The invention discloses an RFID (radio frequency identification devices)-based vehicle alarm system and a control method thereof. The system comprises a controller; the input end of the controller is connected with an RFID identifier, a vehicle state detection circuit, a vibrating sensor and a keying circuit; the output end of the controller is connected with a vehicle door control circuit, an oil-way control circuit, a voice module and a display module; the controller is used for controlling the working state of the RFID identifier in a manner that vehicle state information is acquired through the vehicle state detection circuit; password information is acquired from the RFID identifier by the controller, and an unlocking signal is sent to the vehicle door control circuit and the oil-way control circuit according to the password information. The RFID-based vehicle alarm system and the control method thereof disclosed by the invention have the significant effects that by detecting the working condition of a vehicle, the working state of the RFID identifier is automatically switched; the RFID-based vehicle alarm system has a password modification function and a password writing-in function, so that the vehicle alarm system is more intelligentized and humanized.
Description
technical field [0001] The invention relates to the field of automobile anti-theft technology, in particular to an RFID-based automobile anti-theft system. Background technique [0002] Traditional car anti-theft systems use wireless remote control. The wireless remote control has a large radiation to people and is easily disturbed, and the battery needs to be replaced; if the remote control key is lost or damaged, it has to be returned to the manufacturer for delivery or repair, which takes a long time and is cumbersome and inconvenient to use... [0003] RFID is a flexible application technology that is easy to control, simple and practical, and especially suitable for automatic control. It does not require contact or aiming; it can work freely in various harsh environments; it can perform a high degree of data integration; in addition, because this technology is difficult to be counterfeited and invaded, RFID has a very high security protection capability. [0004] Ther...
