摘要
针对目前某领域使用的磁通门传感器信号处理电路的一些缺点:如设备体积大、维护和升级困难、元件间容易出现感应和杂散效应等,提出了采用DSP的磁通门信号处理电路的数字化设计方案,给出了处理电路的硬件设计,并且对信号处理中的数字滤波进行了计算机模拟仿真。仿真结果表明,改造后的系统具有精度高、实时性好、升级方便等特点。
Considering some defects in the fluxgate signal processing circuit used in a certain area, such as big size, difficulty in maintenance and upgrading, and inductions and scattered effects among electron devices, a digitized design for the fluxgate signal processing circuit adopting DSP was presented and also the design of the circuit. The digital filtering plan was simulated on computer. The result proves that the new system is characterized by high precision, good real-time performance and programmable flexibility.
