<Procedure from registration to final closing>
FIG. 12 shows a processing procedure for flange tightening work. This procedure is an example of a flange tightening management program or tightening process.
In this processing procedure, after power-on and initial setting, wireless connection between the information acquisition unit 30 and the information terminal 50 is established (S301). After this wireless connection, it is determined whether the tightening management program is finished (S302). If the tightening management program ends (YES in S302), this processing procedure ends.

If this application is to be continued (NO in S302), the screen of the information presentation unit 28 is displayed (S303). Information such as application activation, registration, and tightening (FIGS. 15 and 16) and error information (FIG. 17) are displayed on this screen.
After displaying this screen, the process proceeds to the registration process (S304). This registration processing includes registration of preparation information before tightening, such as registration of the bolt member 10 , and the registered information is stored in the tightening information DB 94 .
In this registration process, it is determined whether resetting has been performed by operating the reset button on the display screen (S305). If it is a reset (YES in S305), the registration process is interrupted and the display returns to the screen (S303).

If not reset (NO in S305), the registration process (S304) is continued, and if the registration process is completed, the final tightening process of the bolt member 10 is performed (S306).
In this final closing, it is determined whether the processing has been reset by operating the reset button on the display screen (S307). If it is a reset (YES in S307), the registration process is interrupted and the display returns to the screen (S303).
If it is not reset (NO in S307), the final tightening (S306) is continued, and when the final tightening is completed, this process ends.

<Information Registration of Bolt Member 10>
FIG. 13 shows a processing sequence for information registration of the bolt member 10. As shown in FIG. Prior to this registration process, the information terminal 50 is wirelessly connected to the information acquisition unit 30 (S401). After establishing the wireless connection, the information terminal 50 instructs the information acquisition unit 30 to acquire information (S402). The information acquisition unit 30 having received this instruction acquires information from the information tag 12 (FIG. 1) of the bolt member 10 and notifies the information terminal 50 (S403).
The information terminal 50 registers the information acquired from the information tag 12 (S404). During this registration, it is determined whether the registration of information has been completed for all of the bolt members 10 to be registered on the flange 4 (S405).
If information registration has not been completed for all the bolt members 10 on the flange 4 (NO in S405), the process returns to S402 to continue information acquisition and notification (S403) and registration of the information (S404).
After this process, if registration of information has been completed for all the bolt members 10 to be registered on the flange 4 (YES in S405), the registration process is completed (S406).

<Final tightening of the bolt member 10>
FIG. 14 shows the final tightening processing sequence after the information registration of the bolt member 10 (FIG. 13). Prior to this final closing process, the information terminal 50 is wirelessly connected to the information acquisition unit 30 (S501). After establishing the wireless connection, the information terminal 50 instructs the information acquisition unit 30 to acquire information (S502). The information acquisition unit 30 having received this instruction acquires information from the information tag 12 and notifies the information terminal 50 (S503).
The information terminal 50 determines whether the information obtained from the information tag 12 is correct (S504). That is, in S504, when the operator installs the information acquisition unit 30 on the bolt member 10 to be subject to final tightening, the information obtained from the bolt member 10 is matched with the information on the bolt member 10 to be tightened. to determine if the

If the acquired information from the information acquisition unit 30 is correct (YES in S504), correct display is performed (S505), and if the obtained information is incorrect (NO in S504), incorrect display is performed (S506). . As a result, the operator is prompted to move the information acquisition unit 30 and the tightening tool 14 to appropriate positions based on the displayed content.
When this inappropriate display is issued, the process returns to S502, an information acquisition instruction is issued from the information terminal 50 (S502), and the information acquisition unit 30 acquires information again and notifies it (S503).

Then, if a proper display is obtained (S505), the information terminal 50 instructs the tightening tool 14 to permit final tightening (S507). Upon receipt of this final tightening permission, the trigger switch 88 of the tightening tool 14 can be pressed. As a result, final tightening is performed by the tightening tool 14 (S508), and a final tightening notification is issued from the tightening tool 14 (S509).
The information terminal 50 receives the final tightening notification from the tightening tool 14, and determines whether the final tightening has been completed for all the bolt members 10 to be registered on the flange 4 (S510).
If the final tightening of all the bolt members 10 on the flange 4 has not been completed (NO in S510), the process returns to S502 to continue the final tightening process of S502 to S510.
After this process, if final tightening has been completed for all bolt members 10 to be registered on the flange 4 (YES in S510), final tightening is completed (S511).
