DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 8 The present invention provides a technical solution: a new energy station safety inspection management system, including an intelligent control terminal and an inspection device 1, the intelligent control terminal includes a task scheduling and management module 2, an intelligent data analysis platform 3 and a remote monitoring center 4, the inspection device 1 and the task scheduling and management module 2 are connected to the remote monitoring center 4 through signals.

[0027] It should be noted that the remote monitoring center 4 includes a real-time monitoring interface provided by the remote monitoring center to display the inspection status, equipment status and environmental parameters of the new energy station. The interface supports operations such as zooming and dragging, which is convenient for users to view the inspection status of different areas; at the same time, users can remotely dispatch and control the inspection equipment 1 through the remote monitoring center 4, such as adjusting the inspection route, pausing / resuming the inspection task, etc., and support real-time monitoring and fault diagnosis of the equipment status; at the same time, the remote monitoring center 4 integrates video monitoring functions, and users can intuitively understand the actual situation in the station through the monitoring screen. Video monitoring supports video playback and screenshot functions, which is convenient for users to trace and analyze events.

[0028] The intelligent data analysis platform 3 receives the data from the inspection equipment 1, performs pre-processing operations such as data cleaning and denoising to ensure the accuracy and reliability of the data; and uses big data and artificial intelligence algorithms (such as machine learning, deep learning, etc.) to conduct in-depth analysis of the pre-processed data to identify equipment anomalies and potential faults. The algorithm model is trained based on historical data, and is continuously optimized and adjusted to improve the recognition accuracy. When equipment anomalies or potential faults are identified, the intelligent data analysis platform automatically generates alarm information and notifies relevant personnel for processing through SMS, email, APP push, etc. Finally, the inspection data, analysis results and alarm information can be stored in the database system, supporting data query, statistics and analysis functions, and providing data support for operation and maintenance management.

[0029] Task Scheduling and Management Module 2 According to the inspection needs and equipment status of the new energy stations, the task scheduling and management module automatically generates inspection tasks and intelligently allocates them to various inspection equipment. During the allocation process, multiple factors such as equipment status, inspection history, and personnel skills are considered to achieve optimal task allocation, and a task progress tracking function is provided to display the execution status and progress of inspection tasks in real time. Users can view information such as task status and remaining time through the interface to ensure that the inspection tasks are completed on time. After the inspection task is completed, the task scheduling and management module collects task execution results and user feedback to evaluate and optimize the task effect. The evaluation results are used to guide the generation and allocation of subsequent tasks.

[0030] See also Figure 2 and Figure 3 The inspection equipment 1 includes an inspection track 101, which is fixedly connected to the wall and equipment in the station through a plurality of connectors 102. A plurality of installation boxes 103 are installed on the inspection track 101, and every two adjacent installation boxes 103 are connected by a connecting structure.

[0031] The overall direction of the inspection track 101 is set according to the inspection route, and the inspection track 101 is fixedly connected to the wall or equipment in the station through the connecting piece 102, so that the vibration of the wall or equipment in the station can be transmitted to the inspection track 101 through the connecting piece 102, and finally transmitted to the installation box 103 for easy detection. The installation box 103 can move on the inspection track 101 along the extension direction of the inspection track 101, so as to inspect the station.

[0032] See also Figures 4 to 8, each installation box 103 has a rotating shaft 104 rotatably connected to both sides of the bottom surface, and one end of each rotating shaft 104 is fixedly connected to a roller 105, and each roller 105 is engaged with a recessed structure arranged on the surfaces of both sides of the inspection track 101, and the other ends of the two rotating shafts 104 extend into the interior of the installation box 103, and one end of one of the rotating shafts 104 is fixedly sleeved with a driven gear 106, and the driven gear 106 is meshed and connected with a driving gear 107 on one side, and the driving gear 107 is fixedly sleeved on one end of the output shaft of the motor 108, and the motor 108 is fixedly mounted on the inner wall of one side of the installation box 103.

