Description

METHOD TO TRANSMIT AND STORE VALUES AND METER OF ELECTRICAL ENERGY STORAGE OF SECURITIES THAT USES THE SAME TECHNICAL FIELD The present invention relates to an electrical energy meter for storage of values of a new concept, and more particularly, to a method of storing values by means of which the server of an electric power supplier or an electric power reseller transmits a value through a modem (modulator-demodulator) power line, and stores the value in a storage value module (SVM) or an IC card and an electric meter of direct and advance payments without requiring a measurement .

BACKGROUND OF THE INVENTION A conventional watt-hour meter to measure the amount of electricity consumed per hour in a certain period by a person who is responsible for measuring, has been used a lot in all the Ref: 12476 institutions that consume electricity such as a home, an office, and a public building. Such a first-generation electric meter or wattmeter is handled in a very complicated and expensive way, where a person who is measuring visits the sites in which the electric energy meters of homes and businesses are installed, and verifies the difference between the amount of energy consumed in the previous measurement and the amount of energy consumption at the measurement point in time, for example, the amount of energy in a month or in a certain period. A calculation of the supply and consumption results is completed by the supplier and an invoice is printed and sent to the consumer after performing a computer process such as a data entry and a calculation of the amount of consumption, a consumer takes a request for the receipt and makes the payment, and the processing of the request. The invoice must be sent once for the processing of late payments and non-payment. Since thieves have appeared who claim to be the people who measure, and the costs of measurement contribute to a large part of the Electricity supply costs due to the increase in personnel costs of the people they measure, a remote measurement electric energy meter that is a second generation product, is under consideration as a new measurement method and is currently not widely applied. It is possible to reduce personnel costs of people who measure using the remote measurement electric power meter. However, the amount of consumption each month must be processed by computer, the receipt or invoice must be sent, and the arrears must be processed. In particular, the operation of the remote measurement electric power meter with respect to the gas and water meters, which requires an additional power and communication line such as a telephone line, or a radio, are avoided by the supplier and the consumer. This is due to the rise in cost, caused by the operation between the gas and water meters, the server of a remote measurement center and the installation and operation of the communication equipment according to the addition of a communication function for remote measurement.

BEST MODALITY TO CARRY OUT THE INVENTION Hereinafter, a method for transmitting or storing values according to a preferred embodiment of the present invention, and the structure and operation of an electric energy storage meter, without the need for measurement, will be described in greater detail. visual by a person in charge of measuring, using the same. The present invention can be applied to an electric energy meter, a gas meter, a water meter, and a heat meter or calorimeter, using the direct payment and prepayment calculation methods mixed with a bag method electronics. Here, the present invention will be restricted to the electric power meter for convenience purposes. Also, in all processes of transmission and storage of values according to the present invention, a basic, triple-DES coding algorithm is applied. The communication between a server host and an electrical power meter terminal is performed as follows. First, a task key development (Ks) task is performed on the server and in the terminal. A triple-DES coding algorithm is applied through the session key. Also, when a task of making a signature is necessary, a CBC MAC is used using the triple-DES. When the values are stored in the terminal of the electric power meter, a storage of values, a table of calculation mode of use of electrical energy, a unit charge, and a time that are to be corrected are stored.

First, before describing the method for transmitting and storing values according to the present invention, the examples of the signature generation and the coding algorithm applied to it will be described hereinafter with reference to Figure 4. After that the task of realization of the session key (Ks) is performed on the server and the terminal through the communication between the server and the electric energy storage meter, the triple-DES coding algorithm is applied through the session key (Ks). The MAC CBC that uses the tpple-DES can be used for the signature generation task. Hereinafter, the signature generation and the coding algorithm will be described in more detail with reference to Figure 4. For signature generation, the original data quantities are made in multiples of 6 bits by means of the fill-in application. step 1. These are Di, ..., and DN of Figure 4. In step 2, the data values (DJ of the 64 bits are coded F, applying triple-DE ?, according to a key of input (K) .The values of signature are Oi, ..., and 0N from step 3. At this time, the values obtained by adding the respective data values (DN) to the signature values (0N-J except for a first signature value Oi , are coded F. For coding, the magnitudes of the original data are made multiples of 64 bits by applying the padding in step 1. These are Di, ..., and DN.In step 2, the triple-DES algorithm to the F-coding. The coded messages are Oí + ... + 0N from step 3. A master key (KH) of the guest, an intrinsic secret key (KT) of each terminal, and a secret session key (Ks), used in a communication process, each having a magnitude of 128 bits, are used. The intrinsic terminal key (KT) is generated from the host's master key (KH). The session key (Ks) is generated from the intrinsic terminal key (KT). The host master key (KH) and the terminal intrinsic key (KT) are arbitrarily selected from various groups. The intrinsic terminal key (KT) is generated by encoding the ID of the terminal using the triple-DE algorithm? using the master key (KH) of the guest. An intrinsic key is stored in the terminal in a generation step and is generated in the guest at an initial stage of communication. Namely, KT = Code (ID, KH). The session key (Ks) is generated by encoding random numbers R generated in the host by the triple-DE algorithm? using the intrinsic terminal key (KT) whenever communication is made. All encodings are made using the session key (Ks) in the communication process. Namely, Ks = Code (R, KT). In the present invention, the algorithms of (1) a value storage command, (2) a differential load mode control command based on hours, days, months or seasons, and (3) use during days, weeks, or months and the command of Chronometer information verification (abnormal periodic verification is adopted) are adopted. These will be described with reference to Figures 1 to 3.

