Data Storage Technology of Electricity Meter
The multi-user electricity meter has the advantages of high measurement accuracy, strong overload capacity, low power consumption, stable and reliable performance, small size, light weight, and convenient operation.
The multi-user meter manufacturer is a kind of electricity data acquisition instrument composed of MCU as the core and large-scale electricity acquisition module. It has advanced functions such as multi-user power collection, data remote transmission, user power supply control, and multi-rate power metering. Small size and strong function, it is very popular among users in centralized power supply places such as university student dormitories and intelligent communities. The remote meter reading system directly implements the remote automatic meter reading function in the central control room and can form a regional meter reading network centered on the central control room. Since the antenna fixed-point communication is used, after the installation height is completed according to the technical requirements, 24h communication can be carried out, and it is not affected by the fluctuation of the power grid. To improve the flexibility of the use of the meter, there are some programmable parameters, such as the number of the meter, the number of measuring households, the communication rate, the pulse constant of the meter, the time value of the multi-rate period, and the power supply status of each household. And its metered data, that is, the electricity consumption of each user. Once these data are disturbed and destroyed, not only will the instrument not work properly, but it will also cause economic losses to users and cause economic disputes. Therefore, the reliability, security and non-volatility of the data must be guaranteed.
The electricity consumption of each user is converted into a pulse quantity proportional to the electricity quantity through a large-scale electric energy metering integrated circuit. The CPU accumulates the power consumption of each user according to the collected pulse amount, stores it in the non-volatile memory, and displays the power consumption of each user in turn by the display circuit. The remote meter reading system directly implements the remote automatic meter reading function in the central control room, and can form a regional meter reading network centered on the central control room. Since the antenna fixed-point communication is used, after the installation height is completed according to the technical requirements, 24h communication can be carried out, and it is not affected by the fluctuation of the power grid. The remote transmission of measurement data is realized through the remote communication interface circuit. Multi-user meter manufacturers welcome you to come to consult and understand.
