Mechatronics energy meter (half-electron formula electric energy meter), electronic power meter, Multi-purpose electronic formula electric energy meter, prepayment are power-consuming
The development and production of energy table, multi-rate meter, maximum demand meter, loss electric energy meter etc., these semi-intelligent formulas electricity after 2000
Energy table is widely used in the aspects such as household electricity, commercial power.
2009, first ammeter with network communicating function that British government will research and produce first was applied to family
After in electricity consumption, China national power network proposes the concept of " intelligent electric meter " at home immediately：26 nets of State Grid Corporation of China subordinate are saved
Company, when the second half year in 2009, concentration has formulated unified technical standard, and being at this moment just in State Grid Corporation of China will
Build up under the overall situation of intelligent grid, therefore the electric energy meter to be purchased from now on is collectively referred to as intelligent electric meter, it is main at that time
Or to solve the problems, such as step price and remote meter reading, certainly also have some functions will when later expansion.In fact, intelligence
The function that ammeter possesses has embodied on original Semi-intelligent Modular formula electric energy meter, be nothing but national grid again give ammeter
The function of network service and photoelectric communication is mixed, is sent out in the form of professional standard.
And existing ammeter when program is upgraded, it is necessary to dismount watchcase, it is time-consuming and take energy.
