飞机主系统液压泵转速测试仪的设计与仿真

为给主系统液压泵转速装置的定检提供参考，设计了主系统液压泵转速测试仪。硬件设计包括单片机和液晶显示器四个模块；软件设计包括定时器T0的中断服务、计数器T1的脉冲计数和液晶的驱动三个模块。基于Proteus平台并利用模拟的霍尔脉冲信号对设计进行了仿真，结果表明，测试仪的软硬件设计正确。

Rev Testing Meter of Plane's Main System Hydraulic Pressure Pump

In order to offer reference for periodic check of hydraulic pressure pump,the Rev testing meter of hydraulic pressure pump was designed.The hardware included four modules of single chip and liquid display module.The design of software included three modules of timer T0＇s interrupt service,counter T1＇s accumulation of pulse and the driving program of liquid display.On the basis of Proteus the simulation of the whole design is conducted with the help of simulated Hall pulse.
