Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the method for setting a clock based on an SIM module according to a preferred embodiment of the present invention includes the following steps:
and step S10, detecting the battery power, and judging whether the battery power is larger than a preset upper limit or smaller than a preset lower limit.
Specifically, a preset upper limit and a preset lower limit of the battery power are preset; and acquiring the electric quantity of the battery, and judging whether the acquired electric quantity of the battery is greater than the preset upper limit or less than the preset lower limit.
Considering that the mobile terminal is mostly powered by a rechargeable battery, the capacity of the battery to output voltage is often closely related to the remaining capacity of the battery, and generally, the preset upper limit is 80% -90%; the preset lower limit is 20-30%; when the battery power is high, the output voltage may be slightly too large, and when the battery power is low, the output voltage may be slightly too small; the above is disadvantageous to the stability of the clock signal of the SIM module.
And step S20, if yes, setting the clock power supply of the SIM module as default current configuration when the mobile terminal is detected to be powered on.
Specifically, when the battery power is judged to be greater than a preset upper limit or less than a preset lower limit, whether the mobile terminal is enabled to be connected with the SIM module is detected; and if so, acquiring the default current configuration of the SIM module, and setting the clock power supply of the SIM module as the default current configuration.
Wherein the obtaining the default current configuration of the SIM module comprises: acquiring the current electric quantity of the electric battery; searching the current configuration of the last SIM module corresponding to the electric quantity of the battery; the SIM module current configuration is a SIM module default current configuration.
Based on the above steps, the configuration needs to be saved each time the SIM module clock configuration is completed, so that the configuration is used as the default configuration when the same power needs to be configured next time.
If the battery power is judged to be not more than the preset upper limit or less than the preset lower limit, no processing is needed; when the battery capacity is in the middle section, the power supply is stable and can not be processed.
Step S30, detecting a positive voltage and a negative voltage of the clock signal of the SIM module, determining whether the maximum voltage is within a first preset range, and simultaneously determining whether the minimum voltage is within a second preset range.
Specifically, a first preset range and a second preset range of voltage are preset; detecting the positive voltage and the negative voltage of a clock signal of the SIM module; and judging whether the maximum voltage of the detected clock signal is within the first preset range or not, and simultaneously judging whether the minimum voltage of the detected clock signal is within the second preset range or not.
And step S40, if the result is no, setting the clock power supply current of the SIM module as the preset multiple of the currently set clock power supply current configuration of the SIM module.
Specifically, when the detected maximum voltage of the clock signal is not within the first preset range and the detected minimum voltage of the clock signal is not within the second preset range, acquiring a currently set clock supply current configuration of the SIM module; setting the clock supply current of the SIM module to be 1.05 times of the currently set clock supply current configuration of the SIM module until the detected maximum voltage of the clock signal is within the first preset range and the detected minimum voltage of the clock signal is within the second preset range.
That is, after the configuration of the clock supply current of the SIM module is set, the process returns to step S30 until the detected maximum voltage of the clock signal is within the first preset range and the detected minimum voltage of the clock signal is within the second preset range.
