Embodiment 1
[0019] figure 1 The implementation flow of the remote program upgrade method provided by Embodiment 1 of the present invention is shown, and the details are as follows:
[0020] It should be noted that this method is applicable to the terminal upgrade in the wireless network mode of the server, and is especially suitable for the upgrade of the vehicle terminal. The vehicle-mounted terminal is the front-end equipment of the vehicle monitoring and management system, and is generally secretly installed in various vehicles. The vehicle-mounted terminal equipment is mainly composed of various external devices such as a vehicle-mounted video server, an LCD touch screen, an external camera, a call handle, and a car anti-theft device. .
[0021] In step S101, the server pushes the upgrade information of the application or the system to each vehicle-mounted terminal in real time.
[0022] In this embodiment, the upgrade information of the application or system refers to the version o...
Embodiment 2
[0034] figure 2 A specific structural block diagram of the server provided by Embodiment 2 of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown. In this embodiment, the server 1 includes: a version updating unit 11 , a version pushing unit 12 and an upgrading unit 13 .
[0035] Wherein, the version push unit 12 is used to push the upgrade information of the application or system to each vehicle-mounted terminal in real time;
[0036] The upgrade unit 13 is used to, if the version carried by the upgrade information is higher than the current version, use the upgrade package of the application or system through the air interface, and check the integrity of the upgrade package through MD5, and then update the vehicle The application or system of the terminal is upgraded, and the upgrade package includes an OTA package and a FOTA package.
[0037] Among them, the upgrade unit also has a dy...

Abstract
The invention belongs to the technical field of wireless communication and provides a remote program upgrading method and a server. The method comprises the steps that the server pushes the upgrading information of an application or a system to all vehicle-mounted terminals in real time; the vehicle-mounted terminals automatically obtain the upgrading information of the application or the system on the server; the vehicle-mounted terminals judge whether a version carried by the upgrading information of the application or the system is higher than a current version of the application or the system or not; if the version carried in the upgrading information is higher than the current version, the vehicle-mounted terminals obtain upgrading packages of the application or the system through air interfaces, the integrity of the upgrading packages is verified through the MD5, and then applications or systems of the vehicle-mounted terminals are upgraded, wherein the upgrading packages comprise an OTA package and an FOTA package. According to the remote program upgrading method and the server, the automatic upgrading of the systems or the applications of the vehicle-mounted terminals is achieved through the air interfaces, recall is not needed, and upgrading cost is low.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a remote program upgrading method and a server. Background technique [0002] At present, the form of terminal equipment of the Internet of Vehicles is characterized by diversification and complexity. Since the operating systems and development languages running on the terminal equipment are also very different, the code reuse rate is very low, the research and development efficiency is low, and the research and development cost remains high. , and most of the terminal devices are still closed operating systems, therefore, the existing terminal devices of the Internet of Vehicles cannot support the dynamic loading of application software and system control firmware upgrades (Firmware Over The Air, FOTA). Unlike ordinary mobile communication products, the installation and debugging of the terminal equipment of the Internet of Vehicles is very complic...
