Method and apparatus for powering on a terminal
View Patent ↗A method and an apparatus for powering on a terminal. The method for powering on a terminal includes collecting, by a pressure detection sensor disposed inside a housing of a terminal, a value of pressure; sending, by the pressure detection sensor, an interrupt request to a power management unit (PMU) when the value of the pressure collected by the pressure detection sensor meets a set condition; and outputting, by the PMU, a power supply maintaining signal after receiving the interrupt request, so as to power on the terminal.
1. A method for powering on a terminal, comprising:
generating, by a pressure detection sensor of the terminal, a pressure value when a force is applied to the terminal;
sending, by the pressure detection sensor, to a power management device an interrupt request signal at a first time when the pressure value meets or exceeds a set condition;
continue sending, by the pressure detection sensor to the power management device, the interrupt request signal while the pressure value meets or exceeds the set condition;
waiting, by the power management device, a predetermined time during which the interrupt request signal is active until a second time; and
outputting, by the power management device, a power supply maintaining signal for supplying power to the terminal.
2. The method according to claim 1 , wherein the set condition comprises a preset pressure threshold value.
3. The method according to claim 1 , wherein the second time is equal to a preset minimum power-on time.
4. The method according to claim 3 , wherein the preset minimum power-on time is in a range of 500 milliseconds to 3 seconds.
5. An apparatus for powering on a terminal, comprising:
a housing;
a pressure detection sensor coupled to the housing, wherein the pressure detection sensor is configured to:
generate a pressure value when a force is applied to the housing;
send an interrupt request signal at a first time when the pressure value meets or exceeds a set condition; and
continue to send the interrupt request signal while the pressure value meets or exceeds the set condition; and
a power management component electrically connected to the pressure detection sensor, wherein the power management component is configured to:
wait a predetermined time during which the interrupt request signal is active until a second time; and
output a power supply maintaining signal for supplying power to the terminal.
6. The apparatus for powering on a terminal according to claim 5 , wherein the set condition comprises a preset threshold pressure value.
7. The apparatus for powering on a terminal according to claim 6 , wherein the second time is equal to a preset minimum power-on time.
8. The apparatus for powering on a terminal according to claim 7 , wherein the preset minimum power-on time is in a range of 500 milliseconds to 3 seconds.
9. The apparatus for powering on a terminal according to claim 5 , further comprising a protrusion part disposed on the housing, wherein the protrusion part is located between the housing and the pressure detection sensor, and wherein the protrusion part is in contact with the pressure detection sensor.
10. The apparatus for powering on a terminal according to claim 9 , wherein the protrusion part is arc-shaped.
11. The apparatus for powering on a terminal according to claim 5 , wherein the pressure detection sensor generates the pressure value while the terminal is powered-off.
12. A terminal, comprising:
a power management component; and
a pressure detection sensor coupled to the power management component and configured to:
generate a pressure value when a force is applied to the terminal;
send to the power management component an interrupt request signal at a first time when the pressure value exceeds a predetermined pressure threshold value; and
continue to send to the power management component the interrupt request signal for a duration while the pressure value meets or exceeds the predetermined pressure threshold value, wherein the power management component is configured to output a power supply maintaining signal when the duration is at least equal to a preset minimum power-on time.
13. The terminal according to claim 12 , wherein the preset minimum power-on time is 500 milliseconds to 3 seconds.
14. The terminal according to claim 12 , wherein the power management component is further configured to compare the duration with the preset minimum power-on time.
15. The terminal according to claim 12 , wherein the pressure detection sensor generates the pressure value while the terminal is powered-off.
