Description
Technical field
The utility model relates to a kind of battery voltage detector, relates in particular to a kind of battery voltage detector that is used on the mobile battery charger.
Background technology
Development along with society; the popularity rate of mobile phone is also more and more higher; most mobile phone charges by charger; but when people go out, usually can forget charger for mobile phone is carried; if this time, mobile phone did not have electricity; just must go back to get charger for mobile phone or find the charger for mobile phone of same model, bring very big inconvenience for people's life.
A kind of mobile battery charger had appearred on the market afterwards, such mobile battery charger has a plurality of chucks, when using, only need drop into the coin of respective numbers according to the electric weight of mobile phone, and mobile phone linked to each other with mobile battery charger by this chuck, so just can charge fast, thereby solve people's worry that mobile phone do not have electricity not carry charger again of going out, convenient people's life mobile phone.
But can not in time give the client feedback of status of charging because the battery voltage detector of general large-scale mobile battery charger exists, thereby be unfavorable for that client can in time understand the state of battery charge.
Summary of the invention
The utility model provides a kind of battery voltage detector of mobile battery charger, must not in time feed back to the client to the status information of charging to separate, thereby be unfavorable for that client can in time understand the defective of the state of battery charge.
Its structure of the battery voltage detector of mobile battery charger of the present utility model is as follows: this pick-up unit comprises battery polar detection module, battery information transport module, voltage comparator circuit, electric mould modular converter, central processing unit and power module, wherein, battery polar detection module and battery information transport module all are connected to voltage comparator circuit, voltage comparator circuit is connected to central processing unit by electric mould modular converter, also connects power module on the central processing unit.Can make battery after placement, just begin detected whether both positive and negative polarity correct position by this design, be digital signal by electric mould modular converter with analog-signal transitions then, and be transferred to central processing unit and handle, by the electric weight of the real-time monitoring battery of Voltage Feedback that continues.
Further, electric mould modular converter is a change-over circuit that comprises analog to digital converter.
It is as follows to have the process that this mobile battery charger of battery voltage detector charges: the coin that drops into respective numbers at coin slot according to the length in duration of charging, at this moment, if the coin that the coin detection module detects is that counterfeit money or client want to move back coin, just can be by moving back the coin button, at this moment, coin storehouse control module can withdraw from coin to the coin storehouse unlatching of moving back of below, coin storehouse according to the control signal on the cpu motherboard, simultaneously, if drop into is that genuine note and failed call move back the coin operation, sensor in the coin detection module can detect the quantity that inserts coin, and signal is transferred on the cpu motherboard by the serial communication module, cpu motherboard control charging storehouse switch control module is opened the charging storehouse, like this, battery of mobile phone is put into the charge position of charging in the storehouse, the charging storehouse is closed, at this moment, whether the battery plus-negative plate detection module begins the position of detection of handset battery correct, that is: whether battery plus-negative plate is positioned on the probe of mobile battery charger, if malposition, the battery plus-negative plate detection module is sent to signal on the cpu motherboard by the serial communication module, cpu motherboard control charging storehouse switch control module is opened the charging storehouse and is controlled voice module and accesses corresponding voice document prompting client and reappose battery, if battery location is correct, charging module begins battery is charged, and the prompting client is provided with password, the password that client oneself sets from the keyboard input, the keyboard scan control module is transferred to the password setting module to this password by cpu motherboard and stores, in this process, the charging ambient temperature detection module can detect the temperature of charging in the storehouse by temperature sensor always, if this temperature is too high, system can be transferred to cpu motherboard to signal, and the control power module is stopped power supply.When battery of mobile phone charged normal, the battery voltage detection module can detect the voltage of battery always, and demonstrated the state of charging, the i.e. state of reminding client to charge by the bright quantity of display reminding lamp by the acousto-optic display module.After charging is finished, the display reminding lamp of acousto-optic display module is all bright, the voice module of cpu motherboard control simultaneously carries out voice suggestion, the charging storehouse of this moment is still closed, client must input password from keyboard once more, Shu Ru password can compare this password transmission by the keyboard scan control module to password setting module and the previous password that is provided with once more, if this password bad, voice module can be pointed out and be re-entered password, if this password is correct, the charging storehouse can be opened, and client just can take out battery.Wherein, the infrared detection module is by an infrared probe observation external world whether people's process to be arranged, and this signal is transferred to cpu motherboard, accesses corresponding voice document by cpu motherboard control voice module, and for example: hello, welcome etc.The oxygen disinfection module of living is to work in the process that mobile phone charges always, and continues to discharge oxygen, purifies air, and makes airtight indoor air quality be improved.
The beneficial effect of the battery voltage detector of the utility model mobile battery charger is: by this battery voltage detector, make the state of the real-time monitoring battery of this cell-phone charging function charging, and in time charge information is fed back to client, convenient client.
