Problems solved by technology

[0002] Unmanned system is a general term for unmanned equipment such as drones, unmanned vehicles, and unmanned ships, as well as their supporting communication stations, take-off (launch) recovery devices, and transportation, storage, and detection devices for unmanned equipment. When M3, M4, M7 and other MCUs are used in the system as the controller, if you want to upgrade the system, you must open the structural parts of the unmanned system to upgrade, which is time-consuming and laborious, and the debugging efficiency is relatively low. If the system is sold to the client , may also need to travel to the client for upgrades
In addition, the existing upgrade technology uses a dual-partition mode, one part is the bootloader, and the other is the functional area, and the upgrade function is placed in the bootloader, so the protocol and function of the upgrade cannot be changed

Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0018] Such as figure 1 As shown, the present invention provides a high-reliability upgrade method for unmanned systems, which uses the storage space of the MCU, adopts the three-partition mode, and divides the system into three parts. The upgrade is performed under different partitions to ensure that the Partition security.

[0019] The method includes the following steps:

[0020] Step S1, at first, the Flash memory space of unmanned system controller MCU is di...

Abstract

The invention discloses a high-reliability upgrading method of an unmanned system. By adopting the storage space inside an MCU, the three-partition mode is adopted, the system is divided into three portions including one BootLoader partition and two function partitions, upgrading is performed in different partitions, new partitioning data is written in, the partition safety is ensured, MD5 checking is performed after data is written into the novel partition, the partition data writing integrity is ensured, upgrading of the unmanned system is safer and reliable, and absolute upgrading safety is achieved truly, system failure under various abnormal conditions is avoided, and the functions of changing an upgrading protocol and achieving upgrading can be achieved.

Description

technical field [0001] The invention belongs to the technical field of system upgrades, and relates to a system upgrade method, in particular to a high-reliability upgrade method for an unmanned system. Background technique [0002] Unmanned system is a general term for unmanned equipment such as drones, unmanned vehicles, and unmanned ships, as well as their supporting communication stations, take-off (launch) recovery devices, and transportation, storage, and detection devices for unmanned equipment. When M3, M4, M7 and other MCUs are used in the system as the controller, if you want to upgrade the system, you must open the structural parts of the unmanned system to upgrade, which is time-consuming and laborious, and the debugging efficiency is relatively low. If the system is sold to the client , and may also need to travel to the client for upgrades. In addition, the existing upgrade technology uses a dual-partition mode, one part is the bootloader, and the other part i...
