智能传感器

为了支持分布式的传感器网络，传感器必须具备更强大的功能，而不只是收集数据,盲目地发送数据给一个中央传感器节点. 跟传统的传感器相比，智能传感器具有先进的学习和适应能力. 该系统还必须具有重构的功能,并能进行必要的数据处理，综合来自不同传感器的数据，验证来自本地和远程数据.智能传感器因此含有嵌入式处理器功能,这样就可以提供计算资源，根据需要来执行复杂的传感和驱动任务。

智能传感器系统的功能,可以按照补偿,信息处理,通讯和综合来进行描述. 各个部分的结合考虑到了智能传感器需要工作在不同的的模式下而且可以自主测算的特点。

补偿即系统通过自我诊断, 自校准和适应的方式侦测和响应变化的网络环境变化的能力. 智能传感器必须能评估收集到的数据, 把它同其他传感器收集的信号相比较，确认得到的数据的准确性. 这个过程基本上涵盖了传感器配置阶段. 信息处理包含了相关的数据处理,目的是要加强处理收集到的资料。

Intelligent Sensors
Background
To support the requirements of distributed sensor networks, sensors must possess greater functionality than simply gathering data and blindly transmitting the data to a centralized sensor node. Intelligent sensors are an extension of traditional sensors to those with advanced learning and adaptation capabilities. The system must also be re-configurable and perform the necessary data interpretation, fusion of data from multiple sensors and the validation of local and remotely collected data. Intelligent sensors therefore contain embedded processing functionality that provides the computational resources to perform complex sensing and actuating tasks along with high level applications.
The functions of an intelligent sensor system can be described in terms of compensation, information processing, communications and integration. The combination of these respective elements allow for the development of intelligent sensors that can operate in a multi-modal fashion as well conducting active autonomous sensing.
