Description

  The present invention relates to an electronic timepiece and a speed measurement management system.

  2. Description of the Related Art Conventionally, in an electronic timepiece, there is a technique for connecting to an external electronic device using near field communication such as Bluetooth (registered trademark), receiving information set and managed by the electronic device, and determining the operation of the electronic timepiece. is there. Patent Document 1 discloses a technique for easily acquiring accurate time information and correcting the time of an electronic timepiece by connecting the electronic timepiece to a mobile phone.

  On the other hand, there is a technique for managing data by transferring data acquired by various measurement sensors to a computer via a wired or wireless communication line. In Patent Document 2, a predetermined amount related to a traveling operation of a bicycle is acquired by a sensor attached to a bicycle body, and the predetermined amount data acquired by transferring to a portable computer by communication is stored, managed, and used. Technology is disclosed.

  Some electronic watches have been equipped with various sensors that measure temperature, atmospheric pressure, acceleration, and geomagnetic field, and a time measurement function that can measure, calculate, and display various physical quantities and elapsed time. . In particular, a wearable portable electronic watch such as an electronic wristwatch has portability regardless of the situation, and easily obtains various measurement data through simple operations, Data calculated using the data can be displayed on the display screen. Such measurement data and calculation data are often different in the number of digits and display range from the time and date and time, and conventionally, a digital display screen that facilitates various displays has been preferably used.

  On the other hand, an analog electronic timepiece has limitations on the amount of information that can be displayed and the type of information that can be displayed, and the settings and operations are complicated and difficult to understand. One of the numerical data that is difficult to display with an analog electronic timepiece is speed data. The velocity value is obtained by the magnitude of the displacement amount such as the moving distance with respect to the measured time. Since this amount of displacement varies significantly depending on the object to be measured and its displacement method, it is very complicated to input and set the amount of displacement in an analog electronic timepiece. Therefore, conventionally, in an analog type electronic timepiece, a time required for a displacement of a unit amount (for example, a distance of 1 km) is measured and displayed as it is with a pointer, and the measured value is used as an average speed (unit average speed) for the unit amount. A tachymeter whose value for conversion is written on a bezel or dial is used.

JP 2009-118403 A JP 2007-99034 A

  However, in the analog electronic timepiece, the speed measurement and display according to the prior art is not flexible in the amount of displacement, and if the amount of displacement to be measured is different from the unit amount, the displayed unit average speed is more actual. There is a problem that it is difficult to read the speed because it is necessary to convert to the average speed. Further, in the tachymeter, there is a problem that it is difficult to read the value between them because the display interval of the speed is not uniform. Therefore, in the electronic timepiece, there is a problem that even if various elapsed times are measured through simple operations of the user according to the situation in various scenes, these cannot be sufficiently utilized as data relating to speed. is there.

  An object of the present invention is to provide an electronic timepiece and a speed measurement management system capable of calculating and displaying a speed based on a measured elapsed time more easily and easily.

FIG. 3 is a block diagram showing the internal configuration of the analog electronic timepiece 40.
The analog electronic timepiece 40 includes a CPU 41 (Central Processing Unit) (speed calculation means, speed display control means, data output means, elapsed time display control means), ROM 42 (Read Only Memory), RAM 43 (Random Access Memory), Oscillation circuit 44, frequency divider circuit 45, timing circuit 46, operation unit 47 (operation unit), Bluetooth module 48 (communication unit), UART 49 (Universal Asynchronous Receiver / Transmitter) and antenna AN4, and power supply unit 50 The driving circuit 51, the illumination unit 52 and its driver 53, the buzzer unit 54 and its driver 55, the bus 56, the second hand 61, the minute hand 62, the hour hand 63, the date wheel 64, the speed indicator 65, and the function long hand 66 described above. , Functional short needle 67 and functional auxiliary needle 68, wheel train mechanisms 71-74, stepping motors 81-84, and the like.

  The CPU 41 performs various arithmetic processes and controls the overall operation of the analog electronic timepiece 40. The CPU 41 loads the control program read from the ROM 42 to the RAM 43 and performs processing related to various operations such as time display operation, stopwatch timing, and display operation.

