Signal conditioning equipment

Abstract

The invention discloses signal conditioning equipment which comprises a control computer, a master controller module connected with the control computer, and at least two conditioning modules, wherein the interiors of the conditioning modules correspond to conditioning board cards of different signal conditioning types; the master controller module and the conditioning modules are arranged on a back plane; a control bus is arranged on the back plane; the master controller module is connected with the at least two conditioning modules through the control bus; the control computer receives a conditioning instruction sent by the user, and sends the conditioning instruction to the master controller module, then the master controller module receives and analyses the conditioning instruction and sends the conditioning instruction to the pre-configured conditioning module corresponding to the conditioning instruction, and finally the conditioning module receives the conditioning instruction and conducts corresponding signal conditioning. According to the signal conditioning equipment, the computer conducts real-time mode switch and parameter setting on the signal conditioning board card according to actual requirements, and the dynamic signal conditioning function in case of no equipment outages is realized.

Description

technical field [0001] The invention relates to the fields of data acquisition and semi-physical simulation testing, in particular to a signal conditioning device. Background technique [0002] The existing signal conditioning equipment plays a bridge role in the application of data acquisition and semi-physical simulation. It is not only responsible for converting the signal of the device under test into a signal acceptable to the acquisition end, but also conditioning the excitation signal sent by the acquisition end. into a signal acceptable to the device under test. In practical applications, at least two types of physical signals need to be conditioned, and different conditioning circuits need to be used for different signals. At the same time, since the electrical isolation of these signals is unidirectional, the isolation circuit will be different according to the direction of the input signal. [0003] Most of the existing signal conditioning equipment adopts the f...
