In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The principle of the smart pen case for electronic whiteboard provided by the present invention is as follows

The main body of the whiteboard touch frame is arranged around the electronic whiteboard to realize the touch function of the electronic whiteboard. The smart pen box is installed under the electronic whiteboard and connected to the electronic whiteboard through a connecting line. The built-in circuit board of the smart pen box senses the actions of different writing pens through magnetic induction, so as to realize the free switching of note colors.

FIG. 1 is a schematic diagram of the connection between the smart pen box and the electronic whiteboard according to the embodiment of the present invention. As shown in FIG.

The smart pen case 2 includes a writing pen 4, a support frame, a pen case body and a data line; the writing pen 4 is a magnetic writing pen.

The pencil box body includes a shell, an RS sensor, a pencil box circuit controller connected to the RS sensor, an electronic whiteboard touch processor connected to the pencil box circuit controller, a DA data line, a CL data line, and a pull-up resistor. Among them, the RS sensor, the pen box circuit controller, the electronic whiteboard touch processor, the DA data line, the CL data line, and the pull-up resistor are all arranged inside the shell.

The support frame is installed on the outside of the shell, and the support frame is set corresponding to the RS sensor; the writing pen 4 is placed on the support frame.

The pen case circuit controller is connected with the touch processor of the electronic whiteboard through the DA data line and the CL data line.

One end of the RS sensor is connected to the pen case circuit controller through a data line, and the other end is grounded; one end of the pull-up resistor is connected to the high-level power supply, and the other end is connected to the pen case circuit controller; the pull-up resistor and the pen case circuit controller The connection end is the same connection end as the connection end of the RS sensor and the pen box circuit controller; the high level power supply is +5V power supply.

There are multiple writing pens 4 , RS sensors, and pull-up resistors, and the number of writing pens 4 is the same as the number of RS sensors and the number of pull-up resistors. Preferably, there are four writing pens 4, which are respectively green, yellow, purple and orange, and there are also four RS sensors and pull-up resistors.

A whiteboard touch frame is arranged around the electronic whiteboard 3 for realizing the touch function of the electronic whiteboard.

When the writing pen 4 leaves the support frame, the RS sensor is in a short-circuit state, the corresponding data line 5 will have a voltage change, from low voltage to high voltage, and the pen box circuit controller detects the voltage change of the corresponding data line 5, so that The writing mark currently in operation transmits the detection data to the electronic whiteboard touch processor through the DA data line and CL data line. The electronic whiteboard touch processor realizes the switching of different note colors according to the detection data transmitted by the pen case circuit controller. operate.
