Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic timepiece and a method of controlling the electronic timepiece, and more particularly to an electronic timepiece displaying the remaining energy of a power supply and a method of controlling the electronic timepiece.

[0002]

2. Description of the Related Art In recent years, a wristwatch-type electronic timepiece has built-in power supply means. This power supply means includes a power generator having a rotating weight and a power storage means (large-capacity capacitor) for storing electric energy generated from the power generator. This is roughly configured. In this type of electronic timepiece, the time is displayed by a time display unit using electric energy discharged from a capacitor, and the operation of the timepiece is performed for a long time without replacing a battery. .

[0003]

An electronic timepiece incorporating a power supply means having a power generator as described above supplies a stable electric energy for a long period of time. Or, when the non-carrying state is continued, or when the mode is forcibly switched by the user, these states are detected, and the mode of the electronic timepiece is changed from the driving mode (display mode) for displaying the time. The mode was switched to the power saving mode in which the time was not displayed. For example, in an analog timepiece, the driving of the hands is stopped.

In this power saving mode, although the time is not displayed, electric energy is supplied to a part of the drive control circuit in order to count the current time. For this reason, the electric energy is consumed even in the power saving mode, and the user cannot know the remaining amount of the electric energy in the power supply means in the power saving mode, and grasps a period during which the state of the power saving mode can be maintained. There is a problem that you can not.

Further, when the power saving mode is executed for a long time and the electric energy stored in the power storage means of the power supply means is reduced, the operation mode of the time display unit is changed from the power saving mode to the power saving mode. When the mode is switched to the display mode, it takes time to store electric energy required for driving the time display unit in the power supply means, and the time display unit may not be driven immediately. In such a case, the user may think that the electronic timepiece is out of order.

Furthermore, in the electronic timepiece according to the prior art, the user could not arbitrarily check the amount of electric energy of the power supply means.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an electronic timepiece capable of displaying the amount of electric energy of a power supply means and a method of controlling the electronic timepiece.

The stepping motor 10 is driven by a pulse signal. In recent years, small and lightweight stepping motors of this type have been widely adopted as actuators for small electronic watches or information devices suitable for carrying.

<1.2.2.4.2. Hour / Minute Hand Movement Mechanism Next, the hour / minute hand movement mechanism CHM will be described. The stepping motor 60 used in the hour and minute hand movement mechanism CHM is:
The configuration is almost the same as that of the stepping motor 10.

The stepping motor 60 of this embodiment is
A drive coil 61 for generating a magnetic force by a drive pulse supplied from the hour and minute drive circuit 30HM;
And a stator 62 excited by the
2 has a rotor 63 rotated by a magnetic field excited inside. The rotor 63 is of a PM type (permanent magnet rotating type) having a disk-shaped two-pole permanent magnet. Further, different magnetic poles due to the magnetic force generated by the drive coil 61 are provided on the stator 62.

A calendar correction train (for example, a first calendar correction transmission wheel, a second calendar correction transmission wheel, a calendar correction wheel, a date wheel, etc.) may be additionally provided.

[1 ・ 2 ・ 5] Second hand drive circuit and hour / minute hand drive circuit Next, the second hand drive circuit 30S and the hour / minute hand drive circuit 30HM will be described. Here, since the second hand drive circuit 30S and the hour / minute hand drive circuit 30HM have the same configuration, only the second hand drive circuit 30S will be described with reference to FIG.

Here, the second hand drive circuit 30S supplies various drive pulses to the stepping motor 10 under the control of the control circuit 23. The second hand drive circuit 30S
Is a P-channel transistor 3 connected in series
3a, N-channel type transistor 32a, and P
The second hand driving circuit 30S includes a bridge circuit constituted by a channel type transistor 33b and an N channel type transistor 32b.
A rotation detecting resistors 35a and 35b are connected in parallel with a and 33b, respectively, and sampling P-channel transistors 34a and 34b for supplying chopper pulses to the resistors 35a and 35b are provided.

As a result, the second hand drive circuit 30S includes these transistors 32a, 32b, 33a, 33b, 3
By applying control pulses having different polarities and pulse widths from the control circuit 23 to the respective gate electrodes 4a and 34b at respective timings, drive pulses having different polarities are supplied to the drive coil 11 or rotation of the rotor 13 is detected. And a detection pulse that excites an induced voltage for detection of a magnetic field and a magnetic field.

