自动检测设备模入信号故障及分析处理

有些传感器在工作时输出的电压信号就是属于模拟信号,模入信号的采集流程为:模入信号→放大板(对模拟信号进行放大)→A/D调理板→A/D采集板→控制系统软件采集。在传输过程中模入信号故障常见现象有带放大板的模拟信号故障和不带放大板的模拟信号故障两种,文中对如何对此故障进行处理提出了分析方法。

The Analysis and Management to the Analog Signal Malfunction of Automatic Detection Equipment

A certain kind of sensor in the voltage signal output is belonged to the analog signal, of which the collection process is ： analog sigual→amplifieation hoard （amplified analog signal） →A/D regulation board→A/D collection board→controlling system software collection. The eommon phenomenon of the analog signal malfunction during the transmission is ： the analog signal malfunction with the amplification board and those without the latter one. The analysis methods to the management of its malfunction were brought forward.
