8.1 Oghere Usoro nkwukọrịta interface
● EIA485serial interface, ọkara-duplex asynchronous nkwurịta okwu;
Ọnụego Baud: 19200;
● Ụdị agwa: 1 mmalite bit, 8 data ibe n'ibe, 1 nkwụsị bit, enweghị otu, zipu ma nata data site na mmalite dị ala.
8.2 Zipu ma nata usoro data
● Data format: niile data bụ hexadecimal format, ọ bụla na-eziga na na-anata data gụnyere: 2 iwu byte uru, 0~ multiple data bytes, 1 check code byte;
● 4 izipu na ịnata iwu na mkpokọta, dị ka egosiri na eserese 8.1

1 Ntọala mmalite nke ihuenyo ọkụ bụ usoro nnabata nzikọrịta ozi, akwadoro maka ịnata data. Oge ọ bụla na-enweta otu data, dị ka iwu nke ịnata data si dị, melite ọdịnaya data ma tọọ usoro nzikọrịta ozi ka izipu, na-aga n'ihu data ezigara. Mgbe ezipụ data ahụ, tọọ usoro nzikọrịta ozi ka ọ bụrụ ịnata ọzọ.

3 Ntọala mmalite nke sistemu ndị ahịa chọrọ ka ọ bụrụ ọnọdụ izipu ozi nzikọrịta ozi, oge ọ bụla ka ezipuchara data ahụ, tọọ usoro nzikọrịta ozi ka ọ nweta ozugbo, kwadebe maka ịnata data nke ihuenyo ọkụ zitere.
4 Mgbe ihuenyo ọkụ natara data ezitere site na sistemu ndị ahịa, ziga data ka usoro nyocha a gachara. Ya mere, n'ihi na ndị ahịa usoro, mgbe na-eziga data oge ọ bụla, na-emekarị, kwesịrị ịtụle 20 ~ 30ms na-eche na-enweta data.

● Nzipu oge: N'oge mmalite, setịpụ interface serial iji nweta, mgbe a na-enweta iwu sitere na usoro ndị ahịa, debe interface serial ka ịnyefe. Wee zipu data dabere na iwu enwetara, mgbe izipu data ahụ, a ga-emegharị serial interface iji nweta.
● Na-aga n'ihu na-eziga: mgbe iwu uru natara bụ 0x95, 0x9A, malite na-aga n'ihu na-eziga ìhè ihuenyo doo ozi.
● N'ọnọdụ nke izipu na-aga n'ihu, ọ bụrụ na edobere onye ọ bụla nke axis ngwa anya na ihuenyo ọkụ, zipu data serial n'okpuru ọnọdụ na okirikiri nyocha ọ bụla agwụla mgbe interface serial dị, ka ọ dị ugbu a, interface serial ga-adị. atọrọ ka ibunye.
● N'ọnọdụ nke izipu na-aga n'ihu, ma ọ bụrụ na ọ dịghị axis anya na ihuenyo ọkụ na-edebe ma ọ bụrụ na ọ dị na interface serial (mgbe ịnyefe data a), a ga-edozi ihe ntanetị ahụ iji nweta, na-echere ịnweta data.
● ịdọ aka ná ntị: na ọnọdụ nke na-aga n'ihu na-ezipụ, ndị ahịa usoro bụ mgbe niile n'akụkụ na-enweta data, mgbe na-ebufe dị mkpa, ọ nwere ike na-aga n'ihu n'okpuru ọnọdụ na ìhè ihuenyo adịghị edebe na ga-agwụ agwụ na 20 ~ 30ms mgbe. enwetara data, ma ọ bụghị ya, ọ nwere ike ịkpata nsogbu nkwurịta okwu n'usoro nke a na-apụghị ịkọ, ọ pụkwara ime ka mmebi nke interface interface, mgbe ọ ka njọ.
