飞机蓄电池输出电压微型监测仪的设计与仿真

Design and Emulation of Mini-testing Meter of Outputting Voltage of Plane Storage Battery

为便于掌握飞机蓄电池的工作状态,设计了输出电压微型监测仪。其硬件系统包括串联分压电路、A/D转换电路、单片机、微型液晶显示器和报警电路等;软件系统包括A/D转换的驱动程序、液晶驱动程序和监测数据处理三个模块。基于Proteus软件平台对系统的设计进行了仿真,结果表明,系统的软硬件设计正确,运行可靠。

For the sake of mastering the working state of plane storage battery, mini-testing meter of its outputting voltage was designed. The hardware included lowering voltage circuit, A/D transforming circuit, single chip, mini liquid crystal display and alarming circuit. The software included three module, which are respectively the driving program of A/D transforming, the driving program of liquid crystal display and the testing data processing program. On the basis of Proteus software, the emulation of the design was conducted. The results show that the design of the system is right and the system can work reliably.
