Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control system of a terminal device, a control method of a terminal device, and a terminal device according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a block schematic diagram of a control system of a terminal device according to one embodiment of the present invention. As shown in fig. 1, the control system includes: the device comprises an ambient light sensor 1, a false touch prevention module 2 and a power management unit 3.
Wherein, the ambient light sensor 1 is used for generating a first interrupt pulse signal when detecting that the ambient light sensor is shielded; the false touch prevention module 2 is used for counting according to the number of the received first interrupt pulse signals, and generating a starting trigger signal when the counting value reaches a set number threshold value within set time; the power management unit 3 is configured to supply power to the corresponding component 5 after receiving the power-on trigger signal, so as to control the terminal device to be powered on.
Specifically, the ambient light sensor 1 may sense the ambient light intensity, and detect whether itself is blocked according to the ambient light intensity, wherein if it is sensed that the magnitude of the decrease in the ambient light intensity exceeds a preset value, it may be determined that itself is blocked. When the environmental sensor 1 detects that the environmental sensor is shielded, a first interrupt pulse signal is generated and sent to the false touch prevention module 2, and a counting register in the false touch prevention module 2 counts the number of the first interrupt pulse signal. If the count value reaches the threshold value of the preset number prestored in the threshold value register in the false touch prevention module 2 within the set time, a Power-on trigger signal is generated and sent to a Power Management Unit (PMU) 3. That is, if the ambient light sensor 1 detects that the number of times of shielding itself within the preset time reaches the set number threshold, it becomes the power-on trigger signal.
The power management unit 3 is started after receiving the startup trigger signal, and outputs a plurality of paths of constant voltage power supplies with certain driving capability to supply power for corresponding components and control the terminal equipment to be started. From this, this control system utilizes ambient light sensor's sensitization function to realize the terminal equipment start, and the cost is lower and be applicable to all kinds of terminal equipment, and need not to carry out dustproof and waterproof and frame trompil, when being applied to small-size mobile terminal, can guarantee complete machine equipment wholeness, promotes structural design's flexibility to can save space, thereby increase antenna layout space, improve antenna efficiency.
In order to prevent the false triggering of the startup, for example, a user only carelessly shields the ambient light sensor and does not want to start the computer, the set number threshold may be an integer greater than 1, and in order to avoid causing the startup operation to be cumbersome, the set number threshold should not be too much, and the set number threshold may be 3-5. The setting time is not suitable for being too long, otherwise misoperation is easily caused, the setting time is not too short, otherwise operation difficulty is possibly caused, and the setting time can be 3-7 seconds.
The setting position of the ambient light sensor 1 should be a place convenient for the user to touch, for example, if the mobile terminal is used, the ambient light sensor 1 may be a middle part or a part above the middle part of the back of the mobile terminal, so as to facilitate the user to operate with one hand, or may be set in the front of the mobile terminal, but should be far away from the HOME key, so as to avoid misoperation. The position where the ambient light sensor 1 is disposed is not limited in the present invention.
According to an embodiment of the present invention, as shown in fig. 2, the terminal device described above may further include: a proximity photosensor 4 for generating a second interrupt pulse signal when detecting that itself is occluded; the false touch prevention module 2 is further configured to count according to the number of the received second interrupt pulse signals, and generate a startup trigger signal when the count value reaches a set number threshold within a set time.
Specifically, if the terminal device is in an extremely dark environment, when the environmental sensor 1 is shielded, the environmental sensor 1 may not detect that the terminal device is shielded due to small variation of the light intensity of the surrounding environment, so that the terminal device cannot be turned on. To avoid such a situation, the present invention also provides a proximity light sensor 3 in the control system of the terminal device. The proximity optical sensor 3 includes an optical transmitter and an optical receiver, the optical transmitter may transmit infrared light at a first preset distance, if the distance between the object and the proximity optical sensor 3 is less than the first preset distance (for example, 1cm), the infrared light may be reflected to the optical receiver, when the optical receiver receives the reflected light, the proximity optical sensor 3 determines that itself is blocked, and generates a second interrupt pulse signal, and transmits the second interrupt pulse signal to the anti-false-touch module 2, and the anti-false-touch module 2 counts the number of the second interrupt pulse signals. If the count value reaches the threshold value of the set number within the set time, a startup trigger signal is generated and sent to the power management unit 3. That is, if the proximity light sensor 3 detects that the number of times of shielding itself reaches the set number threshold within the preset time, it becomes the power-on trigger signal. Therefore, the environment light sensor and the proximity light sensor carry out double detection, and the starting trigger signal is generated when the corresponding interrupt pulse signal generated by any one sensor reaches the threshold value of the set number within the preset time, so that the condition that the starting trigger signal cannot be generated due to environmental reasons or the fault of one sensor is avoided, and the working reliability of the control system is improved.
