Combined woodworking processing equipment with independent A/D (analog/digital) conversion module

Abstract

The invention discloses combined woodworking processing equipment with an independent A/D (analog/digital) conversion module. The combined woodworking processing equipment comprises an FPGA (field programmable gate array) processing module. Expansion bus is connected onto a pin on a side of the FPGA processing module, an ARM [advanced RISC (reduced instruction set computer) machine] processing module is connected onto a pin on the other side of the FPGA processing module, and the A/D conversion module which is used for receiving external analog signals, converting the external analog signals into digital signals and transmitting the digital signals to the FPGA processing module via the expansion bus is connected onto the expansion bus. The combined woodworking processing equipment has the advantages that the independent A/D conversion module is expanded on the basis of FPGA bus, the analog signals acquired by external sensors can be directly converted into the digital signals by the independent A/D conversion module, the digital signals further can be transmitted into an FPGA via the expansion bus, accordingly conversion processing work on data in the FPGA processing module can be replaced, increase of excessive load on a CPU (central processing unit) can be prevented, multi-source fused information of the multiple sensors can be fed in real time, requirements of diagnosis modules on the real-time capacity can be met, and real-time sensing, feedback and control network modules of integral components of high-precision turning, milling and drilling combined numerical-control systems can be built under the condition of electromechanical-multi-source information cross interactive behavior mechanisms in complicated information environments.
