Radio frequency anti-theft equipment

Abstract

A radiofrequency theft protection device is provided, which comprises a central control processor 1, a data memory unit 2 and a theft protection execution circuit 3. Wherein, the central control processor 1 communicates with the data memory unit 2; the output end of the central control processor 1 is connected to the input end of the theft protection execution circuit 3. Besides, the invention also comprises a RFID radiofrequency receiver and a transmitting circuit 4. The output ends of the RFID radiofrequency receiver and the transmitting circuit 4 are connected to and communicate with a RFID card 9. With the wireless connection and communication between the RFID radiofrequency receivers, the transmitting circuit and the RFID card as well as the measures for preventing the signal from being intercepted and encrypted by air, the invention, which ensures excellent confidentiality and better theft prevention performance, is able to start up car or motorcycle without key. Therefore, the invention has the advantages of convenient application, intelligent operation and excellent energy saving.

Description

1. Technical field: [0001] The invention relates to a radio frequency anti-theft device. 2. Background technology: [0002] At present, the commonly used anti-theft device consists of a host and a remote controller. The host is installed on a car or motorcycle. The remote controller is carried by the owner to control the host on the vehicle. Alarm circuits and flameout controllers for automobiles or motorcycles, etc. The car owner can use the remote control to send a signal to the host to set the car to enter the alert state or to disarm the alert state, but the car and motorcycle need to be started, and the electric door lock must be opened by the key to open the electric door. The main disadvantages of this kind of anti-theft device are as follows: 1) When the remote controller transmits signals to the host, the signal coverage is large, and it is easy to be intercepted and decoded in the air, which greatly reduces the anti-theft security; 2) The anti-theft execution circ...

AI Technical Summary

Problems solved by technology

The car owner can use the remote control to send a signal to the host to set the car to enter the alert state or release the alert state, but the car and motorcycle need to be started, and the electric door lock must be opened by the key to open the electric door

The main disadvantages of this kind of anti-theft device are as follows: 1) When the remote controller transmits signals to the host, the signal coverage is large, and it is easy to be intercepted and decoded in the air, which greatly reduces the anti-theft security; 2) The anti-theft execution circuit is relatively simple, and it cannot be effective when entering the alert state Lock the car or motorcycle; 3) The remote control must cooperate with the key to start, which brings inconvenience in use
