[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0021] The following describes the safety monitoring system of a thermal power plant in an embodiment of the present application with reference to the accompanying drawings.

[0022] Figure 1 It is a structural diagram of a safety monitoring system for a thermal power plant according to an embodiment of the present application.

[0023] like Figure 1 As shown, the safety monitoring system of the thermal power plant includes a monitoring perception layer 101, an intelligent analysis layer 102 and a research and decision-making layer 103, wherein:

[0024] In some embodiments, Figure 1 As shown, the monitoring perception layer 101 communicates with the intelligent analysis layer 102 through the network to obtain all safety-related data of the thermal power plant and send the safety-related data to the intelligent analysis layer 102.

[0025] Among them, the monitoring perception layer 101 can communicate with the intelligent analysis layer 102 through a wired network or a wireless network. For example, the monitoring perception layer 101 can communicate with the intelligent analysis layer 102 through a 4G network, a 5G network, Wireless Fidelity (Wireless Fidelity, Wi-Fi), Bluetooth, and a communication line, but is not limited to this.

[0026] In some embodiments, the intelligent analysis layer 102 is used to receive and store security-related data, and perform security screening on the security-related data based on security thresholds corresponding to the security-related data.

[0027] In some embodiments, the intelligent analysis layer 102 may receive and store relevant security data through a memory and a network data receiving device, but is not limited thereto.

[0028] In other embodiments, historical security-related data can be trained through machine learning to obtain the changing trend of the security threshold corresponding to the historical security-related data, so as to determine the final security threshold from the changing trend, and then screen the security-related data according to the security threshold to obtain abnormal security-related data that does not meet the security threshold, thereby realizing intelligent identification of security-related data and improving the data analysis efficiency of security-related data.

[0029] In some embodiments, the analysis and decision-making layer 103 communicates with the intelligent analysis layer 102 through the network to obtain safety screening results based on the received safety-related data, generate monitoring instructions corresponding to the safety screening results, and regulate the thermal power plant based on the monitoring instructions.

[0030] In some embodiments, when there is no abnormal safety-related data in the safety screening results, the generated monitoring instructions may include but are not limited to normal status without adjustment. Under this safety screening result, all equipment in the thermal power plant operates normally and safely.

[0031] In other embodiments, when there are one or more abnormal safety-related data in the safety screening results, the thermal power plant equipment corresponding to the abnormal safety-related data is found, and the abnormal state is judged based on the abnormal related safety data to generate a monitoring instruction to adjust the abnormal state to a normal state, thereby adjusting the equipment of the thermal power plant to a normal and safe state, thereby realizing intelligent dynamic regulation of the thermal power plant.

[0032] In some embodiments, Figure 1 As shown, the safety-related data includes environmental safety data, scene safety data and operation safety data of the thermal power plant, and the monitoring perception layer 101 includes an environmental status monitoring module 1011, a scene monitoring module 1012 and an equipment operation data monitoring module 1013, including:

[0033] In some embodiments, the environmental status monitoring module 1011 is used to obtain environmental safety data of the thermal power plant.

[0034] The environmental safety data may include, but is not limited to, environmental temperature and environmental sound, which are not specifically limited in this embodiment.

[0035] The environmental safety data may be monitoring values ​​acquired by sensors in the environmental status monitoring module 1011, but is not limited thereto.

[0036] Specifically, taking a fire gas leak in a thermal power plant as an example, environmental safety data may include smoke, ambient temperature, and toxic gas concentration, but is not limited thereto. Smoke, ambient temperature, and toxic gas concentration may also be transmitted to the intelligent analysis layer 102 for storage to facilitate later retrieval by management personnel.

[0037] In some embodiments, the scene monitoring module 1012 is used to obtain scene safety data of the thermal power plant.

[0038] Among them, the scene safety data may include but is not limited to the locations of personnel in the monitoring video of the thermal power plant and the thermal power plant scene, which is not specifically limited in this embodiment.

[0039] The scene safety data may be video data collected by a camera in the scene monitoring module 1012, but is not limited thereto.

