Information
In recent years, the development of industrial automation and industrial robots has been extremely rapid, and there are two solutions in the automatic control system of mechanical equipment and robots: one is to use a PC-based control system; the other is to use an industrial computer-based control system . But in practical application, the solution based on industrial computer is more practical. Although in the development process, the PC-based control system did bring tremendous changes to the automatic control of mechanical equipment and robots, but after repeated verification in practical applications, compared with the industrial computer control system, there are indeed many disadvantages and insufficient. So why are PC-based control systems extremely rare in real-world control? Why does the automatic control system prefer to use industrial control machines?
 
Because PC-based control systems are more fragile than dedicated controllers, they are more likely to be damaged in the event of a collision or other damage. Moreover, the use of a PC-based control system makes the start-up of the control system more complicated, and it is difficult to do well in terms of cost savings. At the same time, the lack of security of the system is also one of the important factors to be considered. So in many cases, we consider the PC-based control system to be an inefficient control system with potential safety hazards, which prompts manufacturers to choose more dedicated controllers.
 
When the safety management software is embedded in an industrial computer (industrial PC), its basic function is to maintain the normal operation of the system. However, there may be some risks that are difficult to predict. For example, when a virus invades the control software or resets the firewall, this may invalidate and paralyze some basic functions of the system.
 
The process control system is more sensitive to the interruption of the control program than the operation of the machine, and the system paralysis is more likely to cause shutdown, so ensuring the stability of the system has become a key factor. If a robot control system fails, then at most we stop the robot's production line, but if the process control system fails, it may cause the entire production line to shut down, and it will bring a series of serious consequences.
 
But now the hardware system of the industrial computer has been made very strong. They have been able to adapt to the harsh industrial field environment such as strong earthquakes and high temperatures. They are as stable and reliable as the traditional PLC control system. Many people associate industrial computers with windows systems, thinking they are afraid of collisions and are prone to failure. But industrial computers support Linux, windows or other vendor-developed software systems. And their reliability has also improved a lot: the system has real-time monitoring capabilities, and some users also use FPGAs and high-performance data processors in conjunction to run real-time control systems on FPGAs.
 
Of course, the research on the rationality of control continues, especially in the field of control that requires backup systems. For those who need to switch from one system to another system without buffering, PC-based controllers have shown greater advantages. With a DCS system, a single-loop controller, and some PLC-based control systems, the control program and software control are relatively independent, so the use of industrial computer control is simpler and more convenient to operate than direct program control.
