[0055] The core of this application is to provide a data communication method, which can effectively improve the compatibility of data communication technology to support different types of communication equipment and thus realize data communication; another core of this application is to provide a data communication device, an electronic device and a computer-readable storage medium, all of which have the above-mentioned beneficial effects.

[0056] In order to describe the technical solutions in the embodiments of the present application more clearly and completely, the technical solutions in the embodiments of the present application will be introduced below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0057] An embodiment of the present application provides a data communication method.

[0058] First, please refer to Figure 1 , Figure 1A structural diagram of a data communication system provided by the present application, the data communication system includes a control system 100 and a target device 200, the control system 100 is connected to the target device 200, wherein the target device 200 can be different types of communication devices, such as a CAN device based on CAN communication and / or an Ethernet device based on Ethernet communication, so that the control system 100 can be compatible with different types of communication devices to achieve data communication with different types of communication devices. The data communication method provided in the embodiment of the present application is applied to the control system 100. It should be noted that the type and quantity of the target device 200 do not affect the implementation of the present technical solution, and can be deployed by technical personnel according to actual needs, and the present application does not limit this.

[0059] For further information, please refer to Figure 2 , Figure 2 This is a flow chart of a data communication method provided in the present application. As mentioned above, the data communication method is applied to a control system in a data communication system and may include the following S101 to S103.

[0060] S101: Acquire available communication channels in the target device according to the communication instruction, where the available communication channels include communication channels of each CAN device and / or communication channels of each Ethernet device;

[0061] This step aims to achieve the acquisition of available communication channels in the target device. The target device is a communication device that needs to communicate data with the control system. The user selects and determines from multiple communication devices according to actual needs. The available communication channels are the communication channels available for use in the target device (except abnormal communication channels, occupied communication channels, etc.), such as the available communication channels of each CAN device and / or the available communication channels of each Ethernet device.

[0062] Among them, the operation of acquiring the available communication channels in the target device responds to the communication instruction, which is a data instruction for starting data communication, and can be initiated by the user through the host computer. For example, the control system is connected to the host computer, and human-computer interaction is realized through the host computer. The user initiates the communication instruction through the host computer and sends it to the control system, so that the control system responds to the communication instruction to collect all the available communication channels in the target device and feeds back to the host computer for user selection.

[0063] S102: Determine a target communication channel among all available communication channels;

[0064] This step aims to determine the target communication channel, which is the communication channel used to realize data communication between the control system and the target device. As mentioned above, after obtaining all available communication channels in the target device, the control system can feed back the channel information of all available communication channels to the host computer for user selection. Here, the user can select through a visual display method. Therefore, the user can select the communication channel that currently needs to communicate data as the target communication channel in the host computer display page.

[0065] Therefore, in a possible implementation manner, the above-mentioned determination of the target communication channel among all available communication channels may include the following steps:

[0066] Upload the channel information of all available communication channels to the host computer;

[0067] Get the selection instructions about all channel information in the host computer;

[0068] Determine target channel information according to the selection instruction;

[0069] The target communication channel is determined according to the target channel information.

[0070] The selection instruction is an instruction for selecting a target communication channel from all available communication channels, and is used to indicate the target channel information of the target communication channel selected by the user, thereby realizing the determination of the target communication channel.

[0071] It is understandable that each communication device generally provides multiple communication channels. Therefore, the above channel information may include relevant information of the communication device to which the corresponding communication channel belongs (such as device name, device manufacturer, device ID, etc.) and relevant information of the communication channel itself (such as channel name, channel number, etc.). Obviously, the channel information is similar to the identification information of the communication channel. Different communication channels correspond to different channel information, which is convenient for users to select the target communication channel and for the control system to determine the target communication channel.

[0072] S103: Perform data communication with the target device through the target communication channel.

[0073] This step is intended to achieve data communication. Specifically, after determining the target communication channel, the corresponding device connection port can be called to establish a connection relationship with the target device to which it belongs through the target communication channel, thereby achieving data communication between the control system and the target device based on the target communication channel, including data sending operations and data receiving operations (corresponding to the data message sending and receiving operations in the following embodiments).

[0074] It can be seen that the data communication method provided in the embodiment of the present application provides a control system that is compatible with different types of communication devices to achieve data communication. The control system is connected to different types of communication devices. The communication devices may include CAN devices based on CAN communication and / or Ethernet devices based on Ethernet communication. During the data communication process, the control system can obtain all available communication channels in the specified target device for user selection. After selecting and determining the target communication channel, the control system can establish a communication connection relationship with the target device through the target communication channel, thereby achieving data communication with the target device based on the target communication channel. Obviously, this implementation method can be compatible with different types of communication devices at the same time, including CAN devices and Ethernet devices, effectively improving the compatibility of data communication technology.

[0075] Based on the above embodiments:

[0076] In one embodiment of the present application, the data communication with the target device through the target communication channel may include the following steps:

[0077] In response to the message receiving request, receiving a first message sent by the target device through the target communication channel, and uploading the first message to the host computer;

[0078] In response to the message sending request, a second message sent by the upper computer is received, and the second message is sent to the target device through the target communication channel.

