基于ARM的农业装备共性参数测控系统
Measurement and control system for commonness parameters of agricultural equipment based on ARM
摘要
Abstract
Performance parameters characteristics of agricultural equipment were analyzed, and the measurement and control system for commonness parameter of agricultural equipment was developed based on ARM embedded technology, with the performance of measuring commonness parameter and testing comprehensive performance for agricultural equipment. The multithreading technology was used to meet the real-time data acquisition and control for various signals and the friendly interface application software was developed on the hardware platform which consists of S3C2410A and peripheral hardware circuits. This system could provide up to 34 channels. The results of measurement and field experiment showed that its analog channels linear error was 0.38% and the error of counting channel and frequency channel were all 1 Hz. The testing accuracy and reliability of this system was applicable to performance parameters measurement of agricultural equipment. This development can effectively enhance the method of measuring agricultural equipment's performance, and has high practicability.关键词
