Description

Description of the invention

This invention relates to a fundamentally new value-storing electricity meter, and more specifically to a value-storing method 2, by which a server of an electricity supplier or electricity sales intermediary transmits a certain value via a modem connected to the power grid and stores this value in a value-storage module ( M33) or in a chip card, as well as an electric meter for advance and direct payments, which does not require measurements.

Until now, all power-consuming facilities, such as homes, offices and public buildings, have used a traditional power/time meter to measure the amount of power consumed per hour by an electrician over a period of time. Such a first-generation electric meter is very difficult to manage, and it requires high costs, when the electrician goes around the places where the electric meters of houses and institutions are installed and measures the difference between the amount of energy consumed at the time of the previous measurement and the amount of energy consumed at the time of the current measurement, that is, the amount 12 consumed energy per month or for a certain period. The supplier calculates the electricity supplied and consumed, and the customer is printed and mailed a bill after performing the calculation process, such as entering data and calculating the amount of energy consumed, and the customer takes a payment request and makes a payment, and the request is processed. To process arrears and non-payments, you need to send a repeat invoice.

Since thieves posing as electricians have appeared, and the cost of measurements is a significant part of the cost of electricity supply due to the increase in the cost of electricians, now a new method of measurement, which is not widely used today, is considered a remote metering electric meter, which is a product of the second generation. By using a remote metering electric meter, you can reduce personnel costs. However, it is necessary to computerize the amount of electricity consumed each month, to send a bill by mail, and (3) to process arrears. In particular, the supplier and consumer avoid the use of remote metering electricity meters for gas meters and water meters, which require additional energy and lines such as telephone lines or radio.This is due to the increase in cost caused by the interaction between gas and water meters, the server of the remote measurement center and - the equipment, as well as the operation of the communication equipment to implement the additional communication function for the remote measurement.

So, you can consider a third-generation electricity meter with chip card payment, which does not require visual measurements. An electricity meter with chip card payment can to some extent solve the problems associated with the use of electricity meters of the first and second generations. However, the efficiency of the electric meter with payment by chip card depends on how to carry out the processes of reloading and - calculation of information about the value in the chip card. In particular, when the power is turned off due to the complete consumption of information about the values on the chip card, unexpected accidents may occur.

The first goal of the present invention is to create methods for transmitting and storing values, with the help of which the server of the electricity supplier or electricity sales intermediary communicates with 50 electricity meters that store the values of the respective users, stores the values in the value storage module (M33) in made in accordance with the present invention to the electricity meter, which stores the value, transmits to

With" chip card and stores in it additional credit information about the value. In this way, suppliers or intermediaries create high added value for consumers, increasing management efficiency and significantly reducing the price of electricity.

The second purpose of the present invention is to create a method of storing values on a chip card, with the help of which 7 could use credit information about the value transmitted through a modem connected to the av! electricity grid, with all meters in homes and factories, such as gas meters, water meters and heat calorimeters, installed and operating autonomously. o A third object of the present invention is to create a value-storing electricity meter that would allow an electricity supplier or electricity sales intermediary to improve control efficiency by communicating with the main host of the relevant institution via a modem connected to the power grid and transmitting credit information about the value to the chip card with its storage in the card. In this way, it is possible to reduce the price of electricity for consumers by significantly reducing the unforeseen costs associated with the supply of electricity and bypassing the Step of entering and calculating the amount of electricity consumed during a certain period by using a server to print bills and send bills

GF) by mail and their calculation.

The fourth objective of the present invention is to create an electric meter that stores the value, which would allow to completely solve all the problems associated with electric meters of the first, second and third generations, to quickly and easily reload the value and load an additional value into the chip card using channel 60 loading value. Thus, a value-storing electric meter can be applied to a wide variety of meters, such as gas meters, water meters and calorimeters. Therefore, it is possible to maximize the efficiency of various types of business.

Accordingly, in order to achieve the above goals, a value-storing electric meter was created, made with the possibility of establishing a connection with the server of the electricity supplier through a modem, because it is connected to the power grid and included in the electric meter, storing the value in the value storage module installed in the electric meter, calculating value depending on the amount of consumed electricity and stopping the supply of electricity when you have completely consumed the credit value.

Here, this image is limited to the electricity meter for convenience. In addition, everyone has

In the processes of information exchange for the transmission and storage of values according to this invention, the main encryption algorithm is used - the triple data encryption standard. Communication between the host server and the electricity meter terminal is carried out in the following way. First, the task of creating a session key (Kv) is performed on the server and on the terminal. An encryption algorithm is applied to the session key - the triple data encryption standard. In addition, if it is necessary to create a signature, a code is used

Ф) authentication of the message with the combination of cipher blocks using the triple data encryption standard. When the values are stored on the terminal of the electric meter, the storage of values, the table of calculation of electricity consumption modes, the payment per unit of electricity and the time it will be necessary to correct are stored. When the value is read from the terminal, the credit balance, the details of the date, month and year of consumption, the calculation table of the electricity consumption modes, the payment per unit of electricity and the hours according to the timer are read, thus providing information to detect unauthorized use.

