Description

  The present invention relates to an electronic timepiece, a reception operation control method, and a program.

  2. Description of the Related Art Conventionally, there are electronic timepieces that can receive radio waves from positioning satellites to acquire accurate date and time information or a current position. In this electronic timepiece, the date and time information can be periodically acquired from the outside to maintain accurate date and time counting. Also, based on the user's input operation, the date and time can be acquired at a desired timing, and the local time settings such as the current position and the time zone and daylight saving time enforcement rules corresponding to the current position can be acquired and updated.

  However, electronic portable watches, in particular, small portable watches such as wristwatches, are limited in the number of configurations related to the reception of operations and the details of possible operations, and when trying to perform many functions based on user operations. There is a problem that the operation content tends to be complicated. On the other hand, it is possible to switch between performing the operation of acquiring only the date / time information when receiving the radio wave from the positioning satellite according to the duration of the predetermined operation or performing the operation of acquiring the date / time information and the position information together. An electronic timepiece that can be used is disclosed (Patent Document 1).

JP 2013-50341 A

  However, it takes a longer time to obtain the positioning result than to acquire the date / time information. Also, in a portable electronic timepiece or the like, the user may be forced to maintain the reception environment during that time, or on the contrary, the reception environment may change greatly with the movement of the user and the positioning may fail or may be further prolonged. During this time, simply waiting for the user to obtain an information acquisition result related to radio wave reception is not convenient for the user.

  An object of the present invention is to provide an electronic timepiece, a reception operation control method, and a program capable of improving user convenience related to information acquisition by radio wave reception.

The electronic timepiece is characterized in that, when the duration time is equal to or longer than a second reference time longer than the first reference time, an operation related to acquisition of current position information is performed after acquisition of date / time information.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a functional configuration of the electronic timepiece 1 of the present embodiment.

  The microcomputer 40 controls various operations of the electronic timepiece 1. The microcomputer 40 includes a host control unit 41, an oscillation circuit 44, a frequency dividing circuit 45, a time measuring circuit 46, and the like.

  The host control unit 41 includes a host CPU 411, a RAM 412, and the like, performs various arithmetic processes and data storage, and controls the operation of the electronic timepiece 1 by the microcomputer 40. The host CPU 411 is a processor that performs arithmetic processing. The RAM 412 is a volatile memory that provides a working memory space to the host CPU 411 and stores temporary data. The RAM 412 may include a non-volatile memory that can be rewritten and updated.

  The oscillation circuit 44 generates a predetermined frequency signal and outputs it to the frequency dividing circuit 45. The oscillation circuit 44 includes a crystal oscillator, for example, and generates a signal of about 16 kHz or about 32 kHz. The crystal oscillator may be externally attached to the microcomputer 40.

  The frequency dividing circuit 45 divides the predetermined frequency signal input from the oscillation circuit 44, converts it to frequency signals used by the host CPU 411, the time measuring circuit 46, and the like, and outputs them to the host CPU 411, the time measuring circuit 46, and the like.

  The time counting circuit 46 counts and holds the current date and time (time) by counting the signal input from the frequency dividing circuit 45. There are some errors in the date and time counted by the clock circuit 46, for example, about ± 0.5 seconds per day. The date and time counted by the timer circuit 46 can be corrected according to a command from the host CPU 411.

  The satellite radio wave reception processing unit 50 includes a reception unit 51, a module control unit 52, a storage unit 53, and the like, and performs a predetermined processing operation for acquiring date / time information (time information) and position information. The receiving unit 51 captures and receives radio waves from the positioning satellite and demodulates the navigation message. The module control unit 52 acquires date and time information, position information of each positioning satellite, and the like based on a navigation message obtained from radio waves from the positioning satellites captured by the receiving unit 51. The module control unit 52 includes a CPU, a RAM, and the like, and performs positioning by calculating the current position of the own device using the acquired date / time information and position information of each positioning satellite. The storage unit 53 stores and holds various setting data related to the reception operation, a control program related to the operation of the module control unit 52, and the like. The positioning satellite to be received is, for example, a positioning satellite related to GPS in the United States, but may be able to receive radio waves from other positioning satellites such as this complementary satellite (such as Michibiki) or GLONASS in Russia.

  The power (consumption current, load) required for the operation related to positioning by the satellite radio wave reception processing unit 50 and the power consumption per time until the positioning operation is completed are the electronic time count operation and display operation by the display unit 62. Compared with other operations in the timepiece 1, it is remarkably large.

