Description

 The present invention relates to a speed measuring device and a program for measuring speed related to sports.

  A device using a Doppler sensor is known as a velocity measuring device for measuring the velocity of a moving measuring object. In this method, microwaves are irradiated toward an object that is an object to be measured, and reflected waves from the object are measured. When the object is moving with respect to the traveling direction of the microwave, the frequency of the reflected wave changes due to the Doppler effect, so the speed of the object can be calculated by comparing this with the frequency of the emitted wave. it can.

As a conventional speed measuring device for sports using a Doppler sensor or the like, a speed measuring device for baseball (called a speed gun) used to measure the speed (ball speed) of a ball thrown by a pitcher in sports such as baseball. Is known). In a baseball speed measurement device, for example, when a user pulls a trigger (presses a switch), the speed measurement is started, and the speed measured (detected) first is determined and displayed as the speed of the ball. Since the thrown ball decelerates, the velocity measured first after the measurement is started is displayed as the velocity of the ball.

Moreover, as shown in Patent Documents 1 and 2, a speed measuring device for golf is known as a conventional speed measuring device for sports. In the golf speed measurement device, for example, measurement of speed is started, and the maximum value of the measured speed is determined and displayed as the swing speed of the golf club. When an object to be measured that accelerates rapidly from a state of zero velocity and reaches the maximum speed at the point of hitting the ball, such as a golf club swinging motion, the object to be measured is within the detection range of the Doppler sensor. This is because the maximum speed of swing is not always captured by the method of displaying the speed measured first after the start of measurement.

As described above, the conventional speed measurement device realizes a speed measurement device suitable for the sport to be measured by adopting a measurement method optimized for each sport to be measured.

Further, for example, in a baseball speed measuring device, the initial speed and final speed of a ball are measured and displayed, whereas in a golf speed measuring device, as disclosed in Patent Document 2, the swing speed of a golf club is shown. The display contents to be displayed based on the speed of the measurement object and the measured speed, such as displaying the speed of the ball and the estimated flight distance, are also optimized for each sport to be measured.

Further, as shown in Patent Document 2, the installation method is a structure suitable for use on the ground if it is a speed measuring device for golf, while the speed measuring device for baseball is fixed to a tripod. The structure is also different, such as a configuration suitable for use.

Since the measurement method, display content, structure, etc. are different for each sport to be measured in this way, for example, when you want to measure the speed of multiple sports, such as schools and sports clubs, for each sport It was necessary to purchase a speed measuring device.

  An object of the present invention is to provide a speed measuring device suitable for measuring speeds related to a plurality of different sports.

  In order to solve the above problems, the present invention detects (1) a speed based on a microwave Doppler sensor and a Doppler signal output from the microwave Doppler sensor, and displays display information based on the speed. A speed measurement apparatus for sports comprising control means for generating and displaying on the display means, wherein the control means is means for generating the display information in a predetermined unit of motion in the sport to be measured Switching between the processing means, general-purpose processing means for generating the instantaneous velocity repeatedly obtained at predetermined time intervals as the display information, and the dedicated processing means and the general-purpose processing means based on a switching instruction from the user Switching means.

In this way, the user can display the dedicated mode in which information for display in a predetermined unit of motion in the sport to be measured is displayed, and the instantaneous speed repeatedly obtained at predetermined time intervals as necessary. It can be used by switching to the general-purpose mode. Therefore, it is possible to provide a speed measuring device suitable for measuring speeds related to a plurality of different sports.

  The display information may be speed information. The display information may be information on the speed itself or information obtained from the speed (for example, a moving distance or a flying distance). The display information may be numerical information or may be information of various aspects such as a graph.

  The switching unit may be configured to switch between the dedicated processing unit and the general-purpose processing unit, and a switching instruction from the user may be input from the input unit.

  The dedicated processing means is means for generating the display information in a predetermined operation unit in the sport to be measured, and the display information may be generated by processing specialized for the specific sport to be measured, The display information to be generated may be information specialized for the sport to be measured.

