[0027] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] A thermal power plant intelligent inspection system, such as Figure 1 and Figure 2As shown, the device includes a movable inspection device and a monitoring device, the monitoring device including a positioning module, a device scanning module, a first camera module, a second camera module, an information acquisition module, and a central control module, the positioning module, the device scanning module, the first camera module, the second camera module, and the information acquisition module all being connected to the central control module; the positioning module is arranged on the movable inspection device and is configured to obtain position information of the movable inspection device; the first camera module is arranged at a fixed position corresponding to a device to be detected in the thermal power plant and is configured to acquire image information of the device to be detected in the thermal power plant; the second camera module is arranged on the movable inspection device and is configured to acquire image information of the device to be detected in the thermal power plant; the device scanning module is arranged on the movable inspection device and is configured to identify the device to be detected in the thermal power plant; and the information acquisition module is configured to acquire device operation data of the thermal power plant.

[0029] In actual application, the positioning module is configured to obtain position information of the movable inspection device. The first camera module is arranged at a fixed position corresponding to a device to be detected in the thermal power plant, and the second camera module is arranged on the movable inspection device. Both the first camera module and the second camera module are configured to acquire image information of the device to be detected in the thermal power plant. The device scanning module is arranged on the movable inspection device and is configured to identify the device to be detected in the thermal power plant. The information acquisition module is configured to acquire device operation data of the thermal power plant.

[0030] In the embodiment, the positioning module can be arranged on the movable inspection device and is configured to detect position information of the movable inspection device. The positioning module can include an indoor positioning device, such as a Bluetooth positioning beacon or an Ultra-Wideband (UWB) positioning tag. When the movable inspection device works in an indoor area of the thermal power plant (such as inside a plant building), satellite signals are blocked or interfered, at which time the indoor positioning device can communicate with a corresponding base station or beacon arranged indoors to achieve accurate indoor positioning and determine the specific position of the inspection device indoors. The device scanning module can include a two-dimensional code scanner or an RFID card reader. The two-dimensional code scanner can quickly read two-dimensional code information pasted on the device, and the two-dimensional code can include detailed information of the device, such as a number, a model, and an installation position, so as to enable the inspection system to accurately identify the device. The RFID card reader reads RFID tag information installed on the device through a wireless radio frequency identification technology.

[0031] The first camera module can include a high-definition fixed camera, a lighting device, and an image transmission device. The camera has high resolution and image quality, and can continuously capture images of the equipment to be detected at a fixed angle. In a relatively dark environment, the lighting device, such as an LED lamp, can ensure that the captured images are clear and visible, and can provide sufficient lighting conditions. The image transmission device, such as an Ethernet module or a wireless transmission module, can transmit the captured image data to the central control module in real time for subsequent analysis and processing.

[0032] The second camera module can include a high-definition fixed camera, an image acquisition card, and an anti-shake device, all installed on the movable inspection device. The camera can change the shooting angle and position with the movement of the inspection device, allowing flexible shooting of different parts of the equipment, and can perform rotation, pitch, and other operations to obtain more comprehensive equipment image information. The image acquisition card (or built-in image acquisition chip) can be used to convert the analog image signals captured by the camera into digital signals for subsequent transmission and processing. The movable inspection device may

[0033] The information acquisition module can include multiple types of sensors for detecting the operating state data of the equipment. The movable inspection device can include an inspection robot or a portable inspection device. In a thermal power plant, the equipment to be detected can include boilers, steam turbines, generators, various pipelines, and electrical equipment.

[0034] The second camera module can be arranged on the top, front end, or side of the movable inspection device.

[0035] In actual application, after the movable inspection device starts working, the positioning module communicates with the positioning base station inside the thermal power plant to obtain the position information of the movable inspection device in real time and transmits it to the central control module. The central control module thus knows the specific position of the movable inspection device in the thermal power plant, providing a basis for subsequent equipment inspection path planning and data association. When the movable inspection device approaches the equipment to be detected, the equipment scanning module identifies the equipment by scanning a specific identifier (such as a two-dimensional code or an RFID tag) on the equipment and transmits the equipment information to the central control module. The central control module can determine different detection methods according to the equipment information, for example, for A-type equipment, each A-type equipment to be detected is set with a designated detection position, when the movable inspection device travels to the designated detection position, the first camera module at the fixed position receives an instruction signal to start camera work and continuously captures the state image of the corresponding A-type equipment to be detected from a preset angle.

