The battery C28, in one example, is provided in the frame of the human-powered vehicle B. Battery C28 contains secondary batteries. The battery C28 is connected to a plurality of components C by a power line E. The plural components C are driven by the electric power supplied from the battery C28.

(Send of update information) The maintenance device 10 sends a signal containing the update information U to the module C through the communication unit 16 to perform the repair of the module C. That is, the component C receives a signal containing update information U from the repairing device 10, and updates its own firmware by the received update information U to perform repairs. That is, the update information U is the information including the new version of the firmware, in other words, the update information of the firmware. However, the update information U only needs to be information for changing at least one of the configuration of the component C and the firmware of the component C. Hereinafter, the sending of the update information U from the maintenance device 10 will be explained.

Initially, the maintenance device 10 and the input terminal 30 are connected by the communication cable D. Next, the power supply of the input terminal 30 is set to ON, and the maintenance program is executed by the control unit 32 of the input terminal 30. The communication unit 36 of the input terminal 30 uses this program to send basic update information for updating the firmware of the component C to the maintenance device 10. The basic update information is stored in the storage unit 34 of the input terminal 30 in advance. The basic update information is information for changing at least one of the settings of the component C and the firmware of the component C, and the information contained in the entirety of the information. The maintenance device 10 divides the basic update information into plural update information U in order to be able to deal with the large amount of data of the basic update information or the maintenance of the plural components C, for example. The maintenance device 10 divides the divided update information U into multiple ways of time division, that is, from different time points, and sends messages to the component C in sequence. Hereinafter, the method of transmitting the divided update information U will be explained.

Figure 3 is a diagram showing an example of a time slot. The control unit 12 of the maintenance device 10 divides the signal sent to the component C into a plurality of cycles T, and divides one cycle T into a predetermined number of time slots S. The time slot S is a slot containing one update information U or one time synchronization information V described later, that is, the length of time. In other words, the signal sent from the maintenance device 10 to the component C is sent from one time slot S, one update information U, or one time synchronization information V described later. The control unit 12 includes different update information U or time synchronization information V in each time slot S. In other words, the control unit 12 controls the communication unit 16 by distributing information into a plurality of time slots S to transmit. However, the time slot S may not include any of the update information U and the time synchronization information V. That is, the signal sent from the maintenance device 10 to the component C may include the time slot S in which the information is not allocated.

The time slot S is a preset time length, but will correspond to the information contained, so that the time length becomes different. That is, the time slot S to which the update information U is allocated, the time slot S to which the time synchronization information V is allocated, and the time slot S to which the information is not allocated, that is, the time slot S to which the update information U and the time synchronization information V are not allocated. The length of time is different from each other. Therefore, the time length of the period T also corresponds to the time length of the time slot S and is different. The details of the time length of each time slot S will be described later.

In the example of Fig. 3, the control unit 12 sets 31 time slots S (time slots S1 to S31) in one cycle T. That is, in the example of this embodiment, the number of time slots S in one period T, that is, the predetermined number, is 31. The control unit 12 sets the time slot S in such a way that the signal is sent from the time slot S1, S2 ‧ ‧ S31 to the component C in the order of each time. Also, after the time slot S31, there is a time slot S1 that becomes the next cycle, and thereafter is the sequence of becoming the same time slot. However, the number of time slots S in one cycle T is not limited to 31, and it can be arbitrary if the number is plural.

Figure 4 is a diagram showing an example of time synchronization information. As shown in FIG. 4, the control unit 12 allocates the time synchronization information V to the first time slot S of the period T, that is, the time slot S1. The time synchronization information V is information for synchronizing the pulse of the maintenance device 10 (communication unit 16) and the pulse of the component C, in other words, a pulse signal. The control unit 12 generates plural time synchronization information V, and allocates each time synchronization information V to the time slot S1 of each cycle T. In Figure 4, the plural time synchronization information V includes the first time synchronization information V1 and the second time synchronization information V2. The control unit 12, in Figure 4, contains the first time synchronization information V1 as the time synchronization information V in the time slot S1 of the first cycle T, and in the time slot S1 of the first cycle T (the first time synchronization The subsequent time slot S1) of the information V1 contains the second time synchronization information V2 as the time synchronization information V. In the subsequent period T, the time slot S1 also contains the time synchronization information V as required.

In this way, the control unit 12 allocates the synchronization information V of each time to the time slot S1 of each cycle T. Therefore, it can be said that the control unit 12 starts from the time point (time slot S1) when the time synchronization information V (the first time synchronization information V1 in Figure 4) is sent to the next time synchronization information V (In Figure 4, the second time synchronization information V2) is sent to the eve of the time point (time slot S1), set as a cycle T, from the time point when the synchronization information V is sent to A predetermined number of time slots S (here 30) are set for the time between the eve of the time point when the synchronization information V is sent at the next time. Furthermore, in this embodiment, as shown in FIG. 4, in the time slot S1, after the time when the time synchronization information V is signaled, the time for buffering is set. However, the buffer time may not be set.

Fig. 5 is a diagram showing an example of update information. Figure 5 is an example of a case where the update information U is sent to one component C. The control unit 12 allocates the update information U in the time slot S between one time synchronization information V and the next time synchronization information V, here it is between the first time synchronization information V1 and the second time synchronization information V2 The time slot S. The update information U may include various information. In this embodiment, it includes destination information and individual update information.

The control unit 12 generates destination information based on the basic update information. The destination information is to display: the update information U including the destination information is the information of the person making the component C the target, that is, the information of the person making the component C the destination. Therefore, the destination information includes information corresponding to the identification information assigned to the component C. The control unit 12 obtains the basic update information from the input terminal 30 for which component C is the target information, and generates the information of the component C that is the target of the basic update information as destination information. In addition, if component C receives destination information, compare the destination information with the identification information assigned to it, when the component C specified by the destination information and the component C specified by the identification information are the same. , It can be recognized that the update information contained in the destination information is the update information corresponding to itself. It is recognized that when the update information included in the destination information of the component C corresponds to the update information of the component C, the reception confirmation information that the update information U has been received is displayed, and a message is sent to the maintenance device 10.

The individual update information is information in which the basic update information is divided into plural numbers. In other words, individual update information is information that contains a part of the basic update information, and the basic update information can be reproduced by collecting the overall score of the individual update information. The control unit 12 generates individual update information by dividing the basic update information into a plurality of individual update information. In the plural individual update information, each is assigned a different division number.

The control unit 12 generates one piece of update information U as one piece of update information U: destination information and one piece of individual update information generated separately. In addition, the control unit 12 generates the destination information of the same destination and the other piece of separate update information generated separately as the other piece of update information U. In other words, the control unit 12 generates plural update information U by linking and relating common destination information to the divided individual update information. Furthermore, when the component C to be repaired is plural, the control unit 12 generates plural update information U for each component C.

As shown in FIG. 5, the control unit 12 distributes the update information U generated in this way in the time slot S between one time synchronization information V and the next time synchronization information V. In more detail, the control unit 12 sets the reception acceptance time in the time slot S to which the update information U is allocated, and in the time frame after the update information U. The reception acceptance time is the time set in order to receive the reception confirmation information for displaying the update information received from the component C. That is, if the maintenance device 10 transmits the update information U, it displays the reception confirmation information for receiving the update information U, and receives the information from the time in the same time slot S as the update information U. The control unit 12 allocates the destination information, the individual update information, and the reception acceptance time in the time slot S to which the update information U is allocated, in this order. That is, the control unit 12 sends the destination information first in the time slot S to which the update information U is allocated, then sends the individual update information, and then sends the reception confirmation information. That is, the control unit 12 is configured to: update information U (first update information U1), and the reception confirmation time for receiving the update information U from the assembly C of the human-powered vehicle B (first reception confirmation) Time), the communication unit 16 is controlled by assigning the same time slot S. In addition, the control unit 12 sets the time for buffering before and after the reception acceptance time. Furthermore, although the control unit 12 is not shown in the figure, a buffering time may be set between the destination information and the individual update information. However, the buffer time may not be set.

