Gwaro iri nderereferensi chete uye harinangi chero mhando kana chigadzirwa.
Kuongorora mashandiro eakasiyana-siyana ekuchera ekudzora mayuniti (akadai seECU, EECU, uye IECU), kuongororwa kunogona kuitwa kuburikidza neakawanda mamiriro, kusanganisira chaiyo mashandiro ekuita, mhinduro yekukanganisa, uye kuchinjika kwezvakatipoteredza. Yakasanganiswa nemakesi chaiwo emhando dzemhando dzakaita seKomatsu, Caterpillar, SANY, neVolvo, zvikamu zvinotevera zvinotsanangura nzira yekusiyanisa pakati pemhando yepamusoro uye yakaderera-mhando yekudzora mayuniti kubva pamaonero ekuita, kuongororwa kukanganisa, uye kuchinjika kwezvakatipoteredza, iine simba rinoshanda kushanda:
Caterpillar 320D: Musiyano Wekushanda Pakati peMabhodhi Epamusoro-Yepamusoro uye Yakaderera-Unhu (Mayuniti Ekudzora)
Nyaya 1: High-Quality Control Unit
Muchirongwa chikuru chepasi, Caterpillar 320D excavator yakashongedzerwa neyekutanga michina yekugadzira (OEM) yedunhu bhodhi inogona kunyatsoenderana nemamiriro akasiyana ekushanda. Paunenge uchishanda muvhu rakapfava, iyo control unit yakaona kushomeka kwekuchera kuburikidza nema sensors uye otomatiki kuchinjika kune yakaderera-simba ehupfumi modhi, kuderedza kushandiswa kwemafuta ne15% zvichienzaniswa nemimwe michina yekirasi imwechete. Pamabasa ekuchera uye anopwanya matombo, yakakurumidza kuwedzera injini yekubuda, zvichiita kuti uwandu hwekushanda hwakagadzikana hunosvika 200-300 cubic metres paawa-10% -20% inoshanda kupfuura zvigadzirwa zvemhando imwe chete.
Pamusoro pezvo, panguva yekuvaka mugero wepasi pevhu, iyo control unit yakaona kukwira kusingaite kwemafuta ehydraulic tembiricha uye pakarepo yakaridza alarm pachiratidziro. Vashandi vekuchengetedza vakakurumidza kuchenesa marara kubva kune radiator zvichienderana neyambiro iyi, kudzivirira hydraulic system kukuvara uye kuratidza kukanganisa kwakasimba kwekutanga-yambiro kugona.
Nyaya yechipiri: Low-Quality Control Unit
Imwe Caterpillar 320D yaive neyakakuvadzwa OEM redunhu bhodhi yakatsiviwa neimwe yakaderera-mutengo imwe kubva kune isina mvumo. Kubva padanho rekutanga rekushandisa, iyo yekuchera yaiwanzoona injini idling isina mhinduro kubva kumabasa ekuchera, uye pasina mwenje yekunyevera inobatidzwa pane chiridzwa. Kuongororwa kwekuchengetedza kwakaratidza kuti loose soldering pamapini emukati eiyo yakaderera-quality control unit yakadzivirira iyo hydraulic system kubva pakugamuchira mirairo.
Kukanganisa uku kwakanonotsa basa kwemaawa akati kuti. Gare gare, nekuda kwekutadza kweiyo control unit kunyatsogadzirisa simba, kushandiswa kwemafuta kwakawedzera ne30%, uye zviito zvekuchera zvakava jerky. Iyo unit yakabviswa zvachose mushure memwedzi ye3 yekushandiswa nekuda kwekutsva kwedunhu.
SANY SY19E: Kuongororwa kweHunhu Zvakanakira zveIntegrated Control Units
Iyo yese-mu-imwe yakasanganiswa yekudzora unit yakashongedzerwa muSANY SY19E mini electric excavator muenzaniso wakajairwa weyepamusoro-mhando yekudzora unit. Iyi unit inosanganisa mabasa akawanda, anosanganisira yemagetsi drive MCU, yekuchaja OBC, uye yakaderera-voltage magetsi emagetsi DCDC. Kana ichienzaniswa neyechinyakare yakagovaniswa control unit, ine diki saizi uye yakasimba kuenderana.
Muchirongwa chekugadziridza mukati mufekitori yechikafu, iyo control unit yakashanda musynergy neSLSS hydraulic system kunyatso kudzora kuyerera kunoenderana nekuchinja kwemutoro. Yakaratidza yakanakisa micro-control yebhaketi, ichigonesa kuchera kona kwekona munzvimbo dzakamanikana. Zvichakadaro, zvakapetwa neine akangwara thermal manejimendi controller, iyo midziyo yakachengetedza tembiricha yakatsiga panguva yekushanda kweawa refu, isina maalarm emhosva akashumwa kunyange mushure memaawa masere akateedzana ebasa.
Kusiyana neizvi, midziyo inokwikwidza yetani imwechete yakashongedzerwa neyakajairwa mayuniti ekudzora anowanzoona kunonoka kwekuita. Uyezve, nekuda kwekushayikwa kwekupisa kwekupisa kwezvikamu zvavo zvekutonga, vakwikwidzi ava vakadzokorodza kukonzeresa kuvharwa kwekudzivirira nekuda kwekupisa. Kuenzanisa uku kunoratidza kunaka kwakanakira kweSANY's integrated control unit maererano nekugadzikana kwekuita uye nhanho yekubatanidza.
Volvo Excavators: Kuenzanisa kweKudzora Units 'Environment Adaptability
Muchirongwa chekuchera cheVolvo pachiteshi, zvikamu zviviri zvakaiswa neOEM control unit uye yechitatu-bato rekunyepedzera yekudzora unit, zvichiteerana, yekuenzanisa mashandiro munzvimbo dzekutakura zvinhu. Nzvimbo yechiteshi chengarava inoratidzirwa nehunyoro hwepamusoro uye kazhinji kacho kupfapfaidza munyu.
