Description

The present invention relates to an electronic timepiece, a time correction method, and a program.

  Conventionally, some electronic timepieces have a function of acquiring accurate date and time information from the outside and correcting the counting date and time. With such a function, it is possible to omit the use of a technique for increasing the counting accuracy of the built-in clock of the electronic timepiece or the need for correcting the built-in clock by a user operation.

  Examples of sources of accurate date and time information externally include standard radio waves, positioning satellites, mobile phones and smartphones. For electronic watches, especially portable watches such as electronic watches, it is difficult to perform high-speed communication that leads to an increase in power consumption and memory size due to restrictions on the size, weight, and heat generation of electronic watches. In addition, there is a problem that it is difficult to perform complicated transmission / reception operations due to operational problems. Therefore, in an electronic timepiece, conventionally, fixed data having a small size related to date / time information is acquired mainly using wireless communication, and the date / time is corrected. For example, Patent Document 1 discloses a technique for receiving an accurate date and time from a mobile phone using Bluetooth communication (registered trademark: Bluetooth) at the same timing.

  Among the suppliers of date and time information, the local time corresponding to the reception area of the standard radio wave, the connection area of the mobile phone, and the like is acquired from the standard radio wave, the mobile phone, the smartphone, and the like. In this case, daylight saving time has been implemented in some parts of the world, and if counting the time with an electronic watch continues with the acquired date and time, the counting time and the actual local time will be There is a problem that a gap occurs between the two. On the other hand, there is an electronic timepiece that can automatically switch and display the local time according to the set cities and areas around the world. In such an electronic timepiece, daylight saving time implementation information corresponding to a city or area is stored in advance, and the local time can be corrected at the start or end timing of daylight saving time.

  However, there are various settings such as daylight saving time start timing, end timing, and shift time from the standard time during the implementation period, and these settings are often changed due to political, religious, and economic circumstances. In recent years, such setting information can be easily obtained in electronic devices connected to the Internet. However, in the case of electronic watches, particularly portable small watches, this kind of daylight saving time setting has been used so far. It was difficult to change, and it was very complicated and troublesome to manually correct the settings. On the other hand, in such an electronic timepiece, if the user manually corrects the daylight saving time in summer time, it may place an extra burden on the user or cause the user to forget to correct it and cause confusion. It was what you get. Due to these causes, there is a problem that the electronic timepiece cannot easily maintain an accurate local time count reflecting daylight saving time.

An object of the present invention is to provide an electronic timepiece, a time correction method, and a program that can easily maintain accurate local time counts.

In order to achieve the above object, the present invention

It is. Alternatively, these data are at least in a fully compatible format.

  The built-in clock 15 is a counter that counts and holds the current time. This current time may be counted by software by the operation of the CPU 11 and stored in a RAM or the like. The built-in clock 15 has an RTC (Real Time Clock). When the smartphone 10 is restarted after the power of the smartphone 10 is turned off, date / time data is acquired from the RTC and counting is resumed. The smartphone 10 reads the current time of the built-in clock 15, calculates the local time according to the time zone and daylight saving time setting as necessary, and displays it on the display unit 16 or uses it for various processes. In addition, various operations are performed by comparing the current time with the set times for various functions. The current time data of the built-in clock 15 is corrected by time data acquired from the base station at any time during communication with the mobile phone communication base station by the RF transceiver circuit 22.

  The bus 29 is a data path that connects the CPU 11 and each component inside the smartphone 10 so that signals can be transmitted and received.

Next, calculation in local time in the electronic timepiece 40 of this embodiment will be described.
In this electronic timepiece 40, based on the time zone setting information at the current position stored in the area setting storage unit 432, the time difference is applied to the date and time counted by the time measuring unit 46 to calculate the local time based on the standard time. To do. Further, the daylight saving time implementation information at the current position is read from the daylight saving time setting storage unit 431, and it is determined whether or not the calculated local time is in the daylight saving time. In this case, the shift time is added to calculate the local time in the daylight saving time.
Once the local time is calculated, as described above, the local time is held in the RAM 43 or the like and can be counted together with the date and time counted by the time measuring unit 46. In this case, it is determined whether or not it is equal to the start date / time of daylight saving time or the end date / time of daylight saving time every predetermined time, for example, every 15 minutes. If they are equal, the shift time is added or the added shift time is set. Make corrections to restore.

FIG. 4 is a chart showing table data relating to setting information at the local time.
As described above, the RAM 43 includes the daylight saving time setting storage unit 431 and the area setting storage unit 432. The storage unit 14 includes a daylight saving time setting storage unit 142 and an area setting storage unit 143. As shown in FIG. 4 (a), the daylight saving time setting storage unit 431 and the daylight saving time setting storage unit 142 are configured to include information regarding the start date and time and the end date and time of daylight saving time (daylight saving time execution period) for each execution pattern. (Here, No. 1 to No. 24) are stored. In addition, the daylight saving time setting storage unit 431 and the daylight saving time setting storage unit 142 are provided with a spare memory number 25 or later that can additionally store the execution pattern when a new execution pattern occurs. Number 0 corresponds to daylight saving time not being implemented. Also, here, when the end of daylight saving time is the next year in the southern hemisphere, the year crossing flag is set to “1”, and when the daylight saving time starts and ends in the same year in the northern hemisphere, Is set to “0”. Also, the daylight saving time start timing and end timing may be determined based on the local time, or may be determined based on the UTC time. When the UTC time is based, the “LT / UTC” The selection flag is set to “1”.

