A Fault Diagnosis Capability Evaluation Test Simulation Device and System

Abstract

The invention is applicable to the technical field of measurement and control, and provides a fault diagnosis capability evaluation test simulation device and system. the device comprises a field display and control module, a measurement and control module and a signal conditioning module, wherein the field display and control module is used for sending a test instruction to the measurement and control module and displaying the test information sent by the measurement and control module; the measurement and control module is used for acquiring and processing excitation signals inputted after conditioning by the signal conditioning module according to the test instruction sent by the field display and control module, or, generating and outputting response signals to the signal conditioningmodule; and the signal conditioning module is used for isolating and conditioning the excitation signals inputted by the test device and the response signals outputted by the measurement and control module. Through the fault diagnosis capability evaluation test simulation device, enough simulation device interface signals can be provided for the test device, the number of samples for the fault diagnosis capability evaluation test is further ensured, and the errors of the evaluation model are reduced.

Description

technical field [0001] The invention belongs to the technical field of measurement and control, and in particular relates to a fault diagnosis ability evaluation test simulation device and system. Background technique [0002] In order to meet the requirements of equipment development and equipment fault diagnosis capability evaluation test verification, the simulation system development work was carried out. The fault diagnosis ability evaluation test evaluates the equipment fault diagnosis ability evaluation design level by obtaining the equipment fault detection rate, fault isolation rate and false alarm rate. [0003] In the process of fault diagnosis ability evaluation test, an important factor is the number of fault samples of equipment. Insufficient number of samples will lead to insufficient basic data for fault diagnosis ability evaluation test work, and the obtained evaluation model has large errors and other problems.
