Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention discloses a communication protocol conversion method, including:
step S01: judging whether an instruction for converting a first communication protocol into a second communication protocol is received, wherein transmission types of various items of data accessed to the first communication protocol are not uniform; when the instruction is received, the flow proceeds to step S02, otherwise, the process loops to step S01.
Specifically, the transmission type of the data accessed to the first communication protocol reflects a manner in which the data is transmitted after the data is accessed to the first communication protocol. The transmission type comprises a plurality of attribute items, such as transmission modes, transmission basic units and the like, and different attribute items classify the transmission type according to different characteristics. Taking a data access communication protocol Modbus in a certain scene as an example, distinguishing the data access communication protocol Modbus according to transmission modes, wherein the transmission types of the data are divided into a polling mode, a circular uploading mode and a displacement uploading mode; the transmission types of data are classified into bit-wise transmission and value-wise transmission, which are distinguished by a transmission basic unit. The attribute values of the same item of data under the same attribute item are unique.
The transmission types of the data accessed to the first communication protocol are not uniform, and the fact that at least one item of data in the data accessed to the first communication protocol has an attribute value different from that of other data on at least one attribute item of the transmission type is meant. Still taking the scenario of data access to Modbus in the foregoing as an example, assume that four items of data, including voltage, current, time and power on/off, are accessed to Modbus in the current scenario, where the transmission type of the voltage data is polling mode + bit-wise transmission, the transmission type of the current data is polling mode + value-wise transmission, the transmission type of the time data is polling mode + bit-wise transmission, and the transmission type of the power on/off data is cyclic upload mode + bit-wise transmission, only the transmission types of the voltage data and the time data are the same, so the transmission types of the four items of data accessed to Modbus are not uniform.
In addition, the transmission types supported by the second communication protocol may or may not be unique.
Step S02: and importing configuration parameters of various items of data accessed to the first communication protocol into the same set, wherein the configuration parameters comprise the transmission type.
Specifically, the data access communication protocol needs to perform parameter configuration, where the configuration parameters at least include a transmission type of the data, parameters describing an actual value of the data, and the like (the parameters describing the actual value of the data include a register address, a coefficient, and the like, for example, if the register value of the data is 123, the coefficient is 0.1, and then the current value of the data is 12.3).
In this embodiment, the importing of the configuration parameters of each item of data accessed to the first communication protocol into the same set means that the configuration parameters of each item of data accessed to the first communication protocol are collected together, so that centralized processing is facilitated, and the collected content (i.e., the set) can be described in a matrix form or other forms. Still taking the scenario that four items of data, namely voltage, current, time and power on/off, are accessed to the Modbus in the foregoing as an example, the configuration parameters of the four items of data are respectively imported into different rows of the same matrix a, and the content format of the matrix a is as follows:
the matrix A is a 4-by-4 matrix, each row sequentially lists the transmission mode, the coefficient, the register address and the transmission basic unit of one item of data, and corresponding values are led into each element of the matrix A. It should be noted that the content format of the matrix a is modified differently according to the specific content of the Modbus, for example, the maximum value and the minimum value may be increased, the data type may be increased, and different configuration parameters such as a unit may be increased.
Step S03: and classifying other configuration parameters of the data in the set according to different transmission types to obtain a plurality of subsets corresponding to a single transmission type.
