Ang itim na screen ng panel ng instrumento ng forklift ng BYD ay nag-uulat ng isang error, at ang plano sa pagpapanatili ng mga bahagi ng controller(larawan1)

Kapag ang isang electric forklift ay may itim na screen sa panel ng instrumento upang mag-ulat ng isang error, sa karamihan ng mga kaso ito ay malapit na nauugnay sa abnormalidad ng mga accessory ng controller. Kinakailangang sundin ang isang sistematikong proseso ng pagpapanatili upang unti-unting mag-imbestiga at maiwasan ang bulag na operasyon.

Una, magsagawa ng mga pagsisiyasat sa mga pangunahing link ng supply ng kuryente. Idiskonekta muna ang pangunahing supply ng kuryente ng forklift upang matiyak ang kaligtasan ng mga operasyon ng pagpapanatili. Suriin ang linya ng supply ng kuryente sa pagitan ng panel ng instrumento at ng controller upang makita kung maluwag, na-oxidized o nahuhulog ang mga terminal. Kung may nakitang abnormalidad, kailangang muling higpitan o linisin ang mga terminal. Kasabay nito, suriin kung ang boltahe ng supply ng kuryente ay nakakatugon sa mga na-rate na pamantayan ng kagamitan. Kung ang boltahe ay masyadong nagbabago, kinakailangang suriin ang katatagan ng output ng power module upang maalis ang problema sa itim na screen na dulot ng abnormal na supply ng kuryente.

Pangalawa, tumuon sa pagtuklas ng mga pangunahing bahagi ng controller. Buksan ang shell ng controller, linisin ang panloob na alikabok at sari-sari, at suriin kung ang mga elektronikong bahagi tulad ng mga capacitor at resistor sa motherboard ay nakaumbok o naaagnas. Ang pinsala sa mga naturang bahagi ay maaaring magdulot ng pagkaantala sa paghahatid ng signal. Pagkatapos ay tuklasin ang input at output port ng controller, at gumamit ng multimeter upang sukatin ang halaga ng signal ng port upang matukoy kung ito ay nasa loob ng normal na hanay. Kung ang halaga ay abnormal, ang kasalanan ng kaukulang linya o bahagi ay kailangang suriin pa.

Pagkatapos, i-verify ang link ng paghahatid ng signal. Ang pakikipag-ugnayan ng data sa pagitan ng panel ng instrumento at ng controller ay naisasakatuparan sa pamamagitan ng linya ng signal. Kinakailangang suriin kung ang signal cable ay nasira o nasira sa loob dahil sa labis na baluktot. Maaaring gamitin ang isang signal detector upang subukan ang katayuan ng paghahatid ng signal. Kung ang signal ay naantala o seryosong pinahina, ang isang kwalipikadong signal cable ay dapat palitan at ang mga parameter ng signal ay dapat na muling i-calibrate upang matiyak ang maayos na paghahatid ng data.

Panghuli, kumpletuhin ang pagpapatakbo ng pag-verify pagkatapos ng pag-overhaul. Ibalik ang lahat ng koneksyon sa linya, i-on ang pangunahing power supply, at simulan ang forklift upang subukan ang status ng display ng panel ng instrumento. Kung ang panel ng instrumento ay bumalik sa normal at walang error prompt, kailangan itong patuloy na tumakbo sa loob ng isang yugto ng panahon upang obserbahan ang katatagan; kung ang kasalanan ay umiiral pa rin, ito ay kinakailangan upang muling ayusin ang proseso ng pagpapanatili upang suriin kung ang iba pang mga kaugnay na bahagi ay hindi normal.

Sa buong proseso ng pagpapanatili, kinakailangang bigyang-pansin ang anti-static na proteksyon upang maiwasan ang static na pinsala sa mga precision na elektronikong bahagi sa controller; sa parehong oras, gumana nang mahigpit alinsunod sa mga detalye ng manual ng pagpapatakbo ng kagamitan, at huwag i-disassemble ang mga bahagi nang walang malinaw na mga punto ng kasalanan sa kalooban upang maiwasan ang pangalawang pinsala.
