It is given to the control unit 11. The housing of the electronic device 1 is a rectangular housing as a whole, and is associated with the three-axis directions of the acceleration sensor 18, for example, the direction of the short side of the housing is the X-axis direction, and the length of the housing is long.

Based on whether or not the moving body 2 has overcome the step on the road surface (passes a predetermined point), it is determined.

FIG. 3 is a block diagram showing the basic components of the mobile body management device 5.
The control unit 51, which forms the core of the mobile management device 5, operates by supplying electric power from the power supply unit 52, and performs the overall operation of the mobile management device 5 according to various programs stored in the storage unit 53. The control unit 51 is connected to the wide area communication unit 54, the operation unit 55, the display unit 56, the clock unit 57, and the like as peripheral devices thereof. The storage unit 53 has, for example, a configuration including a ROM, a flash memory, and the like, and stores a program, various applications, and the like for realizing the first embodiment according to the operation procedure shown in FIG. It has a configuration having a mobile management table MT, which will be described later. The wide area communication unit 54 is communicated and connected to the electronic device 1 on the mobile 2 side via the Internet 6, the public wireless communication network 7, and the smartphone 4 owned by the rider of the mobile 2.

Next, the operation concept of the road bike management system according to the first embodiment will be described with reference to the flowcharts shown in FIGS. 4 and 5. Here, each function described in these floats is stored in the form of a readable program code, and the operations according to the program code are sequentially executed. It is also possible to sequentially execute operations according to the above-mentioned program code transmitted via a transmission medium such as a network. This also applies to other embodiments described later, and in addition to the recording medium, it is also possible to execute an operation peculiar to the present embodiment by using a program / data externally supplied via a transmission medium.

FIG. 4 is a flowchart for explaining the operation of the electronic device 1 (characteristic operation of the present embodiment) that is started to be executed when the power is turned on. Participants (riders) of the competition perform an operation of turning on the power of the electronic device 1 at the start or immediately before the start.

First, the control unit 11 of the electronic device 1 starts the operation of activating the acceleration sensor 18 and acquiring the Z-axis acceleration as vibration data (step A1), and also starts the operation of acquiring the speed data from the speedometer 3. (Step A2), and further, the operation of associating the acquired vibration data with the velocity data and temporarily storing them in a ring buffer (not shown) is started (step A3). It should be noted that this ring buffer has, for example, a capacity capable of storing data for 5 seconds, has a ring buffer for vibration data and a ring buffer for speed data, and cyclically associates vibration data with speed data. It is configured to be temporarily stored. Then, the control unit 11 starts an operation of displaying the speed data acquired from the speedometer 3 on the touch display unit 16 numerically (step A4).

In this state, the control unit 11 checks whether or not the timing for determining whether or not the moving body 2 has passed a predetermined point (step) has reached the timing (step determination timing) (step A5). The step determination timing is preset time data (for example, timing at intervals of 5 seconds), and the control unit 11 determines that the time (5 seconds) indicated by the step determination timing has elapsed from the previous time (YES in step A5). A process of determining whether or not the moving body 2 has overcome the step is performed (step A6). That is, the vibration data detected by the acceleration sensor 18 is read from the ring buffer and analyzed, and the speed data detected by the speedometer 3 and the preset wheelbase are referred to in the vibration data. It is determined whether or not the moving body 2 has overcome the step based on whether or not a predetermined vibration waveform having a large impact is included in the data. Here, it will be described in detail with reference to FIGS. 6 and 7.

FIG. 6 is a diagram illustrating a vibration state due to an impact transmitted when a moving body 2 moving at a speed of 5 km / h gets over a step. FIG. 7 is a diagram illustrating a vibration state due to an impact transmitted when a moving body 2 moving at a speed of 25 km / h gets over a step in a case where the speed is different from the example of FIG. In the figure, the horizontal axis represents time, the vertical axis represents the Z-axis acceleration detected by the acceleration sensor 18, and the moving body 2 is added to the acceleration sensor 18 of the electronic device 1 according to the state of the road surface (unevenness or step) on which the moving body 2 travels. Since the impact changes, when the moving body 2 gets over a step of a predetermined height or more, the magnitude of its Z-axis acceleration changes significantly in the negative direction or the positive direction with reference to "0" by a predetermined threshold value or more. do.

