Ship-borne Heavy Metal Elements In Seawater-site Automatic Analyzer Software Design

The trace heavy metal determination instrument is a kind of instrument which combines the method of using ISE and ISFET microsensors based on a sensitive chalcogenide glass with the method of the stripping voltammetry to determinate the trace metals in seawater. The software system investigated in this thesis is used to control the trace heavy metal determination instrument to run the test and analyze data ,The software system consists of several modules including data communication data preprocess pre-treatment respecting to real-time performance data storage, etc. The communication between the instrument and the server is based on serial port RS-232 or Ethernet Port and the communication among the modules in the software system is based on the message mechanism in Windows. According to the command that it received , the software system can control the running of our instrument, and use several methods such as digital filters curve fitting ,etc, to process the raw data and then store these results and transmit them to the server.The thesis mainly discussed several methods of data processing running tests parallel by using multiple threadso The details of the message mechanism used in our software system and the design of database are also discussed in this thesis.
