Embodiment Construction

[0026] See figure 1 , a multi-sensor based intrusion detection method, in which motion sensor modules are installed at all detection positions in closed spaces that require intrusion detection, wherein the detection positions include doors, windows or other positions that require intrusion detection, and the motion sensor modules use Three-axis geomagnetic sensor, see Figure 4 , Figure 4 Among them, 10-1, 10-2, and 10-3 are all three-axis geomagnetic sensors. When the motion sensor modules 10-1, 10-2, and 10-3 are respectively set at the detection positions of the closed spaces that require intrusion detection, The calibration modules 70-1, 70-2, and 70-3 are used to calibrate each motion sensor respectively, and each calibration module simulates external disturbance factors to the motion sensor module and records the value of the motion sensor under the state of external disturbance factors as normal error, and then combine the normal error with the preset threshold to ob...

Abstract

The invention provides an intrusion detection method based on multiple sensors. The method can solve the problem that the detection result of an existing intrusion detection method is not accurate. Movement sensor modules used for periodically detecting movement state data of detection positions are arranged at all the detection positions of a closed space where intrusion detection needs to be conducted respectively, and if the movement state data of adjacent moments change and the change values of the movement state data exceed preset threshold values, it is judged that intrusion behaviors possibly happen to the detection positions; the judgment is verified through a video detector; the movement sensor modules are three-axis geomagnetic sensors. The invention further provides an intrusion detection system, the movement sensor modules and a video detection module are connected with an information storage module through data and signals, the information storage module is connected with a central calculation module through a bus, the movement sensor modules and a video detector are in communication through a communication module, and the central calculation module is in communication with a user terminal through the communication module.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to a multi-sensor based intrusion detection method and system. Background technique [0002] Intrusion detection is the discovery and detection of intrusion behavior. The intrusion detection system mainly collects and analyzes several key points in the computer network or computer system, and finds behaviors that violate the security policy in the network or system, such as access control, windows, etc. , safes, etc., once there is an illegal entry without the owner's permission, it is an intrusion detection. The Chinese invention patent application with the publication number CN102467800A discloses an intrusion detection and alarm system, which performs intrusion detection and alarm by means of face recognition, which has the problems of being unable to resist artificial cover and gesture dodge, so the effect of recognition and detection is not ideal; The Chinese in...
