Abstract

The invention aims to provide an automatic valve control system. With the automatic valve control system adopted, accurate state control and state monitoring can be performed on multiple valves of various chemical analysis instruments in a laboratory can be performed from a PC end and a mobile end application system; the valves can be accurately, timely and effectively controlled in a testing process; it is guaranteed that testing steps are accurately executed; and the full automation, high efficiency and accuracy of chemical analysis experiments are achieved. The system is characterized by comprising a valve, an electromagnetic valve, an execution setting module, a data transmission management module, a state monitoring module and an execution queue module.

Description

technical field [0001] The invention relates to the field of chemical analysis, in particular to an automatic valve control system. Background technique [0002] The detection of gas samples in industrial production and scientific research experiments often requires online, continuous, and regular cycle sampling analysis of gas chromatographs; if complex samples are analyzed, a multidimensional chromatographic system is also required (through valve switching technology, the sample is realized in multiple columns) separation). Manual operation is difficult to meet the requirements, and it is solved by adding a pneumatic or electric sampling valve to the chromatograph. Although imported and most domestic gas chromatographs provide valve control interfaces, most of them can only complete a single injection or valve switching through manual triggering. Continuous sampling and timing cycle sampling cannot be realized during manual operation. How to ensure the continuous sample...