  The ROM 64 stores setting data and programs 641 related to various operations of the electronic timepiece 1. The program 641 includes a reception operation control program for controlling the operation of the satellite radio wave reception processing unit 50 in accordance with the operation content received by the operation reception unit 61. The ROM 64 includes a non-rewritable memory such as a mask ROM, an updatable non-volatile memory such as a flash memory, or both.

  The operation accepting unit 61 accepts an input operation from the outside (user) and outputs it as an input signal to the host CPU 411. The operation reception unit 61 includes one or a plurality of push button switches 611 as a configuration for receiving an input operation from the outside. Moreover, the operation reception part 61 may have a crown, a touch panel, etc.

  The display unit 62 displays various information according to the control of the host CPU 411. The display unit 62 can display at least the current time based on the date and time counted by the timing circuit 46. As the display unit 62, for example, a plurality of hands (hour hand, minute hand, second hand, etc.) may be provided, or a configuration capable of digital display using a liquid crystal screen or the like may be provided.

  The notification operation unit 63 performs a predetermined notification operation based on the control of the host CPU 411. Examples of the notification operation unit 63 include a beep sound generation unit that generates a beep sound, a light emission unit that performs a light emission operation, and a combination thereof.

  The power supply unit 70 supplies power from the battery 71 to each unit such as the microcomputer 40 and the satellite radio wave reception processing unit 50. The battery 71 may include a power generation unit included in the electronic timepiece 1 and a secondary battery charged by the generated electromotive force of the power generation unit, or a button type that can be attached to and detached from the electronic timepiece 1 by the user. A battery may be used. Examples of the power generation unit include a solar power generation unit. Here, in order to reduce the weight and size of the electronic timepiece 1, it is desirable to use a light and small battery 71.

Next, a radio wave reception operation from a positioning satellite, which is a reception operation control method in the electronic timepiece 1 of the present embodiment, will be described.
In the electronic timepiece 1, the second reference time (the duration of the pressed state (predetermined input operation) of the predetermined push button switch 611 is longer than the first reference time (for example, 1.5 seconds) and longer than the first reference time ( For example, the date / time is acquired when the time is less than 3.0 seconds), and the current position information is acquired when the predetermined pressing time of the push button switch 611 is 3.0 seconds or longer. The current position information here is not limited to information indicating the current position coordinates, but includes information for identifying a time zone to which the current position belongs and a setting area for daylight saving time enforcement rules.
Of these components, the host control unit 41 and the module control unit 52 constitute a control unit in the electronic timepiece 1 of the present embodiment.

Next, an information acquisition operation by radio wave reception in the electronic timepiece 1 of the present embodiment will be described.
FIG. 2 is a diagram for explaining acquisition switching of date and time information and current position information in the electronic timepiece 1.

  In the electronic timepiece 1, when a predetermined push button switch 611 is kept pressed for a first reference time, for example, 1.5 seconds, the date and time acquisition operation is performed regardless of the release of the pressed state or the final duration. Start. Then, as shown in FIG. 2A, when the pressed state ends in a second reference time longer than the first reference time, for example, less than 3.0 seconds, the reception operation is ended as soon as the date and time are acquired. . On the other hand, as shown in FIG. 2B, when the pressed state continues for the second reference time or longer, the positioning operation is performed using the date and time after acquisition of the date and time. Then, the current position information corresponding to the positioning result is acquired, and the receiving operation is terminated.

  Usually, in order to acquire information from a positioning satellite, activation and initial setting of the receiving unit 51, capture of a transmission radio wave from the positioning satellite, and reception of a signal including information necessary for the captured radio wave are required. When acquiring date and time information, these operations usually require 1.5 seconds or more, but acquisition of date and time information is completed and the pressed state is continued before the second reference time elapses In such a case, the operation of the receiving unit 51 may be stopped once.

