[0028] The embodiments of the application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the application, and cannot be understood as limiting the application.

[0029] During the nuclear power production process, there are problems of parameter adjustment, equipment failure and equipment misoperation of the equipment, which will affect the normal progress of the nuclear power production, and therefore the maintenance personnel need to monitor at all times.

[0030] Currently, the operation and maintenance personnel on site view, low efficiency, and because the operation and maintenance personnel level is limited, for some difficult problems, the operation and maintenance personnel is difficult to quickly handle, thus affecting the normal operation of the device.

[0031] For the above problems, the embodiment of the application provides a remote collaboration interaction system for nuclear power production, which can realize intelligent and automatic monitoring of nuclear power production equipment, greatly improving the monitoring efficiency of the nuclear power production equipment. In addition, in the case of failure of the nuclear power production equipment, the remote terminal can send a repair order of the nuclear power production equipment and maintenance process data of the nuclear power production equipment to the remote terminal, so that the operation and maintenance personnel can learn about the failure of the nuclear power production equipment in time and repair the nuclear power production equipment according to the maintenance process data, reducing the repair difficulty of the operation and maintenance personnel and improving the repair efficiency of the nuclear power production equipment, thereby ensuring the efficient and safe operation of the nuclear power plant.

[0032] In addition, the remote terminal is used for sending a collaboration order to the expert terminal, and the expert terminal is used for updating the maintenance process data stored in the data interaction server. Especially when the operation and maintenance personnel face a failure that cannot be solved, the expert personnel can collaborate with the operation and maintenance personnel to repair the equipment and update the maintenance process data stored in the data interaction server in time, which helps to improve the success rate and efficiency of equipment repair and further ensures the efficient and safe operation of the nuclear power plant.

[0033] The remote collaboration interaction system for nuclear power production of the embodiment of the application will be described below with reference to the accompanying drawings.

[0034] Figure 1 A schematic diagram of a remote collaboration interaction system for nuclear power production provided by the embodiment of the application.

[0035] As shown in Figure 1 , the remote collaboration interaction system for nuclear power production comprises a device data acquisition terminal, a data interaction server, a remote terminal and an expert terminal.

[0036] The device data acquisition terminal is used for acquiring working state data of the nuclear power production equipment and sending the working state data to the data interaction server.

[0037] The data interaction server is used for detecting faults of the nuclear power production equipment based on the working state data and sending a repair order of the nuclear power production equipment and maintenance process data of the nuclear power production equipment to the remote terminal in the case of failure of the nuclear power production equipment.

[0038] The remote terminal is used for sending a collaboration order to the expert terminal.

[0039] The expert terminal is used for updating the maintenance process data stored in the data interaction server.

[0040] It should be noted that there must be at least one remote terminal and one expert terminal. For example, such as Figure 1 , 2 As shown, there are three remote terminals and three expert terminals. It should be noted that... Figure 1 , 2 The remote collaborative interaction system for nuclear power production shown is merely an example of the remote collaborative interaction system for nuclear power production in this application and should not be regarded as a limitation of the remote collaborative interaction system for nuclear power production in this application.

[0041] Remote terminals refer to the terminals used by operation and maintenance personnel (also called repair personnel or maintenance personnel). For example, the terminals used by operation and maintenance personnel for nuclear power production equipment that has malfunctioned may include mobile phones, computers, etc.

[0042] Expert terminals refer to the terminals used by expert personnel, such as those used by equipment manufacturers or professional maintenance personnel, and may include mobile phones, computers, etc.

[0043] In this application, the remote collaborative interaction system for nuclear power production can realize intelligent and automated monitoring of nuclear power production equipment, greatly improving the monitoring efficiency of nuclear power production equipment. In addition, in the event of a malfunction in nuclear power production equipment, it can send a repair order and maintenance process data of the nuclear power production equipment to a remote terminal, so that operation and maintenance personnel can promptly understand the malfunction of the nuclear power production equipment and repair the malfunctioning nuclear power production equipment according to the maintenance process data. This reduces the maintenance difficulty for operation and maintenance personnel, improves the maintenance efficiency of nuclear power production equipment, and ensures the efficient and safe operation of the nuclear power plant.

[0044] In addition, the remote terminal is used to send collaboration commands to the expert terminal, which in turn updates the maintenance process data stored on the data interaction server. This allows experts to collaborate with maintenance personnel to repair equipment when they encounter unsolvable faults and to update the maintenance process data stored on the data interaction server in a timely manner. This helps to improve the success rate and efficiency of equipment repair and further ensures the efficient and safe operation of the nuclear power plant.

[0045] Optionally, the expert terminal can also be used to send maintenance process data to remote terminals to assist maintenance personnel in performing equipment maintenance.

[0046] Optionally, the data interaction server is also used to send maintenance process data after the update of faulty nuclear power production equipment to remote terminals.

[0047] It should be noted that there are no excessive restrictions on nuclear power production equipment, which may include nuclear guidance equipment, steam turbines, generators, cooling equipment, water supply and drainage equipment, etc.

[0048] There are no strict limitations on the operating status data. For example, it can include the equipment's various operating parameters and output data under those parameters, as well as the equipment's output data under different operating states, such as the output data of a device under different voltage conditions or different flow rates. Equipment operating status includes the color of the equipment's operating lights, the on / off status of the equipment switches, and the on / off status of the equipment valves.

[0049] There are no strict limitations on the data for the maintenance process; for example, it may include maintenance steps.

[0050] There are no strict restrictions on the data interaction server; for example, it can include cloud servers, distributed servers, etc.

[0051] Optionally, such as Figure 2 As shown, the equipment data acquisition terminal includes a camera and an equipment parameter detection module. The camera is used to collect images of the nuclear power production equipment, and the equipment parameter detection module is used to collect the operating parameters and setting parameters of the nuclear power production equipment.

