Abstract
Description
Spôsob amplitúdovej modulácie na účely prenosu informácie vo výkonovom vedení 230V a zapojenie na uskutočňovanie tohto spôsobu.A method of amplitude modulation for the purpose of transmitting information in a 230V power line and engaging to carry out the method.
Oblasť technikyTechnical field
Technické riešenie sa týka rozvádzačov, napájacieho vedenia, spotrebičov a komunikácie medzi nimi po spoločnom sieťovom napájaní. Ide hlavne o reguláciu intenzity osvetlenia bez použitia ovládacieho vedenia.The technical solution concerns switchboards, power lines, appliances and communication between them through a common mains supply. It is mainly the regulation of the light intensity without the use of a control line.
Doterajší stav technikyBACKGROUND OF THE INVENTION
V súčasnosti sa na prenos informácií používa riešenie modulovanej vyššej frekvencie superponovanej na sieťovom napätí.Currently, a modulated higher frequency solution superimposed on the mains voltage is used to transmit information.
Nedostatkom tohoto riešenia je, že vyššie superponované frekvencie si vyžadujú kvalitné rozvody napájania. Ďalej si vyžadujú definované elektrické oddelenie rezonančnými obvodmi. Spätná komunikácia medzi spotrebičom a zdrojom je komplikovaná a realizovateľná len s vyššími nákladmi. Iné riešenie spočíva v samostatnom riadiacom vedení.The disadvantage of this solution is that higher superimposed frequencies require quality power distribution. Furthermore, they require defined electrical separation by resonant circuits. The return communication between the appliance and the source is complicated and feasible only at higher cost. Another solution consists in a separate management line.
Podstata technického riešeniaThe essence of the technical solution
Podstata technického riešenia spočíva v amplitúdovej modulácií a demodulácií napájacieho napätia . V elektrickom rozvádzači, odkiaľ je vedený rozvod napájacieho vedenia sa nachádza modulátor. Ten mení amplitúdu výstupného napájacieho napätia podľa zvoleného protokolu synchrónne s frekvenciou siete. Počet úrovní amplitúdovej modulácie môže byť rôzny. Pre daný účel sa využívajú s výhodou dve úrovne. Pôvodná a znížená o cca 5%. Bitové slovo tvorí kombinácia znížených a neznížených polperiód napájacieho napätia s konečným, definovaným počtom. Moduluje sa len jedna polperióda. Kladná alebo záporná. Druhá polperióda je nezmenená a slúži ako referencia pre vyhodnocovací obvod na strane spotrebiča. Referenciu potrebujeme z dôvodov kolísania napájacieho napätia. Zvoľme si ako referenčnú zápornú polperiodu a dátovú kladnú. Vyhodnocovací obvod porovnáva tieto polperiódy. Kontroluje vždy každú zápornú a hneď s ňou porovnáva nasledujúcu kladnú. Ak sú rovnaké nič sa nedeje. Ak po zápornej nasleduje zmenšená kladná, spúšťa sa register s definovaným počtom bitových miest. V prípade osem bitového slova to bude osem miest. Kladnej polperióde po spustení registra sú priradené úrovne takto: rovnaká kladná polperióda má úroveň logickej nuly a znížená má úroveň logickej jedničky. Po zaplnení registra, ktorého taktovacia frekvencia je synchronizovaná sieťovým napätím sa data odošlú ďalej na spracovanie a vykonanie úkonu, napríklad zníženie intenzity svetelného zdroja. Bitové slovo môže mať rôznu dĺžku a môže obsahovať rôzne inštrukcie. Ako referenčná hodnota sieťového napätia sa môže použiť hodnota, ktorá predchádzala spusteniu registra.The essence of the technical solution lies in the amplitude modulation and demodulation of the supply voltage. A modulator is located in the electrical switchboard from where the power line is routed. It changes the amplitude of the output supply voltage according to the selected protocol synchronously with the network frequency. The number of amplitude modulation levels may vary. Two levels are preferably used for this purpose. Original and reduced by about 5%. The bit word is a combination of reduced and unreduced supply voltage half-periods with a finite, defined number. Only one half period is modulated. Positive or negative. The second half-period is unchanged and serves as a reference for the evaluation circuit on the appliance side. Reference is needed due to fluctuations in supply voltage. Let's choose a negative half-period and a data positive. The evaluation circuit compares these half-periods. It always checks each negative and immediately compares the following positive. If they are the same nothing happens. If negative is followed by a reduced positive, the register is started with a defined number of bit places. In the case of an eight bit word, it will be eight places. The positive half-period after the registry is started is assigned levels as follows: the same positive half-period has a logical zero level and the lowered one has a logical one level. When the register is filled, whose clock frequency is synchronized by the mains voltage, the data is forwarded to the processing and operation, for example to reduce the intensity of the light source. The bitword may have different lengths and may contain different instructions. The value that preceded the start of the register may be used as the mains voltage reference.
