Description

Technical Field

[0001] The present invention relates to the technical field of equipment warehouse inspection, and in particular to an inspection method, device, computer equipment and medium for high-pressure fine water mist equipment. Background Art

[0002] A warehouse is a general term for buildings and places for keeping and storing goods. It consists of a storehouse for storing goods, transportation facilities such as cranes, elevators, slides, etc., transportation pipelines and equipment for entering and exiting the storehouse, as well as fire-fighting facilities and management rooms. Warehouses can be divided into warehouses for storing solid goods, liquid goods, gaseous goods and powdered goods according to the form of the stored goods. They can be divided into warehouses for storing raw materials, semi-finished products and finished products according to the nature of the stored goods. They can be divided into single-story warehouses, multi-story warehouses, cylindrical warehouses, etc. according to the building form. It provides space for storing goods, and the fire protection in the warehouse Safety issues are becoming increasingly serious. In order to reduce fire hazards, most warehouses are equipped with high-pressure fine water mist equipment. High-pressure fine water mist equipment uses tap water as the medium. After installation, it can spray water mist under certain high-pressure conditions. The mist particles move in three dimensions in the space in a high-speed turbulent and rotating manner. After being sprayed, they are fully entrained, broken, and atomized with the external air to produce high-speed and uniform fine water mist with a very small diameter. When a fire occurs, it can quickly spray fine water mist to the protected object or space to extinguish, suppress, control, control temperature and reduce dust. This automatic fire extinguishing system reduces fire hazards.

[0003] Since the high-pressure water mist equipment is installed in the warehouse, the warehouse needs to maintain a dry environment under normal circumstances, so the pipeline leakage of the high-pressure water mist equipment needs to be inspected. However, the existing inspection method only relies on a single mode such as shooting and text recording, which is difficult to accurately and comprehensively reflect the actual situation at the inspection site, and is prone to missing key details. It is difficult to accurately and vividly describe some complex equipment status or fault conditions, resulting in misunderstandings by subsequent processing personnel. There is a lack of strong evidence when tracing or reviewing is required, and it is difficult to accurately restore the scene at the time. The lack of multiple types of data is not conducive to in-depth data analysis and mining, and then discover potential problems and trends. Summary of the invention

[0049] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] According to an embodiment of the present invention, an inspection method embodiment of a high-pressure fine water mist device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0051] In this embodiment, a patrol inspection method for a high-pressure fine water mist device is provided, which can be used in a mobile terminal, such as a patrol inspection APP, a server, etc. The embodiment of the present invention takes the patrol inspection APP as an example to illustrate a patrol inspection method for a high-pressure fine water mist device provided in this embodiment. The patrol inspection APP structure is as follows Figure 6As shown, the inspection APP includes inspection task module, intelligent recognition module, image acquisition and processing module, audio recording module, video recording module, location positioning module, real-time communication module, data reporting module, historical query module, report generation module and knowledge base module.

[0052] The inspection task module is used for task allocation, receipt and task reminder. Administrators can assign inspection tasks through the inspection APP, and inspectors can receive and view task details. At the same time, managers can set reminders through the inspection APP to ensure that inspectors will not miss tasks.

[0053] The intelligent recognition module is used for equipment status recognition and fault mode recognition. It uses image recognition technology to automatically determine whether the equipment to be tested is working normally, and assists inspection personnel to quickly identify common equipment failure types.

[0054] The image acquisition module is used for high-definition photography and real-time annotation. It can clearly capture the status of the inspection object (such as the pipeline of high-pressure fine water mist equipment), the appearance of the equipment, etc., and can make real-time annotations on the captured pictures to point out the problems. Real-time annotations include cropping, rotation, filter addition, brightness and contrast adjustment, etc.

[0055] The audio recording module is used to record environmental sounds. The audio recording module can be implemented using a sound sensor. Recording the sound conditions on site through the inspection APP's own sound sensor helps to fully understand the inspection scenario.

[0056] The video recording module is used for video recording. It uses the inspection APP's own camera to record some complex situations or scenes that need dynamic display.

[0057] The location positioning module is used for real-time location positioning. The location positioning module is implemented using a GPS locator. The inspection APP's own GPS locator accurately locates the location of the inspection object and the inspection personnel, and records the location trajectory of the inspection personnel.

