Ina kore e taea e te Pūnaha Whakahaere Pūngao te whakarato i ngā māramatanga pono, ehara i te pūmanawa te raru i ngā wā katoa.
I roto i te maha o ngā kaupapa, ka tīmata te raruraru tūturu i te taumata mita.
Mena kāore e taea e te mita pūngao te whakarato i te whakawhitiwhiti kōrero pumau, te raraunga wā-tūturu tika, te tawhā hiko tika rānei, ka whakaaturia noa e te tūāpapa EMS ngā mōhiohio kāore i oti, i whakaroa rānei. Mō ngā whare arumoni, ngā whare ahumahi, ngā pūnaha PV rā, me ngā kaupapa rokiroki pūngao, me whiriwhiri te mea tikamita pūngao modbusnō reira he whakatau hangarau nui.
Ehara i te mea ko te mita pai anake te ine i te whakapaunga hiko. Me tautoko hoki i te tāutanga mahi, me whakawhitiwhiti kōrero pono ki ngā kaiwhakahaere hiko, ki ngā tūmau rānei, ā, me whakarato hoki i ngā raraunga e hiahiatia ana mō te tātari hiko, te aunoatanga, te pūrongo, me te arotau pūnaha.
He aha te hiranga tonu o Modbus i roto i ngā kaupapa EMS
Kei te whakamahia whānuitia tonutia a Modbus i roto i te whakahaere pūngao nā te mea he māmā, he tuwhera, ā, e tautokona ana e te maha o ngā tūāpapa EMS, BMS, PLC, me SCADA.
Mō ngā kaiwhakauru pūnaha, he mea nui tēnei nā te mea me kohikohi pinepine ngā raraunga pūngao mai i ngā taputapu rerekē puta noa i ngā rūma hiko, ngā wāhi whakaputa, ngā pūnaha pūngao rā, me ngā taputapu mīhini. Ka taea te whakauru i tētahi mita e tautoko ana i te Modbus ki roto i ngā hanganga o nāianei me te kore e akiaki i te kaupapa ki te whakawhirinaki ki tētahi tūāpapa kapua kati.
I te nuinga o ngā kaupapa EMS, e rua ngā kōwhiringa Modbus e whakaarohia whānuitia ana:
Modbus RTU i runga i te RS485e whakamahia ana mō ngā whakawhitiwhiti kōrero ā-ahumahi waea. He pai mō te whatunga ā-rohe pumau, te waea tawhiti, me te pōti e hangai ana ki te kaiwhakahaere.
Modbus TCPe whakamahia ana i runga i ngā whatunga IP. He māmā ake te hono atu ki ngā tūmau, ngā kuwaha, ngā papaaho whakahaere, me ngā tūāpapa hiko e hangai ana ki te whatunga ā-rohe.
Mō ngā kaupapa hou maha, ko te otinga pai ehara i te whiriwhiri i te kotahi anake. Mā te mita ngāwari e tautoko ana i te Modbus TCP me te Modbus RTU ka nui ake ngā kōwhiringa mā ngā kaiwhakauru pūnaha i te wā e whakatinanahia ana.
Tirohia te Pūnaha Hiko i te Tuatahi
I mua i te whakatairite i ngā āhuatanga o te pūmanawa, me whakaū te taiao hiko.
Tērā pea ka uru atu ki tētahi kaupapa EMS:
- Ngā pūnaha kotahi-wāhanga
- Ngā pūnaha wāhanga-wehewehe
- Ngā pūnaha waea-whā-wāhanga-toru
- Ngā pūnaha PV pūngao rā
- Ngā pūnaha rokiroki pūngao
- Ngā kawenga arumoni, arumoni rānei kua whakaranua
Mena ka tautokona e te mita te whirihoranga hiko kotahi anake, ka whakawhāitihia pea te whakatinanatanga ā muri ake nei. Mō ngā kaituku, ngā hoa OEM, me ngā kaiwhakauru pūnaha, mā te whakamahi i te tūāpapa mita kotahi puta noa i ngā momo kaupapa maha ka taea te whakaiti i te uaua o ngā rawa me te whakahaere i te whakamahere tāutanga.
