The Design Of Vehicle Charging Spot Based On Embedded System

The current world energy and environmental issues has become one of the major problems that restrict the development of human society, the shortage of petroleum resources, global warming has become a common problem faced by all countries. Car as one of the main transport current of humanity, consume a lot of oil, while large amounts of carbon dioxide emissions and other emissions. With economic development, the popularity of cars the in creasingly serious senvironm ental problems, more environmentally friendly new energy vehicles gradually into people's vision, began research into electric vehicles more and more countries and regions. Charging spot is the electric vehicle industry are essential. The development of electric vehicles must be based on the popularity of related charging facilities on the basis of, including charging spots, charging stations, battery equipment, maintenance and billing monitoring and so on. Charging facilities and the development of universal access to the development of the electric vehicle industry is the prerequisite and basis, in particular, convenient and fast exchange of charge spot, you can anywhere to provide charging services for electric vehicles. The development of electric vehicles and supporting the development of charging facilities are complementary and indispensable.This paper focuses on electric vehicle charging spot design study. First, the research status of charging spot in the field of development and related fields at home and abroad were preliminary introduction, starting from the needs analysis and the main charge spot control technology, charging spot for the overall system design, embedded system is S3C44B0 X main control system, were carried out the interface circuit design of the power, reset circuit, Flash, Ethernet, configure LCD touch screen, easy human-computer interaction, by charging spot pilot circuit control and charging circuit for charging spot interrupt charging control. Embedded operating system ?C / OS-?as a platform, it details the ?C/OS-?operating system migration and implement display Chinese, combined with the actual needs of charging poles for electric vehicle charging spot extends the charging and metering IC card reader functional, user-friendly usage and billing.