  The dedicated processing means generates the display information based on the Doppler signal output from the microwave Doppler sensor. For example, the Doppler signal output from the microwave Doppler sensor is frequency-analyzed during the one operation unit. Then, the repetition speed may be calculated, the repeatedly calculated speed may be recorded, and display information to be displayed in the one operation unit may be generated based on the recorded speed history. As the display information, for example, a value when the speed within the speed range of the measurement target first appears in the speed history of the one operation unit is generated as initial speed information, or the speed history of the one operation unit Various values can be taken, such as generating a value when the velocity within the velocity range of the measurement target appears last as final velocity information. For example, when a graph in which speed histories in one operation unit are arranged in time series as display information is generated, the graph in the one operation unit is displayed.

  On the other hand, the general-purpose processing means is a means for generating the instantaneous speed repeatedly obtained at a predetermined time interval as the display information. Unlike the dedicated processing means, the general-purpose processing means is not limited to one predetermined operation unit in the sport to be measured. The instantaneous speed is continuously displayed as the display information. The general-purpose processing means may generate display information by a process that is not specific to a specific sport, and the display information to be generated is preferably information that is not specific to a specific sport. The predetermined time interval may be a time interval suitable for common measurement in various sports. The predetermined time interval may be at least 1 second or less, and preferably 100 milliseconds or less. As the display information, for example, a history of instantaneous velocities obtained repeatedly at predetermined time intervals may be stored and displayed. For example, when generating a graph in which instantaneous speed histories are arranged in time series as display information, the latest predetermined number of instantaneous speed history graphs may be displayed.

  (2) The dedicated processing means may specify the start and end of a predetermined motion unit in the sport to be measured based on a Doppler signal output from the microwave Doppler sensor.

  The dedicated processing means may specify the start and end of a predetermined unit of motion in the sport to be measured based on information obtained from various sensors or the like. However, it may be specified based on the Doppler signal. In this way, it is possible to provide a speed measurement device suitable for measuring speeds related to a plurality of different sports without providing a separate sensor and without cost.

  (3) Provided with an instruction input means for inputting a start instruction and an end instruction from the user, wherein the general-purpose processing means receives the start instruction from the user by the instruction input means and then the user by the instruction input means. Until the end instruction is input, the instantaneous speed obtained repeatedly at the predetermined time interval may be generated as the display information and displayed on the display means.

  The general-purpose processing means generates the instantaneous speed as the display information and displays it on the display means from turning on the power or switching to the general-purpose processing means by the switching means to switching off the power or switching to the dedicated processing means. However, this is particularly good. This is because the speed in a range in accordance with the user's intention according to various sports can be measured universally.

  (4) The control means may perform a process of causing the display means to display information indicating whether the processing is being performed by the dedicated processing means or the general-purpose processing means.

In this way, it is possible to easily confirm whether the speed is being measured by the dedicated processing means or the speed is being measured by the general-purpose processing means. It is therefore suitable for measuring the speed for a plurality of different sports.

(5) The display information specialized for at least one of pitching, batting, golf, and short-distance running as the sport to be measured. And the control means determines which of the processing means of each of the dedicated processing means is switched, and which sport the measurement target sport currently being processed is. It is good to provide the means to display the information to show on the said display means.
In this way, the measurement can be switched to a process close to the sport to be measured, and it can be easily grasped which speed measurement process is suitable for which sport.

  (6) The general-purpose processing means may perform processing for storing and displaying the highest speed among the instantaneous speeds measured from the start of measurement to the present as the display information.

  (7) The general-purpose processing unit may perform a process of causing the display unit to display a graph indicating a time-series change in the instantaneous speed as the display information.

  (8) A plurality of the dedicated processing means may be provided, and the display direction of the display information on the display means may be different between the dedicated processing means.

  The dedicated processing means generates the display information in a predetermined unit of motion in the sport to be measured and causes the display unit to display the information. Therefore, there is a case where the unit of motion and the display unit are related to the viewing direction of the user. is there. When the positional relationship between the microwave Doppler sensor and the display means is fixed, a particularly excellent effect is obtained.

