[Overview of disclosure]
By the way, it is assumed that an upper limit condition (maximum number of times of transmission or maximum amount of data to be transmitted) is set for the transmission of data permitted for a tool during a predetermined period. For example, a case where an upper limit condition is set by a contract of a network used by a tool for transmitting data, a case where a user or a maker sets an upper limit condition for the purpose of power saving or the like are assumed.

However, if the data transmission satisfies the upper limit condition, the data transmission may be restricted irrespective of whether there is a high probability that the tool will operate.

In the disclosure described below, in order to solve the above-described problem, in a case where an upper limit condition is set for data transmission, under a situation where a tool is likely to operate, the upper limit condition is satisfied and data transmission is performed. The following describes a tool, a communication device, a tool system, and a communication method that can suppress a situation in which the communication is restricted.

The power control unit 131 supplies power to the motor driving unit 140 when the driving battery 110 is attached to the tool 100 and the power switch 15 is on. The power control unit 131 does not supply power to the motor drive unit 140 when the power switch 15 is in the off state. The power control unit 131 may always supply power to the drive control unit 132 while the drive battery 110 is attached to the tool 100 (sleep state). The power control unit 131 may charge the communication battery 170 with electric power supplied from the driving battery 110 in a state where the driving battery 110 is attached to the tool 100. The power control unit 131 may manage the remaining battery level of the driving battery 110.

The communication control unit 161 controls the wireless communication unit 162. For example, the communication control unit 161 receives data from the tool control unit 130 periodically. The communication control unit 161 may manage the remaining battery level of the communication battery 170. The communication control unit 161 may periodically receive data from a position data acquisition unit 180 described below.

The wireless communication unit 162 communicates with the base station 200 provided in the network 200. For example, the wireless communication unit 162 performs wireless communication using the LPWA technology.

(4) The communication battery 170 stores power for driving the communication unit 160. For example, the communication battery 170 may be a rechargeable secondary battery. As the secondary battery, a lithium ion battery can be used.

May be included. Further, the position data acquisition unit 180 may be configured by a plurality of GNSS receivers.

(Sending data)
Hereinafter, an example of transmission data (hereinafter, simply referred to as data) according to an embodiment will be described.

For example, data transmitted from the tool 100 to the management server 300 may include first data in a use state in which the tool 100 is used, and second data in a non-use state in which the tool 100 is not used. . The first data and the second data include common data common to the first data and the second data. The first data may include individual data that is not included in the second data. The first data may be transmitted according to the operation of the tool 100.

For example, the common data includes at least one of the position data of the tool 100 and the remaining battery data. The position data of the tool 100 is data (for example, latitude and longitude data) acquired by the position data acquisition unit 180 described above. The battery remaining amount data may include data indicating the remaining battery amount of the driving battery 110, or may include data indicating the remaining battery amount of the communication battery 170.

The individual data includes at least one of the operation data of the tool 100 and the error data of the tool 100. The operation data of the tool 100 may include data indicating the number of operations of the tool 100, and may include data indicating the temperature of the tool 100. The error data of the tool 100 is data indicating an error that can be detected by the tool 100. For example, the error data may be data indicating that the rebar sandwiched by the arms of the binding unit 11 is higher than a threshold, or may be data indicating that the temperature of the tool 100 is higher than the threshold.

However, the embodiment is not limited to this, and data may not be transmitted from the tool 100 to the management server 300 in the non-use state.

In one embodiment, a case will be described in which an upper limit condition (here, the maximum number of transmissions) is set for transmission of data permitted to the tool 100 in a predetermined period. In other words, in one embodiment, it is assumed that the above-described upper limit condition is set in wireless communication using the LPWA technology.

(Communication control unit)
Hereinafter, details of the above-described communication control unit 161 will be described. As shown in FIG. 3, the communication control unit 161 has a storage unit 161A and a control unit 161B.

