【摘要】：为了提高电路信息实时采集的稳定性和可靠性,提出基于STC89C52单片机的电路信息实时采集系统设计方法。构造电路信息实时采集系统的总体结构模型,系统分为继电器模块、单片机控制模块、A/D采样电路模块、输出接口模块等。采用UART循环堆栈控制方法进行信号采样值幅度调整,对采集的实时信号通过放大滤波器输出至A/D转换器,采用单片机进行压控放大控制,输出高、低电压至继电器,实现实时采集信号的存储和放大输出。测试结果表明,信息实时采集系统具有较高的信号输出放大增益,信号输出的收敛性较好。
[Abstract]:In order to improve the stability and reliability of circuit information real-time acquisition, a design method of circuit information real-time acquisition system based on STC89C52 single chip microcomputer is presented. The overall structure model of the real-time circuit information acquisition system is constructed. The system is divided into relay module, MCU control module, A / D sampling circuit module, output interface module and so on. The UART cycle stack control method is used to adjust the amplitude of the signal sampling value. The real time signal is output to the A / D converter through amplifying filter, and the voltage control amplification control is carried out by single chip microcomputer, the output is high, low voltage to relay. The real-time acquisition signal can be stored and amplified. The test results show that the real-time information acquisition system has higher signal output amplification gain and better convergence of the signal output.