In addition, for example, since the microwave Doppler sensor is usually measured toward the measurement target, a person who views the display information often sees the display information from a direction other than the microwave emission direction. However, for example, when the measurement person himself / herself moves the measurement object or the measurement object and also becomes the person who views the display information, such as measurement of a swing of a golf club, You will see the information for display. Therefore, according to the characteristics in the sport to be measured, by changing the display direction of the display information to the display means between the dedicated processing means, the display of the display information is easy to see, An easy-to-use speed measuring device can be realized when measuring speeds related to a plurality of different sports.

  (9) a plurality of dedicated processing means, wherein the dedicated processing means generates a plurality of types of information as the display information, and causes the display means to simultaneously display the generated types of information; A plurality of types of information are generated as the display information, and only one of the generated types of information can be displayed on the display means. When displaying the information, it is preferable to display the information for one display larger than when displaying the plurality of types of information at the same time.

In this way, for example, in a sport to be measured where the distance between the person viewing the display information and the display means is long, the one display information is large and easy to see, and the person viewing the display information In a sport to be measured that is close to the display means, a plurality of pieces of information can be grasped simultaneously.

  (10) When the dedicated processing means completes the processing mode for generating and terminating the display information in the one operation unit and the generation of the display information in the one operation unit, the dedicated processing means again in the next one operation unit A processing mode for generating the display information may be provided.

  (11) A plurality of dedicated processing means are provided, and the dedicated processing means writes the display information for each operation unit to an external memory for each operation unit, and does not write to the external memory for each operation unit. It is preferable to store the measurement result in the internal memory and write the measurement result in the internal memory to the external memory based on an instruction from the user.

  (12) The speed measuring device includes a main body and a slave unit that receives and displays the display information wirelessly transmitted from the main body, and the slave unit wirelessly transmits the display information from the main body. Of these, only those that match preset body identification information may be displayed.

The section displays the distance between the detected initial speed and the final speed. When only the instantaneous speed can be detected, such as when the section where the speed is detected is short, the section is displayed with “0” or “---”. Each time one unit of measurement is performed, these calculated values are displayed blinking for the time set in the system settings (the initial value is 3 seconds). It changes to lighting and notifies that the detection result has been updated. The blinking time of the speed display (initial value: 3 seconds) can be changed by system setting. Up to 200 detection results are recorded in the nonvolatile memory of the control unit 13 of the main body 10 together with the recording number. Therefore, even if the battery is removed or the battery is exhausted, the detection result record is not erased. The detection results recorded on the main unit can be saved to the microSD card in the system settings. After that, it is determined whether the detection method set / stored in the control unit 13 is “once” or “continuous”. If it is “once”, the measurement process is terminated and currently displayed. In the case of continuous display, the measurement process in the pitching mode is performed again (that is, the next unit of measurement is started). During these processes, it is detected whether or not pressing of the start / stop button 17b is detected. When pressing of the start / stop button 17b is detected, the measurement process is terminated and the currently displayed screen is displayed. It will be in the state.

  Next, the batting mode will be described. In the batting mode, in the batting mode, the bat swing speed in baseball and softball, the initial hitting speed, and the estimated hitting distance of the hitting ball are displayed on the display unit 14 of the main body 10 and transmitted to the slave unit 30. Display the bat swing speed. As shown in FIG. 10 (a), a base such as a desk or a camera tripod is used for stable detection in which the main body 10 is installed from the oblique rear side (opposite of the batter) toward the bat swing position. It is desirable to install. The distance from the batter to the main body 10 is set within about 5 m, and it is installed in a place where it is not behind the catcher.

