[0002] In 4G IP Camera (IPC) applications, the device is usually installed in an outdoor environment for monitoring and data collection. However, the power supply in the outdoor environment is often not stable enough, especially when using solar power. Voltage fluctuations may cause the device to unexpectedly lose power during firmware upgrades. This power outage will cause the device to enter a hung state and cannot start normally, which will seriously affect the device's availability and user experience.

[0003] Traditional methods of repairing network cameras usually rely on manual intervention. For devices distributed in remote areas, the repair process is not only cumbersome, but also causes prolonged equipment downtime, which in turn affects the continuity of monitoring and the integrity of data. In addition, due to unstable power supply in outdoor environments, the existing dual backup firmware mechanism and automatic restart mechanism may encounter power outages during the firmware upgrade process, resulting in firmware damage or the device failing to start normally, and cannot effectively deal with sudden power problems. In addition, the existing technology is relatively simple in fault detection, usually relying on device self-test or scheduled startup, and lacks real-time monitoring and judgment of system status, and cannot promptly detect and handle serious problems such as device hangs; in addition, in existing recovery solutions, the firmware recovery process often takes a long time, especially when restarting or re-downloading firmware from the backup firmware, which may cause long service interruptions.

[0056] The troubleshooting methods for 4G cameras include:

[0057] S100: If the second CPU 210 detects that the output signal of the first CPU 110 is abnormal, the second CPU 210 changes the on-off state of the multiplexer 130, and the multiplexer 130 connects the first CPU 110 to the second storage area 220;

[0058] S200: The first CPU 110 reads the repair boot program in the second storage area 220 and obtains the repair firmware from the server 300;

[0059] S300: the second CPU 210 changes the on / off state of the multiplexer 130, and the multiplexer 130 connects the first CPU 110 to the first storage area 120;

[0060] S400: The first CPU 110 writes the repair firmware into the first storage area 120;

[0061] S500: The first CPU 110 reads the first storage area 120 and runs the repair firmware to complete the repair.

[0062] Specifically, in this embodiment, the 4G camera fault repair method proposed by the present invention is applied to Figure 2The 4G camera shown in the figure is composed of a network camera 100, a 4G module 200 and a remote server 300, wherein the network camera 100 includes a first CPU 110 (CPU1), a first storage area 120 (FLASH A) and a multiplexer 130 (MUX); the 4G module includes a second storage area 220 (FLASH B) and a second CPU 210 (CPU2), the second storage area 220 stores a repair boot program, and the server 300 stores a repair firmware; the first CPU 110 is electrically connected to the input end of the multiplexer 130 through an IO port, the first storage area 120 is electrically connected to the first output end of the multiplexer 130, the second storage area 220 is electrically connected to the second output end of the multiplexer 130, the second CPU 210 is electrically connected to the control end of the multiplexer 130 through the IO port, the first CPU 110 and the second CPU 210 are electrically connected using a USB data cable, and the second CPU 210 is connected to the server 300 by wireless communication via the wireless cellular chip 230 inside the 4G module 200 .

