Datalogging Using Open Source?

trd79 asks: "I am responsible for setting up a system to monitor various parameters on a factory production line (mainly chemical flow rates and temperatures). I am currently using a datalogger from dataTaker and using their software (on a WinXP box) to graph the data in real time and download the data from the logger at the end of a shift. I would like to make the system more robust and reduce the need for user intervention. Does anyone know of open source data acquisition systems which are able to interface to popular datalogger brands? The ability to produce real time plots of the data during logging would be an advantage. Buying a new logger would not be a problem." "I don't really want to have to rely on the current XP system, as I don't believe it will survive being left on its own on the factory floor for long. Automation is key, as the line operators often forget to start/stop/download the logger. I would be interested to know if anyone have set up similar systems and if so, how well it worked."

MRTG? by jimmypw · 2005-11-12 23:31 · Score: 2, Interesting

I am not sure if this is entirely what you are looking for but MRTG is an open source SNMP monitor. It may work in your situation if the logger supports snmp. It can be a ittle tricky to use so recomend looking for configuration tools or the configuration file help on the MRTG website. On the plus side it will create 5 real-time graphs updated every x minutes for each variable you monitor, going all the way back to daily averages for the year. It works on windows xp and is easily migratable because it is written in PERL.

Enjoy and i hope it works
