Application Research On Network Technology In Embedded Industrial Instrumentation

With the increasing complexity of industrial site conditions, control instrumentsin the industrial field and on-site monitoring of the state-level requirements are alsoincreasing. On the other hand, to achieve remote real-time monitoring has becomepossible and is developing as a new technology in today’s highly developed Webtechnology.Network Remote Monitoring System based on B/S model has begun toappear momentum of replacing traditional C/S mode monitoring system. Applicationof new technologies in the industrial instrument to meet the remote monitoringsystem has become increasingly high demands of the current industrial hot researchfield.This paper studies the B/S design mode in remote communication and proposesthe ‘Apache+HTML5+PHP+C’’s overall framework. This paper designs andimplements the C program for the embedded industrial instrumentation as Serverside and the HTML5program for browser. The use of Websocket in HTML5specification API helps the server and browser to implement remote communicationand the browser achieves dynamic data display with the use of Canvas API. With thehelp of PHP，the paper for embedded industrial loggers in the configuration file, andmodify the database file downloads and other features. Based on the needs ofindustrial system remote monitoring system, this article also analyzes the relativeadvantages of various Websocket agreement interactive mode against the traditionalWeb.With respect to achieve industrial instrumentation embedded remote monitoringin the traditional way, using HTML5technology improves the poor real-timecommunication and overcomes the software platform common defects. To implementthe Websocket communication protocols in the embedded Linux operating systemdirectly does not rely on complex server migration ways. This pattern of industrialinstrumentation to achieve remote monitoring system is ideal for limited MCU resources, real-time requirements and the requirements of the situation quickly buildsystems.The success of this study used in embedded industrial loggers achieves the goalof real-time communication in industrial field data, the data show，the database filedownloads and modifies the instrument configuration files and other functions.Accordding to the actual test we may know that this article is designed based on B/Smode of Apache+HTML5+PHP+C design architecture running on an embeddedindustrial instrumentation in stable and good real-time and achieves the desireddesign goals.
