Design And Implementation Of The Of Tensile Test Machine Controller With Cortex-A8

The Tensile Test Machine Controller is the key part of the Tensile Test Machine,which is used to test properties of materials. Recently, Tensile Test Machine controller isconstantly upgrading as more requirements of materials test and the increasing standardsof the test. It is difficult for the traditional control systems to synchronize hardware andsoftware design, and more difficult for separating software work to several parts, whichleading to long development cycle, low efficiency and the improper use for the design.Therefore, to address this problem, this thesis presents a new high-performance TensileTest Machine Controller which is based on embedded software and hardware design.In this Thesis, the function and performance requirements of the Controller are putforward by much market survey for all kinds of Tensile Test Machine Controllers. Thisthesis certainly adopts the overall plan centered on Cortex-A8Series processor andEmbedded Linux operating system (OS) to design the Controllers. Based on that plan, theoverall designs and the system scheme of the Controller are proposed and the designs aredivided into PC software, hardware, Embedded Linux OS platform and applicationsoftware design,all of which are described in detail. Embedded Linux OS platform isconstructed based on the hardware and function requirements, as well as device driverdesign and kernel configuration. Then, the application of uploading and downloadingmodule, storage mapping module, system functional modules, LCD display module anduser input module are designed and realized.Through the performance tests of the platform and program, some results are obtained.By analyzing those results, it shows that the Tensile Testing Machine Controller systemhas the high performance of stability and real-time which proving the feasibility of thescheme in this thesis. Finally, the work of the design is summarized and how the TensileTesting Machine will develop is presented.
