Embodiment 1

[0038] In the technical solutions disclosed in one or more embodiments, such as figure 1 As shown, a remote upgrade system for smart components based on vehicle Ethernet, including a vehicle networking platform, a TBOX terminal installed on the vehicle, an OTA Manager module and a target component to be upgraded; the vehicle networking platform communicates wirelessly with the TBOX terminal, and the TBOX terminal, The OTA Manager module is sequentially connected with the target components to be upgraded, and the OTA Manager module is respectively connected to the target components to be upgraded through multiple CAN buses and multiple vehicle-mounted Ethernets.

[0039] In this embodiment, by setting the transmission of the vehicle-mounted Ethernet and the CAN bus, parallel operation can be realized, and multiple target components can be upgraded at the same time. At the same time, each target component of the transmission path is relatively independent, avoiding the problems o...

Embodiment 2

[0047] This embodiment also provides a remote upgrade method for intelligent components based on vehicle Ethernet, which is used to realize data transmission control and upgrade control between the OTA Manager module and the target component, such as figure 2 shown, including the following steps:

[0048] Step 1, the OTA Manager module obtains the upgrade file package, and performs legality and file size identification on the upgrade file package;

[0049] Step 2, the OTA Manager module selects different transmission networks according to the file size for the legal file package according to the identification result, and sends an upgrade request to the target file;

[0050] Step 3, the OTA Manager module queries to obtain a reply to the upgrade request, and if the reply agrees to the upgrade, then send the Md5 value and the random seed value corresponding to the file package, otherwise, end;

[0051] Step 4, the target component calculates the password according to the seed v...

Embodiment 3

[0076] This embodiment also provides a remote upgrade method for intelligent components based on vehicle Ethernet, which can be implemented in the OTA Manager module, such as image 3 shown, including the following steps:

[0077] Step 1. Obtain the upgrade file package, and identify the legality and file size of the upgrade file package;

[0078] Step 2. Select different transmission networks according to the file size for the legal file package according to the identification result, and send an upgrade request to the target file;

[0079] Step 3. Query to obtain the reply of the upgrade request, if the reply is to agree to the upgrade, then send the Md5 value and random seed value corresponding to the file package, otherwise, end;

[0080] Step 4. Obtain the password calculated by the target component based on the seed value, verify the received password, and send the upgrade file if the password is verified to be correct.

[0081] In this embodiment, by setting different...

Abstract

The invention provides an intelligent element remote upgrading method and system based on a vehicle-mounted Ethernet. The system comprises an Internet of Vehicles platform, a TBOX terminal arranged ona vehicle, an OTA Manager module and a to-be-upgraded target element. The Internet of Vehicles platform is in wireless communication with the TBOX terminal; the TBOX terminal, the OTA Manager moduleand a target element to be upgraded are connected in sequence, and the OTA Manager module is connected with the target element to be upgraded through a plurality of CAN buses and a plurality of vehicle-mounted Ethernet. By setting transmission of the vehicle-mounted Ethernet and the CAN bus, parallel operation can be achieved, simultaneous upgrading of multiple target elements is achieved, and meanwhile, each target element of the transmission path is relatively independent, so that the problem of upgrading failure caused by packet loss, blockage and the like is avoided. According to the method, the legality of the file is verified before the upgrade file is transmitted, and the integrity of the file is verified after the upgrade file is transmitted to the target file, so that the securityof an upgrade system is ensured.

Description

technical field [0001] The present disclosure relates to the technical field related to intelligent control of construction machinery, and in particular, relates to a remote upgrade method and system for intelligent components based on vehicle Ethernet. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the rapid development of science and technology, the technological content of construction machinery in intelligent control is getting higher and higher, and the market demand is also increasing. More and more market demand has led to the update and iteration of intelligent components on construction machinery. The faster it is, the more programs need to be upgraded, and the larger the upgrade package, it is of great significance to realize the remote upgrade of large amounts of data. [0004] There are many intelligent components inst...