  As a specific process, as shown in FIG. 10B, after the batting mode is selected, the control unit 13 starts the batting mode measurement process when detecting the pressing of the start / stop button 17b. In the measurement process in the batting mode, the measurement is performed with the time within the range of the speed of the hitting operation of the bat as a unit, and the measurement result obtained within the unit period is displayed. As shown in FIG. 10B, the measurement results are the bat swing speed (bat), the initial velocity of the hit ball (hit ball), and the estimated flight distance (fly distance) of the hit ball. In the flight distance display, a flight distance as a guide is calculated from the velocity of the hit ball under the conditions of “ball angle: 45 degrees” and “hit height: 1 m”. The flight distance is based on the hitting ball in the center direction, and the hitting ball in the first and third base directions may have a large error. The bat swing speed (bat) and the initial hit speed (hit) are calculated by, for example, a known method. When the initial velocity (hit ball) of the hit ball is not detected, the initial velocity (hit ball) of the hit ball and the estimated flight distance (fly distance) of the hit ball are not displayed. Therefore, as shown in FIG. 10C, the display contents of the detection result differ as follows depending on the batter's operating conditions. That is, when the ball is hit or knocked, the bat swing speed (bat), the initial velocity of the hit ball (hit ball), and the estimated flight distance (fly distance) of the hit ball are measured and displayed. When the ball is swung or shaken, the bat swing speed (bat) is measured and displayed. Each time one unit of measurement is performed, these calculated values are displayed blinking for the time set in the system settings (the initial value is 3 seconds). It changes to lighting and notifies that the detection result has been updated. The blinking time of the speed display (initial value: 3 seconds) can be changed by system setting. Up to 200 detection results are recorded in the nonvolatile memory of the control unit 13 of the main body 10 together with the recording number. Therefore, even if the battery is removed or the battery is exhausted, the detection result record is not erased. The detection results recorded on the main unit can be saved to the microSD card in the system settings. After that, it is determined whether the detection method set / stored in the control unit 13 is “once” or “continuous”. If it is “once”, the measurement process is terminated and currently displayed. In the case of continuous display, the measurement process in the batting mode is performed again (that is, the next unit of measurement is started). During these processes, it is detected whether or not pressing of the start / stop button 17b is detected. When pressing of the start / stop button 17b is detected, the measurement process is terminated and the currently displayed screen is displayed. It will be in the state.

  Next, the golf mode will be described with reference to FIGS. In the golf mode, the head speed, ball speed, estimated flight distance, and meet rate in the golf club swing are displayed on the display unit 14 of the main body 10.

  As a specific process, as shown in FIG. 11, after the golf mode is selected, the control unit 13 determines whether or not the right button of the main body 10 is detected, and the right button is detected. In this case, the process proceeds to the setting menu process. If pressing of the right button is not detected, it is determined whether pressing of the start / stop button 17b is detected. When the pressing of the start / stop button 17b is detected, the measurement process of the golf mode is started. When the pressing of the start / stop button 17b is not detected, the process returns to the determination of the pressing of the right button.

11, the display on the display unit 14 in the golf mode is different from the other modes (the sensor 11 side is the upper side of the screen), so that the sensor 11 side is the lower side of the screen. Processing to display the image upside down is performed. Thus, in the golf mode, the display direction of the screen is different from the other modes. When measuring in the golf mode, unlike the measurement in other modes, when the measurement person himself / herself moves the measurement object or measurement object, and also becomes the person who sees the measurement result, The measurement result is viewed from the emission direction side of the microwave Doppler sensor 11. By doing so, the display of the measurement result is easy to see in each mode, and it is easy to use when measuring speeds related to a plurality of different sports. It is possible to realize a speed measuring device with good speed.

  In the processing of the setting menu, the setting menu is displayed, the pressing of the upper button and the lower button of the main body 10 is detected, and the right button is pressed while the selection item “club type selection” is selected in the setting menu. Detect whether it was done. When the right button is pressed while “club type selection” is selected, a club type selection menu is displayed. The club type selection menu displays the selection items 1W, 3W, 5W, 3I, 4I, 5I, 6I, 7I, 8I, 9I, User1, User2, and User3 in order from top to bottom, and presses the up / down buttons. And the club currently selected from these selection items is highlighted. If pressing of the set button is detected, the club being selected is set as the selected club (stored in the non-volatile memory of the control unit 13), and the process returns to after the above-described golf mode is selected. . The initial value of the club type is 1W.

After the user presses the start / stop button 17b, the user installs the microwave Doppler sensor 11 of the main body 10 in the direction of launching the ball as shown in FIG. The main body 11 is placed on a flat place without ups and downs, and installed so that there are no obstacles between the main body and the ball.

