Problems solved by technology

However, most power management chips are customized for specific processors, and the switching mode is fixed; when the power is turned off, since the new power management chip is directly hung under the power line, there is still a leakage current of 50-100uA

Embodiment

[0033] This embodiment discloses a software self-locking key switch machine control system, which includes a key switch and a control module connected to the key switch. Wherein, the key switch is a tact switch, which is in an off state under normal conditions, and turns on after being pressed. The above-mentioned control module is used for customizing the on / off mode, and receiving the pressing signal of the above-mentioned key switch, and judging whether the above-mentioned pressing signal matches the on / off signal defined in the above-mentioned custom on / off mode; and, when the above-mentioned pressing signal matches the When the power-on signal matches, control to turn on the power supply; when the pressing signal matches the shutdown signal, control to turn off the power supply.

[0034] Custom on / off mode includes user setting according to their own needs, for example, long press for three seconds to turn on / off, or three consecutive short presses to turn on / off, or two-...

Embodiment 2

[0076] This embodiment discloses a software self-locking key switch control method, including the following steps,

[0077] The key switch generates a pressing signal;

[0078] The control module receives the above-mentioned pressing signal, judges whether the above-mentioned pressing signal matches the self-defined power-on / off signal, and controls to turn on the power supply when the above-mentioned pressing signal matches the above-mentioned power-on signal; when the above-mentioned pressing signal matches the above-mentioned power-off signal, controls Turn off the power supply.

[0079] Among them, in order to reduce the processing capacity of the processing unit and improve the operating efficiency of the system, the processing unit detects that it is currently in the power-on state, and judges whether the above-mentioned pressing signal matches the power-off signal; Does it match.

[0080] The implementation process of the above control method is the same as that of th...

Abstract

The invention discloses a software self-locking type key startup and shutdown control system and method. The system comprises a key switch and a control module connected with the key switch, and the control module is used for customizing an on / off mode, receiving a pressing signal of the key switch and judging whether the pressing signal is matched with the on / off signal defined in the custom on / off mode or not; when the pressing signal is matched with the startup signal, the power supply is controlled to be started; and when the pressing signal is matched with the shutdown signal, a step of controlling to turn off the power supply is performed. According to the software self-locking type key startup and shutdown control system and method, software of the control module is used for lockingand releasing power supply startup / shutdown signals of a system or equipment, software self-locking startup and shutdown are achieved, mistaken touch is prevented, and a user can flexibly define startup and shutdown modes according to actual conditions; on the other hand, compared with a traditional power supply management chip, no load exists after shutdown, and then zero power consumption of shutdown is achieved.

Description

technical field [0001] The invention relates to the technical field of switch machine control through a key switch, in particular to a software self-locking key switch control system and a software self-locking key switch control method. Background technique [0002] At present, toggle switches, rocker switches, and push button switches with self-locking functions are mostly used for switching on and off equipment. The current can be too large, and many devices are directly used to turn on and off the power supply. The on-off of the power supply controlled by mechanical means will bring a relatively large surge current at the moment of on-off, which will affect the safety and stability of the internal system operation of the equipment; moreover , The mechanical characteristics also restrict the flexibility of use, and it is easy to touch by mistake. [0003] With the further advancement of technology, tact switches (also known as "key switches") appear at this stage. Common...
