BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0054] As described above, the current method of troubleshooting is to copy and analyze the on-site logs, records and other information of the full-range simulator. Taking the on-site log as an example, the problem is located and reproduced by copying and analyzing the on-site log of the full-range simulator. Since the number of on-site logs of the full-range simulator is huge, and the on-site logs of the full-range simulator are for each individual module that constitutes the full-range simulator, it takes a long time to locate and fully reproduce the problem, resulting in a long time for troubleshooting, which makes the efficiency of problem solving low. Furthermore, since the on-site logs of the full-range simulator are for each individual module, it involves the correlation problems between the modules generated under complex working conditions. It is difficult to reproduce the correlation problems between the modules by analyzing the on-site logs, which leads to the failure of locating and reproducing the problem, and the problem cannot be found, which leads to the failure of problem solving.

[0055] The current technology also has a method of replaying data through storage backtracking. This method can reproduce the phenomenon after the problem occurs to a large extent. For example, an operator clicks a switch button, which causes a problem in the simulated DCS system. However, this method cannot locate and reproduce the problem, so it cannot troubleshoot and solve the problem.

[0056] In summary, the present application provides a data recording and playback method for a simulator, the method comprising: in response to a start recording command, acquiring communication data packets in the simulator at a preset period; storing the acquired communication data packets, the communication data packets being defined with corresponding unique identifiers in chronological order; in response to a stop recording command, stopping the acquisition and storage of the communication data packets; replaying the communication data packets based on the stored communication data packets; and displaying the unique identifier of the communication data packet currently being replayed based on the communication data packet currently being replayed. The method records, stores and replays the interactive data in the simulator, and can reproduce the interactive process of the full range of simulators, and can still fully reproduce the module correlation problems at the system level, that is, achieve complete reproduction of the phenomenon / problem; and based on the unique identifier of the communication data packet, the problem can be quickly located, thereby greatly reducing the time required for troubleshooting the problem, thereby improving the efficiency of problem solving.

[0057] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described 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 creative work are within the scope of protection of this application.

[0058] Example 1

[0059] Combine the following Figure 1-Figure 3 A data recording and playback method for a simulator provided in an embodiment of the present application is introduced in detail.

[0060] First combine Figure 1 The composition structure of the full-scale simulator is described as follows: The full-scale simulator includes a model server 101 , a model gateway 102 and a virtual DCS server 103 .

[0061] The model server 101 mainly runs the nuclear power plant process system model, and is connected to the virtual DCS server 103 through the model gateway 102 , and the model server 101 communicates and transmits data with the virtual DCS server through the model gateway 102 .

[0062] The process system model of a nuclear power plant mainly includes: nuclear reactor model. A nuclear reactor, also known as an atomic reactor or reactor, is a device that can maintain a controllable self-sustaining chain nuclear fission reaction to achieve nuclear energy utilization. The nuclear reactor is the core device of a nuclear power plant. The nuclear reactor is based on the fission of atomic nuclei to achieve nuclear power generation.

[0063] The model gateway 102 is mainly used to transmit communication data between the model server 101 and the virtual DCS server.

[0064] The virtual DCS server 103 is obtained by simulating the actual DCS through software. The use of the virtual DCS server 103 can effectively improve the realism of the full-range simulator.

[0065] Distributed Control System (DCS) is an instrument control system based on microprocessors, which adopts the design principles of decentralized control functions, centralized display operations, and taking into account the design principles of decentralized autonomy and comprehensive coordination. It adopts the basic design concept of decentralized control and centralized operation and management, and adopts a multi-level hierarchical, cooperative and autonomous structure. Its main features are its centralized management and decentralized control, so it is widely used in nuclear power, metallurgy, petrochemical and other industries.

[0066] Combine the following Figure 2 , a data recording and playback method for a simulator provided in an embodiment of the present application is introduced in detail.

[0067] S210, the recording and playback device responds to the start recording command to obtain the communication data packets in the simulator at a preset period.

[0068] The start recording command is a command for starting communication data recording.

[0069] Specifically, the start recording command may be to turn on the "recording" switch of the model gateway in the full-range simulator through software control / user operation during the operation of the full-range simulator.

[0070] Specifically, the communication data packets between the model server 101 and the virtual DCS server 103 (the communication data packets transmitted in the model gateway 102) are obtained at a preset period.

