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.

Claims

1. A patrol method of a patrol system, when a patrolman with a receiving and sending communication device arrives at a designated patrol location, and the receiving and sending communication device senses signal element disposed at the patrol location, the receiving and sending communication device will give feedback to a computer, and then the computer will determine next patrol location to be patrolled after receiving the feedback from the receiving and sending communication device, and will transmit data of the next patrol location to the receiving and sending communication device;

the patrol method randomly determines the next location to be patrolled based on the following principles;

A. the next location to be patrolled should be neighboring to the patrol location which is being patrolled;

B. the next location to be patrolled is allowed to be the location which has been patrolled, and the probability of patrolling the patrolled location is comparatively low and the probability of patrolling the non-patrolled locations is relatively high;

C. the probabilities of patrolling are also different from specific patrolled location to specific patrolled location, the longer the time has passed since a location was patrolled, the more likely this location is to be patrolled, and vice versa, the shorter the time has passed since a location was patrolled, the less likely this location is to be patrolled;

D. the computer is able to predetermine important patrol locations such that the important patrol locations are set to have a higher probability of patrolling than general patrol locations.