  The ROM 42 is a mask ROM, a rewritable nonvolatile memory, or the like, and stores a control program and initial setting data stored in advance. The control program includes a connection control program 421 related to Bluetooth communication, such as establishment and maintenance of communication connection, processing for releasing the connection when communication connection continues without data transmission / reception, etc. Is done.

  The RAM 43 is a volatile memory such as SRAM or DRAM, and provides a working memory space to the CPU 41 to store temporary data and various setting data. The RAM 43 includes a measurement time storage unit 431 that stores the measurement time measured by the stopwatch function, and a distance setting storage unit 432 that stores a distance for calculating a speed from the measurement time.

  The oscillation circuit 44 generates and outputs a predetermined frequency signal determined in advance. For example, a crystal oscillator is used for the oscillation circuit 44.

  The frequency dividing circuit 45 divides the frequency signal input from the oscillation circuit 44 into a frequency signal used by the time measuring circuit 46 and the CPU 41 and outputs the frequency signal. The frequency of the output signal may be changeable based on the setting by the CPU 41. Further, the frequency of the oscillation circuit 44 may be output as it is. The CPU 41 counts signals output from the frequency dividing circuit 45, thereby realizing a stopwatch function and a timer function. Further, the CPU 41 and the frequency dividing circuit 45 constitute time measuring means.

  The timer circuit 46 counts the current date and time by counting the number of input signals and adding it to the initial value.

  The operation unit 47 receives an input operation from the user and outputs an electrical signal corresponding to the input operation to the CPU 41 via the bus 56 as an input signal. The operation unit 47 includes the above-described push button switches B1 to B4 and the crown switch C1.

  The Bluetooth module 48 is a control module for performing Bluetooth communication with an external electronic device via the antenna AN4. Transmission data sent from the CPU 41 via the bus 56 is subjected to processing such as serial / parallel conversion by the UART 49, modulated by the Bluetooth module 48, and transmitted to an external device. Also, the received data received by the Bluetooth module 48 via the antenna AN4 is demodulated and then subjected to processing such as serial / parallel conversion by the UART 49 and output to the CPU 41 via the bus 56. The operation of the Bluetooth module 48 is uniquely controlled by the CPU 41.

  The power supply unit 50 supplies power related to the operation of the analog electronic timepiece 40 at a predetermined voltage. Here, a solar battery and a secondary battery are used for the power supply unit 50. An electromotive force is generated in a solar panel (not shown) by light incident on the exposed surface of the dial 3 and is supplied to the CPU 41, the Bluetooth module 48, and the like, and when surplus power is generated, it is stored in the secondary battery. The When the amount of light incident on the solar panel is insufficient, power is supplied from the secondary battery. The power supply by the solar battery and the secondary battery is sufficient for normal time display to be maintained for a long time (for example, yearly), but more than necessary for the operation with high power consumption such as the Bluetooth module 48. It is desirable not to be used for a long time.

  The drive circuit 51 outputs a drive pulse having a predetermined voltage to the stepping motors 81 to 84 in accordance with a control signal input from the CPU 41 via the bus. The drive circuit 51 can change the length (pulse width) of the drive pulse according to the state of the analog electronic timepiece 40. In addition, when a control signal for simultaneously driving a plurality of hands is input, the output timing of the drive pulse can be slightly shifted in order to reduce the load peak.

  The illumination unit 52 includes, for example, an LED (Light Emitting Diode), and illuminates the exposed surface and the pointer of the dial 3 by turning on the LED by a drive voltage signal input from the driver 53.

  The buzzer unit 54 includes, for example, a piezoelectric element, and generates a beep sound when the piezoelectric element vibrates in response to a predetermined drive voltage signal supplied from the driver 55 and outputs an audio frequency signal.

  The stepping motor 81 rotates the second hand 61 via a gear train mechanism 71 that is an array of a plurality of gears. The stepping motor 82 rotates the minute hand 62 and the hour hand 63 in conjunction with each other via the train wheel mechanism 72. The stepping motor 83 rotates the date wheel 64 and the speed indicator 65 in conjunction with each other via the wheel train mechanism 73. The stepping motor 84 rotates the functional long hand 66, the functional short hand 67, and the functional auxiliary needle 68 in conjunction with each other via the wheel train mechanism 74.

  How many times each pointer rotates each time the stepping motors 81 to 84 are driven once is determined by the arrangement of gears in the gear train mechanisms 71 to 74, respectively. For example, here, the train wheel mechanisms 71 and 74 are configured such that the second hand 61 and the function long hand 66 are rotated 6 degrees each time the stepping motors 81 and 84 are driven once, respectively, and the minute hand 62 and the speed indicator 65 are configured. The train wheel mechanisms 72 and 73 are configured to rotate once every time the stepping motors 82 and 83 are driven once.

  The hour hand 63 rotates at a rotation angle of 1/12 with respect to the rotation of the minute hand 62. Accordingly, when the minute hand 62 is rotated once every 10 seconds to make one turn on the dial 3 in 60 minutes, the hour hand 63 rotates on the dial 3 by 30 degrees. The hour hand 63 makes one turn on the dial 3 while the minute hand 62 makes 12 turns in 12 hours.

  In the date indicator 64, the date indicator indicating the date on the date indicator 64 is rotated by one day while the speed indicator 65 makes 12 turns in the small window 5. Therefore, the date indicator 64 makes one turn when the speed indicator 65 makes 372 turns in the small window 5. That is, even if the speed indicator 65 rotates back and forth within a range of one turn or less, the date mark exposed from the opening 4 continues to be exposed with almost no deviation.

  The functional short hand 67 rotates at a rotation angle of 1/12 with respect to the rotation of the functional long hand 66. Therefore, the functional long hand 66 rotates 6 degrees every minute to make one round in the small window 6 in 60 minutes, while the functional short hand 67 rotates in the small window 6 by 30 degrees. And while the function long hand 66 makes 12 rounds in 12 hours, the function short hand 67 makes a round in the small window 6.

  The function auxiliary needle 68 rotates at a rotation angle of 1/24 with respect to the rotation of the function long hand 66. Therefore, while the function long hand 66 makes a round in the small window 6, the function secondary needle 68 rotates 15 degrees in the small window 7, and while the function long hand 66 makes 24 turns in the small window 6, the function secondary needle 68. 68 goes around in the small window 7.

  The time hands 61 to 63, the date indicator 64, the speed hands 65, and the function hands 66 to 68 are not particularly limited, but the forward rotation direction (the direction in which the time advances, clockwise when viewed from the exposed surface side of the dial 3). Can be rotated at 90 pps (pulse per second), and can be rotated at 32 pps in the reverse direction.

The CPU 11 reads out and executes the clock management application 141 to perform settings related to various operations of the analog electronic timepiece 40, or to acquire, manage, edit, and use data measured by the analog electronic timepiece 40. I can do it. The stopwatch data management unit 142 stores various setting data set in the analog electronic timepiece 40 by the clock management application 141 and data obtained and measured by the analog electronic timepiece 40.

  The built-in clock 15 is a counter that counts and holds the current time. In the smartphone 10, the current time is read and displayed on the display unit 16. Further, the present time data and the set time data related to various functions are compared, and various operations are performed. 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 base station by the RF transceiver circuit 22.

  The display unit 16 includes, for example, an LCD (liquid crystal display). A driver 17 (liquid crystal driver) that operates in response to a control signal sent from the CPU 11 drives the LCD to display various functions of the smartphone 10. The display unit 16 may include a display screen of another display method, for example, an organic ELD (Electro-Luminescent Display), and the driver 17 is appropriately selected according to the display method of the display screen.

  The operation unit 18 includes a touch sensor, detects a user's touch operation position and operation content on the LCD screen of the display unit 16, generates an electric signal corresponding to the operation, and outputs the electric signal to the CPU 11 as an input signal. . The operation unit 18 may further include one or a plurality of operation keys and switches, and may output an input signal to the CPU 11 based on an operation performed by the user on the operation keys and switches.

  The speaker 19 converts an electrical signal into an audio signal based on a signal from the codec 21 and outputs audio. The microphone 20 detects sound waves, converts them into electric signals, and outputs them to the codec 21. The codec 21 decodes the encoded and compressed digital audio signal and sends it as an analog signal to the speaker 19, and encodes the audio signal acquired from the microphone 20 and outputs it to the CPU 11 and the communication circuit 23. In addition, it is good also as providing separately the speaker for telephone calls, and the speaker for outputting other alerting sound etc. outside.

