Umhlahlandlela ophelele weMitsubishi Elevator Communication Circuits (NOMA): Imithethonqubo, Izakhiwo kanye nokuxazulula izinkinga

1 Uhlolojikelele Lwezinhlelo Zokuxhumana Zekheshi

Amasekhethi okuxhumana kwe-Elevator (OR) aqinisekisa ukushintshana kwedatha okuthembekile phakathi kwezingxenye ezibalulekile, okuthinta ngokuqondile ukuphepha nokusebenza kahle. Lo mhlahlandlela uhlanganisaCAN ibhasifuthiAmaphrothokholi ochungechunge lwe-RS, ehlinzeka ngemininingwane yobuchwepheshe yokulungiswa kanye namasu okuxazulula izinkinga e-SEO-optimized.

1.1 CAN Uhlelo Lwebhasi

Izici ezibalulekile

• I-Topology: Inethiwekhi yebhasi ye-Multi-node esekela ukuxhumana okuphelele kwe-duplex.

• Amazinga Kagesi:

  • Umehluko Wokusayina: Izintambo ezisontekile ze-CAN_H (Phezulu) kanye ne-CAN_L (Phansi) zokuvikeleka komsindo.

  • Amazinga kagesi: Okunamandla (CAN_H=3.5V, CAN_L=1.5V) vs. Okuphindaphindiwe (CAN_H=2.5V, CAN_L=2.5V).

• I-Priority Mechanism:

  • Amanani e-ID aphansi = Okubaluleke kakhulu (isb, i-ID 0 > ID 100).

  • Ukulungiswa kokushayisana ngokuhoxiswa kwenodi okuzenzakalelayo.

Izinhlelo zokusebenza

• Ukuqapha ukuphepha kwesikhathi sangempela

• Ukuxhumanisa ukulawulwa kweqembu

• Ukudluliswa kwekhodi yephutha

1.2 I-RS-Series Communication Protocols

Ukuqhathaniswa Kwephrothokholi

Ukusetshenziswa Okubalulekile

• RS-485: Amasistimu okushaya ucingo ehholo, impendulo yesimo semoto.

• RS-232: Ukulungisa ukuxhumana kwekhompyutha.

Imihlahlandlela yokufaka

• Sebenzisaizintambo ezivikelwe ezisontekile(AWG22 noma ugqinsi).

• Ukuqeda ibhasi iphetha nge120Ω resistors.

• Gwema ama-topology enkanyezi; beka phambiliizixhumanisi ze-daisy-chain.

1.3 I-Elevator Communication Architecture

Amasistimu angaphansi angukhiye amane

1. Ukulawula Kweqembu: Ixhumanisa amakheshi amaningi ngebhasi le-CAN.

2. Amasistimu Ezimoto: Iphatha imiyalo yangaphakathi nge-RS-485.

3. Iziteshi Zehholo: Iphatha izingcingo zangaphandle; idingaamabhokisi amandla ehholo(H10-H20).

4. Imisebenzi Esizayo: Ukufinyelela komlilo, ukuqapha okukude.

1.4 Umhlahlandlela wokuxazulula izinkinga

1. Amasheke Ayisisekelo:

   • Kala i-voltage yebhasi (CAN: 2.5-3.5V; RS-485: ± 1.5-5V).

   • Qinisekisa izimelambi zokunqamula (120Ω ye-CAN/RS-485).

2. Ukuhlaziywa Kwezimpawu:

   • Sebenzisa i-oscilloscope ukuze uthole ukuhlanekezela kwe-waveform.

   • Gada ibhasi le-CAN (

3. Ukuhlola Ukuhlukaniswa:

   • Nqamula ama-node ukuze uhlonze amasegimenti anephutha.

   • Shintshanisa izingxenye ezisolekayo (isb., amabhokisi kagesi ehholo).

2 Izinyathelo Ezijwayelekile Zokuxazulula Inkinga

Amaphutha okuxhumana ezinhlelweni zamakheshi angabonakala ngezindlela ezihlukahlukene, kodwa ukulandela indlela ehlelekile kuqinisekisa ukuhlonzwa okuphumelelayo nokuxazululwa. Ngezansi kunezinyathelo ezithuthukisiwe zokuhlonza nokuxazulula izinkinga zesekethe NOMA, ezenzelwe i-SEO nokucaca kobuchwepheshe.

2.1 Khomba Ibhasi Lokuxhumana Elinephutha Nge-P1 Board Error Codes

Izenzo Ezimqoka:

1. Hlola P1 Board Amakhodi:

   • Amasistimu amadala: Amakhodi ajwayelekile (isb, "E30" amaphutha okuxhumana).

