摘要
以单片机AT89S52为核心,设计了一种低压电网频率监测仪,完成了对低压电网频率信号的精确测量。同时实现监测数据的统计、通信、人机交互等功能,并讨论了该监测仪的工作原理和软硬件结构,给出了基于PROTEUS仿真软件的实现,证明该方法具有一定的实用价值。
An instrument for measuring the frequency of low-voltage electric network is introduced and its basic principle, software and hardware structure are also described, which is base on MCU AT89S52. The instrument can monitor frequency signal simultaneously and possess such functions as the data storage, communicate with PC server, human-machine communication. The validity of this method is verified by PROTEUS, which is a co-simulation of microprocessor software within a mixed mode SPICE simulator. The results prove that this method has some practical value.