  As shown in FIG. 4B, in the area setting storage unit 143, as the above-mentioned local time setting, a number (selection information) indicating a daylight saving time implementation pattern for each city that can be set in advance is a time zone and shift time information. Are stored in association with each other. In addition, a DST setting value, which is a parameter related to daylight saving time application setting (whether or not daylight saving time is set based on an input operation) is determined for each city, and is included in the local time setting and stored in the area setting storage unit 143. Is done. This DST set value is a setting “AUTO” that is automatically determined according to the setting information stored in the above-described daylight saving time setting storage unit 431 (and daylight saving time setting storage unit 142), regardless of the setting information. It is one of the values “0” to “2” corresponding to the setting “ON” to be set and the setting “OFF” to be set to the non-execution state regardless of the setting information.

  The area setting storage unit 432 stores settings in a predetermined number of cities including at least the city currently selected by the electronic clock 40 among the settings in the plurality of cities stored in the area setting storage unit 143. The predetermined number of values that can be stored is determined in accordance with the capacity of the RAM 43 of the electronic timepiece 40. For example, “1”, that is, only the currently selected city may be used, or a regular business trip may be used. Considering the number of cities to be operated, it may be about “2” to “4”. Here, a case will be described in which only settings relating to one city corresponding to the current position are stored.

  Each of the data stored in the daylight saving time setting storage units 431 and 142 and the area setting storage units 432 and 143 includes version information (information indicating an update status), here, a simple 4 such as “0003”. A digit version number is attached. A value in a finite range may be repeatedly used for this version number.

  Here, in the electronic timepiece 40, the user can manually change the DST setting by an input operation to the operation unit 47. As a result, when the daylight saving time implementation period and the implementation period are suddenly changed and the latest information is not supported, or when the user intentionally switches whether to reflect the implementation of daylight saving time at the current position You can manually switch between daylight saving time and non-daylight saving time. In addition, the user can manually start the local time setting management application 141 by an input operation to the operation unit 18 of the smartphone 10 and transmit an instruction to change the DST setting to the electronic timepiece 40.

Next, the update operation of the daylight saving time setting in the communication system 1 of the present embodiment will be described.
In this communication system 1, the smartphone 10 connects to the external data server 90 at preset intervals to acquire data on time zone settings and daylight saving time implementation settings (collectively referred to as local time settings). When there is a difference between the data currently stored in the daylight saving time setting storage unit 142 and the area setting storage unit 143 and the acquired data, 1 is added to the version number to add the latest acquired data. Remembered. The smartphone 10 can be connected to an external network (Internet) via a base station or access point in many time zones, and the connection interval can be set flexibly, but at least twice a year, the northern and southern hemispheres. It is preferable that the connections are made before the spring season (March to April, September to October) when summer time starts. Further, the connection intervals do not have to be equal, and for example, they may be connected a plurality of times in a concentrated manner in the above-described spring period. As described above, by acquiring the local time setting from the external data server 90 at an appropriate timing and interval via the Internet, the smartphone 10 can easily hold the latest or latest daylight saving time implementation information.

  Updating of the setting data in the daylight saving time setting storage unit 142 and the area setting storage unit 143 is not particularly limited, but is performed according to the following policy. First, (1) when the implementation period of daylight saving time in some cities is changed to be the same as the implementation period already implemented in other cities, the area setting storage unit 143 sets each of the cities to The associated DST number is changed. Next, (2) when the implementation period of the daylight saving time is changed in all cities that implement daylight saving time in the implementation period related to one DST number, the DST stored in the daylight saving time setting storage unit 142 The number settings are changed. (3) When the implementation time of daylight saving time in some cities is changed to a new period different from the implementation periods implemented in other cities, the setting of the new implementation period is stored in the daylight saving time setting The DST number associated with the partial city stored in the area setting storage unit 143 is additionally stored in the spare memory in the unit 142, and is changed to the DST number of the spare memory.

  On the other hand, at a preset timing and / or by a predetermined input operation by the user to the operation unit 47 in the electronic timepiece 40, communication connection is made between the electronic timepiece 40 and the smartphone 10, and the smartphone 10 transmits the electronic timepiece. The date / time data is transmitted to 40 and the date / time of the time measuring unit 46 is corrected. At this time, the data of the daylight saving time setting storage unit 431 and the area setting storage unit 432 held in the electronic timepiece 40 (the local time setting) is stored in the smartphone 10 and the data of the daylight saving time setting storage unit 142 and the area setting storage unit 143 is stored. When the current position (city) specified by the smartphone 10 is different from the position set by the electronic clock 40, the daylight saving time setting storage unit 142 and the area setting storage unit 143 Data is transmitted along with the version number, and the local time setting of the electronic clock 40 is updated.

