Description
Technical field
The present invention relates to a kind of intelligent electric energy meter, be specifically related to a kind of intelligent electric energy meter with embedded safe control module.
Background technology
Along with the widespread use of intelligent electric energy meter, realized the teletransmission of ammeter information.Remote meter reading solves Traditional Man the inefficient and uncertain of pattern of checking meter at all, avoids to greatest extent mistake.Long-distance Control makes intelligent electric energy meter cut off the power supply, to send electric control according to the reclosing command of operating a switch, allow of long-range electricity-selling system.But the level security that the intelligent electric energy meter information remote transmits becomes increasingly conspicuous.
Summary of the invention
The object of the present invention is to provide a kind of intelligent electric energy meter with embedded safe control module, described intelligent electric energy meter can effectively guarantee the level security of ammeter information teletransmission.
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 described intelligent electric energy meter with 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 the CEPESAM chip.
Microprocessor: be the core of whole intelligent electric energy meter, data acquisition, data storage, data operation, communication, control signal output, demonstration, corresponding event record etc.
Embedded safe control module: be used for the message exchange safety certification.By 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 by embedded safe control module, data encrypting and deciphering is processed, with security, confidentiality and the integrality of guaranteeing data transmission.When long-range electricity-selling system carried out Data Collection to expense control intelligent electric energy meter, the data that intelligent electric energy meter provides were also passed through first the encryption of embedded safe control module.
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 for each related data of storage 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 for cooperating 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 safe control module is closed a floodgate ammeter receiving remote electricity-selling system issues operate a switch, allow, and has passed through first strict password authentification and safety certification, rather than has directly been read by microprocessor.When long-range electricity-selling system carried out Data Collection to expense control intelligent electric energy meter, the data that intelligent electric energy meter provides were also passed through first the encryption of embedded safe control module, 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 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 of the teledatas such as the amount of money and control command-end encryption mode, solved the technical barrier of network attack; Adopt this technology, mainly be at the table end safety chip that meets the close SM1 algorithm of state to be installed, the analysis protocol that meets the SM1 algorithm is installed at local side, the data of network communication transmission course are enciphered data, MCU unit in the intelligent electric energy meter does not participate in the deciphering of enciphered data, decrypting process is finished 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.
Advantage of the present invention and beneficial effect are: a kind of intelligent electric energy meter with embedded safe control module is provided, and described intelligent electric energy meter can effectively guarantee the level security of ammeter information teletransmission, has stopped network attack, has effectively prevented electricity filching behavior.
