Description

Automatic switch machine scheduling control method and system

technical field

The present invention relates to a system and its control method, in particular to a system with automatic on-off schedule and its automatic on-off schedule control method.

Background technique

In current electronic devices, many of the same components as personal computers are generally integrated, such as motherboard (Mother Board), random access memory (Random Access Memory; RAM), basic input output system (Basic Input Output System; BIOS) and even network card etc.

Because many times, the user cannot perform the action of starting the electronic device at a certain point of time due to reasons such as having to leave, so as to allow the electronic device to execute the booting procedure. However, if the user executes the power-on action on the electronic device first, it may cause problems such as idle operation of the electronic device and power consumption. Similarly, in many cases, the user has to leave and other reasons, but some program is running on the electronic device and cannot be shut down immediately, so the electronic device can only be turned on continuously.

In order to prevent the user from being unable to perform the boot-up or shutdown action at the moment, the Basic I/O System (BIOS) of the electronic device provides a wake-up mechanism so that the user can set when the electronic device executes the boot-up procedure. There are various wake-up mechanisms, such as Resume On Ring, Wake On LAN, and Wakeup On Ring. Many software running in the electronic device can provide scheduled shutdown time, etc., so that the user can set when to let the electronic device execute the shutdown procedure.

However, the basic input and output system of the electronic device only provides one wake-up mechanism setting, and cannot provide multiple wake-up mechanism settings at different times. And the running software in the electronic device can only provide the scheduled shutdown setting of the current time, but cannot provide the scheduled shutdown settings of multiple different times. Neither the basic input and output system of the electronic device nor the operating program in the electronic device can provide the scheduling control of the automatic power on and off of the electronic device multiple times.

Contents of the invention

The present invention provides a system with automatic power on and off scheduling and its automatic power on and off scheduling control method, which can avoid the automatic power off of the electronic device only once through the application program or through the basic input and output system (Basic I/O) O System, BIOS) to complete one automatic power-on, but cannot achieve the scheduling control of multiple system automatic power-on and power-off.

The automatic power on/off scheduling control method of the system according to the present invention is applied to an electronic device. The automatic power-on/off schedule control method of the system includes: firstly, turning on the system power of the electronic device to execute the boot-up procedure of the electronic device (step 1); then, searching for the setting data of the automatic power-on/off (step 2); and then, when After reading the setting data with automatic power on and off, start a periodic interrupt (Periodic Interrupt) (step three); then, complete the booting procedure of the electronic device (step four); then, read the setting of automatic power on and off Shutdown time in the data (step 5); use periodic interruption to check the system time of the electronic device, and compare the system time with the read shutdown time (step 6); wherein, when the system time matches the shutdown time, set Next boot time (step seven); then, detect the operating system of the advanced configuration and power interface management device (Advanced Configuration and Power Interface, ACPI) (step eight); and when the operating system of the advanced configuration and power interface management device is in In the execution state, the operating system of the advanced configuration and power interface management device executes the shutdown procedure of the electronic device (step 9).

Among them, the setting data of each group of switching time is stored in the setting storage device, such as: complementary metal-oxide layer-semiconductor, non-volatile memory (Non-Volatile Random Access Memory, NVRAM), flash memory (Flash disk ) or hard disk (Hard Disk, HD), etc.

Wherein, in step five, the current system time is read from the setting storage device.

Among them, the setting of the next boot time in step 7 is mainly to set the next boot time of the system in the setting storage device, and the steps include: clearing the warning label (Alarm Flag); setting the wakeup time (wakeup time); enabling Alarm interrupt (alarm interrupt); clear I/O buffer records; and enable alarm wakeup events.

Wherein, step eight first searches for an advanced configuration and power interface management device flag, and when the advanced configuration and power interface management device flag is activated, it is determined that the operating system of the advanced configuration and power interface management device is in the execution state.

Step nine is to return to and execute step five when the operating system of the advanced configuration and power interface management device is not in execution state. In step 9, when the operating system of the advanced configuration and power interface management device does not exist, the shutdown procedure of the electronic device is executed by a legacy operating system. That is, the user or the processing module can write a soft off command to the port of the advanced configuration and power interface management device to execute the shutdown procedure of the electronic device.

According to the automatic power-on/off schedule control method of the system of the present invention, it further includes: checking the system time of the electronic device and comparing the system time with the next power-on time in the setting data of the automatic power-on/off machine (step ten); and when the system If the time matches the next power-on time, go back and execute step 1 (step 11).

The system with automatic power-on and power-off scheduling disclosed in the present invention can be applied to electronic devices running an operating system. The system with automatic power on and off scheduling of the present invention includes: a substrate, a storage unit, a connection unit and an external device.

