Description

Technical field

The invention relates to an electrical energy storage meter based on a new principle, and in particular to a method of storing values, by which the server of the electricity supplier or the power distributor transmits through a network modem and stores the value in a memory module ( SVM) or in an IC card and up to an electric meter with prepayment and direct payment, without accounting required.

BACKGROUND OF THE INVENTION

A traditional watt hour meter for measuring the amount of electricity consumed per hour for a specified period by a controller is used in all electricity consuming institutions, such as houses, offices and public buildings. This first generation of electricity meters is becoming a very complex and expensive way of reporting because the controller has to visit the places where electrical energy meters are installed in households and businesses and check the difference between the amount of energy consumed from the previous measurement and the amount of energy used. power consumption at the time of measurement, ie. the amount of power consumed per month or period.

The calculated delivery and the result of the consumption are processed by the supplier and an invoice is printed, which is sent to the consumer after a preliminary calculation process including data entry and calculation of the consumed quantity, the consumer completes the payment application and makes the payment, processing the application. The account is sent once more to process outstanding debts and defaults. When fraudsters appear as controllers (collectors) and when metering costs make up a large part of the cost of electricity delivered due to the increased personal cost of the controller, the remote electric energy meter deserves attention as a new 5 measurement method and is now widely is used. The remote electric power meter makes it possible to reduce the individual costs of the controller. The amount so consumed each month can be processed by computer, the bill can be sent and debts can be recalculated. In particular, the management of a remote electric energy meter applicable to gas meters and water meters requiring additional energy and communication networks, such as telephone networks or radio networks, is being avoided by the supplier and the consumer, as this leads to an increase in the cost resulting from the joint operation of gas20 meters and water meters, the server of the remote measurement center and the installation and operation of the communication equipment according to additional communication functions related to remote measurement. For these 25 reasons, a third-generation electric energy meter with a third-generation payment card that does not require visual metering can be taken into account. An electric meter with a payment card IC30 can solve the problems of first- and second-generation electric meters in several aspects. However, the efficiency of an electric energy meter with an IC payment card 35 depends on how the payment and calculation of the value of the information in the IC card is performed. In particular, when the power supply is interrupted completely due to the limit of the IC card being exhausted, 40 may become an unexpected accident.

Examples of carrying out the invention

The method for transmitting and storing values according to a preferred embodiment of the invention, as well as the structure and operation of the electric energy storage meter without the need to visually capture the measured readings using the meter, are described below in more detail.

The invention can be applied in a wattmeter, gas meter, hydrometer and calorimeter using payment and prepayment calculation methods combined with electronic payment collection method. The invention is limited to wattmeters for clarity. Also, in all communication processes for transmitting and storing values according to the invention, a basic coding algorithm for triple DES coding is applied.

The connection between the master server and the wattmeter terminal is as follows. First, the task of creating an access key (Ks) is solved in the server and in the terminal. The coding algorithm for triple DES coding is applied via the access key. Further, when it is necessary to solve the task of creating a character, MASS SHS using triple DES encoding is used. When values are stored in the wattmeter terminal, values such as the calculated modulated table of electrical power used, unit cost and time are corrected and stored. When the values are read from the wattmeter terminal, the credit balance, day, month and year values used to specify the calculated modulated table of electrical power used, unit price, and timer readings are analyzed and information is obtained for abnormal use.

First, before describing the method for transmitting and storing values according to the invention, examples of character generation and the coding algorithm thereof are described with reference to FIG. 4.

After solving the task of creating an access key (Ks) in the server and in the terminal through a connection between the server and the stored electrical energy meter, the triple DES encoding algorithm is triggered by the access key (Ks). MAC SHS using triple DES encoding can be used to solve the symbol generation task. Further, the symbol generation and coding algorithm are described in more detail with reference to FIG. 4.

For character generation, the magnitude of the original data is multiplied into 64 bit information using the fill in step 1. These are D1, ... and Dn in Fig. 4. In step 2, the data values (Dn) of the bit information are F-encoded using the triple DES encoding according to the input key (K).

The character values are 01, ..... and On in step 3. At the same time, the values obtained from the collected value data (Dn) with the recorded value (Op-1), except for the first recorded value 01, are F-coded. For coding, the magnitude of the original data is multiplied into 64 bit information using the fill in step 1. These are D1, .... and Dn.

