s3, the power distribution substation directly managed by the power distribution master station is called a primary power distribution substation, the power distribution substation directly managed by the primary power distribution substation is called a secondary power distribution substation …, and the like, the power distribution substation directly managing the Internet of things equipment is called an n-level power distribution substation;
s4, the distribution main station transmits information in a 5G communication encryption mode when controlling the first-level distribution substation, the control electric signal obtained by encrypting the distribution information is recorded as A, and the encryption key is recorded as a first-level encryption key K1The first-level encryption key K is spliced by using character strings1After the encrypted control electric signal A is spliced, the obtained result is the information content transmitted from the power distribution main station to the first-stage power distribution substation, and is recorded as A1；
S5, the information content transmitted by the first-level distribution substation when controlling the second-level distribution substation is required to be A1On the basis of the first encryption, the transmitted information content is marked as A2The second encryption key is recorded as a second-level encryption key K2And the secondary encryption key K is spliced by using character strings2Is spliced to the pair A1After the result of the second encryption, the obtained splicing result is the information content transmitted from the first-stage distribution substation to the second-stage distribution substation, namely A2；
…
The information content transmitted by the S (n +3) and n-1 level distribution substation when controlling the n level distribution substation is required to be An-1On the basis of the data, the nth encryption is carried out, and the transmitted information content is marked as AnThe n-th encryption key is recorded as n-level encryption key KnThe n-level encryption key K is spliced by using character stringsnIs spliced to the pair An-1After the nth encryption result, the obtained splicing result is the information content transmitted from the n-1 level power distribution substation to the n level power distribution substation, namely An；

The obtained information content is verified by each level of distribution substation, so that the information content A can be obtainedbAnd the corresponding b-th encryption key can also detect the correctness of the acquired content, and for the wrong information content, the distribution substation needs to acquire again.
Further, in step S1, the internet of things data processing module determines the information collected by the internet of things data collection module as follows:
s1.1, acquiring data acquired by each piece of Internet of things equipment in an Internet of things data acquisition module;
s1.2, acquiring the model and number corresponding to the Internet of things equipment corresponding to each acquired data and the upper and lower limit values of the corresponding threshold;
