Abstract
The utility model discloses a novel electric energy metering device, comprising a micro control unit which is connected with a metering unit, a display device, a relay control unit, and a power supply unit. The micro control unit is also connected with a wireless communication module and an alarm device. The metering unit is connected with a voltage transformer. The display device is a liquid crystal display. The micro control unit is a single-chip microcomputer or DSP controller. By employing the novel electric energy metering device, the work load of work personnel is greatly reduced, and errors are not easy to occur during the meter reading. The novel electric energy metering device has a simple structure.
Description
Technical field
The utility model relates to a kind of new electric energy measuring apparatus.
Background technology
Electric energy meter is for measuring the instrument of electric energy, existing electric energy meter normally staff goes to check meter, the staff's who increases workload, and manual metering can be easy to occur mistake, although and the measuring apparatus of some automatic data loggings also arranged in existing electric energy meter, but existing apparatus structure is all very complicated, and cost is very high.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of new electric energy measuring apparatus is provided, and it has advantages of automatic data logging, simple in structure.
To achieve these goals, the utility model adopts following technical scheme:
A kind of new electric energy measuring apparatus, it comprises micro-control unit, micro-control unit is connected with metering units, display device, relay control unit, power supply unit respectively; Micro-control unit also is connected with wireless communication module, alarm; Described metering units is connected with voltage transformer (VT).
Described display device is liquid crystal display.
Described micro-control unit is single-chip microcomputer or dsp controller.
Principle of work of the present utility model: metering units gathers electric energy by voltage transformer (VT) and is uploaded to micro-control unit, micro-control unit shows by display device the electric energy that metering units gathers, if voltage transformer (VT) increases suddenly at a certain period power consumption, likely the people arranged in power stealing or can leak electricity somewhere, micro-control unit is controlled alarm equipment alarm, micro-control unit is uploaded to host computer by wireless communication module by used electric energy, not be used in the people for checking meter.
The beneficial effects of the utility model: use the utility model, greatly reduce staff's workload, and be not easy to occur mistake when checking meter, simple in structure.
The accompanying drawing explanation
Fig. 1 is system construction drawing of the present utility model.
Wherein, 1. micro-control unit, 2. wireless communication module, 3. metering units, 4. relay control unit, 5. alarm, 6. power supply unit, 7. voltage transformer (VT), 8. display device.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Fig. 1, a kind of new electric energy measuring apparatus, it comprises micro-control unit 1, micro-control unit 1 is connected with metering units 3, display device 8, relay control unit 4, power supply unit 6 respectively; Micro-control unit also is connected with wireless communication module, alarm; Described metering units 3 is connected with voltage transformer (VT) 7.
Described display device 8 is liquid crystal display.
Described micro-control unit 1 is single-chip microcomputer or dsp controller.
Principle of work of the present utility model: metering units 3 gathers electric energy by voltage transformer (VT) 7 and is uploaded to micro-control unit 1, micro-control unit 1 shows by display device 8 electric energy that metering units 3 gathers, if voltage transformer (VT) 7 increases suddenly at a certain period power consumption, likely the people arranged in power stealing or can leak electricity somewhere, 1 control alarm of micro-control unit 5 is reported to the police, micro-control unit 1 is uploaded to host computer by wireless communication module 2 by used electric energy, not be used in the people for checking meter.
Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