In step 2, the triple DES encoding algorithm is applied to the F-coding. The coded messages are O1 + On in step 3.

The master key (CN) of the master terminal, the internal secret key for access (Ks) used in communication processes, has a value of 128 bits. The internal terminal key (CT) is generated by the master key (CN) of the master terminal, the access key (Ks) is generated through the terminal internal key (CT) The master key of the main terminal (CN) and the internal key of the term (CT) are selected from different ranks.

The Terminal Internal Key (CT) is generated by encoding the terminal ID from the triple DES encoding algorithm using the master key (CT) of the master terminal. The internal key is stored in the terminal in a generated step and is generated in the main terminal in the first step of the connection. Namely, CT = Encrypt (ID, KH).

The access key (Ks) is generated by encoding an R generated random data in the master terminal by a triple DES encoding algorithm using the terminal's internal key (CT), which makes the connection. All encodings are made using the access key (Kis) during the communication process. Namely, Ks-Encrypt (R, KT). In the invention, the algorithms of (1) the value storage command, the (2) differentially modified modulating control command based on hours, days, months or seasons, and (3) the command used for days, weeks, or months, and timer reading information (control for abnormal use is added) are taken additionally. They are described using FIGS. 1-3. First, they are described with reference to FIGS. 1 the nature of the stored values and command.

Step 10: The master terminal generates a first random database (RI, R2, and n) and sends the first random database to the terminal. The access key is generated by the key generation algorithm using an internal secret key of the terminal (CT [n]). Namely, Ks is Encrypt (RI, CT [η]). For comparison, when identifying a terminal, the first character value Slh = Sig (R2, Ks,) is generated by the symbol generation algorithm. The terminal receives the first random data (RI, R2 and n) and generates the access key as generated in the master terminal using the terminal's internal secret key (CT [n]). Namely, Ks = Encrypt (R1, KT [η ]).

Step 12: The terminal generates a second character value Sit - Sig (R2, Ks) through the symbol generation algorithm, generates a second random variable R3 by sending Sit and R3 to the main terminal.

Step 14: The master terminal can identify the terminal by comparing Sih to Sit. When the terminal is identified, the master terminal generates a third character value S2h = Sig (H + R3 + EnAmnt, Ks) and sends S2h to the terminal with the coded total monetary information (EnAmnt). Thus, the "H" is a jump in the representation of a memorable command value. The terminal generates a fourth character value S2t «Sig (H + R3 + En Amnt, Ks) and identifies the main terminal by comparing S2h with S2t.

Step 16: When the master terminal is identified, the terminal increases the value, encodes Balance + ID as M-Encrypt (Balance + ID, Ks) and sends the encoded value M to the master terminal. The master terminal identifies the terminal once again by decoding the M Cat Balance '+ ID' - Decrypt (M, Ks) encoded value and comparing the ID 'with the ID. When the terminal is identified, the balance is recorded in a recording file.

The differential charge flow of the modulated control command based on hours, days, months and seasons (boot system) is presented with reference to FIG.

Step 20: The master terminal generates the first random data (RI, R2 and n) and sends it to the terminal. The access key is generated by the key generation algorithm using the secret key (CT [n]). Namely, Ks · = Encrypt (Rl, KT [n]). For comparison, when identifying a terminal, the first character value Slh-Sig (R2, Ks) is generated by the symbol generation algorithm. The terminal receives the first random data (R1, R2, and η) and generates an access key each time the master terminal uses the terminal's internal secret key (CT [n]). Namely, Ks-Encrypt (Rl, KT [nj. Namely, Ks-Encrypt (Rl, KT [n]).

Step 22: The terminal generates the second character Slt-Sig (R2, Ks) through the symbol generation algorithm, generates the second random data (R3) and sends Sit and R3 to the main terminal.

Step 24: The master terminal can identify the terminal by comparing Sih with Sit. When the terminal is identified, the master terminal generates the third character value S2h ~ Sig (H + R3 + Mode + Unit, Ks) and sends the third character value to the terminal along with the modulated information and power unit (charge) value information. The terminal generates a fourth character value S2t = * Sig (Η + R3 + Mode + Unit, Ks) and identifies the main terminal by comparing S2h with S2t.

