Lub davhlau tswj lub computer yog lub hauv paus tseem ceeb ntawm UAV navigation thiab tswj kev ya davhlau. Raws li tus neeg nyiam drone, koj puas paub nws cov qauv? Cov editor nram qab no yuav qhia rau koj.
1. Cov maub los ua haujlwm tseem ceeb. Muaj cov txheej txheem dhau los (MPU), microprocessors (MCU), thiab cov teeb liab digital processors (DSP). Nrog rau txoj kev loj hlob ntawm FPGA thev naus laus zis, ntau tus txheej txheem tseem ceeb tig FPGAs thiab cov txheej txheem rau hauv cov txheej txheem tseem ceeb.
2. Secondary fais fab mov. Qhov thib ob fais fab mov yog ib feem tseem ceeb ntawm lub davhlau tswj computer. Qhov thib ob fais fab mov ntawm lub davhlau tswj lub computer feem ntau yog 5V, ± 15V thiab lwm yam DC fais fab mov voltages, thaum lub sij hawm tseem ceeb lub hwj chim mov ntawm lub drone nws txawv heev nyob ntawm seb tus qauv. Lub hauv paus fais fab mov txawv heev raws li cov qauv sib txawv, thiab cov khoom siv hluav taws xob tseem ceeb yuav tsum tau hloov pauv. . Integrated switching power supply modules yog tam sim no nquag siv.
3. Analog input/output interface. Lub analog input interface Circuit Court ua cov teeb liab hloov, nce kev hloov pauv, thiab analog / digital (A / D) hloov pauv ntawm cov tswv yim analog los ntawm txhua lub sensor, thiab tom qab ntawd muab nws rau microprocessor rau kev ua haujlwm sib xws. Analog signals feem ntau yuav muab faib ua ob hom: DC analog signals thiab AC modulated signals. Lub analog tso zis interface Circuit Court yog siv los hloov digital tswj cov teeb liab rau hauv analog tswj cov teeb liab uas tuaj yeem lees paub los ntawm servo mechanism, suav nrog analog / digital hloov dua siab tshiab, amplitude conversion thiab tsav circuits.
4. Discrete interface. Lub discrete input circuit yog siv los hloov cov kev hloov pauv sab hauv thiab sab nraud ntawm lub davhlau tswj lub computer rau hauv lub teeb liab sib xws nrog qib ua haujlwm ntawm microprocessor.
5. Kev sib txuas lus interface. Nws yog siv los hloov cov ntaub ntawv tau txais serial rau hauv cov ntaub ntawv uas tuaj yeem nyeem los ntawm lub ntsiab processor lossis hloov cov ntaub ntawv xa los ntawm lub ntsiab processor rau hauv cov ntaub ntawv sib xws. Lub davhlau tswj lub computer thiab lub sensor tuaj yeem sib txuas lus ntawm txoj kev tsheb npav xws li RS232 / RS422 / RS485 lossis ARINC429. Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, lwm txoj kev sib txuas lus hauv tsheb npav xws li tsheb npav 1553B kuj tseem yuav siv rau UAV system.
6. Kev tswj hwm ntau dua. Hom redundancy ntawm UAV davhlau tswj computer feem ntau yog dual redundancy configuration. Lub redundancy kev them nyiaj yug Circuit Court yog siv los txhawb kev sib koom tes ntawm lub redundant airborne computer, xws li: cov ntaub ntawv sib pauv Circuit Court ntawm channel computers, lub synchronization qhia Circuit Court, lub channel tsis ua hauj lwm logic synthesis Circuit Court thiab lub failover circuit. Cov ntaub ntawv sib pauv hloov hluav taws xob ntawm cov khoos phis tawj channel yog cov ntaub ntawv xov xwm rau kev sib qhia cov ntaub ntawv ntawm ob lub channel davhlau tswj computers. Lub synchronization qhia Circuit Court yog ib qho kev txhawb nqa Circuit Court rau kev sib nrig sib synchronization ntawm cov khoos phis tawj rov qab uas ua haujlwm synchronously. Cov channel fault logic synthesis circuit integrates cov kev soj ntsuam cov txiaj ntsig ntawm software saib xyuas thiab kho vajtse saib xyuas circuits, thiab nws cov zis yog siv rau kev ua tsis tiav thiab kev ua txhaum.
7. Cua sov Circuit Court. Nws feem ntau yog siv rau hauv lub davhlau tswj cov khoos phis tawj uas nws qhov chaw ua haujlwm siab tshaj qhov ntsuas kub ntawm qib kev lag luam kom ua tau raws li qhov xav tau ntawm lub zog xav tau los ntawm cov cua sov Circuit Court thiab cov txheej txheem cua sov.
8. Kev txheeb xyuas interface. Lub davhlau tswj lub computer yuav tsum muaj qhov tsim nyog interfaces los pab txhawb kev sib txuas nrog cov khoom siv tshuaj xyuas thawj kab thiab cov khoom siv tshuaj xyuas thib ob.
9. Flight control computer case. Nws cuam tshuam ncaj qha rau lub khoos phis tawj' lub peev xwm los tiv thaiv ib puag ncig hnyav, nrog rau nws txoj kev ntseeg siab, kev ruaj ntseg, thiab kev pabcuam lub neej.
