However, the inventive concept may be embodied in many different forms and should not be construed as being limited to the illustrative embodiments set forth herein. In addition, the same reference numerals may be used in the drawings to indicate similar elements.

[Embodiment of Remote Control System]

1 is a functional block diagram of a remote control system according to an embodiment of the present invention. The remote control system provided by the embodiment of the present invention includes a remote controller 10 and an electrical device 20, and the remote controller 10 can remotely remotely control many different types or types of electrical devices 20, such as televisions, video players, air conditioners, electric fans, and the like. Suitable for remote control related equipment. It should be noted that the remote controller of the embodiment can control the operation of the electrical device, and can also sound according to the control signal output by the electrical device. Therefore, so that the relevant personnel can know the location of the remote controller based on this, the relevant description will be explained later.

Referring to FIG. 1 , the electrical device 20 includes a wireless transmitting module 201 , a control module 203 , and a triggering interface 205 . The control module 203 is coupled between the triggering interface 205 and the wireless transmitting module 201 . The trigger interface 205 is, for example, a remote control seek button on a television. When the trigger interface 205 is activated, the control module 203 generates a signal for controlling the remote controller and transmits it to the wireless transmitting module 201. In the embodiment of the present invention, the control signal transmitted by the wireless transmitting module 201 is, for example, a synchronization signal and/or a seek signal, and is received by the remote controller 10.

In the embodiment of the present invention, the remote controller 10 does not need to receive the control signal of the electrical device 20 from time to time. Specifically, the control module 103 of the remote controller 10 can control the opening of the wireless receiving module, especially periodically, for example, the wireless receiving module is turned on every 1 second time period, and the time length of 0.005 seconds is turned on to receive the electrical appliance. The signal sent by device 20. That is to say, the remote controller embodiment of the present invention does not receive signals in a continuously on state. Since the length of time for receiving the signal by the wireless receiving module of the remote controller directly affects the power consumption of the remote controller, the embodiment of the present invention provides that the battery power of the remote controller can be effectively reduced by periodically turning on the remote controller for a short period of time. Consumption.

In addition, the remote controller of the present invention can automatically confirm and communicate the opening time of the electrical device in addition to the wireless transceiver module of the present invention. For example, when the remote controller 10 replaces a new battery or detects that the power supply starts to supply power, or the control module 103 does not complete or confirms synchronization with the electrical device 20, the remote controller 10 continues to the wireless receiving module. 101. The control module 103 and the reminder module 105 are powered for a short period of time, for example, 2 seconds. It should be noted that the synchronization time described herein refers to a time period in which the remote controller 10 turns on the wireless receiving module 101 to receive the signal sent by the electrical device 20, for example, if the wireless receiving module 101 receives the synchronous signal indicating the remote control. The interval between the device 10 and the electrical device 20 for periodic communication is 1 second, and the control module 103 further performs the synchronization time. set up. When the remote controller 10 completes the synchronization time setting with the electrical device 20 or confirms receipt of the synchronization signal at the periodic interval, the other components are turned off, and only the control module 103 continues to be powered. The control module 103 turns on the wireless receiving module 101 for a short period of time (for example, 0.005 seconds) every 1 second, and the remote controller 10 receives the control signal from the electrical device 20 only for a short period of time. That is to say, after the controller 10 and the electrical device 20 are synchronously set, they only need to be turned on for a set period of time, and simultaneously send or receive signals to confirm that the communication cycle of each other's signal transmission is consistent. In this way, the remote controller 10 does not need to continuously consume power for transmitting signals by the electrical device 20 in order to receive an unknown time point. This synchronous manner of turning on the remote controller 10 and the electrical device 20 saves power consumption of the remote controller 10.

Again, in the embodiment of the above-mentioned remote control system that does not use the synchronization signal, in the case that the electrical device 20 does not use the synchronization signal, the control module 103 only turns on the wireless receiving module every one second time period. For a short period of time (e.g., 0.005 seconds), the remote controller 10 will only receive signals from the electrical device 20 during this period of time. At this time, the electrical device 20 needs to repeatedly transmit the search signal, for example, a period of time plus two transmission signals (ie, 1.01 seconds) to ensure that the remote controller 10 can correctly receive the signal correctly. Under such a design, the remote controller 10 only needs to be turned on for 0.005 seconds per second, at which time the power consumption of the remote controller 10 is one-hundredth of the power consumption when the remote controller is continuously turned on.