Step 26: When the master terminal is identified, the terminal converts the boot system, encodes Balance + ID as M »Encrypt (Balance + ID, Ks) and sends the encoded value M to the master terminal. The master terminal identifies the terminal once more by decoding the coded value M as Balance '+ Decrypt (M, Ks) and comparing ID' with ID. When the terminal is identified, the balance is stored in a recording file. Finally, the flow of the checking command of the information for use by days, weeks or months and by a timer (use for controlling abnormal consumption) is described in detail with reference to FIG.

Step 30: The master terminal generates the first random data (RI, R2 and n) and sends this data to the terminal. The access key is generated by the key generation algorithm using the terminal's internal secret key (CT [n]). Namely, Ks “Encrypt (Rl, KT [n]). The first character value Sih - Sig (R2, Ks) is generated by the symbol generation algorithm for comparison when identifying the terminal.

The terminal receives the first random data (RI, R2, and n) and generates the access key, as done in the master terminal, using the terminal's internal secret key (CT [n]). Namely, Ks = Encrypt (Rl, KT [n]).

Step 32: The terminal generates the second character value Stl 'Sig (R2, Ks) through the value generation algorithm, generates the second random data (R3) and sends Sit and R3 to the main terminal.

Step 34: The master terminal can identify the terminal by comparing Sih to Sit. When the terminal is identified, the master terminal generates the third character value S2h = Sig (Η + R3 + Time, Ks) sends this value to the terminal along with Time. The terminal generates the fourth character value S2t = Sig (Η + R3 + Time, Ks) and identifies the main terminal by comparing S2h with S2t.

Step 36: When the main terminal is identified, the terminal encodes an information file (Info), including using details (Log), differentially loaded modulated table (Mode TV), time counter (Timer), balance (Balance), and ID.

Namely, the terminal encodes Info via M = Encrypt (Info, Ks) and sends the encoded value M to the main terminal. Thus Info '= Log + ModeTB + Blance + ID. The master terminal identifies the terminal again by decoding the coded value M of Info '= Decrypt (M, Ks) and comparing ID' with ID. When the terminal is identified, the information consumed in days, weeks or months and the detected information is returned to the recording file and checked. The transmission values and the coding algorithm applicable to the invention are described above.

Its application in a real electrical energy meter is discussed below.

The maximum number of electrical energy storage meters that can be connected to a single pole transformer is limited to 256 units. In a transformer for converting 3.3 KV to 220 V supply voltage, one local LSU serves 250 storage electric energy meters.

The service and monitoring units (LSs) with different serial numbers are connected to the second side of different transformers. An ASSU connects up to a maximum of 256 Lss, which can control 65536 electrical energy storage meters. When managing 256 Lss, a single server in the structural tree can manage 16,000,000 AS areas. Thus, given the performance and performance of the server, it is preferable to limit the maximum number of stored electrical energy meters managed by the local server. A tri-byte ID is defined as the main network modem of the user and as a modem of an electrical energy meter (micom) in the case where the signal passes through the transformer to the other side 220V. Micom, which has a function to encode a bus, a secure encryption algorithm and a coding key, protect against theft or can selectively use a secret access module (SAM), which is an IC card of the type of subscriber identification module (SIM). The power meter, the character tank, and the display can be operated using an additional microcontroller. This verifies that the control of the LCD and the calculation of the consumed electrical power make it difficult when the energy meter transmits data and is connected to the main terminal.

It is also recognized that the transmission of time information to the energy meter is time limited. Namely, when it is assumed that the transfer of information to one family requires Is, then within 1 hour the transfer of information to 3, 600 families. The real-time clock is loaded and the differential charging is applied according to time. The clock is adjusted and controlled all the time. The abnormal use of electrical power is constantly monitored and digital encryption (protection) is used in cases where the diversion or leakage occurs through the connection of the network modem to the PC.

Digital protection is implemented systematically by combining software and hardware. Digital protection for controlling the abnormal use of electrical power is implemented by a method in which the terminal transmits details of the amount of electrical power used per unit time, over a period of hours, days, weeks or years to the server as 2.44 kilobytes of information. The server records the information in a database, compares the recorded information with the information coming in the next moment, and compares the result of the comparison with the total amount of consumed electrical power for the same period. When voltage is applied to an external terminal at a time when the power supply is interrupted by a relay, the theft of electricity is limited. Accordingly, information about critical moments is transmitted to the server.

