Detailed Description
In order to further describe the technical means and effects adopted by the invention to achieve the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects of the system for managing the scheduling data of the used engine oil based on the data monitoring according to the invention in combination with the accompanying drawings and the preferred embodiment. In the following description, different "one embodiment" or "another embodiment" means that the embodiments are not necessarily the same. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
The following specifically describes a specific scheme of the used engine oil scheduling data safety management system based on data monitoring provided by the invention with reference to the accompanying drawings.
Referring to fig. 1, a system block diagram of a system for managing scheduling data of used engine oil based on data monitoring according to an embodiment of the present invention is shown, where the system includes a data acquisition module, a data transmission module and a data encryption storage module, the data acquisition module is used for acquiring scheduling data in a scheduling circulation process of used engine oil, the data transmission module is used for compressing and storing the scheduling data, and specifically includes a scheduling data acquisition module, a length acquisition module, an encoding table acquisition module, a periodic distribution rule module and an encoding transmission module, and the data encryption storage module is used for decoding a received encoding result of a scheduling data sequence and encrypting and storing the decoded scheduling data sequence.
Referring to fig. 2, a system block diagram of a data transmission module of a used engine oil scheduling data safety management system based on data monitoring according to an embodiment of the present invention is shown, where the system includes the following modules:
the scheduled data acquisition module S101 is configured to acquire a scheduled data sequence and all source symbols.
Specifically, a sequence formed by the scheduling data collected in preset time according to the collection sequence is recorded as a scheduling data sequence; the same scheduling data in the scheduling data sequence is recorded as a source symbol, and all the source symbols in the scheduling data sequence are obtained.
And the length obtaining module S102 is configured to obtain a first length and a second length according to a relationship between an average length of two positive integers satisfying the condition and an information entropy of the scheduled data sequence.
It should be noted that, after any one data sequence is subjected to lossless encoding, the average length of the encoding result of each data is not necessarily smaller than the information entropy of the data sequence, which is a unit of information conveyed by the data in the data sequence, that is, the optimal value of the average length of the encoding result of each data in the data sequence is the information entropy of the data sequence, so that the closer the average length of the encoding result of each scheduling data in the scheduling data sequence is to the information entropy of the scheduling data sequence, the higher the data compression efficiency is. Since the average length of the fixed-length code is an integer and the information entropy of the data sequence is not necessarily an integer, the average length of the code result of each schedule data in the schedule data sequence cannot be made closest to the information entropy of the schedule data sequence by the fixed-length code. It is considered that the average length of the indefinite length code may not be an integer, and thus, there is an opportunity to make the average length of the code result of each schedule data in the schedule data sequence closest to the information entropy of the schedule data sequence by the indefinite length code.
It should be further noted that, in this embodiment, all kinds of source symbols in the modulation data sequence are encoded by all binary numbers corresponding to two different lengths, so that the number of binary numbers is required to be greater than or equal to the number of all kinds of source symbols; meanwhile, in order to ensure the decodability of the encoding result, one binary number needs to be randomly selected from all binary numbers corresponding to two different lengths as an identifier, so that the number of binary numbers is required to be reduced by 2 or more and is not less than the number of all source symbols; in order to make the efficiency of the final coding result best, binary numbers with different lengths are allocated to source symbols with different frequencies, so that the average length of the coding result of each scheduling data in the scheduling data sequence is closest to the information entropy of the scheduling data sequence, therefore, when a fixed-length codeword is allocated to the source symbol, a fixed-length codeword with shorter bit length allocated to the source symbol with larger frequency is required, and a fixed-length codeword with longer bit length allocated to the source symbol with smaller frequency is required.