First, the flow of the value storage command will be described with reference to Figure 1. STEP 10: The guest generates the first random data (Rl, R2 and n) and sends the first random data to the terminal. The session key is generated by the key generation algorithm using the intrinsic secret key (KT [n]). Namely, Ks = Encode (Rl, KT [n]). For comparison during a terminal authentication, a first signature value Slh = Sig (R2, Ks) is generated by the signature generation algorithm. The terminal receives the first random data (Rl, R2, and n) and generates the session key as it is performed on the guest using the intrinsic secret key of the terminal (KT [n]). Namely, Ks = Encode (Rl, KT [n]). STEP 12: The terminal generates a second signature value Slt = Sig (R2, Ks) by the signature generation algorithm, generates the second random data R3, and sends Slt and R3 to the host. STEP 14: The guest can authenticate the terminal by comparing Slh with Slt. When the terminal is authenticated, the guest generates a third signature value S2h = Sig (H + R3 + EnAmnt, Ks) and sends S2h to the terminal with the total amount encoded of money information (EnAmnt). Here, H is a header that represents the value storage command. The general terminal has a fourth signature value S2t = Sig (H + R3 + EnAmnt, Ks), and authenticates the host when comparing S2h with S2t. STEP 16: When the guest is authenticated, the terminal increases the value, encodes the Balance + ID as M = Encode (Balance + ID, Ks), and sends the encoded value M to the guest. The guest authenticates the terminal one more time by decoding the encoded value M as Balance '+ ID' = Decode (M, Ks) and comparing ID 'with ID. When the terminal is authenticated, the balance is stored in a log file. The flow of the differential load mode control command, based on hours, days, months, and seasons (the charging system) will be described with reference to Figure 2. STEP 20: The guest generates the first random data (Rl, R2 and n) and send the first random data to the terminal. The session key is generated by the key generation algorithm using the secret key (KT [n]). Namely, Ks = Encode (Rl, KT [n]). For comparison during the authentication of the terminal, the first signature value Slh = Sig (R2, Ks) is generated by the signature generation algorithm. The terminal receives the first random data (Rl, R2, and n) and generates the session key in the same way as the host using the terminal intrinsic secret key (KT [njJ. Namely Ks = Encode (Rl, KT [n] STEP 22: The terminal generates the second signature value Slt = Sig (R2, Ks) by the signature generation algorithm, generates the second random data (R3), and sends Slt and R3 to the host. Host can authenticate the terminal when comparing Slh with Slt When the terminal is authenticated, the guest generates the third signature value? 2h = Sig (H + R3 + Mode + Unit, Ks) and sends the third signature value to the terminal together with the mode information and the unit load information. The terminal generates a fourth signature value S2t =? Ig (H + R3 + Mode + Unit, Ks) and authenticates the guest when comparing S2h with S2t. STEP 26: When the guest is authenticated, the terminal converts a charge system, codes Balance + ID as M = Encode (Balance + ID, Ks) and sends the encoded value M to the guest. The guest authenticates the terminal one more time by decoding the value coded M as Balance '+ ID' = Decode (M, Ks) and comparing ID 'with ID. When the terminal is authenticated, the balance is stored in the log file. Finally, the flow of use during the days, weeks, or months and the chronometer information verification command (used in the periodic verification of abnormal use) will be described in detail with reference to Figure 3. STEP 30: The guest generates the first random data (Rl, R2 and n) and sends the first random data to the terminal. The session key is generated by the key generation algorithm using the intrinsic secret key of the terminal (KT [n]). Namely, Ks = Encode (Rl, KT [n]). The first signature value Slh = Sig (R2, Ks) is generated by the signature generation algorithm for comparison during authentication of the terminal. The terminal receives the first random data (Rl, R2 and n) and generates the session key as it is performed in the guest using the intrinsic secret key of the terminal (Kt [n]). Namely, Ks = Code (Rl, Kt [n]). STEP 32: The general terminal the second signature value Slt = Sig (R2, Ks) by the algorithm of signature generation, generates the second random data (R3) and sends Slt and R3 to the host. STEP 34: The guest can authenticate the terminal by comparing Slh with Slt. When the terminal is authenticated, the host generates the third signature value S2h = Sig (H + R3 + Time, Ks) and sends the third signature value to the terminal along with the time. The terminal generates a fourth signature value S2t = Sig (H + R3 + Time, Ks) and authenticates the host by comparing S2h with S2t. STEP 36: When the guest is authenticated, the terminal encodes an information file (Info) including the usage details (Log), a differential charge mode table (TB Mode), a terminal time (Stopwatch), the Balance (Balance), and ID. Namely, the terminal encodes the information by M = Encode (Info, Ks) and sends the encoded value M to the host. Here, Info = Log + TB Mode + Balance + ID. The guest authenticates the terminal one more time by decoding the encoded value M by Info '= Decode (M, Ks) and comparing ID' with ID. When the terminal is authenticated, use during the days, weeks, or months and the information of the Stopwatch is backed up in the log file and verified. The value transmission and storage coding algorithm applied to the present invention was described as mentioned above. In order to be applied to an actual electric power meter, the following points should be considered. The maximum number of electrical