[0033] The starting motor 108 can drive the driving gear 107 to rotate, and the corresponding rotating shaft 104 can be driven to rotate through the meshing connection relationship between the driving gear 107 and the driven gear 106, so that the corresponding roller 105 can rotate, and the roller 105 drives the installation box 103 to move as a whole on the inspection track 101.

[0034] Furthermore, a power supply module 109 is fixedly installed on the inner wall of one side of each installation box 103, and a remote communication module 110 is fixedly installed on the inner wall of the other side of the installation box 103. The remote communication module 110 is electrically connected to the power supply module 109, and the remote communication module 110 is signal-connected to the task scheduling and management module 2, the intelligent data analysis platform 3 and the remote monitoring center 4. An electric pan-tilt head 111 is fixedly installed on the top surface of the installation box 103, and a patrol camera 112 is installed on the electric pan-tilt head 111. An infrared thermal imager 113 is fixedly installed on the surface of one side of the patrol camera 112. A sensor module 114 is fixedly installed on the surface of one side of the installation box 103, and the sensor module 114, the infrared thermal imager 113, the patrol camera 112, the motor 108 and the electric pan-tilt head 111 are all electrically connected to the remote communication module 110 and the power supply module 109.

[0035] The power supply module 109 supplies power to the detection equipment, motor 108 and remote communication module 110 installed on the entire installation box 103. The remote communication module 110 transmits the detection signal collected by each detection device to the intelligent data analysis platform 3 for integration, analysis and recording. The electric pan / tilt head 111 can drive the inspection camera 112 and the infrared thermal imager 113 to adjust the angle and direction, so that the installation box 103 can move on the inspection track 101 while photographing the environment and equipment in the station. At the same time, the sensor module 114 integrates temperature sensors, humidity sensors, vibration sensors and other corresponding sensors that need to detect the environment and equipment in the station. The installation box 103 moves along the inspection track 101 to detect the environment and equipment in the station.

[0036] Furthermore, each connection structure includes a quick-release connection assembly and a fixed connection portion fixedly connected to the two side surfaces of the corresponding installation box 103, each fixed connection portion includes two mounting plates 116, and the two mounting plates 116 are respectively fixedly connected to the two opposite side surfaces of the corresponding installation box 103, and a connecting seat 117 is integrally provided on one side surface of each mounting plate 116, and the connecting seat 117 is rotatably connected to one end of the hinged plate 118, and a connecting rod 119 is integrally provided on the other end surface of the hinged plate 118, and the two opposite connecting rods 119 are detachably connected via a quick-release connection assembly.

[0037] The hinged plate 118 can rotate independently relative to the connecting seat 117, so that when several installation boxes 103 are connected together, only two rollers 105 are set under each installation box 103, which can smoothly pass through the curved part of the inspection track 101, avoiding the situation where the installation box 103 cannot move due to the insufficient angle of the curved part of the inspection track 101. At the same time, after two adjacent installation boxes 103 are connected together by a quick-release connection assembly, the angle in the vertical direction can also be adjusted, so that the movement can be smooth even when the inspection track 101 has ups and downs.

[0038] Furthermore, each quick-release connection assembly includes a shell 115, and two groups of connection mechanisms corresponding to the connecting rod 119 are arranged inside the shell 115, and each group of connection mechanisms includes two parallel distributed connection frames 120. Limiting grooves 121 are provided on both side surfaces of the shell 115. One end of each connection frame 120 extends to the outside of the shell 115 through the limiting groove 121 on the corresponding side and is integrally provided with a connecting ring corresponding to the two ends of the connecting rod 119. A threaded hole is provided on one end of each connection frame 120 located inside the shell 115. The two connection frames 120 in the same group are respectively threadedly connected to the two ends of the first bidirectional screw 122 through the threaded holes. The first bidirectional screw 122 is rotatably installed between the inner walls on both sides of the mounting frame 123, and each first bidirectional screw 122 is also connected to the corresponding driving mechanism.