Specifically, still taking the matrix a obtained in the above scenario as an example, classifying the four items of data, i.e. voltage, current, time and power on/off, of other configuration parameters in the matrix a according to different transmission types, three sub-matrices (i.e. subsets described in the form of matrices) corresponding to a single transmission type are obtained, where the three sub-matrices are: the submatrix a1 for collectively describing coefficients of voltage, time data, and register addresses, the submatrix a2 for describing coefficients of current data and register addresses, and the submatrix A3 for describing coefficients of power on/off data and register addresses. The content formats of a1, a2, A3 are as follows:
a2 ═ coefficient register address
A3 ═ coefficient register address
Assuming that the transmission type of the data is composed of 1 st to nth attribute items, the attribute value of the ith attribute item is called as the ith attribute value, i is 1, 2, 3, …, n is a positive integer greater than or equal to 1, as shown in fig. 2, the step S03 specifically includes:
step S1: classifying other configuration parameters of the data in the set according to different 1 st attribute values to obtain a plurality of subsets;
step S2: according to the difference of the attribute values of the No. 2, continuously classifying other configuration parameters of the data in the subsets obtained by primary classification to obtain a plurality of subsets;
step S3: according to the difference of the 3 rd attribute values, continuously classifying other configuration parameters of the data in the subsets obtained by secondary classification to obtain a plurality of subsets;
… …, and so on;
step Sn: and according to the difference of the nth attribute values, continuously classifying other configuration parameters of the data in the subsets obtained by n-1 times of classification to obtain a plurality of subsets.
For example, still taking the matrix a obtained in the above scenario as an example, when n is 2, the transmission basic unit is defined as the 1 st attribute item, and the transmission mode is the 2 nd attribute item, then the matrix a has two different 1 st attribute values for bit-wise transmission and value-wise transmission, and has two different 2 nd attribute values for polling mode and cyclic uploading mode, then the implementation of the scheme shown in fig. 2 in the current scenario needs to be classified twice: the first classification is based on that the matrix A is firstly classified into two sub-matrices, namely a sub-matrix A4 for simultaneously and intensively describing coefficients of voltage data, time data and startup and shutdown data, register addresses and transmission modes, and a sub-matrix A2 for describing coefficients of current data, register addresses and transmission modes; the secondary classification is to continuously classify the sub-matrix a4 into two sub-matrices a1 and A3, so as to finally obtain sub-matrices a1, a2 and A3.
It can be seen that fig. 2 classifies the set attribute-item-by-attribute-item for each attribute item of a transmission type, so as to obtain a plurality of subsets having the same transmission type.
Step S04: sending the subsets of different transmission types into a conversion channel corresponding to the transmission type; the conversion channel is used for realizing data format conversion under a fixed transmission type.
Specifically, in this embodiment, according to different transmission types, other configuration parameters of each item of data with non-uniform transmission types under the first communication protocol are classified to obtain a plurality of subsets corresponding to a single transmission type, and each subset can be regarded as a communication protocol with a single transmission type, so that, in a general view, the format of data of various transmission types accessed to the first communication protocol is converted into a format agreed under the second communication protocol.
Step S05: sending the signal output by the target conversion channel into a queue corresponding to the target conversion channel; the target conversion channel refers to a conversion channel of which the corresponding transmission type is the same as the transmission type supported by the second communication protocol.
Specifically, in this embodiment, formats of data of various transmission types accessed to the first communication protocol can be converted into a format agreed under the second communication protocol, but the data applicable to the second communication protocol must be data of a transmission type supported by the second communication protocol, so a conversion channel required to be accessed to the queue is further selected according to the transmission type supported by the second communication protocol. Taking the small matrices a1, a2, and A3 classified in the above scenario as an example, assuming that Modbus needs to be converted into another communication protocol IEC104, and the transmission types supported by IEC104 are polling mode and cyclic uploading mode, the conversion channels accessed by the small matrices a1, a2, and A3 are all conversion channels that need to access queues when Modbus is converted into IEC104, that is, target conversion channels.
Step S06: and outputting data by each queue according to the priority to obtain data suitable for the second communication protocol.
Specifically, in order to comply with the output priority of data with different transmission types, in this embodiment, configuration parameters of data output by different target conversion channels are input into different queues, and each queue outputs data according to a set priority, so that data suitable for a second communication protocol is obtained, and thus conversion from a first communication protocol to the second communication protocol is completed.