storage energy meters that can be connected to a pole transformer is restricted to 256. In a pole transformer to convert the supply voltage from 3.3KV to 220V, a local unit of service and Supervision (L?) manages 250 electric energy storage meters. The LSs that have different series numbers are connected to the second side of the various pole transformers. An area service and supervision unit (AS) connected to a maximum of 256 LSs can handle 65536 electric energy storage meters. When handling the 256 LSs, a local server in a tree structure can handle up to 16,000,000 ASs. However, considering the performance and efficiency of server, it is preferable that the maximum number of electric energy storage meters, managed by the local server is restricted. A 3-byte ID is given to a user of the general power line modem and the modem of the electric power meter (micom) for the case in which a signal goes over the pole transformer to the other side of 220V. A micom that has a collective busbar (bus) function protects a coding algorithm and a coding key, prevents appropriation, or can selectively use a secure access module (SAM) which is an IC card of a type of subscriber identification module (SIM). A calculation of the amount of electrical energy, a password tank, and a screen can be carried out using an additional microcontroller. At this time, it is verified whether the control of the LCD screen and the calculation of electric power usage when the meter of the amount of electric power communicates with the guest. It is considered that there is a time limit in the provision of time information to the electric power meter. Namely, when it is assumed that it takes a second to transfer the weather information to a family, it takes an hour to transfer the weather information to 3,600 families. A real-time clock is loaded in the electric power meter and differential loads are applied according to the times. The clock time is corrected and verified periodically at all times. The abnormal use of electrical power is checked periodically or digital sealing is used for a case in which the derivation or intrusion is performed by intruding the modem of the power line to a PC. The digital sealing is systematically carried out through the composition of the computer hardware (software) and the hardware (hardware). The digital seal for periodic verification of the abnormal use of electrical energy is performed by a method in which the terminal transmits details of the amount of energy used at a point of time, for 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 that will be transmitted at the next time point, and compares the result of the comparison with the total amount of electrical energy used for the same period. When a voltage is applied to an output terminal in the state where a relay or engaging relay cuts off electrical power, it is determined to be a surreptitious use of electricity. As a result, emergency information is transmitted to the server. The total details of the use of the electric power of the server can be used as a basis for the realization of an agreement or agreement on prices, advantageous for a contract, by applying a reserve ratio during the purchase of electric power , by estimating the use of electricity for a period of days, months, or seasons based on the total amount of electrical energy used for a period of hours, days, months, or seasons. When a circuit breaker interrupts the supply of electrical energy because the stored credit value becomes depleted, an interruption due to overcurrent, an interruption in a special case, or the use of electrical energy by derivation of a source of energy from the front end of the meter, the abnormal use of energy electrical, is detected by a method of verification of the presence of a charging voltage. The credit value is transmitted and stored in the electric energy meter, the gas meter, the water meter, and the calorimeter via the modem of the ejiergy line. The credit value of the electric power is stored in the? VM and the remaining values are stored in the respective regions of the electronic bag of the IC card. Hereinafter, the structure and operation of the electric power meter, elaborated considering the previous points, will be described in more detail with reference to Figures 5 to 7. Figure 5 shows the electric energy meter that transmits and stores the information of the values through the modem of the electric power line. In Figure 5, a latching relay 1 is a relay switch of the on / off latch type to interrupt the supply of electrical power. A shunt resistor 2 measures an alternating current (AC) by a manganese resistance (Mn) of 0.1 O. When the latching relay 1 is interrupted, a sensor 3 Energy consumption detects normal use when the sensor output is "0" and when terminals ls and ÍL are diverted and electrical power is surreptitiously used when the sensor output is "1". A buzzer 4 requests a new credit value password to the SVM after the balance of a password exchanger 10 is consumed, and generates an audible alarm, thereby guiding the transmission and storage of the credit value by a user of the electric power. An IC card 5 of credit value / added value storage records the serial number of the card (C? N) of a subscriber's IC card in a management database by the master key of the energy reseller. electric that handles the electric power meter storage of credit securities according to the present invention, and verify the presence of a legal, registered CSN, when the server is asked to transmit the credit value, thus preventing the illegal use of electric power. A voltage divider 6 adjusts the AC voltages of 117, 220 and 24TV to be within the input voltage range of an analog-to-digital voltage converter (V-ADC). The interval The voltage is selected by the ratio of the two resistors that are connected in series. A V-ADC 7 is