The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for protecting a mobile terminal from booting according to a preferred embodiment of the present invention. The method comprises the following steps:
s100, when the mobile terminal is started, detecting a high-level ripple signal generated by a battery module, and dividing the high-level ripple signal into a plurality of high-level ripple signal blocks.
Specifically, the high-level ripple signal is generated when the electrical signal VBAT of the battery module configured in the mobile terminal is instantly and quickly powered on, so as to realize quick startup of the mobile terminal. The battery module may be a lithium battery, that is, the high-level ripple signal is generated when the electric signal VBAT of the lithium battery supplies power instantly and quickly.
In this embodiment, since the high-level ripple signal generated by the battery module of the mobile terminal at the moment of starting up the mobile terminal is changed, the high-level ripple signal can be dynamically detected in order to more accurately detect the high-level ripple signal. The dynamic detection is to divide the high-level ripple signal into n high-level ripple signal blocks, which are a high-level ripple signal block 1, a high-level ripple signal block 2, and a high-level ripple signal block n. That is, the high-level ripple signal is composed of a high-level ripple signal block 1, a high-level ripple signal block 2, a high-level ripple signal block 3, …, and a high-level ripple signal block n. In practical application, the high-level ripple signal can be equally divided into n high-level ripple signal blocks according to time; the high-level ripple signal may also be equally divided into n high-level ripple signal blocks in time in other manners, such as the n high-level ripple signal blocks are in an increasing arithmetic progression or a decreasing arithmetic progression.

Specifically, the acquiring of the maximum high-level ripple signal of each high-level ripple signal block refers to acquiring the maximum high-level ripple signals of n high-level ripple signal blocks constituting the high-level ripple signal, respectively. That is, the high-level ripple signals with the largest voltage value in the n high-level ripple signal blocks are obtained. In practical applications, a high-level detection unit may be provided, and the maximum high ripple signal in the high-level ripple signal block 1, the high-level ripple signal block 2, the high-level ripple signal block 3, …, and the high-level ripple signal block n is detected by the high-level detection unit. Comparing each maximum high ripple signal with a preset high level ripple signal; when a level signal greater than a preset high-level ripple signal exists, the high-level ripple signal block 1, the high-level ripple signal block 2, the high-level ripple signal block 3, …, the maximum high-level ripple signal 1, the maximum high-level ripple signal 2, the maximum high-level ripple signal 3, … and the maximum high-level ripple signal n are respectively output.
In this embodiment, the preset high-level ripple signal is a high-level ripple signal generated without affecting the power-on of the mobile terminal, and is set as the maximum voltage signal of the lithium battery power supply signal VBAT. Preferably, the voltage value of the preset high-level ripple signal is 4.35V.
And S300, filtering all the maximum high-level ripple signals to enable all the maximum high-level ripple signals to be less than or equal to the high-level ripple signals.
Specifically, the filtering all the maximum high-level ripple signals refers to filtering the maximum high-level ripple signals through a filtering unit and inputting first high-level ripple information respectively. That is, the maximum high-level ripple signal 1, the maximum high-level ripple signal 2, the maximum high-level ripple signal 3, …, and the maximum high-level ripple signal n are filtered to output the high-level ripple signal 11, the high-level ripple signal 22, the high-level ripple signal 33, …, and the high-level ripple signal nn.
Further, the high-level ripple signal 11, the high-level ripple signal 22, the high-level ripple signals 33, …, the maximum high-level ripple signal 11, the maximum high-level ripple signal 22, the maximum high-level ripple signals 33, …, and the maximum high-level ripple signal nn of the high-level ripple signal nn are detected, and are respectively compared with the preset high-level ripple signal, if the maximum high-level ripple signal greater than the preset high-level ripple signal exists, the filtering process is repeated until all the maximum high-level ripple signals are less than or equal to the high-level ripple signal.
In this embodiment, the filtering all the maximum high-level ripple signals so that all the maximum high-level ripple signals are less than or equal to the high-level ripple signals specifically includes:
s301, when the maximum high-level ripple signal is larger than a preset high-level ripple signal, outputting all the maximum high-level ripple information, and filtering all the maximum high-level ripple signals to obtain a first high-level ripple signal;
s302, detecting the maximum high-level ripple signals of all the first high-level ripple signals, and respectively comparing the maximum high-level ripple signals with preset high-level ripple signals;
and S303, when the maximum high-level ripple signal is larger than the preset high-level ripple signal, repeating the filtering and comparing operations until all the maximum high-level ripple signals are smaller than or equal to the high-level ripple signal.
In an embodiment of the present invention, the method for protecting power on of a mobile terminal may further include:
s400, stopping detecting the high-level ripple information generated by the battery module and controlling the mobile terminal to start.
Specifically, when all the maximum high-level ripple signals are less than or equal to the high-level ripple signals and are less than the preset high-level ripple signal, the detection of the high-level ripple information generated by the battery module is stopped, and the mobile terminal is controlled to be started. That is to say, when detecting the high-level ripple signal block 1, the high-level ripple signal block 2, the high-level ripple signal block 3, …, and all the maximum high-level ripple signals of the high-level ripple signal block n are less than or equal to the preset high-level ripple information (i.e., the maximum voltage signal 4.35V of the lithium battery power supply signal VBAT), the mobile terminal stops detecting the high-level ripple signal generated by the instant lithium battery power supply signal VBAT, and the mobile terminal is controlled to start normally.
