Description

The present invention relates to a clock system and a pointer position correction method.

Conventionally, there is a clock that controls the position of the pointer with a counter and drives the pointer. Portable watches have a limit on the number of buttons and display due to their size, and especially for watches that do not have a pointer position detection mechanism, complicated pointer position correction operations are often required, which causes problems such as impairing usability. there were. Therefore, 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 utilize personal computers and smartphones to correct the pointer position from the outside.

Further, conventionally, there is a clock that communicates with an external device by using wireless communication such as Bluetooth (registered trademark). Some of these watches drive pointers in response to communication with external devices. However, there is a problem that a portable wristwatch or the like has a limitation on a battery in terms of size, and communication and driving of a motor cannot be performed at the same time. Therefore, a technique has been devised in which the communication timing is controlled during the motor drive so that the motor drive and the communication do not overlap (see, for example, Patent Document 3).

However, in Bluetooth communication, it is necessary to perform communication at predetermined time intervals in order to maintain the connection, so even if the communication timing is adjusted, there is a limit to the time width that can be adjusted. In addition, depending on the pointer of the clock (for example, a date wheel), it may take a long time to drive to the reference position. Therefore, in the techniques described in Patent Documents 1 to 3, when the position of the pointer that takes a long time to drive is corrected by using the communication by Bluetooth, the drive of the motor is stopped in order to maintain the connection on the way. There is a problem that the necessity arises, and as a result, the adjustment takes time.

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 clock 100) by short-range wireless communication according to a standard such as Bluetooth.

Next, the operation in the clock system 1 will be described. In the clock system 1, the position of the pointer 120 of the electronic clock 100 is corrected from the portable electronic device 200 by short-range wireless communication using Bluetooth. FIG. 3 is a diagram for explaining a guideline position correction 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 clock 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 clock 100 is displayed so as to be selectable. In the illustrated example, the city setting A11, the alarm setting A12, and the pointer position setting A13 are displayed on the main menu screen A1 as menus. Further, on the main menu screen A1, a transmission button A10 for transmitting information to the electronic clock 100 is displayed.

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

When the control unit 101 of the electronic clock 100 receives the pointer position correction start command from the portable electronic device 200, the control unit 101 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, if the pointer position information of the internal counter and the actual position of the pointer 120 deviate from each other, the position of the pointer 120 does not become the reference position. In the illustrated example, the electronic clock 100 receives the pointer position correction start command when the pointer 120 is in the state B1 pointing to 08:35:20, and the pointer 120 is in the position B2 pointing to 09:52:07. Is moving. In the state B2, the pointer position information of the internal counter of the electronic clock 100 is the reference position (00:00:00), which is different 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 pointer position rough adjustment screen A2. On the pointer position coarse adjustment screen A2, an hour input box A21 for inputting the hour indicated by the hour hand 120C of the electronic clock 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 are displayed. The input box A23 and the transmission button A20 for transmitting the input hour, minute, and second to the electronic clock 100 are displayed.

In the example shown in the pointer position coarse 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 send button A20. When the transmission button A20 receives an input in the input state shown in the pointer position coarse adjustment screen A3, the control unit 201 of the portable electronic device 200 enters the second mode of moving the pointer 120 from the provisional pointer position to the coarse pointer position. A pointer position coarse adjustment command (provisional pointer position identification information) including hours, minutes, and seconds input to the pointer position coarse adjustment screen A3 is transmitted from the short-range wireless communication unit 206 to the electronic clock 100. After that, the control unit 201 of the portable electronic device 200 displays the pointer position fine adjustment screen A4 (second input unit) capable of inputting the movement instruction of the position of the pointer 120 on the display unit 203.

When the control unit 101 of the electronic clock 100 receives the pointer position coarse adjustment command, the control unit 101 moves the pointer 120 toward the reference position by the difference between the hour, minute, and second included in the received pointer position coarse adjustment command and the reference position. The adjustment process is started. In the illustrated example, the electronic clock 100 receives the pointer position coarse adjustment command in the state B3 pointing to 09:52:07, and moves the pointer 120 to the position in the state B4 pointing to 11:59:00. I'm letting you. In the 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 is that when the hour, minute, and second are input on the pointer position coarse adjustment screen A3, the hour hand 120C is not exactly 9 o'clock, but is shifted by 9 o'clock ± 1 hour (equivalent to ± 30 ° / 40 steps), and the minute hand 120B Is not exactly 52 minutes, but is off by 52 minutes ± 1 minute (equivalent to ± 6 ° / 8 steps), and the second hand 120A is also off by 7 seconds ± 1 second (equivalent to ± 6 ° / 8 steps), not just 7 seconds. Because it is. However, the deviation of the second hand 120A is less than a second digit, which is the minimum time deviation.

