specific Embodiment approach 1

[0028] Specific implementation mode 1. Combination figure 1 and figure 2 Illustrate this specific embodiment, the embedded remote universal upgrade system based on GPRS, it comprises server 1 and remote upgrade controller 2;

[0029] Remote upgrade controller 2 comprises CPU module 21, GPRS communication module 22, power circuit 23 and serial port circuit 24, and the GPRS signal input or output end of described CPU module 21 is connected with the GPRS signal output or input end of GPRS communication module 22; Described GPRS communication module 22 carries out wireless communication by GPRS network and server 1; The power signal output end of power supply circuit 23 is connected with the power signal input end of CPU module 21; connect.

[0030] Working principle: the server of the present invention is located at a fixed geographic location and IP address, and is used to store program files required for remote upgrade and control the entire upgrade process. The server can b...

specific Embodiment approach 2

[0032] Specific embodiment two, the difference between this specific embodiment and the embedded remote universal upgrade system based on GPRS described in specific embodiment one is that the remote upgrade controller 2 also includes a liquid crystal display operating circuit 25; the liquid crystal display operating circuit 25 The liquid crystal display operation signal output or input end of the CPU module 21 is connected with the liquid crystal display operation signal input or output end.

[0033] In this embodiment, the liquid crystal display operation circuit is used as the man-machine operation interface, and the remote staff can complete the corresponding upgrade configuration of the remote device and related operations during the upgrade process through this module.

specific Embodiment approach 3

[0034] Embodiment 3. The difference between this embodiment and the GPRS-based embedded remote universal upgrade system described in Embodiment 1 or 2 is that the main control chip of the remote device to be upgraded is ARM.

Abstract

The invention relates to an embedded remote universal upgrading system based on general packet radio service (GPRS) and a upgrading method based on the embedded remote universal upgrading system, which aims at solving the problems of the existing manual upgrading way that the labor and the material resource are greatly wasted and the universality of the upgrading system is poor. When a remote device needs to be upgraded, relevant upgrading configuration of the remote device is conducted by the remote working personnel through a liquid crystal screen of a remote upgrading controller, then an upgrading request and own internet protocol (IP) address are transmitted to a server, the server transmits a corresponding upgrading program file through a special upgrading software on the server to begin the upgrading. After the upgrading is completed, the remote device returns and transmits an upgrading completion log to through the remote upgrading controller so as to notify the server that the remote upgrading is completed. The embedded remote universal upgrading system and the upgrading method are suitable for upgrading the remote device to be upgraded.

Description

technical field [0001] The invention relates to an embedded remote universal upgrading system and an upgrading method based on the system. Background technique [0002] With the improvement of the requirements for system intelligence, more and more embedded systems are widely used in various automation control systems, and each automation system often contains multiple embedded systems at the same time. The software function upgrade of these embedded systems is inevitable. However, in existing systems, these embedded system upgrades generally have the following problems: [0003] 1. The traditional upgrade method requires a lot of time and manpower, and the cost is too high and the efficiency is low. [0004] At present, the traditional upgrade method adopted at home and abroad is to send technical staff to the site, and use a dedicated emulator to complete the software upgrade of the equipment at the site where the equipment is used. This is not only a waste of time and m...
