Self-upgrade method for equipment in remote online monitoring system

Abstract

The invention belongs to the field of wireless communication, and particularly relates to a self-upgrade method for equipment in a remote online monitoring system. The method is characterized in that: each piece of terminal equipment performs self-upgrade and self-maintenance through the remote online monitoring system consisting of a terminal table tool, a data acquisition unit and a background server based on a GPRS (General Packet Radio Service). The method mainly comprises the following steps that: the background server manages an application program and version information; the data acquisition unit periodically inquires a version log and downloads a new version program; the data acquisition unit realizes self-upgrade and upgrades the terminal table tool; and after the new version program is updated successfully, skipping is performed and an old version program is still kept for later use. In the method, the GPRS, storage space management, a file sub-package mechanism, a transmission response mechanism, a mode for continuous transmission at break-points and an IAP (Internet Access Provider) program programming mode are combined, and the accuracy and reliability of data transmission are ensured; and under the condition of not influencing normal use of a user, the equipment upgrading and maintaining problems of large quantity and wide distribution are solved quickly and efficiently.

Description

technical field [0001] The invention belongs to the field of electronic wireless communication, and in particular relates to a method for self-upgrading equipment in a remote on-line monitoring system. Background technique [0002] With the rapid development of electronic technology, computer technology and communication technology, embedded systems have been widely used in industry, military, communication, information appliances and other fields. To continuously improve, developers must be able to upgrade or maintain the system in a timely manner according to customer needs, so as to extend the system life cycle, improve system performance, and enhance system adaptability. The traditional embedded system upgrade method usually requires maintenance personnel to arrive at the device site, rewrite or replace the FLASH storage components out of the box.

Problems solved by technology

The traditional embedded system upgrade method usually requires maintenance personnel to arrive at the device site, rewrite or replace the FLASH storage components out of the box. When the number of devices is large and the distribution range is wide, the workload of this upgrade and maintenance method will be very large, and it will cost a lot of time. Long time, high cost, and even affect the normal use of users

In recent years, the method of Ethernet can better solve the problem of batch upgrade, but it is also difficult to achieve in remote areas in the wild or places where wired networks cannot reach the sea.