In the measurement process in the golf mode, the measurement is performed with the time within the range of the swing motion speed of the golf club as one unit, and the measurement result obtained in the period of one unit is displayed. The measurement result is displayed by selecting from the items “head speed / ball speed / meet ratio / estimated flight distance / all” in the “screen select” setting of the setting menu, and using the selected contents. The initial value is set to “head speed”. As shown in the lower part of FIG. 11, when “head speed” is set, the head speed is displayed. When “ball speed” is displayed, the ball speed is displayed, and the “meet ratio” is set. If it is displayed, the meet rate is displayed. If it is set to “Estimated flight distance”, the estimated flight distance is displayed as shown in FIG. 12A, and “All” is set. If it is, the head speed, ball speed, meet rate, and estimated flight distance are all displayed as shown in FIG. When only one of “head speed / ball speed / meet rate / estimated flight distance” is displayed as shown in the lower part of FIG. 11 and the left side of FIG. 12 (a), it is shown on the right side of FIG. 12 (a). Compared to the case where all the head speed, ball speed, meet rate, and estimated flight distance are displayed, the “head speed / ball speed / meet rate / estimated flight distance” set as the display target is displayed larger. I am doing so. In the golf mode, unlike the measurement in the other modes, the measurement person himself / herself becomes a person who swings the golf club as the measurement object and also becomes a person who sees the measurement result. Although only one of “head speed / ball speed / meet rate / estimated flight distance” is displayed, only one measurement result is displayed, which is easy to see. On the other hand, in other modes, a plurality of information can be grasped simultaneously. The head speed, ball speed, meet rate, and estimated flight distance may be measured and calculated by the method described in, for example, Japanese Patent Application Laid-Open No. 2010-005289. The meat rate is calculated by “ball speed ÷ head speed”. If the ball speed can be detected, the estimated flight distance is calculated from the ball speed. If the ball speed cannot be detected, such as a ball with a high trajectory (a ball hit with a large iron, etc.), the head speed is calculated. Since the ball speed takes into account the coefficient of restitution of the head and the ball, a more accurate numerical value can be calculated as compared with the estimated flight distance from the head speed. The loft angle for calculating the estimated flight distance may be set for each club type as shown in FIG. 13, for example, and the estimated flight distance may be calculated using the set value. When the obtained meet rate is 1.40 (initial value) or more, a nice shot display is performed as shown in FIG. Note that. The meet rate value (= the nice shot reference value) can be changed in the setting menu. Each time one unit of measurement is performed, these calculated values are displayed blinking for the time set in the system settings (the initial value is 3 seconds). It changes to lighting and notifies that the detection result has been updated. The blinking time (initial value: 3 seconds) can be changed by system setting. Up to 500 detection results are recorded in the nonvolatile memory of the control unit 13 of the main body 10 together with the recording number. Therefore, even if the battery is removed or the battery is exhausted, the detection result record is not erased. The detection results recorded on the main unit can be saved to the microSD card in the system settings. The nice shot display is displayed while the detection result is blinking. When these processes are completed, the golf mode measurement process is performed again (that is, the next unit of measurement is started). After a measurement result is obtained, it may be shifted to the next measurement after a certain time has passed (with a measurement prohibition period in between). During these processes, it is detected whether or not pressing of the start / stop button 17b is detected. When pressing of the start / stop button 17b is detected, the measurement process is terminated and the currently displayed screen is displayed. It will be in the state.

  Next, the short distance running mode will be described. In the short-distance running mode, the speed at which a person runs in 100 m running or the like is displayed on the display unit of the main body 10 as a numerical value or a graph and transmitted to the slave unit 30. The subunit | mobile_unit 30 displays the maximum speed (the decimal part is rounded off). Make sure that the course you run is straight and that there are no other runners. This machine can display the speed of running a straight distance of about 20-120m.

As shown in FIG. 14A, the main body 10 is installed at a position of about 3 to 5 m just behind the start position, and the microwave Doppler sensor 11 is directed around the runner's back. In order to perform stable detection, it is desirable to install using a table such as a desk or a camera tripod.

