Autonomous DAQ engine for evaluating sensor data

在德国发起了一个自治的数据访问recording system for industrial automation.

The MCM-216 data acquisition (DAQ) system functions autonomously and has 16 channels for feeding voltage values. Its sister model MCM-218 works with 8 inputs for recording analogue current values from 0 to 20 mA. Both models support a maximum sampling rate of 250 kS/s and are based around a 1.0 GHz ARM Cortex-A9 microcontroller.

Data recording in Industry 4.0 manufacturing environments is used for identifying and collecting important information, which is also necessary as a basis for management and controlling, energy-efficient use and the anticipatory servicing of automated systems. For this purpose, sensors record the desired condition and performance data for individual components and pass on corresponding signals, voltage or current to the DAQ module.

Converted to digital values by the MCM-216, the autonomous system can either trigger programmed actions directly on-site via digital and analogue outputs, or communicated digitally to the control system or to further autonomous devices. The direct recording of vibrations is a typical application to identify the formation of bearing defects in good time and therefore warn against possible subsequent damages, known as condition monitoring.

在较大的中央管理计算机架构中，记录和数字化可以例如通过诸如PXIE系统的多个DAQ插件卡进行，或者在信号发射机附近的边缘计算设备中处理处理。

两个设备都安装在127 x 111 x 40 mm工业铝壳中，无需额外的主机，通过两个千兆以太网接口集成在现有网络中。两个局域网插座允许多个设备在现场易于连接。由传感器记录的原始信号可以在本地直接过滤并在诸如FFT，电压，阵列或OA值之类的高值数据中编译。这样，可以在远程现场位置应用一个或多个设备作为独立测量系统。在转换后的和过滤的大小向下数据传输到中心位置的情况下，后端服务器的处理要求急剧减少。
