Description
BREZŽIČNI IN BREZBATERIJSKI MODUL ZA ZAZNAVANJE STANJA DELOVANJA ELEKTRIČNIH NAPRAVWIRELESS AND FREE BATTERY MODULE FOR DETECTION OF STATE OF OPERATION OF ELECTRICAL DEVICES
Predmet izuma je brezžični in brezbaterijski modul za zaznavanje stanja delovanja električnih naprav, ki omogoča nadzor nad stanjem priključenih naprav preko inštalacije. Modul po izumu je zasnovan na zajemanju podatkov (padca napetosti, velikosti toka, temperature, vlage ipd.), prednostno padca napetosti na inštalacijskem zaščitnem sredstvu in omogoča zaznavo spremembe (odklopa ali drugih sprememb) in identifikacijo, kje oz. na katerem zaščitnem sredstvu je prišlo do spremembe (odklopa ali drugih sprememb), poleg tega pa je z njim omogočen tudi nadzor delovanja nadzorovane naprave (nadzorovana naprava je naprava, ki je priključena v električnem tokokrogu, katerega inštalacijsko zaščitno sredstvo varuje), saj se lahko preko brezžičnega signala prenašajo še različni merilni rezultati tako, da predstavlja npr. z uporabo RFID komunikacije učinkovito in cenovno zelo sprejemljivo rešitev nadzora stanja delovanja električnih naprav.The subject of the invention is a wireless and battery-free module for detecting the state of operation of electrical devices, which allows monitoring the status of connected devices through installation. The module according to the invention is based on data capture (voltage drop, current size, temperature, humidity, etc.), preferably a voltage drop on the installation protection device and allows the detection of a change (disconnection or other changes) and identification of where or. on which protective device there has been a change (disconnection or other changes), it also enables the operation of a controlled device to be controlled (a controlled device is a device connected in an electrical circuit whose installation protection device is protected), since Different measurement results are transmitted over the wireless signal such that, e.g. using RFID communication, an efficient and cost-effective solution for controlling the status of electrical devices.
Tehnični problem, ki ga predložen brezžični in brezbaterijski modul za zaznavanje stanja delovanja električnih naprav po izumu uspešno rešuje, je zagotovitev enostavnega, brez večjih posegov v nadzorovano napravo, nadzora nad električno napravo v smislu njene porabe oz. samegaA technical problem that the presented wireless and battery-free module for detecting the state of operation of electrical devices according to the invention is successfully solved is the provision of simple, without major interference with the controlled device, control of the electrical device in terms of its consumption or. alone
delovanja naprave, ter ob dodanih ustreznih elementih tudi vplivanje na delovanje same naprave.the operation of the device, and with the addition of appropriate elements, also affect the operation of the device itself.
Brezžični in brezbaterijski modul za zaznavanje stanja delovanja električnih naprav po izumu je namenjen delovanju v tako imenovanih »pametnih omrežjih«. Znane so rešitve, ki obstajajo na trgu in omogočajo nadzor nad priključeno napravo tako, da uporabnik namesti »monitoring« napravo v tokokrog kot dodatno napravo t.i. »add-on device«.The wireless and battery-free module for detecting the state of operation of electrical devices according to the invention is intended to operate on so-called "smart networks". There are known solutions that exist on the market that allow control of a connected device by installing a monitoring device in the circuit as an additional device, i.e. "Add-on devices".
Tako je v dokumentu W02005/101604 principielno opisana rešitev, kjer bi zaščitna naprava, ki sestavlja odklopnik, imela brezžično komunikacijo do lokalizirane računalniške naprave. Preko te povezave se lahko prenašajo električne veličine, nastavitveni parametri varovalne funkcije ali pa diagnostika sistema, odklopnika ali pa zaščitne naprave same. Izvedba ne omenja brezbaterijskega napajanja ter ne opredeljuje natančno zajema podatkov in mehanske rešitve, kjer naj bi bilo vse integrirano v samem odklopniku /releju.Thus, document W02005 / 101604 describes in principle a solution where a circuit breaker constituting a circuit breaker would have wireless communication to a localized computer device. Through this connection, electrical quantities, setting parameters of the protective function or the diagnostics of the system, circuit breaker or the protective device itself can be transmitted. The design does not mention battery-free power supply and does not accurately capture data and mechanical solutions where everything should be integrated into the circuit breaker / relay itself.
