As mentioned above, a very special time, for example 2: 3 am
It is also possible to configure to transmit once a day only for 8 minutes.

FIG. 5 is a flowchart for explaining the operation of the time signal relay device 2 according to the present embodiment.

In the time signal relay device 2, in the initial state where the power is turned on, the control signal S24e is not output from the controller 24 to the power controller 25, and no driving power is supplied to the transmission circuit block 23 (S1). ). Then, the first control signal S24a is output from the controller 24 to the switch circuit 214 of the antenna unit 24. Thus, in the antenna unit 21, the fixed terminal a of the switch circuit 24 is connected to the switching terminal b, and a parallel resonance circuit including the resonance coil 211 and the first capacitor 212 is formed (S2).

In this state, the standard time radio signal S1 is received by the parallel resonance circuit formed by the antenna unit 21 (S1).
3) Further, in the receiving circuit 22, the signal is converted into a baseband signal of the standard time radio signal S1 through a receiving RF amplifier, a detecting circuit, a rectifying circuit, and an integrating circuit and input to the controller 24.

The controller 24 receives the baseband signal from the receiving circuit 22 and decodes the JG2AS time code. If the standard time radio signal is normally received, the time data such as hours, minutes, and 00 seconds is transmitted. Gained,
The internal clock is corrected, and the internal clock is incremented (S4). Further, for example, the time is displayed on the display 26 (S5).

Next, it is determined whether or not the internal clock has reached a preset transmission time (for example, 2:38 am) zone (S6). If it is determined in step S6 that the time has not reached the transmission time zone, it is determined whether or not the time has reached a preset reception time (for example, 2:36 am) (S7). If it is determined in step S7 that the time is not in the reception time zone, the process returns to the display process in step S5, and it is determined whether or not the time is in the transmission time zone described above.

If it is determined in step S6 that the transmission time has come, the controller 24 outputs a control signal S24e to the power controller 25. As a result, drive power is supplied from the power controller 25 to the transmission circuit block 23 (S
8). At this time, the second control signal S24b is output from the controller 24 to the switch circuit 214 of the antenna unit 24. Thus, in the antenna unit 21, the fixed terminal a of the switch circuit 24 is connected to the switching terminal c, and a series resonance circuit including the resonance coil 211 and the second capacitor 213 is formed (S9).

In this state, the control signal S24c is output to the oscillator 231 and the control signal S24d is output to the transmission timing circuit 232 from the controller 24. Thus, the time data having substantially the same frequency (40 kHz) as the standard time radio signal and including the time code based on the internal clock can be stored in JG2.
AS baseband signals are generated in the same format,
Through a series resonance circuit formed by the antenna unit 21, J
It is transmitted to the radio-controlled timepiece 3 as a time radio signal S2 having the same format as that of the G2AS (S10).

When the transmission of the time radio signal S2 is completed, the output of the control signal S24e from the controller 24 to the power controller 25 is stopped. Thus, the supply of the driving power from the power controller 25 to the transmission circuit block 23 is stopped (S11). Then, the first control signal S24a from the controller 24 is replaced with the switch circuit 2 of the antenna unit 24 instead of the second control signal S24b.
14 is output. Thereby, in the antenna unit 21,
The fixed terminal a of the switch circuit 24 is connected to the switch terminal b to form a parallel resonance circuit including the resonance coil 211 and the first capacitor 212 (S12).
It returns to the display processing of.

If a negative determination result is obtained in step S6 and a positive determination result is obtained in step S7, it is determined that the set reception time zone has been reached and the processing in step S3 is performed. Returning, the above-described reception processing (S3 to S5) by the parallel resonance circuit, the reception circuit 22, and the controller 24 is performed.

The radio-controlled timepiece 3 outputs a standard time radio signal S1 including a time code of a predetermined frequency (40 kHz) transmitted from the key station 1 by AM modulation or a time radio signal S2 transmitted from the time signal relay device 2. In response, for example, if the reception status of the standard time radio signal S1 or the time radio signal S2 is good, the pointer position is corrected to the time indicated by the time code, and if the reception status is bad, the user receives radio waves. Is not good.

Thus, the operation in the initial correction mode is completed.

After completing the operation in the initial correction mode, the control circuit 34 controls the normal correction mode. In the normal correction mode, the time radio signal receiving system 31 is driven by a power supply (not shown) for one minute before and after the hour, including every hour, so that the standard time radio signal S1 from the key station 1 can be received, for example, every hour.

It is also possible to control so that the receivable time zone of the standard time radio signal S1 from the mobile station and the receivable time zone of the time radio signal S2 from the time signal relay device 2 are different.

