[ Huaqiang Security Network News ] Through its own unique advantages, the current access control system has been applied in many domestic occasions. Among them, the access controller as the main core content also plays an important role. For the access control system, To a certain extent, the quality of the access controller determines its main performance characteristics, so the principle of the access controller must be widely known. 
Generally, the access controller will be implemented in a split structure. The main purpose is to receive the correlation through a card reader installed near the door. According to certain rules, the code is judged. It is necessary to know that the access controller will appear according to the As a result, the corresponding operation is taken, and according to the user's demand, the access controller can also be connected to an external peripheral such as an alarm sensor to complete the relevant security requirements.
The access controller generally works in two modes, one is the patrol mode, and the other is the recognition mode. During the patrol process, the access controller continuously sends the query code to the reader. To receive the reply command of the card reader until the card is sensed, through the relevant workflow, we can achieve the result of opening the door.
The security performance and reliability of the access controller can be uniformly detected and managed to achieve the best application state, so that the access control system can play a greater role.
