Abstract

The invention provides a detecting and evaluating system of a data acquisition unit. The detecting and evaluating system of the data acquisition unit comprises a physical condition detector of the data acquisition unit, the data acquisition unit, an optical branching device, a simulation merging unit and an electronic transformer state analysis and evaluation platform, wherein the physical condition detector of the data acquisition unit is in communication with the data acquisition unit and the optical branching device, and the data acquisition unit, the optical branching device, the simulation merging unit and the electronic transformer state analysis and evaluation platform are connected in sequence. The detecting and evaluating system of the data acquisition unit is capable of detecting and evaluating the electronic transformer data acquisition unit from all aspects and all angles under the conditions of electromagnetic interference, high-low temperature, temperature change, vibration, and the like.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a data collector detection and evaluation system. Background technique [0002] Data collector (Bar code Hand Terminal), also known as inventory machine, handheld computer.