Dokument EP 1975967 opisuje stikalno napravo oz. zaščitno napravo z brezžično komunikacijo z nadzorovano napravo, za npr. motor. Brezžična komunikacija je namenjena za upravljanje s stikalom, kot tudi za zbiranje informacije o stanju bremena. Izvedba ne rešuje brezbaterijskega napajanja preko komunikacije, vsebuje pa napajanje iz glavne linije (vezava v serijo in zajema galvansko ločen induktivni ali kapacitivni vir napajanja).EP document 1975967 describes a switchgear or device. a security device with wireless communication with a controlled device, e.g. engine. Wireless communication is intended to operate the switch as well as to collect load status information. The design does not solve battery-free power via communication, but contains power from the main line (bundling and capturing a galvanically separate inductive or capacitive power source).
V dokumentu WO2011/118007 je opisana izvedba zaščite prenosa podatkov na zbirno mesto. Prenašajo se podatki o stanju npr. solarnega generatorja (moč in efektivna poraba) za kompleksnejšo obdelavo v serverju ali nadzornem center-u. Tudi ta rešitev ne vsebuje brezbaterijskega koncepta in ne omenja zaščitne naprave.Document WO2011 / 118007 describes the implementation of data transmission security at the collection point. Status information is transmitted e.g. solar generator (power and effective consumption) for more complex processing in the server or control center. Also, this solution does not contain a battery free concept and does not mention a protective device.
V dokumentu US2006/0190198 je opisana rešitev, ki rešuje tehnični problem pridobivanja posamezne električne informacije od vsakega električnega aparata z merjenjem njegovih lastnosti (moč, napetost, tok, vlaga), neodvisno od njegove lokacije. Nadzorna/prenosna naprava io vsebuje A/D pretvornike za pretvorbo in procesor za obdelavo. Opisani izum opredeljuje predvsem obdelavo signalov in se ne poglablja v samo tehnično izvedbo kako do takega podatka priti - ga izmeriti. Omenjen je napetostni senzor, tokovni senzor in temperaturni senzor, ki so nameščeni v okolici naprave, katere analizo porabe želimo spremljati. To je zelo velik is in zmogljiv sistem, ki se od našega izuma razlikuje predvsem v velikosti in ceni.US2006 / 0190198 describes a solution that solves the technical problem of obtaining individual electrical information from each electrical appliance by measuring its properties (power, voltage, current, humidity), regardless of its location. The io control / port device contains A / D converters for conversion and a processor for processing. The present invention defines primarily signal processing and does not go deep into the technical implementation of how to obtain such data. Mention is made of the voltage sensor, the current sensor and the temperature sensor, which are located in the vicinity of the device whose consumption analysis we want to monitor. It is a very large and powerful system that differs from our invention mainly in size and price.
Patentna dokumenta JP2003050620 in US2006/0176630 opisujeta zaščito ideje nadzornega sistema, ki je sposoben brezžično komunicirati med nadzorno enoto in mobilno opremo. Nadzorna enota zbira podatke iz naprave, na katero je priključena ter pretvarja podatke v digitalno obliko. Prenosni terminal je namenjen za zbiranje podatkov iz nadzornih enot. Splošna vloga, ki zopet ščiti le prenos informacije. DokumentJP2003050620 and US2006 / 0176630 describe the protection of the idea of a control system capable of communicating wirelessly between the control unit and the mobile equipment. The control unit collects data from the device to which it is connected and converts the data to digital format. The portable terminal is designed to collect data from control units. A general application that only protects information transfer again. The document
US2006/0176630 nadalje vsebuje nadzorno napravo v elektronski komunikaciji z odklopnikom ter sprejemno napravo, nameščeno ločeno od nadzorne naprave. Nadzorna naprava sprejema podatke iz odklopnika (eno ali več fazno merjenje toka v omrežju, ki ga odklopnik ščiti, merimo tudi temperaturo okolice in merimo tudi trip stanja odklopnika) in jih brezžično pošilja. Nadzorna naprava je nameščena neposredno na inštalacijski odklopnik. Tudi ta rešitev se razlikuje od pričujočega izuma glede napajanja. Modul pridobiva napajanje iz odklopnika, ko je ta v zaprtem stanju in iz baterije, ki jo je možno polniti, medtem ko je io odklopnik v odprtem stanju, kar pomeni, da je napajalno vezje vezano v seriji. Namen naprave po tem dokumentu je spremljanje delovanja samega odklopnika (njegovega toka, temperature in stanja ob pojavu odklopa), medtem ko naš izum omogoča predvsem spremljanje stanja bremena, torej kvalitativni in nadzorni sistem.US2006 / 0176630 further comprises a monitoring device in electronic communication with a circuit breaker and a receiving device mounted separately from the monitoring device. The control unit receives data from the circuit breaker (one or more phase current measurements in the network protected by the circuit breaker, also measures the ambient temperature and also measures the trip status of the circuit breaker) and sends it wirelessly. The control unit is mounted directly on the circuit breaker. Again, this solution is different from the present invention regarding power supply. The module receives power from the circuit breaker when the circuit breaker is in the closed state and from a rechargeable battery while the io circuit breaker is in the open state, which means that the power circuit is connected in series. The purpose of the device according to this document is to monitor the operation of the circuit breaker itself (its current, temperature, and condition upon the occurrence of a trip), while our invention primarily enables the monitoring of the load state, that is, the qualitative and control system.
