Description

【Technical Field】 【0001】 The present invention relates to an evaluation system, an evaluation device, an evaluation method, and a program. 【Background Art】 【0002】 As a method for measuring the moving speed of a moving object (hereinafter, may be simply referred to as "speed"), the Doppler method is known in which a transmission wave such as radio waves or ultrasonic waves is transmitted and the speed of the moving object is calculated based on the reflected wave received from the moving object. Patent Document 1 below describes evaluating the speed and moving direction of a moving object using a plurality of antennas and a plurality of Doppler sensors. Further, Patent Document 2 below describes a portable measuring device incorporating two antennas and two Doppler sensors. 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Unexamined Patent Application Publication No. 2012-063151 【Patent Document 2】 Japanese Unexamined Patent Application Publication No. 2014-153340 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 When measuring speed using a Doppler sensor, the speed of a moving object in the direction the antenna is pointing is measured. If a moving object is moving at an angle to the direction the antenna is pointing, the measured speed will be reduced according to the angle of movement. Therefore, by using multiple antennas and multiple Doppler sensors to simultaneously measure the speed of a moving object from multiple directions, it is possible to evaluate the direction of movement of the moving object. However, the optimal distance between antennas and the orientation of each antenna will vary depending on the type of moving object being measured and the nature of the evaluation. Furthermore, for example, if a device is constructed by integrating multiple antennas and multiple Doppler sensors placed over a wide area, the overall device will be enormous, limiting its portability and installation. 【0005】 The purpose of this disclosure is to provide an evaluation system, evaluation device, evaluation method, and program that can appropriately evaluate the movement of a moving object according to the type of moving object and the content of the movement evaluation. [Means for solving the problem] 【0006】 The evaluation system relating to this disclosure is an evaluation system having a plurality of measuring devices and an evaluation device. Each of the plurality of measuring devices includes a Doppler sensor, a speed calculation unit that calculates the speed of a moving object based on the output from the Doppler sensor, a display control unit that displays the speed information calculated by the speed calculation unit on a display means, and a transmission unit that wirelessly transmits the speed information calculated by the speed calculation unit to the evaluation device. The evaluation device includes a receiving unit that receives the speed information from each of the plurality of measuring devices, and an evaluation information output unit that outputs evaluation information regarding the movement of the moving object based on the plurality of speed information received by the receiving unit. This makes it possible to appropriately evaluate the movement of a moving object. 【0007】 Furthermore, the evaluation device according to this disclosure includes a receiving unit that receives information on the moving speed of a moving object from each of a plurality of measuring devices, each having a display control unit that displays the information on the moving speed of a moving object on a display means, and an evaluation information output unit that outputs evaluation information regarding the movement of the moving object based on the plurality of pieces of information on the moving speed received by the receiving unit. This makes it possible to appropriately evaluate the movement of a moving object. 【0008】 Furthermore, the evaluation method according to this disclosure includes a receiving step in which a receiving unit receives information on the moving speed of a moving object from each of a plurality of measuring devices having a display control unit that causes the information on the moving speed of the moving object to be displayed on a display means, and an output step in which an output unit outputs evaluation information regarding the movement of the moving object based on the plurality of information on the moving speed received by the receiving unit in the receiving step. This makes it possible to appropriately evaluate the movement of a moving object. 【0009】 Furthermore, the program relating to this disclosure causes a computer to execute a procedure for receiving information on the moving speed of a moving object from each of a plurality of measuring devices, each having a display control unit that displays information on the moving speed of the moving object on a display means, and a procedure for outputting evaluation information regarding the movement of the moving object based on the plurality of received moving speed information. This makes it possible to appropriately evaluate the movement of a moving object using a computer.

System Configuration] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. FIG. 1 is a diagram showing the configuration of an evaluation system 1 which is an example of an embodiment of the present disclosure. The evaluation system 1 described in this embodiment includes a plurality of measurement devices 10 and one evaluation device 20. Each of the plurality of measurement devices 10 measures and outputs the moving speed of a moving object such as a baseball thrown by a person, the tip portion of a bat swung by a person, or the club head of a golf club. As will be described later, the evaluation device 20 wirelessly receives data from each of the plurality of measurement devices 10 and outputs evaluation information regarding the movement of the moving object. Although FIG. 1 shows three measurement devices 10 (10A to 10C), the number of measurement devices 10 included in the evaluation system 1 may be two or a plurality of four or more. 【0012】 As shown in FIG. 1, the plurality of measurement devices 10 may be attached to a dedicated support device 81 (an attached member). The support device 81 determines the arrangement position and orientation of each of the plurality of measurement devices 10. In the example shown in FIG. 1, the support device 81 has a metal plate shaped to extend in the left - right direction. The plurality of measurement devices 10 are attached to the support device 81 by screws or the like passing through holes formed in the metal plate so as to face different directions from each other. The support device 81 may have legs such as a tripod that can adjust the height position of the metal plate (that is, the height position of the plurality of measurement devices 10). 【0013】 [2. Hardware Configuration] Figure 2 shows an example of the hardware configuration of the measuring device 10 and the evaluation device 20. The measuring device 10 is a small computer that can be carried by hand, and as shown in Figure 2, it includes a processor 11, a memory unit 12, a communication unit 13, a display unit 14, and an operation unit 15. The processor 11 is a program control device such as a CPU (Central Processing Unit). The memory unit 12 is a memory element such as a ROM (Read Only Memory) or RAM (Random Access Memory). The memory unit 12 stores data such as programs executed by the processor 11. The communication unit 13 is a communication interface corresponding to a given wireless communication standard. The display unit 14 is a display device such as a liquid crystal display or an organic EL (Electro Luminescence) display, which displays various images according to the instructions of the processor 11. The operation unit 15 is a user interface such as buttons and switches, which receives user input and outputs a signal indicating the content to the processor 11. The processor 11, memory unit 12, and communication unit 13 are housed inside the case 19 that constitutes the outer shell of the measuring device 10. Furthermore, as shown in Figure 1, the display unit 14 and operation unit 15 are provided on the outer surface of the case 19 of the measuring device 10. 【0014】 Each of the multiple measuring devices 10 includes an antenna 16 and a Doppler sensor 17. The antenna 16 and Doppler sensor 17 are housed inside the case 19 of the measuring device 10, along with a processor 11, a memory unit 12, a communication unit 13, etc. The antenna 16 transmits a transmission wave, such as a microwave, toward a moving object based on a transmission signal supplied from the Doppler sensor 17, and receives the reflected wave reflected by the moving object and supplies the received signal to the Doppler sensor 17. The Doppler sensor 17 supplies a transmission signal to the antenna 16 and generates a Doppler signal having a Doppler frequency based on the received signal supplied from the antenna 16. The antenna 16 is a directional antenna, such as a patch antenna, a horn antenna, or a parabolic antenna, and is oriented in a predetermined direction from the measuring device 10. In this embodiment, the antenna 16 is oriented toward the rear of the measuring device 10. As shown in Figure 1, the rear end of the case 19 of the measuring device 10 is provided with a cover portion 19a made of a material that can transmit the transmitted wave from the antenna 16 and the reflected wave reflected by the moving body. This provides dust protection and protection for the antenna 16. 