FIG. 5 is a sequence diagram relating to a communication procedure between the electronic timepiece 40 and the smartphone 10.
In the update operation of the daylight saving time setting in the communication system 1 of the present embodiment, the electronic timepiece 40 requests the smartphone 10 for communication connection by Bluetooth. In response to this, the smartphone 10 responds to the electronic timepiece 40 and establishes a communication connection.

  The electronic timepiece 40 transmits the version information of the setting data (local time setting) in the daylight saving time setting storage unit 431 and the area setting storage unit 432 and the city number of the currently set city to the smartphone 10. The smartphone 10 transmits date and time information (local time) according to the date and time counted by the built-in clock 15 and the current position of the smartphone 10 to the electronic timepiece 40, and the received version information includes the daylight saving time setting storage unit 142 and If the version of the setting data in the area setting storage unit 143 is different, the setting data is transmitted. In addition, when the current positions of the smartphone 10 and the electronic timepiece 40 are different from each other, data corresponding to the current position of the smartphone 10 is transmitted among the setting data in the area setting storage unit 143. Thereafter, the connection between the electronic timepiece 40 and the smartphone 10 is released.

FIG. 6 is a flowchart showing a control procedure by the CPU 41 of the setting update process executed by the electronic timepiece 40.
This setting update process is automatically started at a preset start time and / or started in response to a predetermined input operation by the user to the operation unit 47. When the setting update process is started, the CPU 41 causes the Bluetooth module 48 to output a communication connection request by Bluetooth to the smartphone 10 (step S101).

  When the communication connection is established with the smartphone 10, the CPU 41 transmits the version information of the setting data in the daylight saving time setting storage unit 431 and the area setting storage unit 432 to the smartphone 10 from the Bluetooth module 48 and the area setting storage unit 432. The city number included in the setting data is transmitted (step S102).

CPU41 waits for the data transmission from the smart phone 10, and receives the data from the said smart phone 10 (step S103). CPU41 discriminate | determines whether the local time setting is included in the data received from the smart phone 10 in addition to date information (step S104). If it is determined that the local time setting is included (“YES” in step S104), the CPU 41 determines whether the city number has been changed from the currently set city number in the acquired local time setting. It is determined whether or not (step S105). If it is determined that it has been changed (“YES” in step S105), the CPU 41 switches the DST setting to “AUTO” and uses the obtained setting data relating to the local time setting to store the daylight saving time setting storage unit. 431 and / or the area setting storage unit 432 are updated (step S106). Then, the process of the CPU 41 proceeds to step S108. If it is determined that it has not been changed (“NO” in step S105), the CPU 41 maintains the DST setting as it is, and changes the changed part of the daylight saving time setting storage unit 431 and / or the area setting storage unit 432. Update (step S107). Then, the process of the CPU 41 proceeds to step S108.
When the smartphone 10 determines the difference in the city number and transmits the corresponding DST setting, the CPU 41 does not perform the determination process in step S105 and does not perform the determination process in step S105 and / or the area setting storage unit 432. Update should be done.

  When the process proceeds to step S108, the CPU 41 corrects the date and time (reference date and time) of the timer 46 based on the acquired date and time information, and calculates the local time based on the local time setting (step S108). Then, the process of the CPU 41 proceeds to step S110.

If it is determined in step S104 that the local time setting is not included in the received data (“NO” in step S104), the CPU 41 determines the date and time of the time measuring unit 46 based on the received date and time data. Is corrected (step S109). The local time is corrected in accordance with the date and time correction of the timing unit 46. Then, the process of the CPU 41 proceeds to step S110.
In addition, the determination regarding the presence / absence of the local time setting is, for example, that the local time setting is not received within a predetermined time, the empty data is transmitted following the predetermined header related to the transmission of the local time setting, or explicitly. This is appropriately performed depending on, for example, that a signal indicating that there is no local time setting transmission is transmitted.

  If transfering to the process of step S110, CPU41 will cancel | release the communication connection by the Bluetooth with the smart phone 10 (step S110). Then, the CPU 41 ends the setting update process.

FIG. 7 is a flowchart illustrating a control procedure by the CPU 11 of the automatic setting transmission process executed by the smartphone 10.
This automatic setting transmission process is started when a communication connection request is received from the electronic timepiece 40.

  First, the CPU 11 causes the Bluetooth module 24 to respond to the electronic timepiece 40 to establish a communication connection with the electronic timepiece 40 (step S201). The CPU 11 acquires the version information and city number of the local time setting information transmitted from the electronic timepiece 40 (step S202).