The substrate is located in the electronic device, and the storage unit is connected to the substrate.

The connection unit is located on the substrate and is electrically connected to the storage unit.

The external device is electrically connected to the connecting unit, and is used to change the setting of the basic input and output system to operate the automatic power-on and power-off scheduling control method of the system.

Wherein, the system with automatic power on and off schedule changes the setting of the basic input and output system in the storage unit by connecting the external device to the connection unit, so as to run the automatic power on and off schedule control method of the above system.

Here, the system with automatic on/off scheduling and its automatic on/off scheduling control method of the present invention achieve multiple times of system automatic on/off scheduling control through the firmware program, and can automatically Judging the power-on or power-off time, and when the set time is reached, the power-on or power-off action is executed, and it can be turned on or off automatically without the user operating the switch button.

Detailed ways

The flow of the automatic power on/off scheduling control method of the system according to the present invention can be divided into three parts in sequence: the first part, the second part and the third part. Among them, the first part is the start-up process of the automatic power-on and power-off scheduling control method of the system; the second part is from the process after power-on to the power-off process of the automatic power-on and power-off scheduling control method of the system; the third part is the automatic power-on and power-off scheduling control method of the system The process after shutting down of the program control method to the process of starting up next time.

FIG. 2 is a flow chart of the second part of the automatic power on/off schedule control method of the system according to the present invention. FIG. 3 is a flow chart of the third part of the automatic power on/off schedule control method of the system according to the present invention.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , the automatic power on/off scheduling control method of the system according to the present invention is applied to an electronic device. The automatic power-on/off schedule control method of the system includes: firstly, turning on the system power of the electronic device to execute the boot-up procedure of the electronic device (step 1); then, searching for the setting data of the automatic power-on/off (step 2); and then, when After reading the setting data with automatic power on and off, start a periodic interrupt (Periodic Interrupt) (step three); then, complete the booting procedure of the electronic device (step four); then, read the setting of automatic power on and off Shutdown time in the data (step 5); use periodic interruption to check the system time of the electronic device, and compare the system time with the read shutdown time (step 6); wherein, when the system time matches the shutdown time, set The next boot time (step seven); then, detect the operating system of the advanced configuration and power interface management device (Advanced Configuration and Power Interface, ACPI) (step eight); and when the operating system of the advanced configuration and power interface management device is in In the execution state, the operating system of the advanced configuration and power interface management device executes the shutdown procedure of the electronic device (step 9).

According to the automatic power on/off schedule control method of the system of the present invention, in step 1, the system power supply of the electronic device is first activated to execute the booting procedure of the electronic device, that is, to run the Basic I/O System (BIOS).

Wherein, the method for activating the electronic device can be achieved by turning on the power actuator (such as hardware devices such as a power switch and a power button), or by other means.

Since the basic input output system is the firmware used to manage the hardware in the electronic device, the BIOS is first activated after booting, and then it will perform a complete and thorough inspection and test on the equipment of the computer. Then, the second step is to search the setting data of the automatic switch, that is, the processing module of the electronic device searches for the setting data of each group of switch time of the automatic switch. The setting data of each group of switching time can be stored in the setting storage device. The setting storage device can be complementary metal-oxide layer-semiconductor (Complementary Metal-Oxide-Semiconductor, CMOS), non-volatile memory (Non-Volatile Random Access Memory, NVRAM), flash memory (Flash disk) or hard disk (HardDisk, HD) etc.

Step 3 is to start a periodic interrupt function after reading the setting data with automatic power on and off. Among them, the periodic interrupt depends on the difference between the hardware and the chipset, and you can choose to use the system management interrupt (System Management Interrupt, SMI), power management timer (Power Management Timer, PM timer) or serial interrupt request (Serial Interrupt Request) in the chipset. , Serial IRQ) and other functions to generate periodic system interrupts. The periodic system interrupts generated by the system management interrupt or power management timer in the chipset are used to check the system time and compare it with the automatic shutdown time set by the user.

Then, step 4 detects all hardware and system settings connected to the electronic device to complete the boot process.

Wherein, in step 2, if the processing module cannot search for the setting data of automatic power-on and off, then continue the original boot-up procedure (for example: detect all hardware and system settings connected to the electronic device) to complete the boot-up procedure (step 4 ), that is, if the setting data of automatic power-on/off cannot be searched in step 2, then proceed to step 4 directly.

Steps 1 to 4 can be the start-up process of the system's automatic on-off schedule control method of the present invention, that is, the first part of the flow of the system's automatic on-off schedule control method.

Next, in step five, the processing module reads the power-off time stored in the setting data of automatic power-off in the setting storage device.

