The invention discloses a pretreatment-type entrance-guard lighting driving system based on an input buffering circuit. The entrance-guard lighting driving system comprises a chip judgment circuit composed of a chip U1 and a resistor R3 connected between a pin CK and a pin VDD of the chip U1 in series. The model of the chip U1 is TT6061. The entrance-guard lighting driving system further comprises a driving input circuit, an input triggering circuit, a lighting triggering circuit, a signal pretreatment circuit and the input buffering circuit, wherein the driving input circuit and the input triggering circuit are connected with the chip judgment circuit, the lighting triggering circuit and the signal pretreatment circuit are respectively connected with the input triggering circuit, and the input buffering circuit is connected with the driving input circuit. By means of the pretreatment-type entrance-guard lighting driving system based on the input buffering circuit, a lighting system is more sensitive, the response speed is increased, more timely lighting can be obtained when people adopt an entrance guard, and the use effect of the product is further improved.
Description
technical field [0001] The invention belongs to the field of building access control lighting, and specifically refers to a preprocessing type access control lighting driving system based on an input buffer circuit. Background technique [0002] Access control is a device used to protect the safety of residents. Users need to pass the authentication of access control before entering the house, which can better improve the safety of residents and at the same time prevent criminals and various social personnel from entering In residential area. In order to improve the use effect of access control, especially at night when the light is insufficient, people often use related lighting devices around the access control, but the use effect of the existing lighting device is not satisfactory, and its sensitivity is low, which is not conducive to timely Insufficient lighting can sometimes lead to misoperation by residents, ranging from being unable to open the access control normall...
