the start of communication. .

Filter circuit 123 and envelope detection circuit 124 are set so that the start signal can pass. The passband, which is the frequency band passed by the filter circuit 123, is determined in advance based on the use band of the start signal. The filter circuit 123 passes signals in the passband including the band used for the start signal, and cuts off signals outside the passband. Filter circuit 123 and envelope detection circuit 124 are also called start signal detection section 125 . The start signal detector 125 extracts the start signal from the analog value output by the sound collector 121 and inputs it to the port b of the MCU 141 .

With the sound wave receiving unit 120 configured as described above, the port a of the MCU 141 always receives the digital value of the sound wave signal from the A/D conversion circuit 122, and the port b of the MCU 141 receives the sound wave receiving unit 120. If the received sound wave signal contains the start signal, the start signal is input.

The D/A conversion circuit 131 converts the digital value of transmission data input from the port c of the MCU 141 into an analog value and outputs the analog value. Port c is a third port for the MCU 141 to output transmission data to the sound wave transmitter 130 . An analog value output from the D/A conversion circuit 131 is input to the sound generator 132 . The sound generator 132 is a speaker module or the like that sounds the input analog value as a sound wave to the surroundings. The sound generator 132 includes an audio circuit (not shown) such as an amplifier circuit.

The MCU 141 has a function of analyzing the frequency of the sound wave signal input from the sound wave receiving section 120 . The MCU 141 sets the controlled device according to the analysis result. The MCU 141 also generates and outputs transmission data for generating a sound wave signal to be transmitted from the sound wave transmission unit 130 . For example, when the sound wave signal input from the sound wave receiving unit 120 includes a request signal requesting the current setting value of the control target device, the MCU 141 generates transmission data including the requested setting value, and sends it to the port c. Output from The MCU 141 can transmit transmission data including setting values of the control target device to the mobile terminal 200 using sound wave signals.

4 is a diagram showing an output waveform of the sound collector 121 shown in FIG. 3 and an input waveform of the MCU 141. FIG. FIG. 4 shows the output waveform of the sound collector 121, the input waveform to the port a of the MCU 141, and the input waveform to the port b of the MCU 141. FIG. A sound wave signal is transmitted from the portable terminal 200 to the remote controller 100 during the period T1s to T4, and is captured by the sound collector 121 of the remote controller 100. FIG.

Here, a start signal indicating the start of sound wave communication is input to the sound collector 121 from T1s to T3e of the period T1s to T4. During periods T3e to T4 of periods T1s to T4, signals indicating data contents such as set values and requests for set values are input to the sound collector 121 . Note that the start signal may be transmitted multiple times in order to improve noise immunity. In the diagram shown in FIG. 4, the start signal is transmitted three times.

The analog value of the sound wave signal output by the sound collector 121 is converted into a digital value by the A/D conversion circuit 122 and is constantly input to the port a of the MCU 141 .

Also, the analog value of the sound wave signal output by the sound collector 121 is branched at the stage preceding the A/D conversion circuit 122 and input to the port b of the MCU 141 via the start signal detector 125 . The passband of the filter circuit 123 may pass the frequency of the start signal, and may or may not pass the frequency used for data transmission. In the example shown in FIG. 4, the passband of filter circuit 123 is set to block frequencies used for data transmission.

When the signal input to port b matches a known start signal, that is, when the start signal detector 125 detects the start signal, the MCU 141 starts frequency analysis processing of the sound wave signal. In other words, the MCU 141 stops the frequency analysis processing of the sound wave signal until the start signal is detected. If setting data is included in the sound wave signal as a result of the frequency analysis processing, the MCU 141 sets at least one of the remote controller 100 and the device to be controlled according to the analysis result. Further, when the sound wave signal contains the request signal from the mobile terminal 200 as a result of the frequency analysis processing, the MCU 141 generates transmission data including the setting value indicated by the request signal, outputs the transmission data to the port c, and transmits the sound wave. The data is transmitted from the unit 130 to the mobile terminal 200 .

FIG. 5 is a diagram showing a functional configuration of mobile terminal 200 shown in FIG. Portable terminal 200 includes sound wave communication section 210 , control section 240 , and display operation section 250 . The sonic wave communication unit 210 has a sonic wave receiving unit 220 and a sonic wave transmitting unit 230 .

