Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] This embodiment provides a new type of blackboard, including a blackboard 1, the blackboard is provided with a dust monitoring circuit 2, in order to monitor the dust density around the blackboard; the dust monitoring circuit includes a micro control unit and connected to it A dust sensor for collecting dust density and an LED light for alarm prompt.

[0012] In this embodiment, the dust monitoring circuit is arranged at the upper right corner of the blackboard.

[0013] In this embodiment, the micro control unit is a single chip microcomputer.

[0014] In this embodiment, when the teacher wipes the chalk on the blackboard during the teaching process, if the current dust density in the air exceeds the threshold set in the micro-control unit, the micro-control unit controls the buzzer to give an alarm hint.

[0015] The above descriptions are o...

Abstract

The invention relates to a novel blackboard. The blackboard comprises a blackboard body, and a dust monitoring circuit is arranged on the blackboard body and used for monitoring the density of dust around the blackboard body; and the dust monitoring circuit comprises a micro-control unit, a dust sensor connected with the micro-control unit and used for collecting the dust density, and a buzzer used for giving an alarm prompt. According to the blackboard, the prompt can be given when the dust exceeds the standard.

Description

technical field [0001] The invention relates to the field of education and teaching, in particular to a novel blackboard. Background technique [0002] During the teaching process, when the teacher wipes the chalk on the blackboard, the dust on the blackboard will spread into the air, causing health hazards to the body. Contents of the invention [0003] In view of this, the object of the present invention is to propose a novel blackboard capable of prompting when the dust exceeds the standard. [0004] The device of the present invention is realized by the following scheme: a new type of blackboard, including a blackboard, and a dust monitoring circuit is arranged on the blackboard to monitor the dust density around the blackboard; the dust monitoring circuit includes a micro control unit and It is connected with a dust sensor for collecting dust density and a buzzer for alarm prompt. [0005] Further, the dust monitoring circuit is arranged at the upper right corner of...
