A kind of dual backup OTA method applied to air conditioner controller, including the following steps: receiving upgrade package by wireless signal, the running state of partition is identified, and idle partition is regarded as target partition;After full erase operation is carried out to target partition, the voltage in the kernel of controller is obtained as first voltage;Chip temperature is obtained as first temperature;The data block of upgrade package is written into target partition, at each data block writing time, whether the data block of upgrade package can be written is judged based on first voltage, if can be written, then the first write rate of data block is obtained based on first voltage and first temperature, and data block is written at first write rate. Upgrade success rate and reliability are improved, write speed is optimized to reduce upgrade time, the adaptive capacity of system to dynamic environment is enhanced, to ensure that wireless upgrade process is smooth, efficient and safe and stable.

This invention relates to the field of equipment upgrade technology, and in particular to an OTA method and system based on a master node for multiple types and multiple physical links. The method includes: the cloud sending all device models requiring OTA and their corresponding program files to the master node; the master node matching and filtering to determine the device models to be upgraded; the master node selecting a device model and broadcasting an OTA matching session; the master node waiting for a preset time, receiving matching responses from slave nodes, and summarizing them to form a list of upgradable devices; the master node performing multiple rounds of broadcast OTA upgrades for that device model; repeating the broadcast upgrade to complete the broadcast upgrades for all device models to be upgraded; for devices where the broadcast upgrade fails, the master node initiating a point-to-point unicast OTA upgrade; and the master node summarizing the upgrade results and reporting them uniformly to the cloud. This invention, based on master node OTA, can broadcast files sent from the cloud to each slave node to be upgraded, thereby supporting mixed OTA upgrades for multiple types and multiple physical links.

This invention discloses a method for optimizing vehicle OTA upgrade paths based on in-vehicle dynamic network bandwidth awareness, relating to the field of vehicle software over-the-air (OTA) upgrade technology. The method includes: acquiring the dynamic available bandwidth capacity of the vehicle's internal network in real time and determining the upgrade task set for this OTA upgrade; performing path planning on the upgrade task set with minimizing the total upgrade time as the optimization objective and the dynamic available bandwidth capacity as a parallel resource constraint, generating at least one parallel upgrade strategy; selecting the optimal strategy from the generated parallel upgrade strategies and executing the OTA upgrade operation according to that strategy. This invention can dynamically plan the optimal upgrade path based on the real-time status of the vehicle network, solving the inefficiency problem caused by the inability of traditional upgrade methods to adapt to bandwidth changes, and significantly shortening the total upgrade time.

This invention discloses a method, apparatus, computer device, and storage medium for writing upgrade package images, relating to the field of image writing technology. The method includes: parsing an upgrade package file to obtain an image file to be written and multiple target write objects for image entries; identifying the image content of the image file to be written to obtain a target image type; determining a write path based on the target image type and the target write objects for each image entry; performing image writing on the image file to be written according to the write path to obtain single-write storage area information and a single-write operation result; verifying the mountability of the single-write storage area information to obtain a mount verification result; and adjusting the image writing based on the single-write operation result and the mount verification result. In this way, the images in the upgrade package file are identified at the content level, and the correct write path is automatically matched, thereby avoiding post-upgrade mount failures caused by mismatches between the image type and the write target.

Embodiments of the present application provide an electronic device, an upgrading method, a board card and a storage medium. The electronic device comprises a main control board, a switching board and a plurality of service boards. The main control board is configured to receive an upgrading instruction and an upgrading file from a host computer. When the upgrading instruction indicates that at least two target service boards are to be upgraded, the switching board is configured to be in a multicast mode, and the upgrading file is sent to the switching board. The switching board is configured to send the upgrading file to the at least two target service boards in parallel. The target service boards are configured to perform upgrading processing on the upgrading file. The electronic device uses an SRIO interface to connect the service boards with the main control board and the service boards, so that high-speed communication of data between different boards can be achieved. Meanwhile, the design of the multicast mode can avoid the low efficiency of upgrading the boards one by one, and significantly shorten the upgrading time.
