Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in figure 1, the invention provides a system for identifying the replacement of a watercolor refill of a dot matrix intelligent watercolor pen, which comprises
Comprises a magnet and a magnetic sensor chip, wherein the magnet is arranged on a water color refill of the dot matrix intelligent water color pen, the magnetic sensor chip is arranged on a circuit board,
after the watercolor pen core is inserted and placed, the magnet is just under the magnetic sensor chip;
when the magnetic sensor chip detects the magnet, the magnetic sensor chip outputs one level, when the watercolor refill is pulled out, the magnetic sensor chip cannot detect the magnet, the sensor outputs the other level, and the action of replacing the refill is identified through the level conversion.
After recognizing the above-mentioned action, adopting one of the following modes to make color recognition:
the first method comprises the following steps: when the watercolor refill is inserted, the NFC card reader circuit identifies the label, reads the color information of the label and transmits the information to the main control chip; after the refill is replaced, the NFC card reader circuit identifies different color information and sends the information to the main control chip, and therefore automatic identification of the refill color can be achieved.
And the second method comprises the following steps: the tail end of the watercolor refill is provided with cardboards, the cardboards are provided with coded information (including and not limited to dot matrix information, bar codes, two-dimensional codes, different patterns and the like), different information represents different colors, the main board is provided with the camera, the camera shoots the cardboards on the refill and decodes the information on the cardboards, the decoding result is provided for the main control chip, different information can be obtained by replacing different refills, and automatic identification of the refill color is realized.
