Description

The information transmission system with frequency-independent

The present invention relates to the information transmission technology, particularly about a kind of transmission system of code.

People had proposed many information transmission systems. For example, the name that is presented to Brown Jr. is called the 3rd, 366, No. 737 United States Patent (USP)s of " asynchronous starting---stop the message switching center of telegraph channel "; The name that is presented to Batin is called the 3rd, 627, No. 951 United States Patent (USP)s of " by the asynchronous communication system of data processing equipment control "; The name that is presented to the people such as Eggi-mann is called the 3rd, 633, No. 172 United States Patent (USP)s of " method and apparatus of address coding signal transmission "; The name that is presented to the people such as Closs is called the 3rd, 796, No. 835 United States Patent (USP)s of " the tdm data exchange system of introducing a kind of asynchronous multipling channel "; The name that is presented to the people such as Kuemmerle is called the 3rd, 988, No. 545 United States Patent (USP)s of " transmit the method for information and be used for carrying out the multiplexer of this method "; The name that is presented to Pederson be called " the loop carrier system that is used for telecommunications and data service " the 4th, 154, No. 983 United States Patent (USP)s and the name that is presented to the people such as Fourcade are called the 4th, 390, No. 985 United States Patent (USP)s of " sychronisation that is used for the grouping digital data transfer ".

The present invention relates to a kind of system that transmits information, wherein information is comprised of the particular message cell-in-series that exceeds one group of possible unit, (for example, by a message word that exceeds alphabetic(al) 26 letters and form) and comprise the step of the cyclophysis ratio of each unit that defines this group. Then, this message is transformed to the burst that a reference frequency signal and a series of information signal form, and above-mentioned each information signal has a frequency that differs by cyclophysis ratio and the reference signal frequency of above-mentioned definition. Then, this message is sent out. Utilize a receiver, the signal that relatively receives is determined the time interval in the signal, and compares these cyclophysis ratios, obtains defined cyclophysis ratio, and then this group signal exchange is original message.

This system can utilize a number of units word computer with the form realization of equipment at an easy rate, and comprises that a transmitter and a receiver are to implement this method.

Owing to used a cyclophysis ratio, thus the variation on no matter from a message to the frequency of another message, and no matter also the even skew of each frequency, this message can transmit and identify. This system has following advantages:

Message in this system---rate code and frequency-independent, therefore, cross spectral neatly.

Because a message is only identified by a specific cyclophysis ratio, can transmit in higher or lower frequency, therefore, the message of this system---rate code consists of a kind of flexibly system.

This system provides the very large free degree in hardware design. This system allows different equipment when transmitting the message of same ratio coding, communicates with higher or lower frequency.

This system makes high-frequency equipment and low-frequency equipment compatible mutually.

Utilize the message of this system---rate code, the recipient of a broadband device can understand the high and low frequency message of the transmitter that transmits with the same ratio coded message.

Because this transmitter can transmit a certain specific rate code message in higher or lower frequency, this system provides a kind of flexibly transmitter device.

Therefore, the transmitter of this system also can transmit information in other mode, and namely the form with the audibility sound of rate code transmits, and is directly translated by true man's recipient. When making in this way, this system receiver equipment can omit. This specification has also disclosed a clock of the tone transmitter that comprises that composition is such and some examples of a voltmeter.

This system and each advantage thereof can obtain the most sufficient understanding by the reference description taken together with the accompanying drawings, and in following accompanying drawing, identical label represents identical parts.

With reference to each accompanying drawing, particularly Fig. 1, method of the present invention can be understood from the description below with reference to Fig. 1.

Although should be noted that what draw in the drawings is square-wave waveform, its described principle can be applied to the periodic waveform of any shape.

System of the present invention or method are utilized two frequency waveforms, for example waveform W shown in Figure 1_RAnd W_S(1) the cyclophysis ratio I between identifies a specific message or item of information (for example letter " A ") from a table of certain message. These frequencies can be decided to be f to reference frequency_R, can be decided to be f for signal frequency_S Then this ratio I can define with following formula:

I = \frac{f_{S}}{f_{R}}

The cycle T of utilizing a signal wave is this definition of inverse of its frequency

Following formula becomes:

I = \frac{T_{R}}{T_{S}} = \frac{D_{R}}{D_{S}}

D in the formula_RAnd D_SExpression waveform W_ROr W_SDuration half period.

