Receiving means (not shown). That is, the hands-free tags 4a, 4b, and 4c function as transmission means, and the buttons function as intention confirmation means.

  Although not shown in FIG. 1, the tag authenticating device 3 is based on the authentication request received by the receiving means, a judging means for judging whether or not to execute the control operation of the important equipment 1; An output means is provided for outputting a signal for controlling the important equipment 1 when the judgment permission is output by the judgment means. Note that the determination means and output means of the tag authentication device 3 are configured by software.

The equipment control system according to the first embodiment is configured as described above, and the operation thereof will be described next.
FIG. 2 is a flowchart showing the operation of the equipment control system according to the first embodiment. In FIG. 2, when starting control operation of the important equipment 1, first, button operation of the hands-free tags 4a, 4b, 4c is executed in step S1, and the process proceeds to step S2.

  In step S2, the tag authentication device 3 determines whether tag information has been received from the hands-free tags 4a, 4b, 4c. If tag information has been received, the process proceeds to step S3. If tag information has not been received, step S3 is performed. It progresses to S6 and it is judged whether predetermined time passed. In addition, when predetermined time does not pass by step S6, it returns to step S1, and when predetermined time passes, control operation of the important installation 1 is complete | finished.

  In step S3, an operator who has the authority to judge whether to execute the control operation of the important facility 1 in which the tag information from the hands-free tags 4a, 4b, 4c received by the tag authentication device 3 is registered in advance is possessed. It is determined whether or not the tag information is from the hands-free tags 4a, 4b, and 4c.