The sonic communication unit 210 performs sonic communication using sonic signals with the remote controller 100 . The sound wave receiving unit 220 receives the sound wave signal transmitted by the remote controller 100 and inputs the received sound wave signal to the control unit 240 . The sound wave transmission unit 230 generates sound wave signals obtained by frequency-converting carrier sound waves based on transmission data input from the control unit 240, and transmits the generated sound wave signals.

When the sound wave receiving unit 220 receives the sound wave signal, the control unit 240 interprets the received sound wave signal and restores the transmission data. If the restored transmission data includes setting values for at least one of the remote controller 100 and the controlled device, the control unit 240 can display the setting values on the display screen.

The control unit 240 displays a setting screen for accepting settings for at least one of the remote controller 100 and the device to be controlled. When an input is made on the setting screen, the control unit 240 generates transmission data including the setting data input using the setting screen, and inputs the generated transmission data to the sound wave transmission unit 230 .

Display operation unit 250 has a function of displaying a screen generated by control unit 240 and a function of receiving an operation on the displayed screen. The display operation unit 250 is, for example, a touch panel in which a touch sensor is superimposed on a display device.

FIG. 6 is a diagram showing an example of a setting screen displayed by mobile terminal 200 shown in FIG. The control unit 240 can use the display operation unit 250 to output the setting screen shown in FIG. Items that can be set using the setting screen include basic settings, display settings, operation settings, energy saving settings, timer/schedule settings, maintenance settings, and service settings.

Also, using this setting screen, the mobile terminal 200 can acquire setting data from the remote controller 100 . When the operator uses the setting screen to perform an operation for acquiring setting data, the control unit 240 generates request data for requesting the remote controller 100 for setting values. The request data includes information indicating items of setting values to be acquired. The request data may also include identification information for identifying the remote controller 100 to which the setting value is requested. The control unit 240 uses the sound wave transmission unit 230 to transmit a request signal, which is a sound wave signal obtained by frequency-converting a carrier sound wave, to the remote controller 100 based on the generated request data.

FIG. 7 is a diagram showing an example of a display setting screen displayed by mobile terminal 200 shown in FIG. The control unit 240 can use the display operation unit 250 to output the display setting screen shown in FIG. The display setting screen is displayed when an operation to select "display setting" on the setting screen shown in FIG. 6 is performed. Items that can be set using the display setting screen include main screen display settings, remote control display settings, language display settings, contrast/brightness adjustment settings, and _CO2 display settings.

Next, the operation of mobile terminal 200 will be described. FIG. 8 is a flowchart showing the operation of mobile terminal 200 shown in FIG. The control unit 240 of the mobile terminal 200 activates the setting application when the operator performs an operation to activate the setting application (step S101).

The control unit 240 displays the setting screen shown in FIG. 6 and accepts the input operation of the operator (step S102). When the operator performs an input operation, the control unit 240 determines whether the input operation instructs transmission of setting data or acquisition of setting data (step S103).

When transmission of setting data is instructed (step S103: transmission), the control unit 240 generates setting data based on the input operation on the setting screen (step S104). When the setting data is input from the control unit 240, the sound wave transmitting unit 230 generates sound wave signals based on the setting data (step S105).

If acquisition of setting data is instructed (Step S103: Acquisition), the control unit 240 generates request data for specifying items of setting data to be requested based on the input operation on the setting screen (Step S106). When the request data is input from the control unit 240, the sound wave transmission unit 230 generates a sound wave signal based on the request data (step S107).

The sound wave transmission unit 230 transmits the sound wave signal generated in step S105 or step S107 (step S108).

Next, operations of the remote controller 100 will be described. FIG. 9 is a flow chart showing the operation of the remote controller 100 shown in FIG. The control unit 140 of the remote controller 100 determines whether or not the start signal is detected based on the input to the port b (step S201).

When the start signal is detected (step S201: Yes), the control unit 140 starts frequency analysis processing of the sound wave signal (step S202). If the start signal is not detected (step S201: No), the control unit 140 repeats the process of step S201 until the start signal is detected.

The control unit 140 determines whether the analysis result of the frequency analysis process is setting data (step S203). Here, it is assumed that the sound wave signal transmitted from mobile terminal 200 is setting data or request data.

If the analysis result is setting data (step S203: Yes), the control unit 140 performs setting processing for at least one of the controlled device and the remote controller 100 according to the analysis result (step S204).

If the analysis result is request data (step S203: No), the control unit 140 generates transmission data by converting the setting data into sound wave generation data based on the request data (step S205). The sound wave transmitter 230 generates sound wave signals based on the transmission data (step S206). The sound wave transmitter 230 transmits the generated sound wave signal (step S207).

Note that the portable terminal 200 may add a destination to the sound wave signal when it is desired to transmit the transmission data to some of the plurality of remote controllers 100 . In this case, even if the remote controller 100 receives a sound wave signal not addressed to itself, the remote controller 100 does not perform the setting process and the setting data transmission process.

As described above, according to Embodiment 1 of the present invention, remote controller 100 receives setting data from mobile terminal 200, which is an external device, using sound waves, and controls at least one of remote controller 100 and the control target device. can be set to By adopting such a configuration, it is possible to simultaneously transmit setting data to a plurality of remote controllers 100 installed within the reach of sound waves, so that data setting work can be easily performed from the portable terminal 200. . By using sound waves, there is no need to install a communication device such as a router, and there is no need to perform pairing work with each of the plurality of remote controllers 100 one by one. In addition, since the reachable distance of sound waves is longer than the communication distance of short-range wireless communication such as NFC, setting data can be transmitted to the remote controller 100 even from a remote location.

When sound waves in the audible range are used for sound wave communication, the operator can audibly confirm that data is being transmitted or received, and the operator can control the communication between the remote controller 100 and the mobile terminal 200. A communication connection can be easily determined, and a remote controller 100 capable of setting or acquiring data can be easily specified.

When ultrasonic waves are used for sound wave communication, a greater data compression ratio can be achieved compared to sound waves in the audible range. Therefore, it is possible to shorten the time required to acquire or set data.

Further, the remote controller 100 stops the frequency analysis processing of the sound wave signal until the start signal is detected. Therefore, the remote controller 100 stops the frequency analysis process when the mobile terminal 200 does not perform the sound wave communication, thereby reducing the resource consumption of the CPU (Central Processing Unit) provided in the MCU 141. Become.

Also, when detecting a plurality of start signals, the control unit 140 can start the frequency analysis process. That is, the control unit 140 can stop the frequency analysis process until a predetermined number of two or more start signals are detected. In this case, it is possible to prevent the frequency analysis processing from being erroneously started due to noise having the same frequency as the start signal, and it is possible to improve the noise immunity of sound wave communication.

Further, the remote controller 100 has a function of, upon receiving a request signal from the mobile terminal 200, transmitting to the mobile terminal 200 a sound wave signal including the set value of the item indicated by the request signal. With such a configuration, the mobile terminal 200 can acquire the current setting values of the remote controller 100 and the control target device from the remote controller 100 . Therefore, it becomes easy to check the values already set in the remote controller 100 and the controlled device. For example, when performing maintenance/inspection work or responding to inquiries from users who use the controlled device, it is necessary to check the operation of the controlled device and check the current settings as preparatory work before starting actual work. sometimes In the past, preparation work was done by connecting a dedicated maintenance tool or performing complicated operations on a remote controller. On the other hand, by using the remote controller 100 according to the present embodiment, it is possible to acquire the control target device and the values set in the remote controller 100 from the remote controller 100 with a simple operation. Easier preparation work.

Also, the mobile terminal 200 acquires setting values from the set remote controller 100 and the control target device, and transmits the acquired setting values to the other remote controller 100 by sound wave communication, thereby copying the setting values between the devices. be able to Therefore, it is possible to easily set the remote controller 100 and the device to be controlled. For example, when the layout of a building such as an office building is changed, there are cases where it is desired to use the same values as the existing settings when adding remote controllers or rearranging the layout. Conventionally, it was necessary to confirm the existing setting values and input the confirmed setting values into each remote controller. On the other hand, by using the remote controller according to the present embodiment, the portable terminal 200 acquires setting values from the first remote controller 100 that has already been set, and sets them in the second remote controller 100 as they are. It is possible to copy the values or change only some of the setting values before transmitting the setting values to the second remote controller 100 . Such an operation is executed by performing an operation on the screen of the application program installed in the mobile terminal 200. FIG. Therefore, the setting work is facilitated, and setting errors can be suppressed.

Further, in the first embodiment, the sound wave communication used uses sound wave signals obtained by frequency-converting carrier sound waves based on transmission data. Such a sound wave signal uses a predetermined frequency band and transmits data using a known pattern, so it is possible to transmit the transmission data more accurately than voice analysis. In addition, frequency analysis processing on the receiving side has a lower processing load than voice analysis processing.

The configuration shown in the above embodiment shows an example of the content of the present invention, and it is possible to combine it with another known technology, and one configuration can be used without departing from the scope of the present invention. It is also possible to omit or change the part.