Each ratio in ratio table can refer to given a kind of different particular message. Refer again to Fig. 1, two waveform W_RAnd W_S(1)Can be defined as a ratio:

I_{S (1)} = \frac{T_{R}}{T_{S (1)}}

By ordinary circumstance, any waveform W_S(N)Can be defined as a ratio:

I_{S (N)} = \frac{T_{R}}{T_{S (N)}} = \frac{f_{S (N)}}{f_{R}}

And, by defining a message elements, for n message, then by two waveform W_RAnd W_S(N)Produce this N message elements M (N). If I in table_S(N)Value equal I_K, this I_KBe designated as a specific message elements M_K, then M (N) equals M_K。

Fig. 4 is a kind of like this normalization table, as a concrete example, supposes that we wish to go to transmit a message with English alphabet. Then, we can make this form:

Like this, can use W for " Y " message elements_RFrequency be 10KHz and W_SFrequency be two waveform W of 20KHz_RAnd W_SCarry out conversion. Should be noted that above-mentioned " Y " can also come conversion with 1KHz and 2KHz or 1.13MHz and 2.26MHz.

(certainly, in the receiver of this reality of system, any rate value in an above-mentioned accuracy rating all can receive. )

Waveform W_RAnd W_S(1)Deng can transmitting continuously as shown in Figure 2, even the single cycle of waveform also can transmit as shown in the figure. Yet, in most of concrete instances, waveform W preferably_R、W _S(1), in order to easily its equivalence value with lower accuracy is realized detecting in lasting a plurality of cycles. But, for using the half period D represented such as Fig. 3_R、 D _S(1)、D _S(N)The duration of this weak point is not wanted, and in addition, each message elements is to represent by the defined ratio of formula that represents here in this case.

Fig. 5 represents the step of practical methods of the present invention with the form of the computer flow chart of routine. Since 12, the first step 14 is to set up message ratio (MI) table (step 14). Next step 16 is the concrete message elements M of input₍₁₎……M _(N)(the Table I input alphabet above for example utilizing and some spaces " being now ... auxiliary ... ") in step 16, also selects some corresponding ratios from the MI table of step 14. According to the input of step 16, in the end step 18 produces W_R、W _S(1)Deng, after these steps were finished, operation just was through with in step 20.

Be used for to realize Fig. 5 method transmitter 21 as shown in Figure 6, wherein, input 24 at microcomputer 22 receives each message elements, and (for example passing through keyboard) also selects suitable ratio (this table can be taked the source of form or other any appropriate of rom chip) from install a MI table of 26. Microcomputer 22 is derived some continuous signals as reference waveform and message waveform, and these waveforms are fed to an output 28. For example, these waveforms can be waveform D_R、D _S(1)Duration of half period. Output 28 is connected to programmable waveform generator 30, thereby produces output waveform W at its output 32_R、W _S(1)Deng, this latter's output 32 can connect a kind of suitable transport vehicle, such as transmission line or optical fiber or broadcast antenna.

This transmitter consists of, and utilizes a kind of BBC Type B microcomputer successfully to work. This microcomputer contains 6502 CPU and two 6522 general-purpose interface adapters, and one of them adapter USER VIA has been connected to the upper for the user with the registered permanent residence (USER PORT) of Type B microcomputer. For the more detail flowchart of realizing this special and existing method for optimizing of the present invention as shown in Figure 7.

In this special situation, microcomputer 22 not only can play the effect of microcomputer 22, and deposits the effect that table MI plays table 26 in the RAM of microcomputer in. USER VIA part can be selected operation as generator 30, and wherein output wave is to be masked as the two ends acquisition of the preferred circuit of PB7 and 0V from this commercialization computer with the registered permanent residence (USER PORT).

The flow chart of Fig. 7 comprises a starting command 34, and this order is set up the MI table and got the reference signal D (half period) of a preliminary election in step 40 in step 36, and begins to count down in the logic state of next stages 42 inversion output terminal and to D. Before this counted down end, getting next signal D in function square frame 44 (was D_S(1)Deng), if this is not last D (test square frame 46) that gets, then system responses reselects the process of next D in the indication of square frame 47. If testing 46 answer is "Yes", then the indication of system responses logic block 50 begins last D is counted down, and the indication of response square frame 52, at its output reverse logic, and finishes in step 54.