  The vibration motor 27 is for informing the user by generating vibration. When a control signal is sent from the CPU 11 to the driver 28, the driver 28 converts it into a voltage signal necessary for operating the vibration motor 27 and outputs it. As the vibration motor 27, for example, a rotary motor is used.

For example, a rechargeable lithium ion battery is used as the power source of the smartphone 10.
The RF transmission / reception circuit 22 and the Bluetooth module 24 and the call GPS reception processing unit 26 can be individually controlled to turn on / off the power supply separately from the power operation of the entire smartphone 10.

Next, the speed measurement operation in the speed measurement management system 1 of the present embodiment will be described.
In the speed measurement management system 1, a unit distance (set value) is set in the smartphone 10, and the unit distance is transferred to the analog electronic timepiece 40. In the analog electronic timepiece 40, the average speed is calculated based on the unit distance and the measurement time and displayed.

  FIG. 5 is a plan view showing a unit distance setting screen in the smartphone 10.

  When the clock management application 141 is executed on the smartphone 10 and the stopwatch management program is started, a menu is displayed, and a menu “Distance” for setting a unit distance and a menu “Data Book” for reading measurement data can be selected. It becomes. Here, the unit distance setting menu “Distance” 16a is selected, and the unit distance setting screen is displayed.

  In this unit distance setting screen, an input box 16b for directly inputting a unit distance and a unit distance setting list 16c for selecting from among already set are displayed. A numerical value is input to the input box 16b and the set button 16d is tapped (or a preset selection operation such as touch), or a line in which the distance to be selected is indicated from the unit distance setting list 16c is tapped. The distance to be set is selected by the operation.

  FIG. 6 is a flowchart showing a control procedure by the CPU 11 of the unit distance setting process in the smartphone 10.

This unit distance setting process is started in response to selection of the menu “Distance” 16a for setting the unit distance.
When the unit distance setting process is started, the CPU 11 requests the analog electronic timepiece 40 to establish communication via Bluetooth and establishes a communication connection (step S101). Then, the CPU 11 waits for a distance input from the user or a selection input from the distance displayed in the list, and determines whether or not there is an input (step S102). If it is determined that there is no direct input or selection input (“NO” in step S102), the CPU 11 repeats the process of step S102 and continues to wait for input.

  When it is determined that there is a direct input or a selection input (“YES” in step S102), the CPU 11 acquires the input distance and sets it as a unit process in the analog electronic timepiece 40 (step S103). .

  The CPU 41 further determines whether or not a transmission input from the user to the analog electronic timepiece 40 has been received (step S104). If there is a transmission request (“YES” in step S104), the CPU 11 transmits the set unit distance to the analog electronic timepiece 40 (step S105). Then, the process of the CPU 11 proceeds to step S106. If it is determined that there is no transmission request (“NO” in step S104), the processing of the CPU 11 proceeds to step S106 as it is.

The CPU 11 cancels the Bluetooth communication connection with the analog electronic timepiece 40 (step S106). Then, the CPU 11 ends the unit distance setting process.
Note that the communication connection with the analog electronic timepiece 40 related to the processing of steps S101 and S106 may be performed only at the timing of actually transmitting data transmission, not at the beginning and end of the unit distance setting processing. Further, the processing in step S101 may be performed by receiving a communication connection request by Bluetooth from the analog electronic timepiece 40 and performing communication connection. Further, the communication connection may be released automatically without specifying the timing as described above and when there is no data transmission / reception for a predetermined time, for example, 3 minutes. Further, when the unit distance is set in the process of step S103 and the communication connection is established, the unit distance is automatically transmitted to the analog electronic timepiece 40 without interposing the process of step S104. Also good.

In the analog electronic timepiece 40, when measurement by a stopwatch is performed with the unit distance set, the measurement time is displayed in real time by the function hands 66 to 68 and the second hand 61, and a lap time (period value), etc. Each time the elapsed time corresponding to the unit distance is obtained, the average speed of the period (a plurality of periods) is calculated based on the unit distance, and the calculated average speed is displayed in the small window 5 by the speed pointer 65. Let
That is, the function hands 66 to 68 and the second hand 61 constitute a time hand.

