[0043] To make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0044] Reference Figure 1 , shows a flow chart of the steps of a communication protocol development method provided by an embodiment of the present invention, the method may include the following steps:

[0045] Step 101, when detecting receiving a communication protocol development instruction, encapsulating a target communication interface according to a predefined communication interface standard, wherein the target communication interface is determined based on the communication protocol development instruction, and the predefined communication interface standard includes a physical parameter definition, a communication protocol, and a communication interface command set;

[0046] Furthermore, the physical parameter definition in the predefined communication interface standard includes a predefined hardware connection mode corresponding to the target communication interface.

[0047] Furthermore, the communication protocol in the predefined communication interface standard includes a network layer protocol.

[0048] Furthermore, the communication interface command set in the predefined communication interface standard includes operation commands supported by the target communication interface.

[0049] It should be noted that in the embodiments of the present application, the user only needs to focus on the problems to be solved by the protocol during the process of developing the protocol, namely, the application layer protocol, data specifications and the definition of the device address provided. The underlying protocol calls the encapsulated native communication library, which can realize the development of most industrial communication protocols.

[0050] Therefore, firstly, a communication protocol development instruction sent by a user is received, that is, when the communication protocol development instruction is detected, the target communication interface is encapsulated according to a predefined communication interface standard.

[0051] Specifically, it defines and encapsulates the communication interface standard (protocol stack basic communication library). The communication interface standard is the hardware protocol of communication, which provides mechanical, hardware, electrical, and functional characteristics and procedures. At the same time, it defines the connection method of the transmission medium and the network interface and the method of sending and receiving data. For example, the serial data interface RS485 / RS232, Ethernet data interface, etc.

[0052] Among them, the pre-defined communication interface standards mainly include the following parameters:

[0053] Physical parameter definition: defines the hardware connection method of the interface, such as plug type, pin assignment, electrical characteristics (voltage, current, etc.);

[0054] Communication protocol: encapsulate common network layer protocols, such as TCP / IP, UDP, serial communication protocols, etc., and clarify their parameters and rules;

[0055] Communication interface command set: Determine the various operation commands supported by the target communication interface and their formats and meanings.

[0056] Step 102: encapsulate the first communication device and the second communication device according to a transmission standard and / or a data format of a predefined communication protocol, wherein the first communication device and the second communication device are determined based on the communication protocol development instruction.

[0057] Further, encapsulating the first communication device and the second communication device according to the data format of the predefined communication protocol includes:

[0058] The first communication device and the second communication device are encapsulated according to a data encoding method and a data structure in a data format of a predefined communication protocol.

[0059] Furthermore, the transmission standard of the predefined communication protocol includes at least one of message type, data content specification, data transmission order, data length indication, verification mechanism, error handling rules, flow control strategy, congestion control strategy, time information, upper layer application interface connection rules and data security strategy.

[0060] It should be noted that in the embodiments of the present application, the transmission standard and data format of the communication protocol are defined and encapsulated, that is, the communicating parties must make unified settings for the communication data transmission method, the transmitted data length, the verification method and the transmission rate, so as to ensure the correctness of the communication between the two parties.

[0061] The transmission standards and / or data formats of the predefined communication protocols mainly include the following aspects:

[0062] Data format: clarify the data encoding method, such as binary, ASCII, etc., and the basic structure of the data, such as field division, length, etc.;

[0063] Message type: distinguish messages with different functions, such as request messages, response messages, status messages, etc., and give them specific identifiers;

[0064] Data content specification: specifies in detail the meaning, value range and constraints of each field;

[0065] Data transmission order: Determine the order in which data is sent and received during the transmission process;

[0066] Data length indication: contains information indicating the length of each data unit, which facilitates accurate processing by the receiver;

[0067] Verification mechanism: Use appropriate verification algorithms, such as parity check, CRC check, etc., to ensure data integrity;

[0068] It should be noted that in the embodiments of the present application, a suitable verification algorithm, such as parity check, CRC check, etc., is adopted to ensure data integrity.