The flow chart of Fig. 7 and the included step of this program are used for understanding a kind of equipment that the similar rate code " half period ripple " (INTERVAL-CODED " HALF-CYCLE " WAVFLETS) as shown in Figure 3 of passing through to produce transmits message. Can also be summed up as by producing each twice the sort of " half period ripple " (" HALF-CYCLE ") and obtain being similar to those " single periodic waves " (" SINGLE-CYCLE " WAVES) shown in Figure 2. And obtain being similar to the series of Fig. 1 by producing each the sort of half period ripple several times.

Utilize output signal that the system of Fig. 6 and Fig. 7 produces as shown in Figure 8, the output of its center line 32 is by the reference D with Different Logic process_R、D _S(1)And D_S(2)Describing, is to export by their timing relationship.

With reference to Fig. 9, a receiver 60 has wherein been described, this receiver has an input 62, receives from suitable transmission medium, such as the various waveform W of transmission line, optical fiber or antenna by this input_R、W _S(1)……W _S(N) This input 62 is delivered to a waveform duration measuring circuit 64 with these waveforms, and this circuit measuring duration D is also successively with the duration information D_R、D _S(1)Deng being fed to microcomputer 66. A transmission signal W who is substantially similar to transmitter is set_R、W _S(1)Deng MI table 68, computer calculates each ratio, and obtains message elements M from table 68₍₁₎、… …M _(N) These message elements are sent to a suitable outlet terminal 70, such as cathode-ray tube display or printer or both.

The MI table 26 of supposing transmitter 21 has one of accurate rate value, and then receiver should be able to be identified in the rate value that calculates in a certain scope of this exact value as mentioned above. This point can realize by the immediate rate value of procedure Selection or by the contained a certain scope of the MI table 68 in the receiver. Native system adopts at present above-mentioned rear a kind of method, and has the receiver of being applicable to 60, as the following MI table 68 of top given particular message:

Table II message elements ratio border

Etc.

In other words, in transmitter 21, MI table 26 is with message---the form of the duration corresponding relation of ripple is set up, and MI table 68 is cancellation breath---forms of ratio border corresponding relation in receiver 60.

MI in Table I table for example can be 32 state encodings, and wherein each unit that disappears has the identical information content, five binary bits for example, namely from 1 to 32. Can find out obviously that from Table I similarly the MI table also can utilize the message of the codings such as 4 states, 8 states, 10 states and 24 states.

The computer 66 of receiver also can be BBC Type B microcomputer, and this computer is according to the flow chart programming of Figure 10, and its program provides below. In this case, MI table 68 remains among the RAM again.

Receiver 60 is easily to be made of above-mentioned computer, and needs a waveform measurement circuit 64, and a kind of preferred circuit 64 as shown in figure 11.

The components and parts of sort circuit, numerical value and correlation are as shown in figure 11. The circuit of Figure 11 is connected on the I/O mouth of known 1MHz expansion bus of BBC microcomputer. Circuit connector R/NW, the NP of Figure 11, A₀、A ₁、A ₂、O、D ₀、 D ₁、D ₂、D ₃、D ₄、D ₅、D ₆、D ₇Be connected respectively to R/NW, NPGFC, the A of this 1MHz expansion bus with G₀、A ₁、A ₂、1MHz、 D ₀、D ₁、D ₂、D ₃、D ₄、D ₅、D ₆、D ₇And 0V.

In all operations, circuit 64 is used for measuring the moment that each wave form varies appears in incoming wave, and sends this information to microcomputer 66.

At the input R of circuit 64, the ripple W that receives is sent to inverter buffer 71, produces a backward-wave NW at its output, and this backward-wave is once anti-phase again by reverser 73, at the highest significant position D of 16 latch 74₁₅Recover not anti-phase ripple W. Utilize decoder 76, trigger 77, converter 78 and computer 66 to present selectively waveform W or NW, on the other hand, what the LE of latch 74 produced a time correlation latchs waveform LW, and it can be explained with Figure 12. Then, by detecting D₁₅The waveform W of place changes the voltage level of " height " or " low ", computer 66 is carried out following operation: (a) preset LW to high level, (b) appearance of wave form varies among the detection ripple W, (C) height by LW-change to-low level, read of catching from counter 79 74 and latch a yard meter reading, (d) for the not latching accumulator 74 of another time seizure, LW will reset to high level. The clock O that provides (for example from computer 66) removes operational counter 79 and removes Operational Conversion Unit 78 by phase inverter 80. The calculator reading of resulting seizure is at the duration D that receives waveform W in this way_R、D _S(1)Deng on information is provided.

