It is to be noted that before the explanation of carrying out the preferred embodiments of the present invention identical parts are represented by identical reference number.
With reference to Fig. 1, it represents an essential part of first preferred embodiment of the present invention, a studying method of memory remote control device according to first preferred embodiment of the present invention comprises a photodiode 1 that is used to receive remote signal, a shaping circuit 2 that wherein includes a single-shot trigger circuit, the remote signal that receives is delivered to shaping circuit 2 so that carry out shaping, thereby just as the remote control in the prior art, provide a pulse signal and an envelope signal.To deliver to microcomputer 3 from the pulse and the envelope signal of shaping circuit 2 outputs, it is just as the remote control in the prior art, can be used to the necessary datas such as carrier frequency of measurements and calculations such as the remote signal that receives, and they are stored in (not shown) in the memory, and can be used to this remote signal of data reproduction according to the memory storage.
For this remote signal of can regenerating faithfully, even this remote signal is also can regenerate faithfully when having this type of available carrier wave in unique logic decision, here said unique logic decision just as such what some European countries adopted, the rising of pulse signal and decline are judged as " 1 " and " 0 " respectively in a predetermined period T, design the studying method of memory remote control device according to first preferred embodiment of the present invention as described below.
Microcomputer 3 comprises an input port 4, directly delivers to input port 4 by the remote signal that photodiode 1 receives; A decision maker, whether being used for according to the remote signal of judging whether this reception from pulse signal of shaping circuit 2 output and envelope signal is to have adopted the remote signal that does not have carrier wave of unique logic, be a kind of remote signal of specific format promptly; A storing apparatus, come remote signal is converted into data with it, and according to the remote signal that is input to input port 4, decision maker point out the remote signal that receives be under the situation of remote signal of specific format, such data-storing in memory; And regenerating unit that is used for according to the remote signal of the data of memory storage, this specific format of regenerating.
Especially narrate the running that the studying method of memory remote control device of said structure is analyzed the remote signal that does not have carrier wave that adopts unique logic decision now with reference to the flow chart of the waveform of Fig. 2 and Fig. 3.The logic of the remote signal that Fig. 2 (A) expression receives; Fig. 2 (B) represents the remote signal of this reception; Fig. 2 (C) expression is by the pulse signal of shaping circuit 2 shapings becoming pulse; Fig. 2 (D) represents envelope signal; The remote signal that Fig. 2 (E) expression has been reproduced.
This shaping circuit that wherein includes single-shot trigger circuit is exported the pulse signal of the predetermined pulse width shown in Fig. 2 (C) according to the rising of the remote signal of the reception as Fig. 2 (B) shown in, and exports and the rising of this pulse signal is synchronously risen but the envelope signal that descends under a non-existent situation of this pulse signal of scheduled period.
As indicated above, be the rising of the remote signal that receives because this shaping circuit 2 detects, so this shaping circuit 2 will not detect the decline corresponding to the logical zero of this remote signal.
Therefore, in first preferred embodiment of the present invention, shown in the flow chart of Fig. 3, at step S1 during when the input of this signal and after this signal input, whether generation step S2 judges between a high period at envelope signal a pulse signal is arranged at step S2.If the pulse signal number that exists between the result of determination of step S2 is pointed out high period at envelope signal is not one, promptly have a plurality of pulse signals, this just means that the remote signal of this reception is not the remote signal of specific format and remote signal with carrier wave, therefore flow process proceeds to S5, carry out a kind of common storage operation identical at step S5 with prior art, thereby storage is such as the such data of carrier frequency according to pulse signal and envelope signal acquisition in memory, and this flow process finishes then.