The CPU 11 determines whether or not the version acquired from the electronic timepiece 40 is different from the version of the information stored in the daylight saving time setting storage unit 142 and the area setting storage unit 143 (step S203). When it is determined that the versions are different (“YES” in step S203), the CPU 11 causes the electronic timepiece 40 to change the local time setting information to the electronic timepiece 40 using the Bluetooth module 24 (at least a portion that is changed due to a version difference (not equal). (Part) daylight saving time setting information is transmitted (step S204). Then, the process of the CPU 11 proceeds to step S206.
Here, in step S204, when only the daylight saving time setting information of the part that has changed due to the version difference is transmitted, when updating the daylight saving time setting information, the CPU 11 stores difference data that summarizes the changed part in advance. You can create it.

  When it is determined that the versions are not different (“NO” in step S203), the processing of the CPU 11 determines whether or not the acquired city number is different from the city number currently set in the smartphone 10. (Step S205, movement determination means). If it is determined that the city numbers are different (“YES” in step S205), the processing of the CPU 11 proceeds to step S206. If it is determined that the city numbers are not different (they are the same) (“NO” in step S205), the processing of the CPU 11 proceeds to step S207.

When the process proceeds to step S206, the CPU 11 reads out the area setting information of the city related to the city number set in the smartphone 10 from the area setting storage unit 143 and causes the Bluetooth module 24 to transmit the information to the electronic timepiece 40 (step). S206). Then, the process of the CPU 11 proceeds to step S207.
As described above, when the process of step S105 is omitted in the setting update process of the electronic timepiece, in the process of step S206, the CPU 11 needs to appropriately set and transmit the DST setting.

  In step S207, the CPU 11 causes the Bluetooth module 24 to transmit date / time information (local time) to the electronic timepiece 40 (step S207). The CPU 11 causes the Bluetooth module 24 to cancel the communication connection with the electronic timepiece 40 (step S208). Thereafter, the CPU 11 ends the automatic setting transmission process.

FIG. 8 is a flowchart illustrating a control procedure by the CPU 11 of the manual setting transmission process executed by the smartphone 10 when the daylight saving time setting update operation is manually performed according to the operation of the smartphone 10.
This manual setting transmission process is obtained by adding steps S200 and S211 to S215 to the above-described automatic setting transmission process, and the other processes are the same. A detailed description is omitted.

The manual setting transmission process is started when the local time setting management application 141 is activated on the smartphone 10 and an operation related to a connection command with the electronic timepiece 40 is performed on the display screen.
When the manual setting transmission process is started, the CPU 11 requests the electronic timepiece 40 for a connection operation by Bluetooth communication (step S200). The CPU 11 establishes a communication connection with the electronic timepiece according to the communication from the electronic timepiece 40 (step S201).

  Further, the CPU 11 determines whether or not a DST setting switching operation has been detected after transmitting the date and time information in the process of step S207 (step S211). If it is determined that it has been detected (“YES” in step S211), the CPU 11 changes the DST setting to the switching destination (step S212). Then, the process of the CPU 11 proceeds to step S213. If it is determined that the DST setting switching operation has not been detected (“NO” in step S211), the processing of the CPU 11 proceeds to step S213.

  In step S213, the CPU 11 determines whether or not an operation related to a transmission command for DST setting is detected (step S213). If it is determined that it has been detected (“YES” in step S213), the CPU 11 causes the Bluetooth module 24 to transmit the DST setting set at this time to the electronic timepiece 40 (step S214). Then, the process of the CPU 11 proceeds to step S215. If it is determined that it has not been detected (“NO” in step S213), the processing of the CPU 11 proceeds to step S215.

  When the process proceeds to step S215, the CPU 11 determines whether or not a local time setting end operation has been detected (step S215). If it is determined that it has been detected (“YES” in step S215), the CPU 11 ends the manual setting transmission process. If it is determined that it has not been detected (“NO” in step S215), the CPU 11 returns the process to step S211.

  9 and 10 are diagrams illustrating examples of display on the display screen of the smartphone 10 during manual execution of the local time setting management application.

  As shown in FIG. 9, the display unit 16 of the smartphone 10 displays the name on the display screen in the central portion 16 d indicating the current local time, the time difference from UTC, and the current position. Here, in New York, it is shown that the time difference of UTC-4 hours is 17:57:40 during the implementation of DST. In the lower part of the center portion 16d, an implementation period display 16b of daylight saving time set for New York and a selection screen 16c for setting DST are displayed. Here, the DST setting is AUTO, and the display of “AUTO” is highlighted on the DST setting selection screen 16c. It is shown that the time difference is calculated based on the daylight saving time implementation period from March 8, 2015 to November 1, 2015 according to this AUTO setting.

  At the lower end of the display screen, a display 16a for accepting a command for transmitting the DST setting to the electronic timepiece 40 is displayed, and a touch operation (tap) is performed in the area of the display 16a, whereby step S213 in FIG. Branches to “YES” in the determination process. On the other hand, the upper end portion 16e of the display screen indicates that the current daylight saving time setting is being performed, and the operation related to the daylight saving time setting can be exited by moving to an upper layer. Alternatively, the operation program of the local time setting application may be directly terminated.

