The transmitting / receiving unit 37 for transmitting / receiving data to / from the mobile terminal device 24, signals received by the transmitting / receiving unit 37, or signals from the CPU CPU 38 and CPU 32 for driving the inspection work manual program 42 and the work procedure program 43 stored in the ROM 39 based on signals such as an interface I / F for outputting hand movement signals and tool information from the portable terminal. Are composed roughly of a RAM 41 for storing the result of the calculation, a ROM 39 for storing an inspection work manual program 42 and a work procedure program 43.

  In the inspection work system having such a structure, first, the work procedure program 43 is loaded into the CPU 38 of the server 26 so that it can be sequentially processed. On the other hand, the fieldman 25 carries the portable terminal device 24 and has a glove with a sensor. It is assumed that the inspection work can be performed with 21 performed.

In this state, it is detected by the IC tag information reading means 23 attached to the glove 21 with the sensor that the fieldman 25 goes to a predetermined inspection place and selects an appropriate tool. First, it is verified whether or not the correct tool is selected.
The selected tool is then used to determine whether the glove is performing a predetermined action, such as whether the tool is a screwdriver or a spanner, tightening, loosening, grasping if it is pliers, or twisting. Analysis can be performed with the detection states of the acceleration / position information sensors 22a, 22b, 22c, 22d, and 22e attached to five fingers.

  FIG. 4 shows a state where the driver 27 is grasped and a predetermined screw is loosened. As shown in FIG. 4A, when the driver 27 is first grasped, the sensors 22a, 22b, 22c, 22d, 22e, As the position of 22f moves in a concentrated manner toward the handle portion of the driver 27, the detection signals of the sensors 22a, 22b, 22c, 22d, 22e, and 22f are analyzed to determine whether or not the driver 27 is currently grasped by grasping this state. It is solved by doing. Next, as shown in FIG. 4B, when the screwdriver 27 is used to loosen the screw, the sensors 22a, 22b, 22c, 22d, and 22e that are concentrated on the handle portion of the driver 27 are used. , 22f move all the way to the left and analyze the detection signals from the sensors 22a, 22b, 22c, 22d and 22e for subtle deviations in the distance between the fingers 22a, 22b, 22c, 22d and 22e. By doing so, it can be determined that the driver 27 has moved in the loosening direction while holding the handle.

  As described above, the detection signals of the sensors 22a, 22b, 22c, 22d, 22e, and 22f are analyzed based on whether a predetermined appropriate tool is used or whether an appropriate work is performed using the tool. It can be easily grasped.

  Furthermore, the analysis of the detection signals by the sensors 22a, 22b, 22c, 22d, 22e, and 22f is preliminarily determined in the work procedure, and the major premise is to specifically execute what is described in the manual. So, in this inspection work, it is possible to determine even the very details that need to be moved in which direction using which tool.

  And there exists a certain operation | movement pattern about the holding state usage of the tool to be used among this series of work processes. By accumulating this operation pattern in the database, it is possible to grasp in advance how to use a series of tools in a predetermined inspection work, so an alarm when a different tool is actually selected, By generating an alarm when the tool is not used properly, it is possible to control, for example, too loose or too tight.

  In the inspection work, an inspection work system is provided in which it is determined whether or not the inspection is appropriate by grasping the handling of the tool from the detection state of the sensor.
