電(dian)子(zi)地磅(bang)防(fang)作弊的手段有哪(na)些
很早以前(qian)，大家都在(zai)用(yong)機械式(shi)地磅，那(nei)(nei)樣的作(zuo)弊(bi)手段(duan)無非(fei)就那(nei)(nei)么的幾種(zhong)，隨著科技的進(jin)步，高科技的產品不段(duan)的出現，電子(zi)地磅也到(dao)市場上很長一段(duan)時間(jian)了，電子(zi)地磅作(zuo)弊(bi)手段(duan)越來(lai)越高明，總結(jie)出來(lai)有以下三(san)點(dian)，供大家參考：

二、地磅干擾設備
“地磅干擾(rao)設備(bei)"實(shi)際(ji)上就(jiu)是“磁(ci)(ci)場發(fa)射設各(ge)(ge)"，一(yi)般(ban)用(yong)手持地磅干擾(rao)設備(bei)的方式直接對(dui)電(dian)子(zi)地磅或顯(xian)(xian)示(shi)儀表(biao)施加外接電(dian)磁(ci)(ci)信一(yi)號，在(zai)磁(ci)(ci)場的作用(yong)下電(dian)子(zi)地磅或顯(xian)(xian)示(shi)儀表(biao)內的電(dian)流發(fa)生變化，從而(er)使電(dian)子(zi)地磅儀表(biao)顯(xian)(xian)示(shi)發(fa)生改(gai)變。“地磅干擾(rao)設各(ge)(ge)"形(xing)狀各(ge)(ge)式各(ge)(ge)樣，磁(ci)(ci)場強度與所配電(dian)池能量成正(zheng)比。
目前在新疆或其他地方棉花(hua)行業已發現多起地榜(bang)干(gan)擾(rao)設(she)各近距離(li)發射(she)磁場干(gan)擾(rao)電子地磅顯示儀表重(zhong)量數字的案件。
用地磅干(gan)(gan)擾設備(bei)對(dui)顯示(shi)(shi)儀(yi)表(biao)(biao)(biao)作弊:作案人將手機改(gai)裝成地磅干(gan)(gan)擾設備(bei)，近距離靠(kao)近顯示(shi)(shi)儀(yi)表(biao)(biao)(biao)，在(zai)稱重(zhong)時直接對(dui)顯示(shi)(shi)儀(yi)表(biao)(biao)(biao)發射強磁場信號，而上海“耀華"牌顯示(shi)(shi)儀(yi)表(biao)(biao)(biao)是作案者針(zhen)對(dui)的(de)(de)主要對(dui)象。經對(dui)“耀華"牌顯示(shi)(shi)儀(yi)表(biao)(biao)(biao)電(dian)路的(de)(de)分析(xi)，該儀(yi)表(biao)(biao)(biao)的(de)(de)設計存在(zai)先天的(de)(de)缺陷(xian)“儀(yi)表(biao)(biao)(biao)內的(de)(de)一(yi)個芯(xin)片極易遭受外界磁場的(de)(de)干(gan)(gan)擾，并能(neng)在(zai)一(yi)定強度(du)磁場作用下顯示(shi)(shi)數據發生變化，根據磁場力線方向的(de)(de)不同，顯示(shi)(shi)數據增(zeng)加(jia)(增(zeng)加(jia)毛重(zhong))或減(jian)少(shao)(shao)(減(jian)少(shao)(shao)皮(pi)重(zhong))。該儀(yi)表(biao)(biao)(biao)外殼是非金屬(shu)的(de)(de)，搞磁場干(gan)(gan)擾的(de)(de)性能(neng)遠(yuan)不如其他顯示(shi)(shi)儀(yi)表(biao)(biao)(biao)。可用無線對(dui)講(jiang)對(dui)其進行近距離的(de)(de)試驗來難驗證(zheng)。
用(yong)地(di)(di)磅干擾設備對棉花(hua)衣分(fen)電(dian)子(zi)秤作(zuo)弊(bi):有的(de)作(zuo)案人用(yong)地(di)(di)磅干擾設備對棉花(hua)衣分(fen)電(dian)子(zi)稱(cheng)進行作(zuo)案。棉花(hua)衣分(fen)稱(cheng)實際也是(shi)一種小電(dian)子(zi)稱(cheng)，穩重(zhong)數量(liang)小.民(min)度高，較小的(de)磁場就可能使稱(cheng)重(zhong)數量(liang)發生改變。用(yong)地(di)(di)磅干擾設備提高棉花(hua)衣分(fen)值(zhi)的(de)辦法同樣(yang)能達(da)到獲取(qu)非法利潤的(de)目的(de)。
三、有線遙(yao)控
