| 摘 要： | 普通的模拟量隔离方法很难实现高精度的信号采集。介绍一种新颖的模拟信号采集及隔离方法,该方法采用普通光耦(TIL113)和软件程序补偿的方式来消除光耦非线性,实现了精度较高的模拟信号采集及处理。该方法已成功应用于嵌入式计算机控制系统的模拟信号采集电路中。

| Abstract: | The normal simulation insulation method is difficult to collect the high accuracy signals.The paper introduced a new simulated signal collection and the insulation method.The method can apply the normal optical coupling(TIL113) and the software compensation method to eliminate the non-linear of the optical coupling.The method can collect and handle the high accuracy simulated signals.The method has been successfully applied to the simulated signal collected circuit of the control system for the inserted computer. |
