Problems solved by technology

The communication between the proximity card and the smart door lock will fail (poor communication signal), which makes the ID judgment successful, but the decryption verification fails, causing the user to mistakenly think that the registration information of the proximity card itself is wrong

Embodiment Construction

[0045] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0046] The orientations in this embodiment are all subject to the drawings in the specification.

[0047] In the communication signal detection method between a CPU proximity card and an intelligent lock of the present invention, when the existing CPU proximity card is unlocked, the ID and the key are generally required to be successfully verified before the lock can be unlocked. However, the registration information of the proximity card is correct. In some cases, if the distance between the proximity card and the smart door lock is at a critical point, the door lock can read the ID number of the proximity card, but the magnetic field strength is not enough to support the normal communication of the internal verification. There will be a situation where communication between the proximity card and ...

Abstract

The invention discloses a communication signal detection method and system for a CPU induction card and an intelligent lock. The communication signal detection method comprises the process of judgingwhether communication between the CPU induction card and the intelligent lock is normal or not. The process comprises the steps that A, reading data in the CPU induction card through the intelligent lock; b, judging whether the communication between the intelligent lock and the CPU induction card is normal or not through the intelligent lock, and if not, responding to the step C; and C, enabling the intelligent lock to read the CPU induction card again. The invention provides the communication signal detection method and system for the CPU induction card and the intelligent lock. Whether a communication signal between the CPU induction card and the intelligent lock is stable or not is judged by carrying out reset operation and a return value of a decryption process.

Description

technical field [0001] The invention relates to the field of intelligent locks, in particular to a method and system for detecting communication signals between a CPU induction card and an intelligent lock. Background technique [0002] When the existing CPU proximity card unlocks the lock, it generally needs both the ID and the key to be verified successfully to unlock the lock. However, if the registration information of the proximity card is correct, if the distance between the proximity card and the smart door lock is a critical point, the door lock will Can read proximity card ID number. [0003] However, the strength of the magnetic field is not enough to support the normal communication of the internal verification. There will be a situation where communication between the proximity card and the smart door lock cannot be communicated (poor communication signal), which makes the ID judgment successful, but the decryption verification fails, causing the user to mistake...
