Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a clock device that is installed on a street or the like and notifies the time by operating a puppet device or the like at a fixed time, for example, on the hour.

(Prior art) Conventionally, as shown in Utility Model Application Publication No. 49-51267,
For example, a so-called karakuri clock has been proposed, which informs nearby people of the time by activating a puppet device or automatic musical instrument attached to the hour or half past hour.
They are being installed on the streets.

(Problem that the invention aims to solve) Since this type of mechanical clock is located on the street, the timekeeping operation must be stopped on windy days to prevent malfunctions and dangers. To do this, it is possible to attach an anemometer to the watch and stop the operation when the wind speed exceeds a certain value, but a. I feel relaxed.

b. If the wind becomes strong and the time signal operation is canceled,
I think the people who gather to see this (starting about 10 minutes in advance) are out of order, and if they've been waiting in anticipation for minutes and nothing happens, they'll feel uncomfortable and watch the clock. This will greatly damage the image of the installer.

There were problems such as.

(Means for Solving the Problems) The present invention is characterized in that in order to prevent malfunctions and dangers caused by such winds, the discontinuation of the time signal operation is notified before the scheduled time. To this end, the present invention operates the wind speed sensor a certain period of time before the scheduled time when the time signal operation starts, and when the measured value exceeds the set value, it stops the time signal operation that starts at the specified time, and starts reporting from that time. The system is configured to repeatedly perform a warning operation to stop the time operation until the scheduled time has passed.

(Embodiment) FIG. 1 is a circuit diagram showing an embodiment of the present invention, and FIG. 2 is a time chart showing its operation.

In the figure, a master clock 2 measures the time, and the measured time is displayed on a display section installed in a place that cannot be seen from the street. The time measurement output of the master clock 2 is input to a preceding pulse generation circuit 4, which outputs a pulse signal A with a constant period, for example, a one-minute period, slightly earlier than when the displayed time changes. This pulse signal A is supplied to a large device clock 6 (pointer display type) installed on the street, and drives the pointer in response to the pulse generation. In this case, the time displayed on the device clock 6 changes earlier than the time displayed on the master clock 2, and the time seems to be inconsistent, but since the gear train and hands of the device clock 6 are large, they are not actually driven. It takes a long time to reach the desired position on the scale of the dial. In this embodiment, the pulse signal is generated slightly earlier by the advance pulse output circuit 4 in consideration of the movement time of the pointer. The movement time of this pointer is about 8 seconds in a clock driven at a one-minute cycle, and the preceding pulse generation circuit 4 is configured to keep the time of the second measured by the master clock 2.
It is configured to output pulse signal A upon detecting that 52 seconds have passed.

Further, the time signal measured by the master clock 2 is input to the before-the-hour detector 8. This hourly detector 8
outputs detection signal B from 13 minutes before the hour to before the hour.

In response to this detection signal B, the wind speed sensor 10 starts operating and measures the wind speed. If the wind speed exceeds a certain value while the detection signal B is being generated, the detection signal E is supplied to the first gate circuit 12. The first gate circuit 12 also receives a detection signal B from the hourly detector 8 and a one-minute period pulse signal A that is input via an OR gate 14 and an AND gate 16 which is a third gate circuit. and
The pulse signal A is configured to pass only when both detection signals B and E are generated.

The pulse signal A that has passed through the first gate circuit 12 is input to the set input S of the FF 20 in the alarm device 18. As a result, the Q output signal I of FF20 becomes H.
This signal I is delayed by the delay circuit 22 and supplied to the audio circuit 24. As a result, you will hear a sound that indicates that the time signal operation will be canceled, for example, "Bing pong, (BGM approximately 10 seconds), Ping pong. We apologize for the inconvenience, but the automatic stop device has activated and we will stop the performance. Thank you for your understanding. (BGM approximately 30 seconds)" warning sound is repeated.

Further, the pulse signal F from the first gate circuit 12 activates a three-minute timer 26. By this 3
minute timer 26 generates an output signal G after 3 minutes;
This signal G causes the Q output signal I of the FF 20 to be set to L level, thereby stopping the warning operation. The output signal G is also input to a restart circuit consisting of a delay circuit 28 which delays the signal by about 10 seconds. Therefore, the output signal G is delayed and becomes the output signal H, which is input to the first gate circuit 12 via the OR gate 14. Like the pulse signal A, the first gate circuit 12 allows this output signal H to pass through only while the detection signals B and E are being generated, and outputs it to the set input S of the FF 20.
As a result, the Q output signal I of the FF 20 becomes H level again, and the warning operation is repeated. This operation continues until the hour comes, when the detection signal B from the pre-hour detector 8 disappears and the output signal H no longer passes.

Furthermore, the output signal F from the first gate circuit 12 is also input to the set input S of the FF 32 in the second gate circuit 30. As a result, the output signal K of the FF 32 goes to the L level, and the AND gate 34 is closed, and the detection signal of the hour detector 36, which detects that the time measured by the master clock 2 is on the hour, becomes the time signal. device 38. As a result, once the detection signal E is generated from the wind speed sensor 10 and a warning starts in response to the pulse of the pulse signal A, the hourly time reporting operation is not performed. When the after-hours detector 40 detects that five minutes have passed since the hour, the detection signal is input to the reset input R of the FF 32. As a result, the output signal K of the FF 32 returns to the H level, and the AND gate 34 is opened and the detection signal from the hour detector 40 can be supplied to the time signal device 38.

Further, the output signal K of the FF 32 is input to an AND gate 16, and once a warning is started, the AND gate 16 is closed to prevent the pulse signal A from being supplied to the alarm device 18, thereby preventing malfunction.

In this embodiment, the time reporting operation is performed every hour on the hour, but the present invention can also be applied to a clock that is activated every half hour, and the audio circuit 24 may be a display circuit.

(Effects of the invention) As described above, according to the invention, since a warning is given from the time when onlookers begin to gather until the scheduled time to stop the time signal operation due to the wind becoming stronger, it may be mistaken for a malfunction. It will not make the viewer uncomfortable, and it will not damage the image or credibility of the clock installer. In particular, the configuration of the present invention performs the warning operation in conjunction with the pulse that drives the device clock, so the measurement values up to just before the time alarm operation is used are used. very accurately in those that detect
Moreover, alarms and time-signaling operations can be carried out easily without causing malfunctions.