As mentioned above, the time slot S containing the update information U, the time slot S containing the time synchronization information V, and the time slot S not containing the information have different time lengths. Here, the time slot S that does not contain information, that is, the time length of the time slot S that is not included in the update information U and the time synchronization information V, is set to the time length t0. Moreover, the time length of the time slot S (time slot S1) containing the time synchronization information V is set to the time length t1. In addition, the time length of the time slot S (the time slots S5, S20, and S10 in the example of FIG. 5) containing the update information U is set to the time length t10. In this case, the time length t1 of the time slot S1 to which the time synchronization information V is allocated is different from the time length t10 of the time slot S5 to which the update information U is allocated. Further, the time length (time length t1 or time length t10) of any allocated time slot of the time synchronization information V and the update information U is the time slot S that is not allocated to the time synchronization information V and the update information U The length of time t0 is different. Specifically, the time length t0 is shorter than the time length t1, and the time length t1 is shorter than the time length t10. In other words, the time length t1 of the time slot S1 to which the time synchronization information V is allocated is smaller than the time length t10 of the time slot S5 to which the update information U is allocated. Moreover, the time length t0 of the time slot S in which the time synchronization information V and the update information U are not allocated is greater than the time slot allocated for any one of the time synchronization information V and the update information U (time slot S1 or time slot S5). The time length (time length t1 or time length t5) of) is smaller. In summary, the time length t1 of the time slot S1 where the time synchronization information V is allocated is smaller than the time length t5 of the time slot S5 where the update information U is allocated, and the time slots where the time synchronization information V and the update information U are not allocated The time length t0 of S is smaller than the time length t1 of the time slot S1 where the time synchronization information V is allocated. In addition, the time length t1 is preferably not shorter than the time length t10, and the length may be different from the time length t10. For example, the time length t1 may be longer than the time length t10. In addition, the time length t1 may be the same length as the time length t10. Moreover, the time length of the allocated time slot S of the time synchronization information V and the update information U, and the time length t0 of the time slot S where the time synchronization information V and the update information U are not allocated are different lengths from each other. That's it.

In the time slot S containing the update information U, in addition to the update information U, the reception acceptance time is set. Hereinafter, the time length for the update information U to be allocated is set to the time length t12, and the time length other than the time length t12 for the update information U in the time slot S containing the update information U is set to the time length t14. In the example of this embodiment, the time length t12 and the time length t14 are different, the time length t12 is greater than the time length t14, and the relationship between the time length t12 and the time length t14 is arbitrary.

In the example of this embodiment, the time length t0 is 16 microseconds, the time length t1 is 49 microseconds, and the time length t10 is 234 microseconds. Moreover, the time length t12 is 128 microseconds, and the time length t14 is 106 microseconds. However, the values of the lengths of time lengths t0, t1, t10, t12, and t14 are not limited to these. In addition, although the time synchronization information V is set in plural, the time length t1 of the time slot S to which the time synchronization information V is allocated is the same for all the time synchronization information V. Similarly, for all the update information U, the time length t10 of the time slot S to which the update information U is allocated becomes the same.

Here, the control unit 12 includes plural update information U in time slots S different from each other. The control unit 12 is the update information U for the same destination information, that is, the update information U for the same component C, so that the interval between the first update information U and the subsequent update information U sent out becomes a prescribed For the method above time, set the time slot S to which the update information U is allocated. In more detail, the control unit 12 is for the update information U of the same destination information so that the time length t20 from the completion of the transmission of the first update information U to the start of the transmission of the next update information U, It is a method that is longer than a predetermined time and sets the time slot S to which the update information U is allocated. Here, the predetermined time is preferably 200 microseconds (μsec) or more, preferably 400 microseconds or less. For further explanation, the prescribed time is 250 microseconds or more, and more preferably 340 microseconds or less. However, the length of the predetermined time can be set arbitrarily.

Fig. 5 shows an example in which, for the update information U of one component C, the first update information U1, the second update information U2, and the third update information U3 are sent. The first update information U1 has the first destination information U11 and the first individual update information U12, the second update information U2 has the second destination information U21 and the second individual update information U22, and the third update information U3. It has the third destination information U31 and the third individual update information U32. The first update information U1, the second update information U2, and the third update information U3 are the same destination. It can be said that the plural update information U includes the first update information U1 and the second update information U2 with the same destination as the first update information U1. Furthermore, it can be said that the plural update information U includes the second update information U2 and the third update information U3 having the same destination as the second update information U2. Furthermore, it can be said that the plural update information U includes the first update information U1 and the third update information U3 having the same destination as the first update information U1. That is, the first update information U1, the second update information U2, and the third update information U3 target the same component C. In addition, the first individual update information U12, the second individual update information U22, and the third individual update information U32 are those that divide the basic update information for the same component C, and include information on different parts of the basic update information. That is, the first update information U1 includes the first destination information U11 corresponding to the component C and the first individual update information U12 applied to the component C. In addition, the second update information U2 includes the second destination information U21 corresponding to the component C and the second individual update information U22 applied to the component C. The first destination information U11 and the second destination information U12 are the same. In addition, the second update information U2 includes the second destination information U21 corresponding to the component C and the second individual update information U22 applied to the component C. In addition, the third update information U3 includes the third destination information U31 corresponding to the component C and the third individual update information U32 applied to the component C. The second destination information U21 and the second destination information U32 are the same. In addition, the first update information U1 includes the first destination information U11 corresponding to the component C and the first individual update information U12 applied to the component C. In addition, the third update information U3 includes the third destination information U31 corresponding to the component C and the third individual update information U32 applied to the component C. The first destination information U11 and the third destination information U32 are the same.

In the example of Fig. 5, the control unit 12 allocates the first update information U1 to the time slot S5, the second update information U2 to the time slot S20, and the third update information U3 to the time of the next cycle T Slot S10. The length of time from the completion of the transmission of the first update information U1 to the start of the transmission of the second update information U2, and the length of time from the completion of the transmission of the second update information U2 to the start of the transmission of the third update information U3 , Is more than the prescribed time. That is, the control unit 12 sets the time slot S of the first update information U1 and the second update information U1 so that the time between the transmission of the first update information U1 and the transmission of the second update information U2 becomes a predetermined time or more. The number of time slots S between the time slots S of the update information U2 is set. In addition, the control unit 12 changes the time slot S of the second update information U2 and the third update information U2 so that the time between the transmission of the second update information U2 and the transmission of the third update information U3 becomes a predetermined time or more. The number of time slots S between the time slots S of the update information U3 is set.

In this way, the control unit 12 is a signal sent to the component C, including the time synchronization information V and the update information U. The control unit 12 sends the signal generated in this way to the component C via the communication unit 16. Therefore, in the example of Fig. 5, toward component C, from the sequence of the first time synchronization information V1, the first update information U1, the second update information U2, the second time synchronization information V2, and the third update information U3, Information is sent. In addition, the time between the first update information U1 and the second update information U2, and the time between the second update information U2 and the third update information U3 are equal to or more than a predetermined time.

In other words, the control unit 12 sends the plural time synchronization information V and the plural update information U in the order of the first time synchronization information V1, the first update information U1, the second update information U2, and the second time synchronization information V2. The way, the communication unit 16 is controlled. In addition, the control unit 12 controls the communication unit 16 so that the transmission interval of the first update information U1 and the second update information U2 becomes a predetermined time or more. To further explain, the control unit 12 sets the time slot S (here, the time slot) to which the first update information U1 is allocated so that the transmission interval of the first update information U1 and the second update information U2 becomes a predetermined time or more. The communication unit 16 is controlled by the number of time slots S between the slot S5) and the time slot S (here, the time slot S20) to which the second update information U2 is allocated. To further explain, the control unit 12 sets the time interval (time length t20) from the completion of the transmission of the first update information U1 to the start of the transmission of the second update information U2 to a predetermined time or more. 1 The time slot S between the time slot S allocated to the update information U1 (here, time slot S5) and the time slot S to which the second update information U2 is allocated (here time slot S20). 16 control.

In addition, it can be said that the control unit 12 combines the plural time synchronization information V and the plural update information U in the order of the first time synchronization information V1, the second update information U2, the second time synchronization information V2, and the third update information U3. The way of sending the message is controlled by the communication unit 16. In addition, the control unit 12 controls the communication unit 16 so that the transmission interval of the second update information U2 and the third update information U3 becomes a predetermined time or more. More specifically, the control unit 12 controls the communication unit 16 so that the transmission interval of the second update information U2 and the third update information U3 becomes a predetermined time or more. To further illustrate, the control unit 12 sets the time slot S to which the second update information U2 is allocated (here, the time slot S20) and the time slot S to which the second update information U2 is allocated (here, the time slot S of the next cycle T). The time slots S between the time slots S10) are controlled by the communication unit 16 in number. To further explain, the control unit 12 sets the first time interval (time length t20) from the completion of the transmission of the second update information U2 to the start of the transmission of the third update information U3 to a predetermined time or more. 2 The number of time slots S between the time slot S assigned to the update information U2 (here, time slot S20) and the time slot S assigned to the third update information U3 (here, the time slot S10 of the next cycle T) Ground, the communication unit 16 is controlled.

It can also be said that the control unit 12 is to combine the plural time synchronization information V and the plural update information U in the order of the first time synchronization information V1, the first update information U1, the second time synchronization information V2, and the third update information U3. The way of sending the message is controlled by the communication unit 16. Also, the number of time slots S between the time slot S1 to which the first time synchronization information V1 is allocated and the time slot S (here, time slot S5) to which the first update information U1 is allocated, and the second time synchronization information V2 The time slot S between the allocated time slot S (here, the time slot S1 of the next cycle T) and the time slot S where the third update information V3 is allocated (here, the time slot S10 of the next cycle T) The number is different.

Fig. 6 is a diagram showing another example of update information. In Fig. 5, in time slots S5, S20, and S10, first update information U1, second update information U2, and third update information U3 are allocated respectively. However, the control unit 12 is not limited to the distribution method shown in FIG. 5 if the time length between each update information U is a predetermined time or longer. For example, the control unit 12, as shown in Fig. 6, sets the time length between the update information U to be as small as possible (the smallest method) in order to satisfy the condition of being longer than a predetermined time, and set the update information The number of time slots S between U and each other can also be used. That is, in the example in Figure 6, for example, the first update information U1 is allocated in time slot S5, the second update information U2 is allocated in time slot S12, and the third update information U3 is allocated in time slot S12. In the time slot S19, the fourth update information U4 is allocated in the time slot S, and the fifth update information U5 is allocated in the time slot S2 of the next cycle T. The fourth update information U4 and the fifth update information U5 are the same destinations as the first destination information U11, the second destination information U21, and the third destination information U31. 2 The update information U2 and the third update information U3 also use the same component C as the update information U.

In Figure 6, the time length t20 from the completion of the transmission of the first update information U1 to the start of the transmission of the second update information U2 is because the time length t14 and the time slot S6 from which the information is not allocated are changed to The time length of S11 is added, so it becomes 212 microseconds. Similarly, the length of time from the completion of the transmission of the second update information U2 to the start of the transmission of the third update information U3, and from the completion of the transmission of the third update information U3 to the start of the transmission of the fourth update information U4 The length of time becomes 212 microseconds. And, the time length from the completion of the transmission of the fourth update information U4 to the start of the transmission of the fifth update information U5 is: the time length t14 and the time length from the time slots S27 to S31 where the information is not allocated , And the time slot S1 of the second time synchronization information V2, so it becomes 235 microseconds. In this way, in the example in Fig. 6, the time length between the update information U is set to be at least a predetermined time (in this case, 200 microseconds or more) and to be the minimum. The number of time slots S.

Fig. 7 is a diagram showing an example of update information. Figures 5 and 6 are examples of the case where the update information U is sent for one component C, but Figure 7 is an example of the case where the update information U is sent for a plurality of components C. Figure 7 illustrates that the update information Ua is sent to the first element (the first element of the human-powered vehicle) among the plurality of elements C, and the update information Ub is sent to the second element (the second element of the human-powered vehicle). News, the third component (the third component of the human-powered vehicle) will update the information Uv, the fourth component (the fourth component of the human-powered vehicle) will update the information Ud, and the fifth component (the human-powered vehicle) will update the information Uv. The fifth component) will update the information Ue sending example. In this way, in the example of FIG. 7, although the command to send the update information U to the five components C is displayed, the number of the components C that send the update information U is arbitrary.

For further explanation, as illustrated in Figure 7, the first update information U1a, the second update information U2a, and the sixth update information U6a are sent to the first component, and the first update information U1b, The second update information U2b, ‧‧‧ the sixth update information U6b, the first update information U1c, the second update information U2c, and the sixth update information U6c are sent to the third component, and the sixth update information U6c is sent to the fourth component. The first update information U1d, the second update information U2d, and the sixth update information U6d are sent, and the first update information U1e, the second update information U2e, and the sixth update information U6e are sent toward the fifth component.的例。 Examples. The control unit 12 allocates the first update information U1a with the first component as the destination in the time slot S2, allocates the first update information U1b with the second component as the destination in the time slot S3, and allocates the first update information U1b with the second component as the destination in the time slot S4. The first update information U1c with the third component as the destination is assigned, the first update information U1d with the fourth component as the destination is allocated in the time slot S5, and the first update information U1d with the fifth component as the destination is allocated in the time slot S6. 1Update information U1e. In addition, the control unit 12 allocates the second update information U2a with the first component as the destination in the time slot S7, and allocates the second update information U2b with the second component as the destination in the time slot S8. S9 assigns the second update information U2c with the third component as the destination, the second update information U2d with the fourth component as the destination in the time slot S10, and the fifth component as the destination in the time slot S11 The second update information U2e.

In this way, the control unit 12 sends the update information U to the plural components C, sends the first update information to each component C in order, and sends the first update information to all the components C. The second update signal is sent to each component C in sequence, and it is repeated. In other words, the control unit 12 allocates the time slot S between the time slot S to which the update information U is allocated and the time slot S to which the update information of the same destination is allocated, and allocates the update with the other component C as the destination. Information U. In addition, the control unit 12 sets the time length t20 between the update information of the same destination in all of the update information Ua, the update information Ub, the update information Uc, the update information Ud, and the update information Ue to a predetermined time. the above.

In this way, when the update information U is sent to the plurality of components C, the time slot S of the update information U with the other components C as the destination is set between the update information U. On the other hand, when the update information U is sent to one component C, the update information U is not allocated in the time slot S between the update information U. Therefore, when the update information U is sent to a plurality of components C, the time slot S between the update information U is longer than that when the update information U is sent to one component C. Therefore, the control unit 12 can compare the number of time slots S between the update information U to the case where the update information U is sent to one unit C when the update information U is sent to the plural components C. More reduction. That is, when the time slots S between the update information U include information, the number of time slots S between the update information U can be reduced. In the example of FIG. 7, all of the time slots S between the update information U of the same destination are allocated the update information U of another destination, or the time synchronization information V. That is, in the example of FIG. 7, in the time slot S between the update information U, there is no time slot S in which the information is not allocated. However, when the update information U is sent to the plural component C, the time slot S between the update information U may include the time slot S where the information is not allocated.

The control unit 12, after the time slot S11, similarly sends the update information U to each component C in sequence. In the example of Fig. 7, the first component with the first component as the destination is allocated in the time slot S27. 6 Update information U6a, the sixth update information U6b with the second component as the destination is allocated in the time slot S28, the sixth update information U6c with the third component as the destination is allocated in the time slot S29, and the sixth update information U6c with the third component as the destination is allocated in the time slot S30 The sixth update information U6d with the fourth component as the destination is assigned, and the sixth update information U6e with the fifth component as the destination is allocated in the time slot S31.

In this way, the component C includes a first component (a first component of a human-powered vehicle) and a second component (a second component of a human-powered vehicle) that is different from the first component. In addition, the plural update information U includes: the first update information U1a and the second update information U2a whose destination is the first component, and the additional first update information (the first update information U1b) whose destination is the second component . The control unit 12 allocates the added first update information (first update information U1b) to the time slot S (time slot S2 in the example of FIG. 7) where the first update information U1a is allocated, and the second The communication unit 16 is controlled by the time slot S (time slot S3 in the example of FIG. 7) between the time slots S (time slot S7 in the example of FIG. 7) to which the update information U2a is allocated. In addition, the plural update information U further includes additional second update information (second update information U2b) whose destination is the second component. The control unit 12 sets the time slot S to which the second update information U2a is allocated so that the transmission interval of the added first update information U1b and the second update information U2b becomes a predetermined time or more (in Fig. 7 In the example, the time slot S3) and the time slot S to which the second update information U2b is allocated (the time slot S8 in the example of FIG. 7) are controlled by the communication unit 16 according to the number of time slots.

The control unit 12, as described above, allocates the update information U to the time slot S, and sends a signal to the component C. Component C receives the update information U in sequence. If all the update information U is received, the basic update information is reproduced, and the firmware is updated based on it. As a result, the maintenance of the component C is completed.

(Maintenance flow) 　　 Below, the maintenance flow of component C will be explained in accordance with the flowchart. Initially, the control flow of the input terminal 30 will be explained. Fig. 8 is a flowchart showing an example of the control flow performed by the input terminal. The control unit 32 of the input terminal 30 is a user interface (not shown) provided in the input terminal 30, and operations required for the execution of the corresponding program are input, and the control (program) is started.

The control unit 32 acquires the identification information of the component C (step S100), and stores it in the storage unit 34. After that, the control unit 32 obtains the version information of the firmware of the component C and stores it in the memory unit 34 (step S102). The control unit 32 executes step S100 and step S102 for all the components C, and obtains the identification information and version information of all the components C.

After obtaining the identification information and version information, the control unit 32 determines whether the firmware update is necessary for the component C (step S104). In one example, the control unit 32 determines whether the latest version information of the firmware stored in the memory unit 34 in advance and the obtained version information of the firmware are consistent. The control unit 32 determines that the latest version information of the firmware stored in the memory unit 34 in advance and the obtained version information of the firmware are inconsistent, and it is determined that the firmware update for the component C is necessary. On the other hand, the control unit 32, when the latest version information of the firmware stored in the memory unit 34 in advance and the obtained version information of the firmware are consistent, determines that the firmware update for the component C is unnecessary.

If the control unit 32 does not have the component C necessary for the firmware update (step S104; No), this process is terminated. In one example, at the end of this process, it is displayed that all the components C are information outside the object of update, and are displayed on the display section 40 of the input terminal 30. The control unit 32, when the firmware update is necessary for the component C (step S104; Yes), acquires the basic update information used for the firmware update of the component C, which is necessary for the firmware update. The update information is linked to the identification information of the component C (step S106). If the basic update information and identification information are linked, the control unit 32 sends the basic update information and identification information related to the link to the maintenance device 10 (step S108). In addition, the control unit 32 determines whether all the information related to the connection (basic update information and identification information) has been sent to the maintenance device 10 (step S110), if all information has not been sent (step S110; No) , Return to step S108 and continue to send the message, if all the messages have been sent (step S110; Yes), this process is terminated.

In this way, the input terminal 30 is to link the identification information and the basic update information and send a message to the maintenance device 10.

Fig. 9 is a flowchart illustrating an example of the control flow of the maintenance device. As shown in Fig. 9, the control unit 12 of the maintenance device 10 obtains the link-related information sent from the input terminal 30, that is, the basic update information and identification information related to the link (step S130), and stores it in the memory部14. In addition, the control unit 12 generates plural update information U from the acquired basic update information and identification information (step S132). Specifically, the control unit 12 divides the basic update information into plural pieces to generate individual update information, and generates destination information from the identification information. In addition, the control unit 12 links the common destination information for each individual update information to generate plural update information U. The control unit 12 performs this for all the components C, and generates plural update information U for each component C. When the update information U is generated, the control unit 12 generates the time synchronization information V (step S134). However, the order of the generation of the time synchronization information V and the generation of the update information U is not limited to this, and can be arbitrary.

When the time synchronization information V and the update information U are generated, the control unit 12 allocates the time synchronization information V and the update information U to the time slot S (step S136). The control unit 12 allocates the time synchronization information V to the first time slot S1 of the period T, and sets the number of time slots S between the time slots S1 of the time synchronization information V. In addition, the control unit 12 allocates the update information U to the time slot S between the time slots S1 of the time synchronization information V. The control unit 12 sets the time slot S to which the update information U is allocated so that the time interval (time length t20) between the transmission time points of the update information U of the same destination becomes a predetermined time or more.

