Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a rhythm pattern input verification device that verifies and determines whether an input rhythm pattern is correct or not.

<Prior art> For example, in the case of car door lock devices, the current common method for unlocking the door is to insert a key and turn it, but this type of device is not suitable for people with disabilities such as those with hand disabilities. It is difficult to turn the key, and there are also systems in which code numbers are input using push buttons, but this has the problem that children can easily play tricks on it.

For this reason, a predetermined rhythm pattern is input using Morse code using a single signal input switch, such as the length of ON-OFF times, etc., and it is determined whether the input pattern is correct or not. A system for unlocking the door has been proposed (Japanese Unexamined Patent Publication No. 190877/1983).

However, this system looks at the absolute time interval between each input signal that makes up the input rhythm pattern and checks whether the input pattern matches a predetermined rhythm pattern. In such an input pattern matching method, for example, if the input time for a rhythm pattern becomes shorter as the operator gets used to it, even if the same rhythm pattern is input, the rhythm pattern pattern when operated for the first time may be different as shown in Figure 1. The time interval L1 between each input signal of
Compared to L4, L'1 to L'4 between each input signal of the rhythm pattern input when getting used to it is shorter, and the input signal interval time is different, so there is a risk that different judgments will be made when comparing with a predetermined rhythm pattern. However, there is a problem in that it is not possible to accurately identify whether the input signal is correct or incorrect.

<Object of the invention> The present invention has been made in view of the above circumstances, and
After normalizing the rhythm pattern based on the input pulse signal interval, each input signal interval of the normalized rhythm pattern is converted into an integer ratio to a preset reference interval value, and each input signal interval of the input rhythm pattern is converted into a simple By calculating the numerical value as a string and then comparing it with a predetermined rhythm pattern to judge whether it is correct or incorrect, it is possible to accurately judge whether the input rhythm pattern is correct or incorrect, without being affected by the operator's inexperience or unfamiliarity. The purpose is to provide a good rhythm pattern input verification device.

<Structure of the Invention> As shown in FIG. 2, the present invention provides an input means for inputting a rhythm pattern based on pulse signal intervals by continuously operating a plurality of times to generate pulse signals in time series, and this input means. normalizing means for linearly expanding and contracting each pulse signal interval input from the rhythm pattern so that the sum of the pulse signal intervals in the rhythm pattern matches a preset reference value; A conversion means converts the set reference pulse interval into an integer ratio, and the numerical sequence obtained by this conversion means is compared with the numerical sequence of a predetermined rhythm pattern for load driving, and when it is determined to be correct, the load driving signal is output. and an input signal determining means for outputting.

<Example> Hereinafter, one example of the present invention will be described in detail based on the drawings.

FIG. 3 is a block diagram showing one embodiment of the hardware configuration of the present invention.

In the figure, reference numeral 10 is an input unit that generates pulse signals in time series and inputs rhythm patterns by continuously operating multiple times, and specifically includes a button switch, a switch for inputting tapping sounds, and a pressure-sensitive switch. It can be a sheet or a vibrating pickup. 20 is an input signal verification processing unit that verifies whether or not the rhythm pattern input from the input unit 10 is correct;
and a microcomputer equipped with RAM24. 30 is an input signal matching processing section 20
This is a load that is driven when an output is received from the input section 10, that is, when the input signal verification processing section 20 determines that the input pattern input from the input section 10 is correct.

Here, the rhythm pattern input verification processing system in the apparatus of the present invention will be briefly described.

Generally, when inputting a rhythm pattern, the operator determines the minimum input interval that is the basis of the pattern, that is, the basic input interval M, and composes the rhythm pattern to be input at an input interval that is an integral multiple of the basic input interval (see Rhythm Pattern A in FIG. 4). However, it is usually difficult to input a rhythm pattern that is correctly composed of an integral multiple of the basic input interval M, and errors in the interval are particularly likely to occur in the minimum input interval part, that is, the basic input interval part (see rhythm pattern in Figure 4). . Therefore, when the input pattern is normalized, the basic input interval part, M1, M2, M3, M4, and M7 shown in the rhythm pattern in Figure 4, may have an error of about 20% with respect to the basic input interval M. There are many. Therefore, when comparing the rhythm pattern with a predetermined rhythm pattern using absolute time intervals as in the conventional method, it is easy to make an incorrect judgment. Therefore, in the present invention, each input interval of the rhythm pattern input is converted into an integer ratio with respect to the basic input interval M, and the input interval of the rhythm pattern input is expressed by an integer.

That is, find n such that nM-0.25M≦M(I)≦nM+0.25M (I=1, 2, . . . ), and use this value of n as each input interval.

For example, when this is applied to the rhythm pattern in Figure 4, the input intervals M1 to M7 are M1=
1, M2=1, M3=1, M4=1, M5=2,
M6=3 and M7=1. Therefore, it is sufficient to provide a preset rhythm pattern for driving a load as a string of integer numbers that corresponds to the rhythm pattern, and if the input rhythm pattern string is compared with that string and the string matches, the load drive is activated. It is designed to output a drive signal.

Next, the specific operation of the collation processing system of the apparatus of the present invention will be explained in detail according to the flowchart shown in FIG.