  In the display state of FIG. 9, when OFF is selected as the DST setting on the DST setting selection screen 16c, the selected “OFF” display is highlighted as shown in FIG. The central portion 16d displays a time difference when DST is not performed and a time calculated based on the time difference. That is, the local time is UTC-5 hours, and 16:57:45, which is one hour later than the normal local time (5:57 PM) shown at the upper end of the display screen, is shown as the local time.

  FIG. 11 is a flowchart showing a control procedure by the CPU 41 of the setting update process executed by the electronic timepiece 40 when the daylight saving time setting update operation is manually performed according to the operation on the smartphone 10.

  As described above, this setting update process is a process that is started when a request for a connection operation is made from the smartphone 10, and the process of step S101 is a step with respect to the setting update process shown in FIG. It is replaced by the process of S101a, and the processes of steps S121 to S123 are added. Other processes are the same, and the same processing contents are denoted by the same reference numerals, and detailed description thereof is omitted.

  When the setting update process is started, the CPU 41 performs a communication connection operation with respect to the smartphone 10 and establishes a communication connection (step S101a). Then, the process of the CPU 41 proceeds to step S102.

  When the processing of steps S108 and S109 is completed, the CPU 41 determines whether or not data relating to the DST setting is acquired within the local time setting or separately (step S121). If it is determined that the DST setting has been acquired (“YES” in step S121), the local time is calculated again according to the changed DST setting (step S122). Then, the process of the CPU 41 proceeds to step S123. If it is determined that the DST setting has not been acquired (“NO” in step S121), the processing of the CPU 41 proceeds to step S123.

  If transfering it to the process of step S123, CPU41 will discriminate | determine whether the communication cutting | disconnection request | requirement with the smart phone 10 was received (step S123). This determination processing includes determination of whether or not to perform post-processing when communication is unilaterally disconnected by the smartphone 10. If it is determined that a disconnection request has been received (post-processing after disconnection is necessary) (“YES” in step S123), the CPU 41 performs processing related to the cancellation of the communication connection with the smartphone 10 (step S108). ). Then, the CPU 41 ends the setting update process. If it is determined that a disconnection request has not been received (post-processing after disconnection is unnecessary) (“NO” in step S123), the process of the CPU 41 returns to step S121.

  If the Bluetooth communication must be connected from the electronic timepiece 40 side, the user can perform an input operation to the operation unit 47 while the local time setting management application 141 is activated on the smartphone 10. Thus, the setting update process may be activated by the electronic timepiece 40 to transmit a communication connection request to the smartphone 10. In this case, after the date / time information and the local time setting are acquired by the electronic timepiece 40 by the signal from the smartphone 10, the communication is not immediately disconnected.

As described above, the electronic timepiece 40 of the present embodiment includes the clock unit 46 that counts the local time at the current position, the daylight saving time setting storage unit 431 that stores at least daylight saving time implementation information at the current position, the CPU 41, and the external device. A Bluetooth module 48 that communicates with a certain smartphone 10 is provided. The CPU 41 corrects the local time according to the daylight saving time implementation status at the current position as daylight saving time correction means as the daylight saving time correction means, and updates the daylight saving time execution information from the smartphone 10 by the Bluetooth module 48 as the setting update means. Is reflected in the daylight saving time implementation information in the daylight saving time setting storage unit 431.
In this way, by keeping the daylight saving time setting inside, when the daylight saving time setting is switched, it is possible to quickly correct the local time related to the switching, and even if the daylight saving time setting is updated, the smartphone 10 Therefore, the update information can be easily acquired and reflected in the stored daylight saving time setting, so that it is possible to easily maintain an accurate local time count even in the electronic timepiece 40 where it is not easy to change the daylight saving time setting. In addition, since the necessary settings can be obtained from the smartphone 10, it is not necessary to provide a large amount of setting marks on the dial or the case in the electronic timepiece 40, and the design range of the electronic timepiece 40 can be increased. Can be spread.

  Moreover, CPU41 acquires date information from the smart phone 10 as date information acquisition means, and corrects the local time which the time measuring part 46 counts based on the acquired date information as time correction means. Further, the update information of the daylight saving time implementation information is acquired together with the date / time information. In other words, in order to accurately maintain the date and time counted and displayed by the electronic clock 40, the daylight saving time implementation information can be updated together with the acquisition of date and time information that is frequently performed at least once a day. , Daylight saving time implementation information can be easily kept up to date. Therefore, it is possible to reduce the possibility that the local time is counted and displayed according to the erroneous daylight saving time.

  Further, the CPU 41 obtains local time settings related to the local time count at the current position from the smartphone 10 as local time setting acquisition means, and the daylight saving time currently being implemented worldwide as daylight saving time implementation information in the daylight saving time setting storage unit 431. Is stored. As a daylight saving time correction means, the CPU 41 selects a daylight saving time implementation period at the current position from the daylight saving time implementation information based on the acquired local time setting, and corrects the local time according to the implementation period. Accordingly, by acquiring only the information for selecting the daylight saving time implementation period according to the current position from the smartphone 10 while holding the daylight saving time setting that is not frequently changed in the electronic clock 40, the communication amount is not increased more than necessary. It is easy to count the correct local time considering daylight saving time.

