  5. 根据权利要求4所述居民用户负荷辨识模块的升级方法，其特征在于：步骤2具体操作过程为，上级设备采用组播方式下发升级文件，待升级负荷辨识模块收到后按协商好的加密算法对升级包进行解密，并将解密后的数据包按照序号存储到对应位置，上级设备通过查询方式确认升级文件是否收全，对于未收全的待升级负荷辨识模块，采用点对点方式传输丢失的数据包，升级文件下载完成后，待升级负荷辨识模块对升级文件进行整体校验判断，以确定升级文件的完整性，校验通过后进入下一步。The method for upgrading the resident user load identification module according to claim 4, characterized in that: the specific operation process of step 2 is that the upper-level device uses the multicast method to issue the upgrade file, and the load identification module receives the upgrade according to the negotiated encryption The algorithm decrypts the upgrade package, and stores the decrypted data package in the corresponding location according to the sequence number. The upper-level equipment confirms whether the upgrade file is received in the query mode. For the uncollected load identification module to be upgraded, adopt the point-to-point method to transmit the lost After the download of the data package and the upgrade file is complete, the load identification module to be upgraded will perform an overall verification and judgment on the upgrade file to determine the integrity of the upgrade file. After the verification is passed, proceed to the next step.
  6. 根据权利要求1所述居民用户负荷辨识模块的升级方法，其特征在于：步骤3中所述升级 事件记录包括升级结果、升级前后版本、发生事件以及事件序号。The method for upgrading a resident user load identification module according to claim 1, wherein the upgrade event record in step 3 includes the upgrade result, the version before and after the upgrade, the occurrence event, and the sequence number of the event.
  7. 根据权利要求1所述居民用户负荷辨识模块的升级方法，其特征在于：在步骤1所述的准备阶段之前，还设有上级设备下发升级配置命令至待升级负荷辨识模块，待升级负荷辨识模块应答升级配置命令的步骤。The method for upgrading the load identification module of a resident user according to claim 1, characterized in that: before the preparation phase in step 1, an upper-level device is also provided to issue an upgrade configuration command to the load identification module to be upgraded, and the load identification to be upgraded The module responds to the steps of the upgrade configuration command.
