Universal Optoelectronic Measuring Modules in Advanced Distributed Measuring Systems

摘要

Large or long objects require measuring systems as a combination of more than one measuring instrument. In this case, the combination of instruments is a network system consists of several measuring modules and one central module. Measuring modules make the preliminary computation of measuring information and translate it to the central module for the final computation of measuring parameters. The central module also makes statistics of measuring and archive of information. Some tasks require the noncontact methods of measuring angular and linear coordinates of objects or places. The Central module can perform two-stage processing of measurement information. In the first stage, the Central measuring module performs a preliminary configuration of the distributed measuring system based on the information received from GPS sensors. The second stage is to use the measuring information received from the peripheral modules based on optical-electronic measurement methods. Using two-stage processing can significantly improve the efficiency of a distributed measurement system. The optoelectronic measuring devices (OEMD) are ideal for these purposes. These devices also have other advantages like great precision, calibration, and adaptation. In this article variants of the distributed measuring systems are described. The basic attention is given to the description of the unified optoelectronic modules for the measurement of angular and linear coordinates.