On the other hand, if the result who judges in step 2 points out, between the envelope signal high period, only there is a pulse signal, this is the remote signal of specific format with regard to the remote signal that means this reception, it promptly is the remote signal that does not have carrier wave that adopts unique logic decision, therefore flow process proceeds to step S3, is directly inputted to the low level T in period of waveform shown in Fig. 2 (B) of microcomputer 3 input ports 4 in this step measurement 1, T 2, T 1, T 3, and they are converted to data.At the step S4 that follows, the data that storage directly measures from this remote signal in memory, meanwhile as prior art according to envelope signal and pulse signal the data-storing that is obtained in memory, then this flow process finishes.
As indicated above, under specific format remote signal situation, prepare this data according to the remote signal of the input port 4 that is directly inputted to microcomputer 3, then they are stored in the memory.
When carrying out the regeneration of remote signal, shown in Fig. 2 (E), that rises subsequently from remote signal constantly, at each low level T in period of memory storage 1, T 2, T 1, T 3Before, remote signal is descended.In other words, according to prior art shown in Figure 180, after the scheduled time β after remote signal rises, remote signal is descended, and the decline of just discussing now according to the remote signal of the preferred embodiments of the present invention is from that time that remote signal rises subsequently, at each low level T in period of memory storage 1, T 2, T 1, T 3Before, sequentially produce.
In this way, shown in Fig. 2 (E), the remote signal of this regeneration meets the remote signal of the reception of waveform shown in Fig. 2 (B) faithfully, therefore, different with prior art system shown in Figure 180, the decline of the signal of this reception also can be regenerated exactly.
Like this, according to the above embodiment of the present invention, because under the remote signal situation of specific format, data are directly analyzed and be converted into to this remote signal before in being stored in memory, and according to the data of memory storage, this remote signal then is reproduced, so, according to the prior art system that only converts remote signal to data according to envelope signal and the pulse signal remote signal of unrenewable this specific format so far, just can be regenerated faithfully expediently.
Referring now to Fig. 4, it represents the circuit block diagram according to the learning control device of second preferred embodiment of the present invention, receiving circuit of reference number 11 expressions, be used to receive the infrared remote-controlled signal of the remote control (not shown) emission of learning from a quilt, and be used for after its waveform is by shaping, it being outputed to a microcomputer 15; Key loader of reference number 12 expressions; Reset circuit of reference number 13 expressions; Reference number 14 expression static random-access memories (S-RAM) are used to store the data of being handled by microcomputer; Memory control circuit of reference number 16 expressions is used to control and 14 relevant the writing and read operation of static random-access memory; Buzzer of reference number 17 expressions; Reference number 18 light-emitting diodes of expression (LED) show, are used for when listening of relevant operation sequence step aspect is provided and as seen indicates to the operator will be by storage the time by described mode hereinafter from the remote signal of the remote control of being learnt; Transtation mission circuit of reference number 19 expression, it comprises the light-emitting diode of the remote signal that is used to send storage and its drive circuit.
For example, when the remote signal of waveform shown in Fig. 5 (A) is input to receiving circuit 11, receiving circuit 11 gives microcomputer 15 outputs two signals, one is the pulse signal of the waveform shown in Fig. 5 (B), it is that the monostable multivibrator that triggers from responding this input signal rising edge is exported, another is the envelope signal of waveform shown in Fig. 5 (C), it is under the time interval of this pulse signal has prolonged situation greater than the value of a predetermined period α, descend after the predetermined period α after the rising edge of the most last pulse of this continuous impulse signal, and the rising edge of the next pulse signal subsequently of response and rising.
Microcomputer 15 has the function as a decision maker will narrating later on, calculates with microcomputer 15 by following formula, for example calculates the carrier frequency f of the remote signal of reception according to pulse and envelope signal:
f＝（N-1）/[t 1-（t 2+α）]
T wherein 1The beginning of expression envelope signal rises to a period between the rising that the next one of envelope signal continues, t 2In a period between the rising that expression continues from the next one that drops to envelope signal of envelope signal, N is illustrated in t in period 1The pulse signal number of Cun Zaiing during this time.
