\nAk hovor\u00edme nie o individu\u00e1lnych merac\u00edch pr\u00edstrojoch, ale o t\u00fdch, ktor\u00e9 s\u00fa v pivniciach, kotolniach a na podnikoch, v\u00e4\u010d\u0161ina z nich je teraz vybaven\u00e1 telemetrick\u00fdm v\u00fdstupom. Zriedkavej\u0161ie impulzn\u00fdm, \u010dastej\u0161ie RS-485\/232 alebo Ethernet. Zvy\u010dajne najlukrat\u00edvnej\u0161ie meracie pr\u00edstroje s\u00fa tie, ktor\u00e9 meraj\u00fa teplo. Pr\u00e1ve za ich dispe\u010ding s\u00fa ochotn\u00ed plati\u0165 predov\u0161etk\u00fdm.
\nU\u017e som podrobne hovoril o \u0161pecifik\u00e1ch RS-485 vo svojej predch\u00e1dzaj\u00facej \u010dl\u00e1nku. Ak to zjednodu\u0161\u00edme \u2014 je to len rozhranie na prenos d\u00e1t. V podstate ide o po\u017eiadavky na elektrick\u00e9 impulzy a komunika\u010dn\u00e9 linky. Opis paketov je na vy\u0161\u0161ej \u00farovni, v \u0161tandarde prenosu d\u00e1t, ktor\u00fd funguje nad RS-485. A \u010do za \u0161tandard tam bude \u2014 to je na v\u00fdrobcovi. \u010casto Modbus, ale nie je to povinn\u00e9. Aj ke\u010f je to Modbus, m\u00f4\u017ee by\u0165 aj nieko\u013eko modifikovan\u00fd.<\/p>\n

V podstate pre ka\u017ed\u00fd merac\u00ed pr\u00edstroj potrebujete svoj vlastn\u00fd skript prieskumu, ktor\u00fd vie s n\u00edm 'rozpr\u00e1va\u0165' a zis\u0165ova\u0165 inform\u00e1cie.

Bohu\u017eia\u013e, toto rie\u0161enie pokryje iba \u010das\u0165 na\u0161ich potrieb. Zvy\u010dajne m\u00e1 popul\u00e1rny odpo\u010det nieko\u013eko gener\u00e1ci\u00ed a skript pre ka\u017ed\u00fa gener\u00e1ciu sa m\u00f4\u017ee l\u00ed\u0161i\u0165. Niekedy len trochu, inokedy z\u00e1sadne. Pri k\u00fape nie\u010doho dostanete posledn\u00fa gener\u00e1ciu. U predplatite\u013ea je v\u0161ak s vysokou pravdepodobnos\u0165ou nie\u010do star\u0161ie. To sa u\u017e nepred\u00e1va v obchodoch. A predplatite\u013e nebude meni\u0165 uzol merania. <\/p>\n

Odtia\u013e prich\u00e1dza prv\u00fd probl\u00e9m. P\u00edsanie tak\u00fdchto skriptov je pevn\u00e1 v\u00e4zba medzi v\u00fdvoj\u00e1rmi softv\u00e9ru a in\u017einiermi \u201ena mieste\u201c. K\u00fapili sme posledn\u00fa gener\u00e1ciu, nap\u00edsali sme ak\u00fdsi po\u010diato\u010dn\u00fd \u0161abl\u00f3n a \u010falej sme ho modifikovali u\u017e na re\u00e1lnych zariadeniach. Robi\u0165 to laborat\u00f3rne je nerealistick\u00e9, len pri pr\u00e1ci s \u017eiv\u00fdmi predplatite\u013emi.<\/p>\n

Str\u00e1vili sme ve\u013ea \u010dasu vytv\u00e1ran\u00edm takejto v\u00e4zby. Teraz je algoritmus vyladen\u00fd. Po\u010diato\u010dn\u00e9 \u0161abl\u00f3ny sa neust\u00e1le upravovali a dop\u013a\u0148ali v z\u00e1vislosti od toho, \u010do sme stretli vo svojej praxi. Samozrejme, predplatite\u013ea sme informovali, ak n\u00e1hodou jeho odpo\u010det bol o nie\u010do \u201ein\u00fd\u201c. Pri objaven\u00ed tak\u00e9ho zariadenia sa pripoj\u00ed pod\u013ea \u0161tandardn\u00e9ho sch\u00e9my a skript prieskumu sa modifikuje za behu.

