If it is determined in step S21 that the number of discriminating bodies 8 having the same attribute as that of the discriminating body 8 and having a radius of 2 m around the discriminating body 8 is not one, the process proceeds to step S22.

  In step S22, the detection device 7 determines whether or not the number of the identification bodies 8 existing in the range of the radius 2 m with the same attribute as the identification body 8 is two.

  When the number of discriminating bodies 8 existing in the range of radius 2m with the same attribute as the discriminating body 8 in the step S22 and within the radius of 2 m is two, the operations after step S15 are performed. If it is determined in step S22 that the number of discriminating bodies 8 having the same attribute as that of the discriminating body 8 and having the radius of 2 m around the discriminating body 8 is not two, the process proceeds to step S23.

If the number of discriminating bodies 8 having the same attribute as that of the discriminating body 8 and having a radius of 2 m within the radius of 2 m is not 3 or 4 in step S23, the operation is terminated.

  According to the third embodiment described above, the identification object 8 having the same attribute as the abnormality detection target 8 and the distance from the abnormality detection target 8 being shorter than the preset distance is used. Based on the number, the time interval at the time of detecting the user's abnormality corresponding to the identifier 8 to be detected is changed. For this reason, when a user having an attribute different from that of the user corresponding to the identification object 8 that is the target of abnormality detection is passed, the detection of the abnormality of the user corresponding to the identification object 8 that is the target of abnormality detection is delayed. Can be prevented.

  Further, when the number of the identification bodies 8 having the same attribute as that of the identification body 8 to be anomaly detected and the distance to the identification body 8 to be anomaly detection is shorter than the preset distance is equal to or more than the preset number. The safety confirmation system does not detect the abnormality of the user corresponding to the identifier 8 that is the target of abnormality detection. For this reason, in a situation where a plurality of users can mutually confirm safety, it is possible to reduce the calculation load in the safety confirmation system.
