1 Maonero eElevator Communication Systems

Elevator kutaurirana maseketi (OR) inova nechokwadi chekuchinjana kwedata pakati pezvinhu zvakakosha, zvichikanganisa kuchengetedzwa kwekushanda uye kushanda nesimba. Gwaro iri rinobataCAN bhaziuyeRS-yakatevedzana maprotocol, kupa ruzivo rwehunyanzvi rwekugadzirisa uye SEO-yakagadziridzwa kugadzirisa matambudziko.

1.1 CAN Bhazi System

Core Features

• Topology: Multi-node bhazi network inotsigira yakazara-duplex kutaurirana.

• Electrical Standards:

  • Differential Signaling: CAN_H (Yepamusoro) uye CAN_L (Yakaderera) tambo dzakamonyoroka dzekudzivirira ruzha.

  • Voltage Levels: Inotonga (CAN_H=3.5V, CAN_L=1.5V) vs. Recessive (CAN_H=2.5V, CAN_L=2.5V).

• Priority Mechanism:

  • Lower ID values ​​= Yepamusoro pekutanga (semuenzaniso, ID 0> ID 100).

  • Collision resolution kuburikidza otomatiki node kubvisa.

Applications

• Real-time kuchengetedza kutarisa

• Kurongeka kweboka rekutonga

• Fault code transmission

1.2 RS-Series Communication Protocols

Protocol Kuenzanisa

Mashandisirwo Akakosha

• RS-485: Horo yekufona masisitimu, mamiriro emota mhinduro.

• RS-232: Maintenance komputa interfaces.

Installation Guidelines

• Shandisatambo dzakamonyoroka dzine nhovo(AWG22 kana kukora).

• Kumisa bhazi rinopera ne120Ω resistors.

• Dzivisa nyeredzi topology; koshesadaisy-chain connections.

1.3 Elevator Communication Architecture

Mana Key Subsystems

1. Group Control: Inorongedza akawanda elevator kuburikidza neCAN bhazi.

2. Mota Systems: Inogadzirisa mirairo yemukati kuburikidza neRS-485.

3. Horo Zviteshi: Inobata kunze mafoni; zvinodahoro simba mabhokisi(H10-H20).

4. Ebetsero Mabasa: Kupinda kwemoto, kutarisa kure.

Power Management

1.4 Dambudziko rekugadzirisa

1. Basic Checks:

   • Kuyera bhazi voltage (CAN: 2.5-3.5V; RS-485: ± 1.5-5V).

   • Simbisa zvinopikisa zvekumisa (120Ω yeCAN/RS-485).

2. Signal Analysis:

   • Shandisa oscilloscope kuona waveform kukanganisa.

   • Monitor CAN bhazi mutoro (

3. Isolation Testing:

   • Bvisa nodes kuti uone zvikamu zvisina kunaka.

   • Tsiva zvinhu zvinofungidzirwa (semuenzaniso, mabhokisi emagetsi ehoro).

2 General Troubleshooting Matanho

Kukanganisa kwekutaurirana mumasisitimu ezvikwiriso kunogona kuratidza nenzira dzakasiyana, asi kutevedzera nzira yakarongeka kunogonesa kuongororwa uye kugadziriswa. Pazasi pane matanho akakwenenzverwa ekuona nekugadzirisa OR nyaya dzedunhu, dzakagadzirirwa SEO uye kujekesa kwehunyanzvi.

2.1 Ziva Yakashata Yekutaurirana Bhazi kuburikidza neP1 Bhodhi Error Codes

Zviito Zvikuru:

1. Tarisa P1 Board Codes:

   • Masisitimu echikuru: Makodhi egeneric (semuenzaniso, "E30" yekukanganisa kwekutaurirana).

   • Masisitimu emazuva ano: Makodhi akadzama (semuenzaniso, "CAN Bus Timeout" kana "RS-485 CRC Error").

2. Rongedza Signal Isolation:

   • Muenzaniso: "Group Control Link Failure" kodhi inoratidza CAN nyaya dzebhazi, ukuwo "Hall Call Timeout" inonongedza kuRS-485 kukanganisa.

2.2 Ongorora Simba & Data Lines

Macheki Akakosha:

1. Continuity Testing:

   • Shandisa multimeter kuti uone kutendeseka kwewaya. Kune tambo refu, gadzira loop ine waya yekusara yekuyera kwakaringana.

2. Insulation Resistance:

   • Pima nemegohmmeter (> 10MΩ yeRS-485; > 5MΩ yebhazi reCAN).

   • Zano: Yepamusoro-frequency masaini anotevedzera mapfupi maseketi kana insulation yadzikisira.

3. Twisted Pair Specifications:

   • Wona kuti twist pitch (standard: 15–20mm yeCAN; 10–15mm yeRS-485).

   • Dzivisa tambo dzisiri dzemhando - kunyangwe zvikamu zvipfupi zvinokanganisa kutendeseka kwechiratidzo.

2.3 Ongorora Node Matambudziko kuburikidza neStatus LEDs

Maitiro:

1. Tsvaga Dzakashata Node:

   • CAN node: Tarisa "ACT" (chiitiko) uye "ERR" maLED.

   • RS-485 nodes: Simbisa "TX/RX" blink rates (1Hz = zvakajairika).

2. Common LED Pateni:

   LED State	Dudziro
   ACT yakatsiga, ERR yakadzimwa	Node inoshanda
   ERR kubwaira	CRC kukanganisa kana kusawirirana kweID
   ACT/RX yabviswa	Simba kana chiratidzo kurasikirwa

2.4 Simbisa Node Settings & Kugumisa Resistors

Configuration Checks:

1. Node ID Kusimbiswa:

   • Ita shuwa kuti maID anoenderana nepasi mabasa (semuenzaniso, Node 1 = 1st floor).

   • Zvitupa zvisingaenderani zvinokonzeresa kurambwa kwepaketi kana kubonderana kwebhazi.

2. Termination Resistors:

   • Inodiwa panoperera bhazi (120Ω yeCAN/RS-485).

   • Muenzaniso: Kana iyo node iri kure kwazvo ikachinja, bvisa chinopikisa.

Nyaya Dzakajairika:

• Kusipo kugumiswa → Zviratidzo zvechiratidzo → Huori hwedata.

• Ukoshi husina kunaka hwekudzivirira → Kudonha kwemagetsi → Kutadza kutaurirana.

2.5 Zvimwe Zvinotarisirwa

1. Firmware Consistency:

   • Manodhi ese (kunyanya zviteshi zvehoro) anofanirwa kumhanyisa shanduro dzesoftware dzakafanana.

2. Hardware Kuenderana:

   • Tsiva mapuranga ane zvikanganiso neshanduro dzinoenderana (semuenzaniso, mabhodhi eR1.2 eR1.2 node).

3. Kupindira Kwesimba:

   • Edzai AC masosi (semuenzaniso, maseketi ekuvhenekesa) eEMI uchishandisa spectrum analyzer.

   • Isa maferrite cores patambo dzekukurukurirana pedyo nemidziyo ine simba guru.

Mazano Eunyanzvi Ekuchengetedza

1. Cable Testing:

   • Shandisa anguva-domain reflectometer (TDR)kutsvaga kukanganisa kwetambo mumitsetse yakareba seri.

2. Grounding Check:

   • Kuyera voltage pakati pekukurukurirana tambo nhoo uye pasi (

3. Firmware Updates:

   • Gara uchifananidza bhodhi firmware shanduro (semuenzaniso, P1 v3.2 ine gonhi rekutonga v3.2).
