the above-mentioned ways of updating the preset values of n, m and/or T in S3 are as follows,
1. a manual mode;
namely: manually changing preset values of n, m or/and T, wherein the value of m is manually changed into the actual meter reading success rate of the power utilization terminal of each distribution area; the change of the n and T values is determined to obtain an optimal value through repeated experiments;

In the embodiment, the step of reading the common data can be performed when one of three conditions is met in the reading process, so that the method is more efficient and is more suitable for reading the electricity consumption terminal in a complex operation environment. As shown in fig. 2, when the preset values of n, m, and/or T are manually updated, the value of m can be changed to the actual meter reading success rate, for example: for a certain distribution area with poor networking, the m is modified into 90, so that the step of reading common data by the power acquisition terminal can be accelerated, the step of reading common data by the power acquisition terminal is not required to be started when the reading success rate of important data is 98%, and in addition, the optimal value of each parameter is determined by the method for automatically updating n, m or/and P shown in the figure 3, so that the reading progress is further accelerated.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