First, before describing the method of transmitting and storing values according to the present invention, below 65 examples of signature generation and the encryption algorithm used in this method will be described with reference to Fig.4.

After completing the task of creating a session key (Kv) on the server and terminal during communication between the server and the electric meter that stores the value, an encryption algorithm is applied to the session key (Kv) - the triple data encryption standard. For the signature generation task, you can

Use a message authentication code with a combination of cipher blocks using the triple data encryption standard. Below, the generation of the signature and the encryption algorithm will be described in more detail in relation to Fig.4.

To generate the signature, the output data values are made multiples of 64 bits by applying padding with insignificant information in Stage 1. These are O., ..., and O. in Fig.4. In Stage 2, the 64-bit data values (OM) are subjected to 7/0 E-encryption using the triple data encryption standard according to the input key (DO).

The value of the signature at Stage C is 04,.....and Oh. At this time, the values obtained by adding the corresponding data values (Ou) to the signature values (Om)3) are subjected to E-encryption, except for the first value of the signature 01.

For encryption, the value of the output data is made a multiple of 64 bits by applying padding with insignificant information in Stage 1. These are OO, ... and OK. At Stage 2, the triple data encryption standard is used for E-encryption. Encrypted messages are Ow... "Ow on Stage 3.

The main key (KN) of the host, the internal secret key (KT) of each terminal and the secret session key (SK) used in the communication process, each of which has a multiple of 128 bits, are used. The session key of the terminal (Kv) is generated from the internal key of the terminal (KT). The host master key (HK) and terminal internal key (KT) are randomly selected from the given sets.

The internal terminal key (KT) is generated by encrypting the terminal identifier using the triple data encryption standard using the host's master key (MK). The internal key is stored on the terminal at the Generation Stage and is generated at the host at the initial Communication Stage. That is,

KTUEpsguri (IU, KN) (KT is an encrypted identifier and KN - adj, translator).

The session key (K5) is generated by encrypting random numbers K, which are generated in the host using the triple data encryption standard using the terminal's internal key (KT) each time a connection is made. All encryption is done using the session key (Kv) in the communication process. and)

That is, Ke-Epsgury (K, KT) (K5 is encrypted K and KT - translator's note).

In this invention, algorithms are adopted for 1) management of the storage of values, 2) management of differential payment modes depending on hours, days, months and seasons and 3) management of the use of "- zo during days, weeks or months and checking the timer readings (using observation for unauthorized consumption of electricity). They will be described in relation to Fig. 1-3. with

First, the value storage management process will be described in relation to Fig.1. with

Step 10: The host generates a first batch of random data (K1, K2 and n) and sends this first batch of random data to the terminal. The session key is generated using the key generation algorithm using the internal secret key of the terminal (KT(pI). That is, Ke-Epsgury (K1, KTIpI) (Ke is encrypted K and KtTIp) - note, translator). For comparison, during terminal identification, the first signature value 51 - Zid (K2, Kv) is generated using the signature generation algorithm. The terminal receives the first portion of random data (Ki, K2 and n) and generates a session key as it is done in the host using the terminal's internal secret key (KT(pI). That is, Ke-Epsgury (K1, KTIpI) (Ke is an encrypted K « and Kp) - adj., translator). from c Step 12: The terminal generates a second signature value 51(-51id (K2, Kv) using the signature generation algorithm, generates a second portion of random short circuit data and sends 9511 and short circuit to the host. ;" Step 14: The host can identify the terminal by comparing 51A of 51. After identification of the terminal, the host generates the third value of the signature 52p-51d (NAKZAEpAtpi, Kv) and sends 521 to the terminal with an encrypted

The total amount of information about money (EpAtp). Here H is a header representing the command to store -I values. The terminal generates the fourth value of the signature 52(-5id (NAKZAEpAtpi, Kv) and identifies the host by comparing 52 with 52. o Step 16: After identifying the host, the terminal increases the value, encrypts VaiapseniO (result identifier 2) - translator's note) as M-Epsgury ( VaiapseniO, Kv) (M, which is equal to the encrypted result and 5r identifier and Kv) and sends the encrypted value of M to the host. The host once again identifies the terminal by decoding the encrypted value M as Vaiapse--O1-Oesguri (M, Kv) (balance identifier - decoded M as and Ke - translator's note) and comparing IC (identifier!y - translator's note) with IU (identifier).

After the terminal is identified, the result is stored in a log file.

The process of managing differential payment modes based on hours, days, months and seasons of the year (payment system) will be described in relation to Fig.2.

Step 20: The host generates the first portion of random data (K1, K2, and n) and sends this first portion of random data (F, data to the terminal. The session key is generated using a key generation algorithm using a secret key (KTp)|). That is, Ke-Epsguri (КИ, Ки!) (Кв is encrypted K! and КТИп) - translator's note). For comparison, during terminal identification, the first signature value 511-519 (K2, or Kv) is generated using the signature generation algorithm. The terminal receives the first portion of random data (K1, K2 and n) and generates a session key in the same way as the host, using the terminal's internal secret key CT(nI). That is, Ke-Epsgury (K1, КтТИпИ) (Ke represents encrypted К1 and КТИп) - translator's note).

Step 22: The terminal generates a second signature value 51(-51id (K2, Kv) using the signature generation algorithm, generates a second portion of random data (RDR) and sends 51 and RDR to the host. 65 Step 24: The host can identify the terminal by comparing 51A of 51. After identifying the terminal, the host generates the third value of the signature 52p-5id (NiKkZ-ModenOpii, Kv) and sends the third value of the signature to the terminal together with the mode information and the information about the payment for the unit of electricity. The terminal generates the fourth value of the signature 521-51d ( NAiKZ-ModenOpii, Kv) and identifies the host by comparing 52 with

Step 26: After identifying the host, the terminal transforms the payment system, encrypts VaiYapseniO (balance plus identifier - translator's note) as M-Epsguri (VaiapseniO, Kv) (M, which is equal to the encrypted result and the identifier and Kv) and sends the encrypted value of M to the host . The host also simultaneously identifies the terminal by decoding the encrypted value M as VaYapseIiO1-UOesguri (M, Kv) (balance'identifier'-decoded M and Kv - translator's note) and comparing IC" (identifier - translator's note) with IO (by identifier) After the terminal is identified, the balance is stored in a log file.

Finally, the process of managing usage over days, weeks, or months and checking the timer readings (used to monitor unauthorized power consumption) will be described in detail with reference to Fig.3.

Step 30: The host generates a first batch of random data (K1, K2 and n) and sends this first batch of random /5 data to the terminal. The session key is generated using a key generation algorithm using a secret key (KT(n!), that is, Ke-Epsgury (K1, KTp)) (Ke represents encrypted KI and KTIp) - approx. translator). For comparison, during terminal identification, the first signature value 5y-5id (K2, Kv) is generated using the signature generation algorithm. The terminal receives the first portion of random data (K1,

KO and n) and generates the session key in the same way as the host, using the internal secret key 20 of the KtpI terminal). That is, Ke-Epsgury (K1, Kp) (Ke represents encrypted K1 and KTIp) - approx. translator).

Step 32: The terminal generates a second signature value 51(-51id (K2, Kv) using the signature generation algorithm, generates a second portion of random data (RDR), and sends 51 and RDR to the host.

Step 34: The host can identify the terminal by comparing 51A with 51. After identifying the terminal, the host generates a third signature value 52p-51id (Н-КкЗТите, Кв) and sends the third signature value to the terminal сх об along with the value of TITE (time - translator's note ). The terminal generates the fourth value of the signature 521-519 (NAKZyaTite, Kv) and identifies the host by comparing 52 with 521. i)

Step 36: After identifying the host, the terminal encrypts the information file (IPIO), including usage details (09), table of differential payment modes (ModetB), terminal time (Titeg), balance (Viaapse) and identifier (IB). That is, the terminal encrypts the information file (po) using M-Epsgury (po, Kv) and sends the encrypted value of M to the host. Here Ipo-Y od-ModetV "VaIapsetiIU". The host again identifies the terminal by c decoding the encrypted value M using Ipio-Huesgury (M, Kv) and comparing IC" with IO. After c identifying the terminal, usage over days, weeks or months and timer readings are copied to a log file and verified. o

As mentioned above, the data transmission and storage encryption algorithm used in the present invention has been described. In order for it to be applied in a real electricity meter, the following issues need to be considered.

The maximum number of electric meters that store values that can be connected to one reference transformer is limited to 256. In the reference transformer for converting 3.3 kilovolts into voltage "

Power supply 2208, one unit of local service and observation (LSS) controls 250 electric meters, which store values with c. VOCs with different serial numbers are attached to the other side of various poles. transformers One block of regional service and surveillance (OSS), connected to a maximum of 256 LSOS, and? can control 65536 value-storing electric meters. When managing 256 VOCs, one local server in a tree structure can manage up to 16,000,000 VOCs. However, taking into account the performance and efficiency of the server, it is better to limit the maximum number of electricity meters that store values - AND managed by the local server. In the event that a signal with a voltage of 2208 passes through the transformer to the other side, the user of the modem connected to the power grid and the modem of the electricity meter are assigned a 3-byte identifier (IB). A channel scrambling modem protects the encryption algorithm and encryption key, prevents their assignment, or can selectively use a secure access module (SAM), which is a user identification module (UI) chip card. Calculation of the amount of used electricity, accumulation of markers and display can be carried out with

By using an additional microcontroller. At this time, it is checked whether there are any obstacles to control the display of data on the LCD display and the calculation of the amount of electricity used when the electricity meter communicates with the host. It is believed that there is a time limit when providing time information to an electric meter. That is, when it is assumed that the transmission of time information to one family takes one second, the transmission of time information to 3,600 families takes one hour. A clock is loaded into the electricity meter

F) real time, and differential payment modes are applied according to time periods. Clock time is constantly adjusted and monitored. Unauthorized consumption of electricity is monitored, or digital "sealing" is used to intercept electricity or hack by connecting a modem connected to the power grid to a personal computer.

