Obviously, the drawings described below are some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0031] Figure 4 This is a schematic diagram of the structure of an electronic device provided in this application.

[0032] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] On the production line of battery-powered electronic devices, such as mobile phones and tablets, there's a chance that an electronic device might be accidentally turned on. If an electronic device is accidentally turned on and remains powered on for an extended period, it can lead to significant battery drain. This can cause the device to require charging before subsequent testing, slowing production efficiency.

[0035] Currently, there are several ways to prevent electronic devices from accidentally starting up:

[0036] First, by installing the battery as the last component in the assembly process of the electronic device, the electronic device can be prevented from accidentally starting up during the assembly process. However, this implementation method has high requirements for the structural design of the electronic device and has low universality.

[0037] Second, by adding a current detection module to the electronic device, the operating current of the electronic device is detected. After the electronic device is accidentally turned on, if the operating current of the electronic device is detected to be non-zero, it indicates that the electronic device is in the on state. The electronic device can then perform a shutdown operation to prevent the electronic device from accidentally turning on. However, this implementation requires adding an additional current detection module to the electronic device, which increases the cost of the electronic device and reduces the production efficiency of the electronic device.

[0038] Third, manual methods can be used to periodically test the operating current of electronic devices using a current detection device. If the operating current of the electronic device is detected to be non-zero, the electronic device is determined to have been accidentally powered on. However, manual testing of electronic devices may result in missed detections or incorrect judgments. Therefore, the above-mentioned manual methods for preventing electronic devices from accidentally powering on are less accurate and result in lower production efficiency of electronic devices.

[0039] Considering that existing methods for preventing electronic devices from being accidentally powered on have the above-mentioned problems in solving the problem of how to prevent electronic devices from being accidentally powered on, the present application provides a method for shutting down an electronic device when the identification of a component installed in the last process of assembling the electronic device is not read. This method solves the problem of how to prevent electronic devices from being accidentally powered on, and the program corresponding to this method can be integrated into the processor of the electronic device, without the need to add an additional detection circuit to the electronic device, which does not increase the cost of the electronic device. In addition, the method provided by this application can prevent electronic devices from being accidentally powered on without manual intervention, thereby improving the accuracy of preventing electronic devices from being accidentally powered on and the production efficiency of electronic devices.

[0040] Taking the above electronic device as a mobile phone or tablet computer as an example, Figure 1 This is a schematic diagram of an application scenario of the method for preventing accidental startup provided by this application. Figure 1As shown, the program of the method for preventing accidental startup provided by the present application can be stored in the central processing unit (CPU) of the electronic device. For example, the device installed in the last step of assembling the electronic device can be, for example, the display screen of the electronic device. The display screen includes a display screen driver chip that stores the identification of the display screen. Figure 1 As shown, the display driver chip and the CPU of the electronic device can transmit information through a circuit connection. For example, the display screen can be a liquid crystal display (LCD), a cathode ray tube (CRT), an organic light-emitting diode (OLED), or other types of display screens. In this example, the display screen is installed as the last step in assembling the electronic device. Therefore, there are no high requirements for the structural design of the electronic device, and it has higher universality than existing methods.

[0041] It should be understood that Figure 1 The application scenario of the present application is described only by taking the above-mentioned electronic device as a mobile phone or tablet computer and the device installed in the last process of assembling the electronic device as a display screen as an example. By way of example, the above-mentioned electronic device may also be, for example, a smart bracelet, an MP4 video player or other device. In specific implementation, for example, the device installed in the last process of assembling the electronic device may be determined based on the type of electronic device and / or the actual needs of the user. By way of example, the device installed in the last process of assembling the electronic device may also be, for example, a microphone, an indicator light, or a camera lens of the electronic device.

[0042] The following detailed description of the technical solution of the present application is provided in conjunction with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0043] Figure 2 This is a flow chart of a method for preventing accidental startup provided by this application. Figure 2 As shown, the method includes the following steps:

[0044] S101: Receive a power-on instruction for an electronic device.

[0045] For example, after the power button of the electronic device is pressed for a preset time period, the electronic device may receive a power-on instruction for the electronic device.

[0046] S102 : During a process of performing a power-on operation on the electronic device according to the power-on instruction, it is determined whether an identification of a target device of the electronic device can be read.

[0047] The target device is the device installed in the last step of assembling the electronic device. During the power-on process of the electronic device, if the electronic device fails to read the target device identifier from the target device, it indicates that the assembly process of the electronic device has not been completed. The electronic device can then execute step S103 to prevent the electronic device from being accidentally powered on. If the electronic device can read the target device identifier from the target device, it indicates that the assembly process of the electronic device has been completed. Optionally, the electronic device can execute step S104.

