The embedded integrated industrial control machine is a single-chip microcomputer control system integrated with the industrial control workbench. [1] It is equipped with a suitable-sized liquid crystal display screen to show the working menu. It can be connected to a standard keyboard, and the display content includes text, serial numbers, dates, and graphics. It can be connected to a PC and other devices via RS232 serial port or USB interface; the CF card interface can be connected with an 8M-2G CF card. NAND Flash is used as stable storage; there is a JTAG interface for debugging; there are three panel buttons (confirmation button, down button, return button) and an emergency stop button for independent control of the operation; it supports multi-language menus, etc. Due to the use of a high-performance processor and related peripheral hardware equipment, the data communication protocol of this system is more reliable, reasonable, and easy to expand; the human-computer interaction operation is more friendly and convenient; the system integration is higher and the volume is smaller. This system can work independently as an embedded system. It can also be controlled by a PC as a subordinate functional device to complete more complex tasks. This system has three working modes: independent working mode, online working mode, and maintenance working mode.
In mechanical and electrical integration projects, situations often occur where workpieces need to perform round-trip movements or precise positioning. These projects use stepper motor control which is simple and feasible. Therefore, the embedded integrated industrial control machine containing stepper motors is widely used and can be used as the control system for pneumatic processing, laser processing, automatic welding, etc. For example, the mechanical and electrical integration equipment that can print text and graphics on various metal or non-metal objects – the marking machine, when using this system, can significantly increase the speed and accuracy of marking; another example is the laser processing machine, which cuts, punches, and heats various components by controlling the relative position between the laser beam and the workpiece. Using this system can fully utilize the performance of the ARM processor. It can improve accuracy while reducing production costs, which is an effective way for new machine design and old machine renovation.
