Ubukhulu besakhiwo
Usayizi we-Transmitter
1. ifomethi ye-serial
I-data bits 8 bits
Misa kancane 1 noma 2
Hlola Idijithi Ayikho
Isilinganiso se-Baud 9600 Isikhawu sokuxhumana okungenani singu-1000ms
2. Ifomethi yokuxhumana
[1] Bhala ikheli ledivayisi
Thumela: 00 10 Ikheli CRC (5 bytes)
Izimbuyiselo: 00 10 CRC (4 bytes)
Qaphela: 1. Ingxenye yekheli lomyalo wekheli lokufunda nokubhala kufanele libe ngu-00.
2. Ikheli liyibhayithi elingu-1 futhi ububanzi bungu-0-255.
Isibonelo: Thumela 00 10 01 BD C0
Ibuyisela 00 10 00 7C
[2] Funda ikheli ledivayisi
Thumela: 00 20 CRC (4 bytes)

Ukubuyisela: Ikheli 03 02 XX XX XX XX YY YY
Qaphela
| Ikhodi | Incazelo yomsebenzi | Qaphela |
| Ikheli | Inombolo yesiteshi (ikheli) | |
| 03 | Fikhodi yokukhipha | |
| 02 | Funda iyunithi byte | |
| XX XX | Idatha (phezulu ngaphambili, iphansi ngemva) | Hex |
| XX XX | Ikhodi ye-CRCCheck |
Ukuze ubale ikhodi ye-CRC:
1. Irejista ye-16-bit esethiwe ngaphambilini ithi FFFF nge-hexadecimal (okungukuthi, zonke zingu-1).Shayela le rejista ngerejista ye-CRC.
2. XOR idatha yokuqala ye-8-bit enebhithi engezansi yerejista ye-CRC engu-16 futhi ifake umphumela kurejista ye-CRC.
3.Shifta okuqukethwe kwerejista kwesokudla ngebhithi eyodwa (ubheke kwencane), gcwalisa ibhithi ephezulu kakhulu ngo-0, bese uhlola ibhithi elincane kakhulu.
4. Uma ibhithi ebaluleke kakhulu ingu-0: phinda isinyathelo sesi-3 (shintsha futhi), uma okuncane okubalulekile kungu-1: irejista ye-CRC ifakwe ku-XORed nge-polynomial A001 (1010 0000 0000 0001).
5.Phinda izinyathelo 3 no-4 kuze kube izikhathi ezingu-8 kwesokudla, ukuze yonke idatha ye-8-bit icutshungulwe.
6. Phinda izinyathelo 2 kuya kwezi-5 ukuze uthole ukucubungula kwedatha okungu-8-bit.
7.Irejista ye-CRC ekugcineni itholakele ikhodi ye-CRC.
8. Uma umphumela we-CRC ufakwa ohlakeni lolwazi, amabhithi aphezulu naphansi ayashintshaniswa, bese kuthi kancane kuqala.
1. Isikhundla sokufakwa kwenzwa singakhethwa phansi, ishubhu elikhulu elenziwe mathupha, insika yensimbi flange noma ophahleni lwendlu ngokwezidingo zangempela.
2.Lungisa izikulufu ezintathu zokulinganisa ku-chassis ukuze wenze izinga lokukhomba ibhamuza lezinga (ibhamuza lihlala maphakathi nesiyingi), bese uqinisa kancane kancane izikulufi zokulungisa ezintathu ze-M8 × 80;uma ibhamuza leleveli lishintsha, udinga ukulungisa kabusha.
3. Hlanganisa futhi ulungise inzwa njengoba kukhonjisiwe emfanekisweni ongenhla.
4. Ngemva kokulungisa, vula ibhakede lemvula bese usika izibopho zekhebula enayiloni kufaneli, faka kancane kancane amanzi ahlanzekile kunzwa yemvula, bese ubheka inqubo yokuphenduka yebhakede ukuze uhlole ukuthi idatha iyatholwa yini ethuluzini lokutholwa.Ekugcineni, amanzi amaningi (60-70mm) ayajovwa.Uma idatha eboniswa ithuluzi lokutholwa ihambisana nenani lamanzi ajovwe, ithuluzi livamile, ngaphandle kwalokho kufanele lilungiswe futhi lilungiswe.
5. Gwema ukuqaqa inzwa ngesikhathi sokufakwa.
1. Sicela uhlole ukuthi iphakheji iphelele futhi uhlole ukuthi imodeli yomkhiqizo iyahambisana yini nokukhetha.
2. Ungaxhumi ulayini ovuliwe.Hlola kuphela izintambo futhi uqiniseke ukuthi amandla avuliwe.
3.Ubude bekhebula lenzwa buzothinta isignali yokuphumayo yomkhiqizo.Ungabeki ngokungafanele izingxenye noma izintambo ezidayisiwe lapho umkhiqizo uphuma efekthri.Uma kunesidingo soshintsho, sicela uxhumane nomkhiqizi.
4. Inzwa kufanele ihlolwe njalo ukuze kukhishwe uthuli, udaka, isihlabathi, amaqabunga nezinambuzane, ukuze ungavimbeli umzila wokugeleza kwamanzi we-tube engenhla (i-funnel).Isihlungi se-cylindrical singasuswa futhi sigezwe ngamanzi.
5.Kunokungcola odongeni lwangaphakathi lwebhakede lokulahla, elingagezwa ngamanzi noma ngotshwala noma ngesisombululo samanzi sokuhlanza.Kwenqatshelwe ngokuphelele ukusula ngeminwe noma ezinye izinto, ukuze ungatholi amafutha noma unganwayi udonga lwangaphakathi lwebhakede lokulahla.
6. Ngesikhathi seqhwa ebusika, ithuluzi kufanele limiswe futhi lingabuyiselwa ekamelweni.
7. Sicela ulondoloze isitifiketi sokuqinisekisa kanye nesitifiketi sokuvumelana, futhi usibuyisele kanye nomkhiqizo lapho ulungisa.
1. Imitha yokubonisa ayinakho inkomba.Umqoqi angase angakwazi ukuthola ulwazi ngendlela efanele ngenxa yezinkinga zezintambo.Sicela uhlole ukuthi izintambo zilungile futhi ziqinile.
2.Inani elibonisiwe lesibonisi ngokusobala alihambisani nesimo sangempela.Sicela uthulule ebhakedeni lamanzi futhi uphinde ugcwalise ibhakede ngenani elithile lamanzi (60-70mm), futhi uhlanze udonga lwangaphakathi lwebhakede.
3. Uma kungezona izizathu ezingenhla, sicela uxhumane nomkhiqizi.
