RFID (radio frequency identification) intelligent anti-theft system of electric motor car and control method thereof

Abstract

The invention relates to an intelligent anti-theft system of an electric motor car and a control method thereof, and the intelligent anti-theft system comprises an RFID (radio frequency identification) circuit, a central control unit and an automatic control lock module. The central control unit comprises a main control MCU (micro controller unit), an acousto-optic steering circuit, an oscillation alarm circuit, a loudspeaker circuit, an electronic switch and a state monitoring circuit. The RFID circuit collects ID (identification) card information and operating order of a user, the data are sent to the main control MCU for processing so as to form a control signal which is sent to a drive circuit for driving a motor; a lock mechanism is driven to push and pull a lock post to stretch out and draw back through a speed reduction gear box; and an expansion brake lock is locked. The system provided by the invention is high in integration degree, simple in operation and high in safety and reliability, solves the problems of complex operation and high possibility of damage of the existing mechanically electric door lock, as well as inconvenience in operation and high possibility of being blocked by mud of a mechanical expansion brake lock (or a head lock), lowers the cost of manufacturers, and integrates the RFID identity identification, electronic lock, electronic expansion brake lock (or head lock), anti-theft alarm and acousto-optic steering indication.

Description

technical field [0001] The present invention relates to an intelligent anti-theft system and control method for electric vehicles, in particular to an intelligent system that not only has the function of RFID identification, but also realizes automatic anti-theft in combination with a brake lock or a faucet lock mechanism. It is suitable for electric vehicles and other Similar to vehicle use. Background technique [0002] With the advantages of simplicity, lightness, low price, and environmental protection, electric vehicles are more and more widely used by people. However, with the increase in the number of electric vehicles, the safety and anti-theft of electric vehicles have also attracted more and more attention. At present, the common solution is to use a mechanical key switch to turn off the electric door lock, install a mechanical expansion gate lock or a mechanical faucet lock, and install a high-frequency long-distance remote control alarm, but the mechanical electr...

AI Technical Summary

Problems solved by technology

At present, the common solution is to use a mechanical key switch to turn off the electric door lock, install a mechanical expansion gate lock or a mechanical faucet lock, and install a high-frequency long-distance remote control alarm, but the mechanical electric door lock is easy to crack and the operation is cumbersome Due to the limitation of the installation position, the mechanical expansion brake lock or the mechanical faucet lock is inconvenient for the user to operate. If the user forgets to unlock the lock before riding, the motor will be easily damaged when starting the electric vehicle. Distance operation is easy to be stolen and copy the remote control code, thus losing the significance of anti-theft; Turning to independent components such as horns, this is not only inconvenient to install and use, but will inevitably increase the cost of the vehicle to a large extent, which is not conducive to the wider consumer groups of electric vehicles