All details of the power consumption can be used as a basis for a contract for renegotiation of output prices by using a stored ratio of purchased electricity based on an approximate estimate of the consumed electric power for days, months or seasons and on the basis of of the total amount of electricity consumed over hours, days, months or seasons.

When the mains switch interrupts the supply of electrical power due to the exhaustion of the stored credit amount, in the case of electric shock, in special cases, or in the use of electrical power by switching on the load before the meter, abnormal use of electrical power is detected by a verification method. the presence of a load of voltage.

The loan amount is transmitted and stored in the wattmeter, gas meter, water meter and calorimeter via the network modem. The amount of the credit for the electric power is saved in the SVM, and the residual value is stored in the respective zones of the electronic cash register of the IC card.

The structure and operation of the electric energy storage meter are described in more detail with reference to FIGS. 1-7.

Figure 5 shows an electrical energy meter that transmits and stores valuable information through an electrical network modem. In Fig. 5, the rising relay 1 is of the type of a switching relay interrupter for interrupting the supply of electrical power. Shunt resistor 2 measures AC (AC) by a manganese (Mn) resistance of 0.1 t.

When interlock relay 1 is interrupted, the power consumption sensor 3 reports normal power consumption if the sensor output signal is “0” and the Is and 21 terminals have bypassed the circuit; the sensor recognizes that electrical power is consumed illegally when the sensor output signal is “1”. Audio frequency generator 4 requires a new symbol for the amount of credit to the SVM, once the balance in the symbol exchanger 10 has been consumed, generating an audio signal, and thus directs the transmission and storage of the credit amount by the consumer of electrical power. Chalk Size / Value Added IC Card 5 registers the serial number of the managed database database memory card (CSN) through the power distributor master key by managing the credit amount of the electric energy meter according to the invention and verifying the presence of a legally registered SCN on the IC card when the server wants to transmit the loan amount, thus preventing electricity theft.

Voltage divider 6 adjusts 117, 220 and 240 V AC to be within the voltage range of an analog-to-digital voltage converter (V-ADC) 7. Voltage limits are selected by selecting the ratio of values of two resistors connected in series. The V-ADC 7 is a circuit for converting an alternating voltage analog signal into a 16 bit digital signal. An analog-to-digital current converter (I-ADC) 8 is a circuit for converting an alternating current signal through the shunt resistor 2 into a 16 or 20 bit digital signal. Power Consumption Operational Circuit 9 calculates electrical power (Watt) by multiplying the digital signal of V-ADC 7 by the digital signal of I-ADC 8 and converting the multiplied result into a pulse and a broadband signal. The operating circuit of the consumed electrical power 9 compares the phase of voltage with the phase of current, calculates the angular difference between the two phases, whereby the output as a signal produces a phase difference, which is applied to charge things that temporarily use inductive load. of symbols 10 reduces the symbols according to the amount (Watt / hour) of electrical power consumed per unit of time, requires new symbols from the decimal bank of symbols when the symbols in the exchanger 10 are consumed, and reduces the new ones symbols according to the amount of power consumed.

If a decimal character bank is exhausted, hundreds of characters are required to be written to the SVM and the decimal decimal is filled in again. The required symbols for the SVM 166 can be received by the SAM 164. ID process. The RTC and Power Consumption Table 11 perform the differentiation of multiple values of electrical power according to the electrical power supplied and the required state in 50, 75, 100, 150 and 220%. based on a real time interval containing year, month, day, hour, minute and second (YYMMDDHHMMSS).

An IC 78 card reader and recorder opening to ISO 7816 is a communication channel comprising eight terminals defined by ISO 7816, Part 2, containing Vcc, Cik, DIO, RESET, Gnd to synchronize and desynchronize the connection to the IC card. Multi-purpose credit sizes, such as electricity, gas, water, hot water, heat, and a TV installment, are recorded on the IC card by placing the legally issued IC card in the energy meter in the offline / non-autonomous mode.

After recording on the IC card the values transmitted from the gas service server via the value transmitter and the stored electrical energy meter, the IC card is removed, placed in the gas meter and the value information transmitted to the gas meter, and thus reduced the value information on the card according to the amount of gas used. Accordingly, the value transmitter and the electric energy storage meter can operate offline.