[0036] For the B-type equipment, no designated detection position is set. When the equipment scanning module on the movable inspection device scans the equipment information, the second camera module starts to work, and the second camera module installed on the movable inspection device collects images of the equipment from different angles and distances flexibly and in detail along with the movement of the movable inspection device.

[0037] For the C-type equipment, a designated detection position is set for each C-type equipment to be detected. When the movable inspection device travels to the designated detection position, both the first camera module and the second camera module start to work to collect state images of the corresponding C-type equipment from a more comprehensive angle. The two camera modules transmit the collected image information to the central control module in real time.

[0038] For example, the A-type equipment, the B-type equipment, and the C-type equipment are different equipment. The key detection area of the A-type equipment is relatively fixed and concentrated, the important detection part of the A-type equipment is relatively regular in spatial position and angle, and the detection method is relatively standardized. Therefore, the first camera module at the fixed position can be used to collect images from a preset angle to effectively obtain the key information of the equipment state. The A-type equipment can include large stationary key equipment (such as a boiler drum) or equipment with a standard layout interface and instrument (such as a large heat exchanger).

[0039] The key detection part of the B-type equipment is not concentrated, is relatively dispersed or irregular, and is relatively complex in spatial layout. Therefore, the second camera module needs to be used to collect images from different angles and distances along with the movement of the inspection device to comprehensively capture various state information of the equipment. The B-type equipment can include small equipment with irregular shape and wide distribution (such as various small valves and pipes in a thermal power plant) or equipment with complex external structure (such as an electrical control cabinet with complex wiring and multiple small accessories). The second camera module moves along with the movable inspection device to observe each part of the B-type equipment in detail to find possible problems.

[0040] The C-type equipment has a certain regularity in the spatial key detection area. However, unlike the A-type equipment, the C-type equipment requires higher detection, and both the standard image at the fixed angle and the flexible and variable detail image need to be obtained to comprehensively judge the equipment state. The C-type equipment can include complex and key large equipment (such as a steam turbine) or equipment combination with high requirements for the running state evaluation (such as a generator set and its cooling system).

[0041] In addition, in addition to the first camera module and the second camera module collecting device images, the central control module simultaneously sends instruction information to the corresponding device to be detected to control various sensors (such as temperature sensors, pressure sensors, vibration sensors, etc.) in the information collection module to collect the operation data of the device, such as temperature, pressure, vibration amplitude, etc., which are transmitted to the collection terminal on the movable inspection device by a wireless manner, and then transmitted to the central control module by the collection terminal.

[0042] For example, the inspection robot (movable inspection device) approaches the boiler device according to the preset inspection path. The positioning module obtains the position information of the robot in real time to ensure that it accurately reaches the inspection point. After the device scanning module identifies the mark on the boiler, the first camera module captures the overall appearance image of the boiler from a fixed position to monitor the overall condition of the appearance of the boiler. The second camera module is controlled by the robot to capture detailed image information of the key parts of the boiler, such as the burner, the pipeline interface, and the furnace wall. The information collection module simultaneously collects the operation data of the boiler, such as temperature and pressure. The central control module analyzes the images and data to find that the temperature of a part of the boiler abnormally rises, and there is a color change or suspected leakage sign in the part in the image captured by the second camera module, so that alarm information can be generated to control the relevant mechanism to timely issue an alarm. Maintenance personnel can quickly locate the problem part according to the alarm information and perform further inspection and maintenance. For example, the local temperature is too high due to the blockage of a nozzle of the burner, or leakage occurs at the pipeline interface due to poor sealing. By timely discovering and processing these problems, production accidents caused by boiler failure are avoided, and the normal operation of the boiler and the power generation efficiency are ensured.

