Abstract

PURPOSE:To control plural electronic equipments and to prevent more than two electronic equipments from operating simultaneously by eliminating the operation of learning a key command in a learning remote control device. CONSTITUTION:When a number key 4a is operated, the set position of a mode switching switch 4b is discriminated. Then, the corresponding key command is read out from a ROM 3, and inputted to a transmitting part 5. The transmitting part 5 converts the inputted key command to a remote control signal due to an infrared ray, and transmits it. The transmitted key command is received by a receiving part 11 of an electronic equipment 6 immediately. Then, whether the key command is received or not is judged, the remote control signal of the key command is converted to a digital data signal and outputted to a control part 7. This is stored in a command storing part R1 of an RAM 12 by the control of the control part 7. This process is repeated for each mode.

The key operator section 10 includes a function key 10a and a mode changeover switch 10b. The function keys 10a are used to specify various functions of the TV, and have 12 keys such as "power ON key" and "r channel 1 key". The mode changeover switch 10b is a slide switch that changes over between a "registration mode" and a "search mode," and both modes are switched depending on the slide position of the device.

The receiving unit 11 includes a light receiving element (not shown) such as a photodiode or a phototransistor, and receives the remote control signal transmitted from the remote control device 1 . Then, the receiving section 11 converts the received remote control signal into a digital data signal and outputs it to the control section 7.

The command storage section RI"R- is a storage area in which received key commands are registered corresponding to each function key 10a. That is, the command storage section RI"R- is a storage area in which received key commands are registered in correspondence with each function key 10a. The command is stored in the command storage units R1 to R9 corresponding to the function key 10a being operated at the time.

The control code storage units f, to f, are storage areas in which control codes corresponding to each function key 10a are automatically stored by the control unit 2 when the power is turned on. For example, a control code corresponding to a "power ON key" is stored in the control code storage section f, and a control code corresponding to a "channel 1 key" is stored in the control code storage section f2. In addition, R
Using other memory such as OTP (one-time programmable) ROM instead of AM12, each function key 1
Control codes corresponding to 0a may be stored.

Next, the operation of the first embodiment will be explained.

First, the operation of the remote control device 1 will be explained based on FIG. 4. FIG. 4 is a flowchart showing the operation of the remote control device 1. When the numeric keys 4a of the keypad section 4 are operated, the remote control device 1 starts the process shown in FIG. 4. first,
In step A1, the mode is determined. That is, the setting position of the mode changeover switch 4b is "mode 1" to "mode 4".
Determine which of the following. In the next step A2, the mode determined in step A1 and the key command corresponding to the operated numeric key 4a are read from the ROM 3 and input to the transmitter 5.

Then, the transmitter 5 converts the input key command into an infrared remote control signal and transmits the signal. This step A
By executing step 2, the process shown in FIG. 4 is completed.

Next, the operation of the electronic device 6 will be explained based on FIG. 5.

FIG. 5 is a flowchart showing the operation of the electronic device 6. First, send key commands from remote control device 1 to electronic device 8.
The operation of registering in the RAM 12 will be explained. In this case, the mode selector switch 10b is set to "registration mode", and the function key 10a for setting the key command, for example, "
Operate the power ON key. Next, remote control device 1
From there, send a key command that you want to correspond to the "power ON key" of the electronic device θ. That is, "mode 1" of the remote control device 1 is made to correspond to the electronic device 6, and "key 1" is made to correspond to the electronic device 6.
If you want to make it correspond to the "power ON key", set the mode changeover switch 4b to "mode 1" and then operate "key 1". As a result, the remote control device 1 executes the process shown in FIG. Send from 5. The transmitted key command is immediately received by the receiving section 11 of the electronic device 6.

First, in step B1, it is determined whether there is reception or not, that is, whether the receiving section 11 has received the key command or remote control signal transmitted from the remote control device 1. This step B1
If it is determined to be YES, proceed to step B2 and select N.
If it is determined as o, the process advances to step B8. At this time, the remote control signal of the key command transmitted from the remote control device 1 is received by the receiving section 11, and the receiving section 11 converts the remote control signal of this key command into a digital data signal and outputs it to the control section 7, so YES. It is determined that step B
Proceed to step 2.

