Description

  The present invention relates to a timepiece system and a hand position correction method.

  Conventionally, there are watches that control the position of the hands with a counter and drive the hands. Portable watches have limitations on the number of buttons and display in terms of size, and especially for watches that do not have a pointer position detection mechanism, complicated pointer position correction operations are often required, which impairs usability. there were. For this reason, various techniques for inputting and correcting the pointer position from an external device have been devised (see, for example, Patent Documents 1 and 2). These use a personal computer or a smart phone to correct the pointer position from the outside.

  Conventionally, there are watches that communicate with external devices using wireless communication such as Bluetooth (registered trademark). Some of these watches have a pointer driven in accordance with communication with an external device. However, a portable wristwatch has a problem that the battery is limited in terms of size, and communication and motor driving cannot be performed simultaneously. For this reason, a technique has been devised in which the communication timing is controlled so that the motor drive and communication are not overlapped while the motor is being driven (see, for example, Patent Document 3).

  The portable electronic device 200 is a portable electronic device such as a smartphone, a mobile phone, or a tablet terminal. The portable electronic device 200 includes a control unit 201, an input unit 202, a display unit 203, a storage unit 204, an antenna 205, and a short-range wireless communication unit 206.

  The control unit 201 includes a CPU, and controls each unit included in the portable electronic device 200.

  The antenna 205 is an antenna for the short-range wireless communication unit 206 to communicate. The short-range wireless communication unit 206 communicates with another communication device (for example, the electronic timepiece 100) by short-range wireless communication according to a standard such as Bluetooth.

  Next, the operation in the timepiece system 1 will be described. In the timepiece system 1, the position of the pointer 120 of the electronic timepiece 100 is corrected from the portable electronic device 200 by short-range wireless communication using Bluetooth. FIG. 3 is a diagram for explaining the pointer position correcting method in the present embodiment.

  First, the control unit 201 of the portable electronic device 200 executes an application related to the setting of the electronic timepiece 100 and displays the main menu screen A1 on the display unit 203. On the main menu screen A1, a list of menus related to the setting of the electronic timepiece 100 is displayed so as to be selectable. In the illustrated example, city setting A11, alarm setting A12, and pointer position setting A13 are displayed on the main menu screen A1 as menus. In addition, a transmission button A10 for transmitting information to the electronic timepiece 100 is displayed on the main menu screen A1.

  In order to correct the position of the pointer 120 of the electronic timepiece 100, the user first causes the electronic timepiece 100 to start communication by operating a predetermined button on the electronic timepiece 100. The control unit 101 of the electronic timepiece 100 turns on the power of the wireless communication control unit 111 and transmits an advertisement. Subsequently, the user selects the pointer position setting A13 on the main menu screen A1, and then presses the transmission button A10. The control unit 201 of the portable electronic device 200 starts scanning in the short-range wireless communication unit 206 when the transmission button A10 receives an input while the pointer position setting A13 is selected. Then, when the control unit 201 of the portable electronic device 200 receives the advertisement and establishes a connection with the electronic timepiece 100, the control unit 201 moves to the first mode in which the hand 120 of the electronic timepiece 100 is moved to the temporary hand position corresponding to the reference position. Thus, a pointer position correction start command (pointer position correction information) that is an instruction to move the position of the pointer 120 of the electronic timepiece 100 to the reference position is transmitted from the short-range wireless communication unit 206 to the electronic timepiece 100. In this example, the reference position is set to 00:00:00. Thereafter, the control unit 201 of the portable electronic device 200 displays on the display unit 203 a rough pointer position adjustment screen A2 (first input unit) on which provisional pointer position specifying information for specifying the provisional pointer position is input.

