With the development of science and technology, the research, development, test and application of internet of things equipment are developed in a explosive mode, and more internet of things equipment are connected to an internet of things ecosystem with all things interconnected. In the face of a huge ecosystem of the internet of things, a 5G technology with low delay, high speed and high capacity is a better choice. The 5G technology can not only process a large amount of data loads of the Internet of things, but also integrate various intelligent systems and continuously achieve communication interaction. However, in the actual application process, the problem of data mistransmission occurs when the internet of things device runs.
When the existing internet of things system is used, data flow requirements of different internet of things applications are not distinguished, namely when different internet of things applications are used, the internet of things system meets all data flow requirements of the internet of things applications, and the problem that unreasonable services are provided for different applications with different requirements on bandwidth, time delay and loss rate can be caused in the large-flow multi-message type internet of things system; therefore, when the total internet of things is connected with more internet of things devices, the total bandwidth requirement of the total internet of things is very high, and the sum of the bandwidth occupation values of all the internet of things devices is reached, so that bandwidth resources are wasted very much.
Therefore, in order to solve the above problems, it is necessary to design a reasonable bandwidth allocation-based information communication method for the internet of things.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme:
an Internet of things information communication method based on bandwidth allocation comprises the following steps:
s1: acquiring the maximum occupied bandwidth M and the maximum occupied time T of the single-path bandwidth during the single-path work in the communication circuit of the Internet of things;
s2: acquiring an occupied bandwidth N of a highest-authority single channel in the communication circuit of the Internet of things during working;
s3: selecting a communication circuit with a preset bandwidth-time curve to control all single paths in the communication circuit of the Internet of things, so that the curve is distributed in a sine mode, the middle value of the curve is M, the peak top value is M + N, and the curve period is 2T;
s4: when the circuit of the Internet of things works, a single path with the authority value larger than a preset threshold value is determined as a high-authority single path, and other single paths are determined as low-authority single paths;
s5: the sum of the bandwidths of all the low-authority single paths is not higher than the bandwidth value of the bandwidth-time curve at the corresponding moment.
Preferably, when step S1 is executed, one internet of things main network in the internet of things circuit is connected to a plurality of internet of things devices, and the connection between each internet of things device and the internet of things main network is a single path.
Preferably, when step S1 is executed, each single channel is tested in turn to obtain the bandwidth and the occupied time of the single channel with the maximum bandwidth during operation.
Preferably, before step S2 is executed, each single path in the internet of things circuit is subjected to authority level division.
Preferably, when step S3 is executed, the maximum processing bandwidth of the total network of the internet of things in the communication circuit is not less than M + N.
As a preferable aspect of the present invention, the predetermined threshold value is set in advance before the step S4 is executed.
Preferably, in step S5, the communication circuit processes the high-priority unicast information with priority, i.e., the bandwidth is allocated to the high-priority unicast with priority.
The Internet of things information communication method based on bandwidth allocation has the beneficial effects that: the internet of things total network bandwidth can be set in a minimized mode under the condition that normal communication of the internet of things circuit is guaranteed, the waste of bandwidth resources is reduced, and the communication efficiency among the internet of things devices is effectively guaranteed.

Detailed Description
The following are specific examples of the present invention and further describe the technical solutions of the present invention, but the present invention is not limited to these examples.
Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the modules and structures set forth in these embodiments does not limit the scope of the invention unless specifically stated otherwise.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
Example (b): as shown in fig. 1, which is only one embodiment of the present invention, a bandwidth allocation based information communication method for internet of things includes the following steps:
s1: acquiring the maximum occupied bandwidth M and the maximum occupied time T of the single-path bandwidth during the single-path work in the communication circuit of the Internet of things;
here, when step S1 is executed, a total internet of things network in the internet of things circuit is connected to a plurality of internet of things devices, and the connection between each internet of things device and the total internet of things network is a single path.
When step S1 is executed, each single channel is tested in turn to obtain the bandwidth and the occupied time of the single channel with the maximum bandwidth during operation.
S2: acquiring an occupied bandwidth N of a highest-authority single channel in the communication circuit of the Internet of things during working;
before step S2 is executed, permission level division is performed on each single path in the internet of things circuit.
Note that N is typically less than M, but if the maximum bandwidth single is just the highest authority single, then N equals M.
S3: selecting a communication circuit with a preset bandwidth-time curve to control all single paths in the communication circuit of the Internet of things, so that the curve is distributed in a sine mode, the middle value of the curve is M, the peak top value is M + N, and the curve period is 2T;
when step S3 is executed, the maximum processing bandwidth of the total internet of things in the communication circuit is not less than M + N. In fact, the total processing bandwidth of the internet of things main network in the communication circuit can be M + N, and if the maximum bandwidth single path is just the highest authority single path, the maximum total bandwidth is 2M.
S4: when the circuit of the Internet of things works, a single path with the authority value larger than a preset threshold value is determined as a high-authority single path, and other single paths are determined as low-authority single paths;
before step S4 is executed, a predetermined threshold value is set in advance.
S5: the sum of the bandwidths of all the low-authority single paths is not higher than the bandwidth value of the bandwidth-time curve at the corresponding moment.
When step S5 is executed, the communication circuit preferentially processes the high-priority single channel information, i.e., the bandwidth is preferentially allocated to the high-priority single channel.
The bandwidth allocation-based Internet of things information communication method can set the total network bandwidth of the Internet of things in a minimized manner under the condition that normal communication of the Internet of things circuit is guaranteed, reduce the waste of bandwidth resources and effectively guarantee the communication efficiency among the Internet of things devices.
The present invention is not limited to the above-described specific embodiments, and various modifications and variations are possible. Any modifications, equivalents, improvements and the like made to the above embodiments in accordance with the technical spirit of the present invention should be included in the scope of the present invention.
