[0002] The 3KeyMaster simulation platform is a platform that can perform full-range simulation of nuclear power plants, thermal power plants, etc. The 3KeyMaster simulation platform, interface cabinet (IO cabinet) and control cabinet usually exchange data through semi-physical communication. For example, the 3KeyMaster simulation platform and the interface cabinet (IO cabinet) usually communicate through ADS via the Beckhoff controller to achieve data transmission between the 3KeyMaster simulation platform and the IO cabinet.

[0025] The present invention discloses a gateway-based self-adaptive communication method, device, computer equipment and storage medium, which determines the corresponding interface cabinet from the communication mapping table through the data source of the first original data, so as to encapsulate the first original data into a standard format message adapted to the communication protocol of the interface cabinet through the protocol adapter corresponding to the interface cabinet, and send the standard format message to the interface cabinet through the communication channel corresponding to the interface cabinet, so that the interface cabinet parses the first original data from the standard format message and transmits the first original data to the control cabinet. It can be seen that in the present invention, the first original data is encapsulated into a standard format message adapted to the communication protocol of the interface cabinet through different protocol adapters, which can realize the communication between the nuclear power plant simulation platform and multiple interface cabinets supporting different communication protocols at the same time, avoiding the problem of relatively single communication mode supported in semi-physical communication. The following is an illustration through specific embodiments.

[0026] It should be understood that the nuclear power plant simulation platform and the interface cabinet in this embodiment communicate based on the communication gateway. The first original data that the nuclear power plant simulation platform needs to send to the control cabinet needs to be encapsulated into a standard format message that adapts to the communication protocol of the interface cabinet through the communication gateway, and then the standard format message is sent to the interface cabinet, so that the interface cabinet parses the first original data from the standard format message and transmits the first original data to the control cabinet. In addition, the communication gateway in this embodiment can be integrated into the nuclear power plant simulation platform, or it can be independent of the nuclear power plant simulation platform, but a data connection is established between it and the communication gateway.

[0027] based on Figure 1 In the specific implementation of , a flowchart of an implementation method of a gateway-based adaptive communication method is disclosed. The method is applicable to electronic devices with data processing and data transmission capabilities, such as mobile phones, computers, servers, etc. The method in this embodiment may specifically include the following steps: S101: Acquire the first original data that the nuclear power plant simulation platform needs to send to the control cabinet.

[0028] Specifically, in this embodiment, the first original data is obtained by reading the memory space of the nuclear power plant simulation platform. The nuclear power plant simulation platform in this embodiment includes but is not limited to the 3KeyMaster simulation platform, through which the full range of nuclear power plant scenarios, the full range of thermal power plant scenarios, etc. can be simulated.

[0029] Among them, whether it is a full-range nuclear power plant scenario simulated by the 3KeyMaster simulation platform or a real nuclear power plant, a nuclear power plant will generate a lot of first original data during operation. These first original data comprehensively reflect the operating status of the nuclear power plant, and these first original data need to be sent to the control system cabinet for the control cabinet to perform data storage or data processing. In addition, the nuclear power plant in this embodiment can be a nuclear power plant simulated by the simulation platform, or it can be a real nuclear power plant, which is not specifically limited in this embodiment. In addition, the control cabinet in this embodiment includes but is not limited to one or more of a turbine control cabinet (TCS) or a boiler control cabinet (DCS).

[0030] S102: According to the data source of the first original data, query a preset communication mapping table to determine a corresponding interface cabinet.

[0031] The data source of the first original data may represent the source address, data type or function type of the first original data, wherein the data source includes but is not limited to a nuclear island, a reactor or a steam turbine, etc., the data type includes but is not limited to temperature, humidity, pressure or water level, etc., and the function type refers to the data generated by different function modules in the simulation platform. In this embodiment, the specific basis for dividing the data source is not limited.

