In the embodiment of the invention, the data types of the data of the internet of things to be transmitted mainly comprise three types of time types, digital types and character strings, so that the coding modes of the data of different types are different, and the data are required to be processed in different modes, thereby improving the security of the encrypted data.
After the encoding is completed, the decoding of the data needs to be performed in an inverse mode according to the encoding mode, the encrypted data is restored to obtain the data of the internet of things to be transmitted, and the restored data of the internet of things to be transmitted needs to be stored in a specific position.
Compared with the prior art, the method for transmitting the data of the internet of things, provided by the embodiment, comprises the following steps: classifying the data of the internet of things to be transmitted according to the data type of the data of the internet of things to be transmitted, which is acquired by the measuring points; coding the data of the internet of things to be transmitted with different data types by adopting different coding modes to obtain coded data; transmitting the coded data to a message queue of a server through a wireless network; and performing inverse operation decoding processing on the coded data received by the server according to the coding mode to obtain the data of the Internet of things to be transmitted. According to the method, the acquired data of the internet of things to be transmitted are divided into different data types, and the data are transmitted after being encoded according to different encoding modes of the data of the internet of things to be transmitted, so that the complexity of data encoding is increased, the risk of decoding the data in the transmission process is reduced, the safety of the data is improved, the data can be restored through inverse operation decoding after the encoded data is received, the acquired data amount and the data compression are not required to be reduced, and the problems of incomplete data and low delay caused by the loss of the data or the compression of the data are avoided.
Referring to fig. 2, fig. 2 is a flow chart of an embodiment of encoding time type data of internet of things to be transmitted according to the present invention, and in some embodiments of the present invention, the data type includes a time type; the method for coding the data of the internet of things to be transmitted with different data types by adopting different coding modes to obtain coded data comprises the following steps:
s201, converting the time type data of the Internet of things to be transmitted in each measuring point into a preset format number;
s202, traversing preset format numbers in the current measuring point to inquire and record the largest preset format numbers;
s203, encoding other preset format numbers according to the maximum preset format number to obtain time encoding data.
In the above embodiment, for the time type data, the change in a time period is generally not large, and the time address is generally increased gradually, and as a preferred embodiment, the present invention adopts Delta coding to code the time type data of the internet of things to be transmitted, and only needs to determine the maximum time data in the time type data of the internet of things to be transmitted of the measuring point.
The preset format number in the invention is a timestamp type number, and the time data in the data of the internet of things to be transmitted is converted into the number to be represented.
And encoding other data through the difference value between the maximum timestamp type number and the other data to obtain time-encoded data, and recovering all the time-type data according to the recorded maximum timestamp type number and the corresponding difference value.
In a specific embodiment of the present invention, the maximum timestamp type number of the data of the internet of things to be transmitted of the time type in the current measurement point is 1696997594023 (2023-10-11-12:13:14.023), then the newly generated data is more time data after the time, for example 2023-10-11-12:13:15.045, compared with the maximum timestamp type number, the time is only 1 second, the time is converted into the timestamp type number and is 1696997595045 and is denoted as t1, if no encoding is performed, 8 bytes are required for one long integer, if incremental encoding is used, the result of t1-t0 is 1022, only one short shaping of 2 bytes is enough, decoding can restore the original data only by adding t0, and the computational cost of encoding and decoding is very small.
Referring to fig. 3, fig. 3 is a schematic flow chart of an embodiment of encoding digital type data of internet of things to be transmitted according to the present invention, and in some embodiments of the present invention, the data type further includes a digital type; the method for coding the data of the internet of things to be transmitted with different data types by adopting different coding modes to obtain coded data comprises the following steps:
s301, traversing the data of the Internet of things to be transmitted of the digital type in each measuring point to determine the maximum digital value and the minimum digital value in the current time window;
s302, dividing the data of the Internet of things to be transmitted, which are of a digital type in a current time window, into first digital type data and second digital type data according to the difference between the maximum digital and the minimum digital;
s303, encoding the first digital type data by utilizing a univariate linear regression algorithm to obtain first digital encoded data;
s304, the second digital type data is encoded by utilizing a principal component analysis algorithm to obtain second digital encoded data.
In the above embodiment, most of the data collected by the internet of things are digital, and are also the main data types for determining the data coding performance. The collected digital type data may have larger or smaller change, and the digital type data is conveniently encoded by setting a digital data change threshold value to judge.
In the invention, the maximum number max and the minimum number min of the digital type data are searched in a time window, and as a preferred embodiment, the digital data change threshold value is 65535, when the max-min is less than 65535, that is, the data change range is not more than two bytes, the data change of the measuring point can be considered as not large, the data is the first digital type data, and otherwise, the data change of the measuring point is the second digital type data.
The way in which the first digital type data and the second digital type data are encoded is different, and the invention needs to encode them separately to obtain two kinds of digitally encoded data.
Referring to fig. 4, fig. 4 is a flowchart of an embodiment of step S303 in fig. 3, where in some embodiments of the present invention, encoding the first digital type data by using a univariate linear regression algorithm to obtain first digital encoded data includes:
s401, taking serial numbers of first digital type data as input, and taking the first digital type data as output to establish a linear function;
s402, encoding the first digital type data by using a linear function to obtain first digital encoded data.
In the above embodiment, the first digital type data with small variation of the sample time window is screened, and many data with time variation can be changed slowly or even without variation under the condition of small time span, and Delta coding can still be used for the data.
