Għaliex is-sistemi ta 'kontroll awtomatiku għandhom it-tendenza li jużaw kompjuters industrijali? Prodotti tal-kompjuter industrijali integrati huma meħtieġa f'ħafna industriji. X'inhu kompjuter industrijali? Fil-fatt, kompjuters industrijali huma kompjuters industrijali, u kompjuters industrijali huma ddisinjati għall-kontroll tal-produzzjoni industrijali. Il-kompjuter jintuża biex jimmonitorja u jikkontrolla t-tagħmir, il-proċess tal-produzzjoni, il-parametri tad-dejta, eċċ fil-proċess tal-produzzjoni industrijali. Għalhekk, meta mqabbel ma 'PCs u servers personali, l-ambjent tax-xogħol tal-kompjuters industrijali huwa ħarxa ħafna, u r-rekwiżiti għas-sigurtà tad-dejta huma għoljin ħafna.
F'dawn l-aħħar snin, l-iżvilupp ta 'awtomazzjoni industrijali u robots industrijali kien mgħaġġel ħafna, u hemm żewġ soluzzjonijiet fis-sistema ta' kontroll awtomatiku ta 'tagħmir mekkaniku u robots: waħda hija li tuża sistema ta' kontroll ibbażata fuq PC-; l-oħra hija li tuża sistema ta' kontroll industrijali bbażata fuq kompjuter-. Iżda f'applikazzjonijiet prattiċi, soluzzjonijiet ibbażati fuq kompjuters industrijali huma aktar prattiċi. Għalkemm fil-proċess ta 'żvilupp, is-sistema ta' kontroll ibbażata fuq PC-tabilħaqq ġabet bidliet kbar fil-kontroll awtomatiku ta 'tagħmir mekkaniku u robots, ġiet imqabbla u vverifikata ripetutament f'applikazzjonijiet prattiċi. Meta mqabbel mas-sistema ta 'kontroll tal-kompjuter industrijali, tabilħaqq hemm ħafna żvantaġġi u insuffiċjenti. Allura għaliex is-sistemi ta' kontroll ibbażati fuq PC-rari fil-kontroll attwali? Għaliex is-sistemi ta 'kontroll awtomatiku jippreferu jużaw kompjuters industrijali?
Because PC-based control systems are more fragile than dedicated controllers, and are more likely to be damaged in collisions or other damages. Moreover, the use of a PC-based control system will make the startup 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 system security is also one of the important factors that need to be considered. So many times we regard PC-based control system as an inefficient control system with potential safety hazards, which has prompted manufacturers to choose more dedicated controllers.
When the safety management software is embedded in the industrial computer, its basic function is to maintain the normal operation of the system. However, there may be some risks that are difficult for us to predict. For example, when a virus invades the control software or resets the firewall, it may cause some basic functions of the system to fail and paralyze.
The process control system is more sensitive to the interruption of the control program than the operation of the machine, and the system breakdown is more likely to cause the shutdown, so the stability of the system has become a key factor. If a robot control system fails, then we at most stop the robot's production line, but if the process control system fails, it may cause the entire production line to stop, and it will bring a series of serious consequences.
But now the hardware system of industrial computer is now very stable. They have been able to adapt to harsh industrial site environments such as strong earthquakes and high temperatures. They are as stable and reliable as traditional PLC control systems. Many people associate industrial computers with windows systems, believing that they are afraid of collisions and are prone to malfunctions. But industrial computers support Linux, windows or other systems, such as the popular Android system. And their reliability has also improved a lot: the system has real-time monitoring functions, and some users also use FPGAs in conjunction with high-performance data processors to run the real-time control system on the FPGA.
Of course, the research on the rationality of control is still continuing, especially in the field of control that requires backup systems. For those occasions that need to switch from one system to another without buffering, PC-based controllers show 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.
