The Application Of Embedded Linux In ATSE Based On ARM Processor

Automatic transfer switching equipment (ATSE) as an important electrical equipmentwhich used to ensure the power supply reliability is widely used in essential supply lines.With the development of smart grid,there are more intelligent equipment used in grid that isbecoming an inevitable tendency. In order to satisfied the smart grid’s requirement,thisresearch aim at designing a new ATSE controller.This paper mainly demonstrate a new designing method of ATSE controller bycombining ARM processor with embedded Linux operating system.We implemented thecontrol system function by designing of hardware and software of ATSE system. Thespecific designing work include the following two aspects:1、The minimum control system is based on S3C2440with ARM9as the core inhardware designing.The design of function circuits such as LCD display circuit、parameteracquisition circuit、executive circuit and failed warning circuit is completed based on thisminimum system.2、In this paper the design of software use embedded linux system as the softwaresupport platform.By developing of application program on operating system level,werealized ATSE system control function.The specific design work include:seting updevelopment environment、 programming devices’driver and designing of applicationprogram based on QT CREATOR.In the end of paper,there are some simple introduce ofdigital filtering theory and software anti-jamming technique.This paper introduce the designing method of ATSE which use embedded operatingsystem as the control system.The using of embedded Linux OS make it convenient todevelop the ATSE software system.The addition and modification of system function ismore easier based on Linux OS.
