[0002] With the development of the Internet, the application scenarios of unattended devices are constantly expanding, and have penetrated into key fields such as industrial control, Internet of Things terminals, public services, and remote area deployment devices. The core demand of such devices is to achieve "stable operation without human intervention". The "automatic startup function when the AC power supply is interrupted and the power supply is restored" is the core technical support to ensure the continuity of unattended devices.

[0003] Currently, to achieve the automatic startup requirement in the above-mentioned unattended scenario, the mainstream technical solution in the industry relies on special circuit design at the hardware level. Specifically, the existing technical solution needs to integrate additional power state detection circuit, reset trigger circuit and other modules in the device, to ensure that the power-on logic can be triggered accurately when the power is restored, by maintaining the effectiveness of the hardware detection circuit or the configuration parameters during power failure.

[0004] However, this technical solution relying on hardware modification is cumbersome, not only increasing the complexity of device integration, but also difficult to meet the actual needs of fast integration and flexible adaptation of unattended devices. Therefore, how to realize the fast integration and flexible adaptation of the automatic startup function of unattended devices while avoiding complex hardware modification has become a technical problem to be solved in the field. SUMMARY

[0005] The embodiments of the present application provide a system startup method, a startup system, a device and a medium, aiming to solve the technical problem of how to realize the fast integration and flexible adaptation of the automatic startup function of unattended devices.

[0019] The detection unit is used to detect whether the value stored in the non-volatile memory is a first preset value when the target system is connected to a power source.

[0020] The startup unit is used to start the target system according to a preset startup sequence if the value stored in the non-volatile memory is the first preset value.

[0021] Optionally, the system also includes a target chip.

[0022] The detection unit is further configured to detect whether the value stored in the target register of the target chip is a second preset value when the target system is connected to power; if the value stored in the target register is the second preset value, detect whether the value stored in the non-volatile memory is the first preset value.

[0025] This application provides a system power-on method, power-on system, device, and medium. The method is applied to a target system, which includes a non-volatile memory. The method includes: when the target system is powered on, detecting whether the value stored in the non-volatile memory is a first preset value; if the value stored in the non-volatile memory is the first preset value, starting the target system according to a preset power-on sequence.

[0040] To address the technical challenge of rapidly integrating and flexibly adapting the automatic power-on function of unattended equipment in existing technologies, this application provides a system power-on method apparatus that enables rapid integration and flexible adaptation of the automatic power-on function of unattended equipment.

[0041] Figure 1a This is a flowchart illustrating a system power-on method provided in an embodiment of this application. In one embodiment, the method is applied to a target system, the target system including non-volatile memory, and the method includes: S101-S102.

[0042] S101. When the target system is powered on, check whether the value stored in the non-volatile memory is the first preset value.

[0043] Preferably, the target system is an embedded system based on an ARM platform. The non-volatile memory is an EEPROM. Since the data stored in the non-volatile memory remains unchanged after the power is turned off, this embodiment stores a first preset value in the non-volatile memory to indicate whether the target system needs to be started according to a preset power-on sequence.

[0044] Please see Figure 1b , Figure 1b This is a schematic block diagram illustrating a target system power-on setting provided in an embodiment of this application. In this embodiment, the first preset value can be 0x00. That is, when the value stored in the EEPROM is 0x00, it indicates that the automatic power-on switch of the target system is on. When the value stored in the EEPROM is 0x01, it indicates that the automatic power-on switch of the target system is off. Of course, the first preset value can also be other values. For example, the first preset value is 0x01. This application does not impose any limitations on this.

[0045] S102. If the value stored in the non-volatile memory is the first preset value, start the target system according to the preset power-on sequence.

[0046] The preset power-on sequence is the power-on sequence set by the applicant according to actual needs.

[0047] It should be noted that the hardware automatically powers on when the target system is plugged into an AC power source. The target system first runs the U-boot system, then reads the value from the EEPROM. If the value stored in the EEPROM is the first preset value, the target system boots according to the preset boot sequence, thus achieving automatic booting of the target system after AC power-on. Here, AC power refers to alternating current power.