[0063] Reference Figure 3, is a specific process of the fault repair method of the 4G camera of this embodiment, wherein the left side is the operation process of the network camera 100, and the right side is the operation process of the 4G module 200. When the network camera 100 is powered on normally, the initial on-off state of the multiplexer 130 is to connect the first CPU 110 with the first storage area 120, that is, CPU1 connects the data line and the control line of FLASH A, and reads the firmware of the first storage area 120FLASH A to run, and at the same time outputs a PWM signal to the second CPU 210 (CPU2) in the 4G module. The second CPU 210 detects the PWM signal output by the first CPU 110 in real time. If the second CPU 210 detects that the PWM signal is abnormal, for example, the PWM pulse in the signal is lost for more than one minute, it is determined that the working state of the first CPU 110 is abnormal, that is, the network camera 100 is hung, and then the second CPU outputs a control signal to the multiplexer 130MUX in the network camera 100 to change the on-off state of the multiplexer 130, so that the first CPU 110 is connected to the second storage area 220, that is, CPU1 connects the data line and the control line of FLASH B, which is step S100; after the first CPU 110 and the second storage area 220 are connected, the first CPU 110 is powered on and reset again, and the first CPU 110 reads the firmware of the second storage area 220 FLASH B to run, and the second storage area 220 uses an internal program to determine whether the current main control chip is the chip of the network camera 100, that is, the first CPU 110. If the judgment is correct, the first CPU 110 that currently controls the second storage area 220 is allowed to start calling and running the repair boot program stored in the second storage area 220. The repair boot program can guide the first CPU 110 to output a control signal to the second CPU 210, control the second CPU 210 to download and obtain the repair firmware from the remote server 300 through the wireless cellular 230, and transmit the repair firmware to the first CPU 110. After the first CPU 110 obtains the complete repair firmware from the second CPU 210, it stores it in the first CPU 110, the above is step S200; then the second CPU 210 controls the multiplexer 130 again, changes its on-off state, and makes the first CPU restore the connection with the first storage area 120, the above is step S300; then the first CPU 110 transfers the repair firmware in its own internal RAM to the first storage area 120, that is, step S400; finally, the first CPU 110 is powered on again, and runs normally to read the repair firmware and other working programs in the first storage area 120, thereby completing the repair of the device, that is, step S500, the device runs normally until the failure occurs again, and all the above steps are executed again.

[0064] By saving the repair firmware in the second storage area of ​​the 4G module of the 4G camera, and automatically switching the storage area read by the first CPU to read the repair firmware saved in the second storage area when the 4G camera device is hung, powered off or malfunctions, the entire process does not require manual intervention, thereby realizing the automatic self-repair function of the device, significantly reducing the complexity and time cost of equipment maintenance. By connecting the input port of the multiplexer to the first CPU, and the two output ports to the first storage area and the second storage area respectively, a hardware switching mechanism of the storage area is realized based on the multiplexer, so that when the device encounters voltage instability, it can still self-repair through the repair firmware in the second storage area of ​​the 4G module, thereby reducing the risk of firmware damage caused by power failure and enhancing the ability to cope with power failure. The output signal state of the first CPU of the network camera is detected by the second CPU of the 4G module, so as to determine whether the device is in a hung state, so that the self-repair program can be started accurately and quickly, the fault can be solved in time, the normal operation of the device can be ensured, and the fault detection and response capabilities of the device are improved. This method also optimizes the overall firmware recovery process to make the firmware update and recovery process more efficient, which can minimize the firmware recovery time and reduce device downtime, thereby ensuring user experience.

[0065] Reference Figure 1 and Figure 3 Further, in some embodiments of the present invention, step S200: the first CPU 110 reads the repair program in the second storage area 220 and obtains the repair firmware from the server 300, including:

[0066] (2.1) The network camera 100 is powered on again;

[0067] (2.2) The second storage area 220 determines the model of the current control chip;

[0068] (2.3) If the second storage area 220 identifies that the current control chip is the first CPU 110, the first CPU 110 is allowed to run the repair boot program in the second storage area 220;

[0069] (2.4) According to the repair boot program, the first CPU 110 obtains the repair firmware from the server 300 .

[0070] Specifically, in this embodiment, after the first CPU 110 is connected to the second storage area 220, the first CPU 110 is powered on again and reset, and the first CPU 110 reads the firmware of the second storage area 220 FLASH B to run. The second storage area 220 uses an internal program to determine whether the current main control chip is the chip of the network camera 100, that is, the first CPU 110. If the judgment is correct, the first CPU 110 that currently controls the second storage area 220 is allowed to start calling and running the repair boot program stored in the second storage area 220. The repair boot program can guide the first CPU 110 to output a control signal to the second CPU 210, control the second CPU 210 to download and obtain the repair firmware from the remote server 300 through the wireless cell 230, and transmit the repair firmware to the first CPU 110. After the first CPU 110 obtains the complete repair firmware from the second CPU 210, it stores it in the RAM inside the first CPU 110. By first determining whether the main control chip of the current second storage area 220 is the chip of the network camera 100, and then determining whether the chip is allowed to run the repair boot program, it is prevented that when the second CPU 210 of the 4G module 200 reads the second storage area normally, the repair boot program in the second storage area 220 is erroneously run, causing program errors and other problems. That is, the second storage area 220 includes both the 4G module program used when the second CPU 210 operates normally, and the repair boot program that needs to be called and run when an abnormality occurs in the device. When the device operates normally, the repair boot program cannot be erroneously called by the second CPU 210, and the repair boot program can only be called and run by the first CPU 110 when an abnormality occurs in the device.