[0058] The real-time communication module is used to communicate with the command center, so that the inspection personnel can report the situation and ask questions in real time. The data reporting module is used to report equipment parameters and problem descriptions, such as recording equipment operation data and instrument readings, and describing the problems and situations found in detail. The historical query module is used to query past inspection tasks and results, including images, videos, and reported data. The report generation module is used to generate inspection reports, summarize task completion status, problems, and other information, and form professional reports. The knowledge base module is used to store common problems and solutions for easy query, and provide inspection-related knowledge and experience references.

[0059] This embodiment sets up an inspection APP to facilitate the integration of situations and problems that need to be dealt with during inspections, which is convenient for inspection personnel to query. Through multiple modalities such as images, videos, and audio, information on the inspection site can be obtained more comprehensively and accurately, avoiding the limitations of single information. Multimodal recording ensures the integrity and accuracy of the information, which facilitates the subsequent tracing and analysis of the inspection process and problems.

[0060] Figure 1 : is a flow chart of a method for inspecting a high-pressure water mist device according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0061] Step S101, obtaining an inspection task instruction, and assigning an inspection task based on the inspection task instruction.

[0062] Specifically, an inspection task instruction is issued through the inspection task module of the inspection APP. After the inspection task instruction is issued, the inspection task is assigned to the inspection personnel based on the inspection task instruction.

[0063] Step S102, based on the inspection task, collects the pipeline video information of the high-pressure fine water mist equipment in the inspection area, and performs a target inspection on the pipeline of the high-pressure fine water mist equipment in the inspection area based on the pipeline video information and image processing technology to obtain a target inspection result.

[0064] Specifically, the area to be inspected can be a warehouse, where a high-pressure fine water mist device is installed. Taking the warehouse as an example, based on the assigned inspection task and using the image acquisition and processing module to record the video of the pipeline of the high-pressure fine water mist device in the warehouse, the pipeline video information is obtained, and the image processing technology is used to identify the pipeline of the high-pressure fine water mist device in the inspection area, determine whether the pipeline is leaking, and obtain the target inspection result.

[0065] Step S103, based on the target inspection result, regular inspection and / or special inspection are performed on the pipeline corresponding to the high-pressure fine water mist equipment to obtain regular inspection results and special inspection results respectively.

[0066] Specifically, regular inspections refer to inspections of warehouses at prescribed time intervals. Regular inspections include random inspections of personnel who are inspecting to prevent personnel paralysis. Special inspections focus on key locations and key pipelines of high-pressure fine water mist equipment in warehouses, and special inspections are carried out in strict accordance with standards and procedures.

[0067] Based on the target inspection result of whether the pipeline is leaking, regular inspection and / or special inspection are performed on the pipeline corresponding to the high-pressure fine water mist equipment to obtain regular inspection results and special inspection results respectively.

[0068] Step S104, summarize the regular inspection results and the special inspection results, and generate an inspection report based on the summary results.

[0069] Specifically, the report generation module of the inspection APP is used to summarize the results of regular inspections and special inspections, and the problems arising during the inspection and the special conditions of the pipeline are recorded in writing in the inspection notebook, marking the time and place of the inspection, recording the signatures of the inspection personnel, and generating an inspection report based on the summarized inspection results. The inspection report can be presented in the form of a report.

[0070] The inspection method for high-pressure fine water mist equipment provided in the present embodiment collects status pipeline video information of the high-pressure fine water mist equipment in the area to be inspected based on the inspection task, and performs targeted inspection on the pipelines of the high-pressure fine water mist equipment in the area to be inspected based on the pipeline video information and image processing technology to obtain targeted inspection results; based on the targeted inspection results, regular inspections and / or special inspections are performed on the corresponding pipelines of the high-pressure fine water mist equipment to obtain regular inspection results and special inspection results, respectively, and adopts multiple modal inspection methods for the pipelines of the high-pressure fine water mist equipment, so as to accurately and efficiently judge the operation status of the pipelines of the high-pressure fine water mist equipment, summarize the regular inspection results and the special inspection results, and generate an inspection report based on the summarized results, which is conducive to later tracing or review, can accurately restore the inspection scene, can conduct in-depth data analysis and mining, and then discover potential problems in the area to be inspected, and solves the problem that the inspection mode in the prior art is single and it is difficult to accurately and comprehensively reflect the actual situation of the inspection site of the high-pressure fine water mist equipment.