Patentni dokument WO2011/103593 opisuje izvedbeno rešitev merjenja porabe energije, bolj specifično merjenja električne energije preko individualnega odklopnika, oz. se nanaša na električno napravo z neinvazijskim in samo-napajalnim senzorjem za merjenje električnega toka preko glavne linije (lahko je tudi močnostna linija preko odklopnika).Patent document WO2011 / 103593 describes an implementation solution for measuring energy consumption, more specifically measuring electricity through an individual circuit breaker, or. refers to an electrical device with a non-invasive and self-powered sensor for measuring current through the main line (it may also be a power line via a circuit breaker).
Ob spremembi bremena npr. na vtičnici, senzor, nameščen na odklopniku, pripravi indikacijo spremembe moči (porabe) uporabniku. Podatki se lahko zbirajo tudi v centralnem serverju za kasnejšo uporabo. Glavna razlikaWhen changing the load, e.g. on the socket, the sensor mounted on the circuit breaker gives an indication of the change in power (consumption) to the user. Data can also be collected from a central server for later use. The main difference
glede na naš izum je v tem, da se samonapajalni senzor napaja iz glavne linije in ne iz RF signala, preko katerega se prenašajo podatki. Rešitev po našem izumu deluje tudi takrat, ko glavna linija ni napajana, oziroma ni toka. (breme v okvari, odklopnik v odprti poziciji,...). Naš izumu zagotavlja meritev toka v vsakem trenutku (pa čeprav je OA) oz. imamo informacijo o stanju delovanja naprav, ki jih odklopnik, na katerega je nameščen senzor, ščiti.According to our invention, the self-charging sensor is fed from the main line and not from the RF signal through which the data is transmitted. The solution according to our invention also works when the main line is not powered or there is no current. (failure load, breaker in open position, ...). Our invention provides current measurement at all times (even though it is OA) or. we have information about the operation status of the devices that the circuit breaker on which the sensor is mounted protects.
Glavna filozofija pametnih omrežij je naravnana tako, da se potrošnja električne energije prilagaja proizvedeni električni energiji in ne obratno, kot je veljalo doslej. Za ta namen moramo imeti pod nadzorom potrošnjo energije, da ta ne bi bila večja, kot je njena proizvodnja, saj bi v tem primeru nastal električni mrk, kar pa se absolutno ne sme zgoditi. Zaradi tega je potrebno poleg merjenja skupne porabe energije s kalibriranim in certificiranim števcem še dodatno sprotno merjenje porabe (toka, moči) v is posameznem tokokrogu.The main philosophy of smart grids is to adjust the consumption of electricity to the electricity produced, and not vice versa, as was the case before. For this purpose, we need to have energy consumption under control so that it does not exceed its production, since in this case an electrical eclipse would occur, which should absolutely not happen. For this reason, in addition to measuring the total energy consumption by a calibrated and certified meter, it is necessary to additionally measure current consumption (current, power) in and with each circuit.
