激光多普勒测速信号微机处理系统

Computer System to Process Laser Doppler Speed-measuring signals

采用微处理机作为硬件核心，在所编软件程序的支持下，用软件程序代替了传统方法中相当数量电子电路的硬件功能．这样，简化了电路，降低了成本，而且系统在计数数据的可靠性、测速的精度以及数据处理、自动化操作方面都比原系统优化．

ith adopted a micro-processing unit(MPU) as the main hardware andsupported by the matching edited software, this software can take the place offunctions of quite a few electric circuits. So in the system the circuits are simplifiedand the production cost is reduced. In the aspects of reliability, precision, dataprocessing and automatic operation, this system is superior to the former ones
