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.
