Abstract
The invention discloses an intra-area equipment spot inspection authenticity identification device which comprises a first infrared detection switch and a second infrared detection switch which are sequentially arranged from the inlet of the area to the inner portion of the area in a spaced mode, and a PLC control system electrically connected with the first infrared detection switch and the second infrared detection switch at the same time. The PLC control system can record and save the times when the first infrared detection switch and the second infrared detection switch are triggered. When the trigger time of the first infrared detection switch is earlier than the trigger time of the second infrared detection switch, the PLC control system judges that people are in the area entering state at the moment and uses the trigger time of the first infrared detection switch as the area entering time. When the trigger time of the second infrared detection switch is earlier than the trigger time of the first infrared detection switch, the PLC control system judges that people are in the area leaving state at the moment and uses the trigger time of the second infrared detection switch as the area leaving time. The device has the advantage that the intra-area equipment spot inspection authenticity can be accurately identified.
