描述

SVA603VAT-BCN/V

  数据经DTU发送到移动GPRS网络上的CGSN后,移动的GPRS网络与Internet有通道接口,因此,移动CGSN服务器可将数据经Internet再转发到数据中心服务器或者是路由器上。为了保证数据在移动网络到数据中心路由器之间传输的安全性,笔者使用了VPN功能。该功能在数据中心路由器和移动出口网关服务器之间建立VPN的GRE隧道,保证这两点之间数据传输的安全性,不被他人在中途进行信息窃取、修改。
    移动GPRS网络传输送来的各换热站数据经Internet,通过ADSLModem信号解调经防火墙检测后送达路由器VPN解密后,再将解密后的数据包转发到指定的数据中心服务器上进行数据接收处理,与此同时数据中心服务器担负着向各换热站发送相应控制指令数据的任务。各客户机从数据中心服务器上取得数据在各自的人机界面软件上完成对各换热站的监视控制、报警、历史曲线等功能。
    此外,在调度中心网络中,网关机与全厂MIS网络连接,负责把热网的各种运行参数送到MIS网上,供上一级相应MIS软件完成数据分析、数据挖掘等功能,大大提高热网运行的经济性。在这里,网关机与MIS网数据服务器的数据接口选用OPC,该接口使用方便、调试配置十分简单。

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。
