An intelligent detection device is mounted on an inner handle of a door, whether the inner handle of the door is rotated is detected through a rotation detecting device, whether the door is moved is judged through a gyroscope mounted on the door if the inner handle of the door is rotated, and the situation that a user unlocks the door from the inside of the door can be judged if the door is moved. Next, whether a visitor stands outside the door can be judged through a digital door viewer, and the situation that the user is to go out can be determined if no visitor stands outside the door. Then, the digital door viewer acquires a to-be-noticed message of the user and broadcasts the to-be-noticed message of the user or pushes the to-be-noticed message of the user to a terminal device of the user. Accordingly, whether the user is to go out can be intelligently judged, a reminding service can be provided for the user before the user goes out, the user can be reminded of unfinished items, outdoor weather conditions or traffic conditions, great convenience is brought for the user who is to go out, and the user experience is improved.