Standardne talilne varovalke oz. zaščitna stikala v električnih napravah in omrežjih so zasnovana tako, da v primeru predolgotrajne preobremenitve ali kratkega stika, samodejno prekinejo tokokrog v katerega so vključene in s tem preprečijo poškodovanje inštalacije (vodnikov), njihovo pregrevanje in s tem grožnjo varnosti ipd. Pri tem pa se pojavlja problem detekcije odklopa, predvsem kateri del omrežja je bil preobremenjen in zakaj. Dosedanji sistemi so reševali detekcijo odklopa inštalacijskihStandard fuses or fuses. protection switches in electrical devices and networks are designed to automatically break the circuit in which they are plugged in, in the event of prolonged overload or short circuits, thereby preventing damage to the installation (conductors), overheating, and thus a threat to safety, etc. In doing so, there is the problem of detecting disconnections, notably which part of the network was congested and why. Previous systems have addressed the detection of installation disconnections
zaščitnih naprav s posebnimi krmilniki, z zunanjimi, dodatnimi napravami, vgrajenimi senzorji ipd. V omrežjih v katerih so vgrajene transformatorske postaje, razdelilniki ipd. v primeru napake, oz. porušitve omrežja, sicer inštalacijska zaščitna sredstva preprečijo nadaljnjo škodo, je pa težko določiti točno mesto, oziroma točno tisto inštalacijsko zaščitno napravo, na kateri je prišlo do izklopa. Ob tem pa seveda niso na voljo podatki o delovanju omrežja, ki so pomembni za detekcijo in odpravo problema. Brezžični in brezbaterijski modul A,B za zaznavanje stanja delovanja električnih naprav po izumu, ki je priključen na inštalacijsko zaščitno sredstvo C, lahko v njegovi enostavni izvedbi kot modul A le zaznavamo delovanje in/ali prenehanje delovanja inštalacijskega zaščitnega sredstva C, v zahtevnejši izvedbi kot modul B pa lahko izvajamo tudi nadzor nad parametri nadzorovane naprave D in tudi vplivamo na njeno delovanje. Izum bomo podrobneje obrazložili na osnovi izvedbenega primera in is pripadajočih slik, od katerih kaže:protection devices with special controllers, with external, auxiliary devices, built-in sensors, etc. In networks where transformer stations, distributors, etc. are installed. in case of error, or network breakdowns, while installation protection means prevent further damage, but it is difficult to determine the exact location, or exactly, of the installation protection device on which the shutdown occurred. At the same time, however, there is no information available on network performance that is important for detecting and correcting the problem. The wireless and battery-free module A, B for detecting the state of operation of electrical devices according to the invention, which is connected to the installation protection means C, in its simple implementation, as module A, can only detect the operation and / or termination of operation of the installation protection means C, in a more sophisticated version than module B, we can also control the parameters of controlled device D and also affect its operation. The invention will be explained in greater detail on the basis of an embodiment and with the accompanying drawings, of which:

Najprimernejše mesto za namestitev brezžičnega in brezbaterijskega modula A,B za zaznavanje stanja delovanja električnih naprav D po izumu je v razdelilni omarici na posameznem zaščitnem sredstvu C (varovalka, odklopnik, stikalo, itd.).The most appropriate location for installing the wireless and battery-free module A, B for detecting the operating state of electrical devices D according to the invention is in the distribution box on the individual protective device C (fuse, circuit breaker, switch, etc.).
