It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Specific implementations of the invention are described in detail below in connection with specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a method for sending data of internet of things, the method includes the following steps:
S100, receiving a data transmission command, and generating predicted transmission completion time, wherein the data transmission command comprises data to be transmitted;

In the embodiment of the invention, no matter the internet of things equipment periodically uploads data by itself or the user uses the intelligent terminal to send data, a data sending command is generated. When the data transmission command is received, the predicted transmission completion time is automatically generated, the predicted transmission completion time is then judged, and when the predicted transmission completion time is smaller than or equal to a set transmission value, the set transmission value is a fixed value set in advance, so that the transmission speed of the wireless network can meet the transmission requirement at the moment, and the data is directly transmitted; when the predicted transmission completion time is greater than the set transmission value, it is indicated that the transmission speed of the wireless network cannot meet the transmission demand at that time, and it is necessary to transmit urgent data with priority. Specifically, whether the data transmission command contains the incidental information is detected, and when the incidental information is contained, the incidental information is directly extracted; when the auxiliary information is not included, the data transmission command is sent by a user instead of the internet of things equipment, emergency degree information to be selected is sent to the user terminal sending the data transmission command, the user needs to select the emergency degree, and finally, the embodiment of the invention can prioritize all the data to be transmitted according to the auxiliary information and the emergency degree and transmit all the data to be transmitted according to the ranking order, so that the relatively emergency data can be preferentially transmitted, and normal operation of the work is not affected as much as possible.

s101, receiving a data transmission command, and detecting the current wireless network transmission speed and the data quantity of all data to be transmitted;
s102, generating predicted transmission completion time according to the wireless network transmission speed and the data quantity of all data to be transmitted.
In step S102, the step of generating the predicted transmission completion time according to the wireless network transmission speed and the data amount of all the data to be transmitted includes the following sub-steps:
Step S1021, acquiring the transmission speed of the wireless network and the data volume of all data to be transmitted;

