GENERAL DESCRIPTION

Chizvarwa chechipiri cheKuvaka Otomatiki Kadhi chinounza kuRaspberry Pi chikuva zvese zvinopinda uye zvinobuda zvinodiwa paKuvaka otomatiki Systems. Yakatsiga kusvika kumazinga masere, kadhi rinoshanda neshanduro dzese dzeRaspberry Pi, kubva kuZero kuenda ku8.
Maviri eRaspberry Pi's GPIO pini anoshandiswa kuI2C kutaurirana. Imwe pini yakagoverwa kune anovhiringidza anobata, achisiya 23 GPIO mapini aripo kumushandisi.
Zvisere zvinopinda zvepasirese, zvinosarudzika, rega iwe uverenge masaini 0-10V, kuverenga kuvharwa, kana kuyera tembiricha uchishandisa 1K kana 10K thermistors. Zvina 0-10V zvinogoneka zvinobuda zvinogona kudzora mwenje dimmers kana zvimwe zvigadzirwa zvemaindasitiri. Zvina 24VAC triac zvinobuda zvinogona kudzora AC relay kana kudziyisa uye kutonhora michina. Zviratidzo zve LED zvinoratidza mamiriro ezvose zvinobuda. Iyo RS485/MODBUS chiteshi inobvumidza inenge isina muganho yekuwedzera. Chekupedzisira asi chisiri chidiki, nyowani 1-WIRE chiteshi inogona kushandiswa kuverenga tembiricha kubva kuDS18B20 sensor.
TVS diode pane zvese zvinopinda zvinodzivirira kadhi rekunze ESD. Fuse iri pabhobho resettable inoidzivirira kubva kune kabudura netsaona. Imwe 24V AC kana DC simba sosi inogona kupa 5V/3A yeRaspberry Pi.

   Iyo purogiramu ichapindura nerondedzero yemirairo iripo.

BOARD RAYOUT

Mana General Chinangwa LEDs anogona kudzorwa musoftware. Iwo ma LED anogona kuvhurwa kuti aratidze mamiriro echero kupinza, kubuda kana kwekunze maitiro.

Stack LEVEL JUMPERS

Nzvimbo nhatu dzekuruboshwe dzejoni J3 dzinoshandiswa kusarudza stack level yekadhi:

INPUT SELECTION JUMPERS

Iwo masere epasirese ekuisa anogona kuve ega ega jumper akasarudzwa kuti averenge 0-10V, 1K kana 10K thermistors kana kubata kuvharwa / chiitiko counters. Iyo yakanyanya kuwanda kwemakaunda ezviitiko ndeye 100 Hz.

RS-485/MODBUS COMMUNICATION

Iyo Yekuvaka Automation Kadhi ine yakajairwa RS485 transceiver iyo inogona kuwanikwa zvese neiyo yemuno processor uye neRaspberry Pi. Iyo inodiwa gadziriso yakaiswa kubva kune matatu bypass jumpers pane yekumisikidza yekubatanidza J3.

Kana majumper akaiswa, Raspberry Pi inogona kutaurirana nechero mudziyo une RS485 interface. Mukugadzirisa uku, Kuvaka Otomatiki Kadhi ibhiriji rinongoshanda iro rinongoshandisa mazinga ehardware anodiwa neRS485 protocol. Kuti ushandise iyi gadziriso, unofanirwa kuudza processor yemuno kuti isunungure kutonga kwebhazi reRS485:
~$ megabas [0] wcfgmb 0 0 0 0
Kana majumper akabviswa, kadhi rinoshanda seMODBUS muranda uye rinoshandisa iyo MODBUS RTU protocol. Chero MODBUS tenzi anogona kuwana zvese zvinongedzo zvekadhi, uye kuseta zvese zvinobuda uchishandisa yakajairwa MODBUS mirairo. Rondedzero yakadzama yemirairo inoshandiswa inogona kuwanikwa paGitHub:
https://github.com/SequentMicrosystems/megabas-rpi/blob/master/Modbus.md
Mumagadzirirwo ese ari maviri processor yenzvimbo inoda kurongedzerwa kuburitsa (jumpers yakaiswa) kana kutonga (jumpers yakabviswa) masaini eRS485. Ona mutsara wekuraira online rubatsiro kune rumwe ruzivo.

