Abstract
The utility model relates to a handset with a fingerprint key, which comprises a handset body and a circuit part additionally arranged in the present circuit of the handset body and formed by connecting a communication interface circuit and a fingerprint sensor circuit, wherein, the fingerprint sensor circuit and the communication interface circuit are respectively connected with a portion interface of a CPU processing chip U4 of the handset, and the communication interface circuit is an IrDA interface circuit or an RF radio frequency interface circuit or other interface circuits; the fingerprint sensor circuit is composed of a sensor chip U1 and a peripheral circuit, the IrDA interface circuit is mainly composed of an interface chip U3 and a peripheral circuit, and signal data is transferred by the IrDA interface circuit and an execution mechanism controlled by a key. The utility model has the advantages that the security of the handset is enhanced by collecting fingerprint information and identifying fingerprints of users, the handset is proceed with the functions of remote opening and closing door access or other instruments and equipment, and the function of the remote control key can be started only by the fingerprints of legal users.
Description
Technical field
The utility model relates to field of wireless communication, and especially a kind of behind identification user fingerprint, the long-range actuator of energy remote control finishes the mobile phone of the band fingerprint key of breakdown action.
Background technology
At present, known mobile phone only possesses call function.Its deficiency is: the legitimacy that can not discern the user; And do not have a function of remote control switch.
Summary of the invention
Can not differentiate the user in order to overcome existing mobile phone, and the limitation that can only converse and use, the purpose of this utility model provides a kind of mobile phone with the fingerprint key.This mobile phone can not only be differentiated end user's fingerprint, and various actuators of remote control easily, function such as finish corresponding unlatching, close.
The technical scheme that its technical problem that solves the utility model adopts.The mobile phone of this band fingerprint key comprises the mobile phone main body, in the existing circuit of mobile phone body, adds the circuit part that is connected to form by communication interface circuit and fingerprint sensor circuit; Wherein fingerprint sensor circuit and communication interface circuit join with the part interface of mobile phone CPU process chip U4 respectively.
The technical scheme that its technical problem that solves the utility model adopts can also be further perfect.Described communication interface circuit is an IrDA interface circuit or for the RF radio-frequency interface circuit or for other interface circuits.Fingerprint sensor circuit is made of sensor chip U1 and peripheral circuit, and the IrDA interface circuit mainly is made of interface chip U3 and peripheral circuit, carries out signal data by the IrDA interface circuit with the actuator that is subjected to key control and transmits.Software resources such as algorithm for recognizing fingerprint, fingerprint key management algorithm are incorporated in the software systems of former mobile phone.Behind the mobile phone power-on, at first verify user's fingerprint,, realize the function of conversation or remote control switch respectively then according to different needs.
1), mobile phone can gather finger print information, and end user's fingerprint is identified, improves the fail safe of mobile phone the effect that the utility model is useful is:; 2), make mobile phone have the function that remote control opens and closes gate inhibition or other utensils, equipment.3), only could start the remote-control key function with legal user's fingerprint.
