Calibration device and method of magnetic flux sensor

Abstract

The invention provides a calibration device and method of a magnetic flux sensor. The calibration device comprises front and rear anchors, a magnetic flux sensor, a calibration rack, a through jack, astandard force sensor, a two-core data line, a reader, an eight-core data line, a magnetometer, an inhaul cable, a hydraulic gauge, an upper computer, an oil inlet pipeline, an oil return pipeline, an intelligent pump, a serial port line I, a serial port line II, a concentrator, a data line, and an address line. The magnetic flux sensor sleeves the inhaul cable; the through jack and the standardforce sensor sleeve the inhaul cable successively; the inhaul cable, the through jack and the standard force sensor are fixed on the calibration rack successively; the concentrator is connected to themagnetic flux sensor and is connected with the address line and the magnetometer by the data line; the magnetometer is connected with the upper computer; the standard force sensor is connected to thereader connected to the host computer; and the through jack is connected to the intelligent pump. A plurality of sensors can be calibrated simultaneously with high efficiency.

Description

technical field [0001] The invention belongs to the field of structural safety detection equipment, and in particular relates to a magnetic flux sensor calibration device and method. Background technique [0002] As one of the important means to measure the cable force of the bridge cable, the magnetic flux sensor has great significance in the accuracy and precision of the cable force measurement. The accuracy of the sensor calibration curve is the decisive factor for the accuracy of the measured cable force. [0003] The Chinese patent with the publication number CN103728059A discloses a magnetic flux control system for steel cable prestressing force values, including a magnetic flux impulse prestressing measuring instrument, a magnetic flux sensor, and a host computer. (1), the magnetic flux sensors are at least two , each magnetic flux sensor is connected to the hub respectively, and the magnetic flux sensor is switched by the hub to only connect one of the magnetic flux...