【0015】 The evaluation device 20 is a computer such as a smartphone, tablet computer, or personal computer, and as shown in Figure 2, it includes a processor 21, a storage unit 22, a communication unit 23, a display unit 24, and an operation unit 25. The processor 21 is a program control device such as a CPU, and the storage unit 22 is a memory element such as ROM or RAM. The storage unit 22 may be, for example, a hard disk drive, and stores data such as programs executed by the processor 21. The communication unit 23 is a communication interface that conforms to wireless communication standards, similar to the communication unit 13. The display unit 24 is a display device such as a liquid crystal display or an organic EL display, and displays various images according to the instructions of the processor 21. The operation unit 25 is a user interface such as a touch sensor, keyboard, or mouse, which receives user input and outputs a signal indicating the content to the processor 21. The evaluation device 20 may also include video input / output terminals such as an HDMI (High Definition Multimedia Interface) (registered trademark) port, data input / output terminals such as a USB (Universal Serial Bus) port, and an optical disc drive for reading optical discs. In this embodiment, we will describe an example in which the evaluation device 20 is a tablet computer having a display (an example of a display unit 24) and an integrated touch sensor (an example of an operation unit 25). 【0016】 [3. Functional Configuration] Figure 3 is a functional block diagram showing an example of the functions implemented in the evaluation system 1. As shown in Figure 3, each of the multiple measuring devices 10 functionally includes an identification information acquisition unit 110, a speed calculation unit 120, a first display control unit 130, and a transmission unit 140. The evaluation device 20 functionally includes a condition data storage unit 210, a condition setting unit 220, a receiving unit 230, an evaluation information generation unit 240, and a second display control unit 250. The identification information acquisition unit 110, the speed calculation unit 120, the first display control unit 130, and the transmission unit 140 may be mainly implemented by the processor 11 of the measuring device 10. The condition data storage unit 210 may be implemented by the storage unit 22 of the evaluation device 20, and the condition setting unit 220, the receiving unit 230, the evaluation information generation unit 240, and the second display control unit 250 may be mainly implemented by the processor 21 of the evaluation device 20. In evaluation system 1, not all of the functions shown in Figure 3 are required to be implemented, and functions other than those shown in Figure 3 may be implemented. 【0017】 [3-1. Functions of the measuring device] Figure 4 is a schematic diagram showing an example of the use of the measuring device 10. In Figure 4, the batter 2, who is being measured, is shown from directly above as he swings his bat 3 forward (in the direction in which the measuring device 10 is positioned). A predetermined distance (for example, a distance of 1.5 meters or less) is provided between the measuring device 10 and the batter 2. The cover portion 19a of the measuring device 10 is oriented in the direction of the bat 3. That is, the antenna 16 of the measuring device 10 is oriented in the direction of the bat 3. In the example shown in Figure 4, the measuring device 10 may be attached to a support device (not shown). 【0018】 The speed calculation unit 120 of the measuring device 10 calculates the speed of the moving object (such as the tip of the bat 3 swung by the batter 2) based on the output from the Doppler sensor 17. The first display control unit 130 of the measuring device 10 then displays the speed information calculated by the speed calculation unit 120 on a display unit 14 or the like. This allows the measuring device 10 to measure the speed of the tip of the bat 3, which is the moving object, and display it on the display unit 14 or the like, all by itself. In the example shown in Figure 4, the display unit 14 displays the speed information as a numerical value of "103 km / h". The first display control unit 130 may also display information such as the number of times the speed has been measured along with the speed of the moving object. The first display control unit 130 may also display the speed information of the moving object on a display device such as a display connected via the video input / output terminal of the measuring device 10, or on a display device connected wirelessly via the communication unit 13. 【0019】 The Doppler sensor 17 generates a Doppler signal having a Doppler frequency based on the received signal supplied from the antenna 16 and outputs it to the velocity calculation unit 120. The velocity calculation unit 120 calculates the velocity of the moving object based on the Doppler frequency contained in the Doppler signal. The velocity of a moving object has the property that it is proportional to the Doppler frequency. Therefore, the velocity of the moving object can be calculated by substituting the Doppler frequency into a given calculation formula and performing the calculation. 【0020】 Figure 5 shows an example of how the speed calculation unit 120 calculates speed. For example, the direction of movement and speed of the tip of the bat 3 swung by the batter 2 differ depending on the position of the tip of the bat 3 during the period from the start to the end of the swing. As shown in Figure 5, the tip of the bat 3 moves in the direction of movement and at the speed indicated by arrows Va to Vf at each of the positions 3a to 3f. In the example shown in Figure 5, the speed of the tip of the bat 3 is indicated by the length of arrows Va to Vf. 【0021】 In velocity measurement using the antenna 16 and Doppler sensor 17, the velocity of the moving object in the direction that the antenna 16 is pointing is measured. In this embodiment, since the antenna 16 is pointed towards the rear of the measuring device 10 indicated by arrow D, at each position 3a to 3f shown in Figure 5, the velocity indicated by the length of arrows Va' to Vf', which are the directional components of arrows Va to Vf along the direction of arrow D (velocity reduced according to the angle between the direction of arrow D and the direction of movement) is measured. 【0022】 The speed calculation unit 120 calculates the maximum value of the moving speed of the moving object during a predetermined period based on the continuous output from the Doppler sensor 17 during that period. In the example shown in Figure 5, the direction of movement when the tip of the bat 3 is at 3d (the direction indicated by arrow Vd) coincides with the direction along arrow D, so the speed indicated by arrow Vd' is not reduced compared to the speed indicated by arrow Vd. For this reason, the speed calculation unit 120 calculates the speed indicated by the length of arrow Vd(Vd') as the moving speed of the tip of the bat 3. In other words, the speed calculation unit 120 calculates the speed of the moving object when it is moving along the direction that the antenna 16 is pointing. 【0023】 [3-2. Functions of the Evaluation System] [3-2-1. Example of use in simultaneous display mode] Figure 6A is a schematic diagram showing an example of using the evaluation system 1 in "simultaneous display mode". Figure 6A shows multiple batters 2A to 2C each swinging bats 3A to 3C (for example, practicing as a team). Each person being measured 2 is provided with a measuring device 10, and by swinging their bat towards the measuring device 10, speed information is displayed on the display unit 14 of the measuring device 10. This allows each batter to understand the speed of the bat they are swinging. 【0024】 In the example shown in Figure 6A, the evaluation device 20 receives speed information from multiple measuring devices 10 (10A to 10C) and displays the speed information measured by each of the multiple measuring devices 10 on the display unit 24. This allows the coach or manager of the baseball team, who is the user of the evaluation device 20, to understand the speed of each bat swing of multiple batters 2A to 2C. In the example shown in Figure 6A, the output shows that the speed measured by measuring device 10 (10A) "A" is "103 km / h", the speed measured by measuring device 10 (10B) "B" is "102 km / h", and the speed measured by measuring device 10 (10C) "C" is "106 km / h". 【0025】 The function shown in Figure 6A can be implemented, for example, as follows. First, the identification information acquisition unit 110 of the measuring device 10 acquires identification information to identify the measuring device 10. The identification information acquisition unit 110 may acquire information such as serial information and MAC (Media Access Control) address, which are pre-stored in the storage unit 12, as the identification information of the measuring device 10. Alternatively, the identification information acquisition unit 110 may acquire information unique to each of the multiple measuring devices 10 (information such as "A," "B," and "C" as shown in Figure 6B, which are assigned by the evaluation device 20) received from the evaluation device 20 via the communication unit 13, as the identification information of the measuring device 10. In this case, the first display control unit 130 may display the identification information acquired by the identification information acquisition unit 110 on the display unit 14. In this way, the user can understand the identification information assigned to the measuring device 10 by checking the display unit 14 of the measuring device 10. 【0026】 The condition data storage unit 210 of the evaluation device 20 stores condition data indicating conditions related to the measurement of a moving object using multiple measuring devices 10, and display conditions for the display unit 24, etc. The condition setting unit 220 sets the conditions related to the measurement of the moving object and the type of information to be displayed on the display unit 24 according to predetermined instruction information input by the user via the operation unit 25, etc. 