Maupangiri Okwanira a Mitsubishi Elevator Communication Circuits (OR): Protocols, Architecture & Troubleshooting

1 Chidule cha Elevator Communication Systems

Mabwalo olumikizirana ma elevator (OR) amawonetsetsa kusinthana kwa data pakati pa zinthu zofunika kwambiri, kukhudza mwachindunji chitetezo ndi magwiridwe antchito. Bukuli likuphimbaCAN basindiRS-mndandanda wa ma protocol, kupereka zidziwitso zaukadaulo pakukonza ndi njira zothetsera mavuto za SEO.

1.1 CAN Bus System

Zofunika Kwambiri

• Topology: Multi-node bus network imathandizira kulumikizana kwathunthu.

• Miyezo Yamagetsi:

  • Zizindikiro Zosiyanasiyana: CAN_H (Zam'mwamba) ndi CAN_L (Zotsika) zingwe zopotoka zachitetezo chaphokoso.

  • Miyezo ya Voltage: Dominant (CAN_H=3.5V, CAN_L=1.5V) vs. Recessive (CAN_H=2.5V, CAN_L=2.5V).

• Njira Yofunika Kwambiri:

  • Ma ID apansi = Chofunika kwambiri (mwachitsanzo, ID 0> ID 100).

  • Kusintha kwa kugundana kudzera pakuchotsa ma node.

Mapulogalamu

• Kuwunika chitetezo nthawi yeniyeni

• Kugwirizana kwamagulu

• Kutumiza kwa code yolakwika

Kufotokozera kwa Wiring

1.2 RS-Series Communication Protocols

Kufananiza kwa Protocol

Ntchito Zofunika

• Mtengo wa RS-485: Makina oyitanitsa kuholo, ndemanga zamagalimoto.

• Mtengo wa RS-232: Kukonza zolumikizira makompyuta.

Malangizo Oyika

• Gwiritsani ntchitozingwe zopota zotchinga(AWG22 kapena kupitilira apo).

• Kuyimitsa basi kumatha ndi120Ω resistors.

• Pewani ma topology a nyenyezi; kuika patsogolokugwirizana kwa daisy-chain.

1.3 Kapangidwe ka Elevator Communication

Makiyi Othandizira Anayi

1. Kuwongolera Gulu: Imagwirizanitsa ma elevator angapo kudzera pa basi ya CAN.

2. Makina Agalimoto: Imayang'anira malamulo amkati kudzera pa RS-485.

3. Malo Odyera: Imagwira mafoni akunja; amafunaholo mphamvu mabokosi(H10-H20).

4. Ntchito Zothandizira: Kufikira ozimitsa moto, kuyang'anira kutali.

Kuwongolera Mphamvu

1.4 Njira Yothetsera Mavuto

1. Macheke Oyambira:

   • Yezerani magetsi a basi (CAN: 2.5-3.5V; RS-485: ± 1.5-5V).

   • Tsimikizirani zoletsa zothetsa (120Ω za CAN/RS-485).

2. Kusanthula Zizindikiro:

   • Gwiritsani ntchito oscilloscope kuti muwone kupotoza kwa mawonekedwe.

   • Yang'anirani mabasi a CAN (

3. Kuyesa Kudzipatula:

   • Lumikizani mfundo kuti muzindikire zigawo zolakwika.

   • Bwezerani zinthu zomwe zikuganiziridwa (mwachitsanzo, mabokosi amagetsi a holo).

2 Njira Zothetsera Mavuto Onse

Kulephera kwa kulumikizana m'makina okwera kumatha kuwonekera m'njira zosiyanasiyana, koma kutsatira njira yokhazikika kumapangitsa kuti munthu azindikire bwino komanso kuthetsa vutoli. Pansipa pali masitepe okhathamiritsa ozindikiritsa ndi kuthetsa nkhani za OR OR, zopangidwira SEO komanso kumveka bwino kwaukadaulo.

2.1 Dziwani Mabasi Olakwika Olankhulana kudzera pa P1 Board Error Codes

Zochita Zofunika:

1. Onani P1 Board Codes:

   • Machitidwe akale: Ma code a Generic (mwachitsanzo, "E30" pazolakwika zolumikizirana).

   • Makina Amakono: Ma code atsatanetsatane (mwachitsanzo, "CAN Bus Timeout" kapena "RS-485 CRC Error").

