Measurement system using double CPU modules for human machine interface control and measurement module control

摘要

A measurement system analyzes and displays measurement data obtained from measurement modules with respect to prescribed measured values. A large scale graphical user interface (GUI) is provided as a human-machine interface and functions as a display as well as a data input device. The measurement system employs double CPU modules for sharing loads of data processing required for the GUI and measurement modules, respectively. A first CPU module controls the human-machine interface and performs data processing. A second CPU module controls the measurement modules. The first CPU module uses a firsts system for communications, whereas the second CPU module uses a second bus system for communications with the measurement modules. A bus exchanger connects the first and second bus systems so that a user of the system can control the measurement system using the GUI while providing real- time performance for the measurement modules.
