Multi-user meter manufacturers tell you about the data storage technology of the meter:
Multi-user electricity meter with high measurement accuracy, strong overload capacity, low power consumption, stable and reliable performance, small size, light weight, and convenient operation; easy to implement management, and adapted to the needs of different user groups such as industry, agriculture, civil use, etc.
Multi-user electricity meter manufacturers are a kind of electricity data collection instrument based on MCU and a large-scale electricity collection module. Small and powerful, it is welcomed by users in centralized power supply places such as college student dormitories and intelligent communities. For the flexibility of meter usage, there are some programmable parameters, such as meter number, number of metering households, communication rate, meter pulse constant, time value of multiple rate period, power supply status of each household, etc., as well as its metered data, That is, the power consumption of each user. Once these data are disturbed and damaged, not only the meter cannot work normally, but also economic losses to the user and economic disputes. Therefore, the data must be reliable, volatile, and non-volatile.
The power consumption of each user is converted into a pulse amount proportional to the power through a large-scale energy measurement integrated circuit (such as BL0933, ADE7755, etc.). After the photoelectric coupling circuit, the switch input interface is taken into the memory by the CPU According to the collected pulse amount, the CPU accumulates the power consumption of each user, stores it in a non-volatile memory, and the display circuit displays the power consumption of each household in turn. Multi-user electricity meter manufacturers welcome you to consult and understand through the remote communication interface circuit (such as RS485, CAN bus) to achieve remote transmission of measurement data.
