Abstract

The invention relates to the technical field of intelligent locks, in particular to an intelligent lock delay circuit. The circuit comprises a key entity switch arranged at the positive electrode end and a reset switch arranged at the negative electrode; a 3.3 V voltage is adopted in the circuit, a resistor R12 is connected to the positive electrode, a capacitor C83, a capacitor C82 and a resistor R23 are connected to the resistor R12 in parallel, a resistor R24 is connected to the resistor R12, an NMOS tube Q2 is connected to the resistor R24, the NMOS tube Q2 is connected with a resistor R29 and a resistor R31 which are mutually connected in parallel, the resistor R31 is connected with an NMOS tube Q3, an output end of the NMOS tube Q3 is connected with a resistor R34 and an NMOS tube Q5 which are mutually connected in parallel, output ends of the resistor R34 and the NMOS tube Q5 which are mutually connected in parallel are connected with a capacitor C84 and a resistor R51, the resistor R51 is connected with an LED lamp, an output end of the LED lamp is connected with a reset switch, an output end of the capacitor C84 is connected with a capacitor C85, and the capacitor C85 is connected in parallel with a resistor R37 and a resistor R40 which are connected in parallel with each other. The circuit is low in cost, safe and stable, and the intelligent lock system can be reset through the circuit when the software function is abnormal.

Description

technical field [0001] The invention relates to the technical field of intelligent locks, in particular to an intelligent lock delay circuit. Background technique [0002] Smart door lock refers to a lock that is improved on the basis of being different from traditional mechanical locks, and is more intelligent and simple in terms of user security, identification, and management. The smart door lock is the executive component for locking the door in the access control system. Different from traditional mechanical locks, smart door locks are composite locks with safety, convenience and advanced technology. Magnetic card, radio frequency card (non-contact type, high security, plastic material, easy to configure and carry, low price) using non-mechanical key as a mature technology for user identification ID, such as: fingerprint lock, iris recognition access control (biometric identification, High security, no loss or damage; but inconvenient to configure, high cost) TM card ...