The storage unit 161A is an example of a storage unit that stores an operation history including the number of operation histories of the tool 100 (hereinafter, also referred to as the number of operation histories) for each unit time. For example, the storage unit 161B stores the operation history shown in FIG.

動作 As shown in FIG. 4, the operation history includes information that associates a unit time with the number of operation histories. The operation history may include information that associates the unit time with the number of communication histories (hereinafter, also referred to as the number of communication histories).

Here, a case where the time zone from 09:00 to 18:00 is the work time at the work site will be exemplified. Since the time zone from 00:00 to 09:00 is a time zone outside the working time, the number of operation histories is zero. Similarly, since the time zone from 18:00 to 00:00 is a time zone outside the working time, the number of operation histories is zero. However, when the above-described second data is transmitted, the number of communication histories may be one. On the other hand, the time zone from 09:00 to 18:00 is a time zone within the working time, and therefore the number of operation histories varies according to the operation of the tool 100. Furthermore, since it is assumed that data transmission is performed in accordance with the operation of the tool 100, the number of communication histories also changes with the change of the number of operation histories.

The storage unit 161A may store the operation history every two or more periods that can be compared with the target period. Here, the target period is a period to be subjected to an allocation process described later. The target period may be the same as the predetermined period in which the upper limit condition (here, the maximum number of data transmissions) is set. The predetermined period in which the upper limit condition is set may be, for example, one day. More specifically, one day is a period from the reference time to a time 24 hours after the reference time, and may be, for example, a period from 0:00 to 0:00 the next day. The target period may be shorter than the predetermined period. For example, the target period may be a time zone of the working time. Even in such a case, since the target period is at least a part of the predetermined period, the operation history is stored in a period that can be compared with the target period. The operation history stored in the storage unit 161A may be totaled for each predetermined period.

For example, the storage unit 161A may manage the operation history for each of two or more conditions. The two or more conditions may include an operation content using the tool 100 for a predetermined period. For example, the work content includes foundation work, demolition work, exterior work, and interior work. The two or more conditions may include an operation time using the tool 100 in a predetermined period. For example, the work time may be represented by a time length such as 8 hours, or may be represented by a time zone such as 09:00 to 18:00. The two or more conditions may include a work site using the tool 100 for a predetermined period. The work site is an identifier for identifying the work site (for example, the address of the work site, the name of the work site, the geographical coordinates of the work site, the category name for specifying the geographical division within the work site, or the management number of the work site). Or may be represented by the area of the work site. The two or more conditions may include an operator using the tool 100 for a predetermined period. The worker may be represented by a name or ID that identifies the worker. The two or more conditions may include a day of the week for a predetermined period. The two or more conditions may include a season to which the predetermined period belongs.

Here, these conditions may be managed in a format in which the operation history is tagged. The conditions for tagging the operation history may be different for each operation history. That is, there may be an operation history in which some conditions are not tagged.

The control unit 161B is an example of a control unit that controls at least the wireless communication unit 162. The control unit 161B executes an allocation process of allocating the number of data transmissions per unit time based on the operation history so that the data transmission does not satisfy the upper limit condition in the target period. The control unit 161B controls the wireless communication unit 162 so as to transmit data based on the result of the allocation process.

Specifically, since the control unit 161B can estimate the number of data transmissions assumed for each unit time in the target period based on the operation history, the control unit 161B allocates the allowable number of data transmissions for each unit time. be able to.

The control unit 161B may select a reference period to be compared with the target period from two or more periods, and execute the allocation process based on the operation history of the reference period. The control unit 161B selects a reference period that matches a condition associated with the target period. Such conditions include the work content using the tool 100 in the target period, the work time using the tool 100 in the target period, the work site using the tool 100 in the target period, the worker using the tool 100 in the target period, the day of the week in the target period. And at least one of the season to which the target period belongs.

The control unit 161B may execute the allocation process before the start of the target period. When the actual number of operations of the tool 100 in the target period is different from the history number, the control unit 161B may execute a correction process for correcting the number of times of transmission of the data allocated in the allocation process during the target period. The correction process may be performed two or more times during the target period.

Here, consider a case where the current time is time N during the target period. For example, if the actual number is less than the history number before time N, the communication history number is smaller than expected, so that the control unit 161B transmits the data allocated by the allocation process after time N. The correction process may be executed so as to reduce the number of times. According to such a correction process, unnecessary communication is suppressed, and the remaining amount of the communication battery 170 tends to be hard to decrease. According to such correction processing, it can be said that there is a tendency that the processing load for managing the tool 100 in the management server 300 can be reduced. Here, if the actual number is less than the history number before time N regardless of the upper limit condition, the tool 100 decreases the number of times of transmission of the data allocated by the allocation process after time N. May be executed. That is, the tool 100 may execute the correction process based on the operation history so as to reduce the number of data transmissions regardless of the upper limit condition described above. The tool 100 having such a configuration tends to be able to reduce the consumption of the remaining battery power of the communication battery 170 irrespective of whether the upper limit condition is set for data transmission.

Alternatively, if the actual number is less than the history number before time N, the communication history number is smaller than expected, so the control unit 161B transmits the data allocated by the allocation process after time N. The correction process may be performed so as to increase the number of times. According to such a correction process, the number of data transmissions does not exceed the maximum number of transmissions, and it is possible to prepare for an increase in the number of future communication.

Alternatively, if the actual number is greater than the history number before time N, it is assumed that the number of communication times is insufficient. Therefore, control unit 161B transmits the data allocated by the allocation process after time N. The correction process may be performed so as to increase the number of times. However, when such a correction process is performed, the number of data transmissions is likely to exceed the maximum number of transmissions. Therefore, the control unit 161B temporarily increases the number of data transmissions and then decreases the number of data transmissions. Correction processing may be performed.

(Communication method)
Hereinafter, an example of a communication method according to an embodiment will be described. Here, an example is shown in which the assignment process is executed before the start of the target period and the correction process is executed during the target period.

As shown in FIG. 5, in step S11, the tool 100 executes an allocation process of allocating the number of data transmissions per unit time based on the operation history so that the data transmission does not satisfy the upper limit condition in the target period. . Details of the allocation process are as described above.

In step S12, the tool 100 transmits data to the management server 300 based on the result of the assignment processing.

In step S13, the tool 100 executes a correction process for correcting the number of times of transmission of the data allocated in the allocation process during the target period. Details of the correction processing are as described above.

In step S14, the tool 100 transmits data to the management server 300 based on the result of the correction processing.

FIG. 5 illustrates a case where one correction process is performed, but the correction process may be performed two or more times as described above.

The tool 100 according to one embodiment executes the correction process without depending on the value of the battery remaining amount, if the communication battery 170 has a sufficient remaining battery level to execute the above-described correction process. May be.

(Action and effect)
In one embodiment, the tool 100 performs an assignment process of allocating the number of data transmissions per unit time based on the operation history so that the data transmission does not satisfy the upper limit condition in the target period. According to such a configuration, in a case where the upper limit condition is set for data transmission, data transmitted from the tool 100 is not easily limited. In other words, in the case where the upper limit condition is set for data transmission, the tool 100 suppresses a situation in which the upper limit condition is satisfied and the data transmission is restricted under a situation where the tool is likely to operate. Can be.

[Example of change]
Hereinafter, a modification of the embodiment will be described. Hereinafter, differences from the above-described embodiment will be described.

Specifically, in the above-described embodiment, the case where the communication unit 160 and the communication battery 170 are built in the tool 100 has been described. On the other hand, in the modified example, as shown in FIG. 6, the communication device 400 including the communication unit 160 and the communication battery 170 is configured to be detachable from the tool 100.

As shown in FIG. 6, the communication device 400 has a connection portion 191 for electrically connecting to the tool 100 driven by power supplied from the detachable drive battery 110. On the other hand, the tool 100 has a connecting portion 192 for electrically connecting to the connecting portion 191 of the communication device 400.

The communication device 400 has at least the communication unit 160 described above. The communication device 400 may include the communication battery 170 described above. Since the communication unit 160 and the communication battery 170 have the same configuration and function as those of the above-described embodiment, the details are omitted. In such a case, the communication device 400 may acquire, from the tool 100, data necessary for transmitting the first data and the second data.

As described above, since the communication device 400 including the communication unit 160 and the communication battery 170 is configured to be detachable from the tool 100, the communication function is provided to the tool 100 as necessary after the user purchases the tool 100. Can be added. Further, even when the communication unit 160 or the communication battery 170 has failed or deteriorated over time, the communication device 400 can be easily replaced.

In FIG. 6, the power control unit 131 is provided in the tool 100, but a part or all of the functions of the power control unit 131 may be realized by the communication device 400. In other words, the communication device 400 may execute the function of the power control unit 131 by itself, or may execute the function of the power control unit 131 in cooperation with the tool control unit 130 of the tool 100.

Specifically, in the above-described embodiment, the case where the upper limit condition defined for data transmission is the maximum number of data transmissions in a predetermined period has been exemplified. On the other hand, in the modified example, the upper limit condition set for data transmission is the maximum transmission data amount in a predetermined period.

In the modification, the details of the allocation process and the correction process are the same as those in the above-described embodiment, and the above-mentioned “number of transmissions” may be read as “the amount of transmission data”.

In the modified example, the control unit 161B executes the assignment process based on the learning result of the operation history. The learning of the operation history may be performed by the tool 100, or may be performed by a server such as the management server 300. When the server learns the operation history of the tool 100, the tool 100 and the server may share the operation history of the tool 100 and the learning result by the server through communication.

For example, the learning may be a process of calculating an average value of the number of operation histories for each condition. The condition may be two or more conditions selected from the content of work, work time, work site, worker, day of the target period, season to which the target period belongs, and the like.

学習 Alternatively, the learning may be a process realized by artificial intelligence. Specifically, in the learning, the execution intelligence specifies the operation history using the above-described conditions as input conditions, and the artificial intelligence estimates the number of operations of the tool 100 per unit time in the target period based on the specified operation history. It may be processing. The tool 100 may feed back the evaluation of the estimation result to the artificial intelligence. The evaluation of the estimation result may be such that the number of operations estimated by artificial intelligence is smaller than the actual number, or the number of operations estimated by artificial intelligence is larger than the actual number.

In such a case, the tool 100 may include a notification interface 17 for notifying the progress of learning of the operation history (hereinafter, also simply referred to as the progress of learning), as shown in FIG. The tool 100 may determine the progress of the learning using a known technique.

The notification interface 17 may be a display provided on the tool 100 or a light emitting element such as an LED. For example, the tool 100 may display, on a display, a character, graphic, or symbol indicating that the progress of learning the operation history has satisfied a predetermined condition. For example, the tool 100 may issue an LED of a color indicating that the progress of learning has satisfied a predetermined condition. For example, the tool 100 may cause the LED to blink in a blinking pattern indicating that the progress of learning of the operation history satisfies a predetermined condition. The notification interface 17 may be a sound output device such as a speaker provided on the tool 100. For example, the tool 100 may output a sound or a buzzer sound from a speaker indicating that the learning progress condition has satisfied a predetermined condition. The notification interface 17 may be a communication interface that transmits data indicating the progress to an external device (for example, the user terminal or the management server 300). In such a case, the communication unit 160 described above may be used as the notification interface 17.

工具 Here, the tool 100 may have a learning control unit 133 as shown in FIG. The learning control unit 133 may notify the progress of learning the operation history when the learning progress satisfies a predetermined condition. For example, the predetermined condition may be that a predetermined learning result is accumulated.