  When receiving the pointer position correction start command from the portable electronic device 200, the control unit 101 of the electronic timepiece 100 moves the pointer 120 while updating the pointer position information of the internal counter so that the position of the pointer 120 becomes the reference position. The reference position movement start process is started. However, when the pointer position information of the internal counter and the actual position of the pointer 120 are shifted, the position of the pointer 120 does not become the reference position. In the illustrated example, the electronic timepiece 100 receives a pointer position correction start command when the pointer 120 is in the state B1 indicating 08:35:20, and the pointer 120 is positioned at the position of the state B2 indicating 09:52:07. Is moving. In the state B2, the pointer position information of the internal counter of the electronic timepiece 100 is the reference position (00 hour 00 minute 00 second), and there is a deviation from the actual position of the pointer 120.

  The user visually confirms the state B2 of the pointer 120 after movement, and inputs it to the rough pointer position adjustment screen A2. On the coarse hand position adjustment screen A2, an input box A21 for inputting the time indicated by the hour hand 120C of the electronic timepiece 100, a minute input box A22 for inputting the minute indicated by the minute hand 120B, and a second for inputting the second indicated by the second hand 120A. An input box A23 and a transmission button A20 for transmitting the input hour, minute and second to the electronic timepiece 100 are displayed.

  In the example shown in the rough hand position adjustment screen A3, 9 is input to the hour input box A21, 52 is input to the minute input box A22, and 7 is input to the second input box A23. When the input of the hour, minute, and second is completed, the user presses the transmission button A20. When the transmission button A20 receives input in the input state shown on the hand position rough adjustment screen A3, the control unit 201 of the portable electronic device 200 enters the second mode in which the hand 120 is moved from the temporary hand position to the rough hand position, A rough hand position adjustment command (provisional hand position specifying information) including the hour, minute, and second input on the rough hand position adjustment screen A3 is transmitted from the short-range wireless communication unit 206 to the electronic timepiece 100. Thereafter, the control unit 201 of the portable electronic device 200 displays on the display unit 203 a pointer position fine adjustment screen A4 (second input unit) on which an instruction to move the position of the pointer 120 can be input.

  When receiving the rough hand position adjustment command, the control unit 101 of the electronic timepiece 100 moves the hand 120 toward the reference position by the difference between the hour / minute / second contained in the received rough hand position adjustment command and the reference position. Start the adjustment process. In the illustrated example, the electronic timepiece 100 receives a rough hand position adjustment command in the state B3 indicating 09:52:07, and moves the pointer 120 to the position of the state B4 indicating 11:59:00. I am letting. In state B4, the pointer position information of the internal counter is the reference position. Further, the position of the pointer 120 in the state B4 is slightly different from the reference position. The reason for this is that when the hour, minute and second are input on the rough hand position adjustment screen A3, the hour hand 120C is not exactly 9:00, but is shifted from 9: 00 ± 1 hour (corresponding to ± 30 ° / 40 steps), and the minute hand 120B. Is not just 52 minutes, but 52 minutes ± 1 minute (corresponding to ± 6 ° / 8 steps), and the second hand 120A is not exactly 7 seconds, but 7 seconds ± 1 second (corresponding to ± 6 ° / 8 steps). Because it is. However, the displacement of the second hand 120A is less than a second digit and is minimal as a time deviation.

  Therefore, the user finely adjusts the position of the pointer 120 of the electronic timepiece 100 on the pointer position fine adjustment screen A4. The pointer position fine adjustment screen A4 includes a still image A41 for teaching the user the reference position, an hour button A42 for selecting the hour hand 120C, a minute button A43 for selecting the minute hand 120B, and a second button A44 for selecting the second hand 120A. A button A45 for returning the pointer 120 one by one, a button A46 for moving the pointer 120 one by one, a button A47 for continuously returning the pointer 120 continuously, and a button A47 for continuously moving the pointer 120 continuously. A button A48 and a confirm button A49 for confirming the position of the set pointer 120 are displayed. The user finely adjusts the position of the pointer 120 by selecting the pointer 120 to be finely adjusted with the buttons A42 to A44 and pressing any one of the buttons A45 to A48.