[0039] By driving the first bidirectional screw 122 to rotate through the driving mechanism, the two connecting frames 120 in the corresponding group can be driven to synchronously reversely move along the extension direction of the limiting groove 121, so that the connecting rings set at the ends of the two connecting frames 120 are set on the two ends of the connecting rod 119. While completing the connection with the corresponding installation box 103, the installation box 103 and the outer shell 115 can also be adjusted in the longitudinal direction. The angle, so that the whole can be affected by the up and down extension of the inspection track 101.

[0040] Furthermore, each driving mechanism includes a worm gear 124 fixedly mounted on the first bidirectional screw 122, the worm gear 124 is meshingly connected to a worm 125 on one side, one end of the worm 125 is rotatably connected to the bottom inner wall of the corresponding mounting frame 123, and the other end of the worm 125 extends to the outside of the outer shell 115 through an extension groove 126 opened on the top surface of the outer shell 115.

[0041] By rotating the worm 125 to drive the worm wheel 124 to rotate, the first bidirectional screw 122 can be rotated, and the distance between the two connecting frames 120 can be adjusted to achieve connection and separation with the connecting rod 119. At the same time, the connection between the worm wheel 124 and the worm 125 has a self-locking effect, which can ensure the connection stability to a certain extent and reduce the situation where several installation boxes 103 are disconnected during the inspection process.

[0042] Furthermore, a damping structure is provided at the rotational connection between each worm 125 and the corresponding mounting frame 123 .

[0043] Limiting the worm 125 by a damping structure can further improve the connection stability.

[0044] Furthermore, a slider 127 is integrally provided on the bottom surface of each mounting frame 123. Each slider 127 is slidably installed in a corresponding guide groove 128. Two guide grooves 128 are opened through the bottom surface of the shell 115. A screw hole is opened on one end surface of each slider 127. The two sliders 127 are respectively threadedly connected to the two ends of the second bidirectional screw 129 through the screw holes. The second bidirectional screw 129 is rotatably installed on one end of the connecting plate 130. The other end of the connecting plate 130 is fixedly connected to the bottom surface of the shell 115.

[0045] The spacing between the two sliders 127 can be adjusted by rotating the second bidirectional screw 129, thereby changing the length of the outer shell 115 where the connecting frame 120 extends, so that the distance between two adjacent installation boxes 103 can be adjusted according to actual use needs to increase the applicable scenarios and reduce usage limitations.

[0046] Working principle: The task scheduling and management module 2 is responsible for formulating inspection plans and allocating inspection equipment 1 according to inspection needs and station layout. This includes determining the inspection route, inspection frequency, inspection content, etc. Through the remote monitoring center 4, managers can monitor the operating status and inspection progress of the inspection equipment in real time to ensure that the inspection tasks are carried out as planned. Several installation boxes 103 in the inspection equipment 1 can be moved on the inspection track 101 by starting the motor 108. During the movement, the status data and environmental parameters of the new energy station facilities are collected in real time through the sensor module 114, the inspection camera 112 and the infrared thermal imager 113. These data include the temperature, humidity, vibration, appearance, etc. of the equipment, and the detection signal is transmitted to the intelligent data analysis platform 3 and the remote monitoring center 4 through the remote communication module 110 for analysis and recording. This process ensures the timeliness and accuracy of the data. To ensure inspection efficiency and reduce inspection errors, several installation boxes 103 can be connected through a connecting structure so that several installation boxes 103 drive various detection equipment to perform multiple inspections along the same route to eliminate errors in the detection process and improve accuracy.

[0047] It should be noted that the specific models and specifications of the motor 108, power supply module 109, remote communication module 110, electric pan / tilt head 111, inspection camera 112, infrared thermal imager 113, sensor module 114, task scheduling and management module 2, intelligent data analysis platform 3 and remote monitoring center 4 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.
