Problems solved by technology

However, the current market is generally one-way, and the remote control transmits wireless signals to the base station installed on the car to realize the opening and closing of the car door. This one-way wireless transmission signal is easily received and deciphered by theft device, and the encryption performance is not high. It will create an opportunity for car thieves to easily steal the car; and the emission of the signal requires manual buttons and cannot be automatically sensed, so the operation is not convenient enough, especially when the car owner is carrying things in both hands and it is inconvenient to put them on the ground ( as rainy day)

Abstract

A dual-radio-frequency burglar alarm comprises a main control base station mounted inside an automobile and provided with a high-frequency receiving device, a first single-chip microcomputer processing center, a low-frequency emitting device and an executing device, and a key provided with a low-frequency receiving device, a second single-chip microcomputer processing center and a high-frequency emitting device corresponding to the main control base station. A bidirectional radio frequency induction recognition achieved by the main control base station and the key is achieved, automatic unlocking can be achieved by an automobile owner within the signal induction range without key triggering, automatic locking, window closing and flameout can be achieved beyond the induction range, and automatic alarm giving can be achieved when a door lock is opened and an automobile is started illegally without signal induction.

Description

technical field [0001] The invention relates to the field of automobile anti-theft, in particular to a double radio frequency anti-theft device. Background technique [0002] In order to prevent the car theft from happening, people usually install anti-theft devices on cars. However, the current market is generally one-way, and the remote control transmits wireless signals to the base station installed on the car to realize the opening and closing of the car door. This one-way wireless transmission signal is easily received and deciphered by theft device, and the encryption performance is not high. It will create an opportunity for car thieves to easily steal the car; and the emission of the signal requires manual buttons and cannot be automatically sensed, so the operation is not convenient enough, especially when the car owner is carrying things in both hands and it is inconvenient to put them on the ground ( such as a rainy day). Contents of the invention [0003] In ...