  On the other hand, the positioning operation (current position calculation) includes the current accurate date and time, and three or more positioning satellites at the date and time (when altitude information is not required) or four (when including altitude information). And positional information (pseudo distance) of radio wave reception timing from these positioning satellites are required. In the computer, the current position is usually calculated by numerically converging from a predetermined initial position. If the current date and time and the initial position at this time are inaccurate, it may take time until calculation (convergence) or may not converge properly. When performing positioning operations (calculations) multiple times in succession, the results of the previous positioning and date and time acquisition can be used, so the accuracy gradually improves after the second time, but intermittent reception and calculation are performed once. In some cases, the date and time and the initial position (in particular, the current position of the positioning satellite) are slightly deviated from the accurate position every time, so the accuracy is not improved. Therefore, in the electronic timepiece 1, only the date / time information is acquired first, and the positioning calculation based on the date / time is performed, so that the current time position can be reliably and quickly converged even with one positioning.

  In addition, when acquiring current position information, it is possible to acquire a more accurate date and time that accurately considers the distance from the positioning satellite to the current position, but the date and time are not acquired until the current position is acquired. Moreover, since it takes about 18 to 30 seconds to acquire the position information of the positioning satellite, it takes time to correct the date and time. In the electronic timepiece 1, even when positioning is performed, only the date and time is acquired first, so that the date and time are corrected once in a short time, and the corrected date and time are displayed.

FIG. 3 is a flowchart showing a control procedure by the host control unit 41 of the reception operation control process executed by the electronic timepiece 1 of this embodiment.
The reception operation control process is started at a timing when the predetermined duration of pressing the push button switch 611 becomes the first reference time.

  When the reception operation control process is started, the host control unit 41 (host CPU 411) activates the satellite radio wave reception processing unit 50 to perform initial setting (step S101). The host control unit 41 outputs a date / time information acquisition command (an operation execution command related to acquisition of date / time information) to the activated satellite radio wave reception processing unit 50 (step S102). When the satellite radio wave reception processing unit 50 is activated and can be transmitted at the same time as the initial setting, the processes in steps S101 and S102 may be performed simultaneously.

  The host control unit 41 waits for an input from the satellite radio wave reception processing unit 50 after detecting the release of the predetermined push button switch 611 and acquires the input date / time information. Based on the acquired date / time information, the host control unit 41 performs processing such as correction of the date / time counted by the timing circuit 46 and display of the corrected date / time (step S103).

  The host control unit 41 determines whether or not the pressing duration of the predetermined push button switch 611 is equal to or longer than the second reference time (3.0 seconds) (step S104). Note that if date information can be acquired, corrected, and displayed before the detection of the release of the pressed state of the predetermined push button switch 611, the process of step S103 may be performed before the detection of the release of the pressed state. In this case, in the process of step S104, the host control unit 41 has exceeded the second duration while the pressed state of the predetermined push button switch 611 has been continued up to the present time, or has already passed since the second duration has been exceeded. Determine whether it has been released. Further, when the second reference time has not elapsed at the present time while the pressed state continues, the determination is suspended until the pressed state is released or the second reference time has elapsed.

  When it is determined that the pressing duration is not equal to or longer than the second reference time (“NO” in step S104), the processing of the host control unit 41 proceeds to step S108. If it is determined that the time is equal to or longer than the second reference time (“YES” in step S104), the host control unit 41 restarts the satellite radio wave reception processing unit 50 (step S105). The host control unit 41 outputs a positioning operation command (operation execution command related to acquisition of current position information) to the restarted satellite radio wave reception processing unit 50 (step S106). At this time, the host control unit 41 outputs the current date and time information previously corrected as the current date and time to the satellite radio wave reception processing unit 50.

  The host control unit 41 waits for an input from the satellite radio wave reception processing unit, and acquires information related to the current position (step S107). The host control unit 41 appropriately performs necessary processing based on the acquired current position information, for example, a display operation of the current position by the display unit 62 (a display operation of information related to the acquired date and time information), a local time setting Make changes. At this time, since date and time information more accurate than in step S103 is obtained, the host control unit 41 corrects and displays the date and time again. Alternatively, when acquiring the current position information, the host control unit 41 may not acquire the date / time information again. Then, the processing of the host control unit 41 proceeds to step S108.

When the process proceeds to step S108, the host control unit 41 stops the operation of the satellite radio wave reception processing unit 50 (step S108). Then, the host control unit 41 ends the reception operation control process.
Among these, the processing of steps S102 and S103 constitutes a first reception control step (first reception control means) in the reception operation control method (program) of the electronic timepiece 1 of the present embodiment, and steps S104, S106, and S107. The process constitutes a second reception control step (second reception control means).

FIG. 4 is a flowchart showing a control procedure by the module control unit 52 of the reception control process executed in the satellite radio wave reception processing unit 50.
This reception control process is activated and started when the host radio wave reception processing unit 50 is activated by the host control unit 41.

