Detailed Description of the Invention

[0001]

Field of the Invention The present invention relates to a remote control device having a learning function of receiving and storing a control signal, and more particularly to a remote control device for efficiently storing a control signal in a memory and effectively utilizing the memory. Regarding control device.

[0002]

2. Description of the Related Art In recent years, devices such as tape recorders, audio equipment such as CDs, and video equipments such as televisions, videos and video disks have been increasing. These devices are usually
A remote control device (hereinafter referred to as a remote control) is attached, and the user can operate the device from a remote place by using the remote control.

As described above, the remote controller improves the convenience of the device. However, if the number of the devices to which the remote controller is attached increases, the number of remote controllers increases with the increase of these devices. Since a number of remote controls have to be operated side by side, the inconvenience of operating the remote controls is complicated and the location of the remote controls is also inconvenient.

Therefore, in order to solve these inconveniences, a remote controller (general-purpose remote controller) having a learning function is provided. The learning function is a function of receiving and storing a control signal for operating the device. Therefore, the user operates a plurality of devices with only one remote controller by storing a control signal of a required function such as turning on / off the power of the owned device to the remote controller having the learning function. Therefore, the above-mentioned inconvenience can be eliminated.

The control signal is usually output as a coded signal, and each maker uses a different code to prevent malfunction. Light emitting diodes are generally used to output control signals, and most manufacturers aim to save power by shortening the light emitting time of the light emitting diode, and to expand the light emitting ability of the light emitting diode by instantaneous light emission.

In order to store control signals having different lengths, formats, etc., a large-capacity memory must be installed in the device in advance, which raises the problem of increasing the cost of the device.

Further, in order to accurately reproduce the control signal received by the learning function, the content of the received control signal must be finely stored in the memory, so that the amount of data to be stored in the memory increases and the control signal Processing when sending and receiving becomes complicated,
There was a problem that the burden on work such as program development was heavy.

When the remote control devices are different even if the control signals are the same, the control signals actually output from the remote control devices do not completely match, and the burst pulse period (the reciprocal of which is the carrier frequency) and carrier Since some deviations occur in the output time, etc., each manufacturer assumes such a situation and designs the device with a certain allowable range. In general, the type (category) of signal units that make up a control signal often represents a digital value of "0" or "1". Therefore, the number of types of signal units is different even if the signal length is different. Often does not change.

The present invention has been made in view of the above problems, in which control signals are efficiently stored in a memory,
Further, it is an object of the present invention to reduce the memory cost and the device cost by reducing the memory capacity required to store a new control signal.

In the control signal shown in FIG. 3, a burst pulse composed of a carrier frequency continues for 1 ms, and then a signal called a leader pulse that continues for a low level period, which is also a rest period for 1 ms, is added to the beginning, and the end of the signal. Is configured by adding an end pulse.

A control signal for remotely controlling equipment such as a television and a video is generally composed of a combination of a digital signal of a bit showing a logical value "0" and a bit showing a logical value "1". Specifically, in the example shown in FIG. 3, one signal unit indicating “0” or “1” is defined by a carrier output time in which burst pulses are continuously output and a pause time in which a low level state continues. The type (category) of the signal unit is made different depending on the length of the pause time. That is, when the category of the signal unit is “1”, the pause time is 1 ms, and the category of the signal unit is “1”.
In the case of "0", the pause time is 0.5 ms, and the carrier output time is 0.5 ms. The burst pulse period, which is the time from when the burst pulse rises until when it rises again, is the same period (this The reciprocal is the carrier frequency).

Upon receiving these measurement results from the reception control unit 105, the control unit 101 calculates the carrier frequency, determines the type of the control signal and the category of the signal unit that constitutes the control signal, and determines the control signal of the determined type. , The signal unit category is R
It is determined whether or not the measurement result data is already stored in the OM 115 or the RAM 116, and the RAM 116 stores (learns) only the required measurement result data. In addition, the control unit 101
Reads the control signal data stored in the ROM 115 and the RAM 116 and controls the transmission control unit 107 based on the read data to restore the learned remote control signal. As a result, the LED 106 is driven by the transmission control unit 107, and the reproduced control signal is transmitted.

FIG. 4 is a block diagram showing the configuration of the reception control section 105. The reception control section 105 includes S / R flip-flops 401, 402 and 403, AND gates 404, 405 and 406, and a counter. 407, 40
8 and 409, ternary counters 410 and 411,
It comprises a one-shot circuit 412 and an inverter 413.

That is, the output of the photodiode 104 in FIG. 1, that is, the received pulse of the received control signal is S
/ R flip-flops 401 and 403 S (set)
Terminal, ternary counter 410, and one-shot circuit 41
2 are input respectively. The one-shot circuit 412 is a circuit that is triggered each time a pulse signal is input and maintains an output of "1" for a predetermined period, and its output is the inverter 41.
3 and the AND gate 405. Therefore, when the burst pulse of the control signal is input, the output of the one-shot circuit 412 also becomes "1" and holds "1" while the burst pulse is continuously input, and as a result, the inverter 413 outputs The output of “0” is input to the R (reset) terminals of the S / R flip-flops 401, 402 and 403.

