描述

MTL831B

从零开始学电路基础- -“电路”
电路的概念- -电路是指由实际元器件构成的电流的通路。
电路的构成- -电路由电源、负载和中间环节组成。电源是可将其他形式的能量转换成电能、向电路提供电能的装置;负载是可将电能转换成其它形式的能量、在电路中接受电能的设备;中间环节是电源和负载之间不可缺少的连接、控制和保护部件统称为中间环节，如导线、开关及各种继电器等。
电路的功能- -电力系统中的电路可对电能进行传输、分配和转换;电子技术中的电路可对电信号进行传递、变换、储存和处理。
电路模型- -在电路分析中，为了方便于对实际电气装置的分析研究，通常在一定条件下需要对实际电路采用模型化处理，即用抽象的理想电路元件及其组合近似的代替实际的器件，从而构成了与实际电路相对应的电路模型。
理想电路元件- -理想电路元件是实际电路器件的理想化和近似，其电特性唯一、精确，可定量分析和计算。理想电路元件可分为有源和无源两大类，无源二端元件包括电阻元件(只具耗能的电特性)、电感元件(只具有存储磁能的电特性)。电容元件(只具有存储电能的电特性);有源二端元件包括理想电压源(输出电压恒定，输出电流由它和负载共同决定)、理想电流源(输出电流恒定，两端电压由它和负载共同决定)。
为了便于分析电路，应预先在电路图上标示出电压、电流的方向，电路图上的电压、电流方向称为参考方向，原则上可以任意假定。元件究竟是电源还是负载，应由元件上电压、电流的实际方向决定：实际方向关联时，元件是负载;实际方向非关联时，元件是电源。

主营：本特利，英维思，伍德沃德，福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐，ACSO，力士乐等各大品牌的DCS系统配件，机器人系统配件，大型伺服系统备件。

先介绍几点经验。
1、先通读一遍“系统手册”（不管能不能看懂，先了解个大概，以便学习编程时查找）；
2、由位控逻辑入手，逐渐增加定时、计数等条件，把或、与、非关系理顺；
3、进而练习整数运算、实数运算、类型转换；
4、量程转换、PID调节回路的建立及P、I、D参数的理解（最好是有个物理回路验证，比如变频器+电机+测速传感器）；
5、循环、顺序、跳转等程序控制（尽量避免跳转，非跳不可时也是跳的越近越好）；
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列，GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌，由于PLC的基本框架大同小异，学会一种至于其它的学习起来也就简单了。
