S110, in journal file, the daily record data of the pressing interrupt signal that takes the fingerprint.Fingerprint pressing interrupt signal is finger
Produce during line module identification fingerprint pressing operation, and report to hardware abstraction layer HAL.
In the existing terminal with fingerprint recognition, the fingerprint module positioned at terminal hardware bottom is in identification fingerprint pressing operation
Afterwards, the fingerprint pressing interrupt signal for generally producing identification is conveyed directly in corresponding bsp driver or drive circuit,
Do not report to the system layer of terminal system.When fingerprint module occurs exception cannot carry out fingerprint recognition, can cause not refer to
Line pressing interrupt signal goes execution to complete subsequent operation to follow-up driving equipment.Because there is the core in system in aforesaid operations
Lamella, system level cannot be perceived, therefore, when carrying out completing such as terminal unlocking, APP password confirmings in terminal by fingerprint recognition
Deng operation failure when, system level can not know, it is abnormal to be that fingerprint module occurs, or its subsequent drive for causing is in operation
When occur it is abnormal.
The present embodiment on the basis of existing technology, by terminal system between chip bottom and the centre of system layer
Layer such as hardware abstraction layer (Hardware Abstraction Layer, HAL) is pressed to perceive and transmit fingerprint module identification fingerprint
The behavior of press operation.
For example, the function of reporting fingerprint to press interrupt signal to hardware abstraction layer HAL can be increased in existing fingerprint module
Unit, the functional unit by netlink interfaces be located at HAL layers fingerprint pressing interrupt signal reading thread be connected, with
During fingerprint module identification fingerprint pressing operation, to it produced fingerprint pressing interrupt signal is reported.Meanwhile, increase in HAL layers
One reading thread for being used to read fingerprint pressing operation is set, and the reading thread can periodically read fingerprint module identification fingerprint and press
The fingerprint pressing interrupt signal of HAL layers is reported to during press operation.The fingerprint pressing that reading fingerprint module is reported is received thread is read
During interrupt signal, system layer will read the behavior of thread in normal recordings HAL layer, and produce corresponding daily record data storage
In journal file in terminal.By the way that in journal file, fingerprint module identification fingerprint pressing in search and extraction terminal is grasped
As when report fingerprint pressing interrupt signal to hardware abstraction layer HAL produced by daily record data, it is possible to learn fingerprint module produce

It is no exception occur.
For example, if pressing the data of interrupt signal in daily record data comprising fingerprint, characterizing fingerprint module can normally recognize
Fingerprint pressing operation in terminal, thereby determines that exception does not occur in fingerprint module；
If pressing the data of interrupt signal in daily record data not comprising fingerprint, characterizing fingerprint module can not normally recognize end
Fingerprint pressing operation on end, thereby determines that fingerprint module occurs abnormal.
Further, if pressing the data of interrupt signal in the daily record data for extracting comprising fingerprint, and fingerprint module is recognized
The terminal operation exception caused after fingerprint pressing operation, it is determined that perform the unit exception of terminal operation.
For example, when the detection of unlocked by fingerprint operation is carried out to terminal, if extracted in the journal file from terminal
Fingerprint module recognizes fingerprint pressing operation and reports the daily record number produced by fingerprint pressing interrupt signal to hardware abstraction layer HAL
According to, and terminal is not unlocked successfully, then show that the modular unit for performing terminal unlocking function occurs abnormal, it is impossible to normal work
Make.
The detection method of the fingerprint module operation irregularity of the embodiment of the present invention, is referred to by fingerprint module identification in detection terminal
Report fingerprint to press the behavior of interrupt signal to hardware abstraction layer HAL during line pressing operation, carry in the journal file in terminal
Take the daily record data that behavior correspondence is produced；Then by the daily record data for extracting, judge whether fingerprint module really recognizes
