Technical field
The present invention relates to mutual electric energy meter of a kind of contactless information security and electric energy meter secure interactive system.
Background technology
The mutual electric energy meter of existing contactless information security; Generally form by master controller, metering circuit, storer, relay control unit, infrared interface, RS485 interface, keystroke interface etc.; This electric energy meter is present more advanced table, and this electric energy meter can constitute electric energy meter secure interactive system with electric power main website charge system and bank, can pass through power line carrier or wireless communication technology remote automatic meter reading by electric system; Realize remote automatic meter reading; User's inquiry of surfing the Net should be paid the electricity charge amount of money, and internet usage Web bank pays the fees, and perhaps the user should pay the electricity charge amount of money through message search; And use note to pay the fees, perhaps bank deducts fees in the day of withholing according to the agreement that withholds of user's signature in advance automatically.But this electric energy meter secure interactive system can't support carrier wave or the wireless mode of far copying at some applied environment, and the backstage electric system can't obtain customer consumption information, can't confirm the consistance of subscriber payment and actual amount receivable.Therefore this system's usable range is limited to.
Summary of the invention
The object of the present invention is to provide with a kind of good stability, the backstage electric system can accurately obtain the mutual electric energy meter of contactless information security and the electric energy meter secure interactive system of customer consumption information fast.
The mutual electric energy meter of this contactless information security provided by the invention; Comprise main control MCU; Also comprise NFC control module and NFC safe unit, the NFC control module has antenna and is used for and extraneous mobile communication with NFC communication function, passes through I between NFC control module and the main control MCU
2The C bus communication and is communicated by letter through the SWP single-wire-protocol between the NFC safe unit.
Ammeter secure interactive system with the mutual ammeter formation of the contactless information security of the present invention; Comprise electric power main website charge system, bank charge system, mobile phone, the mutual electric energy meter of contactless information security with NFC communication function; Bank charge system and electric power main website charge system are carried out network service; Said mobile phone and bank charge system carry out 3G with electric power main website charge system and communicate by letter, and carry out contactless bi-directional exchanges of information with the mutual electric energy meter of contactless information security.
Owing to be provided with NFC control module and NFC safe unit in the mutual electric energy meter of the contactless information security of the present invention; Mobile phone with NFC communication function can be communicated by letter with it; Mobile phone can be communicated by letter with the kilowatt meter charge system simultaneously; Therefore can make electric system obtain customer consumption information fast, overcome the problem of the existence of prior art, compared with prior art the present invention can bring following advantage:
(1) the mutual ammeter of contactless information security and have the safe, convenient of message exchange between the mobile phone of NFC communication function.Because the mutual electric energy meter of contactless information security is contactless communication mode (mobile phone with NFC communication function is hereinafter to be referred as the NFC mobile phone) with having between the mobile phone of NFC communication function, so use very convenient; Owing to all introduced the NFC safe unit in mutual electric energy meter of contactless information security and the NFC mobile phone, in the process of exchanges data, will carry out the operation of a series of encryption and decryption, signature and certifying signature in addition, so communication between the two is safe;
(2) information interactive process between mutual electric energy meter of contactless information security and the main website can guarantee information privacy, integrality and freshness.Native system can be supported the bidirectional information authentication between self and the main website.Through between mutual electric energy meter of contactless information security and electric power main website, sharing private cipher key; And to mutual information carry out encryption and decryption and signature operation; Can guarantee that institute's interactive information is not distorted between the two, thereby guarantee the privacy and the integrality of data.Through in interactive information, inserting the variable quantity relevant with the time, freshness that can guarantee information, thus prevent Replay Attack.Correspond to Utilities Electric Co. and pay the fees and use, more than three kinds of securities can prevent the malicious user eavesdropping, distort the amount of money or repeatedly use the same information of paying the fees to supplement with money of paying the fees;
(3) saved construction cost and the maintenance cost that Utilities Electric Co. is used for remote system; After using this electric energy meter and system; Utilities Electric Co. can save original remote system, accomplishes the work of checking meter, paying the fees and prestoring by the user, has saved the construction and the maintenance cost of remote system.Do not having under the pattern of remote system, Utilities Electric Co. adopts the pre-payment pattern to come the NFC electric energy meter is controlled;
(4) personnel that saved Utilities Electric Co. drop into, and original sales counter business personnel quantity will reduce significantly;
(5) realized that the electricity charge copy the integrated of the process of paying, made things convenient for the user.Native system is supported user mobile phone this locality remote payment pattern of checking meter, and the user can use the pre paid functionality of the NFC mobile phone completion electricity charge with " stay indoors ".
Description of drawings
Fig. 1 is the structural representation block diagram of the mutual electric energy meter of the contactless information security of the present invention.
Fig. 2 is an ammeter secure interactive system schematic of the present invention.
Embodiment
Fig. 1 has reflected the structure of the mutual electric energy meter of the contactless information security of the present invention; Can find out that from this figure the present invention still has main control MCU, power circuit, metering circuit, storer, relay control unit, infrared interface, RS485 interface, keystroke interface, liquid crystal display etc.; Also have NFC control module and NFC safe unit; The NFC control module has antenna; Be used for and extraneous NFC mobile communication, the NFC control module be responsible for controlling and NFC mobile phone, NFC safe unit and main control MCU between information interaction.The NFC safe unit is responsible for carrying out security-related algorithm, and output result of calculation is given the NFC control module.Communication mode between NFC control module and the main control MCU is I