  In addition, the update information for daylight saving time implementation information is acquired together with the local time setting, so that accurate daylight saving time implementation information is obtained when the calculated local time is changed or corrected to ensure accurate local time. Can be obtained.

Further, the local time setting includes information on the time zone to which the current position belongs, and the time measuring unit 46 counts the reference date and time as the reference date and time counting means, and the reference time in the acquired time zone as the local time conversion means. The local time is calculated based on the time difference from the date and time.
Therefore, when setting and displaying the world time (world clock) or the like with the electronic timepiece 40 alone, the local time in a different time zone can be easily calculated based on the information of the time zone.

In addition, the CPU 41 includes an operation unit 47 that accepts an input operation by the user, and the CPU 41 operates as a daylight saving time application selection unit in accordance with whether or not the daylight saving time correction unit is set based on the input operation to the operation unit 47. Or the local time correction is switched according to the daylight saving time implementation status at the current position obtained based on the daylight saving time implementation information.
Therefore, normally, the user corrects the local time according to the daylight saving time implementation state without worrying about the daylight saving time implementation at all, while the user does not want to intentionally display the daylight saving time. When the daylight saving time is suddenly executed or canceled and it is easier to temporarily switch manually, the user can switch the DST setting by an input operation to the operation unit 47.

  Also, the local time setting includes information indicating the current position, and the CPU 41, as daylight saving time application selection means, acquires the current position acquired and the setting that was set as the current position when the current position was acquired. If the position is different, the local time is corrected according to the daylight saving time implementation status at the current position obtained based on the daylight saving time implementation information, the current position is equal to the set position, and the input operation is performed by the user. If the setting related to whether or not daylight saving time is performed is made based on this, the local time is corrected according to whether or not daylight saving time is set. Accordingly, even when the user manually switches the DST setting, if the user moves to another time zone or daylight saving time implementation area, whether or not daylight saving time is appropriately reflected in the display time of the area. It is possible to avoid a situation in which the user does not know. In addition, local temporary daylight saving time change settings are not unnecessarily reflected in other areas.

The communication system 1 according to the embodiment of the present invention includes an electronic timepiece 40 including a Bluetooth module 48 and a smartphone 10 including a Bluetooth module 24. The Bluetooth module 48 and the Bluetooth module 24 can communicate with each other. It has become. The electronic timepiece 40 includes a clock unit 46 that counts local time at the current position, a daylight saving time setting storage unit 431 that stores at least daylight saving time implementation information at the current position, and a CPU 41. The CPU 41 serves as daylight saving time correction means. Based on the daylight saving time implementation information, the local time is corrected according to the daylight saving time implementation status at the current position, and the daylight saving time implementation information is acquired by the Bluetooth module 48 from the smartphone 10 as the setting update means. Reflect in the information. In addition, the smartphone 10 includes a daylight saving time setting storage unit 142 that stores a daylight saving time implementation period implemented in the world as daylight saving time execution information, and a CPU 11. The CPU 11 serves as a daylight saving time setting storage unit as update information transmission control means. At least the daylight saving time implementation information at the current position among the daylight saving time execution information stored in 142 is transmitted as update information to the electronic timepiece 40 by the Bluetooth module 24.
That is, in the electronic timepiece 40, based on the daylight saving time implementation information stored in the daylight saving time setting storage unit 431, the correction of the local time related to the daylight saving time implementation status at an appropriate timing and shift time even if not always connected to the smartphone 10. The update information related to the change of the daylight saving time implementation information can be easily acquired from the smartphone 10 to cope with the change of the daylight saving time implementation period. Therefore, the accurate local time count in the electronic timepiece 40 can be easily maintained without bothering the user. In particular, since the smartphone 10 and the mobile phone are used as electronic devices connected to the electronic timepiece 40, the time held by the user together with the electronic timepiece 40 can be lengthened. Settings and update information can be acquired.

  In addition, these electronic devices have better operability than the electronic timepiece 40, and the capacity of the battery and memory and the processing capacity of the CPU are higher, so it is easier to update the daylight saving time implementation information than directly using the electronic timepiece 40. Daylight saving time reflecting the daylight saving time implementation period. On the other hand, since the electronic timepiece 40 is directly connected to the Internet and does not acquire daylight saving time implementation information, it is not necessary to provide the electronic timepiece 40 with a configuration related to the Internet connection, a battery, or the like. Alternatively, an increase in power consumption can be suppressed.

In the smartphone 10, the CPU 11 uses the daylight saving time implementation information stored in the daylight saving time setting storage unit 142 of the smartphone 10 as the update application determination unit. It is determined whether it is equal to the corresponding information. In addition, when the CPU 11 determines that the daylight saving time implementation information of the electronic timepiece 40 is not equal to the corresponding part of the daylight saving time implementation information of the smartphone 10 as update information transmission control means, at least the daylight saving time implementation information at the current position is used as the update information. The data is transmitted to the electronic timepiece 40 by the Bluetooth module 24.
Therefore, since the update information is transmitted only in necessary situations such as when the daylight saving time implementation information related to the required daylight saving time implementation period is changed or updated or not held in the electronic timepiece 40, daylight saving time that does not change unnecessarily. Only the necessary information can be quickly held in the electronic timepiece 40 without repeatedly transmitting the execution information.

