Description
Technical field
The utility model relates to a kind of hand-held power control circuit of veritifying the appearance card reading module of Certification of Second Generation that is applicable to.
Background technology
Along with popularizing of second generation identity card, the use of China second-generation identity card reader has also more and more widely become one of indispensable office appliances in a lot of fields such as public security, education and business administration.Certification of Second Generation is veritified appearance and is used to read Certification of Second Generation information; And the information database that combines to prestore is compared and is veritified; The final purpose that realizes that identity is veritified is widely used in the systems such as examinee's examination management, staff attendance management, for the enforcement of management work provides the support on the reliable technique.
The hand-held power supply of veritifying appearance adopts two kinds on direct insertion power supply and storage battery usually, and we know that disposable battery all is in not by the state of reasonable recovery always, and is very serious to the pollution of environment; Though there is not environmental pollution problems in direct insertion power supply; But for portable equipment, carry and the convenience that uses is the problem that must consider, direct insertion power requirement is hand-held to be veritified appearance and in use keeps and being connected of supply socket always; This has brought very big inconvenience for the hand-held use of veritifying appearance; And, in case accident power-off occurs, will directly cause veritifying losing even damage equipment of appearance data.
The utility model content
The purpose of the utility model is to solve the deficiency of prior art, but a kind of not only straight cutting socket power supply is provided but also can adopt lithium battery power supply, reasonable in design, easy to use, power supply is stable and low in energy consumption is applicable to the hand-held power control circuit of veritifying the appearance card reading module of Certification of Second Generation.
The purpose of the utility model realizes through following technical scheme: be applicable to the hand-held power control circuit of veritifying the appearance card reading module of Certification of Second Generation; It comprises power supply, power supply switch circuit, charging chip, reserve battery, electronic switch, card reading module load and microcontroller; The card reading module load comprises Card Reader circuit and security module; The voltage input of power supply switch circuit connects power supply; One tunnel output of power supply switch circuit is connected with the voltage input end a of electronic switch; Another road output of power supply switch circuit is connected with the voltage input end b of electronic switch with reserve battery through charging chip in order, and the voltage output end of electronic switch is connected with Card Reader circuit and security module; The enable signal input of power supply switch circuit and electronic switch all links to each other with the control signal output ends of microcontroller.
The described reserve battery of the utility model comprises lithium battery.
The beneficial effect of the utility model is:
(1) when power supply is system's normal power supply; Through charging chip subsequent use lithium battery is charged; Can call the load of subsequent use lithium battery reading card module when breaking off power supply and supply power, reasonable in design, easy to use and carry; Power supply is stable, has effectively avoided the loss of data that accident power-off causes or the damage of equipment;
(2) but give the independent power supply of Card Reader circuit or security module through the electronic switch Intelligence Selection, when only needing the antenna Card Reader, only open the Card Reader circuit; When carrying out the Certification of Second Generation decrypts information after Card Reader is accomplished, only open security module; Thereby effectively reduce system power dissipation, prolonged the useful life of battery.