a circuit to convert an AC voltage analog signal to a 16 bit digital signal. An analog-to-digital current converter (I-ADC) 8 is a circuit for converting an AC current signal flowing through the shunt resistor 2 into a 16 or 20 bit digital signal. An electrical energy consumption operation circuit 9 calculates the electrical energy (Watts) by multiplying the digital signal of the V-ADC 7 by the digital signal of the I-ADC 8, and converts the result of the multiplication into a number of pulses. and in width signal. The electric power consumption operation circuit 9 compares the phase of the voltage with the phase of the current, calculates an angle by which the two phases are different, and outputs a phase difference as a signal, applying in this way Differential loads to the things that temporarily use the induction load. The password exchanger 10 reduces the passwords according to the amount (Watt / hour) of the electrical energy consumed per unit of time, requests new passwords from a passwords tank of units when the passwords inside the exchanger 10 of passwords are consumed, and reduces the new passwords according to the amount of energy consumption. If the password pool of 10 units is consumed, passwords of 100 units are required for the SVM that will be described later and the password pool of 10 units is again filled. The passwords required for the SVM 166 can be received through the authentication process of the SAM 164. A table 11 of power consumption and RTC performs a differential operation of electric charges of multiple steps according to a power supply and a demand situation of 50%, 75%, 100%, 150% and 200% based on a real time clock comprised of years, months, days, hours, minutes and seconds (YYMMDDHHMMSS). An IC card reader and a recorder 12 conforming to ISO 7816 is a communication port comprised of eight terminals defined by ISO 7816 Part 2, including Vcc, Cik, DIO, Readjust, and Gnd to communicate synchronously and asynchronously with the IC card. Multi-purpose credit values for things such as electric power, Gas, water, hot water, thermal energy, and pay-per-view TV are recorded on an IC card by inserting an IC card normally issued in the electric power meter in an online / offline state. After recording the value transmitted from the gas service server through the value transmission and the electric storage energy meter on the IC card, the IC card is removed, inserted into the gas meter and the value information it is transmitted to the gas meter, thereby reducing the value information on the card according to the amount of gas usage. Accordingly, the electric power meter for transmission and storage of values can be prepared in an offline state. A modem 13 of the power line performs data communication through the power line. Each modem is set by one of 256 ID addresses of the power line modem (PLMID). An AC / DC power source 14 supplies an operating voltage required by the electric storage energy meter according to the present invention. The 3-byte ID which is an intrinsic number of the electric energy storage meter is recorded in a ROM during production. A non-volatile memory 15 comprised of an instantaneous memory registers a situation of electric power consumption during a certain period, for example, the details of the electric power consumption per 24 hours are found by recording the amount of electric power consumption of the Electric energy storage meter as 16 bits information every 60 seconds, the details of the electric power consumption for a week by adding seven total amounts of the daily electric energy consumption together, and the details of the monthly electric power consumption by the addition of thirty total amounts of the daily electric power consumption one to the another, periodically verifies the surreptitious use of electrical energy or the abnormal consumption of electrical energy from a remote distance, and performs electronic sealing. A revolving collective bar 16 includes a central processing unit (CPU), 162, a secure access module (SAM) 164 for maintaining a coding key and a coding algorithm for storing the value Credit, and a storage value module (SVM) 166 to store the credit value, prevents the manufacture and use of credit value information, and intrusion, and excludes a cryptographic attack. A LCD 17 liquid crystal display visually shows the balance of the credit value, a transmission status, a real-time electric power consumption situation, and a cumulative electric power consumption situation, to be visually distinguished by a user. A power line input and output terminal 18 is comprised of ls, 2s, 2L and ÍL to connect the input and output lines of the electrical energy to one another, and a cover or cover to prevent physical derivation. A lightning conductor 19 is a circuit to absorb lightning or a transient overvoltage. An electric power meter for measuring electrical energy of a particular type was described above. However, the electric power meter according to the present invention can measure the electrical energy of at least two types, by including the voltage divider 6, the V-ADC 7, the I-ADC 8, the latching relay 1 , Y the derivative resistor 2 according to the type of electrical energy. Namely, when the voltage divider, the V-ADC, the I-ADC, the engaging relay, and the shunt resistor are combined so that at least two types of power sources with different voltages can be selectively or simultaneously used, the respective amounts of the current are additionally measured and operated. The operation of the electric storage energy meter having the above structure is described as follows. As mentioned by the electric power supplier or the electric power reseller, the guest's credit value is stored in the SVM 166 of each terminal through modem 13 of the power line using the value storage method credit, each electric power meter calculates