Research And Application Of Universal Detection Platform Based On ARM And Android

Recently,detection technology and equipment are widely used in industry,agriculture and so on.Be faced with the convenient market demand and complex high-performance competition,the system architecture is directly related to the success of entire testing equipment design.At present,most traditional platform or terminals using a technology project based on SCM and simple embedded microprocessor would cause insufficient collection and generality,inconvenient operation including access difficulties for different types of sensor,inadequate human-computer interaction,single function of information interchange and difficult integration for new functional modules because the testing equipment performance is radically restricted by this project.In view of this,following the generalization design concept,a new detection platform which comes in two parts,a detection terminal and a background server is developed using a solution of high performed soft and hard wares.Using the terminal of Exyons 4412 as the core processor can improve the detection platform processing capacity and enrich peripheral interface.Meanwhile,this platform chooses the popular Android4.4.4 operating system as on-demand terminal for high market share in favor of enhancing the convenience and generality of the detection platform,migrating and developing various sensor interface driver,realizing the corresponding HAL and JNI layer.Then,according to the specific requirements of applications,this thesis also configure the detection platform and carry out detection experiment,which the main contributions of it can be summarized as follows,1.The article mainly study a portable detection terminal based on ARM architecture and Android system.With Exynos 4412 as the core CPU,the terminal could configure with multiple network communication,data storage,and human-machine interaction modules.Also,this paper analyze the transplant process of Uboot,Linux kernel and Android system in detail with Android4.4.4 operating system as transplantation platform and develop the shared library of hardware sensor based on the technology of Android HAL and JNI.2.This dissertation build a generality and high-performance detection platform,which consists of two parts,a portable detection terminal and a background server.According to application requirements the detection terminal can configure with multiple sensors,and provide various data storage and transmit mode,and then the background server can store and process the transmission data by detection terminal.3.Besides,the thesis configure the detection platform as a multi-parameter soil inspection system,design the corresponding software of terminal and background server with the specific needs of application,and carry out performance and application test,which has gained good effects.
