Abstract

The invention relates to the detection technical field, in particular to a detection alarm method which can significantly reduce motion detection false alarm rate, and a system thereof. The method comprises the following steps: detecting a monitoring area with two or more different types of detectors; inputting the detection result of the different types of the detectors into a computation modulefor logical AND operation; and outputting an alarm signal if the result shows that the different types of the detectors are all triggered in the logical AND operation, otherwise, not outputting the alarm signal. By taking photoelectric motion detection, microwave field motion detection, infrared filed motion detection and ultrasonic wave field motion detection in a video as a complex alarm detection source, the method help effectively reduce the false alarm rate of a single physical detection mean, significantly utilize the advantage of various physical detection means such as integration composition, improve detection accuracy of the system on personnel moving targets in a prohibited involving area, and reduce invalid information output of false alarm.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection and alarm method and system that can greatly reduce the false alarm rate of mobile detection. Background technique [0002] With the take-off of information technology in the 21st century, intelligent security technology has entered a new field with the development of science and technology. At present, outdoor public security and industrial security personnel are prohibited from getting involved in the detection of the area, and most of them use Outdoor passive infrared intrusion detectors, outdoor microwave intrusion detectors, outdoor passive infrared-microwave intrusion detectors, outdoor ultrasonic intrusion detectors, and methods for collecting images by cameras and performing photoelectric comparison motion detection. In practical applications, there is a certain rate of false alarms, especially for non-image detection methods. After false alarms occur, it is...
