Preferably, said embedded-type security control module is the CEPESAM chip.
Microprocessor: be the core of whole intelligent electric energy meter, accomplish data acquisition, data storage, data operation, communication, control signal output, demonstration, corresponding event record etc.
Embedded-type security control module: be used for the message exchange safety certification.Through solid state medium or virtual medium to expense control intelligent electric energy meter carry out the parameter setting, the electricity charge that prestore, information return and write and when issuing remote control command; Need to carry out safety certification through the embedded-type security control module; Data encrypting and deciphering is handled, to guarantee safety of data transmission, confidentiality and integrality.When long-range electricity-selling system carried out data aggregation to expense control intelligent electric energy meter, the data that intelligent electric energy meter provides were also passed through the encryption of embedded-type security control module earlier.
Communication module: be used for transmitting with the long-range electricity-selling system information of carrying out.Communication module can comprise 485 communication modules, carrier communication module.
Metering module: be used for the metering of each related data of intelligent electric energy meter.
Data memory module: be used to store each related data of intelligent electric energy meter, prevent loss of data when the intelligent electric energy meter power down, this module can be encapsulated in microprocessor internal, also can be in the outside independent existence of microprocessor.
Relay: be used to cooperate the reclosing command of operating a switch, allow of long-range electricity-selling system to cut off the power supply, send electric control.
The setting of embedded-type security control module is closed a floodgate ammeter receiving remote electricity-selling system issues operate a switch, allow, and has passed through strict password authentification and safety certification earlier, rather than has directly been read by microprocessor.When long-range electricity-selling system carried out data aggregation to expense control intelligent electric energy meter, the data that intelligent electric energy meter provides were also passed through the encryption of embedded-type security control module earlier, rather than directly data transmit.The ammeter information teletransmission obtains the message exchange safety certification, has stopped network attack, has effectively prevented electricity filching behavior.
In single-phase long-range data management processes of taking the control intelligent electric energy meter, increase the data security verification process of ESAM, realize the end-end encryption mode of teledatas such as the amount of money and control command, solved the technical barrier of network attack; Employing should technology; Mainly be at the table end safety chip that meets the close SM1 algorithm of state to be installed, at local side the analysis protocol that meets the SM1 algorithm be installed, the data of network communication transmission course are enciphered data; The deciphering of enciphered data is not participated in MCU unit in the intelligent electric energy meter; Decrypting process is accomplished by the ESAM security module, according to performance, is carried out the operation of phase factor by the result in the MCU unit taking-up ESAM.
The advantage and the beneficial effect of the utility model are: a kind of intelligent electric energy meter with the embedded-type security control module is provided; Said intelligent electric energy meter can effectively guarantee the level security of ammeter information teletransmission; Stop network attack, effectively prevented electricity filching behavior.