[Circuit Embodiment of Remote Control and Electrical Apparatus]

2 is a more detailed functional block diagram of a remote controller and an electrical device according to another embodiment of the present invention. Referring to FIG. 2 , the electrical device 20 includes a wireless transmitting module 201 , a control module 203 , and a trigger interface 205 . Incidentally, since the same reference numerals denote the same elements, similar elements and numbers in FIG. 2 are referred to the description of FIG. 1, and will not be repeated here. Referring back to FIG. 2, the control module 203 further includes a transmitting controller B1. The transmitting controller B1 is coupled to the interface 205 for transmitting signals to the wireless transmitting module 201. For example, when the trigger interface 205 is triggered, it is like pressing the battery. The remote control seek button on the device 20 transmits a seek signal to the wireless transmitting module 201 and causes the wireless transmitting module 201 to switch to the on state.

The wireless transmitting module 201 includes an encoder B2, a modulator B3, and a transmitter B4. The encoder B2 encodes information such as an identity code in the machine and an electrical device 20 such as an instruction. After receiving the search signal sent by the control module 203, the encoder B2 encodes the original signal together with the identity code of the electrical device 20 and the related instruction for prompting the user, and transmits the original signal to the amplitude modulator B3. The amplitude modulator B3 modulates the amplitude of the original signal according to the amplitude of the amplitude of the modulated signal. The amplitude modulator B3 further processes the original signal received from the encoder B2, converts the original signal into a corresponding transmittable carrier signal, and the amplitude modulator B3 transmits the carrier signal to the transmitter B4. Finally, transmitter B4 sends out the carrier signal. In this embodiment, the carrier signal is transmitted by the piezoelectric ceramic PZ1 in the frequency range of the ultrasonic wave.

Referring to FIG. 2, the remote controller 10 includes a wireless receiving module 101, a control module 103, and a reminder module 105. Similar to the above, similar components and numbers in FIG. 2 are referred to the description of FIG. 1, and will not be repeated here. Referring to FIG. 2, the wireless receiving module 101 of the remote controller 10 further includes a receiver B6 and a demodulator B7. The receiver B6 is configured to receive the carrier signal transmitted by the electrical device 20. The receiver B6 is coupled to the demodulator B7 to further transmit the carrier signal to the demodulator B7. The demodulator B7 is used to demodulate the carrier signal into an original signal. In this embodiment, the carrier signal includes a synchronization signal for synchronizing the remote controller 10 with the electrical device 20. The carrier signal is re-filtered and demodulated by the demodulator B7 and demodulated into the original signal. This original signal will be transmitted to the control module 103 to further obtain a synchronization message or other information.

The control module 103 includes a power controller B5 and a decoder B8. The power controller B5 is coupled to the wireless receiving module 101 for controlling the power supply of the synchronization period or monitoring the battery power of the remote controller 10. After receiving the demodulated original signal from the wireless receiving module 101, the power controller B5 transmits the original signal to the decoder B8, and continuously supplies power to the wireless receiving module 101 and the decoder B8. The decoder B8 is used to decode the content of the original signal. After the decoder B8 decodes the original signal, the remote controller 10 obtains the synchronization packet with the synchronization time information and identifies the identity code of the electrical device 20, and the decoder B8 notifies the power controller B5 to turn on the remote controller 10 at this synchronization time, thereby completing the synchronization between the remote controller 10 and the electrical device 20. set up. Thereafter, the remote controller 10 only needs to be turned on during the synchronization cycle time of the communication, so that the electrical device 20 and the remote controller 10 simultaneously transmit and receive signals, confirming that they are in a normal operating procedure. Also, the remote controller 10 is in a closed state other than the timed on.

Therefore, the remote controller 10 according to the embodiment of the present invention allows the remote controller 10 to monitor whether the electrical device 20 has a transmission signal without excessive power consumption by means of synchronization with the electrical device 20, thereby greatly extending the remote controller. 10 battery power supply life.