Iyo OEM control unit yakaratidza IP67 yekudzivirira chiyero ine yakavharwa dhizaini, imba inodzivirira-corrosion-yakagadziriswa, uye yekunyorova-inoputira pamaseketi emukati. Kwemakore maviri ekushandiswa, yakangosangana nekushanduka kwechiratidzo chidiki, icho chakaonekwa sechisina kunaka chekubatanidza waya-isina hukama neiyo control unit pachayo.
Kusiyana neizvi, mucherechedzi ane dhizaini yekunyepedzera akatanga kusangana nekukanganisa kwekutaurirana mushure memwedzi ye6 yekushandiswa, aine maalarm anoenderera pane chiridzwa. Kuongorora kweDisassembly kwakaratidza kuti imba yechikwata chemanyepo yaive isina kuvharwa zvakanaka; kupindira kwemunyu kupfapfaidza kwakakonzera kuora kwemapuranga emukati edunhu uye kuputsika kwepini-induced oxidation. Pamusoro pezvo, iyo yekunyepedzera inodzora unit haina kukwanisa kuenderana neiyo chiteshi chepamusoro-frequency vibration mamiriro. Munguva yekudengenyeka kunokonzerwa nekutakura zvinhu zvinorema, kuendesa data kwakavhiringidzwa kakawanda, zvichiita kuti zviitike zvisiri izvo zve hydraulic system. Pakupedzisira, chikwata chekunyepedzera chakatsiviwa neOEM nekuda kwekukuvara kusingagadzirike.
Doosan excavator yakangoerekana yavhara panguva yekushanda, paine chiridzwa chinoratidza "ECU yekutaurirana kukanganisa" uye "abnormal jenareta voltage." Iyo excavator yakatadza kutangazve mushure. Vashandi vekuchengetedza vakatevera maitiro ekugadzirisa matambudziko:
Yakasimbiswa kuti bhatiri voltage uye fuse zvaive zvakajairika.
Doosan Excavators: Kuziva Kudzora Chikamu Hunhu Kuburikidza Nekukanganisa Kuongororwa
Yakatarisa iyo ECU terminal ndokuona kuti voltage kubva kune emergency shutdown circuit kuenda kuECU yaive 0V (yakajairika voltage inofanira kunge iri 25V).
Yakazoonekwa tambo dzewaya dzakasakara sechikonzero chekutadza kwemagetsi eECU.
Panguva ino, mukana weiyo yepamusoro-yemhando yekudzora unit yakava pachena: mushure mekutadza kwemagetsi kwagadziriswa uye waya dzesimbi dzakabatanidzwazve, iyo OEM ECU yakabva yatangazve kushanda kwakajairika pasina kuvhiringika kwedata kana kukanganisa kwekuita. Yese paramita yakaramba yakagadzikana mumabasa aitevera.
Pakutanga, imwe yekuchera yeDoosan ine yakaderera-mhando ECU yakasangana newaya harness ipfupi-yedunhu kukanganisa. Mushure mekunge kukanganisa kwagadziriswa, iyo yakaderera-mhando ECU ichiri kugara ichisangana nemafuta jekiseni chiratidzo kusagadzikana. Yakazopedzisira yasimbiswa kuti iyo yakaderera-yemhando yemukati maseketi aive neasina kunaka ekurwisa kuvhundutsa, zvichikonzera kukuvadzwa kusingachinjike panguva pfupi yedunhu. Mhosva iyi inoratidza kuti yakaderera-mhando yekudzora zvikamu zvakaderera kune zvemhando yepamusoro maererano nekutadza kuramba.
Nyaya Itsva Holland Smart Power System-Yakafananidzwa Kudzora Chikamu: Yakabatanidzwa Dhizaini Inoratidza Yepamusoro-Unhu Kuita
Chidimbu chemidziyo yekuvaka chaive chakashongedzerwa neCase New Holland CSP smart power system, iyo inofananidzwa yekudzora unit inosanganiswa nedhijitari yemagetsi control pombi. Iyi control unit inotsigira mabasa akadai semagetsi anti-stall uye adaptive torque control. Munguva yekushanda kwakaoma, inogonesa kunyatsoenderana pakati peiyo hydraulic pombi yekunyudza simba uye injini iripo simba.
Semuyenzaniso, panguva inorema-basa rekuchera, iyo control unit inogona kugadzirisa hydraulic system parameters munguva chaiyo, ichibvumira midziyo kuti ishande yakadzikama pasi pehurongwa hwekumanikidzwa kwe315 bar pasina kukanganiswa kwemagetsi kana kusagadzikana kudzvinyirira nyaya. Zvichienzaniswa neyakajairwa midziyo ine pombi yakaparadzana uye dhizaini yeECU, iyi yakabatanidzwa yekudzora unit haingorerutsa dhizaini asiwo inoderedza kunonoka kutapurirana kwechiratidzo, kuvandudza kushanda zvakanaka ne20%.
Kusiyana neizvi, vacheri vemhando imwechete vakashongedzerwa neyakajairwa kudzora mayunitsi vanowanzoona injini yekumhanyisa madonhwe uye jerky hydraulic zviito pasi pemamiriro ekumanikidza. Uyezve, kushandisa kwavo mafuta kwaive ne18% yakakwira kupfuura iyo yemidziyo ine Case New Holland control unit. Izvi zvinoratidzira zvakakosha zvakakosha zveyepamusoro-mhando yekudzora mayuniti mune system synergy uye chaiyo mutemo
