Method and system for upper computer to perform grogram upgrading on lower computer

Abstract

The present invention discloses a method and system for an upper computer to perform program upgrading on a lower computer to overcome defects of low online upgrading efficiency and high cost in the prior art. The method comprises: packaging, by the upper computer, an upgrading program into multiple data frames and transmitting the data frames to a transfer lower computer through a first communication network; receiving, by the transfer lower computer, the multiple data frames in order and acquiring lower computer identification information in each data frame; when determining that the data frames belong to an upgrading program of the transfer lower computer according to the lower computer identification information, upgrading a local application program by using all the data frames of the upgrading program; when determining that the data frames belong to an upgrading program of a non-transfer lower computer according to the lower computer identification information, transmitting the data frames to the non-transfer lower computer; and upgrading, by the non-transition lower computer, the local application program by using all the data frames of the upgrading program. The method and the system of the present invention improve the program upgrading efficiency of the lower computer, and significantly reduce the workload of program upgrading operation.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for a host computer to upgrade a program of a lower computer. Background technique [0002] In order to keep the software, data and other information of the control system in the latest state, it is necessary to update the software in real time or in a timely manner. However, when upgrading the software of multiple modules of the control system, if one module is upgraded gradually, there are obviously defects such as slow upgrade speed and heavy workload, which will not only affect the timeliness of software update, but also reduce The speed at which the instrument operates. [0003] The currently used instrument control systems commonly include embedded systems. Most of the online upgrade methods are based on a communication network. The upper computer sends upgrade commands to all lower computers one by one and upgrades. The upgrade steps are cumbers...

AI Technical Summary

Problems solved by technology

[0009] 1) The program upgrade based on a communication network needs to upgrade each main control board (lower computer) one by one. The upgrade steps are complicated and slow, and it is difficult to meet the needs of real-time updates;

[0010] 2) The communication network is single, which cannot meet the application environment and development trend of the increasingly diversified communication methods;

[0011] 3) For the program upgrade of a single network biochemical immune instrument, it is currently necessary to disassemble the shell of the biochemical immune instrument and install the shell after the upgrade is completed, which is time-consuming, labor-intensive, time-consuming, and inefficient
