VIRTUAL INSTRUMENT A foundation of the control system design is the concept of virtual instruments. In traditional observatory system design， instruments are typically considered entities whose design and components are fixed well in advance of actual use of the instrument. The approach works quite well when the role of the instrument is well understood with respect to the experiments it is to be used for. It also fits well with a system design where the instruments must be mounted on the telescope (e.g. mounting at the Cassegrain focus)， or exposed to the external environment - since the instrument is static， it can be more easily enclosed. However， this approach has some drawbacks in a laboratory style environment such as that provided by the ATST multiple-bench coude lab. In particular， providing the flexibility to explore new experiments results in a significant effort to adapt existing instruments to meet the requirements of the new experiment. The Virtual Instrument Model has been developed to address this issue， by abstracting the concept of an instrument from the specifics of the components used within that instrument. This allows the configuration of an instrument to be quickly adapted to meet the changes required by different experiments or changes to the laboratory environment. It should be noted that the virtual instrument is not a revolutionary concept but rather is the formalization of ideas often used in laboratory style experimentation. In the virtual instrument model， it is the experiment that drives the virtual instrument's 'design'. 4.1. EXPERIMENTS AND INSTRUMENTS Experiments are the heart of ATST operations and the control system is designed with this in mind. A laboratory style environment provides flexible support to carry out Experiments that are likely not understood or defined at the time the laboratory itself is designed. An Experiment undertaken at the ATST requires a Virtual Instrument. 不要機(jī)器翻譯的 要人工的 謝謝大家 展開(kāi)
