Transformer Terminal Design for Orderly Power Consumption Based-on the Embedded Linux

Aim at the orderly power consumption technology, develops an intelligent orderly power consumption management terminal, and builds a simulation environment. The hardware platform of transformer intelligent terminal is based on Atmel company"s Arm9 chip AT91SAM9260 as the core, uses embedded Linux operating system. The hardware configuration has USB, SDRAM, NAND, Flash, SIM card, 10/100 M Ethernet MAC, USART, SPI, display, electric energy acquisition circuit etc. Presents the transplantation of embedded operating system and the development of application program, transformer terminal software realized the multiple tasks control through the Linux multi thread mechanism, it is composed of the four parts of the bottom drive layer system layer protocol layer application layer, so it has good portability and scalability.
