16 LoRaWAN use cases on The IoT Market!

Má tá tú ag obair le gairis líonraithe, you may have heard of LoRaWAN use cases at one time or another. Is prótacal líonra fadraoin é. Cumasaíonn sé líonrú rudaí leis an Idirlíon fiú thar raonta níos faide le tomhaltas íseal fuinnimh. Réitíonn sé seo ceann de na fadhbanna móra atá roimh iarratais ar Idirlíon Rudaí go dtí seo. Le saolré ceallraí suas le cúig bliana agus costais chothabhála íseal don líonra braiteoirí, is féidir an LoRaWAN a úsáid le haghaidh réimse leathan feidhmchlár nua.

This gives you a brief overview of what the LoRaWAN solutions can do. San alt seo, féachaimid ar an ailtireacht, príomhghnéithe na croítheicneolaíochta, and the latest LoRaWAN use cases where it is used.

Cad é Teicneolaíocht LoRaWAN?

Is é an rud iontach faoin teicneolaíocht seo ná go bhfuil sí bunaithe ar chaighdeán oscailte. Úsáideann sé speictream neamhcheadúnaithe mar chuid den bhanda minicíochta ISM (“Tionscail, Eolaíoch, agus Leighis”, Gearmáinis: Tionscal, Eolaíocht agus Leigheas). San Eoraip, úsáideann an LoRaWAN an 868 Raon minicíochta MHz, agus i SAM an 915 Scaoiltear banda minicíochta MHz. Trí úsáid a bhaint as an speictream neamhcheadúnaithe, tá sé an-éasca do líonra féin a chur ar bun agus a úsáid. Many telecommunications operators are already benefiting from LoRaWAN use cases or offering the technology as part of their service offering in numerous countries worldwide. Comcast, KPN, Oráiste, Tá SK Telecom agus go leor soláthraithe eile ag cur seoltaí mórscála i bhfeidhm go gníomhach ina margaí. Déanann sé seo LoRaWAN níos suimiúla mar theicneolaíocht toisc go bhfuil sí comhoiriúnach le líonraí oibreoirí éagsúla – mór agus beag.

Déanann Comhghuaillíocht LoRa monatóireacht ar chaighdeán LoRaWAN, atá comhdhéanta ar a seal 500 baill a thacaíonn leis an bprótacal agus a ailíníonn go leor dá gcomhpháirteanna, táirgí, agus seirbhísí le LoRaWAN. Ina measc seo tá cuideachtaí mar MOKOSMART, ARM, Cisco, Micreascóp, agus ST.

What distinguishes LoRa from LoRaWAN?

Tosaímid leis an sainmhíniú ar LoRa – cad é go díreach agus conas atá sé difriúil ó LoRaWAN? Teicneolaíocht gan sreang í LoRa atá cosúil le teicneolaíochtaí níos coitianta mar Wi-Fi nó WLAN, Bluetooth, LTE, agus Zigbee. ach, is minic nach gclúdaíonn an teicneolaíocht na riachtanais go léir, rud a chiallaíonn go gcaithfidh úsáideoirí glacadh le comhréitigh. Freastalaíonn LoRa ar an éileamh ar chostas íseal, gairis a oibrítear le ceallraí ar féidir leo sonraí a tharchur thar raonta fada. ach, Ní hé LoRa an réiteach ceart chun sonraí a tharchur thar bandaleithid mhóra. Teicneolaíocht í LoRa a athraíonn sonraí le tarchur i dtonnta leictreamaighnéadacha. Tugtar an speictream scaipthe chirped ar an teicníc seo freisin， tá sé in úsáid i gcumarsáid mhíleata agus spáis ar feadh na mblianta. Tá sé mar gheall ar an raon fada cumarsáide agus an claonadh íseal chun cur isteach.

LoRaWAN, ar an lámh eile, Is é an prótacal MAC don líonra nóid LoRa ardfheidhmíochta atá bunaithe ar Idirlíon Rudaí, a chlúdaíonn raonta fada agus a bhfuil riachtanais ísle fuinnimh acu. It uses the advantages of LoRa described above and optimizes battery life and service quality for the LoRa nodes. Tá an prótacal go hiomlán déthaobhach, a chinntíonn tarchur teachtaireachta iontaofa (deimhniú). Cuirtear criptiú ó dheireadh go deireadh ar fáil chun críocha slándála agus cosanta sonraí, clárú fonótaí agus feidhmeanna multicast thar an aer. Cinntíonn an caighdeán comhoiriúnacht le líonraí LoRaWAN ar fud an domhain freisin.