[0071] Reference Figure 1 and Figure 2 , further, in some embodiments of the present invention, the 4G module 200 further includes a wireless cellular chip 230, the second CPU 210 is electrically connected to the wireless cellular chip 230, and the wireless cellular chip 230 is communicatively connected to the server 300; the first CPU 110 is electrically connected to the second CPU 210 via a USB port;

[0072] Step (2.4) According to the repair boot program, the first CPU 110 obtains the repair firmware from the server 300, including:

[0073] (2.4.1) The first CPU 110 controls the second CPU 210 through the USB port according to the repair boot program, so that the second CPU 210 controls the wireless cellular chip 230 to download the repair firmware from the server 300;

[0074] (2.4.2) The first CPU 110 controls the second CPU 210 to obtain the repair firmware from the wireless cellular chip 230 according to the repair boot program;

[0075] (2.4.3) The first CPU 110 controls the first CPU 110 to obtain the repair firmware from the second CPU 210 according to the repair boot program.

[0076] Further, in some embodiments of the present invention, step (2.4.2) the first CPU 110 controls the second CPU 210 to obtain the repair firmware from the wireless cellular chip 230 according to the repair boot program, including:

[0077] The first CPU 110 controls the second CPU 210 to obtain the repair firmware from the wireless cellular chip 230 according to the repair boot program, and downloads the repair firmware to the RAM of the second CPU 210 .

[0078] Further, in some embodiments of the present invention, step (2.4.3) the first CPU 110 controls the first CPU 110 to obtain the repair firmware from the second CPU 210 according to the repair boot program, including:

[0079] The first CPU 110 controls the first CPU 110 and the second CPU 210 to perform serial port communication according to the repair boot program;

[0080] The first CPU 110 downloads the repair firmware in the RAM of the second CPU 210 to the RAM of the first CPU 110 through serial port communication.

[0081] Further, in some embodiments of the present invention, step S100: if the second CPU 210 detects that the output signal of the first CPU 110 is abnormal, the second CPU 210 changes the on-off state of the multiplexer 130, and the multiplexer 130 connects the first CPU 110 to the second storage area 220, including:

[0082] The second CPU 210 continuously detects the output signal of the first CPU 110 . If the second CPU 210 detects that the output signal of the first CPU 110 is lost, the second CPU 210 changes the on / off state of the multiplexer 130 , and the multiplexer 130 connects the first CPU 110 to the second storage area 220 .

[0083] Specifically, in this embodiment, the second CPU 210 can continuously detect the PWM signal or other signal output by the first CPU 110. If the pulse of the PWM signal is lost for more than one minute, it is determined that the working state of the first CPU 110 is abnormal, and the second CPU 210 changes the on-off state of the multiplexer 130. The multiplexer 130 connects the first CPU 110 to the second storage area 220. When the 4G camera device is hung, powered off or malfunctions, the storage area read by the first CPU is automatically switched to read the repair firmware stored in the second storage area. The entire process does not require human intervention, thereby realizing the automatic self-repair function of the device and significantly reducing the complexity and time cost of equipment maintenance.

[0084] Further, in some embodiments of the present invention, step S500: the first CPU 110 reads the first storage area 120 and runs the repair firmware to complete the repair, including:

[0085] (5.1) The network camera 100 is powered on again;

[0086] (5.2) The first CPU 110 reads and runs the repair firmware in the first storage area 120 to complete the repair.
