Abstract
A management system includes a monitoring device and at least one detection device. The monitoring device projects detection light for detecting a monitoring target, and identifies the monitoring target based on a detection pattern of reflected light of the detection light. The detection device is installed on the monitoring target. The detection device receives the detection light projected by the monitoring device, and reflects the detection light at a timing set to the detection device in a predetermined period starting from a timing at which the detection light is received.