Digital "sealing" is carried out in a systematic way using a combination of software and hardware. Digital "sealing" to control unauthorized use of electricity is carried out by means of a method in which the terminal transmits details of the amount of electricity used at a certain point in time for a certain period of hours, days, weeks or years to a server as 65 2.44 kilobytes of information. The server records information in the database, compares the recorded information with the information that will be transmitted at the next moment in time, and compares the result of the comparison with the total amount of consumed electricity for the same period. It is believed that the supply of voltage to the output terminal in the state where the relay switch with mechanical blocking stops the supply of electricity indicates the secret use of electricity. Accordingly, emergency information is sent to the server.

All the details of electricity usage on the server can be used as a basis for concluding a price agreement favorable to the conclusion of a re-contract by applying a reserve percentage in the purchase of electricity by approximating the electricity used for a certain number of days, months or quarters based on the total amount of electricity consumed for a certain number of hours, days, months or quarters. 70 When the circuit breaker stops the supply of electricity due to the exhaustion of the stored value of the credit amount of electricity, interruption of the overload current, interruption in a special case or the use of electricity by branching the power supply at the front end of the meter, unauthorized consumption of electricity is determined by the method of checking for the presence of voltage load.

The credit value is transmitted and stored in the electricity meter, gas meter, water meter and calorimeter using a modem connected to the mains. The credit value is stored in MZ3, and other values are stored in the corresponding areas of the chip card's electronic wallet.

Next, the devices and operation of the electric meter, made taking into account the above-mentioned issues, will be explained in more detail in relation to Fig. 5-7.

Figure 5 shows an electric meter that transmits and stores information about values through a modem connected to the power grid. In figure 5, the relay switch with mechanical blocking is a relay switch of the type of relay with mechanical blocking to stop the supply of electricity. The shunt resistor 2 measures the alternating current (AC) through the manganese resistance (Mp) of 0.um. When the relay switch is opened, the power consumption sensor Z determines normal use - when there is a "0" signal at the output of the sensor, and the fact that the terminals Iz and 1! shunted, and electricity is used secretly - if there is a "1" signal at the output of the sensor. Buzzer 4 requests a new credit value token on M33Z after i) exhaustion of the balance of the token exchange device, and generates an audible alarm, thus allowing to control the transmission and storage of information about the credit amount of electricity by the electricity user. The chip card 5 for storing credit and added values registers the serial number of the user's chip card "- zo "SNK) in the control database using the master key of the electricity sales intermediary controlling the electricity meter storing the credit value according to the present invention , and c checks for the presence of a registered legitimate SNK when the server is requested to transfer the credit c value, thus preventing illegal use of electricity.

Voltage divider 6 adjusts AC voltages 1178, 2208, and 2408 so that they are within the range of input voltages of the analog-to-digital converter (ADC). The voltage range is selected according to the ratio of two resistors connected in series. ADC 7 is a circuit for converting an analog AC voltage signal into a 16-bit digital signal. Analog-to-digital converter (ADC) 8 is a circuit for converting the alternating current signal passing through the shunt resistor 2 into a 16- or 20-bit digital signal. The working circuit of electricity consumption 9 calculates electricity (W) by multiplying the digital signal of the ADC 7 by the digital signal of the ADC 8 and converts the result of the multiplication with s into a ripple coefficient and a duration signal. The working circuit of power consumption 9 compares the phase

And the voltage with the current phase, calculates the angle of shift of these two phases and outputs the phase shift as a signal, applying such a thus, different modes of payment for cases where an inductive load is used. The token exchange device 10 reduces tokens according to the amount (Wh) of electricity consumed per unit time,

Requests new tokens from the 10-unit token store when tokens are exhausted in the exchange device -And 10 tokens, and reduces new tokens according to the amount of consumed electricity. When the storage of 10-unit tokens for MZZ is exhausted, 100-unit tokens are requested, which will be described below, and the storage of 10-unit tokens is filled again. Markers that are requested for MZZ 166 can be obtained 2) in the process of identification of MBD 164. The table of real-time hours and electricity consumption 11 implements 5or differential application of multi-stage payment modes for electricity according to 5095, 7590, 10096, 15095 and 20095 demand and consumption electricity based on real-time hours, including year, month, day, hours, minutes and seconds (YYMMDDYYYYYY).

The IC 7816 chip card reader and writer 12 is an eight-terminal communication port defined by ISO 7816 part 2 that has a power supply, a clock frequency, a digital input/output, an initialization signal and "ground" for synchronous and asynchronous communication with the chip card. Multi-purpose quantity values such as electricity, gas, water, hot water, heating (F, energy and pay TV services supplied on credit) are recorded on a single chip card by inserting a custom-made chip card into an electricity meter in a connected/ disabled state.

After recording the value transmitted from the gas service through the electric meter, which stores and transmits the value, because the chip card is pulled out, inserted into the gas meter, and the information about the value is transmitted to the gas meter, thus reducing the value on the card, which correspond to the amount of gas consumed.

Therefore, the electric meter that stores and transmits values can operate in the disconnected state.

