Take following scheme according to above problem the utility model that needs to solve:

A kind of intelligent power utilization management devices is provided, comprises shell, place wiring board in the shell and display screen, electric power incoming line terminal, power outlet terminal, voice button, function button and the loudspeaker that is exposed to case surface and is connected with internal circuit board corresponding function circuit; Described wiring board is provided with power circuit, single chip circuit and the storer that is connected with single chip circuit, clock circuit, metering circuit, display driver circuit, temperature sensing circuit, draw/contacting controling circuit, indicator light circuit and sound circuit.

The utility model concrete function is as follows:

1. have the electric energy metrical function, can calculate energy datas such as power consumption, voltage, electric current, power;

2. have electricity charge scaling function: the electricity charge that calculate every month automatically according to the electricity price of setting and power consumption, and when the charge calculation day of next month arrived, the electricity charge auto zero of last month, ammeter restarted to calculate the electricity charge of the current moon;

3. has telecommunications functions: can adopt RS485, carrier wave or micropower wireless mode;

4. has the infrared communication function;

5. have the external keyboard interface, can extended keyboard, the user can utilize keyboard to carry out the parameter setting;

6. has Presentation Function: data such as display voltage, electric current, power, table sign indicating number, temperature, date, time, electricity price, the electricity charge;

7. can parameter or data query be set by touch screen operation;

8. have memory function, can store a plurality of months electric weight and corresponding electricity charge data;

9. have the audio alert function: can set warning content, when some Event triggered, loudspeaker send corresponding audio alert information automatically;

10. have voice broadcast function: by allow ammeter report of that month current power consumption and corresponding electricity charge information by the voice button above the lower casing, this function makes things convenient for the elderly or caliginous people to use;

Have electric weight control function: can set the power consumption limit of ammeter every month or every day, when the approaching setting of power consumption limit, by the loudspeaker alarm, when power consumption transfinited volume, ammeter was operated a switch automatically;

Function of temperature control: because there is temperature sensing circuit this device inside, can measure room temperature, detect limit value so can install design temperature to each, when room temperature during near the temperature limit set, by the loudspeaker alarm, device is operated a switch automatically when indoor temperature is lower than this limit value, device ability automatic closing when room temperature rises to satisfactory temperature, this function can control roller office's air-conditioning temperature, prevent that air-conditioner temperature from setting too low waste electric power.

By this intelligent power utilization management devices, the home-confined every data that just can recognize oneself electricity consumption easily and intuitively of user are convenient to user's planned supply and use of electric power, form economy consciousness.And the management method of science can be provided for enterprises and institutions' using electricity wisely, existing relatively electric energy meter has cost advantage when the utlity model has functionality advantage, and simple for structure, be convenient to maintenance maintenance.
