彎板式動態軸重儀工作原理及特點

彎板式動態軸重衡采用了彎板技術，是由彎板式稱重傳感器、地感線圈、紅外線車輛分離器、輪胎識別器和數據處理中心等構成的動態軸重衡。它具有高準確度使用壽命長、對車輛行駛速度要求范圍較寬、安裝調試方便易行等特點，其稱量準確性可滿足我國交通部門高速公路計重收費的要求.
彎(wan)板(ban)(ban)(ban)式稱(cheng)(cheng)重(zhong)(zhong)技(ji)術于(yu)1968年在歐洲開始(shi)(shi)使用，國外(wai)(wai)彎(wan)板(ban)(ban)(ban)式稱(cheng)(cheng)重(zhong)(zhong)設備(bei)主(zhu)要(yao)用在車(che)速范圍(wei)為(wei)(0～200)km/h的(de)(de)動態超(chao)限檢測(ce)(ce)(ce)。經(jing)(jing)過(guo)軟件(jian)升級和設備(bei)國產(chan)(chan)化配套，從2003年開始(shi)(shi)，彎(wan)板(ban)(ban)(ban)式稱(cheng)(cheng)重(zhong)(zhong)設備(bei)在國內開始(shi)(shi)大規模地應用于(yu)高速或普通(tong)(tong)收(shou)費(fei)(fei)公路的(de)(de)計(ji)重(zhong)(zhong)收(shou)費(fei)(fei)。彎(wan)板(ban)(ban)(ban)式稱(cheng)(cheng)重(zhong)(zhong)設備(bei)用于(yu)計(ji)重(zhong)(zhong)收(shou)費(fei)(fei)的(de)(de)技(ji)術路線(xian)(xian)(xian)是(shi)：汲取國外(wai)(wai)技(ji)術，從車(che)輛(liang)寬速度(du)(du)范圍(wei)(0～200km/h)過(guo)渡，因此(ci)從技(ji)術原(yuan)理(li)及(ji)技(ji)術經(jing)(jing)驗上(shang)能(neng)較平穩地實現這種過(guo)渡，且長期(qi)使用的(de)(de)穩定(ding)性和可(ke)靠性好。彎(wan)板(ban)(ban)(ban)式稱(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)是(shi)一(yi)種彎(wan)板(ban)(ban)(ban)式動態軸(zhou)(zhou)重(zhong)(zhong)衡的(de)(de)工(gong)(gong)作原(yuan)理(li)是(shi)這樣(yang)的(de)(de)：承(cheng)(cheng)載器(qi)(qi)由(you)兩塊彎(wan)板(ban)(ban)(ban)式稱(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)組(zu)成，當車(che)軸(zhou)(zhou)行駛在承(cheng)(cheng)載器(qi)(qi)上(shang)時(shi)，傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)內部的(de)(de)電(dian)阻應變網產(chan)(chan)生一(yi)個與汽車(che)軸(zhou)(zhou)載成正比的(de)(de)模擬信號(hao)，并(bing)且輸(shu)出的(de)(de)周期(qi)與輪胎(tai)停留(liu)在傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)上(shang)的(de)(de)時(shi)間相同。每當一(yi)個輪胎(tai)經(jing)(jing)過(guo)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)時(shi)，傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)就會產(chan)(chan)生一(yi)個新的(de)(de)電(dian)子脈沖。這樣(yang)由(you)彎(wan)板(ban)(ban)(ban)式稱(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)完成車(che)軸(zhou)(zhou)的(de)(de)稱(cheng)(cheng)重(zhong)(zhong)、速度(du)(du)檢測(ce)(ce)(ce)、軸(zhou)(zhou)型判斷等工(gong)(gong)作。再(zai)由(you)紅(hong)外(wai)(wai)線(xian)(xian)(xian)車(che)輛(liang)分離器(qi)(qi)來(lai)(lai)進行車(che)輛(liang)的(de)(de)分離及(ji)提供開始(shi)(shi)、結束(shu)等信號(hao)。線(xian)(xian)(xian)圈來(lai)(lai)完成測(ce)(ce)(ce)速、倒車(che)的(de)(de)檢測(ce)(ce)(ce)，并(bing)與紅(hong)外(wai)(wai)線(xian)(xian)(xian)分離器(qi)(qi)一(yi)起(qi)對非(fei)車(che)輛(liang)以外(wai)(wai)的(de)(de)物體或人通(tong)(tong)過(guo)時(shi)的(de)(de)判斷，減少出錯。輪胎(tai)識別器(qi)(qi)主(zhu)要(yao)用來(lai)(lai)檢測(ce)(ce)(ce)通(tong)(tong)過(guo)車(che)輛(liang)每軸(zhou)(zhou)的(de)(de)輪胎(tai)數。上(shang)述信息全部由(you)數據采(cai)(cai)集器(qi)(qi)采(cai)(cai)集，并(bing)做預處理(li)輸(shu)入給(gei)中(zhong)央(yang)控制(zhi)單元(yuan)，由(you)中(zhong)央(yang)控制(zhi)單元(yuan)來(lai)(lai)處理(li)來(lai)(lai)自于(yu)各傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)的(de)(de)信號(hao)、計(ji)算(suan)(suan)數，把相關數據通(tong)(tong)過(guo)通(tong)(tong)訊方式送(song)給(gei)收(shou)費(fei)(fei)計(ji)算(suan)(suan)機(ji)。