Samotn\u00fd proces integr\u00e1cie je dos\u0165 nepredv\u00eddate\u013en\u00e1 vec. Niekedy je potrebn\u00e9 vykona\u0165 minimum opr\u00e1v.

M\u00f4\u017ee to by\u0165 dokonca sie\u0165ov\u00e1 karta s RJ-45 (v tomto pr\u00edpade je ModBus zabalen\u00fd do Ethernetu). <\/p>\n

Alebo v\u00f4bec ni\u010d. Len hol\u00fd mera\u010d. M\u00f4\u017eeme do neho nain\u0161talova\u0165 rozhranie, ktor\u00e9 pred\u00e1va v\u00fdrobca samostatne a stoj\u00ed peniaze. Hlavn\u00fd probl\u00e9m je v tom, \u017ee na jeho in\u0161tal\u00e1ciu je potrebn\u00e9 otvori\u0165 mera\u010d a zru\u0161i\u0165 pe\u010date.

V z\u00e1vislosti od in\u0161talovan\u00e9ho rozhrania sa vykon\u00e1va \u010fal\u0161ia \u00faprava. Napr\u00edklad, rozhodli sme sa pripoji\u0165 mera\u010d k\u00e1bli. To je najjednoduch\u0161ia mo\u017enos\u0165, ak je v 100-metrovom dosahu n\u00e1\u0161 prep\u00edna\u010d, tak sa s LoRa zaobera\u0165 netreba \u2013 je to zbyto\u010dn\u00e9. Lep\u0161ie je k\u00e1bli pripoji\u0165 do na\u0161ej siete, do izolovanej VLAN.<\/p>\n

Pre RS-485\/232 je potrebn\u00fd prevodn\u00edk na Ethernet. Mnoh\u00ed si hne\u010f spomen\u00fa na MOXA, ale to je drah\u00e9. Pre na\u0161e rie\u0161enia sme vybrali lacnej\u0161ie \u010d\u00ednske rie\u0161enie.<\/p>\n

Ak je v\u00fdstup priamo Ethernet, tak prevodn\u00edk nie je potrebn\u00fd.<\/p>\n

Ot\u00e1zka. Povedzme, \u017ee sami in\u0161talujeme rozhranie. M\u00f4\u017eeme si u\u013eah\u010di\u0165 \u017eivot a hne\u010f v\u0161ade d\u00e1va\u0165 Ethernet?<\/p>\n

Nie v\u017edy je to mo\u017en\u00e9. Treba sa pozrie\u0165 na kon\u0161trukciu skrine. M\u00f4\u017ee sa sta\u0165, \u017ee nebude ma\u0165 potrebn\u00fd otvor, aby sa rozhranie umiestnilo spr\u00e1vne. A mera\u010d, pripom\u00ednam, m\u00e1me v suter\u00e9ne. Alebo v kotolni. Tam je vysok\u00e1 vlhkos\u0165, hermetickos\u0165 sa nesmie poru\u0161ova\u0165. Upravi\u0165 skrinu s\u00fastruhom \u2013 zl\u00e1 idea.

\u010ealej. Je mera\u010d pripojen\u00fd na garantovan\u00e9 nap\u00e1janie? Ak nie, tak \u017eije z bat\u00e9rie. V takom re\u017eime je ur\u010den\u00fd na ru\u010dn\u00e9 vy\u017eiadanie raz za mesiac na tri min\u00faty. Neust\u00e1le vy\u017eadovanie z VKP-7 vybije jeho bat\u00e9riu. To znamen\u00e1, \u017ee treba \u0165aha\u0165 garantovan\u00e9 nap\u00e1janie a umiestni\u0165 meni\u010d nap\u00e4tia.<\/p>\n

T\u00fdmto n\u00e1\u0161 zverinec pokra\u010duje. Ide o to, \u017ee existuje nieko\u013eko typov spr\u00e1v. V podstate odr\u00e1\u017eaj\u00fa to ist\u00e9 (spotrebovan\u00e9 teplo), ale r\u00f4znymi sp\u00f4sobmi.<\/p>\n