In such a way, microcomputer 15 is converted into data according to pulse signal and envelope signal with the remote signal that receives in the mode that is similar to prior art, then with this data-storing in static random-access memory 14.
Can learn any remote signal in order to make learning control device, a kind of remote signal wherein is the remote signal such as generally the code of certain bits just changes when key of each operation that some European countries adopt, another kind of remote signal is the common remote signal that does not have code change, design the learning control device according to second preferred embodiment of the present invention as described below.
Learning control device according to second preferred embodiment of the present invention comprises a decision maker, it is during storage state, and according to this by first key operation received the remote signal of the remote control of study and second mutual incongruent situation of a remote signal that key operation received according to it under, can inquire about each code of these two remote signals, so that judge whether it is the remote signal of the code of one of them certain bits when operating this key with regard to a kind of like this form of variation at every turn, thereby in the remote signal that receives is one wherein under the situation of the remote signal of this form that just changes of the code of certain bits, just the remote signal that accords with this form can be stored in the static random-access memory 14.
Now will be special with reference to comprising that the flow chart of Fig. 6 of Fig. 6 A and Fig. 6 B is described in the operation that takes place during the storage state.
In beginning, infrared light send window and the infrared light receive window according to the learning control device of the embodiment of the invention of now just discussing of the remote control that a quilt learns will be set Face to face, so that before storage operation beginning, the remote control that the remote signal of infrared light form is learnt from quilt inputs to the learning control device according to the embodiment that is now just discussing.
Then, be arranged on storage state for making learning control device, at step m 1A use/storage switch is arranged on stored position, so, at step m 2Operate a key that requires the learning control device of storage.Along with the operation of such key, at step m 3Produce an electronic voice signal, point out that this remote control is in a kind of state that is ready to receive remote signal.
By operating the key of the remote control that this quilt that will store learns, at step m 4Import first remote signal A, and after remote signal A is converted into data, at step m 5Along with two electronic voice signals of luminous generation of light-emitting diode (LED), the input operation of asking the next one to continue to indicate said first process to finish.Then, at step m 6Unclamp key a period of time of this remote control learnt and these two operations of this learning control device.
At step m 7, by the same key of operate learning remote control once more, at step m 8Produce an electronic voice signal, indicate this learning control device to be in the state that is ready to receive remote signal.By that key of the remote control learnt of the operation quilt identical once more, at step m with this key of learning control device 9Can import second remote signal B.
Then, at step m 10Contrast first and second remote signal A and B, whether meet mutually to judge them.If they meet mutually, just mean that this remote signal is such a type of code change that does not have certain bits when belonging to this key of each operation, just be the general remote signal of using, so at step m 11Store this remote signal B, then at step m 12Along with electronic voice signal of luminous generation of light-emitting diode, finish to indicate this storage, thereby at step m 13Discharge the key of this operation.
The operation of the aforesaid remote signal that is used to the to store general employing situation with the learning control device of prior art basically is identical.
Yet, according to second preferred embodiment of the invention, if at step m 10Judge that first and second remote signal A and B do not meet mutually, will inquire about each code of first and second remote signal A and B, and successively at step m 14And m 15Make judgement separately, belong to this type of the code change that a certain bits is wherein arranged or belong to this type of the code change that two certain bits are wherein arranged to determine this remote signal.
If at step m 14Judge that this remote signal is this type that belongs to the code change that a certain bits is wherein arranged, then at step m 16Store these first and second remote signal A and B the two, then at step m 12" along with the luminous generation electronic voice signal of light-emitting diode, finish with the indication storage, thereby at step m 13Discharge the key of this operation.
