電子式超載限製器的工作原理

    電子式超載限製器的工作原理：

    載荷傳感器是本裝置的檢測元件，載荷傳感器將載荷（起重量G）轉zhuan換huan為wei與yu其qi成cheng正zheng比bi的de電dian信xin號hao。目mu前qian
，載zai荷he限xian製zhi器qi中zhong使shi用yong的de載zai荷he限xian製zhi器qi主zhu要yao有you電dian阻zu應ying變bian式shi和he磁ci彈dan性xing式shi兩liang種zhong。用yong得de比bi較jiao多duo的de是shi電dian阻zu應ying變bian式shi。經jing載zai荷he傳chuan感gan器qi將jiang載zai荷he轉zhuan換huan成cheng電dian信xin號hao後hou
，通tong過guo放fang大da器qi將jiang信xin號hao放fang大da。放fang大da後hou的de信xin號hao一yi路lu經jingA/D變bian換huan器qi變bian換huan成cheng數shu字zi量liang，由you顯xian示shi器qi顯xian示shi重zhong量liang值zhi

，另ling一yi路lu送song入ru比bi較jiao器qi與yu預yu先xian設she定ding的de基ji準zhun信xin號hao進jin行xing比bi較jiao，不bu同tong的de基ji準zhun信xin號hao決jue定ding了le載zai荷he限xian製zhi器qi的de不bu同tong動dong作zuo點dian。比bi較jiao器qi的de基ji準zhun信xin號hao可ke設she定ding在zai起qi重zhong機ji額e定ding載zai荷he的de90%左zuo右you，為wei預yu報bao警jing值zhi，當dang起qi重zhong機ji起qi吊diao的de實shi際ji重zhong量liang大da於yu預yu報bao警jing值zhi時shi，比bi較jiao器qi輸shu出chu高gao電dian位wei，並bing驅qu動dong聲sheng光guang電dian路lu
，使shi其qi發fa出chu繼ji續xu聲sheng光guang信xin號hao，提ti醒xing司si機ji注zhu意yi起qi重zhong機ji已yi接jie近jin滿man負fu荷he。預yu報bao警jing信xin號hao不bu是shi必bi須xu的de，有you些xie載zai荷he限xian製zhi器qi中zhong沒mei有you設she預yu報bao警jing。比bi較jiao器qi的de基ji準zhun信xin號hao可ke設she定ding在zai額e定ding起qi重zhong量liang的de100%-110%之(zhi)間(jian)，當(dang)實(shi)際(ji)載(zai)荷(he)超(chao)過(guo)設(she)定(ding)值(zhi)時(shi)，比(bi)較(jiao)器(qi)輸(shu)出(chu)高(gao)電(dian)位(wei)，由(you)此(ci)觸(chu)發(fa)一(yi)個(ge)延(yan)時(shi)電(dian)路(lu)，經(jing)一(yi)定(ding)延(yan)時(shi)後(hou)由(you)門(men)電(dian)路(lu)輸(shu)出(chu)一(yi)個(ge)高(gao)電(dian)平(ping)驅(qu)動(dong)聲(sheng)光(guang)電(dian)路(lu)發(fa)出(chu)持(chi)續(xu)報(bao)警(jing)信(xin)號(hao)，與(yu)此(ci)同(tong)時(shi)，門(men)電(dian)路(lu)的(de)輸(shu)出(chu)高(gao)電(dian)平(ping)通(tong)過(guo)一(yi)個(ge)功(gong)率(lv)開(kai)關(guan)三(san)極(ji)管(guan)驅(qu)動(dong)繼(ji)電(dian)器(qi)動(dong)作(zuo)。繼(ji)電(dian)器(qi)的(de)一(yi)個(ge)觸(chu)頭(tou)串(chuan)接(jie)在(zai)起(qi)升(sheng)機(ji)械(xie)的(de)控(kong)製(zhi)線(xian)路(lu)中(zhong)