  Here, when going around the same course, it is possible to acquire the lap time of each round by setting one unit distance, but pass through checkpoints with different distance intervals in road races etc. In such a case, it is possible to set a unit distance by adding an order to a plurality of section distances.

FIG. 7 is a flowchart showing a control procedure by the CPU 41 of stopwatch processing executed by the analog electronic timepiece 40.
This stopwatch process is started when a stopwatch mode is called by the user and a measurement start operation is performed.

  When the stopwatch process is started, the CPU 41 first starts measuring elapsed time and outputs a control signal to the drive circuit 51 to cause the function hands 66 to 68 and the second hand 61 to start displaying the elapsed time. (Step S401). Moreover, CPU41 reads the unit distance acquired from the smart phone 10 and memorize | stored in the distance setting memory | storage part 432 of RAM43 (step S402). The unit distance may be read as needed when used in steps S406, S426, and S446 described later.

  CPU41 discriminate | determines whether the input operation event to the operation part 47 by a user was detected (step S403). If it is determined that no event has been detected (“NO” in step S403), the CPU 41 repeats the process of step S403 and waits until an event is detected.

  If it is determined that an event has been detected (“YES” in step S403), the CPU 41 determines whether or not the detected event is a stop operation for counting elapsed time (step S404). If it is determined that the stop operation is detected (“YES” in step S404), the CPU 41 stops measuring the elapsed time, stops outputting the control signal to the drive circuit 51, and sets the function guideline. 66 to 68 and the second hand 61 are stopped (step S405). Based on the unit distance, the CPU 41 calculates the latest lap time, the average speed of the section, the total time, the total distance, and the overall average speed (step S406). Then, the process of the CPU 41 proceeds to step S407.

  When it is determined that the stop operation is not detected (“NO” in step S404), the CPU 41 determines whether or not the operation is a detection of an operation requesting acquisition of a lap time (step S424). If it is determined that an operation requesting acquisition of the lap time is detected (“YES” in step S424), the CPU 41 acquires the elapsed time at the timing, and the elapsed time (lap time) from the previous lap time acquisition timing. ) Is calculated. The CPU 41 stops outputting the control signal to the drive circuit 51 and stops the function hands 66 to 68 and the second hand 61 (step S425). The CPU 41 calculates the average speed based on the unit distance and the lap time (step S426). Then, the process of the CPU 41 proceeds to step S407.

  If it is determined that it is not detection of an operation requesting acquisition of a lap time (“NO” in step S424), the CPU 41 determines whether it is detection of an operation requesting acquisition of split time (step S424). S444). If it is determined that the operation requesting acquisition of the split time is detected (“YES” in step S444), the CPU 41 acquires the elapsed time at the timing and sets it as the split time. In addition, the CPU 41 stops outputting the control signal to the drive circuit 51 and stops the function hands 66 to 68 and the second hand 61 (step S445). The CPU 41 calculates the average speed based on the cumulative distance obtained by summing the distances of the sections for which the split time has been acquired so far and the split time (step S446). Then, the process of the CPU 41 proceeds to step S407.

  When it is determined that it is not detection of an operation requesting acquisition of the split time (“NO” in step S444), the CPU 41 executes other processing not related to measurement of elapsed time (step S465), Then, the process of the CPU 41 returns to step S403.

  In step S407, the CPU 41 stores the acquired elapsed time, lap time, split time, average speed, and other data in the distance setting storage unit 432 (step S407). The section numbers that are not displayed are automatically assigned in ascending order to the data stored at this time. In addition, the CPU 41 sends a control signal to the drive circuit 51 to operate the speed indicator 65 and display the calculated average speed (step S408). The average speed displayed here can be the average speed based on the last lap time even during the stop operation. Further, it is possible to switch the display of the average speed based on the last lap time and the average speed based on the total duration based on the input operation to the operation unit 47 by the user. It is also how to display either advance preferentially as capable to set configuration in the analog electronic timepiece 40 or smart phone 10.

  The CPU 41 waits for an input operation from the user and determines whether or not an input operation event has been detected (step S409). If it is determined that it is not detected (“NO” in step S409), the CPU 41 repeats the process of step S409 and continuously waits for an input operation.

