1.1Mwachidule

Chotsekera chimodzichi chingagwiritsidwe ntchito kwambiri pozindikira chilengedwe, kuphatikiza kusonkhanitsa phokoso, PM2.5 ndi PM10, kutentha ndi chinyezi, kuthamanga kwamlengalenga, ndi kuwala.Imayikidwa mu bokosi la louver, zidazo zimatengera njira yolumikizirana ya MODBUS-RTU, kutulutsa kwa siginecha ya RS485, ndipo mtunda wolumikizana kwambiri ukhoza kufika 2000 metres (kuyezedwa).Chotumizira ichi chimagwiritsidwa ntchito kwambiri pazochitika zosiyanasiyana zomwe zimafunika kuyeza kutentha kwa chilengedwe ndi chinyezi, phokoso, khalidwe la mpweya, kuthamanga kwa mumlengalenga ndi kuunikira, ndi zina zotero. Ndi zotetezeka komanso zodalirika, zokongola m'mawonekedwe, zosavuta kuziyika, komanso zolimba.

1.2Mawonekedwe

Mankhwalawa ndi ang'onoang'ono, olemera kwambiri, opangidwa ndi zipangizo zamakono zotsutsana ndi ultraviolet, moyo wautali wautumiki, kafukufuku wokhudzidwa kwambiri, chizindikiro chokhazikika, cholondola kwambiri.Zigawo zazikuluzikulu zimatenga zinthu zomwe zimatumizidwa kunja, zomwe zimakhala zokhazikika komanso zodalirika, ndipo zimakhala ndi miyeso yambiri yoyezera, mzere wabwino, ntchito yabwino yopanda madzi, kugwiritsa ntchito bwino, kuyika kosavuta, ndi mtunda wautali wotumizira.

◾ Kusonkhanitsa phokoso, kuyeza kolondola, kuchuluka kwake kumafikira 30dB~120dB.

◾ PM2.5 ndi PM10 amasonkhanitsidwa nthawi yomweyo, osiyanasiyana: 0-1000ug/m3, kusamvana 1ug/m3, wapadera wapawiri-pafupifupi deta kusonkhanitsa ndi basi calibration luso, kusasinthasintha akhoza kufika ± 10%.

◾ Kuyeza kutentha kwa chilengedwe ndi chinyezi, gawo loyezera limatumizidwa kuchokera ku Switzerland, muyeso ndi wolondola, ndipo mitunduyo ndi -40 ~ 120 madigiri.

◾ Mitundu yosiyanasiyana ya 0-120Kpa yamphamvu ya mpweya, yogwira ntchito mosiyanasiyana.

◾ Gawo lotolera zowunikira limagwiritsa ntchito kafukufuku wowoneka bwino kwambiri, ndipo kuchuluka kwa kuwala ndi 0 ~ 200,000 Lux.

◾ Gwiritsani ntchito dera lodzipatulira la 485, kulumikizana kokhazikika, 10 ~ 30V wide voltage range magetsi.

Kukhazikitsa ndi kugwiritsa ntchito mapulogalamu

3.1Kusankha mapulogalamu

Tsegulani phukusi la data, sankhani "Debugging software" --- "485 parameter configuration software", pezani "485 parameter configuration tool"

3.2Zokonda za parameter

①、Sankhani doko loyenera la COM (onani doko la COM mu "My Computer-Properties-Device Manager-Port").Chithunzi chotsatirachi chikulemba mayina a oyendetsa osiyanasiyana osiyanasiyana 485 converters.

②, Lumikizani chipangizo chimodzi chokha padera ndikuchilimbitsa, dinani kuyeserera kwa pulogalamuyo, pulogalamuyo idzayesa kuchuluka kwa baud ndi adilesi ya chipangizochi, kuchuluka kwa baud ndi 4800bit / s, ndipo adilesi yokhazikika ndi 0x01 .

③、Sinthani adilesi ndi kuchuluka kwa baud malinga ndi zosowa za ogwiritsa ntchito, ndipo nthawi yomweyo funsani momwe chipangizocho chilili panopa.

④, Ngati mayeso sanapambane, chonde yang'ananinso mawaya a zida ndi kukhazikitsa 485 driver.

4.2Tanthauzo la mtundu wa data

Adopt Modbus-RTU communication protocol, mawonekedwe ake ndi awa:

Kapangidwe koyambirira ≥4 mabayiti anthawi

Adilesi = 1 byte

Khodi ya ntchito = 1 byte

Dera la data = N mabayiti

Kuwona zolakwika = 16-bit CRC code

Nthawi yomaliza kupanga ≥ 4 mabayiti

Khodi ya adilesi: adilesi yoyambira ya transmitter, yomwe ili yapadera pa intaneti yolumikizirana (factory default 0x01).

Khodi yogwira ntchito: malangizo ogwiritsira ntchito operekedwa ndi wolandirayo, chotumizirachi chimangogwiritsa ntchito code 0x03 (werengani zolembetsa).

Dera la data: Dera la data ndizomwe zimalumikizirana, tcherani khutu kumtunda wapamwamba wa data ya 16bits poyamba!

Khodi ya CRC: cheke cheke ziwiri-byte.

Host query frame structure:

Adilesi kodi	Kodi ntchito	Lembani adilesi yoyambira	Kulembetsa kutalika	Chongani code low bit	Chiwerengero chachikulu cha cheke
1 bati	1 bati	2 bati	2 bati	1 bati	1 bati

Kapangidwe ka chimango cha akapolo:

4.4Kulumikizana kwa protocol chitsanzo ndi kufotokozera

4.4.1 Funsani za kutentha kwa zida ndi chinyezi

Mwachitsanzo, funsani za kutentha ndi chinyezi: adilesi ya chipangizocho ndi 03

Adilesi kodi	Kodi ntchito	Adilesi yoyamba	Kutalika kwa data	Chongani code low bit	Chiwerengero chachikulu cha cheke
0x03 pa	0x03 pa	0x01 0xF4	0x000x02 pa	0x85 pa	0x7 ndi

Response chimango (mwachitsanzo, kutentha ndi -10.1 ℃ ndi chinyezi ndi 65.8% RH)

Adilesi kodi	Kodi ntchito	Chiwerengero cha mabayiti ovomerezeka	Mtengo wa chinyezi	Mtengo wa kutentha	Chongani code low bit	Chiwerengero chachikulu cha cheke
0x03 pa	0x03 pa	0x04 pa	0x020x92	0xFF 0x9B	0x79 pa	0xfd pa

Kutentha: Kwezani mu mawonekedwe a nambala yothandizira pamene kutentha kuli kotsika kuposa 0 ℃

0xFF9B (Hexadecimal)= -101 => Kutentha = -10.1℃

Chinyezi:

0x0292(Hexadecimal)=658=> Chinyezi = 65.8%RH

Mavuto wamba ndi njira zothetsera

Chipangizocho sichingalumikizane ndi PLC kapena kompyuta

Chifukwa chotheka:

1) Kompyutayo ili ndi madoko angapo a COM ndipo doko losankhidwa ndilolakwika.

2) Adilesi ya chipangizocho ndi yolakwika, kapena pali zida zomwe zili ndi ma adilesi obwereza (zosasintha za fakitale ndizo 1)

3) Mtengo wa baud, cheke njira, pang'ono ya data, ndi kuyimitsa pang'ono ndizolakwika.

4) Nthawi yoponya voti ndi nthawi yodikirira kuyankha ndi yayifupi kwambiri, ndipo zonse ziyenera kukhazikitsidwa pamwamba pa 200ms.

5) Waya wokwana 485 wachotsedwa, kapena mawaya A ndi B amalumikizidwa mobwerera.

6) Ngati chiwerengero cha zida ndi chachikulu kwambiri kapena mawaya ndi otalika kwambiri, magetsi ayenera kukhala pafupi, onjezani chowonjezera cha 485, ndikuwonjezera kukana kwa 120Ω nthawi yomweyo.

7) Dalaivala ya USB kupita ku 485 sinayikidwe kapena kuonongeka.

8) Kuwonongeka kwa zida.

Zowonjezera: Kukula kwa chipolopolo
