Introduction

The electronic data exchange at the construction site is rapidly becoming a key technology to promote industrial progress in the field of earthmoving machinery. From the manual number According to the collection method, it is converted to more automated data exchange and collection in order to improve workplace quality control. Electronic data exchange will enter Steps to assist in maintenance scheduling, strengthen the coordination of engineering tasks, construction management and daily operations on site, and provide for monitoring functions.

The implementation of an electronic data communication system requires the transmission of a data element that has already entered instructions and specifications. For use involving the use of application mode the unique data element specification for site communications should identify each of the data to be used. List of data elements compiled in data form in tabular form the code constitutes the part of GB/T 35484.

The purpose of building a data dictionary usually includes the following.

a) improve the ability to share data elements in a particular domain or between different domains;

b) Provides better semantic understanding and grammatical understanding of data elements;

c) Manage data resources in order to maintain correctness and consistency of resources;

d) Provides a basis for the consistency of data dictionary usage and the development of data dictionary software.

Earth-moving machinery and mobile road construction machinery Site data exchange - Part 2. Data dictionary

1 Scope

This part of GB/T 35484 specifies the data exchange data in the field data control construction work defined in GB/T 35484.1.

dictionary.

This section applies to site data exchanges for the purpose of services related to machinery (see Chapter 4 of GB/T 35484.1-2017).

Change, and give the definition of terms related to site data exchange.

The data exchange between different systems includes.

--- The identification, definition and specification exchange of general data items on a typical earth-moving construction site;

--- Definition of application block diagram;

--- Metadata describes the attributes of each data element;

--- Basic specification and its attribute data element (table form).

Note. Appendix A of GB/T 35484.1 describes the method of extending the data element table.
