Preprocessing-type access control intelligent power supply illumination driving system based on input buffer circuit

Abstract

The invention discloses a preprocessing-type access control intelligent power supply illumination driving system based on an input buffer circuit. The system comprises a chip determination circuit, adriving input circuit, an input trigger circuit, a self-prompted power supply switching circuit, a trigger illumination circuit, a signal preprocessing circuit and the input buffer circuit, wherein the chip determination circuit is formed by a chip U1 and a resistor R3 which is connected in series between a CK pin of the chip U1 and a VDD pin; the model of the chip U1 is TT6061; the driving inputcircuit and the input trigger circuit are connected to the chip determination circuit; the self-prompted power supply switching circuit is connected to the driving input circuit; the trigger illumination circuit and the signal preprocessing circuit are connected to the input trigger circuit; and the input buffer circuit is connected to the driving input circuit. By using the preprocessing-type access control intelligent power supply illumination driving system based on the input buffer circuit, power supply of the system is guaranteed, stability of system operation is increased, an illumination system is sensitive and a reaction speed is increased. When people use access control, timely illumination can be achieved so that a usage effect of a product is further increased.

Description

Technical field [0001] The invention belongs to the field of building access control lighting, and specifically refers to a pre-processing type access control intelligent power supply lighting drive system based on an input buffer circuit. Background technique [0002] The access control is a device used to protect the safety of the residents. The user needs to pass the authentication of the access control before entering the residence. This can better improve the safety of the residents’ living, and at the same time, it can also avoid the intrusion of criminals and various social personnel. Residential area. In order to improve the use effect of the access control, especially when there is insufficient light at night, people often use related lighting devices around the access control. However, the use effect of the existing lighting devices is not satisfactory, and its sensitivity is low, which is not conducive to timely Even if the lighting is insufficient, it may cause misop...
