Eight-door double-controlling high-capacity access controller

An eight-door double-controlling high-capacity access controller comprises, according to functional partitioning, a power supply unit (1), a core unit (2), a communication unit (3), a complex programmable logic device/field programmable gate array (CPLD/FPGA) logical unit (4), an input/output (I/O) interface unit (5) and a WG26 interface unit (6). The access controller has the advantages that application environments in which the security control grade requirement is high, identification card-reading devices are needed to be arranged widely and a large number of administrators are needed can be satisfied; and simultaneously, the identification efficiency of identity information is high, information retrieval and feedback efficiency is high, the information storage capacity is large, reliability is high, comprehensive wiring is reasonable, the cost is low, and the like.
