Furnishing theft-proof detection device and detecting method thereof

Abstract

The invention provides a furnishing theft-proof detection device and a detecting method thereof. In the furnishing theft-proof detection device, a local furnishing surface or an object surface adhered on the furnishing surface is taken as a detecting area, the characteristic that furnishings are usually placed in fixed points and fixed places is utilized, and an alarm signal is sent out when displacement of the furnishings is detected, so that interference of environmental factors is greatly reduced, the theft-proof detecting sensitivity of the furnishings is improved, the structure is simple, and the cost is low; and the device has excellent industrial production and market popularization prospects. The detecting method for the furnishing theft-proof detection device uses grey values of pixels in an imaging image in the detecting area as a detection judgment basis, has higher space sensitivity and time sensitivity and a simple algorithm, can be easily realized through a programming technology by common programming technicians without a special software technical platform, and has a wide application range.

Description

technical field [0001] The invention belongs to the fields of anti-theft technology for furnishings and electronic products, and in particular relates to an anti-theft device for furnishings and a detection method for the device. Background technique [0002] Furnishings refer to items that are used to beautify or enhance the visual effect of the environment and have ornamental value or cultural significance. Usually, many valuable furnishings are displayed in museums and exhibition halls for people to visit, so the anti-theft detection facilities for furnishings are indispensable and important security facilities in museums and exhibition halls. The current anti-theft detection of furnishings mainly adopts anti-theft detection methods such as voice control, infrared induction, microwave, and piezoelectric induction. Among them, voice control anti-theft mainly relies on detecting characteristic sounds such as knocking anti-theft locks and anti-theft glass breaking; infrared...

AI Technical Summary

Problems solved by technology

These anti-theft detection methods for furnishings are more or less interfered by environmental factors. For example, voice-activated anti-theft is easy to misjudge the unique sound in the environment as a characteristic sound and alarm. Infrared induction anti-theft and microwave anti-theft cannot be used during exhibition hours. Inductive anti-theft, the piezoelectric induction device has a short service life and is easily deceived by equal-pressure heavy objects. These factors have led to the embarrassing problems of the existing anti-theft detection methods for furnishings, such as insufficient environmental adaptability, limited detection sensitivity, and frequent replacement. This situation also makes the detection technology of high-sensitivity methods for exhibits has always been a key topic of academic research.
