The electric energy meter box comprises an electric energy meter, which is characterized in that a detection device for detecting operation exception of the electric energy meter is provided, wherein an input signal interface of an input signal processing unit of the device is connected with a pulse output terminal of the electric energy meter or an RS485 communication output terminal, the output signal interface of the input signal processing unit is connected with a data input interface of a singlechip, an output signal interface of the singlechip is connected with the output signal processing unit, an output interface of the output signal processing unit is connected with an alarm unit, and the singlechip is connected with a display unit and a push button. The device of the utility model can discover fault of the electric energy meter in operation in time, reduces huge electric loss caused by damage of the electric energy meter, greatly decreases electric dispute between the electric supply department and the users, and having great economic benefits and social benefits.
Description
Technical field
The utility model belongs to power supply or distribution technique field.Be specifically related to a kind of electric energy metering box.
Background technology
The electric energy meter of power supply department management at present spreads all over the various places, town and country, basically reach one of each household, tens0000 at least in each district, hundreds of thousands only at most, power department realized reading the ammeter directly, charging the family, serve the family, each power supply station on average manages the counting cost by gas meter work of more than 10,000 user's electric energy meter, ten thousand electric energy meters of the management 2-3 of the power supply station that has.Electric energy meter energising work in 24 hours, the normal power supply that non-metering fault does not influence the user takes place in most electric energy meters, but directly influence the accuracy of electric energy metrical, particularly at the thunderstorm season in summer, electronic electric energy meter is easy to because thunderbolt causes superpotential to damage.If the electric energy meter of certain electricity consumer broke down after just checking meter several days, generally be when checking meter next time, could find (after two months); The much electricity table breaks down and is not easy to find when check meter for the first time in the back, has been nearly four months time when checking meter again.Nearly four months electricity consumption of electricity consumer will not have any foundation and will remedy electric weight, and power supply department produces dispute with electricity consumer often, has both reduced electricity charge recovery, has influenced social reputation again.The power consumption of electricity consumer is increasing year by year now, electrical appliance every month the power consumption in family how is more than 1000KWH, electric energy meter calculates by 1% failure rate, and nearly 1,000,000 electric quantity loss can be lost in every month in each district, and the electric quantity loss quantity that causes owing to the fault of electric energy meter is very considerable.So, press for a kind of ammeter box of invention now with electric energy meter operation exception measuring ability.
The utility model content
In order to overcome the drawback of prior art, the utility model provides a kind of electric energy metering box of automatic detection electric energy meter operation exception, and it can detect the electric energy meter operation conditions, in time finds the fault of electric energy meter in service.
This practicality solves the technical scheme that its technical matters adopted: the electric energy metering box that designs a kind of automatic detection electric energy meter operation exception, comprise electric energy meter, it is characterized in that being provided with an electric energy meter operation exception pick-up unit, the input signal interface of the input signal processing unit of this device connects the pulse output end mouth or the RS485 communication output port of electric energy meter, the output signal interface of input signal processing unit connects the Data Input Interface of single-chip microcomputer, single-chip microcomputer output signal interface connects the output signal processing unit, the output interface of output signal processing unit connects alarm unit, and single-chip microcomputer connects display unit and button.
Display unit connects the LED demonstration in the utility model; Alarm unit is hummer or LED light emitting diode or the two combination; Single-chip microcomputer connects the RS485 communication interface simultaneously.
The beneficial effect that the utility model had is: the fault that can in time find electric energy meter in service, reduce owing to electric energy meter damages the huge electric quantity loss that causes, significantly reduce the electric weight dispute of power supply department and electricity consumer, have very big economic benefit and social benefit.

Fig. 1 is the utility model functional-block diagram;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Electronic electric energy meter all has a signal output port, according to the size of electricity consumer power load, and the output pulse signal that does not stop.The utility model is monitored this pulse signal in real time, and signal is carried out analysis and judgement, the indication of then reporting to the police during abnormal signal.The pulse output signals of electric energy meter is exported to the input signal processing unit by electric energy meter PORT COM RS485, passes to single-chip microcomputer after the conversion of input signal processing unit and carries out acquisition process.Size according to the electricity consumer load sets in advance timing, such as 24 hours in Single Chip Microcomputer (SCM) program.If in the time of setting, this electric energy meter signal output port does not have pulse signal output, and single-chip microcomputer does not collect input signal, and then single-chip microcomputer record date and time at that time deposits the single-chip microcomputer storer in; Simultaneously single-chip microcomputer sends output signal, through corresponding equipment action in the corresponding alarm unit of output signal processing unit output control signal control (the LED lamp is glittering, hummer sound warning).Press button, can inquire about this electric energy meter work unusual date and time takes place, can show fault-time and the date and the fault numbering of fault electric energy meter on the display screen simultaneously.
The utility model can detect 12 road electric energy meters simultaneously, the input of an electric energy meter does not have signal in setting-up time, single-chip microcomputer does not detect signal, then judge the table fault No. one, the single-chip microcomputer output signal is through a pilot lamp, the hummer action of output signal processing unit control alarm unit correspondence.Indicate the table fault No. one.The then a plurality of panalarm actions of multichannel fault.
Single-chip microcomputer expansion RS485 communication interface in the utility model is connected with remote control center, realizes strange land detection electric energy meter state.
Above scheme can utilize other patterns to realize, reaches effect on-the-spot and the strange land detection such as wireless remote control etc.
The above all belongs to the utility model protection domain.