[0069] For example, CRC checksum: after K bits of information code, R bits of checksum are spliced, and the entire code length is N bits. Therefore, this code is also called (N, K) code. For a given (N, K) code, it can be proved that there is a polynomial G(x) with the highest power of NK=R. According to G(x), a checksum of K bits of information can be generated, and G(x) is called the generator polynomial of this CRC code. The specific generation process of the checksum is as follows: Assuming that the transmitted information is represented by the information polynomial C(X), shift C(x) left by R bits, it can be represented as C(x)*x to the Rth power, so that R bits will be vacant on the right side of C(x), which is the position of the checksum. The remainder obtained by dividing C(x)*X to the Rth power by the generator polynomial G(x) is the checksum.

[0070] Error handling rules: define the handling methods when encountering transmission errors, such as retransmission, error reporting, etc.

[0071] Flow control strategy and congestion control strategy: determine how to manage data transmission rate to avoid congestion and data loss;

[0072] Time information: such as the interval between message sending and timeout period;

[0073] Upper-layer application interface connection rules: clarify the data format and semantic conversion rules for interaction with upper-layer applications;

[0074] Data security strategy: Incorporate encryption, authentication, authorization and other security measures to protect data security.

[0075] In an embodiment of the present invention, a communication protocol development method is disclosed, the communication protocol development method comprising: in the case of detecting the reception of a communication protocol development instruction, encapsulating a target communication interface according to a predefined communication interface standard, wherein the target communication interface is determined based on the communication protocol development instruction, and the predefined communication interface standard includes a physical parameter definition, a communication protocol, and a communication interface command set; encapsulating a first communication device and a second communication device according to a transmission standard and / or a data format of a predefined communication protocol, wherein the first communication device and the second communication device are determined based on the communication protocol development instruction. In an embodiment of the present invention, the communication protocol development method realizes rapid customized encapsulation of the target communication interface and the communication device through predefined communication interface standards and transmission standards. This method not only optimizes the development process and unifies the development standards, but also significantly improves the reusability of the code, avoids repeated development, and thus greatly improves the development efficiency and system stability of the industrial Internet. Through this method, developers can focus more on innovation and optimization, rather than repetitive work, which effectively promotes the efficient development of the industrial Internet.

[0076] Reference Figure 2 , shows a flow chart of the steps of a communication protocol development method provided by an embodiment of the present invention, the method may include the following steps:

[0077] Step 201, in the case of detecting receiving a communication protocol development instruction, encapsulating a target communication interface according to a predefined communication interface standard, wherein the target communication interface is determined based on the communication protocol development instruction, and the predefined communication interface standard includes a physical parameter definition, a communication protocol, and a communication interface command set;

[0078] Step 202: encapsulate the first communication device and the second communication device according to a transmission standard and / or a data format of a predefined communication protocol, wherein the first communication device and the second communication device are determined based on the communication protocol development instruction.

[0079] Step 203, divide the target address and / or node address range for the first communication device and the second communication device according to the address rule of the predefined communication protocol, wherein the target address includes a network address and / or a device address, and each of the first communication device and each of the second communication devices corresponds to one target address respectively.

[0080] It should be noted that, in the embodiment of the present application, after the interface and protocol encapsulation in steps 201 and 202 are performed, the device address can be further divided based on the device address definition of the communication protocol.

[0081] Specifically, it may include:

[0082] Range division: Divide the device address or node address range to make it readable and understandable so as to accurately identify the communication object, such as using a specific numeric interval to represent the device address;

[0083] Hierarchical structure: A hierarchical address structure can be used, such as dividing the address into a network part and a device part, to better organize and manage a large number of devices;

[0084] Uniqueness: Ensure that each device address is unique to avoid communication confusion caused by address conflicts;

[0085] Reservation and expansion: A certain number of special addresses or reserved addresses are reserved for future expansion or to cope with special circumstances.

[0086] It should be noted that in the embodiment of the present application, the first communication device and the second communication device can act as a receiving end or a sending end. By setting the address, the communication object can be accurately identified to further achieve communication.