[0071] In this embodiment, a method for inspecting a high-pressure fine water mist device is provided, which can be used in a mobile terminal, such as an inspection APP, a server, etc. Figure 2 : is a flow chart of a method for inspecting a high-pressure water mist device according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0072] Step S201, obtain inspection task instructions, and assign inspection tasks based on the inspection task instructions. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0073] Step S202 is to conduct a visual inspection of the warehouse environment, check whether the monitoring equipment in the inspection area is operating normally, and conduct a preliminary inspection of the key pipelines of the high-pressure fine water mist equipment by listening to the sound.

[0074] Specifically, during the visual inspection, the environment and scene changes in the warehouse are checked with the naked eye. After the visual inspection is completed, instrument inspection is required to determine whether the monitoring equipment (such as shooting equipment) can operate normally. After the instrument inspection is completed, document review is required. The location of the pipelines in the warehouse and the pipelines that need attention can be inquired through the warehouse map carried. After the document review is completed, it is necessary to judge by listening to the sound of the pipeline to estimate whether the pipeline is operating normally.

[0075] Step S203, based on the inspection task, collect the pipeline video information of the high-pressure fine water mist equipment in the inspection area, and perform target inspection on the pipelines of the high-pressure fine water mist equipment in the inspection area based on the pipeline video information and image processing technology to obtain the target inspection result.

[0076] Specifically, pipeline video information is obtained by capturing video of pipeline gaps and the entire pipeline; image processing technology includes image preprocessing and feature extraction, such as Figure 5 As shown, the above step S203 includes:

[0077] Step S2031, performing image preprocessing on the pipeline video information to obtain a denoised grayscale video image.

[0078] Specifically, the image acquisition and processing module of the inspection APP is used to pre-process the pipeline video information, including improving image quality, removing noise, and image cropping. Improving image quality is to convert color images into grayscale images, removing noise is to improve the noise in the video to facilitate video viewing, and image cropping is to change the image size and adjust the direction of the image.

[0079] Step S2032, extracting features from the grayscale video image to obtain key video features.

[0080] Specifically, after the image preprocessing is completed, feature extraction is performed on the obtained grayscale video image. Feature extraction includes pipeline gap magnification and corner point detection, where pipeline gap magnification is to magnify the details of the pipeline surface in the grayscale image, and corner point detection is used for image alignment and matching to help identify key video features.

[0081] Step S2033, performing a target inspection on the pipeline based on the key features of the video, and obtaining a target inspection result of a pipeline leak or a target inspection result of a pipeline not leaking.

[0082] Specifically, based on the key features of the video, target recognition is performed on the features in the video to determine whether the pipeline is leaking, and a target inspection result of pipeline leakage or a target inspection result of pipeline non-leakage is obtained. In an optional embodiment, when the target inspection result of pipeline leakage is obtained, a text description of the pipeline leakage is made, and the leakage point, leakage location and leakage area size are marked in the pipeline video information.

[0083] Step S204: Perform regular inspection and / or special inspection on the pipeline corresponding to the high-pressure water mist device based on the target inspection result, and obtain regular inspection results and special inspection results respectively. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0084] It should be noted that when conducting targeted inspections, regular inspections and / or special inspections, the inspection location and the pipeline location of the high-pressure fine water mist equipment are located, and the inspection location trajectory is recorded. The specific implementation is: the location positioning module in the APP is used to help the inspection personnel quickly find the target location, with a navigation function, accurately display the current location of the inspection personnel or pipeline, record the inspection location trajectory, facilitate tracing, ensure personnel safety, and respond to abnormal situations in a timely manner.

[0085] Step S205: Summarize the regular inspection results and special inspection results, and generate an inspection report based on the summary results. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0086] The inspection method of the high-pressure fine water mist equipment provided in this embodiment facilitates the timely discovery of potential safety hazards, early discovery of pipeline leaks, and clarification of the inspection time and route, thereby improving the efficiency of the inspection, by visually inspecting the warehouse environment, detecting whether the monitoring equipment in the inspection area is operating normally, and conducting a preliminary inspection of the key pipelines of the high-pressure fine water mist equipment by listening to the sound. By image preprocessing, the image quality is improved to remove noise and ambiguity in the pipeline video information, so that the status of the pipeline can be observed more quickly, and a better basis is provided for the target inspection of the pipeline based on the key features of the video to obtain the target inspection results of the pipeline leakage or the target inspection results of the pipeline without leakage, which effectively improves the quality and processability of the picture and improves the accuracy of identifying pipeline leakage. By image annotation, various types of annotations or labels are added at the key points of the video so that the pipeline video information can be understood and processed later. When the video has clear semantic information, the leakage point of the pipeline can be accurately judged, and the recognizability of the pipeline leakage point is increased.

