Makina opangira jekeseni wamagetsi opangira injini zazing'ono
Wotchedwa SPC5-L9177A-K02, mawonekedwe a ECU amapangidwira njinga zamoto, ma scooters, ndi ma tayala atatu - makamaka omwe ayenera kukwaniritsa Euro 5, Bharat Stage VI (BSVI), ndi miyezo ya China IV. ST imadziwikiranso ntchito pamajenereta, ma injini a nautical ndi zida zaulimi.
Imatha kuyendetsa ma jakisoni, cholumikizira, galimoto yopondera ndi tachometer, komanso mawonekedwe okhala ndi zomasinthasintha zomverera - njira zonse zimatetezedwa kuzungulira kufupi komanso kuzizira kwambiri. Kulumikizana kudutsa cholumikizira cha magalimoto 48.
Zofunikira kwambiri ndi ST's SPC572L 32bit Power Architecture MCU ndi L9177A - yomalizayi imapangidwa pa njira ya BCD ndipo imaphatikizapo zida zamagetsi ndi oyendetsa mainjiniya omwe amapanga injini zokhala ndi ma cylinders amodzi - 300mA 5V yowongolera yomwe ili ndi mafuta otsekedwa, 5V yotsatira kutsatira kutetezera batire lalifupi, ma driver awiri oyendetsera mafuta, driver wa injini osakonza mayendedwe oyenda, chowongolera makina a okosijeni, komanso mawonekedwe azidziwitso.
Onse awiri a SPC572L ndi L9177A "apangidwira makamaka kuti agwiritse ntchito komanso azisowa pamsika", anatero ST, yemwe STGD18N40 IGBT ndi L9616 CAN mawonekedwe IC nawonso ali pa bolodi.
Zopezekanso pa SPC572L MCU ndi nthawi, mayendedwe 16, njira 56 zochokera, 1.5Mbyte kuwerenga-ndikulemba (RWW) Flash (ndi EEPROM emulation), 64kbyte general-cholinga data SRAM, awiri desiles / serial peripheral interface (DSPI) module , chosinthira ma analogue-mpaka-digito ndikudziyesa nokha.
Thandizo limachokera ku SPC5Studio IDE (malo ophatikizidwa otukuka) omwe amaphatikiza oyendetsa magalimoto otsika, SPC572L timer module Confurator ndi malaibulale a injini crank position sensate ndi othandizira othandizira.
"Kuthetsa zovuta zomwe zimakhudzana ndi jakisoni wamagetsi amagetsi, pulogalamu yofunsira yoyambilira yopangidwa ndi eMoticom imathandizira ogwiritsa ntchito kuyamba ndikuwongolera injini yama injini," inatero ST. Izi zikuwoneka ngati gawo limodzi la ma cylinder 250cc 4 ndi jekeseni m'modzi, komanso kuphatikiza kutentha kwa mpweya, kutentha kwa madzi ndi kubwezeredwa kwa barometric.
SPC5-L9177A-K02, yomwe imayeza 100 x 70mm, itha kugulidwa kuchokera ku Arrow.