SIMBA ZVINODIWA

Iyo Yekuvaka Automation Kadhi inoda yekunze 24VDC/AC yakadzorwa magetsi. Simba rinopihwa kubhodhi kuburikidza neyakazvitsaurira yekubatanidza mukona yekumusoro yekurudyi (ona BOARD LAYOUT). Iwo mabhodhi anogamuchira ingave DC kana AC magetsi sosi. Kana magetsi eDC akashandiswa, polarity haina kukosha. Yemunharaunda 5V regulator inopa anosvika 3A simba kuRaspberry Pi, uye 3.3V regulator inopa simba maseketi edhijitari. Isolated DC-DC converters anoshandiswa kusimbisa relay.

TINOKURUMBIRA KUSHANDISA CHETE 24VDC/AC POWER SUPPLY
KUTI SIMBA RASPBERRY PI CARD
Kana akawanda Kuvaka otomatiki Makadhi akaturikidzana pamusoro peumwe neumwe, isu tinokurudzira kushandisa imwechete 24VDC/AC magetsi ekupa simba makadhi ese. Mushandisi anofanira kupatsanura tambo uye kumhanya waya kune yega yega kadhi.
KUSHANDISA SIMBA:
• 50 mA @ +24V

UNIVERSAL INPUTS

Iyo Yekuvaka Automation Kadhi ine masere epasirese ekuisa ayo anogona kusvetuka akasarudzwa kuyera 010V masiginecha, 1K kana 10K thermistors kana kubata kuvharwa / chiitiko counters kusvika ku100Hz.

HARDWARE WATCHDOG

Iyo Yekuvaka Automation Kadhi ine yakavakirwa-mukati hardware watchdog iyo inovimbisa kuti yako mishoni-yakakosha purojekiti icharamba ichimhanya kunyangwe Raspberry Pi software yakarembera. Mushure mesimba kumusoro iyo watchdog inovharwa, uye inoshanda mushure mekunge yagamuchira yekutanga kuseta.
The default timeout ndeye 120 seconds. Kana yangoitwa, kana ikasagashira kusetwazve kubva kuRaspberry Pi mukati memaminitsi maviri, imbwa inorindira inocheka simba uye kuridzosera mushure memasekondi gumi.
Raspberry Pi inoda kuburitsa reset rairo paI2C chiteshi nguva isati yapera pane watchdog.
Iyo nguva yenguva mushure mesimba kumusoro uye inoshanda nguva yenguva inogona kusetwa kubva kumutsara wekuraira. Nhamba yezvigadziriso inochengetwa muflash uye inogona kuwanikwa kana kucheneswa kubva pamutsetse wekuraira. Yese iyo watchdog mirairo inotsanangurwa neiyo online rubatsiro basa.

ANALOGI ZVINOPIWA/ZVINOBUDZWA CALIBRATION

Ese mapinisheni eanalogi uye zvakabuda zvakanamirwa pafekitori, asi mirairo yefirmware inobvumira mushandisi kudzokorodza bhodhi, kana kuigadzirisa kuti iite zvirinani. Zvese zvinopinda uye zvinobuda zvakayerwa mumapoinzi maviri; sarudza mapoinzi maviri ari padyo nekubvira kumagumo maviri echiyero. Kuti uenzanise zvinopinda, mushandisi anofanira kupa masaini eanalog. (Eksample: kuyera 0-10V yekupinda, mushandisi anofanira kupa 10V inogadziriswa magetsi emagetsi). Kuti uenzanise zvinobuda, mushandisi anofanira kuburitsa murairo wekuseta chinobuda kune yaunoda kukosha, kuyera mhedzisiro uye kuburitsa iyo calibration command kuchengetedza kukosha.
Iwo ma values ​​anochengetwa muflash uye curve yekupinda inofungidzirwa kuve mutsara. Kana kukanganisa kukaitwa panguva yekuenzanisa nekunyora murairo usiriwo, murairo weRESET unogona kushandiswa kugadzirisa zviteshi zvose muboka rinoenderana kune fekitari tsika. Mushure meRESET calibration inogona kutangwazve.
Bhodhi rinogona kuverengerwa pasina kunobva masaini eanalogi, nekugadzirisa kutanga zvabuda uyezve kuendesa zvakagadziriswa zvinobuda kune zvinoenderana. Iyo inotevera mirairo iripo yekuenzanisa:
