Embodiment Construction
[0034] Below in conjunction with accompanying drawing, the present invention is described in further detail.
[0035] The present invention proposes an IAP-based configurable full-network remote node firmware upgrade system, 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...

The invention relates to an allocable full-network remote node firmware upgrading system and device based on an IAP. The allocable full-network remote node firmware upgrading system and device aim at solving the problem that in a heterogeneous network environment, upgrading of remote node firmware is limited by a fixed bus mode and the environment. The allocable full-network remote node firmware upgrading system comprises a bus allocation unit, a bus command transmitting unit, an upgrading preparation unit and an upgrading file transmission unit, wherein a bus protocol between a CPU module of a PLC and a remote node is allocated through the CPU module of the PLC by receiving a bus allocation command transmitted by an upper computer; the CPU module of the PLC transmits a received file upgrading command transmitted by the upper computer to a BOOT area of the remote node through the bus protocol allocated in advance, and the BOOT area controls the remote node to wipe an application program area after receiving the command; the upper computer transmits a pre-allocated upgrading file in the bus protocol format to the remote node through the CPU module of the PLC, and application programs in the application program area of the remote node are upgraded through an IAP unit.
Description
technical field [0001] The invention relates to a firmware upgrading system and device, in particular to an IAP-based configurable full-network remote node firmware upgrading system and device. Background technique [0002] Existing technology that utilizes IAP to carry out online remote upgrade mainly adopts the following schemes: in some existing technologies, 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 electronic 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 executes the file download, and stores the downloaded file in the memory designated by the vehicle electronic device, and then downloads it from the FTP server upgrade file to perform upgrade burning. There are also some program update devices in the prior art, which ...