With reference to Figure 10, program is since 82, in step 84, sets up the MI table at its RAM, and for example it copies from a disc driver or other more nonvolatil memory. (in the situation of dedicated receiver, can adopt the form of rom chip). Therefore, at square frame 86, use device 64 is measured the received waveform duration, at square frame 88, according to MI table identification ratio and message elements, and when aforesaid operations is finished, finishes at terminal 89 knots.

Program above the computer utilization is programmed, and each that occurs by wave recording changes the duration that moment removes to measure this ripple. The measuring process of the duration of ripple is described in the timing diagram of Figure 12.

Like this, receiver 60 automatic translation space coding ripples, the message that identification and output transmit, and store these message in order to using afterwards.

With reference to Figure 13, a kind of message storage/searching system 90 of novelty has been described among the figure, this system can between storage-life with later retrieval during with identical or different speed operations, namely the characteristics of system of the present invention novelty are the irrelevant operation principles of itself and service speed.

A kind of wave conversion record/playback apparatus between transmitter 21 and the receiver 60 can be thought to be inserted in by system 90, such as logger 91 a kind of magnetic or light. Although all have different records and the speed of playback with the original records ripple of different cyclophysis ratios and the ripple of rear region retrieval, and do not require transmitter and receiver are made amendment. Because message is rate code, and there is not frequency characteristic, so this operation is possible.

A kind of rational wave form varies record/playback apparatus that uses in system 90 can think that a kind of commercially available magnetic tape deck adds hardware as shown in figure 14. For example, a TEAC (trade (brand) name) A-4300 adds that Maxell (trade (brand) name) XLI35-90B open-reel tape is used for the recording level adjustment, so that at the about 0.6V peak-to-peak voltage of monitoring cable output. Its playback levels adjust at circuit Y o'clock is about the 2V peak-to-peak voltage for a given signal.

To be fed to from the rate code of transmitter 21 the LINE IN input of magnetic tape deck 91, and record (for example at 7.5ips) with speed 1. And with speed 2 playback times (speed 2 can be different from speed 1, for example at 3.25ips), then retrieve the initial rate code ripple that records, and export at the output of the LINE of the tape transport that works in playback mould 92 OUT. This signal is delivered to a buffer, and the reverse input end by electric capacity 94 and 96 to amplifiers 98 of resistance, the non-inverting input of this amplifier applies+biasing of 6V, namely

The part output of amplifier 98 feeds back to its reverse input end by resistance 100 to casing ground and by resistance 102. Another part of output is delivered to differentiator, deliver to the reverse input end of amplifier 108 by resistance 104 and electric capacity 106, the non-inverting input of amplifier 108 applies+the 6V biasing, and the part of its output is fed to casing ground by resistance 110, and feeds back to its reverse input end by resistance 112. Another part output of amplifier 108 is delivered to Schmidt trigger 116 by circuit point Y and electric capacity 114. Schmidt trigger 116 is comprised of MC 1455 timers, its R and V+ point are connected to+5V, its GND is connected to casing ground, its input point TH and TR be connected across by two equal resistance 118 and 120+5V and casing ground between on the mid point of formed divider. The rate code output of Schmidt trigger 116 is fed to receiver 60.

System of the present invention is quite flexible, and can use in a different manner. A kind of mode wherein is to use one group (to be 2494,2497,2500,2503 with one group of width for example by the rate code signal that waits the width incremental difference ... Deng rate code, wherein the actual increment that uses is 3 in below the object lesson). In this MI coded system, it should be noted, if in this group last width be scheduled to and etc. the numerical value of width increment also be scheduled to, the number that a preferred rate code width is then arranged concerning this group, namely for a kind of preferred coded system that transmits fast a random information as shown in Table III.