Taking a serial number of the first digital type data as an input x 0 ～x n Taking the first digital type data as output y 0 ～y n Fitting a linear function y=ax+b by using (x, y) as a training set and a univariate linear regression algorithm, wherein a, b are coefficients, the linear function reflects the data change trend of the measuring point in a short time, the first digital type data is encoded by the linear function to obtain first digital encoded data, and the last serial number x of the sample can be used n The value calculated as a parameter input to this linear function is taken as the initial value of the next Delta code.
Referring to fig. 5, fig. 5 is a flowchart of an embodiment of step S304 in fig. 3, where in some embodiments of the present invention, encoding the second digital type data by using the principal component analysis algorithm to obtain second digital encoded data includes:
s501, determining key measuring points in second digital type data by using a principal component analysis algorithm;
s502, determining machine learning models of all measuring points through key measuring points;
s503, encoding the second digital type data according to the machine learning model to obtain second digital encoded data.
In the above embodiment, when the data change is relatively large, the conventional Delta coding is not suitable, and it is very difficult to compress each piece of data in real time without using a batch compression algorithm, the method of reducing the data of the transmission measurement point by using a machine learning algorithm to realize data compression only retains the key measurement point, and the method of implementing decoding reduction by using a prediction model without the key measurement point, so that the amount of the transmitted data can be greatly reduced.
That is, at the same time point, the temperature sensors at different positions may not change much when the distance is not large, so that only the temperature data of one position needs to be found, other temperatures can be predicted by a prediction model, or, the data of different measuring points have association relationship, such as the speed and the fuel consumption of the vehicle, the two are associated, the fuel consumption can be calculated by the speed, and only the speed measuring point needs to be sent. The process is divided into two steps, namely, firstly finding out which are key measuring points, and then finding out the prediction models of other non-key measuring points.
Firstly, a key measuring point is found through a machine learning principal component analysis algorithm, and the number of samples is assumed to be m. The data of each dimension in the sample is first centralized, the average value is subtracted from each sample so that the average value of each dimension of the sample is 0, and then the input sample X is calculated i And (3) carrying out singular value decomposition on the covariance matrix C of m, obtaining the eigenvalue and eigenvector of C, and selecting eigenvectors corresponding to the first L largest eigenvalues as mapped base vectors, wherein L is more than 0 and less than or equal to min (m, n). L is the number of measurement points to be reserved, for example, 10 measurement points, the compression rate is expected to be 50%, then 5 measurement points need to be reserved, and L is 5. The first L eigenvalues then form the key points needed.
And establishing a machine learning model for restoring all the measuring points through the key measuring points. Because of limited terminal performance, sample data are not large, and data with various characteristics need to be adapted, an efficient and widely applicable algorithm needs to be selected, and as a preferred embodiment, a random forest algorithm is used in the invention.
Referring to fig. 6, fig. 6 is a schematic flow chart of an embodiment of encoding data of an internet of things to be transmitted with a character string type according to the present invention, and in some embodiments of the present invention, the data type further includes the character string type; the method for coding the data of the internet of things to be transmitted with different data types by adopting different coding modes to obtain coded data comprises the following steps:
s601, traversing all character string types in the measuring points to be transmitted of the Internet of things data;
s602, establishing a conversion dictionary table according to the to-be-transmitted internet of things data of the character string type in a preset system;
and S603, carrying out coding processing on the data of the internet of things to be transmitted according to the conversion dictionary table to obtain character string coding data.
In the above embodiment, for the data of the character string type, the internet of things data is of the tag type, and dictionary coding may be used. The method and the device have the advantages that specific codes are set for the character strings to represent, original character strings are not used directly, all character string types of the to-be-transmitted internet of things data in the measuring points are traversed to determine which character string data appear, and in the method and the device, a conversion dictionary table is built for the character string types of the to-be-transmitted internet of things data by adopting binary system, so that the to-be-transmitted internet of things data is coded, and the character string coded data are obtained.
In one embodiment of the invention, the following strings are compressed red, yellow, black, green, white, and words are lexicographically encoded with binary digits in the order in which they appear: blank 0; red 1; yellow 10; black 11; green 100; white 101; such a word occupies at most 3 bits and the most frequently occurring word red occupies only 1 bit.
In some embodiments of the present invention, classifying data of the internet of things to be transmitted according to a data type of the data of the internet of things to be transmitted acquired by a measurement point includes:
caching the data of the internet of things to be transmitted, which are acquired in the same time window;
and classifying the data of the Internet of things to be transmitted when the cached data quantity exceeds a preset data quantity threshold value.
In the above embodiment, when the data amount exceeds the preset data amount threshold, the data in one time window is buffered, and considering that the performance of the terminal device is limited, as a preferred embodiment, a model of sample data with the preset data amount threshold set to about ten thousand is usually used to achieve a better effect.
All the data of the internet of things to be transmitted are required to be classified, and the data are mainly classified into time type data, digital type data and character string type data.
It should be noted that, in the decoding process, only the inverse operation of the encoding process is needed to be performed.
In order to better implement the method for transmitting data of the internet of things in the embodiment of the present invention, referring to fig. 7 correspondingly on the basis of the method for transmitting data of the internet of things, fig. 7 is a schematic structural diagram of an embodiment of a device for transmitting data of the internet of things provided by the present invention, and the embodiment of the present invention provides a device 700 for transmitting data of the internet of things, including:
