Bang Young said | Nandue Youth will take you to "play" science and technology

The road of youth requires good examples and driven by good companions. In recent years, a number of youth examples have emerged in the practical education of Communist Youth League such as "Challenge Cup", "Sanxiangxiang", and "Return to Hometown". The Youth Development Department of the Youth League has launched a column of "Bang Young" to tell their youth struggle story.

The exhibition invited the 13th "China Youth Science and Technology Innovation Award" winner, from Liu Hangyu, a senior classmate at Yixi Middle School, Xiangqiao District, Chaozhou City, Guangdong Province.

Let's listen to his innovative story together

Liu Hangzhang is an irreplaceable backbone force for the school's science and technology team. He often participates in various competitions at all levels and has achieved good results. He focuses on science and technology, has forward -looking consciousness, explore spirit, has the ability to do hands, and closely combines life with learning, and serves the society.

Liu Hangzhang has a strong interest in computer production and robots since he was a child. He began to come into contact with programming in the fourth grade of elementary school and like to create a variety of small games and practical apps. Entering junior high school, Liu Hangzhang joined the school's maker club, conducted a deeper study of programming, and began the road of scientific and technological innovation combining programming and hardware. From Mixly to Arduino to Python and C language, various programming software must be handy. With the hot pillow of scientific and technological innovation, Liu Hangyi likes to ask more about "why" and find a solution. Seeing that when the society entered the room theft, there was a situation where the security performance of the family door lock was not high. Liu Hangzhang developed a door lock that can convert the password into a light signal and high security performance -photon secret. The photon secret key uses only two simple LED lights, and uses wavelength and encoding technology to compile a password for the lock. The password information is sent through visible light signals, which is not easy to steal and copy, bringing a new concept to home security.

Later, Liu Hangyu was interested in creating intelligent and safe living equipment, and created works of smart home, smart street lights, and smart campuses. His work "Smart Robot" will interact with the owner, can sing, tell jokes for the owner, and make a simple conversation. When the owner is not at home, he will automatically patrol. Mobile phone report dangerous situation. In the environment of raging epidemic, in order to improve the management of epidemic prevention safety, he has created the "intelligent epidemic prevention goalkeeper".

Create "AI Smart Fish", collect hundreds of fish activities collected, and then write programs to train the camera to achieve the purpose of intelligent identification and judgment

Gradually, Liu Hangyu was dissatisfied with some models of works. He always thought about whether he could create equipment that can actually be used in real life, so that technological innovation brought more convenience to life. Therefore, under the guidance of the teacher, he created the "Internet+Smart Agricultural" technology breeding equipment, using IoT technology, using soil temperature and humidity sensors and water pH sensors, air quality sensors, etc. With the degree of water and acidic acid and alkali, write the intelligent agricultural Internet of Things system to achieve functions such as automatic prediction, intelligent decision -making of irrigation water volume, remote/automatic control of irrigation and fishing equipment.

The "Internet+Smart Agricultural" technology breeding equipment created by Liu Hangzhang is now applied to school plantation management

As one of the technical backbones of the school's science and technology team, Liu Hangyi is courageous to innovate, learn to use, and set up to solve practical problems in life, serve the society and serve others. Through observations in life, Liu Hangyu found that the school's public toilet often produced an unpleasant odor due to cleanliness in time and needed a smart device that can effectively filter harmful gases in the air. With such an idea, he kept consulting the information to understand the main ingredients and sources of the odor of the bathroom. At the same time, in order to obtain more scientific data, he uses ammonia sensors and programs to write a odor index monitoring instrument, collecting the odor index of the school bathroom for several days, especially the peak period and low peak period of the bathroom, and just cleaning Later bathroom odor index. The collected data is used for artificial intelligence training for the ammonia module to achieve environmental value processing and graphically display. Use Arduino's language environment to upload environmental values ​​such as the odor data collected by the ESP32 single -chip microcomputer to the background of the "equipment cloud" to achieve remote monitoring and control through the mobile Internet of Things. A smart equipment creation process of filtering the harmful gases of public toilets

Liu Hangyu not only keen to science and technology, but also drove the classmates around him to "play" science and technology. He is diligent in learning, actively developing. With optimism and learning, unity and friendship, etc., he gives full play to the radiation role of outstanding students, stimulating and driving a group of students who "like -minded" blooming gorgeous glory on the stage of science and technology innovation.

Liu Hangyu participated in the special training camp organized by the Science and Technology Innovation Summer Camp organized by the Guangdong Science Center

Innovation is the soul of a nation's progress, and the inexhaustible motivation of the country's rise and fall. Liu Hangzhang feels that the teenagers of the new era must first dare to innovate. Without innovation, they can only live in the rules of others. They will never make breakthroughs. Secondly, it is necessary to achieve their bold ideas and break through existing technology. Liu Hangzhang is using practical actions to interpret the spirit of innovation and young people in the new era.
