智能超重机超载限制器设计

Intelligent Overloading Limiter of a Crane

本文根据起重超载限制器的控制需求,以实现监控、维护、管理一体化为目标进行了设计。起重超载限制器以AVR高速单片机为核心,应用信号调理技术对传感器输出电压进行去高频噪声、放大、二阶有源滤波处理,应用微机接口技术设计了液晶显示、触摸屏、语音、实时时钟、串行E2PROM、U盘读写模块、串口通信、AD转换等接口模块电路,应用电子技术设计了电源、掉电检测,延时等电路,并使控制系统具有较好的抗干扰能力。

This paper presents the design of an overloading limiter. The overloading limiter uses the AVR high speed monolithic integrated circuit as the core, applies the signal process technology to wipe off the high frequency noise. The desin of the hardware and software of the system is outlined in detail.
