Problems solved by technology

This solution using a set of custom protocols not only has a complicated implementation process and low upgrade efficiency, but also is not conducive to the remote software upgrade of multiple terminals supported by the device terminal management center at the same time. It has disadvantages such as difficult system implementation and low success rate of software upgrade.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing.

[0015] Figure 1 illustrates the system architecture involved in the entire FTP wireless remote upgrade method. The equipment terminal management center and the FTP server are connected through the network, and the equipment terminal management center and the FTP server are connected to the embedded terminal remotely through the public IP network by means of GPRS wireless IP. The equipment terminal management center interacts with the embedded terminal for upgrade information to realize remote upgrade control and status display; the FTP server interacts with the embedded terminal for file data to realize wireless IP download of the upgrade file. The method adopts the FTP protocol and supports concurrent remote upgrade of multiple embedded terminals.

[0016] Fig. 2 illustrates the specific interaction flow of the equipment terminal management center, the embedded terminal a...

Abstract

The invention discloses a wireless remote updating method based on the embedded system software of FTP protocol, which comprises the following parts: management center of equipment terminal, FTP file server and embedded terminal, wherein the communication among the embedded terminal, management center of equipment terminal and FTP server is based on GPRS or CDMA1 wireless IP pattern, which supports multi-embedded terminals to update FTP remotely. The invention solves the defect of present updating pattern without defining complex wireless updating interactive protocol, which is an automatic remote updating method for software equipment.

Description

technical field [0001] The invention relates to the field of public network wireless communication, IP communication and embedded system, and relates to a method for wireless remote software upgrade of embedded system based on FTP protocol. Background technique [0002] At present, many equipment monitoring systems adopt a unified monitoring and management mode, which is manifested in the wireless remote monitoring and control of the operating status and mode of each equipment terminal by the equipment terminal management center. Usually, the terminal system needs to update its own software according to the needs of the application, which makes it very difficult to upgrade the software of the device terminal in various unmanned situations. The system with software wireless remote upgrade function can remotely upgrade the equipment without the need for maintenance personnel to go to the site, which can greatly reduce the maintenance cost of the system...
