[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] Industrial computers are industrial control computers that have important computer properties and features, such as CPU, hard disk, memory, peripherals and interfaces, operating system, control network and protocol, computing power, etc. Industrial computers are intermediate products that provide safe, reliable and intelligent technical support for other industries and are important control equipment in the field of industrial automation.

[0040] However, due to the limitations of technical level and production process, the industrial control touch all-in-one computers on the market are mainly based on x86 architecture and embedded ARM chips. In some industrial control application fields, due to project security considerations, it is necessary to adopt an ARM architecture core platform. For example, Feiteng D2000 does not provide a timed power on and off function for energy-saving needs, which affects the application and widespread use of the ARM architecture core platform.

[0041] Based on this, the present application proposes a timed power on and off method and industrial computer based on an ARM architecture core processor, which can at least obtain the current time in real time from the RTC clock IC; according to the current time, the pre-set power on time and the pre-set power off time, the ARM architecture core processor is controlled to start or shut down, thereby realizing the timed power on and off function of the industrial computer based on the ARM platform, thereby improving the energy-saving capability and wide applicability of the ARM platform.

[0042] Referring to FIG. 1 , in an exemplary embodiment, a timed power on / off method based on an ARM architecture core processor is provided, comprising:

[0043] S101, obtaining the current time from the RTC clock IC in real time.

[0044] S102, controlling the industrial computer to start or shut down according to the current time, the preset start time and the preset shutdown time.

[0045] It should be noted that the timed power on / off method based on the ARM architecture core processor provided in this application is applied to industrial computers.

[0046] As an example, please refer to FIG. 4 . In an exemplary embodiment, an industrial computer is provided, including: an ARM architecture core processor 10 , a BIOS 20 , and an RTC clock IC 30 .

[0047] Among them, the RTC clock IC30 is used to output the current time to the BIOS20; the BIOS20 is used to obtain the current time from the RTC clock IC30 in real time; the ARM architecture core processor 10 controls the industrial computer to start or shut down according to the current time, the preset start time and the preset shutdown time.

[0048] Among them, industrial computers also include the Kylin operating system.

[0049] Furthermore, the embedded version of Kylin operating system is designed for scenarios such as the Internet of Things, industrial automation, and automotive electronics, and has the following features: streamlined system modules to reduce resource usage; fast startup and low-latency response; providing high-precision time management and task scheduling; supporting real-time task priority and hardware interrupt processing; low power consumption optimization; suitable for battery-powered devices and long-term operation scenarios; high compatibility with hardware; support for domestic hardware platforms (such as the D2000 processor); and providing targeted driver support and optimization.

[0050] In addition, the motherboard has built-in 16GB DDR4 memory, providing stronger performance support. Feiteng D2000 provides a variety of interfaces, including 1 SATA3.0 interface, 1 M.2 interface, VGA, HDMI, LVDS display interface, 6 USB2.0 interfaces and 4 USB3.0 interfaces, etc., to meet different connection needs. In the field of industrial control, it also provides 4 USB3.0, 8 USB2.0 interfaces, 1 Gigabit network card interface, etc., to ensure the diversity of equipment and high-speed data transmission.

[0051] ‌Among them, BIOS (Basic Input / Output System) can also perform hardware initialization and system booting. BIOS can be responsible for performing self-test (POST) when the industrial computer starts, checking and initializing hardware components such as memory, hard disk, graphics card, etc. It will also find and load the boot loader, handing control to the operating system to start the industrial computer. BIOS is usually stored in a flash memory chip on the motherboard and is a type of firmware. Firmware is software embedded in a hardware device and has a certain degree of immutability. Users can enter the BIOS setup interface by pressing specific keys (such as F2, DEL, or ESC) to configure hardware settings such as boot order, system clock, hard disk configuration, etc. ‌Traditional BIOS‌: Based on a 16-bit processor architecture, it supports a limited number of hardware and storage devices. ‌UEFI (Unified Extensible Firmware Interface): Modern computers often use UEFI as a replacement for BIOS, providing richer features such as support for larger hard drives, faster boot times, graphical user interfaces (GUIs), secure boot, etc. Modern BIOS / UEFI provides some security features, such as setting a boot password and preventing unauthorized operating system booting, to protect the computer from malware and unauthorized access. BIOS can add new features or fix known problems by updating the firmware. However, improper updates may cause the system to fail to boot, so caution is required. ‌BIOS can provide the computer with the lowest level and most direct hardware identification, detection and control in the industrial computer system to ensure that the hardware works properly and the operating system starts correctly. The BIOS program is stored in the ROM chip, which sets and manages the basic input and output system of the microcomputer to keep the system's hardware configuration running in the best state.

[0052] Among them, the RTC clock IC (Real-Time Clock) can provide accurate clock and calendar information, including year, month, day, week, hour, minute and second, etc. The RTC clock IC adopts low-power technology, which makes the power consumption extremely low in standby mode, which helps to extend the battery life and is particularly suitable for portable devices or systems that run for a long time. The RTC clock IC has an internal integrated alarm and timer function. Users can set specific time trigger events or perform timing tasks as needed. RTC clock IC usually supports multiple communication interfaces, such as I²C, SPI, etc. RTC clock IC is widely used in various devices that require precise time timing, such as portable devices, consumer electronics, embedded systems, industrial computers, etc.

[0053] As an example, referring to FIG. 2 , in an exemplary embodiment, another timed power on / off method based on an ARM architecture core processor is provided, including:

[0054] S201, determining whether the power-on time has been reached according to the power-on time pre-set in the BIOS and the current time.

[0055] S202, when the power-on time arrives, notify the ARM architecture core processor to power on.

[0056] Specifically, the industrial computer can be powered on through the following steps: after the ARM architecture core processor receives the power-on signal, it starts the power management chip or directly controls the power supply to power on the system; the ARM architecture core processor loads the BIOS, and starts the Kylin operating system after initialization is completed.

[0057] For example, in the step of scheduled startup, the ARM architecture can configure the RTC Alarm to trigger the system startup process through the wake-up pin; after receiving the RTC signal, the PMIC is controlled to turn on the main power supply.

[0058] As an example, referring to FIG. 3 , in an exemplary embodiment, another timed power on / off method based on an ARM architecture core processor is provided, including:

[0059] S301, determining whether the shutdown time has been reached according to the shutdown time pre-set in the BIOS and the current time.

[0060] S302, when the shutdown time is reached, notify the ARM architecture core processor to shut down.

[0061] Specifically, the ARM architecture core processor is shut down through the following steps: sending a shutdown command to the Kylin operating system; controlling the Kylin operating system to save target data and complete shutdown.

[0062] The step of obtaining the current time from the RTC clock IC in real time includes: the BIOS communicates with the RTC clock IC through an I²C or SPI interface, and obtains the current time at preset time intervals.

[0063] Specifically, the power-on time can be set by the following steps: responding to the user's operation of configuring the power-on time in the BIOS setting interface; storing the power-on time set by the user in a non-volatile memory.

[0064] Specifically, the shutdown time can be set by the following steps: in response to the user's operation of configuring the shutdown time in the BIOS setting interface, the shutdown time set by the user is stored in a non-volatile memory.

[0065] Exemplarily, the ARM architecture can cooperate with the BIOS to set the shutdown time in the scheduled shutdown step; and notify the operating system to save data and then turn off the power through GPIO or a dedicated signal line.

[0066] Exemplarily, the ARM architecture can also act as a bridge to work in conjunction with the BIOS, RTC, and operating system; and transmit shutdown or startup instructions through ACPI or other communication protocols.
