摘　　要：利用低功耗、高性能的AVR单片机作为系统的数据处理主控单元,结合光照灵敏度较高的图像传感器和具有汉字显示的图形点阵液晶显示设备,对传统光学水准仪进行数字化改造,设计了硬件电路和软件编程,通过实验测试,提高了水准测量的精度。Using AVR MCU, a single -chip microcomputer with low power consumption and high performance, as the system＇s main control unit to process data, combining the image sensor with high sensitive illumination and geometric matrix liquid crystal display equipment, which can display Chinese characters, the traditional optical level has been digitally transformedand the hardwired connection and software programming have been designed. And after experiments and tests, the precision of leveling has been improved.
