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 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. The special power supply system that supplies power to the airborne experimental equipment at the experiment / work site provides reference signals. Based on the characteristics of the angular position indicator that can directly measure the vector angle and is light and easy to carry, it will pass the verification / calibration of the superior organization, and the accuracy level will be calibrated. The angular position indicator which is more than three times (or an order of magnitude) higher than the synchronous transmitter / resolver is used as a calibration standard device, and the output angle value of the calibrated device is directly measured at the experiment / work site, and the calculation error and uncertainty are completely and accurately calculated calibration data. This method enables field calibration of a synchronous transmitter / resolver.

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] Calibration of 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 power signal source (Valiable Signal Source), using a dedicated bridge (Resolver-SynchroBridge) and a digital multimeter or phase angle The 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 wi...
