The means 15 consists of a counter 15a, AND gates 15b and 15c, and DFF15d and discriminates the forecast signals of 440Hz and the correct time signal of 880Hz to decide the time signal.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a time signal detection device, and particularly aims to provide a time signal detection device capable of detecting a positive 41 fCe (time signal) without any adjustment without compromising the characteristics of filters, etc. It is something to do.

〈〈〉〈The background image of Ming〉 A clock with an automatic clock adjustment machine V1 adjusts the time by 1 according to the time signal of the broadcast. In Japan, NHK is generally ranked No. 1.
Also, detect the time signal used in 1-2, and use the detected signal to correct the time display at 6-1. L As shown in Figure 1, 4.4 (l fiz forecast 11. bow 7) 1
-j+, sum of 0.1 seconds at intervals of 3 seconds, and 880 Hz positive signal is applied to the body for 1 second, and the signal gradually decays over 2 seconds.1, 〈(IL coming nuclear technology Conventionally, it is detected by a filter for pre-warning and positive news, and the detection signal is used to execute an automatic correction operation. When a filter is used in this way, the filter's q: f frequency 440Hz and 88011z central station W
This has the drawback that it requires adjustment work to obtain the bandpass filter b, which requires a long manufacturing time.

In addition, the filter allows 440Hz and 880Hz to be pre-+1
In the case of 10#Ii Ao Toshi which sends information to 3 and I, there is a time delay in its detection, and this time delay makes it accurate! , 11 Shu 1] There is also the drawback that you cannot turn a snake into a bamboo. In particular, when a mechanical filter is used for the larva 1, 1j7N adjustment, this draining time becomes long.

In order to wipe out these shortcomings, an example is the
As proposed in Publication No. 153, a blooming method without using a filter has been considered. Tokuko Sho 57-4415
The time signal detection device proposed in No. 3 Koshin 1 (No.
A method is adopted in which it is determined whether or not the interval is ij, and a time signal is detected.

<Conventional drawbacks> The time signal detection device described in this publication has a colorless (Th) period tune installed before the start of the time signal, and this colorless -kj
, 401 to find out the time signal based on the detection.

However, even if there is no signal in radio broadcasting, there will still be foreign sounds, and it is difficult to ensure no signal3.Therefore, when using this method, there is a risk of malfunction due to noise, and The drawback is that it is difficult to detect 11200 I.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a time signal detection device that can virtually detect time signals without using a filter. 1 <Summary of the invention> In this invention, the forecast signal No. 1b and the city@ka signal are pushed out by a period measuring means with a fixed period of 11, and the period measuring means is used to push out the forecast signal and the correct news signal. It detects that the same song has continued for a predetermined number of times and has arrived a predetermined number of times, and then crosses the C to detect a time signal.

In addition, the pre-Y1y signal is not supplied to the differentiating circuit 14.

Divide ii;' by 1, 11, t14, and Example 1 can be done as ii4 IJ'x by using the counter 14a and the at-category 14b, without leaving the 31st step I. The Tosei J Hin antipa output from the r antimoon polyshaping circuit 13 is 19 minutes.

．． A clock pulse of 288 K) Lz is applied to the input terminal φ1 by applying the output terminal Q2 to the input terminal φ1.

Counter], 4a is reset 1, when child RKL fall is given, it is reset when HtrM is given. FE counter I-4a is reset at the falling edge of rectangle 1.Pa. Counting starts synchronously.The counter 14a counts 288KIIZ clock pulses, and when the counter 14a increments by 1 or 2, the output terminal Q2 becomes H=ffl.
Therefore, this l (cotton grain 1.τ is elastically reversed and leaks to the input terminal φ1, so at that point the color/ri 14a is counted) 1 production is stopped. Due to this operation, a clock pulse pb of 288 kHz is supplied from the four outputs Q+ of the counter 14a immediately after the fall of the rectangular wave Pa.
Only one pulse Pc having the same pulse width τ1 in one period is taken out at each falling edge of the wave Pa. This pulse is combined with the clock pulse Pb in the AND gate 14b.Therefore, from the AND gate 14b, as shown in the fourth diagram, a pulse l) d which is the same as the clock pulse Pb is generated. One is swallowed.

In this way, a pulse pd with a narrow pulse width is obtained from the differentiating circuit 14 in synchronization with the fall of the rectangular sand p.sub.a.

The period T of this pulse pd coincides with the J low period of the forecast signal.

The differential pulse pd obtained by the differentiating circuit 14 is sent to the period side rectangular means 15, and its period T is determined.

The stage 15 can be divided by the counter 15a, the AND cable 15t), 15c and 1] the flip-flop l5d7.

A: Pd is the counter], 5a's reset terminal 1 is given to 7, 1 is the counter 15a's -

Detects that the number of books has become six.

The timing at which both the output terminals Q5 and Q7 become 11 times 1 is between the time when 80f16194 of the 36 KHz clock pulse is applied and the time when 96 clock pulses of 36 KHz are supplied. Converting this into time, it is the time from the time when 2222 milliseconds have passed since the start of counting until 2.666 milliJ seconds have passed.

In other words, when the F sign from 375 Hy to 450 H2 is input, ANDK 1 5 b id H 1 ri is output. , the output of the AND gate 15b is applied to the theta input terminal of the D-type Flinoff flop 15d.

1 Ri D jr. The output of the flip-flop 15d is applied to the reset t.7ii quintuplet R of the counter 16b. The color/receiver 16b inverts the polarity of the output from the output terminal Q3 and supplies it to the input path element φ1. Historically, a clock pulse of, for example, 1125 Hz is applied from the clock counter 23 to the enable terminal EN.

The enable 977 of the counter 16a outputs a clock pulse 3f of 2 8 1.5 fiz from the clock counter 23 to the child EN.

- The explanation below is based on the basic 9-go operation in which regular pre-+14 information and correct information signals were manually input. During broadcasting, signals of 440117 and 88011z may be present.

These signals must not cause malfunctions.

For this reason, a circuit to prevent the creation of φL1 in each building is installed5.

As explained earlier, 6a is the 440 FI7. If the signal continues for a predetermined period of time, the input is recorded and an instruction is given to the counter 17a to set the pulse width at 1tll.

If so, a reset pulse is output from the rational sum means 23, and the forecast counter 9a and the switching signal generation means 21 can be prevented from becoming re-centered and malfunctioning.

On the other hand, if 4401 (z signal is longer than the normal pulse of forecast No. 18), the output of counter 19a is H1tira logic signal (3, where child Q8 outputs 11 logic) (d Nantes gate 19c). is applied to the OR means 23 as an L logic signal using the logic A.

440147. The frequency of the Hz forecast signal and the regular news signal are discriminated, and the duration and pulse interval are visually measured, and only when all of them meet the standards for a regular time signal is the signal determined as a time signal.440147. There is no possibility of malfunction due to 880 Hz signals and 880 Hz signals.

However, since the frequency is not discriminated by a filter, it is possible to output a time signal detection signal with a small time delay, that is, a time delay at the time when the counter 16a counts up. . For example, in the above embodiment, this delay time is 85 mm'4. A"I'I
