Title:
INFRARED ACCESS CONTROL DETERMINATION METHOD AND INFRARED ACCESS CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/125047
Kind Code:
A1
Abstract:
Disclosed is an infrared access control determination method, applied to an infrared access control device. An infrared access control device (30, 40) comprises M infrared emitting units (301, 402) and M infrared receiving units (302, 403), wherein the M infrared emitting units (301, 402) and the M infrared receiving units (302, 403) are correspondingly arranged, and when a jth infrared receiving unit of the M infrared receiving units (302, 403) does not receive a signal sent by a corresponding infrared emitting unit, a jth infrared trigger signal is sent. The infrared access control determination method comprises: initializing a system (S101); determining whether a first signal is received (S102); if so, determining the type of the first signal (S103); if the first signal is a first infrared trigger signal, assigning the value of 2 to i and assigning the value of 2 to j (S104); determining whether an ith signal is received within a first pre-set time (S105); if so, determining the type of the ith signal (S106); if the type of the ith signal is a jth infrared trigger signal and if j is not equal to M, assigning the value of i+1 to i and assigning the value of j+1 to j, and continuing to determine whether the ith signal is received within the first pre-set time (S105); and if j is equal to M, completing verification (S1010).