LoRaWAN architecture

Den chuid is mó tá ceithre ghné in ailtireacht LoRaWAN:

• Nótaí deiridh

• Geata (bunstáisiúin / ródaire)

• Freastalaí Líonra

• Freastalaí feidhmchláir

Nótaí deiridh

Is feistí crua-earraí fisiciúla iad nóid deiridh atá feistithe le feidhmeanna braiteora, méid áirithe cumhachta ríomhaireachta agus modúl raidió chun na sonraí a aistriú go comhartha raidió. Is féidir leis na gairis deiridh seo sonraí a tharchur chuig an ngeata agus iad a fháil freisin. Fiú le ceallraí beag, féadfaidh siad maireachtáil roinnt blianta má chuirtear i mód codlata domhain iad chun an tomhaltas fuinnimh a bharrfheabhsú.

Nuair a sheolann gléas teachtaireacht chuig an ngeata, tugtar “uplink”. Tugtar an freagra a fhaigheann an teirminéal ón ngeata “downlink”. Ar an mbonn seo, déantar idirdhealú idir trí chineál feiste deiridh:

• Aicme A.

• Aicme B.

• Aicme C.

Tá an tomhaltas fuinnimh is ísle ag feistí Aicme A i gcomparáid leis an dá aicme eile. ach, ní fhéadfaidh siad seo nascnasc a fháil ach má tá nasc nasctha seolta acu. Tá feistí Aicme A oiriúnach chun sonraí a tharchur ag eatraimh bunaithe ar am (e.g.. gach 15 nóiméad) nó le haghaidh feistí a sheolann sonraí bunaithe ar imeachtaí (e.g.. má ardaíonn an teocht os a chionn 21 céimeanna nó titeann thíos 19 céimeanna).

Ligeann nóid deiridh Aicme B níos mó sliotán teachtaireachta do naisc anuas ná aicme A.. Laghdaíonn sé seo latency teachtaireachta ach níl sé chomh tíosach ar fhuinneamh freisin.

Faoi dheireadh, tá fuinneog ghlactha leanúnach ag aicme C nach bhfuil dúnta ach nuair a sheolann an gléas teachtaireacht nasctha. Dá bhrí sin, is é seo an leagan is lú atá tíosach ar fhuinneamh, a éilíonn foinse reatha leanúnach go minic chun oibriú.

Geataí

Tugtar modems nó pointí rochtana ar gheataí freisin. Is gléas crua-earraí é geata freisin a fhaigheann gach teachtaireacht LoRaWAN ó ghléasanna deiridh. Ansin déantar na teachtaireachtaí seo a thiontú ina sraith giotán is féidir a tharchur thar ghnáthghréasáin IP. Tá an geata nasctha leis an bhfreastalaí líonra a tharchuireann gach teachtaireacht.

Tá geataí trédhearcach agus níl ach cumhacht ríomhaireachta teoranta acu. Déantar tascanna níos casta sa fhreastalaí líonra. Ag brath ar úsáid agus cineál, tá geataí ar fáil i dhá leagan:

Geataí le húsáid faoi dhíon, e.g.. MKGW2-LW, MOKOSMART.

Freastalaí Líonra

Cuirtear gach teachtaireacht ó na geataí ar aghaidh chuig an bhfreastalaí líonra. Seo an áit a dtarlaíonn na próisis phróiseála sonraí níos casta. Tá an freastalaí líonra freagrach as:

1. Teachtaireachtaí a chur ar aghaidh / a chur ar aghaidh chuig an bhfeidhmchlár ceart;

2. Roghnú an gheata is fearr le haghaidh teachtaireachtaí downlink. De ghnáth déantar an cinneadh seo ar bhonn táscaire cáilíochta nasc, a ríomhtar ar a seal tríd an RSSI (Léiriú Neart Comhartha Faighte) agus an SNR (Comhartha le Cóimheas Torainn) de phaicéid a fuarthas roimhe seo;

