Nonlinear Error Compensation and Anti-jamming Technique of Digital Clinometer
Lei Shi · Yibiao jishu yu chuanganqi · 2013
Aimed at the requirement that the clinometer for a elevated platform should have high-precision,long data-transmitting distance and anti-jamming capability,the sensor features,hardware connection and data acquisition of the serial output accustar clinometer were introduced.Nonlinear error was calibrated through experiments and compensated by software,and isolating drive circuit was designed for long-distance data transmission.In practical application,the nonlinear error decreases from 0.9% to 0.1% after compensation and the platform can meet the requirement for positioning accuracy of ±0.05° in bad EMI environment.