V podstate pou\u017e\u00edvaj\u00fa nie jednotn\u00e9 \u0161tandardy, ale zau\u017e\u00edvan\u00fa prax. Boli pr\u00edpady, ke\u010f odberatelia videli v\u0161etky hodnoty, ktor\u00e9 potrebovali (mno\u017estvo spotrebovan\u00e9ho tepla, objem dodan\u00e9ho a odveden\u00e9ho nosi\u010da tepla, rozdiel tepl\u00f4t), ale st\u013apce v spr\u00e1ve neboli v tej spr\u00e1vnej sekvencii.
\nOdtia\u013e nasleduje \u010fal\u0161\u00ed krok \u2014 spr\u00e1va by mala by\u0165 prisp\u00f4sobite\u013en\u00e1. To znamen\u00e1, \u017ee odberate\u013e si s\u00e1m vyberie, \u010do v akej sekvencii ide a ak\u00e9 zdroje s\u00fa v jeho dokumente. <\/p>\n

Tu je zauj\u00edmav\u00fd moment. V\u0161etko je v poriadku, ak je n\u00e1\u0161 merac\u00ed pr\u00edstroj spr\u00e1vne nain\u0161talovan\u00fd.

Stretli sme sa so zariadeniami, ktor\u00e9 si myslia, \u017ee je rok 2010. V na\u0161ej s\u00fastave to bude vyzera\u0165 ako nulov\u00e9 hodnoty k aktu\u00e1lnemu d\u00e1tumu, a skuto\u010dn\u00e1 spotreba \u2014 ak zvol\u00edme rok 2010.

Ja \u00e1no. Ale ako dok\u00e1za\u0165, \u017ee sa v na\u0161om syst\u00e9me ni\u010d nemen\u00ed, \u017ee neskr\u00fdvame hodnoty? To je u\u017e ot\u00e1zka certifik\u00e1cie. Syst\u00e9m dotazovania mus\u00ed ma\u0165 certifik\u00e1t, ktor\u00fd potvrdzuje jeho nestrannos\u0165. V\u0161etky ve\u013ek\u00e9 syst\u00e9my, ako LERS, Ja Energetik a in\u00e9, maj\u00fa tak\u00fdto certifik\u00e1t. Z\u00edskali sme ho aj my, aj ke\u010f je to drah\u00e9 a zabera ve\u013ea \u010dasu.<\/p>\n

Samozrejme, v\u017edy sa d\u00e1 skr\u00e1tka urobi\u0165 a k\u00fapi\u0165 nie\u010do hotov\u00e9. Ale za to sa bude musie\u0165 plati\u0165 developerovi. A developer m\u00f4\u017ee po\u017eiada\u0165 nielen o vstupn\u00fd poplatok, ale aj o mesa\u010dn\u00fd poplatok. Teda budeme n\u00faten\u00ed zdie\u013ea\u0165 s n\u00edm \u010das\u0165 n\u00e1\u0161ho kol\u00e1\u010da.<\/p>\n

Na\u010do to v\u0161etko?<\/h3>\n

\nHlavn\u00fd probl\u00e9m nie je v tom. V\u00fdvoj vlastn\u00e9ho syst\u00e9mu je tie\u017e ve\u013emi drah\u00fd a omnoho \u0165a\u017e\u0161\u00ed. Av\u0161ak, poskytuje d\u00f4le\u017eit\u00fa v\u00fdhodu. Presne ch\u00e1peme, ako to funguje. \u013dahko to \u0161k\u00e1lujeme, m\u00f4\u017eeme to modifikova\u0165, ak sa n\u00e1hle objav\u00ed potreba. Odberate\u013e dost\u00e1va kompletn\u00fd servis, a z na\u0161ej strany sto percentn\u00fd kontrolu nad procesom.<\/p>\n

Pr\u00e1ve preto sme si vybrali druh\u00fa cestu. Investovali sme do nej rok \u017eivota na\u0161ich developerov a poln\u00fdch in\u017einierov. Ale teraz presne ch\u00e1peme pr\u00e1cu celej re\u0165aze.<\/p>\n

