工业自动化现场的数据采集系统 PDA

这里要说的 PDA,不是Personal Digital Assistant (个人数码助理)的缩写,而是Process Data Acquisition的缩写,顾名思义,是“过程数据采集”的意思。

The “PDA” is the meaning of “Process Data Acquisition”. rather than the meaning of “Personal Digital Assistant”.

在步入正题之前,先关注网友@CSK_的一个小项目:太阳能气象站 http://www.yeelink.net/devices/168

First,  I would like to introduce a project : the solar meteorologic station http://www.yeelink.net/devices/168   founded  by  @CSK_ (a sina weibo user)

这个是我今晚在weibo上看到的,看到后,立刻觉得这是数据采集系统的一个绝好诠释。@CSK_ 在他的blog (本站友情链接里面有)里有过介绍这个数据采集系统的制作工作。由上面的图标可以看出,一定时间跨度上数据获取显示和统计,足以表现出十分有用的信息。

This is the scope I saw on the sina weibo. It explains what  the Process Data Acquisition System looks like. in @CSK_ ‘s blog, he showed how the solar meteorologic station works. With the scope above we will find the trend of the weather, that is a kind of useful information.

回归正题,在工业现场,比如加工制造领域,常常需要对某些数据进行监控,一般来说,这些重要的监控数据都已经被系统开发者做进了系统功能中,但是同时也失去了灵活性,有时候需要针对性地对某些对象进行监控,就需要相应的工具。这个,工业界的软件开发商已经为我们考虑到了。高级一点的,各种SCADA系统(即Supervisory Control And Data Acquisition),简单点的各种PDA系统。甚至,你在机器人程序当中编写了一段程序为了获取某个数据,也可以成为PDA了。

Now we back to the industrial filed , the process control person always need to monitor different  data. traditionally, these functions were integrated into the software, but not enough flexible. some object need to be monitored specially by some tools. So some software company have developed these tools, including some  SCADA systems and some PDA systems. Even you can also write your own PDA function in your robot program.

这里介绍两款通用的软件。一个是AUTEM公司出品的 PLC-ANALYZER pro,一个是iba公司的ibaPDA。前者,LT已经在另一篇日志里面做了介绍,详见 “PLC-ANALYZER pro – PLC信号时序分析软件” ,在某些场合,LT甚至觉得比PLC系统自带的功能都好用,下图就是LT在某S7-300上追踪信号的记录。

Here I would like to introduce two software systems: one is the PLC-ANALYZER pro come from AUTEM company, the other is the ibaPDA come from the iba company. About the PLC-ANALYZER pro , LT had written some in “PLC-ANALYZER pro –_tools_plc” (link), It is more efficient than the step7 used for monitoring.  Below is a example.

另一款软件ibaPDA更为强大,据介绍说支持很多接口,而且这个软件貌似在钢厂等行业用的比较多。(不过,这个软件 LT 没有实际验证过效果。)

the other software, the ibaPDA is more powerful, it is said that have many interface , also used widely in steel factory, etc.
