| In recent years, the artificial turf has been improved obviously in the aspects of stability, lawn maintenance, sliding resistance and appearance color, and is increasingly close to the natural lawn, so it is more and more applied in the field of international competition.To strengthen the people’s constitution is the basic national policy of our country, the domestic sports industry is rising, which led to the growing demand for artificial turf, and more high quality requirements.Artificial turf loom as the main equipment to product artificial turf, the principle is similar to tufting machine, which the key technology is monopolized by the developed countries, and the technol ogy is relatively backward. However,since the late start ofthe tufting technology of our country, the majority of the tufting machineare dependent on imports, and not the advanced models, and the price is very expensive, the production efficiency and quality have a gap compared to the foreign country.Only by improving the tufted efficiency, improving product quality and increasing the level of the automation, tufting machine can stand in a good position to compete in the market.Many enterprises take advanta ge of the existing domestic machinery manufacturing level, to make some of the mechanical part of the small lawn machine, the design of the control system is the biggest difficulty, and ultimately lead to the development of failure.Firstly, based on the research of the control system of the domestic and foreign tufting machine and artificial turf loom, Through the analysis of the mechanical structure and performance requirements of BLT5 artificial turf machine, a overall design scheme based on CANopen bus technology is presented. In this control system, the principle of upper and lower computer control is adopted. The upper computer is the touch screen, the lower computer is the motion controller, the inverter and servo driver. The communication between the upper and lower computer is realized by CANopen bus. PC touch screen is Schneider HMIGX, to edit man-machine interface by Vijeo-Designer software. You can select the operating mode, manual mode and automatic mode. Manual mode can be achieved by trimming handheld handle. In the automatic mode, the PC monitors the running state of the lower computer, and receives the information of the motor rotation speed delivered by the lower computer. At the same time, the alarm module can be used to monitor the system. The core of the lower computer is the Schneider LMC20 motion controller, which receives information controlled by the upper computer, and processes data, then sends the signal to the converter ATV71 and the servo driver through the CANopen bus, ultimately control the speed of each motor. According to the specific requirements of the process, the Codesys software is used to design the motion controller, and each module is connected to the bus as a CANopen node.All the electrical components of the system are come from Schneider products, and the system has been improved and perfected. The hardware and software have been finished on-site installation and commissioning. The upper computer and the lower computer are working properly, to meet the design requirements. |