[1.2.6] Control Circuit Next, the configuration of the control circuit 23 will be described with reference to FIG. 2. The functional block diagram of FIG.
And its peripheral configuration.

Here, the control circuit 23 includes a pulse synthesizing circuit 22, a mode setting section 90, a drive control circuit 24, and the like. First, the pulse synthesizing circuit 22 uses an oscillation circuit that oscillates a reference pulse having a stable frequency using the reference oscillation source 21 such as a quartz oscillator, and a divided pulse obtained by dividing the reference pulse and the reference pulse. A synthesizing circuit for synthesizing and generating pulse signals having different pulse widths and timings.

Next, the mode setting section 90 includes a power generation state detection section 91, a set value switching section 95 for switching a set value used for detecting the power generation state, and a charging voltage Vc (step-up / down circuit) of the large-capacity capacitor 48. A voltage detection circuit 92 for detecting the post-step-up / step-down voltage VSS from the power supply 49; a central control circuit 93 for controlling the time display mode according to the power generation state and for controlling the boost ratio based on the charging voltage; And a mode storage unit 94.

The power generation state detection unit 91 is provided with the power generation device 40
The first detection circuit 9 that determines whether or not the power generation state is established by comparing the electromotive voltage Vgen of the first embodiment with the set voltage value V0.
7 and the time when the power generator 40 is in the power generation state by the first detection circuit 97 is defined as the power generation continuation time Tgen, and the time Tgen is compared with the set time value T0 to determine the stable power generation state. And two detection circuits 98.

Then, the power generation state detection section 91 determines that the power generation section A is in the power generation state when both the conditions of the first detection circuit 97 and the second detection circuit 98 are satisfied. . Here, the set voltage value V0 is Vdd (= GN
This is a negative voltage based on D), and indicates a potential difference from Vdd.

Here, the set voltage value V0 used in the first detection circuit 97 is controlled by the set value switching section 95, and the set value switching section 95 switches from the display mode to the power saving mode. Then, the value of the set voltage value V0 used for the first detection circuit 97 is changed. That is, in this example,
When the display mode is set, the set voltage value is Va, and when the power save mode is set, the set voltage value is Vb.
Set to b. Therefore, large power generation is required to switch from the power saving mode to the display mode. Note that the set value switching unit 95 may switch the set time value T0 used for the second detection circuit 98.

The central control circuit 93 includes a detection circuit 9
7, a non-power generation time measuring circuit 99 for measuring a non-power generation time Tn during which no power generation is detected.

On the other hand, when returning from the power saving mode to the display mode, the power generation state detection unit 91 detects that the power generation unit A is in the power generation state, and displays the charging voltage Vc of the large capacity capacitor 48 from the power saving mode. This is executed when the condition that sufficient electric energy remains to return to the mode is satisfied.

In this case, in the power saving mode, the limiter circuit LM operates, and when the limiter circuit LM is turned on (closed), the power generation unit A is short-circuited. Even in the state, it cannot be detected, and it is not possible to shift from the power saving mode to the display mode. Therefore, in the present embodiment, in the power saving mode, the limiter circuit LM is turned off (open) regardless of the power generation state of the power generation unit A, and the power generation state detection unit 91 determines the power generation state of the power generation unit A. Can be reliably detected.

Further, since the power supply section B of this embodiment is provided with the step-up / step-down circuit 49, as described above, even if the charging voltage Vc is somewhat low, the step-up / step-down circuit increases the charge voltage Vc by the step-up / step-down circuit 49. The post-voltage Vss makes it possible to drive the hand movement mechanisms CS and CHM. On the other hand, even when the charging voltage Vc is somewhat high and higher than the driving voltage of the hand movement mechanisms CS and CHM, the hand movement mechanisms CS and CHM are driven by the post-boost voltage Vss obtained by lowering the charging voltage Vc by the step-up / down circuit 49. It is possible to Further, the central control circuit 93 determines the step-up / step-down ratio based on the charging voltage Vc detected by the voltage detecting circuit 92 and controls the step-up / step-down circuit 49.

However, if the charging voltage Vc is too low,
Even if the pressure is increased, a voltage that can operate the hand movement mechanisms CS and CHM cannot be obtained. In such a case, when the mode is shifted from the power saving mode to the display mode, accurate time display cannot be performed, and wasteful power is consumed. Therefore, by comparing the charging voltage Vc with a predetermined set voltage value Vb, it is determined whether or not the charging voltage Vc is sufficiently charged, and this is determined as a condition for shifting from the power saving mode to the display mode. Good.

