smart blackboard

Abstract

The invention discloses an intelligent blackboard, belongs to the technical field of efficient utilization of mechanical blackboards, and aims at solving the problems that two blackboards cannot be alternately used and cannot be automatically erased. The intelligent blackboard comprises an erasing system and a switching system, wherein the switching system and the erasing system are fixed on the wall respectively; the erasing system comprises a moving unit and a centrifugal telescopic unit; the moving unit enables a long rod erasing head to move in the vertical and horizontal directions; the centrifugal telescopic unit enables the long rod erasing head to perform telescopic movement on the blackboard in the normal direction; the switching system enables the positions of a front-end blackboard and a rear-end blackboard to be switched; the long rod erasing head can be in contact with the front-end blackboard and the rear-end blackboard. The intelligent blackboard has the advantages that the two blackboards can be alternated, and the fixed area of the blackboard can be automatically erased by virtue of the cooperation of a singlechip microcomputer and peripheral equipment; the blackboard can be quickly, sanitarily, accurately and efficiently erased, and the maximum using efficiency is obtained.

Description

technical field [0001] The invention relates to an intelligent blackboard for automatic fixed-area erasing, which belongs to the technical field of high-efficiency utilization of mechanical blackboards. Background technique [0002] The blackboard is a tool that is often used in learning and office work, but the existing blackboards often have the following problems. [0003] 1. The blackboard is usually placed left and right. After a certain distance, sitting on both sides of the blackboard and looking at the blackboard will cause total reflection. Such a problem requires us to use a new blackboard alternation method. 2. The task of cleaning the blackboard is heavy, and a large amount of dust is generated to cause harm to the human body. A device that can efficiently erase the blackboard is needed. In the existing market, there are blackboards that can be exchanged up and down for the first type of problem, and blackboard erasers for the second type of problem, but there ...