  The control unit 201 of the portable electronic device 200 enters the third mode in which the coarse adjustment pointer position is finely adjusted. The pointer 120 selected on the pointer position fine adjustment screen A4, the driving direction (return or advance) of the pointer 120, and the continuous Alternatively, a pointer position fine adjustment command that is an instruction to move the position of the pointer 120 including a single drive type is transmitted from the short-range wireless communication unit 206 to the electronic timepiece 100. When receiving the pointer position fine adjustment command, the control unit 101 of the electronic timepiece 100 starts fine adjustment processing for moving the pointer 120 in accordance with the received pointer position fine adjustment command. For example, each time the return button 45 or the forward button 46 is pressed, the control unit 101 of the electronic timepiece 100 drives the stepping motor 122 of the corresponding pointer 120 by one step. Further, the control unit 101 of the electronic timepiece 100 continues to drive the stepping motor 122 of the corresponding pointer 120 while the continuous return button A47 and the continuous advance button A48 are pressed.

  By fine adjustment in this way, the position of the pointer 120 moves to the reference position, and the state B5 is obtained. In the state B5, the pointer position information of the internal counter indicates the reference position and coincides with the position of the pointer 120. When the user visually confirms that the position of the pointer 120 has become the reference position, the user presses the confirmation button A49. When the confirmation button A49 receives an input, the control unit 201 of the portable electronic device 200 ends the pointer position setting and returns the display of the display unit 203 to the main menu screen A1.

  In the illustrated example, the case where the second hand 120A, the minute hand 120B, and the hour hand 120C are corrected has been described. However, the present invention is not limited to this, and the small clock 120D and the date wheel 120E can be similarly corrected. For example, the reference position of the date wheel 120E is one day, and the reference position of the small clock 120D is 0:00 (24:00).

  In the above-described example, the reference position is set to 00:00:00, but the reference position is not limited to this, and may be the current date and time, for example.

  The electronic timepiece 100 has a limited battery in terms of size, and it is difficult to perform communication by the wireless communication control unit 111 and drive of the stepping motor 122 at the same time. The short-range wireless communication unit 1112 and the short-range wireless communication unit 206 perform communication using a periodic communication radio wave, and output a communication radio wave completion signal when the communication timing of the communication radio wave is completed. For this reason, when correcting the position of the pointer 120 of the electronic timepiece 100 as described above, if the communication connection is established between the state B1 and the state B5, the stepping is performed at the communication timing of the periodic communication radio wave. The drive of the motor 122 must be stopped once, and adjustment may take time.

  Therefore, in this embodiment, the electronic timepiece 100 disconnects the communication connection with the portable electronic device 200 during the period from the state B1 to the state B2 and the period from the state B3 to the state B4, and the movement of the pointer 120 is completed. Re-establish communication connection later.

  For example, when the wireless communication control unit 111 receives a pointer position correction start command from the portable electronic device 200 after the wireless communication control unit 111 establishes communication with the portable electronic device 200, the control unit 101 of the electronic timepiece 100 receives the pointer based on the pointer position correction start command. Correct the position. At this time, the control unit 101 disconnects the communication with the portable electronic device 200 after issuing the pointer position correction start command or receiving a subsequent disconnection command, and corrects the pointer position after the communication with the portable electronic device 200 is disconnected. The communication with the portable electronic device 200 is reestablished after the completion of the pointer position correction. The pointer position correction includes an operation of moving the pointer 120 by the stepping motor 122 while updating the internal count to the provisional pointer position corresponding to the reference position. In addition, when the wireless communication control unit 111 receives the rough hand position adjustment command, the control unit 101 disconnects communication with the mobile electronic device 200, and after disconnecting communication with the mobile electronic device 200, the control unit 101 performs rough hand position adjustment command. The pointer 120 is moved to the coarse adjustment pointer position by moving the pointer 120 by the stepping motor 122 while updating the internal counter toward the reference position, and re-establishes communication with the portable electronic device 200 after the movement is completed. Let

  When the wireless communication control unit 111 receives a pointer position fine adjustment command that is an instruction to move the position of the pointer 120, the control unit 101 maintains the communication with the mobile electronic device 200 and maintains the pointer 120 based on the movement instruction. Move. At this time, the control unit 101 permits the stepping motor 122 to be driven only during the movement operation permission period starting from the communication radio wave completion signal emitted from the short-range wireless communication unit 1112. Therefore, the stepping motor 122 moves the pointer 120 during the movement operation permission period.

