【摘要】 提出了一种硬件实现简单的交流电压间接测量方法,在MATLAB/Simulink环境下用仿真方法建立了求电压公式,并提出了公式法和查表法两种实现方法。测量硬件电路主要由1片89C552C单片机组成,而不需要模数(A/D)转换器。经仿真和应用于实际生产,证明了该方法的有效性。更多还原

【Abstract】 This paper presents an AC voltage indirect measurement method whose hardware implemented is simple. The voltage equation is set up by simulation method using AB/Simulink tool. Two methods implemented are advanced such as formula way and lookup table way. The measured hardware includes one 89C51 SCP (single-chip computer) without A/D conversion. Results of simulation and application confirm the validity of this method.更多还原
