航空蓄电池作为飞机的备用电源,其性能状况将直接影响到飞行的安全。因此,对航空蓄电池的性能参数必须经常地、定期地检测和计算。目前检测的数据都是通过航空蓄电池计算尺计算或笔算,计算方法繁琐、精度低,为了确保飞行安全,实现航空蓄电池性能检测计算的电子化、数字化,我们研制了航空蓄电池计算器。一、硬件组成 CPU采用AT89C51,不仅省去了锁存器、程序存储器等芯片,而且功耗大大降低。显示器采用16×2字符点阵液晶显示器,显示信息量大、省电。键盘采用中断输入法,与软件配合实
As an aircraft backup power battery, its performance status will directly affect the flight safety. Therefore, the performance parameters of the aviation battery must be regularly and regularly detected and calculated. At present, the test data are calculated by air battery ruler or pen calculation, the calculation method is tedious and the accuracy is low. In order to ensure flight safety and realize the electronic and digitization of aviation battery performance detection and calculation, we have developed the aircraft battery calculator. First, the hardware components CPU using AT89C51, not only eliminates the need for latches, program memory and other chips, and greatly reduce power consumption. Display with 16 × 2 character dot matrix liquid crystal display, showing a large amount of information, power saving. Keyboard interrupt input method, and the software with real