  When the reception control process is started, the module control unit 52 performs initial setting (step S201), and sets an acquisition target in accordance with an instruction related to the acquisition target input from the host control unit 41. Further, the module control unit 52 sets the number of target satellites N, which is the number of positioning satellites to be received according to the acquisition target (step S202). Here, the target satellite number N is “1” when the date and time information is an acquisition target, and is “3” when the current position information is an acquisition target. Alternatively, as described above, the number N of target satellites may be set to “4” when the current position information is an acquisition target.

  The module control unit 52 activates the reception unit 51 to start a reception operation. The module control unit 52 starts a radio wave capturing operation from the positioning satellite (step S203). At this time, the module control unit 52 can prioritize the positioning target positioning satellites when there is ephemeris (orbit information) data or the latest acquisition information.

  The module control unit 52 determines whether the current acquisition operation is being performed and a radio wave of the positioning satellite has been newly acquired (step S204). When it is determined that a new radio wave has been captured (“YES” in step S204), the module control unit 52 starts a tracking operation for the captured radio wave (step S205). Then, the process of the module control unit 52 proceeds to step S206. If it is determined that the capturing operation is not being performed, or the capturing operation is being performed but no new radio wave is captured ("NO" in step S204), the process of the module control unit 52 proceeds to step S206. To do.

  The module control unit 52 determines whether or not the number of captured radio waves is equal to or greater than the number N of target satellites (step S206). If it is determined that the number of target satellites is not equal to or greater than N (“NO” in step S206), the process of the module control unit 52 returns to step S204.

  When it is determined that the number of target satellites is N or more (“YES” in step S206), the module control unit 52 ends the capturing operation (step S207). The module control unit 52 determines whether or not necessary information corresponding to the acquisition target is acquired in the tracking operation (step S208). If it is determined that necessary information has not been acquired (“NO” in step S208), the process of the module control unit 52 returns to step S204.

  If it is determined that the necessary information has been acquired (“YES” in step S208), the module control unit 52 acquires the result relating to the content that is the acquisition target, and the host control unit at an appropriate timing. 41 (step S209). The module control unit 52 stops the operation of the receiving unit 51 and ends the receiving operation (step S210). Then, the module control unit 52 ends the reception control process.

As described above, the electronic timepiece 1 according to the first embodiment includes the receiving unit 51 that receives radio waves from the positioning satellite, the control unit including the host control unit 41 and the module control unit 52, and the operation reception that receives user operations. Unit 61. When the duration of the pressing operation of the predetermined push button switch 611 received by the operation receiving unit 61 becomes equal to or longer than the predetermined first reference time (1.5 seconds), the control unit When the operation related to the acquisition of information is started and the duration is equal to or longer than the second reference time (3.0 seconds) longer than the first reference time, the acquired date / time information is To perform operations related to acquisition of current position information.
As a result, provisional date and time correction information can be obtained midway before positioning is completed, particularly at an early time from the start of reception, so that a minimum reception result can be obtained quickly. In particular, it is possible to avoid a situation in which no result is obtained even when the receiving operation is terminated without operating to the end. In addition, since the date and time information acquisition operation can be started before it is determined whether or not to perform the positioning operation, the time until the positioning operation is completed is not unnecessarily prolonged.
Therefore, it is possible to improve user convenience related to information acquisition by radio wave reception.

  In addition, the control unit uses the acquired date / time information in the operation related to the acquisition of the current position information. That is, since the calculation process for calculating the current position is performed using the provisionally corrected date and time, the current position information with higher accuracy can be acquired by more reliably and quickly converging to the current position.

In addition, when the duration time is equal to or longer than the second reference time (3.0 seconds), the control unit restarts the receiving unit 51 (satellite radio wave reception processing unit 50) after acquiring the date and time information, and The operation related to the acquisition of information is started.
Since operations are switched by such simple processing, control is not complicated.