  Specifically, the electronic timepiece 100 disconnects the communication connection with the portable electronic device 200 by one of the following two methods.

  In the first method, the electronic timepiece 100 automatically disconnects communication.

When the transmission / reception of data is completed, the short-range wireless communication unit 1112 generates a communication radio wave completion signal indicating that the data transmission / reception is completed, and outputs the generated communication radio wave completion signal to the control unit 101. The hand movement driving permission period is a period during which the stepping motor 122 permits the driving of the pointer 120. The stepping motor 122 moves the pointer 120 during the movement operation permission period.

  FIG. 10 is a timing chart showing an operation during the fine adjustment processing of the electronic timepiece 100 in the present embodiment. This figure shows an operation example when fine adjustment processing is performed in a connection state where communication connection between the electronic timepiece 100 and the portable electronic device 200 is established. In this figure, the code | symbol g1 represents the state in which the wireless communication control part 111 is transmitting / receiving data. Symbol g2 represents the timing at which the communication control unit 1013 receives the communication radio wave completion signal output from the wireless communication control unit 111. Moreover, T2 represents the hand movement drive permission period set from the timing at which the communication radio wave completion signal is received. Reference numeral g4 represents the timing at which the pointer control unit 1016 outputs a drive pulse to the stepping motor 122, that is, the timing at which the needle is actually moved.

  For example, when the pointer position fine adjustment command is included in the sampling radio wave g1 at t16, the control unit 101 delays some processing and then performs t18 within the hand movement drive permission period T2 set from t17 as the starting point. Is used as a timing for moving the needle, a drive pulse is generated, and the generated drive pulse is output to the stepping motor 122. Any processing delay is affected by the load of simultaneous processing, the number of loads, and the like.

  On the other hand, when the control unit 101 attempts to process the indication of the pointer position fine adjustment command received by the sampling radio wave g1 at t16 during a period from t19 to t20 outside the hand movement drive permission period T2 due to some processing delay. Then, it waits until the next hand movement drive permission period T2, uses t22 to t23 in the next hand movement drive permission period T2 as the hand movement timing, generates a drive pulse, and outputs the generated drive pulse to the stepping motor 122.

  That is, the control unit 101 sets only the movement operation permission period T2 as the operation timing. Therefore, the control unit 101 moves the pointer 120 only during the movement operation permission period T2, and does not move the pointer 120 outside the movement operation permission period T2.

  Note that the control unit 101 does not generate a driving pulse as indicated by t25 to t26 when the sampling position g1 during communication does not include the pointer position fine adjustment command.

  As described above, the correction of the pointer position in the fine adjustment process is performed in a connection state (a state in which communication connection is maintained) between the electronic timepiece 100 and the portable electronic device 200.

  As described above, the timepiece system 1 according to the present embodiment includes the portable electronic device 200 and the electronic timepiece 100 that can communicate with the portable electronic device 200. When the electronic timepiece 100 receives the pointer position correction information from the portable electronic device 200 after the short-range wireless communication unit 1112 that communicates with the portable electronic device 200 and the short-range wireless communication unit 1112 establishes communication with the portable electronic device 200. , And a control unit 101 that corrects the pointer position based on the pointer position correction information. The electronic timepiece 100 and the portable electronic device 200 are disconnected from each other after the electronic timepiece 100 receives the pointer position correction information. Further, the control unit 101 starts the hand position correction after the communication with the mobile electronic device 200 is disconnected, and reestablishes the communication with the mobile electronic device 200 after the completion of the hand position correction.

