2016第八屆中國國際警(jing)用(yong)裝(zhuang)(zhuang)(zhuang)(zhuang)備博(bo)覽會(hui)于5月17日至20日在北(bei)京(jing)國家會(hui)議中心舉(ju)行(xing)，各類警(jing)用(yong)裝(zhuang)(zhuang)(zhuang)(zhuang)備齊聚亮相(xiang)。本屆展(zhan)(zhan)(zhan)會(hui)規模(mo)(mo)達40000平方米(mi)，參(can)(can)展(zhan)(zhan)(zhan)范圍囊(nang)括警(jing)用(yong)武(wu)器裝(zhuang)(zhuang)(zhuang)(zhuang)備、警(jing)用(yong)械具裝(zhuang)(zhuang)(zhuang)(zhuang)備、警(jing)用(yong)防護(hu)裝(zhuang)(zhuang)(zhuang)(zhuang)備、警(jing)用(yong)交(jiao)通(tong)工具、警(jing)用(yong)通(tong)訊裝(zhuang)(zhuang)(zhuang)(zhuang)備等，無論(lun)是(shi)展(zhan)(zhan)(zhan)會(hui)規模(mo)(mo)、參(can)(can)展(zhan)(zhan)(zhan)商還是(shi)觀展(zhan)(zhan)(zhan)人數都將再創新高！

據說(shuo)今(jin)年的展(zhan)會(hui)安保升級，普(pu)通觀眾想要進(jin)入一(yi)睹風采著實不易(yi)。在展(zhan)會(hui)現場，除槍棍(gun)等(deng)“傳(chuan)統”裝備外，便攜式機器人(ren)、警(jing)用智能眼鏡等(deng)高科(ke)技警(jing)用裝備紛紛亮相。而作為警(jing)用新型裝備之一(yi)的無(wu)人(ren)機，是本次警(jing)博會(hui)的又一(yi)大亮點，多(duo)款多(duo)旋翼、固定翼無(wu)人(ren)機集中(zhong)亮相。

警用無人(ren)(ren)機(ji)(ji)(ji)(ji)屬于(yu)專(zhuan)業級無人(ren)(ren)機(ji)(ji)(ji)(ji)，相比(bi)完成航拍(pai)等(deng)用途的消費級無人(ren)(ren)機(ji)(ji)(ji)(ji)，專(zhuan)業級無人(ren)(ren)機(ji)(ji)(ji)(ji)在續航時間、載重量、安全(quan)可(ke)靠(kao)性等(deng)方(fang)面要求(qiu)更高。專(zhuan)業級無人(ren)(ren)機(ji)(ji)(ji)(ji)還(huan)具有定(ding)制化(hua)的特(te)點，無人(ren)(ren)機(ji)(ji)(ji)(ji)只是一個(ge)平臺，搭(da)載不(bu)同(tong)設備可(ke)以實現不(bu)同(tong)的功能，如警用無人(ren)(ren)機(ji)(ji)(ji)(ji)常(chang)常(chang)搭(da)載空中(zhong)喊話、投(tou)放催淚瓦斯、安防(fang)監控等(deng)裝置。

從未來發展(zhan)來看(kan)，警(jing)(jing)用無人(ren)(ren)機(ji)(ji)的(de)(de)應用將會(hui)更(geng)(geng)(geng)加(jia)普及，將形(xing)成以(yi)警(jing)(jing)用直升機(ji)(ji)與(yu)無人(ren)(ren)機(ji)(ji)配合(he)為主(zhu)，并根(gen)據特定環境輔以(yi)固(gu)定翼飛機(ji)(ji)及動力傘(san)等(deng)(deng)航(hang)空設(she)備(bei)的(de)(de)警(jing)(jing)用空中力量。與(yu)直升機(ji)(ji)相比，警(jing)(jing)用無人(ren)(ren)機(ji)(ji)更(geng)(geng)(geng)加(jia)靈(ling)活、高效，且(qie)操作相對簡單。同(tong)時，其(qi)人(ren)(ren)才培養、飛行器采購、設(she)備(bei)維護保(bao)養等(deng)(deng)方(fang)(fang)面的(de)(de)成本大大降低。由于其(qi)體積小，行動靈(ling)活，更(geng)(geng)(geng)適(shi)合(he)在城市樓(lou)宇間飛行。因(yin)為載荷、航(hang)程等(deng)(deng)方(fang)(fang)面有(you)著自身的(de)(de)特點，其(qi)更(geng)(geng)(geng)適(shi)合(he)偵察、預警(jing)(jing)、巡邏、監控等(deng)(deng)飛行作業，并且(qie)能(neng)夠(gou)與(yu)警(jing)(jing)用直升機(ji)(ji)形(xing)成有(you)效互補。