Koia te take he nui ake te whai hua o te mita Modbus maha-pūnaha i te mita i hangaia mō te taiao waea pumau kotahi anake.
He mea nui te tāutanga o te rawhi CT mō ngā kaupapa whakahou
He uaua te whakaweto i te hiko, te hono anō rānei i ngā waea hiko i roto i te maha o ngā whare kua oti kē te whakatū.
Koinei te wāhi emita pūngao rawhi ctka whai hua.
Engari ko te tuku tika i te iahiko kawenga katoa mā roto i te mita, ka inehia e ngā mita rawhi CT te iahiko mā roto i ngā whakawhiti iahiko o waho. He tino whai hua tēnei huarahi mō ngā kaupapa aroturuki pūngao whakahou nā te mea ka taea te whakaiti i te whakararuraru tāutanga me te tautoko i ngā tono iahiko teitei ake.
Mō ngā whare arumoni, ngā wheketere, ngā kura, ngā hōtēra, me ngā kaupapa whakahounga pūngao rā, he maha ngā wā ka whai hua ake te inenga e hangai ana ki te hiko CT i te inenga e hono tika ana.
I te wā e whiriwhiri ana i tētahi mita rawhi CT, tirohia:
- Ngā whakatauranga o nāianei CT e tautokona ana
- Te maha o ngā whakaurunga CT
- Te whānuitanga tika
- Te roa o te taura
- Tikanga tāutanga
- Mēnā ka tautoko te mita i te aroturuki kawemai/kaweake
Hei tauira, ko te tikanga, e toru ngā tāurunga CT e hiahiatia ana mō tētahi kaupapa wāhanga-toru. Tērā pea ka hiahiatia hoki he aroturukitanga taha-rua mō ngā kaupapa rokiroki pūngao me te rā kia mārama ai ki te whakamahinga me te whakaputanga.
He aha i Whai Hua Tonu ai te RS485
Ahakoa he mea noa te Ethernet me te WiFi i ēnei rā, he mea nui tonu te RS485 i roto i ngā pūnaha whakahaere ahumahi me te pūngao.
He ponomita pūngao rs485he mea whai hua ina hiahia te kaupapa ki te whakawhitiwhiti kōrero waea, ki te pōti ā-rohe pumau, ki te whakauru rānei ki ngā kaiwhakahaere me ngā kuwaha ahumahi.
He tino pai te RS485 mō:
- Whakaurunga PLC
- Te pōti a te kaiwhakahaere ā-rohe
- Ngā papa aunoatanga ahumahi
- Whakawhitiwhiti kōrero hurihanga rā
- Whakawhitiwhiti waea tawhiti
- Ngā pae kāore e pai ake te whakawhitiwhiti kōrero ahokore
Mō ngā kaupapa EMS, kāore te RS485 i tawhito. Koinei te kōwhiringa tino pumau me te tino matapaetia.
Kaua e titiro ki te kWh anake
He whai hua ngā raraunga kWh taketake, engari he maha atu ngā raraunga e hiahiatia ana mō ngā tūāpapa EMS o ēnei rā.
Me whakarato e te mita pūngao Modbus kaha:
- Ngaohiko
- Ināianei
- Auautanga
- Tauwehenga mana
- Mana hohe
- Mana tauhohe
- Mana āhua
- Kawemai/kaweake raraunga pūngao
He tino whai hua te mana tauhohe me te mana kitea mō te tātaritanga pūngao arumoni me te ahumahi. Ka āwhina ēnei i ngā kaihangarau ki te mārama ki te nui o te hiko e whakamahia ana, me te whai huatanga hoki o te whakahaere i ngā kawenga hiko.
