The invention provides an OBD terminal upgrading method, system and device and a storage medium, and relates to the technical field of Internet of Vehicles. According to the method, whether the terminal needs to be upgraded or not is judged by obtaining the upgrade package information which comprises the memory occupied capacity and the version identifier. Through comparison with the current version of the terminal, whether upgrading is needed can be accurately judged. If upgrading is needed, whether the memory occupied capacity is smaller than the first storage space capacity of the terminal or not is judged to ensure that the space is sufficient. Obtaining an upgrade package of the corresponding version, wherein the upgrade package comprises an update component; before the updating component is written, the old system of the first storage space is backed up to the second storage space, and the old system of the first storage space is deleted. After the updating component is written into the first storage space, the terminal is upgraded through the component. If upgrading fails, the old system can be recovered to the first storage space from the second storage space, and rollback is achieved. Through the operation, the OBD terminal upgrading stability and reliability are improved.

    本申请提供了一种OBD终端升级方法、系统、设备及存储介质,涉及车联网技术领域。该方法,通过获取升级包信息,该信息包含内存占用容量和版本标识,以判断终端是否需要且能够进行升级。通过与终端当前版本对比,可准确判断是否需升级。然后若需升级,会判断内存占用容量是否小于终端第一存储空间容量,以确保空间充足。获取对应版本的升级包,其中包含更新组件。在写入更新组件前,会将第一存储空间的旧系统备份到第二存储空间,并删除第一存储空间的旧系统。更新组件被写入第一存储空间后,利用该组件升级终端。若升级失败,可以从第二存储空间将旧系统恢复到第一存储空间,实现回滚。通过上述操作,提高OBD终端升级稳定性和可靠性。
