Embodiment 1

[0038] This embodiment specifically describes the technical principle of the composite detection alarm in the technical solution of the present invention.

[0039] Such as figure 1 As shown, 1 indicates that the area is located in the protected area, and personnel in the restricted area are strictly restricted, that is, personnel are not allowed to enter the area. 2-5 respectively indicate image motion detection intrusion detectors and infrared, microwave, ultrasonic and other non-image motion detections Intrusion detectors, after connecting image motion detection intrusion detectors and infrared, microwave, ultrasonic and other non-image motion detection intrusion detectors to the alarm input interface on the composite motion detection intrusion detector 6, the composite motion detection The intrusion detector performs internal calculations on the detection results of image motion detection intrusion detectors and infrared, microwave, ultrasonic and other non-image motion detecti...

Embodiment 2

[0044] This embodiment specifically describes that the technical solution of the present invention uses several commonly used composite detection alarms to perform the detection work of the prohibited area.

[0045] Such as figure 2 As shown, this embodiment is based on the application of the principle of the technical solution of the foregoing embodiment 1, using a compound motion detection built with pure logic levels such as discrete components, integrated circuits, etc., with a logic and arithmetic function Functional intrusion detectors to perform detection work in prohibited areas. As shown in the figure, DI1-DI8 are the interface for connecting sensors, which can be connected to various types of motion detection sensors as mentioned above. The internal two-level "logic AND" arithmetic unit composed of "AND" gates, with 8 front-level And gate, if there is an AND gate output is "0", the output of the subsequent AND gate is "0", that is, there is no alarm output at the DO te...

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 field of detection technology, in particular to a detection alarm method and system that can greatly reduce the false alarm rate of movement detection. Background technique [0002] With the rapid development 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 being involved in detection in the area. Most of them use Outdoor passive infrared intrusion detectors, outdoor microwave intrusion detectors, outdoor passive infrared-microwave intrusion detectors, outdoor ultrasonic intrusion detectors, and camera-collecting images for photoelectric comparison-based motion detection methods. These methods are in In practical applications, there is a certain false alarm rate, especially for non-image detection methods. After a false alarm occurs, it is ...
