The invention relates to the technical field of battery charging and swap, and in particular to an off-line battery swap method, a battery charging and swap station, a vehicle with a battery to be swapped, and a readable storage medium. The invention is intended to solve the problem that battery swap cannot be performed at a battery charging and swap station when a vehicle is not connected to a network or a cloud server has a fault. To this end, the off-line battery swap method of the invention includes: switching, by a battery charging and swap station, to a backup battery swap mode upon receiving a battery swap mode switching instruction; establishing, by a vehicle with a battery to be swapped, a communication connection with the battery charging and swap station by using backup connection information; authenticating, by the battery charging and swap station, the vehicle with a battery to be swapped; and performing, by the battery charging and swap station, battery swap for the vehicle with a battery to be swapped where the authentication is successful, the backup connection information being pre-stored in the vehicle with a battery to be swapped. According to the battery swap method of this application, a battery swap procedure can be completed in an off-line state, thereby effectively solving the problem that battery swap cannot be performed when a cloud server has a fault or a vehicle with a battery to be swapped is not connected to a network.

A system upgrade assessment method based on system parameter correlation coefficients is provided. The problem that the existing system upgrade assessment method cannot accurately assess an upgraded system is solved. For such a purpose, the system upgrade assessment method comprises the following steps: acquiring first data for a plurality of parameters before system upgrade (S); acquiring second data for the plurality of parameters after the system upgrade (S); calculating first correlation coefficients of the first data and second correlation coefficients of the second data (S); calculating third correlation coefficients between the first data and the corresponding second data (S); and determining, based on the magnitudes of the first correlation coefficients, the second correlation coefficients and the third correlation coefficients, whether the system upgrade succeeds (S). By comparing the correlation coefficients of the system parameters before and after the upgrade, the system upgrade assessment method can accurately determine whether the system upgrade succeeds.

A method and apparatus are provided for delivering multicast media in a network in which at least some nodes do not support delivery of multicast packets. A RTSP SETUP request is sent to a streaming server to send multicast packets, encapsulated within unicast wrappers, to a gateway node in the network. The RTSP SETUP request includes details both of the multicast destination address, and of the unicast destination address of the gateway node, requiring an extension to the RTSP protocol as currently defined and enabling the media server to send multicast packets in a unicast tunnel dynamically.
