  1. This system is developed based on high performance, low cost and many controllers inside of the embedded processor, and enlarged gpio for the plat of the hardware and software. this system is applied to the high - speed numerical control carving machine. show the operate interface by lcd, input the control code from the keyboard, the data is readed from the usb interface and store that in sdram

    本系統應用於高速數控雕刻機,以lcd為人機可視化操作界面,以編碼盤為操作控制部分,以嵌入式處理器s3c44b0x晶元為核心,文件數據經usb口讀取u盤中的雕刻數據文件暫存於sdram中,經嵌入式處理器進行相關演算法處理,得出相應參數傳送到fpga ,由fpga控制輸出脈沖和脈沖延時,通過高速光耦離( 2mbit / s )后輸出,控制步進機的運轉。
  2. In signal processing circuit, the key of our study, based on methods of mcu + cpld and a / d converter, a time interval measurement unit is done, in which an isp cpld counter is carried out to judge laser pulse for controlling counting and offering signal of time series and control, and a count quantization error measurement circuit which main ramp circuit and 12 bits a / d conversion circuit guarantees the resolution of system

    信號處理部分是本文研究的關,採用mcu + cpld的設計方法和模數轉換技術構成時測量單元的理論基礎,其中用可在系統編程的cpld計數器實現了對循環光脈沖的判斷以開關計數,並提供計數量化誤差測量路相應的時序和控制信號,用斜坡路和12位a / d轉換路完成對計數量化誤差的測量,保證了系統的解析度。