[0087] In addition, in the embodiment of the present application, the user only needs to focus on the problems to be solved by the protocol during the development of the protocol, namely, the application layer protocol, data specifications and the definition of the device address provided. The underlying protocol calls the encapsulated native communication library, which can realize the development of most industrial communication protocols. The specific process includes: determining the data specifications, clarifying the basic units of data, such as bytes, words, etc., designing data fields, defining the meaning, length, data type and constraints of each field, and planning the organizational structure of data, such as the format of data packets, the division of data blocks, etc. Define the device address, select the appropriate address representation form, such as digital encoding, binary encoding, etc., determine the range and allocation rules of the address, ensure uniqueness, and consider the hierarchical structure or grouping method of the address for easy management and identification. Write the application layer protocol, design the message type, such as request message, response message, status message, and specify the format and content of the message, including command code, parameters, etc. Define the message interaction process and logic, such as the processing order of requests, exception handling, etc. Integrate the general communication library, integrate the general communication library through the reserved interface, and establish a connection and data interaction channel with the application layer protocol.

[0088] It should be noted that the general communication library contains the main constants, type definitions and function interfaces required for protocol development.

[0089] Among them, constants can include the following:

[0090] TAG_NAME_LEN Maximum length of the point name

[0091] TAG_ADDRESS_LEN Maximum length of the point address

[0092] TAG_DESCRIPTION_LEN Maximum length of the point description string

[0093] GROUP_NAME_LEN Maximum length of group name

[0094] GROUP_INTERVAL_LIMITThe minimum time limit for group data subscription

[0095] NODE_NAME_LEN Maximum length of the node name

[0096] protocol_NAME_LEN Maximum length of the communication library name

[0097] protocol_LIBRARY_LEN Maximum length of the communication dynamic library file name

[0098] protocol_DESCRIPTION_LEN Maximum length of the communication library description string

[0099] The protocol connection status can be expressed as follows:

[0100] typedef enum link_state{

[0101] LINK_STATE_DISCONNECTED=0,

[0102] LINK_STATE_CONNECTING,

[0103] LINK_STATE_CONNECTED,

[0104] }link_state_e;

[0105] Furthermore, for protocol development, the message types of internal communication mainly include REQ_READ_GROUP, RESP_READ_GROUP, REQ_WRITE_TAG, RESP_ERROR, and REQRESP_TRANS_DATA.

[0106] Among them, the REQ_READ_GROUP message indicates a request to read all point data under a group, and its response is returned by a message of the RESP_READ_GROUP type; the REQ_WRITE_TAG message indicates a request to write a point data, and its response is returned with an error code indicated by the RESP_ERROR message.

[0107] Types can include the following:

[0108] typedef struct reqresp_head{

[0109] reqresp_type_e type;

[0110] void* ctx;

[0111] char sender[NODE_NAME_LEN];

[0112] char receiver[NODE_NAME_LEN];

[0113] }reqresp_head_t;

[0114] It should be noted that the above structure types define the header data of the message communication within the communication library. In addition, other different communication messages carry different types of data (initialization, error messages, etc.), and each structure type corresponds to the data body of each message type except the header data.

[0115] The interface may include the following:

[0116] struct protocol{

[0117] protocol_common_t common;

[0118] }; typedef struct protocol_group protocol_group_t;

[0119] typedef void(*protocol_group_free)(protocol_group_t*pgp);

[0120] struct protocol_group{

[0121] char*group_name;

[0122] UT_array*tags;

[0123] void*user_data;

[0124] protocol_group_free group_free;

[0125] };

[0126] typedef struct protocol_intf_funs{

[0127] protocol_t*(*open)(const protocol_callbacks_t*callbacks);

[0128] int(*close)(protocol_t*protocol);

[0129] int(*init)(protocol_t*protocol);

[0130] int(*uninit)(protocol_t*protocol);

[0131] int(*start)(protocol_t*protocol);

[0132] int(*stop)(protocol_t*protocol);

[0133] int(*config)(protocol_t*protocol,config_t*configs);

[0134] int(*request)(protocol_t*protocol,reqresp_head_t*head,void

[0135] *data);

[0136] union{

[0137] struct{

[0138] int(*validate_tag)(protocol_t*protocol,datatag_t

[0139] *tag);

[0140] int(*group_timer)(protocol_t*protocol,protocol_group_t

[0141] *group);

[0142] int(*write_tag)(protocol_t*protocol,void*req,

[0143] datatag_t*tag,value_u value);

