摘要
设计了基于超声波衰减理论,以微控制器C8051F021为核心的矿浆浓度计的设计,并包含超声波发射电路、接收电路、功率放大电路、检波整形电路、LCD显示电路、485通信电路。另外通过软件滤波对数据进行适当处理,屏蔽掉噪声和干扰杂波信号、丰富的信息量实时的显示、并把测量的数据通过串口传输到PC中进行分析与比较。
This. design is based on the theory of ultrasonic attenuation, design of pulp concentration is C8051F021 microcontroller as the core of the meter, And contains the ultrasonic transmitting circuit, receiving circuit, the power amplification circuit, detection shaping circuit, LCD display circuit ,485 communication circuit. In addition to the da- ta processing by appropriate filtering software, shield the noise and clutter signal, the rich information of real-time display, and the measurement of data transmission in serial port to a PC through the analysis and comparison.
