Signal comparison control means, and anti-theft alarm means as well as the intangible electric fence consisting of it

摘要

signal comparison control means, as the input signal meets the process requirements of the comparison module, a preprocessing module that is capable of pre-processing the input signal (1), and parameters of a preset reference signal before compares the output signal of the processing module (1), and comparison module that outputs a signal comparison result to the determining module (3) (2), a trigger condition is set in advance, outputs the comparison result of the signal comparison module trigger condition When satisfy, and an electric signal or the comparison result decision module that triggers output data (3). Further discloses an anti-theft alarm means as well as the intangible electric fence consisting of the signal comparison control means. The comparison signal control means, depending on the actual application environment, to reduce false alarms, it is possible to lower the false alarm rate.