Network model 13 transmits data through the electrical network. Each modem is included between 256 network address modem IDs (PLMIDs). The AC / DC voltage source supplies the desired operating voltage through the electrical energy storage meter according to the invention. The tri-byte ID, which is the internal number of the electrical energy storage meter, is written to the ROM during operation. A power independent memory containing instantaneous memory records the state of electric power consumption over a period of time, ie. details of electricity consumption over a period of time, ie the power consumption details for 24 hours are found by recording the amount of power consumed in the energy storage meter as 16 bit information every six seconds, the details of electricity consumption per week by adding seven full amounts of daily power consumption together, and the details of monthly power consumption - by adding the three full quantities of daily power consumption to all others; remotely controls theft of electrical power or abnormal power consumption and makes electronic sales. Encoding block 16, comprising Central Programming Unit (CPU) block 162, secret access module (SAM) 164 to form a coding key and a coding algorithm for storing the loan amount, and a storage unit (SVM) 166 for storing the size of credit, protects against tampering with and use of credit amount information as well as leakage of information and unauthorized decryption. The LCD 17 presents the balance of the credit amount, transmission status, real-time power consumption situation, and collected power consumption information so that it is visually distinguishable by the user. A network input and output terminal 18 consists of Is, 2s, 21, 11 for interconnecting the input and output lines of the electrical network, and a housing preventing physical breakdown. Fuse 19 is a circuit for lightning protection or impulse voltage.

A specific embodiment of a specific type of energy storage energy meter is described above. However, the electrical meter according to the invention can measure at least two types of electrical power by switching on the voltage divider 6, V-ADC 7,1-ADC 8, the blocking relay 1, and the shunt resistor 2 according to the type of electrical power. Namely, when the voltage divider, V-ADC, -ADC, the blocking relay, and the shunt resistor are combined so that at least two types of different voltage sources can be selected or used simultaneously, the corresponding amounts of current will be further measured and processed.

The operation of the electrical energy storage meter having the above structure is described as follows.

As specified by the electricity supplier or distributor, the amount of credit from the main terminal is stored in SVM166 at another terminal via the network modem 13, using the method of storing the amount of credit, each electric energy meter calculates load according to the quantities consumed operational power triggered by the operational circuit Consumed electrical power 9, comparing the calculated load with the balance of credit amount information stored in SVM 166 and calculating the load in h token exchanger 10.

When the balance is not more than the permitted amount in SVM 166, the user is informed of the balance status by an audible signal from the audio frequency generator. When the balance is insufficient, the credit value is transformed from the main terminal to SVM 166 by the specified method for storing the loan amount or the power supply is excluded from the blocking relay 1. The loan amount information can be stored in S VM 166 through the connection between the master terminal a terminal and a terminal in an electrical energy storage meter according to the invention. However, it is possible to transmit the power value information stored in the IC card 5 to the SVM and to store the power, gas, water and calorie information transmitted to the SVM from the inserted IC card for a family or institution where a legally allocated amount of money is recorded in the electrical energy storage meter according to the invention.

The electrical energy storage meter according to the invention reflects on the LCD 17 display such information as the monthly consumption and the balance of the card installed therein by using a certain amount of electrical power in the range recorded in the SVM and signals through the audio frequency generator 4 when the balance is no more than what is specified on the map. Accordingly, the user requests a credit transfer server to the server. The credit amount is automatically loaded from the bank account, previously opened, or settled through a credit card. The electrical power value is transmitted in a non-autonomous mode through the network and stored in SVM 166.

The value is reduced according to the power scale used.

Accordingly, the electricity supplier and distributor can save costs by omitting the meter reading process, entering and calculating the amount used, and printing and sending bills. The electricity bill is paid in advance. Accordingly, the process related to payment delays is omitted. It is also possible to reduce the electricity bill due by prepayment, the application of a differential payment according to the time that the electricity was used, and the costs to be saved by the difference between the purchase and the sale price of the electric power. The electricity provider can manage the high values additional to the business.

So, in order to avoid the use of fake cards other than the IC card legally issued by the supplier or distributor of electrical power, the SAM 164 for card identification is loaded into the memory electrical energy meter. When the card is inserted into the terminal, the terminal and the card are mutually identified. When the amount of monetary information on the card is transmitted from the terminal as a credit amount, the terminal operates according to the coding process shown in FIG. Accordingly, the use of a fake card is avoided. A method of deleting a coding key that damages the terminal and damages the meter may be considered against the background of decryption and leakage of information, such as the destruction of the energy storage meter in the case of terminal or card fraud.