  If it is determined that an input operation event has been detected (“YES” in step S409), the CPU 41 determines whether or not the detected event is a reset operation after stopping the elapsed time measurement (step S410). ). If it is determined that the reset operation is performed after the stop (“YES” in step S410), the CPU 41 initializes the positions of the function hands 66 to 68, the second hand 61 and the speed hand 65, and the current measurement value. (Step S411), and the stopwatch process is terminated.

  If it is determined that the operation is not a reset operation after the stop (“NO” in step S410), the CPU 41 resumes displaying the elapsed time (step S412). At this time, in the case of a return from the display at the time of stop, the suspended count is restarted and added to the previous measurement time to count the elapsed time. In the case of return from the lap time display, the elapsed time from the lap time acquisition timing is displayed, and in the case of return from the split time display, the elapsed time from the first measurement start timing is displayed. Then, the process of the CPU 41 returns to step S403.

FIG. 8 is a diagram illustrating an example of a stopwatch display in the analog electronic timepiece 40.
As shown in FIG. 8A, at the start of measurement, the function hands 66 to 68, the second hand 61, and the speed hand 65 are moved to the position of the initial value “0”. At this time, the current time can be continuously displayed on the minute hand 62 and the hour hand 63.

As shown in FIG. 8B, when the total measurement time, lap time, and split time are acquired, the lap time is displayed by the function hands 66 to 68 and the second hand 61. Here, the display of the function short hand 67 and the function sub-hand 68 represents a value in time units, the function long hand 66 represents a value in minutes, and the second hand 61 represents a value in seconds. Further, when the average speed of the lap is calculated, the speed pointer 65 displays this average speed. As a method of displaying the average speed by the speed indicator 65, the average speed of the previous round and the average speed of the current round may be displayed alternately. Further, the average speed of the previous round may be displayed for 1 second, and then the average speed of the current round may be displayed for 3 seconds. Further, the maximum value of the average speed of the current round and the average speed of the current round may be displayed alternately.
Here, the measurement in the stopwatch function can be performed, for example, in units of 1 millisecond according to the accuracy of the frequency signal from the frequency dividing circuit 45, but the lap time and the average speed are not necessarily the same accuracy as these. It is not necessary to be displayed in this case, and here, it is displayed in units of 1 second and 10 km / h.

Next, management of measurement time data and speed data in the speed measurement management system 1 of the present embodiment will be described.
In this speed measurement management system 1, data measured in the stopwatch mode of the analog electronic timepiece 40 can be output and transferred to the smartphone 10 for management.

  FIG. 9 is a plan view showing a measurement data list display screen in the smartphone 10.

  Here, in the stopwatch management program, by selecting the menu “Data Book” 16e for reading the acquired data history, the measurement data list 16g acquired in the past is displayed on the display screen, and new lap time data is displayed. The acquisition command “GET LAP DATA” 16 f for acquiring the “A” from the analog electronic timepiece 40 can be selected. The split time and simple measurement time can also be acquired by switching the display in the same manner.

FIG. 10 is a flowchart showing a control procedure by the CPU 11 of the measurement data acquisition process executed in the smartphone 10.
This measurement data acquisition process is started when the above acquisition command 16f is tapped and selected.

  When the measurement data acquisition process is started, the CPU 11 first requests the analog electronic timepiece 40 for communication connection by Bluetooth (step S121). When the communication connection is made, the CPU 11 requests the analog electronic timepiece 40 to transmit measurement data (step S122). The CPU 11 acquires the measurement data and stores it in the stopwatch data management unit 142 (step S123), and cancels the communication connection with the analog electronic timepiece 40 (step S124). Then, the CPU 11 ends the measurement data acquisition process. Note that the processing in step S121 may be performed by receiving a communication connection request by Bluetooth from the analog electronic timepiece 40 and performing communication connection.

  The data acquired in this way is added to the measurement data list 16g shown in FIG. 9 and can be selected.

  FIG. 11 is a plan view showing an example of a display screen of measurement data selected from the measurement data list 16g.

