Embodiment Construction

[0020] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] figure 1 Shows the scheme block diagram that the embodiment of the present invention provides, as figure 1 shown, including:

[0022] The power analog switch has an enable terminal that controls the on-off of the analog switch. The input signal of the enable terminal is provided by the hardware watchdog, that is, the output signal of the hardware watchdog is used as the input signal of the enable terminal of the power analog switch. When the mobile phone is working normally, the output signal of the hardware watchdog is high level, the analog switch is in the closed state, and the battery voltage VBAT1 normally supplies power to the baseband and R...

Abstract

The invention discloses a crash auto-restart method and a mobile phone. The method comprises the following steps that: a base band and radio-frequency amplification module outputs a watchdog clearing signal to hardware watchdog; the hardware watchdog outputs a reset signal to an enabling end of a power analog switch when the hardware watchdog does not receive a watchdog clearing signal within a certain period of time; and the enabling end of the power analog switch receives the reset signal which is output by the hardware watchdog to restart the mobile phone automatically. The crash auto-restart method and the mobile phone can improve customer satisfaction, improve market competiveness of the product and save implicit cost.

Description

technical field [0001] The invention relates to the field of mobile phone communication, in particular to a method for automatically restarting a dead machine and a mobile phone. Background technique [0002] With the rich and diverse functions of mobile phones, especially the wide application of smart phones, the complexity of its software processing flow is increasing day by day. If a large number of concurrent software processes cannot be processed in a timely and effective manner, the system may crash and crash. At this time, the user can only manually lift the battery cover to cut off the battery, and then connect the battery to restart the mobile phone. [0003] The mobile phone system generally integrates a watchdog function. The so-called watchdog is actually a timer. It is used to monitor the running status of the internal program of the mobile phone system. It can automatically reset when the program runs away or is locked. design. The working principle of the wa...
