Description
Technical field
The utility model relates to a kind of electric energy meter, relates in particular to a kind of electric electric energy meter that prestores.
Background technology
The electronic electric energy meter of present common use all needs to check meter, meter reading method mainly contains the meter reading methods such as 485 communications, infrared communication and carrier communication, although these meter reading methods have shortened the consuming time of manual metering widely, but be subject to kilowatt meter recorder and the environment of checking meter, inefficiency, equipment goes wrong and also will go to scene to keep in repair simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is: existing structure is subject to kilowatt meter recorder and the environment of checking meter, inefficiency, and equipment goes wrong and also will go to scene to keep in repair simultaneously, and a kind of electric electric energy meter that prestores is provided.
In order to overcome the defect that exists in background technology, the technical scheme that its technical matters that solves the utility model adopts is: this electric electric energy meter that prestores comprises CPU, serial port level chance-over circuit, IC-card read write line, warning circuit and radio-frequency card, described CPU connects serial port level chance-over circuit, CPU connects warning circuit, connect the IC-card read write line on serial port level chance-over circuit, the IC-card read write line connects radio-frequency card.
The beneficial effects of the utility model are: it is simple in structure for this electric electric energy meter that prestores, and be easy to realize, and technology is simple, ripe, and reliability is high.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, comprise CPU, serial port level chance-over circuit, IC-card read write line, warning circuit and radio-frequency card, described CPU connects serial port level chance-over circuit, CPU connects warning circuit, connect the IC-card read write line on serial port level chance-over circuit, the IC-card read write line connects radio-frequency card.