In addition, the local time setting management application 141 according to the embodiment of the present invention uses the computer of the smartphone 10 including the Bluetooth module 24 that communicates with the electronic timepiece 40 as daylight saving time implementation information. Update information transmission control that causes the Bluetooth module 24 to transmit at least the daylight saving time implementation information at the current position among the daylight saving time execution information stored in the daylight saving time setting storage unit 142 and the daylight saving time setting storage unit 142 to be stored as update information to the electronic timepiece 40. Function as a means.
By installing and operating such a local time setting management application 141 on the smartphone 10 or the like, the electronic timepiece 40 can easily provide appropriate daylight saving time implementation information, and the electronic timepiece 40 can accurately count the local time. I can do it.

Further, the update application determination means for determining whether or not the daylight saving time implementation information held in the electronic timepiece 40 is equal to the corresponding information among the daylight saving time implementation information stored in the daylight saving time setting storage unit 142 for the computer of the smartphone 10. The update information transmission control means, when the update application determination means determines that they are not equal, the Bluetooth module 24 uses at least a portion that is not equal (changes) in the daylight saving time implementation information as the update information. The electronic timepiece 40 is transmitted.
In this way, it is determined whether the daylight saving time implementation information held in the electronic clock 40 in the smartphone 10 is old or not, and the daylight saving time implementation information related to the daylight saving time implementation period is changed or updated, or is not held in the electronic clock 40 By transmitting the update information only when update information such as a case is necessary, the daylight saving time implementation information can be appropriately updated without requiring the electronic timepiece 40 to perform unnecessary data communication. Further, by transmitting only the changed portion to the electronic timepiece 40, the amount of data communication can be further reduced, and the electronic timepiece 40 can easily maintain an accurate local time count.

Further, the computer of the smartphone 10 stores local time setting storage means for storing selection information for selecting the daylight saving time implementation period in each preset area in the world from daylight saving time implementation information, and local time setting at the current position. Function as local time setting transmission control means for transmitting the electronic timepiece 40 to the electronic timepiece 40 by the Bluetooth module 24, and the update information transmission control means determines whether to apply the update when transmitting the local time setting at the current position by the Bluetooth module 24. If it is determined that the daylight saving time implementation information of the electronic clock 40 and the smartphone 10 is not equal, the electronic timepiece 40 includes at least the daylight saving time implementation information at the current position among the daylight saving time implementation information stored in the daylight saving time setting storage unit 142. To send to.
That is, when the current position of the smartphone 10 changes, the electronic timepiece 40 is easily switched to the local time count related to the changed current position, and the daylight saving time implementation information corresponding to the local time of the switching destination is displayed. If it is changed to the one held after 40, the daylight saving time implementation information is transmitted to the electronic timepiece 40 at least. Thereby, it is not necessary to measure the current position with the electronic timepiece 40 itself or to allow the user to perform an input operation, and the electronic timepiece 40 can easily obtain the local time setting according to the current position. The local time can be counted. In addition, since the latest daylight saving time implementation information corresponding to the current position is transmitted as necessary at this time, the electronic timepiece 40 can also calculate the local time reflecting the daylight saving time according to the latest daylight saving time implementation information. I can do it.

  Further, since the local time setting includes shift time information to be shifted during the daylight saving time implementation period, it is not necessary to include the shift time information in the daylight saving time implementation information, and the amount of data stored in the daylight saving time setting storage unit 431 is reduced. I can do it.

  In addition, since the local time setting includes the setting of the time zone corresponding to the current position, not only the local time is accurately counted, but also the information of the time zone set by the user of the electronic timepiece 40 is known. It can also be obtained. Further, when the local time setting is transmitted from the smartphone 10 to the electronic timepiece 40, the local time that accurately reflects the change is calculated even when the time zone to which the current position belongs is changed as in the daylight saving time implementation information. You can know if you are.

  Further, the current position acquisition means for acquiring the current position of the computer of the smartphone 10 and a movement for determining whether or not the acquired current position is the same as the set position set in the electronic timepiece 40 as the current position at the time of acquisition. The local time setting transmission control means causes the electronic timepiece 40 to transmit the local time setting by the Bluetooth module 24 when it is determined that the current position and the setting position are not the same. As described above, regarding the local time setting, the local time setting is transmitted from the smartphone 10 to the electronic timepiece 40 only when the user of the electronic timepiece 40 and the smartphone 10 moves and the time zone or daylight saving time setting changes. It is possible to prevent an increase in load and load of transmitting unnecessary information many times.