The operation mode set in this way is stored in the mode storage unit 94, and the information is stored in the drive control circuit 2
4. It is supplied to the time information storage section 96 and the set value switching section 95.

Here, the drive control circuit 24 switches the operation mode of the electronic timepiece 1 from the display mode to the power saving mode by operating the external input device 100, for example.
The supply of the control signal to the second hand drive circuit 30S and the hour / minute hand drive circuit 30HM is stopped, and the operations of the second hand drive circuit 30S and the hour / minute hand drive circuit 30HM are stopped. As a result, the motors 10 and 60 do not rotate, and stop displaying the time.

Next, the drive control circuit 24 generates a drive pulse according to the mode based on various pulses output from the pulse synthesis circuit 22. First, in the power saving mode, the supply of the driving pulse is stopped. Further, the drive control circuit 24 has a current time return function of returning the re-displayed time display to the current time immediately after switching from the power saving mode to the display mode. That is, by supplying a fast-forward pulse having a short pulse interval as a drive pulse to the second hand drive circuit 30S and the hour / minute hand drive circuit 30HM, the hand movement is advanced to quickly return to the current time.

Next, after the supply of the fast-forward pulse is completed, a drive pulse having a normal pulse interval is applied to the second hand drive circuit 30.
Supply to S and hour and minute hand drive circuit 30HM.

On the other hand, reference numeral 101 denotes a second counter circuit. The second counter circuit 101 is operated by a second position counter 102, a time counter 103, and a coincidence detecting circuit 104 connected to the outputs of the counters 102 and 103 for 60 seconds. It is configured as a counter.

Here, a pulse signal interlocked with the second hand drive signal is input to the second position counter 102, and when the display mode is forcibly shifted from the display mode to the power saving mode by operation of the external operation device 100, for example, the drive control circuit 24 Outputs a fast-forward pulse corresponding to the charging voltage Vc of the large-capacity capacitor 48, rotates the second hand 55 via the second motor 10, and displays the remaining energy by the second hand 55. Then, when the output of the drive signal stops, the second hand stops and enters the power saving mode. In addition, since the second hand drive signal is not input during the power saving mode, the second position counter 102 does not count up, only the time counter 103 counts up. (Faster than 1 Hz) is input, and the second position counter 102 is counted up until it reaches the same value as the value of the time counter 103. When the value of the second position counter 102 becomes equal to the value of the time counter 103, the coincidence detection circuit 104 stops fast-forwarding and shifts to a normal display mode.

Reference numeral 111 denotes an hour / minute counter circuit. The hour / minute counter circuit 111 has an hour / minute position counter 112 and a time counter 113 similarly to the second counter circuit 101.
When the minute hand 76 moves one minute, the coincidence detecting circuit 114 connected to the output side of the counters 112 and 113 constitutes a 1440 (24 × 60) counter. When the minute hand 76 moves in 20 seconds, 3 minutes per minute
Since the count is performed twice, the count becomes 4320 (24 × 60 × 3).

[1.2.7] Voltage Detector Next, the voltage detector 9 will be described with reference to FIGS.
2 will be described.

<1.2.7.1> Configuration of Voltage Detection Circuit First, the configuration of the voltage detection circuit 92 will be described with reference to FIG. The voltage detection circuit 92 divides the charging voltage Vc of the large-capacity capacitor 48 to generate a detection voltage Vc ′ proportional to the charging voltage Vc, a reference power supply 92B that generates a reference voltage Vref, and a detection voltage Vc 'and reference voltage Vr
ef and a comparator 92C that outputs an original limiter signal SLIM0 and a latch circuit 92D that latches and holds the original limiter signal SLIM0 at a timing corresponding to the sampling signal SS3 and outputs the same as a limiter signal SLIM1.
A switch SW1 for supplying power to the reference power supply 92B based on the sampling signal SS1,
And a switch S2 for connecting the voltage dividing circuit 92A to the large-capacity capacitor 48 based on the sampling signal SS3.
W3.

In this case, the sampling signal SS
1, sampling signal SS2 and sampling signal SS3
Is from the "H" level to the "L" level, that is, the timing at which the switches SW1, SW2, and SW3 are turned on is in the order of the sampling signal SS1, the sampling signal SS2, and the sampling signal SS3.

