Description
Technical field
The present invention relates to public charging pile and charging method, be specifically related to a kind of encryption public charging pile of card-scanning type and charging method.
Background technology
Original charging pile generally individual uses or internal institution uses, and the unified clearing electricity charge, in public parking stalls such as Public Parkings
Charging cannot carry out reasonable fee for individual.Existing implementation, uses card not have encryption function, the safety of payment
Property cannot ensure, background system cannot guarantee the verity of Transaction Information.There is no rational charge method, traditional contact M1
The not encryption of card (logic storage card) or rfid card sheet (radio frequency memory card), background system does not has encrypted authentication to transaction data.
Substantially DIP or SOP of ESAM (Embedded Secure Access Module) embedded safe control module
The CPU card chip of chip package；
PSAM (Purchase Secure Access Module): point of sales terminal secure access module.
Summary of the invention
For solving the deficiency that prior art exists, the invention discloses a kind of ciphering type and swipe the card public charging pile and charging method, this
Invention uses CPU card, and ESAM key, the mode of PSAM encryption equipment, CPU card, ESAM chip, in PSAM chip
Key all calculates according to the encryption factor through same Zhang Jiami master card, and three parts differ with group key but can verify the other side,
Transaction to everyone has the complex verification of CPU card and charging pile ESAM cipher key interaction, makes individual pay and has safety,
Card cannot be copied, and uploads background information and encrypts through charging pile ESAM key, can be concluded the business by PSAM encryption equipment identification in backstage
The verity of information, it is to avoid utilize data to steal and brush other people card.The ciphering type of the present invention is swiped the card public charging pile and charging method.
Mainly solving public charging pile payment card safety, precise control of charging, background monitoring data are authentic and valid.
For achieving the above object, the concrete scheme of the present invention is as follows:
A kind of encryption public charging pile of card-scanning type, including panel, described panel and digital electric meter, CPU card card reader, aobvious
Display screen, touch keyboard, charging socket control module, network communication device and electric automobile charging station system communication；
Panel is led to the background monitoring system of encrypted test mode with electric automobile charging station system by charging pile ESAM key
Letter, background monitoring system is remotely called real time data, the situation of monitoring charging pile, is indicated according to the display of display screen and swipe the card
Charging operations, during swiping the card, panel is by close with Payment Card of the key in the CPU card card reader of band ESAM cipher key module
Key is checked, and continues operation after verification is consistent.
Described digital electric meter and network communication device are communicated with panel by RS485 interface.
Described panel is also connected with display lamp, described display screen, touch keyboard, charging socket control module and display lamp and control
Making sheet is connected by general I/O interface.
Described CPU card card reader is communicated with panel by RS232 interface.
Described panel is by Ethernet or the communication mode of GPRS and charging system for electric automobile communication.
Described network communication device is GPRS/WCDMA/TD-LTE/FDD-LTE communication module.
A kind of charging method encrypting the public charging pile of card-scanning type, comprises the following steps:
Step one: user indicates, according to the display of display screen, the charging operations that carries out swiping the card, and during swiping the card, the payment cipher of input leads to
Carrying out data interaction with CPU Payment Card after crossing the encryption of the ESAM cipher key module in CPU card card reader, CPU Payment Card passes through Ka Neimi
Checking payment cipher after key deciphering, verification unanimously can continue to operation；
Step 2: select different charging modes to be charged on a display screen, charging modes includes automatically being full of, fixes time,
Deposit volume, determine electricity, selected after swipe the card and start to charge up, card reader is charged the amount of money and withholds and ash lock, control CPU Payment Card
Making sheet is started charging after being pinned on charging inlet by the charging wire of user by the lockable mechanism in charging socket control module and opens
Close；Avoiding unexpected plug charging gun in charging process to cause contingency, user does not settles accounts and cannot be driven away by electric automobile yet simultaneously,
Ensure that the interests of charging pile operator；The purpose of ash lock is that ash lock clamp piece cannot operate at other charging piles, it is to avoid a card
Fill more and cause the amount of money to overdraw.
Step 3: panel by digital electric meter read in real time the point that institute's power consumption arranges according to charging pile, peak, put down, paddy electricity price
Calculate the amount of money used, be automatically stopped charging when meeting set condition, when not met condition thinks complete charge process, then
Secondary swiping the card can stop charging；
Step 4: swipe the card checkout time, panel charge information is sent to CPU card reader and by ESAM key encrypt after and
CPU Payment Card carries out checkout operation；
Step 5: after Transaction Information is again encrypted by charging pile by the ESAM cipher key module in CPU card reader, is led to by network
T unit is sent to background monitoring system, and background monitoring system is decrypted by PSAM encryption equipment, and checking GMAC information is led to
Later, this charging details are preserved.Avoid Noncoded Information to be cracked the robber's brush problem caused.
In step 3, impose a condition for: be automatically full of, fix time, determine electricity or deposit volume.
In step 4, the information of charging includes: payment card information, charge capacity, the amount of money and charging pile information.
In step 4, detailed process when settling accounts of swiping the card is: CPU card is to adding after confidential information is deciphered and is verified at stored value card
Middle deduction spending amount, and recover from ash lock status, transaction encryption information GMAC is i.e. monitored backstage for identifying transaction simultaneously
The encrypted message of uniqueness passes to charging pile panel, and charge switch is first disconnected by panel, then controls mould by charging socket
The charging wire of user is decontroled by block, and operation interface prompt user does not forget Payment Card and extracts charge cable, man-machine interaction of charging
Process completes.
In step 5, Transaction Information includes that charge information and GMAC etc. add confidential information.
Panel decontrols the charging wire of user specifically by charging socket control module: panel CPU controls mould to charging socket
Block lockable mechanism transmitting order to lower levels opens the electromagnetic lock being stuck on charging gun head.
Beneficial effects of the present invention:
CPU card key, ESAM key in charging pile, the background system PSAM encryption equipment key Trinity.It is right to identify mutually
The verity of side, charging transaction can carry out secure payment by swiping the card, and background system can monitor charging pile state in real time, to transaction
Data carry out security identification and ensure data validity, improve the fund security in card.
The mode of swiping the card uses CPU card to add ESAM and stores key, and charging pile is encrypted knowledge by internal ESAM double secret key CPU card
Not with checking, increase fund security in card, also ensure that public charging pile is not imitated card and usurps.
Backstage is transmitted transaction data and is used ESAM encryption, PSAM manner of decryption, it is ensured that fund security by charging pile, it is to avoid report
Literary composition is intercepted the risk usurped.