【0027】 Figures 6B and 6C show examples of condition data stored in the condition data storage unit 210. The condition data storage unit 210 stores, for example, identification information of the measuring device 10 used for measuring a moving object, as shown in Figure 6B. In the example shown in Figure 6B, the identification information of measuring device 10A is "A", the identification information of measuring device 10B is "B", and the identification information of measuring device 10C is "C". When the identification information acquisition unit 110 of the measuring device 10 acquires information such as serial information and MAC address as identification information, and the transmission unit 140 transmits this information, the condition data storage unit 210 may store the serial information and MAC address in association with the identification information such as "A", "B", and "C" assigned on the evaluation device 20 side. The "placement location" information shown in Figure 6B will be described in detail in a later example. 【0028】 Furthermore, the condition data storage unit 210 stores information on display modes, such as the type of display content in the display unit 24, as condition data, for example, as shown in Figure 6C. In the example shown in Figure 6C, the information on multiple display modes in the display unit 24 includes "simultaneous display mode," "individual display mode," "evaluation mode (bat swing)," "evaluation mode (pitching)," and "evaluation mode (golf swing)." Each display mode's information is associated with a "selection flag," which is either "1" or "0." In the example shown in Figure 6C, "1" is associated with the selection flag for "simultaneous display mode," and "0" is associated with the information for the other display modes, indicating that the display in the display unit 24 will be set to "simultaneous display mode." The user of the evaluation system 1 can select one of the multiple display modes using the operation unit 25 of the evaluation device 20. The condition setting unit 220 sets the display mode in the display unit 24 by updating the value of the display mode selection flag shown in Figure 6C, for example. 【0029】 Furthermore, as shown in Figure 6C, the condition data storage unit 210 may store evaluation condition information associated with modes that output evaluation information, such as "evaluation mode (bat swing)", "evaluation mode (pitching)", and "evaluation mode (golf swing)". The condition setting unit 220 may update the evaluation condition information stored in the condition data storage unit 210 according to the user's input to the operation unit 25. "Evaluation condition information" refers to information such as "right-handed swing" or "left-handed swing" indicating how to hit a baseball or golf ball, or "left-handed throw" or "right-handed throw" indicating how to throw a baseball. Other examples of "evaluation condition information" include information such as "support device present" or "support device absent" indicating whether or not multiple measuring devices 10 used for measuring speed are attached to a dedicated support device (mounted member) such as a support device 81. 【0030】 The transmitter 140 of the measuring device 10 wirelessly transmits information on the speed of the moving object calculated by the speed calculation unit 120 to the evaluation device 20 via the communication unit 13. The receiver 230 of the evaluation device 20 then receives the information on the speed of the moving object from each of the multiple measuring devices 10 (10A to 10C). The transmitter 140 of the measuring device 10 may also wirelessly transmit the identification information acquired by the identification information acquisition unit 110 to the evaluation device 20 along with the speed information. In this case, the receiver 230 receives the identification information of the measuring device 10 that transmitted the information along with the information on the speed of the moving object. 【0031】 Figure 6D shows an example of information received by the receiving unit 230 of the evaluation device 20. In the example shown in Figure 6D, the receiving unit 230 receives speed information "113" along with identification information "A" from the measuring device 10A, speed information "102" along with identification information "B" from the measuring device 10B, and speed information "126" along with identification information "C" from the measuring device 10C. In addition, for example, if the transmitting unit 140 of the measuring device 10 transmits information such as the serial information or MAC address of the measuring device 10 as identification information, the receiving unit 230 may receive information such as the serial information or MAC address as the identification information of the measuring device 10 instead of information such as "A", "B", and "C". In this case as well, the condition data storage unit 210 stores identification information such as "A," "B," and "C" assigned by the evaluation device 20 in association with information such as serial information and MAC address, so that the second display control unit 250, which will be described later, can display the identification information such as "A," "B," and "C" on the display unit 24. 【0032】 As shown in Figure 5, the speed calculation unit 120 of the measuring device 10 calculates the maximum speed of the moving object. Therefore, the transmitting unit 140 of the measuring device 10 transmits the maximum speed calculated by the speed calculation unit 120 to the evaluation device 20, and the receiving unit 230 of the evaluation device 20 receives the maximum speed transmitted by the transmitting unit 140. The transmitting unit 140 may also transmit information such as the number of speed measurements to the evaluation device 20 along with the maximum speed. In this case, the receiving unit 230 may receive the information such as the number of measurements transmitted along with the maximum speed. 【0033】 The second display control unit 250 of the evaluation device 20 outputs the speed information received by the receiving unit 230 by displaying it on the display unit 24. In the example of "simultaneous display mode," the second display control unit 250 outputs the list of speed information shown in Figure 6A by displaying it on the display unit 24 or the like, based on the speed information received by the receiving unit 230 shown in Figure 6D. This allows coaches and managers, who are users of the evaluation device 20, to grasp the speed of the bat swings of batters 2A to 2C measured by each of the measuring devices 10A to 10C in a list. 【0034】 [3-2-2. Example of use in individual display mode] The user of the evaluation system 1 can switch the display mode on the display unit 24, etc., from "simultaneous display mode" to "individual display mode" using the operation unit 25, etc., of the evaluation device 20. The condition setting unit 220 sets the display mode on the display unit 24 to "individual display mode" by updating the selection flag associated with "individual display mode" in the condition data shown in Figure 6C from "0" to "1" in response to predetermined instruction information input by the user via the operation unit 25, etc. Furthermore, when "individual display mode" is set, the second display control unit 250 displays the speed information measured by one of the multiple measuring devices 10 (10A to 10C) on the display unit 24, etc. 【0035】 Figure 6E is a schematic diagram showing an example of the evaluation system 1 in "individual display mode". In "individual display mode", the second display control unit 250 displays the speed information measured by the measuring device 10A identified by the identification information, along with the identification information "A", on the display unit 24 or the like, as shown in Figure 6E. Here, the second display control unit 250 may also display information such as the number of measurements received by the receiving unit 230 from the measuring device 10A, along with the speed information measured by the measuring device 10A. 【0036】 Furthermore, the second display control unit 250 may switch the display on the display unit 24, etc., from the display of the speed measured by measuring device 10A, identified by the identification information "A", to the display of the speed measured by measuring device 10B or 10C, identified by the identification information "B" or "C", in accordance with predetermined instruction information indicating that a predetermined instruction has been given by the user via the operation unit 25, etc. This allows the coach or manager, who is the user of the evaluation device 20, to focus on one of the batters 2A to 2C and grasp information such as the speed of that person's bat swing. 【0037】 [3-2-3. Example of use in evaluation mode (bat swing)] Figure 7A is a schematic diagram showing an example of the use of the evaluation system 1 in "evaluation mode (bat swing)". In various evaluation modes, multiple measuring devices 10 (10A to 10C) are used to measure the speed of the moving object (in the example shown in Figure 7A, the speed of the tip of the bat 3 swung by batter 2). The evaluation device 20 then outputs evaluation information regarding the movement of the moving object based on the speed information measured by the multiple measuring devices 10 by displaying it on a display unit 24 or the like. 【0038】 The second display control unit 250 outputs either the information shown in Figure 6A, which represents each of the multiple movement speeds received by the receiving unit 230, or the evaluation information shown in Figure 7A, etc., according to predetermined instruction information. The condition setting unit 220 updates the selection flag associated with "evaluation mode (bat swing)" in the condition data shown in Figure 6C from "0" to "1" according to predetermined instruction information input by the user via the operation unit 25, etc., thereby setting the display content on the display unit 24, etc. to "evaluation mode (bat swing)". 【0039】 In the example shown in Figure 7A, the evaluation information includes an image 24a of the moving object showing its position or orientation when the moving object is moving at its maximum speed, and an image 24b of an arrow or similar showing the direction of movement of the moving object at that time. In addition, information such as "CENTER" indicating that the direction of movement of the tip of the moving object, bat 3, is towards the center, and "INSIDE" or "OUTSIDE" indicating that the direction of movement is to the right or left relative to the center, are output. Furthermore, in the example shown in Figure 7A, numerical information such as "3.4°" indicating the angle of the direction of movement relative to the center is output as evaluation information. 