In the normal correction mode, the control circuit 34 supplies the standard time radio signal S from the key station 1 in principle.

From the key station 1, a long-time (40 kHz) standard time radio wave (JG2AS) S1 having a format as shown in FIG. 2A is AM-modulated and transmitted. The standard time radio signal S1 transmitted from the key station 1 is transmitted to the transmission / reception antenna 20 of the time signal relay device 2 and the radio-controlled timepiece 3
Is received by the receiving antenna 31a.

In the time signal relay device 2, for example, the control signal S24e is not output from the controller 24 to the power controller 25, and the transmission circuit block 23
Is not supplied with driving power. Then, the first control signal S24a is output from the controller 24 to the switch circuit 214 of the antenna unit 24.
A parallel resonance circuit including the resonance coil 211 and the first capacitor 212 is formed. In this state, the standard time radio signal S1 is received by the parallel resonance circuit formed by the antenna unit 21, and further converted by the receiving circuit 22 into a baseband signal of the standard time radio signal S1 and input to the controller 24.

The controller 24 receives the baseband signal, decodes the JG2AS time code, and outputs the hour, minute,
Time data such as 0 seconds is obtained, the internal clock is corrected, the internal clock is incremented, and the time is displayed on the display 26, for example.

Is stopped. Then, the first control signal S24a is output from the controller 24 to the switch circuit 214 of the antenna unit 24 instead of the second control signal S24b. As a result, the antenna unit 21
Now, the resonance coil 211 and the first capacitor 212
Is formed, and the standard time radio signal S1 can be received until the next transmission time zone.

In the radio-controlled timepiece 3, the control circuit 34 controls the time radio signal receiving system 31 for one minute before and after the hour, including every hour, so that the standard time radio signal S1 from the key station 1 can be received at every hour. Drive power from a power supply (not shown). Thus, the long wave (for example, 40 kHz) including the time code signal from the key station received by the receiving antenna 31a of the time radio signal receiving system 31 is converted into the long wave receiving circuit 31b.
Receives predetermined signal processing, and is output to the control circuit 34 as a pulse signal S31.

The control circuit 34 decodes the received radio signal, and when it is determined that the reception is normal, as a result of the decoding, count control of various counters and first and second counts based on the basic clock by the oscillation circuit 33. 2, the detection signals DT ₁ ,

₂ is output to the stepping motor 210 for the second hand and the stepping motor 410 for the hour and minute hands via the buffer 37 to perform rotation control, thereby performing time correction control. Then, a standard radio wave normal reception flag indicating that the standard time radio wave signal S1 has been normally received is set.

When it is determined that the reception time is not the reception time of the standard time radio signal S1 and that the reception is not normal or the standard radio wave normal reception flag is set, the time radio signal S2 from the time signal relay device 2 is It is determined whether or not it is the reception time. Here, when it is determined that the reception time of the time radio signal S2 is reached, and the standard radio wave normal reception flag is set, the standard radio wave reception system The drive power is not supplied to the power supply 31 from a power supply (not shown), the standard radio wave normal reception flag is reset, and the process shifts to the normal processing.

As described above, according to the present embodiment, the resonance coil 211, the first capacitor 212,
When the second capacitor 213 and the first control signal S24a are input, one end of the resonance coil 211 is connected to the first electrode of the first capacitor 212, and the other end is connected to the second electrode of the first capacitor 212. Connected to form a parallel resonant circuit,
When the second control signal S24b is input, the resonance coil 211

A transmission which is connected to the second electrode of the capacitor 213 and generates and outputs a time radio signal having the same frequency as the standard time radio signal at a predetermined transmission time and including a time code based on the internal clock. In block 23, the first control signal S24a is output to the antenna section 21 during the reception time zone, and the second control signal S24b is output to the antenna section during the transmission time zone, and is received by the parallel resonance circuit of the antenna section 21. And a controller 24 for inputting the set standard time radio signal and correcting the internal clock at a time corresponding to the time code included in the received radio signal, so that the transmission including the reception antenna unit including the parallel resonance circuit and the series resonance circuit is provided. There is no need to provide an antenna unit, and there is an advantage that the apparatus can be prevented from being increased in size and cost.

In the present embodiment, the transmission circuit block 23 supplies the driving power to the transmission circuit block 23 only in the transmission time period, and stops the supply of the driving power to the transmission circuit block 23 in the reception time period. Since the controller 25 is provided, the transmission circuit block 23 can be prevented from becoming a noise source at the time of reception, and deterioration of the reception sensitivity of the standard time radio wave can be prevented.