Further, in the reception operation control method of the electronic timepiece 1 according to the present embodiment, the duration of the pressing state of the predetermined push button switch 611 received by the operation receiving unit 61 is longer than the predetermined first reference time (1.5 seconds). In this case, the first reception control step for starting the operation related to the acquisition of the date / time information by the receiving unit 51, the duration time becomes equal to or longer than the second reference time (3.0 seconds) longer than the first reference time. In some cases, after the date / time information is acquired, a second reception control step of performing an operation related to acquisition of the current position information using the acquired date / time information is included.
Thereby, provisional date and time correction information is obtained midway before the positioning is completed. In addition, it is possible to start the reception operation at an early stage before the duration of the pressing state of the predetermined push button switch 611 by the user is determined. By using this for display or the like, the user can be made to know the progress of the reception status more appropriately. Therefore, it is possible to improve user convenience related to information acquisition by radio wave reception.

In addition, the program 641 of the present embodiment is such that the duration of the pressing state of the predetermined push button switch 611 received by the operation receiving unit 61 is the predetermined first reference time (1.5 seconds). When it becomes above, the 1st reception control means which starts operation concerning acquisition of the date information by receiving part 51, the 2nd standard time (3.0 seconds) longer than the 1st standard time becomes longer than the 1st standard time In such a case, after the date / time information is acquired, it is made to function as second reception control means for performing an operation related to acquisition of the current position information.
As described above, reception control can be easily performed by installing a program for improving user convenience and causing the control unit to perform a control operation in software.

[Second Embodiment]
Next, an electronic timepiece according to a second embodiment will be described.
The functional configuration of the electronic timepiece 1 according to the second embodiment is the same as that of the electronic timepiece 1 according to the first embodiment.

Next, an information acquisition operation by radio wave reception in the electronic timepiece 1 of the second embodiment will be described.
In this electronic timepiece 1, when date and time information is acquired in a state where an acquisition (positioning) command for current position information has been issued, information related to acquisition may be displayed and acquisition of information related to the current position may be continued. Check whether or not.

FIG. 5 is a flowchart showing a control procedure by the host control unit 41 of the reception operation control process executed by the electronic timepiece 1 of the present embodiment.
In this reception operation control process, steps S111 and S112 are added as compared with the reception operation control process in the electronic timepiece 1 of the first embodiment. The other processes are the same, and the same processing contents are denoted by the same reference numerals and description thereof is omitted.

  Following the processing of step S106, the host control unit 41 acquires radio wave capture information from the positioning satellite from the satellite radio wave reception processing unit 50 (module control unit 52), and continues the operation related to the acquisition of the current position information. Display for inquiring whether or not to continue is performed by the display unit 62 (step S111). The host control unit 41 waits for an input operation to the operation receiving unit 61 and determines whether or not there is an input operation instructing continuation (step S112). If it is determined that the input operation does not instruct to continue (do not continue) ("NO" in step S112), the process proceeds to step S108. If it is determined that there is an input for instructing to continue (“YES” in step S112), the processing of the host control unit 41 proceeds to step S107. Note that when there is no input operation for a predetermined time or when the current position information is acquired without any input operation, the processing of the host control unit 41 may automatically move to step S107.

FIG. 6 is a flowchart showing a control procedure by the module control unit 52 of the reception control process executed by the electronic timepiece 1 of the present embodiment.
In this reception control process, compared with the reception control process in the electronic timepiece 1 of the first embodiment, the processes in steps S202 and S206 are replaced with the processes in steps S202a and S206a, respectively, and the processes in steps S221 and S222 are performed. Have been added. The other processes are the same, and the same processing contents are denoted by the same reference numerals and description thereof is omitted.

  Following the processing in step S201, the module control unit 52 sets an acquisition target (step S202a). Here, the module control unit 52 does not set the target satellite number N. Then, the process of the module control unit 52 proceeds to step S203. At this time, when the acquisition target is the current position information, the module control unit 52 preferentially captures the radio wave previously captured at the time of date / time information acquisition using the capture information stored in the process of step S222 described later. Can be targeted.

  When branching to “NO” in the process of step S204, or following the process of step S205, the module control unit 52 determines whether or not the number of captured radio waves is four or more (step S206a). If it is determined that the number is not 4 or more (“NO” in step S206a), the process of the module control unit 52 proceeds to step S208.

  When it is determined that the number of captured radio waves is 4 or more (“YES” in step S206a), the process of the module control unit 52 proceeds to step S207. After the process of step S207, the module control unit 52 determines whether the acquisition target is date information (step S221). If it is determined that it is not date and time information (“NO” in step S221), the processing of the module control unit 52 proceeds to step S208. When it is determined that the date and time information is “YES” in step S221, the module control unit 52 causes the storage unit 53 to store information on the transmission source positioning satellite of the captured radio wave (step S222). This information (information on the captured radio wave) may include information such as reception intensity and SN ratio (radio wave capture information) in addition to the positioning satellite identification number. Then, the process of the module control unit 52 proceeds to step S208.