Amplitúdová modulácia a demodulácia s porovnávaním hodnoty referenčného napätia má vyššiu odolnosť voči poruchám na sieti.Amplitude modulation and demodulation with a reference voltage value comparison have higher fault tolerance.
Takýto spôsob komunikácie je vhodné použiť na reguláciu osvetlenia či už vnútorného, alebo vonkajšieho. Nie je potrebné žiadne ďalšie vedenie. Po výkonovom vedení sa tieto informácie spoľahlivo dostanú na patričné miesto.Such a method of communication is useful for regulating the lighting, either internal or external. No additional guidance is required. After the power line, this information reliably gets to the right place.
Prehľad obrázkovImage overview
Na obr.l je vyobrazená principiálna schéma zapojenia amplitúdovej modulácie slúžiacej na prenos informácií po napájačom vedení. Na obr.2, obr.3, obr.4 sú znázornené možné spôsoby amplitúdovej modulácie a vyhodnocovania informácie.FIG. 1 is a schematic circuit diagram of amplitude modulation for information transmission over a power line. 2, 3, 4 show possible methods of amplitude modulation and information evaluation.
Príklady uskutočnenia technického riešeniaExamples of technical solution
Zapojenie na uskutočnenie spôsobu amplitúdovej modulácie na obr.l pozostáva z bloku i modulátor, bloku 2 demodulátor, bloku 3 výkonová riadiaca jednotka, bloku 4 spotrebič, pričom blok 3 výkonová riadiaca jednotka a blok 4 spotrebič sú navzájom prepojené. Blok i modulátor je spojený s blokom 2 demodulátor vedením 5.The circuitry for carrying out the amplitude modulation method of Fig. 1 consists of a modulator block 1, a demodulator block 2, a power control unit 3, a consumer block 4, wherein the power control unit 3 and the consumer block 4 are interconnected. Both the block and the modulator are connected to the block 2 by the demodulator via line 5.
Na obr.2 je uvedený jeden z možných spôsobov modulácie a demodulácie. V tomto prípade modulátor ovplyvňuje len kladnú polperiódu. Tá nesie inštrukciu o hodnote informácie. Využíva sa dvojstavová modulácia. Ak je špičková hodnota kladnej polperiódy rovnaká ako hodnota zápornej - referenčnej polperiódy, znamená to pre vyhodnocovací obvod logická 0. Ak je špičková hodnota kladnej polperiódy znížená znamená to logická 1. Hodnota kladnej polperiódy sa porovnáva vždy s predošlou zápomou-referenčnou polperiódou. Ak demodulátor identifikuje zníženú kladnú polperiodu automaticky sa spúšťa záznam do registra. Ten zaznamená a uloží data v počte 18. Chod registra je taktovaný frekvenciou siete. Po načítaní potrebného počtu dát, register odovzdá uložené dáta na spracovanie. Dekódovací obvod vyhodnotí došlú sériu logických núl a jedničiek a odovzdá výkonovej riadiacej jednotke.FIG. 2 shows one possible method of modulation and demodulation. In this case, the modulator only affects the positive half-period. This carries an instruction about the value of the information. Two-state modulation is used. If the peak value of the positive half-period is the same as the value of the negative-reference half-period, it means logic 0 for the evaluation circuit. If the demodulator identifies a reduced positive half-period, the record is automatically triggered. It records and saves data in the count of 18. The running of the register is clocked by the network frequency. After reading the necessary number of data, the register transfers the stored data for processing. The decoding circuit evaluates the incoming series of logic zeros and ones and passes it to the power control unit.