In step B2, it is determined whether the mode changeover switch 10b is set to "registration mode".

Since the mode changeover switch 10b is currently set to "registration mode," the determination is YES and the process proceeds to step B3. Further, if NO in step B2, the process advances to step B5.

In step B3, it is determined whether the function key 10a of the key operator 10 is being operated. This step B3
If it is determined to be YES, proceed to step B4.
If so, return to step B1. Since the "power ON key" of the function keys 10a is currently being operated, the answer is YES, and the process proceeds to step B4.

In step B4, the function key 10 being operated is
The key command received by the receiving section 11 is stored in one of the command storage sections R1 to R□, for example, the storage section R1, corresponding to the command storage section a. That is, the digital data signal of the received key command "command A" is stored in the command storage section R8 of the RAM 12 corresponding to the "power ON key" under the control of the control section 7. After executing step B4, the process returns to step B1.

Hereinafter, in the same manner as described above, with the function keys 10a of the electronic device 6 and the numeric keys 4a of the remote control device 1 corresponding to each other, the numeric keys 4a of the remote control device ff are operated, and the "key 2" corresponding to "mode 1" is pressed. - The key command of the remote control device 1 of "key 12" is registered in the command storage sections R1 to R9 of the RAM 12. As a result, key commands (command A, command B, . . . ) of "key 1" to "key 12" corresponding to "mode 1" are registered in the command storage units R4 to R1, respectively.

Next, the operation of transmitting a remote control signal of a key command from the remote control device 1 to control the electronic device 6 will be explained. In this case, the electronic device 6 is specified by setting the mode changeover switch 10b of the electronic device 6 to “search mode” and setting the mode changeover switch 4b of the remote control Hill to “so-1”. For example, suppose that "key 2" is operated on remote control device 1 in this state. As a result, the remote control device 1 executes the process shown in FIG.
The key command corresponding to "key 2", that is, "command B" is read from the ROM 3, converted into a remote control signal, and transmitted from the transmitter 5. The transmitted key command is immediately received by the receiving unit 11 of the electronic device 6.

Similarly to the above, in step B1, it is determined whether there is reception. Since the above-mentioned "command B" has now been received by the receiving section 11, the determination is YES and the process proceeds to step B2.

In step B2, it is determined whether the mode changeover switch 10b is set to "registration mode".

Since the mode changeover switch 10b is currently set to "search mode," the determination is NO and the process proceeds to step B5.

In step B5, the received key command is stored in the RAM 12.
It is determined whether the key command matches the key command stored in the command storage units R4 to R,l.

In the next step B6, it is determined whether or not the key commands match. If YES is determined in step B6, the process proceeds to step B7, but if NO is determined, the process returns to step B1 without executing anything. in this case,
Since the received "command B" is stored in the command storage section R2, YES is determined in step B6 and the process proceeds to step B7.

In step B7, the main body 9 is controlled according to the control codes stored in the control code storage units f1 to ffl corresponding to the command storage units R1 to Rfl that store key commands that match the received key command. in this case,
The main body section 9 is controlled according to the control code stored in the control code storage section f2 corresponding to the command storage section R2. Since the control code for the "channel 1 key" is currently stored in the control code storage section f2, the channel is switched to "1" in the main body section 9. This step B7
After execution, the process returns to step B1. In this way, the electronic device 6 receives the key commands transmitted from the remote control device 1 by RA.
Since the key commands are registered in M12 in advance, any type of remote control device 1 can control the electronic device 6 by registering the key commands.

Next, the operation of controlling the electronic device 6 by operating the function keys 10a of the key manual section 10 will be described. In this case, the mode changeover switch 10b of the electronic device 6 is set to "search mode". In this state, one of the function keys 10a is "Power ON".
Suppose that you operate the "N key".

At this time, there is no reception in step B1, so No.
It is determined that this is the case, and the process proceeds to step B8. In step B8, it is determined whether or not there is a key, and now the "power ON key" is pressed.
has been operated, the determination is YES and the process proceeds to step B9. If NO in step B8, the process returns to step B1. In step B9, it is determined whether the mode selector switch 10b is set to "search mode". now,
Since the mode selector switch 10b is set to "search mode", the determination is YES and the process proceeds to step BIO. Further, if NO in step B9, the process returns to step B1. In step BIO, the operated function key 10
The main body portion 9 is controlled according to a. That is, the main body section 9 is controlled according to the control code stored in the control code storage section f corresponding to the operated function key 10a (in this case, "power ON key"). In this case, the control code storage section f
Since the control code for the "power ON key" is stored in 1, the power to the main body section 9 is turned on.

After executing step B7, the process returns to step B1.

[Second Embodiment] FIG. 6 is a block diagram showing the circuit configuration of a control system for electronic equipment to which a second embodiment of the present invention is applied. The electronic device control system in this second embodiment includes, for example, three

Note that the configuration of the electronic device 6 in the second embodiment is completely the same as that shown in FIG. 1 above, so a description thereof will be omitted. Further, although FIG. 6 shows only the internal configuration of the electronic device 6 in detail, the internal configurations of the other electronic devices 13 and 14 are also substantially the same as the electronic device 6.

Next, the configuration of the wall clock 15 will be explained. As shown in FIG. 6, the main body case 15a of the wall clock 15 is provided with a time display section 16 on the front surface including a second hand 16a, a minute hand IBb, and an hour hand 18c. In addition, the main body case 15
In addition to the time display section 16, there is a light receiving element 17 on the front surface of the a.
A display section 18 and transmitting sections 19, 20, and 21 are provided. The light receiving element 17 is composed of, for example, a photodiode, a phototransistor, or the like. The display section 18 is composed of, for example, a liquid crystal display element. Transmission unit 19.
20.21 is equipped with a light emitting element that transmits a remote control signal using an infrared signal, and is configured so that the direction of transmitting the infrared signal can be freely set up, down, left, or right as shown in FIG.

FIG. 7 is a sectional view showing a support structure for the light emitting elements 22 provided in the transmitting parts 19, 20, and 21 of the main body case 15a in FIG. 6, respectively. The light emitting element 22 is composed of, for example, a light emitting diode and transmits an infrared signal. The light emitting element 22 has a transparent plastic 23 on the front and a fixing member 24.
It is supported by a hollow spherical support member 25 with a part cut out, and is movable vertically and horizontally, so that the transmission direction can be freely set according to the arrangement direction of the electronic device to be controlled. In addition, it is provided so as to protrude slightly from the front surface of the main body case 15a in order to widen the transmission range. Lead wire 2 connected to light emitting element 22
6 supplies the light emitting element 22 with an infrared drive signal output from a control section 28, which will be described later. The support member 25 is a support made of synthetic resin, for example, provided on the main body case 15a.
The receiver is supported by the member 7 so as to be movable vertically and horizontally, and the receiver is held at an arbitrary position by the frictional force of the member 27.

FIG. 8 is a block diagram showing the circuit configuration of the wall clock 15. In the figure, the control section 28 controls each section based on the microprogram stored in the ROM 29, and in addition to the ROM 29, the control section 28 controls the transmitting sections 19, 20, 21, and the RAM 3.
0, a key manual section 31, a frequency dividing timing circuit 33, a receiving section 34, a decoder driver 35, and a waveform shaping section 36 are connected.

The display unit 18 displays the current time based on display data supplied via the decoder driver 35. Note that the current time displayed on the display unit 18 and the current time displayed on the time display unit 16 are set in advance to match.

The transmitter 19, 20, 21 incorporates the light emitting element 22, and converts key commands for controlling external electronic devices 6, 13, 14 into remote control signals using infrared signals and transmits the signals.

RA, M 30 is a memory for storing various data, and the writing and reading of data is controlled by the control unit 28.

As shown in FIG. 9, this RAM 30 is composed of a register N that counts the number of key command transmissions, a clock register 30a that stores current time data, and a receive command register 30b that stores received key commands. .