有線遙(yao)(yao)控(kong)設(she)(she)(she)(she)(she)備(bei)(bei)(bei)有兩個裝置(zhi)組(zu)成:手(shou)持小遙(yao)(yao)控(kong)設(she)(she)(she)(she)(she)備(bei)(bei)(bei)和解(jie)(jie)碼設(she)(she)(she)(she)(she)備(bei)(bei)(bei)。手(shou)持小遙(yao)(yao)控(kong)設(she)(she)(she)(she)(she)備(bei)(bei)(bei)由(you)(you)生(sheng)產)-家(jia)生(sheng)產，出)’時已標明頻(pin)率、編碼等技術指標。解(jie)(jie)碼設(she)(she)(she)(she)(she)備(bei)(bei)(bei)內(nei)的設(she)(she)(she)(she)(she)備(bei)(bei)(bei)件在內(nei)地(di)(di)(di)電(dian)(dian)設(she)(she)(she)(she)(she)備(bei)(bei)(bei)元件市場上(shang)可(ke)以(yi)購買(mai)到，解(jie)(jie)碼設(she)(she)(she)(she)(she)備(bei)(bei)(bei)一般由(you)(you)不法商人購買(mai)元設(she)(she)(she)(she)(she)備(bei)(bei)(bei)件同后自制(zhi)。解(jie)(jie)碼設(she)(she)(she)(she)(she)備(bei)(bei)(bei)部(bu)分一般安裝在電(dian)(dian)子(zi)地(di)(di)(di)磅(bang)(bang)傳感設(she)(she)(she)(she)(she)備(bei)(bei)(bei)進出線上(shang)，小型(xing)或微型(xing)解(jie)(jie)碼設(she)(she)(she)(she)(she)備(bei)(bei)(bei)可(ke)以(yi)安裝在地(di)(di)(di)磅(bang)(bang)顯示(shi)儀(yi)表(biao)內(nei)，因(yin)為須事先和稱體連接安裝，所以(yi)稱其為有線遙(yao)(yao)控(kong)設(she)(she)(she)(she)(she)備(bei)(bei)(bei)。但手(shou)持小遙(yao)(yao)控(kong)設(she)(she)(she)(she)(she)備(bei)(bei)(bei)和解(jie)(jie)碼設(she)(she)(she)(she)(she)備(bei)(bei)(bei)之間(jian)的仍是(shi)無線方(fang)式。通過手(shou)持小遙(yao)(yao)控(kong)設(she)(she)(she)(she)(she)備(bei)(bei)(bei)遠端(duan)曲線控(kong)制(zhi)解(jie)(jie)碼設(she)(she)(she)(she)(she)備(bei)(bei)(bei)工作，遙(yao)(yao)控(kong)設(she)(she)(she)(she)(she)備(bei)(bei)(bei)與電(dian)(dian)子(zi)地(di)(di)(di)磅(bang)(bang)傳感設(she)(she)(she)(she)(she)備(bei)(bei)(bei)或地(di)(di)(di)磅(bang)(bang)儀(yi)表(biao)相(xiang)連的解(jie)(jie)碼設(she)(she)(she)(she)(she)備(bei)(bei)(bei)的電(dian)(dian)阻、電(dian)(dian)橋電(dian)(dian)位發生(sheng)改變，達到改變電(dian)(dian)子(zi)地(di)(di)(di)磅(bang)(bang)顯示(shi)儀(yi)表(biao)稱重(zhong)數字的目(mu)的。
有線(xian)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)有三個特點(dian):一(yi)是(shi)手(shou)持小遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)、解碼(ma)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)的(de)(de)(de)(de)工作(zuo)頻率在(zai)300-6(X)M HZ，如(ru)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)車鎖、遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)電(dian)動(dong)門的(de)(de)(de)(de)應用(yong)(yong)等;二是(shi)手(shou)持小遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)和(he)解碼(ma)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)必(bi)須配對使(shi)(shi)用(yong)(yong)，缺(que)(que)一(yi)無效;三是(shi)手(shou)持遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)內的(de)(de)(de)(de)編(bian)碼(ma)必(bi)須與解碼(ma)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)內編(bian)碼(ma)*一(yi)致時(shi)(shi)(shi)，才(cai)‘能實現手(shou)持小遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)遠端(duan)(duan)控(kong)(kong)(kong)(kong)制解碼(ma)設(she)(she)(she)各工作(zuo)。