[0087] In this embodiment, a patrol inspection method for a high-pressure fine water mist device is provided, which can be used for the above-mentioned mobile terminal, such as a patrol inspection APP, a server, etc. Figure 3 : is a flow chart of a method for inspecting a high-pressure water mist device according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0088] Step S301, obtain inspection task instructions, and assign inspection tasks based on the inspection task instructions. Figure 2Step S201 of the illustrated embodiment will not be described in detail here.

[0089] Step S302: Based on the inspection task, collect the pipeline video information of the high-pressure fine water mist equipment in the inspection area, and perform a target inspection on the pipelines of the high-pressure fine water mist equipment in the inspection area based on the pipeline video information and image processing technology to obtain the target inspection result. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0090] Step S303: Perform regular inspection and / or special inspection on the pipeline corresponding to the high-pressure water mist device based on the target inspection result, and obtain regular inspection results and special inspection results respectively. Figure 2 Step S204 of the illustrated embodiment will not be described in detail here.

[0091] Step S304, setting an inspection route, and performing multi-person cross inspections on pipelines that have not been inspected in the inspection area based on the inspection route, so as to determine the pipeline leakage of the high-pressure fine water mist equipment that has not been inspected in the inspection area.

[0092] Specifically, after the special inspection is completed, it is necessary to set up the inspection route and plan the pipeline routes that have not been inspected. After the inspection route is set, multiple people are required to conduct cross-inspections. By collaborating to inspect pipelines on different routes, the subjective judgment errors of a single person can be reduced. At the same time, they can supervise each other and reduce negligence during inspections.

[0093] Step S305, summarize the regular inspection results and the special inspection results, and generate an inspection report based on the summary results.

[0094] Specifically, the results of regular inspections and special inspections are summarized, and then historical inspection records are obtained. The regular inspection results and special inspection results are compared and analyzed with the historical inspection records to obtain inspection comparison and analysis results. The regular inspection results, special inspection results, and comparative analysis results are summarized and recorded in the inspection notebook by writing, marking the time and place of the inspection, and recording the signature of the inspection personnel. Based on the above information, an inspection report is generated to facilitate clear responsibilities. When recording the inspection results, attention should be paid to maintaining the integrity and authenticity of the records to better support the implementation of the inspection work and the normal operation of the equipment.

[0095] The inspection method for high-pressure fine water mist equipment provided in this embodiment improves the inspection quality by setting up multi-person cross-inspections. The perspectives and experiences of different personnel can discover more problems, increase the rigor of the inspection, promote communication and learning between personnel, improve work efficiency and quality, ensure the normal operation of pipelines, ensure warehouse safety, obtain historical inspection records, and compare and analyze the results of regular inspections and special inspections with the historical inspection records to obtain inspection comparison and analysis results, which is conducive to comparing the current inspection results with the historical inspection records, helping to discover potential problems and trends, facilitating subsequent inquiries and references, and can serve as a basis for assessment and improvement.

[0096] It should be noted that the inspection APP used in the inspection method of the high-pressure fine water mist device provided in this embodiment is also connected to the control center, which can be a computer, server, smart home device, etc., so as to facilitate the transmission of video image information and inspection content involved in the inspection process to the control center. In order to connect with the control center, taking the control center using smart home devices as an example, it is also necessary to design the interface and data fusion of the inspection APP, specifically including: the first data acquisition interface design, including determining the multimodal data type to be collected, such as hardware information, software information, system information, application information, user behavior and environmental factors, etc., and designing a corresponding data acquisition interface for each data type, which may include a direct communication interface with smart home devices (such as Bluetooth, Wi-Fi), an interface for obtaining information from the device operating system, and a connection interface with an environmental sensor, etc., to ensure the compatibility and stability of the interface, and to be able to work normally on different smart home devices and operating systems.

[0097] The second data fusion framework is built, including establishing a data fusion framework for integrating multimodal data from different interfaces and selecting appropriate data fusion algorithms and models, such as weighted averaging, rule-based fusion, feature fusion methods in machine learning, etc.

[0106] As one or more specific application embodiments of the present invention, Figure 4 The inspection method of the high-pressure fine water mist equipment provided by the present invention is further described in detail, and the specific process is as follows:

[0107] S1. Conduct a preliminary inspection of the warehouse environment by visually inspecting whether the monitoring equipment in the inspection area is operating normally, and by listening to the key pipelines of the high-pressure fine water mist equipment. Specifically, during the visual inspection, the environment and scene changes in the warehouse are inspected by naked eyes. After the visual inspection is completed, instrument inspection is required to determine whether the shooting equipment can operate normally. After the instrument inspection is completed, document review is required to query the location of the pipelines in the warehouse and the pipelines that need attention through the warehouse map carried. After the document review is completed, it is necessary to listen to the sound and estimate whether the pipeline is operating normally based on the sound of the pipeline.

[0108] S2. After the audio judgment is completed, image acquisition is required. Mobile phones, cameras and other devices are mainly used to shoot videos of the gaps in the pipeline and the entire pipeline. After the image acquisition is completed, the captured video needs to be preprocessed, including improving image quality, removing noise, and image cropping. Improving image quality is to convert color images into grayscale images, removing noise is to improve the noise in the video to facilitate video viewing, and image cropping is to change the image size and adjust the direction of the image.

[0109] S3. After image preprocessing is completed, feature extraction is required, including pipeline gap magnification and corner point detection. Pipe gap magnification is to magnify the details of the pipeline surface, and corner point detection is used for image alignment and matching to help identify key features of the video.

[0110] S4. After feature extraction is completed, it is necessary to identify the features in the video to determine whether the pipeline is leaking. Then image annotation is required. Image annotation includes text description to mark the leakage point, leakage location, and leakage size in the identified video.

[0111] S5. After the image acquisition is completed, regular inspections are required. The warehouse should be inspected at the specified time intervals. Regular inspections include random inspections, which are carried out on personnel who are inspecting to prevent personnel paralysis. After the random inspection is completed, special inspections are required, focusing on key locations and special pipelines, and inspections must be carried out strictly in accordance with standards and procedures.

[0112] S6. After the special inspection is completed, it is necessary to set up the inspection route and plan the pipeline routes that have not been inspected. After the inspection route is set, multiple people are required to conduct cross-inspections. By collaborating with multiple people to inspect pipelines on different routes, the subjective judgment error of a single person can be reduced. At the same time, they can supervise each other and reduce negligence during inspections.

[0113] S7. After the multi-person cross inspection is completed, the inspection personnel can use the inspection APP to assist the inspection personnel in the inspection work again to ensure that the inspection work is carried out on time. Real-time records can reduce the tediousness of paper records. Communication through Bluetooth devices facilitates the inspection personnel on different routes to analyze and communicate on the conditions of the pipeline.

[0114] S8. The location positioning module in the inspection APP helps inspection personnel quickly find the target location. It has a navigation function, accurately displays the current location of personnel or pipelines, records the movement path, facilitates traceability, ensures personnel safety, and responds to abnormal situations in a timely manner.

[0115] S9. Compare and analyze the inspection results, compare and summarize the problems arising during the inspection with those that occurred during previous inspections, and record the inspection results.

[0116] S10. After the comparative analysis is completed, the inspection results need to be recorded. The problems generated during the inspection and the special conditions of the pipeline should be recorded in the inspection notebook in writing, and the time and place of the inspection should be marked. The signatures of the inspectors should be recorded to facilitate the clarification of responsibilities. When recording the inspection results, attention should be paid to maintaining the integrity and authenticity of the records in order to better support the implementation of the inspection work and the normal operation of the equipment. The inspection method of the high-pressure fine water mist equipment provided in this embodiment is convenient for integrating the situations and problems that need to be handled during the inspection by setting up an inspection APP, which is convenient for the inspection personnel to query. Through multiple modes such as images, videos, and audio, the information of the inspection site can be obtained more comprehensively and accurately, avoiding the limitations of single information. Multimodal recording ensures the integrity and accuracy of the information, which is convenient for the subsequent tracing and analysis of the inspection process and problems.