the charge according to the amount of electric power consumption operated by the electric power consumption operation circuit 9, compares the calculated charge with the balance of the credit value information stored in the the SVM 166, and calculate the charge through the password exchanger 10. When a balance of no more than a certain amount is left in the SVM 166, the user is informed of the status of the balance by issuing a buzz. When the balance is insufficient, the credit value is transmitted from the guest to the SVM 166 by the aforementioned credit value storage method, or the power supply is interrupted by the operation of the interlocking relay 1. The value information Credit can be stored in the SVM 166 by communication between the guest and the terminal in the electric energy storage meter according to the present invention. However, it is possible to transmit the information of the value of the electric energy stored in the IC card 5 to the SVM and store the information transmitted in the SVM by inserting the IC card 5 electric, gas, water and calorie for a family or an establishment to which a certain amount of money legally issued is recorded to the electric energy storage meter, according to the present invention. That is, the electric power meter according to the present invention shows the information such as the amount of monthly consumption • and the balance of the card in the LCD 17 installed in it by using a certain amount of electric power in a range of values recorded in the? VM, and sounds the buzzer 4 when the balance of not more than a certain amount is left on the card. As a result, the user asks the server to transfer the credit value. The value of the credit is automatically charged to an account of a bank previously contracted or established by a credit card. The value of the electrical energy is received online through a power line and stored in the SVM 166. The value is reduced according to a scale of energy use. In consecuense, the electric power supplier and the electric power reseller can save costs by omitting the reading processes of a meter, entering signals and calculating the amount of use, and printing and sending an invoice or receipt. A receipt for electric power is paid in advance. As a result, a process of recharging overdue debts is omitted. Also, it is possible to decrease the receipt or invoice for electric power due to the benefits of the prepaid interest, applications of Differential charges according to the time of use of electric power, and the cost saved in the difference between a purchase price of electric power and a sale price of electric power. The electric power seller can manage a business with high added value. In order to prevent the use of a manufactured card different from an IC card legally issued by the electric power supplier or the electric power reseller, the SAM 164 to authenticate the card is loaded into the electric power meter. When the card is inserted into the terminal, the terminal and the card authenticate each other. When the amount of the money information on the card is transferred by the terminal as the credit value, the terminal operates according to the coding process shown in Figure 1. Accordingly, the use of the manufactured card is prevented. A method of volatilization of an encoded key, which disables the terminal, during the dismantling of the meter, can be considered against an intruder's cryptographic attack, for example, the dismantling of the electric energy storage meter. values in order to manufacture by the terminal or the card. However, the coding algorithm and the encoded key within the terminal have only a quantity reduction key in which the credit value information is reduced according to the amount of energy consumption. As a result, it is not possible to increase the money or information of the credit value. In particular, in the present invention, when a user / subscriber makes contact with an ARS server through a telephone or a digital intercom in order to require a transfer of the credit value, the amount of use is selectively established using the credit card or the bank account. The process of transferring securities begins within an interval in which payment is guaranteed. The process can also be done through the Internet. In particular, it is possible to automatically transfer the value when the value stored by the automatic transfer of account contract between the seller of the electric power / the reseller of the electric power and a financial institution, is reduced to a certain scale, and for persons who have never used a computer or network information communication. In particular, in the case of making a payment request transaction for an electronic transaction process SET with a direct payment card, the server that operates as a cyber market can put commercial details in a digital envelope (DE), which has the effect of signing the business details. Consequently, the commercial process can not be denied or manufactured. The embodiment process and the aforementioned condition of the present invention will be described in detail hereinafter. 1) Processes of generation, transfer and storage of credit value The credit value information is generated through communication and operation with the subscriber's management database using the master key (Mk) of the electric power seller or the electric power reseller. The subscriber ID number that is required by a LAN modem of the power line is selected through the area service and supervision (AS) and the local service and supervision (LS). When the request for The subscriber ID number and the communication are completed, the legality of the server and the terminal is authenticated by the aforementioned authentication process. When authentication is complete, the required credit value information is transferred. The credit value information transmitted through the power line is stored in the storage value module (SVM). 