Introduction

In recent years, the industry has realized that the measuring device converts data from one form into another form will spend a lot of time and energy. For example, an instrument of technical data, the manufacturer will exist in paper and electronic documents two separate data sets, and eventually Users require product specifications, engineering database or data are consistent with commercial databases. However, since the devices have different uses for each respective Since the data storage format, so in most cases, the data can not be shared.

Technical data sharing and contradict the second problem lies in the product description itself. To express specific performance test results, for example, Technical data sheet should contain information on what should be how to organize, how to express, or ultimate, manufacturers rarely reach a consensus. That most End user the relevant information into the database, the data is always found inconsistencies or different meanings, making it difficult to establish a database.

This section aims to define a common measurement and control equipment structure and its contents to solve the problem of industrial processes. This is based on the following Conception. Press measuring device type (for example, pressure measuring devices, temperature measuring equipment or electromagnetic flow meter device) provides a common structure and product A collection of properties. The final document is not limited to the electronic exchange, and easy for users to read and understand.

This section applies to the electronic catalog processes with analogue and digital outputs of the measuring device. The future will continue to develop similar classification structure Applicable to the process with binary output and the rest of the interface device measuring equipment. This section describes the structure has been included with the binary input the measuring equipment most commonly used product features. Appendix B also take into account the future standardization.

This section relates to all hope for future process measurement device documentation standardized criteria to develop guidance documents. Each revision in the future now Bank standards, the structure and characteristics of the product in Chapter 5 of this section defined, are advised to adopt or try to reach consensus.

Appendix A contains a measuring device classification process list and directory structure. Appendix B contains a specific measured variables are further subdivided

Sub-classification.

This structure as much as possible the use of existing international standard terminology to name the product characteristics. ISO 10241-1 according to the provisions of this Part Chapter 3 lists the terms and definitions and references.

Creating a structured document in accordance with the standard. With the Standard Generalized Markup Language (SGML) GB/T 14814 described in or derived from SGML Extensible Markup Language (XML) can give an appropriate way to the need to export structured information exchange.

This section also provides (data element types) classification basis in line with GB/T 17564 or GB/T 17645 properties. This section requires Terms of the feature with text, graphics and tables showing further decomposed into attributes (data element types) conforms to the standards. For example, the Expressed as a range with a lower limit of units of measure (LRL --- lowerrange-limit) and an upper limit (URL --- upperrange-limit), the foot Inches respectively length × width × height (L × B × H) 3 elements with the unit of measure used to label, or decrease power curve as a series of correspondence Coordinate data.

This section relates to reference standards GB data integrated data model and relational database of reference/T 18975.1, GB/T 18975.2 and ISO 15926-4, for example, using a restrictive classification structure. At the same time, this section also exchange standard (STEP-Ex- and Product Model Data changeofProductModelData) consistent. ISO 10303-21 data model and defined by reference to the number of ISO 15926-4TS According to the library as a "database." According to this section, the current standard can reproduce data including product structure, the size of data, data and electrical connections Product performance data fields in the measuring range or power, etc.,.
