Blackboard writing wiping device for automatically positioning working area on basis of teaching pole controller

Abstract

The invention relates to a blackboard writing wiping device for automatically positioning a working area on the basis of a teaching pole controller, and belongs to the field of teaching auxiliary devices. The blackboard writing wiping device comprises a writing board. Guide rails are arranged on the upper side and the lower side of the writing board and connected with motors and are divided into the X-axis guide rail and the Y-axis guide rail. The Y-axis guide rail can move on the X-axis guide rail. The X-axis guide rail and the Y-axis guide rail are connected with the X-axis motor and the Y-axis motor respectively. An ultrasonic receiver and a controller are arranged on one side of the writing board. The blackboard writing wiping device further comprises the teaching pole controller which comprises a teaching pole. A power supply, a radio transceiver, a circuit board and an ultrasonic transmitter are arranged in the teaching pole. The power supply, the radio transceiver and the circuit board are connected in series to form a circuit. Through ultrasonic and radio positioning and microprocessor calculation, the coordinates of a fixed point at which the teaching pole controller points can be accurately and rapidly determined, and the wiping area is determined; the structure is simple, use is convenient, labor and resources are saved, and the environment protection function is achieved.

Description

technical field [0001] The invention belongs to the field of auxiliary devices for teaching, and in particular relates to a blackboard writing wiping device for automatically positioning a working area based on a teaching rod controller. Background technique [0002] Chalk is a tool to spread culture, but also a drug that harms the body. How many spiritual teachers suffer from chronic diseases due to repeated dust pollution and inhalation of the air duct, and leave the platform prematurely. Although the state has been using subsidies to make up for the harm of this occupational disease to teachers, it is difficult to compensate for life with money. Students sitting in the front row are also threatened by dust. This is a difficulty that the scientific community has been unable to overcome for a long time. From the so-called dust-free chalk, fine dust chalk to the development of new blackboards, there is a deep humanistic care and helplessness. [0003] The current blackbo...

Problems solved by technology

[0003] The current blackboard eraser has an automatic blackboard eraser that can control the switch to wipe off the chalk on the blackboard without manual wiping. However, the current blackboard eraser can only wipe the entire blackboard at one time, and cannot wipe a certain area. waste of time and resources