2) Processes for transfer and storage of added value The efficiency of the present invention is increased by the addition of a value-added transfer function that can be used in connection with energy, gas, water, calorie, and hot water meters, operating off-line through the IC card without a separate communication line. The generation and transfer of added value are carried out through the aforementioned processes of generation and transfer of value. The added value is stored in the IC card instead of in the electric power meter. Information Value-added for things such as gas, water, hot water, and thermal energy, stored in the IC card can be operated, inserted inside the water and gas meters off-line, IC card that are compatible with the IC card provided in Korean Patent Applications Nos. 98-6947 and 98-6948 filed by the same applicant. As a result, the efficiency of management is maximized. 3) Consumption of credit value information The credit value information stored in the SVM 166 is reduced in a password exchanger (TE) 10 according to the amount of energy consumption. The password is reduced per unit of time by several milliVatts, several watts, or several kilowatts. When the password for a minimum unit is exhausted, the credit value information is reduced by a process for requesting a new password. 4) Differential application of the energy consumption ratio A mode of electric power use that can differentially apply multiple steps of electric power usage proportions, according to the time zones of the days of the week and the weekends, seasons and months in which the amount of the value Credit used is selected by a program and applied automatically. In table 11 of electric power consumption mode, different proportions or speeds can be differentially applied, according to the time zones and the characteristics of the supply and demand of electric power and the supply of electric power and the use of electric power. the same, for example, 100% in daylight hours of the days of the week, a discount of 75% before and after the daily working hours of the days of the week, a discount of 50% at midnight, a premium or 200% bonus in daily business hours, and a bonus or prize of 300% from 2 to 4 pm in the summer during which the use of air conditioners increases rapidly, is applied by a real time clock (RTC). Since the separated TE 10 is applied with respect to the same amount of electric power usage, the stored credit value is differentially applied. As a result, the electric power consumption becomes optimal during each time zone. In this way, the efficiency of supply and demand of electric power is maximized. Therefore, the electricity bill or receipt is reduced.

) Verification of balance and automatic interruption The credit value information of the SVM 166 is displayed visually on a display device such as a liquid crystal display so that a user can verify the balance at any time. When the credit value is exhausted, the password exchanger informs the user that the latest passwords are being used by polling an alarm of an audible frequency. When the credit value is not recharged before the last password is consumed, the supply of the electric power is interrupted by sending a signal of interruption to the coupling relay connected in series to the power line. In order to satisfy the various processes and conditions of embodiment mentioned above, the present invention can be used in connection with the various gas and water meters where it is possible to transfer the value added by the IC card based on the energy meter electric value transfer and stock storage with which it is not necessary to read a meter based on the following structures and principles. The electric energy storage meter according to the present invention measures a voltage (V) and a current (A) in real time, calculates the amount of electrical energy () using the electric power consumption circuit, measures the consumption of electric power per unit of time, converts the stored value information into a password, reduces the password according to the amount of consumption of electric power per unit of time in a password exchanger 10, and requests new information of the credit value when the password has been exhausted. Also, all the Information that the user must know such as the amount of the remaining credit value information and a status of the energy consumption, is displayed visually through a liquid crystal display 17. When the last information of the credit value is converted to the password form, the user is informed by the sound of an alarm that has an audible frequency. As a result, the credit value is recharged. When the internal information of the credit value is exhausted, the supply of electrical energy is interrupted by the interruption of the coupling relay 1. In the mode table (MT) 11 through which it is possible to differentially apply the proportion of electrical energy by minus five steps, the real-time clock (RTC) differentially applies the proportions of electrical energy of various steps such as 50%, 75%, 100%, 200% and 300% according to the time zone and reduces the information of the credit value. Namely, although the same electric power is used per unit of time, the credit value of the SVM is differentially reduced since the TE 10 applies multiple steps of proportions of electric power for a defined time program in the MT credit. As a result, the electric power consumption becomes optimal during each time zone. Therefore, the supply and demand of electric power are well balanced. A discount benefit according to the selective use by the user is given by the multi-step electric power rate system. For example, a discount for night hours in which the supply of electrical power is excessive can decrease the reserve proportion of