3. Deireadh a chur le teachtaireachtaí dúblacha nuair a fhaigheann il-gheataí iad;

4. Teachtaireachtaí a chuirtear ó nóid deiridh agus teachtaireachtaí criptithe a chuirtear ar ais chuig na nóid a dhíchriptiú;

5. De ghnáth nascann geataí leis an bhfreastalaí líonra ar Phrótacal Idirlín criptithe (IP) nasc. De ghnáth cuimsíonn an líonra coimisiúnú an gheata agus comhéadan monatóireachta a chuireann ar chumas an tsoláthraí geataí a bhainistiú, lochtanna a leigheas, monatóireacht aláraim, srl. …

Freastalaí feidhmchláir

Is é an freastalaí feidhmchláir an áit a bhfuil an feidhmchlár IoT suite – tá sé seo úsáideach go háirithe maidir le sonraí a ghabhtar ag úsáid feistí deiridh. I bhformhór na gcásanna, Ritheann freastalaithe feidhmchláir trí scamall príobháideach nó poiblí, atá ceangailte le freastalaí líonra LoRaWAN agus a dhéileálann le próiseáil a bhaineann go sonrach le feidhmchlár. Tá an comhéadan leis an bhfreastalaí feidhmchláir á rialú ag an bhfreastalaí líonra.

LoRaWAN functions

• Bi-directional communication

Is féidir le teirminéal sonraí a tharchur chuig an ngeata agus iad a fháil de réir na socruithe. Is féidir na socruithe seo a ghlaoch laistigh den fheidhmchlár freisin.

• Logánú

An interesting function of LoRaWAN is localization without the need for GPS. Tá sé seo úsáideach go háirithe do chórais agus braiteoirí a rianú ós rud é go bhfuil sé éifeachtach ó thaobh ceallraí agus gur féidir é a chothabháil níos saoire ná na gnáthmhodhanna.

• Scalability

Dearadh LoRaWAN le haghaidh imscaradh mór IoT ina bhfuil na mílte feiste líonraithe le líon soláimhsithe geataí. Is féidir leis na geataí seo monatóireacht a dhéanamh ar ilbhealaí agus teachtaireachtaí iomadúla a phróiseáil ag an am céanna.

Maoin thábhachtach eile de chuid LoRaWAN is ea an luas ar féidir sonraí a tharchur. Tá rátaí difriúla sonraí ann is féidir a úsáid don tarchur. Tugtar fachtóirí scaipthe orthu seo freisin (SF). Cumasaíonn tarchur níos moille raon níos faide agus níos iontaofa.

Mar shampla, samhlaigh go bhfuil tú ag caint le duine atá an-ghar duit. Is féidir leat labhairt go han-tapa sa chás seo agus tuigeann do mhacasamhail gach a deir tú. Nuair a labhraíonn tú le duine atá i bhfad uait, caithfidh tú labhairt i bhfad níos moille le go dtuigfear tú. Baineann an prionsabal seo le prótacal LoRaWAN freisin.

• Ráta Sonraí Oiriúnaitheach

Le LoRaWAN, is féidir leis an líonra an luas a tharchuireann an gléas a sonraí a uasmhéadú go huathoibríoch. Tugtar an ráta sonraí oiriúnaitheach ar an bhfeidhm seo (nó ADR) and is particularly important to increasing the capacity of a LoRaWAN network. Ligeann ADR dúinn an líonra a scála go héasca trí gheata eile a chur leis. Mar gheall ar an ngeata seo, déanann a lán feistí deiridh a bhfachtóir scaipthe a choigeartú go huathoibríoch. Mar thoradh, tá na gairis aonair níos giorra “ar an aer”, rud a chiallaíonn níos mó acmhainne don líonra.

An ráta oiriúnaitheach sonraí (giorrúchán: ADR) is meicníocht shimplí í a athraíonn an ráta sonraí de réir na rialacha seo a leanas:

Má tá an neart comhartha raidió (ar a dtugtar freisin “nasc buiséid”) ard, is féidir an ráta sonraí a mhéadú;

Má tá an buiséad nasc íseal, is féidir an ráta sonraí a laghdú.

