Abstract

The present application belongs to the technical field of metrological calibration, and particularly relates to a logging instrument data acquisition signal calibration system, method and device, aiming to solve the problem of high degree of manual intervention, complicated operation, low intelligence and time-consuming and laborious of the existing detection signal calibration method. The present application comprises: real-time acquisition of logging instrument measurement signals; based on the measurement signals, calculation of the relative error of the measurement signals and the standard reference signals, when the relative error is greater than the preset error acceptance threshold, setting the data acquisition signal as an abnormal signal; based on the abnormal signal, searching for the equipment abnormal area, and performing equipment maintenance on the equipment abnormal area until the relative error is less than the preset error threshold, and the logging instrument normally acquires signals. The present application can obtain the output of the calibration signal and the output of the measurement signal in real time, can perform factory calibration and periodic calibration of the logging instrument, provide the accuracy of the instrument, and has traceability and transferability.
