The CCC and L3 systems use Ethernet network communication to transmit production task information, and Ethernet communication is also used between the NC system and the NC system. The system design is simple, stable and reliable. CCC can automatically determine the online status of each NC system. The system can automatically monitor and automatically complete each other's communication tasks online and offline. A CCC computer can manage multiple NC computers. In the Baosteel Heavy Plate project, there are 3 CCC computers and 7 NC computers in Phase I and Phase II projects.

The NC computer is placed in the operating room of the flame cutting machine, receives the cutting task forwarded by the CCC through the Ethernet, and is responsible for controlling the specific cutting device to complete the product cutting task according to the production task requirements. The NC computer communicates with the underlying Mitsubishi motion controller, Mitsubishi QPLC, temperature measuring equipment, and punching equipment through SSCNET, Ethernet, serial port, and monitors the cutting and punching production process. According to the configuration system, it is possible to control up to 14 motion axes, 6 cutting guns, one temperature measuring head and one punching head to simultaneously move. The program calculates the cutting path according to the cutting task selected by the user and the scanning result of the steel plate contour; automatically measures the temperature during the cutting process and performs path compensation, and according to the calculation result, the cutting gun is automatically completed according to the requirements of the cutting process, and the entire cutting process is monitored. .
3. System features
(1) High cutting precision. In the production line up to 8*60 meters, the maximum cuttable product is 5×25 meters, and the maximum thickness is 400mm. The product size error after cutting is not more than 1mm.
(2) Powerful. Its unique waste edge cutting, double-station multi-head cutting and other functions are unique to the system.
(3) Cutting with temperature steel plate. According to the data calculation, after the steel plate with a length of 20 meters and 500 degrees Celsius is cooled to normal temperature, its length will be reduced by up to 25 mm. The unique temperature monitoring and compensation algorithm of the system can control the system to adjust the cutting path at any time, thus ensuring thermal cutting. In the case of cooling, the product meets the product accuracy requirements.
(4) The process is complicated. The main processes include: scanning steel plate profile, product nesting, cutting path optimization, automatic cutting control, punching factory marking, task reporting, etc.
(5) There are many communication equipments, including four kinds of communication devices: motion controller, Mitsubishi QPLC, temperature measurement, punching equipment, etc. All of them use serial communication mode, and the motion controller can control up to 14 axes for linkage.
4. Software application
Based on the easy-to-control (INSPEC) software, the system software adds different service modules according to different service types, and each module interacts through interfaces, thereby ensuring the flexibility and scalability of the system architecture. The underlying architecture of the system is based on Microsoft's .Net platform, using the latest technologies such as .Net Remoting and XML to ensure the advanced nature of the system. The good openness of the easy-to-control (INSPEC) makes it easy to add algorithms and special function modules.
The entire cutting task includes task selection, steel plate contour scanning, contour fitting, product nesting, path optimization, automatic cutting, punching identification, performance reporting and many other processes. The system automatically saves the process completion status of each task, pauses during the process or during the process execution, and resumes the process task after the next time the program is entered.
Task management: Before each process, you must select the cutting task to be executed. The cutting task is distributed by the upper CCC computer. When a network failure occurs, CCC can automatically save the cutting task that needs to be transmitted, and transmit it when networked. . You can also enter the cutting task manually when there is no network.
Contour scanning: Before the steel plate is cut, the contour of the steel plate must be scanned first. The main purpose of the contour scanning is to determine the shape and position of the steel plate, automatically scan the loading position and actual size of the steel plate, and automatically fit the outer contour of the steel plate. Contour scanning uses laser scanning for edge detection. The computer controls the scanning head to move directionally. When the scanning head passes the edge of the steel plate, an interrupt signal is generated. The PLC automatically records the position signal and transmits these signals to the upper machine easy to control (INSPEC) configuration software. A fitting process is performed. In practice, the accuracy of the data is affected by the moving speed of the scanning head. Based on a large number of practices, it is inferred that the calculation formula dynamically compensates the scanned data to ensure the scanning accuracy.
In addition to automatic scanning, for steel plates of a regular shape, the position and contour of the steel plate can also be determined by determining the feature points.
