Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, specific technical solutions of the present application will be described in further detail below with reference to the accompanying drawings in the embodiments of the present application. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
It should be noted that the terms "first \ second \ third" are used herein to distinguish similar or different objects and do not denote a particular order or importance to the objects, and it should be understood that "first \ second \ third" may be interchanged with a particular order or sequence where permissible to enable embodiments of the present application described herein to be practiced otherwise than as shown or described herein.
The embodiment of the application provides control of a fingerprint sensor, and the method is applied to electronic equipment, and the electronic equipment can be various types of equipment with the fingerprint sensor in the implementation process, for example, the electronic equipment can comprise a mobile phone, a tablet computer, a fingerprint door lock and the like. The functions implemented by the method can be implemented by calling program code by a processor in an electronic device, and the program code can be stored in a computer storage medium.
Fig. 1 is a schematic implementation flow diagram of a control method of a fingerprint sensor provided in an embodiment of the present application, and as shown in fig. 1, the method may include the following steps 101 to 103:
In the embodiment of the present application, the timing for acquiring the fingerprint sensor is not limited, that is, the timing for detecting whether the fingerprint sensor is damaged or not is not limited. The method can be used for detecting whether the fingerprint sensor is damaged or not at any time in the starting state of the electronic equipment or when certain specific trigger conditions are met, for example, when the working current of the fingerprint sensor is greater than a current threshold; for another example, when the electronic device is powered on, whether the fingerprint sensor is damaged is detected.
In some embodiments, the temperature sensor is in a low power consumption state without certain specific triggering conditions being met. For example, the temperature sensor is not powered, and the electronic device powers the temperature sensor when certain specific triggering conditions are met; for another example, the temperature sensor detects the temperature of the fingerprint sensor at a lower detection frequency, and the electronic device controls the temperature sensor to detect the temperature of the fingerprint sensor at a higher detection frequency when certain specific trigger conditions are met. Therefore, the method can save the power consumption of the electronic equipment.
Understandably, if the fingerprint sensor is damaged, the electronic equipment can cut off the power supply circuit of the fingerprint sensor at the moment, so as to stop supplying power to the fingerprint sensor; if the fingerprint sensor is not damaged, it may be returned to step 101 after a certain period of time, so as to detect again whether the fingerprint sensor is damaged.
In an embodiment of the application, the electronic device may determine whether the fingerprint sensor is damaged according to the temperature or according to the temperature and other indexes. For example, if the temperatures detected for a plurality of consecutive times are all greater than the temperature threshold, it is determined that the fingerprint sensor is damaged; for another example, the other index is an index that can reflect the fingerprint sensor being damaged, for example, the index is an operating current, and if the temperature detected for one or more consecutive times is greater than a temperature threshold value and the operating current is greater than a current threshold value, the fingerprint sensor is determined to be damaged. The other indexes are not limited to the index of the operating current, and may be any index that can reflect whether the fingerprint sensor is damaged.
In the present application, the size of the temperature threshold is not limited, and the value may be any temperature value that the human body cannot bear. For example, the temperature threshold may be any value in the interval [45 ℃,50 ℃ ]. Of course, other values outside this interval are also possible.
And 103, stopping supplying power to the fingerprint sensor if the fingerprint sensor is damaged.
In some embodiments, the electronic device may also output an alert message when it is determined that the fingerprint sensor is damaged, the alert message for alerting the user to refrain from touching the fingerprint area to avoid burning the finger. The manner for the output may be varied. For example, a window containing the reminding information pops up on the current interface of the electronic equipment. As another example, the reminding purpose is achieved by voice or special alarm sound.
In the embodiment of the application, whether the fingerprint sensor is damaged or not is determined at least according to the temperature of the fingerprint sensor detected by the temperature sensor; therefore, on one hand, whether the fingerprint sensor is damaged or not can be accurately detected, and power supply to the fingerprint sensor is stopped under the condition of damage, so that the phenomenon that a user is scalded due to overhigh temperature of the fingerprint sensor is avoided; on the other hand, in the whole process, the working mode of the fingerprint sensor does not need to be interrupted, the fingerprint identification mode of the fingerprint sensor does not need to be switched to the acquisition mode of detection data (namely, the basis for detecting whether the fingerprint sensor is damaged), the fingerprint identification mode interacts with the temperature sensor independent of the fingerprint sensor, the temperature of the fingerprint sensor is acquired from the temperature sensor, whether the fingerprint sensor is damaged or not is judged based on the temperature, and therefore the mode can not cause the problem that the fingerprint sensor is large when responding to the touch time delay of a user, namely, the experience of the user for using the fingerprint sensor is not influenced.
Fig. 2 is a schematic flow chart illustrating an implementation of the control method of the fingerprint sensor according to the embodiment of the present application, and as shown in fig. 2, the method includes the following steps 201 to 205:
it can be understood that, in the embodiment of the application, whether the fingerprint sensor is damaged or not can be more accurately judged according to more indexes of the fingerprint sensor, so that the influence of misjudgment on user experience is reduced.
In some embodiments, the electronic device may control the temperature sensor to detect the temperature of the fingerprint sensor one or more times, thereby acquiring the temperature detected by the temperature sensor one or more times. When the working current is greater than the current threshold value and the temperatures acquired for M times are greater than the temperature threshold value, determining that the fingerprint sensor is damaged; wherein M is an integer greater than 0.
It is understood that when M is greater than 1, whether the fingerprint sensor is damaged or not can be determined more accurately.
An embodiment of the present application further provides a method for controlling a fingerprint sensor, and fig. 3 is a schematic implementation flow chart of the method for controlling a fingerprint sensor according to the embodiment of the present application, and as shown in fig. 3, the method includes the following steps 301 to 308:
and acquiring the temperature of the fingerprint sensor from the temperature sensor under the condition that the working current is larger than a current threshold value. For example, the temperatures detected by the temperature sensor a plurality of times are acquired by the following step 305.
It will be appreciated that an operating current anomaly is likely to be a fingerprint sensor that is damaged, and therefore, in some embodiments, the operating current of the fingerprint sensor has a higher priority than the temperature. Thus, whether the working current is larger than the current threshold value is judged; if the working current is too large, the fingerprint sensor is likely to be damaged, and whether the temperature of the fingerprint sensor is abnormal is further detected; if the temperature is abnormal, the power supply circuit of the fingerprint sensor is cut off, so that the user is prevented from being scalded when touching the fingerprint sensor; moreover, the method has higher judgment accuracy, so that the influence of misjudgment on user experience can be reduced;
if the working current is less than or equal to the current threshold, the fingerprint sensor is not damaged at a high probability, and further detection work is not carried out at the moment, namely, the temperature sensor does not need to be started to detect the temperature, so that the power consumption is saved.
and 305, controlling the temperature sensor to detect the temperature of the fingerprint sensor for multiple times, so as to acquire the temperature detected by the temperature sensor for multiple times.
It can be understood that, in most cases, the fingerprint sensor is not bad, so that when the operating current is greater than the current threshold, it is very likely that the fingerprint sensor is bad, and the temperature sensor is turned on to detect the temperature, so that the power consumption of the electronic device can be saved.
In some embodiments, the temperature sensor is a temperature sensor abutting against a lower surface of a sensing panel of the fingerprint sensor; therefore, the temperature detected by the temperature sensor is closer to the actual temperature of the fingerprint sensor, so that the accuracy of judging whether the fingerprint sensor is damaged or not can be improved, and the problem of poor user experience caused by misjudgment is prevented. For example, if the actual temperature of the fingerprint sensor is greater than the temperature threshold, but if the detection error of the temperature sensor is large, if the detected temperature is less than the actual temperature and also less than the temperature threshold, it should be determined that the fingerprint sensor is damaged, but it is determined that the fingerprint sensor is not damaged, the power supply of the fingerprint sensor is not cut off, and the fingerprint sensor is still in a state of continuously increasing temperature, so obviously, when the user touches the fingerprint area, the user may be scalded.
and 307, stopping supplying power to the fingerprint sensor, and outputting reminding information, wherein the reminding information is used for reminding a user of not touching the fingerprint area so as to avoid scalding.
It is understood that if the temperature of the fingerprint sensor acquired N times (for example, 3 times or 6 times) is greater than the temperature threshold, the power supply circuit of the fingerprint sensor is cut off, and the power supply to the fingerprint sensor is stopped.
In step 308, a third timer is started, and when the time of the third timer expires, the step 301 is executed again, or the step 305 is executed again.
In the related art, a main control terminal reads a chip identifier (chip id) of a fingerprint sensor, and if the chip identifier cannot be read correctly, the fingerprint sensor is considered to be damaged. However, in some cases, the failure to read the chip identifier may be due to other reasons than the fingerprint sensor being damaged. Therefore, the method has high misjudgment probability, when the fingerprint sensor is not damaged and is judged to be damaged, the main control end performs power-off processing on the fingerprint sensor, and then if a user touches the fingerprint area, no sensing condition occurs, namely, the user cannot use the fingerprint function, so that the use experience of the user is influenced.
In another related technology, the main control end switches the fingerprint sensor to the FTD mode and collects data of the FTD block; then judging whether the data are saturated up and down according to the collected data; if saturation occurs, the fingerprint sensor is considered to be broken.
Above-mentioned prior art's arbitrary condition satisfies, then think that fingerprint sensor damages, and the main control end draws the module that resets of fingerprint reset pin down, and 3 consecutive detections all appear unusually, then think that fingerprint sensor thoroughly damages, and the main control end carries out the outage with fingerprint sensor this moment and handles.
It can be understood that the related art cannot accurately detect if the FDT sensing area (i.e. some small area where the IC is fixed) of the fingerprint sensor is not damaged but the non-FDT area is damaged or other devices inside the fingerprint sensor are short-circuited or damaged. Problems with these components can also cause the fingerprint sensor to be too hot.
In some special situations, there is a probabilistic misjudgment, for example, static electricity may strike the fingerprint sensor, and the static electricity may cause an abnormal FDT sensing region of the fingerprint sensor, thereby causing the misjudgment.
In addition, the related art needs to frequently detect whether the fingerprint sensor is abnormal in multiple scenes, such as on/off screen scenes, and initiate a scene before fingerprint identification. Each detection needs 20-30 ms, so that the fingerprint identification speed is influenced, and poor user experience is caused. The reason is that before the main control end collects the data of the FTD block, the fingerprint sensor needs to be switched from the fingerprint identification mode to the FTD mode, and the main control end can interact with the fingerprint sensor in the FTD mode to obtain FTD data; the process takes 20-30 ms.
Based on this, an exemplary application of the embodiment of the present application in a practical application scenario will be described below.
In the embodiment of the present application, a control method of a fingerprint sensor is provided, as shown in fig. 4, a temperature sensor detects the temperature of the fingerprint sensor in real time, a main control end periodically queries temperature values detected by the temperature sensor, and determines whether the temperature of the fingerprint sensor is abnormal according to the temperature values; and if the fingerprint sensor is abnormal, the power supply circuit between the fingerprint sensor and the power supply is disconnected, and the power supply for the fingerprint sensor is stopped.
An embodiment of the present application further provides a method for controlling a fingerprint sensor, as shown in fig. 5, the method includes the following steps 501 to 504:
and step 504, the main control end turns off the power supply of the fingerprint sensor and prompts the user that the fingerprint function is abnormal.
In this application embodiment, the temperature of direct detection fingerprint region to when the temperature of the fingerprint region that detects 3 times in succession all exceeded 50 degrees centigrade, closed fingerprint sensor's power, thereby can effectively avoid correlation technique to the inaccurate defect of the discernment of fingerprint sensor whether damage, whether the detection fingerprint module that can be more accurate is temperature anomaly, avoids the problem that the user was scalded to the high temperature.
And because the main control end does not need to switch the fingerprint sensor from the fingerprint identification mode to the FTD mode first, but directly obtains the temperature of the fingerprint sensor from the temperature sensor, and the temperature is compared with FTD data, and the data volume is very little, it can be seen that the method of the embodiment of the application consumes less time, and can not interrupt the current working mode of the fingerprint sensor, therefore, the identification speed and the stability of the fingerprint sensor are not influenced.
In the embodiment of the application, the temperature of the fingerprint sensor is directly detected through the temperature sensor, so that various defects (such as inaccurate detection, time consumption, poor stability and the like) of the current mainstream scheme can be avoided, whether the temperature is too high can be accurately judged, and the problem that a user is scalded due to damage of the fingerprint sensor is avoided.
Detecting whether the fingerprint sensor is damaged, in principle:
(1) the main control end sends an instruction to instruct the fingerprint sensor to switch to a self-checking mode, and the fingerprint sensor detects whether the fingerprint sensor is abnormal.
(2) A temperature sensor is added to monitor the temperature of the fingerprint sensor.
(3) The main control end monitors the change of the working current of the fingerprint sensor, and when the working current is too large (if the working current is larger than a current threshold), the fingerprint sensor is considered to be damaged.
Based on the foregoing embodiments, the present application provides a control apparatus for a fingerprint sensor, where the apparatus includes modules and units included in the modules, and may be implemented by a processor; of course, the implementation can also be realized through a specific logic circuit; in implementation, the processor may be a Central Processing Unit (CPU), a Microprocessor (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like.
