Description
Technical field
The utility model relates to technical field of electric power, particularly relates to a kind of expense control intelligent electric energy meter and to deduct fees functional reliability verifying attachment.
Background technology
The large scale application of expense control intelligent electric energy meter saves human cost greatly.Expense control intelligent electric energy meter has the function of automatically carrying out power-off according to power consumer paying situation, powering on.In actual motion, find that part expense control intelligent electric energy meter cuts off the fault of user's power supply automatically when appearing at the non-arrearage of user.This type of fault Producing reason is analyzed as follows.
Taking control intelligent electric energy meter uses the energy storage of electrochemical capacitor for ESAM module for power supply when power-off, use Clock battery is powered for MCU.When electric energy meter detects power-off, MCU sends instruction and performs to ESAM module operation of deducting fees.When ESAM module is deducted fees successfully, result of deducting fees returns to MCU.If the energy storage of electrochemical capacitor is just in now exhausting, then result of deducting fees cannot be returned to MCU by ESAM module, and MCU then thinks that ESAM module is deducted fees unsuccessful.After electric energy meter powers on again, MCU will send fee deduction instruction again to ESAM module, causes repeating to deduct fees to the amount of money in ESAM module, makes the remaining sum in ESAM module be less than E
2, namely there is " amount of money bears saltus step " phenomenon in the remaining sum in PROM module.If the remaining sum after repeating to deduct fees in ESAM module is lower than E
2the overdraw thresholding amount of money of PROM, then namely MCU sends power-off signal, the automatic trip of control overhead switch, cuts off the power supply of user.
Easily there is above-mentioned " amount of money bears saltus step " phenomenon in expense control intelligent electric energy meter, causes unnecessary economic loss to power consumer when frequent power-off.Above-mentioned this electrical energy meter fault is caused by the design defect of software often, can be corrected by software upgrading.But the project reliability of deducting fees of electric energy meter not detected in the conventional test project at present before electric energy meter is networked, also not relevant test method and testing equipment.Cannot determine before networking whether electric energy meter, after running, " amount of money bears saltus step " phenomenon can occur, the electric energy meter can only recalling this batch after fault occurs is unified carries out software upgrading.This not only adds the operation cost of power grid enterprises, also brings economic loss to a certain degree to power consumer, and causes bad social influence.
Summary of the invention
To deduct fees the reliability of function to solve survey fees control intelligent electric energy meter in prior art, bring the problem of economic loss to power consumer after avoiding problematic electric energy meter to network, the utility model provides a kind of expense control intelligent electric energy meter to deduct fees functional reliability verifying attachment, the practical operation situation of this verifying attachment simulation electric energy meter, electric energy meter is powered on, power-off is tested, to find the expense control intelligent electric energy meter that there is " amount of money bears saltus step " problem, and concentratedly before this batch of electric energy meter networks carry out software upgrading, economic loss is caused to user after avoiding electric energy meter to network.
The utility model solves the technical scheme that its technical matters adopts:
Expense control intelligent electric energy meter is deducted fees functional reliability verifying attachment, comprise: power module, control module, display module, keyboard, driver module, adjustable voltage module and adjustable current module, controller is electrically connected with power supply, display, keyboard and driver module respectively, driver module is connected with adjustable current module with adjustable voltage module simultaneously, adjustable voltage module and adjustable current module receive voltage, the current input terminal of electric energy meter respectively, regulate the voltage of pressure regulator to export and electric current output according to the parameter of electric energy meter.
Described power module is connected with controller, adjustable voltage module, adjustable current module, for it provides 220V working power; Controller module is connected with driver module, keyboard and display module, input through keyboard electric current, the parameter such as voltage, time, voltage exports as 0V to 380V continuously adjustabe, electric current exports and is 0A to 100A continuously adjustabe to the maximum, this parameter is transferred to voltage, current output module by driver module, and voltage module and current module are input to the voltage and current loop of intelligent electric energy meter relevant parameter, parameters value is displayed over the display simultaneously.
The beneficial effect that the utility model has is: the utility model to its certificate authenticity of deducting fees before expense control intelligent electric energy meter networks, can be concentrated this batch of electric energy meter that there is " amount of money bears saltus step " problem and carry out software upgrading.Greatly reduce the operating cost of power grid enterprises, and ensure the normal electricity consumption of user, avoid the bad social influence causing economic loss to user and bring thus.
Accompanying drawing explanation
Fig. 1 is that expense control intelligent electric energy meter is deducted fees the circuit theory diagrams of functional reliability demo plant.