  As a specific process, as shown in FIG. 14 (b), the control unit 13 detects the pressing of the start / stop button 17b after the sprint mode is selected, and then measures the sprint mode. To start. In the measurement process in the sprint mode, after the speed is first detected, the distance is obtained by integrating the distance based on the detected speed and time, and the distance is set in the setting menu (range of 20 to 120 m). (The initial value is set to 100 m.) When the value reaches, the measurement is terminated as one unit. As the display format, either “graph display” or “numerical value display” is set in the setting menu, and display is performed in the set display format. When “Graph display” is set, as shown on the left side of FIG. 14C, the maximum speed measured in one unit and the speed measured at any time in one unit are shown on the vertical axis and setting menu. The graph is displayed on the horizontal axis corresponding to the setting in the “graph horizontal axis item” (“time (S)” or “distance (m)”, the initial value is “time”)). The vertical axis is displayed as “speed (km / h)”, and when the pressing of the upper button / lower button of the main body is detected, the display range of the vertical axis (speed) is scroll-displayed. When “numerical value display” is set, “highest speed”, “A time”, “A distance”, “B time”, and “B distance” are displayed as shown on the right side of FIG. To do. “Maximum speed” displays the maximum speed obtained in one unit. In “A time”, the time required to reach the maximum speed is displayed. In “A distance”, the distance required to reach the maximum speed is displayed. In “B time”, the time during which the maximum speed is maintained (the time from when the maximum speed is detected to the deceleration corresponding to the maximum speed holding condition set in the setting menu (initial value 2 km / h)) is displayed. . “B distance” displays the maximum speed holding distance (the distance from the maximum speed to the detection of the deceleration corresponding to the maximum speed holding condition (initial value 2 km / h) set in the setting menu). Only the latest one of these detection results is recorded in the nonvolatile memory of the control unit 13 of the main body 10. Therefore, even if the battery is removed or the battery is exhausted, the detection result record is not erased. The detection results recorded on the main unit can be automatically saved on the microSD card. After that, it is determined whether the detection method set / stored in the control unit 13 is “once” or “continuous”. If it is “once”, the measurement process is terminated and currently displayed. In the case of continuous, the sprint mode measurement process is performed again (that is, the next unit of measurement is started). During these processes, it is detected whether or not pressing of the start / stop button 17b is detected. When pressing of the start / stop button 17b is detected, the measurement process is terminated and the currently displayed screen is displayed. It will be in the state.

As described above, in the short-distance running mode, a graph in which speed histories in one unit are arranged in time series as display information is also generated, and the graph in the one unit is displayed.

  Next, the general-purpose mode will be described. In the general-purpose mode, the traveling speed of motor vehicles and motorcycles (motor sports) and the speed of skiing and snowboarding are displayed on the display unit 14 of the main body 10 as numerical values and graphs and transmitted to the slave unit 30. The subunit | mobile_unit 30 displays the highest speed in the latest 5 second received on the display part 34. FIG.

As shown in FIG. 15A, the main body 10 is installed with the microwave Doppler sensor 11 of the main body 10 facing the front or rear of the moving object (automobile or the like). In order to perform stable detection, it is desirable to install using a table such as a desk or a camera tripod.

  As a specific process, as shown in FIG. 15B, when the general-purpose mode is selected, the control unit 13 starts the measurement process in the general-purpose mode when the pressing of the start / stop button 17b is detected. In the measurement process in the general-purpose mode, the speed is detected at any time (can be set every 100 ms between every 100 ms and 1000 ms in the setting menu, and the initial value is every 500 ms), and as shown in FIG. The detection speed, the maximum speed among the detection speeds from the start of the measurement process to the present time, and a graph are displayed. The graph display is the speed measured from time to time as the vertical axis, the setting in the “Graph horizontal axis item” of the setting menu (“Time (S)” or “Distance (m)”, the initial value is “Time” Is the horizontal axis. The vertical axis is displayed as “speed (km / h)”, and when the pressing of the upper button / lower button of the main body 10 is detected, the display range of the vertical axis (speed) is scroll-displayed. When the speed display reaches the right end of the horizontal axis, the graph is scrolled so that the detection speed for the past 50 seconds is displayed with the latest detection speed as the right end. These detection results are recorded in the nonvolatile memory of the control unit 13 of the main body 10 as needed. Therefore, even if the battery is removed or the battery is exhausted, the detection result record is not erased. The detection results recorded on the main unit can be automatically saved on the microSD card. During these processes, it is detected whether or not pressing of the start / stop button 17b is detected. When pressing of the start / stop button 17b is detected, the measurement process is terminated and the currently displayed screen is displayed. It will be in the state. Thus, unlike the other modes, the general-purpose mode performs continuous measurement without performing measurement for each unit.

