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 is generally private use or internal institution use, and the unified clearing electricity charge, cannot carry out reasonable fee for individual in public parking stall chargings such as Public Parkings.Existing implementation, use card not have encryption function, the security of payment cannot ensure, background system cannot guarantee the authenticity of Transaction Information.Do not have rational charge method, the not encryption of traditional contact M1 card (logical storage card) or rfid card sheet (radio frequency memory card), background system does not have encrypted authentication to transaction data.
The essence of ESAM (Embedded Secure Access Module) embedded safe control module is the CPU card chip of DIP or SOP 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 to swipe the card public charging pile and charging method, the present invention adopts CPU card, ESAM key, the mode of PSAM encryption equipment, CPU card, ESAM chip, key in PSAM chip all calculates according to the encryption factor through same Zhang Jiami master card, three parts are not identical but can verify the other side with group key, everyone transaction is had to the complex verification of CPU card and charging pile ESAM cipher key interaction, individual is paid there is security, card cannot be copied, upload background information through charging pile ESAM secret key encryption, backstage is by the authenticity of PSAM encryption equipment identification Transaction Information, avoid utilizing data to steal and brush other people card.Ciphering type of the present invention is swiped the card public charging pile and charging method.Mainly solve public charging pile payment card safety, charging precise control, background monitoring data are authentic and valid.
For achieving the above object, concrete scheme of the present invention is as follows:
The public charging pile of a kind of encryption card-scanning type, comprise control panel, described control panel communicates with digital electric meter, CPU card card reader, display screen, touch keyboard, charging socket control module, network communication device and electric automobile charging station system;
Control panel is communicated with the background monitoring system of electric automobile charging station system with encrypted test mode by charging pile ESAM key, the long-range calling real time data of background monitoring system, the situation of monitoring charging pile, display instruction according to display screen carries out swiping the card charging operations, in process of swiping the card, control panel is checked by the key in the CPU card card reader of band ESAM key module and the key in Payment Card, checks unanimously and continues operation.
Described digital electric meter and network communication device are communicated with control panel by RS485 interface.

Encrypt a charging method for the public charging pile of card-scanning type, comprise the following steps:
Step one: user carries out swiping the card charging operations according to the display instruction of display screen, the payment cipher inputted in process of swiping the card is encrypted afterwards by the ESAM key module in CPU card card reader and CPU Payment Card carries out data interaction, CPU Payment Card, by checking payment cipher after secret key decryption in card, is checked and unanimously can be continued operation;
Step 2: select different charging modes to charge on a display screen, charging modes comprises and is automatically full of, fixes time, deposit volume, determines electricity, swipe the card after selected and start charging, card reader is carried out the charging amount of money to CPU Payment Card and is withheld and to lock with ash, and the charging wire of user to be pinned after on charging inlet by the lockable mechanism in charging socket control module and starts charge switch by control panel; Avoid unexpected plug charging gun in charging process to cause mishap, user does not settle accounts and electric automobile cannot be driven away yet simultaneously, ensure that the interests of charging pile operator; The object of ash lock is that grey lock clamp piece cannot operate at other charging piles, avoids a card multi-charging and causes the amount of money to overdraw.
Step 3: control panel reads by digital electric meter point that institute's power consumption arranges according to charging pile in real time, peak, flat, paddy electricity price calculate the amount of money used, automatically charging is stopped when meeting set condition, do not satisfy condition when thinking complete charge process, again swipe the card and can stop charging;
Step 4: swipe the card checkout time, charge information is sent to CPU card reader and by carrying out checkout operation with CPU Payment Card after ESAM secret key encryption by control panel;
Step 5: after Transaction Information is encrypted by the ESAM key module in CPU card reader by charging pile again, background monitoring system is sent to by network communication device, background monitoring system is decrypted by PSAM encryption equipment, after checking GMAC information is passed through, preserves this charging details.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 comprises: payment card information, charge capacity, the amount of money and charging pile information.
In step 4, swipe the card checkout time detailed process be: CPU card is deciphered enciphered message and in stored value card, is deducted spending amount after being verified, and recover from grey lock status, namely transaction encryption information GMAC is monitored backstage to be used for identifying that the encrypted message of transaction uniqueness passes to charging pile control panel simultaneously, charge switch first disconnects by control panel, then by charging socket control module, the charging wire of user is decontroled, operation interface prompting user does not forget Payment Card and extracts charge cable, and charging interactive process completes.
In step 5, Transaction Information comprises the enciphered message such as charge information and GMAC.
Control panel decontrols the charging wire of user specifically by charging socket control module: control panel CPU opens to charging socket control module lockable mechanism transmitting order to lower levels the electromagnetic lock be stuck on charging gun head.
Beneficial effect of the present invention:
CPU card key, ESAM key in charging pile, the background system PSAM encryption equipment key trinity.Can identify mutually the authenticity of the other side, charging transaction carries out secure payment by swiping the card, background system energy Real-Time Monitoring charging pile state, carries out safety and identifies guarantee data validity, improve the fund security in card to transaction data.
The mode of swiping the card adopts CPU card to add ESAM storage key, and charging pile is encrypted identification and verification by inner ESAM double secret key CPU card, increases fund security in card, also ensures that public charging pile is not imitated card and usurps.
Charging pile transmits transaction data to backstage and adopts ESAM encryption, and PSAM manner of decryption, ensure that fund security, avoids message and is intercepted the risk usurped.
