Abstract
The utility model relates to an electric energy meter display device which comprises a carrier wave communication module, a single-chip microcomputer, a display screen, a button, a power source, a buzzer, a memory, a plug and an outer case; a carrier signal on a power supply wire is demodulated and filtered into an effective digital signal by the carrier communication module and then is then sent to the singlechip for processing; if the signal is prepayment information or real-time energy consumption information, the single-chip microcomputer calculates the data and judges whether a user needs to pay the electricity bills; the processed data is stored in the memory and then sent to the display screen; if the signal is the power-off information, power-off time is directly sent to the display screen; and when reminding a user to pay the electricity bills or of the power-off time, the display screen displays a warning mark and the buzzer gives out an alarm. In the utility model, the carrier wave communication technology is introduced to realize that the consumed electrical quantity and the power-off time can be reviewed without changing the current installation mode of a carrier wave electric energy meter, therefore, the electric energy meter display device can not only provide convenience for users, but also automatically remind users to pay the electricity bills instead of the power supply department and bring benefits to the power supply department in providing value-added services.
Description
Technical field
The utility model relates to a kind of electric energy meter display, especially introduces the indoor display that carrier communication shows outdoor electric energy meter information about power and section, place power failure information.
Background technology
Along with the widespread use of power-line carrier communication, the carrier electric energy meter installation constantly increases.In China, electric energy meter mostly is installed in the open air, this brings the inconvenience of three aspects to the user: first, inconvenient user understands the prepayment information and the instant power information of electric energy meter, when the user adopts the prepayment mode electricity payment, only when purchasing electricity or monthly closing entry, just know own prepayment information, and the user only checks and is installed in behind the outdoor electric energy meter the just instant power information of understanding oneself; Second, inconvenient user predicts power failure information, because China's electric energy meter is installed to such an extent that relatively disperse, when the section power equipment need overhaul and when having a power failure, power supply department in time issues power off notifying often can not for the user, so that do not carry out the user's appearance inconvenience in life that has a power failure and prepare; The 3rd, inconvenient power supply department is pressed for payment of electricity charge work, because the user can not in time know the dump energy of oneself, power supply department just need urge subscriber payment to supplement with money by the working method of making a phone call or directly calling when the forward purchasing electric weight is about to use up, this traditional mode of pressing for payment of wastes time and energy, and also can cause the contradiction between user and the power supply department sometimes.
Summary of the invention
For solving the weak point in the background technology, the utility model provides a kind of indoor display, it is corresponding with user's outdoor carrier electric energy meter, can not only provide convenience for prepayment information and instant power information that the user understands electric energy meter, but also the power failure information that can in time issue power supply department reminds the user to carry out the preparation that has a power failure, and replaces power supply department to press for payment of the electricity charge automatically.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model is made of carrier communication module, single-chip microcomputer, display screen, button, power supply, hummer, storer, plug, nine parts of shell; The carrier communication module connects single-chip microcomputer as the carrier signal transmission channels, single-chip microcomputer is as information processing core, it connects storer and is used for long preservation parameter and data, it connects display screen and is used for video data to the user, it connects button and selects displaying contents and the up-to-date power consumption of copy reading for the user, it connects, and hummer user reminding user purchases electricity or the early warning user has a power failure, plug connects with power supply so that qualified voltage to be provided, and shell then organically is combined together to form protection with other seven parts.The carrier communication module is filtered into effective digital signal with the carrier signal demodulation on the line of electric force, and single-chip microcomputer is handled the significant figure signal that transmits.If digital signal transfers is prepayment information and instant power information, single-chip microcomputer can calculate and judges whether the user needs to pay the fees data, information about power or fee payment early warning is shown send to display screen then, deposits data message in storer simultaneously; If digital signal transfers is power failure information, single-chip microcomputer is then directly sent to power off time display screen and is shown.If single-chip microcomputer recognizes digital signal that the user need pay the fees or transmit when being power failure information when carrying out data processing, the hummer of its control all can be made early warning.
The beneficial effects of the utility model are, it is introduced carrier communication and provide a kind of indoor display under the situation that does not change existing carrier electric energy meter mounting means, can not only provide convenience for prepayment information and instant power information that the user understands electric energy meter, but also the power failure information that can in time issue power supply department reminds the user to carry out the preparation that has a power failure, and replace the power supply department automatically prompting user in time to pay the fees, reduced the contradiction between user and power supply department, helping power supply department provides later on and is similar to the value-added service that issues power failure information.