[0079] The embodiment of the present application provides a method for realizing data communication between a control system and a target device based on a target communication channel. It is understandable that data communication includes the reception and transmission of data messages. Therefore, when a message reception request is received, a first message sent by the target device can be received through the target communication channel, and uploaded to the host computer for the user to view. When a message transmission request is received, the second message sent by the host computer can be obtained and sent to the target device through the target communication channel. Among them, the message reception request can respond to the reception information of the first message, and the first message comes from the target device. The message transmission request can respond to the reception information of the second message, and the second message comes from the host computer. It should be noted that the above-mentioned "first" and "second" are only used to distinguish between the received data message and the data message to be sent, and no other restrictions are made.

[0080] In one embodiment of the present application, uploading the first message to the host computer may include the following steps:

[0081] Obtaining upload configuration information about the first message in the host computer;

[0082] Determining an upload mode of the first message according to the upload configuration information;

[0083] Reassemble the first message according to the upload mode to obtain a first reassembled message;

[0084] Upload the first reassembled message to the host computer.

[0085] The embodiment of the present application provides a method for uploading a first message to a host computer. Specifically, the user can pre-configure the upload mode of the first message according to actual needs, and the configuration process can be implemented based on configuration information, that is, the user can pre-configure parameters in the host computer to generate upload configuration information about the first message, and the upload configuration information is used to indicate various types of configuration information of the first message during the upload process, such as the message format of the first message during the upload process (which can be any type of data format), the upload method (which can include but is not limited to block upload, block upload data block size, real-time upload, scheduled upload, scheduled upload interval, etc.), etc.

[0086] Therefore, the control system can obtain the upload configuration information pre-set by the user from the upper computer, and determine the upload mode of the first message based on the upload configuration information, so as to reorganize the first message according to the upload mode to obtain the reorganized first message, that is, the above-mentioned first reorganized message, and finally upload the first reorganized message to the upper computer to realize the uploading of the first message.

[0087] In one embodiment of the present application, sending the second message to the target device through the target communication channel may include the following steps:

[0088] Obtaining the sending configuration information about the second message in the host computer;

[0089] Determining a sending mode of the second message according to the sending configuration information;

[0090] Reassembling the second message according to the sending mode to obtain a second reassembled message;

[0091] The second reassembled message is sent to the target device through the target communication channel.

[0092] The embodiment of the present application provides a method for implementing sending a second message to a target device. Specifically, the user can pre-configure the sending mode of the second message according to actual needs, and the configuration process can also be implemented based on configuration information, that is, the user can pre-configure parameters in the host computer to generate sending configuration information about the second message, and the sending configuration information is used to indicate various types of configuration information of the second message during the sending process, such as the message format of the second message during the sending process (which can be any type of data format), the sending mode (which can include but is not limited to block sending, the size of the data block sent in blocks, real-time sending, scheduled sending, the interval time of scheduled sending, etc.), etc.

[0093] Therefore, the control system can obtain the sending configuration information preset by the user from the upper computer, and determine the sending mode of the second message based on the sending configuration information, so as to reorganize the second message according to the sending mode to obtain the reorganized second message, that is, the above-mentioned second reorganized message, and finally send the second reorganized message to the target device through the target communication channel to realize the sending of the second message.

[0094] It should be noted that the above-mentioned upload configuration information and sending configuration information correspond to the communication mode of the data message, and the two can be the same or different, and can be set by the user according to actual needs, and this application does not limit this. In addition, since the configuration information (upload configuration information and sending configuration information) sets the message format, communication mode (upload mode and sending mode) of the data message (first message and second message) in the communication process (upload and send), the reorganization operation of the data message includes but is not limited to multi-frame splitting, LEN byte update, flow control frame definition, data block definition, interval time definition and other operations.

[0095] It can be understood that, through the above two embodiments, in the face of different types of communication devices, it is still possible to achieve a unified format for sending and receiving messages during the communication process, which is more convenient for subsequent users to view and manage communication data.

[0096] In one embodiment of the present application, the data communication method may further include the following steps:

[0097] Obtaining log configuration information about sent and received messages in the host computer, where the sent and received messages include a first message and a second message;

[0098] Determine the preset log format according to the log configuration information;

[0099] Read the log data corresponding to the sent and received messages;

[0100] Convert the data format of log data to the preset log format.

[0101] It is understandable that in order to facilitate exception tracing and data review, log recording is generally performed during the data communication process. However, due to the different types of communication equipment, the format of the log information recorded during the data communication process may also be different. In this regard, an embodiment of the present application provides a method for implementing a unified log format.

[0102] Specifically, the user can pre-set the log configuration information about the sent and received messages (i.e., the first message and the second message) according to actual needs, which is used to indicate the log format specified by the user, i.e., the preset log format, so that the control system can read the log data generated during the data communication process and convert its data format into the preset data format. Obviously, based on this implementation, in the face of different types of communication equipment, the format of the log data in the data communication process can still be unified, which is more convenient for subsequent users to view and manage the logs.

