This paper designs a solar energy adaptive window controller based on STC15 series single chip computer, and the system runs well. 　　At present, the most widely used windows are still the most primitive way of manual closure. They do not have the humanized functions of intelligent high temperature, rain and fog prevention. The intelligent switching

In recent years, USB Type-C connectors have begun to appear in the market, triggering the upsurge of research and development of USB Type-C connectors. It is expected that more products will be on the market after 2016. The prominent advantage of Type-C is that it can be plugged in and out. It can also integrate

PLC is produced by using computer technology and combining the conventional control concept of relay. In one respect, PLC can be regarded as a computer system. Compared with general computers, it has special input and output interfaces to connect industrial processes. It has special programming voice to meet the control requirements. Because of its strong

Intelligent vehicle is an integrated system which integrates environmental awareness, planning and decision-making, multi-level driving assistance and other functions. This paper takes Freescale Cup National College Students Intelligent Vehicle Competition as the research background, using Freescale 32-bit microcontroller MK60DN512ZVLL10 as the core control unit. The system realizes the tracking motion of the intelligent car under