On the other hand, if at step m 15Judge that this remote signal is this type that belongs to the code change that two certain bits are wherein arranged, then at step m 17Along with two electronic voice signals of luminous generation of light-emitting diode, with the input operation of asking to be repeated.Like this, by at step m 18The temporary transient key that discharges an operation, and pass through at step m 19Operate the same key that this requires the learning control device of storage once more, at step m 20An exportable electronic voice signal is to be in the state that is ready to receive remote signal with the indication remote control.By this key of the remote control learnt of the operation quilt identical once more, at step m with this key of learning control device 21Can import the 3rd remote signal C.
Then, at step m 22For first, second and the 3rd remote signal A, B and C, decision making once more, whether belong to the such remote signal that wherein has two certain bits codes to change to determine them.If at step m 22Result of determination points out that they are to belong to wherein specific two these types that changed, then at step m 23Prepare the remote signal D of the 4th a less important output after the 3rd remote signal C.In other words, because this remote signal that has two certain bits to change be as previously described, first and second of remote signal with 00,01,10,11,00,01,10,11,00 ... this remote signal that changes of this mode rule, so can be easily to the 3rd remote signal, determine the remote signal D of this 4th less important output, thereby be ready to the remote signal of the 4th less important output from first of such reception.
On the other hand, if at step m 22Result of determination points out that they are not two these types that certain bits has changed that belong to wherein, then at step m 25Produce four electronic voice signals along with the flicker of light-emitting diode, to inform the operator error has taken place, thereby should operate this key once more.
All will be for each key that requires to store at step m 26Repeat above-mentioned steps, then this storage EO.Then, at step m 27The use of learning control device/storage switch is moved on to the use location.
As previously mentioned, during storage state, comparing according to key operation receives by the first time of the remote control learnt remote signal with according to the signal that second time of the remote control of being learnt, key operation received, under the situation that these two remote signals meet mutually, just as the situation of prior art system, store these remote signals, but under two mutual incongruent situations of remote signal, will inquire about each code of these remote signals, so that can judge when whether belonging to this key of each operation this type that certain bits code wherein just changes.If they belong to this type, meet such remote signal and just stored.Therefore, the remote signal of general use can not only be as the situation of prior art system, stored, and the remote signal of using such as some European countries that the certain bits code change is arranged can be stored.
Be noted that and regenerate and send the remote signal that this has deposited in the mode that is similar to the prior art system.Belong under such situation that the certain bits code change is arranged in this remote signal, just regenerate when operating this key at every turn and send the remote signal that this has the certain bits code change.In other words, in aforesaid second preferred embodiment of the invention, for the such remote signal that wherein has specific unitary code to change, alternately send remote signal A and B when operating this key at every turn, for the such distant signal that specific two code change are wherein arranged, in turn and periodically send remote signal A, B, C and D when operating this key at every turn.
Be noted that equally in aforesaid second preferred embodiment of the invention, when remote signal belongs to this type that specific two code change are arranged, described the accurate judgement that when receiving the 3rd remote signal, takes place.Yet, also can be designed as, when only receiving second remote signal or only receiving the 4th remote signal, carry out this judgement.
Like this, according to second preferred embodiment of the present invention, the remote signal of the remote control that the quilt of first reception is learnt and the remote signal of second reception compare, when these two remote signals meet mutually, just as the situation of prior art system, store these remote signals, yet when these two remote signals do not meet mutually, then to inquire about each code of these remote signals, this type of certain bits code change just be arranged when whether belonging to this key of each operation so that can judge them.If they belong to this type, then deposit in and meet such remote signal.Therefore, not only may learn the general remote signal of using, and with the remote signal of the type that also may learn wherein to have the certain bits code change.
To narrate learning control device now according to third preferred embodiment of the invention.The waveform of various signals that is used to explain its operating process is identical with waveform shown in Figure 5 with Fig. 4 about second preferred embodiment of the invention respectively.Therefore, for the sake of simplicity, with details and the operating process thereof that no longer repeats according to the learning control device of third preferred embodiment of the invention.
