Multi user combined multi rate electricity meter

Multi user combined multi rate electricity meterIt has high measurement accuracy, strong overload capacity, low power consumption, stable and reliable performance, small size, light weight, and easy operation; Easy to manage and adapt to the needs of different user groups such as industrial, agricultural, and civilian electricity measurement.

Multi user electricity meter manufacturers are a type of electricity data collection surface composed of MCU as the center and large-scale electricity collection modules. They have functions such as multi-user electricity collection, long-distance data transmission, user power supply control, and multi rate electricity metering. They are small in size and strong in function, and are popular among users in centralized power supply places such as university student dormitories and intelligent communities. To improve the flexibility of appearance usage, there are some programmable parameters, such as appearance number, number of metering households, communication rate, meter pulse constant, time value during multiple rate periods, power supply status of each household, as well as their metering data, namely the electricity consumption of each user. Once these data are disturbed and damaged, not only will they not function properly on the surface, but they will also cause economic losses to users and trigger economic disputes. Therefore, it is necessary to ensure the reliability, reliability, and non volatility of the data.

The electricity consumption of each user is converted into a pulse quantity proportional to the electricity consumption through large-scale energy metering integrated circuits (such as BL0933, ADE7755, etc.). After passing through the photoelectric coupling circuit, it is collected into memory by the CPU through the switch input interface. The CPU accumulates the electricity consumption of each user based on the collected pulse quantity, stores it in non-volatile memory, and displays the electricity consumption of each household alternately through the display circuit. The long-distance transmission of measurement data is completed through long-distance communication interface circuits (such as RS485, CAN bus).