[0043] The embodiment integrates positioning, scanning, camera shooting, and information collection technologies to significantly improve the accuracy and efficiency of device monitoring. The embodiment can track the position of the inspection device in real time to ensure accurate execution of the inspection path. For different types of devices, fixed and mobile camera modules are combined to comprehensively capture device state information. For complex devices, multi-angle and detailed in-depth monitoring is achieved, and the device detection accuracy is improved. At the same time, the information collection module collects device operation data in real time, which is complementary to the image information, providing rich and accurate basis for comprehensive evaluation of the device state. Once an abnormality is found, alarm information can be generated immediately to quickly guide maintenance personnel to locate and handle the problem, effectively preventing potential failures and ensuring the safe and stable operation of the thermal power plant. In addition, the embodiment greatly reduces the burden of manual inspection, improves the level of inspection work and overall operational efficiency, and reduces maintenance costs, laying a solid foundation for the long-term sustainable development of the thermal power plant.

[0044] Preferably, the information collection module comprises a temperature detection unit, a vibration detection unit and a voltage detection unit, all of which are connected to the central control module; and the temperature detection unit, the vibration detection unit and the voltage detection unit are all arranged on the equipment to be detected in the thermal power plant.

[0045] In the embodiment, the temperature detection unit, the vibration detection unit and the voltage detection unit in the information collection module respectively collect the key parameters of the equipment to be detected in the thermal power plant through respective sensors. The temperature detection unit can use a thermosensitive element (such as a thermocouple, a thermal resistor, etc.) to perceive the temperature change of the equipment and convert it into an electrical signal for transmission to the central control module; the vibration detection unit can use an acceleration sensor or the like to detect the vibration amplitude, frequency and other information of the equipment during operation, and then convert them into transmittable data for transmission to the central control module; the voltage detection unit is connected to the circuit of the equipment, uses a voltage division or other measurement principle to obtain the voltage value of the equipment, and transmits it to the central control module. After receiving these data, the central control module analyzes and processes them, compares them with the preset normal range value, and judges whether the running state of the equipment is normal. If the data exceeds the normal range, the central control module can issue an alarm or take corresponding measures, such as arranging for maintenance, adjusting the running parameters of the equipment, etc.

[0046] For example, in the turbine inspection of the thermal power plant, the temperature detection unit is installed at the bearing and journal of the turbine to monitor the temperature in real time. If the temperature abnormally rises, it indicates that the bearing is poorly lubricated or has a friction fault. The vibration detection unit is installed at the base of the turbine to detect an increase in vibration amplitude or abnormal frequency, which indicates that the rotor is unbalanced or the parts are loose. The voltage detection unit is connected to the output circuit of the generator and other equipment to monitor whether the voltage is stable. When the voltage fluctuation exceeds the normal range, it will affect the quality of power output. According to the data transmitted by these units, the central control module can timely discover problems and notify maintenance personnel to handle them, such as oiling and lubricating the bearing, dynamic balance correction of the rotor, etc., to ensure the safe and stable operation of the turbine and the generator and other equipment, and avoid serious consequences such as power interruption or equipment damage due to equipment failure.

[0047] The information collection module in the embodiment collects the temperature, vibration and voltage data of the equipment in the thermal power plant accurately, monitors the equipment state in real time, effectively prevents faults from occurring, and improves the reliability of equipment operation. The central control module analyzes the data, responds to abnormalities quickly, provides decision support for equipment maintenance, and ensures the safe and efficient operation of the thermal power plant.

[0048] Preferably, the first camera module comprises a first camera unit and a second camera unit, both of which are connected to the central control module, the first camera unit is arranged on the first-level equipment, and the second camera unit is arranged on the second-level equipment. The first-level equipment and the second-level equipment are different equipment to be detected.

[0049] In this embodiment, the number of cameras of the first camera unit is greater than the number of cameras of the second camera unit, the volume of the primary equipment is greater than the volume of the secondary equipment, and the complexity of the primary equipment is higher than the complexity of the secondary equipment. Due to the large volume and high complexity of the primary equipment, more cameras (2-4) are needed to comprehensively monitor its running state and appearance from different angles and positions. The multiple cameras of the first camera unit are distributed around the key positions of the primary equipment, with different types of lenses such as wide-angle and telephoto lenses, to capture the overall shape of the equipment, the running details of each component, and abnormal conditions that may occur, such as the body, rotor, and blades of a large steam turbine. The secondary equipment is relatively small and simple, and the second camera unit has fewer cameras (1-2), which can include 1 camera, mainly for key parts and problem-prone points, such as the sealing of a small pump body and the wiring end of a motor. After the cameras collect images, they are transmitted to the central control module. After receiving the image data, the central control module uses image processing and analysis techniques to compare with the preset normal state standard to judge the equipment state, and once an abnormality is found, it will issue an alarm or take appropriate measures, achieving effective monitoring and management of different levels of equipment.