根據早些時候的報道，全國(guo)有25個(ge)省份配(pei)備了300多(duo)架警(jing)(jing)用(yong)無(wu)(wu)人(ren)(ren)機(ji)(ji)(ji)(ji)，其中80%是2014年以來(lai)配(pei)備的。面對無(wu)(wu)人(ren)(ren)機(ji)(ji)(ji)(ji)警(jing)(jing)務(wu)應用(yong)的巨(ju)大(da)市(shi)場(chang)，許多(duo)無(wu)(wu)人(ren)(ren)機(ji)(ji)(ji)(ji)企(qi)業(ye)(ye)加大(da)了警(jing)(jing)用(yong)無(wu)(wu)人(ren)(ren)機(ji)(ji)(ji)(ji)的研發。在2015年的高交會(hui)上，過半數(shu)的無(wu)(wu)人(ren)(ren)機(ji)(ji)(ji)(ji)參展(zhan)企(qi)業(ye)(ye)展(zhan)示了警(jing)(jing)用(yong)無(wu)(wu)人(ren)(ren)機(ji)(ji)(ji)(ji)產品(pin)。而在本(ben)屆警(jing)(jing)用(yong)裝備博覽會(hui)上，易瓦特、艾特航空、一電(dian)科技等國(guo)內知名(ming)企(qi)業(ye)(ye)攜其警(jing)(jing)用(yong)無(wu)(wu)人(ren)(ren)機(ji)(ji)(ji)(ji)產品(pin)到(dao)會(hui)參展(zhan)。

目前這些警用無人機在動力能源上以使用無人機電池為主，每一個飛(fei)手都清楚(chu)，動力電(dian)(dian)池孜(zi)孜(zi)不倦(juan)地為電(dian)(dian)機、電(dian)(dian)調、飛(fei)控、OSD、圖傳、接(jie)收機、遙控器、監視(shi)器等飛(fei)行器的(de)各(ge)個用(yong)電(dian)(dian)部(bu)件(jian)提供電(dian)(dian)力保(bao)障(zhang)。為了(le)更好(hao)的(de)、更安全的(de)飛(fei)行，作為飛(fei)手就(jiu)要去了(le)解(jie)電(dian)(dian)池的(de)參數、使用(yong)、保(bao)養、充放(fang)電(dian)(dian)等，這樣(yang)才能保(bao)障(zhang)每次安防任務的(de)順利進(jin)行。

現在無人機上用的鋰電池為“鋰聚合物電池”，一般簡稱(cheng)為鋰電(dian)(dian)(dian)。鋰聚合物電(dian)(dian)(dian)池(chi)具有能量(liang)(liang)(liang)密(mi)度高(gao)、更小(xiao)型化(hua)、超薄化(hua)、輕量(liang)(liang)(liang)化(hua)，以(yi)及高(gao)安全性(xing)等多(duo)種明(ming)顯優勢(shi)。選一塊電(dian)(dian)(dian)池(chi)主要看電(dian)(dian)(dian)池(chi)的(de)基(ji)本參數，比如一塊22.2V 10000mAh的(de)TATTU無人機電(dian)(dian)(dian)池(chi)，它(ta)是(shi)由6片(pian)額定電(dian)(dian)(dian)壓為3.7V、容(rong)量(liang)(liang)(liang)10000mAh鋰電(dian)(dian)(dian)芯串(chuan)聯而成，即(ji)常說的(de)6S1P。鋰電(dian)(dian)(dian)中，單片(pian)電(dian)(dian)(dian)芯電(dian)(dian)(dian)壓3.7 V是(shi)額定電(dian)(dian)(dian)壓，單片(pian)鋰電(dian)(dian)(dian)芯的(de)實(shi)際電(dian)(dian)(dian)壓為2.75~4.2 V，鋰電(dian)(dian)(dian)上標的(de)電(dian)(dian)(dian)容(rong)量(liang)(liang)(liang)是(shi)4.2 V放電(dian)(dian)(dian)至2.75V所獲得的(de)電(dian)(dian)(dian)量(liang)(liang)(liang)。鋰電(dian)(dian)(dian)必須保持在2.75~4.2V這個電(dian)(dian)(dian)壓范圍內使(shi)用(yong)。

如電(dian)(dian)(dian)壓低于(yu)(yu)2.75V則屬于(yu)(yu)過度放電(dian)(dian)(dian)，鋰(li)電(dian)(dian)(dian)會(hui)膨脹(zhang)，內部的化學(xue)液體會(hui)結晶，這些(xie)結晶有可能會(hui)刺穿內部結構層造成(cheng)(cheng)短路(lu)，甚至會(hui)讓(rang)鋰(li)電(dian)(dian)(dian)電(dian)(dian)(dian)壓變為零。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時單片(pian)電(dian)(dian)(dian)壓高于(yu)(yu)4.2V屬于(yu)(yu)過度充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，內部化學(xue)反應過于(yu)(yu)激烈(lie)，鋰(li)電(dian)(dian)(dian)會(hui)鼓氣膨脹(zhang)，若繼(ji)續(xu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)會(hui)膨脹(zhang)、燃(ran)燒。所以一定要(yao)用符合安全標準的正規充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)對(dui)電(dian)(dian)(dian)池進行充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，同時嚴(yan)禁對(dui)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)進行私(si)自改裝，這可能會(hui)造成(cheng)(cheng)很(hen)嚴(yan)重(zhong)的后果!

還要提示(shi)一點(dian)，切記——不(bu)(bu)能(neng)將(jiang)動(dong)力電(dian)池單片電(dian)芯電(dian)壓用到2.75V，此時電(dian)池已不(bu)(bu)能(neng)提供給飛機(ji)有效電(dian)力進行(xing)飛行(xing)，盡可能(neng)避免因電(dian)池電(dian)壓不(bu)(bu)足導致炸機(ji)。

針(zhen)對無人機行(xing)(xing)業(ye)應用(yong)，TATTU電池可在影視航拍、農業(ye)植(zhi)保、地質勘測、 森林防(fang)火(huo)、抗洪搶險、環境監測等(deng)領(ling)域廣泛應用(yong)，相信可以給很多用(yong)戶帶來不一樣的(de)飛行(xing)(xing)體驗。