[0071] Specifically, the communication data between the model server 101 and the virtual DCS server 103 is obtained at a preset period, the communication data within a preset period is packaged into a communication data packet, and the communication data packets in the full range simulator are obtained at a preset period.

[0072] S220: The recording and playback device stores the acquired communication data packet, where the communication data packet carries a corresponding unique identifier.

[0073] Specifically, the acquired communication data packets may be stored in a cloud server or a specific database.

[0074] Specifically, the corresponding unique identifier carried by the communication data packet is assigned to the acquired communication data packets in chronological order to distinguish each communication data packet. In this way, when replaying the communication data packet, the unique identifier of the communication data packet can be used to replay the specified time interval and quickly locate the problem.

[0075] S230: The recording and playback device stops acquiring and storing communication data packets in response to the stop recording command.

[0076] The stop recording command is a command used to stop recording communication data.

[0077] Specifically, the stop recording command may be to turn off the "recording" switch of the model gateway in the full-range simulator through software control / user operation during the operation of the full-range simulator.

[0078] S240: The recording and playback device plays back the stored communication data packets in response to the playback command.

[0079] Specifically, the recording and playback device obtains the communication data packet from the cloud server or a specific database storing the communication data packet, parses the obtained communication data packet, obtains the corresponding communication data, and runs the corresponding communication data to realize the playback of the stored communication data packet. The playback of the stored communication data packet realizes the playback of the data interaction in the full-range simulator, that is, the data interaction between the model server 101 and the virtual DCS server 103 corresponding to the communication data packet (data transmission in the model gateway 102). Because it is the interactive data in the full-range simulator that is played back, the correlation problem between the modules can be fully reproduced, so the phenomenon corresponding to the full-range simulator can be quickly reproduced by playing back the communication data packet. Since each communication data packet has a corresponding unique identifier, the unique identifier can indicate the time when the phenomenon / problem corresponding to the corresponding communication data packet is performed, thereby realizing the rapid location and reproduction of the problem, reducing the time for troubleshooting, and thus improving the speed of problem solving.

[0080] S250: The recording and playback device displays a unique identifier of the communication data packet currently being played back based on the communication data packet currently being played back.

[0081] Specifically, the recording and playback device can display the unique identifier of the communication data packet currently being played back in real time, so that on-site operators, trainers, etc. can intuitively obtain the communication data packet currently being played back, so that on-site operators, trainers, etc. can quickly locate the problem based on the unique identifier of the communication data packet currently being played back.

[0082] For ease of understanding, the following Figure 3 A schematic diagram of a playback interface provided by an embodiment of the present application is shown, and a method for replaying a communication data packet provided by an embodiment of the present application is introduced in detail.

[0083] Specifically, the recording and playback device pre-sets the starting communication data packet, that is, sets the unique identifier corresponding to the starting communication data packet, and plays back the stored communication data packets starting from the starting communication data packet based on the time sequence (or the sequence of the unique identifiers of the communication data packets).

[0084] Specifically, through user operation, in the setting box 302 corresponding to the starting communication data packet corresponding to the starting setting 301 of the playback interface, the unique identifier corresponding to the starting communication data packet is filled in, and playback can be started from the starting communication data packet.

[0085] Replay data starting from the starting communication data packet. For example, based on the phenomenon of the full-range simulator, on-site operators or trainers can determine the approximate time when a problem may occur. The communication data packet 200 cycles (wherein the preset cycle is 100 milliseconds) before that time can be set as the starting communication data packet. Replaying data starting from the starting communication data packet can locate the time when the problem occurred and reproduce the problem that occurred at that time, while greatly reducing the number of communication data packets replayed, thereby reducing the time for troubleshooting the problem and further improving the efficiency of problem solving.

[0086] Furthermore, the recording and playback device plays back the communication data packets, and can select a playback mode, which includes: one-by-one playback and continuous playback.

[0087] Specifically, the one-by-one playback is to individually play back the stored communication data packets period by period in response to the one-by-one playback operation.

[0088] For ease of understanding, the following description takes the setting of the initial communication data packet as an example.