Yet according to the 3rd embodiment of the present invention, the storage mode of being carried out by learning control device is to finish in the mode of the flow chart as shown in figure 11 that below will describe.Will be by the following learning control device that designs according to third preferred embodiment of the invention, so that it produces the said RC-5 remote signal that adopts such as some European countries, such remote signal that a specific variation is just arranged when being each operating and remote controlling device, just, begin from remote control mode during this key of every operation the 3rd just with 0,1,0,1 ... such remote signal of changing of mode.
Figure 12 represents the remote control mode of RC-5 signal.This remote control mode comprises 14, i.e. two start bits, a control bit, five system address positions and six command bits, as shown in figure 13 each said position comprise occupation efficiency be 25% and the cycle be about 32 pulses of 1.7 milliseconds.
Equally, as shown in figure 14, rise on every the center and every center decline corresponds respectively to logic level " 1 " and " 0 ".
In such remote control mode, initial two is that start bit is set to; " 1 ", next control bit subsequently are called as " counter-rotating position ", can reverse between logic level " 0 " and " 1 " when it belongs to the same keys of a remote-controlled transmitter of each operation such one type.
The remote signal of the type of certain bits code counter-rotating is just arranged when learning this this key of each operation as indicated above, promptly learn said RC-5 signal, design learning control device as described below according to the 3rd preferred embodiment.
In other words, arrange, make RC-5 signal shown in Figure 12 classification become a plurality of two or three s' grouped data, so that can store as classification number data (number number of classification).
These grouped datas are understood by the form of figure, and can be divided into basically as Fig. 7 (A) to four kinds shown in Fig. 7 (D), and can regard 14 remote signals shown in Figure 12 as the combination of these four classification figures 1 to 4.
Can be with t in foregoing period 1(being carved into the period between the rising constantly that the next one continues during from initial rise of envelope signal) and pulse number N(are at t in period 1In the number of the pulse signal that occurs) stipulate each in these four the classification figures 1 to 4.
These four as Fig. 7 (A) to the classification figure 1 to 4 shown in Fig. 7 (D) respectively by N 1, t 1a; N 1, t 1b; N 2, t 1b; And N 2, t 1cRepresent they umber of pulse N and period t 1
Shown in Figure 13 as reference, pulse number N 1And N 2Be respectively 32 and 64, and period t 1a, t 1bAnd t 1cIn each all be period according to the carrier frequency of remote signal regulation.
Carrier frequency mentioned above changes with the type of remote-controlled transmitter, and may be extended to a wide frequency range, so, in the 3rd preferred embodiment of the present invention, its classification figure is divided into as Fig. 7 (A) to 12 type (4 * 3=12) shown in Fig. 7 (L), thereby as shown in Figure 8, the carrier frequency of can classifying is f 1, f 2And f 3Three groups of remote signals.
Like this, above-mentioned classification figure 1 to 4 correspondence carrier frequency f shown in Figure 8 1; Classification figure 5 to 8 correspondences carrier frequency f shown in Figure 8 2; 9 to 12 corresponding carrier frequency f of classification figure 3
Therefore, the t in period that can have the RC-5 signal of carrier frequency shown in Figure 8 according to remote signal 1Each particular value and umber of pulse N, as among three set of carrier frequencies any four the classification figures combination discern.In other words, the remote signal of reception can take to classify among figure 1 to 4, classification figure 5 to 8 and 9 to 12 these three combinations of classification figure one.
For the remote signal classification that receives being become among 12 classification figures 1 to 12, the microcomputer that uses in the practice of third preferred embodiment of the invention uses a read-only memory (ROM storing apparatus), wherein stores for the remote signal classification that receives is become the t in period that one of 12 classification figures provide the foundation 1Data with pulse number N.In fact, owing to t in period 1Be subjected to the influence of carrier frequency, thus give in the practice of third preferred embodiment of the invention period t 1An about 3.125%(=1/32) therefore tolerance limit, according to this carrier frequency, may become two set of carrier frequencies to the remote signal classification that receives.In the case, judge that with most a remote signal that receives is categorized into most set of carrier frequencies.
