Multi-user meter manufacturers remind you of several factors that you must consider when choosing a multi-user meter:
1.Flexible installation methods: layered installation or cabinet installation, layered installation ** can manage 36 rooms (single output) or 18 rooms (dual output); cabinet installation ** can manage 240 Rooms.
2, with real-time power display function, real-time display of the user's power load.
3. It has the function of timing power off and on: It can set the time period (maximum 8) divided in one day and the on-off status of each user's relay in different time periods through instructions to realize the user's timing on-off control.
4, with the user's dual-loop power supply function: the 2 outlets of the meter are provided to a user for use, except for the total calculation of the 2-wire power consumption, the function of each power supply line of the user is exactly the same as that of the selected meter type, The parameters can be set separately to achieve independent control.
Multi-user meter manufacturers describe the scientific description of multi-user smart meter data storage technology:
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. Remote transmission of measurement data through remote communication interface circuits (such as RS485, CAN bus).
Multi-user electricity meter manufacturers have the flexibility to use the meter. There are some programmable parameters, such as meter number, number of metered households, communication rate, meter pulse constant, time value of multi-rate period, power supply status of each household, etc. The measured data is the electricity 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.