In the figure, Pa shows a predetermined vibration waveform transmitted when the front wheel of the moving body 2 gets over the step, and Pb shows a predetermined vibration waveform transmitted when the rear wheel of the moving body 2 gets over the step. There is. The control unit 11 analyzes the displacement amount (vibration state) of the Z-axis acceleration, and the predetermined vibration waveforms Pa and Pb transmitted when the front wheels and the rear wheels get over the step are intermittently included in the displacement amount (vibration state) with a time lag. If so, it is determined that the moving body 2 has overcome the step. That is, for example, in order to eliminate the case where either the front wheel or the rear wheel of the moving body 2 rides on a pebble, it is determined whether or not the front wheel and the rear wheel get over the step on the road surface. In the example of FIG. 6, every time the front wheel and the rear wheel of the moving body 2 exceed the step, the vibration waveform at that time swings greatly in the negative direction, so that the same step (up step: rising step) is overcome. It turns out that. Here, if the speed of the moving body 2 is 5 km / h and the wheelbase is 1.15 m, the rear wheels will overcome the same step after a predetermined time of 895 ms after the front wheel exceeds the step.

Further, in the example of FIG. 7, each time the front wheel and the rear wheel of the moving body 2 get over the step, the vibration waveform at that time swings greatly in the positive direction, so that the same step (downward step; falling step) is formed. It can be seen that this is the case when the situation is overcome. Here, if the speed of the moving body 2 is 25 km / h and the wheelbase is 1.15 m, the rear wheels will overcome the same step 175 ms after the front wheel exceeds the step. In this way, the time difference between the front wheels and the rear wheels to get over the step can be obtained according to the speed of the moving body 2. Therefore, if this time difference corresponds to the speed of the moving body 2, the front wheels of the moving body 2 can be obtained. And it is determined that the rear wheel has overcome the step. In the example of FIG. 7, the time of the first step overcoming and the time of the second step overcoming are shown. When overcoming the second step, the vibration waveform at that time swings greatly in the negative direction each time the front and rear wheels of the moving body 2 cross the step, so the same step (up step: rising step) is overcome. It turns out that this is the case.

As a result of such determination, if the moving body 2 does not get over the step (NO in step A7), it returns to step A5 described above, but if it gets over the step (YES in step A7), it self from the start of the competition. In order to update the number of times the moving body 2 has crossed the step, "1" is added to the number of times the moving body 2 has crossed the step (step A8). The value of the number of times the step is overcome is "1" when the first step is overcome after the start of the competition. After that, a stepped signal (information indicating the timing of passing a predetermined point: indicating a vibration state) with a "self-moving body ID" that identifies the self-moving body 2 and a "step-overcoming number" from the start of the competition is added. Information) is generated and transmitted to the mobile management device 5 (step A9).

FIG. 5 is a flowchart for explaining the operation of the mobile body management device 5 (characteristic operation of the present embodiment). Note that FIG. 5 is a flowchart showing an outline of the operation of the feature portion of the present embodiment in the overall operation of the mobile body management device 5, and when the flow is exited from the flow of FIG. 5, the main flow of the overall operation is shown. Return to (not shown).
First, the control unit 51 of the mobile body management device 5 checks whether the instruction to start the competition has been received by key operation or the like (step B1), and if it does not receive the start instruction (NO in step B1), the control unit 51 exits this flow. , Return to the main flow of overall operation.

Upon receiving the instruction to start the competition (YES in step B1), it is checked whether a stepped signal (information indicating the timing of passing a predetermined point) has been received from any of the electronic devices 1 (step B2). When a stepped signal is received from any of the electronic devices 1 (YES in step B2), the "mobile ID" added to the stepped signal is acquired (step B3), and the "number of times the step is overcome" is acquired. (Step B4). Then, the mobile management table MT is accessed based on the acquired "moving body ID" and "number of times the step is overcome", and the order is selected from the determined rankings stored corresponding to the "number of times the step is overcome". Read the last rank (step B5).

FIG. 8 is a diagram for explaining the mobile body management table MT provided on the mobile body management device 5 side.
The mobile management table MT is a table for managing the mobile 2 participating in the competition and the electronic devices mounted on the mobile 2, and the "mobile ID" and "electronic device" for each mobile 2 are used. It has each item of "address", "rank of the first step", "rank of the second step", and so on. The "electronic device address" is a communication address for accessing the electronic device 1 mounted on the mobile body 2. The "rank of the first step" indicates the self-rank when the first step (first step) is overcome after the start of the competition, and the "rank of the second step" is the rank of the second step. It shows the self-ranking at the time. In the "rank of the first step" and "rank of the second step", the numerical values "1", "5", etc. indicate the rank from the beginning, and "-" indicates the rank. It indicates that it is undecided (not arrived).

When reading the determined order corresponding to the "number of steps over" from the mobile management table MT configured in this way, for example, if the received "number of steps over" is "1", the "first time" Read the determined rank stored in "Rank of steps". In the illustrated example, only the beginning is determined, and "1" is read as the end order from the determined order. If the number of times the step has been overcome is "2", the determined order stored in the "second step order" is read out. In the illustrated example, the fifth from the beginning has been determined, and "5" is read as the value (order) at the end of the determined order.

Then, a value obtained by adding "1" to the last value of the determined rank is determined as the rank of the mobile 2 indicated by the "mobile ID" (step B6). In the example of FIG. 8, if the number of times the step is overcome is "1", the value at the end of the determined rank is "1", so "2" is determined as the rank of the moving body. Further, if the number of times the step is overcome is "2", the value at the end of the determined rank is "5", so "6" is determined as the rank of the moving body. The newly determined rank is additionally stored in the mobile management table MT as the rank of the mobile 2 (step B7). That is, in the above-mentioned example, if the received "mobile ID" is "0002", "2" is additionally stored in the item of "rank of the first step" corresponding to this "0002", and "2" is additionally stored. "6" is additionally stored in the item of "rank of the second step".

Next, the "electronic device address" corresponding to the received "mobile ID" is read from the mobile management table MT, and the newly determined rank of the mobile is transmitted to the electronic device 1 (the process is performed). Step B8). After that, it is checked whether the instruction to end the competition has been received by key operation or the like (step B9), and if the instruction to end is not received (NO in step B9), the process returns to step B2 described above, but when the instruction to end is received (step B9). ), Exit this flow and return to the main flow of overall operation.

On the other hand, in the electronic device 1, if it is not the step determination timing for determining whether or not the moving body 2 has passed a predetermined point (step) (NO in step A5 of FIG. 4), the mobile body management device 5 self. It is checked whether the rank of the moving body of the above is received (step A10). Now, if the mobile body management device 5 does not receive its own ranking (NO in step A10), the process returns to step A5, but when the ranking is received (YES in step A10), the received ranking is displayed on the touch display unit 16. A process of displaying numerical values (step A11) is performed, and as another process using the order, for example, a calorie consumption calculation is performed (step A12). After that, the process returns to step A5, and the above operation is repeated. Since the air resistance of calories burned differs greatly depending on the order (rank) of the formation, in step A12, calorie calculation is performed according to the current rank.

As described above, in the first embodiment, the individually mounted electronic device (cyclocomputer) 1 of the mobile body (road bike) 2 detects the vibration transmitted to the device and is determined based on the vibration data. Since the order of the self-moving body 2 is acquired and a predetermined process is performed, the number of parts is smaller than in the conventional case, and a plurality of sensors are strictly mounted at a predetermined position, which is a mounting restriction. It is possible to properly manage the order of moving objects by a simple method called vibration detection.

The electronic device 1 analyzes the vibration state detected by the acceleration sensor 18, determines whether or not the moving body 2 has passed the predetermined point based on whether or not the predetermined vibration waveform is included, and determines whether or not the moving body 2 has passed the predetermined point. Since the timing of passing through is set as the ranking of the moving body of the self, it is possible to appropriately determine whether or not the vehicle has passed a predetermined point from the change in vibration, and the ranking is also appropriately determined.

The electronic device 1 analyzes the vibration state detected by the acceleration sensor 18, and if the moving body 2 includes a predetermined vibration waveform transmitted when the moving body 2 gets over a step on the road surface, the moving body 2 is used. Since it is determined that the vehicle has passed a predetermined point, a step on the road surface can be used as a predetermined point for determining the ranking.

In the electronic device 1, if a predetermined vibration waveform is intermittently included with a time lag, it is assumed that the front wheels and the rear wheels of the moving body (road bike) 2 have passed the predetermined point over the step on the road surface. Since the discrimination is performed, for example, it is possible to exclude the case where either the front wheel or the rear wheel rides on a pebble, and more appropriate discrimination becomes possible.

In the electronic device 1, when a predetermined vibration waveform is intermittently included with a time lag, and if the change of the intermittent vibration waveform is in the same direction, the front wheels and the rear wheels of the moving body 2 are on the road surface. Since it is determined that the vehicle has passed the predetermined point after overcoming the same step, it is possible to eliminate, for example, the case where either the front wheel or the rear wheel rides on a pebble, and more appropriate determination can be made. It will be possible.

In the electronic device 1, if the time difference of the predetermined vibration waveform transmitted when the front wheels and the rear wheels of the moving body 2 get over the step on the road surface corresponds to the speed of the moving body 2 measured by the speedometer 3. Since it is determined that the moving body 2 has passed a predetermined point, it is possible to make the determination without breaking the relationship between the front wheels and the rear wheels regardless of the speed change of the moving body 2.

When the electronic device 1 determines that it has passed a predetermined point (overcame a step on the road surface) in a state of being communication-connected to the mobile body management device 5 that manages a plurality of mobile bodies 2, the passage thereof Information indicating the timing (signal with a step) is transmitted to the mobile body management device 5, the rank of the own mobile body determined by the mobile body management device 5 is received based on the passing timing, and this rank is acquired. Since the predetermined processing is performed, it is possible to receive and process the ranking at the time of passing the predetermined point (overcoming the step on the road surface) in real time.

Since the electronic device 1 performs a process of acquiring and outputting the rank of its own mobile body, the rider of each mobile body 2 can know his / her own rank in real time. This allows you to know the difference from the current target ranking, and if you are at the top of the line, you can control the running pace, signal the rider behind you, and , Each following rider can keep the distance from the vehicle in front and send a signal to the rider behind.

In the first embodiment described above, when the electronic device 1 determines that it has passed a predetermined point (overcoming a step on the road surface), it manages the moving body with information (signal with a step) indicating the passing timing. The data was transmitted to the device 5, and the mobile body management device 5 determined the order in which the stepped signal was received to determine the order of the mobile body 2. However, the electronic device 1 detected the time when the stepped signal was detected (for example,). , 1/100 second unit time data), this time data is added to the stepped signal and transmitted to the mobile body management device 5, and the mobile body management device 5 adds the time added to the stepped signal. The ranking of each moving body 2 may be determined with reference to the data.

Further, in the first embodiment described above, when it is determined that the electronic device 1 has overcome the step on the road surface, the electronic device 1 transmits information indicating the passing timing (signal with a step) to the mobile body management device 5. Instead of transmitting the stepped signal indicating the vibration state, the vibration waveform signal detected by the acceleration sensor 18 or its characteristic information is sequentially transmitted to the mobile body management device 5 as information indicating the vibration state. You may. In this case, whether or not the moving body management device 5 has overcome the step on the road surface by sequentially analyzing the vibration waveform while receiving the information (vibration waveform signal or its characteristic information) indicating the vibration state from each electronic device 1. It may be determined whether or not, and the order when the moving body 2 is overcome is determined as the order of each moving body 2 and transmitted to the corresponding electronic device 1. If the mobile body management device 5 includes the process of analyzing the vibration waveform and determining whether or not the step has been overcome in this way, the burden on each electronic device 1 side can be significantly reduced. It becomes.

In the first embodiment described above, the electronic device 1 and the mobile management device 5 are communicated and connected via the Internet 6 and the public wireless communication network 7, but the configuration is such that the electronic device 1 and the mobile management device 5 are communicated and connected via a dedicated wireless LAN. May be.

(Second Embodiment)
Hereinafter, the second embodiment of the present invention will be described with reference to FIGS. 9 to 11.
In the first embodiment described above, the mobile body management is performed by communicating and connecting the electronic devices 1 individually mounted on the plurality of mobile bodies 2 and the mobile body management device 5 that manages the plurality of mobile bodies 2. Although the case where it is applied to the system is shown, in the second embodiment, among the electronic devices 1 individually mounted on the plurality of mobile bodies 2, the electronic device 1 that functions as the master device of the master-slave system and the slave device This is applied to a mobile management system in which a functioning electronic device 1 is connected by communication. As in the first embodiment, this second embodiment is also applied to a road bike management system that manages a plurality of moving bodies (road bikes) 2 participating in a competition (bicycle road race). Inside, the ranking indicating the order of the formation of the number of the multiple road bikes running from the beginning is managed in real time. Here, those having the same basic or nominal name in both embodiments are indicated with the same reference numerals, the description thereof will be omitted, and the feature portions of the second embodiment will be mainly described below. ..

FIG. 9 is a flowchart showing an outline of operation of the electronic device 1 that functions as a slave device.
First, the control unit 11 of the electronic device (slave device) 1 executes the same vibration / velocity start processing (step C1 in FIG. 9) as in steps A1 to A4 in FIG. 4 described above. That is, the operation of acquiring the vibration data and the velocity data is started, and the operation of temporarily storing the vibration data and the velocity data in the ring buffer is started. After that, it was checked whether it was the step determination timing (step C2), it was checked whether the master device requested the transmission of information to itself (step C8), and the order of the own moving body 2 was received from the master device. (Step C12).

Now, if it is the step discrimination timing (YES in step C2), the step discrimination process (step C3) similar to step A6 in FIG. 4 is performed, and if the step is not overcome (NO in step C4), the step C2 described above is performed. However, when the step is crossed (YES in step C4), "1" is added to the number of times the self-moving body 2 has crossed the step to update the value (step C5). Then, a stepped signal to which the "self-moving body ID" and the "step overcoming count" are added is generated (step C6), and the generated stepped signal is temporarily stored (step C7). Then, the process returns to step C2.

10 and 11 are flowcharts showing an outline of operation of the electronic device 1 functioning as a master device.
The control unit 11 of the electronic device (master device) 1 executes the same vibration / velocity start processing (step D1 in FIG. 10) as in steps A1 to A4 in FIG. 4 described above, and then checks whether the step determination timing is reached. (Step D2) If it is the step determination timing (YES in step D2), the same processing as in steps C3 to C7 of FIG. 9 is performed (step D3). That is, as a result of the step discrimination process, when the step is overcome, the number of times the step is overcome is updated, and then a stepped signal with "own mobile ID" and "number of times the step is overcome" is generated and temporarily stored. Perform the processing to be performed.

On the other hand, if it is not the step determination timing (NO in step D2), all the electronic devices 1 including the self (master device) are sequentially designated in sequence, and a process of requesting the designated device to transmit information is performed (step). D4). Now, if the designated device is self (YES in step D5), it is checked whether the signal with a step is temporarily stored (step D6), and if it is not temporarily stored, that is, if the step is not overcome (step). (NO in D6), the process returns to step D2 described above, but if the stepped signal is temporarily stored (YES in step D6), after performing the process of notifying the stepped signal to itself (step D7), This temporary storage stepped signal is erased (step D8).

Then, when the electronic device (master device) 1 receives the notification (stepped signal) addressed to itself, the electronic device (master device) 1 moves to step D10 of FIG. Get the number of times you got over it. Then, the mobile management table MT is accessed based on the acquired "moving body ID" and "number of times the step is overcome", and the order is selected from the determined rankings stored corresponding to the "number of times the step is overcome". The last rank is read (step D11). Then, when the rank of the own moving body 2 is determined by adding "1" to the end of the determined rank (step D12), the newly determined rank is associated with the moving body ID and the moving body. It is additionally stored in the management table MT (step D13). Then, again, it is checked whether the designated device is self (step D14), but since it is now self (master device) (YES in step D14), the determined self rank is numerically displayed on the touch display unit 16. (Step D15). After that, the process returns to step D2 of FIG.

On the other hand, when the electronic device (master device) 1 is not the designated device itself, that is, when the electronic device 2 (slave device) other than the master device is designated and the transmission of information is requested (step of FIG. 10). (NO in D5), the process proceeds to step D9 in FIG. 11 to check whether a stepped signal has been received from any of the slave devices.

When the electronic device (slave device) 1 is requested to transmit information to itself from the master device (YES in step C8 in FIG. 9), the electronic device (slave device) 1 checks whether the stepped signal is temporarily stored (step C9), and temporarily. If it is not memorized, that is, if the step is not overcome (NO in step C9), the process returns to step C2 described above, but if the step signal is temporarily stored (YES in step C9), this step signal is returned. Is read and transmitted to the master device (step C10). Then, after erasing the stepped signal of the temporary storage (step C11), the process returns to step C2 described above.

If the electronic device (master device) 1 does not receive the stepped signal (NO in step D9 in FIG. 11), the process returns to step D2 in FIG. 10, but the stepped signal from any electronic device (slave device) 1 (YES in step D9 in FIG. 11), the "moving body ID" and the "number of times the step has been overcome" added to the stepped signal are acquired (step D10). Then, the determined rank (last rank) corresponding to the number of times the step is overcome is read from the mobile management table MT (step D11), and the value obtained by adding "1" to the last value of the determined rank is specified. It is determined as the order of the device (mobile body) (step D12).

The newly determined rank is additionally stored in the mobile management table MT as the rank corresponding to the "mobile ID" (step D13). Then, it is checked whether the designated device is self (master device) (step D14), but since the designated device is not self (master device) now (NO in step D14), the determined order is assigned to the designated device (slave). After performing the process (step D16) of transmitting to the device), the process returns to step D2 of FIG. 10, and the above operation is repeated thereafter.

When the electronic device (slave device) 1 receives the rank of its own mobile body 2 from the master device (YES in step C12 of FIG. 9), the electronic device (slave device) 1 causes the touch display unit 16 to numerically display the received rank (step C13). After that, the process returns to step C2 described above, and the above operation is repeated thereafter.

As described above, in the second embodiment, the control unit 11 of the electronic device (master device) 1 has passed a predetermined point on the other electronic device (slave device) 1 side (overcoming a step on the road surface). When it is determined, the information indicating the passing timing is received, the order of the moving objects on the slave device side is determined based on the information indicating the passing timing, and the information is transmitted to the electronic device (slave device) 1. Therefore, in the case of the electronic device (master device) 1, the order of each moving body can be easily determined only by receiving the information indicating the passing timing from the other electronic device (slave device) 1 side. On the electronic device (slave device) 1 side, it is possible to receive and process the ranking at the time when the step on the road surface is overcome in real time.

The control unit 11 of the electronic device (master device) 1 is based on the information indicating the passing timing received from each of the electronic devices (slave device) 1, and the moving body on the electronic device (slave device) side is based on the difference in the timing. Since the ranking of is determined, the ranking can be determined accurately.

When the electronic device (slave device) 1 determines that it has passed a predetermined point, it transmits information indicating the passing timing to the electronic device (master device) 1 side, and is based on the information indicating the passing timing. Since the order of the moving body determined by the electronic device (master device) 1 side is received and the predetermined processing is performed, the predetermined point is set on the electronic device (slave device) 1 side. It is possible to receive and process the ranking at the time of passing (overcoming the step on the road surface) in real time.

In the second embodiment described above, the electronic device (master device) 1 requests the designated device to transmit information while periodically and sequentially designating any of the electronic devices 1 including itself, and responds to the request. Then, the information indicating the passing timing (signal with a step) is received from the designated device to determine the order of the moving body 2 on the designated device side, but the master device sequentially designates all the electronic devices 1. After requesting the transmission of information, information indicating the passage timing (stepped signal) may be sequentially received from each electronic device 1.

Further, although not particularly mentioned in the second embodiment, in the above-mentioned master / slave system, the master authority is sequentially transferred to another electronic device 1 without fixing the electronic device 1 functioning as the master device. You may. In this case, the transfer may be performed at regular intervals, but the transfer may be performed according to the user operation.

In the second embodiment described above, when the electronic device (slave device) 1 determines that it has passed a predetermined point (overcoming a step on the road surface), it electronically outputs information (signal with a step) indicating the passing timing. It is transmitted to the device (master device) 1, and the master device determines the order in which the stepped signal is received as the order of the moving body 2, but the slave device determines the time when the stepped signal is detected (the time when the stepped signal is detected. For example, time data in units of 1/100 second) is acquired, this time data is added to the stepped signal and transmitted to the master device, and the master device refers to the time data added to the stepped signal. , The order of each moving body 2 may be determined.

Further, also in the second embodiment described above, the electronic device (slave device) 1 vibrates the vibration waveform signal detected by the acceleration sensor 18 or its characteristic information instead of transmitting the stepped signal indicating the vibration state. The information indicating the state may be sequentially transmitted to the mobile body management device 5. In this case, the electronic device (master device) 1 determines whether or not the step on the road surface has been overcome by sequentially analyzing the vibration waveform while receiving the information indicating the vibration state from each slave device 1, and overcomes the vibration waveform. In this case, the order may be determined as the order of each moving body 2 and transmitted to the corresponding slave device 1. If the master device 1 analyzes the vibration waveform and determines whether or not the step has been overcome in this way, the burden on each slave device 1 can be significantly reduced. ..

Further, although the above-described second embodiment is applied to the master / slave type mobile management system, the method is not limited to the master / slave type and may be the following method.
That is, each electronic device 1 transmits the vibration waveform signal detected by the acceleration sensor 18 or its characteristic information to all the other electronic devices 1 as information indicating the vibration state. Each electronic device 1 receives information indicating a vibration state from all other electronic devices 1 including itself, and determines the order of its own moving body based on the information indicating each vibration state. In this case, each electronic device 1 does not perform an operation of determining the order of other mobile objects or transmitting, and determines only the order of its own mobile object in a self-contained manner.

Even in such a self-contained method, as in the slave device of the second embodiment described above, each electronic device 1 instead of transmitting information indicating the vibration state detected by itself to all the other electronic devices 1. In addition, the vibration waveform of the self is analyzed to determine whether or not the step has been overcome, and when the step is overcome, a stepped signal (information indicating the passing timing) is transmitted to all other electronic devices 1 including the self. It may be.
If it is applied to such a self-contained method, it has an effect that a master device and a server device are not required.

In each of the above-described embodiments, the electronic device 1 detects the vibration transmitted when the moving body 2 gets over the step on the road surface and transmits the information indicating the passing timing, but it is not limited to the case where the moving body 2 gets over the step. For example, the vibration state transmitted when turning around a corner such as a turning point of a traveling course may be detected and information indicating a passing timing may be transmitted.

In each of the above-described embodiments, the mobile body management device 5 or the electronic device (master device) 1 transmits the ranking of the mobile body 2 to each electronic device 1, but all participating in the competition. The order of the moving body 2 may be transmitted individually to each electronic device 1. As a result, the ranking of the other mobile bodies 2 can be confirmed on each electronic device 1 side, and it can be used for bargaining in race development or for safe driving.

Further, in each of the above-described embodiments, the mobile body management table MT is accessed based on the acquired "moving body ID" and "number of times the step is overcome", and is stored corresponding to the "number of times the step is overcome". The ranking at the end is read out from the determined rankings, and the ranking itself is updated. However, the method for determining the ranking is not limited to that, and may be as follows. For example, the mobile management table MT is configured to have each item of "mobile ID", "electronic device address", "step of A waveform", "step of B waveform", ... For each mobile 2. .. That is, instead of storing the order corresponding to the "number of steps changed" as a component of the movement management table MT, the order corresponding to "~ waveform step" may be stored.

For example, when the electronic device 1 determines that it has passed a predetermined point (overcoming a step on the road surface), the electronic device 1 has information indicating the passing timing (signal with a step) and the step measured by the acceleration sensor 18. Information (vibration waveform signal or its characteristic information) indicating the vibration state of the mobile body management device 5 is transmitted. The moving body management device 5 has information indicating the vibration state of the step received from the electronic device 1 and information indicating the vibration state of the step already received and stored (vibration when the leading moving body gets over the step). The vibration waveform (waveform) that substantially matches the received vibration waveform of the step is searched for (the vibration waveform of the step that has already been stored). When the corresponding vibration waveform is found by this, it is specified that the step of the found vibration waveform corresponds to the step that has been overcome at present. The comparison of vibration waveforms is not limited to the case of comparing the waveforms themselves, and the characteristic data of the waveforms may be compared.

Then, in the moving body management table MT, the last rank may be read out from the determined ranks stored in association with the step of the specified vibration waveform, and the own rank may be updated. In this way, the correspondence relationship between the steps that each electronic device 1 has overcome can be accurately specified for each step, so that the ranking for each step can be determined more accurately. It should be noted that both the number of steps changed and the received vibration waveform may be used to specify the step that has been overcome.

In each of the above-described embodiments, as a predetermined process using the rank of the self-moving body 2, the rank of the self-moving body 2 is numerically displayed on the touch display unit 16 and the calorie consumption is calculated. Not limited to this, a process of sending a signal from the rear to the front may be performed during the platooning. In addition, when the formation is interrupted by a red light while driving on a public road, a signal may be sent to the head.

In each of the above-described embodiments, the electronic device 1 numerically displays the received self-rank, but it is not limited to the case where the received self-rank is numerically displayed, and the electronic device 1 is notified by the number of blinks or outputs a voice message. It may be notified by.

In each of the above-described embodiments, the road bike is exemplified as the moving body 2, but the vehicle is not limited to a motorcycle, another automobile, or a vehicle, and may be a human being (marathon athlete). Further, although the acceleration sensor 18 is mounted on the electronic device 1, other vibration sensors may be mounted. Further, instead of attaching the electronic device to the moving body, it may be possessed by a moving object such as a user who is moved by the moving body.

Further, in each of the above-described embodiments, the electronic device 1 is connected to the mobile management device 5 or another electronic device (master device) 1 via the smartphone 4, but the electronic device 1 is provided with a communication function. In addition, the mobile management device 5 or another electronic device (master device) 1 may be connected by communication.

In each of the above-described embodiments, the electronic device 1 exemplifies a cyclocomputer individually mounted on a plurality of moving bodies (road bikes) 2 participating in a bicycle road race, but the electronic device 1 is not limited to a dedicated machine for such competitions. For example, it may be applied to a PDA (portable information communication device for individuals) with a vibration sensor, a tablet terminal device, a mobile phone such as a smartphone, an electronic game, a music player, or the like.

Further, the "device" and "part" shown in each of the above-described embodiments may be separated into a plurality of housings according to functions, and are not limited to a single housing. Further, each step described in the above-mentioned flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or may be processed separately and independently.