[0050] For example, in the boiler system of a thermal power plant, the boiler can be a primary equipment with a large and complex structure, including a burner, a furnace, steam-water pipelines, and other parts. The first camera unit can include 3 cameras installed on the front, side, and top of the boiler, respectively. The front camera monitors the flame state of the burner and the internal combustion situation of the furnace; the side camera observes the connection parts of the steam-water pipelines and whether there is deformation; and the top camera focuses on the overall running state of the boiler and whether there is any leakage sign. The feedwater pump is a secondary equipment with a relatively small volume and a relatively simple structure. The second camera unit can only need to set 2 cameras, one near the sealing of the pump body to monitor whether there is leakage, and the other aiming at the motor wiring end of the pump to check whether there is any abnormal phenomenon such as overheating or sparking. Through this configuration, different levels of equipment can be comprehensively and targetedly monitored, ensuring the safe and stable operation of the entire boiler system and timely discovering and handling possible equipment problems.

[0051] This embodiment realizes precise monitoring of equipment with different complexities by differentiating the configuration of camera units. It ensures that large and complex equipment is comprehensively monitored and small and simple equipment is key-monitored, improving the monitoring efficiency and accuracy, which helps to timely discover and handle equipment problems and ensure the safe and stable operation of the thermal power plant.

[0052] Preferably, the monitoring device further comprises an environment monitoring module connected with the central control module. Specifically, the environment monitoring module comprises a temperature and humidity detection unit and a dust detection unit, both of which are connected with the central control module.

[0053] In this embodiment, the temperature and humidity detection unit and the dust detection unit in the environment monitoring module respectively monitor the temperature and humidity and the dust condition in the thermal power plant environment in real time through built-in sensors. The temperature and humidity detection unit can use a temperature and humidity sensor to convert the changes in temperature and humidity in the environment into electrical signals and transmit them to the central control module. The dust detection unit can detect the dust concentration in the air using the optical scattering principle and transmit the data to the central control module. After receiving the temperature and humidity change data and the dust concentration, the central control module analyzes and processes them to determine whether the environment is within the normal range. If the temperature and humidity or the dust concentration exceeds the preset safety threshold, the central control module can issue an alarm or take appropriate control measures, such as starting the ventilation system, adjusting the equipment operating parameters, etc., to ensure that the thermal power plant equipment operates in a suitable environment.

[0054] For example, in a thermal power plant, the environment monitoring module works continuously. The temperature and humidity detection unit monitors the temperature and humidity of the boiler area in real time. If the temperature is higher than the temperature threshold or the humidity exceeds the humidity threshold, it will affect the combustion efficiency of the boiler and even cause equipment corrosion. After receiving abnormal data, the central control module can remind the operator to take measures, such as strengthening ventilation and heat dissipation. When the dust detection unit detects that the dust concentration in the coal conveying corridor and other areas is too high, it will increase the risk of equipment wear and explosion. The central control module can start the dust removal equipment to reduce the dust concentration and ensure the safe operation of the equipment and the health of the workers. At the same time, the environment monitoring data can also be used for long-term equipment maintenance and management decisions, such as adjusting the inspection frequency and focus according to environmental factors.

[0055] The environment monitoring module in this embodiment monitors the temperature and humidity and dust in the thermal power plant in real time to ensure that the equipment operating environment is suitable, prevent safety hazards, and improve equipment operating efficiency and lifespan. The central control module responds to abnormal data to ensure production safety and optimize maintenance strategies, providing strong support for the safe and efficient operation of the thermal power plant.

[0056] Preferably, the monitoring device further comprises a display module connected with the central control module.

[0057] In the embodiment, the display module receives data and instructions from the central control module. The display module visualizes various types of information, displays the position information of the movable inspection device in the form of a map or a chart, clearly lists the identification information of the equipment, converts the equipment operation data into intuitive numbers, charts or curves, and presents the image information in a suitable window. Through real-time connection with the central control module, the display content is constantly updated, providing the operator with real-time and comprehensive information about the state of the inspection system and the equipment, so that the operator can timely understand and judge and make corresponding decisions or operations.