Further, according to the present embodiment, the time signal relay device 2 is configured to transmit once a day only at a very special time, for example, at 2:38 am. When the standard time radio signal S1 is received, control is performed so that the receivable time zone of the standard time radio signal S1 from the key station 1 and the receivable time zone of the radio signal S2 from the time signal relay device 2 are different. Therefore, the radio signal S2 from the time signal relay device 2 can be suppressed to a minimum as an interfering radio wave, and the radio-controlled timepiece 3 can be accurately and reliably provided.
Can be adjusted.

The control circuit 34 determines whether or not time can be set even in the normal correction mode. If the time can be set, the control circuit 34 corrects the pointer position. If not, the control circuit 34 turns on the light emitting element 36 to that effect. Since the notification is performed, the radio wave reception state can be recognized at any time during operation.

In this embodiment, the transmission time of the time code radio signal S2 of the time signal repeater 2 is set to 2:38 am
Although the present invention has been described as being fixedly performed, the present invention is not limited to this, and may be configured to be changed according to the situation. In this case, the initially set time zone of 2:38 am of the transmission time of the time signal relay device 2 is large in extraneous noise depending on the installation location of the radio-controlled timepiece 3 and is suitable as the reception time of the time signal relay device 2. Even when the time is not set, the time can be reset to a time suitable for arbitrary reception, so that there is an advantage that the time signal can be relayed more reliably and the time of the radio-controlled timepiece can be accurately and reliably corrected.

In the present embodiment, the switch circuit 214 of the antenna unit 21 is illustrated and described as having a mechanical switching contact. For example, as shown in FIG. First capacitor 2
A field-effect transistor, for example, an n-channel first MOS transistor NT1 is connected between the first electrode 12 and the twelve first electrodes, and between the second electrode of the second capacitor 213 and the output terminal of the transmission circuit block 23. The second M of n channels
It is also possible to configure to connect the OS transistor NT2. In this case, the first MOS transistor N
The first control signal S24a is supplied to the gate electrode of T1, and the second control signal S24b is supplied to the gate electrode of the second MOS transistor NT2. When the parallel resonance circuit is formed, the first control signal S24a is supplied at a high level and the second control signal S24b is supplied at a low level, the first MOS transistor NT1 is turned on, and the second control signal S24b is turned on. MOS transistor NT2 is kept off. On the other hand, when a series resonance circuit is formed, the first control signal S24a is supplied at a low level, the second control signal S24b is supplied at a high level, the first MOS transistor NT1 is turned off, and the second control signal S24a is turned off. MOS transistor NT2 is kept conductive.

Here, an example in which an n-channel MOS transistor is used has been described. However, a p-channel MOS transistor can be applied to at least one of the first and second transistors. When a p-channel MOS transistor is used, the level of a control signal to be supplied is opposite to that of an n-channel MOS transistor. That is, the p-channel MOS transistor is supplied at a low level when it is kept in a conductive state, and at a high level when it is kept in a non-conductive state.

As described above, by using the field effect transistor as the switching element, the life of the switch circuit can be extended.

Further, in the present embodiment, the case where a parallel resonance circuit or a series resonance circuit is formed by using two capacitors has been described as an example. However, as shown in FIG. A switch SW1 is connected between one end of the capacitor 211 and the first electrode of the capacitor 215, and a switch SW1 is connected between the other end and the second electrode of the capacitor 215.
W2, a switch SW3 is provided between a connection point between the first electrode of the capacitor 215 and the switch SW1 and an input terminal of the receiving circuit 22, and a connection point between the second electrode of the capacitor 215 and the switch SW2. Transmission circuit block 23
It is also possible to provide a switch SW4 between the output terminal and the output terminal.

In such a configuration, when a parallel resonance circuit is formed at the time of reception, the switches SW1, SW2, and SW3 are kept conductive by the first control signal S24a. On the other hand, when a series resonance circuit is formed at the time of transmission, the switches SW1 and SW4 are kept conductive by the second control signal S24b. Note that the switch SW
Of course, 1 to SW4 can be constituted by switching elements such as field effect transistors.

In such a configuration, similarly to the above, it is not necessary to provide a receiving antenna unit including a parallel resonance circuit and a transmission antenna unit including a series resonance circuit, thereby increasing the size and cost of the device. Can be prevented.

[0093]

As described above, according to the present invention,
There is an advantage that it is possible to prevent an increase in the size and cost of the device.

Further, since the power supply control circuit for supplying power to the transmission system circuit only at the time of transmission is provided, the transmission system circuit can be prevented from becoming a noise source at the time of reception, and the reception sensitivity of the standard time radio wave is degraded. There is an advantage that can be prevented.
