[Abstract]:In recent years, with the rapid development and maturity of embedded technology, electronic technology and network communication technology, embedded data acquisition equipment with network communication function is informatization. With the development of network and intelligence, more and more people begin to live in daily life, which brings new industrial opportunities for traditional data acquisition and communication equipment. Under the background of the high level of network communication, this paper aims at the multi-parameter data collection and information release of ship lock, combined with the idea of "digital lock" in provincial waterway. This paper presents the design and implementation method of a data acquisition device based on Internet network, which is based on the embedded microprocessor ARM embedded operating system Linux. The network server and database are transplanted on this system platform. After the terminal system is connected to Ethernet, it can complete the functions of multi-parameter data acquisition, switch quantity control, remote access according to authority and service information release and so on. In order to realize these functions, a modern intelligent data acquisition and distribution platform model is established according to the problems existing in the traditional lock data collection and release mode. Based on the analysis of the functional characteristics of the embedded data acquisition and distribution platform, firstly, The hardware development platform based on S3C2440A controller chip based on ARM920T architecture and the software platform based on fully open source embedded Linux operating system are established. Secondly, based on the selected device hardware platform, The next step is to construct the software development platform of embedded Linux in the host environment, which mainly involves the analysis and design of U-Boot startup process of Linux system development platform. Transplanting the kernel of Linux system and transplanting the file system of yaffs 2 and the development of AD conversion driver. Thirdly, from the design of embedded web server, this paper introduces the working principle of embedded Web server Boa and its transplant implementation. The working principle and application of CGI, the characteristics of embedded database SQlite and its transplant application, etc. Finally, the data acquisition of terminal system is realized on the basis of embedded Boa server. The system web page of the data acquisition platform is established. With the DDNS technology of peanut shell, the IP fixed domain name of the embedded system is bound, the remote monitoring of the data acquisition platform is realized, and the access object can access the data and add the message separately. The feasibility of the design is verified. The embedded data acquisition platform system makes full use of modern information technology and network communication technology, which provides the support for realizing the key information digitization and improving the navigation efficiency and service quality of the lock system. It has some reference and popularization value for the construction of "digital lock" model.
