智能傳感器

為了支持分布式的傳感器網(wǎng)絡(luò)，傳感器必須具備更強(qiáng)大的功能，而不只是收集數(shù)據(jù),盲目地發(fā)送數(shù)據(jù)給一個(gè)中央傳感器節(jié)點(diǎn). 跟傳統(tǒng)的傳感器相比，智能傳感器具有先進(jìn)的學(xué)習(xí)和適應(yīng)能力. 該系統(tǒng)還必須具有重構(gòu)的功能,并能進(jìn)行必要的數(shù)據(jù)處理，綜合來自不同傳感器的數(shù)據(jù)，驗(yàn)證來自本地和遠(yuǎn)程數(shù)據(jù).智能傳感器因此含有嵌入式處理器功能,這樣就可以提供計(jì)算資源，根據(jù)需要來執(zhí)行復(fù)雜的傳感和驅(qū)動(dòng)任務(wù)。

智能傳感器系統(tǒng)的功能,可以按照補(bǔ)償,信息處理,通訊和綜合來進(jìn)行描述. 各個(gè)部分的結(jié)合考慮到了智能傳感器需要工作在不同的的模式下而且可以自主測算的特點(diǎn)。

補(bǔ)償即系統(tǒng)通過自我診斷, 自校準(zhǔn)和適應(yīng)的方式偵測和響應(yīng)變化的網(wǎng)絡(luò)環(huán)境變化的能力. 智能傳感器必須能評估收集到的數(shù)據(jù), 把它同其他傳感器收集的信號相比較，確認(rèn)得到的數(shù)據(jù)的準(zhǔn)確性. 這個(gè)過程基本上涵蓋了傳感器配置階段. 信息處理包含了相關(guān)的數(shù)據(jù)處理,目的是要加強(qiáng)處理收集到的資料。

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.
