    • The present invention is a component monitoring system which includes all sensor and plant component monitoring at distributed plant locations close to the sensors which are the source of the signals to be analyzed. Minimally preconditioned analog sensor signals are multiplexed and further conditioned by a sensor signal preprocessor that adjusts the gain and filters the sensor signals before being applied to an analog-to-digital converter controlled by a data acquisition computer. The analog sensor signals are converted into digital samples and stored in a data memory of a digital signal processor using a direct memory access technique. The data acquisition computer also controls the selection of sensors, gain, etc., based on commands from a controller. The digital signal processor, once sufficient sensor data has been collected, performs appropriate processing using known digital signal processing techniques. This processed data is then sent to the controller for analysis to determine plant component condition. The analysis and processing routines can be changed by downloading a new routine from the controller. Once a sensor signal is processed, the controller selects the next sensor by transmitting an appropriate command to the data acquisition computer.
    • 本发明是一种组件监控系统,其包括在靠近传感器的分布式工厂位置处的所有传感器和设备部件监控,传感器是要分析的信号源。 微型预处理的模拟传感器信号被多路复用,并由传感器信号预处理器进一步调节,传感器信号预处理器在被应用于由数据采集计算机控制的模数转换器之前调节增益并对传感器信号进行滤波。 模拟传感器信号被转换成数字样本,并使用直接存储器访问技术存储在数字信号处理器的数据存储器中。 数据采集​​计算机还根据控制器的命令控制传感器,增益等的选择。 一旦已经收集足够的传感器数据,数字信号处理器就使用已知的数字信号处理技术进行适当的处​​理。 然后将该处理的数据发送到控制器进行分析以确定工厂组件状况。 可以通过从控制器下载新的例程来更改分析和处理程序。 一旦处理了传感器信号,控制器通过向数据采集计算机发送适当的命令来选择下一个传感器。
