[0051] Figure 1 The electronic device shown is merely illustrative and does not in any way imply any limitation on the present disclosure, its application or use. In the embodiments of the present disclosure, the memory 1200 of the electronic device 1000 is used to store instructions, and the instructions are used to control the processor 1100 to operate to perform any one of the methods provided in the embodiments of the present disclosure. It should be understood by those skilled in the art that although Figure 1 In the electronic device 1000, multiple devices are shown, but the present disclosure may only involve some of the devices, for example, the electronic device 1000 only involves the processor 1100 and the storage device 1200. A technician can design instructions according to the scheme disclosed in the present disclosure. How instructions control the processor to operate is well known in the art, so it will not be described in detail here.

[0052] This embodiment provides a temperature detection method. The temperature detection method can be implemented by an electronic device, which can be Figure 1 The electronic device 1000 is shown. Figure 2 As shown, it includes steps S2100 to S2200 as shown below:

[0053] Step S2100, obtaining a first stable temperature of a first detection point in the electronic device and a second stable temperature of a second detection point in the electronic device.

[0054] In this embodiment, at least one temperature sensor may be provided in the electronic device, and the at least one temperature sensor may detect the temperature of the first detection point and the temperature of the second detection point.

[0055] In this embodiment, the stable temperature of any detection point may be the temperature of the detection point after the heat source is continuously applied to the target position of the electronic device for more than a set time. The set time may be set in advance according to the application scenario. After the heat source is continuously applied to the target position for more than a first set time, the temperature of any detection point is basically stable and will not increase as the heat source is continuously applied to the target position. For example, the first set time may be 20 minutes.

[0056] In one embodiment of the present disclosure, the first stable temperature and the second stable temperature may be temperatures collected by at least one temperature sensor after the heat source is continuously applied to the target position of the electronic device for more than a first set time.

[0057] In another embodiment of the present disclosure, the first detection point and / or the second detection point is used as the target detection point, and obtaining the stable temperature of the target detection point includes: obtaining multiple sampling temperatures of the target detection point within the first time period; and determining the stable temperature of the target detection point based on the multiple sampling temperatures.

[0058] The first time period may be a time period starting from the time when the heat source is applied to the target position and lasting for a second set time. The second set time is less than the first set time. The second set time may be set in advance according to the application scenario or specific needs. For example, the second set time may be 3 seconds.

[0059] In this embodiment, the temperature sensor may detect the temperature of the target detection point according to a set sampling frequency in the first time period to obtain a plurality of sampled temperatures of the target detection point in the first time period.

[0060] In one embodiment of the present disclosure, determining a stable temperature of a target detection point according to a plurality of sampling temperatures includes: acquiring first mapping data reflecting a mapping relationship between the sampling temperature and the stable temperature; and obtaining the stable temperature of the target detection point according to the plurality of sampling temperatures and the first mapping data.

[0061] The first mapping data may be a first mapping function, or a first comparison table, etc., which is not limited here.

[0062] For the first mapping function, the dependent variable of the first mapping function is the stable temperature, and the independent variable is the sampling temperature. In this way, by substituting multiple sampling temperatures into the first mapping function, the stable temperatures corresponding to the multiple sampling temperatures can be obtained as the stable temperatures of the target detection points.

[0063] For the first comparison table, the stable temperature corresponding to the multiple sampling temperatures can be found in the first comparison table as the stable temperature of the target detection point. If the sampling temperature cannot be directly found in the first comparison table, the values ​​adjacent to the sampling temperature can be found, and the stable temperature corresponding to the multiple sampling temperatures can be obtained by interpolation according to the adjacent values ​​and the stable temperatures corresponding to the adjacent values, as the stable temperature of the target detection point.

[0064] Step S2200, determining the temperature of the heat source applied to the target position according to the first distance between the first detection point and the target position of the electronic device, the second distance between the second detection point and the target position, the first stable temperature and the second stable temperature.

[0065] In this embodiment, the target position is the position where the heat source is applied in the electronic device, and the first distance is not equal to the second distance.

[0066] In one example, the target position may be the center of a fingerprint input area of ​​an electronic device, so that when a user inputs a fingerprint of a finger to unlock the electronic device, the temperature of the finger can be obtained to control the electronic device according to the temperature of the finger.

[0067] When the heat source presses the target location, the heat conduction direction can be as follows Figure 3 As shown. Different materials have different thermal conductivity coefficients; the thermal conductivity coefficient of the same material is related to its structure, density, humidity, temperature, pressure and other factors. Different heat sources applied to the target position will cause the steady-state temperature of the first detection point and the second detection point to be different. Therefore, the temperature of the heat source applied to the target position is determined based on the first distance, the second distance, the first stable temperature and the second stable temperature.

[0068] Through the embodiments of the present disclosure, the temperature of the heat source applied to the target position can be determined more quickly and accurately based on the first distance between the first detection point and the target position, the second distance between the second detection point and the target position, the first stable temperature of the first detection point, and the second stable temperature of the second detection point.

[0069] In one embodiment of the present disclosure, determining the temperature of a heat source applied to a target position according to a first distance between a first detection point and a target position of an electronic device, a second distance between a second detection point and the target position, a first stable temperature, and a second stable temperature includes steps S2210 to S2220 as shown below:

[0070] Step S2210, determining a stable temperature of the target position according to the first distance, the second distance, the first stable temperature, and the second stable temperature.

[0071] In one embodiment of the present disclosure, determining the stable temperature of the target position according to the first distance, the second distance, the first stable temperature, and the second stable temperature includes steps S2211 to S2213 as shown below:

[0072] Step S2211, determining the distance difference between the first distance and the second distance.

[0073] Step S2212, determining the temperature difference between the first stable temperature and the second stable temperature.

[0074] Step S2213, determining the stable temperature of the target location according to the distance difference and the temperature difference.

[0075] In this embodiment, the stable temperature of the target position can be determined according to the following formula:

[0076]

[0077] Among them, T c represents the first stable temperature, T b Indicates the second stable temperature, T a represents the stable temperature at the target position, N represents the first distance, M represents the second distance, λ represents the thermal conductivity of the material, and K represents the set measurement constant.

[0078] Step S2220, determining the temperature of the heat source applied to the target location according to the stable temperature of the target location.

[0079] In one embodiment of the present disclosure, determining the temperature of the heat source applied to the target location according to the stable temperature of the target location includes steps S2221 to S2222 as shown below:

[0080] Step S2221, obtaining second mapping data reflecting the mapping relationship between the stable temperature and the heat source temperature.

[0081] In this embodiment, the second mapping data may be obtained in advance based on experimental data.

[0082] Step S2222, obtaining the temperature of the heat source applied to the target position according to the stable temperature of the target position and the second mapping data.

[0083] The second mapping data may be a second mapping function, or a second comparison table, etc., which is not limited here.

[0084] For the second mapping function, the dependent variable of the second mapping function is the heat source temperature, and the independent variable is the stable temperature. In this way, by substituting the stable temperature into the second mapping function, the heat source temperature corresponding to the stable temperature can be obtained as the temperature of the heat source applied to the target position.

[0085] For the second comparison table, the heat source temperature corresponding to the stable temperature can be found in the second comparison table as the temperature of the heat source applied to the target position. If the stable temperature cannot be directly found in the second comparison table, two values ​​adjacent to the stable temperature can be found, and the heat source temperature corresponding to the stable temperature can be obtained by interpolation according to the two values ​​and the heat source temperatures corresponding to the two values, as the temperature of the heat source applied to the target position.

[0086] In one embodiment of the present disclosure, the heat source is a user's finger; the method further includes: receiving a fingerprint unlocking operation triggered by the finger in a fingerprint input area, and obtaining the fingerprint of the finger; the target position is the center of the fingerprint input area; when the temperature of the finger is within a preset temperature range and the fingerprint of the finger matches the pre-stored fingerprint, controlling the electronic device to unlock.

[0087] The fingerprint unlocking operation triggered by the finger in the fingerprint input area may be an operation in which the finger starts pressing the fingerprint input area.

[0088] In this embodiment, when a fingerprint unlocking operation is received, steps S2100 to S2200 are performed to obtain the temperature of the finger. In the first period, the finger inputs the fingerprint in the fingerprint input area.

[0089] The temperature of the human skin surface is about 33°C, and the temperature of the human skin surface will fluctuate with the temperature of the external environment. Therefore, in the embodiment of the present invention, a preset temperature range of 30°C-36°C can be input into the electronic device. If the temperature of the finger is within the preset temperature range, the acquired fingerprint of the finger is matched with the pre-stored fingerprint. If the temperature of the finger is not within the preset temperature range, the finger that triggers fingerprint unlocking may be abnormal. For example, a malicious user copies the acquired fingerprint of the user on a prop similar to a finger, and the prop does not have the temperature of the human skin surface. At this time, the electronic device can prompt that the unlocking fails.

[0090] In this embodiment, the fingerprint unlocking method requires measuring the temperature of the finger, which prevents malicious users from copying the user's fingerprint on a finger-like prop after obtaining the user's fingerprint to unlock the electronic device, thereby preventing malicious users from illegally stealing important information of the user on the electronic device.

[0091] In one embodiment of the present disclosure, the heat source is a finger of a user; the method further includes: performing health monitoring on the user according to the temperature of the finger.

[0092] In this embodiment, when the temperature of the finger is not within a preset temperature range, the electronic device may be controlled to issue an alarm to prompt the user that the user is currently in an unhealthy state.

[0093] Furthermore, when the temperature of the finger is within a preset temperature range, the electronic device can be controlled to play voice information indicating that the user is currently in a healthy state, and / or display graphic information indicating that the user is currently in a healthy state, or the electronic device can be controlled not to respond to the result that the temperature of the finger is within a preset temperature range.

[0094] Figure 4 is a flowchart of an example of a temperature detection method provided according to an embodiment of the present disclosure.

[0095] like Figure 4 As shown, the temperature detection method may include the following steps:

[0096] Step S4001, receiving a fingerprint unlocking operation triggered by a finger in a fingerprint input area, obtaining the fingerprint of the finger, multiple sampling temperatures of a first detection point in a first period of time, and multiple sampling temperatures of a second detection point in the first period of time.

[0097] Step S4002, determining a first stable temperature of the first detection point according to a plurality of sampled temperatures of the first detection point in a first time period; and determining a second stable temperature of the second detection point according to a plurality of sampled temperatures of the second detection point in the first time period.

[0098] Step S4003, determining a stable temperature of the target position according to a first distance between the first detection point and the target position in the fingerprint input area, a second distance between the second detection point and the target position, the first stable temperature, and the second stable temperature.

[0099] Step S4004, determining the temperature of the finger applied to the target position according to the stable temperature of the target position.

[0100] Step S4005, determine whether the temperature of the finger is within a preset temperature range, if yes, execute step S4006; if no, end.

[0101] Step S4006: Match the acquired fingerprint of the finger with the pre-stored fingerprint.

[0102] Figure 5 is a flowchart of an example of a temperature detection method provided according to an embodiment of the present disclosure.

[0103] like Figure 5 As shown, the temperature detection method may include the following steps:

[0104] Step S5001, receiving a fingerprint unlocking operation triggered by a finger in a fingerprint input area, obtaining the fingerprint of the finger, multiple sampling temperatures of a first detection point in a first period of time, and multiple sampling temperatures of a second detection point in the first period of time.

[0105] Step S5002, determining a first stable temperature of the first detection point according to a plurality of sampled temperatures of the first detection point in a first time period; and determining a second stable temperature of the second detection point according to a plurality of sampled temperatures of the second detection point in the first time period.

[0106] Step S5003, determining the stable temperature of the target position according to the first distance between the first detection point and the target position in the fingerprint input area, the second distance between the second detection point and the target position, the first stable temperature and the second stable temperature.

[0107] Step S5004, determining the temperature of the finger applied to the target position according to the stable temperature of the target position.

[0108] Step S5005: Match the acquired fingerprint of the finger with the pre-stored fingerprint.

[0109] Step S5006: When the fingerprint of the finger matches the pre-stored fingerprint, the electronic device is controlled to unlock.

[0110] Step S5007, monitoring the user's health based on the temperature of the finger.
