Introduction This introduction is not part of IEEE Std 2402-2017, IEEE Standard Design Criteria of Complex Virtual Instruments for Ocean Observations. An oce
40、an observing system (OOS) plays an important role in improving the knowledge of oceans. An OOS involves software and hardware. The hardware part consists of various observing instruments; the software part consists of a series of applications that are responsible for data collection, data management
41、, and data visualization. Traditional developments are time-consuming due to code programming and testing while com- ponents usually need to be modified and assembled, which results in low development efficiency. Traditional virtual instruments display the observed data without considering the relat
42、ed metadata, such as the descriptive information of observed objects. A complex virtual instrument (CVI) is a software element having the following functions: It realizes unified management of observed objects and observed data. It connects with different acquisition applications and process measure
43、ments from one or multiple types of instruments. It provides data access interfaces which are designed based on observed objects. It can be extended and combined into a larger-scale CVI as a reusable software unit. This standard describes functions of the data management module, lists the requisite
44、functions in a CVI en- gine, and provides CVI interface design criteria for ocean observing. Following this standard, CVIs are ho- mogeneous and different types of CVIs can be composited into a larger system without code programming. This standard also describes the mapping schemes, which enables ea
45、sy mapping between CVIs and physical instruments. CVIs can be reused in different systems through adjusting the mapping schemes, contributing to higher-level software re-use. This standard plays an important role in improving development efficiency and standardizing development procedures for OOS software.
