Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention is described in further detail.

[0030] The present invention proposes an IAP-based configurable full-network remote node firmware upgrade method, which is applied to firmware upgrades in industrial systems, and its firmware upgrade system is embedded in industrial systems, including host computers, CPU modules of several PLCs, and several remote nodes , where the host computer communicates with several PLC CPU modules. Generally, the host computer and PLC CPU modules are connected by Ethernet network communication. The connection between the host computer and PLC CPU modules is relatively fixed, and each application environment is applicable. The Ethernet network environment adopted is relatively fixed, and the standard network communication protocol is also used, which is convenient for maintenance and use. The CPU module of each PLC is connected to multiple remote nodes in a variety of ways, which...

Abstract

The invention relates to an IAP (Internet Access Provider) based configurable full-network remote node firmware upgrading method, and aims to solve the problem that in the heterogeneous network environment, upgrading of remote node firmware is restricted by the bus fixing manner and the environment. The upgrading method comprises the following steps: a CPU module of a PLC (Programmable Logic Controller) is adopted to configure a bus protocol between the CPU module of the PLC and a remote node by receiving a bus configuration instruction sent by an upper computer; the CPU module of the PLC is adopted to send a received file upgrade instruction sent by the upper computer to a BOOT area of the remote node through the pre-configured bus protocol; after receiving the instruction, the BOOT area is adopted to control the remote node to erase an application program area; the upper computer is adopted to transmit a pre-configured upgrade file in a bus protocol format to the remote node through the CPU module of the PLC, and an application program of a remote node application program area is upgraded through an IAP module.

Description

technical field [0001] The invention relates to a firmware upgrading method, in particular to an IAP-based configurable full-network remote node firmware upgrading method. Background technique [0002] Existing methods for utilizing IAP to carry out online remote upgrade mainly include: in some prior art, the firmware file with upgrade is uploaded to the specific folder of the designated FTP server, and the host computer executes the upgrade command and enters the FTP upgrade mode; The host of the device starts the FTP protocol stack, logs in to the FTP server to find the specified upgrade file; the host of the electronic device automatically downloads the file, stores the downloaded file in the memory designated by the vehicle electronic device, and downloads the upgrade file downloaded from the FTP server The file performs upgrade burning. There are also some program update devices in the prior art, which mainly include a computer upper computer and a computer lower compu...