As mentioned above, this microcomputer with conversion equipment function can be categorized into one of 12 classification figures to the remote signal that receives, so convert it among the classification number data specific one, number number of one of the figure of just classifying so long.
This same key of operation is noted that as long as just can be exported this same code at a predetermined time-out after period.Yet, as shown in Figure 9, a time-out between previous code and the code thereafter being categorized into one of these classification figures period by being similar to mode mentioned above, can store it as the classification number data.
Under the situation of RC-5 signal, because the just counter-rotating of code of certain bits during each this key of operation is so the classification number data that the remote signal that is produced by first key operation by conversion obtains may be inconsistent with the classification number data that the remote signal that is produced by second key operation by conversion obtains.By this viewpoint, in the 3rd preferred embodiment of the present invention, carried out design hereinafter described, to solve the counter-rotating of RC-5 signal controlling position.
The classification number data (classification number number) that Figure 10 represents the part of start bit, control bit, system address position and is categorized into above-mentioned classification figure.Figure 10 also represents to make the corresponding to figure of counter-rotating of above-mentioned classification number data and control bit.Because (E), (F) and (G), (H) shown in Figure 10 taked identical figure respectively, so be readily appreciated that, six figures (A) to (F) shown in Figure 10 have been enough.
As an example, in the classification number data as 10(A) shown in be expressed as at 1,3,1 o'clock, the classification number data of reversing under the situation of control bit counter-rotating can be expressed as 1,1,3 shown in Figure 10 (B).Similarly, be expressed as at 1,3,2 o'clock in the classification number data shown in Figure 10 (C), the classification number data of reversing under the situation of control bit counter-rotating can be expressed as 1,1,4 shown in Figure 10 (D).
Therefore, in case given classification number data of being operated the remote signal of generation by this key for the first time can be discerned because the result of operation second time of this key makes the classification number data of this counter-rotating that control bit reversed.
By above-mentioned viewpoint, play the classification number data formula makeup of counter-rotating and put the microcomputer 15 of effect, can make the classification number data formulaization of counter-rotating according to these figures, in the classification number data of counter-rotating, according to the classification number data of the remote signal that key operation the produces first time, this control bit reverses.
Be noted that classification number data, even its control inversion also keeps identical in classification number data shown in Figure 10 back.
The memory operation is taking place so that during depositing the storage state of remote signal in, microcomputer 15 also as the first time key operation result this counter-rotating of having reversed of the certain bits of remote signal the classification number data and by the second time remote signal that key operation produces the classification number data compare, and when these two classification number data meet mutually, it is deposited in the static random-access memory.
In the time will regenerating this remote signal, from static random-access memory 14, read this classification number data, after usefulness was handled with the opposite mode of above-mentioned classification processing in fact, this remote signal of regenerating sent then.
Like this, utilized microcomputer 15 according to the learning control device of third preferred embodiment of the invention, microcomputer 15 has following function: a storing apparatus, and wherein storing for remote signal being converted into the classification number data provides the grouped data on basis; A conversion equipment is used for according to give the remote signal classification that receives so that the classification number data to be provided in the grouped data of storing apparatus; The classification number data formula makeup of a counter-rotating is put, and is used for according to the classification number data formulaization of the classification number data (certain bits of classification number data is wherein reversed) that are converted the device conversion with this counter-rotating; And a comparison means, be used for during the storage state that can deposit remote signal in, corresponding to according to a key the first time remote signal that operation receives counter-rotating the classification number data and corresponding to according to a key the second time remote signal that operation receives the classification number data compare.The mode of operation of microcomputer 15 is, when meeting mutually, along with an output in response to comparison means deposits these classification number data in the static random-access memory in when the classification number data of the counter-rotating of operating for the first time corresponding to this key with corresponding to the classification number data that this key is operated for the second time.
