Detailed ways

It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

In order to realize the requirement of identifying the color of the watercolor refill by the lattice intelligent watercolor pen, the present invention provides an automatic color recognition system of the lattice intelligent watercolor pen, as shown in FIG. 1 ,

The system includes color identification components and color identification components,

The color identification component is used to store the color information of the watercolor refill,

The color identification component is used for identifying the color identification component, so as to obtain color information of the watercolor refill.

In one of the preferred embodiments, the color identification component is an RFID/NFC tag, and information in a fixed format is programmed on the RFID/NFC tag, and the information represents different colors, and the color identification component is an NFC reader. Card circuit.

Wherein, the RFID/NFC tag is placed at the end of the dot matrix smart watercolor pen watercolor refill.

Wherein, the NFC card reader circuit is placed on the dot matrix smart watercolor pen circuit board.

In another preferred embodiment, the color identification component is card stock, and there is coded information on the card stock, and different information represents different colors; the color identification component is an identification camera, and the camera is used to photograph the ink on the refill. card stock and decode the information on the paper.

Wherein, the encoded information includes dot matrix information, barcode and/or two-dimensional code, and different graphics.

In a preferred embodiment, a method for automatic recognition of the replacement of the watercolor refill of a dot matrix smart watercolor pen is proposed. A magnet is placed on the watercolor refill, a magnetic sensor chip is placed on the circuit board, and the refill is inserted and placed After that, the magnet is just below the magnetic sensor chip, when the magnetic sensor chip detects the magnet, the magnetic sensor chip outputs a level (low level), when the refill is pulled out, the magnetic sensor chip cannot detect the magnet, the sensor Output another level (high level), so that the action of replacing the refill can be recognized by this method, and when the action of replacing the refill is recognized, the color recognition is triggered.
