In the above methods, it is necessary to send the new firmware package to the camera through the network to replace the existing firmware package of the camera. However, once the network or power is cut off during the firmware upgrade process, the camera cannot be completed. Firmware upgrade, or even cause the camera to malfunction, the camera cannot operate normally, and the reliability of the firmware upgrade is low
For example, after storing part of the data of the new firmware package to the camera through the network (that is, replacing the existing firmware package of the camera), if there is a network or power failure at this time, the remaining data of the new firmware package cannot continue to be stored to the camera so that after the camera restarts, the camera will not function properly as the camera does not store the complete new firmware package

The invention provides a firmware upgrading method, device and equipment, and the method comprises the steps of obtaining a basic system firmware package from external equipment after it is determined that firmware upgrading needs to be carried out on a camera; storing the basic system firmware package in an application system storage area; after the basic system firmware package is successfully stored in the application system storage area, reading the basic system firmware package from the application system storage area, and storing the basic system firmware package in the basic system storage area; after the basic system firmware package is successfully stored in the basic system storage area, obtaining the application system firmware package from the external device, storing the application system firmware package in the application system storage area, and replacing the basic system firmware package in the application system storage area with the application system firmware package. According to the technical scheme of the invention, the camera can run the basic system firmware package and carry out firmware upgrading no matter at which moment the network disconnection or power failure occurs, so that the camera can run normally, and the power-off protection of firmware upgrading is realized.
Description
technical field [0001] The present application relates to the technical field of monitoring, and in particular to a firmware upgrading method, device and equipment. Background technique [0002] Firmware (Firmware) is a software program stored in EEPROM (Electrically Erasable Programmable ReadOnly Memory, Electrically Erasable Programmable Read-Only Memory) or FLASH (flash memory) chip, which can be used as the most basic and bottom-level software program of the operating system, which can realize driver functions. For example, BIOS (Basic Input Output System, Basic Input Output System) is a kind of firmware. [0003] Firmware upgrade refers to upgrading the firmware of the device to improve device functions, enhance device stability, and patch device vulnerabilities. The camera is an outdoor embedded device, and the actual application also involves the firmware upgrade of the camera. In order to realize the firmware upgrade of the camera, for the camera with a wired netw...