When a burst pulse is input, S
The / R flip-flop 401 is set and its Q terminal output becomes "1". The ternary counter 410 is a counter that counts the burst pulse three times and outputs a carry signal that becomes "1" at the fourth time. The ternary counter 411 counts the carry signal twice and the carry signal at the third time. Output a signal. Bar Q of the S / R flip-flop 402
The output of the terminal is "1" until the carry signal is output from the ternary counter 410. The AND gate 404 is S
/ R flip-flop 401 Q terminal output, S / R flip-flop 402 bar Q terminal output, and control unit 10
Since the clock having the predetermined frequency from 1 is input and the logical product of the clocks is output to the counter 407, the counter 407 outputs 3
The time until the carry signal is output from the advance counter 410 is counted. That is, the counter 407 measures the time for three cycles of the burst pulse. The time data counted by the counter 407 is sent to the control unit 101.

On the other hand, the counter 408 has the AND gate 4
The clock output from 05 is counted. The AND gate 405 outputs the output of the one-shot circuit 412 and S / R.
The logical product of the Q terminal output of the flip-flop 403 and the clock is output. The output of the inverter 413 is "0" while the output of the one-shot circuit 412 is "1",
During this period, the Q terminal output of the S / R flip-flop 403 is "1". Therefore, the output of the AND gate 405 outputs the clock while the burst pulse is continuously input and the output of the one-shot circuit 412 is "1". Therefore, the counter 408 measures the carrier output time by counting the clock. Burst pulse stops, one-shot circuit 41
When the output of 2 becomes "0", the counter 408 finishes counting and the S / R flip-flop 403 is reset. When the burst pulse is input again, the counter 4
08 starts counting again from the reset state. The carrier output time data of the counter 408 is sent to the control unit 101.

The counter 409 counts the clock output from the AND gate 406. AND gate 4
06 outputs the logical product of the output from the Q terminal of the S / R flip-flop 403 and the clock. The output from the bar Q terminal of the S / R flip-flop 403 is the one-shot circuit 41
The output of 2 is "1" while it is "0", that is, during the rest time when there is no burst pulse. Therefore, the counter 409 is
The pause time is measured by counting the clocks output from the AND gate 406.

As described above, the ternary counter 410 counts the burst pulse, and the time data during that time is measured by the counter 407. When the carry signal is output from the ternary counter 410, the carry signal is counted by the ternary counter 411 and the S / R flip-flop 402 is set to set the bar Q terminal to "1".
The signal at the bar Q terminal of the S / R flip-flop 402 is also sent to the ternary counter 410, and the ternary counter 410
When the "1" signal is sent from the bar Q terminal, the counting operation is stopped although the details are not shown. Therefore, the counting operation is not performed after the fourth burst pulse among the continuous burst pulses.

Further, the output of the inverter 413 is 3 above.
It is also sent to the advance counter 410. Ternary counter 41
When the "1" signal is input from the inverter 413, "0" cancels the stopped state of the count operation, although not shown in detail. As a result, the ternary counter 410 performs the counting operation from the reset state when the burst pulse is applied next after the rest period.

The ternary counter 411 is a ternary counter 41.
The carry signal of 0 is counted, and the carry signal is output to the control unit 101 at the third counting. The control unit 101 measures (calculates) the carrier frequency, as described later, using the time data of the counter 407 until the carry signal comes from the ternary counter 411.

FIG. 5 is an explanatory diagram showing an example in which the control signal shown in FIG. 3 is received, and the operation of the reception control section 105 described above will be concretely described taking the case where the control signal shown in FIG. 3 is received as an example. Explained. When the ternary counter 410 outputs the carry signal for the first time after receiving the first leader pulse, the counter 407 counts the time T1 for three cycles of the burst pulse. On the other hand, in the counter 408, the output of the one-shot circuit 412 is “1”.
The carrier output time X1 which is the time is counted. The counter 409 counts the pause time Y1 while the output of the burst pulse ends and the output of the one-shot circuit 412 is “0”.

When the burst pulse is input again after the pause time Y1 has elapsed, the counter 407 changes the ternary counter 4
Counting from the previous time is continued until 10 outputs the carry signal for the second time. Therefore, when the ternary counter 410 outputs the carry signal for the second time, the counter 407:
This means that the time T1 + T2 is being counted. In this way, counting is performed until the ternary counter 411 outputs the carry signal three times.
7 is a burst pulse 9 which is the time of T1 + T2 + T3
The time for the cycle is counted, and this value is sent to the control unit 101.