Specifically, counting the frequency of each information source symbol in the scheduling data sequence, obtaining the information entropy E of the scheduling data sequence according to the frequency of all the information source symbols in the scheduling data sequence, and arranging all the information source symbols in the sequence from the large frequency to the small frequency; for meeting the requirementsAnd is also provided withAny two positive integers of (2)Andaccording to the principle that a fixed-length codeword with shorter bit length is allocated to a source symbol with larger frequency and a fixed-length codeword with longer bit length is allocated to a source symbol with smaller frequency, two positive integers are calculatedAndaverage length of (2)Two positive integers with average length closest to information entropy EAndrespectively marked as a first lengthAnd a second lengthThe method comprises the steps of carrying out a first treatment on the surface of the Wherein, two positive integersAndaverage length of (2)The calculation formula of (2) is as follows:
in the method, in the process of the invention,representing two positive integersAndis used for the length of the average of (a),andto meet the requirements ofAnd is also provided withIs a combination of two positive integers of (a),the frequency of the j-th source symbol after sorting is represented, and L represents the number of the source symbols.
It should be noted that, in the process of scheduling data transmission, the larger the loss risk and transmission error rate of the data are due to the greatly increased data amount of the transmitted data, the further the problem of influencing the integrity and accuracy of the received scheduling data is solved. Aiming at the problems that the optimal value of the average length of the coding result of each data in the data sequence is the information entropy of the data sequence, the average length of the fixed-length coding is an integer, and the information entropy of the data sequence is not necessarily an integer, the embodiment obtains the first length and the second length of which the number of corresponding binary numbers is larger than the information source symbol condition and the average length is closest to the information entropy of the scheduling data sequence, codes the scheduling data sequence according to the binary numbers corresponding to the first length and the second length, enables the average length of the coding result of each scheduling data in the scheduling data sequence to be closest to the information entropy of the scheduling data sequence, and improves the data compression efficiency.
And the code table obtaining module S103 is configured to assign binary numbers corresponding to the first length and the second length to the first identifier, the second identifier and all source symbols, and obtain a code table.
Specifically, two identifiers are set, which are respectively: a first identifier and a second identifier; assigning a binary number of length equal to the first length and all 0 to the first identifier, and assigning a binary number of length equal to the second length and all 0 to the second identifier; give the front after sequencingThe method comprises the steps that binary numbers with the length equal to a first length are allocated to each source symbol and recorded as a first source symbol, and the first identifier also belongs to the first source symbol; the remaining source symbols are allocated binary numbers with the length equal to the second length and marked as second source symbols, and the second identifier also belongs to the second source symbols; wherein, the liquid crystal display device comprises a liquid crystal display device,representing the first length. The result of assigning binary numbers to all source symbols and two identifiers is recorded as a code table.
The present embodiment is illustrated by the following examples, which are specifically:
the first source symbol comprises: A. b, C, the second source symbol comprises: D. k, H, L, M, N, R the first identifier isThe second identifier isReferring to fig. 3, a schematic diagram of an encoding table in the present embodiment is shown.

Although the average length of the coding result of each scheduling data in the scheduling data sequence is opportune to be closest to the information entropy of the scheduling data sequence by the variable length coding, the coding of the scheduling data sequence according to binary numbers with different lengths can lead to disordered connection of the binary numbers with different lengths in the coding result, the binary numbers with different lengths cannot be distinguished during decoding, and finally the coding result of the variable length coding cannot be decoded, namely the coding result of the variable length coding cannot be decoded.
It should be further noted that, in order to ensure the decodability of the encoding result of the irregular length encoding, this embodiment attempts to obtain the period and the period distribution rule of the distribution of different source symbols in the scheduling data sequence according to the hiding regularity of the first source symbol (the source symbol corresponding to the binary number of the first length) and the second source symbol (the source symbol corresponding to the binary number of the second length) in the scheduling data sequence, and for the period that does not follow the period distribution rule in the scheduling data sequence, by adding identifiers of different lengths at some positions, all the periods of the scheduling data sequence follow the period distribution rule, so as to ensure the decodability of the encoding result of the irregular length encoding of this embodiment.