In the invention, the battery can directly supply power to the false touch prevention module 2, the ambient light sensor 1, the proximity light sensor 4 and the battery management unit 3, so that the control system cannot be powered off after being shut down.
According to an embodiment of the present invention, the false touch prevention module 2 may further be configured to: and when the count value in the set time does not reach the set number threshold value, resetting the count value in the false touch prevention module 2.
Specifically, if the false touch prevention module 2 determines that the first interrupt pulse signal and the second interrupt pulse signal do not reach the threshold of the set number within the set time, it may be a user misoperation, or may be another reason, such as only receiving the terminal device into a bag or a pocket, which causes the interrupt pulse signal to occur, and does not want to shut down, and at this time, the false touch prevention module 2 clears the count value to perform initialization.
According to an embodiment of the present invention, as shown in fig. 2, the corresponding component 5 includes a Central Processing Unit (CPU) 501, a Radio Frequency Integrated Circuit (RFIC)502 and a peripheral port 503, and the Central Processing unit 501 is further configured to: and after the terminal equipment is started, outputting a closing enabling signal to the false touch prevention module so as to close the false touch prevention module and clear the counting value of the false touch prevention module.
The central processor 501 is further configured to: after the terminal equipment is started, the terminal equipment is communicated with the ambient light sensor, and the screen brightness is adjusted according to light intensity data collected by the ambient light sensor.
Specifically, after receiving the power-on trigger signal, the power management unit 3 controls the battery to supply power to the central processing unit 501, the radio frequency integrated circuit 502, and the peripheral port 503, so as to control the terminal device to be powered on. After the terminal device is turned on, the central processing unit 501 outputs a shutdown enable signal (an enable signal inverse level) to the false touch prevention module 2 to shut down the false touch prevention module 2, and clears a count value in the false touch prevention module 2 to perform initialization. Moreover, after the end device is started, the central processing unit 501 is also in communication with the ambient light sensor 1, and adjusts the screen brightness according to the light intensity data collected by the ambient light sensor 1, so that the screen can provide soft pictures, and when the ambient brightness is high, the central processing unit 501 automatically adjusts the display screen to high brightness according to the light intensity data collected by the ambient light sensor; when the external environment is dark, the central processing unit 501 automatically adjusts the display screen to low brightness according to the light intensity data collected by the ambient light sensor.
According to an embodiment of the invention, the power management unit 3 may further be configured to: and after receiving the shutdown trigger signal, controlling the battery to stop supplying power to the corresponding component so as to control the terminal equipment to shut down.
The central processor 501 may also be used to: after the terminal device is turned off, the communication with the ambient light sensor 1 is disconnected. After the terminal device is powered off, the central processing unit 501 outputs a start-up enabling signal to the false touch prevention module 2 to start the false touch prevention module 2.
Specifically, the shutdown may be implemented by software, the software sends a shutdown trigger signal to the power management unit 3 and the central processing unit 501, and after receiving the shutdown trigger signal, the power management unit 3 controls the battery to stop supplying power to the corresponding component 5, so as to control the terminal device to shutdown. After the terminal device is powered off, the central processing unit 501 disconnects the communication with the ambient light sensor 1, so that the central processing unit 501 stops adjusting the screen brightness, and outputs a start enabling signal to the false touch prevention module 2 to start the false touch prevention module 2, and the false touch prevention module 2 judges whether to generate a start triggering signal according to a first interrupt pulse signal detected by the ambient light sensor 1 and a second interrupt pulse signal detected by the proximity light sensor 4.
In order to make the present invention more clearly understood by those skilled in the art, the following description is made with reference to an operational principle flowchart of a control system of a terminal device according to one specific example of the present invention shown in fig. 3. As shown in fig. 3, the operation principle of the control system of the terminal device of the present invention includes the following steps:

And S109, the false touch prevention module clears the corresponding count value and returns to the step S101.
And S110, the power management unit supplies power to the central processing unit, the radio frequency integrated circuit and the peripheral port so as to control the terminal equipment to be started.
And S111, the central processing unit outputs a closing enable signal to the false touch prevention module so as to close the false touch prevention module, and the false touch prevention module clears the count value.

It can be understood that, before the terminal device leaves the factory, the booting method can be written in the corresponding specification to inform the user how to perform the booting operation, and how many times, areas, time, and the like need to be blocked, so that the user can perform the booting operation.

Specifically, the ambient light sensor can perceive the ambient light intensity and detect whether the ambient light intensity is shielded or not according to the ambient light intensity, wherein if the ambient light intensity is perceived to be reduced by an amplitude exceeding a preset value, the ambient light sensor can judge that the ambient light intensity is shielded. When the environmental sensor detects that the environmental sensor is shielded, a first interrupt pulse signal is generated and sent to the false touch prevention module, and a counting register in the false touch prevention module counts the number of the first interrupt pulse signal.