io Namensko lahko pri vgradnji modula A,B po izumu ločimo dve skupini in sicer za potrebe pametnih zaščitnih inštalacijskih naprav (odklopnikov in varovalk) ali pa kot dodatno samostojno napravo. V prvem primeru se lahko že pri proizvajalcu v proizvodnji vgradi v posamezen zaščitni aparat ustrezni večnamenski pametni modul po izumu. V drugem primeru pa je le-ta lahko izveden kot dodatna samostojna naprava, tako da se ga lahko priključi na dovodno in odvodno stran inštalacijskega zaščitnega sredstva C, ali katerokoli drugo ekvivalentno mesto, ki omogoča izvedbo meritve. Glede na funkcionalnost, je lahko brezžični in brezbaterijski modul A,B za zaznavanje stanja delovanja električnih naprav po izumu izveden kotio It is purposeful to separate two groups when installing Module A, B according to the invention, either for the purposes of smart protective installation devices (circuit breakers and fuses) or as an additional standalone device. In the first case, the corresponding multifunctional smart module according to the invention can already be installed in the manufacturing unit in an individual protective device. In the second case, it may be implemented as an additional standalone device, so that it can be connected to the inlet and outlet side of the installation protective device C, or any other equivalent location that allows the measurement to be carried out. Depending on the functionality, the wireless and battery-free module A, B for detecting the operating state of the electrical devices of the invention can be implemented as
2o modul A, ki opravlja funkcijo detekcije stanja (ali je varovalka prekinjena ali ne) oziroma modul B, preko katerega lahko pridobimo tudi podatek o toku preko zaščitnega sredstva, pri čemer lahko z modulom B tudi generiramo2o module A, which performs the function of detecting the state (whether the fuse is broken or not) or module B, through which we can also obtain information about the flow through the protective means, with which module B can also be generated
signal za aktuator, ki na našo željo opravi vklop ali izklop inštalacijskega zaščitnega sredstva. Modul B je aktivno vezje in potrebuje napajanje, zaradi česar iz tega naslova izhaja potreba po nevtralnem vodniku oz. po dodatnem napajanju. Nevtralni vodnik lahko nadomestimo z baterijskim napajanjem ali pa napajamo modul B kar preko RFID omrežja (EM polje napaja modul brezžično npr. RFID-PALFI, RFID UHF, NFC) ali kateregakoli drugega ekvivalentnega sredstva.an actuator signal which, at our request, switches the installation protective device on or off. Module B is an active circuit and requires power, which is why the need for a neutral conductor or a conductor is required. after extra power. The neutral conductor can be replaced by battery power or the module B can be fed directly through the RFID network (the EM field is powered by the module wirelessly eg RFID-PALFI, RFID UHF, NFC) or any other equivalent.
Slika 1 prikazuje priključno blok shemo priključitve brezžičnega in brez baterijskega modula A,B po izumu, ki je priključen na sponki io inštalacijskega zaščitnega sredstva C (odklopnika ali varovalnega vložka) in preko vgrajenega komunikacijskega vezja posreduje informacijo o stanju nadzorovane električne naprave D preko brezžične povezave nadzorni enoti E. Glede na vrsto zajetih podatkov (padca napetosti, velikosti toka, temperature ipd.) je lahko brezžični in brezbaterijski modul is A,B za zaznavanje stanja delovanja električnih naprav po izumu priključen na inštalacijsko zaščitno sredstvo C vzporedno ali zaporedno (kot je prikazano na sliki 1 črtkano). Vrsta in količina posredovanih informacij je odvisna od izvedbe samega modula A,B po izumu. Tako je na sliki 2 prikazana izvedba brezžičnega in brezbaterijskega modula za zaznavanje stanja delovanja električnih naprav po izumu v enostavnejši izvedbi kot modul A. Z njim lahko zaznavamo delovanje in/ali prenehanje delovanja zaščitne naprave, ki jo nadzorujemo. Modul A je sestavljen iz vezja 2 zaFigure 1 shows a terminal block diagram of the connection of a wireless and non-battery module A, B according to the invention, which is connected to the terminal io of the installation protection means C (circuit breaker or fuse) and transmits the status of the controlled electrical device D via a built-in communication circuit via a wireless connection control unit E. Depending on the type of data captured (voltage drop, current size, temperature, etc.), the wireless and battery-free module is A, B for detecting the operating state of the electrical devices according to the invention can be connected to the installation protective device C in parallel or in series (such as shown in Figure 1 dashed). The type and amount of information provided depends on the implementation of module A, B according to the invention. Thus, Figure 2 shows an embodiment of a wireless and battery-free module for detecting the state of operation of electrical devices according to the invention in a simpler embodiment than module A. It can detect the operation and / or termination of the protective device being monitored. Module A consists of a circuit 2 for
obdelavo in prilagoditev signala, komunikacijskega vezja 3 in ustrezne oddajne antene 4 ter je preko terminalskega dela 1 priključen na sponki zaščitne inštalacijske odklopne naprave. Delovanje modula A je enostavno, ker ne potrebuje posebnega napajanja. Dovolj je že napajanje preko komunikacijskega kanala (pasivni RFID).processing and adjusting the signal, communication circuit 3 and the corresponding transmit antenna 4, and is connected via a terminal part 1 to the terminals of the protective installation disconnect device. Module A is easy to operate because it requires no special power. Enough power through a communication channel (passive RFID) is enough.