[0052] Optionally, the data interaction server is also used to retrieve reference status data of the nuclear power production equipment from the storage space, compare the reference status data with the operating status data, and determine whether the nuclear power production equipment has malfunctioned if the reference status data and the operating status data are inconsistent; or determine whether the nuclear power production equipment has malfunctioned if the reference status data and the operating status data are consistent. Thus, whether the locally stored reference status data is consistent with the actual operating status data can be considered to determine whether the nuclear power production equipment has malfunctioned.

[0053] It should be noted that reference status data refers to the status data of nuclear power production equipment under conditions where no malfunctions have occurred. For example, historical status data of nuclear power production equipment under malfunction conditions can be statistically analyzed to obtain reference status data. For details regarding reference status data, please refer to the relevant content on operational status data; these will not be elaborated upon here.

[0054] If the camera captures a device A where valve B is in the green "off" state, and after analysis and comparison, it is proven that valve B should normally be in the red "on" state, then a repair command is sent along with a reminder message indicating that valve B needs to be opened to the remote terminal.

[0055] Optionally, the data interaction server is also used to determine the fault information of nuclear power production equipment in the event of a fault, and to retrieve the corresponding maintenance process data from the storage space as the maintenance process data for the nuclear power production equipment. It is understood that there is a correspondence between the fault information and the maintenance process data; different fault information may correspond to different maintenance process data. The fault information is not subject to excessive limitations; for example, it may include fault type, fault cause, fault severity, etc.

[0056] Optionally, the expert terminal is also used to update the maintenance process data corresponding to the fault information stored on the data interaction server. Timely updating of the maintenance process data corresponding to the fault information stored on the data interaction server helps to improve the success rate and efficiency of equipment maintenance.

[0057] Optionally, the expert terminal is also used to access a data interaction server to obtain operational status data of the malfunctioning nuclear power production equipment, so that experts can understand the operational status data of the malfunctioning nuclear power production equipment.

[0058] Optionally, the expert terminal can also be used to send access requests to the data interaction server.

[0059] The data exchange server also determines whether an expert terminal has access rights to the data exchange server. If the expert terminal has such access rights, it processes the expert terminal's access request; otherwise, it rejects the expert terminal's access request. Therefore, the data exchange server can determine the expert terminal's access rights before processing the access request, preventing unauthorized personnel from accessing the data exchange server, thus improving data security and preventing data leakage.

[0060] Optionally, the data interaction server is further configured to extract the expert terminal's account information from the expert terminal's access request, retrieve reference account information from storage space, compare the reference account information with the expert terminal's account information, and determine whether the expert terminal has access to the data interaction server if the reference account information and the expert terminal's account information are inconsistent; conversely, determine whether the expert terminal has access to the data interaction server if the reference account information and the expert terminal's account information are consistent. Thus, the determination of whether the expert terminal has access can be based on whether the locally stored reference account information matches the actual expert terminal's account information.

[0061] Optionally, the remote terminal can also be used to visualize and / or broadcast repair commands and maintenance process data, simplifying user operations so that maintenance personnel can promptly understand repair commands and maintenance process data, thus optimizing the user experience.

[0062] For example, such as Figure 2 As shown, the data interaction server includes a wireless data transceiver module, a permission module, a storage module, a comparison module, an extraction module, and a command module. All of these modules are connected to the control module.

[0063] The wireless data transceiver module is used for data transmission and reception between the device data acquisition terminal, remote terminal, expert terminal and data interaction server, realizing remote data transmission and interaction.

[0064] To prevent unauthorized access to the data interaction server and improve security and confidentiality, the permission module is used to receive access permissions sent by the expert terminal. The permission module extracts the account information of the expert terminal and compares it with the account information stored in the storage module. If they match, the expert terminal is granted access permissions.

[0065] The storage module is used to store the device's various operating parameters and device output data under these parameters, device output data under different operating states, maintenance procedures corresponding to device fault information, and expert terminal account information.

[0066] The comparison module is used to compare the working status data sent by the device data acquisition terminal with the device output data under various operating parameters and device parameters in the storage module, as well as the device output data under different operating states. If they are inconsistent, the device fault information is obtained.

[0067] The storage module is a memory, which, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs. Furthermore, the memory may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. In some embodiments, the memory may optionally include memory remotely located relative to the control processor, and these remote memories can be connected to the remote collaborative equipment maintenance device via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0068] The extraction module is used to extract the corresponding equipment maintenance process from the storage module based on the equipment fault information.

[0069] The command module is used to send equipment maintenance procedures and repair commands to the remote terminal corresponding to the equipment.

[0070] Once the expert terminal gains access, it can view the equipment's operating status and working status. At the same time, the expert terminal can send the corresponding maintenance procedures for the equipment's operating status and working status to the storage module, thereby updating the database in the storage module, building a new comparison model, and reducing the losses caused by problems that nuclear power plant maintenance personnel cannot handle.

[0071] The collection, storage, use, processing, transmission, provision, and disclosure of user personal information involved in this application all comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0072] It should be noted that personal information collected from users should be used for legitimate and reasonable purposes and should not be shared or sold outside of these legitimate uses. Furthermore, such collection / sharing should only be conducted after receiving the user's informed consent, including but not limited to notifying the user to read the user agreement / user notice and sign an agreement / authorization that includes authorization of relevant user information before the user uses the function. In addition, any necessary steps must be taken to protect and safeguard access to such personal information data and ensure that others with access to personal information data comply with their privacy policies and procedures.

[0073] This application is intended to provide an implementation scheme for users to selectively prevent the use or access to their personal information data.
