Abstract

The invention belongs to the technical field of train broadcasting systems, and particularly relates to a remote online firmware updating method and device based on a train broadcasting system. The method comprises the steps: reading BOOT parameters in an on-chip memory, receiving a firmware updating file sent by a remote updating server, storing the firmware updating file in an off-chip memory, checking the firmware updating file, setting the BOOT parameters for firmware updating after the firmware updating file passes through the verification, moving the verified firmware updating file from the off-chip memory to the on-chip memory, and updating the firmware of terminal equipment through the verified firmware updating file to obtain the updated firmware of the terminal equipment. According to the method, remote online firmware updating is realized by configuring the BOOT parameters and partitioning the memory of the terminal equipment.

Description

technical field [0001] The invention belongs to the technical field of train broadcasting systems, and in particular relates to a remote online firmware update method and device based on a train broadcasting system. Background technique [0002] In the field of train broadcasting system technology, it is often necessary to remotely update the computer system online. Generally speaking, when the computer system equipment has new functions or repairs software bugs, it needs to update the firmware of the system. The firmware update of the existing system is generally through There are two ways to update by disassembling the devices one by one or using the CAN-Bus bus to update. But generally speaking, a computer system is mostly composed of multiple devices, and its structure is more complicated. For example, the train broadcasting system, there are as many as 8 types of broadcasting system devices for trains (6 marshallings) and a total of more than 200 devices. It can be seen...
