Origami-Based Single-Chip Microcomputer: Intelligent Timing Switch Design

智能定时开关随着智能化、自动化技术的快速发展受到了广泛的关注，其应用也越来越广。本文针对需要自动定时开通关断的场景，设计了基于AT89C52单片机的智能定时开关，该设计通过两个按键实现定时开启、定时关闭功能，利用PWM控制技术，通过调节其占空比，使其输出不同的波形，驱动三极管的开通和关断，满足不同要求的智能开通和关断功能，提高了智能开关的稳定性。利用Proteus软件进行了仿真实验，观测电平波形图，验证了该方法的有效性。
Intelligent timer switch with the rapid development of intelligent, automation technology has received widespread attention, and its application is becoming more and more widespread. In this paper, for the scene that requires automatic timed opening and closing, we designed an intelligent timed switch based on AT89C52 microcontroller, which is designed to realize the timed opening and closing functions through two buttons and utilizes the PWM control technology to drive the opening and closing of the transistor with different waveforms by adjusting the duty cycle, so as to satisfy the intelligent opening and closing functions of different requirements, and to improve the stability of intelligent switch. Simulation experiments were carried out using Proteus software, and level waveforms were observed to verify the effectiveness of the method.
