针对传统的电阻测试系统存在的多种问题,研制了一种基于89C52单片机的电阻测试系统。该系统以单片机为控制核心,结合555电路构成的多谐振荡电路,利用汇编语言进行编程。使测试系统具有测量精度高、性能可靠、智能化及自动化程度高等优点,弥补了传统测量方法的不足。
Aiming at many problems existing in the traditional resistance test system, a resistance test system based on 89C52 single-chip microcomputer is developed. The system to the microcontroller as the control center, combined with 555 circuit multivibrator circuit, the use of assembly language programming. The test system has the advantages of high measurement accuracy, reliable performance, intelligent and high degree of automation to make up for the shortcomings of the traditional measurement methods.
