Abstract
The utility model relates to a IC card, including the main control chip who is connected with button, IC card chip, power management circuit, with power management circuit connection's chargeable call, wherein main control chip can be learnt chargeable call's residual capacity, still be provided with with what main control chip connected can show chargeable call's residual capacity's battery indicator module. The unable residual capacity who shows built -in battery of current IC card adopts IC card, can in time show the residual capacity of the battery in the IC card, the suggestion is charged, avoids leading to the unable work of IC card because the electric quantity is low excessively.
Description
Technical field
The utility model relates to a kind of IC-card, especially relates to a kind of IC-card that can show the dump energy of IC-card internal battery.
Background technology
Traditional IC-card (or being called CPU card) only has contact card or non-contact card function, because components and parts are few, low in energy consumption and communication interface is single, so IC-card provides power supply by the external equipment with its communication.Along with new communication interface introduces (such as bluetooth communication) and the increase of other supplementary module, the components and parts of IC-card inside also increase gradually, cause IC-card to need an internal battery to provide power supply for functional module.Under normal circumstances, internal battery requires can repeatedly charge, to ensure that IC-card has longer serviceable life.Because IC-card adds rechargeable battery, and when user uses, do not know the rechargeable battery of IC-card also remains how many electricity, often make troubles to user.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of IC-card, and this IC-card can show the dump energy of battery built-in in IC-card, and prompting user charges in time.
For reaching above object, the technical solution adopted in the utility model is a kind of IC-card, comprise the main control chip being connected with button, IC card chip, electric power management circuit, the rechargeable battery be connected with described electric power management circuit, wherein said main control chip can know the dump energy of described rechargeable battery, is also provided with the electricity quantity display module that can show the dump energy of described rechargeable battery be connected with described main control chip.
Further, described main control chip knows the dump energy of described rechargeable battery by the described electric power management circuit that can charge and overcharge management to described rechargeable battery.
Further, described electricity quantity display module is several LED.
Further, described main control chip controls described LED and shows according to adopt in various degree different colors and the lighting mode of the dump energy of described rechargeable battery.
Further, described main control chip is bluetooth main control chip.
The beneficial effects of the utility model have following some:
1. can show the dump energy of the battery in IC-card in time, prompting charging, avoid because the too low IC-card that causes of electricity cannot work;
2. staff can control charging operations and duration of charging according to the display of dump energy, extends the life-span of battery and IC-card;
3. electric power management circuit can prevent over-charging of battery, protection battery life.
Accompanying drawing explanation
Fig. 1 is the structural drawing of IC-card described in the utility model embodiment;
In figure: 1-button, 2-electricity quantity display module, 3-main control chip, 4-IC the core of the card sheet, 5-electric power management circuit, 6-rechargeable battery.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, a kind of IC-card, comprises the main control chip 3 be arranged in IC-card, button 1, IC card chip 4, electric power management circuit 5, rechargeable battery 6.Wherein, button 1, IC card chip 4, electric power management circuit 5 are connected with main control chip 3 respectively, and rechargeable battery 6 is connected with electric power management circuit 5.In addition, main control chip 3 can know the dump energy of rechargeable battery 6 by electric power management circuit 5, also be provided with the electricity quantity display module 2 that can show the dump energy of rechargeable battery 6 be connected with main control chip 3 in IC-card, main control chip 3 can show the dump energy of rechargeable battery 6 by controlling electricity quantity display module 2.
Electricity quantity display module 2 is 4 LED in the present embodiment, also can adopt other the hardware module (such as liquid crystal display) that can show battery electric quantity.After user is started shooting by button 1, main control chip 3 can know the dump energy of rechargeable battery 6, and informs user with LED.Main control chip 3 controls LED and shows according to adopt in various degree different colors and the lighting mode of the dump energy of rechargeable battery 6, such as, battery electric quantity can be divided into 4 grades, when battery electric quantity is full of, 4 LED (now LED can green show) can be lighted, when electric quantity consumption one half, 2 LED can be lighted, when the batteries are low, a LED (now LED can red or flickering display to inform that user should charge) is only lighted.
Main control chip 3 is core cells of IC-card provided by the utility model, controls each other unit in IC-card.In the present embodiment, main control chip 3 is bluetooth main control chips, bluetooth main control chip is except can realizing communicating with the external equipment such as mobile phone, IPAD with bluetooth communication interface, communication (communication modes can be ISO7816/SPI/IIC etc.) can also be carried out with IC card chip 4, control electric power management circuit 5, know the dump energy of rechargeable battery 6, control the display of electricity quantity display module 2 (LED) according to remaining battery power.
IC card chip 4 is the same with traditional IC-card or CPU card function, the built-in little operating system that can manage various file, secret key and carry out safe computing.IC card chip 4 can have contact card or non-contact card function.In IC-card provided by the utility model, IC card chip 4 can also carry out communication with main control chip 3 (bluetooth main control chip), for external master chip provides data to calculate and Processing Interface.
Button 1 can provide startup and shutdown to operate for IC-card, button can also be provided to confirm operation for user.Such as, when use carries out signature operation with the IC-card that bluetooth main control chip is main control chip 3, user can agree this time signature by " confirmation " key on button 1, also this time can sign by showing by " cancellation " key table on button 1 to cancel.
Rechargeable battery 6 is that other unit (bluetooth main control chip, IC card chip 4 and electricity quantity display module 2) in IC-card provide power supply by electric power management circuit 5.
Electric power management circuit 5 is mainly used in carrying out control and management to the power supply of other unit in IC-card, and can charge to rechargeable battery 6 and overcharge management, has the function preventing over-charging of battery.
Device described in the utility model is not limited to the embodiment described in embodiment, and those skilled in the art draw other embodiment according to the technical solution of the utility model, belongs to technological innovation scope of the present utility model equally.
