摘　　要：针对插剥式椰子剥衣机自动化程度低的问题,基于MC9S12XS128单片机设计了椰子剥衣机的电气控制系统。该电气系统包括硬件电路和软件程序两个方面,给出了主控板电路、电源电路等部分的设计方案。在此基础上,结合剥衣机的流程给出软件程序。以MC9S12XS128单片机为核心,通过对其内部电位的控制,完成对步进电机的启停、速度、转向及运行时间的控制,最终自动完成椰子剥衣的整个过程。实验证明,该电气系统运行平稳,剥衣效果良好。该方案设计合理,自动化程度高,可以在实际生产中推广应用。According to the problem of low - degree automation for coconut husking machine at present,the electrical auto - control system of coconut husking machine was designed based on MC9S12XS128single - chip microcomputer. The electrical system included hardware circuit and software procedure, andthe design scheme of part circuits were given, including main board circuit, power source circuit, etc.On the basis, the software procedure was given by the flow - chart of coconut husking machine operation.With MC9S12XS128 single -chip microcomputer as the core, the controls of start and stop, speed, rota-tion direction and operation time for stepper motors were achieved by controlling the interior electric po-tential of single - chip microcomputer, then the entire process of coconut husking was finished automati-cally. The experiment presented that the electrical control -system operated smoothly and steadily, andthe husking effect was good. The design scheme was reasonable with high automation, and could be pop-ularized and applied in practical production.