Therefore, the user finely adjusts the position of the pointer 120 of the electronic clock 100 on the pointer position fine adjustment screen A4. On the pointer position fine adjustment screen A4, a still image A41 for teaching the reference position to the user, 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 are displayed. The return button A45 that returns the pointer 120 one by one, the forward button A46 that advances the pointer 120 one by one, the continuous return button A47 that continuously returns the pointer 120, and the continuous advance button 120 that advances the pointer 120 continuously. A button A48 and a confirmation button A49 for confirming the position of the set pointer 120 are displayed. The user selects the pointer 120 to be finely adjusted with the buttons A42 to A44, and presses any of the buttons A45 to A48 to finely adjust the position of the pointer 120.

The control unit 201 of the portable electronic device 200 is in the third mode for finely adjusting the coarse adjustment pointer position, and is continuous with the pointer 120 selected on the pointer position fine adjustment screen A4 and the driving direction (back or forward) of the pointer 120. Alternatively, a pointer position fine adjustment command, which 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 clock 100. When the control unit 101 of the electronic clock 100 receives the pointer position fine adjustment command, the control unit 101 starts the fine adjustment process of moving the pointer 120 according to the received pointer position fine adjustment command. For example, the control unit 101 of the electronic clock 100 drives the stepping motor 122 of the corresponding pointer 120 for one step each time the back button 45 or the forward button 46 is pressed. Further, the control unit 101 of the electronic clock 100 continues to drive the stepping motor 122 of the corresponding pointer 120 while the continuous return button A47 and the continuous forward button A48 are pressed.

By making fine adjustments in this way, the position of the pointer 120 moves to the reference position, and the state B5 is reached. 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 reached the reference position, the user presses the confirmation button A49. When the confirmation button A49 receives the 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 modified has been described, but the present invention is not limited to this, and the small clock 120D and the date wheel 120E can be modified in the same manner. For example, the reference position of the date wheel 120E is one day, and the reference position of the small clock 120D is 00:00 (24:00).

Further, 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, for example, the current date and time.

The battery of the electronic clock 100 is limited in terms of size, and it is difficult for the wireless communication control unit 111 to perform communication and drive the stepping motor 122 at the same time. The short-range wireless communication unit 1112 and the short-range wireless communication unit 206 communicate with each other by periodic communication radio waves, and output a communication radio wave completion signal when the communication timing of the communication radio waves is completed. Therefore, when the position of the pointer 120 of the electronic clock 100 is corrected as described above, if the communication connection is left established between the states B1 and the state B5, stepping is performed at the communication timing of the periodic communication radio wave. The drive of the motor 122 must be temporarily stopped, and the adjustment may take time.

Therefore, in the present embodiment, the electronic watch 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. Later reestablish the communication connection.

For example, when the control unit 101 of the electronic watch 100 receives the 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 gives a 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 receiving the command to start the pointer position correction or after receiving the disconnection command thereafter, and corrects the pointer position after the communication with the portable electronic device 200 is disconnected. Is started, and communication with the portable electronic device 200 is reestablished after the pointer position correction is completed. 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. Further, when the wireless communication control unit 111 receives the pointer position coarse adjustment command, the control unit 101 disconnects the communication with the portable electronic device 200, and after the communication with the portable electronic device 200 is disconnected, the pointer position coarse adjustment command By moving the pointer 120 by the stepping motor 122 while updating the internal counter toward the reference position based on the above, the pointer 120 is moved to the coarse adjustment pointer position, and communication with the portable electronic device 200 is reestablished after the movement is completed. Let me.

Further, when the wireless communication control unit 111 receives the pointer position fine adjustment command which is an instruction to move the position of the pointer 120, the control unit 101 maintains the communication with the portable electronic device 200 and the pointer 120 is based on the movement instruction. To move. At this time, the control unit 101 permits the stepping motor 122 to be driven only during the hand movement 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 hand movement permission period.

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

In the first method, the electronic clock 100 automatically disconnects the communication connection.

Here, the control unit 101 of the electronic clock 100 permits the stepping motor 122 to be driven only during the hand movement permission period starting from the communication radio wave completion signal emitted from the short-range wireless communication unit 1112 during the fine adjustment processing. .. When the data transmission / reception 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 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 hand movement permission period.

FIG. 10 is a timing chart showing the operation of the electronic clock 100 during the fine adjustment processing in the present embodiment. This figure shows an operation example in which fine adjustment processing is performed in a connected state in which a communication connection between the electronic watch 100 and the portable electronic device 200 is established. In this figure, reference numeral g1 represents a state in which the wireless communication control unit 111 transmits / receives data. Reference numeral g2 represents a timing at which the communication control unit 1013 receives the communication radio wave completion signal output by the wireless communication control unit 111. Further, T2 represents a hand movement permission period set from the timing of receiving the communication radio wave completion signal. Reference numeral g4 represents a timing at which the pointer control unit 1016 outputs a drive pulse to the stepping motor 122, that is, a hand movement timing at which the hand movement is actually performed.

