Patrol system

The invention provides a patrol system, which relates to the field of monitoring and comprises a patrol sensing device arranged at a check point and a patrol device carried by patrol personnel. The patrol sensing device comprises an illuminating lamp, an illuminating driver and a position compiler, and the output end of the position compiler provides driving voltage with check point coding information for the illuminating driver; the output end of theilluminating driver is connected with the illuminating lamp, so that theilluminatinglamp sends out a light signal carrying check point coding information; the patroldevice is used for receiving the optical signal and recording checkpoint coding information corresponding to the optical signal. The patrol device in the patrol system can automatically sensethe patrol sensing device arranged at the check point, so that the occurrence rate of mistaken absenteeism and mistaken late recording is effectively reduced. 本发明提供一种巡更系统，涉及监控领域，包括设置在检查点的巡检感应装置和巡检人员所携带的巡检器，巡检感应装置包
