1. System composition The system is a software platform based on a combination of standard PC hardware platform and Linux and RTLinux. The device driver layer adopts field bus interconnection and connects with external network or INTRANET via Ethernet to form a pure software combination of reconfigurable configuration. High-end open architecture CNC system platform for multimedia and network technology. The platform CNC system runs on a standard PC hardware platform without a motion control card. The software platform uses a combination of LINUX and RTLINUX, some time-critical tasks, such as motion planning, acceleration and deceleration control, interpolation, fieldbus communication, PLC, etc. , Realized by RTLINUX, and some other time-inefficient tasks are implemented in LINUX. See the software block diagram for details. The connection between the controller and the drive device and peripheral I/O is based on a standard PC. A magnetically isolated high-speed RS422 standard field bus is used. When the communication rate of each channel of the bus is 12 Mbps, the communication distance using an ordinary twisted pair can reach 100 meters. The host side is a PCI bus card with four channels (actually only two channels are used - one channel to connect the machine operator panel and the other channel to connect the device and I/O). The device interface is converted to standard motor control by the DSP chip. signal. Each channel can have up to 32 control nodes. Each node can control one axis (synchronized linkage between the axes through the broadcast synchronization signal in the communication protocol) or a set of analog interfaces (measurement interfaces, system monitoring sensor interfaces, etc.) ) or a group of PLC I/Os (up to 256 points), the total number of PLC points is up to 2048 points (see figure fieldbus network topology). 2, the main features of the system: (1) The controller has the function of dynamically recognizing the system interface card. The system can be reconfigured to meet the numerical control requirements of machine tools and equipment of different processing technologies. The drive motor can be equipped with digital servo, analog servo and stepping motor; (2) Network function. Through Ethernet (does not need outdated, expensive, lack of extensive support for MAP protocol) to realize the interconnection of CNC system with workshop network or INTRANET/INTERNET, and use TCP/IP protocol to open the internal data of CNC system to realize the relationship with production management system. High-speed bidirectional data exchange on external networks. With conventional DNC function (faster than the traditional 232-interface DNC with a 112K speed of 112K faster DNC speed), production data and machine operation data management functions, remote fault diagnosis and monitoring capabilities; (3) In addition to the standard parallel port, serial port (RS232), PS2 (keyboard, mouse port), USB interface, and Ethernet interface, the system is equipped with a high-speed field bus interface (RS422) and PCMCIA IC Memory Card (Flash ATA). Interface, infrared wireless interface (with tool detection sensor); (4) The display screen uses a 12.1-inch TFT-LCD. Using the unified user interface style, 18 dynamic soft keys in two rows, horizontal and vertical, can meet the operating requirements of different machining tools. Users can define the dynamic soft keys through the configuration tool. The vertical softkeys can be changed according to the function selection of the horizontal softkeys. The vertical menu can be multiple pages. (5) Apply multimedia technology to the operation, use, training and fault diagnosis of machine tools, improve the ease of use and the controllability of the machine tool, and reduce the use cost. Multimedia technology provides operational assistance, online tutorials, troubleshooting and machine maintenance wizards; (6) It has a three-dimensional dynamic machining simulation function; it uses OpenGL technology to provide three-dimensional machining simulation functions and dynamic display of tool path during machining; (7) With Nurbs interpolation and adaptive Look Ahead, high-speed interpolation of arbitrary curves and surfaces can be achieved. Output motor control pulse frequency up to 4MHz (using direct digital synthesis DDS IC implementation), when the resolution is 0.1mm, fast forward speed up to 24 meters, if necessary, can output a higher frequency), suitable for high speed, High-precision machining; (8) Servo update up to 500ms (control 6-axis, PENTIUM = 3 \ * above ROMAN III CPU), PLC scan time is less than 2ms; (9) PLC programming complies with the International Electrotechnical Commission's IEC-61131-3 specification, providing ladder diagrams and statement list programming; (10) Adopt high-reliability industrial control board (SBC) to strengthen the hardware and software reliability measures to ensure that the mean time between failures (MTBF) of the CNC system reaches 20,000 hours; (11) Meets the European Electromagnetic Compatibility Standard (Directive 89/336/EEC) Level 4 requirements; (12) The price of the CNC system itself (excluding servo drives and motors) may be 1/2 of that of the popular and high-end CNC systems with existing functions.