  As described above, in the electronic timepiece 1 of the second embodiment, the control unit stores information related to the radio wave captured in the operation related to the acquisition of the date / time information and performs the operation related to the acquisition of the current position information. Takes the captured radio wave as a priority for capture. In this way, by effectively using the radio wave reception information in the date and time acquisition operation, it is possible to shorten the time and labor required for the positioning operation, particularly the radio wave acquisition operation, and acquire the current position information without waiting for the user as much as possible. Can be completed.

  In addition, the display unit 62 is provided, and the control unit relates to the acquired date and time information when the duration of the pressed state of the predetermined push button switch 611 is equal to or longer than the second reference time (3.0 seconds). Information is displayed on the display unit 62, and it is determined whether or not to continue (continue) the operation related to the acquisition of the current position information according to the input operation from the operation receiving unit 61. In other words, if it is confirmed that there is no time difference between the corrected date and time in the local time, it is no longer necessary to update the local time setting. In such a case, the user knows from the result display related to the acquisition of the date and time information, and the user can determine again whether the positioning operation is really continued. In this case, since it is rare for the user to wait for a large amount of time until the date and time are acquired, the user is not required to request a large waiting time. Further, since the date and time are acquired, nothing is obtained and the operation is not terminated, and the user's feeling of labor can be reduced. In addition, since the reception operation related to positioning is continued while the continuous approval operation is not performed, in the situation where the acquisition command of the current position information is originally acquired, the user's operation is delayed or the user does not operate The operation related to the acquisition of the current position is not unnecessarily prolonged. Further, since the user who does not want to perform the input operation again is not forced to perform an additional input operation, unnecessary effort is not increased. And when a user judges that it is unnecessary, since the long-time receiving operation concerning acquisition of present position information can be stopped quickly, unnecessary power consumption can be suppressed.

  In addition, the information related to the acquisition of the date / time information includes radio wave capture information from the positioning satellite. Thus, by presenting to the user including information such as the number of captured radio waves, the reception intensity of the captured radio waves, and the SN ratio, it is possible to allow the user to more appropriately determine whether the positioning operation is actually performed. it can.

[Third Embodiment]
Next, an electronic timepiece according to a third embodiment will be described.
Since the electronic timepiece 1 of the third embodiment has the same functional configuration as that of the electronic timepiece 1 of the first embodiment, the same reference numerals are given and description thereof is omitted.

Next, an information acquisition operation by radio wave reception in the electronic timepiece 1 of the third embodiment will be described.
The electronic timepiece 1 can shift from the information acquisition operation related to the date and time to the information acquisition operation related to the current position without restarting during the acquisition of the date and time information.

FIG. 7 is a flowchart showing a control procedure by the host control unit 41 of the reception operation control process in the electronic timepiece 1 of the present embodiment.
Compared with the reception operation control process executed by the electronic timepiece 1 of the first embodiment, the reception operation control process is performed by adding the processes of steps S121 to S123, deleting the processes of steps S104 and S105, The process of step S106 is replaced with the process of step S106a. The other processes are the same, and the same processing contents are denoted by the same reference numerals and description thereof is omitted.

  Following the processing in step S102, the host control unit 41 determines whether or not 3.0 seconds or more have elapsed from the start timing of the pressing state of the predetermined push button switch 611 (step S121). If it is determined that 3.0 seconds or more have not elapsed ("NO" in step S121), the host control unit 41 determines whether the pressing operation is released and the pressing state is terminated (step S121). S122). If it is determined that it has not been released (“NO” in step S122), the processing of the host control unit 41 returns to step S121. If it is determined that it has been released (“NO” in step S121), that is, if it is determined that the duration of the pressed state is less than 3 seconds, the processing of the host control unit 41 proceeds to step S103. To do.

  When it is determined in the determination process in step S121 that three seconds or more have elapsed from the start timing of the pressed state (“YES” in step S121), the host control unit 41 issues a positioning command to the module control unit 52. Output (step S106a). Then, the processing of the host control unit 41 proceeds to step S103.

