Problems solved by technology

[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 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

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings.

[0030] 1. Prepare the encrypted tape file first, and its byte is F byte. This block determines the size of each block of data stream D word according to the situation of the region (the size of each packet of byte selected for transmission if the signal is good or bad) Section, cut into N small file blocks by the number of bytes, and process each small file format, [header file 68H] + data length + data content + checksum of this small file + end of file, the destination device is receiving When this file is packaged, check the integrity and accuracy of the package, divide F by D, if it is divisible, it will be directly divided into N data blocks, if it cannot be an integer (N+1) blocks.

[0031] 2. Each block is grouped and sent according to the following data structure diagram.

[0032]

[0033] The content of the block data format is a...

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...
