Tsawg- cov kab hluav taws xob tswj hluav taws xob xa mus rau cov kab hluav taws xob uas muaj qhov ntsuas qis qis, feem ntau yog siv los xa cov ntaub ntawv hais kom ua- xws li cov lus qhia tswj, ntsuas cov ntaub ntawv, thiab cov teeb liab - nruab nrab ntawm cov khoom siv hluav taws xob lossis cov tshuab. Lawv lub luag haujlwm tseem ceeb tsis yog hais txog qhov siab - lub zog hluav taws xob hluav taws xob, tab sis yog los ua "cov kab lus txib" thiab "cov kab hluav taws xob xaim hluav taws xob."
Xav txog cov kab ntau lawm uas siv tau los yog lub zog faib hluav taws xob ntawm ib lub tsev loj -. Kev pib thiab nres ntawm lub tshuab hluav taws xob, kev qhib thiab kaw ntawm cov li qub, cov ntaub ntawv tawm tswv yim los ntawm cov sensors, thiab lub teeb pom kev zoo thiab tua hluav taws xob teeb pom kev zoo -tag nrho cov kev ua no vam khom rau qhov raug thiab ua yuam kev- cov teeb liab tswj dawb. Tsawg- cov kab hluav taws xob tswj hluav taws xob ua haujlwm raws li cov kav dej uas nqa cov teeb liab no. Lawv xa cov lus txib ua haujlwm los ntawm lub chaw tswj hwm (xws li PLC lossis relay txee) rau kev faib ua haujlwm, thaum tib lub sijhawm relaying ntawm - qhov chaw teeb liab rov qab mus rau lub chaw tswj hwm, yog li tsim lub voj voog tswj kom tiav. Yog tsis muaj lawv, txawm tias cov cuab yeej siv tshuab siab tshaj plaws yuav ua rau tuag tes tuag taw thiab tsis tuaj yeem ua haujlwm hauv kev sib koom tes.
Piv rau cov fais fab cables tseem ceeb- uas feem ntau yog siv los xa hluav taws xob hluav taws xob- qis- cov kab hluav taws xob tswj hluav taws xob feem ntau ua haujlwm ntawm qhov hluav taws xob qis thiab nqa qis qis; Txawm li cas los xij, lawv raug rau cov kev cai tshwj xeeb hais txog cov teeb liab kev ruaj ntseg, tiv thaiv kev cuam tshuam, nrog rau kev yoog raws thiab ua haujlwm nyob rau hauv lawv qhov chaw tshwj xeeb.