As described above, in the general-purpose mode, a graph in which the history of the instantaneous speed is arranged in time series as display information is generated, and the graph of the instantaneous speed history of the latest predetermined number (the number corresponding to the past 50 seconds) is displayed. .

  As described above, the main body 10 of the velocity measuring device of the present embodiment is output from the microwave Doppler sensor 11, the amplifier 12 that amplifies the Doppler signal output from the microwave Doppler sensor 11, and the amplifier 12. A speed measurement device for sports comprising a control unit 13 that detects a speed based on a Doppler signal, generates display information based on the speed, and displays the information on the display unit 14. Dedicated processing (pitching mode processing, batting mode processing, golf mode processing, sprint running mode processing) for generating display information in a predetermined unit of motion (one unit) in sports It is a process that generates instantaneous speed as display information without being specialized for sports. Comprising processing (processing of generic mode), and switching means based on the switching instruction from a user switching between the general processing unit and the dedicated processing unit. Based on a switching instruction from the operation unit 14 from the user, switching processing (main menu processing) for switching between dedicated processing and general-purpose processing is performed.

In this way, the user can display information for display in a predetermined unit of motion in the sport to be measured as necessary (pitching mode, batting mode, golf mode, sprint mode), It can be used by switching to a general-purpose mode in which the instantaneous velocity repeatedly obtained at a predetermined time interval is displayed. Therefore, it becomes a speed measuring apparatus suitable for measuring the speed regarding several different sports.

In each dedicated process, as a process of generating display information (measurement result) based on the Doppler signal output from the microwave Doppler sensor 11, for example, the Doppler signal output from the amplifier 12 for one unit is used. It is preferable to calculate the repetition speed by frequency analysis, record the repeatedly calculated speed in the RAM, and generate display information to be displayed in one unit based on the history of the recorded speed.

  In general-purpose processing, the instantaneous speed obtained repeatedly at a predetermined time interval is generated as display information (measurement results). Therefore, unlike the dedicated processing, it is not limited to a predetermined unit of motion in the sport to be measured, and is continuous. The instantaneous speed is displayed as display information. In the general-purpose process, display information is generated by a process that is not specific to a specific sport, and the generated display information is also information that is not specific to a specific sport. The predetermined time interval is a time interval suitable for common measurement in various sports. As described above, the predetermined time interval can be set every 100 ms between 100 ms and 1000 ms in the setting menu, and the initial value is set every 500 ms.

  In each dedicated process, the start and end of a predetermined unit of motion in the sport to be measured is specified based on the Doppler signal, so another sensor is provided to start and end the predetermined unit of motion. There is no need to specify the cost and the cost can be reduced.

In the general-purpose processing, the instantaneous velocity repeatedly obtained at predetermined time intervals from when the start instruction is input by the user until the end instruction is input is generated and displayed as display information. It is possible to measure a range of speeds according to the user's intention according to the general purpose.
In each processing mode, the setting menu is provided with the following function, and when selected, the function is executed.

  A “no-count” menu is provided, and a no-count function for erasing the latest detection result from the memory is provided. In this way, when there is a measurement error, it is easy to prevent the result from being recorded.

As shown in FIG. 16, an error in display information (measurement result) may occur depending on the installation state of the main body. Therefore, a “diagonal direction correction” menu is provided, and the moving direction of the measurement object and the microwave emission direction are defined. An angle may be set, and the angle may be corrected and displayed using the set angle.
The setting menu has the same configuration as that of the main menu shown in FIG. 5, for example, as shown in FIG.
