摘要
介绍了基于80C196控制的改进型智能金属探测仪的研制工作.采用软件控制CPU输出一频率递增的脉冲信号并对其进行扫频、选定工作频率f0,最终提出了以CPU输出频率为f0的信号作为整个系统基准频率信号的新方案,并且给出了系统硬件组成和软件控制流程.
This paper presents the study and the implementation of the improved intelligent metal detector based on 80C196. A new scheme was proposed that the software can be used to control the CPU to output a pulse signal with an increasing frequency, to sweep the frequency of this pulse signal and to select the operation frequency from it. In this way, the signal with the frequency was finally output by the CPU as the reference frequency signal for the overall system. The architecture of the system hardware and the software control process are also provided in this paper.
