Three Phase Multi Tariff Lora Smart Meter Remote Meter Reading in LoraWan Technology


Working Principle

Measured AC voltage and current have been sampled and transported to professional metering chip, after digital processing, they have been changed to the pulse signal, which in direct proportion to active power, and then sent to microprocessor. Microprocessor would accumulate the pulse signal according to the tariff, then get total power and tariff power and put them in register. At the same time, the microprocessor finishes the function of display and changeover with external messages. Please take attention to the Figure 1


Technical Features

  • Take advanced professional integrated circuit and SMT, hot air reflow soldering and wave soldering as technical design, which can make sure of reliable quality.
  • Take three units isolated power for metering unit, data processing unit and communication interface unit. All the output signals are handled by optoelectronic isolation, which can increase Electromagnetic Compatibility, and also confirm the stable working for metering unit, that will not influence by communication interface.
  • Wide voltage range from 154V to 265V, and won’t be damaged even on 418V, which upgrade its environmental suitability.
  • Build in “Watch Dog” design for microprocessor, to promise for the well working of CPU. Triple backup for metering data. The data are safe even in harsh conditions.
  • Fully sealed dustproof and waterproof design, material of cover has excellent flame retardant and anti-corrosion, anti-aging properties.
  • Build in clock circuit with temperature compensation function, the function can also work when power off and get power source from battery, to make sure of the high processing precision of clock.
  • With standard interface of Lora communication module, support for Lora communication..
