Automobile anti-theft system

Abstract

The invention provides an automobile anti-theft system, consisting of an STM32F103VET6 microprocessor, an XN934 GPS receiver, a LORA transmission module, a pyroelectric infrared sensor, an ultrasonicsensor, an ADXL345 tilt acceleration sensor, a relay circuit, a voice module and a voltage stabilization power supply. The main functions of the system are: 1) many kinds of sensors are used to monitor the status of the vehicle in real time and transmit the information to the STM32F103VET6 microprocessor. The microprocessor judges whether the vehicle has illegal intrusion or not according to thesedata, and starts the voice alarm as soon as there is an abnormality, cuts off the vehicle power supply and notifies the vehicle owner; 2) The XN934 GPS receiver is placed outside the vehicle window to help obtain the position information of the vehicle accurately; 3) the LORA module is used to realize the long-distance wireless communication to inform the vehicle owner of the real-time status information and position information of the vehicle, so that the vehicle owner can realize the remote real-time grasp of the status of the vehicle.

Description

technical field [0001] The invention relates to the application field of an embedded single-chip microcomputer, combines sensing technology and Internet of Things technology, and specifically relates to an automobile anti-theft system. Background technique [0002] Along with the development of national economy, the use of automobile is popularized rapidly, but at the same time the incident of vehicle theft is more and more frequent. Therefore, people have put forward higher requirements for the anti-theft performance of automobiles. [0003] At present, the anti-theft devices of automobiles are mainly divided into three categories: mechanical anti-theft devices, electronic anti-theft devices, and networked anti-theft alarm systems. The common mechanical anti-theft device is the original lockset of the vehicle (such as car door lock, ignition switch lock), mainly to prevent the use of the engine, but it cannot realize the alarm function. The electronic anti-theft device ma...

AI Technical Summary

Problems solved by technology

The common mechanical anti-theft device is the original lock of the vehicle (such as door lock, ignition switch lock), mainly to prevent the use of the engine, but it cannot realize the alarm function

The electronic anti-theft device mainly controls the start or stop to realize anti-theft, and also has an alarm function, but it cannot realize remote alarm

Networked anti-theft alarm systems, currently mainly include GPS / GPRS system and GPS / GSM system, which can not only prevent theft, but also remote tracking, but the cost is high, and it cannot fully reflect the status information of the vehicle
