Sensing system and biological sensing alarm method of a biological sensing alarm device

Abstract

The invention discloses an induction system of a biological induction alarm device and a biological induction alarm method. The system comprises an induction wire which is arranged in an induced electric field and used for inducing the intensity of the induced electric field. The wire converts the obtained intensity information of the induced electric field into a voltage signal. The system further comprises a filter used for filtering the voltage signal, a control module used for controlling the intensity of the induced electric field and judging whether there is a need to raise the alarm, and an alarm system used for sending out an alarm signal. The alarm device is controlled by the control module flexibly and automatically, so that the induction system can adapt to the interference of the external environment. Meanwhile, the risk of misjudgment caused by accidental touch of small animals is reduced, and the reliability of equipment is improved.

Description

technical field [0001] The invention relates to the field of electronic anti-theft, in particular to an induction system of a biological induction alarm device. Background technique [0002] Compared with other anti-theft sensing devices, biological sensing alarm devices are relatively rare in the current domestic and foreign markets. Compared with other anti-theft devices, such as infrared sensing devices, they have the advantages of high reliability and good safety, as shown in Chinese patent CN01107018 An electronic anti-theft fence and its manufacturing method are described. The electronic anti-theft fence disclosed in this patent is a bio-sensing electronic anti-theft fence, but the bio-sensing device is easily disturbed by the external environment, such as the interference of rainy weather. The alarm is triggered by the false touch of small animals such as birds and mice, which is difficult to meet the diverse needs of use. [0003] Due to the above reasons, the prese...