energy supply of the energy provider. When offices use intensely air conditioners in the summer, a discount energy tariff is charged and a heat storage system is induced. Consequently, it is possible to give a discount benefit to the consumer of electric power such as a home or an establishment. The electric storage energy meter according to the present invention has a collective bar structure of scrambled data in which a CPU 162 and an internal memory can not be read by an impaired person in order to prevent the value Stored manufactured and cryptographically attacked. The electric storage value meter is comprised of the secure access module (SAM) 164 within which the secret intrinsic key (KT [n]) and the encryption algorithm, and the storage value module ( SVM) 166. If the intruder or the coding attacker dismantles the electric power meter in order to manufacture the credit value information, the encoded key and the encrypted algorithm of the SAM and the SVM can not be observed. The SAM, the SVM and the master key (Mk) of a host computer are mutually authenticated. In this way, the SAM and the SVM can transfer and store the credit value information through the aforementioned processes using the master key. The? AM and the SVM can store the credit value information and the value added information on the IC card using the master key. When the IC card is inserted in the electric power meter, a response is received to readjust (ATR) the signal, by sending a readjust signal to the card, the IC card and the terminal were mutually authenticated, the Credit value information is exchanged through the SVM and the SAM, and the credit value information is calculated with respect to the legal use of the IC card. The credit value information is recorded by a separately coded key (Mk) of a shipper. Therefore, it is not possible to increase the credit value. Such processes are performed in compliance with the international standards organization (ISO) 7816 Part 1, Part 2, Part 3, Part 4, Part 8 and Part 10 and contain a physical standard, an electrical signal, a communications protocol, and a coding process. At least two coded keys are stored according to the request of the handler. A coded key is updated by a distance of a certain time. The encoded key is selectively used. Consequently, the fraudulent use of the credit value is prevented. The transfer of the credit value and the added value and the periodic verification of the legal use of the value are carried out through an electric power modem. A power consumption sensor circuit is provided and the energy usage information is recorded in a non-volatile memory (NVM) 15 in order to periodically verify the surreptitious use of electric power and punish illegal use without having to visit a site in which an electric power meter is installed and the guide seal or tartar is verified. Such a circuit can be periodically verified by the LS and the AS, thus performing an electronic sealing function without verifying the sealing of the physical guide. The electric energy storage meter has a serial number of electrical energy meter and storage of values (? VPMSN) of 3 bytes. The modem 13 of electrical power communicates with the LS by means of an address of the modem identification number (M-ID) of 1/256. When the server of the electric power seller or the electric power reseller observes a request to transfer the value, it initiates a short distance communication with the electric meter of storage of the subscriber's securities, according to a process of directing to select the subscriber's M-ID. The subscriber requests the transfer of the credit value by contacting the ARS of the electric power vendor or the electric power reseller by telephone or a digital method 20 and a keypad 21, selecting the establishment by credit card or bank account, and selecting the payment of the credit value of the electric power transferred. Then, a credit value management server is required to transfer the credit value for the AN given by the server of a credit card company. The credit value management server of the electric power seller calls the M-ID through the AS and the LS, transfers the credit value to the SVPM and stores the transferred credit value by performing the stock storage processes previously mentioned . The LS sequentially monitors the status of the energy consumption of up to 256 subscribers of electric energy storage values, through the modem of electrical energy connected to the electric power line 117V / 220V at a maximum distance of 3 km. The LS sequentially calls the address SVPMs 1/256 ... n / 256, verifies and re-checks the internal real-time clock status of the SVPM, controls a system mode of speed, checks the CSN of the card, supports the balance of the credit value, verifies the presence of surreptitious and abnormal use of electric power, and downloads the reports on the electric power consumption during the days, weeks or months, totaling this mode and estimating the demand for electric power. The results of the totalization and the estimation are used as guides to negotiate the purchase price of the electric power and the re-control of the price of electricity supply. In credit transfer and storage, gas, water, heat and hot water meters other than the electric power meter consist of a meter that operates off-line through the use of an IC card, without a separate communication line, since these installation environments are inferior and an online construction is very complicated. When the value-added information transferred through the electric energy storage meter, is stored in the IC card and the IC card is inserted in the water, gas and heat meters, the value added information is stored in each meter. Passwords are reduced by means of same process of reducing the value of credit. When the credit value information is exhausted, a valve is closed to stop