Problems solved by technology

[0002] STS standard transfer specification (Standard Transfer Specification, referred to as STS) is an important technology in the prepaid vending system, which defines the token format as 20 digits, 66Bit valid data, of which 2Bit is used to distinguish the recharge code, management code and test code , the recharge code and management code are transmitted in a single-string token encryption authentication method, the management code is limited to a string of tokens, and 66Bit can only be used for simple parameter settings, and with the promotion and application of TOU rates, electricity price And the update of the fee rate, and because there are too many uncontrollable factors in the transmission method of single-string token encryption and authentication, for example, the transmission method of single-string token encryption and authentication needs to provide the token user to enter by himself, if the user does not enter Or missing input will cause the electricity price not to be updated, affecting the normal deduction of the electricity price and causing confusion in the deduction of the electricity price

Embodiment 1

[0049] like figure 1 As shown, a method for recharging offline prepaid electricity includes the following steps: obtaining the first trigger transfer token, the big data transfer token and the recharge data transfer token on the electricity sales system, and performing the first trigger transfer token Decrypt to get the trigger flag information;

[0050] like image 3As shown, the 66-bit data of the STS standard for the management token includes the token type, token subtype, random number field, TID field, Register / Amount field, and CRC field, which correspond to the Class, SubClass, and RND, TID, Register / Amount and CRC, and Class occupies 2 bits, SubClass occupies 4 bits, RND occupies 4 bits, TID occupies 24 bits, Register / Amount occupies 24 bits, CRC occupies 16 bits, and CRC is Class, SubClass, RND, TID, Register CRC16 check value.

[0051] like figure 1 and Figure 4 As shown, according to the trigger flag information, screening the first trigger transfer token that...

Embodiment 2

[0065] An offline prepaid electricity recharge system, including a generation decryption module, a screening module, and an analysis and calculation module; the generation decryption module includes an acquisition module and a decryption module, and the acquisition module is used to obtain the first The trigger transfer token, the big data transfer token and the recharge data transfer token are also used to obtain the first plaintext data of the second trigger transfer token and the total number of strings that need to be transferred by the big data transfer token; the decryption module is used to Decrypt the first trigger transfer token to obtain the trigger flag information, which is used to decrypt the big data transfer token to obtain the second plaintext data of each string of big data transfer tokens, and is also used to recharge the data transfer token for Decrypt to obtain the third plaintext data.

[0066] Obtain the first trigger transmission token, big data transmis...

Embodiment 3

[0071] A computer-readable storage medium, where a computer program is stored in the computer-readable storage medium, and when the computer program is executed by a processor, any one of the above-mentioned off-line prepaid power recharging methods is executed.

[0072] More specific examples of computer-readable storage media may include, but are not limited to, electrical connections with one or more wire segments, portable computer diskettes, hard disks, random access memory (RAM), read-only memory (ROM), erasable Programmable read-only memory (EPROM or flash memory), optical fiber, portable compact disk read-only memory (CD-ROM), optical storage device, magnetic storage device, or any suitable combination of the above.

[0073]In the present application, a computer-readable storage medium may be any tangible medium that contains or stores a program that can be used by or in conjunction with an instruction execution system, apparatus, or device. In this application, howeve...

Abstract

The invention relates to an off-line prepayment electric quantity recharging method and system in the technical field of electric power systems. The method comprises the following steps that a first trigger transmission token, a big data transmission token and a recharging data transmission token on an electricity selling system are obtained; decrypting the first trigger transmission token, screening the first trigger transmission token needing to enter a transmission state, and obtaining first plaintext data of the second trigger transmission token and the total number of strings needing to be transmitted by the big data transmission token; decrypting the big data transmission token to obtain second plaintext data, and judging whether each string of second plaintext data is received or not; decrypting the top-up data transmission token to obtain third plaintext data, and calculating a top-up verification value; whether the recharge verification value is the same as the verification code of the third civilized data and whether the receiving string number is the same as the total string number are judged, and if yes, electric quantity recharge is allowed, the instrument parameter setting accuracy is improved, the situation that a single-string token encryption and authentication transmission mode cannot avoid the influence of human factors is broken through, and the safety of an instrument is improved. And confusion of electricity price deduction is caused.