Table III

The preferred condition number 0.2 8 0.07 16 0.025 32 0.0098 64 0.00404 128 0.00172 256 0.15 10 etc etc of coding

Table III represents respectively specific preferred MI coding. Each of several situations (waiting the width increment)/(minimum widith of this group) is predetermined than all. The preferred number of the rate code width of every kind of situation is respectively 8,16,32,64,128,256 and 10.

The use of Table III can further be explained with following example. Such as, if minimum width and the increment of width are respectively 100 and 20 for this coding, then 8 states (1 message in 8) are encoded to optimized encoding in the Table III, in this case, this group rate code width should be 100,120,140,160,180,200,220 and 240.

An object lesson according to this system, utilize 256 rate code, this system can be coupled to specific receiver 60 by specific transmitter 21 by a kind of suitable transmission medium described above and realize that the programming of its transmitter 21 is carried out with follow procedure:

Table IV message elements DR DS I 223 2,509 2,509 250,9/2,509 3 2,509 2,506 250,9/2,506 8 2,509 2,503 250,9/2,503 26 2,509 2,500 250,9/2,500 27 2,509 2,497 250,9/2,497 15 2,509 2,494 250,9/2,494 43 2,509 2,491 250,9/2,491 254 2,509 2,488 250,9/2,488 33 2,509 2,485 250,9/2,485 53 2,509 2,482 2509/2482...... 192 2,509 1,753 250,9/1,753 92 2,509 1,750 250,9/1,750 250 2,509 1,747 250,9/1,747 38 2,509 1,744 2509/1744 (the MI codings of 256 random pairs)

Wherein each unit in 256 message elements can be arbitrarily designated as some characters and numeral or other numerical data. Permitted in the multi-mode situation, for example this 256 state encodings are particularly suitable for the transmission system of system, the especially private data of transfer of data. Used a kind of random order mode in the MI coding, such one deck complexity that increased as shown in Table IV makes the decoding of this coding more difficult.

256 status messages of in transmitter 21 each being maintained secrecy are a kind of wavelet of rate code according to the MI table transform of encrypting, and each unit in this table in contained a kind of 256 message elements all is assigned to each width in 256 rate code width randomly and uniquely.

In receiver 60, these ripples are detected, simultaneously, according to the 256 state MI coding of identical encryption, be decoded as the original private message of a byte.

Because in this case, the number that conversion is arranged includes 256 factors, and this encryptions MI coding still can constantly change, and therefore, if this coded system is not provided, it is impossible that the MI that goes to guess this encryption encodes. So, for this rate code ripple, even the above-mentioned signal of intercept in the communication port between transmitter 21 and receiver 60 also is not easy to decode the message of transmitting.

By introduce many reference waves in signal wave, this rate code wave system system can be allowed larger frequency shift (FS). In an extreme example, we can select a transmission reference wave adjoining with each signal wave, and are for example following: W_R(1)、W _S(1)、 W _R(2)、… …，W _R(N)、W _S(N), this means for continuous ratio evaluation, can change and revise for the reference of each single message elements. This form allows frequency of occurrences jump between each message elements, and wherein each ratio can be respectively by ripple W_R(1)And W_S(1), and W_S(2)、……W _R(N)And W_S(N)Deng defining.

In addition, method of the present invention and transmitter can be put into practice and carry out with other method, transmission such as information is to carry out with the form of rate code tone, for example use rate code music tone (namely this tone belongs to a kind of scale of music), this tone can be easily identified by true man's listener, and then this listener recognizes the coded message in tone again. On the other hand, the load mode of this information is to be carried out by the MI table of Fig. 4, the method for Fig. 5 and the transmitter of Fig. 6. The tone that sends is how all waveforms. In Fig. 1, represented the waveform that some are suitable. As a concrete example, suppose that we wish to transmit some digital values, then we can set up one as following table with the MI at suitable music interval table:

Table V message elements ratio reftone signal tone

Frequency (Hz) frequency (Hz)-0.7500 512 384. 0.8333 512 463 0 0.9375 512 480 1 1.000 512 512 2 1.125 512 576 3 1.250 512 640 4 1.333 512 682 5 1.500 512 768 6 1.667 512 854 7 1.875 512 960 8 2.000 512 1,024 9 2.250 512 1152

etc.

