Abstract

The invention relates to a vehicle anti-theft tracking circuit based on a LoRa (long range) radio frequency technology. A power supply part of the vehicle anti-theft tracking circuit is divided into a high voltage transformation circuit and a low voltage transformation circuit, and after a vibration switch detects vibration, the low voltage transformation circuit is switched on to provide low-voltage power supply for a system. STM8L151C8 microcontroller is taken as the core to perform information interaction with a GPS / beidou double-star positioning circuit through a UART serial port and communicates with an SX1278 radio frequency circuit through an SPI, status information of the system is sent to a LoRa base station, and long-distance transmission with low power consumption is realized. An alarm interface is used for accessing a vehicle control terminal, and the terminal initiatively uploads alarm data once a vehicle is stolen. The latest vehicle position and alarm lamp status data are sent with a LoRa wireless transmission technology, so that the effects of real-time vehicle tracking, theft alarm and the like are realized, and vehicle losing is prevented.

Description

technical field [0001] The invention relates to a vehicle anti-theft tracking system based on a new type of long-range LoRa (Long Range) radio frequency technology, specifically a vehicle anti-theft tracking alarm circuit that can realize GPS / Beidou dual-star positioning, remote alarm data upload, low power consumption and low cost . Background technique [0002] With the increase of vehicles, automobiles and electric vehicles have been frequently stolen in recent years, and vehicle safety has become a social problem that needs to be solved urgently. The existing vehicle anti-theft technology can no longer meet the needs of users. As a mobile anti-theft system, the vehicle anti-theft tracking system is widely used in commercial transportation, logistics distribution, enterprise fleets, car rental, intelligent transportation, shipping, emergency command, emergency rescue, military and police safety supervision and other fields. Most of the existing anti-theft tracking produc...
