Software Development of Autosamplers for Gas Chromatograph Based on a Development Platform

Based on the concept of platform and modularity, two types of liquid autosamplers with different structures are developed and implemented in parallel. The principle of layering and modularity is adopted in the software design. Owing to the multiplexing and combination of various functional modules in the program, the working processes of two types of autosamplers are successfully carried out on the same development platform. The innovative design has not only resolved the compatibility problem of brushed DC motors and two-phase stepping motors and the driving problem of four-axis motors, but also proposes a fresh perspective and novel approach in the rapid development of autosampler products.