[0048] For example, during a power-on operation, the electronic device may interact with a target device to read information about the target device. The electronic device then determines whether the target device identification is obtained after reading the target device information to determine whether the target device identification is read from the target device of the electronic device. If the electronic device is able to obtain the target device identification after reading the target device information, it is determined that the target device identification is read from the target device of the electronic device. If the electronic device is unable to obtain the target device identification after interacting with the target device, it is determined that the target device identification is not read from the target device of the electronic device.

[0049] The identification of the target device mentioned above may be, for example, an identity document (ID) of the target device, a unique identification code, or other identification that can distinguish the target device.

[0050] S103: Shut down the electronic device.

[0051] Optionally, when it is determined that the electronic device fails to read the identification of the target device from the target device, the electronic device may stop executing the power-on operation and directly execute the power-off operation to prevent the electronic device from being accidentally powered on.

[0052] S104: Continue to power on the electronic device.

[0053] After determining that the electronic device can read the target device identifier from the target device, the electronic device can continue to perform the power-on operation. It should be understood that this application does not limit the specific operations performed during the power-on operation of the electronic device. For example, during the power-on operation, the electronic device can also initialize the device installed on the electronic device "before the electronic device receives the power-on instruction" to enable the device to operate normally.

[0054] It should be understood that this application does not limit the order of the various operating steps during the power-on operation of the electronic device. For example, the electronic device may first perform an initialization operation on a device (such as a camera lens, a button, etc.), and then perform an operation to read the identification of the target device. Alternatively, the electronic device may first perform an operation to read the identification of the target device, and then perform the initialization operation of the device. Alternatively, the above operations may be performed simultaneously.

[0055] In this embodiment, if the target device identifier cannot be read from the target device "installed in the final step of assembling the electronic device" during the power-on operation, the electronic device is shut down to prevent accidental power-on of the electronic device. Furthermore, this method does not require the addition of additional detection circuitry to the electronic device, thus increasing the cost of the electronic device. Furthermore, this method prevents accidental power-on of the electronic device without requiring human intervention, thereby improving the accuracy of the prevention and the production efficiency of the electronic device.

[0056] For example, the application scenarios of this application are described below with reference to specific scenario examples:

[0057] For example, taking the electronic device as an electronic device on a production line, after receiving a power-on command for the electronic device, if the electronic device can read the display screen identifier from the display screen, indicating that the display screen is installed, that is, the process of assembling the electronic device is complete, the electronic device can continue to perform the power-on operation. If the electronic device cannot read the display screen identifier, indicating that the display screen is not installed, the electronic device needs to perform a power-off operation to prevent the electronic device from accidentally starting up.

[0058] Alternatively, the electronic device may also be, for example, an electronic device used by a user. In this scenario, illustratively, the electronic device may also receive, for example, the user's permission configuration for the electronic device. Taking the installation of the display screen as an example, which is the last process of assembling the electronic device, the electronic device may determine whether to execute the step of reading the identification of the display screen during the startup of the electronic device based on the above-mentioned permission configuration. Exemplarily, if the electronic device receives a configuration instruction of "reading the identification of the display screen during the startup process", the electronic device may execute the step of reading the identification of the display screen in all subsequent startup processes. If the electronic device receives a configuration instruction of "not reading the identification of the display screen during the startup process", the electronic device may not execute the step of reading the identification of the display screen in all subsequent startup processes.

[0059] In the above scenario, if the electronic device receives a configuration instruction of "reading the display screen identification during the boot process", assuming that the display screen of the electronic device fails (for example, the display screen is broken, etc.) and the display screen needs to be replaced, during the display screen replacement process, if the electronic device receives a boot instruction for the electronic device, it can be determined whether the display screen identification can be read from the display screen of the electronic device during the boot operation. If it can be read, it means that the replacement display screen is successfully installed, and the boot operation can continue. If it cannot be read, the electronic device is shut down to prevent the electronic device from starting up by mistake, so as to avoid errors in the system operation of the electronic device due to the display screen not being initialized after replacement.

[0060] Furthermore, for components installed before powering on, electronic devices can typically initialize them during the power-on process to ensure normal operation. However, for components installed during or after powering on, the electronic device may not be able to initialize them during the power-on process, which can cause errors in the electronic device system and, in turn, cause the electronic device system to freeze. In other words, if an unassembled electronic device is accidentally turned on, it may also cause the electronic device system to freeze.

[0061] Taking into account the above possibilities, as a possible implementation method, when the identification of the target device cannot be read from the target device of the electronic device, the electronic device can also perform a restart operation and determine whether the number of restart operations reaches a preset number, and whether the identification of the target device cannot be read from the target device of the electronic device each restart.

[0062] If the number of restart operations reaches a preset number and the target device identification cannot be read from the target device of the electronic device each restart, it means that there may be a problem with the system operation of the electronic device and the problem may not be solved by restarting the electronic device. In this case, the electronic device can be shut down.

