Abstract
The utility model discloses a watt-hour meter which comprises a current sampling unit, a voltage sampling unit, a metering unit, a MCU micro control unit and LCD display units. The input ends of the current sampling unit and the voltage sampling unit are electrically connected with a power supply; the output ends of the current sampling unit and the voltage sampling unit are electrically connected with the input end of the metering unit; the output end of the metering unit is connected with the input end of the MCU micro control unit electrically; the input ends of the LCD display units are connected with the output end of the MCU micro control unit electrically; two LCD display units are arranged, one is arranged on the watt-hour meter, and the other is arranged in the home of the user. The watt-hour meter has the advantages that the watt-hour meter can not only be convenient for the user to observe the power consumption and to find whether the watt-hour meter has errors or not to avoid unnecessary loss, but also reduce the work load of the electric power department.
Description
Technical field:
The utility model relates to a kind of electric energy measuring equipment, specifically is a kind of single-phase electronic energy meter.
Background technology:
At present, the electric energy meter of family expenses generally all is to install concentratedly in certain outdoor electric energy metering box, therefore, the general user has only the power consumption of just knowing last month or preceding quarter when the electricity consumption bill is sent it to house, and at ordinary times the user if wonder the words of power consumption, then need to check on the outdoor electric energy meter or the decorrelation power department inquiry of making a phone call, this not only makes the user to become unusual trouble of checking of power consumption, and make electric energy meter show to make mistakes or measure when running into electric energy meter infringement to stagger the time, can cause some unnecessary loss because the user can't in time find; In addition, a large amount of inquiry phone workload of department that also can increase electric power.
The utility model content:
The technical problems to be solved in the utility model is, a kind of user's Direct observation power consumption that not only can make things convenient for is provided, and finds in time whether electric energy meter mistake takes place, thereby avoids unnecessary loss, but also can reduce the electric energy meter of power department workload.
Technical solution of the present utility model is that a kind of electric energy meter with following structure is provided: it comprises current sampling unit, voltage sampling unit, metering units, MCU micro-control unit and LCD display unit; The input end of described current sampling unit and voltage sampling unit is electrically connected with power supply; The output terminal of described current sampling unit and voltage sampling unit is electrically connected with the input end of metering units; The output terminal of described metering units is electrically connected with the input end of MCU micro-control unit; The input end of described LCD display unit is electrically connected with the output terminal of MCU micro-control unit; Described LCD display unit has two, and one of them LCD display unit is arranged on the electric energy meter, and another LCD demonstration is installed in the user family.
After adopting above structure, compared with prior art, the utlity model has following advantage: the utility model is owing to be provided with two LCD display units, and one of them LCD display unit is installed in the user family, therefore, the utility model not only can make things convenient for user's Direct observation power consumption, finds in time whether electric energy meter mistake takes place, thereby avoid unnecessary loss, but also the workload that can significantly reduce power department because of not needing to phone power department inquiry power consumption.
As a kind of improvement of the present utility model, described LCD display unit is installed in and is meant in the user family that the LCD display unit can be arranged on the clock and watch in the user family.The LCD display unit is arranged on the clock and watch in the user family both can have avoided the utility model additionally to take space indoor in the user family, can not influence in the user family indoor attractive in appearance again.
Description of drawings:
Accompanying drawing is the principle of work block scheme of the utility model electric energy meter.
Specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in drawings, in this specific embodiment, the utility model electric energy meter comprises current sampling unit, voltage sampling unit, metering units, MCU micro-control unit and two LCD display units; The input end of described current sampling unit and voltage sampling unit is electrically connected with power supply; The output terminal of described current sampling unit and voltage sampling unit is electrically connected with the input end of metering units; The output terminal of described metering units is electrically connected with the input end of MCU micro-control unit; The input end of described two LCD display units all is electrically connected with the output terminal of MCU micro-control unit, and one of them LCD display unit is arranged on the electric energy meter, another LCD display unit is set directly on the clock and watch in the user family, in other words, the LCD display unit is fixed on the moment display panel of the transparent bell jar of clock and watch the inside, and is electrically connected by the output terminal of the MCU micro-control unit in lead and the outdoor electric energy meter.In this specific embodiment, also be electrically connected with infrared interface unit, RS484 interface unit, key-press input unit, pulse output unit and storer on the output terminal of MCU micro-control unit; Described power supply is electrically connected with Power Management Unit; The output terminal of described power supply pipe-line cell keeps the battery and the battery of checking meter to be electrically connected with data.
In this specific embodiment, described current sampling unit, voltage sampling unit, metering units, MCU micro-control unit, LCD display unit, infrared interface unit, RS484 interface unit, key-press input unit, pulse output unit, storer and Power Management Unit are circuit unit conventional in the prior art, so do not give unnecessary details at this.