Mō ngā tono rokiroki hiko pūngao rā me te pūngao, he mea nui anō hoki te aroturuki i ngā taha e rua. Me mōhio te tūāpapa EMS, te tūāpapa inverter rānei mēnā kei te kawemaihia te hiko mai i te whatunga hiko, kei te kaweakehia rānei mai i te papaanga.
Whakaarohia te EMS, te BMS, te SCADA me te Whakaurunga Kapua Motuhake
Kaua te mita e whakamahia ana i ngā kaupapa EMS e aromatawaihia mā te taupānga pūkoro anake.
Mō ngā kaupapa B2B, he mea nui ake te ngāwari o te whakaurunga.
I runga anō i te kaupapa, me whakapā atu pea te mita ki:
- Ngā papaaho EMS
- Ngā papaaho BMS
- Ngā pūnaha SCADA
- Ngā kaiwhakahaere PLC
- Ngā kaitahuri pūngao rā
- Ngā kaiwhakahaere rokiroki pūngao
- Ngā tūmau kapua tūmataiti
- Ngā papaaho ā-rohe
Koia te take he mea nui ngā kawa whakawhitiwhiti kōrero pēnei i a Modbus RTU, Modbus TCP, MQTT, me HTTP. Mā ēnei ka taea e ngā kaiwhakauru pūnaha te whakatau mēnā me pānui ā-rohe ngā raraunga, me tuku ki tētahi tūmau tūmataiti, me hono rānei ki tētahi tūāpapa whakahaere pūngao nui ake.
Te Wāhi e Taunga ai a PC4713
Mō ngā kaupapa e hiahia ana ki te whakawhitiwhiti kōrero Modbus, te whatunga RS485, me te aroturuki e hangai ana ki te rawhi CT, ngā hua pēnei i teOWON PC4713-W-485kua hangaia mō ngā tono EMS, BMS, PV rā, me ngā tono aroturuki pūngao ahumahi.
Ka tautoko te PC4713-W-485 i te whakawhitiwhiti WiFi me te RS485. Ka tautokona e tana whakawhitiwhiti WiFi te HTTP, MQTT, me te Modbus TCP, ko te tauranga RS485 ia e tautokona ana te Modbus RTU. Ka tautokona hoki te aroturuki wā-tūturu o te ngaohiko, te iahiko, te tauwehenga mana, te auau, te mana hohe, te mana tauhohe, te mana kitea, me te rere pūngao e rua ngā taha.
Nā tēnei he mea pai mō ngā kaupapa me kohikohi raraunga pūngao e tētahi tūāpapa EMS, tūmau ā-rohe, kaiwhakahaere inverter, pūnaha aunoatanga ahumahi rānei.
Mō ngā kaiwhakauru pūnaha e rapu ana i tētahi pūnaha tauine-rahimita pūngao modbus, ka taea e tētahi tūāpapa CT me te tautoko RS485 me te Modbus TCP te whakaiti i te mōrearea whakauru me te whakapai ake i te ngāwari o te whakatinanatanga mō te wā roa.
Ngā Whakaaro Whakamutunga
Ko te whiriwhiri i tētahi mita pūngao Modbus mō te whakaurunga EMS ehara i te mea ko te kimi noa i tētahi taputapu e tautoko ana i a Modbus.
Ko te pātai pai ake ko:
Ka taea e te mita te whakarato raraunga tika, whakawhitiwhiti kōrero pono, tāutanga ngāwari, me ngā tawhā hiko e ranea ana mō te kaupapa?
Mō ngā whare arumoni, ngā pūnaha PV o te rā, ngā whare ahumahi, me ngā kaupapa rokiroki pūngao, ko te kōwhiringa pai rawa atu he mita e tautoko ana i te Modbus TCP, Modbus RTU, te whakawhitiwhiti kōrero RS485, te ine rawhi CT, me te aroturuki pūngao e rua ngā taha.
Mā tēnei huinga ka taea e ngā kaiwhakauru EMS te hanga i ngā pūnaha aroturuki pūngao pono, tauine, me te rite mō ngā mea kei te heke mai.