In still another embodiment, the carrier signal transmitted by the wireless transmitting module 201 also includes a seek signal for finding a remote controller. For example, when the remote controller 10 exceeds the range in which the receivable electrical device 20 emits a signal, the signal transmitted by the electrical device 20 is not received during the synchronized time period. At this time, the control module 103 notifies the reminder module 105 to issue a reminder signal to notify the user that the remote controller 10 may have exceeded the received signal range. In this embodiment, the remote controller 10 provides different ways of alerting signals. Specifically, the decoder B8 decodes the identity code and the command from the original signal, and after checking the identity code, sends a reminder signal according to the command, for example, the speaker SP emits a different beat to make a sound or is a light-emitting diode. Body D1 emits a flash of different frequencies. The sound can be the sound of the sound set by the music or the user, and the flash can also be a different flash or a long light set by the user. The present invention is not intended to be limited thereto, and any manner that can attract attention can be used as a reminder signal, and those skilled in the art can make different designs according to different situations.

The remote controller 10 of the embodiment of the present invention also includes a reminder function that the power is too low. When the power controller B5 of the remote controller 10 detects that the battery power is insufficient, the control module 103 controls the reminder module 105 to send a reminder signal to remind the user. Similarly to the above, the control module 103 controls the alarm module 105 to generate a reminder signal by decoding the obtained command by the decoder B8, and alerts the user that the power of the remote controller 10 is currently too low. Reminder signal The form may be that the speaker emits a sound or is illuminated by an illuminating indicator, and is set to a suitable prompt sound or a reminder flash in different situations according to the user's use requirements.

In the embodiment of the present invention, the wireless receiving module 101 and the wireless transmitting module 201 are, for example, a wireless radio frequency module, a bluetooth module, or an ultrasonic module. The wireless receiving module 101 can receive the carrier signal of the ultrasonic wave, the Bluetooth signal or the wireless RF signal. For example, the wireless receiving module 101 and the wireless transmitting module 201 may be piezoelectric ceramics that respectively receive or transmit ultrasonic signals by piezoelectric ceramics. Alternatively, the wireless receiving module 101 and the wireless transmitting module 201 are antennas, and respectively receive or transmit electromagnetic wave signals by using an antenna.

[Another circuit embodiment of remote control and electrical equipment]

3 is a functional block diagram of a remote controller and an electrical device according to another embodiment of the present invention. The remote controller 30 includes a wireless receiving module 101, a control module 103, a reminder module 305, and an input/output interface controller B10. The reminder module 305 includes a light emitting diode D2. The remote controller 30 further includes an input/output interface controller B10 and simplifies the speaker SP as compared with the remote controller 10 of the foregoing embodiment. The input/output interface controller B10 is coupled between the receiver B6 and the piezoelectric ceramic PZ2. The input/output interface controller B10 includes an input mode and an output mode. Specifically, the control module 103 operates the remote controller 30 according to an input mode or an output mode. For example, when the control module 103 controls the input/output interface controller B10 to be in the input mode, the input/output interface controller B10 receives the carrier signal transmitted by the electrical device 40, such as an ultrasonic signal, through the piezoelectric ceramic PZ2. The input/output interface controller B10 further transmits a carrier signal to the receiver B6 of the wireless receiving module 101. The analysis and operation of the received signal by the wireless receiving module 101 of the remote controller 30 is similar to the wireless receiving module 101 of the remote controller 10, and will not be described herein. On the other hand, when the decoder B8 decodes the original signal to obtain an instruction to emit a sound, the control module 103 controls the output interface controller B10 to output mode and generates an audible signal. In the output mode, the input/output interface controller obtains the audible signal output by the control module, and the piezoelectric ceramic device performs the audible signal Sounds.

Remote control 30 also includes functionality to monitor battery power. When the power of the remote controller 30 is too low, the control module 103 outputs a reminder signal through the output mode of the output interface controller B10, and the user can set a reminder signal for the low power condition in advance, which is known by the flash frequency or the sound mode. At present, the remote controller 30 is insufficient in power.

The electrical device 40 includes a wireless transmitting module 401, a control module 203, and a trigger interface 205. Similar to the electrical device 20, the same numbered elements have the same function and therefore will not be described again. The wireless transmitting module 401 includes an encoder B2 and a transmitter B9. Compared with the wireless transmitting module 201, the wireless transmitting module 401 simplifies the amplitude modulator B3. The electrical device 40 can be used in a cost effective manner with the remote controller of the present invention. Similarly to the above, when the electrical device 40 is triggered by the trigger interface 205, the encoder B2 encodes information such as the identity code in the machine and the electrical device 40 such as instructions. After receiving the control signal sent by the control module 203, the encoder B2 encodes the original signal together with the identity code of the electrical device 40 and the related instruction for prompting the user, and transmits the original signal to the open key control transmitter. B9. Finally, the critical control transmitter B9 sends a carrier signal. In this embodiment, the carrier signal is transmitted through the piezoelectric ceramic PZ1 in the frequency range of the ultrasonic wave.