Then, in step 6, the processing module constantly checks the system time of the electronic device through the periodic system interrupt function of the chipset, and the shutdown time (set by the user) read from the setting storage device with the processing module Automatic shutdown time) to confirm whether the system time is consistent with the read shutdown time.

When the system time in step 6 does not match the read shutdown time, then return to step 5, after the processing module re-reads the shutdown time stored in the setting data of the automatic power-off machine in the setting storage device , go to step 6 again to confirm whether the system time is consistent with the shutdown time read.

Wherein, in the step of checking the system time by the processing module through the periodic system interrupt function of the chipset, the processing module reads the current system time by setting the storage device.

When the system time in step 6 matches the read shutdown time, proceed to step 7 to set the next startup time.

Wherein, the step of setting the next boot time is to set the next boot time in the setting storage device. The steps to set the next boot time in the setting storage device are mainly to first clear the alarm flag (Alarm Flag), then set the wake-up time (RTC wakeup time), then enable the alarm interrupt (alarm interrupt), and then clear the input /Output buffer record, last enable alert wakeup event.

Wherein, step 5 to step 7 can be the process from the start-up process of the system's automatic on-off schedule control method to the process before shutdown in the system's automatic on-off schedule control method of the present invention, that is, the system's automatic on-off schedule The second part of the control method flow.

Then, in step eight, the processing module detects whether there is an operating system of Advanced Configuration and Power Interface (ACPI), that is, the processing module searches for the flag of Advanced Configuration and Power Interface (ACPI) enabled flag). Wherein, when the flag of the advanced configuration and power interface management device is activated, it is determined that the operating system of the advanced configuration and power interface management device is in the execution state.

In other words, when the system enters the Advanced Configuration and Power Interface (ACPI) operating system, it will fill the value of the advanced configuration and power interface management device into the system management interrupt command port (SMI command port) ), when the system management interrupt command port (SMI command port) is filled with advanced configuration and power interface management equipment to start, a flag will be recorded and stored in the storage unit for the processing module to determine whether there is currently an advanced configuration and power interface management device The power interface manages the operating system of the device.

However, when the operating system of the advanced configuration and power interface management device exists and is in an unexecuted state, return to and perform step five.

Therefore, in step 9, when the operating system of the advanced configuration and power interface management device exists and is in the execution state, the operating system of the advanced configuration and power interface management device executes the shutdown procedure of the electronic device.

In step 9, when the operating system of the advanced configuration and power interface management device does not exist, the traditional operating system executes the shutdown procedure of the electronic device. That is, the user or the processing module can write a soft off command to the port of the advanced configuration and power interface management device to execute the shutdown procedure of the electronic device.

According to the automatic power on/off scheduling control method of the system of the present invention, it further includes: checking the system time of the electronic device and comparing the system time with the next power-on time in the setting data of the automatic power on/off (step ten); and when the system If the time matches the next power-on time, go back and execute step 1 (step 11).

After the electronic device executes the shutdown procedure, it still needs a standby power supply to provide the operation of the internal processing module, chipset or configuration storage device. At this time, the clock chip (Real Time Clock, RTC) inside the electronic device will continue to work to maintain the correct system time with the help of rechargeable batteries or dry batteries and other power sources after the computer is turned off. Therefore, step ten is to continuously check the system time of the electronic device by the periodic system interrupt function of the chipset and compare the system time with the next power-on time in the setting data of the automatic power-on/off machine.

Finally, in step eleven, when the periodic system interrupt function of the chipset checks that the system time matches the next boot time, start the system power of the electronic device to execute the boot procedure of the electronic device, that is, go back and execute step one.

Among them, step 10 to step 11 can be the process from the shutdown process to the next startup process of the automatic shutdown schedule control method of the system in the system's automatic shutdown schedule control method of the present invention, that is, the automatic shutdown of the system. The third part of the flow of the power on and off schedule control method

Herein, in the automatic power-on/off schedule control method of the system, the user can set multiple sets of automatic power-on/off time, and check the system time by using the periodic system interrupt generated by the periodic system interrupt function of the chipset. When the system time reaches or exceeds the set automatic shutdown time, set the next startup time, and shut down directly after the setting is completed. After the next startup, the periodic system interrupt generated by restarting the chipset is used to check the system time and compare it with the next set of power-on and off times set by the user. The cycle is repeated continuously until all the set automatic power-on and power-off times are executed.

The automatic power-on/off scheduling control method of the system of the present invention achieves the scheduling control of the automatic power-on/off of the system multiple times through the firmware program, and can automatically judge the power-on or power-off time according to the user's setting, and when the setting is reached When the time is set, the power-on or power-off action is performed, and it can be turned on or off by itself without the user operating the switch button.
