The utility model is compared with existing various electric energy meters; Have following technique effect: 1, the utility model is applied to the CPU card technique of present information in the electric energy meter, has waterproof, characteristics such as antimagnetic, and observing and controlling is accurate; Security and reliability are high, and having realized pays the fees earlier afterwards uses; 2, adopted mixing charging prepayment meter, a kind of rational foundation is provided user's electric energy metrical; 3, multiple functional; Embody user's remaining sum and the used amount of money and electric weight in time; Show used electric weight of active user's this month simultaneously; And can pass through the current executed electricity price that the button page turning shows ladder electricity price, tou power price, user in the electric energy meter, and the preceding user's of plug-in card last time information such as remaining sum.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the main program flow chart of the utility model.
Embodiment
As shown in Figure 1; A kind of electronic type is mixed the charging prepayment meter; Comprise microprocessor, microprocessor is connected with clock circuit with a CPU card respectively, thereby this microprocessor also is connected according to charge information with a control relay circuit and opens or closes subscriber's line circuit.Thereby wherein microprocessor also is connected with the ESAM module safety check is provided, microprocessor also is connected with the carrier communication interface with infrared, RS485 respectively.
Like Fig. 1, shown in 2, the utility model is realized through following technical scheme: the hybrid charging prepayment intelligent of electronic type electric energy meter, this electric energy meter mainly comprises ic for energy metering, funtion part circuit.The funtion part circuit comprises electronic microprocessor, LCD display, clock circuit, CPU card, control relay circuit, button, infrared, RS485, carrier communication circuit etc.Wherein, Electronic microprocessor is the core of this electric energy meter; Improve the energy with power circuit, the electric energy of gathering metering module through microprocessor calculates, and ESAM module, LCD display, clock circuit, CPU card, control relay circuit etc. all are connected as shown in Figure 1 with microprocessor.
Its principle of work is described below:
The user handles to Utilities Electric Co. and opens an account, and gets the CPU card after paying the fees, and inserts ammeter; Electric energy meter is to the capable safety identification authentication of sticking into of user; After authentication is passed through, again electric energy meter is carried out parameter update and supplements with money, after the electric energy meter successful recharging; The automatic connecting subscribers participating circuit of electric energy meter, and the prompting user can normally use.The electric energy meter Automatic Cycle shows information such as remaining sum, total electricity consumption, each rate power consumption and current electricity price.And the information such as historical electric weight, time on date, tariff period that can show electric energy meter through the button page turning.
Electric energy meter calculates through the clock in showing; Which rate electricity price user's electric energy meter this moment is in; Calculate user power utilization simultaneously at which ladder, electric energy meter will according to corresponding ladder electricity price and rate electricity price with carry out the amount of money in user's electric energy meter is reduced, if remaining sum is during less than the warning amount of money 1 set; The form that electric energy meter is used up reminds the user to purchase as early as possible; If remaining sum is during less than the warning amount of money 2 set, electric energy meter cuts off user power utilization automatically and reminds the user, but at this moment user's plug-in card recovers electricity consumption.When remaining sum was zero, electric energy meter cut off user's electricity consumption once more automatically.The utlity model has certain function of buying on dredit, when Utilities Electric Co. opens the function of buying on dredit in the table, set necessarily when buying the amount of money on dredit, can the overdraw power consumption of certain amount of money of electric energy meter is being bought the amount of money on dredit not then, and electric energy meter can not cut off user's electricity consumption.After the user goes power supply department to purchase electricity once more, insert in the electric energy meter, electric energy meter will be eaten up part of the amount of money of overdraw part automatically.
Mix billing function: just be meant that electric energy meter has ladder and charges and two kinds of functions of time-shared charge, electric energy meter can pass through the parameter setting, changes the charging way of electric energy meter.Electric energy meter can be set to have only the ladder billing function, also can be set to have only the time-shared charge function, or both has both simultaneously.
The time-shared charge function just is meant in one day and carries out according to different period rates, the corresponding unit electricity price of each rate; The unit electricity price remains unchanged in segmentation, but can change according to the rate electricity price that the different periods is provided with.Designed in the utility model 2 when cover segment table, segment table when having for 8 day in the segment table during every cover can divide in the segment table period 14 day during each day, can establish 4 rates, and have two cover rate electricity rate table, shown in figure (2).The electric weight that the resident uses in the different time section, performed electricity price is different.The pairing electricity price of each rate, when rate changed, electricity price was also along with variation.
The ladder charging is meant and in the electricity consumption billing cycle of an agreement, is divided into two sections or multistage to power consumption, the corresponding unit electricity price of each segmentation; The unit electricity price remains unchanged in segmentation, but can change with segmentation is different.Designed 6 gradients in the utility model, gradient can be provided with arbitrarily.
| Ladder 1 electricity price | Ladder 3 power threshold | Ladder 4 electricity prices | |
| Ladder 1 power threshold | Ladder 2 electricity prices | Ladder 4 power threshold | Ladder 5 electricity prices |
| Ladder 2 power threshold | Ladder 3 electricity prices | Ladder 5 power threshold | Ladder 6 electricity prices |
The electric weight and the electricity charge that are collected according to the staged total rate of electricity; The implication that not only meets electricity price; And reflected that comparatively intactly electric power supplies the characteristics of usefulness; Solved the problem that existing unitary system electricity price exists preferably, also had laid a good foundation simultaneously for further carrying out demand Side Management work.
The hybrid charging intelligent electric energy meter of the utility model adopts the amount of money as measurement unit; Adopt the high precision microprocessor to calculate, accurately can reach behind the decimal 8, The data the EEPROM protection of high reliability; Has infrared, RS485 and carrier communication interface simultaneously; Be convenient to centralized automatic meter-reading and telemanagement, be provided with high precision clock in the table, can freeze the electric quantity data of every month.
