This anti-misoperation method generally uses a Proximity Sensor to sense whether the user is close to the mobile phone. However, this method does not recognize whether the human body is close to the real thing. For example, when the mobile phone is in the process of talking, the screen of the mobile phone is also locked when the mobile phone is close to the wall. Obviously, using a proximity sensor to sense whether the user is close to the phone cannot tell if the human body is close to the phone.

Figure 4 is a diagram illustrating the position of an infrared temperature sensor.

As shown in FIG. 1, it is an operating environment diagram of the smart lock screen system of the present invention. In this embodiment, the smart lock screen system 10 is operated in the mobile phone 1. The smart lock screen system 10 is used to activate the infrared temperature sensor 20 in the mobile phone 1 to sense the user when the mobile phone 1 is in a call state. The body temperature value is determined according to the body temperature value sensed by the infrared temperature sensor 20 to determine whether the user is close to the mobile phone 1, and then locks when the user approaches the mobile phone 1. The screen 30 of the mobile phone 1 is set to prevent the user from operating the mobile phone 1 by mistake.

In this embodiment, the smart lock screen system 10 can turn on the infrared temperature sensor 20 through a 12C bus or a GPIO (General Purpose Input Output) line. The screen 30 can be a multi-touch panel that supports multi-touch, such as a resistive touch screen or a capacitive touch screen.

In this embodiment, the infrared temperature sensor 20 can be disposed at a position close to the earpiece 40 of the mobile phone 1 to better sense the user's body temperature value when the mobile phone 1 is in a call state (refer to FIG. 4 Show). In other embodiments, the infrared temperature sensor 20 can also be disposed at other locations on the front of the handset 1, such as near a keyboard.

The infrared temperature sensor 20 can be an active infrared temperature sensor or a passive infrared temperature sensor. The active infrared temperature sensor performs body temperature sensing by actively emitting infrared rays and receiving infrared rays reflected by a user, and the passive infrared temperature sensor performs body temperature sensing by receiving infrared rays emitted by a user.

Specifically, in order to prevent the infrared temperature sensor 20 from being subjected to user body temperature sensing, the sensed user body temperature value error is large due to environmental influences (eg, environmental temperature difference, etc.), and the infrared temperature sense is large. The detector 20 is preferably a temperature sensor that can perform temperature compensation processing, that is, the infrared temperature sensor 20 can perform temperature compensation processing on the sensed user body temperature value according to the temperature value of the environment in which the mobile phone 1 is located.

Further, since the passive infrared temperature sensor only receives infrared rays emitted by the human body or the animal body, it is more realistic to judge that the screen 30 is locked when the user approaches the mobile phone 1. In this embodiment, the infrared temperature sensing is performed. The device 20 is preferably a passive infrared temperature sensor. The passive infrared temperature sensor can also perform temperature compensation processing on the sensed user body temperature value according to the temperature value of the environment in which the mobile phone 1 is located.

In this embodiment, the smart lock screen system 10 can be divided into one or more modules, and the one or more modules are stored in the memory 50 and executed by the processor 60 to complete the present The functionality provided by the invention. For example, as shown in FIG. 2 , the smart lock screen system 10 is divided into a set module 11 , an open module 12 , an acquisition module 13 , a determination module 14 , a lock module 15 , and an unlock module 16 . The module referred to in the present invention is a program segment for performing a specific function, and the functions of each module will be specifically described in the flowchart of FIG.

3 is a flow chart of a preferred embodiment of the smart lock screen method of the present invention.

In step S1, the setting module 11 presets the body temperature range according to the needs of the user. For example, the user can set the body temperature range from 36 ° C to 40 ° C according to his or her physical condition.

In step S2, when the mobile phone 1 is in the call state, the opening module 12 turns on the infrared temperature sensor 20 through the I2C bus bar, so that the infrared temperature sensor 20 instantly senses the user's body temperature when the mobile phone 1 is in a call state. It should be noted that, in other embodiments, the opening module 12 can also turn on the infrared temperature sensor 20 by other means, for example, through a GPIO (General Purpose Input Output) line. The acquisition module 13 acquires the user's body temperature value sensed by the infrared temperature sensor 20.

This embodiment is exemplified by the infrared temperature sensor 20 being a passive infrared temperature sensor. When the mobile phone 1 is in a call state, if the user is far away from the earpiece 40, the infrared ray emitted by the user received by the infrared temperature sensor 20 is weak, and the user's body temperature value sensed by the infrared temperature sensor 20 is detected. If the user is closer to the earpiece 40, the infrared temperature emitted by the infrared temperature sensor 20 is stronger, and the user's body temperature value sensed by the infrared temperature sensor 20 will be Closer to the user's actual body temperature. For example, the infrared temperature sensor 20 senses that the user's body temperature value is 37.5 °C.

In other embodiments, the infrared temperature sensor 20 can also be an active infrared temperature sensor. When the mobile phone 1 is in a call state, if the user is far away from the earpiece 40, the infrared light reflected by the user received by the active infrared temperature sensor is weak, and then the active infrared temperature sensor senses The user's body temperature value will be lower. Conversely, if the user is closer to the earpiece 40, the infrared radiation reflected by the user received by the active infrared temperature sensor is stronger, then the active infrared temperature sensor senses The measured user's body temperature value will be closer to the user's actual body temperature.

It should be noted that if the infrared temperature sensor 20 can perform temperature compensation processing, the user body temperature value acquired by the acquisition module 13 herein is the user body temperature value after the temperature compensation process.

In addition, it should be noted that the user can set the body temperature range according to whether the infrared temperature sensor 20 can perform temperature compensation processing, for example, if the infrared temperature sensor 20 can perform temperature compensation processing, then the user The body temperature range can be set closer to the user's actual body temperature.

In step S3, the determining module 14 determines whether the sensed user body temperature value is within the preset body temperature range. If yes, step S4 is performed; otherwise, the process returns to step S2 to continue to acquire the sensed by the infrared temperature sensor 20. User temperature value.

For example, the determining module 14 determines that the obtained user's body temperature value is 37.5 ° C within a preset body temperature range (36 ° C to 40 ° C), that is, the user is determined to be very close to the mobile phone 1 . S4.

In step S4, the locking module 15 locks the screen 30 to prevent the user from operating the phone 1 by mistake.

Step S5, if the user really needs to operate the mobile phone 1 during the call, for example, If the user wants to find out a contact phone stored in the mobile phone 1 to inform the other party during the call, the user will generally move the mobile phone 1 to the front of the mobile phone to use it. In the earpiece 40, the user's body temperature value sensed by the infrared temperature sensor 20 is reduced. For example, the acquisition module 13 acquires the user's body temperature value sensed by the infrared temperature sensor 20, which is 30 ° C. The judging module 14 further determines whether the obtained user's body temperature value is within the preset body temperature range. If not, the user is determined to be far from the earpiece 40. At this time, step S6 is performed, and if so, the user is still away from the earpiece 40. Nearly, the flow is ended at this time, that is, the mobile phone 1 still maintains the locked state of the screen 30.

In step S6, the unlocking module 16 releases the locked state of the screen 30. That is, the user can directly operate the mobile phone 1 without manually unlocking the screen 30.

It should be noted that, in step S1, the user can set the body temperature range according to specific needs. Specifically, if the user wishes to be far away from the earpiece 40, the mobile phone 1 is locked to ensure that the call is not mishandled during the call. In the mobile phone 1, the user can set the minimum value of the body temperature range to be small, for example, the body temperature range is set to 30 ° C to 40 ° C. The screen 30 of the mobile phone 1 can be locked when the user is still far from the earpiece 40.

As can be seen from the flow steps of the present invention, the present invention provides an infrared temperature sensor 20 disposed beside the earpiece 40 to sense the user's use when the mobile phone 1 is in a call state. The body temperature value, and then the screen 30 of the mobile phone 1 is locked according to the sensed user body temperature value to prevent the user from operating the mobile phone 1 by mistake during the call.

Since the present invention determines whether to lock the screen 30 according to the user's body temperature value, on the one hand, it can be ensured that the screen 30 is locked when the user approaches the mobile phone 1, and on the other hand, if the mobile phone 1 is in a call state, if the screen 30 is locked And the user does need to operate The mobile phone 1 can also cancel the screen lock state of the mobile phone 1 according to the obtained user body temperature value, thereby eliminating the user manual unlocking operation step, enhancing the user experience, and more convenient for the user to the mobile phone 1 use.

The above embodiments are only used to illustrate the technical solutions of the present invention, and the present invention is not limited thereto. The present invention will be described in detail with reference to the preferred embodiments, and those skilled in the art should understand that the technical solutions of the present invention may be modified or substituted. Without departing from the spirit and scope of the technical solutions of the present invention.
