Abstract

The invention provides a control method and system of a dual-channel rotary transformer type inductance shaft angle encoder, which can monitor the output voltage state of an excitation power supply corresponding to a dual-channel rotary transformer of the shaft angle encoder and accurately adjust the power supply output of the excitation power supply. Therefore, the shaft angle encoder can be ensured to carry out accurate coding metering work. Besides, thermal infrared detection is carried out on the interior of the shaft angle encoder, so that the temperature state in the shaft angle encoder is determined, the shaft angle encoder is cooled in time, and stable and continuous work of the shaft angle encoder can be maintained to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of encoder control, in particular to a control method and system for a dual-channel resolver-type inductive shaft-angle encoder. Background technique [0002] The shaft encoder is mainly used for real-time accurate measurement of the azimuth / pitch angle position of the radar antenna. The existing dual-channel resolver-type inductive shaft encoder uses the excitation power supply as the excitation signal source, which is used to excite the shaft-angle encoder for corresponding encoding and measurement, so the voltage output by the excitation power supply directly affects the output voltage of the shaft-angle encoder. Accuracy of encoding results. In addition, the layout of the internal circuit components of the shaft encoder is complicated, and heat will be generated during the working process. If the heat cannot be dissipated in time, the normal operation of the shaft encoder will be seriously affected. It...
