基于FPGA GTP光纤传输的贾卡梳控制器设计
|
摘要
随着拉舍尔压电式贾卡经编机往多梳节,大花型,多针床等方向的不断发展,以CAN总线为代表的传统工业现场总线满足不了经编机实时花型数据传输要求,有鉴于此,该文设计了一种基于FPGA的GTP光纤数据传输的压电贾卡梳控制系统。该控制系统收发双端主控芯片采用Xilinx Virtex-5系列的XC5VLX50T18的高速GTP接口实现了高速数据传输,在经编机运转时,根据主轴触发信号,将相应位置的花型信息利用光纤收发模块输送至压电贾卡梳驱动器。实验表明,该FPGA贾卡控制器传输速率可工作在触发频率6K的速率上并使当前RD6机型的转速由850rpm提高到3000rpm左右。因此该控制系统具有良好的应用前景。
With the development of Raschel piezoelectric Jacquard warp knitting machine toward to multi-section, large flower pattern, multi-needle bed and other directions, The CAN bus as the representative of the traditional industrial field bus can not meetthe warp knitting machine real-time pattern data transmission requirements, In this paper, we design a piezoelectric jacquard control system based on FPGA GTP fiber data transmission in which Xilinx Virtex-5 Series XC5VLX50T18 GTP was adopted as dual-ended master chip to achieve a high transmission speed, When warp knitting machine start working, the spindle signal will triggerthe corresponding position pattern data to be delivered using optical fiber transceiver module to the piezoelectric jacquard driver.The Experiments show that the FPGA Jacquard controller can work under the 6 K trigger frequency and make RD6 model speed increased from 850 rpm to 3000 rpm. Therefore, the control system has good application prospects.
