Electricity Gas aqua et calefactio bills sunt propinqua ad omnes vitae et incommoda manualium meter Lectio, ut diu, humilis efficientiam, impropria statistics et altum virgam costs, impropria. Si vos accipere in rationem tempus-of-usus exosculatio ut gradus tariffs et tempus-of-usu tariffs, tum quod potentia qualis (PQ) deprehendatur et realis-tempore culpa metum, quod est omnino impossibile est ad completum manual meter Lectio.
Cum enim progressio scientia et technology, coegi per industria consociationes et major societates, copulata cum macro-control ad Nationallevel, remotis centralized meter legere ratio habet paulatim et in domum suam et foris.
Yint etiam accipit plena commoda sui technology et opibus in tutela cogitationes, et ludit an maximus munus in remotis centralized meter lectionem ratio. Hoc comprehendendo consilia occubuisse praesidio solutions ad ampliorem et secure remotis centralized meter Lectio ratio, pro consilio referatur dolor Meter Amr, Centralizer Design Engineers.
Concentrated metering ratio est fere composito ex quatuor gradus: terminatio dolor metris (aqua, electricae, Gas et calor), collector, ut ostensum est in figura.
Terminatio dolor meter dolor meter est maxime propius ad user, etiam in domum metering, ut dolor metris, aqua metris, Gas metris et calor metra ad calefacit in septentrionali elit.
Figura II Sample diagram dolor electricity, Gas, aqua et calor metris (image online)
Pelagus munus in dolor terminales metrum est ut portare de terminatio metering et feodo imperium administratione, colligendis notitia ex user terminatio in usum electricity, aqua, Gas et calor et ostenderet Feedback Related notitia ad user, ut usus, current gradum, ut user, etc.
The information collected from the user terminal needs to be uploaded in real time (or in sections) from the collector to the server backend, and the management backend also needs to issue relevant fee control or security authentication management instructions, therefore, the smart terminal meter also integrates a communication module, and the common terminal meter adopts communication methods such as RS485, power carrier and infrared. Ut ostensum est in Figura III, ad obstructionum tabula compositionem de dolor meter.
Yint habet certa et completum Circuit praesidio solutions ad virtutem procuratio et communicationis circuits of dolor electricity metris, dolor aqua metris, et habet ad usum et referat in variis test signa, et recellit consiliis et referat a Smart Typis et recellit consiliis et referat a Smart Terminal Meter Design et Reference a Smart Meter Design et Reference.
2.2 COACTOR
Smert terminales metris fere meter per familia et unitas aedificia uti centralized meter institutionem, id est unitas metris in ordine eleganter in unum locum. In hoc casu collectors potest applicari ad colligam notitia ex se meter centraliter. Plerumque a collector est installed nearby, et manages XII, XXXII seu LXIV metris per colligendis meter pulsus vel communicationis modi ut Rs232 (diversis generis collectores potest electus secundum numerum metris per Portitorem ad unitatem.
Hoc potest etiam reducere complexionem et altiore sumptus terminum metra. Ut ostensum est in Figura IV, pelagus munus collector est mittere collectio imperium ad terminum metris et accipere in pre-processionaliter notitia de terminalibus metris ad uploading ad concentrator vel servo nubes via wireless GPRS vel wired modo.
Figura IV obstructionum diagram de components of a remotis centralized metering ratio collector
The collector and the smart terminal meter generally use RS485, power carrier, MBUS and other methods for command and data communication, and the higher-level concentrator can use GPRS, 4G, PSTN, Ethernet, NB-IoT, LoRa and other wired or wireless networks to carry out data communication.
2.3 intentator
Et intenta est centralis administratione et imperium fabrica de remotis centralized meter Lectio ratio. Est reus regularly Lectio terminatio data, ratio mandatum transmissio, notitia communicationis, network procuratio, eventus recording, horizontalis data tradenda et alia munera. Quod munera dividuntur cum supra collector munera.
2.4 Backstage Magister Station (servo, data Management, nubes)
Et Backstage Magister statione adhibetur ad administratione interfaces, ut opus procuratio, data query, præcipiens, etc.
Sicut ostensum est in figura infra, quod architectura et administratione suggestus munera a wireless remotis aqua meter:

III. Tutela Circuit enim remotis COACTOR System
Yint Designs Tutela Solutions ad Hardware Circuitus Terminalis Meters, collectores et concentrsors de remotis COACTOR ratio, providing et efficax electro compatibilibus pericula in clavem, ut potentia copia et signo in clavem, ut potentia copiam et signo in clavem, ut virtus et signo in clavem, ut potentias et signo in clavem, ut potentia et signo interfaces. Pelagus cogitationes sunt:
3,1 voltage sampling et acquisition circuits
Nam dolor metris, voltage signum collectio non requiritur, dum intentione et sampling modi unius-phase et tres-phase metris sunt diversas. In his figure ostendit in voltage acquisition initus terminatio unius-phase metri.
Figura VI Single-Phase Meter Voltage Acquisitionem input
Yint commendat usura varistors in input overVoltage praesidium. Commendatur exempla sunt 14d et 20d products cum voltages de 470v (Una-phase 220v) ~ 820v (Tres-Phase 380V):
