Embodiment 1

[0046] In one or more embodiments, a method for reliably upgrading a visual monitoring system is disclosed, which improves the data transmission method from three aspects: communication message structure, upgrade interaction process, and upgrade package file.

[0047] 1. This embodiment redefines the structure of the communication message, specifically:

[0048] masthead length type serial number content check Trailer

[0049] Among them, the header and the trailer: each occupy 2 bytes, which is convenient for message parsing and splitting the message; if the header and trailer of 1 byte are defined, the same data will easily appear; if the header and trailer of more than 2 bytes are defined, then It will reduce the packet segmentation efficiency.

[0050] Length: 2 bytes, used to identify the length of the message, which is convenient for the message parser to divide the message.

[0051] Type: occupies 2 bytes and identifies the purpose of this me...

Embodiment 2

[0080] In one or more embodiments, a reliable upgrade system for a visual surveillance system is disclosed, including a device to be upgraded and a backend; wherein, the device to be upgraded includes: a processor and a computer-readable storage medium, and the processing The controller is configured to perform the following process:

[0081] Receive the upgrade request initiated by the background;

[0082] Respond to received requests according to the current state of the device;

[0083] When the upgrade conditions are met, the upgrade data message sent by the background is received, and each message contains at least the upgrade file ID, the total number of packages and the current package number information;

[0084] Judging whether the data packet is completely received, if it is complete, the data is sent successfully; otherwise, send a supplementary packet request to the background until the data is completely received; the supplementary packet request includes at leas...

Abstract

The invention discloses a method and a system for reliably upgrading a visual monitoring and photographing system. The method comprises the following steps: receiving an upgrading request initiated by a background; when the upgrading condition is met, receiving an upgrading data message sent by the background, each message at least comprising an upgrading file ID, the total package number and current package number information; judging whether the data packet is completely received or not, and if so, indicating that the data is successfully sent; otherwise, sending a packet supplementing request to the background until the data is completely received, wherein the packet supplement request at least comprises an upgrade file ID, the number of unreceived packets and packet number information; and according to the received data messages, combining the files into an upgrading file. The background can timely know an upgrading result according to feedback information of the device; even if the device is not provided with an operation interface, a worker can confirm whether the device is successfully upgraded or not through the background.

Description

technical field [0001] The invention belongs to the technical field of visual monitoring and shooting of power transmission lines, and in particular relates to a method and system for reliably upgrading a visual monitoring and shooting system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The visual monitoring system includes a visualization device and a background. When an upgrade is required, the background sends an upgrade package data to the device; if the visualization device is not upgraded successfully, the system may not operate normally. Therefore, the communication stability of the visualization device and the background is of great importance. It is very important that the system works properly. [0004] In the prior art, most of the visualization devices and the background communicate through connection or connectionless; ...
