Intelligent pen energy-saving method

Abstract

The embodiment of the invention discloses an intelligent pen energy-saving method, which belongs to the technical field of intelligent pens, and comprises the following steps: arranging a first pressure switch at the tail end of an intelligent pen; arranging a second pressure switch at the tail of a refill of the intelligent pen, and when the pressure of the nib during writing on writing paper exceeds a preset threshold value, the second pressure switch generates a trigger signal; connecting a first processor interface of the intelligent pen processor with a second end of the first pressure switch; after the processor finishes the self-checking process, enabling the processor to further judge whether the second pressure switch is in a conducting state or not; if yes, enabling the processorto control an infrared receiving and transmitting circuit on the intelligent pen to transmit an infrared light signal to a writing paper area of the intelligent pen, and further determining the writing trace of the intelligent pen on the writing paper by reading a reflection signal of the infrared light. Through the scheme of the invention, energy-saving operation can be performed on the intelligent pen based on different states of the intelligent pen.

Description

technical field [0001] The invention relates to the technical field of smart pens, in particular to an energy-saving method for smart pens. Background technique [0002] Writing is a wonderful experience. Writing on paper always has a charm. Even in the information age, people are always eager to save handwritten notes. Especially in terms of smart education, when black technologies such as electromagnetic writing recognition, infrared dot matrix recognition, and ultrasonic recognition are integrated into writing, there will be a variety of smart writing pens. [0003] In the prior art, since there are many components in the smart pen, in the process of using the smart pen, the battery capacity of the smart pen itself is low, and at the same time there are many components of the smart pen itself, resulting in a large power consumption of the smart pen. The battery power of the smart pen cannot support the battery life of the smart pen for a long time, which affects the user...