[0063] If the number of restart operations reaches a preset number, and the restart operation when the preset number is reached can read the identification of the target device from the target device of the electronic device, it means that after the preset number of restarts, the system of the electronic device can operate normally, and optionally, the power-on operation can continue to be performed on the electronic device.

[0064] If the number of restart operations does not reach the preset number, and the identification of the target device cannot be read from the target device of the electronic device during each restart, the electronic device is continued to be controlled to restart.

[0065] If the number of restart operations does not reach the preset number, the target device identification can be read from the target device of the electronic device during the restart process, indicating that the system of the electronic device can operate normally after the restart operation, and the power-on operation can continue to be performed on the electronic device.

[0066] Taking the above-mentioned preset number of times as 3 as an example, after failing to read the target device identification from the target device of the electronic device, the electronic device can still perform the first restart operation. Assuming that the target device identification cannot be read from the target device of the electronic device during this restart operation, that is, the number of restart operations does not reach the preset number, and the target device identification cannot be read from the target device of the electronic device during the restart, the electronic device performs the second restart operation.

[0067] Assuming that during the second restart operation, the identification of the target device can be read from the target device of the electronic device, the number of restart operations has not reached the preset number, and the identification of the target device can be read from the target device of the electronic device during the restart process, the power-on operation can continue to be performed on the electronic device.

[0068] If the target device identification cannot be read from the target device of the electronic device during the second restart operation, the electronic device performs a third restart operation. If the target device identification cannot be read from the target device of the electronic device during the third restart operation, the electronic device can be shut down.

[0069] Optionally, the electronic device may determine whether to perform a restart operation on the electronic device by, for example, judging whether an identification of a target device can be read from the target device of the electronic device within a preset time.

[0070] If the target device identification cannot be read from the target device of the electronic device within the preset time, it indicates that an error may have occurred in the system operation of the electronic device. The electronic device can then be restarted to initialize the devices assembled on the electronic device, thereby enabling the system of the electronic device to operate normally.

[0071] If the target device identification can be read from the target device of the electronic device within the preset time, it means that the system of the electronic device is operating normally and the process of assembling the electronic device has been completed, then the electronic device can continue to be powered on.

[0072] Exemplarily, the above-mentioned step of determining whether to perform a restart operation on the electronic device by judging whether the identification of the target device can be read from the target device of the electronic device within a preset time can be implemented, for example, by a watchdog mechanism. The watchdog mechanism refers to a counter that can be reset within a preset time. When the watchdog mechanism is started, the counter starts counting automatically. When an error occurs in the system operation of the electronic device, the electronic device will not be able to reset the count of this counter. If the counter is not reset, the electronic device performs a restart operation when the value of the counter is greater than the preset value. When the system of the electronic device is operating normally, the electronic device clears the counter at a preset time interval to prevent the value of the counter from being greater than the preset value, thereby preventing the electronic device from performing a restart operation.

[0073] It should be understood that this application does not limit how to determine the above-mentioned preset number of times and the preset time. For example, the above-mentioned preset number of times and the preset time can be determined based on the actual needs of the user and / or the type of electronic device, and pre-stored in the electronic device.

[0074] Alternatively, when the identification of the target device cannot be read from the target device of the electronic device, the electronic device may perform a restart operation on the electronic device according to a preset period, and determine whether the number of restart operations reaches a preset number, and whether the identification of the target device cannot be read from the target device of the electronic device during each restart.

[0075] Figure 3 This is a schematic diagram of the structure of a device for preventing accidental startup provided by this application. Figure 3 As shown, the device includes: a receiving module 21 and a processing module 22.

[0076] The receiving module 21 is configured to receive a power-on instruction for the electronic device.

[0077] The processing module 22 is used to perform a shutdown operation on the electronic device when the identification of the target device cannot be read from the target device of the electronic device during the process of performing a power-on operation on the electronic device according to the power-on instruction; wherein the target device is a device installed in the last process of assembling the electronic device.

[0078] Optionally, the processing module 22 is specifically used to perform a restart operation on the electronic device when the identification of the target device cannot be read from the target device of the electronic device; if the number of restart operations reaches a preset number and the identification of the target device cannot be read from the target device of the electronic device during each restart, then perform a shutdown operation on the electronic device.

[0079] Optionally, the processing module 22 is specifically configured to perform a restart operation on the electronic device when the identification of the target device cannot be read from the target device of the electronic device within a preset time.

[0080] Optionally, the processing module 22 is further configured to, when the number of restart operations does not reach the preset number, continue to perform the power-on operation on the electronic device when the identification of the target device is read from the target device of the electronic device.

[0081] Optionally, the processing module 22 is further configured to, during the process of powering on the electronic device according to the power-on instruction, continue to power on the electronic device when the identification of the target device can be read from the target device of the electronic device.
