Technical field
The utility model relates to a kind of special-purpose payment cipher, and it belongs to the terminal that the financial sector electronic bill signs and issues and check and accept and establishes
Be equipped with class.
Background technology
Test poor, the unmanageable shortcomings such as settlement efficiency is low, financial risks of India side formula anti-counterfeit capability to traditional bill, cash melts industry and has adopted payment coding system mostly, also is referred to as the electronic payment secret code system.Its principle is the payment cipher that enterprise utilizes issued by banks; When the issuance of a note, utilize payment cipher to each key element on the bill, like account number; Carry out comprehensive cryptographic calculation date of draft etc. and produce payment cipher; The perhaps payment cipher of bank's supporting a kind of corresponding bill of printing with password envelope mode number when ticket issuing, enterprise's payment cipher that bill is corresponding when the issuance of a note fills on the bill, as the assistant identification means of the main identification of means or the seal of papers.Calendar year 2001 People's Bank of China and State Encryption Management Committee associating formulate at this point and issued " payment cipher versatility technical manual "; According to the requirement of " payment cipher versatility technical manual ", payment cipher generally comprises data input, information demonstration, data-storing, dedicated serial communication port and payment cipher special chip etc. and partly constitutes.A kind of typical in the prior art, the payment cipher that meets " payment cipher versatility technical manual " is that CN02231555.1 is disclosed, and the disclosed this payment cipher of CN02231555.1 comprises housing; Be provided with circuit arrangement in the said housing, said circuit arrangement comprises display unit, keyboard unit, storage unit, 232 communication units; AES unit, power supply unit and MCU, said power supply unit provides power for operation to other each unit, and other each unit all is connected to MCU; Said keyboard unit comprises 18 enter keies, and comprising upper and lower, left and right four direction key, the problem that this payment cipher of prior art exists is that processing speed is slow, job insecurity; And complicated operation easy error; What its reason was its clock circuit employing of this payment cipher is MCU clock internal circuit, and MCU clock internal circuit can only ensure MCU stable operation by default, then can be extremely unstable to improve processing speed if improve the running frequency of MCU; Moreover; The power supply unit of payment cipher is generally battery, when battery electric power descends, and the payment cipher easy error.This payment cipher of prior art comprises upper and lower, left and right four direction key, in order to import the position of cursor on display unit in order to adjustment respectively; Left and right directionkeys is used for horizontal adjustment, and upper and lower directionkeys is used for adjusting up and down, and payment cipher display unit content displayed is very limited; The four direction key is set in this case operates the complicacy of the operation of obvious increase; There are some researches show, change key operation once, be equivalent on a button, operate 6 times; The above, obviously prior art has further improved necessity.
Summary of the invention
The purpose of the utility model is to provide a kind of special-purpose payment cipher, to overcome the problem that prior art exists.
A kind of special-purpose payment cipher of the utility model; Comprise housing, be arranged on the circuit arrangement in the housing, said circuit arrangement comprises display unit, keyboard unit, storage unit, 232 communication units; AES unit, power supply unit and MCU; Said power supply unit provides power for operation to other each unit, and other each unit all is connected to MCU, and said display unit and keyboard unit are arranged on the housing; It is characterized in that also comprising clock unit, power management alarm unit, said clock unit and power management alarm unit all are connected to MCU.
This special-purpose payment cipher of the utility model owing to adopted external clock unit, for this reason in the processing speed that promotes MCU, promotes the treatment effeciency of payment cipher; This payment cipher of the utility model; Owing to set up the power management alarm unit; For this reason in power supply unit institute power supply power deficiency so that MCU normal and stable when work, will send that alerting signal prompting operation person changes or to battery charge, thereby effectively prevent the possibility of makeing mistakes.
As preferably; Said power supply unit is connected to the power management alarm unit; To other each unit electric power is provided through the power management alarm unit; PMU also can cut off the electric power of payment cipher at this moment except that sending the warning under with the situation of guaranteeing the MCU operate as normal in power shortage that PMU provides at the power management alarm unit like this, makes it shutdown.
As further improvement, said keyboard unit comprises several buttons, comprises the direction button in several buttons, and said direction button is made up of two different direction buttons of direction of operating.Because payment cipher display unit content displayed is very limited, it will be feasible cooperating the adjustment that realizes full frame input cursor through two different directionkeys for this reason, will improve operating efficiency so simultaneously.
As further improvement, also comprise the IC-card interface unit, said IC-card interface unit is connected to MCU, and the payment cipher of the utility model payment cipher that can write direct and generate to electronic payment certificate is convenient for users to use like this.
