The variable adaptive serial communication method of the embodiment realizes the variable adaptive communication of the data frame by setting the variable adaptive serial communication protocol, the parameter library and the parameter matching process based on the protocol and the parameter library in the receiving system, and when the parameters in the serial communication change according to the change of the design requirement, the parameter change in the serial communication protocol can be realized only by adjusting the content parameters of the communication data frame of one of the receiving system or the sending system or corresponding software, thereby avoiding the larger workload of simultaneously changing the communication protocol and the software by the receiving system and the sending system, ensuring the effectiveness and the convenience of the type of the serial communication transmission parameters, reducing the workload, improving the system maintenance and the adjusting speed, and having better engineering popularization and application values.

As shown in fig. 2, in a preferred embodiment of the present invention, the format of the variable adaptive serial communication protocol specifically includes:
the data frame head SyncWord and the frame check word Checksun are respectively arranged at the frame head and the frame tail;
the data length Number is used for marking the total data Number of data word contained in the current communication protocol;
the data state Status is used for identifying the matching state of the data DataWord and the parameter types in the parameter database;
the position is used for identifying the position of the data DataWord to be matched in the current data frame, specifically, the state of the position is determined by a sending system, if the data DataWord is matched for the first time, traversal of all the data datawords needs to be completed, and at the moment, the position of the next data frame is added with 1; if the sending system only changes the parameter matching of one or more datawords, the position of the next data frame points to the position of the next DataWord needing to be matched, and the parameter matching of the DataWord is completed through one or more data frames.
A data Flag for identifying that the data DataWord in the current data frame corresponds to a grouping category in the parameter base;
the parameter ElementID is used for identifying a corresponding parameter ElementID in the parameter library, and the Position of the parameter in the communication protocol is the Position pointed by the Position;
and the data DataWord is used for identifying the parameter data transmitted in the current data frame.
In this embodiment, the sending system and the receiving system communicate in a format of a variable adaptive serial communication protocol, and identify parameter data in each serial data frame by identifying a data frame header SyncWord, a data length Number, and a frame check word Checksun, where data1 to data n are n parameter data agreed by the sending system and the receiving system together.
In the prior art of communication protocol design for fixing Data frame structure and content, Data 1(Data word1) -Data n (Data word n) are fixed parameters, such as Data 1(Data word1) representing PLA and Data 2(Data word 2) representing NG, and Data 1-Data n are transmitted from a transmitting system to a receiving system according to a communication protocol through communication, and the receiving system receives and identifies corresponding Data for processing.
Due to the requirement of system design, when one Data n +1(Data n +1) is added for transmission or one Data x (Data x) is changed into another parameter, the communication protocol needs to be redefined by the sending system and the receiving system. If the system needs to frequently adjust the parameters in the communication protocol, the software codes of the sending system and the receiving system can only be modified to re-debug the programming, which results in a great increase of the workload.
In the variable adaptive serial port communication protocol of the embodiment, the data1 to the data n are set as adjustable data parameters, communication is realized by adjusting the content of a communication data frame of the sending system or corresponding software, the communication protocol does not need to be redefined, and the workload is effectively reduced.
Specifically, the variable adaptive serial communication protocol is configured as shown in table 1:
TABLE 1
In table 1, the data frame header Sync Word and the frame check Word Checknum are mainly used for parsing the data frame. The data state Status is respectively a value of 0 and a value of 1, wherein 1 represents that the data 1-data n are matched with the data of the parameter database, and the data are transmitted and analyzed according to a communication protocol that the data 1-data n are fixed data frame structures and contents; and 0 represents that the data 1-data n are not matched with the data in the parameter library, and the data can be transmitted and analyzed according to the communication protocol of the fixed data frame structure and the content after the matching is finished.
The data Flag indicates the data type (or multiple types), and represents the parameter type of the parameter library, such as 0 for class i parameter and 1 for class ii parameter, which can reduce the search time of the matching parameter.
The Position indicates the sequence and number of Data Word in the communication protocol, 1 for Position, 2 for Position and … … for Position.
The parameter Element ID represents a corresponding parameter Element ID in a parameter library, and the Position of the parameter in the communication protocol is the Position pointed by the Position. Such as: when the Element ID is 0x3000 and the Position is 1, the parameter ID indicating the Data 1Data Word1 is 0x3000, and when the Position is 2, the parameter ID indicating the Data 2Data Word 2 is 0x 3000.
The Data Word represents the Data to be matched with the parameters in the parameter library.
As shown in fig. 3, in the preferred embodiment of the present invention, the parameter library stores a parameter ElementID and a parameter type corresponding to the parameter ElementID one to one.