Modem 13, connected to the power grid, exchanges data through the transmission line. Each modem is set to one of the 256 identification addresses of modems connected to the power grid (AMPE). AC and DC power source 14 supplies the operating voltage required by the value-storing electric meter of the present invention. A three-byte identifier, which is an internal number of the electric meter that stores the value, is written in the PZP during the generation of electricity. The long-term memory 15, which is composed of a flash memory, records the state of electricity consumption during a certain period, that is, detailed information on electricity consumption for 24 hours is determined by recording the amount of electricity consumed by the electricity meter, which stores the value as 16-bit information every sixty seconds, detailed information on electricity consumption for a week - by adding together seven total amounts of electricity consumed daily, and detailed information on monthly electricity consumption - by adding thirty total amounts of electricity consumed daily, monitors secret or unauthorized electricity consumption from a remote distance and carries out electronic "sealing". 70 Scrambled bus 16, which contains a central processing unit (CPU) 162, a secure access module (SAM) 164 for storing the encryption key and an encryption algorithm for storing the values of the amount of electricity provided on credit, and a value storage module (M3Z3) 166 for storing the values of the amount of electricity provided on credit prevents falsification and use of information on the amount of electricity provided on credit, and hacking and excludes the possibility of a cryptographic attack. The liquid crystal display (LCD) 17 displays the total credit value of the transfer status, the real-time power consumption status, and the total power consumption status, allowing the consumer to determine all of the above visually. The input and output terminal of LEP 18 consists of 15, 25, 2Y and 1Y for connecting the input and output power lines to each other and a cover to prevent physical interception of electricity.

Arrester 19 is a circuit for absorbing lightning discharges or impulse voltage.

An electric meter for measuring the amount of electricity of a certain type was described above. However, the electric meter according to the invention can measure electricity of at least two types if it includes a voltage divider b, ADC 7, ADCPS 8, a relay switch with mechanical blocking 1 and a shunt resistor 2 according to the type of electricity. That is, when combining the voltage divider, ADC,

ACDC, mechanical interlock relay switch and shunt resistor can selectively or simultaneously use at least two types of power sources with different voltages and additionally o measure and control the corresponding amounts of current.

The operation of a value-retaining electric meter having the above-described construction is described as follows.

As indicated by the electricity supplier or electricity sales intermediary, the credit value from the host is stored in the MZ3Z 166 of each terminal through the modem 13 connected to the power grid, using the method of storing the values of the amount of electricity provided on credit, each electricity meter calculates the fee according to the amount of consumed electricity, controlled by the working chain of electricity consumption c 9, compares the calculated fee with the summary information about the amount of electricity provided on credit, which is stored in MZ3Z 166, and calculates the fee using the exchange device 10. When there is a balance in MZ3Z 166 that is not exceeds a certain amount, the user is informed about the state of the balance by a buzzer sound. If the balance is insufficient, the credit value is transferred from the host to MZ3Z 166 using the above-mentioned method of storing the values of the amount of electricity provided on credit, or the supply of electricity is stopped by actuating the relay switch with mechanical blocking 1.

Information about the amount of electricity provided on credit can be stored in the MZ3Z 166 by communicating between the host and the terminal in the value-storing electric meter according to the present invention. However, "it is also possible to transfer the information about the amount of electricity provided on credit, which is stored on the chip card 5, to the MZ3Z3 and store the transferred information in the MZ3Z3 by inserting the chip card 5 for the electric meter, gas meter, water meter and calorimeter for seven or organization for which on ;" a value-storing electric meter according to the present invention has a certain legally appropriated amount of money recorded on it.

This means that the electricity meter according to the present invention displays information such as the monthly consumption amount and card balance on the LCD display 17 located therein by using a certain amount of electricity in the range of values recorded in the MZZ3 and sends a sound signal buzzer 4 when there is a balance on the o card that does not exceed a certain amount. Thus, the user asks the server about the transfer of the credit value. The credit value is automatically recorded on the account of the bank with which the contract was previously concluded, or is repaid by credit card. The value of the amount of electricity yu is received in real time through the power transmission line and stored in MZ33 166. The value shk decreases according to the scale of electricity consumption.

Thus, the electricity supplier and electricity sales intermediary can save costs by eliminating the processes of meter reading, entering and calculating the amount of electricity used, and printing and mailing the bill. The electricity bill is paid in advance.

Accordingly, the process of reloading debts is excluded. It is also possible to reduce (F, the electricity bill due to the profit received as a percentage of the prepayment, the application of differentiated payment modes according to the period of electricity consumption and cost savings due to the difference between the purchase and sale price of electricity. The electricity supplier can run a business with a large added cost

In order to prevent the use of a counterfeit card other than a chip card legally issued by an electricity supplier or electricity sales intermediary, the electricity meter is loaded

MBD 164 for card identification. When a card is inserted into the terminal, the terminal and the card carry out mutual identification. When the terminal transmits information about the amount of money on the card as information about the amount of electricity 65 provided on credit, the terminal functions according to the encryption process shown in Fig.1.