For example, when the sampling radio wave g1 at t16 includes the pointer position fine adjustment command, the control unit 101 delays some processing and then t18 within the hand movement permission period T2 set starting from t17. Is set as the hand movement timing, a drive pulse is generated, and the generated drive pulse is output to the stepping motor 122. It should be noted that some 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 intends to process the instruction of the pointer position fine adjustment command received by the sampled radio wave g1 at t16 in the period from t19 to t20 outside the hand movement permission period T2 due to some processing delay. , It waits until the next hand movement permission period T2, sets 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 hand movement permission period T2 as the hand movement timing. Therefore, the control unit 101 moves the pointer 120 only during the hand movement permission period T2, and does not move the pointer 120 except during the hand movement permission period T2.

Note that the control unit 101 does not generate a drive pulse as shown in t25 to t26 when the sampling radio wave 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 processing is performed in the connected state (the state in which the communication connection is maintained) between the electronic watch 100 and the portable electronic device 200.

As described above, the clock system 1 in the present embodiment includes a portable electronic device 200 and an electronic clock 100 capable of communicating with the portable electronic device 200. When the electronic clock 100 receives the pointer position correction information from the portable electronic device 200 after the short-range wireless communication unit 1112 communicating with the portable electronic device 200 and the short-range wireless communication unit 1112 establishes communication with the portable electronic device 200. A control unit 101 that corrects the pointer position based on the pointer position correction information. The electronic clock 100 and the portable electronic device 200 disconnect from each other after the electronic clock 100 receives the pointer position correction information. Further, the control unit 101 starts the pointer position correction after the communication with the portable electronic device 200 is disconnected, and reestablishes the communication with the portable electronic device 200 after the completion of the pointer position correction.

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

Further, the pointer position correction includes an operation of moving the pointer 120 by the stepping motor 122 while updating the internal counter to the provisional pointer position corresponding to the reference value, and the portable electronic device 200 is a short-range radio that communicates with the electronic watch 100. After the communication unit 206, the input unit 202 into which the provisional pointer position identification information for specifying the provisional pointer position is input, and the short-range wireless communication unit 206 reestablish communication with the electronic clock 100, the provisional pointer position identification information is input. A control unit 201 for transmitting to the electronic clock 100 is provided. The electronic clock 100 and the portable electronic device 200 disconnect from each other after the electronic clock 100 receives the provisional pointer position identification information, and the control unit 101 receives the provisional pointer after the communication with the portable electronic device 200 is disconnected. The pointer 120 is moved to the coarse 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 identification information, and communication with the portable electronic device 200 is completed after the movement is completed. Is characterized by reestablishing.

As a result, the electronic clock 100 does not need to communicate while driving the stepping motor 122 for rough adjustment for moving the pointer 120 from the provisional pointer position to the coarse adjustment pointer position, and efficiently corrects the position of the pointer 120. can do.

Further, the portable electronic device 200 includes an input unit 202 capable of inputting a movement instruction of the position of the pointer 120. Further, the control unit 101 moves the pointer 120 based on the movement instruction input to the input unit 202. As a result, the pointer 120 at the coarse adjustment pointer position can be finely adjusted.

Further, the short-range wireless communication unit 1112 communicates by periodic communication radio waves, outputs a communication radio wave completion signal when the communication timing of the communication radio waves is completed, and the control unit 101 starts from the communication radio wave completion signal. The stepping motor 122 is allowed to be driven only during the hand movement permission period, and the stepping motor 122 moves the pointer 120 during the hand movement permission period. As a result, in the electronic clock 100, it is possible to prevent the communication timing and the drive timing of the stepping motor 122 from overlapping during the fine adjustment.

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

Further, in the above-described embodiment, the portable electronic device 200 inputs the provisional pointer position specifying information for specifying the provisional pointer position of the pointer 120 on the pointer position coarse adjustment screen, but the present invention is not limited to this, and for example, the watch. The provisional pointer position identification information may be input by displaying the illustration and moving the position of the displayed pointer of the clock by the touch panel. Alternatively, the provisional pointer position identification information may be input by photographing the electronic clock 100 with a camera and analyzing the position of the pointer 120.

Further, in the above-described embodiment, the case where each pointer 120 moves independently by driving the corresponding individual stepping motor 122 has been described, but 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 tandem. 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. Further, the hour hand 120C and the date wheel 120E may move in conjunction with each other.
