Abstract
The utility model discloses a split type IC card electric energy meter, which comprises a metering unit and a display operation unit. The split type IC card electric energy meter is characterized in that the metering unit and the display operation unit are separated from each other. The display unit is arranged inside the house of a user. The display unit is an indoor display operation unit equipped with a single-chip microprocessor, an IC card interface and a display screen. The metering unit is equipped with a current loop communication interface. The metering unit communicates with the display unit and provides power for the display unit at the same time through a current loop communication bus. Due to the adoption of the split type IC card electric energy meter, a user is able to perform the operations such as data inquiring, electricity purchasing and the like at home only through the indoor display unit.
Description
Technical field
The utility model relates to split type IC-card electric energy meter.
Background technology
What adopt in the market is the electric energy meter that integrates information demonstration, electric energy metrical, IC-card data processing.Now residential building generally is installed on centralized management in the unified panel box (or switchgear building) with electric energy meter, and electric energy meter is more, the user is purchased electricity etc. cause certain inconvenience.And, also be prone to the stealing problem.This electric energy meter partly separates metering section and display operation, and the user only to indoor display device operation, promptly can realize the whole operation to the electric energy meter part.And indoor display device only shows as one and the port of input, does not purchase functions such as electricity, metering and directly do not handle, and is installed on the user within doors, can be user-friendly.
The utility model content
The purpose of the utility model is to provide a kind of can make the user directly not contact under the situation of ammeter main body, through oneself indoor display device electric energy meter is operated, and purchases a kind of split type IC-card electric energy meter of electricity, data query etc.
The split type IC-card electric energy meter of the utility model; Comprise metering units and display operation unit; It is characterized in that said metering units and display operation unit separately, display unit is installed in the users home, and said display unit is the indoor display operation unit of a band chip microprocessor, IC-card interface and display screen; Said metering units contains an electric current loop communication interface, and metering units is communicated by letter with indoor display unit through the electric current loop communication bus and is indoor display unit power supply simultaneously.
Said electric current loop communication bus adopts two core twisted-pair feeders, is connected to indoor display unit by the electric current loop communication interface of metering units, is the chip microprocessor power supply and the communication with it of indoor display unit.Said display unit also has newspaper device, and it is by the chip microprocessor control of indoor display unit.
In fact the utility model has formed a WT-MSR and an indoor display operating device because metering units and display operation are partly separated, and the user only to indoor display unit operation, promptly can realize the whole operation to the electric energy meter part.Indoor display unit is not directly handled and is purchased functions such as electricity, metering only as a port that shows and import, and indoor display unit is installed on the user within doors, and the user just can accomplish operations such as purchasing electricity, data query at home, is very easy to the user.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of metering units.
Fig. 3 is the structural representation of indoor display unit.
Embodiment
As can beappreciated from fig. 1, the split type IC-card electric energy meter of the utility model metering units is formed with the indoor display unit of band IC-card interface, and metering units is linked on the indoor display unit by two core twisted-pair feeders, to its power supply, and communicates with it.
As can beappreciated from fig. 2 metering units is except having chip microprocessor, metering section, load control, communications portion, main control part, clock etc.; Also has the electric current loop communication interface; Therefore it is except being responsible for metering, managing purchasing electricity, agreement etc.; Also indoor display unit is supplied power, and communicate by letter with indoor display unit through the electric current loop communication bus.The road electric current loop communication interface that metering units provides, in fact metering units is as the main frame of electric current loop communication.
As can beappreciated from fig. 3 indoor display unit has chip microprocessor, IC-card interface, acoustic alarm, LCD display, electric current loop communication interface and communicates by letter with chip microprocessor through the electric current loop communication bus; The ammeter information that receives metering units shows; Supply the user to insert IC-card simultaneously; The user only can be accomplished at home through indoor display unit it is investigated inquiry in full, purchase electric and so on operation.
Claims (3)
1. split type IC-card electric energy meter; Comprise metering units and display unit; It is characterized in that said metering units and display unit separate, display unit is installed in the users home, and said display unit is the indoor display unit of a band chip microprocessor, IC-card interface and display screen; Said metering units contains an electric current loop communication interface, and metering units is communicated by letter with display unit through the electric current loop communication bus and is the display unit power supply simultaneously.
2. according to the said split type IC-card electric energy meter of claim 1; It is characterized in that said electric current loop communication bus adopts two core twisted-pair feeders; Electric current loop communication interface by metering units is connected to indoor display unit, is the chip microprocessor power supply and the communication with it of indoor display unit.
