Abstract

The invention discloses a wireless transmitting intelligent anti-theft system based on a band-pass filtering amplifying circuit. The intelligent anti-theft system mainly comprises a central processing unit, a first wireless signal transmission module, a second wireless signal transmission module, a PC machine, an image collector, a vibration sensor, a data memory, a sound collector, a power supply, an alarm, and an image signal automatic gain circuit, wherein the vibration sensor, the data memory, the sound collector, the power supply, and the alarm are all connected to the central processing unit, and the image signal automatic gain circuit is serially connected between the image collector and the central processing unit. The intelligent anti-theft system is characterized in that a band-pass filtering amplifying circuit is also serially connected between the sound collector and the central processing unit. The intelligent anti-theft system of the invention can accurately record images and sound in a stolen process, and accurately and effectively transmits stolen information to users or the public security officers in the first time so as to prevent the user property against being lost.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an intelligent anti-theft system based on wireless transmission of a band-pass filter amplifier circuit. Background technique [0002] Existing safes are limited to audible and visual alarms, and the surrounding environment is not well monitored. When a safe is stolen, the process of the theft cannot be recorded, and the stolen information cannot be obtained at the first time, which affects the safety of the safe. Recover and solve the case. The alarm function of the current safe is limited to the sound and light alarm, and the alarm information for the user is seldom. The user cannot understand the situation on the safe site well. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the anti-theft system of the safe in the prior art cannot record the stolen process, and the present invention provides an intelligen...
