Definition and related knowledge of multi-user smart meter manufacturers : Multi-user energy meter is a meter used to measure electric energy. It can detect 36 households (single-phase), 12 households (three-phase), and any combination of single-phase and three-phase households below 36 households. Such a simple combination is bulky, unattractive and uneconomical.It is necessary to design a centralized, multi-user, all-electric energy meter with small size, complete functions and economy.This centralized table can be used in the same unit or even a building, but it is not a simple combination of multiple single tables. Multi-user all-electric energy meters are also called cluster meters, which are in line with China's national conditions. Most of the residential buildings or apartments in China are mainly residential buildings.A building generally contains several units, and the number of each unit is generally close to ten, dozens, and dozens more.In view of the above, in order to facilitate meter reading and power management, some property management departments have installed multiple single-block meters in the stairwell.Such a simple combination is bulky, unattractive and uneconomical.It is necessary to design a centralized, multi-user, all-electric energy meter with small size, complete functions and economy.Multi-user smart meter manufacturers believe that one unit of this centralized meter or even one building can be used together, but it is not a simple combination of multiple single meters. It is worth mentioning that multi-user smart meter manufacturers have another type of cluster meter on the market, whose sampling is performed separately for each household, but the electricity consumption calculation of each household is completed by the same chip or single-chip microcomputer system.This type of table does not have the function of "one household, one table", both in terms of structure and principle.Another problem is that the calculation of the energy consumption of each household is completed by the same component, that is, the calculation of the electricity consumption of each household has to wait in a queue.This will inevitably cause errors in electricity measurement. The larger the number of households, the greater the error.