If the time synchronization information V and the update information U are allocated to the time slot S, the control unit 12 controls the communication unit 16 and sends the signal containing the time synchronization information V and the update information U to the sequence of the time slot S that is set. Component C sends the signal. The control unit 12 sends a signal including the time synchronization information V and the update information U to all the components C (step S138). In addition, the control unit 12 determines whether all the update information U has been sent (step S140). If all the update information U has not been sent (step S140; No), it returns to step S138 to continue sending the message. When all the update information U is sent (step S140; Yes), this process is terminated.

In this way, the maintenance device 10 sends the plural update information U to the component C in the order of the set time slot S.

Fig. 10 is a flowchart illustrating an example of the control flow of the component. As shown in Figure 10, the control unit C1 of the component C judges whether a signal is received from the maintenance device 10 (step S150). If the signal is not received (step S150; No), return to step S150 and continue processing . When the control unit C1 receives a signal (step S150; Yes), it judges whether the time synchronization information V is received (step S152), that is, whether the received signal includes the time synchronization information V. When the time synchronization information V is received (step S152; Yes), the control unit C1 executes processing corresponding to the time synchronization information V (step S154). The control unit C1, whose processing corresponding to the time synchronization information V uses the time synchronization information V, matches the pulse of the control unit C1 with the pulse of the communication unit 16 of the maintenance device 10.

When the time synchronization information V has not been received (step S152; No), or if the processing corresponding to the time synchronization information V has been executed, the control unit C1 judges whether the update information U has been received, that is, whether the signal contains update information U(Step S156). If the update information U has not been received (step S156; No), return to step S150 and continue to receive the signal. When the update information U is received (step S156; Yes), the control unit C1 determines whether the destination information included in the update information U matches its own identification information (step S158). If the destination information does not match the identification information (step S158; No), return to step S150 and continue the signal reception. When the destination information matches the identification information (step S158; Yes), the control unit C1 sends the reception confirmation information to the maintenance device 10, and stores the update information U in the storage unit C2 (step S160). That is, the control unit C1 sends the received update information U to the maintenance device 10 for its own situation, sends the received update information U, and saves the received update information U, if it is further explained. In the memory section C2. The control part C1 temporarily stores the received update information U in the temporary memory of the memory part C2. If the amount of information in the temporary memory reaches a predetermined amount, it will be stored in the information memory of the temporary memory. In main memory. By executing this process, the firmware stored in the main memory is partially updated. The update information U stored in the temporary memory is erased.

After that, the control unit C1 judges whether the last update information U has been received (step S162), and if the last update information U has not been received (step S162; No), it returns to step S150 and continues processing. The control unit C1 is the case where the last update information U is received (step S162; Yes). For example, if the update information U stored in the memory unit C2 in step S160 includes a mark showing the last update information U, the control Part C1 is the end of this process. In one example, the information indicating the completion of the firmware update at the end of the program is displayed on the display section 40 of the input terminal 30.

As explained above, the maintenance device 10 of the present embodiment sets the update information U to be set to the time interval (time length t20) at which the update information U of the same destination is sent to be longer than a predetermined time. The allocated time slot S. Therefore, because the maintenance device 10 allows the component C to obtain the update information U at a sufficient time interval, it can efficiently send the update information U to the component C of the manpower-driven vehicle B.

In addition, the communication method of the maintenance device 10 and the input terminal 30 can be arbitrarily changed. In the first example, the maintenance device 10 and the input terminal 30 communicate wirelessly. In this case, the input terminal connection part 20 and the maintenance device connection part 38 are omitted, and the communication part 16 and the communication part 36 include a wireless communication part. In the second example, the maintenance device 10 and the input terminal 30 communicate via the Internet. In this case, the input terminal 30 can be the server of the cloud computing system.

In addition, the communication method of the maintenance device 10 and the plurality of components C can be arbitrarily changed. In the first example, the maintenance device 10 and the plurality of components C are wireless communication. In this case, the connection parts 18 and C4 are omitted, and the communication part 16 of the maintenance device 10 and the communication part C3 of the plural components C include a wireless communication part. In the second example, the maintenance device 10 and the plurality of components C communicate through a communication method that is not suitable for power line communication.