When the program starts, first, in a standby state, the pulse counter C for counting input pulses is cleared to 0 in step 101. Next, in step 102, it is determined whether an input pulse has been generated or not. When an input pulse is generated by operating the input unit 10, a pulse counter C is incremented in step 103.

Next, in step 104, it is determined whether or not the next input pulse has occurred within a predetermined time T (for example, 2 to 5 seconds). If it has occurred, the process proceeds to step 105, and the pulse interval with the previous input pulse is set to L(C). ) and execute step 103 again. If no input pulse is generated within the predetermined time T in step 104, step 106 is executed to determine whether the value of the pulse counter C is equal to a predetermined set value C1, and if not, the system returns to the standby state again. . If the value of the pulse counter C is equal to C1, it is determined that the rhythm pattern input has been completed, and steps 107 and 108 are sequentially executed to normalize the rhythm pattern input.

That is, in step 107, the total pulse interval L(I) is determined based on the stored data of each pulse interval L(I).
The total SL of is calculated using the following equation (1).

SL= _cl 〓 ^I=1 L(I) ...(1) Next, in step 108, the normalized pulse interval M(I) of the input rhythm pattern is calculated using the total SL obtained in step 107 as follows (2) ) Calculated using the formula.

M(I)=A×L(I)/SL(I=1, 2..., C1) ...(2) However, A is a normalization constant Once the normalization process of this rhythm pattern input is completed, next The process moves on to integer conversion processing of the pulse interval M(I).

First, variables I and N are initialized by executing step 109, setting N=0 and I=1, and then N is incremented in step 110. and,
By executing steps 111 and 112, the lower limit value M1 and upper limit value M2 of the pulse interval M(I) are determined using the following equations (3) and (4).

M1=N×M−0.25M ……(3) M2=N×M+0.25M ……(4) However, M is the preset basic input interval Next, in step 113, check whether M(I) is greater than or equal to M1. If M(I)≧M1, the process proceeds to step 114, where it is determined whether M(I) is less than or equal to M2, and M(I)≦
If it is not M2, the process returns to step 110, increments the variable N, and repeats the execution up to step 114. Then, when the conditions of steps 113 and 114 are both satisfied, it is determined that M1≦M(I)≦M2, and by executing step 115, the value of N at that time is re-entered into M(I), and the pulse interval M( Finish the integer conversion of I). During this integer conversion process, when M(I) has a value that satisfies N×M+0.25M<M(I)<(N+1)×M−0.25M, the step
If M(I)≧M1 is not satisfied in step 113, it is determined that regular input is not being performed, and the process is ended and the process returns to the standby state, so that the verification judgment can be made more accurately.

When the execution of step 115 is completed, the number of pulse intervals converted into an integer is checked in step 116. That is, it is determined whether I=C1 or not, and NO (I≠C
In case 1), increment I in order to convert the next pulse interval M(I) into an integer (step 117),
Clear N (step 118) and step again
Execute 110 or less. YES at step 116 (I=C
If the determination in 1) is made, it means that the integer conversion of all pulse intervals M(I) (I = 1, 2...C1) has been completed, and the process moves on to determining whether the input rhythm pattern is correct or incorrect. .

That is, step 119 is executed and I is initialized so that I=1. Next, in step 120, it is determined whether or not each pulse interval M(I) of the input rhythm pattern matches the pre-registered pulse interval MM(I) of the rhythm pattern for driving the load. If there is something missing, it returns to the standby state at that point. When it is determined in step 120 that M(I)=MM(I), the process proceeds to step 121, where it is determined whether I=C1, and when I<C1, I is incremented in step 122, and the process proceeds to step 120. Returning to step 2, the next pulse interval M(I) is determined.
Then, when it is determined in step 121 that I=C1, all pulse intervals M(I) (I=1, 2, . . .
Regarding C1), since M(I) = MM(I), the input rhythm pattern and the registered rhythm pattern match, and it is determined that the correct rhythm pattern has been input, and the input signal processing is performed by executing step 123. A load drive signal is output from the section 20 to drive the load,
Return to standby state again.

According to such a rhythm pattern input verification processing system, for example, regarding relatively similar rhythm patterns A and B as shown in FIG. Even if there is some error in , it is reliably determined as "111411" and "112311", and the accuracy of determining whether the rhythm pattern input is correct or incorrect can be improved.

In addition, in this example, N×M−0.25M≦M
(I) Integer conversion is performed by finding N such that ≦N × M + 0.25M, but simply M
Integer conversion may be performed by calculating (I)/M and rounding it off.

<Effects of the Invention> As described above, according to the present invention, after normalizing the input rhythm pattern, each input pulse interval is converted into a simple integer ratio based on a predetermined basic pulse interval, and the input rhythm pattern is Since the rhythm pattern is replaced with a string of numerical values and compared, variations in the input pulse interval that tend to occur when inputting a rhythm pattern can be absorbed, and the comparison with the rhythm pattern intended by the operator becomes accurate. Therefore, it is easy to use, and since different rhythm pattern inputs can be reliably rejected and there is no risk of erroneous verification determination, safety in load drive control is improved.

Furthermore, since the rhythm pattern to be inputted is composed of pulse signal intervals, the operator only has to memorize the pattern of the operation intervals of the input means, which is intuitively easy to remember and easy to operate.