It should be noted that the remote control system of this embodiment is the same as the remote control system of the foregoing embodiment, and the received carrier signal may be a seek signal and a synchronization signal, or only include a seek signal. Specifically, the control module 103 receives a setting signal, thereby setting a signal to set the operation mode of the remote controller to be a signal that is only periodically turned on to receive the electrical device, or a synchronization time set by the synchronization signal of the electrical device. Open. In the implementation of the hardware, the setting of the setting signal can be realized by using a jumper or a switch on the circuit of the remote controller. That is to say, the control module 103 of the remote controller 30 can only control the periodic opening of the wireless receiving module without synchronizing with the electrical equipment, or synchronously confirm and communicate with the electrical equipment for the opening time, which are two proposed by the present invention. Different designs. Similar to the above, in the embodiment where the remote control system does not set the synchronization signal, the electrical device 40 sends a carrier signal that only includes the seek signal. When electrical equipment 40 When the search signal is sent, the control module 203 must repeat the transmitted content and the length of the transmission must exceed the cycle time plus the length of time for transmitting the search signal to ensure that the remote controller 30 receives the error to avoid the problem of missing signal reception. Also, the remote controller 30 is in a closed state other than the timed on. In this manner of periodically opening, the remote controller 30 does not need to maintain the open state to receive the signal of the electrical device 40, and the battery life of the remote controller 30 can be increased.

In the present embodiment, the method of performing ultrasonic communication by the piezoelectric ceramics is more cost-effective than transmitting electromagnetic waves by the antenna, and the circuit produced is relatively simple, which also makes the production easy. Moreover, the ultrasonic wave has stable short-distance communication and ample number of channels. Since the application of the ultrasonic wave is small, the usability is increased, and it is not easily interfered by other signals. Here, the second exemplary embodiment proposes a relatively simplified remote controller 30, which can save the cost of manufacturing the remote controller 30 without affecting the synchronization or searching with the electrical device 40.

[Another circuit embodiment of remote control and electrical equipment]

4 is a functional block diagram of a remote controller and an electrical device according to another embodiment of the present invention. The remote controller 50 includes a wireless receiving touch panel 101, a control module 103, and a reminder module 105. The difference between the remote controller 50 and the remote controller 10 is that the receiver B6 of the remote controller 50 is coupled to the antenna E2. In addition, the electrical device 60 includes a wireless transmitting module 401, a control module 203, and a trigger interface 205. The difference between the electrical device 60 and the electrical device 40 is that the wireless transmitting module 401 of the electrical device 60 is coupled to the antenna E1. The remote controller 50 receives the sync signal or the seek signal transmitted by the antenna E1 of the electric device 60 through the antenna E2. In this example, remote control 50 and electrical device 60 transmit and receive carrier signals, ie, radio signals, with antennas E1, E2.

[Embodiment of Search Method of Remote Control]

FIG. 5 is a flow chart showing a method for searching a remote controller according to an embodiment of the present invention. Referring to FIG. 5, the method flowchart illustrates the operation of the remote controller. Powered by the remote control In the initialization phase, for example, replacing the battery, in step S501, the remote controller starts to operate normally, that is, the remote controller starts to determine whether there is a control signal for receiving the electrical device. In step S503, the remote controller is not continuously turned on, but the wireless receiving module is periodically turned on for a short period of time to receive the signal output by the electrical device, for example, the time period of 0.005 seconds is turned on every 1 second to receive the signal. That is to say, compared with the manner of continuously turning on the remote controller, the length of time that the remote controller is opened by the embodiment of the present invention is only two hundredths of the continuous opening of the remote controller. As a result, the battery power of the remote control is not continuously consumed, increasing the life of the remote control battery, and the user no longer needs to replace the battery from time to time.

