Embodiment 1

[0029] figure 1 It is a schematic structural diagram of the automatic power-on circuit provided by Embodiment 1 of the present invention.

[0030] refer to figure 1 , the automatic power-on circuit includes:

[0031] One end of the resistor R4 inputs the power supply voltage, and the other end of the resistor R4 is respectively connected to the general input and output port GPIO and the base of the transistor Q2, and the emitter of the transistor Q2 is respectively connected to one end of the resistor R2 and one end of the resistor R3, and the resistor R3 The other end is connected to the power supply voltage;

[0032] The other end of the resistor R2 is connected to the base of the transistor Q1, the collector of the transistor Q1 is respectively connected to one end of the resistor R1 and one end of the button, the emitter of the transistor Q1 is grounded, and the other end of the button is grounded.

[0033] In this embodiment, after the power is plugged in through the a...

Embodiment 2

[0050] figure 2 and image 3 It is a schematic diagram of the automatic boot device of the Android system provided by Embodiment 2 of the present invention.

[0051] refer to figure 2 and image 3 , the automatic boot device of the Android system, including the automatic boot circuit 10, and also includes the terminal 20 installed with the Android system.

[0052] One end of the button in the automatic power-on circuit 10 is connected with the terminal 20 .

[0053] The operation of the Android system in the terminal 20 is controlled by activating the keys in the automatic boot circuit 10 . The other end of the button is grounded.

[0054] When the button is pressed, the other end of the button is short-circuited to the ground, that is, the other end of the button is short-circuited to the ground once, that is, the button is pressed once.

[0055] The embodiment of the present invention provides an automatic power-on circuit and an automatic power-on device for an Andr...

Abstract

The invention provides an automatic boot circuit and an automatic boot device of an Android system, The automatic startup circuit comprises: A supply voltage is input to one end of resistor R4. the other end of the resistor R4 is respectively connected with the general-purpose input / output port GPIO and the base of the transistor Q2, the emitter of transistor Q2 is connected to one end of resistorR2 and one end of resistor R3, the other end of the resistor R3 is connected to the power supply voltage, the other end of the resistor R2 is connected to the base of the transistor Q1, the collectorof the transistor Q1 is connected to one end of the resistor R1 and one end of the key, The emitter of transistor Q1 is grounded, and the other end of the key is grounded. The automatic boot circuitis connected with the terminal installed with Android system, so that the automatic boot function can be realized and the user experience can be improved when the power system is cut off and the poweris restored.

Description

technical field [0001] The invention relates to the technical field of the Android system, in particular to an automatic boot circuit and an automatic boot device for the Android system. Background technique [0002] At present, for some terminals installed with the Android system, since these terminals are not equipped with batteries, when the power system is powered off and then powered on again, these terminals cannot restart automatically, and the Android system needs to be restarted manually. When the user cannot start it manually due to special reasons, it will affect the use of the terminal. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide an automatic power-on circuit and an automatic power-on device for the Android system, which can realize the function of automatic power-on when the power system is powered off and then powered on again, and improve user experience. [0004] In the first aspect, the embodiment...
