How to display realtime meter reading data from TCP or serial on web
Posted on 2010-09-22
I may need to display realtime meter reading values on the web site. The data will be received by the server through TCP or serial port.
I plan to make one program A on server to receive the realtime data and pass them to web server, and save to DB also. But I am not sure how to let the program A pass the data to the web server, or through whcih way.
When the end user start a web page, all and only the meters in this page need refresh the realtime display. The web server need to pass this meters ID to program A, and A start to polling these meters realtime value with faster speed. Can this be done in the web server.
