Abstract
The utility model provides an infrared ray theft-proof network with direction identifying function, comprising two assembled couples of infrared emitters/infrared receivers installed oppositely, and subsequent components. The theft-proof network is characterized in that said assembled couples of infrared emitters and infrared receivers adopt the structure of two-layer defensive interfaces arranged in parallel; driven by subsequent components, the infrared pulse radial between one of the assembled couples of infrared emitters/infrared receivers forms a layer of defensive interface, and the infrared pulse radial between the other assembled couples of infrared emitters/infrared receivers forms another layer of defensive interface. When an object passes through, the object interdicts the infrared pulse radials of different defensive interfaces in sequence so as to trigger two corresponding signals; the subsequent components compare the order of the two triggering signals and judge the direction of motion of the object when the object passes through the defensive interface so as to exactly predict invasion (entering from outside) and leaving (going out from inside).