On the other hand, the counter 408 counts the carrier output times X2 and X3, and the counter 409 counts.
The pause times Y2 and Y3 are counted. The time of one cycle of the burst pulse is determined by multiplying the count value of nine cycles of the burst pulse (T1 + T2 + T3) counted by the counter 407 by the clock cycle and then dividing by 9 to obtain the reciprocal of the determined cycle. Find the carrier frequency. In this way, by measuring the periods of a plurality of burst pulses in order to determine the time for one period of the burst pulse, it is possible to reduce the influence of malfunctions and the like, and to accurately grasp the carrier frequency of the control signal. You can

Similarly, the carrier output time and the rest time are calculated by multiplying the count values counted by the counters 408 and 409 by the clock cycle, respectively.
A category for each signal is determined from the calculated value, and the determined category is temporarily stored in the work area of the RAM 116 as described later.

FIG. 6 is a flowchart showing the series of processing operations described above, and the processing operations described above are as follows. First, the control signal is received by the photodiode 104 (S11), the burst pulse period is measured by the counter 407, and the carrier frequency is calculated from the count value of the counter 407 (S12). The carrier output time and the pause time are measured by the counters 408 and 409, respectively, and the carrier output time and the pause time are calculated from the count values of the counters 408 and 409, respectively (S13). When each time length is calculated, the category of the signal unit is determined from the calculated each time length, and the RAM 1
It is once stored in the work area of 16 (S14). This processing operation is continuously executed until the reception of the control signal is completed.

When the reception of the control signal is completed, the categories of signal units of the received control signal are sequentially read from the work area of the RAM 116 by the processing described later, and the type of control signal is selected from the order in which the category of signal units is stored in the RAM 116. Is determined and compared with the content already stored in the ROM 115 and the RAM 116 together with the already determined signal unit, and only the necessary data is stored in the RAM 116.

Next, the transmission control section 107 will be described. FIG. 7 is a block diagram showing the configuration of the transmission control unit 107. As shown in the figure, the transmission control unit 107 includes time length setting units 701, 702, and 703 for setting the respective time lengths of control signals to be transmitted. Time length setting unit 703
Register 704 that is shifted by the time length setting unit 7
S / R flip-flop 705 set by 01
And the output of the register 704 and the S / R flip-flop 7
05 outputs the logical product of the bar Q terminal output,
And an AND gate 706 which supplies an output signal to

The time length output circuit 70 of the time length setting unit 701
7, the control unit 101 sets the time length of the high level time of the burst pulse, and outputs the data representing the set time length to the coincidence detection circuit 708. Match detection circuit 7
08 is "1" when the data output by the time length output circuit 707 and the value counted by the counter 709 match.
Signal A ₀ of S / R flip-flops 705 and 710
To the time length setting unit 702. The counter 709 counts the output clock of the AND gate 711. Since the AND gate 711 outputs the logical product of the clock and the output from the Q terminal of the S / R flip-flop 710, the counter 709 counts the clock until the match detection circuit 708 detects a match.

When the coincidence detection circuit 708 detects a coincidence, "
When the signal A _{0 of} 1 "is output, the S / R flip-flops 705 and 710 are both set, and the output of the bar Q terminal becomes" 0 ". The coincidence detection circuit 708 outputs the signal A of" 1 ".
Until ₀ is output, the output of the S / R flip-flop 705 at the bar Q terminal is "1". At this time, if "1" is output from the register 704 as described later, the output of the AND gate 706 is "1". ", And the LED 106 is driven. Therefore, at this time, the burst pulse of the high level time set in the time length output circuit 707 is output.

The time length setting unit 702 is a time length setting unit 70.
The control unit 101 sets the time length of the low level time of the burst pulse in the time length output circuit 712. When the coincidence detection circuit 708 outputs the signal A ₀ of “1”, the S / R flip-flop (corresponding to the S / R flip-flop 710 of the time length setting unit 701.
The number of the time length setting unit 701 is shown in parentheses) and the bar Q terminal output becomes "1", and the counter (709) counts. The time length output circuit 712 outputs data representing the time length of the low level time of the burst pulse set by the control unit 101 to the coincidence detection circuit (708), and the count value of the counter (709) corresponds to this data. When they match, the signal of "1" A ₁
S / R flip-flop 705 and time length setting unit 70
1 to the R terminal of the S / R flip-flop 710. Also, it sets its own S / R flip-flop (710). As a result, the S / R flip-flop 7
05, and the S / R flip-flop 710 of the time length setting unit 701 is reset and the output of the bar Q terminal is "1".
Then, the counter 709 of the time length setting unit 701 restarts counting. Therefore, during this period, the AND gate 706
Keeps low level.