Fig. 5 represents each step of practical methods of the present invention again. From label 12, the first step 14 is MI tables (step 14) of setting up as Table V. Next step 16 is the special message elements M of input₍₁₎，……M _(N), (the Table V input message elements " " shown in for example utilizing, " 1 ", " 5 " and " 2 ") also select corresponding interval in step 16 from the MI table of step 14. Last step 18 is according to the input generation of step 16 and transmits tone W_R、W _S(1)Etc.. (for example pitch sequences of " 512Hz tone (reftone); 384Hz tone (data tones), 512Hz tone (data tones), 768Hz tone (data tones) and 576Hz tone (data tones) "), after aforesaid operations was finished, the whole step 20 that operates in finished. Current preferred output order agreement is at first to transmit with reference to sound, transmits subsequently a series of information tones. When the contained rate code information of this tone series with comprise that with this information reference information together thus generated tone series is useful, thereby communication can be realized can be decoded the time. The tone that transmits can be by true man's listener translation (certainly also can be by the above-mentioned programming receiver automatic decoding that is operated in a plurality of periodic waves by the contained information of these tones). What also should give attention is to implement in this way a significant advantage of the present invention to be, the music tone of this transmission distinguishes more more reliable than other unmusical ratio tone of listening in euphonic difference by true man's listener. A well-trained true man listener can pick out the tone (rate code tone) that belongs to a kind of scale when identification contains the various output tone of scale. (even children also may find the easily simple music tone sequence of identification, for example difference of identification and " DO-ME-SO " in " DO-ME-LA "). When listening the pitch sequences that transmits, the listener can subjective attention first sound in this sequence as the reference sound " DO " of some music scale, and (for example, identify them according to relevant pitch sequences: " DO " " SO " " DO " " SO " " Re ") identify the pitch sequences that the specific tone on this scale transmits because their ratio.

If MI table is known, and first tone in this sequence also is known as a reference, thereby the listener can translate specific information tone in the pitch sequences that transmits, such as " one ", " 1 ", " 5 ", " 2 ". System of the present invention provides a kind of method of tone output, and in a specific device and system, transmitter can be used as output device work, can also be as a kind of visual replacement scheme that shows.

Belonging to a kind of diatonic scale (whole tone scale) although be used for each specific ratio of Table V, is to belong to a kind of slightly different scale, such as etc. the corresponding ratio of blending scale also can use satisfactorily.

Be further noted that also one of advantage of the present invention is that its operation principle is without frequency characteristic. The group of frequencies that transmits at an other tone equally also can be suitable for Table V higher or produce tone than bass, does not change specific ratio with which. This makes many similar group of frequencies compatible and therefore allow in the Hardware Design the larger free degree is arranged mutually, and makes the transmitter can be compatible mutually in the different frequency scope.

The transmitter 21 of Fig. 5 and Fig. 6 is used to realize said method. For the specific example of a kind of special use of realizing above-mentioned tone (multicycle ripple) method, transmitter consists of with microcomputer 22. Has one group of different messages unit of being correlated with from different music ratios respectively, be that each ratio belongs to a kind of music scale, those intervals shown in the top Table V for example, consist of with a tone generator able to programme (for example pitch processor chip that links to each other with the loudspeaker output), send the audibility tone as generator 30,32 with the form of multicycle ripple as output wave, waveform shown in Figure 1 for example. Specific message elements is from a source, and for example keyboard, memory unit or other circuit are fed to 24 ends of transmitter continuously.

According to the another one example of method of the present invention or system, used transmitter is included in as shown in figure 15 the clock 130, the digital component of this clock Measuring Time and the rate code music tone 132 output time values passing through to transmit. These tones can report time, can also be as the visual replacement scheme that shows. This clock is to utilize a timer that connects 135 to realize, the front end that is used for measuring at above-mentioned transmitter 21 is exported the represented time with numeral. This clock has consisted of and has utilized the timer internal of BBC Type B microcomputer successfully to work as timer 135, and with same microcomputer as microcomputer 22, a kind of concert pitch chip (a SN76489 chip) is linked to each other as programmable waveform generator 30 with the loudspeaker output of same microcomputer, and Table V is based upon among the RAM of same microcomputer as MI table 26. Below a kind of program that is suitable for the microcomputer 22 of present embodiment is listed in, and as sender process III:
