Problems solved by technology

Although the above method has high calibration accuracy, it has relatively high requirements on the calibration environment and standards. It is generally only suitable for synchronization / analysis equipment with high calibration accuracy in the calibration laboratory environment, and cannot be implemented in the work or experiment site. Calibration needs
At present, the synchronous transmitter / resolver commonly used in experiments / work is generally embedded in large-scale experimental equipment, and its calibration accuracy is not high, and it is difficult to disassemble and send to the calibration laboratory, so the above method cannot be used for calibration

Abstract

The invention relates to an onsite calibration method for a synchro transmitter or analyzer, and particularly aims to meet the calibration requirement of the synchro transmitter or analyzer which is difficult to detach from large-scale equipment. The field calibration method comprises the following steps: adopting a special power system used for supplying power to onboard experimental equipment on an experiment or work site to provide a reference signal; based on the characteristics that an angular position indicator can be used for directly measuring a vector angle and is portable, taking the angular position indicator, which is certificated or calibrated by a supervising authority, and has an accuracy class three times or higher than (or has the same magnitude order as) the synchro transmitter or analyzer to be calibrated, as standard equipment for calibration, directly measuring an output angle value of the synchro transmitter or analyzer to be calibrated on the experiment or work site, and calculating an error and uncertainty to obtain complete and accurate calibration data. Through the adoption of the onsite calibration method, the synchro transmitter or analyzer can be calibrated on site.

Description

technical field [0001] The invention relates to a method for realizing on-site calibration of a synchronous transmitter / resolver, and is especially suitable for the calibration requirement of a synchronous transmitter / resolver that is difficult to disassemble on large equipment. Background technique [0002] To calibrate synchronous transmitter / resolver and other types of equipment, the general application method is to give a reference signal through a variable frequency power supply or a power signal source (Valiable Signal Source), use a special bridge (Resolver-Synchro Bridge) and a digital multimeter or phase Phase Angle Voltmeter (Phase Angle Voltmeter) calibrates the measurement error of the voltage or angle value output by the synchronous transmitter / resolver. Although the above method has high calibration accuracy, it has relatively high requirements on the calibration environment and standards. It is generally only suitable for synchronization / analysis equipment wit...