2. Ikani patsogolo Kudzipatula kwa Signal:

   • Chitsanzo: Khodi ya "Group Control Link Failure" ikuwonetsa zovuta za mabasi a CAN, pomwe "Hall Call Timeout" imalozera ku zolakwika za RS-485.

2.2 Yang'anani Mphamvu & Mizere Yama data

Macheke Ovuta:

1. Kupitiliza Kuyesa:

   • Gwiritsani ntchito multimeter kuti mutsimikizire kukhulupirika kwa waya. Pazingwe zazitali, pangani lupu lokhala ndi mawaya opuma kuti muyezedwe molondola.

2. Kukana kwa Insulation:

   • Yezerani ndi megohmmeter (> 10MΩ pa RS-485; > 5MΩ pa basi ya CAN).

   • Langizo: Ma siginecha apamwamba kwambiri amatsanzira mafupi afupikitsa ngati kutchinjiriza kwawonongeka.

3. Zopindika Pawiri:

   • Tsimikizirani kupindika (muyezo: 15–20mm kwa CAN; 10–15mm kwa RS-485).

   • Pewani zingwe zosagwirizana - ngakhale zigawo zazifupi zimasokoneza kukhulupirika kwa ma sigino.

2.3 Dziwani Zovuta za Node kudzera pa Status LEDs

Ndondomeko:

1. Pezani Ma Node Olakwika:

   • Ma node a CAN: Chongani "ACT" (ntchito) ndi "ERR" ma LED.

   • Node za RS-485: Tsimikizirani kuchuluka kwa "TX/RX" (1Hz = zachilendo).

2. Mitundu Yodziwika ya LED:

   LED State	Kutanthauzira
   ACT mokhazikika, ERR yazimitsidwa	Node ntchito
   ERR kuphethira	Vuto la CRC kapena kusamvana kwa ID
   ACT/RX kuchotsedwa	Kutaya mphamvu kapena chizindikiro

2.4 Tsimikizirani Zosintha za Node & Termination Resistors

Macheke a kasinthidwe:

1. Kutsimikizika kwa Node ID:

   • Onetsetsani kuti ma ID akugwirizana ndi ntchito zapansi (mwachitsanzo, Node 1 = 1st floor).

   • Ma ID osagwirizana amayambitsa kukana kwa paketi kapena kugundana kwa mabasi.

2. Termination Resistors:

   • Zofunikira pomaliza mabasi (120Ω pa CAN/RS-485).

   • Chitsanzo: Mbali yakutali ikasintha, sunthani chopingacho.

Mavuto Ambiri:

• Kuyimitsa kukusowa → Kuwonetsa kwa ma Signal → Kuwonongeka kwa data.

• Mtengo wotsutsa wolakwika → Kutsika kwamagetsi → Kulephera kwa kulumikizana.

2.5 Mfundo Zowonjezera

1. Kusasinthika kwa Firmware:

   • Ma node onse (makamaka maholo) akuyenera kugwiritsa ntchito mapulogalamu ofanana.

2. Kugwirizana kwa Hardware:

   • Sinthani matabwa olakwika ndi mitundu yofananira (monga ma board a R1.2 a R1.2 node).

3. Kusokoneza Mphamvu:

   • Yesani magwero a AC (mwachitsanzo, mabwalo ounikira) a EMI pogwiritsa ntchito spectrum analyzer.

   • Ikani ma ferrite cores pazingwe zoyankhulirana pafupi ndi zida zamphamvu kwambiri.

3 Zolakwika Zolumikizana Pamodzi

3.1 Cholakwika: Mabatani Apansi Pagalimoto Osayankha

Zomwe Zingatheke & Njira Zothetsera:

3.2 Zolakwa: Mabatani Oyimba Ku Hall Sakuyankha

Zomwe Zingatheke & Njira Zothetsera:

3.3 Zolakwa: Kuletsa Mokha Kwa Mafoni Olembetsedwa Panthawi Yogwira Ntchito

Zomwe Zingatheke & Njira Zothetsera:

Malangizo Aukadaulo Pakukonza

1. Kuyesa kwa Chingwe:

   • Gwiritsani ntchito atime-domain reflectometer (TDR)kupeza zolakwika za chingwe pamizere yayitali.

2. Grounding Check:

   • Yezerani voteji pakati pa zishango za chingwe cholumikizirana ndi nthaka (

3. Zosintha za Firmware:

   • Nthawi zonse fananizani mitundu ya firmware ya board (mwachitsanzo, P1 v3.2 yokhala ndi chitseko cha v3.2).