  On the display screen of the smartphone 10, the acquired lap time data 16h is completely displayed in units of 1 millisecond together with the circulation numbers “001” to “007”. In addition, these data can be subjected to various processes such as sorting the display order or displaying the graph as required.

As described above, the analog electronic timepiece 40 of the present embodiment includes the operation unit 47 that receives user operations, the Bluetooth module 48 that communicates with the smartphone 10, the speed indicator 65 that is rotatably provided, and the oscillation. A circuit 64, a frequency dividing circuit 65, a CPU 41, and the like are provided.
The CPU 41 measures the time between timings designated by the operation on the operation unit 47 based on the frequency signal input from the frequency divider circuit 65, and sets the unit distance setting value acquired from the smartphone 10 by the Bluetooth module 48. Then, the speed is calculated by dividing by the measured time, and the speed pointer 65 is rotated to display the calculated speed.
Accordingly, speed calculation and display based on the measured elapsed time can be performed more easily and easily read while easy time measurement using the stopwatch function of the electronic timepiece is performed.
In particular, a distance that was difficult to set with the analog electronic timepiece 40 is set with the smartphone 10 and transmitted to the analog electronic timepiece 40, so that the speed is easily calculated from the measurement time, and the speed-only display by the speed pointer 65 is displayed by the user. Can be easily read.
In particular, using a wearable analog electronic timepiece such as a wristwatch makes it difficult to keep it by hand all the time, and it is difficult to perform measurements with the smartphone 10 because it is necessary to remove it from the storage unit during operation. Even in the situation, the analog electronic timepiece 40 can easily and accurately measure the speed information.

  In addition, since the measured time data can be output to the smartphone 10 by the Bluetooth module 48, it is not only displayed on the analog electronic timepiece 40, but also various processes and analyzes are performed outside. It can be used effectively.

  Further, the lap times can be acquired as period values based on the input operation from the operation unit 47, and the speeds of the plurality of periods are calculated using the unit distances set and acquired for the lap times of the plurality of periods, respectively. I can do it. Therefore, it is possible to easily calculate and display the speed at each lap based on the lap time, even when the unit distance for each lap time is different and the unit distance needs to be set for each. The analog electronic timepiece 40 can be easily set by using the smartphone 10, and the measurement time can be easily converted into a speed value and displayed.

  In addition, the time from the start of measurement and the lap time of each period can be displayed in real time using the second hand 61 and the function hands 66 to 68, so that the user can use the normal stopwatch function and speed display in combination. Can easily acquire information related to speed measurement.

  Further, when the measurement time data is output to the smartphone 10 by the Bluetooth module 48, the measurement data can be output with a measurable accuracy, whereas the speed by the speed pointer 65, the second hand 61, and the function pointers 66-68. In addition, the display of the elapsed time can be displayed with reduced accuracy within a range required by the user. Therefore, while preventing the increase in cost by making the pointer operation of the analog electronic timepiece 40 more accurate than necessary and the complicated display of the pointer, it is rather difficult for the user to know the value, but the data can be easily acquired. The smartphone 10 that can be browsed and processed can display and process highly accurate data.

  The analog electronic timepiece 40 includes an operation unit 18 that receives user operations and a Bluetooth module 24 that communicates with the analog electronic timepiece 40, and determines a value for setting a unit distance based on an input operation to the operation unit 18. Then, by configuring the speed measurement management system in combination with the smartphone 10 that outputs the unit distance value set by the Bluetooth module 24 to the analog electronic timepiece 40, the setting data of the setting of the analog electronic timepiece 40 is managed by the smartphone 10. Therefore, it is easy to set the distance related to the speed display, and it is possible to display the speed easily and easily based on the stopwatch measurement in the analog electronic timepiece 40.

The minute hand 67 and the function secondary hand 68 may indicate minutes, the function long hand 66 may indicate seconds, and the second hand 61 may indicate 1/20 seconds. Also, the display accuracy may be switched.

  Moreover, in the said embodiment, although data transmission / reception was performed between the analog electronic timepiece 40 and the smart phone 10 using Bluetooth communication, a communication method is not restricted to this. Other communication methods such as wireless LAN, infrared communication, and wired connection may be used. However, it is more preferable that the power consumption is not large and that the size of the plug for connecting the cable and the module of the receiving unit is not required to be increased.
