Title The hardware design of intelligent controller based on WiFi
Abstract
In recent years, with the development of society and the improvement of science and technology, wireless communication technology updates constantly. Governments around the world have paid much attention to it. The hot spot for the application of wireless communication technology is WLAN( Wireless Local Area Networks). WLAN is a combination of computer network and wireless communication technology. And it can serve as traditional wired LANs. As this technology becoming increasingly mature, fields which it can be applied to expand as well.
Basing on the technology of WiFi, this paper designs an intelligence controllor as the high-end car central control system, which utilize devices including SCM( Single Chip Microcomputer), optical coupler, switching power supply, and level conversion element. Using carry-on mobile phones or PAD with Android or OS system, it is possible for subscribers to control vehicle equipment remotely such as the air-conditioned, doors, windows and seats. This will bring a distinctive wireless communication experience to them. This paper proposes the hardware structure and designs the circuit part of the intelligence vehicle controllor.
