Thuirt:Conaltradh, cuideachd a 'cleachdadh am facal conaltradh, tha cuid de dhaoine a' creidsinn gu bheil an litir a tha claon toraidhean, fhad 'sa tha an naidheachd a' fàbharachadh a 'phròiseas agus an t-slighe, ach chan eil coltas gu bheil cus eadar-dhealachadh ann an bun-bheachd seòrsachadh nach urrainn a dhol an sàs. Ge bith an e conaltradh no conaltradh a th ’ann, is e cleachdadh diofar chomharran, leithid dealan, magnetachd, solas, msaa, gus am fiosrachadh a chuir an cèill a chuir chun cheann-uidhe. As a simple example, if there are two students living in Building 1 and Building 2, they discuss that if they see a white shirt, they will skip class together today. Here can be simplified as, in a particular scenario, white shirt = skip class together, it corresponds to the communication protocol, in addition to several actions involved: 1. hanging white shirt 2. see white shirt 3. day light enough to see the shirt, respectively, corresponding to the communication theory of encoding, decoding, channel. Of course, the actual life of the communication, to be much more complex than the example of the white shirt, the need for reliability, stability, economy and other perspectives to consider the choice of channel, as well as the cost of encoding and decoding equipment and so on, for example, we can choose the 4G of the Internet of Things communication network, but the cost is high, you may give up some of the stability, to choose the GPRS Internet of Things communication network.
Thuirt: A bharrachd air na gnìomhan bunaiteach protocol, a chaidh a thoirt a-steach gu h-àrd, cùis chudromach ann an conaltradh ioT a dhèanamh àireamh airson a chuir an cèill gu soilleir cò a th 'ann, tron àireamh is urrainn dhaibh inneal sam bith san t-saoghal a chomharrachadh aig an tùs agus an ceann-uidhe, agus tron inneal iomchaidh, am fiosrachadh a dhèanamh a rèir slighe sònraichte a thèid a chuir eadar an dà rud. Canar "seòladh" ris an seo, a tha a 'tòiseachadh le mar a thèid seòladh a shònrachadh, agus a' leantainn le mar a leigeas an comharra an seòladh ceann-uidhe a lorg tro riaghailtean sònraichte.
said：The two most important address concepts in IoT communication are IP address and MAC address. IP address is the address used by the Internet protocol, while MAC address is the address used by the Ethernet protocol. tha seòladh 48-bit gun samhail aig gach nód de Ethernet, a tha air a riaghladh leis a’ bhuidheann IEEE, agus tha an seòladh MAC air a losgadh a-steach do gach cairt lìonra le neach-dèanamh a’ chairt. A network card manufacturer burns the MAC address into each card, the MAC address is as unique as the identity card number. tha an dàimh mapaidh eadar an seòladh MAC agus an seòladh IP an-còmhnaidh ga àrdachadh agus ag ùrachadh le gach aoigh, a thig gu bhith na “chlàr mapaidh seòlaidh”, agus tha an seòladh IP coltach ri àireamh dorais. So a device with a certain MAC1 ID card, can today in the door number IP1 to stay, can also tomorrow in the door number IP2 to stay, the same MAC2 ID card device can also be in the IP1 to stay.
Comparable to IP addresses are URL (Uniform Resoure Locator) addresses, meaning Uniform Resource Locator, referring to the address of Internet files on the Web, URLs use numbers and letters in a certain order to determine an address, URLs must be converted to door numbers (ie, seòlaidhean IP) le frithealaichean DNS gus faighinn a-mach càite a bheil am faidhle air a chuir air frithealaiche air an lìon.
II. Conaltradh Pile Carbaid
thuirt: 1. CAN communication between vehicle and DC pile based on GB/T 27930-2023
thuirt: Is e CAN an giorrachadh de Lìonra Sgìreil Rianadair, a tha air a leasachadh le BOSCH, companaidh Gearmailteach a tha ainmeil airson leasachadh agus cinneasachadh stuthan dealanach chàraichean, agus mu dheireadh thàinig e gu bhith na inbhe eadar-nàiseanta (ISO11898), agus is e aon de na raointean as fharsainge a chleachdar. busaichean air an t-saoghal. Ann an Ameireaga a Tuath agus taobh an iar na Roinn Eòrpa, tha protocol bus CAN air a thighinn gu bhith na bhus àbhaisteach airson siostaman smachd coimpiutair chàraichean agus LANan smachd gnìomhachais freumhaichte, agus tha protocol J1939 air a dhealbhadh airson làraidhean mòra agus carbadan innealan troma le CAN mar am pròtacal bunaiteach.
Thuirt: An-dràsta, faodaidh cleachdadh Sìona agus Iapan conaltradh a chur ri bacadh air cosgais luath. Anns a 'inbhe againn, thathas a' toirt iomradh air an ìre àbhaisteach againn, tha Sruth Coitcheann Ciorrachadh DC air a mhìneachadh: A 'cur crìoch air ceangal corporra - Cunnart Cusglaidh ìosal - Cìsean paramadair - Crìochnachaidh ro dheireadh.
said：After the low-voltage assisted power-up, the vehicle and the pile enter the communication phase until the end. Tron phròiseas conaltraidh, bidh an carbad agus an pile a 'gluasad fiosrachadh eadar a chèile, Canar "Teachdaireachd" ris, a tha a' tòiseachadh le PR an Tagging Pile, B a 'tòiseachadh leis a' charbad Pile VCU, BMS fiosrachadh, tro na mìneachaidhean sin, is urrainn fios a bhith againn gun tèid a 'phròiseas creiteach, an carbad dealain agus pile dealain a thaobh a bhith air an iomlaid eatorra.
