The subsystem modules at least include: Real-time video preview module, TF card video recording and playback module, cloud storage video module, remote device control module, platform interaction module and AI algorithm module; The registration interface includes: subsystem module name, subsystem module maximum inactivation time, and subsystem module exception handling function.

6. The method for monitoring firmware program based on embedded Linux system according to claim 1, characterized in that: The monitoring module based on the message queue checks whether there are any faulty modules in the subsystem modules in the network surveillance camera system, including: The monitoring module based on the message queue performs thread structured data inspection on the subsystem modules in the network monitoring camera system one by one; The subsystem module in the network surveillance camera system sends thread structured data communication information to the network surveillance camera system software care main thread module within a preset time interval; Check whether the subsystem module has exceeded the set maximum inactivation time and has not sent the thread structured data communication information to the network surveillance camera system software care main thread module; If the check result is that the subsystem module has exceeded the set maximum inactivation time and has not sent thread structured data communication information to the network surveillance camera system software care main thread module, it is determined that there is a faulty module.

7. The method for monitoring embedded Linux system firmware program according to claim 6, characterized in that: The subsystem modules in the network monitoring camera system send thread structured data communication information on demand to the network monitoring camera system software to take care of multiple optional Linux system communication methods used in the main thread module.

8. A device for monitoring firmware programs based on an embedded Linux system, characterized in that: include: Creation module: used to create the network surveillance camera system software care main thread module, and add a firmware program care processing module; Startup module: used to start the network surveillance camera system, perform initialization of the development kit, and start the new firmware program care processing module; Registration module: used for the subsystem module in the network monitoring camera system to register with the network monitoring camera system software care main thread module through the registration interface of the firmware program care processing module; Check module: a monitoring module based on a message queue is used to check whether there is a faulty module in the subsystem modules in the network monitoring camera system; Execution module: If the inspection result shows that there is a faulty module in the subsystem module of the network surveillance camera system, the fault information interface and fault processing interface in the firmware program care processing module obtain and record the fault information of the faulty module, execute the abnormal fault processing task, and complete the fault recovery.

9. An electronic device, characterized in that: include: Processor and memory; The processor is used to execute the method for monitoring embedded Linux system firmware program according to any one of claims 1 to 7 by calling the program or instruction stored in the memory.

10. A computer-readable storage medium, characterized in that: The computer-readable storage medium stores a program or instruction, and the program or instruction enables a computer to execute the method for monitoring embedded Linux system firmware program according to any one of claims 1 to 7.
