Abstract

The invention provides a data acquisition and signal processing device capable of verifying various sensors. The data acquisition and signal processing device is used for realizing verification of a magnetoelectric speed sensor, a piezoelectric speed sensor, a piezoelectric acceleration sensor, an eddy current type displacement sensor, a linear differential transformer type sensor, a two-wire system vibration sensor and a magnetic resistance type rotating speed sensor. Another technical scheme of the invention is to provide a data acquisition and signal processing method capable of verifying various sensors. The data acquisition and signal processing device capable of verifying various sensors provided by the invention can realize data acquisition and signal processing for verification ofthe seven sensors.

Description

technical field [0001] The invention relates to a data acquisition and signal processing device capable of calibrating various sensors and a processing method using the device, belonging to the technical field of sensor calibrating and signal processing of steam turbine monitoring and protection instruments. Background technique [0002] The general description of the calibration and signal processing of the steam turbine monitoring and protection instrument (TSI instrument for short) is as follows: [0003] The steam turbine monitoring and protection instrument is one of the key protection devices to ensure the safe operation of the steam turbine. It mainly monitors the bearing vibration of the steam turbine unit, the relative vibration between the main shaft and the bearing, the axial displacement of the main shaft of the steam turbine, the speed of the main shaft of the steam turbine, zero speed, overspeed, and Key parameters such as the eccentricity of the main shaft of ...