Thus, the use of a counterfeit card is prevented. To prevent a hacker's cryptographic attack,

for example, dismantling a value-storing electricity meter in order to tamper with a terminal or card, a method of destroying the encryption key when dismantling the meter, thus blocking the terminal, can be considered. However, the encryption algorithm and the encryption key inside the terminal only have a quantity reduction key, in which the information about the amount of electricity provided for credit is reduced according to the amount of electricity consumed. Thus, it is not possible to increase the amount of money or information about the amount of electricity provided on credit. Specifically, in the present invention, when a user/consumer contacts an auto-routing server using a telephone or digital intercom to request a credit transfer, the amount of electricity consumed is redeemed at a choice of 7/0 by using a credit card or bank account. The value transfer process begins within those limits where payment is guaranteed. The process can also be done online. In particular, it is possible to automatically transfer a value when the value stored under an automatic account transfer agreement between an electricity supplier or an electricity sales intermediary and a financial institution is reduced to a certain value for people who have never used a computer before 7/5 or data transmission network. In particular, in the case of making a payment request using the ZET secure electronic transaction protocol with a direct payment card, the server acting as an e-store can enter the details of the transaction into a digital envelope (DC), which indicates the details of the transaction. Thus, the trading process cannot be tampered with and cannot be fabricated.

The process and conditions of the above invention will be described in detail below. 1) Processes of generation, transmission and storage of values about the amount of electricity provided on credit.

Information on the amount of electricity provided on credit is generated by communicating and working with the user's control database using the master key (MC) of the electricity supplier or electricity sales intermediary. The identification number of the user requesting the modem connected to the power grid, the local network, is selected through the regional service and surveillance unit (OSS) and the local service and surveillance unit (LSS). After completing the request for the user identification number and the connection, the legitimacy of the server and the terminal is identified using i) the aforementioned identification process. After the identification is completed, the requested information about the amount of electricity provided on credit is transferred. Information about the amount of electricity provided on credit, transmitted through the power line, is stored in the value storage module (M33). "- zo 2) Processes of transfer and storage of supplemented values.

The effectiveness of the present invention is increased by adding the function of the transfer of supplemented values, which can be used in electric meters, gas meters, water meters, calorimeters and hot water meters, which are activated autonomously by a chip card without a separate communication line. Generation and the transfer of supplemented values is carried out using the above-mentioned generation processes and so on

35 transfer of values. The added value is stored in the chip card, not in the electricity meter. Information about it - additional values, for example, for the amount of gas, water, hot water and thermal energy stored in the chip card, can be used by inserting the chip card in water meters and gas meters that work in autonomous mode and are compatible with chip card as provided in Korean patent applications MoMo 98-6947 and 98-6948 filed by the same applicant. In this way, maximum control efficiency is achieved. "

C) Consumption of information on the amount of electricity provided on credit. Information about the amount of electricity provided on credit, stored in the MZZ 166, is reduced in the token exchange device (POM) 10 in accordance with the amount of consumed electricity. The marker decreases by ;" several milliwatts, several watts or several kilowatts per unit time interval. When the marker of the minimum unit is exhausted, the information about the amount of electricity provided on credit is reduced by

By using the new token request process. -And 4) Differential application of electricity consumption rates.

The mode of electricity use, in which multi-level rates for electricity consumption are differentially applied in accordance with the time periods of working days and weekends, seasons of the year and months, in which, with the help of the program, you can select and automatically apply the amount of used electricity provided on credit. In the table of electricity consumption modes 11, it is possible to differentially apply different prices in accordance with time periods and features of demand and supply

Kc of electricity and supply and consumption of electricity, for example, with the help of a real-time clock (RTC), a 10095 daytime payment on weekdays, a discount of 7595 before and after hours on weekdays, a discount of 5095 at midnight, 20095 allowance during daytime working hours and the 30095th allowance from 14:00 to 16:00 in the summer, as the use of air conditioners increases sharply during this period. Thus, electricity consumption becomes the most profitable for each time period. Therefore, becomes the maximum

F) efficiency of demand and supply of electricity. Therefore, the electricity bill is reduced. ka 5) Balance check and automatic interruption of electricity supply.

Information about the amount of electricity provided on credit in MZ3Z3 166 is displayed on a display, for example, on a liquid crystal display, so that the user can check the balance at any time. When the amount of electricity provided on credit is exhausted, the token exchange device informs the user with a sound signal of audio frequency that the last tokens are used. If the credit value is not recharged before the last token is used, the power supply is stopped by applying an interrupt signal to a mechanically interlocked relay switch connected in series 65 TO the power line.

In order to meet the aforementioned various processes and implementation conditions, the present invention can be used with respect to various gas meters and water meters in which augmented values can be transmitted by means of a chip card based on an electric meter that transmits and stores the value for which there is no need to read the reading , based on the following devices and principles.

