Abstract

本申请公开了一种用于OTA批量升级的并发冲突管理系统及方法，涉及OTA升级技术领域，该方法包括：利用适配升级时间窗口对预设升级周期进行划分，确定适配升级时间窗口序列；基于适配升级时间窗口序列分别对若干台终端设备进行升级执行概率与网络连接状态预测，构建预测升级成功概率分布；以最小化整体升级时长与最小化整体升级失败概率为目标，进行优化搜索，输出最优升级批次分层方案；按照最优升级批次分层方案控制OTA云端平台依次向各批次中的终端设备下发升级指令，执行批量升级任务。解决了现有升级技术中由于终端设备数量众多、网络状况复杂多变以及系统资源有限等因素，导致升级失败、设备异常甚至系统崩溃的问题。
