Abstract
With the development of electronic information technology, household appliances and industrial field need more and more Vacuum Fluorescence Display (VFD).The VFD examination rate limits the output increases In order to solve this problem, the article proposes a design of examination system bases on Omron PLC.
This system takes Omron PLC as a controller to designs the examination system of VFD. This article has introduced the VFD examination system's software and the hardware architecture design, VFD examination system's working procedure. The concrete implementation's hardware circuit diagram as well as the software flow diagram particularly and given back the course and steps concretely according to the VFD examination system's performance index. This topic research has carried on massive debuggings to prove that the system satisfies to the technological requirement of enterprise. This article research content has reference value and guiding sense to other similar research of examination system and important meaning to enhances the grade of automatic of VFD examination facility.