For network speed decay factorFor simulating the speed decay that may occur during network transmission, the larger the value is, which indicates that the network speed drops faster during long-time transmission, thereby increasing the transmission time.
In the embodiment of the invention, each time a data transmission command is received, the current wireless network transmission speed and the data quantity of all data to be transmitted are automatically detected, so that the predicted transmission completion time is obtained, and all data which need to be transmitted but do not need to be transmitted belong to the data to be transmitted.
As shown in fig. 3, as a preferred embodiment of the present invention, the step of prioritizing all data to be transmitted according to the incidental information and the emergency degree selection command specifically includes:
s401, equipment information and project information in the incidental information are called, and the equipment information and the project information are input into an equipment sending level library;
S402, outputting a transmission level corresponding to data to be transmitted, wherein the transmission level library comprises all equipment information, each piece of equipment information corresponds to a plurality of item information, and each piece of item information corresponds to a transmission level;
In step S402, the calculation formula of the transmission level corresponding to the data to be transmitted is expressed as:
，
Wherein, Indicating the transmission level to which the data to be transmitted corresponds,The weight of the device is represented by the weight of the device,Representing the overall weight of the device and,Representing the project impact factor(s),Indicating the proportion of the amount of data that has been transmitted,The total data amount of the item is represented,The weighted values representing other influencing factors besides the device and project factors,Representing the maximum value of the influence factor weights.
It should be noted that, for the transmission level corresponding to the data to be transmittedThe higher the value, the higher the transmission priority of the data. For device weightsThe device weights may be assigned based on the type, function, criticality, or other relevant factors of the device. For the total weight of the deviceThe normalization factor is the sum of all the equipment weights or a preset fixed value, and is used for adjusting the influence of the equipment weights in the formula so as to ensure that the equipment weights are in a reasonable range. For project influencing factorsFor representing the impact of a particular item on the priority of delivery, the item impact factor may be adjusted based on the urgency, importance, customer demand, or other relevant factors of the item. For the proportion of the amount of data sentThe proportion of the transmitted data quantity of the current project to the total data quantity of the project is represented, and the progress condition of the project is reflected. Finally, weighting values for other influencing factors besides equipment and project factorsOther influencing factors besides equipment and project factors are considered, such as timeliness of data, safety requirements and the like, and the value can be adjusted according to actual conditions.
S403, prioritizing all data to be transmitted according to the transmission level and the emergency degree selection command.
In the embodiment of the invention, when the internet of things equipment generates the data transmission command by itself, the data transmission command comprises data to be transmitted and incidental information, the incidental information comprises equipment information and item information, the equipment information can be equipment names and equipment numbers, the item information is the item names of the data, such as strength inspection data, welding parameter data and the like, and then the equipment information and the item information are input into an equipment transmission level library.
As shown in fig. 4, as a preferred embodiment of the present invention, the step of prioritizing all data to be transmitted according to a transmission level and an emergency degree selection command specifically includes:
S4031, uniformly converting the transmission level and the selected emergency level into priority levels, so that each data to be transmitted corresponds to one priority level;
in step S4031, the calculation formula of the priority level is expressed as:
，
Wherein, Indicating the priority level of the data to be transmitted,Indicating the selected degree of urgency.
Additionally, for a selected degree of urgency,Is a numerical value, which can be assigned according to the actual situation, and the higher the degree of emergency, the larger the value. For the followingIn part, by performing a nonlinear transformation on the transmission level, its impact on the priority level is adjusted. Here, the indexMeaning that as the transmission level increases, its impact on priority level increases, but the speed increase is slightly slowed down.
For the followingA section that nonlinearly converts the influence of the degree of urgency by a natural logarithmic function; when the degree of emergency is low, the influence on the priority level is small; as the degree of urgency increases, its impact on priority levels increases gradually, with the addition of 1 being done to ensure that the value inside the logarithmic function is always greater than 0.
Further, for the case ofA section that considers the combined influence of the degree of urgency and the transmission level; when the degree of urgency is high, the section significantly increases the priority level even if the transmission level is low. Meanwhile, the transmission level in the denominator plays a certain role in adjusting, and extreme values are prevented from occurring when the transmission level is low and the emergency degree is high.
S4032, arranging all the data to be transmitted according to the priority levels, and transmitting the data simultaneously when the priority levels of the data to be transmitted are the same.
In the embodiment of the invention, before formally arranging the data to be transmitted, the transmission level and the selected emergency degree are uniformly converted into the priority level, the conversion relation between the transmission level and the priority level and the conversion relation between the emergency degree and the priority level are required to be formulated in advance, finally, all the data to be transmitted can be arranged according to the priority level, and when the priority levels of the data to be transmitted are the same, the data to be transmitted are transmitted simultaneously, and the transmission sequence is not distinguished.
As shown in fig. 5, as a preferred embodiment of the present invention, the method further includes:
S501, determining the latest starting transmission time of each data to be transmitted according to the transmission level and the selected emergency degree;
In step S501, the calculation formula of the latest start transmission time of the data to be transmitted is expressed as:
，
Wherein, Represents the latest start transmission time of data to be transmitted,Representing a reference time.
As a supplementary explanation, forAnd a section that comprehensively considers the transmission level and the degree of urgency. When the degree of urgency is low, in the denominatorThe term impact is smaller and the transmission level has a larger impact on the latest start transmission time. Along withThe denominator becomes larger, thereby reducing the impact of the transmission level on the latest start transmission time, reflecting the need that urgent data should be transmitted faster.
In addition, forThe part is a Sigmoid function transformation based on the degree of urgency, which is used for mapping the degree of urgency between 0 and 1 in a nonlinear manner. When the degree of emergency is low, the function value is close to 0; as the degree of urgency increases, the function value gradually approaches 1, and the transformation can more finely characterize the effect of the degree of urgency on the latest start transmission time.
S502, detecting a transmission state of data to be transmitted, wherein the transmission state is that transmission is performed or not performed yet;
and S503, when the latest starting transmission time arrives and the transmission state is that the transmission is not performed, the data to be transmitted is transmitted.
In the embodiment of the present invention, it is easy to understand that, each time a data transmission command is received, the previous data to be transmitted may be rearranged, if the priority level of the data to be transmitted is low, it may not be possible to start the data transmission operation for a long time, so that the latest start transmission time, for example, the latest start transmission time corresponding to the transmission level of four levels is 20 minutes, which is set in advance for each transmission level and the degree of urgency, is required.
