Users will purchase information such as electric amount of money, price of electricity to transmit to the electric energy meter through user's card, the electric energy meter reduces the amount of money, the automatic stop power supply of electric energy meter after the amount of money is used up in real time according to user's power consumption and price of electricity.
The price of electricity type can be presumed as two kinds single price of electricity and price of electricity of the ladder. The price of electricity of the ladder means that sets up the power consumption per family as several ladders and segments or divides the grade to price and calculate the expenses. The ladder type mechanism of price of electricity can inhibit the electric wasting phenomenon effectively, lead residents to economize on the electricity, use the electricity rationally, direction of the ones that are reformed with the electricity by the residents in the future.
Main technological characteristic
The liquid crystal Chinese character character of the large screen reveals, it is lighted while inserting the card, infrared communication automatically that it is in a poor light and have
Eight digital display Remaining sum, total power consumption reveal the range can reach 999999.99kwh
The price of electricity is tall in precision The range can be up to 99.999999 yuan / degree
Warning amount of money, warning way of two grades can be set up at will. The warning way is sound to only call the police, operate a switch and call the police. Table inner buzzer give out, call the police when the sound takes place to only call the police, and in a poor light to glimmer. The electric energy meter stops the power supply to operate a switch while calling the police. These two kinds of alarm can cancel calling the police through inserting user's card while happening.
Overload cuts out when user's average power exceeds the presuming value, the automatic stop power supply of electric energy meter. The ammeter is electric automatically after waiting for for 5 minutes.
The encrypting is strong to use and encrypt the card and encrypt algorithms dynamically, the system data will not be deciphered.
The magnetism keeps the relay adopting the magnetism of high-power and keeping the relay, low power dissipation, dependability is high.
Infrared communication Help users check meter, presume the ammeter parameter
Dispose the high-accuracy clock
Settle account and reach automatically and freeze and record the total power consumption in the present moon automatically on account day in the moon, his zero clearing. Begin the new price of electricity of ladder and charge and circulate. Can presume freely on account day
Can record the power consumption for recent 2 months automatically
Can record from the total power consumption from users open an account
Have two kinds of prices of electricity of price of electricity of single price of electricity, ladder types, can set up the card to switch over at any time through user's card, price of electricity
The price of electricity can be divided into four ladders at most The electric consumption of each ladder, price of electricity can set up the card to change at any time through user's card, price of electricity
485 can realize the real-time long-range function of checking meter, controlling user's power consuming state etc. to network the communication.
Overvoltage protection cuts off user's power when the circuit is too high in voltage, in order to protect users to use the electric apparatus.
Note: Take The need of the mark is customized
