摘　　要：在工程应用和科学研究中,经常需要对脉冲宽度进行精确测量。在此设计一种电路,采用51系列单片机作为核心控制部件,用液晶显示模块LCM1602作为显示部件,可以对脉冲宽度进行精确测量。结合EDA现代电子技术,在Protues仿真软件中进行仿真测试,测试表明该电路具有性能稳定、精度高、成本低的优点。It is necessary to measure pulse width accurately in engineering application and scientific research. In this pa？per,a circuit with 51 series microcontroller as its core control unit,and with the liquid crystal display module LCM1602 as its display part is designed. It can accurately measure the pulse width. Combined with EDA modern electronics technique,simula？tion testing was carried out on Protues simulation software. The testing result shows that the circuit has the advantages of stable performance,high precision and low cost.
