摘要
设计了一种基于嵌入式微处理器的连铸结晶器非正弦振动控制器,用整体函数法构造非正弦曲线。硬件设计包括:同步串行接口(SSI)模块、模拟信号输入模块、CAN模块、模拟控制信号输出模块等;其中SSI信号的应用可有效提高振动位移信号采集的精度、速度和抗干扰能力。软件设计提出了一种对非正弦参数进行分步修改的程序设计方法,避免实际生产中在线修改振动参数对系统造成的冲击。该控制器带有CAN总线接口,可独立工作,也可作为智能CAN节点用于构建基于CAN总线的多流连铸机振动控制系统。
A non-sinusoidal oscillation controller for Continuous casting mould was designed based on STM32, and the non-sinusoidal curve was constructed by entire function method. The hardware designs include： SSI module （synchronous serial interface）, analog signal input module, CAN module, control signal output module etc. Among them, the application of SSI improves accuracy, velocity and anti-interference ability of oscillation displacement signal acquisition. The software functions include judgment and stepwise modification of non-sinusoidal parameters, data acquisition, PID operation and so on. The controller has CAN bus interface and can work independently and can also be used as intelligent CAN node which can be used in constructing multithread continuous casting mould control system based on CAN bus.
