    摘要:

    針對溫室內(nèi)環(huán)境信息變化緩慢、冗余度大和時(shí)間空間相關(guān)性強(qiáng)的特點(diǎn)，提出了基于事件驅(qū)動與支持度融合的溫室環(huán)境監(jiān)測無線傳感器網(wǎng)絡(luò)(WSN)的節(jié)能傳輸模型。利用所建立的數(shù)據(jù)節(jié)能傳輸模型進(jìn)行了溫室環(huán)境試驗(yàn)，結(jié)果表明采用基于事件驅(qū)動的數(shù)據(jù)傳輸模型能夠減少83.8%數(shù)據(jù)傳輸次數(shù),，基于支持度函數(shù)的數(shù)據(jù)融合能夠根據(jù)數(shù)據(jù)之間的關(guān)聯(lián)程度計(jì)算出各原始數(shù)據(jù)的加權(quán)值,，融合效果優(yōu)于算術(shù)平均值,。

    Abstract:

    Since environmental information in greenhouse had the characteristics of slow changing, great redundancy, and strong spatial and temporal correlation, a energy transmission model of wireless sensor network (WSN) was proposed based on event-driven and data fusion for the acquisition of environmental information in greenhouse. With the energy transmission model the field test was conducted. The results showed that the data transmission model based on event-driven could reduce the data transmission frequency 83.8%. The data fusion based on data support function could calculate each weighted value of the original data size according to the degree of association among the data, and was better than the arithmetic mean.
