[0002] The access control system is to control the locking and opening of the doors in various passages that can pass through, and to control the entry and exit of vehicles and people in various places. Various access control systems are usually installed on construction sites to control the entry and exit of vehicles and other idlers. For temporary access control, cable installation is required, which takes a long time. On the other hand, after the construction period is over, the access control needs to be disassembled, which is easily damaged and cannot be used again