• Sábháilteacht

Tá sé tábhachtach do gach LPWAN réiteach slándála cuimsitheach a úsáid. Úsáideann LoRaWAN dhá leibhéal slándála: ceann don líonra agus ceann don fheidhmchlár. Cinntíonn slándáil an líonra barántúlacht na feiste deiridh sa líonra, cé go gcinntíonn leibhéal an fheidhmchláir nach bhfuil rochtain ag an oibreoir líonra ar shonraí feidhmchláir úsáideoirí deiridh. Úsáidtear criptiú AES le haghaidh malartú eochair.

Tá leibhéal an líonra freagrach as an nód a aithint. Seiceálann sé an dtagann teachtaireacht i ndáiríre ó ghléas ar leith agus meastar gur seiceáil sláine í freisin. Féadann sé orduithe MAC a chriptiú freisin.

Úsáidtear an leibhéal iarratais chun ualaí pá a dhíchriptiú agus a chriptiú.

Tá an dá eochracha criptithe le 128 giotán AES i mód BCE.

Scenarios for LoRaWAN use cases

Fuair ​​LoRaWAN a áit ar an margadh i dtéarmaí iarratas agus réimsí feidhme. Buíochas lena airíonna uathúla, Is fearr a oireann LoRaWAN do chásanna mar seo:

1. Rochtain ar leictreachas (leictreachas) teoranta nó srianta;

2. Tá sé deacair rochtain a fháil ar na láithreacha nó tá siad an-iargúlta;

3. Tá líon na bhfeistí deiridh i bhfad níos airde i gcomparáid le gnáth-naisc fón póca;

4. Ní gá do na feistí deiridh teachtaireachtaí a sheoladh go leanúnach.

How many LoRaWAN use cases are there

1. Rianú sócmhainní

   Many industries need to track the location and condition of valuable equipment to improve planning and operations. LoRaWAN sensors measure asset speed, load, temperature and humidity, post, vibration and other data and combine real-time and historical data to recommend maintenance before problems occur. With access to asset performance data, you can optimize your production schedule while also being notified when an asset is stolen or exceeds its intended scope.

2. Backflow preventer monitoring

   All industrial water customers require backflow preventers at water service inlets, which prevent contamination by allowing water to flow in one direction rather than the other. Being able to sense the presence of backflow with a LoRaWAN-based line monitor and immediately send an SMS or email alert to facility managers is important for the health and safety of workers and manufacturing systems.

3. Monatóireacht ar shlabhra fuar

   LoRaWAN is ideal for cold chain applications in the fresh food sectors and healthcare. Using LoRaWAN cold chain solution, you can track the temperature and humidity status of a product and report the temperature and humidity status to the system if the product status is abnormal, preventing the product from losing features or even breaking down.

4. Soil temperature and humidity monitoring

   For agriculture and landscaping, proper irrigation is the key to improving crops. Soils in different regions require different amounts of water, and the LoRaWAN Temperature and Humidity detector can be used to make more informed decisions based on the measured soil temperature and humidity, increasing production and reducing water waste.

5. Leak detection

   When the Earth’s resources, such as water, gas or chemicals, are in short supply, the key to solving this dilemma is to avoid resource leakage as much as possible. The water inside and outside industrial facilities will be monitored by the LoRaWAN Water Leak Detection and water immersion sensors. The system will alert the facility manager to take quick response and resolution when a failure occurs or an anomaly is detected.

6. Logistics and transportation

   LoRaWAN technology enables supply chain and logistics organizations to track assets that need to be transported over long distances in real-time. Vehicles and cargo can be easily monitored in real time over large geographic areas and harsh environments due to the technology’s long distance and low power consumption characteristics, as well as GPS-free geolocation. A fleet tracking system connected with LoRaWAN network can keep fleets in the field longer, thereby reducing costs, improving safety, providing visibility into maintenance issues, and improving operational efficiency across the board.

7. Parking lot monitoring

   It’s proved that finding available parking spaces enhances carbon emissions and traffic congestion. By deploying LoRaWAN sensors in parking spaces, accurate vehicle counts and detection at parking lot entrances and exits can be provided. Municipal and commercial revenue streams will be increased by capturing real-time parking data improves overall parking space utilization.