  When the date and time information is acquired from the satellite radio wave reception processing unit 50 in the process of step S103 (step S103), the host control unit 41 determines whether or not a positioning command has been transmitted to the satellite radio wave reception processing unit 50. (Step S123). If it is determined that the positioning command has been transmitted (“YES” in step S123), the processing of the host control unit 41 proceeds to step S107. If it is determined that a positioning command has not been transmitted (“NO” in step S123), the processing of the host control unit 41 proceeds to step S108.

  FIG. 8 is a flowchart showing a control procedure by the module control unit 52 of the reception control process executed by the satellite radio wave reception processing unit 50 of the electronic timepiece 1 of this embodiment.

  Compared with the reception control process executed by the electronic timepiece 1 of the first embodiment, this reception control process is added with the processes of steps S231 to S233, the process of step S202 is replaced with the process of step S202b, and Instead of the processes of steps S208 and S209, the processes of steps S208a, S209a, S208b, and S209b are executed. The other processes are the same, and the same processing contents are denoted by the same reference numerals and description thereof is omitted.

  Following the processing in step S201, the module control unit 52 sets the acquisition target to the date and time, and sets the number of target satellites N to “1” (step S202b). Then, the process of the module control unit 52 proceeds to step S203.

  When branching to “NO” in step S204 or after the process of step S205, the module control unit 52 determines whether or not a capture command is input from the host control unit 41 (step S231). If it is determined that no input has been made (“NO” in step S231), the processing of the module control unit 52 proceeds to step S206. If it is determined that it has been input (“YES” in step S231), the number N of target satellites is changed to “3” (step S232). That is, the module control unit 52 starts and executes the number of radio wave capturing operations necessary for acquiring the current position information even before the date / time information is acquired. Then, the process of the module control unit 52 proceeds to step S206.

  When the process branches to “NO” in the process of step S206 or after the process of step S207, the module control unit 52 determines whether or not information related to the date and time has been acquired (step S208a). If it is determined that it has not been acquired (“NO” in step S208a), the process of the module control unit 52 proceeds to step S208b.

  If it is determined that the date and time information has been acquired (“YES” in step S208a), the module control unit 52 acquires the date and time and outputs the requested date and time information to the host control unit 41 (step S209a). ). The module control unit 52 determines whether or not a positioning command has been input (step S233). If it is determined that it has not been acquired (“NO” in step S233), the processing of the module control unit 52 proceeds to step S210. If it is determined that it has been acquired (“YES” in step S233), the processing of the module control unit 52 proceeds to step S208b.

  After branching from step S208a or step S233 to step S208b, the module control unit 52 determines whether information related to positioning has been acquired (step S208b). If it is determined that it has not been acquired (“NO” in step S208b), the process of the module control unit 52 returns to step S204. When it is determined that it has been acquired (“YES” in step S208b), the module control unit 52 acquires current position information and outputs the current position information to the host control unit 41 (step S209b). Then, the process of the module control unit 52 proceeds to step S210.

  As described above, in the electronic timepiece 1 according to the third embodiment, the control unit determines that the duration of the pressing state of the predetermined push button switch 611 during the operation related to the acquisition of the date / time information is the second reference time (3.0). (Seconds) or more, the number (3 or 4) of radio wave capturing operations necessary for the operation related to the acquisition of the current position information is performed before the acquisition of the date / time information. In this way, even when the date and time are being acquired, by proceeding with the operation of capturing radio waves from a plurality of positioning satellites, it is possible to immediately shift to the receiving operation related to the acquisition of the current position information after the date and time information is acquired. it can.

However, other operations, for example, the rotation operation of the crown or the contact time to a predetermined position of the touch panel are performed. The reception operation control may be performed based on the above.

  Further, in the above embodiment, when the satellite radio wave reception processing unit 50 is restarted, the capture information at the time of acquisition of the date / time information is stored and pre-recaptured. However, the present invention is not limited to this. .

  Further, in the above embodiment, when the user is asked for approval during the current position information acquisition operation, the operation is continued even if there is no approval. However, the operation may be stopped without fail or depending on conditions. . For example, if three or more positioning satellites are not captured during the date and time acquisition operation, user approval may be required before performing the capture operation again.

  In addition, the radio wave capture information is displayed when the user's approval is requested. However, when the display unit 62 has a sufficient display capability with a pointer-type electronic timepiece or the like, it may not always be displayed. . Alternatively, a function hand for performing display related to a functional operation such as a reception status may be provided separately from the pointer used for displaying the time.
