then the third evaluation value w =0.5 × t 2/(t 1+ t 2) +0.5 × ty/tc,
calculating the comprehensive evaluation value P =0.5 u +0.4 v +0.1 w of the transfer node,

5. The safety detection method for the power communication network based on the 5G as claimed in claim 4, wherein: the determining whether to transmit the communication data to be transmitted to the suspect node or the auxiliary node comprises:
respectively obtaining the communication data processing quantities N1 and N2 of the current doubt node and the auxiliary nodes thereof,
if N1-N2 is greater than the first throughput threshold, the communication data to be transmitted is transmitted to the secondary node,
if N1-N2 is less than the second throughput threshold, transmitting the communication data to be transmitted to the suspect node,
otherwise, setting the node which is positioned before the doubt node and transmits the communication data to be transmitted as a candidate node, the auxiliary node and the doubt node as reference nodes, respectively selecting a reference node from the candidate nodes for each reference node,
the selecting a reference node from the candidate nodes for each base node comprises:
selecting a node which has transmitted the same communication data as the reference node in the history transmission process from the candidate nodes as a first node of the reference node, and setting the same communication data as central data,
comparing the similarity of the priority ordering of the communication data transmitted by a reference node and all the first nodes when the corresponding central data is transmitted, and selecting the first node with the maximum priority ordering similarity as the reference node of the reference node;
and respectively acquiring the priority sequence of the auxiliary nodes and the reference nodes of the doubt nodes when the communication data to be transmitted is transmitted, selecting the reference nodes corresponding to the reference nodes with the higher priority sequence as transmission nodes, and transmitting the communication data to be transmitted to the transmission nodes.
6. The safety detection method for the power communication network based on the 5G as claimed in claim 4, wherein: the auxiliary node is a node except for the transit node in the transmission path.
7. The safety detection method for the power communication network based on the 5G as claimed in claim 4, wherein: the determining whether to transmit the communication data to be transmitted to the suspect node or the auxiliary node further comprises:
and when one of the in-doubt node and the auxiliary node is detected to be abnormal, transmitting the communication data to be transmitted to the other one of the in-doubt node and the auxiliary node.