Therefore, power is supplied to the reference power supply 92B which takes a long time to become most stable, and then power is supplied to the comparator 92C. After the operation of the reference voltage Vref and the operation of the comparator 92C are stabilized, the voltage dividing circuit 92A
Is connected, and the original limiter signal SLIM0 is taken in by the latch circuit 92D.

On the other hand, the voltage dividing circuit 92A comprises resistors 92A1, 92A2, 92A3, 9 having a resistance value R connected in series.
2A4, an N-channel transistor 92A5 connected to both ends of the resistor 92A3, and an N-channel transistor 92A6 connected to both ends of the resistor 92A4.

In the voltage dividing circuit 92A, the resistor 9
Since 2A1 to 92A4 are voltage dividing resistors, the detection voltage Vc 'obtained by reducing the charging voltage Vc to 1/4 is taken out by the resistor 92A1. When the charge amount of the charging voltage Vc decreases, the transistors 92A5 and 92A6 are appropriately closed to detect the detection voltage Vc extracted by the resistor 92A1.
Is 1/3, 1/2 of the charging voltage Vc. As a result, the state of charge of the large-capacity capacitor 48 is changed to a full charge,
Displayed as / 4 charge and 1/2 charge. By appropriately selecting the number and resistance value of the voltage dividing resistors, signals for various remaining amount display modes are obtained.

<1.2.7.2> Operation of Voltage Detection Circuit Next, the operation will be described with reference to the processing flowchart of FIG. 10 and the timing chart of FIG. Although the transition timing is actually shifted in the order of the sampling signal SS1, the sampling signal SS2, and the sampling signal SS3, in FIG. 11, the transition timing of the sampling signals SS1, SS2, and SS3 is simplified for the sake of simplicity. Are almost the same timing.

First, it is determined whether or not the elapsed time T from the previous sampling timing is equal to or longer than the sampling period Tsp (step S1).

If it is determined in step S1 that the elapsed time T from the previous sampling timing is shorter than the sampling period Tsp (step S1; No), the process enters a standby state, and the process in step S1 is repeated.

If it is determined in step S1 that the elapsed time T from the previous sampling timing is equal to or longer than the sampling period Tsp (step S1: Yes), FIG.
As shown at times t1, t3, and t4, the sampling signal SS1, the sampling signal SS2, and the sampling signal SS3 sequentially transition from the "H" level to the "L" level, that is, the switches SW1, SW2, and SW3 are switched. Power is sequentially supplied to the reference power supply 92B, and then power is supplied to the comparator 92C. After the operation of the reference voltage Vref and the operation of the comparator 92C are stabilized, the voltage dividing circuit 92A is connected, and the detection voltage Vc 'is reduced. The comparator 92C determines whether or not the voltage exceeds the reference voltage Vref (step S2).

In the determination in step S2, as shown from time t2 to time t5 in FIG. 11, when the detection voltage Vc 'exceeds the reference voltage Vref and the original limiter signal SLIM0 has transitioned to the "H" level. Is (Step S2; Yes),
As shown at times t3 and t4 in FIG.
, The "H" level original limiter signal SLIM0 is fetched,
The limiter signal SLIM1 becomes “H” level (step S
3).

On the other hand, in the determination of step S2, FIG.
As shown from time t1 to time t2 or time t5 of No. 1, when the detection voltage Vc 'is lower than the reference voltage Vref and the original limiter signal SLIM0 has transitioned to the "L" level (step S2; No). As shown at times t1 and t6 in FIG. 11, the original limiter signal SLIM0 of "L" level is fetched into the latch circuit 92D, and the limiter signal SLIM1 =
The level becomes the “L” level (step S4), and the process returns to step S1. Thereafter, the same process is repeated.

As described above, by intermittently performing the operation of the voltage detection circuit 92 based on the sampling signal, the power consumption for the detection can be further reduced.

[1.2.8] Magnification setting operation by central control circuit <1.2.8.1> Relationship between charging voltage and magnification of buck-boost circuit First, referring to FIG. The relationship between the charging voltage Vc and the magnification of the step-up / step-down circuit 49 will be described. For convenience of explanation, it is assumed that in the initial state, the power generation state detection circuit 91 is in the operating state, the limiter circuit LM is in the non-operation state, and the step-up / step-down circuit 49 is in the non-operation state. In this initial state, the large-capacity capacitor 48
Is, for example, less than 0.45 [V],
The minimum voltage for driving the hand movement mechanisms CS and CHM is 1.2
It is set to less than [V].

(1) The charging voltage Vc is 0.0 to 0.62
[V] (range of × 3) The charging voltage Vc of the large-capacity capacitor 48 is 0.45 [V]
If less than, the step-up / step-down circuit 49 is in an inactive state,
The charging voltage Vc detected by the voltage detection circuit 92 is also 0.45.
Since it is less than [V], the hand movement mechanisms CS and CHM remain in the non-driving state. When the charging voltage Vc of the large capacity capacitor 48 exceeds 0.45 [V], the central control circuit 9
A command signal for causing the step-up / step-down circuit 49 to perform triple boosting is output from 3. Thus, the step-up / step-down circuit 49 performs a triple boosting operation.
The operation is continued until the voltage reaches 62 [V]. As a result, the voltage Vss after step-up / step-down becomes 1.35 [V] or more, and the hand movement mechanism C
s and CHM are driven.

In this case, depending on the power generation state, for example, when the electronic timepiece 1 is rapidly shaken, the voltage may suddenly increase and exceed the rated voltage.
If the step-up / step-down ratio is controlled according to the power generation state, such as double or 1.5-fold boosting, without shifting to the triple boosting operation, more stable supply of the operating voltage is possible. The same applies to the following cases.

(2) The charging voltage Vc is 0.62 [V]-
When the voltage is 0.83 [V] (range of × 2), the charging voltage Vc of the large-capacity capacitor 48 is 0.62 [V].
Is exceeded, the central control circuit 93 sends a 2
A command signal for performing double boosting is output. As a result, the step-up / step-down circuit 49 performs a double boosting operation, and this double boosting is continued until the charging voltage Vc becomes 0.83 [V]. As a result, the step-up / step-down voltage Vss is 1.24.
[V] or more, the hand movement mechanisms CS and CHM remain unchanged,
The driving state will be maintained.

(3) 0.83 [V] to 1.23 [V]
(In the range of × 1.5) The charging voltage Vc of the large-capacity capacitor 48 is 0.83 [V]
Is exceeded, the central control circuit 93 outputs a command signal for causing the step-up / step-down circuit 49 to perform 1.5-fold step-up.
Thus, the step-up / step-down circuit 49 performs a 1.5-fold boosting operation.
It is continued until it becomes [V]. As a result, the step-up / step-down voltage Vss becomes 1.24 [V] or more, and the hand movement mechanisms CS, CH
M will still maintain the driving state.

(4) 1.23 [V] or more (range of × 1)
When the charging voltage Vc of the large-capacity capacitor 48 is 1.23 [V]
Is exceeded, the central control circuit 93 sends a 1
A command signal for performing double boosting (short mode), that is, non-boosting operation is output. Thus, the step-up / step-down circuit 49 performs a one-time boosting operation, and this one-time boosting is continued until the charging voltage Vc becomes less than 1.23 [V]. As a result, the voltage Vss after buck-boost becomes 1.24 [V] or more,
The hand movement mechanisms CS and CHM remain in the driven state as usual. Further, when the charging voltage Vc of the large capacity capacitor 48 exceeds 2.5 [V], the limiter circuit L
M is turned on.

In the characteristic diagram of FIG. 12, the charging voltage V
The range of magnifications x3, x2, x1 when c rises and falls.
5, x1 is different. As described above, in the present embodiment, since the magnification of the step-up / step-down circuit 49 is set in the central control circuit 93 by the charging voltage Vc detected by the voltage detection circuit 92, the voltage detection circuit 92 can also be used. The configuration can be simplified.

In addition, the remaining amount display mode, which will be described later, can also be set by a command signal for controlling the step-up / step-down circuit 49. In the case of a 2/3 charge state and a 1.5-fold boost, the state can be set to a 1/2 state.

[1.2.9] Specific Example of Remaining Amount Display FIG. 13 illustrates the remaining amount display mode of the charging voltage Vc of the large-capacity capacitor 48. In the present embodiment, the dial 8
0 and a second hand 55 rotatably arranged on the dial 80 using the stepping motor 10 (the minute hand 76 and the hour hand 77 are not shown).