Next, in step S505, the remote controller determines whether the search signal of the electrical device is received within the time of opening. If no, the process returns to step S503, and the wireless receiving module is turned on for receiving the signal for a predetermined period of time. If yes, in step S507, the control module of the remote controller instructs the reminder module to output a reminder signal according to an instruction in the search signal, for example, by means of sound emitted by the speaker or by means of a flash generated by the LED. . In this way, the user can find the remote controller through the sound or flash emitted by the remote controller, which can be used for hearing or visually impaired users to find the remote controller by flash or sound. Or, in a dark environment, the reminder signal can be used to guide the user, and the current location of the remote control.

[Another embodiment of the method for finding a remote controller]

FIG. 6 is a flow chart showing a method for searching a remote controller according to an embodiment of the present invention. Referring to FIG. 6, the method flowchart illustrates a means for the remote controller to operate the electrical device. The method flow is applicable to a remote control that can be periodically switched. When the remote controller initializes the power supply phase, for example, when the remote controller just replaces the battery, as in step S601, the wireless receiving module of the remote controller opens a period longer than the length of the regular opening to determine whether the wireless output of the electrical device is received. Signal or look for a signal. In step S603a, if the wireless receiving module does not receive the synchronization signal, the remote controller continues to be turned on at the original cycle time and performs routine signal detection and reception. If the wireless receiving module receives the synchronization message No., in step S605a, the control module of the remote controller sets the time synchronization with the electrical device according to the synchronization signal, so that the wireless receiving module of the remote controller can be turned on according to the set synchronization time period.

At the same time, the remote controller also judges whether the search signal is received, as in step S603b. If yes, the control module of the remote controller instructs the reminder module to output a reminder signal according to an instruction in the search signal, for example, by means of a sound emitted by the speaker or by means of a flash generated by the LED, as in step S605b. . If no, the process returns to step S601, and the remote controller continues to open the wireless receiving module in a time period to determine whether a signal is received.

Then, in step A, after the remote controller completes synchronization with the electrical device according to the synchronization signal, the remote controller is turned off at a normal time, and the wireless receiving module is turned on at the cycle time to receive the synchronization signal, as by step S609. If the remote control continuously receives the synchronization signal during the period of opening, it means that there is no problem in the communication between the remote control and the electrical device, then return to step A. If not, the reminder module of the remote controller outputs a reminder signal. In step S613, the reminder signal notifies the user that the synchronization signal is not received, and the synchronization time may be abnormal.

In addition, in step S607, the control module of the remote controller determines whether the battery power is lower than a preset value. If not, return to step A, and the remote controller will routinely turn on and receive the signal. If yes, the remote controller outputs a reminder signal, as in step S613. The reminder signal can be a flash of different frequencies, or a different music or sound, to remind the user that the remote control is not currently in a state in which the electrical device can be operated normally.

In addition, in step S611, for example, when the user cannot find the remote controller, the user can trigger the trigger interface of the electrical device, and the electrical device periodically sends a seek signal for finding the remote controller continuously or periodically. If the remote controller receives the search signal, in step S613, the remote controller will send a reminder signal, and the user can know the current position of the remote controller by the indication of the reminder signal, so that the user can find the remote controller smoothly. If not, return to step A, the remote control is turned off at normal time, and operates according to the open time period.

Thus, the present invention is the remote controller and the method for finding a remote controller according to the above embodiments. The remote controller is turned on at a cycle time and turned off at other times, thereby extending the battery life of the remote controller, reducing the power consumption of the use, and not Affect the usage habits of previous users on remote controls or electrical equipment. Moreover, the remote controller embodiment proposed by the present invention transmits carrier signals by ultrasonic communication, so that the circuit of the remote controller is simple, and the manufacturing cost is cheap, and the production is easier. Due to the application of ultrasonic communication in life, the use space is larger, and the communication between the remote control and the electrical equipment is not easily interfered by other equipment. In addition, the embodiment of the present invention further provides that the user's battery power in the remote controller is too low to remind the user that the user does not wait until the remote controller is exhausted, and the remote controller cannot be used normally. In addition, when the remote controller exceeds the range of the receiving electrical device to send signals, the remote control button on the electrical device can also be used to send a search signal to help the user find the remote controller, and the reminder signal can be set according to the operating conditions of the user in different situations. Such a variety of designs are more in line with the user's habits, such as flashing the user in a dark environment or making a sound when the remote is not found to assist in finding the remote control.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