8. Pest management

   It’s necessary to protect facilities and people from contamination, damage, and rodents. ach, manual inspection is time-consuming and consumes amounts of material resources and manpower. LoRaWAN’s connected pest management solution improves visibility and allows real-time monitoring from anywhere. Uiscedhíonach, rugged traps provide a safe option for rodenticides. Simple mobile app and web pairing, real-time alerts when service is needed, improve efficiency and reduce costs for outdoor and indoor rodent control programs.

9. Monatóireacht chomhshaoil

   Many coastal cities experience prolonged flooding during moderate to high tides tend to leave thoroughfares and nearby roads in impassable water. These issues can be resolved by monitoring air quality, precipitation and other environmental factors. Weatherproof solar power units mounted on top of bridges and light poles remotely measure water levels on land or above bodies of water using LoRaWAN technology and ultrasonic sensors. These real-time environmental monitoring systems measure extra-local weather levels and air quality to predict flooding and inform citizens of hazardous conditions.

10. Public safety

    Integrated security and safety solutions are required by nearly all industries. IoT public safety solutions provide emergency responders with innovative technologies that help reduce risk and improve personal safety. LoRaWAN technology is being integrated into personal wearables such as ID tags and equipped with an emergency button to send instant SOS and the user’s location information. These solutions, deployed on enterprise and university campuses, are designed to address the 1-second attack interval and 7-second 911 call interval for cellphone-based solutions.

11. Space utilization

    Employees are increasingly mobile and rapidly shifting to an “anytime, áit ar bith” work philosophy. Mar thoradh, office space can be idle or overbooked, depending on unpredictable employee and visitor flows. Making the most of space has become a logistical challenge for businesses. Occupancy data obtained from LoRaWAN sensors eliminates guesswork and provides teams with actionable intelligence to enhance workplace practices, and increase employee productivity.

12. Steam trap monitoring

    Steam is widely used in various industries. Steam heating processes in factories drive turbines in power plants. A steam trap filters non-condensed gases and condensed steam without letting the steam escape. Steam traps fail on average 10 chun 30 percent per year, resulting in wasteful and costly inefficiency. Steam trap testing is a labor-intensive process that is usually done manually once a year. The LoRaWAN Trap monitoring system allows companies to frequently query their trap count to detect faults. The data is securely transmitted to the online building management system, providing dashboard reports showing whether there are traps that need to be repaired.

13. Tank monitoring

    A reliable system to monitor fuel levels is essential. Fuel delivery companies are key partners in smart industrial supply chain operations where fuel depletion can be detrimental. Without the means to measure fuel levels remotely, truck deliveries are often inefficient, driving up operating costs and complicating the delivery of customer service. Tank level and other valuable data can be sent over the network to the tank monitoring solution used by the supply company. Thairis sin, industrial operations can accurately predict fuel usage. Ar an mbealach seo, truck rolls and their carbon footprint can be reduced.

14. Temperature monitoring

    Maintaining the right temperature for valuable assets is important for healthcare, food service, and other industries. Temperature shifts can lead to catastrophic product loss. In addition to the damage to resources, these incidents can also cause brand, reputation, public image and other losses to companies. With low-power sensors, remote LoRaWAN temperature and humidity monitoring provide businesses with the ability to take readings and historical logs for compliance audits. Security measures and cost-effective protection are provided by multiple threshold Settings.

15. Water resources management

    Commercial buildings, food and beverage processing plants, óstáin, ollmhargaí, and car washes all produce water waste due to spills, sceitheanna, and equipment damage. Instant notification and response are key to reducing compliance risks while reducing costs. By deploying LoRaWAN metering systems to replace outdated labor-intensive processes, the water management solution, consisting of LoRaWAN sensors, provides municipalities with a detailed total water footprint. Smart water meter solutions enable remote access to usage data and billing accounts, improving operational efficiency and generating additional service revenue.

16. Trash can monitoring

    The system automatically sensed and monitored locations, bin filling levels, and extraction frequencies, enabling fleet operators to manage the status of work orders in real-time, and reduce labor costs. LoRaWAN-based waste monitoring solutions reduce collection expense and time. Automatic notification alerts provide smart route planning for collection service providers when bins reach a predefined threshold and eliminate unnecessary access and overflow bins for end users.
