Vehicle anti-theft system based on band-pass filter

Abstract

The invention discloses a vehicle anti-theft system based on a band-pass filter. The vehicle anti-theft system based on the band-pass filter includes a data detection and control terminal and a mobileterminal which is connected with the data detection and control terminal. The data detection and control terminal includes a processor module, a monitoring module, a signal processing module, a alarmmodule, a communication module, a execution module and a power supply module. The monitoring module is connected with the processor module through the signal processing module. The alarm module, thecommunication module and the execution module are correspondingly connected with the processor module. The power supply module is connected with the processor module, the monitoring module, the signalprocessing module, the alarm module, the communication module and the execution module to provide the electrical energy required. The signal processing module comprises an analog-to-digital conversion module, an amplifying circuit module and the band-pass filter. The vehicle anti-theft system based on the band-pass filter provides an amplifier circuit of a three stage magnifying structure, the three stage magnifying structure is designed, and the conversion rate of an amplifier is significantly increased. The vehicle anti-theft system based on the band-pass filter is worth popularizing.

Description

technical field [0001] The invention belongs to the field of intelligent vehicle monitoring, in particular to a motor vehicle anti-theft system based on a band-pass filter. Background technique [0002] With the improvement of living standards, owning a private car has become one of the signs that a family enters a fashionable and modern life. But along with the increase in the number of motor vehicles, thieves have also begun to set their sights on motor vehicles as high-end consumer goods. Although most of the current motor vehicles are equipped with original anti-theft devices, there are also various brands of motor vehicle additional anti-theft devices on the market, but these anti-theft devices are not only focused on passively handling the situation when encountering an alarm, but also for the judgment of the alarm. The reliability of the theft process has not been paid enough attention, resulting in misreporting and omissions from time to time, which has caused a lot...