[0040] Specifically, a camera system is installed in the thermal power plant, high-definition cameras are installed in key safety areas, and video images are transmitted to the intelligent analysis layer 102 through the plant Wi-Fi system and saved for viewing and analysis by plant personnel. In addition, plant staff can obtain real-time locations by carrying portable positioning devices and upload them to the intelligent analysis layer 102 to achieve accurate positioning of scene safety data in key safety areas and improve the processing efficiency of scene safety data.

[0041] In some embodiments, the equipment operation data monitoring module 1013 is used to obtain the operation safety data of the equipment of the thermal power plant.

[0042] The operational safety data of the equipment of the thermal power plant may include, but is not limited to, the operational pressure and operational flow rate of the equipment of the thermal power plant, which are not specifically limited in this embodiment.

[0043] Among them, the operation safety data can be the value collected by the sensor in the equipment operation data monitoring module 1013. For example, the flow of the thermal power plant equipment can be collected through a flow sensor, and the pressure of the thermal power plant equipment can be collected through a pressure sensor, but it is not limited to this.

[0044] Specifically, taking all the data generated during the operation of a thermal power plant as an example, since all the data generated cover a large amount of equipment operation data, the equipment operation data monitoring module 1013 can only select the operation safety data related to the safe operation of the equipment of the thermal power plant, thereby reducing the operation data of the thermal power plant and improving the processing efficiency of the thermal power plant safety monitoring and management system.

[0045] In some embodiments, Figure 1 As shown, the intelligent analysis layer 102 includes a data platform 1021 and an analysis module 1022, wherein:

[0046] The data platform 1021 communicates with the monitoring perception layer 101 through the network, receives and stores security-related data, and transmits the security-related data to the analysis module 1022 .

[0047] The data platform 1021 may be composed of a memory and a wireless network data transceiver, but is not limited thereto.

[0048] Specifically, the wireless network data receiving and sending device can be used to receive and send security-related data, and the security-related data can be stored in a memory to facilitate later calls.

[0049] The analysis module 1022 communicates with the data platform 1021 module through the network and is used to screen the security-related data based on the security thresholds corresponding to the security-related data.

[0050] In some embodiments, security-related data can be divided into normal security-related data and abnormal security-related data by security thresholds. Then, only abnormal security-related data needs to be processed, and normal security-related data does not need to be processed, thereby reducing the amount of security-related data and speeding up the processing.

[0051] In some embodiments, Figure 1 As shown, the intelligent analysis layer 102 also includes a machine learning module 1023, wherein:

[0052] The machine learning module 1023 communicates with the analysis module 1022 via a network and is used to perform security threshold training on historical security-related data to obtain security thresholds corresponding to the security-related data.

[0053] In some embodiments, the machine learning module 1023 obtains corresponding security thresholds for different security-related data through different machine learning algorithms, and sends the security thresholds to the analysis module 1022 through the network, so as to obtain security screening results corresponding to the security-related data and realize intelligent management of security-related data.

[0054] In some embodiments, Figure 1 As shown, the analysis and decision-making layer 103 includes a manual analysis module 1031, an inspection module 1032 and an execution module 1033, wherein:

[0055] The manual analysis module 1031 communicates with the analysis module through the network, is used to receive the security screening results of the analysis module, and manually verify the correctness of the security screening results.

[0056] In some embodiments, the security screening results can be verified by professional technicians to remove security screening results with large errors to ensure the correctness of all security screening results.

[0057] The inspection module 1032 communicates with the analysis module through the network and is used to inspect the equipment of the thermal power plant corresponding to the safety screening result.

[0058] In some embodiments, the inspection may be performed manually or by an intelligent robot, and this embodiment does not specifically limit this.

[0059] Specifically, on the one hand, manual inspections can be used for areas in thermal power plants that are not dangerous. On the other hand, robot inspections can be used for areas that may be dangerous or where it is difficult for manual labor to carry out operations. Fault diagnosis and troubleshooting can also be carried out. Thus, in terms of inspections, a combination of robot and manual inspections can be adopted according to dangerous areas and non-dangerous areas, thereby improving the safety of inspections and avoiding safety accidents that may be caused by inspections of dangerous points or areas where it is difficult for manual labor to carry out operations.

