These drawings are not necessarily drawn to scale. It should be understood that these drawings depict only some embodiments disclosed in accordance with the present application and should not be regarded as limiting the scope of the present application.

[0057] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0058] In the related art, although there are individual solutions that can self-adapt to different protocol types of heterogeneous devices and improve the adaptation efficiency, when facing different types of devices with the same type of protocol or similar devices with different data identifiers for the same type of protocol, situations of misjudgment or protocol parsing errors are likely to occur.

[0059] For example, the Chinese invention patent with the application number 202211323219.6 discloses a method for self - adapting the protocols of Internet of Things devices based on DFS. In this method, the Depth First Search (DFS) algorithm is used as the basic algorithm. Through protocol layering and protocol classification as pruning conditions, device adaptation and parsing are carried out to solve the problem of a large number of heterogeneous device accesses, shorten the search range of protocol types, match the corresponding protocol types, reduce the manual protocol adaptation operations when each device accesses, improve the operation and maintenance efficiency of the software system, and reduce the operation and maintenance costs. Although this method can self - adapt to different protocol types of heterogeneous devices and improve the adaptation efficiency, when facing different types of devices with the same type of protocol or similar devices with different data identifiers of the same type of protocol, misjudgment or protocol parsing errors are likely to occur. Especially when facing serial port protocol devices, this method has a relatively high error rate.

[0060] Based on this, in the technical solution provided in the embodiment of the present application, for the protocol self - adaptation of the application layer in the Open System Interconnect (OSI) model, the Depth Limited Search (DLS) algorithm is used to search and obtain the matching protocol from the protocol library of the data acquisition platform with the least consumption, and the protocol parsing of homogeneous and heterogeneous devices is completed, which can avoid misjudgment or protocol parsing errors, reduce the operations of manual intervention configuration, and reduce the operation and maintenance costs of the data acquisition platform implementation.

[0061] Among them, the DFS algorithm is an algorithm used to traverse or search trees or graphs. The most important algorithm ideas in the DFS algorithm are backtracking and pruning. By circularly pruning all branches and nodes, the final result is obtained. The DLS algorithm is a search algorithm based on the premise of minimum cost or maximum benefit. The DLS algorithm stipulates the maximum depth of the DFS algorithm. When this depth is reached, the search will be abandoned and other branches or nodes will be explored instead, solving the problem of infinite paths.

[0062] Next, the technical solution provided in the embodiment of the present application will be introduced in detail with reference to the accompanying drawings.

[0063] Figure 1 The flowchart showing the method for self - adapting the industrial device protocol according to an embodiment of the present application is as follows. Figure 1 As shown, the method may include the following steps:

[0064] S110. Construct the protocol library of the data acquisition platform.

[0065] In specific implementation, the protocol library may include multiple protocols.

[0066] In one implementation manner, step S110 may include the following steps:

[0067] S111. Construct a number of protocol parameter models according to the message structures of a number of first protocols.

[0068] In specific implementation, the number of first protocols can be protocols commonly used by industrial devices. Among them, the above-mentioned multiple protocols can include a number of first protocols. Among them, the number of first protocols can include but are not limited to: Modbus protocol, DLT645 protocol, OPCUA protocol.

[0069] In specific implementation, the number of protocol parameter models corresponds to the number of first protocols.

[0070] In specific implementation, step S111 can include: extracting the data identifier of any one of the first protocols, and the data identifier includes a start bit, data bits, a check bit, a stop bit, and a data bit pattern; then constructing one of the number of protocol parameter models according to the data identifier of any one of the first protocols. It can be understood that using the start bit, data bits, check bit, stop bit, and data bit pattern of any one of the first protocols as elements to construct any protocol parameter model.

[0071] As an example, the message structure of the data identifier part of any one of the first protocols can be as Figure 2 shown.

[0072] S112. Construct the protocol library according to the number of protocol parameter models.

[0073] That is, the protocol library includes a number of protocol parameter models. It can be understood that any one of the first protocols is entered into the protocol library in the form of the constructed protocol parameter model style.

[0074] In the embodiment of the present application, by executing step S111-step S112, protocols accumulated by industrial devices collected from past projects can be entered into the protocol library based on the protocol parameter models, forming an industrial knowledge base, which can facilitate subsequent protocol parsing of industrial devices using common protocols through the protocol parameter models.