Also, the update information transmission control means sets the switching setting as to whether or not to correct the local time according to the daylight saving time implementation information in the electronic timepiece 40 when it is determined that the current position and the set position are the same. The setting at 40 is maintained, and if it is determined that they are not the same, the electronic timepiece 40 is set to perform correction for local time according to the daylight saving time implementation information.
Therefore, even when the user manually switches the DST setting on the electronic timepiece 40, when the user moves to another time zone or daylight saving time implementation area, the daylight saving time is appropriately reflected in the display time of the area. It is possible to avoid a situation in which the user does not know whether or not it is done. In addition, local temporary daylight saving time change settings are not unnecessarily reflected in other areas.

  Further, the movement determination unit obtains the set position by causing the Bluetooth module 24 to receive information related to the set position transmitted from the electronic timepiece 40. Therefore, even if the electronic device connected to the electronic timepiece 40 is other than the smartphone 10, it is possible to easily determine the difference from the current position and reliably determine the movement, so that the electronic timepiece 40 can detect the region at the new current position. The time setting can be acquired accurately.

In addition, the computer of the smartphone 10 functions as an update information acquisition unit that acquires the daylight saving time implementation information updated from the outside, and the update information acquisition unit acquires the daylight saving time implementation information each time new daylight saving time execution information is acquired. A version number indicating the update status is generated, and the update application determining means stores the version number indicating the update status of the daylight saving time implementation information when the daylight saving time execution information is transmitted to the electronic clock 40 and the daylight saving time setting storage unit 142. The version number indicating the update status of the daylight saving time implementation information is compared.
Thereby, in the smart phone 10, since what kind of update was made when and which update information was transmitted with respect to the electronic timepiece 40 can be judged easily, the daylight saving time implementation information hold | maintained at the electronic timepiece 40 is obtained. It is possible to easily determine whether or not the latest information and to transmit update information as necessary. In particular, by using a simple index such as version information of daylight saving time implementation information, the labor involved in determining the update status becomes easier.

  Information indicating the update status of the daylight saving time implementation information when the daylight saving time execution information is transmitted to the electronic timepiece 40 is received from the electronic timepiece 40 by the Bluetooth module 24. That is, since the electronic clock 40 itself holds the update status related to the daylight saving time implementation information in the daylight saving time setting storage unit 431, the update status of the electronic clock 40 and the smartphone 10 can be managed separately and whether there is a difference easily. Judgment can be made.

In addition, when the update information acquisition means is changed to a new implementation period in a part of the plurality of areas corresponding to the implementation period of one daylight saving time in the obtained summer time implementation information, When the implementation period is updated to add to the daylight saving time setting storage unit 142 and the implementation period in all areas corresponding to one implementation period is changed to a new implementation period, the changed implementation period is set to daylight saving time. An update for overwriting is performed in the storage unit 142.
In this way, by suppressing the portion added to the changed portion to be small, it is possible to efficiently store the memory capacity allocated to the daylight saving time setting storage unit 142 more than necessary.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, in the above embodiment, the electronic timepiece 40 holds data for all daylight saving time implementation periods in the world, but only necessary portions may be held. Even if all data is held, only necessary portions may be updated. In this case, the daylight saving time implementation information corresponding to the newly applied daylight saving time implementation period may be acquired regardless of whether or not there is an update.

  In the above embodiment, the daylight saving time execution information is acquired together with the date and time information acquired from the smartphone 10, but may be acquired separately.

  In the above embodiment, the shift time information during the daylight saving time implementation period is acquired as the local time setting, but may be included in the daylight saving time implementation information. In addition, regarding the time zone and city information, not all data may be acquired from the smartphone 10, but only parameters for referring to data stored in the ROM 42 or the RAM 43 of the electronic timepiece 40 may be acquired.

  In the above embodiment, the local time setting is acquired from the smartphone 10, but the current position information is acquired by itself or from the outside, and the local time is determined based on the table data stored in advance based on the current position. You may set the hour.

  The current date and time acquired from the external device may be local time at the current position, or may be acquired as UTC date and time. In this case, the electronic timepiece 40 may continue to count the acquired local time, or once convert it to UTC date / time or internal count value, correct the date / time counted by the time measuring unit 46, and then convert it again to local time. You may do it. In addition, when the local time is acquired, it is only necessary to specify the daylight saving time implementation period, and information such as the time zone and the current position may not be held in the electronic timepiece 40.

  Moreover, in the said embodiment, although DST setting was switchable by the user operation in the electronic timepiece 40 and the smart phone 10, either one may be sufficient. In the above embodiment, the DST setting is always changed to AUTO when moving to a different time zone or daylight saving time setting. However, the DST or STD has been changed to the same area in the past. In some cases, it may be set to match the setting.

  In the above embodiment, the smartphone 10 accesses the external data server 90 and acquires the latest daylight saving time implementation information. However, it may be acquired by connecting a portable recording medium or the like, Settings may be updated by operation.

  Moreover, in the said embodiment, although the version information of daylight saving time implementation information was attached | subjected with respect to the whole information, you may set separately for every city. Further, the version information may be determined based on an update date and time instead of a numerical value incremented by one.
