Further, wherein real-time timepiece chip adopts DALLAS DS1302 or EPSONRX8025.
The utility model is applied to the IC-card technology of present information in the electric energy meter, has waterproof, characteristics such as antimagnetic, and observing and controlling is accurate, security and reliability height, having realized pays the fees earlier afterwards uses, and has possessed the progressive pricing billing function, can promote electric energy saving effectively.Ladder electricity price electric energy meter of the present 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 communication 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.
Description of drawings
Accompanying drawing 1 is a logic theory block diagram of the present utility model;
Accompanying drawing 2 is the control flow chart of ladder valuation in the utility model.
Embodiment
Come the utility model is described in further detail below in conjunction with accompanying drawing:
Purpose of design of the present utility model is in view of the electrified progress of the trend of China's electricity price reform and China, according to the intension of electricity price, characteristics, the requirement of demand Side Management and low pressure resident's the electricity consumption present situation that electric power supply is used, problem at existing metering electric energy meter and the existence of unitary system electricity price, research and develop a kind of novel electronic formula ladder electricity price prepayment meter, utilize the ladder electricity price that is provided with in the electric energy meter, the user was made the different electricity price of the different execution of power consumption number at every month.
As shown in Figure 1, the utility model mainly comprises ic for energy metering, funtion part circuit.The funtion part circuit comprises electronic microprocessor, LCD display, clock circuit, IC-card interface, relay control, button, infrared, 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 by microprocessor calculates, and circuit such as IC-card, CD display, clock circuit, IC-card interface, relay control all are connected as shown in Figure 1 with microprocessor.
Principle of work of the present utility model is as follows:
The user handles to Utilities Electric Co. and opens an account, and gets IC-card after paying the fees, and inserts ammeter, and electric energy meter is provided with and supplements with money.The inner connecting subscribers participating circuit automatically of electric energy meter, and hummer prompting after successful recharging, the prompting user can normally use.Electric energy meter from driving wheel show remaining sum, total electricity consumption, always with information such as the amount of money.And can show information such as the current electricity price of electric energy meter and time on date by the button page turning.Electric energy meter calculates by the clock in showing, user's power consumption of this month at this moment is in that ladder, electric energy meter will carry out the amount of money in user's electric energy meter is reduced according to corresponding ladder electricity price, if remaining sum is during less than the warning amount of money set, the electric energy meter automatically prompting user goes to purchase as early as possible.When remaining sum is zero, electric energy meter will cut off user's electricity consumption automatically.
The utility model also can be designed to have certain function of buying on dredit, when Utilities Electric Co. opens the function of buying on dredit in the table, set certain when buying the amount of money on dredit, can the overdraw power consumption of certain amount of money of electric energy meter, buying the amount of money on dredit not then, 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.
Ladder electricity price function of the present utility model:
So-called progressive pricing, generally, " be exactly that electricity is used manyly more, the money of friendship is also many more.Otherwise electricity is used manyly more, and electricity price is also just few more.", to realizing,, realize which type of electricity price just can be provided with arbitrarily by the unit price of each ladder electric weight is adjusted with ladder electricity price two aspects.
Designed 8 ladders in the utility model, 8 ladders can be provided with arbitrarily.
| Ladder 1 power threshold | Ladder 1 electricity price | Ladder 5 power threshold | Ladder 5 electricity prices |
| Ladder 2 power threshold | Ladder 2 electricity prices | Ladder 6 power threshold | Ladder 6 electricity prices |
| Ladder 3 power threshold | Ladder 3 electricity prices | Ladder 7 power threshold | Ladder 7 electricity prices |
| Ladder 4 power threshold | Ladder 4 electricity prices | Ladder 8 power threshold | Ladder 8 electricity prices |
Be meant the low pressure resident according to the maximum electric weight that the user consumed, its gradient amount classification is set collects the corresponding electricity charge according to above-mentioned.Can be provided with eight ladder electric weight threshold values in the table at most, and the corresponding electricity price of each ladder electric weight threshold values.The user in every month the difference of power consumption, ammeter will be reduced the corresponding electricity charge automatically, when user's power consumption during less than ladder 1 electric weight threshold values, ammeter is reduced the amount of money according to period electricity price 1, when power consumption greater than ladder 1 electric weight threshold values, and during less than ladder 2 electric weight threshold values, ammeter can carry out remaining sum according to period electricity price 2 automatically and reduce.Analogize successively, reduce according to the ladder period electricity price that is provided with.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.
Certainly, concrete ladder electricity price need be by the unified decision of power department, and the utility model has only provided a possible example.