解碼(ma)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)電(dian)源一(yi)般(ban)取白電(dian)子(zi)地(di)(di)磅(bang)本身(shen)的(de)(de)(de)(de)電(dian)源，也(ye)有接電(dian)池(chi)(chi)和(he)電(dian)瓶供(gong)電(dian)的(de)(de)(de)(de)，外接電(dian)池(chi)(chi)和(he)電(dian)瓶在(zai)無電(dian)時(shi)(shi)(shi)儀(yi)(yi)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)顯示就(jiu)會不(bu)正(zheng)常，新(xin)疆(jiang)多起地(di)(di)磅(bang)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)案件就(jiu)是(shi)由于外接電(dian)池(chi)(chi)和(he)電(dian)瓶缺(que)(que)點(dian)粕儀(yi)(yi)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)顯示不(bu)正(zheng)常才(cai)得以(yi)發現。手(shou)持小遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)至少為兩按(an)鍵(jian)式，對應電(dian)子(zi)地(di)(di)磅(bang)產生的(de)(de)(de)(de)結果(guo)是(shi)地(di)(di)磅(bang)儀(yi)(yi)表重(zhong)(zhong)量(liang)(liang)(liang)變化和(he)復位(wei)(回(hui)零(ling))。可預(yu)先通過高速(su)電(dian)阻值設(she)(she)(she)定遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)數(shu)量(liang)(liang)(liang)，遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)的(de)(de)(de)(de)數(shu)量(liang)(liang)(liang)比較穩(wen)定。在(zai)使(shi)(shi)用(yong)(yong)中，手(shou)持小遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)各至少要按(an)兩次:增(zeng)加或(huo)減(jian)少重(zhong)(zhong)量(liang)(liang)(liang)時(shi)(shi)(shi)按(an)一(yi)次“變量(liang)(liang)(liang)"鍵(jian)，稱重(zhong)(zhong)物體(ti)離開電(dian)子(zi)地(di)(di)磅(bang)時(shi)(shi)(shi)，再按(an)一(yi)次“復位(wei)(回(hui)零(ling)"鍵(jian)“，且(qie)按(an)"復位(wei)(回(hui)零(ling))“鍵(jian)時(shi)(shi)(shi)必(bi)須和(he)稱重(zhong)(zhong)物體(ti)離開地(di)(di)磅(bang)同時(shi)(shi)(shi)進行，否則，遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)增(zeng)加或(huo)減(jian)少的(de)(de)(de)(de)重(zhong)(zhong)量(liang)(liang)(liang)就(jiu)會在(zai)顯示設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)上(shang)。手(shou)持小遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)遠端(duan)(duan)控(kong)(kong)(kong)(kong)制解碼(ma)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)的(de)(de)(de)(de)距(ju)離一(yi)般(ban)在(zai)50米以(yi)內，若(ruo)手(shou)持遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)設(she)(she)(she)備(bei)(bei)(bei)(bei)(bei)(bei)用(yong)(yong)的(de)(de)(de)(de)電(dian)池(chi)(chi)多，遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)距(ju)離可達到數(shu)百米遠。