The time length setting unit 703 sequentially sets the carrier output time and the rest time, and outputs the signal B when the set time has elapsed (such a timer circuit is well known. Is not shown). In the time length output circuit 713 of the time length setting unit 703, the control unit 101 sequentially sets the time length according to the carrier output time and the rest time. First, when the carrier output time is set, a counter (not shown) counts a clock, and when the count value of the counter and the carrier output time of the time length output circuit 713 match in the coincidence detection circuit "
1 "signal B is output. And the time length output circuit 71
A pause time is set in 3, and the counter starts counting from the beginning. Signal B of "1" from the time length setting unit 703
Is output, the contents of the register 704 are shifted to the right toward FIG.

As shown in FIG. 7, the register 704 has "
1 "and" 0 "are alternately stored, and the rightmost value is the output to the AND gate 706. Therefore, by changing the time length set in the time length output circuit 713,
The carrier output time and the rest time can be easily switched. 9 and 10 are explanatory diagrams (ROM maps) showing an example of the contents of the ROM 115. FIG. 9 shows the area in which the data table is stored, and FIG. 10 shows the area in which the category table is stored.
(However, num indicates a number, and the same applies when described below), and Cnum indicates an address of each table.

The category table is a table in which time length data (hereinafter, referred to as category data) representing a signal unit (usually 1 bit) forming a control signal is classified into categories and stored. In the above, as the category data, the carrier output time and the total output time which is the total time during which the signal of the category is output are stored. Specifically, for example, at address C0, 1.00 ms is the carrier output time,
2.00 ms indicates the total output time, that is, the time obtained by adding the carrier output time and the rest time. Therefore, in the signal unit category stored in the address C0, 1.0
0 ms is the rest time. The same applies to the contents stored in other addresses.

The data table is a table in which control signals are classified and stored for each function (type).
Data necessary for reproducing a control signal, excluding category data, is stored in one address indicated by Tnum. Specifically, for example, in the address T0, general data of the control signal is stored in the address indicated by Anum, and an address group designating the address of the category table is stored in the address indicated by Enum in the order of transmission in signal units.

As general data at the address T0,
16 is stored in the address A0 as the total number of data stored in the address T0, and 40 is stored in the address A1.
Is stored as a carrier frequency (KHz), 2 is stored in the address A2 as the number of repeats of the control signal, and PE1 is stored in the address A3 as a repeat start address. On the other hand, as an address group for designating the address of the category table, the address E0 is PC0, the address E1 is PC1, the address E2 is PC2, and the address E is PC2.
3 is stored in PC1, and address E4 is stored in PC1.

The PE1 stored as the repeat start address in the address A3 has the address E1 in the address T0.
Is shown. The P at the head of E1 is added to indicate that this data designates an address, and similarly, the data designating an address will also have P added to the head thereof. Therefore, the data stored at the address E0 is the address C0 of the category table.
Is specified, and the other addresses similarly specify the category table address. Further, since the data group consisting of the general data and the address group stored at one address indicated by Tnum represents the category of the signal unit forming the control signal, the order of the signal unit, etc., this data group is used as a pattern. Will be described.

As described above, by storing only the category data as one table collectively, it is not necessary to store the same category data, so that the memory capacity required for storing the control signal can be reduced. Since the number of categories of signal units constituting the control signal is smaller than the number of functions of the control signal, this method is effective in reducing the memory capacity required for storing the control signal.

The address Tnum of the data table
As will be described in detail later, is specified by the F1 to 3 keys in the transmission mode, and the control signal learned in correspondence with the number of the ten key 201 in the learning mode is stored in the data table of the ROM 115. If so, the address of the corresponding data table is stored in the RAM 116.

FIG. 11 is an explanatory diagram (RAM map) showing an example of contents stored in the RAM 116. As shown in FIG. 11, the RAM 116 includes a display register 21 that stores data for displaying on the display device 102, a timekeeping register 22 that stores the current time, a stopwatch register 23, and an alarm time register 24. , Each flag indicating the currently set mode (M, B,
There are various register areas such as the register area 25 in which C) is stored. Further, similar to the ROM 115, there are a data table and a category table area, and further, there is a work area area in which the categories of signal units forming the received control signal are sequentially stored when the control signal is learned.

In this embodiment, the control signal is stored in correspondence with each key of the numeric keypad 201. Knum
Is the address assigned to each key, for example
The 0 key of the numeric keypad 201 is assigned to the address K0, the 1 key is assigned to the address K1, and the 2 key is assigned to the address K2. The same applies to other addresses.

Data indicating the address of the data table is stored at the address indicated by Knum, and category data is stored at the address indicated by Nnum. For example, PL0 stored at address K0 is
6 shows the address L0 of the data table in FIG. The types of data stored in the data table of the RAM 116 are the same as those of the ROM 115. For example, since 11 is stored as the total number of data in the address L0, it is necessary that the pattern, which is the data group representing the control signal learned in association with the 0 key, is stored in the addresses L0 to L10. It represents. That is, PL0 stored at the address K0 is the leading address where the pattern of the control signal corresponding to the 0 key is stored.

The control signal corresponding to the 0 key has a carrier frequency of 40K from the data of the address L1.
Since the number of repeats is 0 and the number of repeats is 0 from the data of Hz and the address L2, no data is stored in the address L3, and the category stored in the address N0 from the PN0 stored in the address L4 is used as the control signal. You can see that it is sent first.

On the other hand, PL11 is stored in the address K1 and 10 is stored in the address L11. Therefore, the pattern of the control signal corresponding to one key is
It can be seen that it is stored in the addresses L11 to L20. Further, since PT0 is stored in the address K2, it can be seen that the control signal of the address T0 in the data table of the ROM 115 shown in FIG. Therefore, when the control signal of the 2 key is selected as the control signal to be transmitted, since PT0 is stored in the address K2, the pattern is read from the address T0 of the ROM 115, and further the category data is read.
The control signal will be reproduced.

Further, in FIG. 11, all the data indicating the address of the category table stored in the pattern of the control signal is the address in the RAM 116, but depending on the control signal to be stored,
All of this data may indicate an address in the ROM 115. Therefore, in this case, since the category data is not stored, the memory capacity required for storing the control signal can be effectively reduced.

The address Knum is designated by the numeric keypad 201 in the transmission mode and learning mode, which will be described later, and the numeric keypad 2 is used in the transmission mode.
The control signal stored at the address Knum designated by 01 is transmitted, and in the learning mode, at the address Knum designated by the ten key 201,
Data that specifies the address where the learned control signal pattern is stored is stored.

Next, processing operations of various controls executed by the control unit 101 in this embodiment will be described. FIG. 12 is a flowchart showing a main routine process for executing the overall control in this embodiment, and the overall control will be described first.

The control unit 101 is in a halt state (HALT) when no processing is performed (step S101), and when a clock that is a clock signal is input from the frequency dividing / timing circuit 113, the clock processing that counts the input clock. Is executed (S102), and when a key operation is performed, a key process corresponding to the operated key is executed (S103).
When the time counting process or the key process is completed, it is then determined whether the value of the flag M indicating the currently set mode is 0 (S104).

The modes of the remote control device according to this embodiment will be described below. Figure 13
FIG. 7 is an explanatory diagram showing display examples in various modes in the present embodiment.

As shown in FIG. 13, the flag M is used in this embodiment.
There are three types of values of 0, 1, 2; clock mode when the value of the flag M is 0, remote control mode when the value of the flag M is 1, and learning check when the value of the flag M is 2. Mode. Switching between these modes is performed by operating the S1 key. Specifically, the flag M
When the S1 key is operated once when the value of is 0, the value of the flag M is switched to 1, and when the S1 key is operated once again, the value of the flag M is switched from 1 to 2. Flag M
When the value of is 2 and the S1 key is operated once, the value of the flag M becomes 0 again. In this way, each time the S1 key is operated, the value of the flag M is sequentially switched from 0 to 1, 1 to 2, 2 to 0.

Within each mode indicated by the flag M, there are a plurality of modes indicated by the flag B, respectively. For example, flag M
In addition to the basic clock mode in which the value of the flag B is 0, the clock mode in which the value of 0 is 0, the calculation mode in which the value of the flag B is 1 (CAL), and the alarm in which the value of the flag B is 2 (ALM ) Mode, there is a stopwatch (STW) mode in which the value of the flag B is 3, and these modes are sequentially switched each time the S3 key is operated. The remote control mode in which the value of the flag M is 1 includes the transmission mode in which the value of the flag B is 0 and the learning mode in which the value of the flag B is 1, and the mode is switched each time the S3 key is operated. .

Returning to FIG. 12, the description of the subsequent processing will be continued. If it is determined in step S104 that the value of the flag M is 0, data corresponding to the value of the flag B is displayed (S105), the process returns to step S101, and the subsequent processes are continued. If it is determined that it is not 0, then it is determined whether the value of the flag M is 1 (S10).
6). If the value of the flag M is judged to be 1, then it is judged whether or not the value of the flag B is 0 (S107). If the value of the flag B is judged to be 0, the device name, function, etc. operated by the control signal to be transmitted. Is displayed (S108), and step S
Returning to the processing of 101, if it is determined that the value of the flag B is not 0, the result of learning the control signal is displayed (S109), and the processing returns to step S101. If it is determined in step S106 that the value of the flag M is not 1, the content of the learned control signal is displayed (S110), and the process returns to step S101.

FIGS. 14 (a) to 14 (c) are illustrations showing a display example in the remote control mode in this embodiment, and FIG. 14 (d) is an illustration showing a display example of the learning result in the learning check mode. In FIG. 14A, the number “8” is blinking and “Er” is displayed in the upper right. This means that the control signal was stored (learned) in association with the 8 keys, but an error occurred and the control signal could not be stored. Also, FIG. 14 (b) shows a case where the number of signal units of the control signal received is large and overflow occurs. In FIG. 14 (c), the number “8” disappears and the number corresponds to the 8 key. This indicates that the control signal is normally stored.

FIG. 14D shows a case where the contents of the control signal stored at this time are displayed in the learning check mode (the value of the flag M is 2). In FIG. 14D, “03” on the left side is the number of categories of the control signal in the signal unit, “40” that follows is the carrier frequency (KHz), and “0.50” is the carrier output time (ms).
Are shown respectively. As described above, in this embodiment, the user can understand the content of the learned control signal.

FIG. 15 is an explanatory diagram showing a display example of the learning result in another embodiment. In the figure, "F5"
Indicates that the number of categories is 5, "34" indicates the carrier frequency, and "0464" indicates the carrier output time. For example, the unit of burst pulse period is 0.5 μs, and the unit of carrier output time is 8 μs.
Then, the carrier frequency is 1 ÷ (34 × 0.5) = 3
8.46 KHz, carrier output time is 0464 × 8 =
Each represents 3.712 ms. Therefore,
By using this display method, the carrier frequency and the carrier output time can be more accurately grasped as compared with the display of the learning result according to the present embodiment.

Next, the key processing will be described. The key processing is to execute processing according to the type of the operated key. FIG. 16 is a flowchart showing the key processing, and its operation will be described with reference to the figure.

First, it is determined whether the value of the flag M is 0 (S201). If it is determined that the value of the flag M is 0, that is, if it is determined that the clock mode is set, then it is determined whether or not the S1 key has been operated (S202). If it is determined that the S1 key has been operated, the flag M is set to 1 Set (S20
3), a series of processing is ended. On the contrary, if it is determined that the operated key is not the S1 key, it is then determined whether or not the S3 key is operated (S204), and if it is determined that the S3 key is operated, the value of the flag B is incremented (however, the flag B is incremented). If the value of B is 3, set 0)
That is, that is, the mode is switched in the clock mode (S205), and the series of processes is ended. Conversely, if it is determined that the operated key is not the S3 key, key processing according to the currently set mode is executed (S20
6) Then, a series of processing is ended.

If it is determined in step S201 that the value of the flag M is not 0, then it is determined whether the value of the flag M is 1 (S207). If it is determined that the value of the flag M is 1, that is, if the remote control mode is determined, it is determined whether the S1 key is operated next (S208). If it is determined that the S1 key is operated, the flag M is set to 2 ( S20
9) Then, a series of processing is ended. If it is determined in step S208 that the operated key is not the S1 key, it is then determined whether the S3 key has been operated (S21
0), if it is determined that the S3 key has been operated, the value of the flag B is incremented (S211), and a series of processing is ended. Here, the increment of the value of the flag B in step S211 is to switch between 0 and 1 because the value of the flag B in the remote control mode is 0 or 1, so that the transmission mode and the learning mode are switched (see FIG. 13) is performed.

If it is determined in step S210 that the operated key is not the S3 key, then the ten key 20
It is determined whether 1 has been operated (S212). When it is determined that the numeric keypad 201 has been operated, it is next determined whether or not the value of the flag B is 0 (S213), and it is determined that the value of the flag B is 0. Then, the control signal of the data table designated by the data stored in the address (Knum) of the RAM 116 is transmitted (S214), the series of processes is terminated, and conversely, it is determined that the value of the flag B is not 0, That is, when it is determined to be the learning mode, the corresponding key displayed on the display device 102 is displayed in a blinking manner (S215), and a series of processing is ended. In this embodiment, as shown in FIG. 13, the number of the designated key is displayed or blinked in the remote control mode, so that the user can confirm the operated key number.

When it is determined in step S212 that the operated key is not the ten-key 201, it is next determined whether the F1 key or the F2 key is operated (S21).
6). Here, in the present embodiment, when the value of the flag M is 1, the F1 key and the F2 key are the manufacturer designation key, F
The 3 key serves as a key for designating functions such as power on / off and channel selection, and the F4 key serves as a key for starting transmission of control signals.

If it is determined in step S216 that the F1 or F2 key has been operated, it is next determined whether the value of flag B is 0 (S217). If the value of flag B is determined to be 0, according to the operated key. A maker (company) is selected (S218), and a series of processing ends. The keys operated in step S216 are the F1 key and the F2 key.
If it is determined that it is not the key, and step S217
When it is determined that the value of the flag B is not 0 in
Next, it is determined whether the F3 key has been operated (S21).
9).

When it is determined that the F3 key has been operated, it is next determined whether or not the value of the flag B is 0 (S220), and when it is determined that the value of the flag B is not 0, a series of processing is terminated here, On the contrary, if the value of the flag B is judged to be 0, the function of the control signal is selected according to the operation of the F3 key (S2
21), and a series of processing ends.

If it is determined in step S219 that the operated key is not the F3 key, it is then determined whether the F4 key has been operated (S222). If it is determined that the operated key is not the F4 key, here. If it is determined that the F4 key has been operated after the series of processing is completed, then it is determined whether the value of the flag B is 0 (S223). When the value of the flag B is judged to be 0, the control signal selected by the F1 to 3 keys or the numeric keypad 201 is transmitted (S224), the series of processing is ended, and conversely, it is judged that the value of the flag B is not 0. Then, the learning process of receiving and storing the control signal is executed (S225), and the series of processes is ended.

If it is determined in step S207 that the value of the flag M is not 1, it is then determined whether the F3 key has been operated (S226). If it is determined that the operated key is not the F3 key, the series of processing ends here,
On the contrary, when it is determined that the F3 key is operated, the display device 1
The address of the display register 21 (see FIG. 11) of the RAM 116 in which the data to be displayed on 02 is stored is updated according to the key operation (S227), and the series of processes is ended.

As described above, by executing the key processing according to various key operations, the mode is switched from the clock mode to the remote control mode and the control signals are transmitted and received. In addition, the display register 21 is operated according to the key operation.
The display device 1 is updated by updating the address in
In 02, the type of control signal to be transmitted (currently selected) is displayed. This allows the user to select the control signal while viewing the content displayed on the display device 102.

Next, the receiving process will be described. The reception processing receives the control signal, and the received control signal is RA in the form of a data table or category table.
This is a process to be stored in M116, and is executed in the process of step S225 in the key process shown in FIG. Figure 1
7 is a flowchart showing the receiving process, and its processing operation will be described with reference to FIG.

First, the time data counted by various counters (see FIG. 4) is stored (S401), and it is determined whether or not there is an error (S402). If you determine that there were no errors, then determine whether there was an overflow,
If it is determined that there is no overflow, the carrier frequency, the carrier output time, and the pause time are calculated from the stored time data and stored (S404), the category for each signal unit is determined from the calculated time, and the determined signal unit is determined. Determine the type of control signal from the category (S
405). Here, the error is, for example, a case where the carrier output time or the pause time is longer than a preset time, a case where there is a malfunction, and the overflow is a case where the number of signal units is more than a predetermined number. .

When the process of step S405 ends, the same pattern as the control signal determined next is stored in the ROM.
115, or it is judged whether or not it is already stored in the data table of the RAM 116 (S406). When it is determined that the same pattern is already stored in the data table, the RAM 116 specified by the ten-key 201 is used as the address of the data table in which the pattern is stored.
The address is stored in the address Knum (S407), and the series of processing is terminated.

If it is determined in step S406 that the same pattern is not stored in the data table,
ROM 115 or R in each signal unit judged
The category data for each signal (carrier output time and total output time) not stored in the category table of AM116 is stored in the category table of RAM116, and the pattern representing the received control signal is RA.
The address of the pattern stored in the data table of M116 is stored in the address Knum designated by the operated ten-key 201 (S408), and the series of processes is ended.

If it is determined in step S402 that there is an error, and if it is determined in step S403 that there is an overflow, the processing corresponding to each case is executed (S409), and the series of processing is terminated. .

As described above, in this embodiment, the learned control signal is divided into the data table and the category table and stored in the RAM 116. As a result, compared with the case where the control signal is simply stored, at least the memory capacity required for storing the category data can be reduced, and the cost of the memory can be suppressed, so that the cost of the device can be reduced. In ROM115,
Since the category table is stored in advance, the category data newly stored by learning the control signal is practically small.
It is possible to further reduce the storage capacity required for the above. This means that in view of the number of control signals that can be stored, many control signals can be stored even with a small storage capacity, and since category data is stored as a table, some control signals can be stored. This means that the amount of data can be greatly reduced.

Further, in the present embodiment, in step S405 of the reception processing, the category is determined in consideration of some malfunction of other remote control device which has transmitted the control signal for storing the control signal, the characteristics of the device, and the like. is doing. As a result, when the actually received signal unit is somewhat similar to the already stored category, it is determined to be the same category, so that the required memory capacity can be further reduced.

Next, the transmission process will be described. The transmission process is a process of reading the pattern of the data table stored in the ROM 115 and the RAM 116, reading the category data from the read pattern, and reproducing the control signal to transmit the control signal. The key shown in FIG. In the process, step S2
14 and one of the processes in S224. FIG. 18 is a flowchart showing the transmission process,
The processing operation will be described with reference to FIG.

First, the F1 to 3 keys or the numeric keypad 20
The pattern of the data table of the control signal designated by 1 is stored in the ROM 115 or the RAM 116 (see FIG. 9).
11), the high level time and the low level time of the burst pulse are calculated from the carrier frequency of the read pattern with a duty of 1/5 and stored (S301). At this time, when 40 KHz is read as the carrier frequency, the high level time of the burst pulse becomes 5 μs and the low level time is 20 μs.
s.

When the processing of step S301 is completed, the category data stored at the address of the category table designated by the address group of the read pattern is read to calculate the carrier output time and the rest time, and the calculated time is calculated. The length is temporarily stored as data in the work area of the RAM 116 (S302). RAM116
The data stored in is transmitted to the transmission control unit 107, and the transmission control unit 107 drives the LED 106 in accordance with the transmitted data, whereby the control signal is restored and transmission is executed (S303), and a series of processing ends. To do.

FIG. 8 shows the data thus stored in the work area of the RAM 116. From the left in FIG. 8, 5 μs is the pulse width (high level time) of the burst pulse, 20 μs is the low level time of the burst pulse, 1 ms is the carrier output time of the leader pulse, 1
ms is the pause time of the leader pulse, the next 0.5 ms is the carrier output time of the logical value "0", and 0.5 ms is the logical value "
0 "is a pause time, 0.5 ms is a carrier output time of a logical value" 1 ", and 1 ms is a pause time of a logical value" 1 ". Therefore, when transmitting the control signal shown in FIG. A time length of 5 μs is set for the time length output circuit 707 of the control unit 107, and the time length output circuit 712 is set.
Is set to 20 μs, and the time length output circuit 713
1ms, 1ms, 0.5ms, 0.5ms, 0.5
The time length may be sequentially set in the order of ms and 1 ms.

By the way, in this embodiment, the duty, which is the ratio of the period in which the burst pulse is at the high level in one cycle, is set to ⅕. Therefore, as described above, the time length output circuit 707 is set to 5 μs and the time length output circuit 712 is set to 20 μs.
The carrier frequency of this control signal is 40 KHz
(1 cycle is 25 μs).
Here, the duty is set to ⅕ in most of the control signals whose duty is ⅓,
This is because even if the duty is set to 1/5, there is no practical problem in the operation of the device, and the power consumption can be suppressed.

As described above, since the reproduction of the control signal is performed with the preset duty, the amount of data required for the reproduction of the control signal can be reduced, so that the required memory capacity can be reduced and the device can be reduced. Can reduce the cost. Further, reducing the amount of data required to reproduce the control signal means that the process of transmission and reception is simplified. For this reason, it becomes easy to develop a program for executing processing in transmission and reception, and it is possible to reduce the load in these operations.

In this embodiment, the duty of the high level time of the burst pulse is ⅕ at the carrier frequency of the stored control signal, but the present invention is not limited to this. Also, most manufacturers
The carrier frequency is set to 38 or 40 KHz and the duty is set to 1/3.
There is no practical problem even if the KHz and the duty are preset to 1/5. Therefore, in this case, it is not necessary to measure the burst pulse period as in the present embodiment, so that the amount of data to be stored for reproducing the control signal can be further reduced and the transmission / reception processing can be further simplified. In addition to the effect, there is an effect that power consumption can be suppressed.

Also, since each manufacturer uses its own control signal, there are many kinds, and there are many kinds of signal units that compose the control signal. However, a light emitting diode is used to output the control signal. Therefore, most of the control signals are configured by combining burst pulses, and the signal unit indicates the type by the carrier output time, the number of pause times, each time length, the transmission order, and the like. Therefore, by measuring each time length of the carrier output time and the rest time, it is possible to recognize the category of the signal unit forming the control signal. Since the control signal is configured by such a configuration, the present invention can be widely applied.

[0096]

As described above, since the remote control device of the present invention reproduces the burst pulse of the preset duty based on the burst pulse cycle of the received control signal, it is necessary for the reproduction of the control signal. By reducing the amount of data to be transmitted, the processing at the time of transmission and reception is simplified, the program development etc. becomes easy and the burden on these tasks is reduced, and
The cost of the memory can be suppressed and the cost of the device can be reduced.

Further, since the carrier output time and the rest time of the received control signal are measured, it is possible to recognize the type of signal unit forming the control signal, and to reproduce and transmit the received control signal. You can

Further, the control signal is made to correspond to the area for storing the time length data of various signal units forming the control signal and the address storing the time length data of various signal units in correspondence with the signal unit forming the control signal. Is classified into an area to be stored as an address group and stored, so that the memory capacity required in advance or for storing a new control signal can be reduced, which can reduce the memory cost and the device cost. it can.

Further, by making the burst pulse cycle the average of a plurality of burst pulse cycles, it is possible to reduce the influence of malfunction and the like, and it is possible to accurately grasp the burst pulse cycle. Furthermore, by combining these things, it is possible to obtain higher effects described above.
