Real-time web based Timing display Application for Test Range Applications

Web based applications are availabel since long time serving many needs of the people such as e-marketing, e-governance, telemedicine etc. but real-time web application technologies are quite new. Nowadays real-time web application is highly demanded in many areas such as stock marketing, industrial plants, Test Ranges etc. where realtime data has to be visualised. The present work is an effort in the same direction wherein the Count Down Time information generated by a hardware device combined with synchronised actual time is displayed in real-time using a web application. For development of real-time web application server side java scripting using node.j s framework has been done. The paper presents detailed architecture of Websocket and its successor socket.io. The implementation of frontend using HTML, CSS and backend server using node.js framework has been done. Finally the time delay analysis from server to clients which are remotely located from each other in the Range has been shown. This paper compares the time delay in traditional standalone application and new web based application. In this way this real-time web application for Time display is first of its kind in Test Range.
