The cloud-computing-based power communication monitoring system according to claim 1, wherein the switching statistical module is configured to count size of information generated by the power system and switching time after the fault node sends the encrypted information to the mobile phone terminal, and perform switching value calculation for the power consumer, and the specific calculation steps are as follows:
SS 1: setting the size of the encrypted electric power system generation information sent to the mobile phone terminal by the fault node as FZi(ii) a The switching time is recorded as TZi；
SS 2: using formulas
Acquiring and obtaining a switching value JW of a power consumerZi(ii) a Q1, q2 and q3 are all preset proportionality coefficients, and rho is a correction factor and is 0.8743291;
SS 3: the switching statistical module sends the calculated switching value of the power consumer to a cloud server for storage;
and the cloud server directly sends the switching value of the power consumer to the power payment system to carry out electric charge deduction according to a preset proportion.
