Description

  The present invention relates to a program, an information processing apparatus, a travel data evaluation system, and a measurement apparatus.

  There are moving bodies, such as a run bike and a bicycle, which are driven by the movement of the driver. In such a mobile, the speed and the like largely change depending on the driver's driving skill. There are also sports and competitions where the driver runs the moving body and competes in the ranking. For example, there may be cases where a beginner who is just starting to get on the moving body or a senior senior who suffers from skill improvement wants to improve their skills. is there.

  As one of the methods for skill-up, there is known a method in which a sensor or the like attached to a moving body detects traveling data, and an information processing apparatus analyzes the traveling data to digitize the current driving ability. For example, if it is possible to quantify how fast the driver actually travels on a moving body and how much acceleration can be given, etc., it is possible to objectively evaluate how much driving ability it currently has. , The driver can work on appropriate exercises to improve driving skills.

  A sensor is attached to the mobile as described above to obtain travel data. In order to detect correct traveling data, it is necessary for the driver or the like to attach the sensor to the moving object correctly (inclination or the like must be within a prescribed range). If the sensor is not attached in the correct direction, the information processing apparatus can not correctly determine the direction in which the moving object is traveling.

  As a method of determining whether or not the sensor is correctly attached, a method using the direction of gravity is known (see, for example, Patent Documents 1 and 2). Since the gravitational acceleration acts downward in the vertical direction, the orientation of the sensor such as the vertical direction can be determined depending on which direction the acceleration sensor detects the gravitational acceleration.

Japanese Patent Application Publication No. 2004-264202 JP, 2006-155180, A

  However, in the conventional method of determining whether or not the measuring device including the sensor is correctly attached, there is a problem that the posture of the moving body is not considered. This will be described with reference to FIG. FIG. 1 is an example of a diagram for explaining the relationship between the attitude of a moving object and the attitude of a measuring device.

  FIG. 1 (a) shows the measuring device correctly attached to the mobile. In FIG. 1, the upward arrow of the measuring device 10 indicates the upward direction of the measuring device 10, and the forward arrow indicates the forward direction of the measuring device 10. In FIG. 1A, the moving body 9 is upright, the upper direction of the measuring device 10 coincides with the upper direction of the moving body, and the forward direction of the measuring device 10 coincides with the forward direction of the moving body 9. Therefore, the measuring device 10 is correctly attached to the moving body 9. Since the measuring device 10 detects downward gravity acceleration, the information processing device that analyzes the data of the measuring device can judge that the measuring device 10 is correctly attached.

  On the other hand, in FIG. 1B, the measuring device 10 and the moving body 9 in which the information processing apparatus erroneously determines that the measuring device 10 is not correctly attached to the moving body 9 but are correctly attached to the moving body 9 Indicates In FIG. 1 (b), the measuring device 10 is attached with the movable body 9 placed upside down. The upward direction of the measuring device 10 is directed downward of the moving body 9, and the forward direction of the measuring device 10 is directed rearward of the moving body 9. Therefore, the measuring device 10 is not properly attached. However, since the measuring apparatus 10 detects downward gravity acceleration, the information processing apparatus erroneously determines that the measuring apparatus 10 is correctly attached.

  In particular, in the case of a mobile unit 9 which is often not equipped with a stand such as a run bike, since the mobile unit 9 can not maintain a standing state, it may be placed upside down in maintenance etc. May be high.

  In addition, such a problem is not limited to a moving body that moves with the movement of the driver as a power, and may also occur in a powered two-wheeled vehicle or four-wheeled vehicle.

  An object of the present invention is to provide a program capable of judging whether or not a measuring device is properly attached in view of the above-mentioned problems.

<Summary of operation>
FIG. 2: is an example of the figure explaining the method to specify the attachment direction of the measuring apparatus 10 by the travel data evaluation system of this embodiment. As shown in FIG. 2, the measuring device 10 is fixed to a part of the movable body 9 (for example, a seat stay, a chain stay, etc.). As a result, it is possible to detect the velocity, acceleration, attitude, and changes thereof (yaw angle, roll angle, pitching angle) of the moving body 9 and the like. The data detected by the measuring device 10 is referred to as travel data. The travel data is preferably transmitted to the information processing device 30 in real time. Although the information processing device 30 is held by the related person 7 (a relative, a friend, etc.) of the driver 8, the information processing device 30 may be held by the driver 8 or may be placed at any place. Good. The measuring device 10 of FIG. 2 is mounted upside down with respect to the movable body 9 for the sake of explanation.

The information processing device 30 specifies the mounting direction of the measuring device 10 using the rotation and acceleration of the wheels in the traveling data.
A. First, the information processing apparatus 30 specifies the mounting direction of the measuring apparatus 10 when the wheel is rotating. The mobile unit 9 is in a state in which it is estimated that it is moving (a state of being normally used), and the information processing apparatus 30 needs to instruct again to put the mobile unit 9 in a specific state (e.g., a riding state). Absent. In addition, it is not requested | required until the driver 8 actually rotates a mobile body, such as rotating a wheel.
B. When the wheel is rotating, the information processing device 30 monitors the acceleration. In the example of FIG. 2, since it is detected that the direction of gravity is upward with respect to the measuring device 10, the information processing device 30 determines that the measuring device 10 is upside down. The information processing device 30 outputs that the sensor is upside down.

  As described above, when the information processing apparatus 30 detects the rotation of the wheel, it estimates that the driver 8 is riding and moving, and detects the direction of gravity from the direction in which the acceleration acts at that time, and performs measurement. Identify the mounting direction of the device 10.

  Therefore, the driver 8 can grasp whether the orientation of the measuring device 10 is correct in the natural usage, the normal usage, or the general usage of the moving body 9.

  In addition, when the acquired gravity direction is different from the assumption (the gravity direction is downward with respect to the measuring device 10), the information processing device 30 mounts the measuring device 10 determined from the gravitational acceleration (upside down, upside down (left / right) Etc.). That is, since the actual direction (mounting method) of the measuring device 10 is output instead of simply "notifying an abnormality", the driver 8 or the person in charge 7 can determine by itself whether the mounting direction is correct.

  The driver 8 or the person in charge 7 may intentionally install the vehicle body sideways or upside down for maintenance or the like. In this case, even if the direction of gravity detected by the measuring device 10 is not downward, the mounting direction of the measuring device 10 may be correct, and if the information processing device 30 simply outputs an abnormality, the driver 8 or the person 7 There is a risk of mounting in the wrong direction by replacing the. In the present embodiment, when the information processing apparatus 30 outputs not the determination result (normal / abnormal) but the specified mounting direction, the driver 8 or the person in charge 7 can determine the presence or absence of the mounting error by itself. It will be possible to take appropriate action, such as reattaching the or reattaching.

<About terms>
The moving body means an object which moves by human power or power. The road surface may be moved by wheels or walking. The number of wheels may be one or more. For example, there is a walking robot as one that moves by walking. For example, there are run bikes (with or without pedals), bicycles, striders, unicycles, tricycles, etc., which move by wheels.

  In addition, the moving body includes a type in which the driver directly rides and which the pilot steers like a radio control. Also in this case, if the measuring device is attached, traveling data is similarly acquired. Further, in the present embodiment, a moving body powered by human motion is described as an example, but the moving body may be a vehicle (including a motorcycle) equipped with an engine.

  The related person 7 is mainly a driver's relative, a friend or the like, but may be a user of the information processing apparatus 30 in the present embodiment. In addition, the driver 8 may be called by a name suitable for a moving object, such as a person, a person, an operator, a pilot, a pilot, a user, or the like.

<Configuration example>
FIG. 3 is an example of a configuration diagram of the traveling data evaluation system 100. As shown in FIG. The traveling data evaluation system 100 includes a measuring device 10, an information processing device 30, and a server 50. The measuring device 10 is attachable to the moving body 9 and has one or more sensors for detecting traveling data suitable for evaluating the driving skill of the moving body 9 by the driver 8. As an example, such sensors include an acceleration sensor, a gyro sensor, and a rotation sensor. Although the measuring device 10 is attached to the chain stay 6 of the movable body 9 in FIG. 3, the mounting position of the measuring device 10 is not limited to the illustrated position. However, it is preferable that the rotation sensor be mounted near the spokes to detect disjunction (approaching or separating) of the magnets mounted on the spokes. In addition, since the information processing apparatus 30 can not correctly determine the traveling direction, the posture, and the like unless the measuring device 10 is mounted on the moving body 9 in the correct posture, it can be mounted vertically and mounted at a position that does not interfere with driving. preferable.

  The measuring device 10 and the magnet can be separately attached to and removed from the moving body 9, respectively, and can be attached to the moving body 9 or removed. Therefore, the measuring device 10 and the magnet are often distributed singly or as a set of assemblies. However, the measuring device 10 and the magnet 20 may flow together with the moving body 9 in a state of being attached to the moving body 9.

  The measuring device 10 and the information processing device 30 communicate at least wirelessly, and preferably also enable wired communication. Since it is preferable that the measuring device 10 and the information processing device 30 can communicate while the moving body 9 is traveling on the traveling course according to the mission, the communication system can communicate at a distance of several tens of meters (for example, 30 meters). connect. For example, Bluetooth (registered trademark) or Bluetooth Low Energy (registered trademark) can be mentioned. Besides, a communication method such as a wireless LAN or ZigBee (registered trademark) may be adopted. Alternatively, the measuring device 10 and the information processing device 30 may communicate via a relay server on a network connected by a mobile telephone network or the like.

  On the other hand, the measuring device 10 and the information processing device 30 may not be able to wirelessly communicate a certain distance. Also, no wireless communication may be possible. Since the capacity of the traveling data acquired by the measuring device 10 in one traveling is not so large, the traveling data during traveling of the measuring device 10 is stored. The traveling data stored during traveling is transmitted to the information processing device 30 by the measuring device 10 after traveling. For transmission, near-field wireless communication such as NFC (Near Filed Communication) may be employed other than Bluetooth and wireless LAN, or communication may be performed by wire. Alternatively, the traveling data may be acquired by mounting the removable memory card mounted on the measuring device 10 and reading the traveling data.

  It is also possible that the information processing device 30 doubles as the measuring device 10. In this case, the information processing device 30 includes the same sensor as the measuring device 10. Therefore, the measuring device 10 is not necessary.

  The information processing device 30 performs acquisition of traveling data, communication with the server 50, various screen displays (providing a user interface), and the like. In the information processing apparatus 30, an application (hereinafter referred to as a skill evaluation application) that performs processing related to travel data is operating. The skill evaluation application may be a browser or an application dedicated to the travel data evaluation system. The skill evaluation application may be downloaded from the server for program distribution to the information processing apparatus 30, or may be distributed in a state of being stored in a storage medium. Also, it may be distributed together with at least one of the measuring device 10 and the magnet 20.

  The information processing apparatus 30 may be one that operates a skill evaluation application, but specifically, it is advantageous for portability of a smartphone, a tablet terminal, a laptop PC (Personal Computer), or a wearable PC such as a watch type or a sunglasses type. The thing is mentioned. However, it may be a stationary information processing apparatus 30 such as a desktop PC.

  The information processing device 30 and the server 50 communicate via the network N. The network N is, for example, the Internet, but may include a communication network of a line carrier (carrier) for connecting to the Internet, a network of a provider, and the like. The information processing device 30 and the server 50 may communicate by wire.

  The server 50 is an example of an information processing apparatus that performs processing related to evaluation of traveling data. The server 50 analyzes the traveling data transmitted from the information processing device 30, and transmits the analysis result to the information processing device 30. Also, the server 50 manages the mission being performed by each driver 8 and provides a reward when the mission is completed. In addition, the ranking is published by comparing the levels of a plurality of drivers 8.

  The skill evaluation application of the information processing device 30 may execute a process related to evaluation of traveling data performed by the server 50. In this case, the server 50 is unnecessary, and communication with the server 50 is also unnecessary. However, the load on the skill evaluation application may increase, or the skill evaluation application may need to be updated instead of the server 50 update. Thus, the information processing apparatus 30 may execute one or more or all of the functions of the server 50, and the information processing apparatus 30 and the server 50 can be regarded as one information processing system or one apparatus.

  The server 50 is preferably compatible with cloud computing. Cloud computing refers to a usage form in which resources on a network are used without being aware of specific hardware resources. Specific forms of cloud computing include, for example, Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), but any form may be used in this embodiment. Good. In addition, a predetermined device may operate as the server 50 without supporting cloud computing.

<Hardware example>
<< Hardware Example of Measurement Device >>
FIG. 4 is a diagram showing an example of the hardware configuration of the measuring apparatus 10. As shown in FIG. The measuring device 10 includes, for example, an acceleration sensor 11, a gyro sensor 12, a rotation sensor 13, a memory 14, a control unit 15, a near field communication unit 16, a battery 17, and a power switch 18. Note that FIG. 4 only shows the main elements of the measuring apparatus 10, and may have elements other than those illustrated.

  The acceleration sensor 11 is a three-axis acceleration sensor 11 that detects acceleration in the vertical direction, front-rear direction, and left-right direction of the measuring device 10. Therefore, vertical and horizontal movement of the movable body 9 to which the measuring device 10 is attached can be detected. By being able to detect accelerations in multiple directions in this way, various travel data can be acquired.

  The gyro sensor 12 is an angular velocity sensor that detects at least an angular velocity of a yaw angle. The information processing device 30 can measure the yaw angle by integrating the angular velocity. In addition to this, it is more preferable to be able to detect the roll angle and the pitching angle of the moving body 9 to which the measuring device 10 is attached in order to obtain the change of the attitude of the moving body 9 in more detail.

  The rotation sensor 13 is a sensor that detects the rotation of the wheel of the moving body 9. First, the magnet 20 is fixed to one or more of the spokes 21 of the moving body 9. The magnet 20 is attached to the spoke 21 so as to pass through the detection range of the magnet 20 by the rotation sensor 13 when the measuring device 10 is attached to the moving body 9. One form of the rotation sensor 13 is a magnet switch. The magnet switch is a switch that is turned on by the approach of the magnet 20 and turned off by the separation (or vice versa). There is also a magnetic sensor as another form. The magnetic sensor detects the size and direction of the magnet 20 or the magnetism or geomagnetism generated by the current. In the case of a magnetic sensor, the manufacturer etc. can arbitrarily set the threshold of the magnetic force determined by the control unit 15 that the magnet 20 has been detected, to a certain extent, so that the wheel can be used even if the distance between the rotation sensor 13 and the magnet 20 Makes it easy to detect There are also magnetic sensors that can detect the direction of rotation. The rotation sensor 13 generates data “1” at the timing when the magnet 20 is detected, and generates data “0” at other timings. The information processing device 30 (or the server 50) can calculate the rotational speed according to how many “1s” exist per unit time, and calculate the travel distance by multiplying the rotational speed by the length of the circumference of the wheel.

  The control unit 15 controls the entire operation of the measuring device 10. The control unit 15 has, for example, a CPU, a RAM, and a ROM for storing a program. The control unit 15 controls the operation mode (a simple measurement mode, a high accuracy mode, a fall determination mode, an energy saving mode, etc.) of the measuring device 10, and the sensor of the measuring device 10 shown in FIG. Make the driving data detected. In addition, when the traveling data is detected, the short distance communication unit 16 transmits the traveling data to the information processing device 30. The control unit 15 also controls the battery 17 to supply power to the components determined in the operation mode.

An example of a sensor operating in each operation mode is as follows.
Simple measurement mode: Only the rotation sensor 13 operates. This operation mode is started by pressing a speed monitor button 315 described later. The speed and travel distance are monitored in real time by the data of the rotation sensor 13.
・ High precision mode: All sensors operate. This operation mode is started by pressing a start button 334 described later.
Overturn determination mode: This is an operation mode in which only the acceleration sensor 11 operates and determines the presence or absence of overturn. For example, when operating in the simple measurement mode or the high accuracy mode but the rotation sensor 13 does not detect rotation for a long time, the information processing device 30 transmits a control signal to shift to the overturn determination mode. In the fall determination mode, the presence or absence of a fall is determined by the acceleration detected by the acceleration sensor 11.
Energy saving mode: This is an operation mode in which only communication with the information processing device 30 is performed. The energy saving mode may have multiple levels of status. For example, the power may be automatically turned off.

  The memory 14 is storage means for storing traveling data detected by the acceleration sensor 11, the gyro sensor 12, and the rotation sensor 13. For example, a nonvolatile flash memory may be a volatile memory that holds information only while power is supplied. The memory 14 may be removable. When the short distance communication unit 16 has established communication with the information processing device 30, the control unit 15 causes the information processing device 30 to transmit the traveling data stored in the memory 14. The transmitted travel data is deleted or overwritten, and is not transmitted again. The measuring device 10 can transmit in real time, transmit each time one or more runs, or transmit to the information processing device 30 according to the operation of the driver 8 or the person in charge 7. The memory 14 is stored once or more (preferably a plurality of times) so that the traveling data can be stored even if the distance between the measuring device 10 and the information processing device 30 increases to the extent that communication is difficult or the radio wave becomes weak. It is preferable to have a capacity to hold travel data of the travel of the vehicle.

  The short distance communication unit 16 is a communication device that communicates with the information processing device 30 wirelessly. As described above, there are Bluetooth etc. as a communication method. When the measuring device 10 communicates with the information processing device 30 for the first time, the skill evaluation application requests the driver 8 or the person in charge 7 to input an ID for pairing. The ID is identification information unique to the measuring device 10 and is packaged with the measuring device 10. Thereby, the measuring device 10 and the information processing device 30 are paired to establish communication. When communication is established, the near field communication unit 16 monitors the life and death of the other party and detects disconnection of the communication if there is no response from the other party.

  The battery 17 is a power supply for operating the measuring device 10. It may be a primary battery or a secondary battery. When the power switch 18 is turned on, power is supplied from the battery 17 to the control unit 15, the control unit 15 is reset, and the control unit 15 reads a program to start the measuring device 10. The activated control unit 15 causes the short distance communication unit 16 to communicate with the information processing device 30. As described above, communication can be automatically started with the information processing device 30 by the activation of the measurement device 10 or the operation of the driver 8 or the person in charge 7.

<< Hardware Example of Information Processing Device >>
FIG. 5 is an example of a hardware configuration diagram of the information processing apparatus 30. The information processing device 30 includes an input device 31, a display device 32, a short distance communication unit 33, a long distance communication unit 34, a ROM 35, a RAM 36, an auxiliary storage device 37, and a CPU 39 as hardware components. Note that FIG. 5 only shows the main elements of the information processing apparatus 30, and may have elements other than those illustrated.

  The CPU 39 executes various programs and performs arithmetic processing. The ROM 35 stores programs necessary for activating the information processing device 30. The RAM 36 is a work area for temporarily storing the result of processing by the CPU 39 and storing programs and data.

  The auxiliary storage device 37 is non-volatile storage means for storing various data and programs 37p. The program 37p includes an OS, communication software, and a skill evaluation application. The input device 31 is, for example, a touch panel and a hard key. The display device 32 is a display device such as liquid crystal or organic EL.

  The short distance communication unit 33 of the information processing device 30 has the same function as the short distance communication unit 16 of the measuring device 10. The long-distance communication unit 34 connects to the base station by a communication method such as 3G, 4G, LTE, etc., and connects to the network N via the base station to perform communication with the server 50. The long distance communication unit 34 may communicate by a communication method such as a wireless LAN or WiMax.

  In addition to this, the information processing apparatus 30 may have a microphone, a camera, an external I / F, an acceleration sensor, an azimuth sensor (magnetic sensor), a GPS (Global Positioning System) receiving apparatus, and the like.

  The program 37p (skill evaluation application) stored in the auxiliary storage device 37 of the information processing device 30 may be distributed by downloading from a server for program distribution, or is stored in a storage medium (not shown). May be distributed at

  The hardware configuration of the server 50 is the same as that of a general server apparatus (general information processing apparatus), and even if there is a difference, there is no problem in the description of the present embodiment.

<About function>
The functions of the measurement apparatus 10, the information processing apparatus 30, and the server 50 will be described with reference to FIG. FIG. 6 is an example of a functional block diagram showing the functions of the measuring device 10, the information processing device 30, and the server 50 in the traveling data evaluation system 100 in block form.

<< Measurement device >>
The measuring device 10 includes a traveling data detection unit 61, a control execution unit 62, a traveling data transmission unit 63, and a control signal reception unit 64. Each of these functions of the measurement apparatus 10 is a function or means implemented by the control unit 15 of the measurement apparatus 10 executing a program and controlling each component of the measurement apparatus 10.

  The travel data detection unit 61 is a function realized by the operations of the acceleration sensor 11, the gyro sensor 12, and the rotation sensor 13, and detects travel data of acceleration, angular velocity, and rotational speed. The travel data transmission unit 63 transmits the travel data to the information processing device 30. The timing of transmission is various as described above, but the start and end (one run data) of one run can be known by a control signal described later.

  The control signal receiving unit 64 receives a control signal from the information processing device 30. The control signals are, for example, measurement start, stop, start / stop of designated sensor, and measurement end. There may be various control signals in addition to this. The control execution unit 62 controls the measuring device 10 based on the control signal. The operation mode is determined according to the control signal, and acquisition and acquisition of traveling data are started and ended. For example, the operation mode of the measuring apparatus 10 is shifted to the high accuracy mode by the control signal of measurement start, and the traveling data detection unit 61 starts the detection of traveling data. In response to the control signal of measurement completion, the travel data detection unit 61 stops the detection of the travel data, and shifts the operation mode of the measuring device 10 to the energy saving mode.

<< Information processing device >>
The information processing apparatus 30 includes a travel data acquisition unit 71, an attachment direction determination unit 72, a screen display unit 73, a control signal transmission unit 74, a login request unit 75, an analysis request unit 76, an analysis result acquisition unit 77, and an operation reception unit 78. Have. These functions of the information processing device 30 are realized by the CPU 39 of the information processing device 30 executing the program 37p developed from the auxiliary storage device 37 to the RAM 36 to control the components of the information processing device 30. Function or means.

  The travel data acquisition unit 71 acquires travel data from the measuring device 10. Acquisition of driving data is performed by the skill evaluation application being measured by the operation of the driver 8 or the person in charge 7. When travel data is transmitted in real time, the fact that the travel data acquisition unit 71 is acquiring travel data means that the driver 8 is traveling (the communication between the person 7 and the driver 8 is successful? Situations such as the driver 8 not traveling may occur). If the radio wave intensity decreases while acquiring the traveling data, the traveling data acquisition unit 71 acquires the traveling data when the communication is established again. When the measuring device 10 holds traveling data instead of real time, for example, acquisition of the traveling data is started by turning on the power switch 18 of the measuring device 10 and is ended by turning off. Then, communication is established, and when the skill evaluation application is under measurement by the operation of the driver 8 or the person in charge 7, travel data is acquired. The measuring apparatus 10 may have a switch for data transfer.

  The travel data acquisition unit 71 causes the travel data storage unit 79 to store one travel data. The traveling data holding unit 79 holds one or more traveling data in time series. That is, from the start of measurement to the end of measurement, each data of rotational speed, acceleration, and angular velocity is held in association with time (which may be absolute time or relative time).

  The mounting direction determination unit 72 determines the direction of the measuring device 10 attached to the moving body 9 using the rotational speed and the acceleration among the traveling data. The mounting direction determination unit 72 includes a movement estimation unit 72a and a gravity direction identification unit 72b. The movement estimation unit 72a determines whether it can be estimated that the moving body 9 is moving regardless of whether it is actually moving. The gravity direction identification unit 72b identifies the mounting direction in which the measuring device 10 is attached based on the acceleration. The travel data acquisition unit 71 sends at least the rotational speed and the acceleration of the travel data to the mounting direction determination unit 72. The specification of the mounting direction does not have to be always performed. Normally, traveling data from the detection of wheel rotation to a predetermined number of rotations, traveling data from the first 1 to 10 seconds when acquisition of traveling data is started, or the number of rotations of the wheel is detected It can be judged by the traveling data of the second.

  The analysis request unit 76 transmits an analysis request including the traveling data held in the traveling data holding unit 79 to the server 50. The analysis request unit 76 collectively transmits traveling data (from the start of traveling to the end of traveling) for one traveling, to the server 50. A traveling course, which will be described later, is also transmitted. The analysis request unit 76 can also transmit traveling data for a plurality of travelings in one transmission.

  The analysis result acquisition unit 77 acquires an analysis result from the server 50. In the present embodiment, the details of the analysis procedure will be described as necessary. The analysis result is, for example, the level of driving skill in each category, the mission, the progress of the mission, and the completion of the mission. Further, the analysis result acquisition unit 77 can acquire various other information. Table 1 shows an example of categories, levels and missions.

  The screen display unit 73 displays various screens on the display device 32 of the information processing device 30. Examples of these screens are shown in FIG. 7 and FIG. In addition, the screen display unit 73 changes the screen in accordance with the operation received by the operation receiving unit 78. The screen display unit 73 not only displays the screen on the display device 32, but also outputs voice according to the screen or separately from the screen.

  The operation receiving unit 78 receives various operations of the driver 8 or the related person 7 on the information processing device 30. The operation content accepted by the operation accepting unit 78 is sent to the screen display unit 73, the control signal transmission unit 74, the login request unit 75, and the like.

  The control signal transmission unit 74 transmits, for example, a control signal corresponding to the content of the operation to the measuring device 10. As described above, the control signal is, for example, measurement start, stop, start / stop of designated sensor, measurement end, and the like. The login request unit 75 transmits a login request to the server 50 together with the identification information of the driver 8 or the related person 7 and the password (account information). Login refers to an authentication operation of accessing data of an individual using account information registered in advance when using a service provided by the server 50. Sometimes called logon. The identification information may be an e-mail address or an ID of a skill evaluation application. The driver 8 or the person in charge 7 may input the identification information and the password to the information processing apparatus 30, or the information processing apparatus 30 may store the identification information and the password.

<< Server >>
The server 50 includes an authentication unit 81, an analysis unit 82, an analysis result transmission unit 83, and an analysis request acquisition unit 84. Each of these functions of the server 50 is a function or means implemented by the CPU of the server 50 executing a program expanded from the auxiliary storage device to the RAM and controlling the respective components of the server 50. In FIG. 6, only the main functions of the functions of the server 50 are shown, and the functions that do not interfere with the description of the present embodiment are omitted.

  Also, the server 50 has a user information DB 85. These are storage means built in an HDD (Hard Disk Drive), flash memory, RAM, etc. that can be used by the server 50.

表１はユーザ情報ＤＢ８５が記憶するユーザ情報テーブルの一例である。ユーザ情報テーブルは、各運転者８に関する情報を有している。ニックネームは運転者８の愛称である。本名であってもよい。識別情報とパスワードは運転者８又は関係者７のアカウントである。最新レベルは、運転者８の最新の（現在の）カテゴリごとのレベルである。カテゴリは運転能力が区分されたものである。現在のミッションは、運転者８が現在、遂行しているミッションの内容である。ミッションの進捗状況は、現在のミッションがどのくらい進捗したかを示す。現在のミッションは複数あってもよく、その場合、ミッションの進捗状況はミッションごとに管理される。

Table 1 is an example of the user information table stored in the user information DB 85. The user information table has information on each driver 8. The nickname is a nickname of the driver 8. It may be a real name. The identification information and the password are accounts of the driver 8 or the person in charge 7. The latest level is a level for each latest (current) category of the driver 8. The category is classified into driving ability. The current mission is the content of the mission currently performed by the driver 8. The progress of the mission shows how much the current mission has progressed. There may be multiple current missions, in which case the progress of the mission is managed on a mission-by-mission basis.

  Referring back to FIG. The authentication unit 81 establishes the authentication depending on whether the same identification information and password as the identification information and password of the driver 8 (or the related person 7) held in advance in the user information DB 85 are included in the login request. Determine if it is or not. The driver 8 or the person concerned 7 can be identified by the certification being established.

  The analysis request acquisition unit 84 acquires an analysis request including travel data for at least one time from the information processing device 30, and sends the analysis request to the analysis unit 82. At this time, the traveling course described in FIG. 7 is also transmitted.

  The analysis unit 82 analyzes the traveling data to determine the level of the driver 8 for each category of propulsion, pitch, stride, speed, start, and corners shown in Table 1. Also, the analysis unit 82 determines the mission in accordance with the determined level. A mission is something that should be done to improve the driving skills of a mobile. You may call it a task or practice method. Therefore, the mission can be determined by the number of categories in one run. In this manner, a plurality of missions may be determined, and the server 50 may provide the driver 8 sequentially. In this case, the driver 8 or the related person 7 selects and executes a mission. Alternatively, the mission may be determined according to the lowest level category. The analysis unit 82 registers the mission determined as the level for each category in the user information DB 85. The analysis unit 82 manages the progress of the mission based on the traveling data, and updates the progress of the mission of the user information table.

  The analysis result such as the level and the mission is sent to the analysis result transmission unit 83, and the analysis result transmission unit 83 transmits the analysis result to the information processing apparatus 30.

The selected course is sent to the server 50 together with the travel data and used to manage the progress of the mission. Since the server 50 analyzes the traveling data based on the traveling course, it becomes easy to analyze the traveling data even if there is instability or the like. Therefore, it is preferable that the travel course corresponding to the mission is displayed on the course selection button 322 (even when displayed along with the name of a compatible mission).

<Operation procedure>
FIG. 9 is an example of a sequence diagram showing a procedure in which the measuring device 10 transmits traveling data to the information processing device 30. The measuring device 10 is attached to the moving body 9, and the skill evaluation application is installed in the information processing device 30.

  S1: The driver 8 or the related person 7 operates the information processing device 30 to activate the skill evaluation application.

  S2: Assuming that the user registration has already been completed, the driver 8 or the related person 7 presses the login button 302 on the initial screen 301, and the login request unit 75 transmits a login request (identification information and password) to the server 50 Do. In the present embodiment, it is assumed that login is possible.

  S3: Also, the driver 8 or the person in charge 7 presses the power switch 18 of the measuring device 10 to activate the measuring device 10.

  S4: The short distance communication unit 16 of the activated measuring device 10 automatically establishes communication with the information processing device 30 which has been paired.

  S5: The mounting direction determination unit 72 of the information processing device 30 detects the activation of the measuring device 10 when the communication is established. There is a possibility that the measurement apparatus 10 is attached immediately after the start-up, and if the attachment direction can be specified at the start-up, the driver 8 or the person 7 may easily cope with the attachment direction of the measurement apparatus 10 by mistake. Therefore, the mounting direction determination unit 72 specifies the mounting direction of the measuring device 10 at the timing when communication is established. Details will be described with reference to FIG. In the description of FIG. 9, it is assumed that the mounting direction is correct.

  S6: The operation reception unit 78 of the information processing device 30 receives the operation of the driver 8 or the related person 7, and the screen display unit 73 causes various screens to be displayed, and pressing of the start button 334 (measurement start) on the course confirmation screen 331 Accept

  S7: Thereby, the control signal transmission unit 74 of the information processing device 30 transmits a control signal (measurement start).

  S8: The control signal reception unit 64 of the measurement apparatus 10 receives the control signal (measurement start), and for measurement, the control execution unit 62 switches the operation mode to the high accuracy mode if necessary. If necessary, if the measuring apparatus 10 immediately after start-up is in the high accuracy mode, it is a case where it shifts to the energy saving mode by the reception of the control signal. In addition, if the measurement device 10 immediately after startup is in the energy saving mode, it is necessary to switch the operation mode.

  S9: The control execution unit 62 of the measuring device 10 causes the traveling data detection unit 61 to start detection of the traveling data. The travel data detection unit 61 starts detection of travel data.

  S10: The mounting direction determination unit 72 of the information processing device 30 specifies the mounting direction of the measuring device 10 until the wheels rotate a predetermined number of times, with the start of measurement of the traveling data. This makes it easy to suppress the driver 8 from traveling despite the mounting direction of the measuring device 10 being incorrect. In addition, when the operation mode for specifying the mounting direction of the measuring device 10 is provided, the measuring device 10 transmits the traveling data separately from the traveling data for level determination and mission determination, and the power consumption of the measuring device 10 is consumed. . In the present embodiment, when the information processing device 30 analyzes travel data, the mounting direction is specified, so it is possible to make it difficult to waste power consumption.

  S11: The traveling data transmission unit 63 of the measuring device 10 appropriately transmits the traveling data detected by the traveling data detection unit 61 to the information processing device 30. When the communication is interrupted, it may be transmitted when the communication is resumed.

  S12: The traveling data acquisition unit 71 of the information processing device 30 acquires traveling data and holds (stores) the traveling data in the traveling data holding unit 79.

  S13: If the driver 8 or the person in charge 7 determines that the driver 8 has finished traveling on the traveling course, the driver 8 or the person in charge 7 presses the end button 343 on the during measurement screen 341. The operation accepting unit 78 accepts this operation.

  S14: Thereby, the control signal transmission unit 74 of the information processing device 30 transmits a control signal (measurement completion).

  S15: The control signal reception unit 64 of the measurement apparatus 10 receives the control signal (measurement completion), the control execution unit 62 causes the traveling data detection unit 61 to stop detection of the traveling data, and switches the operation mode to the energy saving mode. It is not necessary to switch to the energy saving mode.

  In FIG. 9, the mounting direction of the measuring device 10 is specified at the start of measurement, but when the traveling data (data of the rotary switch) is transmitted by pressing the speed monitor button 315, the mounting direction of the measuring device 10 The identification of may be performed.

  FIG. 10 is an example of a sequence diagram showing a procedure in which the information processing apparatus 30 transmits an analysis request to the server 50 and acquires an analysis result. The process of FIG. 10 is performed following FIG.

  S21: The driver 8 or the person in charge 7 determines whether or not to analyze, considering whether it is appropriate to determine the level from the situation of traveling and the like. This embodiment will be described as an analysis. The driver 8 or the person in charge 7 presses the yes button 353 on the analysis confirmation screen 351. The operation accepting unit 78 accepts this operation.

  S22: The analysis request unit 76 of the information processing apparatus 30 transmits an analysis request including the traveling data of the traveling data storage unit 79 and the traveling course to the server 50.

  S23: The analysis request acquisition unit 84 of the server 50 acquires the analysis request and the traveling course, and the server 50 starts the analysis. The analysis determines the level and mission of each category of driving skills. The details of the determination method will be omitted.

  S24: The analysis result transmission unit 83 of the server 50 transmits the analysis result to the information processing apparatus 30.

  S25: The analysis result acquisition unit 77 of the information processing device 30 acquires the analysis result, and the screen display unit 73 displays the analysis result screen 371 on the display device 32. That is, the level and mission of each category of driving skill are displayed.

<Specific processing for mounting direction>
FIG. 11 is an example of a flowchart illustrating a procedure in which the information processing apparatus identifies the mounting direction. The process of FIG. 11 is executed when an event such as a transition of the operation mode of the measurement apparatus 10 or an operation of the driver 8 or the person 7 occurs when the skill evaluation application is activated.

  First, the mounting direction determination unit 72 determines whether it is time to specify the mounting direction (S101). The timing at which the mounting direction is specified is when the measuring device 10 is activated (at the start of communication) or when the operation mode for acquiring travel data is started. The operation mode for acquiring travel data is a simple measurement mode, a high accuracy mode, or a fall determination mode. Therefore, even when there is an opportunity to switch to these operation modes, the information processing device 30 does not immediately switch the operation mode of the measuring device 10. In addition, since there is a possibility that the wheel is not rotating in the overturn determination mode, the mounting direction may not be specified in the overturn determination mode. If it is not time to specify the mounting direction (No in S101), the process of FIG. 11 ends.

  If it is time to specify the mounting direction (Yes in S101), the mounting direction determination unit 72 transmits a control signal for activating the rotation sensor 13 and the acceleration sensor 11 to the measuring device 10 via the control signal transmission unit 74 (S102) ). That is, the rotation sensor and the acceleration sensor are activated prior to the operation mode of the transition destination. As a result, the mounting direction determination unit 72 can acquire data on the rotation of the wheel and the acceleration from the measuring device 10.

  Next, the movement estimation unit 72a determines whether the rotation sensor has detected the rotation of the wheel (S103). When the rotation sensor 13 detects passage of the magnet, it detects the rotation of the wheel and transmits it to the information processing apparatus 30, so that the movement estimation unit 72a indicates that the rotation has been detected each time (the data “1” above) get.

  When the rotation of the wheel is not detected (No in S103), the movement estimation unit 72a determines whether a predetermined time has elapsed from the determination in step S101 (S104). This determination is made to end the specification of the mounting direction when the rotation of the wheel is not detected. The battery consumption can be suppressed by determining the mounting direction of the measuring device 10 only while the predetermined time has elapsed.

  When the predetermined time has elapsed (Yes in S104), the process proceeds to step S110, and shifts to the operation mode that has triggered the specification of the mounting direction. Until the predetermined time elapses, the determination in step S103 is performed.

  When the rotation of the wheel is detected (Yes in S103), the movement estimation unit 72a further acquires data on the rotation of the wheel, and the gravity direction identification unit 72b monitors the acceleration (S105). The gravity direction identification unit 72b acquires and accumulates the acceleration until it is determined that the wheel has been rotated by at least the threshold in step S106.

  Next, the movement estimation unit 72a determines whether or not the wheels have rotated more than a threshold (S106). This determination is made to end the specification of the mounting direction when the rotation of the wheel is detected. As described above, the mounting direction can be specified only when the wheel rotates a fixed number of times after the timing to specify the mounting direction. The threshold value may be the number of rotations at which the moving body 9 can be determined to be used, and the number of rotations at which the number of accelerations necessary for specifying the mounting direction can be obtained. is there. It is preferable that the threshold be small so that the measuring device 10 can start detecting the traveling data for determining the level and the mission as soon as possible. If the threshold value is one rotation, it may be determined that the wheel has rotated more than the threshold value in step S106 due to the rotation detected in step S103. In this case, the acceleration acquired along with the data of the rotation sensor and the subsequent acceleration are used in step S103.

  If the wheel is not rotating above the threshold (No in S106), the process returns to step S105, and if the wheel rotates above the threshold (Yes in S106), the process proceeds to step S107.

  When the wheels rotate by the threshold or more, the gravity direction identification unit 72b determines whether the gravity acceleration is downward with respect to the measuring device 10 based on the acceleration (S107). Since the mounting direction of the measuring device 10 is determined only until the wheels rotate above the threshold value, the time for which the rotation sensor and the acceleration sensor consume power is shortened, and battery consumption can be suppressed.

  If the gravitational acceleration is downward with respect to the measuring device 10 (Yes in S107), the mounting direction of the moving body 9 is normal, so the gravity direction identification unit 72b determines that it is normal, and ends the processing. In this case, the control signal transmission unit transmits a control signal to the measuring device 10 to shift to a predetermined operation mode (S110). The predetermined operation mode is an operation mode that provides the timing for specifying the mounting direction in step S101.

  If the gravitational acceleration is not downward with respect to the measuring device 10 (No in S107), there is a possibility that the mounting direction of the movable body 9 is abnormal, so the gravity direction identifying unit 72b is an acceleration in the vertical direction, the lateral direction, or the longitudinal direction. It is specified where on the top, bottom, left, right, front, and back (or their middle) the measuring apparatus 10 faces (S108). Then, the screen display unit outputs the mounting direction of the measuring device 10 (S109).

  Thereafter, the control signal transmission unit 74 transmits a control signal to the measuring device 10 to shift to a predetermined operation mode (S110). If the mounting direction is normal, the driver 8 starts traveling as it is, or if there is a possibility that the mounting direction is not normal, the driver 8 may actually have the normal mounting direction. This is to start traveling and allow the measuring device 10 to start detection of traveling data.

  In the process of FIG. 11, the mounting direction is specified by the time the wheels rotate by the threshold value or more, but the mounting direction may be specified before the predetermined time (one second to several seconds) elapses from the determination of step S101. Good.

  In addition, when an acceleration that can specify the direction of gravity is detected without waiting for the rotation of the wheel that is equal to or greater than the threshold or the elapse of a predetermined time, the process may proceed to the process of step S107.

<Example of mounting direction output by information processing device>
FIG. 12 is an example of a diagram for explaining the vertical direction, the horizontal direction, and the front-rear direction of the measuring device 10. First, FIG. 12A shows the correspondence between the direction of the X axis Y axis Z axis and the direction of the measuring apparatus 10. As shown in FIG. 12A, an orthogonal coordinate system is defined in the measuring device 10, the + Y direction is the forward direction of the measuring device 10, the -Y direction is the backward direction of the measuring device 10, and the + Z direction is above the measuring device 10. The direction, -Z direction, is defined as the downward direction of the measuring device 10, the + X direction is the left direction of the measuring device 10, and the -X direction is the right direction of the measuring device 10. Note that this definition is only an example.

  Therefore, it is a normal state that the gravitational acceleration is detected in the -Z direction and the other accelerations in the X and Y directions become substantially zero.

  Further, as shown in FIG. 12B, the measuring apparatus 10 is mounted such that the + Y direction faces the front of the moving body 9 and the + Z direction faces the upper direction of the moving body 9 in a normal mounting direction. is there.

  Next, the mounting direction of the measuring device 10 to the movable body 9 and the mounting direction of the measuring device 10 output by the information processing device 30 will be described using FIG. FIG. 13 shows the mounting direction of the measuring device 10 which is output when the measuring device 10 is correctly mounted on the moving body 9. As shown in FIG. 13A, the mobile unit 9 is placed upside down. The measuring device 10 is attached to the moving body 9 such that the + Z direction is upward of the moving body and the + Y direction is forward of the moving body.

  The driver 8 or the person 7 manually rotates the wheel (by hand) to specify the mounting direction. Thus, the gravity direction identification unit 72b of the information processing device 30 can monitor the acceleration. Since the + Z direction of the measuring apparatus 10 is the direction of gravitational acceleration, the gravitational direction identifying unit 72b determines that the gravitational acceleration is the + Z direction (upward direction). Therefore, as illustrated in FIG. 13B, the screen display unit 73 of the information processing device 30 performs at least one of displaying a message “the measuring device is upside down” and outputting by voice (notification To do).

  However, since the driver 8 or the person in charge 7 turns the movable body 9 upside down for maintenance, it is natural that the measuring apparatus 10 is also upside down, and it can be judged that there is no abnormality.

  As described above, the driver 8 or the person in charge 7 can confirm the mounting direction if it can be estimated that the moving body is moving by the rotation of the wheel, regardless of whether the moving body 9 is actually moving.

  FIG. 14 shows the mounting direction of the measuring device 10 which is output when the measuring device 10 is erroneously mounted upside down on the movable body 9. As shown in FIG. 14A, the mobile unit 9 is placed upside down. The measuring device 10 is attached to the movable body 9 so that the + Z direction is downward of the movable body and the + Y direction is backward of the movable body.

  The driver 8 or the person in charge 7 manually rotates the wheels to specify the mounting direction. Thus, the gravity direction identification unit 72b of the information processing device 30 can monitor the acceleration. Since the −Z direction of the measuring apparatus 10 is the direction of gravitational acceleration, the gravitational acceleration is the −Z direction (downward direction), and the gravity direction identification unit 72b determines that the gravity direction is normal. Under the present circumstances, it is difficult to detect that the + Y direction is the backward direction of the moving body 9. Therefore, as shown in FIG. 14B, the screen display unit 73 of the information processing device 30 does not output anything.

  However, when the driver 8 runs the mobile unit 9 to start traveling, the state shown in FIG. Since the + Z direction of the measuring apparatus 10 is the direction of gravitational acceleration, the gravitational direction identifying unit 72b determines that the gravitational acceleration is the + Z direction (upward direction). For this reason, as shown in FIG. 14D, the screen display unit 73 of the information processing device 30 performs at least one of displaying a message “the measuring device is upside down” and outputting by voice.

  Since the driver 8 or the person in charge 7 has a normal orientation of the moving body 9, it can be determined that there is an abnormality in the mounting direction of the measuring device 10. As described above, even if the abnormality can not be detected in the state where the movable body 9 is placed upside down, when the driver 8 starts traveling, the information processing device 30 has a direction of gravitational acceleration different from assumed. In this case, the mounting direction of the measuring device 10 can be output.

  FIG. 15 shows the mounting direction of the measuring device 10, which is output when the measuring device 10 is correctly attached to the moving body 9, but the moving body 9 is turned over. As shown in FIG. 15A, the moving body 9 is placed with the left side down. The measuring apparatus 10 is attached to the movable body 9 so that the + X direction is the left direction of the movable body, and the + Z direction is the upward direction of the movable body.

  The driver 8 or the person in charge 7 manually rotates the wheels to specify the mounting direction. Thus, the gravity direction identification unit 72b of the information processing device 30 can monitor the acceleration. Since the + X direction is the direction of gravitational acceleration in the measuring apparatus 10, the gravity direction identification unit 72b determines that the gravitational acceleration is in the + X direction (left direction). For this reason, as shown in FIG. 15B, the screen display unit 73 of the information processing device 30 displays at least one of the message “Display the measuring device 10 is overturned (left)” or outputs by voice. Do.

  However, since the driver 8 or the person in charge 7 places the movable body 9 sideways for maintenance, it is natural that the measuring device 10 is also overturned, and it can be judged that there is no abnormality.

  When the + Z axis of the measuring device 10 is erroneously attached in FIG. 15A so that the + Z axis of the measuring device 10 is directed downward, the moving object 9 starts traveling, whereby the mounting direction of the measuring device 10 is obtained. Is output upside down.

When the movable body 9 is placed obliquely as shown in FIG. 16, the mounting direction of the measuring device 10 is specified by combining the outputs of two or more axes of the acceleration sensor. FIG. 16 is a view showing the moving body 9 and the measuring device which are inclined to the left side. When the measuring device 10 is correctly attached to the movable body 9, the gravitational acceleration is detected in the + X direction and the -Z direction. Assuming that the acceleration in the + X direction is Ax, and the acceleration (absolute value) in the -Z direction is Az, the inclination angle θ of the moving body 9 is calculated as follows.
θ = arctan (Ax / Az)
In this case, the information processing device 30 performs at least one of displaying a message that “the measuring device 10 is obliquely downward (left)” and outputting by voice. However, since the driver 8 or the person in charge 7 has placed the movable body 9 obliquely for maintenance, it can be judged that there is no abnormality.

<Summary>
As described above, the information processing apparatus 30 according to the present embodiment outputs the mounting direction in a state in which the mobile object is estimated to be moving, so natural usage, normal usage, or general usage In the above, the driver 8 can grasp the mounting direction of the moving body 9 whether or not the orientation of the measuring device 10 is correct. Even if the gravity direction is different from the assumed one, the driver 8 or the person 7 does not simply "notify the abnormality" but outputs the actual direction (mounting direction) of the measuring device 10, so the driver 8 or the person 7 determines whether the mounting direction is correct. I can judge myself.

<Other application examples>
As described above, the best mode for carrying out the present invention has been described using the examples, but the present invention is not limited to these examples at all, and various modifications can be made without departing from the scope of the present invention.

  Further, although it has been described that the speed is detected by the rotation sensor 13 in the present embodiment, the speed is converted to the speed by obtaining the optical flow from the change of the position information detected by the GPS receiver or the ground image data captured by the camera.
