The invention provides a community intelligent passing control system and method based on narrow band Internet of Things and belongs to the technical field of Internet of Things. The system is an intelligent wireless control system composed of a narrow band Internet of Things (NB-IoT) communication technology, a network technology, a cloud technology and a control technology and is applied, but not limited to the fields including elevators, access control, parking lots and the like of a community. The system is a whole set of solution for community intelligent passing. The system comprises a mobile terminal (APP (Application) or a Wechat applet) of a user, a property management platform, a cloud server, an NB-IoT communication module, a controller, an expansion board, a license plate recognition camera and a two-dimensional code display device. Compared with other methods, the system has a plurality of incomparable advantages of massive connection, deep coverage, ultralow power consumption, low cost, stability and reliability and the like; the system is an only technical solution for realizing effective communication in scenes with relatively weak signal coverage; and furthermore, an owner can pay property management fee, car parking fee and the like through a cell phone, and troubles that the owner goes to a property management center back and forth are avoided.
