【摘要】 以单片机AT89C52为核心,借助于计算机串行通信技术,研制了一种智能化、网络化、微型化的智能流速采集仪。作为小型水电站数据采集系统中的远端流速采集和处理装置,经在江西洪门水电厂运行表明:设计的新型红外流速传感器能够克服环境光的影响,智能流速采集仪具有稳定性高、开发周期短、实时性好、体积小和灵活性强的特点,能够完成流速采集、处理、存储和显示,并可在2 km内与PC机串行通信,将采集到的流速值送至小型水电站数据采集系统。更多还原

【Abstract】 Research and facture of intelligent & network & micromation collection equipment for the velocity of flow by SCM and technology of serial communication.It is applied to collection equipment for the velocity of flow by the data collection system of the pint-sized water and electricity factory for long-distance apparatus.It circulated fine in the factory of the Hongming Water and electricity.The new-style sensor can conquer photic effect.It is provided with tranquilization and short exploitation cycle and finer real time and petite bulk and doughty agility.It accomplishes the velocity of flow collection and disposal and memory and display.The serial communication distance can be exceeding the remote place for 2 km with PC in the velocity of flow by the data collection system of the pint-sized water and electricity factory.更多还原
