識方式に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides dial pulses sent to two lines by dialing a dial number corresponding to the number desired to be input using a rotary dial telephone on the sending side after a line is connected. This invention relates to a dial pulse recognition method that detects the dialed number on the receiving side and recognizes the dialed number.
一般に、この種のダイヤルパルス認識方式は。 Generally, this kind of dial pulse recognition method.
回線接続後、まず、予め決められた既知のダイヤル番号

従来のダイヤルパルス認識方式では、この既知のダイヤ
ルパルスの時間長と基準値に対する偏差を算出し記憶す
る。これを学習と称する。In the conventional dial pulse recognition method, the time length of this known dial pulse and the deviation from the reference value are calculated and stored. This is called learning.
そして、前記既知のダイヤルパルスに続いて。And following said known dial pulse.

イヤルパルスの時間長を算出し、前記学習で求めた偏差
を用いて未知ダイヤル番−号を判定する。The time length of the dial pulse of the unknown dial number input from the transmitting side to the receiving side is calculated, and the unknown dial number is determined using the deviation obtained in the learning.

パルス応答信号から最後のイ／／シルス応答信号までの
時間長を算出して、入力されたダイヤルパルスのダイヤ
ル番号を判定するので。This is because the dial number of the input dial pulse is determined by detecting the impulse response of the dial pulse and calculating the time length from the first impulse response signal to the last I//Sils response signal.
以下のような欠点がある。It has the following drawbacks.
ダイヤルパルス列の前後には擬似パルスが発生する危険

気通信協会発行の「電話交換・信号方式」第１９４頁に
次のように説明されている。There is a risk that false pulses will occur before and after the dial pulse train. The pseudo pulse is explained as follows on page 194 of "Telephone Exchange/Signal System" published by the Telecommunications Association of Japan on February 2, 1978.
「ダイヤルの初め罠生ずる擬似パルスは、インパルス列
のはじめに電話機のダイヤル接点のみが開き１局線トラ
ンクのＡ Ｉ７レーがまだ応動しないときに生ずる過渡
電流によるものである。The spurious pulses that occur during the beginning of the dial trap are due to the transient current that occurs when only the telephone dial contacts open at the beginning of the impulse train and the AI7 relay on the single-station trunk has not yet responded.
また終りに生ずる擬似パルスは９局線トランクのＣリレ

これを第２図を用いて説明する。The pseudo pulses generated at the end are due to the transient current generated by the blocking wires inserted into the two circuits when the C relay of the 9th station trunk is restored. ” This will be explained using FIG.

列の総時間長を算出するのは同信号６〜１０までの継続
時間長を用いる。This figure shows the relationship between the dial pulse waveform and time when the dial O is turned. Figure 2 (b) 6-1
The 0 signal is an impulse response signal, and the duration of signals 6 to 10 is used to calculate the total time length of the dial pulse train.

に発生するので間層はないが，パルス列の初めに生ずる
擬似パルスは，ダイヤル番号のダイヤルパルスによって
発生したり発生しなかったりする。However, the impulse response signal 6 is a pseudo-pulse that occurs at the beginning of the pulse train, and the impulse response signal 10 is a pseudo-pulse that occurs at the end of the pulse train.
Since the dial pulses for all dial numbers are generated at similar positions, there is no interlayer, but the pseudo pulses that occur at the beginning of the pulse train may or may not be generated depending on the dial pulse of the dial number.

しまう。The deviation is calculated assuming that no pseudo pulse occurs at the beginning of the dial pulse train used for learning. but,
Assume that a pseudo pulse occurs at the beginning of a dial pulse train for an unknown dial number. To determine an unknown dialed number, the time length from the first impulse response signal to the last impulse response signal of the input dial pulse is used, so from the impulse response signal 6 in Figure 2 (b) 7 will be taken up extra time,
If the deviation obtained through learning is used for determination, the dial number will be determined to be one dial larger than the original dial number.
また、学習のダイヤル列の初めに擬似パルスが生じて，
未知のダイヤルパルス列には擬似パルスが生じなかった
とすると，前記した判定結果のまったく逆のことがいえ
る。In addition, a pseudo pulse occurs at the beginning of the learning dial string,
Assuming that no pseudo pulses occur in the unknown dial pulse train, the exact opposite of the above-mentioned determination result can be obtained.
本発明の目的は，ダイヤルパルス列の前後に擬似パルス

にある。An object of the present invention is to provide a dial pulse recognition method that can correctly recognize a dial pulse train even when pseudo pulses occur before and after the dial pulse train.

特徴とするダイヤルパルス認識方式が得られる。According to the present invention, in the recognition method in which the dial pulse generated by the transmitting telephone is recognized on the receiving side after one line is connected, the impulse response signal of the input dial pulse is detected, and the impulse response signal is converted to the average impulse speed. A dial pulse recognition method is obtained which is characterized in that the dial pulse is divided into sections using , and the result of counting the number of sections is determined to be the dial number of the unknown input dial pulse.

Select the pulse closest to the reference value that falls within the interval. If the secondary pulse cannot be selected (there is no pulse within the range), then pulse 6 is considered a pseudo pulse, and if pulse 7 is used as the start pulse, pulse 8 falls within the range of the first section. .
