FIG. 1 shows an example of a fastening management processing process according to the first embodiment. The process shown in FIG. 1 is an example of the conclusion management method and the conclusion management program of the present disclosure, and the technique of the present disclosure is not limited to such a configuration.

As shown in FIG. 1, for example, the fastening management process includes a signal receiving step (S101), a worker 10 position information and movement information collecting step (S102), and a worker 10 allocation information and process information reading step (S10). S103), authentication processing process of worker 10 (S104), notification process of instruction information to worker 10 (S105), acquisition process of work report information (S106), evaluation process of work state (S107), registration of work database. The step (S108) is included. This conclusion management process is executed by, for example, the conclusion management system 2 shown in FIG.

Signal receiving process (S101): In the conclusion management system 2, for example, the management server 4 having the function of arranging the worker 10 and the function of monitoring the working state receives a signal indicating the position information of the worker 10.

This signal is transmitted from a transmitter 11 possessed by the worker 10, or installed in a device possessed or used by the worker 10 for movement, for example. The transmitter 11 is an example of a device that continuously transmits radio waves having a predetermined frequency at a set timing, for example.

In the conclusion management system 2, all the workers 10 assigned to the conclusion processing of the plant equipment are made to carry a transmitter 11 for transmitting an identifiable signal, so that the position of each worker 10 is grasped.

Step of collecting location information and movement information of worker 10 (S102): The management server 4 analyzes signals received after or during movement to, for example, each work location, and based on the identification of the signals, the management server 4 of the worker 10. Acquire location information and movement information.

The management server 4 grasps the position of the worker 10 by using, for example, map information of the plant equipment, setting in the plant equipment, or sitting table information such as latitude and longitude. Further, the management server 4 grasps the movement state and the movement information of the worker 10 by grasping the movement of the worker 10 by the two or more signals received after the lapse of time.

This movement information indicates the transition of the position at the transmission timing of the signal by the transmitter 11, and does not necessarily indicate the route to which the worker 10 has moved. In addition, the management server 4 may acquire time information when a signal is received by a timer or the like.

Step of reading allocation information and process information of worker 10 (S103): The management server 4 reads allocation information and process information registered in the database (DB) 6 (FIG. 2).

The allocation information of the worker 10 is an example of information in which the person in charge of the fastening process is assigned to the work location including the flange fastening portion of the plant equipment.

Notify instruction information including work instructions such as.

This instruction information is transmitted, for example, to the terminal device 12 possessed by the worker 10 by e-mail, a dedicated program, or other means. The worker 10 refers to the notified instruction information, or sets a program of this instruction information in the fastening tool and performs the fastening process.

Work report information acquisition process (S106): The management server 4 receives the work report information of the fastening process from the work location set in the plant equipment.

This work report information is generated, for example, at the completion of work or at a predetermined timing for one or more fastening parts in the work place, and is notified to the management server 4 side.

The work report information is work state information including, for example, the bolt and nut fastening state, the working time information, the progress status, etc., and is based on the work created by the worker 10 or the work result collected by the fastening tool, the controller, or the like. It is created based on the result of the check of the fastening state performed by the terminal device 12 automatically created by the terminal device 12 and other work supervision (not shown).

Work state evaluation process (S107): The management server 4 evaluates the progress state of the conclusion process by comparing the acquired work report information with the process information.

In this evaluation process, for example, whether or not the fastening process is completed according to the elapsed work time set in the process information, the axial force value specified for the bolt and nut fastening state, and the surface pressure on the gasket intervening between the flanges. It is evaluated whether the value etc. meets the specified conditions.

Work database registration process (S108): The management server 4 registers the evaluation result of the work status in the work status database 18 and the like.
