Low-power image management system

Abstract

A low-power image management system includes: a main server communicatively connected to a plurality of image capturing devices, the plurality of image capturing devices including a first image capturing device; a first single-board computer communicatively connected to the main server; a second single-board computer communicatively connected to the main server; and a third single-board computer communicatively connected to the main server; wherein the main server determines one of the first single-board computer, the second single-board computer, and the third single-board computer as a main processing device, and determines the other two of the first single-board computer, the second single-board computer, and the third single-board computer as a first backup processing device and a second backup processing device, respectively; wherein the main server receives a first image processing instruction from the first image capturing device, the first image processing instruction indicating a first image data of the first image capturing device; wherein the main server, based on the first image processing instruction, causes the main processing device to receive and process the first image data of the first image capturing device.

Claims

1. A low-power image management system, comprising: a main server communicatively connected to a plurality of image capturing devices, the plurality of image capturing devices including a first image capturing device; a first single-board computer communicatively connected to the main server; a second single-board computer communicatively connected to the main server; and a third single-board computer communicatively connected to the main server; wherein the main server determines one of the first single-board computer, the second single-board computer, and the third single-board computer as a main processing device, and determines the other two of the first single-board computer, the second single-board computer, and the third single-board computer as a first backup processing device and a second backup processing device, respectively; wherein the main server receives a first image processing instruction from the first image capturing device, the first image processing instruction indicating a first image data of the first image capturing device; wherein the main server, based on the first image processing instruction, causes the main processing device to receive and process the first image data of the first image capturing device; In a first time period, the main server determines the first single-board computer as the main processing device, the second single-board computer as the first backup processing device, and the third single-board computer as the second backup processing device. In a second time period, the main server determines the second single-board computer as the main processing device, the third single-board computer as the first backup processing device, and the first single-board computer as the second backup processing device. The second time period follows the first time period. The first time period and the second time period have the same duration.

2. The low-power image management system of claim 1, wherein the plurality of image capturing devices includes a first group of image capturing devices, the first group of image capturing devices including the first image capturing device; wherein the main server receives a second image processing instruction from each of the first group of image capturing devices, the plurality of second image processing instructions respectively indicating a second image data, the plurality of second image data being respectively associated with one of the first group of image capturing devices; wherein the main server causes the main processing device to receive and process the plurality of second image data based on the plurality of second image processing instructions.

3. The low-power image management system of claim 2, wherein the plurality of image capturing devices includes a second image capturing device; wherein the main server receives a third image processing instruction from the second image capturing device, the third image processing instruction indicating a third image data of the second image capturing device; wherein the main server causes a first standby processing device to receive and process the third image data of the second image capturing device based on the total number of the first group of image capturing devices being equal to a first threshold.

4. The low-power image management system of claim 3, wherein the plurality of image capturing devices includes a second group of image capturing devices, the second group of image capturing devices including the second image capturing device; wherein the main server receives a fourth image processing instruction from each of the second group of image capturing devices, the plurality of fourth image processing instructions respectively indicating a fourth image data, the plurality of fourth image data being associated with one of the second group of image capturing devices; wherein the main server causes the first backup processing device to receive and process the plurality of fourth image data based on the plurality of fourth image processing instructions.

5. The low-power image management system of claim 4, wherein the plurality of image capturing devices includes a third image capturing device; wherein the main server receives a fifth image processing instruction from the third image capturing device, the fifth image processing instruction indicating a fifth image data of the third image capturing device; wherein the main server causes a second standby processing device to receive and process the fifth image data of the third image capturing device based on the total number of the second group of image capturing devices being equal to a second threshold.

6. The low-power image management system of claim 1, wherein the plurality of image capturing devices includes a fourth image capturing device; wherein the main server receives a sixth image processing instruction from the fourth image capturing device, the sixth image processing instruction indicating a sixth image data of the fourth image capturing device; wherein the main server causes a first backup processing device to receive and process the sixth image data of the fourth image capturing device when the main processing device is unable to receive the sixth image data of the fourth image capturing device.

7. The low-power image management system of claim 1, wherein the main server determines, during a third time period, the third single-board computer as the main processing device, the first single-board computer as the first backup processing device, and the second single-board computer as the second backup processing device; wherein the third time period follows the second time period.

8. The low-power image management system of claim 7, wherein the main server determines, during a fourth time period, the first single-board computer as the main processing device, the second single-board computer as the first backup processing device, and the third single-board computer as the second backup processing device; wherein the fourth time period follows the third time period.
