1、 I 基于单片机的鱼用投饵机自动控制系统的设计基于单片机的鱼用投饵机自动控制系统的设计 摘摘 要要 单片机又被称为单片微控控制器,单片机(Microcontrolles)其实是一种 集成电路芯片,它可以算一个小而完善的微型计算机系统,它把 CPU、RAM、ROM、 多种 I/O 口和中断系统、定时器/计数器等功能集成到一块硅片上,单片机在工 业控制领域广泛应用。它相当于一个微型计算机,与计算机相比它只是缺少一个 I/O 口而已,单片机具有以下几个方面的优点: (1)系统结构简单,使用方便, 实现模块化; (2)它的可靠性高,即使工作到 106107 小时也不会产生故障; (3)处理功能强,速度
2、快; (4)电压低,功率低,便于生产便携式产品(5)控 制功能强; (6)环境适应能力强。单片机在以下几个方面被广泛运用:如智能仪 表、实时工控,通讯设备,导航系统,家用电器等。各种产品一旦用上了单片机, 就能使产品产生质的飞跃, 一般的投饵机控制系统存在着定时不准确、 可靠性差、 投饵与间歇时间设置不合理、不能合理调节投饵距离、浪费饲料等问题。为了解 决此类问题,本论文研究了基于单片机的鱼用投饵机自动控制系统,该系统设定 参数为供饵时间、停饵时间、投饵时间和投饵距离,控制对象为输送减速交流电 机和投饵直流电机;同时,从硬件和软件方面介绍了本自动控制系统的设计和制 作。实验结果表明,该系统能够

The single-chip microcomputer is widely used in industrial control field. It is equivalent to a microcomputer. Compared with
5、 the computer, it just lacks of an I/O pot. The advantages of the single-chip microcomputer has the following several aspects: (1) The system structure is simple, easy to use, and implement modularity (2) Its high reliability can ensure that it will not breakdown even works 106 to 107 hours (3) Powe
6、rful processing capabilities and fast speed (4) Low voltage and power, to facilitate the production of portable products (5) Powerful control function (6) Powerful environment adaptability. SCM is widely used in the following fields: for instance, intelligent instruments, real-time industrial controls, communications equipment, navigation systems, household appliances and so on. Once all kinds of products use the single-chip microcomputer, they will produce qualitative leap. General bait c