[0075] In the embodiment of the present application, by executing step S110, it is possible to support converting the operation of configuring the protocol for each industrial device offline into automatic adaptation of the protocol remotely in the cloud, which helps to improve the operation and maintenance efficiency of the data acquisition platform.

[0076] S120. Connect the industrial device to the acquisition box.

[0077] In specific implementation, the acquisition box is managed by the data acquisition platform.

[0078] In specific implementation, after the industrial device is connected to the acquisition box, the data flow among the industrial device, the acquisition box, and the data acquisition platform can be as follows:

[0079] The data source of the data acquisition platform starts from the acquisition gateway. That is, the acquisition gateway pushes data to the EMQX cluster to which the data acquisition platform belongs through the Message Queuing Telemetry Transport (MQTT) protocol. The data acquisition platform receives the pushed data in real time and converges the pushed data in the time series database of the data acquisition platform in a continuous time series manner.

[0080] Among them, MQTT is a client-server based message publishing / subscribing transport protocol.

[0081] In the embodiment of the present application, by executing step S120, it is convenient to pull protocols from the protocol library of the data acquisition platform through the acquisition box, support converting the operation of configuring protocols for each industrial device offline into automatic protocol adaptation remotely in the cloud, which helps to improve the operation and maintenance efficiency of the data acquisition platform.

[0082] S130. Adopt the DLS algorithm, and pull protocols from the protocol library one by one through the acquisition box for protocol adaptation with industrial devices.

[0083] As an example, the operation process of protocol self-adaptation can be as Figure 3 shown: The acquisition box pulls protocols from the data acquisition platform one by one, and adapts and communicates with the industrial device with this protocol. If the communication fails, it pulls the next protocol and continues to perform adaptation communication until the adaptation is successful or all protocols are matched.

[0084] In one implementation manner, step S130 may include the following steps:

[0085] S131. Use the basic attributes of the protocol type as the restricted condition of the DLS algorithm, and set the number of data identifiers of the protocol as the search depth of the DLS algorithm.

[0086] The DLS algorithm is similar to the DFS algorithm with a predetermined limit. The DLS algorithm can solve the shortcoming of the infinite path in the DFS algorithm. In the DLS algorithm, nodes with a depth limit will be regarded as having no subsequent nodes.

[0087] In specific implementation, the number of the data identifiers can be set according to requirements and can be adjusted later as long as it does not exceed the number of data identifiers in the above protocol parameter model.

[0088] S132. Use this restricted condition to prune heterogeneous protocol types in the protocol library, and then use this search depth through the acquisition box to pull protocols from the protocol library one by one for effective judgment of data identifiers to perform protocol adaptation on industrial devices.

[0089] In specific implementation, the heterogeneous protocol type refers to a protocol type different from the protocol types adapted to industrial devices.

[0090] In practical applications, the DLS algorithm has two defects: one is that it is incomplete in itself and will not expand to search every node in all paths; the other is that if there are multiple valid solutions to a problem, it may not be able to find the optimal path.

[0091] However, specifically in the industrial scenario, these two disadvantages of the DLS algorithm can instead provide the computing consumption of the data acquisition platform and ensure the accuracy rate by controlling the search depth (L). Generally speaking, the data identifier of the serial port protocol is unique, and different combinations will generate different protocols. Therefore, when the search depth L is greater than 1 / 2 of the total length of the protocol, the accuracy rate of the protocol can be ensured. If special circumstances occur, the value of the search depth L can be appropriately increased to ensure the accuracy rate.

[0092] That is, in step S132, based on the DLS algorithm, it is possible to avoid getting into an infinite loop situation, reduce the platform computing consumption, and improve the memory efficiency.

[0093] In specific implementation, the implementation process of the above step S131 - step S132 can refer to Figure 4 as shown.

[0094] As an example, as Figure 5 shown, the protocols to be adapted are A, H, and J. Identify the basic attributes of the A protocol type. Among them, there are 5 targets with the same basic attributes of the protocol type. Set L = 2. When the search depth reaches L2, the node at this search depth is the last point, and it jumps to other paths to search. The search path is: B → C → F → H → I → J. At point J, a completely matching protocol is judged, and a message of successful adaptation is returned to the data acquisition platform to complete the adaptation activity. In this process, the efficiency is improved by:

[0095] [O(b*L m ) - O(b*L2)] / O(b*L m ) * 100% = 4 / 10 * 100% = 40%,

[0096] O(b*L) is the space complexity of the DLS algorithm, and L = 2.

