Authors: Wang Zuliang , Wang Shaofei , Shi Zhao
Published: February 2021

In order to avoid the risk of suffocation in the car for children and other vulnerable groups, an alarm system based on single chip microcomputer is designed. Arduino UNO R3 is used as processor, and hc-sr501 human body infrared sensor, sound and light alarm module, A6 GSM communication module, DC motor and l9110s motor drive board are used. When it is detected that a person in the vehicle is locked and in a closed environment, the alarm information is sent to the emergency contact person and the skylight is forced to open for ventilation. If the vehicle does not have a skylight, the vehicle itself will send an alarm to attract passers-by’s attention, so as to rescue the passers-by in case of emergency, so as to prevent the personnel in the vehicle from suffocating.

Design of Simulated Magnetic Gun
Authors: Huang Jian
Published: February 2021

STM32F103 single-chip microcomputer is used as the control unit of the simulated electromagnetic squint. The single-chip microcomputer is used to control the function of launching shell and steering gear angle, and the steering gear is used to control the launching angle and direction of the electromagnetic squint. In the design of electromagnetic gun, coaxial coil gun is used as the main part, and two batteries are used as the energy supply device. Then the electromagnetic relay connected with the single-chip microcontroller controls the cycle charging. Firstly, 12V DC power is input into the circuit by the DC stabilized voltage power supply. After the current enters into the circuit, it is divided into two branches. One branch flows through the boosting circuit of electromagnetic relay to charge the thyristor capacitor. With the switch off, the instantaneous discharge of the capacitor generates an inverter magnetic field in the coil, which pushes the metal projectile out at a high speed. What the electromagnetic relay does is to boost the voltage. What the thyristor capacitor needs is high voltage current charging. Another branch supplies 5V DC power to the steering gear through the step-down electromagnetic relay to support the rotation of the steering gear. The system obtains the target position through openmv, and STM32 uses PWM wave to control the rotation angle and direction of the steering gear.

Published: February 2021

“The key feature of project-based learning is that students develop autonomy and responsibility for their learning.” But how to support students with “newly gained freedom and autonomy”to“overcome and solve their problems and difficulties”[1]is still a challenging question to students and teachers. This paper aims to develop a self-help learning and instructing framework shared by teachers and students, which will be a digital application prototype to assist teachers to provide guidance and support for students to overcome learning difficulties by themselves in project-based learning. The results of students questionnaire show that the self-help framework is an effective way of fostering students’ learning skills such as cooperation, communication and reflection, which defined by PBL. More importantly, it freed teachers from ‘teaching’ knowledge and skills to observing, auditing, reacting from time to time with students as a more democratic role, in which students got more chances to learn by themselves in classroom, in another word, more actively, autonomously and independently.

Authors: Yue Chunxiu
Published: February 2021

We will find a phenomenon that many parents in China are very concerned about their children’s public English performance. Although both mathematics and Chinese are major subjects, English has a very high status in people’s hearts. On the whole, this phenomenon is caused by the trend that our country is moving towards internationalization. English has become a necessary subject for every student. Even many parents think that the importance of English should be higher than that of Chinese. Although this argument is one-sided, it also reflects the importance of parents on English. In view of today’s educational forms, the situation where computers are used in classroom teaching is very extensive. How to use computer technology to innovate in public English teaching has become a concern of every higher vocational college. I believe its reform and innovation will write a new chapter in China’s English education.

At the same time, due to the different foundation of students, it is difficult for coaches to teach students in accordance with their aptitude. At the same time, based on the objective factors such as the angle and position of table tennis, the coach’s judgment may be biased, which leads to the realization of 3D table tennis simulation animation based on computer. Through 3D table tennis simulation animation, we can not only improve the shortcomings of traditional table tennis teaching, but also make table tennis teaching more modern. Therefore, this paper first analyzes the movement principle of table tennis. Then, this paper designs the visual servo control system, which can better watch the entity training. Finally, this paper proposes the implementation method.
