Abstract

The invention discloses a wireless transmission intelligent antitheft system based on a signal filtering amplification circuit. The system is mainly formed by a central processor, a first wireless signal transmission module, a second wireless signal transmission module, a PC, an image collector, a vibration sensor, a data storage device, a sound collector, a power supply, an alarm and an image signal automatic gain circuit, wherein the vibration sensor, the data storage device, the sound collector, the power supply and the alarm are connected with the central processor; and the image signal automatic gain circuit is serially connected between the image collector and the central processor. The antitheft system is characterized in that a signal filtering amplification circuit is also serially connected between the vibration sensor and the central processor. The antitheft system is capable of precisely recording images and sound during the stealing process, and precisely and effectively transmitting the stolen information to a user or the police immediately so as to ensure that the user will not lose property.

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 signal filtering and amplifying 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 process of the theft, and the present invention provides an...