The value-saving electricity meter according to the present invention measures voltage (M) and current (A) in real time, calculates the amount of consumed electricity (MU) using the electricity consumption chain, measures the electricity consumption per unit time interval, converts the stored values into token, decrements the token according to the amount of electricity consumed per unit time interval in the token exchange device 10 and requests new information about the amount of electricity provided on credit when the token is exhausted. In addition, all the information that the user needs to know, such as the remaining credit amount of electricity and the state of electricity consumption, is displayed using the liquid crystal display screen 17. After converting the latest information about the amount of credit electricity into the form marker, the user is notified of this by means of a sound signal having a sound frequency. Thus, the credit value is recharged. When the information on the quantity /5 of electricity provided on credit is exhausted, the supply of electricity is stopped by turning off the relay switch with mechanical blocking 1.

In the mode table (TR) 11, which can differentially apply at least five power rates, the real-time clock (RTC) differentially applies multiple power rates, for example, 5090, 7595, 10095, 20095, and 30090, depending on the time period, and reduce the value of the amount of electricity provided on credit by 2%. That is, despite the fact that the same electricity is consumed per unit time interval, the credit value in MZ3Z3 decreases differentially, since

POM 10 applies multi-level pricing for electricity using the time calculation program defined in TR. Thus, electricity consumption becomes the most profitable for each time period.

Therefore, the demand and supply of electricity become balanced. The system of multi-level pricing for electricity supplies gives an advantage in the form of discounts depending on the selective use of electricity by the consumer. For example, a discount during the night time, during which the supply of electricity is excessive, can i) reduce reserve prices for supply of electricity from the electricity supplier. When air conditioners are used intensively in the summer in offices, prices with a surcharge for electricity are applied, and a heat storage system is used. Thus, the consumer of electricity, both an individual and an institution, can be given an advantage in the form of a discount.

The value-storing electric meter according to the present invention has a scrambled data bus device in which the CPU 162 and the internal memory cannot be read by a layperson, which prevents forgery and cryptographic attack of the stored values. The value-saving electric meter consists of a secure access module (SAM) 164, which can be loaded with a secret internal key (KT(n)) and an encryption algorithm, and a value storage module (M33) 166. If a hacker or a person who has the intention is to carry out a cryptographic attack, they will disassemble the electricity meter in order to falsify the information about the amount of electricity provided on credit, they will not be able to see the encrypted key and encryption algorithm of the MBD and MZZ, MBD,

M33 and the master key (MK) of the host computer carry out mutual identification. Thus, MBD and MZ3Z can transmit and store information about the amount of electricity provided on credit using the aforementioned processes using the master key. MBD and MZZ can store information about the amount of electricity provided on credit and information about added values on the chip card using the main key. When the chip card is inserted into the electric meter, by referring the initialization signal to ;" the card receives a response to the initialization signal (ALL), the chip card and the terminal carry out mutual identification, the MBD and M33 exchange information about the amount of electricity provided on credit, and the amount of electricity provided on credit is calculated relative to the legal use of the chip card. -I Information about the amount of electricity provided on credit is recorded using a separately encrypted key (MC) of the requesting party. Therefore, it is impossible to increase the value of the amount of electricity provided in the credit. Such processes are carried out in accordance with part 1, part 2, part 3, part 4, part 8 and 2) part 10 of the IZO 7816 standard and include the physical standard, electrical signal, communication protocol and 5o encryption process. At least two encryption keys are stored at the administrator's request. One encryption key is renewed after a certain period of time has passed. The encryption key is used optionally. shk Therefore, fraudulent use of the values of the amount of electricity provided on credit is prevented.

Transmission of the values of the amount of electricity provided on credit and supplemented values and control over the legal use of the values are carried out through a modem connected to the power grid. The circuit of the electricity consumption sensor is provided, and the information about the use of electricity is recorded in the long-term memory (LMS) 15 to control the secret use of electricity and (F, punishment for illegal use, and at the same time there is no need to visit the place where the ka is installed electric meter, and check the lead or tartar seal.Such a circuit can periodically check the LSOS or OSS, thus performing the function of electronic "sealing" without actually checking the condition of the physical lead seal.

A value-storing electricity meter can have a 3-byte serial number of a value-storing electricity meter (SNEZ33). Modem 13, connected to the power grid, communicates with the LSOS using one of 256 addresses with a modem identification number (IMN). When the server of the electricity supplier or electricity sales intermediary sees a value transfer request, it establishes a close connection with the customer's electricity meter 65 storing the value according to the addressing process for selecting the customer's INM.

The consumer requests the transfer of the credit value by connecting to the server with the recognition of the address of the electricity supplier or electricity sales intermediary by telephone or digital intercom 20 and keypad 21, choosing the payment method - by credit card or through a bank account, and choosing to pay the transferred value of the quantity electricity provided on credit. Then, the server that manages the values of the amount of electricity given to the credit is requested to transfer the credit value using the assigned standard number provided by the server of the company that issues these credit cards. The server of the electricity supplier, which manages the credit values, requests the INM through the OSS and

Los, transmits the credit value to the value storing electric meter and stores the transferred credit 7/0 Value by performing the aforementioned value storage processes.

