Abstract

The invention provides an interactive electromagnetic whiteboard comprising a controller connected with an A / D detecting converter. The A / D detecting converter is connected to a signal amplifying processor connected with an X-axis multiplexed electronic switch and a Y-axis multiplexed electronic switch. The X-axis multiplexed electronic switch is connected with an X-axis wire of a coordinate copper mesh, and the Y-axis multiplexed electronic switch is connected with a Y-axis wire of the coordinate copper mesh. The X-axis multiplexed electronic switch and the Y-axis multiplexed electronic switch respectively scan and detect electromagnetic signals of the X-axis wire of the coordinate copper mesh and the Y-axis wire of the coordinate copper mesh and send the electromagnetic signals to the signal amplifying processor. The signal amplifying processor filters and amplifies the electromagnetic signals and performs analog-digital conversion through the A / D detecting converter to convert the electromagnetic signals into digital signals, and the digital signals are sent to the controller to identify and process. The interactive electromagnetic whiteboard is simple in structure and high in writing speed and writing accuracy, and supports multiple users to write synchronously.

Description

[0001] Technical field [0002] The present invention involves the technology field of teaching utensils, and specially involves an interactive electromagnetic whiteboard. Background technique [0003] Electronic whiteboards have become a must -have for multimedia classrooms in major primary and secondary schools.Electronic whiteboards are favored by educational practitioners with their good interaction and perfect digital display.The teacher eliminates the pink sinking of the chalk.The structure of electronic whiteboards provided in existing technologies is complicated, with high production costs, complex production, short writing speed, low writing accuracy, and can only support one person writing. Invention content [0004] The invention provides an interactive electromagnetic whiteboard. Its simple structure, fast writing speed, high writing accuracy, and supporting multi -person writing simultaneously. [0005] In order to achieve the above goals, the present invention prov...
