We all need electricity in our daily lives, so the meter that measures electricity must be indispensable for us, so today we will talk about the output part of the electronic energy meter .

The output port of the electric energy meter mainly includes the public display and external communication, control interface, and so on. The public display shows the account number and power of each household in turn and can work continuously for 24 hours, and users can check their consumption at any time. It is not difficult to see that the above-mentioned centralized multi-user electric energy meter is a high-tech product that combines electronic technology, computer technology, and communication technology. It has a small size and can accommodate a large number of households (the area of ​​a 24 centralized multi-user electric energy meter is about 1/3 of the simple centralized installation of a single meter), and it also has the function of "one household, one meter". It is worth mentioning that there is currently another type of centralized multi-user electronic energy meter on the market. The sampling is carried out separately for each household, but the calculation of electricity consumption for each household is done by the same chip or single-chip microcomputer system. . This type of watch does not have the function of "one household, one watch" in terms of structure or principle. Another problem is that the calculation of the electricity consumption of each household is done by the same component, that is, the calculation of the electricity consumption of each household has to wait in line and cycle. This will inevitably cause errors in electricity metering. The more households, the greater the error.

Many electric energy meters are the same, but their functions are slightly different. The same is true for single phase meter .
