3. Raws li tag nrho qhov ntev ntawm cov khoom siv kho qhov muag, lub phaj tiv thaiv uas muaj qhov dav tsis pub tsawg tshaj 50 hli ntawm ob sab ntawm cov khoom siv kho qhov muag yuav tsum tau them, thiab cov phaj tiv thaiv yuav tsum tau ua los ntawm cov pob zeb.
4. Qhov chaw tso khoom yog nyob rau hauv cov chaw uas nquag khawb xws li kev nkag mus hauv nroog, uas tuaj yeem nteg nrog lub ntsej muag kos npe siv rau ntawm lub rooj tiv thaiv.
5. Ntawm qhov chaw tso rau hauv lub nroog lossis hauv cheeb tsam qhib, ntawm txoj kab ncaj nraim ntawm li 100 hli raws txoj kab hluav taws xob kho qhov muag, ntawm qhov chaw tig los yog qhov sib koom ua ke, cov cim qhia pom tseeb lossis cov ceg txheem ntseeg yuav tsum tau txhim tsa.
6. Thaum muab tso rau hauv qhov chaw tsis khov, qhov kho qhov muag cable sheath mus rau lub hauv paus ntawm cov qauv hauv av yuav tsum tsis pub tsawg tshaj 0.3m, thiab qhov tob ntawm optical cable sheath rau hauv av yuav tsum tsis pub tsawg tshaj 0.7m;Thaum nws nyob rau ntawm txoj kev los yog hauv av cultivated, nws yuav tsum tau kom tob tob, thiab yuav tsum tsis txhob tsawg tshaj li 1 m.
7. Thaum muab tso rau hauv cov av khov, nws yuav tsum tau muab faus rau hauv qab ntawm cov av khov.Thaum nws tsis tuaj yeem faus tob, nws tuaj yeem muab faus rau hauv cov av qhuav qhuav txheej lossis cov av rov qab nrog cov av zoo, thiab lwm yam kev ntsuas los tiv thaiv kev puas tsuaj rau cov kab hluav taws xob kho qhov muag kuj tuaj yeem coj mus..
8. Thaum ncaj qha faus optical cable kab sib tshuam nrog txoj kev tsheb ciav hlau, txoj kev loj lossis txoj kev, cov kav dej tiv thaiv yuav tsum hnav, thiab kev tiv thaiv kev tiv thaiv yuav tsum dhau ntawm txoj kev taug kev, ob sab ntawm txoj kev pavement thiab sab ntawm cov kwj deg los ntawm ntau tshaj 0.5m.
9. Thaum cov kab hluav taws xob faus ncaj qha nkag mus rau hauv cov qauv, lub raj tiv thaiv yuav tsum tau teeb tsa ntawm lub qhov hla ntawm txoj kab nqes, thiab lub nozzle yuav tsum tau thaiv los ntawm dej.
10. Qhov kev ncua deb ntawm qhov sib koom ua ke ntawm qhov ncaj qha faus optical cable thiab cov kab hluav taws xob uas nyob ib sab yuav tsum tsis pub tsawg dua 0.25m;Cov haujlwm sib koom ua ke ntawm cov kab sib txuas kho qhov muag yuav tsum tau staggered ntawm ib leeg, thiab qhov kev ncua deb yuav tsum tsis pub tsawg tshaj 0.5m;qhov sib koom ua ke ntawm txoj kab nqes hav yuav tsum yog kab rov tav;rau cov circuits tseem ceeb Nws yog ib qho tsim nyog yuav tsum tau tawm ntawm txoj hauv kev kom nteg cov khoom siv kho qhov muag hauv cheeb tsam hauv cheeb tsam pib txij li 1000mm ntawm ob sab ntawm cov khoom siv kho qhov muag.
