Sensors Plug&Play——智能传感器测量的新标准

Sensors Plug&Play-A New Standard for Automated Sensor Measurements

IEEE 14 5 1.4提出的一项传感器新标准减少了传感器配置的时间和难题。该标准创建了一个通用的方法 ,让传感器可以像计算机上USB鼠标一样即插即用。IEEE 14 5 1.4定义了一套通过模拟信号接口 ,向传感器加载自定义操作的机制。这个混合模式的接口把传统的模拟传感器信号与低成本的串行数字连接结合在一起 ,以访问传感器的内嵌的传感器电子数据表(TEDS)。为将“传感器即插即用”的优势延用于传统型模拟传感器 ,虚拟TEDS将以电子文档形式提供同样的传感器电子数据表。有了TEDS ,传感器就可以向与其连接的数据采集系统对自身进行自我识别和描述。

A new standard for sensors, proposed by IEEE 1451.4, reduces the time and challenges associated with sensor configuration. The standard establishes a universally accepted method of giving sensors plug and play capability, similar to the plug and play capability of a USB mouse and your computer. IEEE 1451.4 defines a mechanism for adding self describing behavior to sensors with an analog signal interface. This mixed mode interface combines the traditional analog sensor signal with a low cost serial digital link to access a transducer electronic data sheet (TEDS) embedded in the sensor. To extend the benefits of Sensors Plug&Play to traditional analog sensors, Virtual TEDS provides the same transducer electronic data sheet in electronic file format. With TEDS, the sensor identifies and describes itself to the data acquisition system to which it is connected.