[0048] This application provides a system power-on method. The method is applied to a target system, which includes a non-volatile memory. The method includes: when the target system is powered on, detecting whether the value stored in the non-volatile memory is a first preset value; if the value stored in the non-volatile memory is the first preset value, starting the target system according to a preset power-on sequence. Therefore, in this application's technical solution, when the target system is powered on, it detects whether the value stored in the non-volatile memory is the first preset value. If so, the target system is started according to the preset power-on sequence. Thus, the first preset value stored in the non-volatile memory is retained even after the target system is powered off. Furthermore, the first preset value is used to indicate whether the target system has an automatic power-on function. This mechanism requires no hardware modification; when the target system is powered on again, it only needs to detect whether the value stored in the non-volatile memory is the first preset value to achieve rapid integration and flexible adaptation of the target system's automatic power-on function.

[0049] In one embodiment, the target system further includes a target chip, and before S101 above, the method further includes: S103-S104.

[0050] S103. Detect whether the value stored in the target register of the target chip is the second preset value.

[0051] Preferably, the target chip is a target network interface card (NIC) chip. Of course, the target chip can also be other types of chips. This application does not impose any limitations on this. The target register of the target chip can be a register of the target NIC chip. For example, the target register can be the REG16 register of the NIC chip. This application does not impose any limitations on this.

[0052] S104. If the value stored in the target register is the second preset value, execute the step of detecting whether the value stored in the non-volatile memory is the first preset value.

[0053] It should be noted that S103-S104 will be explained in detail below.

[0054] This embodiment of the application aims to prevent the target system from automatically shutting down when the EEPROM value read after power is connected is not a first preset value. When the power button is pressed again, the target system continues to automatically shut down because the value stored in the EEPROM is not the first preset value. This embodiment adds a target chip that stores a second preset value in its target register. The above-described step S101 is only executed when the value stored in the target chip's target register is the second preset value. Therefore, this embodiment can control the value stored in the target chip's target register to prevent the target system from automatically shutting down when the power button is pressed again.

[0055] In one embodiment, the method further includes:

[0056] S105. If the value stored in the target register is not equal to the second preset value, write the third preset value into the target register.

[0057] It should be noted that the second preset value is not equal to the third preset value. In this embodiment, the third preset value is written into the target register to prevent the target system from automatically shutting down when the power button is pressed again. The third preset value was set by the applicant based on practical experience, and this application does not impose any limitations on it.

[0058] In one embodiment, after S101, the method further includes:

[0059] S106. Write the third preset value to the target register.

[0060] In this embodiment of the application, a third preset value is written into the target register so that the target system will not automatically shut down when the power button is pressed again.

[0061] In one embodiment, please refer to Figure 2 , Figure 2This is a second flowchart illustrating a system power-on method provided in this application embodiment. When the AC power is unplugged and then plugged back in, the network card register is reset to 0x00. At this time, the target system hardware automatically powers on. The CPU first reads the value of REG16 on page 0XD8A of the network card register. If the value read by the CPU is 0x0, it continues to read the value of the EEPROM. If the EEPROM value read by the CPU is not 0x0, the CPU writes 0x100 to REG16 on page 0XD8A of the network card register and then shuts down. If the EEPROM value read by the CPU is 0x0, the CPU writes 0x100 to REG16 on page 0XD8A of the network card register and then powers on. When the user manually presses the power button on the device containing the target system, since the network card chip is powered by S5, the value of REG16 on page 0XD8A of the network card register remains 0x100. At this time, the value read by the CPU on page 0XD8A of the network card register is not 0x0. Next, the CPU writes 0x100 to REG16 on page 0xD8A of the network card register and then powers on. In summary, this method allows the target system to boot according to a preset boot sequence when the AC power is unplugged and then plugged back in. Similarly, the target system can also boot according to the preset boot sequence when the user presses the power button.

[0062] See Figure 3 , Figure 3 This is a schematic block diagram of a power-on system provided in an embodiment of this application. Corresponding to the above system power-on method, this application also provides a power-on system.

[0065] In one embodiment, the system further includes a target chip 304.

[0066] The detection unit 302 is further configured to detect whether the value stored in the target register of the target chip is a second preset value when the target system is connected to power; if the value stored in the target register is the second preset value, detect whether the value stored in the non-volatile memory is the first preset value.

[0067] In one embodiment, the system further includes:

[0068] The writing unit 305 is used to write a third preset value into the target register if the value stored in the target register is not equal to the second preset value.
