The production of braiding machines in China has developed rapidly, and users' requirements for products are also increasing. However, domestic braiding machine technology innovation is still relatively lagging behind, and improvements are needed in mechatronics aspects such as automation, continuous operation, intelligence, and high speed. The high-speed braiding machine monitoring system utilizes microelectronics technology and variable frequency stepless speed regulation, greatly improving the performance of braiding machines. This study mainly introduces a high-speed braiding machine monitoring system based on an RS458 local area network. [b]1 System Framework and Working Principle 1.1 High-Speed ​​Knitting Machine Monitoring Local Area Network[/b] The high-speed knitting machine monitoring local area network is established based on RS485 serial communication, as shown in Figure 1. Using the RS485 serial bus, only one pair of balanced differential signal lines is needed to collect data from multiple remote control systems. Lines A and B in the figure are the RS485 bus. Each monitoring subsystem is equipped with a transceiver for RS485 communication, which can convert TL level signals into differential signals. Then, through the RS23/2RS458 conversion module, the differential signals are converted into RS-223 level signals and transmitted to the host computer. Similarly, RS-223 level signals from the host computer can also be converted into differential signals, and then the transceivers of each subsystem restore the differential signals to TL level. Using differential signals can greatly improve the communication's anti-common-mode interference capability and receiving sensitivity.
