A Method for Realizing Concentrator's Remote Upgrade of Multi-thread Parallel

Abstract

The invention discloses a method for realizing remote upgrading in multi-thread parallel of a concentrator, and relates to a method for realizing multi-thread parallel. The method comprises the following steps: firstly, preparing encrypted tape files; carrying out packet sending on each tape file according to a data structural diagram; defaulting to build seven channel threads in a set C; computing a running situation of sub channels at any time by a main channel during an execution process; managing the channels and performing parallel computation; enabling each sub channel to run independently; dividing a whole big file into a plurality of small data blocks; resending packet replacing data; upgrading multiple devices at the same time; building a block data content format. According to the method for realizing the multi-thread parallel, disclosed by the invention, a remote multi-thread technology is used for equipment remote upgrading of the concentrator; the method is used for realizing automatic upgrading of a multi-thread concurrent device of the concentrator by utilizing an existing gprs (General Packet Radio Service) communication technology according to a storage structure and an upgrading principle of an embedded device.

Description

technical field [0001] The invention relates to a method for multi-thread parallel operation, in particular to a method for realizing remote upgrade of a concentrator with multi-thread parallel operation. Background technique [0002] With the increasing number of concentrators used by power companies, they have been widely used across the country, and various manufacturers will have the following problems when upgrading equipment: 1) In some remote mountainous areas, personnel cannot upgrade quickly and efficiently, and the efficiency is low. 2) Now There are some devices in areas with weak signal. The upgrade data files are repeatedly re-delivered due to upgrade interruption and communication failures. Breakpoint technology is not used. 3) Some manufacturers’ remote upgrade can only upgrade one device. The efficiency of data file distribution is low. 4) In the past, human management required on-site U disk upgrades or program upgrades with portable laptops. When the number...

Breakpoint technology is not used. 3) Some manufacturers’ remote upgrade can only upgrade one device. The efficiency of data file distribution is low. 4) In the past, human management required on-site U disk upgrades or program upgrades with portable laptops. When the number of devices is large and widely distributed, the upgrade process will be cumbersome High cost and long time, etc., the work efficiency is extremely low
