Title The research that Dynamic Measurement device of Turret Rotation Angle
Abstract
In order to improve the measurement accuracy of tank turret rotation angle, this paper proposed an dynamic-high-precision measurement system of turret rotation angle based on totary transformer.This system is composed of mechanical drive system and dual channel totary transformer.The system can achieve N×360°(N express cycle number)range dynamic-high-precision rotation angle measurement,and use serial RS-422 to communicate with PC, which could realize absolute-and-relative digital angle outputting .It also could position and orient instantaneously when powered on.
This paper introduced the background,purpose,significance and the development of angular measurement technology. Compareing various theories, a measurment system which constucted by mechanical transmission system and totary transformer was proposed. It analyzed the working principle of the angle measuring system and discussed classification and working principle of the totary transformer. The circuit board of the decoding whose core of the device is HTS20R and the circuit board of the optoelectronic positioning system whose key components is composed of launching board and receiving board was designed.This paper studied the dynamic characteristics of the system in the laboratory environment through the photoelectric autocollimator calibration platform, the results showed that the measuring real-time system was stable and reliable.The accuracy of measurment angular was 30〞. The tank turret has satisfied the integration of the stable sighting and the inertial navigation system required precision.
