Design And Implementation Of Embedded Data Acquisition And Release Terminal System Of Shiplock Based With ARM

In recent years, with the rapid development and maturity of embedded technology,electronics technology, as well as the network communication technology, the dataacquisition equipments with the function of network communication have beenincreasingly entering people’s daily life during the Informationalized, networked andintelligent times. It brings new business opportunities for traditional data collectionand communication equipments.Aiming at multiparameter data collection and information dissemination of tailgate and combining the idea of “digital shiplock” raised by Waterway Bureau ofJiangsu Province, this topic proposes an data acquisition equipments’ designphilosophy and implementation methods based on Internet network for datainteraction under the context of high levels developed of network communication.This system uses embedded microprocessors ARM and embedded operating systemLinux as its core ideology, and on the system platform network servers and databasesare transplanted. After the terminal systems access to Ethernet, the system can realizesfunctions, such as multi-parameter data acquisition, switch control, remote access andservice information distributed.In order to achieve these functions, Firstly, this paper studies the weaknesses oftraditional data collection and distribution, establishes modern intelligence collectionand distributing platform model, adopts S3C2440A which based on ARM920T to bethe core hardware development platform and establishes embedded Linux system asthe main software platform on the basis of analyzing functional characteristics ofembedded data collection and distribution. Secondly, on the selected hardwareplatform, the article builds an embedded Linux software development platform stepby step based on Host situation, which contains the building of Linux system platform,analysis, design and transplantation of U-Boot boot process, customization andtransplantation of Linux kernel, production of Yaffs2root file system, anddevelopment of the AD device driver. Then, starting from the design of embeddedWeb server, the thesis analyzes the key technologies in depth which contains theworking principle, application and transplants implementation methods of embeddedWeb server Boa, dynamic Web CGI technology and embedded SQLite database.Finally, on the basis of embedded Boa server, this thesis implements data collection on terminal data acquisition system and establishes the web pages which are used fordata collection. It binds its fixed IP’s domain name and achieves the goal of remotemonitoring with the DDNS technology. The interviewers can access data and addmessages depending on their limits of power, which verifies the feasibility of thedesign.The embedded data acquisition system takes full advantage of moderninformation technology and network communication technology, provides supportsfor the realization of “digital shiplock” and improvement of navigation efficiency andquality of service. It has significant value of building the model of “digital shiplock”.