Thus, the coding algorithm and the coding key in the terminal create only a key to reduce the amount in which credit amount information is reduced in accordance with the amount of power consumed. Accordingly, it is not possible to increase the amount of money or credit information. In particular, in the invention, when the user / subscriber contacts the ARS server by telephone or digital extension telephone to request a transfer of the loan amount, the amount used is selectively determined by using the credit card or bank account. The value transfer process begins as soon as the payment is guaranteed. The process can also be done online. In particular, an automatic transfer of the loan amount is possible when it is stored in the framework of the automatic transfer agreement between the seller and the distributor of the electricity and the financial institution, and is reduced according to a specific table and for people who have never used computer or information communications network. In particular, in the case of trade in payment claims through the SET e-commerce process with a direct payment card, the server operating as a commercial website on the Internet may create digital protection (DE) of the commercial details, which has the effect of a password for commercial details. In this way, the trade process cannot be corrupted or falsified.

The implementation of the method and conditions of the invention are described in more detail.

1. Method of generating, transmitting and storing the amount of credit.

Credit amount information is generated through the link operating with the symbol management database, using the master key (MK) of the supplier or distributor of electrical power. The symbol ID number required by the network LAN modem is dialed through the Area Service and Monitoring Unit (AS) and Local Service and Monitoring Unit (LS). When the request for the ID number and connection symbol is completed, the legality of the server and the terminal is determined by the specified method of identification. The information transmitted on the amount of credit through the network is stored in the storage module (SVM).

2. Method of transfer and storage of additional value.

The efficiency of the invention is enhanced by an additional value transfer function that can be used in connection with a wattmeter, gas meter, water meter, calorimeter and hot water heat meter operating autonomously with the IC card without selecting the communication line. The generation and transfer of added value is performed by the specified method for generating and transmitting values. The extra value is stored in the IC card instead of in the energy meter. The additional information about the gas, water, hot water and heat values stored in the IC card can be used by placing the standalone IC card in the meter and in the water meter that are compatible with the IC card described in the Korean Application Forms. patent 98-6947 and 98-6948 to the same applicant. Therefore, management efficiency is maximized.

3. Consumption of credit amount information.

The amount of credit saved in SVM is reduced in the symbol exchanger (TE) 10 according to the amount of power consumed. Symbols are reduced per unit time by the respective miles. When the symbol corresponding to the minimum unit is exhausted, the credit amount information is reduced by the new sign request method.

4. Differential application of power consumption percentages.

The method of using electric power, through which it is possible to differentiate differently the consumption of electric power, uses the percentages by dividing the reporting periods into weekdays and weekends, seasons and months, during which the amount of usable credit from the program is automatically selected.

In the modulated Table 11 of consumed electrical power, different percentages can be applied differentially by using a real-time clock (RTC) according to the separation of reporting periods and the characteristics of delivery and consumption of electrical power, as well as its use, for example 100% for daily rate during weekdays, reduction of 75% of the tariff before and after working hours during weekdays, reduction of 50% for night rate, additional surcharge of 200% during working hours, and additional surcharge of 300% from 2 to 4 after noon in the summer when the use of air conditioners increases sharply.

Because the separating TE 10 is applied in proportion to the use of a certain amount of electrical power, the stored loan amount is applied differentially. Accordingly, the power consumption is optimized over each time period. Thus, delivery efficiency and power consumption are optimized. Accordingly, electricity bills are reduced.

5. Balance check and automatic shutdown.

Credit information for the SVM 166 is presented on the LCD so that the user can check the balance at any time. When the loan amount is spent, the symbol exchanger informs the user by an audible signal that the last symbol has already been used up. When the credit amount is not updated before the last symbol is used up, the power source is switched off by sending a cut-off signal to a blocking relay connected in series to the network.

To satisfy these various possible embodiments of the method and conditions, the invention can be used to interface with different gas and water meters, provided that it is possible to transmit additional values via an IC card based on the transfer of values and through the storage an electrical energy meter that does not need to read measurements based on the following structures and principles.

The energy meter according to the invention measures voltage (V) and current (A) in real time, calculates the amount of electrical power (W) using the grid of consumed electrical power, measures the consumed electrical power measures the consumed electrical power per unit time, converts stored stored information in symbols, reduces the symbols according to the amount of power consumption per unit time in the symbol exchanger 10, and requires new information about the size of k reddites when characters are exhausted. Thus, the full credit balance information and power consumption information that the user needs to know is displayed on the LCD screen 17.