   • Amasistimu wesimanje: Amakhodi anemininingwane (isb, "CAN Bus Timeout" noma "RS-485 CRC Error").

2. Beka Eqhulwini Ukuhlukaniswa Kwesiginali:

   • Isibonelo: Ikhodi "Yokuhluleka Kwesixhumanisi Sokulawula" ikhombisa izinkinga zebhasi ze-CAN, kanti "Isikhathi Sokuvala Sezingcingo" sikhomba kumaphutha e-RS-485.

2.2 Hlola Imigqa Yamandla Nedatha

Amasheke Abalulekile:

1. Ukuhlola Ukuqhubeka:

   • Sebenzisa i-multimeter ukuze uqinisekise ubuqotho bezintambo. Ngezintambo ezinde, dala iluphu enezintambo eziyisipele ukuze ukale ngokunembile.

2. I-Insulation Resistance:

   • Linganisa nge-megohmmeter (>10MΩ ye-RS-485; >5MΩ yebhasi le-CAN).

   • Ithiphu: Amasiginali wefrikhwensi ephezulu alingisa amasekhethi amafushane uma ukufakwa kwe-insulation kwehla.

3. Izichasiselo ezimbili ezisontekile:

   • Qinisekisa ukuphakama kwe-twist (okujwayelekile: 15–20mm kwe-CAN; 10–15mm kwe-RS-485).

   • Gwema izintambo ezingajwayelekile—ngisho namasegimenti amafushane aphazamisa ubuqotho besignali.

2.3 Thola Izinkinga Ze-Node ngama-LED Wesimo

Inqubo:

1. Thola Ama-Nodes Angalungile:

   • Amanodi e-CAN: Hlola "ACT" (umsebenzi) kanye nama-LED "ERR".

   • Amanodi e-RS-485: Qinisekisa amanani okucwayiza okuthi "TX/RX" (1Hz = evamile).

2. Amaphethini we-LED ajwayelekile:

   I-LED State	Ukuhunyushwa
   ACT iqinile, i-ERR ivaliwe	Ukusebenza kwe-node
   ERR ukucwayiza	Iphutha le-CRC noma ukungqubuzana kwe-ID
   ACT/RX ivaliwe	Ukulahlekelwa amandla noma isignali

2.4 Qinisekisa Izilungiselelo Ze-Node Nezinqamuleli Zokunqamula

Ukuhlola Ukucushwa:

1. Ukuqinisekiswa kwe-Node ID:

   • Qinisekisa ukuthi omazisi bafana nezabelo zesitezi (isb, iNode 1 = 1st floor).

   • Ama-ID angafani adala ukwenqatshwa kwephakethe noma ukushayisana kwebhasi.

2. Ukuqeda Resistors:

   • Kudingeka ezindaweni zokugcina zebhasi (120Ω ku-CAN/RS-485).

   • Isibonelo: Uma indawo ekude kakhulu ishintsha, hambisa isiphikisa.

Izinkinga Ezivamile:

• Ukunqanyulwa okungekho → Ukuboniswa kwesignali → Ukonakala kwedatha.

• Inani le-resistor elingalungile → Ukwehla kwamandla kagesi → Ukwehluleka kokuxhumana.

2.5 Okunye Okucatshangwayo

1. I-Firmware Ukungaguquguquki:

   • Wonke ama-node (ikakhulukazi iziteshi zehholo) kufanele asebenzise izinguqulo zesofthiwe ezifanayo.

2. Ukuhambisana kwe-Hardware:

   • Shintsha amabhodi anamaphutha ngezinguqulo ezifanayo (isb., amabhodi angu-R1.2 ngamanodi angu-R1.2).

3. Ukuphazanyiswa kwamandla:

   • Hlola imithombo ye-AC (isb, amasekhethi okukhanyisa) ye-EMI usebenzisa i-spectrum analyzer.

   • Faka ama-ferrite cores kumakhebuli okuxhumana eduze kwamadivayisi anamandla amakhulu.

Amathiphu Ezobuchwepheshe Okunakekela

1. Ukuhlola Ikhebula:

   • Sebenzisa ai-time-domain reflectometer (TDR)ukuthola amaphutha ekhebula emigqeni emide ye-serial.

2. Grounding Check:

   • Linganisa i-voltage phakathi kwezihlangu zekhebula lokuxhumana nomhlabathi (

3. I-Firmware Updates:

   • Hlala uqondanisa izinguqulo ze-firmware yebhodi (isb, i-P1 v3.2 enokulawula umnyango v3.2).
