The invention provides a data acquisition system for digital display measures. The data acquisition system comprises the different digital display measures, acquirers corresponding to the digital display measures one to one and an upper computer. A movable measure set establishing module and a movable measure set maintaining module which are operated on the upper computer keep movable measure items contained in a movable measure set module identical to the digital display measures and the acquirers of the upper computer. According to a matching result sent by a measure identification module, a measuring result obtaining module sends a measuring result obtaining command to the matched acquirer and receives the measuring result.
Description
technical field [0001] The invention relates to a data acquisition system for a digital display measuring tool, which belongs to the technical field of measurement and testing. Background technique [0002] At present, digital design and manufacturing technology has been greatly developed, and traditional detection technology has increasingly become a bottleneck restricting the improvement of production efficiency and production quality. At the same time, as a key missing link in the digital closed-loop manufacturing system, digital detection technology has been more and more scientific attention of research institutions. [0003] The automatic data acquisition of general measuring tools is a key issue in the implementation of digital inspection technology. In order to meet a wide range of social needs, major measuring instrument manufacturers have launched digital display measuring tools and measuring instruments with digital display and output functions. However, digital ...