As can be seen from the above description of the present embodiment, in the present embodiment, various data accessed to the first communication protocol are classified according to different transmission types, each type of data can be regarded as a communication protocol with a single transmission type, and format conversion is performed on each type of data, so that a format of data accessed to the first communication protocol is converted into a format agreed under another communication protocol; and then, outputting the data which is subjected to format conversion and belongs to the transmission type supported by the other communication protocol according to the priority, so that the data suitable for the other communication protocol can be obtained, and the conversion of the communication protocol with multiple transmission types into any other communication protocol is completed.
It should be noted that the communication protocol conversion process disclosed in the above embodiment is reversible, that is, the conversion of the second communication protocol into the first communication protocol can be realized by using the inverse process of the communication protocol conversion process disclosed in the above embodiment. The reverse process is shown in fig. 3 and includes:
step S11: judging whether an instruction for converting the second communication protocol into the first communication protocol is received; the configuration parameters of the data accessed to the second communication protocol comprise transmission types, and the transmission types of the data accessed to the second communication protocol are not uniform; when the instruction is received, the flow proceeds to step S12, otherwise, the process loops to step S11.
Step S12: when the instruction is received, sending other configuration parameters of each item of data into a conversion channel corresponding to the transmission type according to different transmission types; the conversion channel is used for realizing data format conversion under a fixed transmission type.
Specifically, the data accessing the second communication protocol already appoints the output priority of the data with different transmission types, so that other configuration parameters of each item of data accessing the second communication protocol are input into the corresponding conversion channel according to the priority.
Step S13: leading configuration parameters output by the same conversion channel into the same set, and combining the sets into a set containing the transmission types of the data;
step S14: and analyzing the combined set to obtain data suitable for the first communication protocol. The parsing is a form in which values restore data described in the form of a matrix to a message.
Optionally, if the transmission type of the data is composed of a1 st attribute item to an nth attribute item, an attribute value of an ith attribute item is referred to as an ith attribute value, i is 1, 2, 3, …, n, and n is a positive integer greater than or equal to 1, as shown in fig. 4, the combining the sets into one set including the transmission types of the data includes:
step S21: combining the sets with the same value of the nth attribute into a set containing the nth attribute item;
step S22: combining the sets with the same n-1 attribute value in the sets obtained by the primary combination into a set containing the n-1 attribute item;
step S23: combining the sets with the same n-2 attribute value in the sets obtained by the secondary combination into a set containing the n-2 attribute item;
… …, and so on;
step S2 n: and combining the sets with the same 1 st attribute value in the sets obtained by n-1 times of combination into a set containing the 1 st attribute item.
In the above embodiment, taking the inverse process of finally obtaining the sub-matrices a1, a2, and A3 based on the matrix a as an example, that is, in the current scenario, the sub-matrices a1, a2, and A3 need to be combined to obtain the matrix a, the implementation of the scheme shown in fig. 4 needs to be combined twice: the first combination is to combine the sub-matrices a1 and A3 into sub-matrix a4, and the second combination is to combine the sub-matrices a4 and a2 into sub-matrix a.
As can be seen from the above description of the two embodiments, the communication protocol conversion method shown in fig. 1 or fig. 3 can be used to implement conversion from one communication protocol to another, then communication protocol 1, communication protocol 2, communication protocol 3, … …, and communication protocol k are defined to represent k different communication rules, and when communication protocol 1 needs to be converted into communication protocol k, the communication protocol conversion method shown in fig. 1 or fig. 3 can be used to directly perform conversion, or can be indirectly implemented by setting a relay node.
The method is indirectly realized by setting a transfer node, and specifically comprises the following steps: converting the communication protocol 1 into a communication protocol 2; converting communication protocol 2 into communication protocol 3; … …, respectively; converting a communication protocol k-1 into a communication protocol k; any of which is converted into the communication protocol conversion method as shown in fig. 1 or fig. 3. Thus, in the case where the system has been provided with the function of converting communication protocol 1 into communication protocol 2, the function of converting communication protocol 2 into communication protocol 3, … …, and the function of converting communication protocol k-1 into communication protocol k, the conversion of communication protocol 1 into communication protocol k can be realized by calling these functions already provided, without having to recompile the function of converting communication protocol 1 into communication protocol k.
