| 摘 要: 针对现有针织圆机[1]加油装置无法精准控制和计算喷油量，基于ARM平台设计了一种精准高效的针织圆机喷油系统。系统实现的功能包括信号采集、信号处理、人机交互和控制输出。针对机械振动导致的油位波动问题，通过最小二乘法[2]求出两个小时内油位数据的拟合曲线，得到当前油位的预估值。人机交互[3]设计包括油耗显示、气压显示、报警输出、系统参数录入等。通过测试对比，系统能够精确控制喷油时间，准确显示油耗信息，及时对异常情况报警，具有较高的准确性和稳定性。 |

| Abstract: Aiming at the inaccurate control and calculation of fuel injection volume of the existing circular knitting machine[1] refueling device, this paper proposes to design a precise and efficient circular knitting machine oil injection system based on ARM (Advanced RISC Machine) platform. Functions of the system include signal acquisition, signal processing, human-computer interaction and control output. With regard to the problem of oil level fluctuation caused by mechanical vibration, the fitting curve of oil level data within two hours is obtained by using the least square method[2], and thus the estimated value of the current oil level is obtained. Human-computer interaction[3] design includes fuel consumption display, air pressure display, alarm output, system parameter input and so on. Through comparison test, the proposed system can accurately control fuel injection time, precisely display fuel consumption information, and timely alarm for abnormal situations. The system has high accuracy and stability. |
