Abstract
The present invention relates to a power line carier intelligent IC card electric energy metering system with function of resisting illegal use of electric energy. Said system is formed from main meter,submeters and general power line. It uses the power line carrier transmission technology to completely solve the problem of illegal use of electric energy between main meter and submeters. Its main technique is characterized by using power line carrier information transmission technology to implement electric energy metering management, and checking the sum of submeter meterings against the main meter metering to judge whether the electric energy is illegally used or not. It can be extensivel yused in various situations having need of making management for resisting illegal use of electric energy and IC card pre-payment meter application.
Description
The present invention relates to a kind ofly realize that by the power line carrier modulation-demodulation technique anti-electricity-theft and IC-card concentrates the electric energy metered system of charge.
At present, known IC-card watt-hour meter concentrates Fare Collection System to realize the concentrated toll administration of electric energy, but does not have the possibility of anti-stealing electricity function or anti-electricity-theft completely ability and this kind of widespread use electronic electric meter.Like this, just limited the performance of the potential of the application of IC-card watt-hour meter and electronic electric meter, made stealing become one of power department heavy losses.On the other hand, with maturing of power line carrier modulation-demodulation technique and commercialization, make this technology of application carry out electric energy management and become a reality.
The objective of the invention is to utilize the power line carrier wave information transmission technology to realize the management of electric energy metrical,, thereby realized anti-electricity-theft ability up hill and dale, also make the charge of IC-card electric energy become practicality, reliable technique with this by checking of summary table and submeter electric energy metrical.
The object of the present invention is achieved like this: total system is made up of summary table, submeter and line of electric force.Line of electric force is ordinary power line, comes electric energy transmitting with it, also transmits carrier information with it.Like this,, check the power consumption on the line of electric force, when summary table variable and each sub-metering value sum are within allowed band, think no stealing by the information transmission of summary table and submeter; When difference exceeded permissible value between the two, thinking had stealing, and the summary table powered-down is stopped power supply.Like this, just can prevent any type of electricity filching behavior.
Describe the principle of work of system in detail below in conjunction with concrete system design.
Summary table adds single machine unit, modulator-demod, control module, trap unit composition based on the three-phase electronic electric meter.Each Elementary Function is: single machine unit be used for the collection and treatment display message and control units corresponding; Modulator-demod be used for digital signal with single-chip microcomputer be modulated on the line of electric force and the demodulation line of electric force on carrier signal and be transferred to single-chip microcomputer; Control module is used for controlling respectively switching on and off of three-phase electricity; The trap unit is used for stoping the outside propagation of carrier signal, prevents the phase mutual interference between identical systems, and a plurality of these systems are moved simultaneously becomes possibility.
Submeter adds single machine unit, modulator-demod, control module, trap unit composition based on single-phase electronic electric meter.Each Elementary Function is: single machine unit be used for the collection and treatment display message and control units corresponding; Modulator-demod be used for digital signal with single-chip microcomputer be modulated on the line of electric force and the demodulation line of electric force on carrier signal and be transferred to single-chip microcomputer; Control module is used for controlling switching on and off of electricity; The trap unit is used for stoping carrier signal to propagate to the user, prevents the interference of carrier signal to other electrical equipment.
System does not have specific (special) requirements with line of electric force, uses the line of electric force that uses at present to get final product.System comes transferring electric power and carrier information with line of electric force.
The work of system divides summary table and submeter two parts.
The work of submeter is: be responsible for reading the information about power of user's purchase and deposit single-chip microcomputer inside in from IC-card, reduce the electric weight that the user buys according to the information of metering circuit, simultaneously the power consumption and the existing electric weight of explicit user on LCDs; When the existing electric weight of user reached certain value, submeter provided warning message, and the prompting user buys; When the existing electric weight of user was 0, then the start-up control unit disconnected supply line; In addition, the single-chip microcomputer of submeter is also by modulator-demodular unit and summary table transinformation.
The work of summary table is: single machine unit carries out the information transmission with submeter by modulator-demodular unit.At first, when first dress, search all by the sequence detection address code and hang over submeter below this summary table, find out the address of each submeter, system enters normal operating conditions afterwards.Summary table is collected once all submeters at regular intervals during this time every interior information about power, calculate every electric weight of going up all submeters mutually and, and with summary table this charge value of measuring is mutually compared, think no stealing in the time of in error range, thinking when greater than this scope has stealing to take place, and summary table start-up control unit disconnects this phase, at interval behind the certain hour, connect this phase supply line again, and begin new testing process.
Like this system fundamentally prevented various from the submeter stealing may, utilize the electricity bill control of IC-card again, make this system become a kind of practicality, efficiently, fundamentally stop the electric energy metered system of stealing from the submeter.