the supply of gas, water, heat, and hot water. The efficiency of the present invention is increased with the value-added transfer function in which it is possible to use the electric energy transfer and storage value meter together with the value-added service. The added value is generated and transferred through the same processes of generation and transfer of the credit value. The added value is stored in the IC card instead of in the electric power meter. Value-added information for things such as gas, water, hot water, and heat, is stored in the IC card, by performing the above processes, and can be transferred to the water and gas meters, off-line, of the IC card, which can maintain the IC card provided in Korean Patent Applications Nos. 98-69 7 and 98-6948. From now on, the petition and the processes of transfer of credit values in the electric power modem, will be described with reference to Figure 6. A subscriber IC card 52 is issued to those who wish to receive the IC card, by using a master key IC card 51 of the system manager in a 50 electric power reseller. After establishing the credit value for things such as electricity, gas, water, hot water, and thermal energy in cash or by credit card immediately, a first credit value is stored in the IC card. The credit value of electric power on the card is stored in the electric power meter by inserting the IC card into the electric storage value meter of a user 55. When the IC card is inserted into the the gas, water, hot water and electric energy meters of the user 55, the credit value is stored in each meter. After the first storage of the credit value, the • subsequent storage of the credit value / added value is performed by the value transfer process using the electric power modem. The transfer and Storage of securities can be done using the telephone, the Internet, a P-ATM (EMV '96), and the electric energy storage meter. The processes of transfer and storage of the value are performed with the formation of the aforementioned coding algorithm. The credit value / value added transfer channel is as follows. The registration information of the subscriber is taken from the subscriber database of the host server of the electric power dealer 50. Payment to a bank or to a VAN company is guaranteed, by a user who selects one between a credit card number, a direct payment card number, and a bank account number. The credit value information is encoded by the master key of the? AM. The ID of the subscriber's electric energy storage meter is required through the AS and LS networks. The SAM and the master key are mutually authenticated. Then, the credit value / added value information is transferred. The Local Supervision Unit (LS) down-loads the electric power usage record for a period of hours, days, weeks, or months from the electric meter of stock storage, periodically check the status of the use of electric power and the balance of the credit value on a per hour or daily basis, readjust to time, load down the mode of use of the electric power and the program, and periodically checks for surreptitious and abnormal use of electrical energy. Also, the amount of money calculation is made between an amount of the money calculation system 5 of a seller 53 of electric power and the reseller 50 of electric power by a method similar to the aforementioned processes. Figure 7 is an exploded perspective view showing the external shape of the electric storage energy meter according to the present invention. The electric storage energy meter according to the present invention includes an LCD screen 17 on the upper portion of a front surface and an input and output terminal 66 on the lower portion of the front surface. The input and output terminal 66 is connected to the electric power line for the introduction and extraction of electrical energy, and it is covered with a cover 64 for the prevention of surreptitious use. A digital intercom 20 and a value transfer request key 21 are provided on the upper surface of the cover 64 for prevention of surreptitious use. Also, a slot 60 for the insertion of the IC card into which the IC card is inserted., is formed on one side of the electric power meter. The credit value is stored in the IC card and read from the IC card when it is inside the IC card insertion slot 60. Also, a sealing unit 62 for surreptitious use / dismantling verification, to seal the electric power meter so that electric power can not be surreptitiously used, is part of the electric power meter. As described above, the present invention has been described only with respect to the electrical energy meter for storage of values via the power line modem. The necessary mutual information can be exchanged via modem communication of the electric power line between the server and the terminal. A general telephone line, a line radio frequency relay communication, and a cable TV line can be used instead of the electric power line. As mentioned above, according to the present invention, it is possible to reduce the expenses of visiting personnel by omitting the meter reading process for things such as electric power, gas, water and thermal energy, processing costs by computer, the printing and sending of receipts or invoices, and the invoice for shipping costs. Also, it is possible to reduce the loss due to uncollected electricity bills and to the overdue debts, to give the added value since the credit value is paid in advance by a credit card or a bank account. Consequently, an electric power supplier can give a high added value.

Possibility of Industrial Application The present invention describes a meter of electrical energy, compound, with which it is possible to solve the economic and security problems of having to visit and examine visually a remote, conventional electrical energy meter.

It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