[0032] Specifically, in this embodiment, according to the data source of the first original data, the preset communication mapping table can be traversed and queried to determine the interface cabinet corresponding to the first original data in the communication mapping table. The communication mapping table at least includes the data source of the first original data and the channel identifier of the interface cabinet, and the corresponding communication channel is determined according to the channel identifier. The channel identifier can be the communication address corresponding to the interface cabinet, such as an IP address, and the channel identifier can also be manually set, such as TD1, TD2, etc. The specific form of the channel identifier is not limited in this embodiment.

[0033] S103: Loading a protocol adapter corresponding to the interface cabinet to encapsulate the first original data into a standard format message adapted to the communication protocol of the interface cabinet.

[0034] The protocol adapter is encapsulated based on the communication protocol encapsulation algorithm and the communication protocol parsing algorithm. It should be understood that each interface cabinet in this embodiment corresponds to a protocol adapter, or an interface cabinet supporting the same communication protocol corresponds to a protocol adapter.

[0035] Specifically, in this embodiment, the protocol adapter can be loaded through the protocol server. After the protocol adapter is loaded, the first original data is encapsulated into a standard format message of the adapter interface cabinet communication protocol through the protocol adapter.

[0036] S104: Sending the standard format message to the interface cabinet through the communication channel corresponding to the interface cabinet.

[0037] The communication channel is established based on the communication address and communication protocol supported by the interface cabinet.

[0038] Specifically, in this embodiment, a communication channel is established to establish a connection between the communication gateway and different interface cabinets. Different interface cabinets may support different communication protocols, and the communication protocol supported by the interface cabinet may be any one of TCP / IP, IPX / SPX or NetBEUI communication protocols.

[0039] For example, when the interface cabinet supports the TCP / IP communication protocol, the first original data can be encapsulated into a standard format message corresponding to the TCP / IP protocol through the communication channel corresponding to the interface cabinet, and then the standard format message can be sent to the interface cabinet through the communication channel. When the interface cabinet supports the IPX / SPX communication protocol, the first original data can be encapsulated into a standard format message corresponding to the IPX / SPX protocol through the communication channel corresponding to the interface cabinet, and then the standard format message can be sent to the interface cabinet through the communication channel.

[0040] When multiple first original data that need to be sent to the control cabinet by the nuclear power plant simulation platform are obtained at the same time, and the data sources of the first original data are different, the first original data from different data sources can be communicated in parallel based on corresponding different communication channels, which is conducive to improving the communication efficiency of semi-physical communication.

[0041] The interface cabinet and the control cabinet in this embodiment can be connected by hard wiring. Therefore, after sending the standard format message to the interface cabinet, the interface cabinet parses the first original data from the standard format message, and then transmits the first original data to the control cabinet through hard wiring. It should be noted that the first original data parsed by the interface cabinet is a digital signal. Therefore, when the interface cabinet transmits the first original data to the control cabinet through hard wiring, it is necessary to first convert the first original data into an electrical signal, and then transmit the electrical signal to the control cabinet through hard wiring. After receiving the electrical signal, the control cabinet restores the electrical signal to the first original data. In addition, the interface cabinet and the control cabinet in this embodiment can also transmit data wirelessly. The specific data transmission method between the interface cabinet and the control cabinet in this embodiment is not limited.

[0042] In summary, the present invention discloses a gateway-based self-adaptive communication method, which determines the corresponding interface cabinet from the communication mapping table through the data source of the first original data, so as to encapsulate the first original data into a standard format message adapted to the communication protocol of the interface cabinet through the protocol adapter corresponding to the interface cabinet, and send the standard format message to the interface cabinet through the communication channel corresponding to the interface cabinet, so that the interface cabinet parses the first original data from the standard format message and transmits the first original data to the control cabinet. It can be seen that in the present invention, the first original data is encapsulated into a standard format message adapted to the communication protocol of the interface cabinet through different protocol adapters, which can realize the communication between the nuclear power plant simulation platform and multiple interface cabinets supporting different communication protocols at the same time, avoiding the problem of relatively single communication mode supported in semi-physical communication.

