摘　　要：使用电阻式扭矩传感器与FPGA器件实现高精度扭矩传感系统设计。传感器将外界的扭矩信号转化为频率信号,频率信号的范围5～15 kHz.利用QUARTUS II软件与VERILOG语言编写程序,通过FPGA芯片实现出等精度频率测量系统,并对频率信号进行采集,计算出扭矩数值,最后通过LED显示。文中给出了扭矩测量系统的原理图,并对VERIL-OG编写的等精度测量方法模块进行了仿真,并得到很好的效果。This paper used resistive torque sensor and FPGA devices to design high-precision torque sensor system. The sensor transformed the torque signal into a frequency signal;the frequency signal range is from 5 kHz to 15 kHz. Combined QUARTUS I1 software with VERILOG programming language, the paper designed the FPGA frequency measurement system. It acquired the fre- quency of signal, calculated the torque values, and finally displayed through the LED module. This paper presented a schematic dia- gram of the torque measurement system, the accuracy of measurement methods, VERILOG written modules for simulation, and got better results.
