The invention discloses an invasion object detection method and an invasion object detection device for perimeter security systems. The method includes the steps of sequencing links according to positions of the links; acquiring a signal strength indication sequence of each link; acquiring a fluctuation measurement indicator of each link according to a signal strength indication sequence of each link; sequencing the fluctuation measurement indicators according to sequencing results of the links, clustering the spatial sequencing results of the fluctuation measurement indicators according to preset clustering thresholds, and acquiring each category after clustering; determining whether or not invasion objects exist in regions, in which the links corresponding to the categories are located,according to judgment parameters. The invasion object detection method and the invasion object detection device have the advantages that the fluctuation measurement indicators of the links are clustered spatially by considering the spatial relevance among the links, whether or not the corresponding links have invasion objects is determined according to the judgement parameters of the categories, interference of interfering substances on invasion object detection is effectively reduced, and the accuracy of invasion object detection is improved.
Description
technical field [0001] The present application relates to the technical field of signal processing, in particular to an intruder detection method and device applied to a perimeter security system. Background technique [0002] With the increasing awareness of the importance of security in all walks of life, perimeter security systems are usually installed around key control areas, such as airports, prisons, chemical plants, and important material storage areas, even in residences, office buildings, and schools. Perimeter security systems are often installed around conventional buildings and areas. The perimeter security system is used for real-time detection of the security area, and when illegal intrusion is detected, it can send out an alarm signal in time. As the first barrier against intrusion, vandalism and theft, the perimeter security system plays an important role in social security. [0003] At present, commonly used perimeter security systems usually include: vib...
