Embodiment Construction

[0043] Such as Figure 5-8 As shown, what the present invention proposes is a method for upgrading the network camera system, which redesigns the system partition on the basis of the mainstream solution in the industry. The new partition diagram is shown in Figure 5 . The new solution modifies the root file system partition format from ubifs to ramdisk format, which greatly reduces the size of the root file system partition from 60M to 6M. The size of the application partition App partition is 42M and the size of the configuration file partition config partition is 8M. The entire system requires 60M of resources.

Abstract

The invention provides a network camera system online update method. Five subareas are employed. The subareas comprise a Boot subarea, a kernel subarea, a Ramdisk Rootfs subarea, a Ubifs App subarea and a Ubifs Config subarea. Moreover, a whole update process is divided into three parts. A first part comprises signal interaction. A second part comprises mirror downloading and application replacement. The second part can be divided into kernel update, file system update and application update. A third part comprises device reboot and update edition confirmation. According to the method, the waste of hardware storage resources resulting from a network camera update mechanism is reduced; the hardware cost is reduced; the problem that a system cannot be booted due to accidental power failure in an online update process of a network camera device can be solved. The interaction in the network camera update process is increased. The update progress is accurately tracked.

Description

technical field [0001] The invention belongs to the technical field of network cameras, and in particular relates to an online upgrading method of a network camera system. Background technique [0002] With the rapid development of the network, the development of digital security monitoring is advancing by leaps and bounds. More and more network cameras have begun to replace traditional analog cameras and become the mainstream of security monitoring. Network cameras can be installed anywhere in the world, remote preview through monitoring software, widely used to introduce the diversity of requirements, and remote maintenance and upgrading of cameras is also very important. [0003] At present, the common practice in the industry is to adopt the dual backup mechanism of the system. The system partition is shown as follows: figure 1 . The system uses four partitions, namely the boot partition Boot, the kernel partition kernel, and the main file system partition A adopts the...
