Title:
DETECTION DEVICE AND DETECTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/111926
Kind Code:
A1
Abstract:
A detection device distinguishes at least two independent detectable blocks in a detection area. When an object enters the detection area and reflects detection medium sent by a signal emission source (1), a receiving element (2) receives the reflected detection medium and feeds the received signal back to an analysis and control circuit (4). The analysis and control circuit (4) identifies and processes signal characteristics and reflection orientation of the received signal, and then outputs the received signal through an output interface circuit. As the detection device can accurately identify the signal characteristics, and can analyze and judge multiple messages such as size, direction/speed/angle of motion and the like of the object entering the detection area, the detection device can be used for intrusion detection to avoid false alarm, and can also be used in various fields such as production process supervision/quality monitoring and the like.