  As a result, the electronic timepiece 100 does not need to communicate during driving of the stepping motor 122 for correcting the hand position, and can efficiently correct the position of the hand 120.

  The hand position correction includes an operation of moving the hand 120 by the stepping motor 122 while updating the internal counter to the provisional hand position corresponding to the reference value, and the mobile electronic device 200 communicates with the electronic timepiece 100 via a short-range wireless communication. After the communication unit 206, the input unit 202 to which provisional pointer position specifying information for specifying the provisional pointer position is input, and the short-range wireless communication unit 206 reestablish communication with the electronic timepiece 100, the provisional pointer position specifying information is obtained. And a control unit 201 that transmits to the electronic timepiece 100. The electronic timepiece 100 and the portable electronic device 200 disconnect communication after the electronic timepiece 100 receives the provisional pointer position specifying information, and the control unit 101 receives the provisional pointer received after the communication with the portable electronic device 200 is disconnected. The pointer 120 is moved to the coarse adjustment pointer position by moving the pointer 120 by the stepping motor 122 while updating the internal counter toward the reference value based on the position specifying information, and communicates with the portable electronic device 200 after the movement is completed. Is reestablished.

  As a result, the electronic timepiece 100 does not need to communicate during the driving of the stepping motor 122 for coarse adjustment that moves the hands 120 from the temporary hand position to the coarse hand position, and efficiently corrects the position of the hands 120. can do.

  In addition, the mobile electronic device 200 includes an input unit 202 that can input an instruction to move the position of the pointer 120. In addition, the control unit 101 moves the pointer 120 based on the movement instruction input to the input unit 202. Thereby, the pointer 120 at the coarse adjustment pointer position can be finely adjusted.

  The short-range wireless communication unit 1112 performs communication using a periodic communication radio wave, and outputs a communication radio wave completion signal when the communication timing of the communication radio wave is completed. The control unit 101 starts the communication radio wave completion signal. The stepping motor 122 is allowed to be driven only during the movement operation permission period, and the stepping motor 122 moves the pointer 120 during the movement operation permission period. Thereby, in the electronic timepiece 100, it is possible to prevent the communication timing and the driving timing of the stepping motor 122 from overlapping during fine adjustment.

  Note that all or some of the functions of each unit included in the electronic timepiece 100 or the portable electronic device 200 in the above-described embodiment are recorded on a computer-readable recording medium and a program for realizing these functions.

  For example, in the above-described embodiment, the electronic timepiece 100 has disconnected the communication connection with the portable electronic device 200 by turning off the power of the wireless communication control unit 111, but is not limited thereto, and the communication is stopped. The communication connection with the portable electronic device 200 may be disconnected.

  In the above-described embodiment, the coarse adjustment process for moving the pointer 120 from the temporary pointer position to the coarse adjustment pointer position is performed only once. However, the present invention is not limited to this, and may be performed twice or more. For example, the mobile electronic device 200 may return from the pointer position fine adjustment screen to the pointer position rough adjustment screen.

  In the above-described embodiment, the mobile electronic device 200 inputs temporary hand position specifying information for specifying the hand position of the hand 120 on the hand position rough adjustment screen. However, the present invention is not limited to this. The provisional hand position specifying information may be input by displaying an illustration and moving the position of the hand of the displayed clock on the touch panel. Alternatively, provisional hand position specifying information may be input by imaging the electronic timepiece 100 with a camera and analyzing the position of the hand 120.

  In the above-described embodiment, the case where each pointer 120 moves independently by driving the corresponding stepping motor 122 has been described. However, the present invention is not limited to this, and a plurality of pointers 120 are driven by one stepping motor 122. It may move in conjunction. For example, the second hand 120A may move independently, and the minute hand 120B and the hour hand 120C may move in conjunction with each other. Alternatively, the hour hand 120C may move independently, and the minute hand 120B and the second hand 120A may move in conjunction with each other. Moreover, the hour hand 120C and the date wheel 120E may move in conjunction with each other.
