Abstract

A method for on - line upgrading network includes electric - connecting universal MCU to at least two external data storages and to network, starting up said MCU to confirm one of two said storages to be used as main service state and the other to be used as back up, executing service program in main state of storage and responding on - line upgrade request of network by said program, writing data packet from network in backup storage, varying state of two said storages, changing main service state storage to be backup one and changing backup storage with write - in data packet to be main service state storage.

Description

technical field [0001] The invention relates to network communication technology, in particular to a network online upgrading system. Background technique [0002] Most of the prior art adopts a relatively advanced CPU to realize the network online upgrade function, and the CPU itself has an Ethernet interface, such as an ARM9 processor. But there is no general-purpose MCU (microcontroller) at present to realize the online upgrade function of the network. Contents of the invention [0003] The purpose of the present invention is to provide a system that uses a low-cost, low-cost general-purpose MCU instead of an expensive, high-cost CPU to realize the online upgrade function of the network. The system can be used when the program is running without interrupting the business and without visiting On-site, upgrade and replace the currently running application. [0004] In order to achieve the above object, the online network upgrade method provided by the present invention ...