When the latest credit amount information is converted to symbols, the user is informed by an audible alarm for an audible frequency. Accordingly, credit values are recharged. When the hidden credit amount information is used up, the power source is disconnected from relay 1.

Through the modulated table (MT) 11, through which it is possible to differentiate the use of electrical power by at least five levels in percent, the real-time clock (RTC) differentially applies different levels of electrical power in percentages, such as 50, 75, 100, 200 , 300% according to the reporting periods and reduces the amount of credit information.

Although the same electric power is used per unit time, the SVM loan amount is reduced differentially after TE 10 applies a multi-stage electricity tariff through a program for the reported periods defined by the MT loan. This way the supply and consumption of the electric power are well balanced. The reduced utility in accordance with the consumer's selective consumption is determined by a multi-tiered system of tariffs for electric power. For example, the night time reduction during which power consumption drops, the electricity provider can save on the cost of the electricity supplied. When offices intensively use air conditioners in the summer, an additional cost overrun is charged and the heat storage system is charged. Accordingly, it may be possible to determine the diminished benefit to such an electric power consumer as a private house or establishment.

The electrical energy storage meter according to the invention has a data encryption structure in which the CNC 162 and the internal memory cannot be read by an unauthorized person, thus protecting the stored values from tampering and decryption. The electrical energy storage meter consists of a secret access module (SAM) 164 into which the secret internal key (CT [n]) and the encoding algorithm can be entered, and the storage module (SVM) 166.

If the hacker is destroyed or decrypted to counterfeit the loan amount information, the encoding key and the SAM and SVM encoding algorithm cannot be detected. The SAM, SVM, and master key (Mk) of the host computer identify each other. Thus, SAM and SVM can transmit and store credit amount information through the process described using the master key. SAM and SVM can store credit amount information and additional value information in the IC card using the master key.

When the IC card is inserted into the electrical energy meter, the response of the reset signal (ATR) is obtained by sending the reset signal to the card, the IC card and the terminal are mutually identified, the credit amount information is changed by SVM and SAM, whereby credit amount information is calculated taking into account the legal use of the IC card. Credit amount information is recorded using the stand-alone encryption key (MK) at the output. Thus, it is impossible to increase the loan amount. All processes are in accordance with the international standards ISO 7816 Part 1, Part 2, Part 3, Part 4, Part 8, as well as Part 10, and are physically standardized with the electrical signal, the logging link, and the coding process. At least two coding keys are stored as requested by the manager. One encryption key is updated remotely at a specified time. The coding key is selectively used. In this way, the misuse of the loan amount is avoided.

The transfer of the amount of credit and of the additional value and the control of the illegal use of the values are carried out through the network modem. The power consumption sensor circuit is provided and the power usage information is stored in a Local Power Supply (NVM) 15 so that illegal use of the power is monitored and punished without visiting the place where the power meter is installed. energy, and without checking the seller. All circuits can be monitored periodically by LS and AS, thus making an electronic sale without verification by the retailer.

The energy storage meter has a 3-byte serial number (SVPMSN). Network modem 13 is connected to LS by a modem identification number (MID) address of 1/256. When the server of the seller or distributor of electrical power sees a request for value transfer, it initiates a short-range connection to the stored electrical energy meter according to the addressing process for selecting the M - ID of the symbol. The symbol requires the transfer of the loan amount through the ARS connection of the seller or distributor of electrical power by telephone or internal digital telephone 20 and keypad 21, selecting the seat by credit card or bank account, to pay the transformed amount of the credit for electrical power. . The credit management server then requests the credit transfer through AN, which is provided by the server of the credit card company. The power provider's server, managing the loan amount, calls M-ID through AS and LS, transmits the loan amount to SVPM and saves the transferred loan amount by performing the above stored method.

LS checks the status of power consumption by consecutively crawling 2546 stored value symbols of electrical power through a network modem connected to the mains 117 / 220V over a maximum distance of 3 km. LS consecutively calls the addresses 1/256 ... n / 256 of SVPMs, checks and checks the status of changes to the SVPM's real-time clock, controls the modulating flow system, checks the CSN on the card, maintains the balance of the loan amount, checks for availability illegal and abnormal use of electrical power, as well as reports on the fall in load of consumed electrical power by days, weeks or months, thus determining the total amount and estimating the consumption of electrical power. The collected and calculated results are used as principles in negotiating the prices of purchased electric power and specifying the prices of the offered electric power.

