The invention discloses a 
photon entrance guard 
system based on voice control. The 
photon entrance guard 
system comprises a mobile terminal and a 
light control door lock, wherein the mobile terminal comprises a voce identification module, a control module and a sending module, the voice identification module is used for identifying voice information, the control module is used for controlling the sending module according to the identification results of the voice identification module, the sending module is used for sending 
password information through visible light signals, and the 
light control door lock is used for executing a door opening or door closing actions according to the visible light signals. Compared with an entrance guard 
system adopting fixed equipment for 
fingerprint collection or adopting direct voice identification opening, the 
photon entrance guard system based on the voice control has the advantages that the 
password information is sent through the visible light signals. Because the light signals adopt linear transmission, the 
password information cannot be easily leaked out, the 
camouflage cheating cannot easily occur, the safety is improved. The voice identification control has the characteristics of non-contact performance, non-invasive performance and easy use, so the voice identification control easily becomes popular by 
mass consumers, and the photon entrance guard system can fast occupy the markets.
