基于ARM7TDMI的羽绒充灌设备控制系统设计

充绒机是将羽绒按照要求的重量精确地从容器充灌到被服中的一种具有自动化、智能化的机械电气设备。对自动变频充绒机的工作原理、充绒过程控制系统实现、基于模糊算法的充绒机控制策略的自动控制系统的实现、变频调速技术的应用、串口通信反馈实现闭环控制等方面进行了具体而深入的研究,在此基础上完成了基于ARM7TDMI核的系统硬件设计。实践证明:系统硬件运行稳定,在进行模糊推理学习时具有更快的速度。

Control system design of automatic down-filling machine based on ARM7TDMI

The Down-filling machine is an automatic, intelligent, mechanical and electrical device with low-cost, convenient, great efficiency that can reduce labor intensity and improve labor conditions. It can fill down to duvet or down jacket from the container according to weight data exactly. This paper elaborated on several aspects: working principle of automatic Down filling machine, realization of control system, realization of control strategy based on fuzzy inference, and research of serial communication feedback. The hardware system of Down-filling machine based on ARM7TDMI has been finished. And the system makes software and hardware logical in system frame, and achieves high complex controlling with low cost. In control field, closed-loop control is also implemented in this system. At the same time, the function modules of industry Down filling machine has been studied, such as man-machine interface, motor control, the use of the FLASH memory AT29C020, the use of weighing sensor, etc. Results show that the system hardware has high stability and fast speed in fuzzy inference.
