The invention discloses a method and a device for indicating a state and analyzing a fault of an access control system. The method comprises the following steps of: an operation state judging process, a user card authentication process and a communication state judging process. A central processing unit drives a first indication lamp and a second indication lamp to flicker in different ways according to access control equipment in each process. According to the method and the device for indicating the state and analyzing the fault of the access control system, disclosed by the invention, the two indication lamps are combined into a plurality of types of states to indicate the operation state and a fault phenomenon of the access control equipment, so that a problem that one indication lamp only can indicate one state is solved, further, various states and faults of the access control equipment can be indicated, and the efficiency and the accuracy of debugging and maintaining are improved.
Description
technical field [0001] The invention relates to the field of access control systems, in particular to a method and device for state indication and fault analysis of the access control system. Background technique [0002] With the enhancement of security awareness, access control, as a device for management personnel to enter and exit, has been more and more used in various confidential departments, such as banks, hotels, computer rooms, armories, confidential rooms, office rooms, intelligent Chemical districts, factories and other security places. It integrates microcomputer automatic identification technology and modern safety management measures, involving many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology. Access control equipment needs to deal with a large number of input and output signals, data processing and communication. Such as figure 1 As shown, the existing access control equipment st...
