IPC（工控机）和PLC的选择

比方说球磨机的自动控制系统，用加速度传感器采集球磨机的轴振，再通过傅利叶变换取出球磨机内存煤量的特征频率，用来控制球磨机的供煤速度。在球磨机的控制环境中需要用到像傅利叶变换之类的复杂算法，如果用PLC实现会比较困难，所以好采用IPC，并用C、C++开发对应的控制算法，如果需要为可靠的控制，我们可以将IPC的结果再交给PLC来控制。

早在上世纪90年代很多分析报靠认为到2000年以后，PC_BASE（基于PC技术开发）的产品将替代掉大部分PLC，但实际明他们错了，PLC不光没消失，它还吸收了单片机和PC的很多新技术，越来越有生命力了。现在的产品中的大多数PLC都使用了单片机、IPC和各种专用处理器来实现，应该说PLC是单片机、PC技术的受益者，特别是现代的PLC与PC的分界已越来越小，很多PLC也可以演算一些很复杂的算法，包括傅利叶变换、相似度较等。

IPC (Industrial Control Computer) and PLC selection

For example, the automatic control system of the ball mill, the acceleration sensor is used to collect the shaft vibration of the ball mill, and then the characteristic frequency of the coal quantity in the memory of the ball mill is taken out through the Fourier transform, which is used to control the coal supply speed of the ball mill. In the control environment of the ball mill need to use complex algorithms such as Fourier transform, if the PLC implementation will be more difficult, so it is better to use IPC, and C, C++ to develop the corresponding control algorithm, if the need for reliable control, we can IPC results to the PLC to control.

As early as the 1990s, many analysts believe that after 2000, PC_BASE (based on PC technology development) products will replace most of the PLC, but the fact that they are wrong, PLC not only did not disappear, it also absorbed a lot of new technologies of single-chip computers and PCS, more and more vitality. Most of the PLC in today's products use single-chip microcomputer, IPC and a variety of dedicated processors to achieve, it should be said that PLC is the beneficiary of single-chip microcomputer, PC technology, especially the modern PLC and PC boundary has become smaller and smaller, many PLC can also calculate some very complex algorithms, including Fourier transform, similarity and so on.