[0097] That is, in the above step S131 - step S132, the node with the highest priority can be selected according to the priority specified in the priority queue as the current expansion node. When the expansion node reaches this depth, the search will be abandoned and other branches or nodes will be explored instead, thus solving the problem of infinite paths. Using the basic attributes of the protocol type as a restricted condition for preliminary protocol screening, and finally judging whether the corresponding protocol matches based on the valid range of the data identifier, the protocol self - adaptation operation can be completed.

[0098] In specific implementation, the above-mentioned valid judgment of the data identifier means that when the value of the data identifier of the protocol after radix conversion does not exceed the valid range, it is determined that the data identifier of the protocol is valid. Among them, the valid range can be set according to actual needs.

[0099] In the embodiment of the present application, by executing step S130, the DLS algorithm can be used to search and obtain the protocol matching the industrial device from the protocol library of the data acquisition platform with the least consumption, complete the protocol parsing of homogeneous and heterogeneous devices, reduce the operation of manual intervention configuration, thereby improving the usage efficiency of industrial software and reducing the implementation and operation and maintenance costs of the data acquisition platform.

[0100] In another implementation manner, as shown in combination with Figure 1 and Figure 4 the method for self-adapting the industrial device protocol in the embodiment of the present application may further include the following steps:

[0101] S130a. When traversing all the protocols in the protocol library and no target protocol matching the industrial device is found, a new protocol is entered into the protocol library and the new protocol is configured for the acquisition box.

[0102] In step S130a, the new protocol can be entered into the protocol library in the same or similar manner as step S111 above, and the embodiment of the present application will not elaborate here.

[0103] In specific implementation, after step S130a, step S130 can be returned for execution.

[0104] In the embodiment of the present application, by executing step S130a, it is possible to support updating the protocol library, further support converting the operation of configuring the protocol for each industrial device offline into automatic protocol adaptation remotely in the cloud, which helps to improve the operation and maintenance efficiency of the data acquisition platform.

[0105] S140. When a target protocol matching the industrial device is found, a successfully matched message is returned to the data acquisition platform through the acquisition box to end the protocol adaptation.

[0106] In specific implementation, when the values of the data identifiers of a certain protocol after radix conversion are all within the valid range, it can be determined that the protocol is the target protocol adapted to the industrial device. At this time, the protocol adaptation can be ended.

[0107] In specific implementation, when the industrial device protocol is successfully matched, a successfully matched message can be returned to the data acquisition platform through the acquisition box using the MQTT protocol. For example, the acquisition box uses the MQTT protocol to send an instruction of successful protocol matching to the data acquisition platform.

[0108] In the embodiment of the present application, by executing step S140, the data acquisition platform can be notified to store the protocol parsing data.

[0109] S150. The industrial device performs data parsing according to the target protocol, and then the acquisition box collects the protocol parsing data in real time.

[0110] In specific implementation, after the industrial device performs data parsing according to the target protocol, the acquisition box collects in real time the protocol parsing data obtained after the industrial device performs data parsing.

[0111] S160. The acquisition box transmits the protocol parsing data to the data acquisition platform, and the data acquisition platform stores the parsing data in the time series database.

[0112] In specific implementation, the acquisition box can transmit the protocol parsing data to the data acquisition platform by using the MQTT protocol. After receiving the protocol parsing data, the data acquisition platform can store the protocol parsing data in the time series database.

[0113] In summary, the present application can perform protocol self - adaptation for the application layer in the OSI model. Through the DLS algorithm, the protocol that matches is searched and obtained from the protocol library of the acquisition device with the least consumption, completing the protocol parsing of homogeneous and heterogeneous devices, reducing the operation of manual intervention configuration, thereby improving the use efficiency of industrial software and reducing the implementation and operation and maintenance costs of the data acquisition platform.

[0127] Use the restricted condition to prune the heterogeneous protocol types in the protocol library, and then use the search depth through the acquisition box to pull the protocols from the protocol library one by one for valid judgment of the data identifiers, so as to perform protocol adaptation on the industrial device.

[0128] In one implementation, the valid judgment of the data identifier means that when the value after the radix conversion of the data identifier of the protocol does not exceed the valid range, it is judged that the data identifier of the protocol is valid.