[0058] For example, in the central control room of a thermal power plant, the display module is connected to the central control module. When the inspection work is in progress, the position trajectory of the inspection robot is displayed in real time on the display module. For equipment scanning information, the scanned equipment name and number are clearly displayed. The temperature, pressure and other operation data of the equipment are presented in the form of a dashboard or a column chart. At the same time, the images of the equipment collected by the first camera module and the second camera module are also displayed in the corresponding area. The operator can visually see the state of the equipment, such as discovering that the temperature of a certain equipment is too high and the image display is abnormal, so that the operator can arrange for maintenance in a timely manner to ensure the safe operation of the thermal power plant.

[0059] The display module in the embodiment displays the inspection data and the equipment state in real time, enabling the operator to intuitively understand the overall situation of the thermal power plant, quickly locate the problem equipment, and make timely decisions, thereby effectively improving the inspection efficiency and accuracy and providing a strong guarantee for the safe and stable operation of the thermal power plant.

[0060] Preferably, the monitoring device further comprises a communication module and an external monitoring terminal, and the central control module is connected to the external monitoring terminal through the communication module.

[0061] In the embodiment, the communication module serves as a bridge connecting the central control module and the external monitoring terminal. The communication module can collect various types of data from the positioning module, the equipment scanning module, the first camera module, the second camera module, the information acquisition module, etc., such as the position information of the movable inspection device, the operation data of the equipment, the image information, etc., and arrange and transmit the data. Using a suitable communication protocol (such as TCP / IP), the data is sent to the external monitoring terminal through a wired or wireless network (such as Ethernet, 4G / 5G, etc.). At the same time, the communication module can also receive instructions sent by the external monitoring terminal to the central control module, such as adjusting the inspection parameters, starting a specific detection function, etc.

[0062] For example, in a thermal power plant, when the inspection system is running, the communication module transmits the boiler temperature and pressure data collected by the inspection device and the equipment images captured by the device to the monitoring terminal in the control room in real time. The management personnel can check the equipment operation status at any time on the monitoring terminal. If an abnormal pressure of a certain boiler is found, the management personnel can send an instruction to the control module through the monitoring terminal and the communication module to make the inspection device move closer to the equipment for detailed inspection, and notify the maintenance personnel to go to handle it.

[0063] The communication module in this embodiment ensures timely information transmission and remote control, improving the inspection efficiency and the timeliness of fault handling.

[0064] Preferably, the monitoring device further comprises a fault alarm module connected with the control module.

[0065] In this embodiment, the control module receives various types of data from other modules in real time, including equipment operation data (such as temperature, pressure, vibration, etc.), image information (from the first camera module and the second camera module), and equipment identification information, etc. The control module analyzes these data and compares the received data with the pre-set normal threshold and fault mode. For example, for temperature data, if the temperature of a certain equipment exceeds the pre-set safety upper limit, a temperature alarm signal is generated and sent to the fault alarm module. When the control module analyzes and finds abnormal features in the image (such as cracks or leakage signs on the surface of the equipment), a device damage alarm signal is generated and sent to the fault alarm module. The fault alarm module starts different alarm measures according to the corresponding alarm signals transmitted by the control module and sends alarm signals through various ways. It can include popping up a prominent alarm prompt box on the display screen of the control module, displaying information such as the name, location and fault type of the faulty equipment; at the same time, sending a short message to the mobile phone or other mobile devices of the relevant staff to ensure that they can know the fault situation in time; it can also trigger a sound and light alarm to send sound and light alarms on the spot of the thermal power plant to attract the attention of nearby staff.

[0066] The fault alarm module records and stores the alarm information for subsequent tracing and analysis of the fault situation. The record can include the time of the fault occurrence, equipment information, fault type and measures taken, etc., providing important historical data for equipment maintenance and management.

[0067] The fault alarm module in this embodiment receives and analyzes the data of the control module in real time, sends alarm signals in time, notifies relevant personnel in multiple ways, ensures rapid response to faults, records fault information for tracing and analysis, provides data support for equipment maintenance and management, and effectively improves the operation and maintenance efficiency and safety of the thermal power plant.