Delovanje modula A bomo pojasnili na konkretnem izvedbenem primeru. Pri prekinitvi zaščitnega sredstva, zaradi izklopa ali prekinitve talilne varovalke, se preko terminalskega dela 1 prenese sprememba napetosti iz sponk zaščitnega sredstva. Ta sprememba napetosti, preko terminalskega io dela 1, vpliva na delovanje vezja 2. Ta del signal digitalizira in prilagodi za naslednjo stopnjo, t.j. komunikacijsko vezje 3, ki preko prilagojene oddajne antene 4 pošilja brezžični signal. Preko komunikacijskega vezja 3 in oddajne antene 4 lahko dobimo tudi potrebno napajanje za pravilno delovanje celotnega vezja po sliki 2.The operation of Module A will be explained in a specific implementation example. When the protective device is interrupted due to switching off or interruption of the fuse, a voltage change from the protective device terminals is transmitted through the terminal part 1. This change in voltage, via terminal io part 1, affects the operation of circuit 2. This part digitizes and adjusts the signal for the next stage, i.e. a communication circuit 3 that transmits a wireless signal through a adapted transmit antenna 4. Through the communication circuit 3 and the transmit antenna 4, we can also obtain the necessary power for the proper operation of the entire circuit according to Figure 2.
Na sliki 3 je prikazana izvedba brezžičnega in brezbaterijski modula za zaznavanje stanja delovanja električnih naprav po izumu v izvedbi kot modul B. Z njim lahko izvajamo nadzor nad parametri nadzorovane naprave in tudi vplivamo na njeno delovanje. Modul B sestavljajo vezje 2 za obdelavo in prilagoditev signala, procesor 8, ojačevalna visokoimpedančna predstopnja 7, gonilnik za aktuator 6, napajalnik 5, komunikacijsko vezje 3 in ustrezna oddajna antena 4. Pri modulu BFigure 3 shows an embodiment of a wireless and battery-free module for detecting the state of operation of electrical devices according to the invention in the form of module B. It can control the parameters of a controlled device and also affect its operation. Module B consists of a signal processing and adjustment circuit 2, a processor 8, a high impedance gain amplifier 7, an actuator driver 6, a power supply 5, a communication circuit 3, and a corresponding transmit antenna 4. In Module B,
predstavlja terminalski del 1 vhode za meritve, terminalski del 9 pa izhod za aktuator.the terminal part 1 represents the inputs for the measurements and the terminal part 9 represents the output for the actuator.
Ojačevalna visokoimpedančna predstopnja 7 zagotavlja ustreznost signala za kasnejšo obdelavo in procesiranje. Z njo lahko na neinvazivni način pridemo do uporabnega signala na inštalacijskem zaščitnem sredstvu, ne da bi vplivali na njeno delovanje (varnost za uporabnika, visoka prebojna trdnost,...). Napajanje je lahko baterijsko, preko napajalnika 5, ali pa je dovedeno preko komunikacijskih kanalov terminalskega dela 9, ali pa kateregakoli drugega načina za zajem io energije.The high impedance step 7 amplifier ensures the signal is suitable for later processing and processing. It can be used in a non-invasive manner to obtain a useful signal on the installation protection device without affecting its operation (safety for the user, high penetration strength, ...). The power can be battery operated, via the power supply 5, or it can be supplied through the communication channels of terminal part 9, or any other way of capturing energy.
Delovanje modula B bomo pojasnili na konkretnem izvedbenem primeru. Pri prekinitvi tokokroga v inštalacijskem zaščitnem sredstvu, se preko terminalskega dela 1 zazna sprememba merjene veličine. Spremembo merjene veličine lahko povzroči tudi padec napetosti na zaščitnem is sredstvu, ki pa je odvisen od toka v tokokrogu, v katerega je vezano zaščitno sredstvo. Zaradi varnosti in pravilnega delovanja tudi ob motnjah, je za terminalskem delu 1 nameščena visokoimpedančna prilagoditvena ojačevalna stopnja 7. Nalogo obdelave, prilagoditve in vzorčenja signala opravlja vezje 2 po sliki 3. Za usklajeno delovanje tega pametnega univerzalnega merilnega principa skrbi procesorska enota 8.