The key manual unit 31 includes a time adjustment key (not shown) and the like. The oscillator 32 has a built-in crystal oscillator, for example, 32
A 768 Hz clock pulse is output and supplied to the frequency division timing circuit 33. The frequency division timing circuit 33 divides the frequency of the clock pulse input from the oscillator 32, generates various timing signals such as a clock signal, and supplies the generated timing signals to the control section 28. The clock signal is, for example, a 1 second signal, and the clock register 30
This is a signal for updating a and causing the clock mechanism 38 to move its hands.

The receiving section 34 includes the light receiving element 17 and the like, and receives a remote control signal in the form of an infrared signal transmitted from the remote control device 1, converts the received remote control signal into a digital data signal, and outputs the digital data signal to the control section 28.

The waveform shaping section 36 shapes the waveform of the hand movement signal output from the control section 28 every second and outputs the waveform to the step motor 37, thereby causing the step motor 37 to rotate.

The rotation of the step motor 37 moves the second hand 16a, minute hand 16b1, and hour hand IElc of the clock mechanism 88.

Next, the remote control signal of the key command transmitted from the remote control device 1 is relayed by the wall clock 15 to each electronic device IE.
The operation of sequentially transmitting data at t, 13 and 14 will be explained based on FIG. FIG. 10 is a flowchart showing the operation of the wall clock 15. In this case, the transmitter 19 shown in FIG.
．． 20.21 transmission direction for each electronic device E3.13.14
Set according to the direction in which it is placed. For example, the transmitter 18 may be placed in the direction of the electronic device 8, and the transmitter 20 may be placed in the direction of the electronic device 13.
The transmitter 21 is set so as to face the electronic device 14 in the direction shown in FIG. Also, the contents of register N in RAM30 are “
0”.

First, in step C1, it is determined whether the remote control signal of the key command transmitted from the remote control device 1 has been received by the receiving section 34. In this step C1, if it is determined that there is reception, the answer is YES and the process proceeds to step C2.
If there is no reception, N.

It is determined that the process proceeds to step C1j.

If no remote control signal is received, a negative determination is made in step C1, and the process proceeds to step C1l. In step C1l, whether or not it is time measurement timing, that is, the frequency division timing circuit 3
3, it is determined whether a clock signal (for example, a 1 second signal) has been output. If the determination is YES in step C11, the process proceeds to step C12, and if the determination is NO, the process returns to step C1.

Now, if the clock signal is output and the clock timing has come, the time update process in step C12 is executed, and the control unit 28 updates the current time data in the clock register 30a, and also sends a hand movement signal to the waveform shaping unit 36. Output. This hand movement signal is waveform-shaped by a waveform shaping section 36 and drives a step motor 37. As a result, the second hand 16a of the clock mechanism 38 advances by one second, and the time is updated.

After executing step C12, the process returns to step C1. Thereafter, the control unit 28 repeatedly executes steps C1, C11, and C12 until a remote control signal is received.

For example, when turning on the electronic device 6, the user points the remote control device 1 at the wall clock 15, sets the mode selector switch 4b to "mode 1", and then operates "key 1". As a result, the key command corresponding to "Mode 1" and "Key 1", that is, "Command A" is read from the ROM 3, converted into a remote control signal using an infrared signal, and transmitted. This remote control signal is received by the light receiving element 17 of the wall clock 15, and the receiving section 34 converts the remote control signal received by the light receiving element 17 into a digital data signal and outputs it to the control section 28. As a result, YES is determined in step C1, and the process advances to step C2.

In the data (command) storage process of step C2, the digital data signal of the key command inputted by the receiving section 34 is stored in the received command register 30b of the RAM 30 under the control of the control section 28.

In the next step C3, it is determined whether the key command reception process is completed. That is, it is determined whether the same key command has been received from the remote control device 1 twice in a row. If it is determined NO in step C3, return to step C1 and repeat steps 01 to C as described above.
3 is executed, and the digital data signal of the key command inputted from the receiving section 34 is stored in the received command register 30b of the RAM 30.

Then, when the same key command is received from the remote control device 1 twice in a row, the reception is completed, and in step C3
It is determined as ES and the process proceeds to step C4.

In step C4, it is determined whether the contents of register N are "0" or not. Since the contents of register N are now "0", the determination is YES and the process proceeds to step C5. Note that if the determination in step C4 is NO, the process advances to step C7.

In the A transmission process of step C5, the transmission process by the transmitter 19 is executed. That is, the key command (in this case, "command AJ") stored in the reception command register 30b of the RAM 30 is read out by the control unit 28, and
9 is output. The transmitter 19 converts this key command into a remote control signal using an infrared signal, and transmits the remote control signal using the light emitting element 22. In this case, since the light emitting element 22 is set toward the direction in which the electronic device 6 is arranged, the remote control signal based on the infrared signal is reliably transmitted toward the electronic device 6.

In step C6, the contents of register N are incremented by 1 to become "1", and the process returns to step C4.

In step C4, the contents of register N are changed to "
Since the contents of the register N are now "1", the result is NO and the process proceeds to step C7.

In step C7, it is determined whether the contents of register N are "1" or not. Now, the content of register N is "1", so Y
It is determined as ES and the process proceeds to step C8. Further, if the determination in step C7 is No, the process proceeds to step C9.

In the B transmission process of step C8, the transmission process by the transmitter 20 is executed. That is, the key command (in this case, "command AJ") stored in the reception command register 30b of the RAM 30 is read by the control section 28 and output to the transmitting section 20. The transmitting section 20 transmits this key command as an infrared signal. Converts to remote control signal by light emitting element 2
Send by 2. In this case, since the light emitting element 22 is set toward the direction in which the electronic device 13 is arranged, the remote control signal based on the infrared signal is reliably transmitted toward the electronic device 13. However, since the key command sent from the transmitter 20 is a key command compatible with the electronic device 8, the electronic device 13 will not operate, but if a key command compatible with the electronic device 13 is sent, the electronic device 13 will surely operate. do.

After executing step C8, the process returns to step C6.

In step C6, the contents of register N are +
1 and becomes "2", and the process returns to step C4. Similarly, in step C4, it is determined whether the contents of register N are "0" or not, and if the result is NO, the process proceeds to step C7. In this step C7, it is determined whether the contents of the register N are "1" or not, and since the contents of the register N are now "2", the result is No, and the process proceeds to step C9.

In step C8, it is determined whether the contents of register N are "2" or not. Since the content of register N is now "2", the answer is YES and the process proceeds to step CIO.

In the step CIO C transmission process, the transmitter 21 executes the transmission process. That is, the key command stored in the reception command register 30b of the RAM 30 (in this case,
Command Aj) is read by the control section 28 and output to the transmission section 21.

The transmitter 20 converts this key command into a remote control signal using an infrared signal, and transmits the remote control signal using the light emitting element 22. In this case, since the light emitting element 22 is set toward the direction in which the electronic device 14 is arranged, the remote control signal based on the infrared signal is reliably transmitted toward the electronic device 14. However, the key commands sent from the transmitter 21 are
Since the key command corresponds to the electronic device 14, the electronic device 14 will not operate, but if a key command corresponding to the electronic device 14 is sent, the electronic device 14 will definitely operate. Step CI
After executing O, the process returns to step C6.

In step C6, the contents of register N are +
1 and becomes "3", and the process returns to step C4. Similarly, in step C4, it is determined whether the contents of register N are "0" or not, and the result is NO, and the process proceeds to step C7. Since the contents of the register N are "3" in this step C7 as well, the determination is No and the process proceeds to step C9.

In step C9, as described above, it is determined whether the contents of register N are "2" or not, and since the contents of register N are now "3", it is determined that N=3, and step C13
Proceed to.

In step C13, "0" is written to the contents of register N and cleared. After executing step 013, the process returns to step C1.

Similarly to the above, the electronic devices 13 and 14 can also be controlled by relaying remote control signals of key commands transmitted from the remote control device 1 through the wall clock 15.

Note that in each of the above embodiments, key commands (control signals) are converted into infrared signals and transmitted from the remote control device, but the key commands are not limited to this and can be transmitted using radio wave signals, ultrasonic signals, magnetic signals, etc. You may.
