For achieving the above object, technical scheme of the present invention is a kind of intelligent electric energy meter with embedded safe control module of design, and the intelligent electric energy meter of described band embedded safe control module comprises microprocessor, embedded safe control module, communication module, metering module, data memory module, relay; Described microprocessor is connected with embedded safe control module, communication module, metering module, data memory module, relay respectively.
Preferably, described communication module comprises 485 communication modules.
Preferably, described communication module comprises carrier communication module.
Preferably, described embedded safe control module is CEPESAM chip.
Microprocessor: the core being whole intelligent electric energy meter, the storage of data acquisition, data, data operation, communication, control signal output, display, corresponding event record etc.
Embedded safe control module: for message exchange safety certification.By solid state medium or virtual medium, optimum configurations is carried out to expense control intelligent electric energy meter, the electricity charge that prestore, information is when returning and write and issue remote control command, safety certification need be carried out by embedded safe control module, data encrypting and deciphering process, to guarantee security that data transmit, confidentiality and integrality.When long-range electricity-selling system carries out Data Collection to expense control intelligent electric energy meter, the data that intelligent electric energy meter provides are also first through the encryption of embedded safe control module.
Communication module: for carrying out information transmission with long-range electricity-selling system.Communication module can comprise 485 communication modules, carrier communication module.
Metering module: for the metering of each related data of intelligent electric energy meter.
Data memory module: for storing each related data of intelligent electric energy meter, prevent the loss of data when intelligent electric energy meter power down, this module can be encapsulated in microprocessor internal, also can in the outside independent existence of microprocessor.
Relay: for coordinating the operating a switch of long-range electricity-selling system, allow reclosing command to carry out power-off, power transmission controls.
The setting of embedded safe control module, ammeter is received, and long-range electricity-selling system issues operates a switch, allow to close a floodgate, and first have passed strict password authentification and safety certification, instead of directly by microcomputer reads.When long-range electricity-selling system carries out Data Collection to expense control intelligent electric energy meter, the data that intelligent electric energy meter provides are also first through the encryption of embedded safe control module, instead of directly data transmission.Ammeter information teletransmission obtains message exchange safety certification, blocks network attack, effectively prevent electricity filching behavior.
In the data management processes of single-phase remote cost control intelligent electric energy meter, increase the data security verification process of ESAM, realize the end-end encryption mode of the teledata such as the amount of money and control command, solve the technical barrier of network attack; Adopt this technology, mainly at table end, the safety chip meeting the close SM1 algorithm of state is installed, the analysis protocol meeting SM1 algorithm is installed at local side, the data of network communication transmitting procedure are enciphered data, MCU unit in intelligent electric energy meter does not participate in the deciphering of enciphered data, decrypting process is completed by ESAM security module, and according to performance, the result of being taken out in ESAM by MCU unit performs the operation of phase factor.
Advantage of the present invention and beneficial effect are: provide a kind of intelligent electric energy meter with embedded safe control module, and described intelligent electric energy meter effectively can ensure the level security of ammeter information teletransmission, blocks network attack, effectively prevent electricity filching behavior.
