Abstract: A patrol system comprises: a computer, a receiving and sending communication device, and a plurality of signal elements. The computer and the receiving and sending communication device are wirelessly connected to each other. The receiving and sending communication device serves to sense the signal elements. The signal elements are disposed at designated patrol locations. When a patrolman with a receiving and sending communication device arrives at a designated patrol location and gives feedback to the computer, the computer will determine next patrol location to be patrolled and inform the patrolman. And thus the patrol route of each patrolman is determined randomly by the computer, so that the thief doesn't know the patrol route. Further, even the patrolman doesn't know the next patrol location to be patrolled, thus preventing the patrolman from colluding with the thief and betraying the patrol route.