【0040】 Figure 7B shows an example of condition data stored in the condition data storage unit 210, and shows the condition data when "evaluation mode (bat swing)" is set. The condition data storage unit 210 stores information indicating the position of the measuring device 10 relative to the moving body, associated with the identification information of the measuring device 10, as shown in Figure 7B, for example. In the example shown in Figures 7A and 7B, the information "front left," indicating that the measuring device 10A is positioned to the front left of the tip of the moving body, the bat 3, is stored associated with the identification information "A." In addition, the information "front center," indicating that the measuring device 10B is positioned in the front center from the bat 3, is stored associated with the identification information "B," and the information "front right," indicating that the measuring device 10C is positioned to the front right from the bat 3, is stored associated with the identification information "C." 【0041】 In the evaluation mode shown in Figure 7A, etc., the evaluation information generation unit 240 of the evaluation device 20 generates evaluation information regarding the movement of a moving object based on multiple pieces of moving speed information received by the receiving unit 230 from multiple measuring devices 10A to 10C. In this case, the second display control unit 250 of the evaluation device 20 functions as an evaluation information output unit that outputs the evaluation information generated by the evaluation information generation unit 240. 【0042】 Figure 7C is a diagram illustrating an example of how the evaluation information generation unit 240 generates evaluation information. As shown in Figures 7A to 7C, the multiple measuring devices 10A to 10C are arranged in multiple directions relative to the moving body. Measuring device 10A is positioned to the front left of the tip of the moving body, the bat 3; measuring device 10B is positioned in the front center of the tip of the bat 3; and measuring device 10C is positioned to the front right of the tip of the bat 3. Here, the cover portion 19a (antenna 16) of each measuring device 10 is facing the direction of the bat 3. The cover portion 19a of measuring device 10A is facing in the direction indicated by arrow Da (right rearward); the cover portion 19a of measuring device 10B is facing in the direction indicated by arrow Db (rearward); and the cover portion 19a of measuring device 10C is facing in the direction indicated by arrow Dc (left rearward). The evaluation information generation unit 240 can determine the placement position and orientation of each measuring device 10 based on the information on the placement position of each measuring device 10 stored in the condition data storage unit 210 (see Figure 7B). 【0043】 As mentioned above, the speed calculation unit 120 of each measuring device 10 calculates the maximum value of the moving speed of the moving object. Therefore, the speed calculation unit 120 of each measuring device 10 calculates the speed when the moving object is moving along the direction that the antenna 16 of that measuring device 10 is pointing. In the example shown in Figure 7C, the speed calculation unit 120 of measuring device 10A calculates the speed when the tip of the bat 3 is moving in the direction along the direction of arrow Da that measuring device 10A is pointing (the direction indicated by arrow Vi) (the speed when the tip of the bat 3 is at position 3i, indicated by the length of arrow Vi). Similarly, the speed calculation units 120 of measuring devices 10B and 10C calculate the speed when the tip of the bat 3 is moving in the directions along the directions of arrows Db and Dc that measuring devices 10B and 10C are pointing to, respectively (the directions indicated by arrows Vh and Vg) (the speed when the tip of the bat 3 is at positions 3h and 3g). In the following explanation, the velocities indicated by the lengths of the arrows Vg, Vh, and Vi may sometimes simply be referred to as velocities Vg, Vh, and Vi. 【0044】 The transmitting unit 140 of each measuring device 10 transmits the maximum value of the moving speed calculated by the speed calculation unit 120 to the evaluation device 20. The receiving unit 230 of the evaluation device 20 receives the maximum values ​​of multiple moving speeds transmitted from the transmitting unit 140 of each measuring device 10. In the example shown in Figure 7C, the receiving unit 230 receives information indicating the speed Vi when the tip of the bat 3 is at position 3i, information indicating the speed Vg when the tip of the bat 3 is at position 3h, and information indicating the speed Vg when the tip of the bat 3 is at position 3g. 【0045】 The evaluation information generation unit 240 of the evaluation device 20 generates evaluation information based on a comparison of the maximum values ​​of multiple moving speeds received by the receiving unit 230, and the second display control unit 250 (evaluation information output unit) outputs the evaluation information generated by the evaluation information generation unit 240 by displaying it on the display unit 24 or the like. In the example of Figure 7C, the evaluation information generation unit 240 generates evaluation information based on a comparison of the speed Vi (speed measured by the measuring device 10A) when the tip of the bat 3 is at 3i, the speed Vh (speed measured by the measuring device 10B) when the tip of the bat 3 is at 3h, and the speed Vg (speed measured by the measuring device 10C) when the tip of the bat 3 is at 3g. 【0046】 The second display control unit 250 (evaluation information output unit) outputs evaluation information, for example, information on the direction of movement of the moving object. More specifically, the second display control unit 250 outputs evaluation information, for example, information on the direction of movement of the moving object at the position of the moving object when the moving object's speed is at its maximum. 【0047】 In the example shown in Figure 7C, the evaluation information generation unit 240 generates evaluation information indicating the direction of movement at position 3h when the moving speed of the tip of the bat 3 is at its maximum speed Vh, based on the speed information received by the receiving unit 230 from the measuring devices 10A to 10C. This is done when the speed Vh measured by the measuring device 10B is greater than the speeds Vi and Vg measured by the measuring devices 10A and 10C, and the speed difference or speed ratio between speed Vi and speed Vg is within a predetermined threshold. In this case, the evaluation information generation unit 240 determines that the tip of the bat 3 is moving towards the center and generates evaluation information indicating that the direction of movement is towards the center. The second display control unit 250 then outputs information such as "CENTER" along with an image 24b such as an arrow indicating that the direction of movement of the tip of the bat 3 is towards the center, by displaying it on the display unit 24 or the like. 【0048】 Furthermore, if the evaluation information generation unit 240 determines that the velocity Vi measured by the measuring device 10A is greater than the velocities Vh and Vg measured by the measuring devices 10B and 10C, it determines that the tip of the bat 3 is moving to the left relative to the center and generates evaluation information indicating that the direction of movement is to the left (i.e., evaluation information indicating the direction of movement at position 3i when the moving velocity of the tip of the bat 3 is the maximum velocity Vi). Similarly, if the evaluation information generation unit 240 determines that the velocity Vg measured by the measuring device 10C is greater than the velocities Vi and Vh measured by the measuring devices 10A and 10B, it determines that the tip of the bat 3 is moving to the right relative to the center and generates evaluation information indicating that the direction of movement is to the right (evaluation information indicating the direction of movement at position 3g when the moving velocity of the tip of the bat 3 is the maximum velocity Vg). 【0049】 The second display control unit 250 outputs evaluation information based on the evaluation condition information stored in the condition data storage unit 210. In the example shown in Figure 6C, the condition data storage unit 210 stores evaluation condition information indicating that the batting style is "right-handed" in association with the "evaluation mode (bat swing)". Here, if the evaluation information generation unit 240 generates evaluation information indicating that the direction of movement of the tip of the bat 3 is to the left, the second display control unit 250 outputs this information by displaying it on the display unit 24 or the like, along with an image 24b such as an arrow indicating that the direction of movement of the tip of the bat 3 is to the left, as shown in Figure 7A, and information such as "INSIDE" indicating that the direction of movement of the bat 3 is inward. 【0050】 Furthermore, if evaluation information is generated indicating that the batting style is "right-handed" and the direction of movement of the tip of the bat 3 is to the right, the second display control unit 250 outputs "OUTSIDE" information indicating that the direction of movement of the bat 3 is to the outside, along with an image 24b such as an arrow indicating that the direction of movement of the tip of the bat 3 is to the right. Similarly, if evaluation information is generated indicating that the batting style is "left-handed" and the direction of movement of the tip of the bat 3 is to the left, the second display control unit 250 outputs "OUTSIDE" information as the direction of movement, and if evaluation information is generated indicating that the batting style is "left-handed" and the direction of movement of the tip of the bat 3 is to the right, the second display control unit 250 outputs "INSIDE" information as the direction of movement. 