When transferring and storing credit, the gas meter, water meter, heat meter and other non-watt meters contain a meter that works autonomously using the IC card without selecting the communication line, as they are of poor quality and their construction is very complex.

When the transmitted value information via the energy storage meter is stored in the IC card and the IC card is placed in the meter, gas meter and heat meter, the value information is stored in each one. The symbols are alternated through the process of storing the loan amount. When the credit amount information is exhausted, the shut-off valve for gas, water, heat and hot water closes. The efficiency of the invention is enhanced by the value-add function, which enables the use of a value transfer and the electrical energy meter along with the value-added service. The additional value is generated and transmitted through the method of generating and transmitting the amount of the loan. The extra value is stored in the IC card instead of in the energy meter. The value added information for gas, water, hot water and heat is stored in the IC card by performing the above methods, and can be transmitted to the IC card of standalone water and gas meters for which it can be applied IC card according to Korean Patent Applications 98-6947 and 98-6948.

The request for transfer of the amount of credit and processes in the network modem is further described with reference to FIG. 6.

The contracting party issues the IC card using the master key of the IC card 51 of the power distributor control system 50.

After depositing the loan amount for electricity, hot and cold water, gas and heat by hand or by credit card with the provider, the first loan amount is saved in the IC card. The amount of credit for the electrical power in the card is stored in the energy storage meter by inserting the IC card into the user's energy meter 55. When the IC card is placed in the gas meter, water meter, hot water meter, in the heat meter of the user 55, the amount of credit is stored in each of the meters. After storing the first loan amount, the next loan amount / value addition is saved using the value transfer method, using the network power modem. The transfer and storage of value can be accomplished through the use of telephone, Internet, P-ATM (EMV'96), as well as using the electrical energy meter. Methods for transferring and storing values are performed using the specified coding algorithm. The amount of credit / value added is channeled as follows.

The recorded information of the contracting party is taken from the database to the contracting party in the main server of the power distributor 50. Payment by the bank or the VAN company is guaranteed by selecting the direct payment number or credit card number, or the bank account number of the user. Credit Amount Information is encoded using the SAM Master Key. The ID of the characteristic value of the electrical energy storage meter is transmitted over the AS and LS networks. The SAM and the master key are identified when the amount of credit / value added information is transmitted. The Local Monitoring Unit (LS) records the decline in load on power consumption over the hours, days, weeks, or months received from the stored electrical energy meter, controls the status of electricity use, and the credit balance of every hour or daily, regulates time, reduces load on electrical power, using modulation and program, and controls illegal and abnormal use of electrical power. Also, the calculation of the amount of money is performed by the system of money supply 54 of the supplier 53 and the distributor 50 of the electrical power by a method similar to the above method.

Figure 7 shows the appearance of an electrical energy storage meter according to the invention.

The electrical energy storage meter according to the invention includes an LCD display 17 at the top of the front surface and an inlet and outlet terminal 66 at the bottom of the front surface. The inlet and outlet terminal 66 is connected to the electrical power supply and outlet network and is enclosed by a housing 64 preventing unauthorized use. The digital internal telephone 20 and the transfer request keypad of value 21 are located on the upper surface of the housing 64 to prevent unauthorized use. The slot 60 for the IC card in which the card is inserted is formed on one side of the energy meter. The amount of credit is stored in the IC card and read from the IC card when it is located inside the slot 60 intended to fit the IC card. Thus, the sealing member 62 for detecting unauthorized use / destruction of the energy meter, sealing it so that the electrical power cannot be used illegally, is part of the energy meter.

As noted above, the invention is described only when using the energy storage meter via a network modem. The mutually necessary information can be exchanged through the network modem connection between the server and the terminal. The main telephone network, the radio network and the TV cable network may be used instead of the mains power. As stated above, according to the invention it is possible to reduce the cost of personal visits by eliminating the metering processes for electricity, gas, water and heat meters, the cost of calculating, printing and sending bills, and and for postage bills.

It is also possible to reduce losses due to uncollected accounts and liabilities, as well as to the translation of additional value before being prepaid for the amount of credit through a credit card or a bank account.

Therefore, the electricity supplier can give a high added value.
