Description
Technical field
The utility model belongs to a kind of intelligent electronic electric energy meter that can implement Long-distance Control to it.
Background technology
The Automatic meter reading system of resident's electric energy meter is used widely at present, existing Automatic meter reading system adopts the data acquisition modes of " pulse collection device+pulse electric energy table " more, owing to reasons such as the short circuit of electromagnetic interference (EMI), pulse interface, open circuit, loose contacts, regular meeting makes the shown data of step-by-step counting data that Automatic meter reading system gathers and electric energy meter inconsistent, causes bigger data acquisition error; And this class Automatic meter reading system majority only has " checking meter " function, and no management function can not be implemented effective management to defaulting subscriber, illegal user; The power supply department that has adopts the IC-card ammeter, though can reach automatic charge purpose, but power supply department can't obtain user's electricity consumption situation and equipment running status information, the IC-card ammeter is also so often by artificial destruction, and IC is not suitable for the charging method (being that different time sections adopts different expenses standards) of time-shared charge yet.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can realize carrying out telemanagement and stopping sending electric control it by network service, and has the electronic electric energy meter of time-shared charge function.
The technical scheme that addresses the above problem is: the utility model is provided with the sensing element that is connected with power circuit, it is characterized in that: the electric energy consumption signal output part of sensing element is connected with the electric energy computation chip input end that is provided with mould/number conversion circuit, the electric energy computation chip pulse signal output end connects the single-chip microcomputer input end, described single-chip microcomputer is connected to real time clock circuit, and be provided with operational data shows signal output terminal, connect display by driving circuit; Be provided with the operational data output terminal, be connected with the communication interface circuit that is provided with communication interface; Be provided with the switch controlling signal output terminal, connect feed circuit by ON-OFF control circuit.
Principle of work of the present utility model is: the communication interface of this device is connected with the data communication line of Automatic meter reading system, can carry out exchanges data by network service and Automatic meter reading system: Automatic meter reading system can send command information to the single-chip microcomputer of electric energy meter, also can directly read ammeter data from communication interface.This device sensing element is input to electric energy computation chip with user's electric energy consumption signal and converts pulse signal to, be input to single-chip microcomputer again and count computing, single-chip microcomputer is kept at the counting operational data in the machine on the one hand and reads for Automatic meter reading system, be converted into shows signal output on the one hand, show power consumption by the driving circuit driving display, when Automatic meter reading system when this address electric energy meter sends read signal, single-chip microcomputer is promptly counted operation result to the power consumption in the memory and is input to Automatic meter reading system by communication interface and data line; Kilowatt meter reading-out system can be in advance stores user's the electrical information (prepayment electric expense) of purchasing in the single-chip microcomputer into, when user's power consumption surpasses permissible value, single-chip microcomputer promptly sends control signal, by the power supply of ON-OFF control circuit cut-out to the user, because single-chip microcomputer is connected to real time clock circuit, so the electricity price of the different rates that can download according to Automatic meter reading system and the time of reading, realize time-shared charge from real time clock circuit.When electric energy meter or communication line broke down, kilowatt meter reading-out system can not get back-signalling, promptly can obtain the information of device fails immediately, implemented electric energy meter is managed automatically.
The utility model is integrated in one ic for energy metering, single chip circuit, display device, communication interface circuit, form intelligentized electronic electric energy meter, make it have the function that to carry out exchanges data by network service and Automatic meter reading system, and electric energy meter itself can be finished the counting calculating process to power consumption, the data that its display data presented and Automatic meter reading system read all are to be calculated by the single-chip microcomputer that is provided with in the electric energy meter to finish, and have guaranteed that electric energy meter video data and Automatic meter reading system read the consistance of information; The utlity model has the function of time-shared charge, and can make Automatic meter reading system that it is realized telemanagement and stops sending electric control.