The LOS continuously monitors the state of electricity consumption for up to 256 electricity consumers using value storage through a modem connected to the power grid, connected to the power supply line at 117-2208 at a maximum distance of Zkm. The VOC sequentially queries electric meters that store values at the address 1/...п/256, checks and rechecks the mode of the 7/5 pricing system, checks the serial number of the card, makes a backup copy of the balance of the amount of electricity provided on credit, checks the availability secret and unauthorized electricity consumption and uploads reports on electricity consumption for days, weeks or months, thus summarizing and estimating electricity demand. The results of the summation and evaluation are used as guidelines for the discussion of the electricity purchase price and the re-examination of the electricity supply price.

To transfer and store the credit, gas meters, water meters, heat and hot water meters, other than electric meters, consist of a meter that works in autonomous mode by using a chip card without a separate communication line, since the installation conditions of these meters are very poor, and the construction of the line is very complicated. When the information about the supplemented values transmitted through the value-storing electric meter is stored on the chip card, and the chip card is inserted into the water meter, the gas

Db Meter and heat meter, each meter stores information about added values. Tokens are reduced using the same processes of reducing the amount of electricity credited. When i) the information on the amount of electricity provided on credit is exhausted, the valve is closed to stop the supply of gas, water and heat. The effectiveness of the present invention is increased by the function of the transmission of supplemented values, in which it is possible to use an electric meter that transmits and stores values, together with the service of supplemented values. Added value is generated and transmitted using the same credit value generation and transmission processes. The supplemented value is stored on the chip card, not in the electricity meter. Information about added values, for example, for gas, cold and hot water, with heat, is stored on the chip card using the above processes and can be transferred to water and gas meters that work with chip cards in offline mode and that support the use of chip cards provided for in patent applications of Korea MoMo 98-6947 and 98-6948. M

Below, in relation to Fig.b, requests and processes for transmitting information about the amount of electricity provided on credit in a modem connected to the power grid will be described.

The consumer chip card 52 is issued to those who wish to receive such a card by using the system administrator chip card 52 with the master key at the electricity sales intermediary 50. After repayment at the " place of credit value, for example, for electricity, gas, cold and hot water and thermal energy with cash or credit card, the first credit value is stored on the chip card. The credit value is stored in the electric meter by inserting a chip card into the electric meter, which stores the value, ;" user 55. When the chip card is inserted into the gas meter, water meter, hot water and thermal energy meters of user 55, the credit value is stored in each meter. After saving the first credit value, storage of further credit/supplemented values is carried out by means of the process of -I transfer of values using a modem connected to the power grid. The transfer and saving of values can be carried out by using the telephone, the Internet, a personal device for reading cards (EMU'96) and an electric meter that stores values. The processes of transmission and storage of the value are carried out using the aforementioned encryption algorithm. The transfer channel of the credit/supplemented value is as follows. Information from the user's records is taken from the user's database on the host server of the electricity sales intermediary 50. Payment by a bank or company with

A dedicated computer network is guaranteed, and the user chooses one of the numbers - for example, a credit card number, a direct debit card number or a bank account number. Information about the amount of electricity provided on credit is encrypted with the main key of the MBD. The identifier of the User's electricity meter, which stores the value, is requested through the OSS and VOC networks. Mutual identification is carried out

MED and primary key. The credit/recharge value information is then passed. Block of local

F) monitoring (LOSS) downloads a record of electricity use for a certain number of hours, days, weeks or months from the electricity meter, performs hourly or daily monitoring of the state of electricity use and the balance of the credit value, resets the time, loads the mode and program of the use of electricity and controls clandestine and unauthorized use of electricity. In addition, the amount of money is calculated between the amount of money calculation system 54 of the electricity supplier 53 and the electricity sales intermediary 50 using a method similar to the above-mentioned processes.

Fig. 7 is a three-dimensional perspective view of the external form of a value-storing electric meter according to the present invention. The electric meter storing the value according to the present invention includes 65 LCD display 17 in the upper part of the front surface and the input and output terminal 6b in the lower part of the front surface. The input and output terminal 66 is connected to the power supply line for the input and output of electricity and is closed with a cover 64 to prevent the secret use of electricity. On the upper surface of the cover 64, in order to prevent the secret use of electricity, a digital intercom device 20 and a keypad 21 for requesting the transmission of values are provided. In addition, there is a chip card slot 60 on one side of the electric meter, into which a chip card can be inserted. The credit value is stored on the chip card and is read from the chip card when it is in the chip card slot 60. In addition, a part of the electric meter is a sealing unit 62 to control the secret use and disassembly of the electric meter, which is designed to seal the electric meter so that electricity cannot be used secretly. 70 As described above, this invention has been described only with respect to a value-storing electric meter which operates via a modem connected to the mains. The server and the terminal can exchange the necessary mutual information by means of communication through a modem connected to the power grid. Instead of a power line, you can use a regular telephone line, a radio line, and a cable TV line.

As mentioned above, according to the present invention it is possible to reduce the costs of staff visits by eliminating the process of reading meters, for example electricity, gas, water and heat, computer processing costs, printing and mailing of bills and postage. .

In addition, it is possible to reduce losses due to uncollected bills and arrears and add value because the amount of electricity provided on credit is paid in advance by credit card or from a bank 2o account. In this way, the electricity supplier can get a lot of added value.
