In an embodiment, as shown in fig. 3, step S300 may specifically include the following steps:
step S311, when the verification fails, forbidding establishing normal communication connection with the Internet of things communication node inside the target Internet of things terminal M3;
step S312, generating communication abnormity reminding information;
step S313, feeding back the communication exception information to the internet of things cloud platform M1.

In an embodiment, as shown in fig. 4, step S400 may specifically include the following steps:
step S410, receiving information collected by a target Internet of things terminal M3, classifying the information, and forming a class of data set by the same class;
step S420, calculating a difference value between a data value of a certain class in the data set and a reference value of the class, and determining the difference value as a first difference value; the absolute value of the first difference is greater than or equal to a preset threshold value, and the data set is marked as a giant variable data set; marking the data set as a safety data set when the absolute value of the first difference is smaller than a preset threshold value;
step S430, uploading the giant variable data set and the security data set to the internet of things cloud platform M1 according to different time intervals.
The internet of things cloud control gateway M2 classifies information, such as temperature information, humidity information, water pressure information and the like; classifying the same type of the data, and classifying the same information detected in different areas into a type of data sets, such as temperature information of different floors, outdoor temperature information and the like; and comparing the acquired information with a reference value, wherein the temperature reference value is 15 ℃, the deviation value is 30 ℃, and the detected temperature information is in normal information between-15 ℃ and 45 ℃, so that the temperature information condition in the south is met (the north is adjusted according to the actual condition). When the detected temperature information exceeds 45 ℃, such as a first floor fire and other conditions, the temperature information at the first floor exceeds the temperature information range of-15 ℃ to 45 ℃, is abnormal information, and is marked as a giant variable data set.
Taking the information uploaded for one time in 5 minutes between the traditional internet of things cloud control gateway M2 and the internet of things cloud platform M1 as an example, the information uploaded for one time in 5 minutes is both traditional without distinguishing a giant variable data set and a safety data set; the cloud control gateway M2 of the Internet of things uploads the giant variable data set once in 1 minute and uploads the safety data set once in 10 minutes; due to the fact that the uploading interval of the abnormal information is shorter, the internet of things cloud platform M1 updates the abnormal information faster and is higher in timeliness, and for the safety information, due to the safety of the safety information, the delayed uploading influence is smaller. Because the abnormal information appears less, and most of the abnormal information appears as the safety information under the conventional condition, the bandwidth occupation can be reduced, and the feedback is more timely when the abnormal information appears. The uploading time can be adjusted according to actual conditions.
In an embodiment, as shown in fig. 5, step S410 may specifically include the following steps:
step S411, acquiring acquisition information;

step S432, determining uploading time intervals of the giant variable data sets and the safety data sets according to the ratio range, and uploading the giant variable data sets and the safety data sets to an Internet of things cloud platform M1;
step S433, when the ratio between the giant variable data set and the safety data set is not within the preset ratio range, feeding back abnormal information to the Internet of things cloud platform M1.
For a specific example, for example, the ratio 1 between the giant variable data set and the safety data set is 19, in the interval of 0 to 0.1, the giant variable data set is uploaded once in 1 minute, and the safety data set is uploaded once in 10 minutes; the ratio of the giant-variable data set to the safety data set is 2, wherein the giant-variable data set is uploaded once in 2 minutes and the safety data set is uploaded once in 20 minutes within the interval of 0.1-0.2; by analogy, the ratio of the giant-variable data set to the safety data set is 6, the giant-variable data set is uploaded once in 5 minutes and the safety data set is uploaded once in 50 minutes in an interval of 0.4-0.5; the more the giant variable data sets are, the longer the feedback time of the giant variable data sets is, the interval of 0.4-0.5 is the maximum preset ratio range, when the ratio between the giant variable data sets and the safety data sets exceeds 0.5, the abnormal information is excessive, and the ratio information is fed back to the internet of things cloud platform M1. The ratio and the uploading time can be adjusted according to the actual condition.

and the difference transmission module 43 uploads the giant variable data set and the safety data set to the internet of things cloud platform M1 according to different time intervals.
The internet of things cloud control gateway M2 receives information collected by the internet of things terminal M3, classifies the information, judges whether the information is abnormal or not according to whether the absolute value of the difference value between the information and the reference value is too large or not, the abnormal information marks the data set of the abnormal information as a giant variable data set, the normal information marks the data set of the abnormal information as a safety data set, and the uploading frequency of the giant variable data set is higher than that of the safety data set because the information in the giant variable data set is abnormal and is worth paying attention and needs to be located in time, and the information in the safety data set is in the normal value, and the uploading interval time is small under the influence of prolonging, so that the abnormal information is updated by the internet of things cloud platform M1 in time.

For a specific example, for example, the ratio 1 between the giant variable data set and the safety data set is 1, in the interval of 0 to 0.1, the giant variable data set is uploaded once in 5 minutes, and the safety data set is uploaded once in 10 minutes; in the interval of 0.1-0.2, the giant variable data set is uploaded once in 4 minutes, and the safety data set is uploaded once in 20 minutes; by analogy, the ratio of the giant variable data set to the safety data set is between 0.4 and 0.5, the giant variable data set is uploaded once in 1 minute, and the safety data set is uploaded once in 50 minutes; the more the giant variable data sets are, the shorter the feedback time of the giant variable data sets is, the interval of 0.4-0.5 is the maximum preset ratio range, when the ratio between the giant variable data sets and the safety data sets exceeds 0.5, the abnormal information is excessive, and the ratio information is fed back to the internet of things cloud platform M1. The ratio and the uploading time can be adjusted according to the actual condition. The giant variable data set and the safety data set are uploaded according to different time intervals according to the ratio of the giant variable data set to the safety data set, so that the occupied bandwidth of the uploaded information is low, and the abnormal information can be timely processed.
