Abstract

The invention provides a detector for objects inside a box. The detector comprises a camera, an image comparison device, a controller, an alertor, a base plate and an object detecting device. The camera is arranged above a box opening, and the camera, the image caparison device and the alertor are respectively connected with the controller electrically. The base plate is arranged on the bottom of the box in an inclined mode in the diagonal direction of a box body, the object detecting device is arranged at the lowest position of the base plate, and the object detecting device is electrically connected with the controller. Every time a box door is opened, the camera can be triggered to conduct photographing once on a scene inside the box, photos which are taken are transmitted to the image comparison device through the controller, the image comparison device conducts comparison analysis on two adjacent photos before and after, and if the comparison result is that the two photos before and after are different, the alertor is triggered through the controller to warn and indicate that an object is placed into the box. According to the technical scheme, the detector for the objects inside the box is improved, and the non-dead-angle detector for objects inside the box is provided.

Description

technical field [0001] The invention relates to a detector, in particular to a detector for objects in a box. Background technique [0002] The storage box is often equipped with a detector, which is used to make a prompt function when an item is put in the box. Existing storage boxes mostly use infrared detection, that is, an infrared probe is installed at the bottom of the box. When an item is put in, the infrared rays emitted by the infrared probe will be reflected back, so that the item can be sensed. However, no matter how close the infrared probe is installed to the bottom of the box, there will always be dead spots that cannot be detected. For example, when very thin paper or small items are put in, the infrared probe will often not detect it. Therefore, how to provide an object detector without dead ends is a problem worth solving. Contents of the invention [0003] The object of the present invention is to solve the problem of how to provide an item detector in ...