【0051】 The second display control unit 250 may output evaluation information, including information indicating the position or orientation of the moving body when its movement speed is at its maximum, by displaying it on the display unit 24 or the like. In the example shown in Figures 7A and 7B, an image 24a showing the orientation of the bat 3 when the movement speed of the tip of the bat 3 is at its maximum speed Vi is output. In image 24a, the tip of the bat 3 is located in front of the grip portion of the bat 3, indicating that the tip of the bat 3 is at position Vi. 【0052】 The second display control unit 250 may output information on the angle of the direction of movement of the moving body by displaying it on the display unit 24 or the like when the arrangement of the multiple measuring devices 10 satisfies predetermined conditions. The angle of the direction of movement of the moving body with respect to the central direction in front of the moving body is proportional to the speed difference or speed ratio of the speeds measured by each of the multiple measuring devices 10. Therefore, the evaluation information generation unit 240 can calculate the angle of the direction of movement by substituting the speed difference or speed ratio of the speeds measured by each measuring device 10 into a predetermined correlation formula, provided that the multiple measuring devices 10 are arranged such that their positions and orientations relative to the moving body are predetermined. In the example in Figures 7A to 7C, the multiple measuring devices 10 (10A to 10C) are attached to a dedicated support device 81. In the support device 81, the multiple measuring devices 10 are arranged in the left-right direction, and a predetermined interval is provided between each measuring device 10. Furthermore, each measuring device 10 is attached to the support device 81 so as to face the tip of the moving body, the bat 3, in a predetermined angular direction. 【0053】 In the example shown in Figure 6C, the condition data storage unit 210 stores "support device present" information as evaluation condition information, associated with "evaluation mode (bat swing)," indicating that multiple measuring devices 10 (10A to 10C) are attached to a dedicated support device 81. In this case, the evaluation information generation unit 240 may calculate the angle of the direction of movement of the moving body relative to the center direction based on the speed difference or speed ratio of velocities Vi and Vg measured by measuring devices 10A and 10C. Alternatively, the evaluation information generation unit 240 may calculate the angle of the direction of movement of the moving body relative to the center direction based on the speed difference or speed ratio of velocities Vi and Vh measured by measuring devices 10A and 10B, and the speed difference or speed ratio of velocities Vh and Vg measured by measuring devices 10B and 10C. In this way, the evaluation information generation unit 240 generates evaluation information including information about the angle of the direction of movement of the moving object, and the second display control unit 250 outputs the evaluation information including the angle information by displaying it on the display unit 24 or the like, as shown in Figure 7A. 【0054】 Figure 7D is a schematic diagram showing another example of the use of the evaluation system 1 in "evaluation mode (bat swing)". In the example shown in Figure 7D, unlike the example shown in Figure 7A, the multiple measuring devices 10 (10A~10C) that measure the speed of the tip of the moving bat 3 are not attached to the dedicated support device 81, but are placed at arbitrary positions such as the batter 2, coach, or manager. In such a case, even if the angle of the direction of movement of the moving body is calculated based on the speed difference or speed ratio of the speeds measured by each measuring device 10, there is a possibility that the difference from the actual angle will be large. 【0055】 The second display control unit 250 may output either first evaluation information, which is evaluation information when the multiple measuring devices 10 are attached to the support device 81, or second evaluation information, which is evaluation information when the multiple measuring devices 10 are not attached to the support device 81, according to predetermined instruction information. As shown in Figure 7D, if the multiple measuring devices 10 (10A to 10C) are not attached to the support device 81, for example, the condition setting unit 220 sets the information "No support device" indicating that the multiple measuring devices 10 are not attached to the support device 81, according to predetermined instruction information input by the user via the operation unit 25 or the like. In this case, the condition data storage unit 210 stores the information "No support device" as evaluation condition information, associated with "Evaluation mode (bat swing)". 【0056】 The evaluation information generation unit 240 generates evaluation information that does not include information about the angle of movement of the moving body, based on the evaluation condition information stored in the condition data storage unit 210, when the information "no support device" is set. Then, as shown in Figure 7D, the second display control unit 250 outputs the evaluation information that does not include angle information by displaying it on the display unit 24 or the like. In this way, when multiple measuring devices 10 are not attached to a dedicated support device such as the support device 81, outputting evaluation information that does not include angle information improves the reliability of the information output to the display unit 24 or the like. 【0057】 Furthermore, the evaluation information generation unit 240 may generate evaluation information regarding the movement of the tip of the bat 3 based on the direction of movement of the tip of the bat 3 measured by means other than the multiple measuring devices 10, similar to the example of a golf swing described later. The evaluation information generation unit 240 may calculate the angle of the direction of movement based on an image, such as a video captured by a camera. In this case, the evaluation information generation unit 240 can calculate information about the direction of movement, such as the angle, by creating a correlation formula in advance between the angle of the direction of movement of the tip of the bat 3 based on an image captured by a camera and the speed difference or speed ratio of the speeds measured by the multiple measuring devices 10. 【0058】 Furthermore, the evaluation information generation unit 240 may generate evaluation information regarding the movement of the tip portion of the bat 3 based on information derived from the output of sensors such as inertial sensors attached to the bat 3. In this case, the evaluation information generation unit 240 can calculate information on the direction of movement, such as angle, by pre-creating a correlation formula between the output from the sensor and the speed difference or speed ratio of the speeds measured by the multiple measuring devices 10. In this way, by calculating information on the direction of movement, such as angle, based on information measured by means other than the multiple measuring devices 10, it becomes possible to calculate more accurate information on the direction of movement, such as angle. 【0059】 [3-2-4. Example of use in evaluation mode (pitching)] Figure 8 is a schematic diagram showing an example of the use of evaluation system 1 in "evaluation mode (pitching)". In the example shown in Figure 8, a support device 82 is placed near the pitcher 2D, who is being measured, and a measuring device 10D is attached to it. Also, a support device 83 is placed near the catcher 2E, who catches the ball 4 thrown by pitcher 2D, and a measuring device 10E is attached to it. The measuring device 10D measures the initial velocity of the ball 4 as it is thrown by pitcher 2D. The measuring device 10E measures the final velocity of the ball 4 when it is caught by catcher 2E. 【0060】 Each transmitting unit 140 of measuring devices 10D and 10E transmits information on the speed of the ball 4 (maximum speed) calculated by the speed calculation unit 120 based on the output from the Doppler sensor 17 of the measuring device 10 to the evaluation device 20. The evaluation information generation unit 240 of the evaluation device 20 generates evaluation information regarding the movement of the moving object based on the multiple moving speed information received by the receiving unit 230 from the multiple measuring devices 10D and 10E, and the second display control unit 250 (evaluation information output unit) outputs the evaluation information generated by the evaluation information generation unit 240. 【0061】 The evaluation information generation unit 240 generates evaluation information based on a comparison of the maximum values ​​of multiple moving speeds received by the receiving unit 230. In the example shown in Figure 8, evaluation information including the speed reduction rate is generated based on a comparison of the initial speed of the ball 4, indicated by the speed information received from the measuring device 10D, and the final speed of the ball 4, indicated by the speed information received from the measuring device 10E. The second display control unit 250 then outputs the evaluation information, including the numerical information of the reduction rate, by displaying it on the display unit 24 or the like, as shown in Figure 8. The evaluation information generation unit 240 may determine whether the speeds received from the measuring devices 10 and 10E are the initial speed or the final speed based on the information of the placement positions of the measuring devices 10D and 10E stored in the condition data storage unit 210, or it may determine the larger of the speeds received from the measuring devices 10D and 10E as the initial speed. 