[0043] based on Figure 1 In the specific implementation, the communication channel in this embodiment can be established in the following way: Figure 2 As shown: S201: Generate a cabinet configuration table based on the cabinet configuration operation performed by the user on the cabinet configuration interface.

[0044] S202: Load the cabinet configuration table to establish a communication channel between the nuclear power plant simulation platform and each interface cabinet based on the communication addresses and communication protocols corresponding to different interface cabinets.

[0045] The cabinet configuration table includes the communication address and communication protocol of the interface cabinet selected by the user. It can be understood that the interface cabinet selected by the user is the interface cabinet required by the user. For the interface cabinet that is not needed, the user may not select it, or choose to close the interface cabinet that is not needed. Of course, if the user needs to change the interface cabinet to be used, the user only needs to choose to open the corresponding interface cabinet on the cabinet configuration interface, or the user chooses to close the corresponding interface cabinet on the cabinet configuration interface.

[0046] In a specific implementation, the communication protocol and communication address of the interface cabinet selected by the user in this embodiment can be obtained by manually inputting the communication address and communication protocol, or selecting the corresponding communication address and communication protocol from the pre-prepared protocol list and communication address list. In this embodiment, there is no limitation on the method of obtaining the communication protocol and communication address corresponding to the interface cabinet. The communication addresses and communication protocols corresponding to different interface cabinets are loaded respectively, and a communication channel between the nuclear power plant simulation platform and each interface cabinet is established.

[0047] based on Figure 1 In the specific implementation, the communication channel in this embodiment can be established in the following way: Figure 3 As shown: S301: Acquire a communication protocol algorithm supported by each interface cabinet, where each communication protocol algorithm includes a communication protocol parsing algorithm and a communication protocol encapsulation algorithm.

[0048] The communication protocol encapsulation algorithm is used to encapsulate data into data messages, and the communication protocol parsing algorithm is used to parse data from the data messages.

[0049] S302: Based on each different communication protocol algorithm, encapsulate and obtain a protocol adapter corresponding to each interface cabinet.

[0050] The protocol adapter may be an application program with message encapsulation and message parsing capabilities. After being loaded by the protocol server, the protocol adapter may specify to parse the data message, or encapsulate the data into a data message.

[0051] In addition, different interface cabinets can support different communication protocols. Therefore, when the interface cabinet supports different communication protocols, protocol adapters that support different communication protocols can be obtained based on different communication protocol encapsulations, such as a protocol adapter that supports TCP / IP protocol, a protocol adapter that supports IPX / SPX protocol, etc.

[0052] It should be noted that in this embodiment, the corresponding protocol server can be loaded within a period of time before the nuclear power plant simulation platform and the control cabinet need to communicate, such as 1 second, 10 seconds before communication, so that when the first original data is obtained, the first original data is encapsulated through the protocol adapter to obtain standard format data. In this embodiment, the time for establishing the communication channel is not limited.

[0053] In summary, the modular design of the encapsulated protocol adapter in this embodiment is conducive to the use of a unified interface for different protocol adapters, and is conducive to operations such as establishing connections, reading and writing data, etc. In addition, the user can configure the interface cabinet through the cabinet configuration operation on the cabinet configuration interface, which simplifies the switching efficiency between the new and old interface cabinets and can achieve one-click switching of the interface cabinet.

[0054] based on Figure 1 In the specific implementation, the communication mapping table in this embodiment is obtained by the following method: Figure 4 As shown: S401: Obtain the communication addresses of all interface cabinets connected to the nuclear power plant simulation platform, and the data sources of different types of first original data in the nuclear power plant simulation platform.

[0055] S402: Generate a communication mapping table according to the communication address and data source.

