4日，記(ji)者(zhe)從中科院青藏高原(yuan)研(yan)究(jiu)所獲悉，該所研(yan)究(jiu)人員利用自主研(yan)發的無(wu)人機物(wu)(wu)聯(lian)網(wang)(wang)中繼(ji)系統，實(shi)現無(wu)公網(wang)(wang)覆蓋偏(pian)遠地區(qu)實(shi)時數(shu)據采(cai)集。這表明(ming)該無(wu)人機物(wu)(wu)聯(lian)網(wang)(wang)中繼(ji)系統可用于(yu)采(cai)集青藏高原(yuan)等偏(pian)遠區(qu)環境監測設(she)備數(shu)據。相關研(yan)究(jiu)成果發表于(yu)國際物(wu)(wu)聯(lian)網(wang)(wang)領域頂級期刊(kan)《電氣與電子工程師學會·物(wu)(wu)聯(lian)網(wang)(wang)》。

青藏高原幅員遼闊，地(di)(di)(di)形(xing)復雜，很多區域沒有被移動蜂窩網(wang)絡覆蓋(gai)，生(sheng)態(tai)環境監(jian)測數(shu)據要靠人(ren)(ren)(ren)工(gong)采集。針(zhen)對這一問題(ti)，研(yan)究人(ren)(ren)(ren)員研(yan)發(fa)了(le)面向生(sheng)態(tai)監(jian)測物聯(lian)網(wang)的無人(ren)(ren)(ren)機(ji)(ji)中(zhong)繼系統(tong)。論文第一作者，中(zhong)科院(yuan)西北生(sheng)態(tai)環境資源研(yan)究院(yuan)博士生(sheng)張明虎介紹，該系統(tong)包括(kuo)無人(ren)(ren)(ren)機(ji)(ji)機(ji)(ji)載中(zhong)繼設(she)備、地(di)(di)(di)面物聯(lian)網(wang)終(zhong)端(duan)(duan)設(she)備。在無公(gong)網(wang)覆蓋(gai)的偏遠(yuan)地(di)(di)(di)區，無人(ren)(ren)(ren)機(ji)(ji)攜帶中(zhong)繼設(she)備飛至(zhi)地(di)(di)(di)面終(zhong)端(duan)(duan)附近(jin)區域時，無人(ren)(ren)(ren)機(ji)(ji)中(zhong)繼設(she)備與地(di)(di)(di)面終(zhong)端(duan)(duan)建立遠(yuan)距離無線(xian)電通(tong)信鏈路并(bing)發(fa)送喚醒(xing)命(ming)令，喚醒(xing)地(di)(di)(di)面終(zhong)端(duan)(duan)上的無線(xian)通(tong)信模塊。當無人(ren)(ren)(ren)機(ji)(ji)飛至(zhi)地(di)(di)(di)面終(zhong)端(duan)(duan)上空(kong)時，無人(ren)(ren)(ren)機(ji)(ji)中(zhong)繼設(she)備與地(di)(di)(di)面終(zhong)端(duan)(duan)建立高速數(shu)據傳(chuan)輸鏈路。地(di)(di)(di)面智能終(zhong)端(duan)(duan)將存儲的環境監(jian)測數(shu)據發(fa)送至(zhi)無人(ren)(ren)(ren)機(ji)(ji)。收集數(shu)據后，無人(ren)(ren)(ren)機(ji)(ji)飛至(zhi)有公(gong)網(wang)覆蓋(gai)的區域轉發(fa)已采集數(shu)據至(zhi)公(gong)網(wang)。

論(lun)文通訊作者、中科院(yuan)青藏(zang)高原研究所研究員李新表示，該系統可兼容大多數(shu)環境監測(ce)設備，優化傳統人(ren)工采集數(shu)據人(ren)力(li)成(cheng)本高的劣勢。遠(yuan)程喚醒功能(neng)極大地(di)降低(di)了野外部署設備功耗，保(bao)證了監測(ce)設備長期(qi)穩定(ding)運行(xing)。對在(zai)青藏(zang)高原等無公網覆蓋的偏(pian)遠(yuan)地(di)區或極端區域，開展環境監測(ce)和(he)收集監測(ce)數(shu)據具有重要意義。