[0060] The execution module 1033 communicates with the analysis module through the network to generate monitoring instructions corresponding to the safety screening results and regulate the thermal power plant based on the monitoring instructions.

[0061] In some embodiments, the thermal power plant can be regulated by monitoring instructions, while abnormal conditions can be published through the thermal power plant's broadcasting system, and the monitoring instructions can be sent to the client to facilitate relevant technical personnel to comprehensively view and process in real time to ensure the safety of the thermal power plant.

[0062] The present application proposes a safety monitoring system for a thermal power plant, which includes a monitoring perception layer, an intelligent analysis layer and a research and judgment decision layer, wherein the monitoring perception layer communicates with the intelligent analysis layer through a network, and is used to obtain all safety-related data of the thermal power plant, and send the safety-related data to the intelligent analysis layer, the intelligent analysis layer is used to receive and store the safety-related data, and perform safety screening on the safety-related data based on the safety threshold corresponding to the safety-related data, the research and judgment decision layer communicates with the intelligent analysis layer through a network, and is used to perform safety screening results based on the received safety-related data, and generate monitoring instructions corresponding to the safety screening results, so as to control the thermal power plant. Thus, based on the safety screening of all safety-related data of the thermal power plant, the thermal power plant is controlled according to the monitoring instructions corresponding to the safety screening results, so as to realize all-round monitoring of the thermal power plant and improve the accuracy of safety monitoring of the thermal power plant.

[0063] On the other hand, the present application proposes a safety monitoring method for a thermal power plant, such as Figure 2 As shown, Figure 2 It is a flow chart of a safety monitoring method for a thermal power plant according to an embodiment of the present application.

[0064] Step 201, obtaining all safety-related data of the thermal power plant.

[0065] In some embodiments, an implementation method for obtaining all safety-related data of a thermal power plant is to obtain the environmental safety data of the thermal power plant, the scene safety data of the thermal power plant, and the operational safety data of the thermal power plant equipment, and use the environmental safety data, scene safety data, and operational safety data as safety-related data, thereby achieving all-round monitoring of the safety-related data of the thermal power plant and improving the accuracy of safety monitoring of the thermal power plant.

[0066] Step 202: Perform security screening on the security-related data to obtain security screening results of the security-related data.

[0067] In some embodiments, security screening is performed on security-related data to obtain a security screening result of the security-related data. One implementation method is to obtain a security threshold corresponding to the security-related data, screen the security-related data based on the security threshold, and use security-related data greater than the security threshold as the security screening result, thereby achieving accurate screening of security-related data and realizing intelligent processing of security-related data.

[0068] Specifically, historical safety-related data of the thermal power plant can be obtained, and the historical safety-related data can be trained and processed through a machine learning algorithm to obtain the corresponding safety thresholds under the safe operation of the thermal power plant.

[0069] Among them, video data, personnel location data, environmental sound settings and operation monitoring data can be used as historical relevant safety data respectively. The above historical relevant safety data have been trained and processed through different machine learning algorithms to obtain the corresponding safety thresholds under the safe operation of the thermal power plant, and at the same time, the abnormal situations corresponding to the historical relevant safety data are displayed, as shown in Table 1.

[0071]

[0072] Step 203: Generate monitoring instructions corresponding to the safety screening results according to the safety screening results, and regulate the thermal power plant based on the monitoring instructions.

[0073] In some embodiments, monitoring instructions corresponding to the safety screening results are generated based on the safety screening results, and an implementation method for regulating the thermal power plant based on the monitoring instructions may be to obtain initial safety screening results, verify the correctness of the initial safety screening results to obtain correct safety screening results, obtain inspection results of the equipment in the thermal power plant, and when the inspection results match the safety screening results, generate monitoring instructions corresponding to the safety screening results, and regulate the thermal power plant based on the monitoring instructions.
