基于单片机的多时段远程抄表系统设计

Time-Division Remote Meter Reading System Design based on SoC

随着我国国民经济的快速发展,各行各业对用电量的需求也迅猛增加,与此同时,电能需求的波动性使发电能力得不到有效利用。本文选择单片机作为主芯片,设计了一种多时段远程抄表系统终端。系统采用BL0932B作为电能计量芯片。将电能转化为脉冲数,输入到单片机的计数接口。利用RX8025提供的精准时钟,RX8025产生中断,调用分时段处理程序作相应处理。此外,系统针对应用坏境的恶劣情况,在软硬件设计时采用了大量抗干扰措施。

With the development of the national economy, the demands for the eIectric energy are increasing greatly, at the same time; the fluctuations of the demands result in huge wastes of power generate abilities. A remote meter reading terminal is designed based on AT89S52 to implement those functions. BL0932B is used to measure power. BL0932 convert power into pulse, which is the input of pulse counter of AT89S52. RX8025 is used as time division clock. When the time is equal to setting value, interrupt is generated and time segments time division charge is remotely division dealing program is called by AT89S52. Plenty of techniques are used for anti-jamming.
