基于单片机的电感测量系统

Inductance Measurement System Based on Single-chip Microprocessor

提出一种以8031单片机为核心的电感测量系统,充分利用了单片机8031的硬件资源,简洁而高效运行的软件设计思想,实现电感参数的自动测量和显示。克服了传统的外加交流测量法电源波动易引起偏差和文氏电桥测量法参数调节复杂等问题。系统结构紧凑、操作方便,且测量精度高、响应快、测量范围宽。

A novel inductance measurement system based on the 8031 single-chip microprocessor was proposed, which hardware resources were fully exploited. The design of software is simple and high efficient. The inductance parameter was calibrated and displayed automatically. The system overcomes the traditional shortcomings of source-supply ripple in the exterior alternating current supply method and of regulating complexity in the electrical bridge method.The system was characterized by simple structure, easy regulation, high measurement precision,rapid response and big measurement scale.