[0089] One-by-one playback is based on the one-by-one playback operation, and a single data packet is played back from the initial communication data packet. For example: the communication data packet uniquely identified as N is set as the initial communication data packet. When the user clicks the icon of one-by-one playback 303 on the playback interface, the communication data packet uniquely identified as N is played back. When the user clicks the icon of one-by-one playback 303 on the playback interface again, the communication data packet uniquely identified as N+1 is played back (i.e., the next communication data packet in the time sequence of the communication data packet uniquely identified as N is played back). The one-by-one playback method is adopted to realize the playback of each communication data packet one by one. The communication data packets around the time when the problem occurs can be played back one by one. The phenomenon reproduced by the playback of the communication data packets can be analyzed in detail, which improves the accuracy of problem troubleshooting.

[0090] Specifically, the continuous playback is to continuously play back the stored communication data packets in response to the continuous playback operation until the playback ends.

[0091] For ease of understanding, the following description takes the setting of the initial communication data packet as an example.

[0092] Continuous playback is based on continuous playback operations, and continuous playback is performed from the initial communication data packet. For example: set the communication data packet uniquely identified as N as the initial communication data packet. When the user clicks the icon of continuous playback 304 on the playback interface, the communication data packet uniquely identified as N is played back. When the playback of communication data packet N is completed, the communication data packet uniquely identified as N+1 is automatically played back without the need for user operation again. The continuous playback method is adopted to achieve continuous playback of communication data packets, and the phenomena occurring in the full-range simulator are reproduced more coherently. Correlation problems can be analyzed based on continuous phenomena, which further improves the fidelity of reproduction of correlation problems at the system level, thereby reducing the time for troubleshooting problems.

[0093] Furthermore, the initial state can be restored, that is, the position of the initial communication data packet can be restored, and the playback mode can be re-selected to play back the communication data packet. Repeated playback of the communication data packet can more accurately identify the problem, thereby improving the efficiency of problem solving.

[0094] Furthermore, the recording and playback device can pre-set the end communication data packet, that is, set the unique identifier corresponding to the end communication data packet, and replay the stored communication data packets starting from the starting data packet (the first communication data packet) based on the time sequence (or the order of the unique identifiers of the communication data packets). When the playback of the end communication data packet is completed, the playback of the stored communication data packet is directly ended.

[0095] Specifically, through user operation, in the setting box 306 corresponding to the end communication data packet corresponding to the end setting 305 of the playback interface, the unique identifier corresponding to the end communication data packet is filled in, so that the playback can be automatically ended after the playback of the end communication data packet is completed. According to the approximate time of the problem occurrence provided by the on-site operator, training personnel, etc., the starting communication data packet and the end communication data packet are set, which can greatly reduce the number of communication data packets played back, further reduce the time required for troubleshooting, and thus improve the efficiency of problem solving.

[0096] Furthermore, the unique identifier of the communication data packet currently being played back is displayed. Specifically, in the playback interface, in the display box of the unique identifier of the currently played back communication data packet 308 corresponding to the current playback 307 on the playback interface, the unique identifier of the currently played back communication data packet can be displayed in real time, so that on-site operators, trainers, etc. can intuitively obtain the currently played back communication data packet, so that on-site operators, trainers, etc. can quickly locate the problem based on the unique identifier of the currently played back communication data packet.

[0097] In summary, the embodiment of the present application provides a data recording and playback method for a simulator, the method comprising: in response to a start recording command, acquiring communication data packets in the simulator at a preset period; storing the acquired communication data packets, the communication data packets being defined with corresponding unique identifiers in chronological order; in response to a stop recording command, stopping the acquisition and storage of the communication data packets; replaying the communication data packets based on the stored communication data packets; and displaying the unique identifier of the communication data packet currently being replayed based on the communication data packet currently being replayed. The method records, stores and replays the interactive data in the simulator, which can reproduce the interactive process of the simulator, and can still fully reproduce the module correlation problems at the system level, that is, achieve complete reproduction of the phenomenon / problem; and can display the unique identifier of the communication data packet currently being replayed, and can realize rapid location of the problem based on the unique identifier of the communication data packet, thereby greatly reducing the time required for troubleshooting the problem, and thus improving the efficiency of problem solving.

[0098] Furthermore, the unique identifier of the communication data packet currently being played back can be displayed in real time, so that on-site operators, trainers, etc. can intuitively obtain the communication data packet currently being played back, so that on-site operators, trainers, etc. can quickly locate the problem based on the unique identifier of the communication data packet currently being played back.
