Recording and Valuation of Gas Concentrations

Task

Development of a micro controller system for recording, analysis and display of gas concentrations from several measurement stations, distributed over a wide area.

Requirements

  • Observation of the actual measurement values on each channel for given top and bottom limits
  • An independent designed alarm administration (self-maintaining; self-erasing etc.) for each channel
  • Free configurable printout of the alarm events via a directly connected printer
  • Visualisation on a graphical LCD display
  • Configuration of the whole system via an optional connected PC
Board (w/o Housing)

Solution

Development of a specific serial bus system for sensor connection by our partner company TIGRIS Elektronik GmbH. Interrupt-driven micro controller programming of an 8051 derivate in C. Menu controlled LCD display with five buttons and two key switches. Optional connection of a PC via RS232. Design of a configuration program with LabWindows/CVI (National Instruments).