In this embodiment, before the sending system and the receiving system perform communication, parameter types that all the sending systems can send to the receiving system through serial communication are agreed, a parameter library is established, the parameter library can be set independently or can be used as a part of the receiving system, a corresponding Element ID is set for each parameter type in the parameter library, the Element ID corresponds to a parameter Element ID in a variable adaptive serial communication protocol, and the Element ID and the parameter types have uniqueness, that is, the Element ID is unique and represents a unique parameter type. Meanwhile, the parameter library also stores the parameter ElementID and the corresponding parameter types in groups according to different parameter types and set rules, and establishes a plurality of parameter lists, so that the searching efficiency is improved.
In a preferred embodiment of the present invention, before the sending system sends the data frame based on the variable adaptive serial communication protocol, the sending system further includes:
establishing a communication relation between a sending system and a receiving system according to the requirement of a serial interface, and configuring port attributes including a baud rate, parity check, a data bit and a stop bit. Thereby making necessary preparation for subsequent communication.
As shown in fig. 4, in a preferred embodiment of the present invention, the receiving system receives the data frame and reads the value of the identifier in the data frame, if it is determined that there is a difference according to the value of the identifier, the receiving system matches the data type in the received data frame with the parameter type in the preset parameter library, and after the matching is completed, the data transmission and analysis processing according to the communication protocol of the fixed data frame structure and content specifically includes the steps of:
if a data packet is sent, receiving an ith data frame;
reading the value of a data state Status in the ith data frame, and judging whether the data in the ith data frame is different from the data in the historical data frame or not according to the value of the data state Status;
if the difference exists, reading the value of the position in the ith data frame, and determining the position of the data DataWord needing to be matched in the current data frame;
reading data DataWord corresponding to the value of the position;
reading a parameter ElementID corresponding to the value of the position in the ith data frame;
searching the parameter type in the parameter library according to the parameter ElementID;
matching data DataWord in the ith data frame with the parameter types in the parameter library;
repeating the steps until the matching of all data DataWord in all data frames is completed;
and after matching, carrying out data transmission and analysis processing according to the communication protocol of the fixed data frame structure and the content.
This embodiment describes a parameter matching process of a receiving system in detail, where the sending system compares data parameters in a data frame that needs to be sent currently with data parameters in a data frame that is sent historically before sending data, if a difference is found, a data state Status in the data frame that needs to be sent currently is set to 0, otherwise, the data state Status is set to 1, and after the receiving system receives the data frame sent by the sending system, the receiving system reads a value of the data state Status, and if the value is 0, the receiving system matches the parameter library, where each frame only matches one data parameter, receives other data frames in sequence, until all data parameters are matched, and after matching is completed, performs parameter analysis or processing according to a communication protocol of a fixed data frame structure and content.
The state of position includes two cases:
for the first matching, traversal of all Data words needs to be completed, each frame only matches one Data parameter, the present embodiment traverses each Data word in the Data frame by using the Data state Status, the position points to the Data word1 first, so as to match the Data word1, and when the next frame, the Data word 2 needs to be matched, so that the position adds 1, takes a value of 2, so as to point to the Data word 2 for matching like a pointer, and so on, until the position is equal to n, the parameter matching including the Data word1 — the Data word n is completed.
When the sending system only changes the parameter matching of one or more data DataWord, the position of the next data frame points to the position of the next data DataWord needing to be matched, and the parameter matching of the data DataWord is completed through one or more data frames.
And when the Data k is matched specifically, the Data k (namely the Data word) and the parameter ElementID corresponding to the value k of the position in the current Data frame are read, then the corresponding parameter X is searched through the parameter ElementID, and after the parameter ElementID is found, the matching of the Data k in the current Data frame is completed. And by circulating the steps, after parameter matching of all the data frames is completed, the receiving system carries out parameter analysis or processing according to the communication protocol of the fixed data frame structure and the content.
It can be understood that, in this embodiment, through the parameter matching process based on the variable adaptive serial communication protocol and the parameter library, the variable adaptive communication of the data frame is realized, when the parameter data in the serial communication changes according to the change of the design requirement, after the parameter data of the data frame is searched and matched with the parameter library in the receiving system, the parameter analysis or processing is performed according to the communication protocol of the fixed data frame structure and content, so as to realize the parameter change in the serial communication protocol, thereby avoiding a large workload when the communication protocol and software need to be changed simultaneously for the receiving system and the sending system, ensuring the validity and convenience of the serial communication transmission parameter type, reducing the workload, and improving the speed of system maintenance and update.
As shown in fig. 5, in a preferred embodiment of the present invention, the receiving system receives the data frame and reads the value of the identifier in the data frame, if it is determined that there is a difference according to the value of the identifier, the receiving system matches the data type in the received data frame with the parameter type in the preset parameter library, and after the matching is completed, the data transmission and analysis processing according to the communication protocol of the fixed data frame structure and content specifically includes the steps of:
if a data packet is sent, receiving an ith data frame;
reading the value of a data state Status in the ith data frame, and judging whether the data in the ith data frame is different from the data in the historical data frame or not according to the value of the data state Status;
if the difference exists, reading the value of the position in the ith data frame, and determining the position of the data DataWord needing to be matched in the current data frame;
reading data DataWord corresponding to the value of the position;
