The users of the industrial computer are not "game consoles" for home or office or entertainment, but most of them are industrial users. The so-called industries refer to power automation, intelligent transportation, automated field, communication and telecommunications, web security, medical construction, CNC machine tools, textile machines, etc. These are industries that are likely to be at war but do not feel it, almost everywhere. The industrial computer calms things down here. Naturally, these industries are all users of industrial computers!
The industrial computer is a numerical control system that uses a micro processor or a special computer. The system program (software) stored in the memory in advance realizes the control logic, completes one-sided or all numerical control functions, and combines with the peripheral structure through the interface, which is called a computer. Numerical control, referred to as CNC system.
The industrial computer adopts a programmable memory, in which the instructions for performing logical operations, sequential control, timing, counting and arithmetic operations are stored, and through digital or analog input and output to master various types of machine architecture or production process. The current numerical control system adopts the module structure, and its function covers a large area, from the machine tool with three axes and two linkages to the flexible machining unit with more than 24 axes. Since the 1980s, various flexible production systems based on CNC machine tools have emerged. According to the differences in their specifications, automation levels and control methods, they can be divided into flexible production units, flexible production systems, flexible water lines, independent production islands, computer-integrated production systems, and intelligent production systems.
The IPC programmable controller is a new general-purpose automatic control device developed by the combination of computer technology and automatic control technology, which is suitable for industrial conditions. It was discovered as a substitute for ancient relays. With the rapid development of microelectronics technology and computer technology, programmable controllers have more functions of computers, not only can realize logic control, but also have functions such as data processing, communication, and web pages. Because it can change the control process through software, and has the characteristics of small size, convenient assembly and maintenance, simple programming, high reliability, strong anti-interference ability, etc., it has been widely used in various platforms of industrial control, greatly promoting the development of mechatronics. course.
The industrial computer improves the processing accuracy, and the high{{0}}resolution rotary encoder is indispensable. In order to achieve the accuracy of 0.001 micron on the ultra-tight processing platform, it is necessary to develop ultra-high-resolution coding and NC assembly of small setting units of 0.0001 microns. In order to keep the characteristics of the servo system fixed even if the load changes during processing, it is necessary to adopt control and robust (R0bust) control. In the control of the servo system, a high-speed micro processor is used to adopt feedforward control, two-degree control, and learning control based on contemporary control theory. The tracking deviation of its digital control system does not exceed 2 microns.
The industrial computer is a new technology in the NC platform. The so-called machine intelligence function refers to the function that the machine itself can compensate for machine deformation caused by temperature and machine load. It is necessary to check the sensor of the spindle load, the deformation of the spindle and the base, and the circuit that handles the output signal of the sensor. This sensor itself has the function of signal processing, so it is called a smart sensor. Artificial intelligence will be suitable for the PMC of the disposal lights.
