Find out the characteristic data generated when the pen is lifted in the middle of writing two words, count it, and then display the counting result on the LCD screen. The initialization button on the pen holder determines whether to clear the recorded word count. The present invention can realize full-automatic recording of the number of written words through pressure detection; it can operate fully automatically and hardly needs human control. It is convenient for those who need to record the word count accurately when writing.

Description

A pen capable of automatically recording the number of written words and its method

technical field

The invention belongs to the field of daily necessities, and relates to a pen capable of automatically recording the number of written words and a method thereof.

Background technique

Pen is an essential thing in people's life. In some fields, there is no quick and convenient way for users to know how many words they have written. In some special purposes, it is very necessary to know the number of written words quickly and in time. Some grid paper can count the number of words written according to the writing, but it is not accurate and timely enough, and it is inconvenient to carry. If there is a pen that can automatically record the number of words, it will greatly facilitate people to obtain and record the number of written words, and it is easy to carry and update in real time.

Everyone's writing habits are different, but since I started to practice calligraphy with grid paper, I always have the habit of raising the pen to write the next character after writing a character, and this time the transition between raising the pen and the strokes in a character Picking up a pen makes a difference.

The inclination of the pen and the distance from the pen tip to the paper can be obtained from the data collected by the distance sensor through analog-to-digital conversion, and the characteristic data segment generated when changing from one character to another can be obtained through a certain algorithm. So as to achieve the function of counting words.

Contents of the invention

In order to facilitate people to record the number of words written by themselves and save people's time to a certain extent, the invention can automatically record the number of written words. In order to achieve the above object, the technical implementation scheme of the present invention is as follows:

The pen capable of automatically recording the number of written words of the present invention includes: a pen body, a pressure sensor, an ultrasonic distance sensor, an initialization button and a power supply module.

A pressure sensor, installed in the lower part of the pen body, is used to wake up the control system;

Ultrasonic distance sensor, installed at the tip of the pen cap, used to sense the distance between the pen and the paper;

The initialization button is used to send initialization instructions to the control system;

LCD screen, used to display the word count information processed by the control system;

The control system is used to receive the information collected by the ultrasonic distance sensor, count the word count information; and clear the recorded word count according to the instruction of the initialization button.

The power module is a lithium battery, and the end of the pen body is provided with a charging interface.

There are multiple pressure sensors, and only after the pressure sensors exceeding the set amount feel the pressure exceeding the pressure threshold, a signal to wake up the control system is generated; when all the pressure sensors do not sense pressure within the set time, a Dormancy signal, the control system enters the dormancy state.

The word count recording method of the pen:

When the pressure sensor on the pen holder senses that the user is holding the pen, it wakes up the control system in the dormant power-saving state, and the control system enters the working state; the ultrasonic distance sensor collects distance information, and the control system filters and analyzes the collected distance information. Find out the characteristic data generated when the pen is lifted in the middle of writing two words, count it, and then display the counting result on the LCD screen. The initialization button on the pen holder determines whether to clear the recorded word count.

The beneficial effect of the present invention is that it can realize automatic recording of the number of written words through pressure detection; it can operate fully automatically and hardly needs human control. It is convenient for those who need to record the word count accurately when writing. The present invention is suitable for users who write regular script and running script, but not for users who write cursive script.

detailed description

In the following, the present invention will be further described according to specific implementation examples and in conjunction with the accompanying drawings, so as to make the technical means, effects, etc. of the realization of the present invention easier to understand.

The pen capable of automatically recording the number of written words of the present invention includes: a pen body, a pressure sensor, an ultrasonic distance sensor, an initialization button and a power supply module.

A pressure sensor, installed in the lower part of the pen body, is used to wake up the control system;

Ultrasonic distance sensor, installed at the tip of the pen cap, used to sense the distance between the pen and the paper;

The initialization button is used to send initialization instructions to the control system;

LCD screen, used to display the word count information processed by the control system;

The control system is used to receive the information collected by the ultrasonic distance sensor, count the word count information; and clear the recorded word count according to the instruction of the initialization button, and the control system includes a single-chip microcomputer and a peripheral clock.

The power module is a lithium battery, and the end of the pen body is provided with a charging interface.

There are multiple pressure sensors, and only after the pressure sensors exceeding the set amount feel the pressure exceeding the pressure threshold, a signal to wake up the control system is generated; when all the pressure sensors do not sense pressure within the set time, a Dormancy signal, the control system enters the dormancy state.

The word count recording method of the pen:

When the pressure sensor on the pen holder senses that the user is holding the pen, it wakes up the control system in the dormant power-saving state, and the control system enters the working state; the ultrasonic distance sensor collects distance information, and the control system filters and analyzes the collected distance information. Find out the characteristic data generated when the pen is lifted in the middle of writing two words, count it, and then display the counting result on the LCD screen. The initialization button on the pen holder determines whether to clear the recorded word count.

The above-mentioned embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Various changes and modifications can be made by those skilled in the relevant technical fields without departing from the spirit and scope of the present invention. All technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
