The generated dynamic information is, for example, in a predetermined format. As a mand, the drive control unit 22 connects to the second wiring board 42PCB via the first connection unit 41CN. It is supplied to the communication control unit 34.

[0105] (S204) The communication control unit 34 of the second wiring board 42PCB acquires the operation information generated and supplied by the drive control unit 22 in step S203 from the main body unit 10B via the first connection unit 41CN.

[0106] (S205) Next, the communication control unit 34 acquires the position information acquired by the position information acquisition unit 36 and the information indicating the accuracy thereof from the position information acquisition unit 36. The position information may be corrected based on data detected by a speed sensor or the like provided in the rebar tying machine 10. Further, the position information may include altitude information acquired by the position information acquisition unit 36.

[0108] (S206) Next, the timestamp unit 30T acquires time information and adds this to the operation information. The predetermined time may be the time when the rebar tying machine 10 executes tying or a time equivalent thereto. The timestamp unit 30T may generate time information based on information acquired from a clock or the like (not shown) provided in the second wiring board 42PCB when operation information is supplied to the second wiring board 42PCB from the main body unit 10B, for example, and add this to the operation information. [[ID=3;9]]

[0109] (S207) Next, the communication control unit 34 stores the operation information in the operation information storage unit 30M. The signal control unit 34 stores information in the operation information storage unit 30M that is temporarily stored in case of communication failure. If operational information is already stored, it will be saved separately as new operational information. do.

[0110] The operation information storage unit 30M stores operation information in accordance with the control by the communication control unit 34. Specifically, the operation information storage unit 30M already stores temporary operations in case of communication failure. If motion information exists, the motion information storage unit 30M adds new motion information to the existing motion information. And remember it.

[0111] (S208) The communication control unit 34 reads the operation information stored in the operation information storage unit 30M and transmits it. The communication control unit 34 generates data. If communication fails, the operation information storage unit 30M stores the data. If there is operational information stored temporarily, it is read and the transmission data is generated. On the other hand, the communication control unit 34 stores only the operation information corresponding to one bundling operation in the operation information storage unit 30M. If so, this data is read and used to generate the transmission data.

[0112] Figure 10 is a schematic diagram showing an example of the transmission data structure generated by the communication control unit 34. The upper part of Figure 10 shows the data structure of operation information D1 corresponding to one bundling operation. The lower part of Figure 10 shows the operation information D2 corresponding to multiple binding operations. Operation information D Both 1 and D2 may include predetermined header information (an example of "meta information"). In the example shown in the diagram, TCP headers and HTTP headers are shown as header information. The TCP and HTTP headers are used between the rebar tying machine 10 and the management server 50. This is an example of header information that conforms to a predetermined communication protocol between the parties, such as the TCP header or HTTP header. The header information may include content appropriate to the communication protocol, not just the P header. Operational information D1 and D2 are both numerical values ​​that indicate the number of bundles included in the operation information, the number of data items. It may include. The operation information D1 corresponding to the number of bundles in one instance may be, for example, "1" as the number of data items. This includes the operation information D2 corresponding to the number of bundles, for example, as the number of data items. Includes a number indicating the number of times.

[0113] (S209) Next, the communication control unit 34 supplies the generated transmission data to the wireless communication device 32.

[0114] (S210) Next, the wireless communication device 32 receives the operational information supplied from the communication control unit 34 and transmits it to a predetermined communication network. Send to management server 50 via network.

[0115] (S211) The management server 50 acquires operational information from the rebar tying machine 10 and stores it. Specifically For example, the transmitting / receiving unit 521 of the management server 50 communicates with a rebar tying machine via the communication network. Upon receiving operational information from 10, the DB management unit 522 stores the operational information in a designated DB. Example For example, the DB management unit 522 stores information regarding the number of bundles included in the operation information in the operation information DB 51. It is stored in 4, and the location information and time information included in the operation information are stored in the location information DB513. You may put it in.

[0116] (S212) Next, the control unit 52 of the management server 50 operates based on the operation information obtained from the rebar tying machine 10. Then, various judgment processes are performed. Furthermore, the control unit 52 takes operation information from the rebar tying machine 10. If successful, information indicating that the operation information transmission was successful is sent to the rebar tying machine 10.

[0117] For example, if the operation information includes the position information of the rebar tying machine 10, the control unit 52 will... It may be determined whether or not it is included within the area associated with the location information. The information is stored in the tool information DB512 in association with the rebar tying machine 10, for example. It may also be information. And the control unit 52 determines if the rebar tying machine 10 is included within a predetermined area. If it is determined that it is outside the designated area, information will be provided to output the designated alert. The signal may be sent to the rebar tying machine 10.

[0118] Furthermore, the control unit 52 also includes, for example, the firmware and software version in the operating information. If information is included, refer to the version information etc. stored in the tool information DB512. The control unit 52 may determine whether or not firmware or software updates are necessary. The processing results may be transmitted to the rebar tying machine 10. Furthermore, if it is determined that an update is necessary, In addition, the control unit 52 transmits the firmware and software for updating to the rebar tying machine 10. That's good too.

[0119] (S213) Next, the wireless communication device 32 of the rebar tying machine 10 communicates with the management server via a predetermined communication network. The system receives predetermined information from the 50. The predetermined information to be received is, for example, the management system for operation information. It may also include information that the transmission to B50 was successful. In addition, the predetermined information to be received is A set alert (an alert indicating that the rebar tying machine 10 is outside the designated area), and Information regarding the version of your homeware or software (whether an update is needed, and the latest firmware) This may include (apparel, software, etc.).

[0120] (S214) Next, the communication control unit 34 receives information from the management server 50 indicating that the transmission of operation information was successful. If acquired, the process of deleting the operation information stored in the operation information storage unit 30M is executed. The operation information storage unit 30M deletes the operation information in accordance with the control of the communication control unit 34.

[0121] Furthermore, after executing step S209, the communication control unit 34 communicates with the management server 50. If it fails (for example, if there is no response from the management server 50 after a predetermined time has elapsed) (For example, if information indicating a failure to send operational information is received from the management server 50.) This does not delete the operation information. This means that the rebar tying machine 10 has performed the next tying. Then, an attempt will be made to send operational information to the management server 50 again.

[0122] (S215) Next, the communication control unit 34 receives information from the management server 50 that contains information about a predetermined alert. If included, the information of the alert is sent to the main unit 10B via the second connection unit 42CN and the first connection unit. It is supplied via section 41CN.

[0123] (S216) Next, the first wiring board 41PCB of the main body 10B has a predetermined control unit (first power control unit) 41PC and drive control unit 22, as well as any other control unit, are communication control unit 34 Based on the alert information supplied, an alert is issued. For example, an alert is issued. The force application is not particularly limited, but the rebar tying machine 10 emits an alarm sound from a predetermined speaker. The manner in which force is applied, and the display output (screen display or light emission) of a predetermined display unit provided by the rebar tying machine 10. It may also be in the form of (etc.). Furthermore, an application for managing the rebar tying machine 10 is A device such as a smartphone with the device installed (even if it is configured with any information processing device) If there is a user terminal (which may be a 60), an alert will be output via that terminal.