[0144] }driver;

[0145] };

[0146] }protocol_intf_funs_t;

[0147] It should be noted that, in the embodiment of the present application, plugin_intf_funs_t indicates that the structure type defines the interface function of the protocol; open indicates opening the protocol, generally allocating memory for the protocol; close indicates closing the protocol, generally releasing the protocol memory; init indicates initializing the protocol; uninit indicates the opposite of initialization; start indicates starting the protocol, generally connecting the device and setting the connection status to connected; stop indicates stopping the protocol, generally closing the device connection and setting the connection status to disconnected; config indicates configuring the protocol, such as configuring the device address, port number, etc.; request indicates the message request interface; driver indicates the southbound protocol-specific interface; -validate_tag indicates point verification, such as address format and data type verification; -group_timer indicates the group timer callback function, which is used to be called periodically when the protocol is subscribed; -write_tag indicates point data.

[0148] The following is a protocol development process using modbus as an example:

[0149] First, the entrance:

[0150] struct protocol{

[0151] protocol_common_t common;

[0152] conn_t*conn;

[0153] modbus_stack_t *stack;

[0154] void *plugin_group_data;

[0155] uint16_t cmd_idx;

[0156] event_io_t*tcp_server_io;

[0157] int client_fd;

[0158] events_t *events;

[0159] };

[0160] The above defines the struct protocol structure of the modbus_tcp protocol. The first member is common of the protocol_common_t type, and the other members are necessary data to implement the protocol functions, such as TCP connection.

[0161] Among them, the interface of the protocol is given by the following structure:

[0162] static const protocol_intf_funs_t plugin_intf_funs={

[0163] .open=driver_open,

[0164] .close=driver_close,

[0165] .init=driver_init,

[0166] .uninit=driver_uninit,

[0167] .start=driver_start,

[0168] .stop=driver_stop,

[0169] .config=driver_config,

[0170] .request = driver_request,

[0171] .driver.validate_tag=driver_validate_tag,

[0172] .driver.group_timer=driver_group_timer,

[0173] .driver.write_tag=driver_write,

[0174] }

[0175] At this point, the entry point of the protocol is basically there. The following is to implement the above interface functions, such as the open function:

[0176] static protocol_t*driver_open(const adapter_callbacks_t*callbacks)

[0177] {

[0178] protocol_t*protocol=calloc(1,sizeof(protocol_t));

[0179] protocol_common_init(&plugin->common);

[0180] protocol->common.adapter=adapter;

[0181] protocol->common.adapter_callbacks=callbacks;

[0182] protocol->common.link_state=

[0183] protocol_LINK_STATE_DISCONNECTED;

[0184] return plugin;

[0185] }

[0186] The open interface of the modbus_tcp protocol is implemented by the driver_open function. It can be seen that the first step of the driver_open function is to allocate memory for the protocol, and then call protocol_comm on_init to initialize the common member.

[0187] Next, implement the interface functions one by one according to the specific functions and rules of the protocol.

[0188] The communication protocol development method in the embodiment of the present invention realizes the rapid customized encapsulation of the target communication interface and communication equipment through the predefined communication interface standard and transmission standard. This method not only optimizes the development process and unifies the development standards, but also significantly improves the reusability of the code and avoids repeated development, thereby greatly improving the development efficiency and system stability of the industrial Internet. Through this method, developers can focus more on innovation and optimization rather than duplication of work, which effectively promotes the efficient development of the industrial Internet.

[0193] Step 304: encapsulate the first communication device and the second communication device according to a transmission standard and / or a data format of a predefined communication protocol, wherein the first communication device and the second communication device are determined based on the communication protocol development instruction.

[0194] The communication protocol development method in the embodiment of the present invention realizes the rapid customized encapsulation of the target communication interface and communication equipment through the predefined communication interface standard and transmission standard. This method not only optimizes the development process and unifies the development standards, but also significantly improves the reusability of the code and avoids repeated development, thereby greatly improving the development efficiency and system stability of the industrial Internet. Through this method, developers can focus more on innovation and optimization rather than duplication of work, which effectively promotes the efficient development of the industrial Internet.