Pri sp\u00e4tnom poh\u013eade ch\u00e1pem, \u017ee bez z\u00edskan\u00fdch vedomost\u00ed by som len \u0165a\u017eko interpretoval ne\u0161tandardn\u00e9 spr\u00e1vanie toho alebo onoho po\u010d\u00edtadla. <\/p>\n

Okrem toho, na z\u00e1klade syst\u00e9mu dispe\u010derovania je mo\u017en\u00e9 vybudova\u0165 nie\u010do v\u00e4\u010d\u0161ie. Alarmy na prekro\u010denie spotreby, spr\u00e1va o poruch\u00e1ch. \u010coskoro pripravujeme spustenie mobilnej aplik\u00e1cie. <\/p>\n

I\u0161li sme e\u0161te \u010falej a do na\u0161ej platformy (in\u00e1\u010d to ani nazva\u0165 nejde) sme pridali mo\u017enos\u0165 prij\u00edma\u0165 podnety od obyvate\u013eov, mo\u017enos\u0165 spravova\u0165 na\u0161e \u201einteligentn\u00e9 domof\u00f3ny\u201c, ako aj kontrolu verejn\u00e9ho osvetlenia a nieko\u013eko \u010fal\u0161\u00edch projektov, o ktor\u00fdch som zatia\u013e nep\u00edsal.<\/p>\n

\nTo v\u0161etko je zlo\u017eit\u00e9, mozgov\u00e9 l\u00e1manie a trv\u00e1 to dlho. Ale v\u00fdsledok stoj\u00ed za to. Odberatelia dost\u00e1vaj\u00fa hotov\u00fd komplexn\u00fd produkt. <\/p>\n

Ka\u017ed\u00fd oper\u00e1tor, ktor\u00fd pl\u00e1nuje vstup do sektoru b\u00fdvania, sa ur\u010dite vyberie touto cestou. Prejd\u00fa?
\nToto je ot\u00e1zka. Nejde ani tak o peniaze. Ako som p\u00edsal vy\u0161\u0161ie, potrebuje sa tu naozaj spojenie pr\u00e1ce v ter\u00e9ne a v\u00fdvoja. Nie v\u0161etci ve\u013ek\u00ed hr\u00e1\u010di s\u00fa na to zvyknut\u00ed. Ak va\u0161i v\u00fdvoj\u00e1ri sedia v Moskve a pripojenia sa robia v Novosibirsku, v\u00e1\u0161 \u010das na hotov\u00fd produkt sa v\u00fdrazne predl\u017euje.<\/p>\n

\u010cas uk\u00e1\u017ee, kto na tomto trhu pre\u017eije, a kto povie \u2014 no, na to zapla\u0165! Ale jedno viem ur\u010dite \u2014 pr\u00eds\u0165 a z\u00edska\u0165 podiel na trhu v\u00fdlu\u010dne s peniazmi sa nepodar\u00ed. Tento proces si vy\u017eaduje netradi\u010dn\u00e9 pr\u00edstupy, dobr\u00fdch in\u017einierov, prenikanie do regul\u00e1ci\u00ed, komunik\u00e1ciu so zdrojmi a odberate\u013emi, ako aj neust\u00e1le odha\u013eovanie a prekon\u00e1vanie prek\u00e1\u017eok. <\/p>\n

P. S.<\/b> V tomto \u010dl\u00e1nku som sa z\u00e1merne s\u00fastredil na teplo a nespom\u00ednam elektrinu ani vodu. Taktie\u017e opisujem pripojenie cez k\u00e1bel. Ak m\u00e1me impulzov\u00fd v\u00fdstup \u2014 tam s\u00fa svoje nuansy, ako povinn\u00e9 overenia po in\u0161tal\u00e1cii. M\u00f4\u017ee sa sta\u0165, \u017ee k\u00e1blom sa nedostaneme k miestu, vtedy prich\u00e1dza na rad LoRaWAN. Op\u00edsa\u0165 cel\u00fa na\u0161u platformu a f\u00e1zy jej v\u00fdvoja v jednom \u010dl\u00e1nku je jednoducho nerealistick\u00e9.
