Detailed Description
In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a dark screen standby method based on an android operating system, which comprises the following steps with reference to fig. 1:
step S1, adding a dark screen standby option in a setting menu of the operating system, wherein the dark screen standby option can be switched on or off;
storing the configuration information of the on or off of the dark screen standby option in a system database;
step S2, monitoring the state of the equipment in real time, triggering a screen-off timer to start timing immediately after monitoring that the equipment is not operated, and entering a screen-off process of the system when the duration time of the equipment which is obtained by timing and is not operated reaches a preset time length T, namely: step S3 is executed;
step S3, the system screen-off process:
step S3.1, performing dark screen processing on the equipment to enable the equipment to enter a dark screen state, namely: adjusting the screen brightness of the equipment to the minimum;
s3.2, reading a system database to obtain configuration information for opening or closing the dark screen standby option; if the hidden screen standby option is on, executing step S3.3; if the dark screen standby option is closed, executing step S3.5;
step S3.3, calling a system power management interface, reading the charging state of the equipment, and executing step S3.4 if the equipment is in the charging state; if the device is in an uncharged state, performing step S3.5;
in this step, the charging state of the device is obtained by detecting whether the device is connected to the charging adapter.
S3.4, keeping the equipment in a dark screen standby state; in the dark screen standby state, if the screen is detected to be touched, the equipment is awakened, the dark screen standby state is released, the brightness of the screen is recovered, the user operation can be carried out, and then the step S2 is returned; in the dark screen standby state, if it is detected that the device is manually locked, step S3.5 is performed;
s3.5, locking the system to extinguish the screen, so that the system enters a screen extinguishing state; until it is detected that the device is manually unlocked, the screen is brightened, user operation is possible, and then the process returns to step S2.
The invention provides a hidden screen standby method based on an android operating system, which mainly comprises the following steps:
when the duration of the non-operation of the equipment reaches the preset time length, firstly, the brightness of the screen of the equipment is adjusted to the minimum, then, when the dark screen standby option is started and the equipment is in a charging state, the equipment is kept in a dark screen standby state, and the screen is not locked at the moment, so that the equipment can be conveniently awakened when the screen is touched in the dark screen standby state, the brightness of the screen is recovered, and the operation of a user can be carried out. And when the hidden screen standby option is not started or the hidden screen standby option is started but the equipment is in a non-charging state, the screen is turned off, and the system is locked. At this time, the screen can be restored to brightness only by manually unlocking the screen, and user operation can be performed.
The principle of the method is as follows: for the intelligent POS used by the merchant, in practical applications, the intelligent POS is usually in a charging state, that is: intelligence POS machine and power connection state, this kind of state need not have strict requirement to the electric quantity, so, for convenience of customers uses, practices thrift operating time, and when equipment does not have the operation duration longer, for practicing thrift the electric energy, makes equipment screen brightness transfer to minimumly, promptly: and entering a dark screen standby state, but not locking the screen so as to avoid the user from repeating the locking and unlocking steps. When the dark screen standby option is turned on but the device is in an uncharged state, the device needs to be in an uncharged state, so that the service time of the device needs to be prolonged as much as possible, the power consumption of the device needs to be reduced, and therefore, the screen needs to be completely turned off, and the system needs to be locked.
Compared with the traditional mode of repeatedly locking and unlocking the equipment, the hidden screen standby method based on the android operating system can save the operating time and reduce the power consumption to a certain extent. Compared with the mode that the equipment is in a normally bright screen state, the power consumption of the equipment can be reduced by the aid of the function of the power supply device, and the power supply device is more secret. Therefore, the invention is a method compatible with saving operation time and reducing equipment power consumption, and meets the use requirements of intelligent POS machine users.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements should also be considered within the scope of the present invention.
