First install a passive wireless patrol point at the specified location, then set the location name, patrol personnel and patrol time via software. The patrol personnel hand-held the patrol equipment to the designated location to sense the inspection point according to the time requirement, and the patrol equipment automatically records the location name and arrival time. After the patrol is finished, the data is uploaded to the management center via USB. The inspection report is calculated on a daily,monthly and annual basis to provide a scientific and effective assessment basis for managers.