[0056] It should be understood that the first original data from different data sources in the nuclear power plant simulation platform may need to be stored in different cabinets in the control cabinet after being sent to the control cabinet, and the interface cabinets connected to different cabinets may be different. Therefore, in order to accurately send the first original data from different data sources of the nuclear power plant simulation platform to different cabinets for storage, it is necessary to establish the data sources of different types of first original data of the nuclear power plant simulation platform, and the communication addresses of all interface cabinets connected to the nuclear power plant simulation platform, and then generate a communication mapping table based on the communication address and data source. Among them, the data source of the first original data in the communication mapping table corresponds one-to-one to the communication address of the interface cabinet.

[0057] In the specific implementation, in this embodiment, the communication addresses of all interface cabinets that have established connections with the nuclear power plant simulation platform and the data sources of different types of first original data in the nuclear power plant simulation platform can be obtained by scanning the memory space of the nuclear power plant simulation platform, and then a communication mapping table can be generated according to the communication addresses and data sources.

[0058] To sum up, by establishing a communication mapping table, this embodiment can quickly determine the communication channel to be used according to the correspondence between the data source of the first original data and the communication address of the interface cabinet, and then send the standard format message converted from the first original data to the interface cabinet through the communication channel, and then transmit the standard format message to the control cabinet through the interface cabinet.

[0059] In one implementation, the method in this embodiment further includes the following steps: Figure 5 As shown: S501: Obtain communication quality parameters of a communication channel in real time by subscription.

[0060] The quality parameters of the communication channel include, but are not limited to, delay parameters and packet loss rate of the communication channel for message format conversion and feedback after message sending.

[0061] S502: Determine whether the communication channel is in an abnormal state according to the communication quality parameter.

[0062] The communication quality parameter is compared with a preset parameter threshold. If the communication quality parameter is greater than the parameter threshold, it is determined that the communication channel is in an abnormal state; if the communication quality parameter is less than or equal to the parameter threshold, it is determined that the communication channel is in a normal state.

[0063] For example, taking the communication quality parameter as the delay parameter as an example, assuming that the delay parameter threshold is 10 seconds, when the delay parameter is greater than 10 seconds, such as when the delay parameter is 22 seconds, or when the delay parameter approaches infinity, it is determined that the communication channel is in an abnormal state; when the delay parameter is less than 10 seconds, such as when the delay parameter is 0.5 seconds, it is determined that the communication channel is in a normal state.

[0064] S503: If the communication channel is in an abnormal state, the communication quality parameter is recorded in a communication abnormality log, and the communication abnormality log is pushed to the user.

[0065] If the communication channel is in an abnormal state, the communication quality parameters are recorded in the communication abnormality log, and the communication abnormality log is pushed to the user; if the communication channel is in a normal state, the communication quality parameters of the communication channel are continuously obtained to continuously monitor the communication quality of the communication channel.

[0066] Specifically, in this embodiment, interfaces such as user management and device management can be provided at the business layer in the communication gateway, thereby realizing functions such as log management and status monitoring. Through the status monitoring function, the communication quality of the communication channel can be continuously monitored, and through the log management function, the communication quality parameters can be recorded in the communication anomaly log, and then the communication anomaly log recording the communication quality parameters can be sent to the user's mobile device, such as a mobile phone.

[0067] To sum up, in this embodiment, the communication status of the communication channel is monitored in real time, and when the communication status of the communication channel is abnormal, the data related to the communication channel status is recorded in the communication abnormality log, and the communication abnormality log is pushed to the user, so that the user can take timely response measures to ensure the communication efficiency of the communication channel.

[0068] In one implementation, the nuclear power plant simulation platform can send data to the control cabinet, and the control cabinet can also send data to the nuclear power plant simulation platform, that is, data can be exchanged between the control cabinet and the nuclear power plant simulation platform. The control cabinet sends data to the nuclear power plant simulation platform, which can be implemented through the following steps: Figure 6 As shown: S601: Acquire a target format message sent by an interface cabinet through a corresponding communication channel.

[0069] The target format message is obtained by encapsulating the second original data transmitted from the control cabinet to the interface cabinet. The control cabinet and the interface cabinet are connected by hard wiring. Therefore, the control cabinet needs to convert the second original data from a digital signal to an electrical signal, and then transmit it to the interface cabinet through hard wiring. The interface cabinet then converts the electrical signal to a digital signal to obtain the second original data transmitted from the control cabinet to the interface cabinet.

[0070] It should be understood that there may be an association relationship between the first original data and the second original data, or there may be no association relationship between the first original data and the second original data.

[0071] When the first original data and the second original data may be associated, the second original data transmitted by the control cabinet to the interface cabinet may be the second original data generated by the control cabinet after the control cabinet analyzes and processes the first original data after receiving the first original data. The control cabinet returns the second original data to the interface cabinet, and the interface cabinet encapsulates the second original data into a target format message. After the interface cabinet sends the target format message to the communication gateway, the nuclear power plant simulation platform can obtain the target format message sent by the interface cabinet through the corresponding communication channel.

[0072] Specifically, the control cabinet in this embodiment can send the second original data to the communication gateway through the corresponding interface cabinet to obtain the second original data that the control cabinet needs to send to the nuclear power plant simulation platform.

[0073] S602: Loading a protocol adapter corresponding to the interface cabinet to parse the target format message to obtain second original data.

[0074] The protocol adapter is encapsulated based on the communication protocol encapsulation algorithm and the communication protocol parsing algorithm. It should be understood that each interface cabinet in this embodiment corresponds to a protocol adapter, or an interface cabinet supporting the same communication protocol corresponds to a protocol adapter.

[0075] Specifically, in this embodiment, the protocol adapter can be loaded through the protocol server. After the protocol adapter is loaded, the first original data is encapsulated into a standard format message of the adapter interface cabinet communication protocol through the protocol adapter.

[0076] S603: Convert the format of the second original data through the gateway converter to obtain unified format data commonly used within the nuclear power plant simulation platform.

[0077] The gateway converter can enable an application with data format conversion, for example, the unified digital format commonly used in the power plant simulation platform is to retain two decimal places, then the number 80 is converted to 80.00 after format conversion, and the number 80.1765 is converted to 80.18 after format conversion. Based on this, the second original data can be converted into a unified format data commonly used in the nuclear power plant simulation platform.

[0078] S504: Sending the unified format data to the nuclear power plant simulation platform through the protocol interface of the nuclear power plant simulation platform.

[0079] Specifically, the communication gateway in this embodiment can communicate with the nuclear power plant simulation platform through a unified protocol interface to transmit data between the communication gateway and the nuclear power plant simulation platform. After the unified format data is sent to the nuclear power plant simulation platform through the protocol interface, the nuclear power plant simulation platform can directly use the unified format data, or, after a simple format conversion, the nuclear power plant simulation platform can directly use it.

[0080] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0081] like Figure 7 As shown, a gateway-based adaptive communication device disclosed in an embodiment of the present invention is applicable to electronic devices with data processing and data transmission capabilities, such as mobile phones, computers, servers, etc. The device in this embodiment may specifically include the following units: The first original data acquisition unit 701 is used to acquire the first original data that the nuclear power plant simulation platform needs to send to the control cabinet; The interface cabinet determining unit 702 is used to query a preset communication mapping table according to the data source of the first original data to determine the corresponding interface cabinet; The message encapsulation unit 703 is used to encapsulate the first original data into a standard format message adapted to the communication protocol of the interface cabinet through the protocol adapter corresponding to the interface cabinet; the protocol adapter encapsulates the message based on the communication protocol encapsulation algorithm and the communication protocol parsing algorithm; The message sending unit 704 is used to send the standard format message to the interface cabinet through the communication channel corresponding to the interface cabinet; the communication channel is established based on the communication address and communication protocol supported by the interface cabinet; After receiving the standard format message, the interface cabinet parses the standard format message to obtain the first original data, and transmits the first original data to the control cabinet.
