Access Control Unit (ACU) system is one of advanced security facilities accepted by modern buildings, which is regarded as an important symbol of modern building’s intelligence. Embedded operating system of
μ
C/OS-II equipped with TCPIP protocol is transplanted into LPC2214 controller, from which two kinds of communication types (TCPIP & RS485 ) are achieved in ACU. The ACU has not only normal access control functions, but also a series of complicated functions such as anti-trail, anti-hide, anti-intimidate, remote open door and so on, which can satisfy different customer’s requirement.