[0103] In one embodiment of the present application, the data communication method may further include: when a communication completion instruction is received, disconnecting from the target communication channel according to the communication completion instruction.

[0104] The data communication method provided in the embodiment of the present application can further realize the channel disconnection function, that is, after the control system completes the data communication with the target device, it can disconnect from the target communication channel, thereby ending the data communication with the target device, thereby realizing the release of the device communication port and the target communication channel. Of course, it can be reused after the resource release is completed. Among them, the channel disconnection operation can respond to the communication completion instruction, and its acquisition method can refer to the acquisition method of the above-mentioned communication instruction, and the embodiment of the present application will not be repeated here.

[0105] Based on the above embodiments:

[0106] The present application embodiment provides another data communication method, and its implementation process is as follows:

[0107] Step 1: Please refer to Figure 3 , Figure 3 This is a structural diagram of another data communication system provided by this application. The control system can be based on Windows system or Linux system, and the target device can be Ethernet device, CAN device shipped by Vector, CAN device shipped by Zhou Ligong, CAN device shipped by Pcan, other communication devices, etc. On this basis, the user can configure various parameters in the host computer in advance, and the control system can call the channel interface to automatically obtain all available communication channels in the target device. When multiple communication devices are connected at the same time, the channel interface will return an array to the host computer, which stores the channel information of all available communication channels, including but not limited to the communication device name, communication channel name, and communication channel number.

[0108] Step 2: Please refer to Figure 4 , Figure 4This is a schematic diagram of a communication bus processing method provided in the present application. The user selects the target communication channel in the host computer. The control system calls the corresponding driver to connect to the target communication channel according to the target communication channel selected by the host computer. After successful connection, the corresponding driver will be called to perform operations such as bus and cache initialization.

[0109] Step 3: Please refer to Figure 5 , Figure 5 A flow chart of a method for receiving data messages provided in the present application, wherein the host computer calls the message receiving interface to receive data messages (i.e., the first message mentioned above) in real time, and the control system can choose to filter the ID mode or not filter the ID mode (set according to actual needs) in the message receiving mode. Different modes are suitable for host computers with different functions. For example, the host computer with the diagnostic function can filter the ID, but the host computer for message monitoring does not need to filter the ID. In addition, the message receiving interface can support different forms of message receiving modes. When the received data message is single-frame data, the data message can be received in a single-frame format; when the received data message is the first frame data of continuous frame data, the flow control frame can be generated according to the host computer configuration to realize the reception of the data message. Among them, the flow control frame configuration includes data block size configuration, transmission interval time configuration, etc.

[0110] Step 4: Please refer to Figure 6 , Figure 6 A flow chart of a method for sending a data message provided by the present application (with Figure 5 The host computer calls the message sending interface to send a data message (i.e., the second message mentioned above). When sending a data message, it is only necessary to organize the data message to be sent into an array or list, and call the data processing module for processing. Among them, the data processing module can automatically parse and reorganize the incoming data message, and its functions include but are not limited to multi-frame splitting, LEN byte update, flow control frame definition, data block definition, interval time definition, etc. After the data processing is completed, the sending module will call the corresponding communication device interface, reorganize and package the data message and send it, and finally write the sending result into the log.

[0111] Step 5: The host computer can call the log information interface to obtain the current and previous log information, and unify the log format according to the configuration information.

[0112] Step 6: Figure 4 As shown, after the upper computer completes its work, that is, after completing the current data communication, it can call the disconnection interface to disconnect the target communication channel to release the interface, and the released interface can be reused.

[0113] On this basis, please refer to Figure 7 , Figure 7 This is a structural diagram of another data communication system provided by this application, and the functions of each functional module are as follows:

[0114] (1) Configuration module: provides unified configuration information for the host computer to perform parameter configuration.

[0115] (2) Channel module: It uses polling to poll all supported communication devices and the supportable communication channels in each communication device, and returns all available information.

[0116] (3) Connectivity module: supports the host computer to actively connect to communication devices, disconnect communication devices, initialize communication devices, and other operations.

[0117] (4) Sending parsing module: used to automatically parse the array of messages to be sent from the host computer into single-frame or multi-frame formats.

[0118] (5) Sending module: used to call the sending driver interface to send the results of the sending parsing module in sequence.

[0119] (6) Receiving and parsing module: used to parse and reassemble the single-frame or multi-frame messages received by the driver.

[0120] (7) Receiving module: used to continuously receive valid messages and support automatic sending of flow control frames.

[0121] (8) Log module: used to continuously record log information about data messages and unify the log format.

[0122] (9) Data structure reorganization module: used to reorganize parameters and data according to the driver used.

[0123] (10) CAN drive automatic calling module: used to automatically identify and call the communication device and communication channel selected by the host computer.

[0124] It can be seen that the data communication method provided in the embodiment of the present application provides a control system that is compatible with different types of communication devices to achieve data communication. The control system is connected to different types of communication devices. The communication devices may include CAN devices based on CAN communication and / or Ethernet devices based on Ethernet communication.

After selecting and determining the target communication channel, the control system can establish a communication connection relationship with the target device through the target communication channel, thereby achieving data communication with the target device based on the target communication channel.
