Abstract:
An OTA differential upgrade method and system for a master-slave architecture, which relate to the field of the Internet of Things. The method comprises: step S1, acquiring an upgrade scheme, and determining a master-slave connection relationship and an upgrade mode according to the upgrade scheme; step S2, downloading a differential upgrade file; and step S3, determining a processing mode of a master node according to the upgrade mode of a slave node, wherein if the upgrade mode of the slave node is a first-type mode, the master node performs flashing recovery on the differential upgrade file and then issues same to the slave node, such that the slave node completes an upgrade, and if the upgrade mode of the slave node is a second-type mode, the master node directly issues the differential upgrade file to the slave node, and performs the upgrade. By means of the method, the differential upgrade is realized by using a master node and a slave node, the advantages of a master-slave architecture are fully exerted, the flashing rate is increased, the upgrade period is shortened, and the upgrade stability is ensured.