【0062】 The second display control unit 250 may output evaluation information that includes information indicating the quality of the movement of the moving object. In the example shown in Figure 8, the second display control unit 250 outputs evaluation information such as "excellent," "great," and "good" to indicate that the throw of ball 4 was good, or evaluation information such as "average" to indicate that the throw of ball 4 was not good, based on whether the deceleration rate calculated based on the initial velocity and speed of ball 4 measured by measuring devices 10D and 10E falls within a predetermined numerical range. Depending on which of the multiple stepwise numerical ranges the calculated deceleration rate falls within, the second display control unit 250 may output evaluation information indicating which of the multiple evaluation levels (for example, one of the five evaluation levels) the throw of ball 4 is rated on. 【0063】 [3-2-5. Example of use in evaluation mode (golf swing)] Figure 9 is a schematic diagram showing an example of the evaluation system 1 in "evaluation mode (golf swing)". In the example shown in Figure 9, the speed of the club head 5 of the golf club swung by the person being measured is measured using multiple measuring devices 10 (10F~10H). In the example shown in Figure 9, similar to the "evaluation mode (bat swing)" example shown in Figures 7A~7C, the multiple measuring devices 10 are attached to a dedicated support device 84. The support device 84 has a metal plate with holes, similar to the support device 81, and the position and orientation of each measuring device 10 are determined by attaching the multiple measuring devices 10 to this support device 84 with screws or the like. In the example shown in Figure 9, the multiple measuring devices 10 attached to the support device 84 are placed behind the club head 5. 【0064】 Each measuring device 10 is mounted on a support device 84 such that its built-in antenna 16 faces the moving club head 5 at a predetermined angle. The antenna 16 of measuring device 10A is pointed diagonally forward to the right, indicated by arrow Df; the antenna 16 of measuring device 10B is pointed towards the front center, indicated by arrow Dg; and the antenna 16 of measuring device 10C is pointed diagonally forward to the left, indicated by arrow Dh. 【0065】 In the example shown in Figure 9, each transmitting unit 140 of the multiple measuring devices 10 (10F to 10H) transmits information on the speed of the club head 5 (maximum speed) calculated by the speed calculation unit 120 based on the output from the Doppler sensor 17 of the measuring device 10 to the evaluation device 20. The evaluation information generation unit 240 of the evaluation device 20 generates evaluation information regarding the movement of the club head 5 based on the multiple movement speed information received by the receiving unit 230 from the multiple measuring devices 10, and the second display control unit 250 (evaluation information output unit) outputs the evaluation information generated by the evaluation information generation unit 240. 【0066】 In the example shown in Figure 9, the evaluation information generation unit 240 generates evaluation information based on the speed information received by the receiving unit 230 from the measuring devices 10F to 10H. For example, if the speed in the direction along arrow Dg measured by measuring device 10G is greater than the speeds in the directions along arrows Df and Dh measured by measuring devices 10F and 10H, and the speed difference or speed ratio of the speeds measured by measuring devices 10F and 10H is within a predetermined threshold, the evaluation information generation unit 240 generates evaluation information indicating that the direction of movement of the club head 5 is towards the center. In this case, the second display control unit 250 outputs information such as "STRAIGHT" indicating that the direction of movement of the club head 5 is towards the center by displaying it on the display unit 24 or the like, along with an image 24a of the club head 5 and an image 24b of an arrow indicating its direction of movement. 【0067】 Furthermore, in the example shown in Figure 9, if the evaluation information generation unit 240 determines that the speed in the direction along arrow Df measured by measuring device 10F is greater than the speed measured by measuring devices 10G and 10H, it determines that the direction of movement of the club head 5 is to the right and generates evaluation information indicating that the direction of movement is to the right. Similarly, if the evaluation information generation unit 240 determines that the speed in the direction along arrow Dh measured by measuring device 10H is greater than the speed measured by measuring devices 10F and 10G, it determines that the direction of movement of the club head 5 is to the left and generates evaluation information indicating that the direction of movement is to the left. 【0068】 In the condition data shown in Figure 6C, the evaluation condition information indicating that the swing is "right-handed" is associated with the "evaluation mode (golf swing)". If it is determined that the direction of movement of the club head 5 is to the right, the second display control unit 250 outputs information such as "INSIDE OUT" on the display unit 24, indicating that the direction of movement of the club head 5 was from outside to inside relative to the person swinging the golf club. Furthermore, if it is determined that the swing is "right-handed" and the direction of movement of the club head 5 is to the left, the second display control unit 250 outputs "OUTSIDE IN" information indicating that the direction of movement of the club head 5 was from inside to outside. 【0069】 In the example shown in Figure 9, the second display control unit 250 outputs evaluation information, including information indicating the quality of the movement of the club head 5, which is a moving object, by displaying it on the display unit 24. The evaluation information generation unit 240 determines the direction of movement of the club head 5 based on the speed difference or speed ratio of the club head 5 measured by a plurality of measuring devices 10 (10F to 10H). Then, based on the determined direction of movement, it generates evaluation information, including information indicating the quality of the movement of the club head 5 (i.e., the swing of the golf club). The second display control unit 250 outputs evaluation information such as "excellent" indicating the quality of the movement of the club head 5 by displaying it on the display unit 24. 【0070】 In a golf swing, an ideal swing is one in which the club head 5 does not move outward or inward relative to the person swinging the golf club, and the direction of movement of the club head 5 is towards the center. For this reason, the second display control unit 250 may output information such as "excellent," "great," or "good" to indicate that the movement of the club head 5 (i.e., the golf club swing by the person being measured) was good, when the evaluation information generation unit 240 determines that the direction of movement of the club head 5 is towards the center. The second display control unit 250 may also output information such as "average" to indicate that the movement of the club head 5 was not good, when the direction of movement of the club head 5 is determined to be to the right or to the left. 【0071】 In the example shown in Figure 9, when multiple measuring devices 10 are attached to a single support device 82 (i.e., when multiple measuring devices 10 are arranged such that their positions and orientations are predetermined), the second display control unit 250 may output evaluation information including information on the angle of the club head 5's direction of movement. In this case, the evaluation information generation unit 240 may calculate the angle of the club head 5's direction of movement relative to the center based on the speed difference or speed ratio of the speeds of the club head 5 measured by measuring devices 10F and 10H. Alternatively, the evaluation information generation unit 240 may calculate the angle of the club head 5's direction of movement relative to the center based on the speed difference or speed ratio of the speeds measured by measuring devices 10F and 10G and the speed difference or speed ratio of the speeds measured by measuring devices 10G and 10H. The evaluation information generation unit 240 may calculate the angle of the direction of movement by substituting the speed difference or speed ratio of the speeds measured by measuring device 10 into a predetermined correlation formula. Furthermore, the evaluation information generation unit 240 may generate evaluation information that includes information indicating the quality of the movement of the club head 5 based on the angle calculated in this way. The second display control unit 250 may output information indicating one of a plurality of stepwise evaluations corresponding to the angle of the club head 5's movement direction to the display unit 24 or the like. 【0072】 The evaluation information generation unit 240 may generate evaluation information regarding the movement of the club head 5 based on speed information measured by multiple measuring devices 10 and the direction of movement of the club head 5 measured by means other than the multiple measuring devices 10. In the example shown in Figure 9, a camera 90 is provided above the head of the person being measured who is swinging a golf club. The camera 90 has a lens 91, which is used to photograph the movement of the club head 5. The evaluation information generation unit 240 may calculate the angle of the direction of movement of the club head 5 based on images such as a video taken by the camera 90. The evaluation information generation unit 240 may then generate evaluation information including information regarding the direction of movement of the club head 5, such as the angle relative to the center, based on the speed difference or speed ratio of the speeds measured by multiple measuring devices 10 and the angle of the direction of movement of the club head 5 based on the images taken by the camera 90. The evaluation information generation unit 240 can calculate information about the direction of movement, such as the angle, by, for example, pre-creating a correlation formula between the speed difference or speed ratio of speeds measured by multiple measuring devices 10 and the angle of the direction of movement of the club head 5 based on the image captured by the camera 90. 【0073】 The evaluation information generation unit 240 may generate evaluation information including the direction of movement, such as angle, not only from images captured by the camera 90, but also by using acceleration sensors provided on the golf club or club head 5, and pre-creating a correlation formula between information based on the output from those sensors and the speed difference or speed ratio of the speeds measured by the multiple measuring devices 10. In this way, by generating evaluation information including the direction of movement, such as angle, based on the direction of movement of the club head 5 measured by means other than the multiple measuring devices 10, the second display control unit 250 can output more accurate information on the direction of movement, such as angle, to the display unit 24 or the like. 【0074】 [4. Flowchart] Figure 10 shows an example of the processing flow performed by the evaluation device 20. First, the receiving unit 230 of the evaluation device 20 receives information on the speed of the moving object from each of the multiple measuring devices 10 that measured the speed of the moving object (step S101). In step S101, the receiving unit 230 receives, for example, the maximum value of the speed measured by each of the multiple measuring devices 10. In step S101, the receiving unit 230 may also receive information such as unique identification information to identify each measuring device 10 and the number of measurements taken. 【0075】 Next, the second display control unit 250 of the evaluation device 20 determines which of the multiple display modes is selected in the condition data stored in the condition data storage unit 210 (step S102). For example, the second display control unit 250 of the evaluation device 20 determines which of the following information has a selection flag set to "1": "simultaneous display mode", "individual display mode", "evaluation mode (bat swing)", "evaluation mode (pitching)", and "evaluation mode (golf swing)" as shown in Figure 6C. 【0076】 If the second display control unit 250 determines in step S102 that the "simultaneous display mode" is selected, it outputs a list of speed information measured by the multiple measuring devices 10 (step 103). In step S103, the second display control unit 250 outputs a list of speeds measured by the measuring devices 10 identified by each piece of identification information, along with multiple pieces of identification information such as "A", "B", and "C", as shown in Figure 6A, by displaying it on the display unit 24 or the like. 【0077】 If the second display control unit 250 determines in step S102 that the "individual display mode" has been selected, it outputs individual speed information measured by one of the multiple measuring devices 10 (step S104). In step S104, the second display control unit 250 outputs the speed information measured by the measuring device 10 identified by the identification information, along with identification information such as "A", on the display unit 24, for example, as shown in Figure 6E. In step S104, the second display control unit 250 may also output information such as the number of measurements received by the receiving unit 230 in step S101, along with the speed information. Furthermore, the second display control unit 250 may switch from displaying the speed measured by the measuring device 10 identified by the identification information "A" to displaying the speed measured by the measuring device 10 identified by other identification information such as "B" or "C", in response to predetermined instruction information indicating that a predetermined instruction has been given by the user via the operation unit 25 or the like. 【0078】 If it is determined in step S102 that "Evaluation Mode (Bat Swing)", "Evaluation Mode (Pitching)", or "Evaluation Mode (Golf Swing)" has been selected, the second display control unit 250 executes the evaluation information output process shown in Figure 11 (step S105). 【0079】 Figure 11 shows an example of the evaluation information output process in step S105. As shown in Figure 11, the second display control unit 250 determines which type of evaluation mode is being used (step S201). In the example shown in Figure 11, it determines whether the evaluation mode is a bat swing, a pitching swing, or a golf swing. 【0080】 If the type of evaluation mode is determined to be pitching in step S201, the evaluation information generation unit 240 calculates the deceleration rate based on the speed difference or speed ratio of the multiple speeds received in step S101 (step S202). In step S202, the evaluation information generation unit 240 generates evaluation information including the deceleration rate based on the speed difference or speed ratio between the initial velocity of the ball 4 measured by the measuring device 10D located near the pitcher 2D and the final velocity of the ball 4 measured by the measuring device 10E located near the catcher 2E, for example, as shown in Figure 8. 【0081】 Next, the second display control unit 250 outputs evaluation information, including the numerical information of the deceleration rate calculated in step S202, by displaying it on the display unit 24 or the like (step S203), and terminates the process. In step S204, the second display control unit 250 may output information such as "excellent" indicating the quality of the movement of the ball 4, along with the deceleration rate. 【0082】 If, in step S201, it is determined that the type of evaluation mode is a bat swing or a golf swing, the evaluation information generation unit 240 determines the direction of movement of the moving body based on the speed difference or speed ratio of the multiple speeds received in step S101 (step S204). In step S204, for example, if, among a plurality of measuring devices 10 arranged in the left-right direction in front of or toward the tip of the bat 3 or the club head 5 of the golf club, the speed measured by the measuring device 10 located in the center is greater than the speeds measured by the measuring devices 10 located on the right and left sides, respectively, and the speed difference or speed ratio measured by the measuring device 10 on the right and left sides is within a predetermined threshold, the evaluation information generation unit 240 determines that the direction of movement of the moving body is towards the center, either forward or backward. Also, if the speed measured by the measuring device 10 on the right or left side is greater than the speed measured by the other measuring devices, the evaluation information generation unit 240 determines that the direction of movement of the moving body is to the right or left relative to the center. 【0083】 Next, the evaluation information generation unit 240 determines whether information such as "support device present" is set in the condition data stored in the condition data storage unit 210, in association with the evaluation mode information determined in step S102 (step S205). If it is determined in step S205 that the information "support device present" is set, the evaluation information generation unit 240 calculates the angle of the direction of movement based on the speed difference or speed ratio of the multiple speeds received in step S101 (step S206). In step S206, the evaluation information generation unit 240 may, for example, calculate the angle of the direction of movement relative to the center in the forward or backward direction by substituting the speed difference or speed ratio of the multiple speeds received in step S101 into a predetermined correlation formula. 【0084】 Furthermore, in step S206, if the condition data stored in the condition data storage unit 210 contains information indicating that the direction of movement of the moving body is measured by other means in relation to the evaluation mode information determined in step S102, the evaluation information generation unit 240 may calculate the angle of the direction of movement based on the direction of movement of the moving body measured by other means and the speed difference or speed ratio of the multiple speeds received in step S101. For example, the evaluation information generation unit 240 calculates the angle of the direction of movement by substituting information such as the angle indicating the direction of movement of the moving body measured by other means and the speed difference or speed ratio of the multiple speeds received in step S101 into a predetermined correlation formula. 【0085】 Next, the second display control unit 250 outputs evaluation information, including the information on the direction of movement determined in step S204, by displaying it on the display unit 24 or the like (step S207), and terminates the process. If, in step S204, it is determined that the direction of movement of the moving object is the central direction, either forward or backward, then in step S207, the second display control unit 250 generates evaluation information, including information indicating that the direction of movement is the central direction, such as "CENTER" or "STRAIGHT". 【0086】 Furthermore, in step S204, if it is determined that the direction of movement of the moving body is to the right or to the left, the second display control unit 250, in step S207, outputs information such as "INSIDE" or "OUTSIDE IN" to the person being measured, indicating that the direction of movement of the moving body was inward, or information such as "OUTSIDE" or "INSIDE OUT" to the person being measured, based on the condition data stored in the condition data storage unit 210, which is stored in association with the evaluation mode information determined in step S102. The second display control unit 250 outputs information such as "OUTSIDE" or "INSIDE OUT" to indicate that the direction of movement of the moving body was outward if the direction indicated by the information on the hitting method, such as "hitting to the right" or "hitting to the left," matches the direction of movement of the moving body determined in step S204. If the direction indicated by the information on the hitting method does not match the direction of movement of the moving body, it outputs information such as "INSIDE" or "OUTSIDE IN" to indicate that the direction of movement of the moving body was inward. 【0087】 In step S206, if the angle of the direction of movement of the moving object is calculated, in step S207, the second display control unit 250 outputs evaluation information including numerical information indicating that angle. In this case, the second display control unit 250 may output information such as "excellent" indicating the quality of the movement of the moving object, along with velocity information, based on the angle calculated in step S206. Alternatively, in step S207, the second display control unit 250 may output information indicating the quality of the movement of the moving object, based on the direction of movement determined in step S204. For example, if the direction determined in step S204 is the central direction, the second display control unit 250 may output information indicating that the movement of the moving object was good, along with information such as "CENTER" or "STRAIGHT". 【0088】 [5. Summary] As described above, the evaluation system 1 has a plurality of measuring devices 10 and an evaluation device 20. Each of the plurality of measuring devices 10 includes a speed calculation unit 120 that calculates the speed of a moving object such as the tip of the bat 3, the ball 4, or the club head 5 based on the output from the Doppler sensor 17, a first display control unit 130 that displays the speed information calculated by the speed calculation unit 120 on a display unit 14 or the like, and a transmission unit 140 that wirelessly transmits the speed information calculated by the speed calculation unit 120 to the evaluation device 20. The evaluation device 20 includes a receiving unit 230 that receives speed information from each of the plurality of measuring devices 10, and a second display control unit 250 (evaluation information output unit) that outputs evaluation information regarding the movement of a moving object by displaying it on a display unit 24 or the like based on the plurality of speed information received by the receiving unit 230. According to this, by using a measuring device 10 that can independently measure and control the speed of a moving object, it becomes possible to appropriately evaluate the movement of a moving object according to the type of moving object, such as the tip of the bat 3, the ball 4, or the club head 5, and the evaluation content such as the direction of movement and the deceleration rate of the moving object. 【0089】 [6. Variant] The present invention is not limited to the embodiments described above. 【0090】 (1) In the embodiment, the support devices 81 and 84 have metal plates extending in the left-right direction, and an example was described in which a plurality of measuring devices 10 are attached to these metal plates by screws or the like. The mounting member to which the plurality of measuring devices 10 are attached is not limited to this, and any member that determines the position and orientation of each measuring device 10 relative to the moving body is acceptable. 【0091】 Figure 12 shows an example of a mounting member to which multiple measuring devices 10 are attached. The mounting member 89 shown in Figure 12 has an upper surface 89a that is large enough to encompass multiple measuring devices 10 arranged in the left-right direction. Multiple guide portions 89b corresponding to the shape and size of the measuring devices 10 are provided on the upper surface 89a. The guide portions 89b may be, for example, illustrations showing the outline of the measuring device 10, or they may be recesses that are indented downward in an area along the outline of the measuring device 10. By arranging the measuring devices 10 on the guide portions 89b of such a mounting member 89, the position and orientation of the measuring devices 10 relative to the moving body can be determined. 【0092】 Furthermore, the orientation in which the multiple measuring devices 10 are arranged is not limited to the left-right direction, but may also be in the front-back direction, the up-down direction, or diagonally thereto. For example, by arranging the multiple measuring devices 10 in the up-down direction, it becomes possible to output appropriate evaluation information regarding the movement of a moving object that moves in the up-down direction. 【0093】 Furthermore, the orientation in which the multiple measuring devices 10 are arranged is not limited to one; the multiple measuring devices 10 may be arranged in two or more directions. For example, at least two measuring devices 10 may be arranged in the left-right direction, and at least two measuring devices 10 may be arranged in the up-down direction. In this way, it becomes possible to obtain evaluation information regarding the movement of the moving body in the left-right direction and evaluation information regarding the movement in the up-down direction simultaneously. 【0094】 (2) In this embodiment, the transmitting units 140 of a plurality of measuring devices 10 transmit identification information along with speed information to the evaluation device 20, and the evaluation information generation unit 240 of the evaluation device 20 identifies the placement position and orientation of each measuring device 10 based on the placement position information associated with the identification information of each measuring device 10 (information showing the relative placement and orientation to the moving object, as shown in Figure 7B) in the condition data stored in the condition data storage unit 210. However, the embodiment is not limited to this, and the transmitting unit 140 of each measuring device 10 may transmit placement position and orientation information, and the evaluation information generation unit 240 may identify the placement position and orientation of each measuring device 10 based on this information. 【0095】 For example, the measuring device 10 may have a GPS (Global Positioning System) sensor, and the transmitting unit 140 of the measuring device 10 may transmit position information acquired from the GPS sensor, thereby allowing the evaluation information generation unit 240 to identify the placement position and orientation of each measuring device 10. The evaluation information generation unit 240 may determine that the measuring device 10 located between two measuring devices 10 in the position information is facing the center, and that one of the two measuring devices 10 is facing left relative to the center, and the other is facing right. 【0096】 Furthermore, for example, the support devices 81, 84 and the member to be attached 89 may have a storage medium such as an IC tag or RF tag that stores information indicating the placement position and orientation at the position where the measuring device 10 is attached. In this case, the measuring device 10 may have a reading device such as an IC reader or RF reader, and the reading device will read the information stored in the IC tag or RF tag, etc., and the transmission unit 140 will transmit it to the evaluation device 20, so that the evaluation information generation unit 240 of the evaluation device 20 can identify the placement position and orientation of each measuring device 10. In this way as well, the evaluation information generation unit 240 can generate evaluation information including information indicating the direction of movement of the moving body based on the speed measured by the multiple measuring devices 10. 【0097】 (3) In the embodiment, an example was described in which the moving object is an object moved by the person being measured (such as the tip of the bat 3, the ball 4, or the club head 5 of a golf club). Here, when the ball 4 is the object being measured, for example, it becomes possible to output evaluation information including information such as the direction of movement of the ball 4 hit by the batter who is being measured. Alternatively, multiple measuring devices 10 may be used to simultaneously measure the movement of the tip of the bat 3 and the movement of the ball 4. In this case, the evaluation information generation unit 240 may generate evaluation information including information about the movement of the tip of the bat 3 and information about the movement of the ball 4, or it may generate comprehensive evaluation information regarding both the movement of the tip of the bat 3 and the movement of the ball 4. In this way, the movement of the tip of the bat 3 and the movement of the ball 4 can be evaluated simultaneously. 【0098】 Alternatively, part or all of the subject's body may be used as a moving object, and the speed of part or all of the subject's body may be measured using multiple measuring devices 10. In this example as well, the second evaluation display control unit 250 of the evaluation device 20 can output evaluation information regarding the movement of the moving object based on the speed information measured by the multiple measuring devices 10. The evaluation system 1 can, for example, generate evaluation information regarding the movement of a boxer's fist or a runner's running speed by measuring these speeds with multiple measuring devices 10.
